The invention relates to transportable modules and/or vehicle enclosures suitable for spraying and baking vehicles.
The closest prior art is the Applicant's own prior patent publication WO2014/016606 which discloses a transportable enclosure suitable for spraying and baking a vehicle. It teaches the use of a single module in which both the air handling unit and the vehicle receiving portion are provided. These vehicle enclosures may be rapidly configured for spraying and baking. They are particularly versatile and may be deployed in a wide variety of settings on a permanent or semi-permanent basis. They allow high quality spraying and baking to take place without requiring extensive infrastructure such as a vehicle hanger in which multiple spraying and baking stations may be provided. Neither the Applicant's own prior art nor the construction of large hangers are practical when spraying and baking large structures or vehicles such as trains. One of the objectives of certain embodiments of the invention is to provide a rapidly deployable structure which may be advantageously transported to a site and deployed as a station for treating large vehicles such as trains or the like.
In a first broad independent aspect, embodiments of the invention provide a transportable module which when deployed forms at least part of a vehicle enclosure, said transportable module comprising a first housing which houses at least part of an air handling unit, said housing comprising a rigid side wall or a rigid roof portion which is extendible to form at least part of an additional housing adjacent to said air handling unit; said additional housing being suitable for housing and fully enclosing a vehicle; whereby spraying and baking operations may be carried out within said additional housing whilst said vehicle is shielded from the surrounding environmental conditions; said air handling unit being configured to heat and/or cool air in order to provide heated or cooled air to the vicinity of said vehicle; and an extraction duct for removing air from said additional housing and for filtering said removed air prior to disposing of it into the surrounding environment. This configuration is particularly advantageous as it provides for particularly compact transportation of the enclosure and its efficient deployment on site.
In a further broad independent aspect, the invention provides a transportable module which when deployed forms at least part of a vehicle enclosure, said transportable module comprising a housing which houses at least part of an air handling unit, a side wall portion which is stackable adjacent to the housing during transportation and which is deployable to project upwards from the housing, a roof portion which is also stackable with respect to the housing during transportation and which is deployable to form a roof whilst resting on at least part of the side wall portion. This configuration is particularly advantageous because the module may be transported on roads by an appropriate vehicle transporter such as a truck or lorry. It also provides embodiments which are particularly stable in severe weather conditions whilst providing the protection sought after for spraying and baking operations. It allows in particular the shielding of much larger structures than the volume occupied during transportation.
In a subsidiary aspect, the side wall portion is stacked above the housing and is pivotally secured to the housing. This allows the module to be rapidly deployed and in certain embodiments double or more than double the height of the deployed structure.
In a subsidiary aspect, the roof portion is stacked above the side wall portion and is pivotally secured to the side wall portion. This allows the expansion of the module in more than one dimension which considerably increases the achievable volume for receiving a vehicle.
In a further subsidiary aspect, the module comprises an actuator for driving a deployment of the side wall portion. This configuration provides a much more efficient deployment of the module into a vehicle enclosure of the kind required.
In a further subsidiary aspect, the actuator comprises a hydraulic ram extending between the housing and the side wall which when activated causes the side wall portion to pivot from a position where the side wall portion lays substantially flat on top of the housing to an erect position where the side wall portion extends upwards from the housing. This configuration is particularly advantageous in increasing the achievable volume of the enclosure formed by modules of the kind in question.
In a further subsidiary aspect, the module comprises an actuator for driving the deployment of the roof portion. This configuration provides an advantageously rapid deployment and transition from the transportable module to the vehicle enclosure. This approach is also believed to increase the safety of the deployment operation.
In a subsidiary aspect, the actuator comprises a hydraulic ram extending between the side wall portion and the roof portion which when activated causes the roof to pivot from a position where it lies against the side wall portion to a position where it extends laterally therefrom. This provides an advantageous safe and rapid expansion of the achievable enclosure volume.
In a further subsidiary aspect, the side wall portion incorporates one or more air ducts through which air flows from the air handling unit to an inlet through which heated air enters a vehicle receiving portion when an enclosure is formed in part by the deployed module. This is particularly advantageous in order to provide advantageous airflow from an uppermost portion of the formed vehicle enclosure which will allow the air to be drawn over the entire height of the side of a train, should a train be positioned in the vehicle enclosure.
In a further subsidiary aspect, the housing comprises an extraction duct through which air in an enclosure formed in part by the deployed module may be drawn out of the vehicle receiving portion of the enclosure. This allows advantageous capture of air for removal from the vehicle enclosure.
In a further subsidiary aspect, the housing comprises a fan for driving the circulation of air through the air handling unit and a vehicle receiving portion when an enclosure is formed in part by the deployed module.
In a further subsidiary aspect, the housing comprises a burner for heating air at a first temperature level suitable for spraying paint onto a vehicle and at a second temperature level suitable for baking the paint. This configuration is particularly advantageous as it allows the formed enclosure to reach both spraying and baking appropriate temperatures.
In a further subsidiary aspect, the air handling unit comprises a heat exchanger for cooling air to a temperature suitable for spraying paint onto a vehicle.
In a further subsidiary aspect, the housing comprises a first wall located towards the front of the housing, a second wall located to one side of the housing, a third wall located towards the rear of the housing and a fourth wall located to one side of the housing; said deployable side wall portion being provided above the second side wall. This configuration provides a particularly robust structure from a load bearing perspective. Advantageously, the side wall portion may be in line with the second side wall in order to maximise its load bearing capabilities.
In a further subsidiary aspect, the air handling unit is adjacent to the second side wall. This is particularly advantageous as it provides spacing between the air handling unit and the first side wall which may be occupied by other kinds of equipment, for example a compressor system or a paint mixing room.
In a further subsidiary aspect, the module comprises a floor portion above which the air handling unit is provided; the floor portion being configured to carry the air handling unit. This configuration is particularly advantageous in terms of transporting the module as a single integrated piece.
In a subsidiary aspect, the housing comprises side walls, a roof and floor portions which each include a plurality of structural beams extending in respective orthogonal axes; the air handling unit being provided within the housing. In certain embodiments, this provides a particularly lightweight structure as the beams bear most of the stresses and strains associated with lifting the transportable module whilst additional side walls may be provided in certain embodiments to enclose the spaces between respective beams. These additional side walls may therefore only have a secondary load bearing function.
In a further subsidiary aspect, the housing comprises one or more separate rooms in addition to any room within which the air handling unit is located. This provides additional potentially segregated spaces for paint mixing rooms, an office, or a compressor system.
In a further subsidiary aspect, the module further comprises a deployable floor portion which during transportation may be positioned against the housing and which is deployable into a position where the floor portion extends laterally from the housing. This optional feature may be useful if the vehicles in question themselves are large trucks or lorries instead of trains, locomotives and/or their waggons which are potentially transported on their rails. Floor portions may be advantageous for capturing unused droplets of paint and other substances. For certain embodiments, the floor portion may also incorporate an air duct for extraction in a similar fashion as that described previously with respect to the deployable side wall.
In a further broad aspect, the invention provides a spraying and baking vehicle enclosure being formed by at least two deployed modules according to any of the preceding aspects, wherein respective roof portions of the deployed modules are secured to one another in order to form a vehicle receiving portion. This configuration is particularly advantageous as it allows with as little as only two modules the formation of a vehicle receiving portion, which is more than four times the volume of each module. This allows a vehicle enclosure to be deployed very rapidly at most sites of a rail network which may also contribute to a reduction in potential disruption of the downtime for a particular train in need of painting and/or refurbishing.
In a subsidiary aspect, the enclosure comprises a vehicle entrance formed between the deployed modules and one or more closure members capable of selectively closing the vehicle entrance. Optionally, the closure members may be part of a roller blind system. This provides a particularly weather-proof vehicle enclosure which may be advantageously readily transported on a transporter.
In a further subsidiary aspect, the enclosure comprises a vehicle exit formed between the deployed modules and one or more closure member capable of selectively closing the vehicle exit. Optionally, one or more closure members may incorporate a roller blind system which is particularly advantageous for transportation within the transportable module for example in a compartment provided in the housing.
In a further broad aspect, embodiments of the invention provide a transportable module which when deployed forms at least part of a vehicle enclosure, the transportable module comprising a first housing which houses at least part of an air handling unit, and a second or additional housing being suitable for housing and fully enclosing a vehicle; whereby spraying and baking operations may be carried out within said additional housing whilst said vehicle is shielded from the surrounding environmental conditions; the air handling unit being configured to heat and/or cool air in order to provide heated or cooled air to the vicinity of the vehicle; and an extraction duct for removing air from the additional housing and for filtering the removed air prior to disposing of it into the surrounding environment; wherein a wall is provided between the air handling unit and the additional housing; the wall closing one end of the additional housing.
In a further broad aspect, embodiments of the invention provide a transportable module which when deployed forms at least part of a vehicle enclosure, the transportable module comprising a first housing which houses at least part of an air handling unit, and an additional housing being suitable for housing and fully enclosing a vehicle; whereby spraying and baking operations may be carried out within the additional housing whilst the vehicle is shielded from the surrounding environmental conditions; the air handling unit being configured to heat and/or cool air in order to provide heated or cooled air to the vicinity of the vehicle; and an extraction duct for removing air from the additional housing and for filtering the removed air prior to disposing of it into the surrounding environment; wherein the first housing is displaceable from a first position where it is located within the additional housing to a second position where it is located partially above or to one side of said additional housing; whereby the usable interior space of said additional housing is expanded.
Nevertheless, since in preferred embodiments both modules are identical, the detailed description will be provided with respect to transportable module 2. Transportable module 2 incorporates a housing 4 with a front wall 5 (see
The air handling unit employs a fan 17 which may draw fresh air in through a fresh air duct 18 and through a heat exchanger 19 for heating the air at either a level suitable for a spraying temperature within the enclosure or a baking temperature as appropriate. The heated air may then flow through a duct 20, which may be incorporated into the deployable side wall 21. In the upper portion of the deployable side wall 21, a vent 22 may be provided through which heated air enters the vehicle receiving volume of the enclosure. The air unit comprises an extraction duct 23 located adjacent to the floor of the housing, which causes the air to circulate or flow from upper regions of the vehicle enclosure to the bottom region. Extracted air may then be passed through a number of filters in order to remove contaminants prior to being expelled through a duct or chimney 28. In certain embodiments, the chimney may solely be used for any gaseous emissions produced by the heat exchanger. The heat exchanger 19 may be a direct fired gas burner or any other appropriate kind of heat exchanger. In such embodiments, the heat exchanger may also be equipped with a refrigeration cycle which may be employed to cool the circulated air rather to heat it.
During transportation the module 2 can carry on the roof of its housing both side wall 20 and roof portion 24. In preferred embodiments, side wall 21 is stacked on top of the housing whilst roof portion 24 is itself stacked on side wall portion 21. In preferred embodiments, side wall portion 21 is pivotally secured to an upper portion of the housing in order to be able to change configuration between the stacked configuration of
In a preferred embodiment, the air handling unit may raise the temperature of the incoming air at a temperature which could be as low as −5 degrees Celsius to 22 degrees Celsius to enable a suitable spray temperature to be achieved. The spray temperature is preferably between 15 and 30 degrees Celsius. Similarly, on the bake mode of operation, a temperature in excess of 50 degrees Celsius is envisaged over the entire vehicle containing enclosure to ensure complete curing of 2 pack materials. Preferably, the baking mode operations reaches a temperature between 50 and 75 degrees Celsius. In a preferred embodiment, the temperature reached is of 60 degrees Celsius. These temperatures may also be reached dependent upon the environmental conditions surrounding the enclosure by employing a refrigeration circuit in embodiments where one is provided.
Whilst the primary embodiment shows the combination of two oppositely disposed modules to form the vehicle receiving enclosure, further embodiments envisage a succession of modules of this kind which may be preferably aligned in the longitudinal direction of the enclosures.
Nevertheless, since in preferred embodiments both modules incorporate an air handling unit, the detailed description will be provided with respect to transportable module 102. Transportable module 102 incorporates a housing 104 with a front wall 105 (see
The air handling unit employs a fan 117 (see
During transportation, the module 102 can carry on the roof of its housing both side wall 120 and roof portion 124. In preferred embodiments, side wall 121 is stacked on top of the housing whilst roof portion 124 is itself stacked on side wall portion 21. In preferred embodiments, side wall portion 121 is pivotally secured to an upper portion of the housing in order to be able to change configuration between the stacked configuration of
A number of support beams such as longitudinal beams 129 and 130 may be provided as part of the roof of the module 102. In further embodiments, a plurality of cross beams are also provided such as laterally extending beam 131. These are particularly advantageous in carrying the side wall portion 121 and roof portion 124 as shown in
In a preferred embodiment, the air handling unit may raise the temperature of the incoming air at a temperature which could be as low as −5 degrees Celsius to 22 degrees Celsius to enable a suitable spray temperature to be achieved. The spray temperature is preferably between 15 and 30 degrees Celsius. Similarly, on the bake mode of operation, a temperature in excess of 50 degrees Celsius is envisaged over the entire vehicle containing enclosure to ensure complete curing of 2 pack materials. Preferably, the baking mode operations reaches a temperature between 50 and 75 degrees Celsius. In a preferred embodiment, the temperature reached is of 60 degrees Celsius. These temperatures may also be reached dependent upon the environmental conditions surrounding the enclosure by employing a refrigeration circuit in embodiments where one is provided.
Whilst the primary embodiment shows the combination of two oppositely disposed modules to form the vehicle receiving enclosure, further embodiments envisage a succession of modules of this kind which may be preferably aligned in the longitudinal direction of the enclosures.
In one embodiment, the air handling unit is provided centrally and may be configured to heat either of the adjacent vehicle enclosures. The air handling unit may for example be able to recycle the heated air from a first unit into a second adjacent unit in order to allow more rapid temperature rises suitable for baking paint. For example, in a mode of operation, a vehicle may be prepared, and spray painted at a relatively low or near ambient temperature in a first enclosure. Once spraying is completed the air handling unit may be configured to heat the temperature in said first enclosure to a higher temperature in order to facilitate baking of the paint. In the second adjacent enclosure, a vehicle may be prepared and sprayed at relatively low or ambient temperature and thereafter once the baking has been completed in the first enclosure, a pump may force the heated air from the first enclosure into the second enclosure in order to reach a temperature suitable for baking. By so doing, the first vehicle enclosure may also be replenished with fresh air for the painting of a subsequent vehicle whilst the heated air from the first enclosure may serve as the necessary temperature for heating the second enclosure. The air handling unit may incorporate an exhaust system to draw in from either of the adjacent enclosures as appropriate.
In further embodiments, the air handling module may operate in conjunction with 3 or 4 adjacent vehicle modules and a controller may be provided to cause the flow of air from any of the vehicle enclosure to any other one of the vehicle enclosures.
The junction members may include I- or T- beams, box sections, or plates which are either bolted or welded to the frames of the respective adjacent modules.
During transportation, side walls 209, 210, 211 and 212 rest against a portion of the air handling unit as shown in
A central vehicle enclosure 217 may be formed as the result of the deployment of roof leaf 214 provided a second additional vehicle enclosure 218 is positioned at a sufficient distance from the first vehicle enclosure 213 in order to accommodate the central vehicle enclosure 217.
In other embodiments, one or both of the cooperating vehicle enclosures may primarily be an air handling unit whilst the central vehicle enclosure is the primary vehicle receiving portion of the assembled structure.
In further embodiments, one of the cooperating vehicle enclosures may be provided with the entirety of the leaves which together form the roof of the central vehicle enclosure. These may be stacked during transportation and then deployed as appropriate. The deployment may either require external displacement means such as a crane or other lifting contraption or be facilitated by integral actuators such as hydraulic rams or motors.
Additional junction members may be provided for securing the leaves of the roof together. In certain embodiments, there may be no floor in the central enclosure whilst in other embodiments a floor may also be formed by one or more leaves of the vehicle enclosures. The floor may for example be formed by the combination of two leaves from each one of the side enclosures.
The embodiment of
It also allows the extraction of air to be in the roof of the enclosure whilst still allowing for a particularly compact structure during transportation.
