Vehicle-mounted telescopic booms are utilized to provide access to otherwise inaccessible locations, such as elevated surfaces and equipment. The booms can be rotatably mounted to a vehicle to transport the boom to a location and swing the boom about the vehicle base while extending a distal end of the boom from the truck. Booms typically support equipment or a utility platform on the distal end of the boom to allow tools and personnel to perform tasks at the location from an elevated position. For example, a boom can extend and raise a utility platform to support a utility worker and/or equipment and provide access to an overhead electric power line or equipment for maintenance, installation, or the like.
Systems and methods for providing a rotatable boom attachment that is rotatable about at least two different axes with respect to the boom to which the rotatable boom attachment is mounted are described. In an aspect, a system embodiment includes, but is not limited to, a body portion configured to couple to a distal end of a boom, the body portion coupled with a rotational actuator configured to rotate the body portion about a first rotational axis with respect to the boom; a connecting arm rotatably coupled to the body portion; and a motor configured to drive the connecting arm about a second rotational axis having an orientation differing from the first rotational axis, wherein at least one of the body portion or the connecting arm includes a mounting site configured to removably couple to one or more implements.
In an aspect, a system embodiment includes, but is not limited to, a body portion configured to couple to a distal end of a boom, the body portion defining an interior region formed from a top plate coupled with a first side plate and a second side plate opposing the first side plate; a rotational actuator positioned at least partially within the interior region and coupled between the first side plate and the second side plate, the rotational actuator configured to rotate the body portion about a first rotational axis with respect to the boom; a rotational bearing coupled to the top plate; a connecting arm coupled to the rotational bearing; and a motor configured to drive the rotational bearing to rotate the connecting arm about a second rotational axis having an orientation differing from the first rotational axis, wherein at least one of the body portion or the connecting arm includes a mounting site configured to removably couple to one or more implements.

The boom attachment 100 includes one or more mounting sites to detachably couple one or more additional booms, jibs, or mounting structures of equipment, or combinations thereof, to permit the boom attachment 100 to serve as a securing platform for multiple types of equipment in an interchangeable manner with respect to the boom 52. The boom attachment 100 also provides multiple axes of rotation of equipment mounted thereto independent of motion of the boom 52, as described further herein. The boom attachment 100 is shown in
The first mounting site 102 is shown as a mounting plate over which a receiver for equipment, such as a utility platform with a material handling jib and winch (e.g., shown in
The boom attachment 100 includes a body portion 106 that couples to the distal end 50 of the boom 52 (e.g., via bolt or other fastener). The body portion 106 rotates with respect to the boom 52 to provide vertical rotation of the boom attachment 100 with respect to the boom 52. In implementations, the body portion 106 houses or is otherwise coupled to a rotational actuator or other rotational device to rotate the boom attachment 100 in a vertical direction with respect to the boom 52. For example, referring to
In example implementations, the rotational actuator 302 rotates the body portion 106 about a first rotational axis 110 at an angle of about 270 degrees. For example, the body portion 106 can be positioned around the rotational actuator 302 and secured in place through fasteners 111 (e.g., bolts shown in
The body portion 106 includes the first mounting site 102, where positioning of an implement received by or mounted to the first mounting site 102 or to the second mounting site 104 can be controlled through rotation of the body portion 106 (e.g., via activation of the rotational actuator 302), through vertical positioning of the boom 52 and through horizontal rotation of the boom 52 (e.g., about 56 shown in
In implementations, the body portion 106 includes a top plate 112 connected with a first side plate 114 and a second side plate 116 to form an interior region 118 into which the rotational actuator 302 is positioned during rotation of the body portion about the rotational actuator 302. The rotational actuator 302 is shown secured to each of the first side plate 114 and the second side plate 116 via fasteners 111 introduced to apertures 308 at the ends 306 of the rotational actuator 302. The second side plate 116 is shown coupled with an extender 120, which in turn is coupled with a receiver side plate 122. In implementations, the receiver side plate 122 forms an opening for the second mounting site 104 to receive a portion of the equipment to be mounted to the body portion 106 at the second mounting site 104 (e.g., as shown in
The boom attachment 100 also includes a connecting arm 124 rotationally coupled to the body portion 106 with the first mounting site 102 mounted to an end 126 of the connecting arm 124. However, the first mounting site 102 could be positioned along a different portion of the connecting arm 124 to provide differing positions of the second mounting site 102 relative to the boom 52 when the boom attachment 100 is secured to the distal end 50 of the boom 52. The boom attachment 100 is shown with a rotational bearing 128 coupled between the top plate 112 and the connecting arm 124 to rotatably couple the connecting arm 124 to the body portion 106 to provide rotation of the boom attachment 100 relative to the boom 52 about a second rotational axis 138. For example, the connecting arm 124 can be mounted to an upper surface of the rotational bearing 128 and can include a first portion 130 extending outwardly from the body portion 106 (e.g., in a direction away from the boom 52). The connecting arm 124 can also include a second portion 132 extending downwardly from the first portion 130 which then extends outwardly as a third portion 134 coupled with the first mounting site 102. Such configuration can position the first mounting site 102 substantially along the longitudinal midline 58 of the boom 52 when the first mounting site 102 is fully extended from the boom 52 (e.g., through operation of the rotational bearing 128). In implementations, the connecting arm 124 defines one or more apertures 136 to facilitate installation and/or access to the rotational bearing 128, distribution of hydraulic hoses, distribution of electrical wiring, or the like. The second rotational axis 138 is shown as being substantially perpendicular to the first rotational axis 110, however other configurations of the first rotational axis 110 relative to the second rotational axis 138 can be utilized.
The boom attachment 100 includes a motor 140 configured to drive the rotational bearing 128. In implementations, the motor 140 is a hydraulic motor that rotates a gear (e.g., a worm gear) in contact with teeth of the rotational bearing 128 to provide rotation of the rotational bearing 128 and the coupled connecting arm 124 about the second rotational axis 138. Hydraulic fluids can be made available to the motor 140 via the hydraulic valves 60 supported by the boom 52. In example implementations, activation of the rotational bearing 128 causes rotation of the connecting arm 124 about the second rotational axis 138 at an angle of about 180 degrees. For example,
The boom attachment 100 provides multiple options for positioning equipment mounted to either of the first mounting site 102 or the second mounting site 104. For instance, each of the first mounting site 102 and the second mounting site 104 can be positioned through vertical, horizontal (e.g., about 56 shown in
In implementations, the boom attachment 100 includes leveling structures to provide self-leveling of equipment secured to the body portion 106 via the mounting sites (e.g., the first mounting site 102, the second mounting site 104, etc.). For instance, the boom attachment 100 can include a control system coupled to or included in one or more of the rotational actuator 302, the controller 310, the hydraulic valves 60, a hydraulic fluid controller, the drive for the rotational bearing 128 (e.g., motor 140), or combinations thereof to rotate the body portion 106 or the connecting arm 124 to provide a level platform for the mounting sites. In an implementation, the control system includes one or more level sensors in communication with one or more hydraulic valves to control actuation of the rotational actuator 302 based on output of the level sensor. The level sensor can include, but is not limited to, a digital inclinometer.
In implementations, the connecting arm 124 includes a material handling winch 142 to facilitate transfer of supplies to a utility platform coupled to the first mounting site 102 or the second mounting site 104. For example, the material handling winch 142 can include a motor (e.g., hydraulic motor, electric motor, other motor, etc.) to turn the winch to spool a cable supported by a material handling jib (e.g., jib 800 coupled to a utility platform 802 shown in
The boom attachment 100 can facilitate application of a main boom winch load line. For example, referring to
The boom 52 can be configured to facilitate tool usage with equipment mounted to the mounting sites of the boom attachment 100 or to provide personnel working on or in utility platforms secured to the mounting sites. For example, the boom 52 can include a tool connection portion 146 positioned at the distal end 50 of the boom. The tool connection portion 146 can include, for example a hydraulic tool circuit connector, to supply hydraulic power to one or more tools supported by the boom attachment 100. For example, personnel working on a utility platform supported by one or more of the first mounting site 102 or the second mounting site 104 can utilize tools powered at least in part through the hydraulic power supplied by fluid lines coupled with the hydraulic tool circuit connector. Such tools can include, but are not limited to, crimpers, saws, and the like. In implementations, the hydraulic tool circuit connector is fluidically coupled with the hydraulic valves 60 to provide hydraulic power to the hydraulic tool circuit connector which in turn can transfer to the tools via fluid connection hoses or the like.
In implementations, the boom 52 includes a hydraulic generator 148 disposed at the distal end of the boom 52. The hydraulic generator 148 is configured to convert hydraulic forces to electric power to supply to various portions of the boom attachment 100. For example, the electric power can be utilized by personnel working on a utility platform supported by one or more of the first mounting site 102 or the second mounting site 104, control systems of the boom attachment 100 (e.g., solenoids of the self-leveling structures), or by other individuals or systems. The hydraulic generator 148 can be fluidically coupled with the hydraulic valves 60 to provide hydraulic fluid to the hydraulic generator 148 which in turn converts the hydraulic fluid forces to electric power. The hydraulic generator 148 can avoid running substantial gauges or amounts of electrical wiring along the boom 52 to the boom attachment 100.
