Self-Propelled Robot for the Handling of Explosive Charges

Abstract

The invention relates to a self-propelled robot which is used to handle explosive charges and which is of the type that is remote controlled by means of a control console. The inventive robot can be used to handle explosive devices and charges as well as perform special, dangerous operations. According to the invention, the self-propelled robot (1) comprises movement means which are defined by two lateral caterpillar running gears (2) having adjustable running sides, with an adjustable-length scraper (3) being disposed at the rear thereof. The invention also comprises an articulated arm (4) having a first segment (7) which takes the form of a fork that is actuated by a pair of cylinders (6) and which terminates in a clamp (5).

DESCRIPTION OF A PREFERRED EMBODIMENT

With the commented figures in view and in accordance with the numbering adopted, we can see how the self-propelled robot 1 for the handling of explosive devices and charges displays means of displacement defined by two sets of lateral caterpillar running gear 2 driven by conventional means, such as a diesel, gasoline or electric motor, and incorporating a scraper 3 in its front part, along with an articulated arm 4 terminating in a clamp 5.

An important characteristic of the self-propelled robot 1 is that it displays great robustness which permits it to haul and handle heavy loads and likewise, via its running gear, based on a caterpillar track 2, it can displace itself over all kinds of uneven terrain, having great mobility.

Moreover, with the aim of providing the robot 1 with great stability in the handling of heavy loads, the two sets of lateral caterpillar running gear 2 are mounted on a structure which permits separation between both sides by means of operating a simple push-button, in such a way that, when heavy loads have to be handled, the sides of the caterpillar 2 will be separated and the robot 1 will acquire great stability, thus representing a major advantage.

So, the caterpillar sides 2 are mounted by means of a pair of telescopic cross-members 8, in such a way that by means of the respective hydraulic cylinder 9, activated by means of an activation push-button, they will be able to be positioned at different distances from each other.

Also, the scraper 3, actuated by a cylinder 10 in its up and down movement, presents an adjustable length, for which it has individual rotary arms 11 at each end permitting it to adapt its length to that of the running gear, depending on whether it is in its withdrawn or extended position, as can be appreciated in FIGS. 4 and 5 of the designs.

Said rotary arms will be actuated by means of respective cylinders.

Furthermore, the articulated arm 4 mounts the corresponding hydraulic cylinders of the different segments thereof, so that the first segment 7 is actuated by a pair of cylinders 6, for which it incorporates a hydraulic unit, while in order to effect the rotary movements to left and right of the clamp 5 it incorporates an electric motor, in such a way that the articulated movements of the four segments making up the articulated arm 4 are materialised by corresponding actuation cylinders, which have independent action.

In the figures of the designs, the great manoeuvrability of the articulated arm 4 can be seen, and it can be observed how it passes from its extended position (FIG. 1) to a position of being folded on itself (FIG. 2), thereby occupying minimum space.

This is achieved as a consequence of presenting the first segment 7 of the articulated arm in the form of a fork with the clamp 5 being able to pass between its two prongs as it folds (FIG. 2).

Of course, the self-propelled robot 1 incorporates the corresponding control electronics with all incidents appearing on a screen in the control console.

Likewise, the self-propelled robot 1 will incorporate a series of ultrasound distance meters and viewing cameras, permitting all necessary operations to be performed.

Moreover, the clamp 5 can present different characteristics depending on the work to be carried out, and so the clamps can cut, haul, lift and even destroy objects.
