Description

Technical Field

[0001] The utility model relates to the technical field of bomb disposal, in particular to an unmanned search and disposal vehicle. Background Art

[0002] In the hazardous source working environment, there may be dangerous objects or explosives, which need to be eliminated. Existing bomb disposal devices generally use search and disposal vehicles, such as the mechanical arm, bomb disposal vehicle and search method disclosed in the existing patent publication number CN109664321A, which adopts the first clamping arm and the second clamping arm to be pivotally connected to the mounting seat respectively, and the first clamping arm and the second clamping arm are linked; the first torsion member is connected to the mounting seat and is used to drive the second clamping arm so that the first clamping arm and the second clamping arm swing in opposite directions around their respective pivot axes, and the first clamping arm and the second clamping arm ensure synchronous movement through gear meshing transmission, thereby achieving stable clamping. However, it has the following problems: (1) It uses an ordinary mobile crawler chassis with poor off-road performance; (2) It uses a homemade mechanical arm with poor flexibility and stability; (3) The gear meshing gripping method does not have enough gripping force.

[0003] Another example is the visualized search and bomb disposal collaborative processing device disclosed in the existing patent publication number CN114390253A. It improves the passability during movement by setting five running wheels in each group of driving components, and the lifting and lowering of the running wheels do not interfere with each other. The driving gear and the limit gear ensure good driving ability when the running wheels are lifted and lowered, which is convenient for passing through uneven areas and reducing the shaking amplitude of the bomb disposal device. The two mechanical arms facilitate collaborative operation, facilitate the clearing of obstacles and the removal of explosives, and the pneumatic lifting component facilitates the adjustment of the height of the video acquisition component, thereby improving the video acquisition effect and the visualization effect. The protective cover and the protective ring facilitate the protection of the camera during the explosion to avoid the loss of video data. It has better walking ability, but its mechanical arm is set on the front side end face of the chassis, so that the operating range of the mechanical arm is limited to the front side of the chassis. If the operating direction is to be changed, the chassis needs to be rotated by a certain angle, which is inconvenient to operate. Utility Model Content

The crawler chassis 1 has an A side and a B side arranged opposite to each other. A support 2 is vertically provided on the A side of the crawler chassis 1. A second camera 7 and a radar 5 are provided on the outer surface of the B side of the crawler chassis 1. A multi-axis mechanical arm 3 is provided at the upper end of the crawler chassis 1 near the B side. A clamp 4 and a first camera 6 are provided at the end of the mechanical arm 3.

[0024] First, the industrial computer plans the path of the target point position and the map, and then controls the crawler chassis 1 to move to the position. The first camera 6 obtains the image captured by the mechanical arm 3, and the second camera 7 obtains the image of the crawler chassis 1 when it moves. The pan-tilt 8 has a shooting device that can obtain the impact of the surrounding environment of the unmanned search and sorting vehicle. The pan-tilt 8, the first camera 6 and the second camera 7 can provide the operator with a multi-angle field of view.

[0025] The first support rod 9, the second support rod 10, the driving member 11 and the auxiliary wheel 12 are arranged on the B side of the crawler chassis 1. One end of the first support rod 9 and the second support rod 10 are both hinged to the crawler chassis 1, the driving member 11 is hinged between the crawler chassis 1 and the second support rod 10, the auxiliary wheel 12 is rotatably arranged on the first support rod 9, and the driving member 11 is telescopic to drive the second support rod 10 to unfold or fold to drive the first support rod 9 to be lowered or raised.
