Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting robots, in particular to an obstacle-clearing mechanism of a fire-fighting robot. Background Art

[0002] A firefighting robot is a robot used to perform firefighting tasks. It can replace humans in dangerous environments to perform tasks such as firefighting, rescue and search. Firefighting robots usually have functions such as autonomous navigation, fire source detection, and fire extinguishing. They can help firefighters work in dangerous environments such as high temperature, thick smoke, and toxic gases, thereby reducing casualties and property losses.

[0003] In complex fire scenes, the robot's obstacle clearing ability is also particularly important to prevent the robot from being unable to pass due to obstacles in front. According to application number 202122373977.6, a fire-fighting robot obstacle clearing mechanism uses a clearing rod to swing obstacles on the moving path of the fire-fighting robot to both sides during use, thereby reducing the impact on the fire-fighting robot's operation. However, the fire scene is complicated, and it is difficult to clear a path for the fire-fighting robot to pass only by swinging the clearing rod left and right. Therefore, an improvement in the obstacle clearing mechanism of the fire-fighting robot is needed to address this problem. Utility Model Content

[0022] The unfolded helix angle of the worm 9 is smaller than the contact friction angle between the worm wheel 7 and the worm 9; thus, the worm wheel 7 and the worm 9 can play a self-locking role; that is, the worm wheel 7 can rotate only when the worm 9 rotates, and the worm wheel 7 and the push plate 4 can be automatically locked and cannot rotate if the worm 9 does not rotate; and the motor 8, worm wheel 7, and worm 9 structure of the device are used to drive the push rod to rotate, which can save complex hydraulic pipelines and control valves compared to the traditional hydraulic cylinder structure, and can also play a basic role of locking the push plate 4; thus, it is convenient for such fire fighting robots to be used;

In this way, the ground clearance of the push plate 4 can be increased when the push plate 4 is not needed, thereby improving the passability of the device; and the worm wheel 7 can only rotate when the worm 9 rotates, and the worm wheel 7 and the push plate 4 can be automatically locked and cannot rotate if the worm 9 does not rotate; and the motor 8, worm wheel 7, and worm 9 structure of the device are used to drive the push rod to rotate. Compared with the traditional hydraulic cylinder structure, the complicated hydraulic pipelines and control valves can be omitted, and the basic function of locking the push plate 4 can also be achieved; thereby, such fire-fighting robots can be easily used.
