[0039] Second Embodiment

[0040] Please refer to Figure 4 、 Figure 5 、 Figure 6 , Figure 4 which is a schematic structural diagram of the second embodiment of the fire-fighting robot provided by the present invention; Figure 5 is Figure 4 an enlarged view of the area A shown in Figure 6 Based on the fire-fighting robot provided in the first embodiment of the present application, the second embodiment of the present application proposes another fire-fighting robot. The second embodiment is only a preferred way of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0041] Specifically, the difference of the fire-fighting robot provided in the second embodiment of the present application is that an installation opening 15 is provided on one side of the mounting bracket 1, and movable brackets 34 are rotatably connected to the front and back of the inner wall of the installation opening 15. The movable brackets 34 are two square metal plates.

[0042] A connecting rod 39 is fixedly connected to the middle position between the two movable brackets 34. A rotating buckle 32 is fixedly connected to the top of the connecting rod 39. The top of the rotating buckle 32 is rotatably connected to a cylinder 33, and the other end of the cylinder 33 is rotatably connected to the other side of the installation box 6 through the rotating buckle 32.

[0043] The other ends of the movable frames 34 are rotatably connected with contact plates 37. Fixed blocks 35 are fixedly connected to the opposite sides of the movable frames 34. The contact plates 37 are in contact with the ground. The other ends of the movable frames 34 have bevels, and the contact plates 37 are rotatably connected to the bevels.

[0044] Hydraulic rods 38 are fixedly connected to the bottoms of the fixed blocks 35. Support wheels 36 are fixedly connected to one ends of the hydraulic rods 38. The support wheels 36 play a supporting role when the fire-fighting robot loses its balance. The mounting frame 1, the drive gear 2, the crawler 3 and the mounting box 6 form the base of a fire-fighting robot, and the rest of the equipment is mounted on the base.

[0045] Compared with the related art, the fire-fighting robot provided by the present invention has the following beneficial effects:

[0046] When it is necessary to use the fire-fighting robot to spray water at the fire scene, the cylinder 33 drives the movable frame 34 to move downward at the position of the mounting opening 15 to bring the contact plate 37 into contact with the ground, so as to offset the reaction force of the water when the fire-fighting robot sprays water. If the fire-fighting robot loses its balance at the fire scene, only need to start the hydraulic rod 38 on the movable frame 34 to make the support wheel 36 on the inclined side contact the ground, which plays a role in supporting and balancing the fire-fighting robot, and can effectively reduce the possibility of the fire-fighting robot losing its balance and toppling at the fire scene.
