[0005] Furthermore, the front track assembly includes a front rotating arm and a front drive wheel assembly, wherein the front rotating arm is connected to a front rotating shaft and is mounted on one side of the front drive wheel assembly.

[0006] Furthermore, the rear track assembly includes a rear rotating arm and a rear drive wheel assembly, wherein the rear rotating arm is connected to a rear rotating shaft and is mounted on one side of the rear drive wheel assembly.

[0007] Through the above technical solution, the chassis drive assembly, the front track assembly, and the rear track assembly can each operate independently, and the rotation mode of the front track assembly and the overall weight after rotation and lifting are supported by the two front rotating arms.

[0008] Furthermore, the front track assembly and the rear track assembly can rotate around the chassis drive assembly at an angle between ±30 degrees, which allows the device to achieve climbing functionality.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] An embodiment of this utility model of coal mine disaster rescue equipment, such as... Figure 1-3 The device includes a chassis drive assembly 100, a front track assembly 200, a rear track assembly 210, a control box 300, and a robotic arm 5. The chassis drive assembly 100 houses the powertrain of the device, which is electrically driven. A side plate 110 mounted on the chassis drive assembly 100 bears the weight of the front track assembly 200 and the rear track assembly 210 after rotation and lifting. Four guide wheels 120 fixed to the side plate 110 are added to ensure normal operation of the device after one end is subjected to force. Powertrains are installed on both the front track assembly 200 and the rear track assembly 210, which are electrically driven. 11a drives the front driven wheel 212a to operate autonomously, and the rear drive wheel assembly 211b drives the rear driven wheel 212b to operate autonomously. During the movement, when the front track assembly 200 encounters potholes, the front rotating shaft 130a rotates, causing the front rotating arm 140a to rotate, so that the entire front track assembly 200 and the chassis drive assembly 100 form a 30-degree angle, allowing for quick passage. During the reversing process, the rear track assembly 210 can also rotate through the rear rotating shaft 130b, causing the rear rotating arm 140b to rotate, so that the entire rear track assembly 210 and the chassis drive assembly 100 form a certain angle, which can effectively improve the efficiency of traveling.

[0016] like Figure 2As shown, the robotic arm 5 includes a first rotating assembly 500, a second rotating assembly 510, a large arm 511, a third rotating assembly 520, a forearm 521, an electric telescopic assembly 530, a wrist joint assembly 600, and a mechanical gripper 700 assembly. The first rotating assembly 500 is installed inside the control box 300. One end of the second rotating assembly 510 is connected to the first rotating assembly 500, and the other end is connected to the large arm 511. The third rotating assembly 520 is installed between the large arm 511 and the forearm 521. The electric telescopic assembly 530 is installed inside the forearm 521. The wrist joint assembly 600 is installed at one end of the electric telescopic assembly 530 and is connected to the mechanical gripper 700. The mechanical gripper 700, driven by the gripper body 710, uses the rotating linkage joint 720 to open and close, and uses the clamping blocks 730 on both sides to clamp obstacles for cleaning. During the process of clearing obstacles, the mechanical gripper 700 can effectively shorten the time for clearing obstacles under complex working conditions due to the degree of freedom and sensitivity of its robotic arm 5.

[0017] When the coal mine disaster rescue equipment is remotely controlled, the detection component 400 set on its control box 300 mainly detects the temperature and gas concentration. The detected signals are transmitted to the control console through cables. Since the chassis drive component 100, the front track component 200, the rear track component 210 and the robotic arm 5 are powered by electricity, the cables are connected to the control box 300 through the cable interface 410.

[0018] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
