[0024] The present invention realizes cable winding and arrangement by providing a movable bearing platform 1, and cooperates with a main reel 3 and an auxiliary reel on the bearing platform 1, thereby reducing the manpower invested in the process of winding, arranging and carrying the cables, realizing automatic winding and carrying, and improving work efficiency.

[0025] In some embodiments, a plurality of lighting devices 9 are provided above the mobile machine room 2, at one end of the carrying platform 1 close to the main reel 3, and at one end of the carrying platform 1 close to the auxiliary reel, to provide lighting for the movement of the carrying platform 1 at night. In some embodiments, a plurality of groups of photovoltaic modules 10 are provided above the mobile machine room 2, and a battery module connected to the photovoltaic module 10 is provided inside the machine room to store the electrical energy generated by the photovoltaic module 10 absorbing solar energy during the day. The battery module is electrically connected to the lighting device 9, and when lighting is needed at night, the battery module supplies power to the lighting device 9.

[0026] In some embodiments, the first driving member 5 includes a variable frequency motor 51 with a self-braking function, and the output end of the variable frequency motor 51 is connected to a first reducer 52, which is fixedly connected to the first bracket 31 and is transmission-connected to the main reel 3. The variable frequency motor 51 can realize intelligent control of the winding speed of the main reel 3, and the output torque and speed of the variable frequency motor 51 are transmitted to the main reel 3 through the first reducer 52, thereby controlling the winding and arrangement operation of the main reel 3.

[0027] In some embodiments, the first reducer 52 is fixedly connected to the first bracket 31 at a position offset from the rotation center of the main reel 3, and the output end of the reducer passes through the first bracket 31 and is connected to the main reel 3 through a gear set. The eccentric setting can prevent the excessive inertia torque of the main reel 3 from affecting the reducer during rotation, and the gear set transmission connection can protect the first reducer 52.

[0028] In some embodiments, a clamping device 8 is provided on the side of the main reel 3 facing the mobile machine room 2. The clamping device 8 includes a stand 81 vertically connected to the carrying platform 1. A connecting frame 82 is hingedly provided on the end of the stand 81 away from the carrying platform 1 and facing the side of the main reel 3. A clamping frame 83 is hingedly provided on the end of the connecting frame 82 facing the main reel 3. A clamping roller 831 is rotatably connected to the end of the clamping frame 83 facing the main reel 3. The clamping roller 831 is arranged parallel to the rotating shaft of the main reel 3. The stand 81 and the connecting frame 82 can make the clamping frame 83 reach the clamping height. At the same time, the clamping roller 831 can roll with the cable to reduce the friction force on the cable and reduce the manpower and material resources required during the cable winding or arrangement process. The length of the clamping roller 831 is set to be the same as the barrel width of the main reel 3, so that the clamping roller 831 can fully clamp the cable on the main reel 3 to avoid the situation where the cable is loose at some positions during the winding process.

[0029] In some embodiments, a hinged rod 821 is provided at the hinged position of the clamping frame 83 and the connecting frame 82. The clamping frame 83 on the side of the hinged rod 821 away from the clamping roller 831 is provided with a first connecting rod parallel to the clamping roller 831. The first connecting rod is provided with an elastic connecting member 833 on the side facing the connecting frame 82. In one embodiment, the elastic connecting member 833 is configured as a spring, and a second connecting rod is provided on the connecting frame 82 directly below the elastic connecting member 833, and the other section of the elastic connecting member 833 is fixedly connected to the second connecting rod. Through the compression of the elastic connecting member 833 by the first connecting rod 832 and the second connecting rod 822, the elastic connecting member 833 will give the first connecting rod 832 an upward force. Through the lever principle, one end of the clamping roller 831 of the clamping frame 83 will be subjected to downward pressure, thereby realizing the downward pressure control of the clamping roller 831. At the same time, since the outermost diameter of the cable will increase as the cable is wound during the winding process, the clamping roller 831 will be lifted up at this time, and the elastic connecting member 833 will give the first connecting rod 832 space to move downward, so that the clamping roller 831 can be lifted up while ensuring that the cable is pressed downward, and the lifted clamping roller 831 can still press the outermost cable.

[0030] In some embodiments, a third connecting rod parallel to the pressing roller 831 is provided on the connecting frame 82, and a telescopic support member 84 is provided between the third connecting rod and the stand 81. In one embodiment, the telescopic support member 84 is configured as a hydraulic cylinder or a pneumatic cylinder, and the telescopic support member 84 is used to control the lifting and lowering of the connecting frame 82. When winding is required, the staff can control the connection frame 82 to descend through the telescopic support member 84, so that the pressing roller 831 on the pressing frame 83 presses the cable in the main reel 3 downward, so that the cable can be tightly wound on the main reel 3 during the winding process.

[0031] In some embodiments, a first automatic cable arrangement device 32 for automatically arranging the main reel 3 is provided at one end of the carrying platform 1 close to the main reel 3. The first automatic cable arrangement device 32 can arrange and route the reeled cables on the main reel 3, thereby reducing the manpower input during manual arrangement and reeling, and improving work efficiency.

[0032] In some embodiments, the second drive assembly includes a stall torque motor 61, the output end of the stall torque motor 61 is connected to a second reducer 62, the output end of the second reducer 62 is fixedly arranged at the rotation center position of the second bracket 41 corresponding to the compensation reel 4, and the output end of the second reduction motor passes through the second bracket 41 and is fixedly connected to the compensation reel 4 to control the rotation of the compensation reel 4. The stall torque motor 61 drives the second reducer 62 to work, thereby driving the compensation reel 4 to rotate, and at the same time, a second bracket for carrying the second drive assembly is arranged on the second bracket 41.

[0033] In some embodiments, a second automatic cable arrangement device 42 is provided at one end of the carrying platform 1 close to the compensation reel 4 to automatically arrange the cables for the compensation reel 4. The second automatic cable arrangement device 42 can arrange and route the cables wound on the compensation reel 4, thereby reducing the manpower input during manual arrangement and winding, and improving work efficiency.

[0034] In some embodiments, the moving assembly mechanism 7 is configured as a crawler traveling assembly. The crawler traveling assembly can improve the passability of the bearing platform 1, and can pass more smoothly on the unpaved ground of the open-pit coal mine.
