It is the command center of the fully mechanized coal mining face in coal mines, where switches for controlling large equipment such as working chutes, conveyors, crushers, etc., large equipment such as mobile substations, emulsion pumps, and pump boxes are installed. The equipment train will move as the mining progresses.

[0003] According to the large-slope gate roadway self-moving equipment train proposed in Chinese Patent No. 201510178701.9, this utility model highly integrates functions such as train self-movement, walking deviation adjustment, and pipe and cable self-movement, and can self-move in the gate roadway with a slope of ±25°, effectively preventing equipment from slipping and ensuring safe operation in the roadway with a large slope.

[0004] According to a mine roadway slide rail motor vehicle proposed in Chinese Patent No. 202110332340.4, a front-end slide rail deviation adjustment and guiding device can effectively control the deviation phenomenon generated during the advancement of the slide rail. The special trough-shaped track closely cooperates with the train support pulleys, having small friction and preventing the train from derailing and falling off the track. The train walking support pulley group can both walk and hang the slide rail. When the train moves, it supports the entire vertical vehicle to walk. When advancing the slide rail forward, it can hang the slide rail off the ground, and then the power device advances the slide rail forward.

[0005] Combined with the above patent content and the prior art, the currently used mine equipment trains are all developing in the direction of self-moving in steps and advancing along the slide rail. During the cable laying and cleaning process of such mine equipment trains, the floor-mounted cable brackets are dragged by the train to lay the cables. With the development of technology, suspended cable brackets will also be used in tunnels to leave more space in the mine. However, the current mine equipment trains dragging the brackets result in a long train length and a large load. Installing cables with suspended cable brackets is also very inconvenient, involving too much manpower and having very low efficiency, and the cables are intricate and messy.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0033] Please refer to Figures 1 to 6, in the embodiment of the present utility model, a self - moving train for coal mine cables includes a control host, a pulling device 1 and a flatbed truck 2. A track moving component 3 and a lifting support moving component are arranged at the bottom of the flatbed truck 2. A cable reel group 8 and a driving component group 7 for driving the cable reel group 8 to rotate are arranged at the top of the flatbed truck 2. A rocker arm component for retracting the cable is also assembled at the head of the flatbed truck 2. A fence 12 is arranged at the top of the flatbed truck 2, and a hanging cable support can be stored inside the fence 12. During the movement of the train, it is manually fixed on the side wall of the tunnel. An on - vehicle wire rack 13 is also arranged inside the flatbed truck 2 to prevent the cable from dragging on the ground;

[0034] The cable reel group 8 is composed of multiple groups of cable reels. Each group of cable reels includes two brackets 801, a wire 802, a rotating connecting piece 803, a rotating bearing 804, a cable reel 805, a driven gear 806 and a brush ring 808. The two brackets 801 are fixed on the top of the flatbed truck 2. One of the brackets 801 installs a rotatable cable reel 805 through the rotating connecting piece 803 and the rotating bearing 804. A brush ring 808 is assembled inside the cable reel 805. The conductive terminals of the brush ring 808 are hidden and connected to the outside through the wire 802 from inside the bracket 801. The brush ring 808 is a high - voltage slip ring, which realizes continuous power transmission between the rotating equipment and the fixed equipment, while maintaining the coherence of rotation and the reliability of the machine. The power - in terminal of the brush ring 808 is connected to the cable wound outside the cable reel 805, and the conductive terminals are hidden and connected to the outside through the wire 802 from inside the bracket 801. The outer rotor of the brush ring 808 rotates, and the inner stator is fixed. During the rotation of the cable reel 805, the cable is wound and unwound. The conductive terminals led out from the stator are charged and used for equipment or power transmission. The method of winding and unwinding the cable by the cable reel group 8 can better save space and use fewer flatbed trucks 2 to build and load the cable configuration requirements for a longer distance;

[0035] The driving component group 7 includes a driving motor 701, a fixing frame 703, a transmission shaft 708 and a driving wheel 704. The output end of the driving motor 701 installs the transmission shaft 708. The transmission shaft 708 is rotatably connected to the flatbed truck 2 through the fixing frame 703. A driving wheel 704 meshing with the driven gear 806 is installed outside the transmission shaft 708. The driving component group 7 is the main driving component for winding and unwinding the cable reel group 8. Because the cable reel group 8 is large in volume and strong in resistance, and there is a brush ring 808 at its center, an external transmission method is adopted. The driven gear 806 of the cable reel 805 is driven by the driving wheel 704. Its gear ratio can be suspended according to the actual situation, and generally not less than driven gear 806:driving wheel 704 = 5:1. This can not only solve the problem of the installation of the driving position, but also increase the torque and provide a more stable output;

[0036] The rocker arm component includes two swing arms 14, a swing oil cylinder 9 and a roller shaft 10. Both swing arms 14 are rotatably connected to the flatbed truck 2. A swing oil cylinder 9 capable of adjusting the height of the swing arm 14 is provided on the swing arm 14. The other end of the swing oil cylinder 9 is connected to the column on the flatbed truck 2. The swing oil cylinder 9 is rotatably connected to the swing arm 14 and the flatbed truck 2 through rotating components. The rocker arm component can lift the cable. The rocker arm component can also be provided on the front and rear sides of the flatbed truck 2 respectively. It mainly has two functions. The first function is that when the distance between the flatbed trucks 2 is large, the rocker arm component can lift the cable to prevent the cable from dragging and wearing. The second function is that during the installation of the cable support, the rocker arm component can lift the cable, saving the labor intensity of workers and providing great convenience during the process of manually installing and assembling the cable onto the cable support.

[0037] In a preferred embodiment, the track moving component 3 includes a railway track and a hydraulic cylinder, and the lifting support foot moving component includes a hydraulic cylinder and a support foot component. A wheel set capable of rolling on the railway track is provided at the bottom of the flatbed truck 2. The hydraulic cylinder drives the support foot component to support and lift the flatbed truck 2 off the ground. The hydraulic cylinder of the track moving component 3 drags the railway track forward. The hydraulic cylinder drives the support foot component to support and make the wheel set of the flatbed truck 2 land on the railway track. In this application, a creeping method is adopted, and the flatbed truck 2 moves forward one by one in a creeping manner. During the movement, the single flatbed truck 2 needs to be dragged. Cooperating with the bottom track moving component 3 and the lifting support foot moving component, the dragging driving load used is reduced, the moving safety factor is high, the equipment runs more stably, and there will be no slipping, self-sliding movement and runaway situations.

[0038] In a preferred embodiment, two adjacent flatbed trucks 2 are connected by a dragging component;

[0039] The dragging component includes a dragging oil cylinder 4, a balance frame 5 and a coupler device 6. Dragging oil cylinders 4 are evenly distributed between the two flatbed trucks 2. The other ends of the dragging oil cylinders 4 are all fixed to the balance frame 5. The balance frame 5 is connected to the adjacent flatbed truck 2 through the coupler device 6 for mutual traction. The coupler device 6 is a prior art and is usually used for connecting railway carriages. The same connection method is adopted in this application. When the cable laying of the flatbed truck 2 is completed, the coupler device 6 of this flatbed truck 2 is disconnected, so that this section of the flatbed truck 2 stays in place, or it can be dragged empty after wiring with a connector, reducing the dragging weight and power consumption.

[0040] In a preferred embodiment, during the movement of the flatbed truck 2 to the right by the dragging component, the lifting support foot moving component of the adjacent flatbed truck 2 on the left is in a support braking state. The oil inlet pipeline of the dragging oil cylinder 4 of the dragging component between the adjacent flatbed truck 2 on the left and the moving flatbed truck 2 is opened. During the movement of the front vehicle, the dragging oil cylinder 4 of the adjacent flatbed truck 2 on the left is stretched, hydraulic oil enters, and at the same time, the swing oil cylinder 9 extends. Below the swing arm 14, the length of the connecting cable meets the change in the distance between adjacent flatbed trucks 2. In the peristaltic movement mode, the technical difficulty lies in that the connection distance of the cable is fixed, while the distance between flatbed trucks 2 changes during the peristaltic movement, resulting in the cable being broken or stretched. Therefore, the rocker arm component can also play a role in pre-tensioning it, preventing the cable from dragging on the ground and avoiding the cable from being broken, adapting to the change in the distance between flatbed trucks 2 during the peristaltic movement.

[0041] In a preferred embodiment, a coupling 707 and a reducer 702 are also installed between the drive motor 701 and the transmission shaft 708. A clutch 706 is provided on the transmission shaft 708 between two adjacent driving wheels 704. The coupling 707 plays a role in protecting the motor from overload. The reducer 702 can be a cycloidal pinwheel reducer. The cycloidal pinwheel reducer is an efficient, compact and reliable mechanical transmission device with the advantages of high transmission efficiency, high precision, large reduction ratio and low noise and compact structure. Whether for control or transmission, it is a very suitable choice for the winding and unwinding of the cable reel group 8. Some of the cables of the cable reel group 8 may be spare or selected, and need to be selectively rotated during driving. The clutch 706 can play a role in selective transmission, and the clutch 706 can be an electromagnetic clutch.

[0042] In a preferred embodiment, the cable reel group 8 is also provided with an internal high-voltage cable connector 807 and an external high-voltage cable connector 809. The cable wound around the outside of the cable reel group 8 has one end connected to the internal high-voltage cable connector 807 and the other end connected to the external high-voltage cable connector 809 installed on the adjacent flatbed truck 2.

[0043] In a preferred embodiment, the flatbed truck 2 is equipped with a cable clamp 705. The cable clamp 705 connects the end of the cable of the flatbed truck 2 of the front vehicle. During the dragging process of the cable, it may affect the connection stability of the high-voltage cable connector. Therefore, it is fixed by the cable clamp 705 to avoid the direct force of dragging on the high-voltage cable connector.

[0044] In a preferred embodiment, a cable tractor 11 is provided on the flatbed truck 2. The cable wound around the outside of the cable reel group 8 passes through the cable tractor 11. The cable tractor 11 conducts the traction for winding and unwinding the cable. The cable tractor 11 is mainly used during the winding process or for tightening the cable tension.

[0045] In a preferred embodiment, wheel speed sensors are provided on the wheel sets at the bottom of the flatbed truck 2. The control host controls the cable operation of the corresponding drive component group 7 and the rocker arm component and the movement of the flatbed truck 2 based on the moving distance detected by the wheel speed sensors. The drive component group 7 controls the cable payout length or cable retraction length based on the movement data collected by the wheel speed sensors.

[0046] Regarding the cable reel 805, the more turns of the wound cable, the larger the diameter will be, and the length of the cable wound in one turn will also become longer. It can be calculated using the regular formula for tying a cylinder with a rope.

[0047] Length of one turn of n-layer cable winding = 2π (radius of the cable reel 805 + radius of the cable × (n - 1));

[0048] Length of n-layer cable winding = 2π (radius of the cable reel 805 + radius of the cable × (n - 1)) × number of turns;

[0049] Length of n-layer cable = length of 1-layer cable winding + length of 2-layer cable winding + length of 3-layer cable winding... + length of (n - 1)-layer cable winding;

[0050] n represents the number of winding layers of the cable;

[0051] The number of turns of the cable wound in each layer is set according to the width of the cable reel 805.

[0052] Calculation can improve the accuracy of calculating the length of the cable wound on the cable reel 805.

[0053] It is also possible to install wheel speed sensors on the cable tractor 11 and control the cable payout and retraction length of the cable reel 805 based on the traction distance collected by the wheel speed sensors. It is also possible to calculate the cable payout and retraction length through both calculation methods simultaneously to avoid cable calculation errors caused by the cable sliding inside the cable tractor 11, and the two can be calibrated and corrected.

[0054] It should be noted that the above embodiments all belong to the same inventive concept of the utility model. The descriptions of the embodiments have their own focuses. For the parts not described in detail in individual embodiments, reference can be made to the descriptions in other embodiments.

[0055] The above-described embodiments only represent the implementation manners of the present utility model. The descriptions are relatively specific and detailed, but should not be construed as limiting the scope of the utility model patent. It should be pointed out that for those of ordinary skill in the art, without departing from the inventive concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims..
