Description

Technical Field

[0001] This utility model relates to the field of cable equipment, and in particular to a cable winding device for underground coal mine operations. Background Technology

[0002] A cable is a device consisting of several or groups of conductors used to transmit electrical energy or signals. It is widely used in various construction sites for temporary power supply. Underground mines have limited working space, harsh working environments, and variable operating conditions, requiring frequent adjustments to cable layout and thus frequent cable winding and unwinding. Existing cable winding devices have fixed structures and stable winding and unwinding speeds, making it impossible to adjust the speed according to actual conditions, which is inconvenient for underground coal mine operations. Utility Model Content

[0003] The purpose of this invention is to provide a cable winding device for underground coal mine operations. This device can adjust the winding and unwinding speed of the cable by adjusting the diameter of the outer shaft and changing the length of the cable wound around the outer shaft, thus adapting to the needs of different working conditions.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a cable winding device for underground coal mine operations, comprising a mounting frame and a winding mechanism. The winding mechanism includes an inner rotating shaft and an outer rotating shaft. A threaded rod is threadedly connected to the center of the inner rotating shaft. Several adjusting plates are evenly arranged on the threaded rod. The outer surface of the adjusting plates is inclined. The outer rotating shaft is surrounded by multiple arc-shaped plates. A sliding plate is fixedly connected to the inner side of the arc-shaped plates. The sliding plate passes through the inner rotating shaft and cooperates with the adjusting plates. Both ends of the inner rotating shaft are rotatably connected to the mounting frame. A reduction motor is provided on one side of the mounting frame. The reduction motor is connected to one end of the inner rotating shaft through a gear. One end of the threaded rod passes through the mounting frame and is provided with a handwheel.

[0005] Optionally, the bottom of the sliding plate is provided with a slope that matches the adjustment plate.

[0006] Optionally, a limit plate is provided at the bottom of the sliding plate.

[0007] Optionally, baffles are provided on both sides of the winding mechanism.

[0008] Optionally, a lock nut is provided on the threaded rod.

[0009] Optionally, the outer side of the curved plate is provided with anti-slip protrusions.

[0010] Optionally, the mounting bracket is equipped with wheels at the bottom.

[0011] The cable winding device for underground coal mine operations of this utility model has the following advantages:

[0012] (1) By rotating the threaded rod, the diameter of the outer shaft can be adjusted, thereby changing the length of the cable wound in one rotation of the outer shaft, thus adjusting the cable winding speed. It is suitable for different working conditions and is flexible in use.

[0013] (2) The inclined surface of the sliding plate and the inclined surface of the adjusting plate cooperate to make the sliding plate expand outward more easily and reduce the difficulty of operating the threaded rod; the limiting plate can prevent the outer rotating shaft from falling off the inner rotating shaft.

[0014] (3) The locking nut can fix the position of the threaded rod and prevent the outer shaft diameter from suddenly becoming smaller, causing the cable to loosen and fall off. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] like Figures 1-4 As shown, a cable winding device for underground coal mine operations includes a mounting frame 1 and a winding mechanism 2. The mounting frame 1 is equipped with wheels 3 at its bottom for easy movement of the device. Baffles 4 are provided on both sides of the winding mechanism 2 to prevent the cable from falling off. The winding mechanism 2 includes an inner shaft 5 and an outer shaft 6. A threaded rod 7 is threaded to the center of the inner shaft 5, and several adjusting plates 8 are evenly arranged on the threaded rod 7. The outer surface of the adjusting plates 8 is inclined. The outer shaft 6 is surrounded by multiple arc-shaped plates 9. Anti-slip protrusions 10 are provided on the outer side of the arc-shaped plates 9. The anti-slip protrusions 10 can increase the friction between the arc-shaped plates 9 and the cable, preventing the cable from loosening during winding. A sliding plate 11 is fixedly connected to the inner side of the arc-shaped plate 9. The sliding plate 11 passes through the inner rotating shaft 5 and cooperates with the adjusting plate 8. The bottom of the sliding plate 11 is provided with an inclined surface that matches the adjusting plate 8. The inclined surface of the sliding plate 11 cooperates with the inclined surface of the adjusting plate 8, which allows the sliding plate 11 to expand outward more easily and reduces the operating difficulty of the threaded rod 7. A limiting plate 12 is provided at the bottom of the sliding plate 11. The limiting plate 12 can limit the sliding distance of the sliding plate 11 and prevent the outer rotating shaft 6 from falling off the inner rotating shaft 5.

[0021] The two ends of the inner rotating shaft 5 are rotatably connected to the mounting bracket 1. A geared motor 13 is provided on one side of the mounting bracket 1. The geared motor 13 is connected to one end of the inner rotating shaft 5 through gears, and the geared motor 13 can drive the inner rotating shaft 5 and the outer rotating shaft 6 to rotate. One end of the threaded rod 7 passes through the mounting bracket 1 and is provided with a handwheel 14. A locking nut 15 is provided on the threaded rod 7 near the outer side of the mounting bracket 1. When it is necessary to adjust the position of the threaded rod 7, the locking nut 15 is loosened; when it is necessary to fix the position of the threaded rod 7, the locking nut 15 is tightened.

[0022] When the handwheel 14 is rotated to move the threaded rod 7 to the left, the adjusting plate 8 will press the sliding plate 11 outward, causing the outer shaft 6 to open outward. The diameter of the outer shaft 6 increases, and the length of the cable wound in one rotation increases, which can improve the speed of cable winding and unwinding. When the handwheel 14 is rotated to move the threaded rod 7 to the right, the sliding plate 11 will fall naturally, causing the outer shaft 6 to retract outward. The diameter of the outer shaft 6 decreases, and the number of layers of cable wound increases, which can improve the length of cable wound by the device and improve the flexibility of the device, making it suitable for the changing working conditions underground.

[0023] The embodiments described above are merely some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the protection scope of this utility model.
