Description

Technical Field

[0001] This invention relates to the field of coal mine cable winding technology, specifically a cable winding device for fully mechanized coal mining faces. Background Technology

[0002] Both the movement and cutting of coal mining machines require electrical energy. The power supply to the coal mining machine is usually provided by a mobile substation via cable. The cable is laid from the mobile substation to the coal mining machine using cable clamps connected by pins or bolts to form a protective cable chain. This cable chain can rotate flexibly at a certain angle as the coal mining machine's working face moves. The inner steel strip skeleton is directly used to connect adjacent cable clamps, bearing the drag force of the moving coal mining machine's working face. Some cables require length control by a winding device during use, and the cable is prone to slippage when used in the groove of the cable clamp. Furthermore, the cable needs to move within the cable clamp during winding, and the uncertainty of the cable's position is easily affected by wear from gangue and coal blocks in the groove, making the cable relatively unstable during winding. Therefore, a cable winding device for fully mechanized coal mining faces is needed. Summary of the Invention

[0003] The purpose of this invention is to provide a cable winding device for fully mechanized coal mining faces. By restricting the movement of the cable during its use and stabilizing its position, the cable is protected during use and winding, effectively solving the problems in the prior art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A cable winding device for a fully mechanized coal mining face includes a winding frame and a fully mechanized mining area. The winding frame is located within the fully mechanized mining area. A winding roller is rotatably connected inside the winding frame. Several cable clamps are provided on the outer side of the winding frame. The cable clamps are hinged together by an inner steel frame. The inner steel frame has a cable dragging groove for placing the cable. Several anti-slip protection components are provided on both sides of the cable clamps. The anti-slip protection components include a fixed base, a rotating stud, an attachment connecting plate, and a resistance contact pad. A main pull rope is provided on the outer side of the winding frame. Each winding frame is provided with a resistance contact pad. The outer end face of the resistance contact pad contacts the outer wall of the cable to increase resistance. The resistance contact pad drives the rotating stud to rotate. The resistance contact pad slides within the attachment connecting plate to release resistance while winding the cable.

[0006] As a further embodiment of the present invention: the fixing seat is fixed to the outside of the cable clamp, and a sliding rack is slidably connected inside the fixing seat. One end of the main pulling rope is fixed to the outermost sliding rack; pulling the outer sliding rack moves the sliding rack so that the sliding rack can move inside the fixing seat.

[0007] As a further embodiment of the present invention: a gear box is provided above the sliding rack, and a gear is rotatably connected inside the gear box. The gear meshes with the sliding rack, and the gear is fixed to the outer wall of the rotating stud. When the sliding rack moves, it can drive the gear inside the gear box to rotate under the meshing action, thereby causing the rotating stud to rotate.

[0008] As a further embodiment of the present invention: the rotating stud is threadedly connected to the cable clamp, and one end of the rotating stud is rotatably connected to the resistance contact pad, the resistance contact pad being made of rubber; the rotating stud and the cable clamp are threadedly connected, and under the action of the thread, the rotating stud can retract, and there is a movable space on the rotating stud, which will not affect the position of the gear. The rotating stud moves the resistance contact pad into the attachment connecting plate and moves away from the cable, thereby releasing the resistance and winding the cable.

[0009] As a further embodiment of the present invention: the attachment connecting plate is fixedly connected to the inner steel frame, and both sides of the attachment connecting plate are fixedly connected with extended protection plates for limiting the position of the cable; the position of the extended protection plates can further limit the cable position, and the arc-shaped extended protection plates can increase the protection area of ​​the cable, reduce the impact of gangue or coal on the cable, and at the same time provide a certain protection for the resistance contact pad.

[0010] As a further embodiment of the present invention: the main pulling rope has several connecting synchronous ropes, and several sliding racks are connected by the connecting synchronous ropes, which are elastic bands; the main pulling rope has several connecting synchronous ropes, and several sliding racks are connected by the connecting synchronous ropes, which are elastic bands. The connecting synchronous ropes have a certain elasticity during use, which facilitates the repositioning of multiple sliding racks. The elasticity can also be spring-type, so that the sliding racks and the fixed base can be connected by springs. A lifting ring can be set on the sliding rack, so that the main pulling rope can be connected to the lifting ring. At the same time, the connecting synchronous rope can be wrapped around the lifting ring and fixed to the next lifting ring. Thus, the connecting synchronous rope, under the action of the main pulling rope, can drive the remaining sliding racks to move.

[0011] As a further embodiment of the present invention: a control component is provided on the outside of the winding frame. The control component includes an outer frame, a rotating shaft and a drive disk. The rotating shaft is rotatably connected inside the outer frame, and the outer frame is fixedly connected to the winding frame. The position of the resistance contact pad can be controlled by the control component, so that the position of the resistance contact pad can be changed according to the working requirements.

[0012] As a further embodiment of the present invention: a drive disc for controlling the rotation of the rotating shaft is provided on the outer side of the external frame, and one end of the main pull rope is fixed to the outer wall of the rotating shaft; the rotating shaft is driven to rotate, and when the rotating shaft rotates, the rotating shaft can wind the main pull rope, thereby causing the main pull rope to pull the sliding rack to move.

[0013] As a further aspect of the present invention, a cable winding device for a fully mechanized coal mining face includes the following usage methods:

[0014] A: When the cable is in use, the resistance contact pad is located in the cable chute. The resistance contact pad provides a certain resistance to the cable and can limit the movement of the cable during use. At the same time, the position of the extension protection plate can further limit the movement.

[0015] B: When the cable is not in use, the take-up roller can be controlled to take up the cable, and the rotating shaft can be driven to rotate. The main pull rope and the connecting synchronous rope can pull the sliding rack to move in the fixed seat. Under the action of meshing, the rotating stud is driven to rotate, that is, the resistance contact pad moves into the attachment connecting plate to release the resistance and take up the cable.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] The resistance contact pads provide resistance to the cable, limiting its movement during use. The placement of the extended protection plate further restricts movement. When the cable is no longer in use, the winding rollers can be controlled to rewind it, simultaneously driving the rotating shaft. The main pull rope and connecting synchronous rope pull the sliding rack within the fixed seat, engaging with the rotating stud. This causes the resistance contact pads to move towards the connecting plate, releasing resistance during cable winding. This process ensures the resistance contact pads adhere to the cable, stabilizing its position and protecting it during use and winding. Attached Figure Description

[0025] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0026] Please see Figures 1-5In this embodiment of the invention, a cable winding device for a fully mechanized coal mining face includes a winding frame 1 and a fully mechanized mining area 5. The winding frame 1 is located within the fully mechanized mining area 5. A winding roller 11 is rotatably connected inside the winding frame 1. Several cable clamps 2 are provided on the outside of the winding frame 1. The several cable clamps 2 are hinged together by an inner steel frame 21. The several inner steel frames 21 have cable drag grooves 22 for placing cables. Several anti-slip protection components 3 are provided on both sides of the cable clamps 2. The anti-slip protection components 3 include a fixed base 31, a rotating stud 34, an attachment connecting plate 35, and a resistance contact pad 36. A main pull rope 6 is provided on the outside of the winding frame 1. Each winding frame 1 is provided with a resistance contact pad 36. The outer end face of the resistance contact pad 36 contacts the outer wall of the cable to increase resistance. The resistance contact pad 36 drives the rotating stud 34 to rotate. The resistance contact pad 36 slides within the attachment connecting plate 35 to release resistance and wind up the cable.

[0027] In this implementation plan: When using the cable, the cable can be connected to the coal mining machine. Its main body is located at the power station. The position of the cable is controlled by the winding frame 1 and the winding roller 11, so that the overall winding work is carried out within the fully mechanized mining area 5. The cable clamps 2 protect the cable. The inner steel frame 21 connects multiple cable clamps 2, and the position of the cable clamps 2 can be changed according to the working environment. At the same time, when using the cable, the resistance contact pad 36 is located in the cable chute 22. The resistance contact pad 36 provides a certain resistance to the cable. The resistance contact pad 36 is made of soft rubber with a certain elasticity, which allows the resistance contact pad 36 to adhere to the outer wall of the cable, and the cable is embedded in the resistance contact pad. The deeper the pad 36 is inside, the greater the resistance of the resistance contact pad 36 to the cable, and vice versa. During the use of the cable, it can restrict the movement of the cable. The attachment connection plate 35 is fixedly connected to the inner steel frame 21. The attachment connection plate 35 is connected to the inner steel frame 21 so as not to affect the use of multiple cable clamps 2. Both sides of the attachment connection plate 35 are fixedly connected to the extended protection plate 351 for restricting the position of the cable. At the same time, the distribution position of the extended protection plate 351 can further restrict the cable. The extended protection plate 351 is arc-shaped, which can increase the protection area of ​​the cable and reduce the impact of gangue or coal on the cable. At the same time, it can also provide a certain protection for the resistance contact pad 36.

[0028] Without using the cable, the take-up roller 11 can be controlled to wind up the cable. A control assembly 4 is located on the outside of the take-up frame 1. The control assembly 4 includes an outer frame 41, a rotating shaft 42, and a drive disc 43. The rotating shaft 42 is rotatably connected inside the outer frame 41, and the outer frame 41 is fixedly connected to the take-up frame 1. A drive disc 43 for controlling the rotation of the rotating shaft 42 is located on the outside of the outer frame 41. One end of the main pull rope 6 is fixed to the outer wall of the rotating shaft 42, and it can drive the rotating shaft 42 to rotate. When the rotating shaft 42 rotates, it can wind up the main pull rope 6. The fixing seat 31 is fixed to the cable clamp 2. On the outer side, a sliding rack 32 is slidably connected inside the fixed base 31. One end of the main pull rope 6 is fixed to the outermost sliding rack 32. The main pull rope 6 can pull the outermost sliding rack 32 to move, allowing the sliding rack 32 to move within the fixed base 31. The main pull rope 6 has several connecting synchronous ropes 7, and the several sliding racks 32 are all connected through the connecting synchronous ropes 7. The connecting synchronous ropes 7 are elastic bands, which have a certain degree of elasticity during use, making it easy to reset the positions of multiple sliding racks 32. The elasticity can also be achieved by using a spring. The sliding rack 32 and the fixed base 31 can be connected by a spring. A lifting ring can be installed on the sliding rack 32, allowing the main pull rope 6 to be connected to the lifting ring. Simultaneously, the connecting synchronous rope 7 can be wound around this lifting ring and fixed to the next lifting ring. Thus, the connecting synchronous rope 7, under the action of the main pull rope 6, can drive the remaining sliding racks 32 to move. A gear box 33 is provided above the sliding rack 32, and a gear is rotatably connected inside the gear box 33. The gear meshes with the sliding rack 32, and the gear is fixed to the outer wall of the rotating stud 34. The rotating stud 34 is connected to the electric... The cable clamp 2 is threaded, and one end of the rotating stud 34 is rotatably connected to the resistance contact pad 36. When the sliding rack 32 moves, it can drive the gear inside the gear box 33 to rotate under the action of meshing, thereby causing the rotating stud 34 to rotate. The rotating stud 34 and the cable clamp 2 are threaded. Under the action of the thread, the rotating stud 34 can retract, and there is a space for movement on the rotating stud 34, which will not affect the position of the gear. The rotating stud 34 moves the resistance contact pad 36 into the attachment connecting plate 35 and moves away from the cable to release the resistance and rewind the cable.

[0029] like Figures 1-5 As shown, the present invention also provides a method for using a cable winding device for a fully mechanized coal mining face, the specific steps of which are as follows:

[0030] A: When the cable is in use, the resistance contact pad 36 is located in the cable trough 22. The resistance contact pad 36 provides a certain resistance to the cable and can limit the movement of the cable during use. At the same time, the position of the extension protection plate 351 can further limit the movement.

[0031] B: When the cable is not in use, the take-up roller 11 can be controlled to take up the cable. At the same time, the rotating shaft 42 can be driven to rotate. The main pull rope 6 and the connecting synchronous rope 7 can pull the sliding rack 32 to move in the fixed seat 31. Under the action of meshing, the rotating stud 34 is driven to rotate, that is, the resistance contact pad 36 moves into the attachment connecting plate 35 to release the resistance and take up the cable.

[0032] The working principle of this invention is as follows: When using a cable, the cable can be connected to the coal mining machine. Its main body is located at the power station. The position of the cable is controlled by the winding frame 1 and the winding roller 11, so that the overall winding operation is carried out within the fully mechanized mining area 5. The cable clamps 2 protect the cable. The inner steel frame 21 connects multiple cable clamps 2, and the position of the cable clamps 2 can be changed according to the working environment. The attachment connecting plate 35 is connected to the inner steel frame 21, so as not to affect the use of multiple cable clamps 2. At the same time, the cable can resist contact. The pad 36 is located within the cable trough 22. The resistance contact pad 36 provides a certain resistance to the cable. Made of soft rubber with a certain elasticity, the pad 36 adheres to the outer wall of the cable. The deeper the cable is embedded in the pad 36, the greater the resistance, and vice versa. During cable use, it restricts cable movement. Furthermore, the distribution of the extended protection plate 351 further restricts movement. The arc-shaped extended protection plate 351 increases the cable's protection area, reducing the impact of debris or other contaminants on the cable. The influence of coal blocks can be mitigated, and the resistance contact pad 36 can be protected to a certain extent. Without the use of cables, the take-up roller 11 can be controlled to wind up, and the rotating shaft 42 can be driven to rotate. When the rotating shaft 42 rotates, it can wind the main pulling rope 6, which in turn pulls the outer sliding rack 32, allowing it to move within the fixed seat 31. A lifting ring can be installed on the sliding rack 32, allowing the main pulling rope 6 to be connected to the lifting ring. Simultaneously, the synchronous rope 7 can be wound around this lifting ring and fixed to the next lifting ring, thus connecting the synchronous rope 7. The step rope 7, pulled by the main pull rope 6, can drive the remaining sliding rack 32 to move. When the sliding rack 32 moves, it can drive the gear inside the gear box 33 to rotate under the action of meshing, thereby causing the rotating stud 34 to rotate. The rotating stud 34 is threadedly connected to the cable clamp 2. Under the action of the thread, the rotating stud 34 can retract, and there is a space for movement on the rotating stud 34, which will not affect the position of the gear. The rotating stud 34 moves the resistance contact pad 36 into the attachment connecting plate 35 and moves away from the cable to release the resistance and rewind the cable.

[0033] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
