Description

Technical Field

[0001] This invention relates to the field of cable recycling equipment technology, and in particular to a cable recycling equipment used in coal mining. Background Technology

[0002] Wires and cables refer to materials used for power, electrical, and related transmission applications. There is no strict boundary between "wires" and "cables." Generally, products with fewer cores, smaller diameters, and simpler structures are called wires; those without insulation are called bare wires, and others are called cables. Conductor cross-sectional areas with larger cross-sectional areas (greater than 6 square millimeters) are called large cables, and smaller ones (less than or equal to 6 square millimeters) are called small wires, also known as building cables. In coal mine tunnels, cables of different sizes are used. When it is necessary to recover or deploy these cables, cable recovery devices are needed. However, existing cable recovery devices often result in cables piling up, hindering the recovery process. Summary of the Invention

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0026] Example 1

[0027] Reference Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a cable recycling device for coal mining. The cable recycling device for coal mining includes a fixing component 100, a storage component 200, and an anti-accumulation component 300. The fixing component 100 is used to install the storage component 200 and the anti-accumulation component 300. The storage component 200 is used to wind up the cable, and the anti-accumulation component 300 is used to prevent the cable from accumulating on the storage component 200.

[0028] Specifically, the fixing component 100 includes a base 101, which is used to install the storage component 200 and the anti-stacking component 300. In use, the base 101 is placed on a flat surface. The storage component 200 includes a rotating component 201, which is rotatably mounted on the base 101. The rotating component 201 is used to wind the cable. During the rotation of the rotating component 201, the cable is gradually stored on the rotating component 201. The anti-stacking component 300 includes a reciprocating component 301, which is disposed on the base 101 and is connected to the rotating component 201. The reciprocating component 301 drives the cable to reciprocate along the length of the rotating component 201. In use, the cable is first laid on the reciprocating component 301 and then wound around the rotating component 201. During the rotation of the rotating component 201, the reciprocating component 301 reciprocates, so that the cable is evenly stored on the rotating component 201, preventing the cable from stacking.

[0029] In use, first place the base 101 on a flat surface, then lay the cable on the reciprocating component 301, and then fix the end of the cable to the rotating component 201. At this time, the reciprocating component 301 applies a vertical downward pressure to the cable, so that the cable between the reciprocating component 301 and the rotating component 201 is in a taut state. Then the rotating component 201 rotates to wind and retract the cable. When the rotating component 201 rotates, the reciprocating component 301 also moves back and forth synchronously, so that the cable on the reciprocating component 301 constantly changes the direction of the cable inlet, thereby avoiding the accumulation of cable on the rotating component 201.

[0030] Example 2

[0031] Reference Figures 1-5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0032] Specifically, the base 101 includes a base plate 101a, a first mounting post 101b, a second mounting post 101c, and a handrail 101d; the first mounting post 101b and the second mounting post 101c are both fixed to the base 101 with bolts, and the first mounting post 101b and the second mounting post 101c are arranged parallel to each other. The handrail 101d is located at the tail of the base 101, and rollers 101e are provided at the four corners of the bottom of the base 101 to facilitate the operator to move the device.

[0033] Preferably, the rotating component 201 includes a first mounting plate 201a and a second mounting plate 201b; the first mounting plate 201a is rotatably mounted on the first mounting post 101b, and the second mounting plate 201b is rotatably mounted on the second mounting post 101c; a rotating shaft 201c is provided between the first mounting plate 201a and the second mounting plate 201b, with both ends of the rotating shaft 201c passing through the first mounting plate 201a and the second mounting plate 201b respectively, and both ends of the rotating shaft 201c being fixedly connected to the first mounting plate 201a and the second mounting plate 201b respectively; a drive motor 201d is provided on the second mounting plate 201b, and the output end of the drive motor 201d is fixedly connected to the right end of the rotating shaft 201c, and the drive motor 201d drives the first mounting plate 201a, the rotating shaft 201c and the second mounting plate 201b to rotate synchronously, thereby enabling the winding and recycling of cables.

[0034] Preferably, the rotating shaft 201c has a sliding cavity 201c-1 inside, the central axis of the sliding cavity 201c-1 coincides with the central axis of the rotating shaft 201c, the left end of the sliding cavity 201c-1 passes through the left end of the rotating shaft 201c, and a rectangular groove 201c-2 is formed on the circumferential surface of the rotating shaft 201c, the rectangular groove 201c-2 is connected to the sliding cavity 201c-1, and the length direction of the rectangular groove 201c-2 coincides with the length direction of the rotating shaft 201c; the rotating component 201 also includes a connecting block 201e, a connecting column 201f, and a connecting rod 201g. The sliding sleeve 201h and the telescopic rod 201i are included; the connecting block 201e is slidably installed in the sliding cavity 201c-1, and the connecting block 201e can slide along the length direction of the sliding cavity 201c-1. A push rod is provided at the left end of the connecting block 201e, extending from the left end of the rotating shaft 201c; the left and right ends of the connecting column 201f are slidably installed on the first mounting plate 201a and the second mounting plate 201b, respectively. A spring is provided at the left end of the connecting column 201f, and the spring is connected to the first mounting plate 201a. The spring forces the connecting column 201f to... The tendency to move towards the direction of rotation axis 201c; the right end of connecting rod 201g is hinged to connecting post 201f, and the left end of connecting rod 201g is hinged to connecting block 201e; the left end of sliding sleeve 201h is rotatably connected to connecting rod 201g, and the right end of sliding sleeve 201h is recessed inward to form sliding groove 201h-1; the left end of telescopic rod 201i is elastically installed in sliding groove 201h-1, and the right end of telescopic rod 201i is hinged to rotation axis 201c; when the operator pushes connecting block 201e to the right, connecting block 201e drives connecting post 201f through connecting rod 201g. When 01f expands outward, the connecting rod 201g rotates, causing the sliding sleeve 201h to rotate. When the sliding sleeve 201h rotates, relative sliding occurs between the sliding sleeve 201h and the telescopic rod 201i, and the telescopic rod 201i also rotates synchronously. By adjusting the expansion degree of the connecting post 201f, the operator can make the rotating part 201 adapt to cables of different diameters, avoiding the connection post 201f from opening too little and making it difficult to wind larger diameter cables, thus avoiding severe bending of the cables. At the same time, the floating connecting post 201f has a faster adjustment speed than the connecting post 201f installed by threads.

[0035] Preferably, the rotating component 201 further includes a ratchet 201j, a first abutting block 201k, and a second abutting block 201m; the ratchet 201j is elastically mounted on the first mounting plate 201a, and the ratchet 201j is telescopic; the connecting post 201f is provided with ratchet teeth 201f-1, which are adapted to engage with the ratchet 201j, and the ratchet 201j can restrict the movement of the connecting post 201f towards the rotating shaft 201c through the ratchet teeth 201f-1. However, it does not restrict the connecting post 201f from moving away from the rotation axis 201c; the first abutment block 201k and the second abutment block 201m are both elastically mounted on the rotation axis 201c. The first abutment block 201k is adapted to move away from the central axis of the rotation axis 201c, and the second abutment block 201m is adapted to move along the length of the rotation axis 201c. The first abutment block 201k abuts against the second abutment block 201m, and the second abutment block 201m is adapted to... The first contact block 201k, made of lead, copper, or other high-density metal, abuts against the telescopic rod 201i. When the rotating shaft 201c rotates, the first contact block 201k, under centrifugal force, moves away from the central axis of the rotating shaft 201c. The first contact block 201k then presses against the second contact block 201m, causing the second contact block 201m to move to the left. The second contact block 201m then abuts against the telescopic rod 201i, thus restricting the rotation of the telescopic rod 201i, and consequently restricting the rotation of the sliding sleeve 201h and the connecting rod 201g. This prevents the connecting post 201f from moving outward under centrifugal force when the cable is not yet fully wrapped around it at the beginning of the cable winding process. This keeps the connecting post 201f stable. Furthermore, the faster the output shaft of the drive motor 201d rotates, the tighter the first contact block 201k drives the second contact block 201m to abut against the telescopic rod 201i, and the more stable the connecting post 201f becomes.

[0036] Preferably, the reciprocating component 301 includes a mounting base 301a, a first pulley 301b, a second pulley 301c, and a third pulley 301d; the mounting base 301a is fixed on the base 101; the first pulley 301b is connected to the drive motor 201d, and the central axis of the first pulley 301b coincides with the central axis of the rotating shaft 201c; the second pulley 301c is rotatably mounted on the second mounting post 101c, and the third pulley 301d is rotatably mounted on the base 101; the second pulley 301c is simultaneously connected to both the first pulley 301b and the third pulley 301d; in use, the drive motor 201d drives the first pulley 301b to rotate, the first pulley 301b drives the second pulley 301c to rotate via a belt, and the second pulley 301c drives the third pulley 301d to rotate via a belt.

[0037] Furthermore, the reciprocating component 301 also includes a slide rail 301e, a reciprocating screw 301f, and a clamping block 301g; two mounting seats 301a are provided, which are arranged parallel to each other, and the slide rail 301e is disposed between the two mounting seats 301a. The slide rail 301e is fixedly connected to the mounting seats 301a, and the length direction of the slide rail 301e is parallel to the length direction of the rotating shaft 201c; the reciprocating screw 301f is rotatably mounted on the two mounting seats 301a, and the right end of the reciprocating screw 301f passes through the right mounting seat 301a and extends to the outside of the right mounting seat 301a. The length direction of the reciprocating screw 301f is parallel to the length direction of the rotating shaft 201c. The third pulley 301d is connected to the reciprocating screw 301f and is fixed to the right end of the reciprocating screw 301f. The clamping block 301g is slidably mounted on the slide rail 301e and is connected to the reciprocating screw 301f. The reciprocating screw 301f includes a lever body and a sliding block. The sliding block is slidably mounted on the lever body. The sliding block of the reciprocating screw 301f is fixedly connected to the clamping block 301g by bolts. In use, the drive motor 201d drives the reciprocating screw 301f to rotate sequentially through the first pulley 301b, the second pulley 301c, and the third pulley 301d. The reciprocating screw 301f drives the clamping block 301g to reciprocate through the sliding block.

[0038] Furthermore, the top surface of the clamping block 301g is recessed downward to form a U-shaped groove 301g-1, and the central axis of the U-shaped groove 301g-1 is perpendicular to the length direction of the slide rail 301e; the reciprocating component 301 also includes a pressing block 301k, which is rotatably mounted on the clamping block 301g; in use, the cable is placed in the U-shaped groove 301g-1 of the clamping block 301g, and then a vertical downward force is applied to the cable by the pressing block 301k, thereby tightening the cable between the clamping block 301g and the rotating component 201, so that the cable is more closely attached to the rotating component 201.

[0039] Furthermore, the compression block 301k is equipped with a ratchet 301h, and the clamping block 301g is equipped with a pawl. The pawl engages with the ratchet 301h. An abutment piece is elastically installed on the compression block 301k, which is suitable for contacting the cable. In use, the operator can adjust the pressure of the compression block 301k on the cable by rotating the compression block 301k. The elastically installed abutment piece can buffer the cable and prevent the cable from being excessively jammed.

[0040] Furthermore, the fixing assembly 100 also includes a brake pin 102. The second mounting post 101c is provided with a pin hole, and the brake pin 102 is elastically installed in the pin hole. The brake pin 102 is adapted to restrict the rotation of the second mounting plate 201b. An L-shaped groove is provided on the inner wall of the pin hole, and a limiting rod is provided on the circumferential surface of the brake pin 102. The limiting rod is adapted to slide in the L-shaped groove, and a return spring is sleeved on the brake pin 102. The return spring is connected to the pin hole. During transportation, the operator pushes and rotates the brake pin 102 inward, so that the limiting rod of the brake pin 102 is locked in the L-shaped groove, thereby locking the second mounting plate 201b by the brake pin 102, preventing the second mounting plate 201b from rotating during transportation, thus keeping the rotating part 201 from shaking continuously due to bumps during transportation. When in use, the brake pin 102 is pulled outward, so that the brake pin 102 is disengaged from the second mounting plate 201b.

[0041] To facilitate understanding of the cable recovery device used in this coal mine, its working process is briefly described below:

[0042] During the preparation phase, the operator pushes the connecting block 201e to the right. The connecting block 201e drives the connecting post 201f to expand outward through the connecting rod 201g. The rotation of the connecting rod 201g drives the sliding sleeve 201h to rotate. The sliding sleeve 201h rotates, and relative sliding occurs between the sliding sleeve 201h and the telescopic rod 201i. The telescopic rod 201i also rotates synchronously. By adjusting the expansion degree of the connecting post 201f, the operator can make the rotating part 201 adapt to cables of different diameters, avoiding the connection post 201f from opening too little and making it difficult to wind larger diameter cables, thus avoiding severe bending of the cables.

[0043] During the winding stage, when the drive motor 201d drives the first mounting plate 201a, the second mounting plate 201b, and the rotating shaft 201c to rotate synchronously, the first abutment block 201k, under centrifugal force, will move away from the central axis of the rotating shaft 201c. The first abutment block 201k will then press against the second abutment block 201m, causing the second abutment block 201m to move to the left. The second abutment block 201m will then abut against the telescopic rod 201i, thereby restricting the rotation of the telescopic rod 201i, and consequently restricting the sliding sleeve 201h and the connecting rod 201. The 1g rotation prevents the connecting post 201f from moving outward under centrifugal force when the cable is not fully wrapped around it at the beginning of the rotation and cable winding, thus keeping the connecting post 201f stable. The drive motor 201d drives the reciprocating screw 301f to rotate through the first pulley 301b, the second pulley 301c, and the third pulley 301d in sequence. The reciprocating screw 301f drives the clamping block 301g to reciprocate through the sliding block. This ensures that the cable is evenly wound on the rotating part 201, avoiding accumulation.

[0044] During the unwinding stage, drive motor 201d reverses, the principle being the same as the winding stage described above.

[0045] During the transportation phase, the operator pushes and rotates the brake pin 102 inward, causing the limit rod of the brake pin 102 to be locked in the L-shaped slot. This locks the second mounting plate 201b in place, preventing the second mounting plate 201b from rotating during transportation and thus keeping the rotating part 201 from shaking due to bumps during transportation.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
