Description

Technical Field

[0001] The invention relates to the technical field of cable recycling, in particular to a cable reel with a detachable function. Background Art

[0002] During the use of cables, their performance will gradually degrade over time and reach a scrapped state. For cables that have reached a scrapped state, they are usually recycled and replaced with new cables to maintain the normal working condition of the cable system.

[0003] There are two main cable recycling methods in common use. One is to cut the cable into multiple small sections directly on site, and then pack and transport them back to the recycling factory. The other is to wrap the cable around a cable drum, roll it up for recycling, and then transport it back to the recycling factory together with the cable drum.

[0004] When the first recycling method is adopted, due to the limited processing conditions on site, the cables are usually cut into roughly the same length that is easy to transport. However, after the cables of this length are transported to the processing plant, due to the limitations of various processing equipment, the current length of the cables is prone to being too long or too short, thus failing to meet the requirements of the corresponding processing equipment, and it takes extra time to re-cut the cables, which leads to the first recycling method being gradually abandoned due to its time-consuming and labor-intensive nature.

[0005] In comparison, the coiling recycling method can directly prevent the cable from being cut into multiple small segments in advance, and to a certain extent retain the integrity of the cable, but the coiling recycling method also encounters some difficulties in the actual operation process. In the process of coiling recycling, the cable drum is usually driven to rotate to directly drag and wrap the cable on the cable drum, and then transported to the processing plant together with the cable drum for subsequent processing. However, in actual transportation, it is found that due to its large volume, the cable drum has a small amount of cable transportation per truck, which requires multiple transportations, resulting in increased transportation costs. In order to solve this problem, the staff designed the baffle on one side of the cable drum to be detachable, so as to facilitate the removal of the cable coil from the winding roller of the cable drum. In the actual material collection process, although the baffle on one side has been removed, due to the large winding friction formed between the cable coil and the winding roller during the dragging and winding process, the cable coil is tightly wrapped on the winding roller, making it difficult to easily remove the cable coil from the winding roller, so it is necessary to use the crane to drag to successfully complete the work. It can be seen that the large winding friction formed between the currently used cable drum and the cable coil greatly increases the difficulty of removing the cable coil, and a solution is urgently needed.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention realizes the flexible diameter-changing function in the cable winding process by introducing the design of the variable diameter winding roller. When the cable coil needs to be removed, the variable diameter driving part and the sizing part work together to drive the variable diameter winding roller to reduce the diameter, thereby creating a separation gap between the cable and the winding roller. This innovative design greatly reduces the difficulty of material removal caused by winding friction, making the cable picking and placing process smoother and more efficient.

[0020] 2. The variable diameter winding roller forms a unique double slider mechanism through the combination of the sliding sleeve and the transverse support rod, which has a compact structure and stable operation, and can ensure that during the diameter change process, each transverse support rod can move radially evenly and synchronously, thereby maintaining the integrity and stability of the winding roller surface. In addition, the introduction of the radial guide part further improves the accuracy and reliability of the diameter change action.

[0021] 3. The radial guide part provides precise guidance for the radial movement of the transverse support rod through the ingenious combination of the positioning plate and the guide groove, which not only simplifies the structure of the diameter-changing mechanism, but also improves the accuracy and stability of the diameter-changing action, ensuring the neatness and tightness of the cable during the winding process.

[0022] 4. The variable diameter drive unit realizes the axial movement of the sleeve through the cooperation of the rotating sleeve and the spiral groove, and then drives the variable diameter winding roller to change its diameter. It is not only easy to operate and quick to respond, but also can ensure the stability and accuracy of the sleeve during the movement, avoiding uneven winding or jamming caused by the shaking of the sleeve.

[0023] 5. By swinging the wrench, the rotating sleeve can be easily driven to rotate, thereby achieving the diameter change of the winding roller, which not only improves the convenience of operation, but also makes the diameter change process more intuitive and controllable, reducing the difficulty of operation.

[0024] 6. The sizing part can ensure that the wrench stays stably at the predetermined position after the diameter change is completed through the cooperation of two positioning parts, thereby locking the current diameter of the winding roller. This design avoids the change of the winding roller diameter caused by the shaking of the wrench, improves the stability and reliability of cable winding, and ensures the tightness and neatness of the cable.

[0025] 7. The baffle plate adopts a split design, so that the left baffle plate can be disassembled, which is convenient for removing or installing the cable coil from the variable diameter winding roller, improving the flexibility of the cable reel, reducing maintenance costs, and extending the service life of the cable reel.

[0026] 8. The right baffle is designed with a combination of an outer ring and a support rod, which not only enhances the strength and stability of the baffle, but also makes the connection between the baffle and the variable diameter winding roller tighter, ensuring that the cable winding effect will not be affected by the shaking or deviation of the baffle during the winding process.

[0027] 9. The left baffle adopts a fan-shaped frame design, which makes the baffle easy to disassemble and install. At the same time, the structure of the fan-shaped frame also enhances the strength and stability of the baffle, ensuring the neatness and tightness of the cable during the winding process. In addition, the fan-shaped frame design also makes the baffle lighter and easier to carry and store.

[0028] 10. The shaft is bridged between the two support frames, so that the cable reel can be stably rotated and installed on the support frame. This design not only improves the overall stability of the cable reel, but also enables the cable reel to adapt to different working environments and scenarios. At the same time, the horizontal rotation installation method also makes the winding and placement of cables more convenient and efficient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] See also Figure 1 to Figure 7 When the present invention is in use, the rectangular frame-shaped base 1 is first placed on a horizontal ground, and then the drive motor 13 is installed at one end of the base 1, and the axis of the drive motor 13 is arranged horizontally, and the axis of the drive motor 13 extends in the length direction of the base 1.

[0039] Then, two support frames 2 are installed on the base 1, and both support frames are provided with semicircular grooves 221 opening upward. The two ends of the rotating shaft 3 are rotatably installed in the two semicircular grooves 221 and driven by the driving motor 13.

[0040] The variable diameter winding roller 4 , the variable diameter driving part 5 and the sizing part 6 are sequentially mounted on the rotating shaft 3 , and then the rotating shaft 3 is placed in the two semicircular grooves 221 , thus completing the preliminary installation of the rotating shaft 3 .

[0041] When installing the variable diameter winding roller 4, the variable diameter driving part 5 and the sizing part 6, the right positioning disk 441, the rotating sleeve 52, the limiting ring 51, the sliding sleeve 41 and the left positioning disk 441 are sleeved on the rotating shaft 3 in sequence. Then the right positioning disk 441 in the radial guide part 44 is moved to the corresponding position, and the positioning bolt 444 is passed through the positioning disk 441 and the rotating shaft 3 to fix the positioning disk 441 on the rotating shaft 3. Then the limiting ring 51 is pushed, and the limiting ring 51 pushes the rotating sleeve 52 to move to the right positioning disk 441 and abuts against the positioning disk 441. At this time, the limiting ring 51 is welded to the rotating shaft 3 by welding to limit the rotating sleeve 52 between the limiting ring 51 and the right positioning disk 441 to prevent the rotating sleeve 52 from axial movement during the rotation process. Finally, the left positioning disk 441 is moved to the corresponding position and fixed to the rotating shaft 3 by the positioning bolt 444. At this time, a certain length of sliding clearance is reserved between the left positioning plate 441 and the limiting ring 51 for the sliding of the sliding sleeve 41 .

[0042] Take out the wrench 54, and weld its vertical rod section 541 to the rotating sleeve 52, and insert the vertical rod section 541 into the arc hole 4411 of the positioning plate 441. Then install the sizing part 6. There are four wrenches 54 in total. In order to improve the firmness, four corresponding sets of sizing parts 6 can be installed. After the installation is completed, rotate the wrench 54, and the relative sliding of the spiral groove 521 and the positioning pin 531 is used to move the slideway to the leftmost end, and the corresponding positioning pin 531 is used to block the cross rod section 542 at the hole end of the arc hole 4411 to prevent the sliding sleeve 41 from continuing to move axially.

[0043] Each push-pull rod 53 is welded to the sliding sleeve 41 in sequence around the circumference of the sliding sleeve 41, and during the welding process, the positioning pin 531 is first inserted into the screw groove, and then welded. Then, each connecting rod 43 is installed on the hinge seat 411, and then each transverse support rod 42 is hinged on the connecting rod 43. For the sake of safety, the same transverse support rod 42 is hinged with two connecting rods 43, which have been matched with the sliding sleeve 41 to form a parallel hinge four-link 43 mechanism. While hinged the transverse support rod 42, it is also necessary to slide the guide blocks 443 at both ends thereof into the guide grooves 4421 of the positioning block 442, and the variable diameter winding roller 4, the variable diameter driving part 5 and the sizing part 6 are now installed.

[0044] Next, the baffle is installed. The baffle is divided into a right baffle 45 close to the variable diameter driving part 5 and fixedly connected to the variable diameter winding roller 4, and a left baffle 46 which is detachable for removing the cable coil from the variable diameter winding roller 4.

[0045] The right baffle plate 45 includes an outer ring 451 coaxially sleeved on the outer side of the positioning plate 441 located on the right side, and the outer ring 451 and the positioning plate 441 are connected to each other through a plurality of support rods 452. The support rods 452 are uniformly arranged in sequence around the circumference of the positioning plate 441, and each support rod 452 extends along the radial direction of the positioning plate 441 where it is located.

[0046] The left baffle plate 46 includes a plurality of fan-shaped frames fixed on the outer disk surface of the positioning disk 441 located on the left side, and each fan-shaped frame is uniformly arranged in sequence around the circumference of the positioning disk 441. The fan-shaped frame includes two fixing rods 461 whose heads are fixed to each other and whose tails are connected to a common arc rod 462. Each arc rod 462 is spliced ​​and enclosed to form a baffle ring coaxial with the positioning disk 441, and each fixing rod 461 extends radially at the positioning disk 441 where it is located. The diameter of the baffle ring is the same as the diameter of the outer ring 451. Each fan-shaped frame is fixedly mounted on the positioning disk 441 by bolts.

[0047] The middle frame of the support frame 2 is fan-shaped, and a semicircular groove 221 is coaxially opened at the center of the fan. Two pairs of four ears 11 are installed on the base 1, and an arc groove 111 is formed between the same pair of ears 11. The semicircular groove 221 is coaxially attached to the arc edge 222 at the bottom of the middle frame on the rotating shaft 3, and can slide in the arc groove 111 and rotate to the bottom of the rotating shaft 3. The latch 12 passes through the arc groove 111 and the arc edge 222 at the same time to fix the middle frame 22 on the base 1.

[0048] When the present invention is used to wind the cable, firstly, the wrench 54 is rotated to move the sliding sleeve 41 to the rightmost end, and then the limit pin 62 in the guide sleeve 61 is used to lock the wrench 54 at the end of the arc hole 4411. Then, the driving motor 13 is used to drive the rotating shaft 3 to rotate and wind the cable. When the variable diameter winding roller 4 is fully wound with the cable, the driving motor 13 is turned off. At the same time, the coupling between the driving motor 13 and the rotating shaft 3 is removed, and the connection between the rotating shaft 3 and the driving motor 13 is disconnected. Then, the rotating shaft 3 is lifted and removed from the support frame 2 together with the cable coil. Then, the left baffle plate 46 is removed, and then the restriction of the limit pin 62 is released, and the sliding sleeve 41 is moved to the left by the wrench 54, and each transverse support rod 42 is retracted to generate a gap with the inner ring of the cable coil, and then the cable coil is removed from the variable diameter winding roller 4, and then the left baffle plate 46 is reinstalled to the original position, and the rotating shaft 3 is put back on the two support frames 2 to continue winding the cable.

[0049] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
