Description

Technical Field

[0001] The invention relates to the technical field of cable recycling, in particular to a cable reel used for collecting and arranging waste cables. Background Art

[0002] During the use of cables, their performance will gradually degrade over time and reach a scrap state. For cables that have reached a scrap 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. 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 unique variable diameter function of the variable diameter winding roller of the present invention can adjust the gap between the winding roller and the cable coil, thereby effectively eliminating the friction generated during winding and greatly reducing the difficulty of material removal. The setting of the three support frames can provide at least two support points for the rotating shaft, that is, the detachable design of the middle support frame enables the rotating shaft to maintain balance when jumping back and forth between three support points and two support points. At the same time, the detachable design of the middle support frame allows the cable coil to slide smoothly to the storage section, and then the cable coil can be quickly and safely removed without removing the rotating shaft from the base.

[0020] 2. The axial sliding of the sleeve on the rotating shaft is converted into radial movement of the transverse support rod through the connecting rod, thereby changing the diameter of the winding roller. It has a simple structure and is easy to operate. It can ensure that the winding roller maintains stable performance during the diameter change process, thereby improving the neatness and efficiency of cable winding.

[0021] 3. The coordinated use of the positioning plate and the guide groove provides precise guidance for the radial movement of the transverse support rod. The design of the guide groove ensures that the transverse support rod can move along the predetermined trajectory during the diameter change process, avoiding uneven winding or jamming caused by movement deviation. At the same time, the positioning plate also plays a supporting and positioning role, enhancing the overall stability of the winding roller.

[0022] 4. The design of the rotating sleeve and the spiral groove enables the variable diameter drive unit to easily realize the axial movement of the sleeve. By rotating the rotating sleeve, the positioning pin in the spiral groove will push the sleeve to move along the axial direction of the shaft, thereby changing the diameter of the winding roller. It is easy to operate, responds quickly, and can ensure the stability and accuracy of the sleeve during movement.

[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.

[0024] 6. The design of the two positioning parts can ensure that the wrench stays stably at the predetermined position after the diameter change is completed, thereby locking the current diameter of the winding roller, avoiding the change of the winding roller diameter caused by the shaking of the wrench, and improving the stability and reliability of the cable winding.

[0025] 7. The split baffle design makes it easier to take and put the cable coil. The right baffle is fixed to the winding roller, while the left baffle is detachable, which makes it easier to remove or install the cable coil from the winding roller. At the same time, the design of the baffle also takes into account the winding requirements of the cable, ensuring that the cable can be neatly and tightly wound on the winding roller.

[0026] 8. The three outer frames are installed with lifting rings through the spiral lifting part, so that the shaft can rotate coaxially; the middle frame cooperates with the shaft through the semicircular groove to achieve flexible rotation of the shaft, which not only improves the overall stability of the cable drum, but also makes the movement of the shaft smoother.

[0027] 9. By turning the turntable, the screw can be driven to move up and down in the guide hole to adjust the height of the lifting ring. It is not only easy to operate and has a large adjustment range, but also can ensure the stability and accuracy of the lifting ring during the adjustment process.

[0028] 10. The middle frame adopts a fan-shaped design, so that it can fit directly under the rotating shaft and be fixed through the sliding fit of the arc groove and the arc edge. The insertion of the latch further enhances the connection stability between the middle frame and the base. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0039] 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.

[0040] See also Figures 1 to 9 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.

[0041] like Figure 1 to Figure 3 As shown, an external frame 21 in the support frame 2 is then installed on the base 1 near the driving motor 13. First, the triangular frame body is fixed on the base 1 by bolts. Then the screw rod 2121 in the spiral lifting part 212 is taken out, and the turntable 2122 is threadedly connected to the screw rod 2121. Then the screw rod 2121 is inserted into the guide hole at the top of the frame body, and finally the axially horizontally arranged ring 211 is welded to the front end of the screw rod 2121. At this point, the current external frame 21 is installed; another external frame 21 is also fixed on the base 1 in the same installation method.

[0042] After one external frame 21 is installed, the variable diameter winding roller 4, the variable diameter driving part 5 and the sizing part 6 are installed on the rotating shaft 3 in sequence, and then one end of the rotating shaft 3 is inserted into the installed hanging ring 211, and then another external frame 21 is installed. Finally, the other end of the rotating shaft 3 is inserted into another hanging ring 211, and the preliminary installation of the rotating shaft 3 is completed.

[0043] like Figure 3 to Figure 9 As shown, when installing the variable diameter winding roller 4, the variable diameter driving part 5 and the sizing part 6, the right positioning disc 441, the rotating sleeve 52, the limiting ring 51, the sliding sleeve 41 and the left positioning disc 441 are sleeved on the rotating shaft 3 in sequence. Then the right positioning disc 441 in the radial guide part 44 is moved to the corresponding position, and the positioning bolt 444 is used to penetrate the positioning disc 441 and the rotating shaft 3 to fix the positioning disc 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 disc 441 and abuts against the positioning disc 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 disc 441 to prevent the rotating sleeve 52 from axial movement during the rotation process. Finally, the left positioning disc 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 .

[0044] like Figure 7 and Fig. 9 As shown, 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 use the corresponding positioning pin 531 to block the cross bar section 542 at the hole end of the arc hole 4411 to prevent the sliding sleeve 41 from continuing to move axially.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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 rotating shaft 3 is driven to rotate by the driving motor 13 to wind the cable. When the variable diameter winding roller 4 is fully wound with the cable, the driving motor 13 is turned off. Then, the latch 12 is pulled out and the intermediate frame 22 is removed. Then, the left baffle plate 46 is removed, and then the restriction of the limit pin 62 is released. The sliding sleeve 41 is moved to the left by the wrench 54, and each transverse support rod 42 is retracted to form a gap with the inner circle of the cable coil. Finally, the cable coil is pushed from the winding section 31 to the storage section 32. Then, the intermediate frame 22 and the left baffle plate 46 are reinstalled to their original positions. Afterwards, the cable coil is tightened and fixed in the storage section 32 to prevent it from being loose. Next, the outer frame 21 on the left side is removed, the cable coil is taken off the rotating shaft 3, and then the outer frame 21 is reinstalled. At this point, a rolled cable coil is obtained.

[0051] 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.
