[0002] Power cables are usually wound on cable drums as the core carrier for convenient transportation, storage, custody and laying. In actual applications, after the cable drum is placed stably, the process of manually dragging the cable coils one by one is not only labor-intensive and significantly reduces the efficiency of retraction and release, but also for large cables, this operation is very easy to wear the outer protective layer of the cable during the dragging process, thereby increasing safety risks and hidden dangers. A more efficient and safe cable retraction and release solution is urgently needed.

[0003] When cable retracting devices are used outdoors, they face complex use environments, which can also exacerbate the problem of cable disorder during the retraction process. Although existing technologies can control the arrangement of cables to a certain extent, in the face of the variability of outdoor environments, cable overlap, uneven spacing, and irregular arrangement still occur from time to time, which not only affects the service life of the cables, but also may pose a safety hazard to the normal operation of the equipment.

During the dragging process, the guide wheel 10 rotates to reduce friction on the cable.

[0028] In order to realize the forward and reverse rotation of the screw rod, this embodiment mainly uses a reciprocating drive component.

The drive wheel is transmission-connected to the bevel gear set on the roller shaft 2, so that the rotational power of the roller shaft 2 is connected to the drive shaft 17, that is, the drive shaft 17 is in a rotating state when the line is being delivered or reeled in.

[0030] The center bevel gear 16 is fixed on one side of the driving screw 5, that is, when the center bevel gear 16 rotates, it will drive the driving screw 5 to rotate. The first side bevel gear 18 and the second bevel gear are symmetrically arranged on the driving shaft 17 and mesh with the two sides of the center bevel gear 16. In this embodiment, the first side bevel gear and the second side bevel gear are rotationally configured on the driving shaft 17 and will not rotate with the driving shaft 17. When the switching sleeve is connected to the corresponding driving sleeve, the driving sleeve drives the corresponding bevel gear, and the first side bevel gear and the second side bevel gear choose to rotate with the driving shaft 17 and drive the center bevel gear 16 and the driving screw 5 to rotate.

[0031] In terms of drive access, in this embodiment, a first drive sleeve 19 fixedly connected to the first side bevel gear 18 and a second drive sleeve 21 fixedly connected to the second side bevel gear 20 are rotatably sleeved on both sides of the drive shaft 17; a switching sleeve 22 is slidably and transmission-connected through a spline shaft in the middle of the drive shaft 17, that is, the switching sleeve 22 can translate relative to the drive shaft 17 and is always in a rotating state, and engagement grooves that can engage with each other are arranged between the two sides of the switching sleeve 22 and the first drive sleeve 19 and the second drive sleeve 21, and power access is achieved through the matching access of the engagement groove and the engagement tooth, and a shifting groove 23 adapted to be connected to the shifting rod 24 is provided in the middle of the switching sleeve 22, and the shifting groove 23 is arranged along the center of the switching sleeve 22, and the shifting rod 24 is always in the shifting groove 23.

[0032] The swing plate 25 is rotatably arranged on the frame 1, and side plates are arranged on both sides thereof. An arc surface is arranged at the bottom thereof, and the center of the arc surface is the swing point. After passing the swing point, the swing plate 25 can swing freely to one side, that is, the swing point in the middle is a point that is not easy to pass.

[0033] The rotating shaft of the swing plate 25 is transmission connected with the rotating shaft of the lever 24; the specific connection method is that the rotating shaft of the lever 24 is transmission connected with the bevel gear set, and the rotating shaft on one side of the bevel gear set is transmission connected with the rotating shaft 26 of the swing plate, and the control connection between the rotating shaft of the swing plate 25 and the rotating shaft of the lever 24 is realized according to the orientation.

[0034] A limit seat 27 is provided on the frame 1, and a vertical hole corresponding to the middle area is vertically provided on the limit seat 27, a sliding block is slidably mounted in the vertical hole, a roller 29 is rotatably provided on the sliding block, and the bottom of the sliding block is connected to the limit seat 27 via a top spring 28. In the specific structure, a limit groove is provided on the upper part of the limit seat 27, and the lower part of the swing plate 25 is adapted to be assembled in the limit groove, and the side plate can be blocked on the outside of the limit groove. Through the limitation of the limit groove, positioning is provided for the swing of the swing plate 25, and the lower part of the swing plate 25 can be pressed against the roller 29. When the roller 2 When the swing plate 25 swings to the swing point, the top spring 28 is compressed and needs additional power to swing over. After passing the swing point, the swing plate 25 is at the extreme positions on both sides under the pushing of the top spring 28 and the limitation of the side plates. After receiving the drive, the swing plate 25 swings from one extreme position to another extreme position, thereby generating a rotational driving force of a certain angle during the swinging process. The driving force is connected to the lever 24 to realize the fixed-angle swing of the lever 24, and the bevel gear on one side is switched immediately, so that the screw rod is finally in a forward or reverse state.

[0035] In order to drive the pendulum plate 25 to pass the swing point, a slide rod 30 is provided on one side of the side plate in this embodiment. One side of the spring 33 is connected to the push rod 14, and the other side is connected to the translation seat 31. A long hole 32 is vertically provided on the translation seat 31. The slide rod 30 is adapted to slide in the long hole 32. The driving force of this embodiment comes from the push rod 14. The push rod 14 provides a force and uses the spring 33 to realize the translation of the translation seat 31, thereby realizing the pendulum plate 25 passing the swing point through the long hole 32 and the slide rod 30.

[0036] like Figure 3 As shown in , when in use, the swing plate 25 is in the right extreme position, the push rod 14 is in a free state, and the spring 33 is also in a natural force-free state. Then the push rod 14 moves to the right and provides tension to the spring 33. The spring 33 stretches to accumulate energy and then pulls the translation seat 31 to translate. The translation seat 31 drags the swing plate 25 to the right through the long hole 32 and the slide rod 30 structure to swing, and the limit seat 27 is in a fixed state. The middle area of ​​the swing plate 25 passes the swing point and enters the left area. At this time, the push rod 14 moves a distance to the right, and the translation seat 31 also moves a distance to the right. The swing plate 25 swings to the right by a certain angle, that is, from the right extreme position to the left extreme position. The spring 33 is converted into the elastic force of the spring 33 through the force provided by the rightward movement of the push rod 14, so that the swing plate 25 passes the swing point and is maintained at the corresponding extreme position under the action of the top spring 28.

[0037] The swing plate 25 swings at a certain angle and transmits it to the rotating shaft of the lever 24 through the bevel gear set. The lever 24 rotates, driving the switching sleeve to translate and maintain it at two extreme positions, so that the corresponding side bevel gear is connected to the center bevel gear 16, so that the drive screw 5 is reversed. It is worth noting that in this embodiment, the actual swing is that the sliding sleeve 7 and the limit sleeve 8 slide to the extreme position on one side, and the guide wheel also follows to this position, that is, the extreme position on one side, and then moves in the opposite direction, which is consistent with the cable winding method, and provides a movable and adaptive cable outlet guide wheel for the cable outlet, which greatly reduces the wear during the outlet. At the same time, the device can be used for winding, and provides special tools for spiral winding, which is easy to use and greatly improves work efficiency.

Through this structure, the first baffle 12 and the second baffle 12 are pre-configured in the positioning sleeve 6, and then the fixing plates are fixed at both ends of the positioning sleeve 6 by bolts or welding. A through hole for the through rod to pass through is provided on the fixing plate. The through rod has two threaded sections, and is threadedly connected to the first baffle 12 and the second baffle 12 in sequence, and can slide in the frame 1 and the fixing plate 15.

[0040] The end of the positioning sleeve 6 is provided with multiple groups of sliding holes, and the baffle 12 is provided with ribs adapted to the sliding holes, which extend from the sliding holes and form a blocking portion outside the positioning sleeve 6. The sliding holes have the same length, and the first baffle 12 and the second baffle 12 can be located at the same side of the sliding holes at the same time, and can be translated and moved under the action of the limiting sleeve 8. That is, due to the constraints of the two baffles 12, the distance moved by the push rod 14 is a fixed length d1, and the distance moved by the swing plate 25 is also a fixed length point d2, and d1=d2, Embodiment 3: This embodiment further illustrates the installation method of the cable rack.
