Description

Technical Field

[0001] This utility model relates to the field of power construction equipment technology, specifically a cable unwinding frame. Background Technology

[0002] Depending on their purpose, cable laying racks are also known as cable reel supports, conductor reel supports, cable laying brackets, etc. According to their lifting methods, they can be divided into hydraulic cable laying racks and mechanical cable laying racks.

[0003] For example, a cable unwinding frame for power construction, as disclosed in announcement number "CN219585512U," uses a mounting sleeve and matching limit bolts. The hexagonal structure at both ends of the support rod connects to the mounting sleeve, preventing relative rotation between the support rod and the mounting sleeve. The limit bolts further limit the rotation, ensuring the stability of the support rod during rotation. The rotational connection between the mounting sleeve and the mounting base makes driving the cable roller more effortless. However, when not unwinding, moving the base of this cable unwinding frame can easily cause the support rod to rotate, leading to the rotation of the cable roller. This causes the cable to gradually loosen and come into contact with the ground, resulting in cable wear. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that when the base is not being unloaded, moving it can easily cause the support rod to rotate, which in turn causes the cable roller to rotate, causing the cable to gradually loosen and come into contact with the ground, resulting in cable wear. Therefore, a cable unwinding frame is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a cable unwinding rack, including a support plate and a housing. The support plate has a housing inside each housing, and each housing has a limiting mechanism inside each housing. The limiting mechanism includes a knob and a first bolt. The end of the knob is fixedly connected to a threaded rod. Both sides of the threaded rod are rotatably connected to the housing through bearings. The outer wall of the threaded rod is threadedly connected to a slider. Both sides of the slider are rotatably connected to rollers through bearings. The outer walls of the rollers are in contact with the housing. The end of the first bolt is abutted against the housing.

[0007] Preferably, a plurality of vertical rods are fixedly connected above the slider, and the outer walls of the vertical rods are slidably connected to the box body.

[0008] Preferably, the upper ends of the vertical rods are all fixedly connected to the limiting plates, the outer wall of the first bolt is threadedly connected to the knob, and the upper part of the limiting plates is pressed against the feeding roller.

[0009] Preferably, the inner walls of the support plates are rotatably connected to sleeves via bearings, and the inner walls of the sleeves are slidably connected to the rotating rods.

[0010] Preferably, the outer wall of the rotating rod is fixedly connected to the inner wall of the locking block, and the outer wall of the locking block is inserted into the sleeve.

[0011] Preferably, the inner side of each rotating rod is fixedly connected to the wire feeding roller, and the front side of the housing is connected to the maintenance door by multiple screws.

[0012] Preferably, the sleeve and the rotating rod are connected by a second bolt, and the outer side of the box is fixedly connected to the support plate by a bracket.

[0013] The cable unwinding rack proposed in this utility model has the following advantages: through the cooperation of the housing and the limiting mechanism, the knob rotation drives the threaded rod to rotate, and the two rollers can limit the rotation of the slider. The slider and the threaded rod can only move up and down. The movement of the slider drives the vertical rod and the limiting plate to move, and at the same time, it can drive the rollers to roll along the inner wall of the housing. When the upper part of the limiting plate is pressed against the unwinding roller, the knob is stopped, and then the first bolt is rotated so that the end of the first bolt is pressed against the housing, which can limit the rotation of the knob. This allows the limiting plate to limit the rotation of the unwinding roller. When the support plate is moved, the unwinding roller will not rotate, reducing the situation where the cable is loosened and moved on the ground and is rubbed. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] See attached document Figure 1-5In this embodiment, a cable unwinding rack includes a support plate 1 and a housing 2. The housing 2 is provided inside the support plate 1. The housing 2 is provided inside the housing 2. The limiting mechanism 5 includes a knob 501 and a first bolt 507. A threaded rod 502 is fixedly connected to the end of the knob 501. Both sides of the threaded rod 502 are rotatably connected to the housing 2 through bearings. The outer wall of the threaded rod 502 is threadedly connected to a slider 503. Both sides of the slider 503 are rotatably connected to rollers 504 through bearings. The outer walls of the rollers 504 are in contact with the housing 2. The end of the first bolt 507 is pressed against the housing 2. Rotating the knob 501 drives the threaded rod 502 to rotate. The two rollers 504 can limit the rotation of the slider 503. The slider 503 and the threaded rod 502 can only move up and down. The movement of the slider 503 drives the vertical rod 505 and the limiting plate 506 to move. At the same time, it can drive the rollers 504 to roll along the inner wall of the housing.

[0022] Multiple vertical rods 505 are fixedly connected above the slider 503. The outer walls of the vertical rods 505 are slidably connected to the housing 2. The upper ends of the vertical rods 505 are fixedly connected to the limiting plate 506. The outer wall of the first bolt 507 is threadedly connected to the knob 501. The upper part of the limiting plate 506 is pressed against the wire feeding roller 3. The inner wall of the support plate 1 is rotatably connected to the sleeve 8 through the bearing. The inner wall of the sleeve 8 is slidably connected to the rotating rod 4. The outer wall of the rotating rod 4 is fixedly connected to the inner wall of the clamping block 7. The outer wall of the clamping block 7 is inserted into the sleeve 8. The inner side of the rotating rod 4 is fixedly connected to the wire feeding roller 3. The front side of the housing 2 is connected to the inspection door 9 through multiple screws. The outer side of the housing 2 is fixedly connected to the support plate 1 through the bracket.

[0023] Working principle:

[0024] When using a cable unwinding rack:

[0025] The operator can lift the wire feeding roller 3 using a forklift or similar structure, and then insert the rotating rods 4 on both sides of the wire feeding roller 3 into the sleeve 8. After the locking block 7 enters the sleeve 8, the operator rotates multiple second bolts 6 to fix the rotating rods 4 onto the sleeve 8. Then, the operator pulls the cable wound on the surface of the wire feeding roller 3, thereby driving the wire feeding roller 3 to rotate, which in turn drives the sleeves 8 on both sides to rotate, causing the cable wound on the surface of the wire feeding roller 3 to loosen and perform wire feeding. When not in use, the cable can be retracted by rotating the handle on the outside of the sleeve 8 in the opposite direction.

[0026] After the cable is retracted, the operator rotates the knobs 501 on both sides. The rotation of the knobs 501 drives the threaded rod 502 to rotate. The two rollers 504 can restrict the rotation of the slider 503. The slider 503 and the threaded rod 502 can only move up and down. The movement of the slider 503 drives the vertical rod 505 and the limiting plate 506 to move. At the same time, it can drive the rollers 504 to roll along the inner wall of the box. When the upper part of the limiting plate 506 is pressed against the wire feeding roller 3, the operator stops rotating the knob 501. Then, the operator rotates the first bolt 507 so that the end of the first bolt 507 is pressed against the box 2. This can restrict the rotation of the knob 501, so that the limiting plate 506 can restrict the rotation of the wire feeding roller 3. When the support plate 1 is moved, the wire feeding roller 3 will not rotate, reducing the possibility of the cable coming loose and coming into contact with the ground and being rubbed.

[0027] Turning multiple screws will open the inspection door 9, allowing maintenance of the internal structure of the housing 2. When it is necessary to replace the pay-off roller 3 with other types of cables wound on it, the operator unscrews the second bolts 6 on both sides, moves the two support plates 1 outward, and moves the rotating rod 4 out of the sleeve 8. Then the operator can reinstall the pay-off roller 3 with other types of cables wound on it (i.e., cables of different thicknesses).

[0028] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
