Description

Technical Field

[0001] The utility model belongs to the technical field of cable pay-off, and in particular relates to a high-stability cable pay-off rack. Background Art

[0002] Cable pay-off refers to the process of releasing the cable from its storage reel or drum and laying it in a specific path and manner. In the process of cable pay-off, the cable pay-off rack is a common construction tool, which plays an important role in the power construction site. The cable pay-off rack in the prior art mainly consists of two symmetrically arranged brackets and an axle rod. When laying the cable, the whole cable is placed on the bracket through the axle rod, and then the cable is pulled for laying.

[0003] For example, a Chinese utility model patent with announcement number CN220264743U discloses an adjustable cable pay-off rack, in which a U-shaped rack is provided and the cable can be pulled to move the U-shaped rack downward, and the downward movement of the U-shaped rack can trigger a contact sensor, which starts a servo motor and drives the winding shaft on the turntable to rotate to release the cable. When the cable stops being pulled, the contact sensor stops triggering and the servo motor is shut down. Since the servo motor is an electromagnetic brake motor, the turntable can be prevented from continuing to rotate after the servo motor is powered off, and the winding shaft can be prevented from continuing to rotate due to inertia and releasing excess cable.

[0004] However, the height position of the cable reel of the device cannot be adjusted. When performing cable pay-off work at some higher positions, it is inconvenient to adjust the overall height of the device, so that when the cable is being paid-off, the cable is easily shaken due to the pulling caused by the height difference, and the stability is poor.

[0005] In summary, there is currently a need for a cable pay-off stand that can conveniently adjust the height of the cable winding roller. Utility Model Content

[0035] The implementation principle of a high-stability cable pay-off stand in the embodiment of the present application is as follows: after pushing the device to the work site, rotate the small screw so that the support column abuts against the ground, thereby fixing the device as a whole, and then rotate the turntable according to the height requirement, the turntable drives the fourth bevel gear, so that the fourth bevel gear drives the third bevel gear to rotate, so that the second bevel gear drives the first bevel gear to rotate, so that the worm 18 drives the two worm wheels 17 to rotate, and the rotation of the worm 18 drives the two bidirectional screws 23 to rotate, so that the two moving seats 19 are close to each other, so that the scissors fork 21 drives the top plate 2 to rise, and drives the device as a whole to rise, so that when the cable winding roller is performing the pay-off work, the height of the cable winding roller is consistent with the vertical height of the pay-off, so that it is convenient to pull the cable when the cable is paid-off, and the cable pay-off work is more stable.

[0036] After the height adjustment is completed, the cable winding roller is placed on the plug rod on the side support plate 4, and the servo motor 14 is started. The servo motor 14 drives the screw rod 3 to rotate, so that the inner support plate 4 moves outward. During the movement of the support plate 4, the moving rod 7 moves outward, and the moving rod 7 moves along the linear slide groove on the moving block 8. When the moving rod 7 abuts on the inner wall of the linear slide groove, the moving block 8 drives the push plate 9 to move sideways, so that the push rod 10 and the displacement rod 13 move to the same side, and the sleeve 11 is driven to move to the same side by the connecting rod, so that the abutment plate 12 moves outward until the abutment plate 12 abuts on the inner wall of the cable winding roller. When the cable winding roller is installed, the abutment plate 12 automatically expands outward to abut against the inner wall of the cable winding roller, making the cable winding roller more stable when paying out the line.

[0037] When the cable winding roller is to be removed, the servo motor 14 is reversed, so that the screw rod 3 drives the inner support plate 4 to move inward, so that the moving rod 7 moves inward along the linear slide groove of the moving block 8 until the limit bar on the moving rod 7 abuts against the inner wall of the moving limit groove, thereby driving the moving block 8 to move sideways, so that the push plate 9 drives the push rod 10 and the displacement rod 13 to move toward the same side as mentioned above, so that the sleeve 11 moves toward the same side as mentioned above, and the abutment plate 12 shrinks inwardly. At the same time, the push rod 10 pushes the cable winding roller sideways until the cable winding roller is pushed onto the receiving plate 5, so that when the above-mentioned support plate 4 on the same side moves outward, the cable winding roller is automatically pushed down, thereby improving the overall disassembly efficiency of the device.
