Description

Technical Field

[0001] The present invention particularly relates to a low-cost combined pay-off frame. Background Art

[0002] The pay-off rack is used to support and guide the placement of cables or wires in power engineering, ensuring the tension of the cables and the stability of the lines. It is often used in the construction process of high-voltage transmission lines to help install the cables safely and accurately to the predetermined location.

[0003] Most of the existing pay-off racks are placed horizontally, which means that the wires can only be laid horizontally in the left-right direction. When vertical laying is required, that is, vertical laying in the up-down direction, a vertically placed pay-off rack needs to be purchased separately, which is costly. In addition, the structure of the existing pay-off rack is relatively fixed, which is not convenient for supporting coils of wires with different outer diameters and widths to improve the scope of application. For this reason, we propose a low-cost combined pay-off rack. Summary of the invention

A clamping plate 21 is slidably sleeved on the outer surface of the third adjustment bolt 16, and a positioning groove matching with the convex block 22 is opened on the inner wall of the clamping plate 21, which is convenient for better adjusting the position of the clamping plate 21 and locking and fixing it after adjustment. By jointly using the third adjustment bolt 16, the position of the clamping plate 21 or the connecting block 14 is adjusted to reduce the number of parts used and lower the manufacturing cost of the device.

[0041] Preferably, the telescopic column 4 includes a sleeve 401, a telescopic rod 402 and a limit bolt 403. The sleeve 401 is fixed on the first bottom plate 1, and the telescopic rod 402 is slidably connected to the sleeve 401. A limit bolt 403 is arranged on one side of the sleeve 401 and abuts against the telescopic rod 402, which is convenient for adjusting the height of the support block 9 so as to adapt to the pay-off shaft 3 with wire coils of different outer diameters.

[0042] Preferably, the cross-section of the clamping plate 21 is in a "U" shape, there are two clamping plates 21, and there are four third adjustment bolts 16, which is convenient for better horizontal movement of the clamping plate 21.

[0043] Preferably, one end of the upper surface of the third bottom plate 2 is connected with a second adjustment bolt 17 through a threaded part, and the other end of the second adjustment bolt 17 cooperates with the adjustment block 6, which is convenient for adjusting the position of the second bottom plate 7.

[0044] Preferably, the second bottom plate 7 and the adjustment block 6 are perpendicular to each other.

[0046] Preferably, there are two telescopic columns 4.

[0047] The working principle and use process of the present invention are as follows: when in use, according to the outer diameter and width of the wire wound on the outer surface of the pay-off shaft 3, the length of the telescopic rod 402 extending out of the sleeve 401 is adjusted by rotating the limit bolt 403, the height of the support block 9 is adjusted, and then the first adjusting bolt is rotated to adjust the distance between the two support blocks 9, and the two ends of the pay-off shaft 3 are placed on the inner side of the placement groove 10 respectively. At this time, the bearings sleeved at both ends of the pay-off shaft 3 rotate on the inner side of the placement groove 10, and then the stopper 11 is rotated to enter the inner side of the slot. In order to improve stability, the stopper 11 can also be connected and fixed to the support block 9 by a fixing bolt to limit the pay-off shaft 3 bearing from detaching from the inner side of the placement groove 10. When performing horizontal pay-off, the two support plates 12 on the lower surface of the first bottom plate 1 are in contact with the ground, and the pull The moving wire extends out from the pay-off shaft 3, and the two ends of the pay-off shaft 3 rotate with the support block 9 through the placement groove 10. When vertical pay-off is performed, the distance between the support shaft seat 8 and the pay-off shaft 3 can be adjusted to adapt to the distance between the bearings sleeved on the outer surface of the pay-off shaft 3 and its two end parts, so that the support shaft seat 8 is sleeved on one end of the pay-off shaft 3, and the pay-off shaft 3 is supported by the support shaft seat 8. During the adjustment, the movable plate 20 can also be moved to adjust the position of the support seat 19 and the ring plate 18, so that the ring plate 18 corresponds to the retaining ring 5 on different pay-off shafts 3 to provide support and reduce the random movement of the retaining ring 5 during the pay-off process. Then the second bottom plate 7 is rotated to the support plate 12 on one side and placed on the ground, so that the pay-off shaft 3 can be placed vertically for pay-off, and the operation is simple.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
