Description

Technical Field

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

[0002] The cable pay-off rack is a device used to support and fix cables when laying cables in projects such as buildings, bridges, and tunnels. It is usually composed of columns, rollers, jacks, and other components, and has the advantages of strong bearing capacity and easy installation. When using the cable pay-off rack, the two columns need to be placed opposite and parallel, and the roller passes through the center of the cable drum and is placed between the two columns. The cable drum is lifted up by the jack to make it off the ground for easy rotation for pay-off. In actual use, it is difficult to accurately control the relative position of the two columns, which makes it difficult for the roller to rotate and affect the pay-off. In addition, the roller is directly mounted on the column. Since the weight of the cable drum is generally large, the resistance between the roller and the column is large when the roller rotates. The pulling force required for pay-off is large, which is easy to cause damage to the cable. At the same time, the heavier cable drum is easy to cause the roller to put too much pressure on the column, causing the column to deform and affecting the stability of the roller. Utility Model Content

[0003] In order to solve the above-mentioned problems, the utility model provides a combined cable pay-off stand which can quickly determine the relative position of the upright posts, has small pay-off resistance and is stable and reliable.

[0004] In order to solve the above technical problems, the technical scheme proposed by the utility model is as follows: a combined cable pay-off frame, comprising a base, a column, a lifting frame, a roller shaft and a jack, the base is provided with two and relatively arranged, the columns are symmetrically arranged on each base, the lifting frame is slidably arranged on the columns, connecting rods are integrally formed at the four corners of the lifting frame, a slide plate is connected to the end of the connecting rod, the slide plate is slidably arranged on the column, a stabilizing rod is connected to the side wall of the connecting rod, the other end of the stabilizing rod is connected to the slide plate, a circular hole is provided in the center of the lifting frame, a plurality of balls are rotatably connected in the hole wall of the circular hole, a through groove penetrating the circular hole is provided on the front side of the lifting frame, two ends of the roller shaft are respectively arranged in the circular holes on both sides, a support plate is connected to the side wall of the column, the lifting frame is driven by the jack fixed on the support plate, and a directional tube and a directional rod are respectively connected to the opposite sides of the two bases, the directional rod matches the directional tube and the end of the directional rod is inserted in the directional tube.

[0005] Furthermore, a stabilizing frame is connected to a side of the column away from the lifting frame, and a lower end of the stabilizing frame is connected to the base.

[0006] Furthermore, the stabilizing rods are arranged on the upper and lower sides of the connecting rod.

[0007] Furthermore, the height of the through groove is higher than the height of the circular hole.

[0008] Furthermore, the directional tube and the directional rod are arranged at the rear end of the base.

[0009] Compared with the prior art, the utility model has the following advantages: the design of the directional rod and the directional tube can quickly place the two bases in parallel and in alignment, ensuring that the roller is stably placed on the lifting frame, and is convenient for smooth rotation to achieve line release. A ball is provided in the circular hole to facilitate the rotation of the roller inside it, which can effectively reduce the resistance between the roller and the lifting frame, thereby facilitating line release. At the same time, the circular hole can also limit the roller to prevent it from deflecting or falling off during rotation, thereby achieving stable line release. The stabilizing frame and the stabilizing rod can increase the stability of the lifting frame, effectively prevent its deformation, and ensure the stable rotation of the roller.

[0015] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0016] Combined with Figure 1 , Attachment Figure 2 A combined cable pay-off rack includes a base 1, a column 2, a lifting frame 3, a roller 4 and a jack 5. The base 1 is provided with two and arranged oppositely. The columns 2 are symmetrically arranged on each base 1. The lifting frame 3 is slidably arranged on the columns 2. A stabilizing frame 14 is connected to the side of the column 2 away from the lifting frame 3. The lower end of the stabilizing frame 14 is connected to the base 1. The stabilizing frame 14 can increase the stability of the column 2.
