Detailed Description

As shown in fig. 1-2, an adjustable pay-off rack comprises two symmetrically arranged rack bodies 1. Each frame body 1 comprises a base 2, and two vertical sliding rods 3 are symmetrically and fixedly arranged in the middle of the upper part of each base 2. The upper ends of the two sliding rods 3 are fixedly provided with a horizontal top plate 4, and four supporting rods 5 are fixedly arranged between four corners of the top plate 4 and the base 2 in an inclined manner.

A plurality of jacks 6 are uniformly formed in each sliding rod 3, two first sliding sleeves 7 are symmetrically and slidably arranged at the lower half parts of the two sliding rods 3 of each frame body, an installation seat 8 is fixedly arranged between the two first sliding sleeves 7, a supporting wheel seat 9 is arranged at the upper part of the installation seat 8, two second sliding sleeves 10 which are respectively and slidably matched with the two sliding rods 3 are fixedly arranged at the two ends of the supporting wheel seat 9, and two supporting wheels 11 are symmetrically and rotatably arranged at the upper part of the supporting wheel seat 9.

In this embodiment, a hydraulic jack 12 is fixedly mounted on the upper portion of the mounting seat 8, a telescopic end of the hydraulic jack 12 is fixedly connected with the bottom of the corresponding support wheel seat 9, and the height of the support wheel seat 9 can be adaptively adjusted through the hydraulic jack 12.

Two sliding rods 3 on the same frame body 1 are symmetrically and slidingly provided with two third sliding sleeves 13 matched with the two sliding rods 13 above the two second sliding sleeves 10, and a horizontal connecting plate 14 is fixedly arranged between the two third sliding sleeves 13. Two limit wheel seats 15 are symmetrically arranged at the lower part of the connecting plate 14, and each limit wheel seat 15 is respectively and rotatably provided with a limit wheel 16.

In this embodiment, two through holes are symmetrically formed on the connecting plate 14, a connecting rod 17 adapted to the through holes is vertically slidably mounted in each through hole, and each limit wheel seat 15 is fixedly connected with the lower end of the corresponding connecting rod 17. A spring 18 is sleeved at the position of each connecting rod 17 between the connecting plate 14 and the limiting wheel seat 15, and a limiting head 19 with the outer diameter larger than the inner diameter of the through hole is fixedly arranged at the upper end of each connecting rod 17.
