DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figure 1-4The utility model provides a technical solution: a pay-off stand for metro electromechanical construction, comprising two pay-off stand bodies 1; in order to solve the problem of maintaining stability when the wire roller is paying off and improving the pay-off efficiency, a plurality of adjustment mechanisms 2 are provided in the pay-off stand body 1, and symmetrical guide blocks 3 are installed at both ends of the pay-off stand body 1; the adjustment mechanism 2 comprises a slide rail 21 provided in the pay-off stand body 1, a slider 22 is slidably installed in the slide rail 21, a rotating shaft 23 is installed at one end of the slider 22, and a connecting rod is provided in the rotating shaft 23 Tube 24, a fixed block 25 is installed in the connecting tube 24, and stacked springs 26 are installed at both ends of the fixed block 25. A bearing column 27 is installed on the side of the rotating shaft 23. A symmetrical connecting block 29 is installed on the side of the wire-paying frame body 1. A plurality of limiting columns 28 are installed at one end of the connecting block 29. A plurality of limiting holes 8 are opened on the side of the wire-paying frame body 1. The limiting holes 8 and the limiting columns 28 are adapted. A wire roller body 11 is placed between the two wire-paying frame bodies 1, and both ends of the wire roller body 11 are placed on the side of the bearing column 27. The connecting The tube 24 is installed in the rotating shaft 23, and the bearing column 27 is rotatably installed on the side of the rotating shaft 23. The distance between the two bearing columns 27 is adjusted by the connecting block 29 on the side of the wire pay-off frame body 1. Pulling the handles 10 at both ends drives the spring 26 to stretch, and the limit column 28 is separated from the limit hole 8, canceling the limit on the bearing column 27. Pushing the bearing column 27 drives the slider 22 to slide in the slide rail 21, aligning the limit column 28 with the limit hole 8 whose position needs to be adjusted. After releasing the handle 10, the spring 26 contracts and drives the limit column 28 to slide. Insert it into the limiting hole 8, fix the supporting column 27, adjust the distance between the two supporting columns 27 in the pay-off frame body 1 according to the diameters of the two ends of the line roller body 11, and after the adjustment is completed, push the line roller body 11 onto the pay-off frame body 1 from the guiding slope 4 at one end of the guide block 3. The two supporting columns 27 support the two ends of the line roller body 11. At this time, the line wound on the line roller body 11 is paid off, and the supporting columns 27 rotate in the pay-off frame body 1, which makes it easier for the operator to pay off the line, thereby improving the operator's pay-off efficiency.

[0023] The working principle is as follows: when we need to use the pay-off stand main body 1 to pay off the wire roller main body 11, take out the two pay-off stand main bodies 1, turn one end of the threaded rod 6 through the through-hole 5 on the side of the guide block 3, and the abutment block 9 abuts against the side of the guide block 3. The threaded sleeve 7 is installed through the other end of the threaded rod 6, and the two pay-off stand main bodies 1 are connected through the two threaded rods 6. The distance between the two pay-off stand main bodies 1 is adjusted by rotating the threaded sleeve 7, and the distance between the two bearing columns 27 is adjusted through the connecting block 29 on the side of the pay-off stand main body 1. The handles 10 at both ends are pulled to drive the spring 26 to stretch, and the limiting column 28 is separated from the limiting hole 8, thereby canceling the limit on the bearing column 27, and pushing the bearing column 27 to drive The slider 22 slides in the slide rail 21, aligning the limit column 28 with the limit hole 8 that needs to be adjusted. After releasing the grip 10, the spring 26 contracts to drive the limit column 28 to slide into the limit hole 8, fixing the bearing column 27, and adjusting the distance between the two bearing columns 27 in the pay-off frame body 1 according to the diameters of the two ends of the line roller body 11. After the adjustment is completed, the line roller body 11 is pushed onto the pay-off frame body 1 from the guiding inclined surface 4 at one end of the guide block 3. The two bearing columns 27 support the two ends of the line roller body 11. At this time, the line wound on the line roller body 11 is paid out, and the bearing column 27 rotates in the pay-off frame body 1, which makes it easier for the operator to pay out the line, thereby improving the operator's pay-off efficiency.

[0024] Example 2: Figure 1 and 2 As shown, a guiding slope 4 is provided at one end of the guide block 3, a through hole 5 is provided on the side of the guide block 3, a threaded rod 6 is installed in the through hole 5, one end of the threaded rod 6 is threadedly connected to a threaded sleeve 7, and a stop block 9 is installed at the other end. One end of the threaded rod 6 is slidably installed in the through hole 5, and the other ends of the two threaded rods 6 are connected by a threaded sleeve 7. The two pay-off frame bodies 1 are taken out, and one end of the threaded rod 6 is turned in through the through hole 5 on the side of the guide block 3. The stop block 9 is abutted against the side of the guide block 3, and the threaded sleeve 7 is installed through the other end of the threaded rod 6. The two pay-off frame bodies 1 are connected through the two threaded rods 6. The distance between the two pay-off frame bodies 1 is adjusted by rotating the threaded sleeve 7 to improve the applicability of the device. The remaining features are the same as those in Example 1.
