[0001] The utility model relates to the technical field of pipe installation, in particular to a pipe installation auxiliary tool, specifically a pipe installation auxiliary device. Background Art

[0002] There are a lot of pipe installation work in the process of pressure vessel manufacturing, which is usually carried out by overhead crane lifting, welding limit blocks and then installing, or manually positioning another person to weld and fix. The work requires the assistance of equipment or multiple people to complete.

[0003] In the above method, a large lifting device such as an overhead crane is used. Since the connecting pipe is generally light in weight, occupying a large lifting device will cause a waste of resources; the installation is carried out after the limit block is welded, and the limit block cannot be quickly disassembled and assembled. After welding and fixing, the welded limit block needs to be removed and repaired, repaired, etc., which increases the workload and increases the working hours; manual positioning installation not only requires two people to operate, but also the person responsible for positioning cannot maintain the same position for a long time during the installation process, which is prone to errors.

[0004] In summary, a pipe installation auxiliary device is needed to fix the pipe, so that a single person can smoothly and smoothly complete the pipe installation work. Summary of the invention

The support frame 1 is a square frame structure with a length greater than a width, and the length of the support frame 1 is smaller than the diameter of the pipe. The threaded support rods 2 are rotatably installed at the same position at both ends of the support frame 1. Specifically, the opposite ends of the two threaded support rods 2 are installed on the two side frame surfaces of the support frame 1 through fixing nuts 4 and limiting nuts 3, that is, hinge holes are opened on the two side frame surfaces, and the threaded support rods 2 are screwed on the limiting nuts 3 and then passed through the hinge holes and fixed with fixing nuts 4. The limiting nuts 3 are fixed to the outside of the support frame 1, and the fixing nuts 4 are fixed to the inside of the support frame 1; further, the end of the threaded support rod 2 close to the support frame 1 is welded with fixing nuts 4 and limiting nuts 3 on the inner and outer sides of the support frame 1.
