The pushing mechanism 7 includes a jack, which can be disposed on the connecting plate 46, and the two ends of the jack are respectively against the pipe rack support pier 45 and the slide groove 61.

[0053] Embodiment 2:

[0054] like Figures 6 to 8 As shown, it also includes a connecting mechanism, the number of pipeline fixing mechanisms is multiple and each two pipeline fixing mechanisms form a group and are symmetrically arranged on both sides of the valve regulating mechanism, and each group of two pipeline fixing mechanisms is connected by a connecting mechanism, and the connecting mechanism can be retracted to push. Each connecting mechanism includes a connector 81 and two screw rods 82 threadedly connected to the connector 81, the two screw rods 82 are designed to be colinear in the axis and the thread rotation directions are opposite, and each screw rod 82 is connected to the corresponding pipeline fixing mechanism.

[0055] The specific working process of this embodiment is as follows:

[0056] This embodiment is an assembled connection structure, which can be transported to the installation site in pieces and then assembled, making it easy to move and transport. The length of the chute 61 and the pipe support 42 can be adjusted and selected according to the on-site installation environment. During assembly, the connection can be reinforced by welding. After the device is assembled, the valve 2 is installed on the valve support 52.

[0057] Move the mounting frame 3 to the predetermined installation position of the valve 2. To improve stability and safety, the mounting frame 3 can be connected to the surrounding buildings for reinforcement. Install the two pipe connecting components 41 on the pipes 1 on both sides of the valve 2 respectively. In this embodiment, the multiple pipe clamps of each pipe connecting component 41 can be tightly clamped outside the pipe 1. Adjust the length of the telescopic component 4 on each side to fix the corresponding connecting plate 46 on the relative pipe support 42. During the adjustment process, the connecting plate 46 can slide on the pipe support 42. By turning the nut 43, the length of the fixed screw 44 extending out of the pipe support pier 45 can be adjusted. Connect the two pipe connecting components 41 to the connecting mechanism to form a whole.

[0058] According to the size of the valve 2, the pipe 1 is cut to form a pipe opening that can be connected to the pipe 1. The pipe opening for connection can be supported and fixed by the pipe fixing mechanism. One end of the jack is pressed against the slide 61 and the other end is pressed against the pipe support pier 45. At the same time, the length of the screw rod 82 extending out of the connector 81 and the jack are adjusted to make the pipe fixing mechanism slightly move away from each other to fine-tune the distance between the two relatively set pipe openings, so as to ensure that the valve 2 can be smoothly installed between the two relatively set pipe openings and avoid affecting the connection effect between the valve 2 and the pipe 1 due to the excessive distance between the two relatively set pipe openings after adjustment. The connection mechanism can work together with the push mechanism 7 to ensure the installation effect of the valve 2. The position of the moving wheel 31 is adjusted along the length direction of the slide 61, and the valve 2 is transported to the installation location and corresponds to the pipe opening of the connection end of the pipe 1. The lifting platform 51 is adjusted to adjust the height of the valve 2 so that the center elevation of the valve 2 is consistent with the elevation of the pipe opening of the connection end to be welded.

[0059] Synchronously adjust the length of the jack and the connecting mechanism to slowly move the pipeline fixing mechanism toward the valve 2 until the distance between the flanges on both sides of the valve 2 and the corresponding connecting end pipe openings reaches the installation requirement, weld and fix the flange of the valve 2 to the pipe opening of the connecting end of the pipeline 1, and after completing the connection between the valve 2 and the pipe opening, adjust the height of the lifting platform 51 to move the valve support 52 downward, remove multiple pipe clamps and move the auxiliary valve installation device out of the working area.

[0060] This embodiment can be used to fix the pipeline 1, and can also fine-tune the distance between the two pipe openings formed after cutting, so as to ensure the installation efficiency and quality of the valve 2; this embodiment can also be extended to fine-tune the distance between a pipe opening and the valve 2 and fix the pipe opening. The multi-telescopic structure can be better adapted to narrow or complex installation environments, and the flexible adjustment can improve the installation efficiency and facilitate the rapid installation and removal of the valve 2; the connection mechanism and the push mechanism 7 work together to ensure the installation accuracy.

[0061] This embodiment can replace the traditional construction machinery with a chain fall, and can flexibly adjust the installation direction according to the valve position, quickly fix it in place, create construction conditions for the welding of the valve group, and improve construction efficiency; reduce the number of construction machinery and the number of workers, and reduce installation costs; the device occupies a small space and can be better applied to small or complex construction environments. It is easy to use, improves work efficiency, shortens construction period, has low manufacturing costs, and can be used for multiple projects, which is convenient and fast.

[0062] The embodiments of the present invention are described in detail above, but the contents described are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
