Description

Technical Field

[0001] The utility model belongs to the technical field of gas pipeline docking, in particular to a gas pipeline docking auxiliary device. Background Art

[0002] Gas pipelines are generally connected by welding or threaded connections. Welding is mostly used for gas pipeline connection in engineering projects. Gas pipeline welding mostly adopts the method of spot welding and alignment before welding. When welding, sand is mostly placed at the bottom of the gas pipeline to support the gas pipeline and prevent the gas pipeline from shifting during welding and causing breakage at the joint.

[0003] At present, most gas pipelines are connected by welding. When connecting the gas pipelines, due to the heavy weight of the gas pipelines, the sand at the bottom of the gas pipelines may settle, and then cause the gas pipelines to break at the connection point. Therefore, a gas pipeline connection auxiliary device is needed. The gas pipeline can be supported by a supporting structure to prevent the sand at the bottom of the pipeline from settling and causing the gas pipelines to break at the connection point, thereby ensuring the stability of the gas pipeline connection. Utility Model Content

[0004] The purpose of the utility model is to provide a gas pipeline docking auxiliary device, which can support the gas pipeline through a supporting structure, avoid the settlement of sand at the bottom of the pipeline and cause breakage at the gas pipeline docking point, thereby ensuring the stability of the gas pipeline docking, so as to solve the above-mentioned background technical problems.

[0005] The technical solution of the utility model for solving the above-mentioned technical problems is as follows: a gas pipeline docking auxiliary device, which includes a transfer frame, a support plate is provided on the top of the transfer frame, and four symmetrical limit rods are welded on the bottom of the support plate, the limit rods pass through the transfer frame and are slidably connected to the transfer frame, and a slide groove 1 is provided on the top of the transfer frame, and the inner cavity of the slide groove 1 is slidably connected with a slider, and the inner cavity of the slide groove 1 is welded with two symmetrical slide rods, and the slide rods pass through the slider and are slidably connected to the slider, and the inner cavity of the slide groove 1 is rotatably connected with a threaded rod 1, and the threaded rod 1 passes through the slider and is threadedly connected to the slider, and the top of the slider is rotatably connected with two symmetrical connecting rods, and the other end of the connecting rod is rotatably connected to the bottom of the support plate, and the right side of the threaded rod 1 passes through the outside of the transfer frame and is fixedly connected to a turning handle.

[0006] Preferably, two symmetrical limiting plates are provided on the top of the support plate, a fixing block is welded on the bottom of the limiting plate, and two symmetrical chute 2 are opened on the top of the support plate, and the fixing block is adapted to the chute 2.

[0007] Preferably, the inner cavity of the second slide groove is rotatably connected to a threaded rod 2, the threaded rod 2 passes through the fixed block and is threadedly connected to the fixed block, and the opposite sides of the two threaded rods 2 pass through the outside of the second slide groove and are fixedly connected to a torsion block.

[0008] Preferably, two symmetrical limiting bars are welded to the bottom of the limiting plate, and four symmetrical limiting grooves are opened on the top of the supporting plate, and the limiting bars are adapted to the limiting grooves.

[0009] Preferably, the front and back sides of the transfer rack are rotatably connected to two symmetrical rotating wheels, the limiting plate is L-shaped, and two symmetrical triangular support plates are welded to the top of the limiting plate.

[0010] Preferably, the bottom of the limiting plate fits in with the top of the supporting plate, the limiting bar is cylindrical, and two symmetrical fixing rods are fixedly connected to the surface of the torsion block.

[0011] The beneficial effects of the utility model are:

[0012] 1. The utility model pushes the transfer frame to the bottom of the gas pipeline, rotates the handle, and causes the threaded rod and the slider to move in a threaded manner. The slider is limited by the sliding rod, so that the slider pushes the support plate through the connecting rod to move. The limit rod is limited so that the support plate moves upward and fits the bottom of the gas pipeline. The gas pipeline can be supported by the support structure, thereby preventing the sand at the bottom of the pipeline from settling and causing the gas pipeline to break at the joint, thereby ensuring the stability of the gas pipeline joint.

[0013] 2. The utility model cooperates with the limit plate, the fixed block, the second slide groove, the second threaded rod, the limit bar and the limit groove. When the support plate supports the gas pipeline, the torsion block is rotated to slide the limit plate toward the gas pipeline, so that the limit plate limits the gas pipeline, avoids the gas pipeline from deflecting on the top of the support plate, and increases the stability of the gas pipeline on the top of the support plate.

When the plate 2 supports the gas pipeline, the torsion block 14 is rotated to make the limit plate 10 slide in the direction of the gas pipeline, so that the limit plate 10 limits the gas pipeline, preventing the gas pipeline from deviating at the top of the support plate 2, thereby increasing the stability of the gas pipeline at the top of the support plate 2.

[0026] Working principle: When the present invention is used, the user pushes the transfer rack 1 to the bottom of the gas pipeline and turns the handle 9 to make the threaded rod 7 and the slider 5 move in a threaded manner. Through the limitation of the slide rod 6, the slider 5 slides in the direction away from the handle 9, so that the slider 5 pushes the support plate 2 to move through the connecting rod 8. Through the limitation of the limiting rod 3, the support plate 2 moves upward and fits the bottom of the gas pipeline to support the gas pipeline, avoiding the settlement of sand at the bottom of the pipeline and causing the gas pipeline to break at the joint, thereby ensuring the stability of the gas pipeline joint. When the support plate 2 supports the gas pipeline, the torsion block 14 is rotated to make the limiting plate 10 slide in the direction of the gas pipeline, so that the limiting plate 10 limits the gas pipeline, avoiding the gas pipeline from deviating at the top of the support plate 2, thereby increasing the stability of the gas pipeline on the top of the support plate 2.
