Description

Technical Field

[0001] The utility model belongs to the technical field related to pipeline processing, and particularly relates to an alignment welding device for a gas supply pipeline. Background Art

[0002] The gas supply pipeline is a pipeline that transports gas from the mining site or processing plant to the urban gas distribution center or industrial enterprise users. At the same time, the gas supply pipeline can be divided into three types according to its purpose: gas gathering pipeline, gas transmission pipeline, and gas distribution pipeline. Therefore, when it is necessary to weld multiple gas supply pipelines, it is necessary to use the corresponding alignment welding device to align and connect the two gas supply pipelines.

[0003] However, when using the alignment welding device to butt-joint two gas supply pipes, the gas supply pipes cannot be quickly fixed and limited, so the gas supply pipes are prone to position deviation during the welding process, resulting in welding position deviation. At the same time, when the gas supply pipes need to be circle welded, since the two gas supply pipes cannot be driven to rotate synchronously, multiple people are required to cooperate during welding, which reduces the welding efficiency. To this end, we provide a gas supply pipe alignment welding device to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide an air supply pipeline alignment welding device, which controls the relative movement of two abutment plates on the left and right sides so that the two abutment plates can clamp the air supply pipeline to ensure stable welding. At the same time, when the rotating ring is rotated, the two air supply pipelines can be controlled to rotate synchronously through the use of a linkage tooth plate, thereby improving welding efficiency.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model is an air supply pipeline alignment welding device, comprising two positioning plates which are symmetrically arranged front to back; rotating rings are arranged on opposite end faces of the two positioning plates, semicircular T-shaped openings are opened on opposite end faces of the two positioning plates, T-shaped rings which are used for rotation with the semicircular T-shaped openings are fixed to the end faces of the rotating rings relative to the positioning plates, toothed rings which are sleeved on the circumferential sides of the positioning plates are arranged on the opposite end faces of the two rotating rings, linked toothed plates which mesh with the toothed rings are arranged directly below the toothed rings, abutment plates are arranged on the left and right parts of the inner side walls of the rotating rings, a plurality of arc openings which are evenly distributed in an annular shape are penetrated through the inner wall of each positioning plate, and pulleys are arranged inside the arc openings.

[0009] The utility model is further configured that screw holes are penetrated through the inner wall of the rotating ring at positions corresponding to the abutment plates, and screw rods spirally connected to the screw holes are arranged on opposite end surfaces of two abutment plates that are consistent on the left and right sides.

[0010] The utility model is further configured that a T-shaped hole is provided at a position of the abutting plate relative to the screw rod, and a T-shaped round block which is used for rotationally cooperating with the T-shaped hole is fixed on the end surface of the screw rod at the rotating ring.

[0011] The utility model is further configured that the end faces of the screw rods passing through the screw holes are fixed with rotating plates, and the outer side wall of the rotating ring is fixedly connected to the gear ring through a connecting strip.

[0012] The utility model is further configured that positioning holes are penetrated through the inner side walls of the rotating ring located above and below the screw hole, and positioning rods that slide through the inner positions of the positioning holes are fixed to the end faces of the abutment plates that are consistent on the left and right sides.

At this time, the abutment plate is moved so that the two abutment plates inside each rotating ring clamp the air supply pipe, thereby ensuring stable welding and avoiding position deviation of the air supply pipe.

[0016] When the utility model is in use, the rotating ring will drive the two abutment plates to rotate, and thereby drive the corresponding air supply pipe to rotate inside the positioning plate, and at the same time drive the gear ring connected thereto to rotate, and then drive the linkage gear plate to rotate, thereby driving the rotating ring on the other side to rotate, and causing it to drive the air supply pipe to rotate, so that the two air supply pipes can rotate synchronously, thereby improving the welding efficiency between the two air supply pipes.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] For example, see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6The utility model is a gas supply pipeline alignment welding device, which controls the relative movement of two abutment plates 4 on the left and right sides so that the two abutment plates 4 will clamp the gas supply pipeline to ensure stable welding. At the same time, when the rotating ring 2 is rotated, the linkage tooth plate 3 can be used to control the two gas supply pipelines to rotate synchronously, thereby improving welding efficiency.

[0029] Specifically, two positioning plates 1 are arranged symmetrically front and back; the opposite end faces of the two positioning plates 1 are provided with rotating rings 2, and the opposite end faces of the two positioning plates 1 are provided with semicircular T-shaped openings 101. The end faces of the rotating rings 2 relative to the positioning plates 1 are fixed with T-shaped rings 202 for rotation with the semicircular T-shaped openings 101. Since the T-shaped rings 202 are in the semicircular T-shaped openings 101, when the rotating rings 2 rotate, the rotating rings 2 will drive the T-shaped rings 202 to rotate inside the semicircular T-shaped openings 101, thereby ensuring the stability of the assembly connection between the rotating rings 2 and the positioning plates 1;

[0030] The opposite end faces of the two rotating rings 2 are provided with a gear ring 201 which is sleeved on the circumferential side of the positioning plate 1, and a linkage gear plate 3 which meshes with the gear ring 201 is provided directly below the gear ring 201. Abutment plates 4 are provided on the left and right parts of the inner wall of the rotating ring 2. The inner wall of each positioning plate 1 is penetrated by a plurality of arc openings 102 which are evenly distributed in a ring shape, and a pulley 104 is provided inside the arc opening 102.

[0031] The operation process of this embodiment is as follows: through the setting and use of the above-mentioned structure, when it is necessary to weld the two air supply pipes, the two air supply pipes are passed through the internal positions of the two rotating rings 2, so that the two air supply pipes will be respectively located at the inner positions of the positioning plate 1, and the two air supply pipes are abutted against each other, so that the gap between the two is located at the position between the two positioning plates 1. At this time, by moving the abutment plate 4, the two abutment plates 4 inside each rotating ring 2 clamp the air supply pipe. At the same time, in order to be able to synchronously drive the two air supply pipes to rotate synchronously, the user can control the rotating ring 2 to rotate, and then the rotating ring 2 will drive the two abutment plates 4 to rotate, and thereby drive the corresponding air supply pipe to rotate inside the positioning plate 1, and at the same time drive the gear ring 201 connected thereto to rotate, and then drive the linkage gear plate 3 to rotate, thereby driving the rotating ring 2 on the other side to rotate, so that it drives the air supply pipe to rotate, so that the two air supply pipes can rotate synchronously.

[0032] For example 2, please refer to Figure 3 and Figure 6 On the basis of the first embodiment, the pulley 104 is used to lower the position between the air supply pipeline and the positioning plate 1, thereby improving the rotation efficiency of the air supply pipeline.

[0033] Specifically, a connecting base frame 5 is provided directly below the two positioning plates 1, and the connecting base frame 5 is fixedly connected to the positioning plates 1, a rotating rod 301 is fixed at the position between the two linkage tooth plates 3, and the linkage tooth plates 3 are located at the front and rear positions of the connecting base frame 5, the rotating rod 301 is rotatably connected to the connecting base frame 5 through the provided bearing 501, and an axle rod 103 is fixed between the front and rear end surfaces inside the arc opening 102, and the pulley 104 is rotatably sleeved on the corresponding axle rod 103.

[0034] The operation process of this embodiment is: the two linked tooth plates 3 are assembled together through the rotating rod 301, so that the two linked tooth plates 3 can drive the corresponding tooth rings 201 to rotate, and at the same time, the air supply pipeline is located at the inner side of the positioning plate 1, so that the air supply pipeline can be connected to the pulley 104. Therefore, when the rotating ring 2 drives the air supply pipeline to rotate, the air supply pipeline will drive the pulley 104 to rotate at the internal position of the arc mouth 102, thereby lowering the position between the air supply pipeline and the positioning plate 1, and improving the rotation efficiency of the air supply pipeline.

[0035] For example 3, please refer to Figure 2 , Figure 4 and Figure 5 On the basis of the first embodiment, the movement of the abutment plate 4 can be positioned by using the T-shaped round block 403 in conjunction with the T-shaped hole 401 and the positioning rod 404 in conjunction with the positioning hole 205 .

[0036] Specifically, screw holes 204 are penetrated at the positions of the inner wall of the rotating ring 2 corresponding to the abutment plates 4, and screw rods 402 spirally connected to the screw holes 204 are arranged on the opposite end faces of the two abutment plates 4 on the left and right sides. T-shaped holes 401 are opened at the positions of the abutment plates 4 relative to the screw rods 402, and T-shaped round blocks 403 for rotation with the T-shaped holes 401 are fixed on the end faces of the screw rods 402 on the rotating ring 2, and rotating plates 405 are fixed on the end faces of the screw rods 402 passing through the screw holes 204. The outer wall of the rotating ring 2 is fixedly connected to the gear ring 201 by the connecting strips 203, and the inner wall of the rotating ring 2 located above and below the screw holes 204 is penetrated by positioning holes 205, and the end faces of the abutment plates 4 on the left and right sides are fixed with positioning rods 404 that slide through the inner positions of the positioning holes 205.

[0037] The operation process of this embodiment is: when it is necessary to control the abutment plate 4 to clamp the air supply pipe at the inner position of the rotating ring 2, the rotating plate 405 can be rotated, thereby the rotating plate 405 will drive the screw 402 to rotate inside the screw hole 204, and then drive the T-shaped round block 403 to rotate inside the T-shaped hole 401, so that the screw 402 will drive the abutment plate 4 to move, and ensure that the abutment plate 4 will not rotate with the screw 402. At the same time, when the abutment plate 4 moves, it will drive the positioning rod 404 to slide in the internal position of the positioning hole 205, and limit the positioning rod 404 through the positioning hole 205, so as to ensure the stability of the movement of the abutment plate 4.
