Detailed Description

The technical solution of the present application will be described in further detail below with reference to the accompanying drawings.

Referring to fig. 1, a welding positioning tool disclosed in an embodiment of the present application is composed of a workbench 11, a first fixing ring 12, a rotating ring 13, a first fixing device 14, a roller set 15, a second fixing ring 16, a second fixing device 17, and the like, and specifically, the workbench 11 is placed on the ground to provide a stable working environment, and when the ground is uneven, leveling needs to be performed by using a sizing block and the like.

Referring to fig. 2 and 3, the first fixing ring 12 and the second fixing ring 16 are both disposed on the worktable 11, the two fixing rings are coaxial, and the first fixing ring 12 and the second fixing ring 16 are respectively used for limiting two ends of the pipeline, so that the pipeline can be adjusted in posture as required.

In some possible implementations, the first and

second fixing rings

12 and 16 are welded to the table 11.

The rotating ring 13 is rotatably connected to the first stationary ring 12, and has an outer diameter smaller than an inner diameter of the first stationary ring 12, and one end of the rotating ring 13 is protruded from the first stationary ring 12. A plurality of first fixing means 14 are mounted on the end of the rotating ring 13 protruding from the first fixing ring 12, and the first fixing means 14 are used for applying pressure or thrust to the pipe passing through the rotating ring 13 to adjust the posture of the pipe.

It will be appreciated that the attitude of the pipe after it has passed through the rotating ring 13 can be adjusted as follows: the first fixing device 14 can complete several kinds of ascending, descending, leftward and rightward operations, and the rotation is realized by the rotating ring 13.

In some possible implementations, the first fixing device 14 uses a large diameter bolt or screw.

It will also be appreciated that where two pipes are butted together, limited by the flatness of the weld faces, there are situations where it is necessary to rotate the pipes, and this can be done by rotating the ring 13.

The roller set 15 is installed on the workbench 11 and functions to convert the dynamic friction force between the pipeline and the workbench 11 into static friction force and reduce the resistance when installing the pipeline.

Referring to fig. 1, it will be appreciated that when installing a pipe, it is necessary to pass one end of the pipe through the second stationary ring 16 and the rotating ring 13 in sequence, with a distance between the two rings, and it is laborious to advance the pipe by means of lifting and pushing. After the roller set 15 is added, one end of the pipeline can be pressed on the roller set 15 after passing through the second fixing ring 16, and then extends into the first fixing ring 12 in a pushing manner.

It should be understood that when the length of the pipeline is longer, the two ends of the pipeline need to be adjusted simultaneously, so that the abutting surfaces of the two pipelines can be aligned, therefore, the second fixing rings 16 are uniformly provided with a plurality of second fixing devices 17, and one ends of the second fixing devices 17 penetrating through the second fixing rings 16 can be abutted against the pipelines.

In some possible implementations, the second fixing means 17 uses a large diameter bolt or screw.

On the whole, the welding positioning tool provided by the embodiment of the application can adjust the postures of the pipelines, so that the welding surfaces of the two pipelines can be aligned, the preparation time before welding is reduced, the welding time can be shortened, and the working efficiency is improved.

As a specific embodiment of the welding positioning tool provided by the application, the number of the first fixing devices 14 is three or more, because when the number of the first fixing devices 14 is one or two, the pipe is easily displaced in the rotating ring 13, and if this occurs in the welding process, the welding failure is directly caused.

Further, the number of the first fixing devices 14 is three.

As a specific embodiment of the welding positioning tool provided in the application, the number of the second fixing devices 17 is three or more, because when the number of the second fixing devices 17 is one or two, the pipe is easily displaced in the second fixing ring 16, and if such a situation occurs in the welding process, the welding failure is directly caused.

Further, the number of the second fixing means 17 is three.

Referring to fig. 1 and fig. 2, as a specific embodiment of the welding positioning tool provided in the application, a contact hemisphere 141 is additionally installed at the working end of the first fixing device 14, and the contact hemisphere 141 functions to reduce the contact area between the first fixing device 14 and the pipeline, so as to facilitate posture adjustment of the pipeline.

It will be understood that for the attitude adjustment of the pipe, it is generally divided into two stages, the first stage being the distance between the welded faces, in which the adjustment is to push the pipe forward or backward in the direction of its own axis; the second stage is to adjust the parallelism between the welded surfaces, in which the second fixture 17 needs to be rotated, and at this time, the pipe starts to swing, which reduces the contact area between the pipe and the first fixture 14, and can reduce the resistance of the pipe when swinging.

Referring to fig. 4, as a specific embodiment of the welding positioning tool, the roller set 15 is composed of a lifting device 151, a base 152 and a roller 153, the lifting device 151 is fixedly installed on the worktable 11, the base 152 is fixed on the working end of the lifting device 151, and the roller 153 is installed on the base 152.

The lifting device 151 is used for pushing the base 152 to move towards and away from the worktable 11, and specifically, the roller 153 is suitably lifted to support the pipeline when moving the pipeline into and out; during adjustment, the roller 153 is lowered appropriately and out of contact with the pipe; during welding, the roller 153 needs to be raised into contact with the pipe but only held in contact.

Further, the number of the rollers 153 is increased to two, and the two rollers 153 are symmetrically arranged on the base 152, and the axes thereof are located in the same plane and intersect with each other. With reference to the duct, the two rollers 153 are respectively located at two sides of the duct instead of the bottom, so that the rollers 153 can play a role of guiding while supporting the duct.

The embodiments of the present invention are preferred embodiments of the present application, and the scope of protection of the present application is not limited by the embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
