Problems solved by technology

[0002] Oil pipelines are affected by the environment during transportation, and the transportation direction of the pipeline often needs to be changed, so a transfer pipe is used for connection. Before connecting the pipe, it needs to be cut according to the angle. At present, the existing welding equipment on the market has Too single, only simple welding, cutting and connecting need to use other equipment, the operation is more inconvenient

Embodiment 1

[0023] The jacket includes a lower jacket and an upper jacket. The upper jacket and the lower jacket are spliced ​​to form a round hole for the straight pipe to be put in. The straight pipe moving mechanism is set as the No. 1 hydraulic cylinder. The cylinder body of the No. 1 hydraulic cylinder and the straight pipe The support is fixedly connected, the piston rod is fixedly connected with the lower jacket, and the lower jacket is slidably connected with the straight pipe support.

Embodiment 2

[0025] The jacket includes a fixed jacket and a semicircular support jacket. The fixed jacket includes a lower jacket and an upper jacket. The upper jacket and the lower jacket are spliced ​​to form a round hole for straight pipes. The lower jacket is fixed on On the straight pipe support, the straight pipe moving mechanism includes a No. 1 hydraulic cylinder, a slide block and a slide table, the slide table is fixedly connected along the length direction of the straight pipe support, the slide block is slidingly connected with the slide table, and the support jacket is fixed on the slide block.

[0026] The takeover cutting device 4 includes a support mechanism 41 and a cutting mechanism 42. The support mechanism 41 includes a cutting bracket, No. 2 hydraulic cylinder, No. 3 hydraulic cylinder, and a support seat. The cutting bracket is set to an L shape and is made of triangle steel welding. Including the bottom plate and the vertical plate, the bottom plate is placed on the ...

Abstract

The invention discloses a novel petroleum pipeline welding device. The device comprises a stand, a straight pipe moving clamping device, a connecting pipe moving clamping device, a connecting pipe cutting device and a lifting device, wherein the connecting pipe moving clamping device, comprising a straight pipe support, a clamping sleeve and a straight pipe moving mechanism, is rotated by 30-180 degrees; the straight pipe moving clamping device is matched with the connecting pipe moving clamping device; when the connecting pipe moving clamping device is rotated to be on the same straight lineas the straight pipe moving clamping device, two straight pipes can be welded; when a straight pipe and a connecting pipe are welded, the connecting pipe moving clamping device is rotated to an angleas requirement, and one end of the connecting pipe is cut to form an angle as requirement through the connecting pipe cutting device; the lifting device is used for placing the connecting pipe on a supporting seat or placing the cut connecting pipe from a supporting seat to the connecting pipe supporting frame and can also be used for placing the straight pipe on the straight pipe support. With the adoption of the device, manual carrying is saved, so that both time and force can be saved, and the working efficiency is improved.

Description

technical field [0001] The present invention relates to welding equipment, more specifically, it relates to a new type of oil pipeline welding equipment. Background technique [0002] Oil pipelines are affected by the environment during transportation, and the transportation direction of the pipeline often needs to be changed, so a transfer pipe is used for connection. Before connecting the pipe, it needs to be cut according to the angle. At present, the existing welding equipment on the market has It is too single, and can only be welded simply, and other equipment is required to cut the connection, which is inconvenient to operate. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a new oil pipeline welding equipment with multiple functions of welding and cutting. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] A new type of o...
