Problems solved by technology

The two are fixed and sealed by welding. At present, the welding method on the market is relatively complicated, and it is welded by manual equipment, which has low efficiency. In addition, the inner wall of the connecting pipe is melted with a hot-melt pipe during welding, and the melted part of the connecting pipe will be Adhesion on the outer wall of the hot-melt pipe, when the hot-melt pipe is separated from the connecting pipe, it will drive the melted part of the connecting pipe to fly out, resulting in a decrease in the thickness of the connecting pipe and weak welding

Embodiment 1

[0028]The main pipe does not move, and the welding device moves horizontally relative to the main pipe. A transmission mechanism is provided on the base 3. The transmission mechanism includes a servo motor, a transmission rod, a hub and a third bevel gear. The third bevel gear is sleeved on the transmission shaft. The hub is provided with two One is respectively installed on the two ends of the transmission rod, and rolls on the guide rail, the output shaft of the servo motor is connected with the fourth bevel gear, and the third gear meshes with the fourth bevel gear. The rotation of the driver motor is transmitted to the wheel hub through the transmission rod, so that the wheel hub rolls on the track 2, driving the clamping mechanism and the hot-melt mechanism to move horizontally, which is simple and convenient, and the transmission is accurate and stable. Adding spacers between them can adjust the balance of the track 2.

Embodiment 2

[0030] The welding mechanism does not move, and the main pipe moves horizontally relative to the welding device. Rollers are provided on the inner sides of the two branches of the bracket 1 used to support the main pipe to reduce the friction between the main pipe and the bracket 1, facilitate the movement of the main pipe and avoid scratching of the bracket 1 Injure the supervisor, set a power mechanism at one end of the supervisor to move it, it includes the first shaft, the second shaft, a gear box and a stepping motor, the first shaft and the second shaft are arranged in parallel, and are not located on the upper and lower sides of the supervisor One end of the first rotating shaft is coaxially fixedly connected with a driven wheel, one end of the second rotating shaft is coaxially fixedly connected with a driving wheel, the driving wheel and the driven wheel are driven by a belt, and the main shaft of the stepping motor and the input shaft of the gearbox are connected throu...

Embodiment 3

[0037] The rotating assembly includes a cylinder, a chain, a gear and an extension spring. The cylinder is connected to the fixed plate 6, the piston rod of the cylinder is fixedly connected to one end of the chain, the other end of the chain is fixedly connected to the extension spring, and the other end of the extension spring is connected to the fixed plate 6. To connect, the gear is sleeved outside the hot-melt pipe 5 and meshed with the chain, and the hot-melt pipe 5 is turned forward and backward through the cooperation of the cylinder and the tension spring.

[0038] A welding method, the left splint 7 does not move, the right splint 8 is separated from the left splint 7, after the auxiliary pipe is installed in the clamping hole, the left splint 7 and the right splint 8 are spliced ​​and fixed; the hot-melt mechanism moves to the top of the connecting pipe, Put the bottom end of the hot-melt pipe 5 in the connecting pipe for 2s~5s, move the clamping mechanism down and s...

Abstract

The invention discloses a petroleum pipeline and welding equipment and a welding method for the petroleum pipeline. The petroleum pipeline is prepared by the following raw materials: 55-58 parts of nitrile rubber, 8-10 parts of fluororubber, 13-15 parts of polyurethane resin, 6-8 parts of polytetrafluoroethylene, 2.5-4 parts of sodium methyl silicate, 0.5-1 parts of graphene, 1-2 parts of titaniumdioxide, and 0.5-2 parts of sodium alkyl sulfonate. The welding equipment comprises Y-shaped pipeline support frames, tracks and a welding apparatus, the welding apparatus comprises a base, a hot melt pipe, a fixing plate, a left clamping plate, a right clamping plate and a rotating component, the left clamping plate and the right clamping plate are spliced for fixing an auxiliary pipe, the bottom end of the hot melt pipe is placed in a connecting pipe for 2 s-5 s, the auxiliary pipe is moved down and sleeved at the top end of the hot melt pipe for 2 s-5 s, the rotating component makes the hot melt pipe rotate, simultaneously the auxiliary pipe moves up together with the hot melt pipe, after the connecting pipe is separated from the hot melt pipe, the hot melt pipe does not move, the auxiliary pipe continues to rise, after the auxiliary pipe is separated from the hot melt pipe, the hot melt pipe stops rotating, the hot melt pipe retreats, and the auxiliary pipe is moved down and placed into the connecting pipe for 5 s-10 s to complete the welding. The welding method is simple and convenient.

Description

technical field [0001] The present invention relates to welding equipment, more specifically, it relates to an oil pipeline, welding equipment and welding method for the oil pipeline. Background technique [0002] In special occasions, it is necessary to install an auxiliary pipe on the main pipe to divert the flow. The main pipe is provided with a connecting pipe, and one end of the auxiliary pipe is inserted into the connecting pipe. The two are fixed and sealed by welding. At present, the welding method on the market is relatively complicated, and it is welded by manual equipment, which has low efficiency. In addition, the inner wall of the connecting pipe is melted with a hot-melt pipe during welding, and the melted part of the connecting pipe will be Adhesion on the outer wall of the hot-melt pipe, when the hot-melt pipe is separated from the connecting pipe, it will drive the melted part of the connecting pipe to fly out, resulting in the reduction of the thickness of ...
