Problems solved by technology
The purpose is to solve the problem that the paint layer on the surface of the straight pipe is pulled or squeezed and cracked when the straight pipe is bent in the prior art
[0005] However, in the specific implementation of the above-mentioned patents, it is impossible to achieve targeted grinding of the inner wall. In the actual application of pipelines, since petroleum crude oil often has a high density, it is easy to cause a significant slowdown in the flow rate when passing through the bending parts of the pipeline, and then Affect the transportation of oil

Embodiment
[0031] Example: such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, an auxiliary mechanism for oil pipeline bending of the present invention includes a workbench 1 and a pipe clamp 2 arranged in the middle of the workbench 1. The top of the workbench 1 is provided with an anti-jump mechanism 3, which is used for For anti-jumping in the pipe bending process, the anti-jumping mechanism 3 includes a first base plate 301 and an anti-jumping plate 305 arranged on the top of the first base plate 301. Each end of the anti-jumping plate 305 is provided with a circle center adjustment mechanism 303 and a limit mechanism 307. The anti-jump plate 305 is provided with a first chute 304 on the side opposite to the pipe clamp 2, and the first slide 304 is slidably provided with a first slider 201 fixedly connected to the pipe clamp 2. The workbench 1 There is a pipe grinding mechanism 4 on the side, which is used...

The invention discloses an auxiliary mechanism for petroleum pipeline bending. The auxiliary mechanism comprises a workbench and a pipeline clamping piece arranged in the middle of the workbench. An anti-jumping mechanism is arranged at the top of the workbench, the anti-jumping mechanism is used for preventing jumping in the pipe bending process, and the anti-jumping mechanism comprises a first base plate and an anti-jumping plate arranged at the top of the first base plate. A circle center adjusting mechanism and a limiting mechanism are arranged at each end of the anti-jumping plate, and afirst sliding groove is formed in the side, opposite to the pipeline clamping piece, of the anti-jumping plate. The circle center of the anti-jumping plate can be adjusted in the process of installingthe first base plate through the two circle center adjusting mechanisms, semi-automation is achieved in the process, the error between the adjusted circle center and the rotating axis of the pipelineclamping piece is extremely small, and the problems that in the prior art, the adjusting process is slow, and the error is large are effectively solved; and by arranging the circle center adjusting mechanisms, limiting rods and limiting mechanisms, the anti-jumping plate is well limited and fixed, and the problem that in the prior art, the structural strength is poor is effectively solved.
Description
technical field [0001] The invention relates to a pipeline bending mechanism, in particular to an auxiliary mechanism for petroleum pipeline bending. Background technique [0002] Patent 1: "A Mechanism for Pipe Bending of Petroleum Pipelines" disclosed by China Invention (Application No.: CN201710310465.0), including a shaft, an anti-jump board, a support assembly and a pipe clamp. On the top of the piece, a through groove is provided on the anti-jump plate, and the projected arc of the through groove on the top surface of the pipe clamping piece; a slider is arranged on the pipe clamping piece, and the slider is located in the through groove; The supporting assembly includes a mounting plate, a supporting rod, a beam and a lower pressing rod connected in sequence, the axis of the cross beam is perpendicular to the axis of the supporting rod, the axis of the lower pressing rod is parallel to the axis of the supporting rod, and the lower pressing rod is far away from the axi...
