Problems solved by technology

[0002] The establishment of industrial pipelines involves the connection between pipes. The connection between pipelines is mainly divided into offline prefabricated butt joint and construction process butt joint. During the construction process, the main methods of pipeline butt joint are bolt connection and welding connection. Among them, the welding connection is more difficult. Before welding, the two connecting pipes need to be accurately connected, that is to say, the neutrality must be ensured before welding, so as not to affect the subsequent pipeline connection. At present, there are auxiliary connection devices on the market. Not only the centering effect is poor, but the welding gap of the pipeline after centering is large, which is inconvenient for welding, and the cost is high and the operation is inconvenient

Embodiment 1

[0034] see Figure 1-3 , a butt joint assembly device for industrial pipeline construction, comprising a riser 1, a four-bar platen group 2, a left roller 3, a right roller 4, a pressing and positioning combination 5 and a driving member 6, and the four-bar platen group 2 includes a parallel quad The rod-plate group 21 and the connecting beam 22, the middle part of the parallelogram-plate group 21 is swingably connected to one side of the riser 1, the number of the connecting beams 22 is two and arranged on one side of the parallel-four-bar-plate group 21 and relatively parallel The rotation axes of the four-bar plate group 21 are distributed symmetrically in the circumferential direction. Specifically, the parallel four-bar plate group 21 is composed of a base bar 211, a guide bar 212 and two rotating shafts 213. The middle part of the base bar 211 is connected to the vertical plate 1 by swinging. One end of the two rotating shafts 213 is arranged on the two ends of the base ...

Embodiment 2

[0036] see Figure 4, and the difference from Embodiment 1 is that the middle pressure roller 52 is also provided with a transmission gear 524, and the upper end face of the rectangular frame 523 is fixed at one end with a support plate 5231 that is rotatably connected to the transmission gear 524. The transmission gear 524 and the two middle One end of the roller 521 is meshed, and the rotation speeds of the two middle rollers 521 are different. The outer periphery of the middle roller 521 rotating at a higher speed is provided with a spiral tooth 5211. Specifically, one end of the two middle rollers 521 is respectively fixed with a gear 5212. Different from the number of teeth of gear 2 5213, gear 1 5212 and gear 2 5213, when the device rotates around two pipes with butt joints, the rolling speed of the middle roller 521 corresponding to the smaller number of teeth is higher, and the roller 521 will be opposite to each other. When the connected pipes are rubbed and rotated, ...

Embodiment 3

[0038] see Figure 5 , and the difference from Embodiment 1 is that the driving member 6 is a booster rod structure, one end of the driving member 6 is hinged with the top of the guide plate 11, and one side is fixedly provided with a pry bar 61 used in conjunction with the upper end surface of the positioning plate 51, hold it manually Pressing the rod 511 and the driving member 6 in the opposite direction can replace the oil cylinder, which is suitable for the docking of small-diameter pipes, has low cost, and is labor-saving and convenient to carry.

[0039] Working principle: When in use, connect the driving part 6 of the oil cylinder structure to the external hydraulic oil circuit, and electrically connect the external control box, and the control box provides control commands, and then place the two middle rollers 521 on the fixed pipe to be connected ( When the fixed pipe is in a horizontally divided state), make sure that one end is in a suspended state, the left idler...

Abstract

The invention discloses a butt-joint assembling device for industrial pipeline construction. The butt-joint assembling device for industrial pipeline construction comprises a vertical plate, a four-rod pressing plate set, a left carrier roller, a right carrier roller, a pressing positioning assembly and a driving piece. According to the device, the vertical plate is arranged, the four-rod pressingplate set is rotatably arranged on the vertical plate, the two ends of the four-rod pressing plate set are connected with the left carrier roller and the right carrier roller correspondingly, the four-rod pressing plate set is a parallel hinge four-rod mechanism, the middle of the four-rod pressing plate set is rotatably connected with the vertical plate, and the axes of the left carrier roller and the right carrier roller can be always kept in a parallel state when the left carrier roller and the right carrier roller vertically swing; and a middle pressing roller is connected to the verticalplate in an up-and-down sliding mode, two middle rollers are arranged on the lower portion of the middle pressing roller, the middle rollers, the left carrier roller and the right carrier roller arelocated above and below two pipelines to be connected, the single pipeline is lifted and tends to be centered with the other pipeline in the opposite clamping process of the middle rollers and the carrier rollers, and then the whole device is rotated to ensure the centering property of the two to-be-connected pipelines.
