Description

Pipe and flange perpendicularity correcting device

Technical Field

The utility model relates to the technical field of assembly of pipes and flanges, in particular to a pipe and flange perpendicularity correcting device.

Background

Flanges are parts for interconnecting pipes and are used for connecting pipe ends, and when the flanges are assembled on the pipes, in order to ensure the precision, quality and verticality of the connection between the pipes, the flange surface is required to be vertical to the axis of the pipe connection. In the current connection mode, the flange and the pipe end are firstly spot-welded at any position, then the measurement is carried out through a square, and the position is adjusted by continuously knocking the flange; or the adjustment is carried out by adding a wedge block, so as to achieve the aim of meeting the verticality. However, this method is not only inefficient, but also not highly accurate, has errors in adjusting the verticality, and is not able to ensure the coaxiality, which is time-consuming and labor-consuming. Based on this, the utility model provides a device for correcting the perpendicularity of a pipe and a flange.

the utility model relates to a pipe and flange perpendicularity correcting device which comprises a base, wherein a concave platform is arranged on the inner side of the base, and a through hole is formed in the center of the concave platform; a plurality of connecting rods are arranged on the periphery of the inner side of the base, and the other ends of the connecting rods are connected with clamping rings; the base, the connecting rod and the clamping ring form a tubular structure, the pipe is located in the tubular structure formed by the base, the connecting rod and the clamping ring, and the welding part of the flange extends to the inner side of the base through the through hole and is butted with the end part of the pipe.

Furthermore, the shape of the snap ring is a semicircular crescent.

Still further, the concrete quantity of a plurality of connecting rod is three, and the circumference distributes between base and snap ring.

Still further, a plurality of one end of connecting rod sets up on the base, the other end is worn out be provided with connecting bolt behind the snap ring.

Still further, the base is provided with the handle with the lateral wall of snap ring upper and lower parallel and level.

Compared with the prior art, the utility model has the beneficial technical effects that:

the utility model discloses a pipe and flange straightness correcting unit that hangs down is located the pipe in the tubular structure that base, connecting rod and snap ring formed, the weld part of flange is followed the base outside extends to through the through-hole the base is inboard, and with the butt joint of pipe tip is in the same place, realizes the location fast, has not only satisfied the straightness that hangs down of pipe and flange connection, has still guaranteed the axiality, has improved installation effectiveness and quality. In a word, the pipe and flange perpendicularity correcting device is simple in structure and convenient to operate, installation accuracy is guaranteed, and quality and efficiency are improved.
