Pipeline butt joint connecting device for construction site

Abstract

The invention discloses a pipeline butt joint connecting device for a construction site. The pipeline butt joint connecting device comprises a first fixing frame, sliding grooves are formed in the twosides of one end of the first fixing frame, and a flush mechanism is arranged in the middles of the inner walls of the two sliding grooves; the flush mechanism comprises main moving T-shaped rods, amain moving circular ring, a main fixing circular ring, a main double-head screw rod, a sawtooth rotating wheel, an inner sawtooth belt, a slave double-head screw rod, a slave moving T-shaped rod, a second fixing frame, a slave moving circular ring and a slave fixing circular ring; and the main moving T-shaped rods are arranged in the middles of the inner walls of the two sliding grooves. According to the pipeline butt joint connecting device, through arrangement of the main moving T-shaped rods, the main moving circular ring, the main fixing circular ring, the main double-head screw rod, thesawtooth rotating wheel, the inner sawtooth belt, the slave double-head screw rod, the slave moving T-shaped rod, the second fixing frame, the slave moving circular ring and the slave fixing circularring, the internal center points of two connecting pipes can be kept perpendicular, then extrusion installation between the two connecting pipes and a three-way connecting joint is facilitated, and the installation difficulty between the connecting pipes and the three-way connecting joint is reduced.

Description

technical field [0001] The invention relates to the technical field of pipeline connection, in particular to a pipeline butt joint connection device used on a construction site. Background technique [0002] In the pipeline laying process, due to the limited length of the pipeline, the pipeline generally needs to be connected. Among them, there are many ways to connect the pipeline, and the most commonly used method is welding. The connection method has the advantages of direct operation, simple structure and beautiful appearance; [0003] However, the existing pipeline connection device does not have a device for positioning the center of the pipeline before splicing, which leads to deviations in the pipeline connection process, so that the pipeline needs to be rotated before it can be used normally. This method is difficult to operate and easy to operate. Causes damage to pipe connections. Contents of the invention [0004] The present invention provides a pipeline butt...

Problems solved by technology

[0004] The present invention provides a pipeline butt joint connection device for construction sites, which can effectively solve the problems in the above-mentioned background technology. However, the existing pipeline connection device does not have a device for positioning the center of the pipeline before splicing, which leads to a problem in the pipeline connection process. There is a deviation in the pipe, so the pipe needs to be rotated to be able to use it normally. This method is difficult to operate, and it is easy to cause damage to the pipe connection.
