Description

Pipeline butt joint mechanism Technical Field The utility model relates to the technical field of pipeline butt joint, in particular to a pipeline butt joint mechanism. Background In industrial piping systems, flange connections are a widely used means of pipe interfacing. The two flange faces are placed face to face and are fastened through bolts to realize sealing connection, so that safe and stable operation of a pipeline system is ensured. However, in the actual installation process, the existing flange connection method has some inconveniences, especially, extra operation steps are needed in the bolt tightening process, and the construction difficulty and the time cost are increased. Conventional flanged connections typically require two-handed cooperation when tightening bolts, one hand securing the bolts against rotation using a wrench and the other hand tightening with a torque wrench. Therefore, it is necessary to provide a pipe docking mechanism to solve the above problems. Disclosure of utility model The utility model aims to solve the problem that the traditional flange connection usually needs two hands to cooperate when the bolt is screwed, wherein one hand uses a spanner to fix the bolt to prevent the bolt from rotating, and the other hand uses a torque spanner to screw. The utility model adopts the following technical scheme for realizing the purposes: The utility model provides a pipeline docking mechanism, includes the pipeline that is provided with the flange, a plurality of bolt holes have been seted up on the flange, the opening with the bolt hole intercommunication has been seted up to the flange edge, peg graft in the bolt hole has the bolt spare, the lateral surface fixedly connected with of bolt spare can peg graft the location strip in the opening, the other pot head of bolt spare is equipped with the baffle, and threaded connection has the nut on the bolt spare of this end, be used for with the tight laminating flange in baffle top. Further, the upper end of the baffle is fixedly connected with a pressing plate attached to the outer side face of the flange, and the lower end face of the pressing plate is fixedly connected with a plugboard which can be inserted into the notch. Further, the hexagonal end upper end fixedly connected with square piece of bolt spare, the clamp plate is towards the one end fixedly connected with inserted bar of the hexagonal end of bolt spare, the inserted bar can peg graft in the jack of seting up in the square piece. Further, a through hole for the bolt to pass through is formed in the middle of the baffle. Further, the lower end of the baffle is attached to the outer side face of the pipeline. Compared with the prior art, the utility model has the beneficial effects that: 1. According to the utility model, through the matching arrangement among the notch, the bolt piece, the baffle plate and the nut, the rotation can be prevented when the bolt piece is installed, and the bolt piece is only required to be propped by fingers and is not moved out of the bolt hole, so that the butt joint of pipelines is facilitated. 2. According to the utility model, through the cooperation arrangement among the pressing plate, the plugboard, the inserted link, the square block and the jack, the strength of the notch can be enhanced, and the flange at the notch is prevented from being deformed under force.
