Portable spigot and socket pipeline jointing machine

Abstract

The invention discloses a portable spigot and socket pipeline jointing machine which comprises a fixed pull rod seat, a pull rod, a sliding hole, a retractor device, a sliding pull rod seat, a water feeding spigot and socket pipe and a spigot and socket pipe thrust jointing machine seat. One end of the pull rod is fixedly connected with the fixed pull rod seat, and the other end of the pull rod is fixedly connected with the sliding pull rod seat. The sliding pull rod seat is connected inside a sliding groove formed in one end of the spigot and socket pipe thrust jointing machine seat in a sliding manner while one end of the sliding pull rod seat is fixedly connected with the output end of the retractor device. The retractor device is fixedly connected inside the spigot and socket pipe thrust jointing machine seat. The automatic jointing machine formed by the fixed pull rod seat, the pull rod, the retractor device and the spigot and socket pipe thrust jointing machine seat is simple in structure, portable and easy to operate, and saves time, labor, and human resource. Only two people can easily complete the onerous installation used to be finished by seven to eight persons. The installation speed is increased, working efficiency and installation quality are improved, and the occurrence of hidden dangers is prevented.

Description

technical field [0001] The invention relates to an interface machine, in particular to a portable socket pipe interface machine. Background technique [0002] The water supply cast iron socket pipe used in the fire protection system in the tunnel of the subway section is difficult, labor-intensive, low-efficiency, time-consuming, labor-intensive and labor-intensive during the connection process. Moreover, this kind of socket connection in the subway is limited by conditions. Only methods such as crowd tactics and chain hoists are used to connect pipes and pipes. For each pipe, it is 6000mm long, has an outer diameter of 170mm, and weighs 300 catties. For the water supply cast iron pipes, the sea of ​​people tactics is used, that is, at least 7 to 8 people lift up the ductile iron socket pipes at the same time for collision connection. This collision connection method has the same safety as the chain hoist. Hidden dangers, after a long time, the installation workers are prone ...

[0002] The water supply cast iron socket pipe used in the fire protection system in the subway tunnel is difficult, labor-intensive, low-efficiency, time-consuming, labor-intensive, and labor-intensive during the connection process.

Moreover, this kind of socket connection in the subway is limited by conditions. Only methods such as crowd tactics and chain hoists are used to connect pipes and pipes. For each pipe, it is 6000mm long, has an outer diameter of 170mm, and weighs 300 catties. For the water supply cast iron pipes, the sea of ​​people tactics is used, that is, at least 7 to 8 people lift up the ductile iron socket pipes at the same time for collision connection. This collision connection method has the same safety as the chain hoist. Hidden danger, after a long time, the installation workers are prone to fatigue and reduce the efficacy, and may also damage the anti-corrosion layer of the inner lining of the pipeline due to collision and cause the anti-corrosion lining at the mouth to fall off, etc.
