Municipal pipeline rubber ring sleeving device

Abstract

The invention relates to a municipal pipeline rubber ring sleeving device, and effectively solves the problems that in the existing large-diameter cement pipe rubber ring mounting process, operation is complex and breakpoints and leakage points are likely to be caused in the mounting process. According to the technical scheme, the device comprises a vertical pipe, a vertical rod with the upper end extending out of the vertical pipe is coaxially inserted into the upper end of the vertical pipe, a compressed spring enabling the vertical rod to reset and extend upwards is further arranged in the vertical pipe, a supporting rod with the axis in the horizontal front-back direction is arranged at the upper end of the vertical rod, a limiting protrusion is arranged in the position, close to the back end, of the supporting rod, a positioning rod is detachably installed at the lower end of the vertical pipe, two connecting rods arranged in a bilateral symmetry mode are hinged to the front end of the vertical pipe, an arc-shaped plate coaxial with the cement pipeline is arranged at the free ends of the connecting rods, a limiting block is arranged in the position, close to the back end, of the arc-shaped plate, a limiting groove with a transverse opening in the front-back direction is formed in the front end of the vertical pipe, and each connecting rod is provided with a limiting pin arranged in the corresponding limiting groove.

Description

technical field [0001] The invention relates to the field of rubber ring installation tools, in particular to a rubber ring set device for municipal pipelines. Background technique [0002] Cement pipes are often used for municipal drainage. The diameter of cement pipes is generally very large, and some even exceed two meters. When two cement pipes are connected, a rubber ring needs to be put on the socket. The function of the rubber ring is to make the two cement pipes The pipe can have a good sealing effect after installation. At present, the sealing ring set is basically installed manually. When the rubber ring shrinks, the diameter is slightly smaller than the outer diameter of the socket. Therefore, it is necessary to put the rubber ring The rubber ring can only be put on by stretching it out and using two people to apply reverse force at the same time. This rubber ring set method requires at least two labors and requires the tacit cooperation between the workers. The i...
