Abstract

The invention relates to a manual hydraulic power tool for screwing a pipe fitting, belonging to the technical field of pipelines. The tool is used for mounting the screwing pipe fitting, and comprises a screwing clamping head part and a hydraulic driving part that drives the screwing clamping head part. The slide rod on the screwing clamping head part is provided with a slide block and a fixed block, and a flat square groove matched with the U-shaped insertion piece is arranged on the slide rod. The screwing pipe fitting is mounted by driving the U-shaped insertion piece and the small insertion piece which has a special structure and is mounted on the U-shaped insertion piece, by the hydraulic driving part. The tool has large output strength and meets the requirement of mounting specified screwing pipe fitting. The structure of the tool is designed compactly and scientifically with long service life. The hydraulic power tool is light to operate and saves labor, thereby reducing the labor intensity of the operator greatly.

Description

technical field [0001] The invention relates to the field of pipelines, in particular to a manual hydraulic tool for installing sliding and tightening pipe fittings in pipeline connections. Background technique [0002] In the connection methods of plastic pipes or composite pipes and pipe fittings, there is a new type of sliding tight connection method, that is, the collar is inserted into the outer diameter of the pipe connection port, and at the same time, a pipe fitting body with pipe inner support and connection function is installed on the inner diameter of the pipe connection port. . Through the pipe fitting sliding tool, the collar is stressed and pushed to the flange part of the connecting end against the main body of the pipe fitting, so as to realize the fixed connection between the pipe fitting and the pipe material. At present, most of these tools are manually operated, such as the "collar compression pistol" of the authorized announcement number CN 2619760Y. T...
