Abstract
The utility model relates to the field of hydraulic tools, in particular to a hydraulic tool for installing pipelines, which is provided with a manual pump, an oil pressure gage and a change-over valve, and is characterized in that two high pressure oil pipes on the manual pump are respectively connected with a front cavity and a rear cavity of two oil cylinders, two ends of a front clamping plate in a U shape are respectively and fixedly connected on cylinder bodies of the two oil cylinders through bolts, two ends of a rear clamping plate in a U shape are respectively connected with cylinder rods of the two oil cylinders through nuts, and two corresponding end surfaces of the front clamping plate and the rear clamping plate are parallel. The hydraulic tool has reasonable design, simple structure and convenient use and operation, not only can guarantee the connection intensity of the pipelines, but also can avoid damaging the pipe body, and can improve the working efficiency simultaneously.
Description
Technical field
The utility model relates to the hydraulic tool field, specifically a kind of hydraulic tool that is used for the pipeline installation.
Background technology
Pipe joint at present is being connected and installed of screw thread, generally uses instruments such as pipe wrench, chain wrench, band pincers, hook spanner, in the process of installing; the phenomenon that instrument skids occurs through regular meeting on pipeline, easily on body, cause cut, destroy body; in addition, also be difficult for guaranteeing the bonding strength of pipeline.
The utility model content
The purpose of this utility model is in order to solve the deficiency of above-mentioned technology, to provide a kind of rational in infrastructure, simple, easily making, and is easy to use, can improve the hydraulic tool that pipeline is installed that is used for of pipeline bonding strength.
The utility model solves the scheme that its technical problem takes: be used for the hydraulic tool that pipeline is installed, be provided with manual pump, oil pressure gauge, reversal valve, it is characterized in that two high-pressure oil pipes on the manual pump are connected with the front/back cavity of two oil cylinders respectively, be that the two ends of clamp are fixedly connected on respectively on the cylinder body of two oil cylinders by bolt before the U type, be that the two ends of clamp are connected with the cylinder bar of two oil cylinders respectively by nut behind the U type, two corresponding end faces of preceding clamp and back clamp parallel.
The utility model is reasonable in design, and is simple in structure, uses, easy to operate, can guarantee the bonding strength of pipeline, avoids damaging body again, also improved operating efficiency simultaneously.
