Abstract

The invention belongs to the field of heat insulation pipe manufacturing machines, and particularly relates to a hydraulic air sealing machine for an outer sleeve. The hydraulic air sealing machine comprises a moving frame, a hydraulic cylinder, a pressing plate and a locking plate. The hydraulic cylinder is fixed to the upper portion of the moving frame, a piston rod of the hydraulic cylinder is connected with the locking plate, U-shaped grooves are formed in the two sides of the locking plate, the lower portion of the locking plate is fixedly connected with the pressing plate, a working table matched with the pressing plate is arranged on the lower portion of the pressing plate and fixed to the outer side of the moving frame, and moving wheels are arranged at the bottom of the moving frame. The hydraulic air sealing machine is simple in structure; the hydraulic cylinder arranged on the moving frame can drive the pressing plate to move downwards to be matched with the working table; the hydraulic air sealing machine can effectively prevent air leakage in the blocking process.

Description

technical field [0001] The invention belongs to the field of insulation pipe manufacturing machinery, and in particular relates to a hydraulic air sealing machine for an outer casing. Background technique [0002] Prefabricated direct-buried thermal insulation pipes are mainly used for district heating external network pipelines. With the promotion of central heating in the country, its consumption is increasing and its application range is becoming wider and wider. Prefabricated directly buried thermal insulation pipeline has many advantages such as waterproof, good anti-corrosion performance, saving investment, shortening construction period, and low maintenance cost. [0003] The prefabricated direct-buried pipes currently used are composed of steel pipes, brackets, insulation layers, and outer casings. According to the design and customer requirements, spiral welded seamless pipes and straight seam pipes are generally used. The polyethylene outer sleeve is made of high-...
