Abstract

The invention discloses a prefabricated directly-buried thermal insulation pipe connecting device which comprises a rack, and a first sliding rail is arranged on the rack; the telescopic part is installed on the rack, and the output end of the telescopic part is connected with a sliding block sliding on the first sliding rail; at least one first thermal insulation pipe fixing sleeve and a second thermal insulation pipe fixing sleeve are connected to the fixed section, located on the telescopic part, of the rack, and the second thermal insulation pipe fixing sleeve is located on the telescopic section of the telescopic part and fixed to the sliding block; the connecting device further comprises an end face cutting mechanism which is installed on the machine frame and can be arranged between the two heat preservation pipes to cut the end faces of the two heat preservation pipes. The end face thermoplastic mechanism is mounted on the rack and can be arranged between the two thermal insulation pipes to heat and soften the end faces of the thermal insulation pipes; after machining is completed, only the telescopic part needs to be shrunk, so that the two ends of the two thermal insulation pipes are attached under driving of the sliding blocks, the end faces of the thermal insulation pipes are conveniently machined, and the beneficial effects of being accurate in positioning, smooth in joint and the like are achieved.

Description

technical field [0001] The invention relates to the technical field of thermal insulation pipes, in particular to a connection device for prefabricated directly buried thermal insulation pipes. Background technique [0002] Prefabricated directly 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 getting larger and larger, and its scope of use is also getting wider and wider. The prefabricated direct buried thermal insulation pipeline has many advantages such as waterproof, good anti-corrosion performance, saving investment, shortening the construction period and low maintenance cost. The prefabricated direct buried pipe currently used is composed of steel pipe, bracket, thermal insulation layer and protective layer. According to the design and customer requirements, seamless pipe spiral welding and straight seam pipe are generally selected. After the surfa...
