Problems solved by technology

Under the existing technical conditions, the hot-melt sleeve is generally placed on the outer wall of the pipeline manually, and the ratchet mechanism is used to fit and fasten the hot-melt sleeve and the outer protective tube of the pipeline, and then the electric heating operation is performed. This working method is due to the If the fastening force is not enough, the binding tape is prone to loosening, it is difficult to ensure the fit between the hot-melt sleeve and the outer protective tube, and to maintain a stable given pressure during hot-melt bonding, which will cause fusion at the hot-melt point If the quality is not guaranteed, there will be construction defects such as leakage and cracking at the pipeline interface, which will cause the polyurethane insulation layer in the prefabricated direct-buried insulation pipe to carbonize and fail, affecting the service life of the entire pipeline, and causing quality accidents in insulation construction

Abstract

The invention provides a portable rapid fastening device. The device comprises a shell and a rocker arm; two guide rollers are arranged at one end of the shell, and the two guide rollers are symmetrically arranged in an up-and-down mode; a winding roller and a detachable fast pin are arranged at the other end of the shell, and the winding roller and the fast pin are symmetrically arranged in an up-and-down mode; and through holes matched with the binding belt is formed in the winding roller, the rocker arm is arranged on the shell, and the rocker arm is rotationally connected with the winding roller. According to the portable rapid fastening device, the shell, the guide roller, the winding roller and the rocker arm can be matched in use so that the rapid and stable fastening pressure can be realized, the fit degree between the hot-melting sleeve and the pipeline is guaranteed, the operation is convenient, the using effect is good, and the application range is wide.

Description

technical field [0001] The invention belongs to the technical field of prefabricated direct-buried thermal insulation pipe sheath construction technology, and in particular relates to a portable fast fastening device. Background technique [0002] In the laying of heating pipelines, it is necessary to insulate the exposed steel pipes connected to the heating pipelines. The outer sheath of the interface is generally formed by heat-melting the hot-melt sleeve and the outer sheath of the pipeline, so it is necessary to closely fit the hot-melt sleeve and the outer sheath of the pipeline. Under the existing technical conditions, the hot-melt sleeve is generally placed on the outer wall of the pipeline manually, and the ratchet mechanism is used to fit and fasten the hot-melt sleeve and the outer protective tube of the pipeline, and then the electric heating operation is performed. This working method is due to the If the fastening force is not enough, the binding tape is prone ...
