Embodiment Construction

[0029] In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0030] see Figure 1 to Figure 10 , the present invention designs a kind of insulation pipe outer casing port gauge circle and holding mechanism to assist the pipe threading operation in the production process of the "pipe-in-pipe" type prefabricated direct-buried insulation pipe. In order to achieve the above object, the present invention adopts the following technical solutions:

[0031] The port gauge circle and holding mechanism of the outer casing of the insulation tube are composed of a port gauge circle mechanism and a roundness retaining ring (2).

[0032] The port gauge circle mechanism is composed of a base ring (3), a cone panel (4) and a small ring (5). The base ring (3) has eight engaging grooves (A) evenly distributed in the c...

Abstract

The invention relates to an insulation pipe outer sleeve pipe end opening circle gauging and maintaining mechanism and a pipe penetrating method thereof. The overall structure comprises an end openingcircle gauging mechanism and a roundness maintaining ring. Circle gauging and roundness maintaining of an insulation pipe outer sleeve pipe end opening are completed once. The insulation pipe outer sleeve pipe end opening circle gauging and maintaining mechanism and the pipe penetrating method thereof can be used for pipe penetrating operation during production of pipe-in-pipe type prefabricateddirect-buried insulating pipes so as to save labor and improve work efficiency.

Description

technical field [0001] The invention relates to a gauge circle, a holding mechanism and a pipe threading method for an outer casing port of a thermal insulation pipe, and belongs to the field of mechanical design. Background technique [0002] The "pipe-in-pipe" prefabricated direct-buried thermal insulation pipe is one of the main pipeline forms used in urban heating projects at present. Its basic structure includes working steel pipes, thermal insulation layers, outer casings, and leakage alarm lines. The pipe threading operation is an indispensable link in the production process of the "pipe-in-pipe" type prefabricated direct-buried thermal insulation pipe. Inside. In the pipe threading operation, the deformation of the outer casing port brings great trouble to the operation, and usually requires 3-5 people to cooperate to complete the operation, and the operation efficiency is extremely low. Based on the actual needs of the pipe threading operation, the present inventi...
