Abstract

The invention discloses a positioning device and method used for guaranteeing two ends of a core-penetrating bolt to be equal in extending length and mainly aims to solve the problem that the two ends of the core-penetrating bolt are different in extending length due to the fact that the core-penetrating bolt is mounted manually in the prior art. The positioning device comprises a base, a guide rail and a positioning ferrule, the guide rail is vertically arranged on the base and provided with a groove penetrating the base and a scale, a zero graduation line of the scale is flush with the undersurface of the base, the positioning ferrule is disposed on the guide rail in a sleeved manner, a convex block matched with the groove is arranged on the inner side of the positioning ferrule, and a fastening screw used for locking and fixing the positioning ferrule on the guide rail is arranged on the positioning ferrule. By the positioning device and method, extending length of the two ends of the core-penetrating bolt can be controlled accurately in the process of mounting.

Description

technical field [0001] The invention relates to the technical field of engineering equipment installation, in particular to a positioning device and method for ensuring that the protruding lengths of both ends of a core-through bolt are equal. Background technique [0002] In the process of engineering equipment installation, pipeline installation is very common. As a common pipeline connection method, flange connection means that flanges are cast at both ends of the pipeline, and there is a seal on the end face of the flange. The groove is equipped with a sealing ring, and the pipes are tightly connected together with bolts or core bolts after butt joint. The flange connection method is widely used in pipeline connections in many fields such as electric power, petroleum and chemical industry. Usually, there will be liquid in the connected pipeline, which is oil or other dangerous chemical raw materials, such as large transformers. The cooling oil circuit contains cooling o...
