Rotary joint pipeline mounting structure and using method thereof

Abstract

The invention discloses a rotary joint pipeline mounting structure and a using method thereof, and belongs to the technical field of hydraulic clay guns. The problems that errors exist between the rotation center of a rotary joint and the rotation center of a cantilever, the situation of force holding exists in the pipeline fixing process, and the rotary joint is prone to being damaged in the rotating process, so that oil leakage is caused are solved. The rotary joint pipeline mounting structure comprises a cantilever, a rotary joint shell, a rotary joint mandrel and an oil cylinder oil supply pipeline system; the rotary joint mandrel is arranged in the rotary joint shell, one end of the oil cylinder oil supply pipeline system is connected with the rotary joint mandrel, and the other end of the oil cylinder oil supply pipeline system is fixed on the cantilever; the oil cylinder oil supply pipeline system comprises a hose set, and the hose set is arranged at the position far away from an end of the oil cylinder oil supply pipeline system; and a shifting roller is further connected to the rotary joint mandrel, the shifting roller is connected with a shifting fork, the bottom of the shifting fork is connected with a support, and the support is fixedly connected to the cantilever. According to the rotary joint pipeline mounting structure and the using method thereof, the situations of mutual force holding, moving and the like of the rotary joint shell and the rotary joint mandrel are avoided, and the rotary joint is not prone to being damaged.

Description

technical field [0001] The application relates to the technical field of hydraulic mud guns, and in particular, to a rotary joint pipeline installation structure and a method of using the same. Background technique [0002] The production of ironworks in iron and steel enterprises is mainly blast furnace production, and mud gun is a key equipment for blast furnace production. The mud gun is a necessary equipment in front of the furnace in the smelting industry. Its function is to quickly and accurately block the tap hole after the iron is discharged, so that the blast furnace can quickly enter the next cycle of operation. When the hydraulic mud gun rotates, the cantilever rotates relative to the fixed base around the center of rotation. The hydraulic hard pipe on the cantilever and the hard pipe on the fixed base are connected by a rotary joint to realize the rotation of the pipeline, and the rotary joint is fixedly installed at the center of rotation. [0003] In the prior...

AI Technical Summary

Problems solved by technology

[0004] The embodiment of the present application provides a rotary joint pipeline installation structure and its use method, which solves the problem of errors in the processing and installation of the rotary joint in the prior art, which may cause the rotation of the rotary joint to be out of center with the rotation of the cantilever, resulting in misalignment when the cantilever rotates. The hard pipe fixed on the top will pull the rotary joint mandrel, causing the rotary joint mandrel and the rotary joint shell to hold together, grind each other and damage the seal, resulting in oil leakage. This application can use the hose group of the oil supply pipeline system of the oil cylinder Compensation, the rotary joint shell and the rotary joint mandrel will not have mutual holding force, serial movement, etc. The rotary joint mandrel does not drive its rotation through the flange of the oil outlet and the oil supply pipeline system of the oil cylinder, but independently The mandrel of the rotary joint is driven to rotate by the fork and the stick, so as to avoid the oil leakage caused by the stress on the oil outlet flange
