Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with specific embodiments

[0021] Such as figure 1 As shown, the fully mechanized mining hydraulic support remanufacturing process includes the following steps:

[0022] 1. Cleaning before dismantling: recycle waste parts, use high-pressure washing machines and semi-closed circulating pools to clean parts, remove coal powder, coal gangue and other sundries on the surface of the bracket, and focus on cleaning the column socket and the front and rear , Coal powder in the upper connecting rod.

[0023] 2. Dismantling: Use a press to disassemble the disassembled waste parts without damage.

[0024] 1) Remove the connecting rod pin and the upper pin of the column, and unfold the bracket;

[0025] 2) Remove the upper connecting rod, front and rear connecting rods, front telescopic beam, rear plate, front telescopic jack, rear tail beam jack, rear plate jack, and push jack. Place it on a wooden pad to ...

Abstract

The invention relates to a remanufacturing process of a fully-mechanized coal mining hydraulic bracket. The remanufacturing process comprises the following steps of: washing before dismounting, dismounting, washing after dismounting, detecting, remanufacturing, assembling, testing a whole machine, spraying paint and storing. Aiming at damaged parts, a laser cladding restoration technology is adopted to remanufacture all parts of the fully-mechanized coal mining hydraulic bracket on the basis of performance failure analysis and service life evaluation analysis, so that the defects of limited machining times, bad roughness and bad effects of a previous restoration process are overcome, the remanufacturing efficiency is improved, the strength of a remanufactured structural piece is enhanced, the service lives of the structural piece and a machined piece are prolonged, the quality of a product is ensured, the production cost is reduced and environmental friendliness can be achieved.

Description

technical field [0001] The invention relates to a fully mechanized mining hydraulic support remanufacturing process, which belongs to the technical field of mining machinery. Background technique [0002] The sustained and rapid development of China's economy and the trend of heavy industrialization have put China's relatively scarce natural resources under enormous pressure. In this context, the pursuit of building a "4R" circular economy development model of Reduce, Reuse, Recycle and Remanufacture will change the long-standing pursuit of scale and speed. The concept of development is not only a policy orientation, but also recognized by more and more people in the industry. Fully mechanized mining hydraulic supports are an important part of the mining equipment manufacturing industry, and the available surplus of the mining machinery industry is relatively high. Therefore, the development of the remanufacturing industry has gradually become a new way for mining engin...
