Problems solved by technology

[0002] The guide device of the existing reciprocating impact mining machine has a lot of direct wear on the parts during operation. The existence of a lot of wear not only causes damage to the contact surface, but also produces many scratches or grooves, and high temperature sintering is easy to occur between the contact surfaces , and even the phenomenon of gluing or seizure of the contact surface will affect the quality and performance of the product, cause damage to the equipment components, cause the equipment function to fail to be realized, and easily cause production safety accidents
[0003] Aiming at the existing common and simple anti-wear methods such as oil injection, which are far from meeting the needs of fast movement between parts, in order to solve the problem of wear between equipment parts, the present invention proposes a wear-resistant device for excavators

Abstract

The invention relates to an excavator suspension wear resistance method and an excavator wear resistance device for implementing the method. The device comprises a drive mechanism, a friction mechanism, excavating mechanisms and the like. The friction mechanism includes an impact guide member and a guide support member, etc. The drive mechanism includes a power impact member and a power support member, etc. The impact guide member is disposed at the guide support member. Two ends of the impact guide member are in split connection with the excavating mechanisms. The power support member supports the power impact member in impacting. The power impact member drives the impact guide member to make reciprocating motion. The impact guide member rights the reciprocating impact directions of the excavating mechanisms. The impact guide member and / or the guide support member include(s) a suspension mechanism or a wear resistance mechanism. The device has the advantages of reliable working, stable performance, low cost and easy popularization.

Description

technical field [0001] The invention belongs to the field of mining, and in particular relates to a method for suspending wear resistance of a mining machine and a wear resistance device of the mining machine implementing the method. Background technique [0002] The guide device of the existing reciprocating impact mining machine has a lot of direct wear on the parts during operation. The existence of a lot of wear not only causes damage to the contact surface, but also produces many scratches or grooves, and high temperature sintering is easy to occur between the contact surfaces , and even the phenomenon of gluing or seizure of the contact surface will affect the quality and performance of the product, cause damage to the equipment components, cause the equipment function to fail to be realized, and easily cause production safety accidents. [0003] In view of the fact that the existing common anti-wear methods such as oil injection are far from meeting the needs of fast ...
