Chain wrench for engine oil filter of mining truck and use method

Abstract

The invention relates to a chain wrench for an engine oil filter of a mining truck and a use method, and belongs to the field of machines. The chain wrench for the engine oil filter of the mining truck comprises a first steel tube, a second steel tube, a universal joint and a universal joint fixing sleeve, wherein one end of the second steel tube is fixedly connected to the middle of the first steel tube to form a T-shaped structure; the other end of the second steel tube is fixedly connected with a fixed end of a universal joint; and a universal joint fixing sleeve is in sleeve joint with thesecond steel tube and the universal joint, and can move up and down. Through the adoption of the universal joint and the fixing sleeve, the design defects of an original tool are changed. A three-stage handcuff-type chain wrench structure is adopted, so that maintenance personnel can apply force uniformly; the probability of damage to the engine oil filter of the mining truck by screwing is lowered; the oil leakage failure is prevented; and the maintenance cost is lowered. Secondly, the universal joint and a universal joint casing structure are adopted, so that the maintenance personnel can flexibly change the standing position, the force applying direction and the force applying posture; the space and time of safe observation are increased; and the potential safety hazard for personnel who repairs machines of the type is lowered.

Description

technical field [0001] The invention relates to a tool used for an engine / diesel oil filter of a mine truck, in particular to a chain puller used for an engine oil filter element of a mine truck and a using method thereof. belongs to the field of machinery. Background technique [0002] Currently commercially available mining trucks (830e, 730e630e, sf33900) have special tools for engine / diesel filter, only T-bar combination chain wrench, the force is very uneven when used, and it is easy to break the engine / diesel filter element during maintenance , causing oil seepage / leakage, which in turn causes engine failure. It is worth noting that it cannot change the direction of force and the staff can only stand directly under the filter element. There are risks such as not having enough time to react and not having enough space to escape when a sudden car slip occurs. Contents of the invention [0003] The object of the present invention is to provide a chain puller for the o...
