Embodiment Construction
[0048] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other implementations obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.
[0049] The invention provides a welding repair method for chains, which includes the following steps: firstly, sorting the chains, and selecting the chains whose wear conditions of the chain sleeves on the chains or / and wear conditions of the chain links on the chains affect the use of the chains ; Then, the chain link of the chain or / and the chain sleeve of the chain are repaired by overlay welding. The present invention does not need to replace the chain link...

The invention provides a welding repairing method for a chain, relates to the technical field of repairing of chains of heavy-duty dozers, and aims at solving the technical problem that a high-price chain joint or a high-price chain sleeve is to be replaced in case of serious abrasion of the chain, and the repairing cost of the chain is high. The method comprises the steps of sorting the chains, and selecting the chains which cannot be used normally due to the abrasion of the chain sleeves and / or the abrasion of the chain joints on the chains; and then processing the chain joints and / or thechain sleeves of the chains by welding deposit repairing. According to the method, the chain joints and the chain sleeves are not replaced, and the chain joints and the chain sleeves which are subjected to serious abrasion are welded and repaired until returning to the original states and recovering the use performances as well as meeting the use demands. The method is low in welding repairing cost, so that the chain repairing cost can be effectively decreased.
Description
technical field [0001] The invention relates to the technical field of heavy-duty bulldozer chain repair, in particular to a welding repair method for chains. Background technique [0002] A bulldozer is an earthwork machine capable of excavating, transporting, and discharging rock and soil, and has a wide range of uses. Bulldozers are roughly divided into crawler-type bulldozers and tire-type bulldozers. Crawler-type bulldozers have large traction and strong power. During the working process, the chain used in conjunction with the track shoes is easy to wear, and the existing chain repair method in the prior art is to replace the worn parts after the chain is disassembled as a whole. That is, at first the entire existing chain is disassembled, the severely worn chain sleeve is replaced, and the slightly worn chain sleeve is turned over. Then replace the severely worn chain links, and do not perform other treatments on the slightly worn chain links. Finally, replace any r...
