Problems solved by technology

[0002] The roadheader is a machine used to dig a straight underground roadway. There is a shovel on the roadheader. The body of the roadheader and the shovel are connected by two connecting ears. During the underground operation of the roadheader, the body of the roadheader and the shovel Due to the tension and fatigue stress of the shoveling plate, the connecting ear is subjected to excessive force during the lifting of the well, causing serious deformation and distortion, and also fractures. The strength and rigidity are seriously insufficient, and the damage is frequent, resulting in a decrease in production efficiency and an increase in labor intensity. Large, the equipment cannot be wasted after the breakage, and an effective way can be selected for repair

Embodiment Construction

[0016] Such as Figure 1~Figure 2 As shown, a repair method for connecting ears, including two connecting ears 1, sticking plate 2, reinforcement plate 3, rib plate 4, process shaft 5 and distance pad 6, each connecting ear includes two ear plates, the method Include the following steps:

[0017] (1) Process and flatten the fracture surface of the two broken ear plates of each connecting ear 1, process welding grooves, and process the welding positions on the veneer 2, reinforcement plate 3 and rib plate 4 into grooves;

[0018] (2) Use the broken two ear plates of each connecting ear that has been grooved in step (1) as a template, and mark the welding position of the broken part of the connecting ear on the main body, which is convenient for welding the plate, reinforcement plate and Rib position;

[0019] (3) Insert the two connecting lugs with the grooves processed in step (1) onto the two ends of the process shaft 5 respectively, and each connecting lug 1 breaks and ins...

Abstract

The invention discloses a repair method of a connecting lug. The connecting lug, a flitch, a reinforcing plate, a rib plate, a process shaft and a distance pad are involved; the repair of the connecting lug is realized by virtue of the repair process of chamfering, weld line working, flitch welding, process shaft and distance pad penetrating, and then rib plate and reinforcing plate welding. According to the repair method of the connecting lug, the broken connecting lug is welded and reinforced by use of the flitch, the reinforcing plate and the rib plate of simple structures, and an airtight reinforcing cavity structure is formed, and therefore, the problems of serious deformation and breakage in the prior art are effectively solved and the connecting lug is enabled to be high in strength, good in stiffness, convenient to manufacture and maintain, less in maintenance and high in production efficiency and have the characteristic of simple structure; the process shaft and the distance pad are adopted to effectively guarantee the accuracy of repair and ensure the accuracy of the mounting position; the repair method is simple.

Description

technical field [0001] The invention belongs to the field of coal machinery, in particular to a method for repairing high-strength connecting ears. Background technique [0002] The roadheader is a machine used to dig a straight underground roadway. There is a shovel on the roadheader. The body of the roadheader and the shovel are connected by two connecting ears. During the underground operation of the roadheader, the body of the roadheader and the shovel Due to the tension and fatigue stress of the shoveling plate, the connecting ear is subjected to excessive force during the lifting of the well, causing serious deformation and distortion, and also fractures. The strength and rigidity are seriously insufficient, and the damage is frequent, resulting in a decrease in production efficiency and an increase in labor intensity. Large, the equipment cannot be wasted after the breakage, and an effective way can be selected for repair. Contents of the invention [0003] The tec...
