Problems solved by technology

[0003] Since the top beam and the cover beam are always in the environment of high working resistance during the process of supporting the stope roof, they are subjected to a large bending moment, which in turn causes the overall stress concentration of the balance lugs, and the balance lugs are prone to occur. break

Abstract

The invention discloses a balance lug seat, a top beam, a shield beam and a hydraulic support. The balance lug seat comprises a lug plate and a reinforcing fixing assembly, wherein the lug plate is welded to a top plate; and the reinforcing fixing assembly is connected with the lug plate and the top plate and used for reinforcing and fixing the lug plate to the top plate. According to the balance lug seat, the lug plate is directly welded to the top plate of the top beam or the top plate of the shield beam, and the problem that in the related technology, the lug plate is prone to cracking after being stressed due to the fact that the number of welding seams between a clamping plate and the lug plate is large during welding of the clamping plate and the lug plate can be avoided.

Description

technical field [0001] The invention belongs to the technical field of hydraulic supports, and in particular relates to a balance ear seat, a top beam, a cover beam and a hydraulic support. Background technique [0002] The hydraulic support is the equipment that plays a supporting role among the three fully mechanized mining machines. Its main function is to support the roof of the stope and provide a safe working and maintenance space for the shearer and the scraper conveyor. With the continuous development of coal mining, the requirements for hydraulic supports are getting higher and higher. Among them, both the top beam and the cover beam are important components of the hydraulic support. At present, while the top beam and the cover beam of the existing hydraulic support are hinged, the first end of the hydraulic cylinder is connected to the balance ear seat on the top beam. The hinge, and the second end of the hydraulic oil cylinder are hinged with the balance ear seat...
