Abstract

The invention relates to the technical field of fully-mechanized excavating machine equipment, and discloses a hydraulic limiting device of a fully-mechanized excavating machine. The hydraulic limiting device comprises a fully-mechanized excavating machine body. A hydraulic pump station is mounted on a rear supporting frame of the fully-mechanized excavating machine body, a seven-linked valve setis mounted at the position of an operating handle of the fully-mechanized excavating machine body, the seven-linked valve set is connected with side limiting oil cylinders through a balance valve, andthe side limiting oil cylinders are fixed to the front and rear positions of a walking crawler frame of the fully-mechanized excavating machine body correspondingly. According to the hydraulic limiting device, limiting work of the fully-mechanized excavating machine can be achieved, and the accidents such as displacement and rolling-over of the fully-mechanized excavating machine when impact ground pressure appears can be completely eradicated. The hydraulic limiting device is easy to mount, easy and convenient to operate and capable of being applied and popularized in the same field. Full-automatic operation is achieved, the labor intensity of workers is reduced, the safety risk of the workers is reduced, and green mine construction rules are met.

Description

technical field [0001] The invention relates to the technical field of fully mechanized excavator equipment, in particular to a hydraulic limiter for fully mechanized excavators. Background technique [0002] Fully mechanized excavator, short for comprehensive mechanized roadheader, is a comprehensive mechanized equipment that integrates multiple functions of excavation, rock loading, coal transportation, even support, and nailing. Due to the restriction of pick steel, comprehensive mechanized excavation is only suitable for all-coal roadways. Generally, after comprehensive mechanized excavation is used, compared with the excavation process of drilling and blasting, the excavation progress can be increased by more than 30 times. [0003] Due to the lack of a limit device for the fully-mechanized excavator, the limit of the fully-mechanized excavator is realized by placing sleepers on both sides of the fuselage and setting small wooden stacks on the top. When using the meth...
