Abstract

The invention provides a side pushing device and a hydraulic support. The side pushing device comprises a first side pushing driving assembly, a second side pushing driving assembly and side protection plates; the first side pushing driving assembly is provided with a first driving end and a first fixing end, and the first fixing end is connected with a supporting plate outside the side pushing device; the second side pushing driving assembly is provided with a second driving end and a second fixing end, the second fixing end is connected with the supporting plate, and the second side pushingdriving assembly and the first side pushing driving assembly are oppositely arranged in the first direction; the side protection plates are arranged at the first driving end and the second driving endcorrespondingly; and the first driving end can move in the first direction relative to the first fixing end, and the second driving end can move in the first direction relative to the second fixing end. According to the technical scheme, the first side pushing driving assembly and the second side pushing driving assembly are relatively independent and drive the corresponding side protection plates independently, so that the use stability and reliability of the side pushing device are ensured, and the stable and reliable work of the side pushing device is further ensured.

Description

technical field [0001] The invention relates to the technical field of hydraulic support equipment, in particular to a lateral thrust device and a hydraulic support. Background technique [0002] At present, the hydraulic support is the supporting equipment of fully mechanized mining face. During the coal mining process, it is mainly used to support and control the roof of the working face, isolate the goaf, and provide a safe and reliable working space for coal mining equipment. Due to the long coal mining face, many supports are required to work side by side. In order to prevent coal leakage from entering the working space between adjacent supports, hydraulic supports are usually equipped with side thrusters on the top beam and cover beam to fill the space between adjacent supports. Clearance. [0003] The side thruster in the related art is usually provided with a single side thruster driving assembly, and the retraction movement of the two side guards is driven by one s...
