Abstract

The invention discloses a stable type left-and-right type end socket support. The stable type left-and-right type end socket support comprises a left support body and a right support body which are symmetrically arranged in structure. The left support body and the right support body each comprise a front top beam, a back top beam, a front base and a back base, wherein each front top beam is hinged to the corresponding back top beam, and each front base is hinged to the corresponding back base. A shielding beam is arranged at the back end of each back top beam, the lower end of each shielding beam is connected with the back end of the corresponding back base through a front connecting rod and a back connecting rod, two stand columns are arranged between the back portion of each back base and the corresponding back top beam, a stand column is arranged between the front portion of each back base and the corresponding back top beam, a stand column is arranged between the front portion of each front base and the corresponding front top beam, and a support adjustment jack is arranged between the front top beam of the left support body and the front top beam of the right support body. The overall stability of the back portion of the support and the end socket support is greatly improved, and meanwhile the supporting capacity of the back portion of the support is improved.

Description

technical field [0001] The invention relates to a hydraulic support for coal mines, in particular to a stable left and right end support. Background technique [0002] At present, many fully-mechanized working faces are equipped with end brackets in the lower trough to speed up the advancing speed of the transport equipment in the trough, thereby ensuring the rapid advancement of the working face as a whole. Such terminal supports can be generally divided into two types: front and rear terminal supports and left and right terminal supports. Among them, the left and right end brackets are affected by the narrow and long structure of the brackets, and their stability is poor, and they often tilt or even topple over, which greatly reduces the use efficiency of this type of frame. Contents of the invention [0003] The purpose of the present invention is to provide a stable left and right type end bracket with good stability and strong supporting capacity. [0004] The purpo...
