液压支架
By optimizing the structure of the hydraulic support's column and linkage assembly, the vertical movement of the top beam during lifting and lowering is ensured, solving the stability problem caused by the unreasonable arrangement of the four linkages in traditional hydraulic supports, and achieving higher working stability and linear motion effect.

Abstract
本发明涉及一种液压支架，所述液压支架包括底座、顶梁、立柱组件和连杆组件，连杆组件包括第一杆、第二杆、第三杆、第四杆和连接杆，第一杆上端和第二杆上端均与顶梁可枢转地连接，第一杆上端和第二杆上端均位于第一枢转点，第三杆下端和第四杆下端沿第一方向间隔布置且均与底座可枢转地连接，第一杆下端与第三杆上端可枢转地连接，第二杆下端与第四杆上端可枢转地连接，连接杆一端与第三杆可枢转地连接且具有第二枢转点，连接杆另一端与第四杆可枢转地连接且具有第三枢转点，第一枢转点和第二枢转点的连线均始终正交于第二枢转点和第三枢转点的连线。本发明的液压支架升降运动时的水平摆幅较小，有利于提高液压支架工作时的稳定性。
