Embodiment Construction

[0020] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0021] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown in the figure, a self-locking movable side guard fixing device with one-way operation includes a guide rod (5-1), a cylindrical coil spring (5-2), and an elastic steel rod that can be fixed by self-locking ( 5-3), sleeve (5-4), sealing plate (5-5), fixed seat (5-6), stop bolt (5-7), slideway guide rod fixing pin (5-8) , fixed pin shaft (5-9), slideway guide rod (5-1), cylindrical coil spring (5-2), self-locking elastic steel rod (5-3) and fixing seat (5-6 ) is encapsulated in the sleeve (5-4) as a whole, and one end of the sleeve (5-4) is sealed with a sealing plate (5-5). There is a threaded hole in the center of the sealing plate (5-5), and the fixing seat (5-6 ) threaded end passes through the central hole of the sealing plate (5-5), and is threadedly connected with the central t...

Abstract

An integrated one-way operation self-locking movable side guard plate fixing device comprises a slideway guide rod, a cylindrical spiral spring, a self-locking fixed type elastic steel bar, a sleeve, a seal plate, a fixed base, a catch bolt, a slideway guide rod fixing pin and a fixing pin, wherein one end of the elastic steel bar is fixed to the fixed base, and the other end of the elastic steel bar slides in a slideway of the slideway guide rod. When a jack is pushed horizontally to retreat, the elastic steel bar bounces off from a fixing position A and automatically moves to a fixing position B along the slideway, and then retreating and locking of a side guard plate are achieved; when the jack is pushed horizontally again, the elastic bar bounces off from the fixing position B and automatically moves to the fixing position A, and then stretching and locking of the side guard plate are achieved. When hydraulic supports conduct normal support on a working face, the self-locking fixed type elastic steel bar slides in the slideway freely under the elasticity of the spiral spring according to the distance between the supports, so that inter-support sealing is achieved. By the adoption of the device, automatic locking of the hydraulic support movable side guard plate is achieved.

Description

technical field [0001] The invention relates to an integrated one-way operation self-locking movable side guard plate fixing device, which is used for fixing the side guard plate of a hydraulic support. Background technique [0002] The movable side guard plate of the hydraulic support is mainly used for sealing between the top beam and the cover beam. Since there is a certain gap between the top beam and the cover beam between the two adjacent supports in actual work, the movable side guard plate of the top beam and the movable side guard plate of the cover beam are usually used to seal the frame between the top beam and the cover beam. Prevent leakage between racks. At present, the movable side guard plate is fixed by a pin shaft, and the fixing device mainly consists of a spring, a guide rod, a spring sleeve, a guide seat and a fixed pin shaft. The guide seat is welded on the movable side guard plate, and the guide seat guides the The rod is fixed, a spring sleeve is we...
