Abstract

The invention relates to the technical field of hydraulic supports, and particularly relates to a water-rich soft rock geological condition hydraulic support pushing seat connecting device. The water-rich soft rock geological condition hydraulic support pushing seat connecting device comprises a pin shaft, a stop block and a fastener; a first end of the pin shaft is provided with a protruding part, and the stop block is arranged at a second end of the pin shaft through the fastener; and the stop block is arranged around the pin shaft, a limiting groove is formed in one of the pin shaft and the stop block, a limiting protrusion is arranged on the other one of the pin shaft and the stop block, and the limiting protrusion is clamped in the limiting groove. The pin shaft is limited through the stop block, the stop block and the pin shaft are matched through the limiting groove and the limiting protrusion, and the stop block and the pin shaft are connected through the fastener, so that the installation of the pin shaft has high structural strength. The traditional locking design is broken through, a vertical pin is locked only by an upper stop pin to prevent outward movement, and the locking strength and reliability are greatly improved.

Description

technical field [0001] The invention relates to the technical field of hydraulic supports, in particular to a hydraulic support push seat connecting device for geological conditions of rich water and soft rock. Background technique [0002] The soft rock strata in the water-rich soft rock mining area are "weakly cemented, low-strength, rich in water, and easy to hydrolyze". . [0003] The original push seat connection device of the fully mechanized mining face hydraulic support adopts vertical pins to be installed from top to bottom, and U-shaped pins or square pins are used for locking. When the bracket adopts the timely support method, the operation steps are as follows: After coal mining—retract the side guard plate—lower the frame—lift the bottom—moving the frame—raise the frame—stop the liquid supply in the upper cavity of the side push jack—push slip. In the fully mechanized coal mining face, the bottom pressure push rod is lifted during the moving operation of the ...
