一种充填隔离架体及分体式充填液压支架
By designing a split-type filling hydraulic support, with a movable front frame and adjustable filling isolation height, the problems of short coal mining time and low isolation efficiency caused by rigid connections in traditional supports are solved. This achieves flexible adjustment and stable support, reduces costs and improves operational efficiency.

AI Technical Summary
The front and rear sections of the traditional paste-filling hydraulic support are rigidly connected, which prevents the front section from advancing during the paste solidification period, limiting the coal mining operation time, resulting in low isolation efficiency and high cost. Furthermore, the filling isolation height adjustment of the rear section is not flexible enough, and the paste support stability is insufficient.
The design features a split-type hydraulic filling support with a movable front frame and adjustable filling isolation height. The upper and lower isolation bodies are moved vertically and backward via hydraulic cylinders. Combined with the nested structure of the L-shaped base and guide seat, it achieves stable support and flexible adjustment. Rubber isolation strips are used to reduce damage to the isolation cloth, and the drawer-type structure of the sliding hydraulic cylinder and sliding groove ensures coaxiality.
It enables the forward movement of the front frame during the solidification of the paste, improving coal mining operation time and isolation efficiency, reducing costs, and allowing for flexible adjustment of the filling and isolation height according to the longwall face, ensuring stable support of the paste and precise movement of the equipment.
