Problems solved by technology
However, the telescopic plate of the existing isolator is not provided with side panels or is provided with side panels to cover the side panels, which cannot achieve both horizontal and vertical expansion at the same time, resulting in gaps left on the side edges of the isolation device, which seriously restricts the sealing performance of the isolation device.

The invention belongs to the technical field of hydraulic filling brackets, and particularly relates to an isolation device for filling brackets. The device comprises an injection port, an isolation plate and side protecting plates arranged at both side ends of the isolation plate. The isolation plate comprises a pin lug used for being connected with a hydraulic bracket baffle jack, the injectionport penetrates through the isolation plate, the isolation plate is connected with a first telescopic part for pushing the side protecting plates, a telescopic plate is embedded into the isolation plate, a telescopic plate jack is connected between the isolation plate and the telescopic plate, a second telescopic part is also fixedly arranged on the isolation plate, a push plate is arranged at a free end of the second telescopic part, telescopic plate side plates are slidably inserted into both sides of the telescopic plate respectively, and the telescopic plate side plates are movably connected between the push plate and the side protecting plates. According to the device, through the arrangement of the push plate and the side protecting plates and the arrangement that the telescopic plate side plates are cleverly arranged between the push plate and the side protecting plates, no gap remains at the side edge of the isolation device, and the leakproofness of the isolation device is greatly improved.
Description
technical field [0001] The invention belongs to the technical field of hydraulic filling brackets, and in particular relates to an isolation device for filling brackets. Background technique [0002] At present, the problem of isolation and plugging in the area to be filled is one of the main difficulties restricting the paste filling mining technology. For this reason, the existing fully mechanized mining support is equipped with an isolation device for sealing filling slurry. However, the expansion plate of the existing isolator is not provided with side panels or is provided with side panels to cover the side panels, which cannot realize both lateral expansion and vertical expansion at the same time, resulting in gaps left at the side edges of the isolation device, which seriously restricts the sealing performance of the isolation device. Contents of the invention [0003] In order to solve the problems raised in the above-mentioned background technology. The present i...
