An isolation device for filling stents

Abstract

The invention belongs to the technical field of hydraulic filling brackets, and in particular relates to an isolation device for filling brackets, which comprises a material injection port, an isolation plate and side shields arranged on both sides of the isolation plate, wherein the isolation plate includes a hydraulic The pins of the bracket baffle jack are connected to the ears, the material injection port penetrates the isolation plate, the isolation plate is connected with a first telescopic piece for pushing the side shield, and the isolation plate is embedded with a telescopic plate, so A telescopic plate jack is connected between the isolation plate and the telescopic plate, a second telescopic piece is fixed on the isolation plate, a push plate is arranged at the free end of the second telescopic piece, and both sides of the telescopic plate slide respectively A telescopic plate side plate is inserted and connected, and the telescopic plate side plate is movably connected between the push plate and the side guard plate. In the present invention, by arranging the push plate and the side guard plate, and cleverly arranging the side plate of the telescopic plate on the push plate and the side guard plate, no gap is left at the side edge of the isolation device, and the sealing performance of the isolation device is greatly improved. .

Description

technical field [0001] The invention belongs to the technical field of hydraulic filling brackets, and particularly relates to an isolation device for filling brackets. Background technique [0002] At present, the problem of isolation and plugging of the to-be-filled area is one of the main difficulties restricting the paste filling and mining technology. For this reason, the existing fully mechanized mining support is provided with an isolation device for sealing the filling slurry. However, the existing isolation device telescopic plate does not have side plates or is provided with side plate covers, which cannot achieve lateral expansion and vertical expansion at the same time, resulting in a gap at the side edge of the isolation device, which seriously restricts the sealing performance of the isolation device. SUMMARY OF THE INVENTION [0003] In order to solve the problems raised in the above background art. The invention provides an isolation device for filling the...

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.
