Abstract
The utility model discloses a top coal caving hydraulic support base with a backward-pusher device. The top coal caving hydraulic support base with the backward-pusher device comprises a hydraulic support base body, a backward-pusher oil cylinder and a scraper conveyer chute, wherein the backward-pusher oil cylinder is arranged in a column nest blocking box of the hydraulic support base body and is filled with liquid, a liquid inlet is formed in a piston rod, the piston rod is hinged to a connecting base in the column nest blocking box, and a cylinder body is hinged to the scraper conveyer chute through a round-link chain or a pull rod. The top coal caving hydraulic support base with the backward-pusher device has the advantages that the structure is compact, space between every two adjacent top coal caving hydraulic support bases is saved, and mutual interference of bases due to the fact that the gap between bodies of supports is too small is prevented; meanwhile, due to the fact that the backward-pusher oil cylinder is arranged in the column nest blocking box of the hydraulic support base body, gangue between the bodies of the supports can not be in contact with the backward-pusher oil cylinder, and the backward-pusher oil cylinder can not be damaged. The top coal caving hydraulic support base with the backward-pusher device is suitable for a top coal caving support with space between side faces of a base being small and a space existing on the rear portion of a column nest.
Description
Technical field
The utility model relates to caving roof coal hydraulic support, especially relates to the Base of Cover Caving Coal Hydraulic Supports that moves rear slip device.
Background technology
At present, in coal mining process, caving roof coal hydraulic support slips operation after need to moving.Caving roof coal hydraulic support is generally equipped with and moves rear slip device, is arranged in base exterior side, and base slips oil cylinder and scratch board conveyor chute and is connected to form the system of slipping after moving by gudgeon, after moving.The deficiency that above-mentioned Base of Cover Caving Coal Hydraulic Supports exists is: be placed on the rear slip device of moving of base side and occupy larger space, the oil cylinder that slips after moving is easily squeezed bad by spoil between frame.
Summary of the invention
The utility model object is to provide a kind of Base of Cover Caving Coal Hydraulic Supports with moving rear slip device.
For achieving the above object, the utility model is achieved through the following technical solutions:
Base of Cover Caving Coal Hydraulic Supports with moving rear slip device described in the utility model, comprises hydraulic support foundation, slips oil cylinder, scratch board conveyor chute after moving; The oil cylinder that slips after described moving is arranged in the needling shelves casing of hydraulic support foundation; The oil cylinder that slips after described moving is interior fluid-filling structure, and inlet is opened on piston rod, and the Connection Block in piston rod and needling shelves casing is hinged, and it is hinged that cylinder body passes through round-link chain or pull bar and scratch board conveyor chute.
The utility model advantage is compact conformation, has saved the space between adjacent Base of Cover Caving Coal Hydraulic Supports, while preventing from moving frame, between support frame, causes to such an extent that base interferes with each other because gap is little.Meanwhile, the oil cylinder that slips after moving is arranged in the needling shelves casing of described base, and between frame, spoil cannot be in contact with it, and can not cause damage to it.The utility model is applicable to the sublevel caving hydrau lic support that base lateral space is narrow and small and needling rear portion has living space.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the plan structure schematic diagram of Fig. 1.
Fig. 3 is cylinder body described in the utility model by pull bar and the hinged structural representation of scratch board conveyor chute.
The specific embodiment
As shown in Figure 1, 2, 3, the Base of Cover Caving Coal Hydraulic Supports with moving rear slip device described in the utility model, comprises hydraulic support foundation 1, slips oil cylinder 2, scratch board conveyor chute 4 after moving; The oil cylinder 2 that slips after described moving is arranged in the needling shelves casing of hydraulic support foundation 1; After described moving, slip oil cylinder 2 for interior fluid-filling structure, and inlet is opened on piston rod, and the Connection Block 5 in piston rod and needling shelves casing is hinged by bearing pin, and cylinder body is hinged by bearing pin with scratch board conveyor chute 4 by round-link chain 3 or pull bar 6.
The utility model motion process is: the oil cylinder 2 that slips after moving is regained, and slips action by round-link chain 3 or pull bar 6 after pulling rear portion scratch board conveyor chute 4 to realize to move; When support moves frame, the oil cylinder 2 that slips after moving is pulled out by the scratch board conveyor chute 4 at rear portion.After moving in whole process, slip the most of structure of oil cylinder 2 at base 1 internal motion, and between frame, spoil cannot be in contact with it, and can not cause damage to it.
