Abstract
The utility model discloses a hydraulic prop with a long stroke. A hydraulic oil outlet of the existing hydraulic prop is arranged at the upper end, so that the hydraulic prop needs large pressure when working, consumes much energy and is low in working speed. The hydraulic prop with the long stroke comprises a cylinder (1) of which the hydraulic oil outlet is arranged at the lower end; a plunger cylinder (3) with a restoring spring (2) is inserted into the cylinder; the upper end of the plunger cylinder is connected with a top cover bottom plate (4); the top cover bottom plate is connected with a hinge top cover assembly (5) and a spherical support (6); a base (7) is connected with the bottom part of the cylinder; a handlebar body (8) is connected with the upper part of the cylinder; the lower part of the cylinder is connected with a triangular valve assembly, and the lower end of the plunger cylinder is connected with a piston (9). The hydraulic prop with the long stroke is used for coal mining.
Description
Technical field:
The utility model relates to a kind of long stroke hydraulic pillar.

Summary of the invention:
The purpose of this utility model provide a kind of hydraulic pressure oil-out in the lower end, long stroke hydraulic pillar easy to maintenance.
Above-mentioned purpose realizes by following technical scheme:
A kind of long stroke hydraulic pillar, its composition comprises: the hydraulic pressure oil-out is at the oil cylinder of lower end, insert the plunger tube with back-moving spring in the described oil cylinder, described plunger tube upper end connects the top cover base plate, described top cover base plate connects hinged top lid composite member and spherical bearing, and described oil cylinder bottom connects base, and described oil cylinder top connects handle body, described oil cylinder bottom connects the triangle vavle composite member, and described plunger tube lower end connects piston.
Described long stroke hydraulic pillar, the column casing end socket is equipped with on described plunger tube top, described column casing end socket upper end connects described spherical bearing by pin, described column casing end socket lower end spring link, described spring link connects described back-moving spring, described back-moving spring connects the lower spring link, and described lower spring link connects described base.
Described long stroke hydraulic pillar, O RunddichtringO and sealing anti-extrusion ring are housed between described column casing end socket and the described plunger tube, O RunddichtringO and sealing anti-extrusion ring are housed between described plunger tube and the described piston, between described plunger tube and the described oil cylinder spacing wire loop is housed, between described oil cylinder and the described piston piston guide ring is housed, leather cup anti-extrusion ring and y-type seal ring, between described plunger tube and the described top cover base plate top cover is housed and is connected steel wire, between described oil cylinder and the described handle body handgrip is housed and is connected steel wire, post guide ring alive and dust ring are housed between described handle body and the described plunger tube, between described column casing end socket and the described pin packing ring are housed.
Described long stroke hydraulic pillar, described triangle vavle composite member comprises oil inlet pipe, and described oil inlet pipe one end connects described oil cylinder, and the described oil inlet pipe other end connects the triple-use valve seat.
Beneficial effect:
1. the utility model stroke is long, and is applied widely, simple in structure, easy to maintenance, and the life-span is long, durable, can be used in coal face variation coal-face greatly.
2. the utility model can substitute the existing pillar of plurality of specifications and model, and this product has reduced workman's labour intensity, good integrity, and no-welding-seam, intensity height, the anti-performance that fractures is strong, safe and reliable.
3. piston of the present utility model adopts O RunddichtringO and sealing anti-extrusion ring, good sealing effect, and large, the anti-revisionist rate of intensity is low.
4. the utility model adopts dust ring to seal, and makes the good sealing effect between handle body and the plunger tube.
5. the utility model adopts the hydraulic pressure oil-out in the lower end of oil cylinder, fuel-displaced convenience, and required pressure is low, saves the energy.
