Abstract
The utility model discloses a novel linear supporting hydraulic support, which mainly comprises a top beam, top beam side guard plates, hydraulic struts, a gangue blocking plate, an upper stabilizing rod, a lower stabilizing rod, a base, a push cylinder, a push rod and the like. The hydraulic support is characterized in that: the hydraulic struts are supported between the base and the top beam; the upper and lower cavities of the hydraulic struts are connected with hydraulic valves, so that the upper and lower cavities of the hydraulic struts are simultaneously self-locked; the upper stabilizing rod is connected to the top beam, the lower stabilizing rod is connected to the base, and the upper stabilizing rod and the lower stabilizing rod are box-type bodies and are mutually telescopically sleeved; and the push rod is arranged in the middle of the base, and the push cylinder is connected between the base and the push rod. Because the upper and lower cavities of the hydraulic struts are connected with the hydraulic valves, stability of the hydraulic support can be effectively controlled.
Description
Technical field
The utility model relates to the hydraulic support technology, relates to coal mining supporting field especially
Background technology
Fig. 1 is the structural representation of prior art straight support formula hydraulic support, comprise back timber 1, back timber side guard board 2, hydraulic prop 3, waste rock board 4, cut top balancing cylinder 5, go up stabiliser bar 6, down stabiliser bar 7, base 8, pass compositions such as oil cylinder 9, push rod 10.Though this of prior art kind of hydraulic support alleviates weight support frame, reduces cost, still there is following defective in it:
(1) adopts and to cut top balancing cylinder 5 and cause support to go up and down not block phenomenon.
(2) employing is cut top balancing cylinder 5 and is caused the complicated misoperation of supporting structure.
Summary of the invention
The utility model technical problem to be solved is to carry the novel linear hydraulic chock-shield support; Mainly comprise back timber, back timber side guard board, hydraulic prop, waste rock board, go up compositions such as stabiliser bar, following stabiliser bar, base, passing oil cylinder, push rod; It is characterized in that: lean on hydraulic prop to support between said base and the said back timber; The upper and lower cavity of described hydraulic prop is connected with hydraulic valve and makes the self-locking simultaneously of hydraulic prop upper and lower cavity; The described stabiliser bar of going up is connected on the back timber, and following stabiliser bar is connected on the base, and last stabiliser bar is the flexible each other suit of box body with following stabiliser bar; In the middle of the described base push rod is installed, is connected with the passing oil cylinder between described base and the push rod.
Described novel linear hydraulic chock-shield support adopts and leans on hydraulic prop to support between base and the back timber; The described stabiliser bar of going up is connected on the back timber; Following stabiliser bar is connected on the base; Last stabiliser bar and following stabiliser bar are box body telescopic assembling structure each other, make support vertical and horizontal stable equilibrium stable, the upper and lower cavity that described hydraulic prop supports be connected with straight support formula hydraulic support that hydraulic valve overcome prior art go up and down not Ka and misoperation etc. state defective.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done and to be further described.
Fig. 1 is the structural representation of prior art straight support formula hydraulic support;
Fig. 2 is the structural representation of the utility model novel linear hydraulic chock-shield support.
The specific embodiment
To combine accompanying drawing that the utility model is done further to detail below, with purpose, scheme and the effect of further understanding the utility model, but not as the restriction to the utility model claim protection domain.
The utility model technical problem to be solved is to provide the novel linear hydraulic chock-shield support; Mainly comprise back timber 10, back timber side guard board 20, hydraulic prop 30, waste rock board 40, go up compositions such as stabiliser bar 50, following stabiliser bar 60, base 70, passing oil cylinder 80, push rod 90; It is characterized in that: lean on hydraulic prop 30 to support between said base 70 and the said back timber 10; The upper and lower cavity of described hydraulic prop 30 is connected with hydraulic valve, makes the self-locking simultaneously of hydraulic prop 30 upper and lower cavities, and the described stabiliser bar 50 of going up is connected on the back timber 10; Following stabiliser bar 60 is connected on the base 70; Last stabiliser bar 50 is the flexible each other suit of box body with following stabiliser bar 60, in the middle of the described base 70 push rod 90 is installed, and is connected with between described base 70 and the push rod 90 and passes oil cylinder 80.
The operating process of support: 1, coal-winning machine coal cutting; 2, hydraulic prop 30 falls; 3, pass cylinder 80 and reel frame; 4, rise hydraulic prop 30; 5, pass cylinder 80 and stretch the scraper plate machine 100 of passing;
Though the utility model discloses as above with a preferred embodiment; Right its is not in order to limit the utility model; Under the situation that does not deviate from the utility model spirit and essence thereof; Those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
