Abstract
The invention discloses a connection method of a hydraulic bracket capable of accomplishing movements such as ascending, descending, pushing and moving, which comprises the steps that: firstly, only two uprights separated at a certain distance are mounted under a horizontal top beam; in addition, a base with a pushing jack is horizontally arranged at the bottom of each upright; then the parts after connection are connected with a conveyor; secondly, a hydraulic system is configured; an emulsion pump is adopted, and connected with two operating valves through a main liquid supplying pipe and a main liquid return pipe; hydraulic oil circuits are arranged at the bottom ends of the uprights and connected with the hydraulic system through a safety valve and a hydraulic control one-way valve sequentially; and the uprights are arranged in two rows, and can tilt forward or backward, or are arranged in an inverted V manner or a crossed manner. The connection method has the benefits that the method has structural characteristics and properties of a supporting bracket and a shielding bracket, adapts to various requirements of top and bottom plates, and has the advantages of large supporting force, good topping property, good shielding property, large ventilation section, good stability and wide application scope.
Description
Technical field
The present invention relates to the hydraulic technique field, the hydraulic support method of attachment of actions such as relating in particular to and a kind ofly finish ascending, descending, push away, move.
Background technology
Hydraulic system has that power is large, operating pressure and the flow adjustability is good, heat can be brought back the advantages such as fuel tank, adopt hydraulic system to produce more power than other devices, under equal power, the volume of hydraulic means is little, lightweight, power density large, compact conformation; Simultaneously, the hydraulic means Comparision is steady because lightweight, inertia is little, reaction is fast, hydraulic means is easy to realize quick startup, braking and commutating frequently.At the working face of coal seam environment, generally select hydraulic shield support, Coal Seam Thickness Change then select greatly large the and anti-horizontal thrust of the scope of heightening strong and with the shield of wall supporting to improve the support force situation.Its structure generally comprises the body structures such as back timber, caving shield, base, and column satisfies the needs that support is heightened scope to increase impulse stroke.In order to improve advancing velocity, guarantee the immediate support to top board, adopt hydraulic system to divide at the installation position of coal-face by hydraulic support, middle hydraulic support is mounted in the support of all positions of coal-face except face end, divide by its form of structure, can be divided into three basic forms of it, that is: brace type, protected type and support shield type.Therefore, for adapting to the demand of different coal mining environment, raise the efficiency the fastness with the support part, existing bracket component structure and material are innovated seemed extremely important.
Summary of the invention
The purpose of this invention is to provide a kind of support force large, cut that the top performance is strong, barrier propterty good, the ventilation section large, good stability, be conducive to guarantee to the top board immediate support, can reduce finishing ascending, descending, the hydraulic support method of attachment of action such as pushing away, move, to solve many deficiencies of prior art of labour intensity.
Purpose of the present invention is come specific implementation by the following technical programs:
The hydraulic support method of attachment of the action such as a kind ofly finish ascending, descending, push away, move mainly is comprised of following steps:
⑴ at first only install two phases column across a certain distance below horizontal top bar, simultaneously, the bottom level that is positioned at column is provided with the base of advancing jack, more than part connect and be connected with conveyer after complete;
Then, the configuration hydraulic system arranges an emulsion pump and connects two by main feed pipe, main liquid back pipe respectively and handles valves, hydraulic circuit is set in the column bottom and is connected with hydraulic system through safety valve, hydraulic control one-way valve successively;
⑶ column wherein is set to two rows and can leans forward or hypsokinesis, perhaps is herringbone and arranges or arranged crosswise, and this two rows column all directly is supported on the back timber, when needs support rising supporting roof, regulate the plunger shaft that high-pressure emulsion enters column, liquid is returned in another chamber, and pushing piston rises, make the back timber that is connected with piston rod contact top board, when post fell in needs, high pressure liquid entered the rod end chamber of column, and liquid is returned in another chamber, force piston rod to descend, back timber breaks away from top board;
⑷ finish the reach of support and transporter by the advancing jack on the base, when the needs support moves forward, falls first the post unloading, then high pressure liquid enters the rod end chamber of advancing jack, and liquid is returned in another chamber, take conveyer as fulcrum, the cylinder body reach pulls to rib to whole support; When needs pushed away transporter, behind the stent support top board, high pressure liquid entered the plunger shaft of advancing jack, and liquid is returned in another chamber, take support as fulcrum, transporter is pushed to rib.
The beneficial effect that of the present inventionly finish ascending, descending, the hydraulic support method of attachment of action such as pushes away, moves is: the design feature and the performance that have brace type and shield concurrently, can adapt to various roof and floor conditions, have support force large, cut the advantages such as the top performance is strong, barrier propterty good, the ventilation section large, good stability, applied range, be conducive to improve the extraneous working effect of support, can improve the operation controllability, be conducive to guarantee to the top board immediate support, can reduce labour intensity.
The specific embodiment
The hydraulic support method of attachment of the actions such as the embodiment of the invention is described finishes ascending, descending, push away, move, its key step comprises:
⑴ at first only install two phases column across a certain distance below horizontal top bar, simultaneously, the bottom level that is positioned at column is provided with the base of advancing jack, more than part connect and be connected with conveyer after complete;
Then, the configuration hydraulic system arranges an emulsion pump and connects two by main feed pipe, main liquid back pipe respectively and handles valves, hydraulic circuit is set in the column bottom and is connected with hydraulic system through safety valve, hydraulic control one-way valve successively;
⑶ column wherein is set to two rows and can leans forward or hypsokinesis, perhaps is herringbone and arranges or arranged crosswise, and this two rows column all directly is supported on the back timber, when needs support rising supporting roof, regulate the plunger shaft that high-pressure emulsion enters column, liquid is returned in another chamber, and pushing piston rises, make the back timber that is connected with piston rod contact top board, when post fell in needs, high pressure liquid entered the rod end chamber of column, and liquid is returned in another chamber, force piston rod to descend, back timber breaks away from top board;
⑷ finish the reach of support and transporter by the advancing jack on the base, when the needs support moves forward, falls first the post unloading, then high pressure liquid enters the rod end chamber of advancing jack, and liquid is returned in another chamber, take conveyer as fulcrum, the cylinder body reach pulls to rib to whole support; When needs pushed away transporter, behind the stent support top board, high pressure liquid entered the plunger shaft of advancing jack, and liquid is returned in another chamber, take support as fulcrum, transporter is pushed to rib.
