Abstract
The invention discloses a hydraulic supporting-shielding bracket structure for a coal face, which consists of a front beam, a top beam, a shielding beam, a base, a pushing jack and uprights that are mounted in place respectively, wherein the shielding beam for preventing gangue in a gob from entering a working space is arranged at one end of a main beam; the upper end of the shielding beam is articulated with the top beam; the lower end of the shielding beam is connected with the base through a front and back connecting rod; 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 two rows of uprights are supported on the top beam directly. Or, the uprights in the back row are supported on the shielding beam, and the uprights in the front row are supported on the top beam. The structure has the benefits that the structure has the structural characteristics and properties of a supporting bracket and a shielding bracket; meets the requirements of various top and bottom plates; and has the advantages of large supporting power, good topping property, good shielding property, large ventilation section, good stability, wide application scope and the like.
Description
Technical field
The present invention relates to the hydraulic technique field, relate in particular to a kind of coal-face hydraulic pressure support shield structure.
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 the coal-face hydraulic pressure support shield structure of labour intensity, to solve many deficiencies of prior art.
Purpose of the present invention is come specific implementation by the following technical programs:
A kind of coal-face hydraulic pressure support shield structure mainly is comprised of following steps:
⑴ at first be comprised of front-axle beam, back timber, caving shield, base, advancing jack, column and be respectively installed to the position;
⑵ arrange a caving shield at girder one end and enter working space to block the goaf spoil, and upper end and the back timber of this caving shield are hinged, and the lower end is connected with base by front-rear linkage;
⑶ column is set to two rows and can leans forward or hypsokinesis, is perhaps that herringbone is arranged or arranged crosswise, and this two rows column all directly is supported on the back timber, and perhaps wherein rear row's upright supports is on caving shield, and front-seat column then is supported on the back timber;
⑷ arrange movable side protection plate in the both sides of support and seal between with frame, and back timber is set to 3.0mm.
The beneficial effect of coal-face hydraulic pressure support shield structure of the present invention 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 described coal-face hydraulic pressure support of embodiment of the invention shield structure, its key step comprises:
⑴ at first be comprised of front-axle beam, back timber, caving shield, base, advancing jack, column and be respectively installed to the position;
⑵ arrange a caving shield at girder one end and enter working space to block the goaf spoil, and upper end and the back timber of this caving shield are hinged, and the lower end is connected with base by front-rear linkage;
⑶ column is set to two rows and can leans forward or hypsokinesis, is perhaps that herringbone is arranged or arranged crosswise, and this two rows column all directly is supported on the back timber, and perhaps wherein rear row's upright supports is on caving shield, and front-seat column then is supported on the back timber;
⑷ arrange movable side protection plate in the both sides of support and seal between with frame, and back timber is set to 3.0mm.
Claims (1)
