Description
Technical field
The utility model relates to a kind of integral top beam hyperstatic hydraulic support, is particularly useful for the roof timbering of coal-face under the coal mine, also is applicable to the occasion that other needs supporting.
Background technology
Mine support equipment is one of imperative equipment under the coal mine.The support apparatus that uses in the colliery mainly contains the hydraulic support of quadric chain, also claim four connecting rod hydraulic supports, the upper and lower movement locus of four connecting rod hydraulic support back timbers is a lemniscate, see specifically that the Coal Industry Press published in 1993 " the 5th piece of chapter 3 of coal mine support handbook the 3rd joint content and publishing house of China Mining University in Eleventh Five-Year Plan institution of higher education national planning teaching material " mining machinery " book of publishing in 2010 about the support apparatus content.Four connecting rod hydraulic supports originate in the fifties in last century, and the sixties, technology entered the stage of ripeness, begin to introduce the China's coal-mine industry end of the seventies.The problem that four connecting rod hydraulic supports exist: one: because its back timber is a lemniscate movement locus, to redesign one to one during each the use, and carry out trial-production and the Performance Detection of sample frame, by detect qualified after, just can obtain peace standard card book, just can carry out the manufacturing of hydraulic support at last, such cyclic process, at least half a year, could give the colliery equipment more than 1 year at most and use, efficient is quite low; Two: because the design feature of four connecting rod hydraulic supports, it can't realize modularized design, can only carry out single Analysis of Nested Design and production one to one, the design work amount is heavy, production cycle is long, and labour intensity is big, the cost of production height, the fringe cost of intermediate link is higher, has had a strong impact on the promotion rate of China's hydraulic support and has promoted the use of face.Three: because four connecting rod hydraulic supports must carry out single Analysis of Nested Design and the manufacturing one to one, bring very big difficulty for modularization, standardization, seriation, integrated production, can't carry out the large-scale production of component, more impossiblely carry out integrated assembling.Therefore, based on the problem of existing four connecting rod hydraulic supports, change know-why and the technical pattern of existing hydraulic support, have important practical significance and historic significance.
Summary of the invention
The purpose of this utility model is at the problem that exists in the prior art, the integral top beam hyperstatic hydraulic support that a kind of compact conformation is provided, alleviates miner's labour intensity, improves miner's safety, reduces production costs, is easy to promote, support effect is good.
For achieving the above object, integral top beam hyperstatic hydraulic support of the present utility model, comprise hydraulic control valve group, push unit, push unit one side connects drag conveyor, described push unit opposite side is provided with base, base is provided with back timber, be provided with 8 between base and the back timber and be the netted hydraulic vertical prop that intersects symmetric arrangement, the base afterbody is provided with raises frame, the front end of back timber is provided with extensible canopy, back timber has the extensible canopy jack that links to each other with extensible canopy, and extensible canopy jack two ends are hinged with extensible canopy and back timber respectively; Be hinged with face guard on the extensible canopy, face guard is provided with the face guard jack that makes its swing, and the face guard jack is hinged and connected with face guard and extensible canopy respectively; Described back timber afterbody is hinged with tail boom, and the upper end of tail boom lower end and connecting plate is hinged, and the lower end of connecting plate is with to raise frame hinged; Described base is provided with gap bridge, and the valve pack support of installing the hydraulic control valve group is installed on the gap bridge.
Described back timber, extensible canopy, face guard, tail boom, connecting plate, base, raise frame and be welded by steel plate or shaped steel; Described hydraulic control valve group is made up of one group of manual operating valve or electric liquid Remote control valve, one way valve, pipe fitting and seal; Described face guard is scalable face guard.
Beneficial effect: the utility model integral top beam hyperstatic hydraulic support, the upper and lower movement locus of integral top beam is straight line, can realize modularized design, seriation, standardized production, integrated assembling, the maximum height hydraulic support can cover the hydraulic support than low height in the module, has reduced intermediate link, has improved production efficiency, reduce cost of production, can realize the quick popularization of hydraulic support.According to coal mine roof plate pressure with some modules highly are set, the some identical working resistances of each modular design but highly different hydraulic support specifications, and the height specification meets the seriation standard, cover the principle of lower height support with high trestle, the trial-production of maximum height specification sample frame, sample frame are detected, pacify mark evidence obtaining work, capped than the small-sized support, reduced middle production link, shortened the production cycle.Major advantage has:
(1) the utility model integral top beam hyperstatic hydraulic support can be realized seriation, standardized production, component are made standard component, the support that can form the differing heights specification of standard series according to the coal seam situation, the colliery needs any specification just to select any specification, carry out integrated Assembling Production after choosing, improved production efficiency;
(2) the utility model integral top beam hyperstatic hydraulic support can be accomplished scale production, and each component can form production line, produces quickly and efficiently on a large scale realizing, reaches the purpose that satisfies colliery large-scale promotion hydraulic support;
(3) the utility model integral top beam hyperstatic hydraulic support can be applicable to fully-mechanized mining working, also can be used in blast mining face, and it is simple in structure, and good stability is easy to use and reliable, has practicality widely.
