Description
Technical field
The utility model relates to underground coal mine comprehensive mechanical coal mining technology, particularly a kind of pseudo-tiltedly fully-mechanized mining working shield support of bowing.
Background technology
Half-edge coal seam refers to that a kind of inclination angle is greater than 45 ° of coal seams, its have China distributed more widely, occurrence condition is complicated, the exploitation features such as difficulty is large.Because existing production technique falls behind, and domestic mine quantity is many.Therefore, in recent years, there are a lot of major accidents in China.Because steeply-inclined seam mining narrow space, working space angle of inclination are large, equipment back skating dangerous large, coal mine waste rock splashes etc., and potential threat is large, personnel's operating difficulties is large.Meanwhile, its seam construction complexity, fold, tomography have both at the same time, and operating environment is severe, production safety hidden danger is many, the comprehensive difficulty of adopting is large, high especially to the requirement of plant equipment compliance.Therefore, adopt existing fully mechanized mining and equipment, combining and adopting corollary equipment is that a great problem that the technology of adopting is applied to half-edge coal seam is combined in puzzlement because affected by equipment self gravitation gliding, for this reason, conventionally adopt the pseudo-tiltedly mode of bowing to arrange that fully-mechanized mining working changes the actual angle of inclination of corollary equipment, reduce downslide component to slow down falling tendency.In the pseudo-slanting face of bowing, the back timber of hydraulic shield support is usually designed to the structure of parallelogram, one group of parallel edges of this parallelogram is arranged to be parallel to the direction of the advance of the face, and another group parallel edges is arranged to be parallel to the direction of the scraper-trough conveyer parallel longitudinal of coal excavation apparatus.Support advances and can press staggered propulsion mode actualize by adjacent multistage propulsion mode and adjacent stent in groups.But in progradation, after the propelling of top support, can cause drop impact and extruding below support under spoil, a large amount of spoil impact extruded can cause support to glide, meanwhile, the spoil of whereabouts can cause below support passing clamping stagnation, causes and passes difficulty and pass the high defect of energy consumption.For this reason, need to improve this.
Summary of the invention
The purpose of this utility model is exactly for the deficiencies in the prior art, and a kind of pseudo-tiltedly fully-mechanized mining working shield support of bowing is provided, and with when bowing pseudo-tiltedly fully-mechanized mining working, reduces or eliminates support downslide hidden danger, alleviates support and passes clamping stagnation, reduces passing energy consumption.
For realizing aforementioned object, the utility model adopts following technical scheme.
A kind of pseudo-tiltedly fully-mechanized mining working shield support of bowing, this shield support consists of in pairs the first hydraulic support and the second hydraulic support, the back timber of this first hydraulic support and the second hydraulic support is overlooked profile and is trapezoidal, two trapezoidal parallelogram that are combined into, at the first hydraulic support and the second hydraulic support, lay when bowing pseudo-slanting face, one group of parallel edges of this parallelogram is parallel with advance of the face direction, the scraper-trough conveyer parallel longitudinal of its another group parallel edges and coal excavation apparatus, and the first hydraulic support is positioned at the second hydraulic support top, the trapezoidal upper base of the first hydraulic support is positioned at the direction of propulsion front end of the first hydraulic support, on the base of the first hydraulic support and the second hydraulic support, be equipped with for the propelling cylinder hinged with described scraper-trough conveyer.
The shield support that adopts this programme, consists of in pairs two hydraulic supports, and the back timber of the two is overlooked profile combination and formed a parallelogram, and a plurality of shield supports of the present utility model form the face timbering system that profile is parallelogram of overlooking.Scraper-trough conveyer advances and utilizes propelling cylinder to realize, and shield support advances past propelling cylinder and pulls respectively the second hydraulic support and the first hydraulic support to realize.In shield support progradation, first advance the second hydraulic support that is positioned at below, in the moving process of the second hydraulic support, this second hydraulic support adjacent two kidney-shapeds trapezoidal with back timber in the first hydraulic support of top become gradually away from, be can not form contact between the two, can not produce frictional resistance and hinder advance, only exist between the first hydraulic support with below, to form sliding friction and be connected, can effectively reduce the propelling energy consumption of support; Simultaneously, because trapezoidal the going to the bottom of the first hydraulic support is to be positioned at the first hydraulic support rear end in the trapezoidal longer end, it can increase the amount of stopping of spoil, reduces spoil whereabouts amount, thereby reduce spoil, fall to the impact of the first hydraulic support and extruding, can effectively reduce support downslide hidden danger.In addition, adjacent stent is staggered to be passed, and the sliding force of mobile support is born by adjacent stent, is difficult for causing sliding force to collect effect, can further guarantee supporting stability.
Preferably, the profile of overlooking of the base of described the first hydraulic support and the second hydraulic support has with corresponding back timber and overlooks the part that trapezoidal two waists of profile coincide.So that in arbitrary hydraulic support passing process, the hydraulic support that is positioned at below forms by back timber and base stopping that top hydraulic support downglide motion is inclined to simultaneously, further improves the stability of support system.
The utility model beneficial effect is compared with prior art, supporting is stable, moves frame smooth and easy, moves frame energy consumption low.
