Description
Technical field
The present invention relates to a kind of gear cash device and method of coal-face, especially a kind of gear cash device and method being applicable to the high-dipping coal-face of underground coal mine raising gear cash effect.
Background technology
Mine under high_dipping face condition, in whole manufacturing process, there will be that coal and rock that coal-winning machine cuts off is accelerated to glide or roll along the incline direction of work plane on drag conveyor, the spoil on the upper cover plate of sidewalk and the spoil on machine road easily alter mutually and fly into the situations such as spoil in sidewalk, bring great threat to the safety of work plane staff and equipment.
In order to ensure that work plane personnel and device security normally work, according to specific works face actual conditions, rigidity gear cash protective screening or soft waste rock blocking protective screening are installed in present stage many utilizations in support termination.Rigidity gear cash method use blocking effect good, be conducive to ventilating and operating personnel can obtain good sight line, but meet when bulk bastard coal impacts due to rigidity gear cash protective screening and slow down ability, easily cause protective screening deformed damaged; Soft waste rock blocking protective screening effectively can stop and alleviate the impact force of bastard coal block; but because area large (grid is closeer) affects the sight line of face-airing and workman; and for not having suitable gear cash device between machine road and sidewalk and set cap can only being relied on to ensure the safety at workman top, the side direction for spoil then has no safeguard measure.
In sum, it is single to there is this use in the gear cash method of current high-dipping coal-face, can not carry out omnibearing protection and gear cash weak effect to whole work plane.
Summary of the invention
Technical problem: the object of the invention is to overcome the weak point in technology, provide that a kind of structure is simple, convenient operation, protection safety, effective high-dipping coal-face gear cash device and method.
Technical scheme: the gear cash device of high-dipping coal-face of the present invention, comprise the gear cash protector be hinged on high_dipping face hydraulic support forestope, the telescopic waste rock board in sidewalk be located on the brace summer of high_dipping face hydraulic support, the high_dipping face hydraulic support foundation inside the telescopic waste rock board in sidewalk is provided with gate-type waste rock board, described gear cash protector comprises the rigidity gear cash protective screening and soft waste rock blocking protective screening alternately arranged, rigidity is kept off cash protective screening and is respectively equipped with first hydraulic jack be connected with forestope inside soft waste rock blocking protective screening, the telescopic waste rock board in described sidewalk comprises the flexible waste rock board be hinged on high_dipping face hydraulic support brace summer, second hydraulic jack be connected with brace summer is provided with in the middle part of flexible waste rock board, flexible waste rock board comprises one-level waste rock board and is nested in the secondary waste rock board in one-level waste rock board, the 3rd is provided with between one-level waste rock board and secondary waste rock board, four hydraulic jack, described gate-type waste rock board comprises the bearing pin be fixed on high_dipping face hydraulic support foundation, be located at waste rock board on bearing pin, the rear side of waste rock board is provided with the support hydraulic pressure jack that can make waste rock board swing at a right angle.
Use the gear cash method of the high-dipping coal-face of said apparatus, the forestope every seven frame high_dipping face hydraulic supports alternately installs rigidity gear cash protective screening and soft waste rock blocking protective screening; The pavement railing plate of normally open is installed on the brace summer of every frame high_dipping face hydraulic support simultaneously, and in high_dipping face hydraulic support sidewalk every five frame supports base on the gate-type waste rock board of one normally open is installed; When coal-winning machine coal cutting, the rigidity gear cash protective screening and soft waste rock blocking protective screening alternately installed is packed up one by one with coal cutting traffic direction, after coal-winning machine back roll cuts, open the rigidity gear cash protective screening and soft waste rock blocking protective screening alternately installed one by one, and close the pavement railing plate of normally open one by one; When moving frame, one by one the pavement railing plate moving frame is packed up, after support moves on to position, open pavement railing plate in time.
Beneficial effect: owing to have employed such scheme, utilize, on hydraulic support forestope, rigidity gear cash protective screening and soft waste rock blocking protective screening are alternately installed, and telescopic pavement railing plate is installed on hydraulic support brace summer and method that gate-type waste rock board combines is installed on bracket base thus to work plane omnibearing protection, be combined in and hydraulic support brace summer install telescopic pavement railing plate and gate-type waste rock board is installed on bracket base, thus well relaxed the impact force of bulk spoil, add the life-span of rigid baffle; Do not affect again the ventilation of coal-face and the sight line of workman simultaneously, realize the comprehensive gear cash of whole high_dipping face.Its structure is simple, easy to operate, for the personnel of coal-face work and equipment provide safety assurance, has practicality widely.
