Description
Technical field
The utility model relates to underground coal mine filling mining equipment, especially slips the mechanical puddling device of head, slipping tail filling space for primary waste filling production practice.
Technical background
In recent years, along with country is to the popularization of improvement of the ecological environment requirement and mine filling production practice, filling mining technique is constantly perfect, filling mining equipment constantly upgrades, based on the primary waste filling technique of the mine of tamping filling support, greatly improve filling mining efficiency, but due to the scrapper conveyor motor at filling support rear portion, reduction box affects, ramming device cannot be installed within the scope of three supports of scrapper conveyor termination, filling-up mechanically cannot be realized, need to take manually to build spoil bag mode, operation holding time is long, technique is loaded down with trivial details, efficiency is low, take personnel many, personnel will enter empty top zone operation, be unfavorable for safety in production, the raising of serious restriction filling mining efficiency.
Summary of the invention
In order to solve the mechanized filling problem of above-mentioned scrapper conveyor end, the utility model provides a kind of coal mine waste rock filling ramming mechanism of all-hydraulic control.
A kind of coal mine waste rock filling ramming mechanism, it is characterized in that, it is provided with major and minor two free bearings at the base rear portion of filling support, wherein, main free bearing connects a upper two telescopic tamping oil cylinder by cross connecting piece, and the external part of tamping oil cylinder connects upper tamping head; Secondary free bearing connects a thruster oil cylinder, and the external part of thruster oil cylinder is hinged on the one-level cylinder body of tamping oil cylinder; The one-level cylinder body of tamping oil cylinder be also provided with free bearing above, connect a hoist cylinder by this free bearing, the other end of hoist cylinder is hinged on the tail boom of filling support; Power is provided by hydraulic power unit during work, by operating valve group, promoting reversal valve makes emulsion enter reversible lock by flow divider-combiner and coordinate each cylinder efficient, realizes the pushing of tamping head, lifting, sidesway action, thus by the filling waste rock tamping of scrapper conveyor end.
Above-mentioned major and minor two free bearings can be separately positioned on the base rear portion of adjacent two frame filling supports.
The one-level cylinder body effective length 1.5m of above-mentioned two telescopic tamping oil cylinder, secondary cylinder body effective length 1.3m, overall stroke reaches 2.8 meters, tamping thrust 120 tons.
The effective length 0.8m of above-mentioned thruster oil cylinder, thruster stroke 0.7m, rotate and pass angle 45 °.
During work, after obturation drops to certain altitude, by operating valve, hoist cylinder is shunk the adjustment tamping elevation angle, the anglec of rotation of fore side push oil cylinder adjustment simultaneously, operation tamping oil cylinder carries out tamping; After tamping head reaches position, by operating valve, tamping oil cylinder is regained, stretch out hoist cylinder simultaneously and set level the elevation angle, regain thruster oil cylinder levelling ramming mechanism.When spoil drops to certain altitude again, repeat aforesaid operations, by repeatedly operating ramming mechanism, until ram goaf filling height, density pressure to specifying requirement.
The utility model achieves the termination filling-up mechanically of mine primary waste filling technique, the personnel that stopped enter goaf construction, eliminate goaf cash filling of manually slitting to construct the potential safety hazard brought, expand and smash cash scope, the Full Ratio of termination triangle is made to bring up to present more than 118% by original 60%, improve Full Ratio, promote the reasonable parallel operations of inter process, improve filling mining efficiency.
