The specific embodiment
In conjunction with Fig. 1, the mining single wire winding type high pulling torque hydraulic anti-explosive hoist of present embodiment one, product main gear mode adopts many explosion-proof alternating-current motor/AC motors of squirrel-cage directly to drive many high pressure Variable plunger pumps, through the hydraulic closed loop to main shaft device one end, drive many constant displacement hydraulic motors and variable hydraulic motor simultaneously, again by the rotation of epicyclic reduction gear drive shaft and reel, finish lifting process lifting, transfer, accelerate, slow down, various operating modes such as parking, emergency braking.Realization is imported a plurality of torques simultaneously by main shaft device one end, has solved hydraulic anti-explosive hoist to high-power, big specification, high pulling torque, promote the difficult problem of length direction development greatly.Wherein, the hydraulic anti-explosive hoist mechanics also comprises, single (two) tube main shaft 1, base 3 and the disc brake device 4 that main shaft is braked.
In conjunction with Fig. 2, the mining single wire winding type high pulling torque hydraulic anti-explosive hoist of present embodiment two, product main gear mode adopts many explosion-proof alternating-current motor/AC motors of squirrel-cage directly to drive many high pressure Variable plunger pumps, the equidistant hydraulic closed loop of warp is to the main shaft device two ends, drive many constant displacement hydraulic motors and the variable hydraulic motor of two ends equal amount simultaneously, again by the rotation of epicyclic reduction gear drive shaft and reel, finish lifting process lifting, transfer, accelerate, slow down, various operating modes such as parking, emergency braking.Can realize by main shaft device two ends input torque simultaneously, solve hydraulic anti-explosive hoist to high-power, big specification, high pulling torque, promote the difficult problem of length direction development greatly.Wherein, the hydraulic anti-explosive hoist mechanics also comprises, single (two) tube main shaft 1, base 3 and the disc brake device 4 that main shaft is braked.
In order to satisfy the requirement that high pulling torque promotes, need to adopt a plurality of HM Hydraulic Motor combineds action, to obtain bigger input torque, because the restriction of existing gig physical construction, usually can only arrange 2 ~ 8 HM Hydraulic Motor at main shaft device one end, not satisfy the requirement that high pulling torque promotes.Present embodiment adopts the clino-axis type axial plunger of arranging 2 ~ 8 equal numbers at the main shaft device two ends simultaneously to decide/variable hydraulic motor 7, and this moment, the HM Hydraulic Motor total quantity was 4 ~ 16.The required concrete HM Hydraulic Motor quantity of every gig can be calculated definite to the needs of moment of torsion according to the user.
In conjunction with Fig. 3 and Fig. 4, HM Hydraulic Motor direct-connected planetary gear reducer 6, wherein, epicyclic reduction gear adopts the two-stage transmission, level is parallel-axis type at a high speed, level goes up HM Hydraulic Motor 7 of each root high speed shaft place assembling at a high speed, and many high-speed hydraulic motors are achieved through the type of drive that retarder double reduction rear drive lifting drum rotates; Low speed turbine stage is that NGW is planetary.The big gear wheel C of 2-8 spline shaft gear A external tooth in possesses evenly arranges, and centered by big gear wheel C axis, is the radius engaged transmission with spline shaft gear and big gear wheel width between centers, realizes big gear wheel C rotation of the common driving of multiple spot; The big gear wheel internal tooth is by the cydariform external tooth engagement of unsteady dual gear coupler D and the planetary sun wheel Z of planetary low speed turbine stage.NGW pattern low speed turbine stage is by internal gear pair N, the planetary gear mechanism that secondary W of external meshing tooth and public satellite gear are formed; Common row star-wheel G number is three.The load balancing mechanism that adopts sun wheel to float, sun wheel weight is little, and inertia is little, floats flexibly, and mechanism is simple, makes highly versatile, low speed operating mode in being widely used in easily.
Hydraulic Station is by the HM Hydraulic Motor output balanced hydraulic oil of Closed Hydraulic pipeline 11 to the main shaft device two ends.Oil pipe is linked to be lubricating system 5 with each lubricating point, operating console 12 and lubrication station, and lubrication station is made up of Oil pump electrical machinery device, filter, safety valve, fuel tank and annex; Mainly provide lubricating oil to epicyclic reduction gear and the bearing that needs to lubricate.
In conjunction with Fig. 5, because retarder and HM Hydraulic Motor are equipped with in the main shaft device end, be used for the depth indicator 10 of sign gig container in the position of roadway so and just can not be installed in spindle centerline, thereby pass to depth indicator 10 solutions after by transmission device spindle being offset certain distance.HM Hydraulic Motor drives main shaft and sends actuating signal, and gear 1 is fixed on the main shaft by key, realizes and the same rotating speed of main shaft.Gear 29 is identical with gear one 8 numbers of teeth, keeps same rotational speed that main shaft is rotated by tooth engagement and gear 1 and spreads out of after departing from certain distance.Gear 29 is connected with transmission shaft 15 by key, is arranged on transmission shaft 15 1 ends; Transmission shaft 15 middle parts are provided with bearing seat 18, and bearing seat is fixed on spindle bearing holder 16 sides by screw, are provided with the bearing that supports location transmission shaft 15 in the bearing seat.Transmission shaft 15 other ends arrange sprocket wheel 1, and sprocket wheel one passes to depth indicator 10 by the chain transmission with spindle speed 1:1.Rotatablely moving of hydraulic anti-explosive hoist main shaft, pass on the depth indicator by synchronizer gear group, chain wheel set, large-scale anti-explosion hoisting machine main shaft device two ends are equipped with under the situation of retarder and HM Hydraulic Motor simultaneously, make motion of main shaft can be delivered to depth indicator, drive the depth indicator motion.
Do the time spent, adopt single or multiple two way variable displacement pumps, drive a plurality of constant displacement hydraulic motors or variable hydraulic motor by the Closed Hydraulic pipeline.Adopt how many pumps and motor, determine the requirement of power, speed, quiet tension force according to type and user.Because epicyclic reduction gear is fixed on the hydraulic anti-explosive hoist main shaft device main bearing seat side by fastener, the moment of torsion transmittance process is external tooth → common row star-wheel G → pinion carrier X of cydariform external tooth → sun wheel Z of internal tooth → sun wheel Z of external tooth → dual gear coupler D of internal tooth → dual gear coupler D of external tooth → big gear wheel C of a plurality of HM Hydraulic Motor input torques → a plurality of spline shaft gear A → big gear wheel C, by pinion carrier X internal tooth output torque is delivered on the hydraulic anti-explosive hoist main shaft device main shaft end tooth cover B.
Should illustrate that those skilled in the art within the spirit that does not break away from the invention and principle, any modification of doing, are equal to replacement, improvement etc. on the basis of above preferred embodiment, all should be included within the protection domain of the invention.
