Speed measuring device in the utility model, degree of depth sending set are existing installation.Roll device in the utility model is with the steel rope layer to layer transition device on the spiral fluted reel to apply for patent with being arranged on the roll device, the patent No. is respectively 200720029808.8 and 200720029692.8, does not repeat them here.
The utility model transmission principle is: under the non-braking mode of service brake, the electrical motor energising is rotated, output torque, give the reductor input shaft by elastic coupling with transmission of torque, deceleration by reductor, torque is exported by speed reducer output shaft, key is connected with dental type coupling on the speed reducer output shaft, the other end of dental type coupling is installed on the pinion shaft in the miniature gears assembling, and by the coupler connecting key, pinion shaft, the miniature gears connecting key is given miniature gears with transmission of torque, big gear wheel engagement on miniature gears and the roll device, and torque passed through big gear wheel, steel bushing, tie bolt passes to reel, and reel rotates winding (or unclasping) steel rope output torque and finishes lifting (or transferring) work.In whole transmission process, reductor plays rev down and increases torque, and miniature gears and big gear wheel engaged transmission are once more rev downs and increase torque that final reel torque reaches more than the 638kN.m, the steel rope biggest quiet tension reaches 500kN, and the linear velocity of steel rope is 9m/min.
When needing stopping brake at work, the electrical motor outage, service brake outage is simultaneously braked the brake wheel on the elastic coupling, and lock torque passed to reel by reductor, dental type coupling, coupler connecting key, pinion shaft, miniature gears connecting key, miniature gears, big gear wheel, steel bushing, tie bolt, make its ramp to stop.
When emergency situation being arranged at work or have safety hazard to take place, Hydraulic Station outage release, sure brake is braked the brake wheel on the roll device, and lock torque is passed to reel by steel bushing, tie bolt, makes its sudden stop.When the sure brake glancing impact, the electrical motor outage is not in running, and service brake is power-off brake also, assists sure brake to do emergency braking.
When gig at a slow speed when heavy duty is transferred hypervelocity and is reached certain numerical value, speed measuring device can send signal, prompting operation person, the operator can carry out the electric driving force braking deceleration to electrical motor, makes speed be returned to operating needs.In addition, dynamic brake can be provided with deceleration point at stop position slows down, and can assist the service brake vehicle positioning stop more accurately.
The utility model can rise to the great object pulsation-free of 500kN on the mine or transfer under the mine, has avoided the fractionation transportation of great object.Processed plug helix on the reel, disposed steel rope layer to layer transition device, reel can well be arranged lay winding wire ropes, and the interlayer that prevents steel rope under the heavy lift operating mode is reined in the rope extruding.The reel two ends partly are inserted into respectively in big gear wheel, the brake wheel, the reel both ends of the surface directly are connected with big gear wheel, brake wheel mid-plane former, by means of the rigidity of reel, under the heavy lift operating mode, have reduced the distortion of big gear wheel, brake wheel.Because the reel moment of torsion acts directly on big gear wheel, the brake wheel mid-plane former, make stressed symmetrical equilibrium more in big gear wheel, the brake wheel work again.
Gig is equipped with sure brake, service brake, electric driving force braking at a slow speed, and their collaborative works are used respectively according to various work condition states again, has realized big lock torque combination utilization:
1), sure brake is the hydraulic failure plate disc brake, directly the brake drum device plays the safety guard-safeguard effect, only just participates in braking when safety hazard takes place or during the shutdown off working state, its lock torque is not less than 2 * 638=1276kN.m.
2), service brake is power hydraulic pressure tile fragment drg, the brake wheel on the braking elastic coupling mainly cooperates the start and stop of main motor, doing the location of stopping and using, it is not less than 2 * 638=1276kN.m to reel equivalent conversion lock torque.Take place as safety hazard, during the sure brake power-off brake, service brake also can be assisted the sure brake power-off brake.
3), electric driving force braking is mainly used in gig heavy duty at a slow speed and transfers hypervelocity, in the work, when overspeed signal sends and reach certain numerical value, adds dynamic brake, makes speed be returned to operating needs.In addition, dynamic brake can be provided with deceleration point at stop position slows down, and can assist the service brake vehicle positioning stop more accurately.
