It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, a buffer control optimization method for a car dumper buffalo pushing system includes the following steps:
1) optimally removing empty car and cattle driving devices in each set of driving mechanisms of an empty-load cattle discharging and heavy-load cattle returning of a car dumper and cattle pushing system, reserving the driving devices of the heavy-load cattle returning, and changing the original motor of the heavy-load cattle returning into a reversible running motor; replacing a first shaft of the speed reducer, installing a motor on the first shaft of the speed reducer, and transmitting power from the first shaft to the open gear driving drum device through three-level transmission of the speed reducer through a coupler;
the motor for returning the original heavy load to the cattle is changed into a reversible operation motor, and the reversible operation motor is as follows:
and adding a frequency converter, and rewiring a motor circuit according to a design to enable the motor to run reversibly.
The original one set of driving mechanism for unloading and reloading the empty cattle is changed into a single set of driving mechanism, namely, the empty-car iron cattle driving device is optimized to be removed and comprises a small motor, a frequency-sensitive resistor, a brake and the like. In order to ensure the function of discharging empty cows, the motor of the original heavy-load returning cows can only work in a positive rotation mode and is changed into a reversible operation mode, and one motor can drive a discharging bull and a returning bull simultaneously. The improved transmission mechanism has the advantages that the driving unit is reduced, the number of the transmission members connected in series is obviously reduced, the transmission chain is shortened, on one hand, the mechanism efficiency is improved, the transmission efficiency is higher, on the other hand, the excessive mutual impact vibration of the transmission members is also slowed down, the structure is compact, the transmission strength is enhanced, and the occupied space is also reduced.

The transmission mode of the wet friction clutch system is complex, and the transmission mode is complex, and the judgment is not good, so that the difficulty is brought to production and maintenance, the labor intensity of maintenance workers is reduced after deletion, the production efficiency is improved, and the equipment fault is reduced.
With the elimination of the wet friction clutch system, the hydraulic system of the transmission also loses its function. In order to improve the bearing lubrication of the speed reducer, the bearing lubrication of the speed reducer is improved, in order to save spare part cost, an oil pump of an original hydraulic system is used for supplying oil to the bearing of the speed reducer and lubricating the bearing, and the effect of the bearing is ensured, and the oil pump is arranged at the shaft end of the speed reducer, as shown in figure 2.
3) The buffer is additionally arranged at the corresponding part of the combination of the iron cattle and the train, as shown in figure 3, the buffer is arranged in an iron cattle hook, a buffer body 1 comprises a buffer spring 2, a buffer screw rod 3, a buffer cylinder 5, a gland 4 and a spring press buckle 6, the buffer spring is arranged in a spring cylinder, the buffer spring is sleeved on the buffer screw rod of the receiving train, the buffer screw rod is connected with the combination part of the iron cattle and the train hook, and the buffer screw rod is a telescopic screw rod;
when the iron cattle is connected, the spring pressing buckle springs open, the buffer screw rod retracts into the spring barrel under the impact of spring pressure and external force, the spring pressing buckle restores and locks the spring in the barrel, and the unhooking on the train automatically moves downwards and the iron cattle is automatically hooked;
when the iron bulls are separated from the train, under the action of spring tension and impact of the iron bulls, the spring pressing buckle bounces the buffering screw rod to extend out of the spring cylinder and upwards push the unhooking connection on the train, and the iron bulls and the train hook are separated and unhooked;
in order to avoid the breakage caused by the impact fatigue of the steel wire rope due to the overlarge impact of the train and the iron cattle when the iron cattle receive the train, the buffer reduces the impact of the iron cattle and the train wagon, thereby reducing the impact on the iron cattle steel wire rope.
4) And (5) running in a trial mode, and finishing optimization after the normal operation is confirmed.
Through the optimization and transformation, the running condition of the heavy and light iron cattle trolley system of the tipper is greatly improved, and since the tipper is produced after being updated in this year, sudden equipment faults do not occur together under the conditions that the production capacity is increased and the hourly operation capacity is improved by 50 percent, the scheduled maintenance is carried out for 3 times, the time is 12 hours, the equipment reliability is high, the faults are low, the potential safety hazard that personnel are easily injured due to the fact that the heavy and light cattle steel ropes are pulled out, and the safety production of workers is guaranteed. And accidents of breaking the shaft and beating teeth of the speed reducer and pulling and overturning the motor are also avoided. The production benefit is improved, the station pressing time of the wagon is shortened, and the lease fees of the wagon are reduced. The labor intensity of operators and maintenance workers is reduced. The speed reducer fault and the personal injury accident caused by the breakage of the steel wire rope due to large mechanical impact are avoided, and the improvement of safety cost is facilitated. The production efficiency is also improved, and the operation benefit can meet the requirements of design and production.
It will be understood that modifications and variations can be made by persons skilled in the art in light of the above teachings and all such modifications and variations are intended to be included within the scope of the invention as defined in the appended claims.
