Abstract
A driving device of a maintenance trolley of a mine crushing station belongs to the open-pit mine crushing station maintenance equipment, which resolves problems that the maintenance trolley is driven by the existing electric reels so that steel wire ropes are difficult to connect and problems that the maintenance trolley is driven by gears and racks and the racks are long and easy to deform. A bearing support is connected with a drive shaft through a large diameter roller bearing and small diameter roller bearing. The large diameter roller bearing and the small diameter roller bearing are arranged at two ends of the bearing support. The bearing support is fixed on a maintenance trolley body, a large diameter end of the drive shaft is connected with trolley wheels, the other end of the drive shaft is connected with a three-in-one speed reducer, the left end face of the bearing support is fixed with a left end cover, and the bearing support right end face is fixed with a right end cover. A labyrinth ring is arranged between the wheels and an inner ring of the large diameter roller bearing, a sealing felt ring is installed between the right end cover and the drive shaft, and a checking ring is arranged between an inner ring of the small diameter roller bearing and the sealing felt ring. The maintenance trolley applied in the open-pit mine crushing station has the advantages of being simple in structure, reasonable in design, low in maintenance time and low in maintenance cost.
Description
Technical field
The utility model relates to surface mine Crushing Station repair apparatus, particularly the maintenance dolly of Crushing Station.
Background technology
At present, the maintenance dolly of domestic mine Crushing Station, employing be that electric reel drives, be to realize traction to the maintenance dolly by steel rope and fixed pulley.The shortcoming of this type of drive is: before each dolly work, steel rope need be crossed over more than 10 meter long Crushing Station surge bunker, be connected with electric reel, steel rope connects very difficult.After dolly is finished the work, need again steel rope to be dismantled, waste time and energy.
The mine Crushing Station maintenance dolly of Germany Krupp, employing be type of drive by three-in-one reductor driven gear rack mechanism.The shortcoming of this type of drive is: because of nearly 15 meters long of dolly forced stroke, so need to adopt 15 meters long tooth bars, not only investment big, take up room manyly, and the use middle rack can be out of shape, and causes the rack-and-gear engagement bad, and then equipment breakdown takes place.
Summary of the invention
The purpose of this utility model is intended to overcome the shortcoming of prior art, and the actuating device of a kind of mine Crushing Station maintenance dolly is provided, and solves existing electric reel type of drive steel rope and connects difficulty; The problem that rack-and-gear type of drive tooth bar is long, equipment breakdown more greatly, easily takes place in investment.
The utility model is achieved through the following technical solutions.
The actuating device of a kind of mine Crushing Station maintenance dolly, it is characterized in that: described actuating device comprises: bearing seat, the major diameter coro bearng, the minor diameter coro bearng, axle drive shaft, wheel, keep in repair little car body, described bearing seat is by being installed in the described major diameter coro bearng at two ends, the minor diameter coro bearng is connected with described axle drive shaft, described bearing seat is fixed on the little car body of maintenance, the larger diameter end of described axle drive shaft is connected with described wheel, the other end of described axle drive shaft is connected with three-in-one reductor, the left side of described bearing seat is by the bolt left end cap, the right side of described bearing seat is by the bolt right end cap, be provided with labyrinth between the inner ring of described wheel and described major diameter coro bearng, between described right end cap and described axle drive shaft the sealing felt collar is housed, between the inner ring of described minor diameter coro bearng and described sealing felt collar back-up ring is housed.
Be positioned at the bearing top above the described bearing seat lubricating cup is housed.Lifting eye bolt are equipped with in described bearing seat top.
The utility model compared with prior art, because the utility model is the wheel by three-in-one reductor direct drive maintenance dolly, drive the maintenance dolly and on Crushing Station steel structure track, move, overcome the maintenance dolly and driven, the shortcoming of bringing the mounting or dismounting steel rope to waste time and energy by cable drum; Solved the maintenance dolly and driven, brought tooth bar length, yielding problem by rack-and-gear.The utility model is not only simple in structure, and is reasonable in design, and can guarantee to keep in repair dolly and enter mode of operation at any time, thereby shortened the overhaul of the equipments time.The suffered diametral load of bearing seat is born by the bearing that varies in size respectively, has improved the load-carrying capacity of bearing, has prolonged the service life of bearing.Can shorten and reduce equipment downtime and service expenditure greatly.
