Abstract

The utility model belongs to a tipping device for a mine car. The device takes a circular arc linear motor as the driving mechanism; the circular arc linear motor is fixed on the bracket, and is installed on a bottom beam as a whole. The outer ring of the tipping cage body is tightened with an annular secondary stage; the interstice between the annular secondary stage and the linear motor is 2-4 mm; the interstice can be adjusted by a shim; the tipping cage body is supported to be arranged on a supporting frame comprising a supporting idler and the base of the supporting idler. When is energized, the linear motor drives the annular secondary stage and the cage body to do tipping motion, and thus the mine car in the cage body tips with the cage body to obtain the purpose of self-discharging materials. The utility model has the advantages of simple structure, low failure rate, energy saving, convenience for linkage and automation, etc.

Description

Straight-line motor vehicle tipper

The utility model belongs to a kind of overturning equipment, and specifically a kind of what be used to overturn mine car self-unloading material is the overturning equipment of propulsive effort with linear electric motors.

In mine operation, with the mine car is container, track is in the transport systems of lane of traffic, after mine car transports material arrival unloading position, mine car need be placed and be called the tipper switching mechanism of (claiming upset cage body again), start the tipper rotation, the loose unpacked material in the mine car is discharged in the feed bin or load transfer device below the tipper.At present, the upset of tipper is to drive the rotation of idler pulley device by rotating machine through drop-gear box, relies on the frictional force drives cage body of idler pulley between tipper cage body and the mine car that is contained in the cage body to rotate, to reach the purpose of material in the self-dumping car.This overturning equipment volume is huge, complex structure, fault is more, particularly friction force not enough or at idler pulley surface adhering thing more for a long time, usually cause the cage body not overturn or can not overturn fully.

The purpose of this utility model is, a kind of linear electric motors overturning equipment of direct drive cage body upset of contactless transmission device is provided.It is by electromagnetic force space transmitting torque, and is irrelevant with friction force and binding force, thereby has overcome the above-mentioned shortcoming that drives overturning equipment with rotating machine.

Technical characterictic of the present utility model is that circular arc type linear motor (1) is called elementary being installed on the electric machine support (4) again, and electric machine support is fixed on the bottom girder (8).Upset cage body (2) is placed on four idler pulleies (6), and this idler pulley and idle carrier (7) are formed overall fixed on bottom girder.The outer ring of upset cage body is provided with annular secondary (3), and it is 2～4mm with gap between the linear electric motors (1), can be by changing the size in pad (5) adjusting gap.Mine car (9) places on the interior track (10) of cage body.

Circular arc type linear motor is a kind of known special machines, after feeding 380 volts or 660 volts of three plase alternating currents, just produces a space magnetic field that moves along arc-shaped inner surface.Because the electromagnetic induction effect, the secondary application force that just is subjected to along the arc tangential direction of annular rotates thereby order about upset cage body, reaches the purpose of material in the self-dumping car.Adopt detent mechanism (11), realize that tipping arrangement cuts off the power supply and electromagnetic braking in advance, or mechanical braking, stop on the reference position after can making cage body upset discharging, so that next cycle operation.Vehicle frame (12) is used for fixedly mine car of switching process.

The utility model drives overturning equipment with known rotating machine and compares, and has following advantage: owing to adopted circular arc type linear motor direct drive upset cage body, exempted the transmission conversion links of a series of complexity in the prior art; Owing to adopt spatial movement magnetic field to produce overturning couple, exempted the adhesion of skidding that the frictionally upset occurs in the prior art, cause the phenomenon that can not overturn; Because the idler pulley mechanism that adopts antifriction-bearing box to form has reduced friction drag, improved the alerting ability of upset.In sum, the utility model simplifies the structure, and has reduced volume, has improved the equipment service efficiency, has saved electric energy, and provides condition for interlockization and the automation with go-cart equipment.Simultaneously, it is little that the utility model takes up an area of the space, installs easily, is convenient to maintenance, is applicable to the requirement of various dissimilar mine cars.

Accompanying drawing 1 and accompanying drawing 2 are respectively the front view of linear electric motors overturning equipment and A-A to surveying view (scheme drawing).

Among the figure, 1 is circular arc type linear motor, and 2 are upset cage body, and 3 is that annular is secondary, and 4 is electric machine support, and 5 is pad, and 6 is idler pulley, and 7 is idle carrier, and 8 is bottom girder, and 9 is mine car, and 10 is track, and 11 is detent mechanism, and 12 is vehicle frame.

Accompanying drawing has been described an embodiment of the present utility model.

Circular arc type linear motor (1) is fixed by bolts on the electric machine support (4), and electric machine support (4) is fixed on the bottom girder (8).Banded annular secondary (3) is fastened on the outer ring of upset cage body (2), and upset cage body (2) is placed on the idler pulley (6), and idler pulley (6) is assemblied on the idle carrier (7), and idle carrier (7) is used bolt with bottom girder (8).By the thickness of conversion pad (5), regulate the gap between linear electric motors (1) and the annular secondary (3).Be fixed on the location after detent mechanism (11) on the carriage (4) is used for cage body (2) upset, mine car (9) places on the track (10) in the cage body (2), and track (10) is fixed on the vehicle frame (12).

The utility model is to have the secondary cage body of annular with the circular arc type linear motor direct drive to make flip-flop movement, reaches the purpose of discharging thereby the mine car that places in the cage body is overturn together, and it is applicable to the tipping arrangement of various mine cars and similar containers.
