Abstract

The utility model discloses an automatic unloading unit which comprises a bottom sloping plate on the left side, a bottom sloping plate on the right side, a middle sloping plate, a beam and a power unit, wherein the bottom sloping plates are articulated with the middle sloping plate, the upper end of the middle sloping plate is articulated with the beam, and a position of the bottom surface which is 20 cm to 40 cm away from the outer end to the inside of each bottom sloping plate is articulated with a carriage chassis; the power unit drives the beam to move up and down, the articulated point of each bottom sloping plate and the carriage chassis is retracted to the inside by 20 cm to 40 cm; a resistance arm is shortened, and the needed lifting force is also reduced. The utility model has the advantages of simple structure and simple and convenient operation, and the unloaded materials in different chambers can be easily controlled and can be unloaded separately in different places. When the automatic unloading unit is used in the process of automatic unloading, the stability is strong and the security is high; the axle weight distribution is reasonable, and the manufacture of a self-unloading wagon is not limited; and the self-weight can be lightened, the effective loading mass and the effective transportation efficiency are improved, the fuel consumption is less, and thus, the transportation cost can be reduced.

Description

Automatic unloading unit

Technical field

The utility model relates to the automatic unloading unit that a kind of dumping car is used.

Background technology

Existing dumping car only uses in static state, can only hypsokinesis or the one-sided material that dumps; The material that is unloaded is in the way, buries tire, end back door and damages back door hinge; During self-unloading, left and right trailing wheel will be in same plane, in order to avoid overturn; And lift height is higher, and center of gravity is improved has increased danger; And the body lifting angle is bigger, and the hydraulic ram stroke is long, and the power of lifting mechanism requires big; From heavy, energy resource consumption and traffic cost are high.

For this reason, the patent No. is that the utility model patent of ZL96232418.3 discloses a kind of technical scheme, has the automatic unloading unit of a kind of midsplit type in this technical scheme, the automatic unloading unit of this midsplit type is by a left side, the slanted floor plate and the intermediate, inclined plate of right both sides, crossbeam, engine installation constitutes, wherein slanted floor plate and intermediate, inclined plate are hinged, the upper end and the crossbeam of intermediate, inclined plate are hinged, the avris of the lower end of slanted floor plate and loading space base plate is hinged, engine installation drives and can move up and down by crossbeam, after engine installation is with crossbeam jack-up or pull-up, crossbeam drives a hinged left side, the slanted floor plate of right both sides and intermediate, inclined plate rise and are ^ shape, and bulk freight is detachable both sides to lorry in the loading space.

The shortcoming that this technical scheme exists is, the avris of the lower extreme point of slanted floor plate and loading space base plate is hinged, during unloading, engine installation begins to want the weight of the whole goods of jack-up, so, needs the more high-performance engine installation of configuration or two hydraulic efficiency gear, cause cost to improve and dumping car energy resource consumption and traffic cost raising, moreover lift height is higher, and engine installation forms and makes the center of gravity raising increase danger.

Summary of the invention

The purpose of this utility model is in order to solve the shortcoming that the ZL96232418.3 utility model patent exists, and the automatic unloading unit that provides a kind of dumping car to use, this device does not need the more high-performance engine installation of configuration or disposes engine installation less, the lift height of this automatic unloading unit is relatively low, center of gravity is reduced, and then improved safety, reduced manufacturing cost; Use the dumping car energy resource consumption and the traffic cost of this automatic unloading unit low.

The utility model is by a left side, the slanted floor plate and the intermediate, inclined plate of right both sides, crossbeam, engine installation constitutes, wherein slanted floor plate and intermediate, inclined plate are hinged, the upper end and the crossbeam of intermediate, inclined plate are hinged, the bottom surface and the railway carriage underframe of slanted floor plate inside segment distance from the outer end are hinged, engine installation drive crossbeam can more than, move down, after engine installation is with crossbeam jack-up or pull-up, crossbeam drives a hinged left side, the slanted floor plate of right both sides and intermediate, inclined plate rise and are ^ shape, and the bulk freight in the container on it is detachable both sides to lorry.

The beneficial effects of the utility model are:

1, hinge-point indentation to the inside one segment distance of slanted floor plate and railway carriage underframe, resistance arm shortens, and under resistance unmodified situation, hoisting force is directly proportional, and required hoisting force also reduces, and concrete analysis is as shown in Figure 1; Get according to plane statically determimate structure equation of equilibrium:

G * L1=F * L2; Wherein, G is the weight of goods; F is a hoisting force;

F＝G×L1/L2

If L1=40cm; L2=100cm

When hinge-point moves inward 10cm

F＝G×1/3

When hinge-point moves inward 20cm

F＝G×1/4

When hinge-point moves inward 30cm

F＝G×1/7

Therefore, an elevating ram can be only adopted in every storehouse of dumping car, can finish the work of unloading.

2, hinge-point indentation to the inside one segment distance of slanted floor plate bottom surface and railway carriage underframe, resistance arm shortens, and the lift height that needs is reduced.

3, use dumping car of the present utility model, the self-unloading material is not kept off a car, is out of the way, is not buried (bumping) tire and destroy the back door to the vehicle both sides under steam; Lift height is low, laborsaving, save time, save space; The railway carriage volume is big, the degree of utilization height; Simple in structure, easy and simple to handle, easily material is dumped in branch storehouse control, but and the strange land branch unload; Vehicle stability is strong in the operation, and is safe; Distribution of axle load is reasonable, and dumping car is made unrestricted; The deadweight light-weight design, it is few to improve efficient loading quality and conveying efficiency and oil consumption, has reduced traffic cost.

The specific embodiment

See also Fig. 2, shown in Figure 3, scheme drawing for the utility model embodiment, this embodiment is by a left side, the slanted floor plate 1 and the intermediate, inclined plate 2 of right both sides, crossbeam 3 and elevating ram 4 constitute, slanted floor plate 1 wherein is hinged with intermediate, inclined plate 2, the upper end of intermediate, inclined plate 2 and crossbeam 3 are hinged, the bottom surface of slanted floor plate 1 and railway carriage underframe are hinged, this hinge-point 5 is 20cm～40cm apart from the distance of the outer end 6 of slanted floor plate 1, elevating ram 4 drives crossbeam 3 and moves up and down, after elevating ram 4 is with crossbeam 3 jack-up, crossbeam 3 drives a hinged left side, the slanted floor plate 1 of right both sides and intermediate, inclined plate 2 rise and are ^ shape, and the bulk freight in the container on it is detachable both sides to lorry.

Moreover engine installation can also be the device that upwards draws except using elevating ram 4.
