Abstract

The invention relates to an electric lifting mechanism for a self discharging truck with a self locking function, which comprises a car frame, a speed reducer, a screw rod, a sliding block, a car hopper, a connecting rod and a motor; the screw rod is connected with the sliding block through a screw pair; the sliding block is connected with the car hopper through a third revolute pair; the other end of the car hopper is connected with the connecting rod through a second revolute pair; the other end of the connecting rod is connected with the car frame through a first revolute pair; and the screw rod is driven by the motor through the speed reducer. The electric lifting mechanism for the self discharging truck with the self locking function adopts a way of motor drive and connecting rod transmission, can effectively solve the defects that the traditional hydraulic type self discharging hydraulic system has high requirements on processing and assembly of parts, short service life, oil leakage, high repair and maintenance cost and the like, and has good dynamic and static mechanical properties and large working space.

Description

A kind of self-unloading Vehicular electric lifting mechanism with auto-lock function
Technical field
The present invention relates to the engineering dump truck field, particularly a kind of self-unloading Vehicular electric lifting mechanism with auto-lock function.
Background technology
Dumping car is a kind of through installing a cover lifting mechanism on the chassis additional, utilizes lifting mechanism with compartment tilt certain angle unloading and the special-use vehicle that relies on the compartment deadweight that it is resetted.Existing dumping car is hydraulic driven; Have advantages such as simple in structure, that hoisting force is big; But its hydraulic efficiency pressure system exists hydraulic pressure component process and assemble and requires shortcomings such as height, maintenance difficulty, manufacturing cost height; The hydraulic oil temperature influence is big, net effciency is low, and the hydraulic oil of leakage can cause environmental pollution, and this problem has seriously restricted the application and the popularization of dumping car.And the lifting mechanism of the dumping car fluid pressure type of this quasi-tradition is because of the restriction of himself structure, problem such as it is bad also to exist mechanism's mechanical property, and working space is less.
Summary of the invention
The object of the present invention is to provide a kind of self-unloading Vehicular electric lifting mechanism with auto-lock function; Adopt motor-driven; The mode of connecting rod transmission; Can effectively solve conventional hydraulic formula dumping car hydraulic efficiency pressure system parts process and assemble and require high, life-span shortcomings such as length, leakage of oil, maintaining cost height not, the dynamic and static mechanical property of mechanism is good, and working space is big.
The present invention achieves the above object through following technical scheme:
A kind of self-unloading Vehicular electric lifting mechanism with auto-lock function comprises vehicle frame, retarder, leading screw, slide block, wagon box, connecting rod and motor.
Said leading screw is connected with slide block through screw pair, and slide block is connected with wagon box through the 3rd revolute pair, and the wagon box other end is connected with connecting rod through second revolute pair, and the connecting rod other end connects to ground through first revolute pair, and said leading screw is driven through retarder by motor.
Outstanding advantage of the present invention is:
1, adopts the motor-driven lifting mechanism, avoided hydraulic efficiency pressure system leakage of oil, Hydraulic Elements manufacturing requirement is high, upkeep cost is high shortcoming;
2, the overturning pivot of wagon box is positioned at the position near the wagon box mid point, has improved the stressing conditions of tipper lifting mechanism.
3, the driving device of mechanism adopts the mode of lead screw transmission, has auto-lock function, can guarantee wagon box holding position and attitude under the situation of unpowered input.
Description of drawings
Fig. 1 is a kind of structural representation with self-unloading Vehicular electric lifting mechanism of auto-lock function according to the invention.
Fig. 2 is a kind of first working state schematic representation with self-unloading Vehicular electric lifting mechanism of auto-lock function according to the invention.
Fig. 3 is a kind of second working state schematic representation with self-unloading Vehicular electric lifting mechanism of auto-lock function according to the invention.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment technical scheme of the present invention is described further.
Map 1, said self-unloading Vehicular electric lifting mechanism with auto-lock function comprises vehicle frame 1, retarder 6, leading screw 5, slide block 4, wagon box 3, connecting rod 2 and motor 7.Said leading screw 5 is connected with slide block 4 through screw pair 11, and slide block 4 is connected with wagon box 3 through the 3rd revolute pair 10, and wagon box 3 other ends are connected with connecting rod 2 through second revolute pair 9, and connecting rod 2 other ends are connected with vehicle frame 1 through first revolute pair 8.Said leading screw 5 is driven through retarder 6 by motor 7; Leading screw 5 drives slide block 4 through screw pair 11 and moves; Slide block 4 drives wagon box 3 through the 3rd revolute pair 10 and rotates around the 3rd revolute pair 10; Wagon box 3 rotates around second revolute pair 9 through second revolute pair, 9 drivening rods 2, and wagon box 3 rotates the dumping car unloading task of accomplishing around the 3rd revolute pair 10.
Map 2, the dumping car wagon box was in the initial position in the work when slide block 4 moved to Far Left.
Map 3, the dumping car wagon box was in the unloading position in the work when slide block 4 moved to rightmost.

Claims (1)

1. the self-unloading Vehicular electric lifting mechanism with auto-lock function comprises vehicle frame, retarder, leading screw, slide block, wagon box, connecting rod and motor, it is characterized in that:
Said leading screw is connected with slide block through screw pair, and slide block is connected with wagon box through the 3rd revolute pair, and the wagon box other end is connected with connecting rod through second revolute pair, and the connecting rod other end connects to ground through first revolute pair,
Said leading screw is driven through retarder by motor.
