Electric lifting mechanism for self discharging truck with self locking function

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

technical field [0001] The invention relates to the field of engineering dump trucks, in particular to an electric lifting mechanism for dump trucks with a self-locking function. Background technique [0002] A dump truck is a special vehicle that installs a lifting mechanism on the chassis, uses the lifting mechanism to tilt the compartment at a certain angle to unload, and relies on the self-weight of the compartment to reset it. The existing dump trucks are all hydraulic transmission type, which has the advantages of simple structure and large lifting force, but its hydraulic system has the disadvantages of high processing and assembly requirements for hydraulic components, difficult maintenance, high manufacturing cost, etc., and the hydraulic oil is greatly affected by temperature. , The overall efficiency is low, and the leaked hydraulic oil will cause environmental pollution, which seriously restricts the application and promotion of dump trucks. Moreover, due to the...
