Four-post four-lifting-point chain type lifter for car side wall

Abstract

The invention discloses a four-post four-lifting-point chain type lifter for a car side wall. The four-post four-lifting-point chain type lifter comprises an auxiliary beam, a fixed rack, a drive device, a movable framework, a counterweight block and four guide posts, wherein the fixed rack is arranged on the auxiliary beam. The four-post four-lifting-point chain type lifter is characterized in that four corners of the movable framework are symmetrically provided with four movable framework guide wheels; upper and lower ends of the counterweight block are symmetrically provided with counterweight block guide wheels; the drive device comprises a motor speed reducer, a shaft coupler, a drive chain wheel transmission shaft, a duplex chain wheel I, a driven chain wheel transmission shaft, a duplex chain wheel II, two long transmission chains, two driven chain wheels, two short transmission chains and a plurality of bearing bases; the two long transmission chains and the two short transmission chains are open type chains; and the motor speed reducer is arranged on the auxiliary beam. The four-post four-lifting-point chain type lifter is simple in structure, uniform in stress, stable in operation, great in hoisting weight, high in guide precision, safe and reliable, and long in service life.

Description

technical field [0001] The invention relates to a conveying machine, in particular to a four-column and four-suspension-point chain lift on the side of an automobile. Background technique [0002] On the conveying line of the side wall of the car (that is, the workpiece), it is often necessary to lift the side wall of the car to meet the process requirements. The existing lift structure uses four ground columns as guides, and two cranes are installed in the middle of the movable frame. point, two single sprockets are used, and a chain is installed on each single sprocket to lift the lifting point in the middle of the movable frame. The elevator with this structure has only two lifting points, so it is not easy to lift it. Stable, easy to shake, unsafe, and the lifting weight is also small, and it may be stuck between the ground column and the guide wheel of the movable frame due to the installation error of the four ground columns or due to partial load, which is serious , ...
