Detailed Description

The utility model is described in further detail below with reference to the figures and specific examples. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

The full-automatic vertical lifting machine for picking and placing the core car is a full-automatic vertical and horizontal transfer device of the core car, can transfer a full-load core car from a high station (a car loading point) to a low station (a car placing point), can pick a no-load core car from a middle station (a car picking point), and returns to the high station to convey the no-load core car to a car discharging point.

As shown in fig. 1 to 3, the vertical lift for a full-automatic core picking and placing vehicle according to the embodiment of the present invention includes a vertically arranged frame 5, a rail 4 arranged on the frame along an axial direction of the frame, and a lifting frame 4 driven by a driving mechanism to lift in the rail, wherein a telescopic fork 7 is mounted on the lifting frame 4, and the telescopic fork is used for carrying a core vehicle to realize the entry and exit of the core vehicle.

As an alternative embodiment, the lifting frame is a frame body with a rectangular body-shaped structure, the two rails are oppositely arranged, and the lifting frame is arranged between the two rails and is contacted with the rails through at least one group of guide wheels at each side.

The group of guide wheels 9 includes two side guide wheels 92 symmetrical with the axis of the rail and a main guide wheel 91 contacting with the rail, and the axis direction of the main guide wheel is perpendicular to the axis direction of the two side guide wheels.

And two groups of guide wheels are arranged on each side face of the lifting frame matched with the rail and are arranged at intervals up and down.

The lifting frame 1 is driven by a steel wire rope 8, a winding drum 3, a chain wheel 2 and a lifting motor 1, is lifted in a track according to a program instruction, and can stop at a specified position and take and place a core car through a telescopic fork 7.
