Lifting mechanism with movable and static pulley block

Abstract

The invention discloses a lifting mechanism with a movable and static pulley block. The lifting mechanism comprises two vertical and parallel lifting guide rails, a top beam fixed at the tops of the lifting guide rails, a bearing plate arranged between chutes of the two lifting guide rails vertically in a sliding manner, a hoisting mechanism arranged on the top beam, a movable and static pulley block connected between the top beam and the bearing plate, and a shearing type horizontal pushing mechanism fixed on the bearing plate horizontally. A steel cable winds around the movable and static pulley block; and the two ends of the steel cable are connected with the hoisting mechanism. According to the invention, with the movable and static pulley block, the torque of the crossbar is reduced,the load of the traction servo motor is reduced, and the miniaturizing and energy-saving effects of the motor are realized. The extending amount of the shearing type horizontal pushing mechanism is decided by the rotation angle of a screw rod, so that the control becomes accurate and the centering of the vehicle position is realized. Comb teeth of a comb tooth carrying platform correspond to combtooth gaps of a parking zone carrying platform, so that non-obstacle passing in a vertical direction between the carrying platform is realized and the parking is simplified.

Description

technical field [0001] The invention relates to a lifting mechanism with a dynamic and static pulley block, which is combined with a horizontal pushing device and used for lifting and transporting vehicles in a new three-dimensional garage. Background technique [0002] With the continuous increase of the number of private cars, all kinds of three-dimensional parking garages that can save parking space and improve parking efficiency are gradually being widely used. The three-dimensional parking garage needs to lift the vehicle to be parked to the same height of a specific parking layer by the elevator, and then translate the vehicle to be parked to the parking layer. This step requires a car lifting mechanism to complete. At present, the commonly used vehicle lifting mechanisms mainly include hydraulic scissor type, chain sprocket type and cable winch type. There are some defects and problems when the three lifting mechanisms are applied to the vehicle lifting of the three-...

AI Technical Summary

Problems solved by technology

There are some defects and problems when the three lifting mechanisms are applied to the vehicle lifting of the three-dimensional garage. For example, the lifting height of the hydraulic scissor lifting mechanism is limited, which cannot meet the height requirements of the multi-storey three-dimensional garage; the weight of the chain sprocket lifting mechanism is too high. Large, when the mechanism exceeds a certain height, the transportation efficiency will be greatly reduced, and at the same time, the overall rigidity of the mechanism is high; although the cable winch type lifting device has a simple mechanism, it takes up a lot of space and requires high rigidity for each cable. Not suitable for frequent lifting of heavy objects
