Embodiment Construction

[0021] The present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0022] figure 1 Shown is a schematic diagram of one embodiment of a dual-motor drive device and control method for parking equipment of the present invention.

[0023] among them, figure 1 The dashed box below is a schematic diagram of the device in this embodiment. As can be seen in the figure, the No. 1 motor 7-1 on the left is fixedly installed above the left column, the No. 1 motor 7-1 drives the No. 1 worm gear reducer 6-1, and the motor output shaft is tightly connected to the reducer Worm, reduction box and worm wheel are tightly connected to No. 1 screw 9-1; No. 1 nut seat 10-1 is set on No. 1 screw 9-1, cannot rotate, can only rise or fall; No. 1 nut seat 10- Below 1 is the vehicle board 12, between which is hauled by two steel ropes (one of the traction rope 11-1a and the second traction rope 11-1b); and the motor 7 The output shaft of -1 i...

Abstract

The invention provides a double-motor driving device of a parking device and a control method thereof. The double-motor driving device of the parking device and the control method thereof solve a deficiency of safety hazard which is caused by a current parking device adopting a single motor to drive a chain or a steel wire to perform cycle traction and installation size limitation of single motor which drives two sets of screw-nut mechanisms. The double-motor driving device is constituted by two sets of power driving mechanisms consisting two sets of motors having identical parameters and a reduction gearbox and respectively drives two sets of screw and screw units; two nut seats performs traction on two sides of a vehicle-loading plate to achieve elevation driving through pulling by the steel wire or traction through the screws; the driving device control method adopts two frequency converters with identical parameters and matched measures to realize synchronous control on two three-phase asynchronous machines and provides multiple schemes to choose.

Description

Technical field [0001] The invention relates to the technical field of mechanical parking equipment, and more specifically, to a vertical lifting drive device and a control method for an upper deck of a two-story parking device in which two vertical columns clamp the upper deck to vertically lift. Background technique [0002] With the increase in car ownership, the problem of insufficient parking lots has become increasingly obvious. Mechanical parking equipment has been widely used, and the two-tier parking equipment has a larger market share. In the two-story parking equipment, there are two vertical columns (including symmetrical layout and asymmetrical layout) in the middle to clamp the upper platform to vertically lift. The structure of the existing equipment uses a single motor to drive a chain or a wire rope loop traction method. This method causes structural differences in the traction support drive mechanism on both sides of the car board (direct drive on one side and i...
