A lower table forward rotation device and control method

Abstract

The invention provides a lower platen forward-moving and rotating device. The lower platen forward-moving and rotating device is simple in structure and comprises a motor reducer, a rotating-side guiding rail, a straight-moving-side guiding rail, an arc-shaped guiding rail, a rotating-side rotating shaft, a rotating-side driving wheel, a straight-moving-side rotating shaft, a straight-moving-sidedriving wheel, bearing seats, a sprocket transmission unit, an electromagnetic clutch, a rotating guiding unit, universal guiding wheels and a position detection unit. A lower platen is accurately andeffectively guided during straight-moving displacement through an inner groove double-guiding-rail structure and the arc-shaped guiding rail; during straight-moving displacement and rotating displacement of the lower platen, the rotating-side driving wheel makes contact with working planes of the rotating-side guiding rail and the arc-shaped guiding rail, the straight-moving-side driving wheel makes contact with working planes of the straight-moving-side guiding rail and a straight-moving short guiding rail, and the driving wheels do not make contact with the ground, so that abrasion to the ground is avoided; and moreover, the guiding rails are each of a steel structure, the bearing capacity of the working planes is large, thus the boundary dimensions of the driving wheels can be greatlydecreased, equipment overall layout is facilitated, and the equipment overall durability is greatly improved.

Description

technical field [0001] The present invention relates to the field of mechanical parking equipment, in particular to a two-layer parking equipment with the lower platform (that is, the platform on the ground floor) moving forward and rotating. This type of parking equipment requires the lower platform to stand normally at the parking space on the ground floor and move to the lane, and Transitions between avoidance states parallel to the centerline of the lane. Background technique [0002] With the increase of car ownership, the problem of insufficient parking space is becoming more and more obvious, and mechanical parking equipment has been widely used. In order to solve the deficiencies of the traditional two-story lift-and-slide type and simple lift-type parking equipment, the type of two-story parking equipment with the lower plate moving forward and rotating has appeared in China in the past ten years. At present, in this type of parking equipment, the structure of the ...

AI Technical Summary

Problems solved by technology

At present, in this type of parking equipment, the structure of the lower table forward rotation device is relatively complicated, installation and maintenance are relatively difficult, and it is easy to be damaged during use. These shortcomings have affected the popularization and use to a certain extent.

[0003] Published on May 31, 2017, the application number is 201710032993.4, and the invention application titled "a lower table forward rotation device" discloses a technical solution for a lower table forward rotation device with a simple structure. , a power roller unit, a linear guide unit and a rotary guide unit. Through the simple cooperation control of the electromagnetic clutch device and the motor deceleration device, the lower platform can be normally placed and moved to the lane at the parking space on the ground floor and parallel to the lane. The transition between avoidance states of the centerline is obviously different from the existing technology and has significant advantages, but there are still deficiencies in the two aspects of guiding accuracy and bearing capacity

Specifically: the single-sided guide rail and guide wheel positioning structure are difficult to meet the accuracy of the linear movement of the lower table; the total mass of the lower table is supported by the rollers touching the ground. Due to the low bearing capacity of the ground, the size of the rollers is relatively large, which is not conducive to the overall layout; The rollers form severe friction with the ground, which can easily cause surface damage, and the durability of related parts is relatively low
