Embodiment Construction

[0016] Embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings:

[0017] The composition of this walking trolley is divided into a walking part and an access trolley part. The four supporting wheels 2 evenly distributed at the four corners of the bottom of the trolley main body I play a supporting and guiding role, and the driving wheel 10 elastically connected with the trolley main body I1 is driven by the motor. To make the trolley move, the elastic connection can ensure that the driving wheel is always in contact with the ground, and can make the trolley move bidirectionally.

[0018] One side of the middle part of the trolley main body I1 is provided with a guide rail 12 along the traveling direction of the trolley, and the middle part of the bottom plate of the trolley main body II9 is ​​provided with a chute matched with the guide rail of the trolley main body I1. When the walking trolley is working, the tro...

Abstract

The invention relates to a V-shaped and clamp-typed hydraulic walking car, pertaining to the vehicle parking and taking field in stereo garage. The invention comprises a walking part and a parking and taking part. The walking part is consists of four support wheels (2), a group of flexibly connected drive wheels (10) which provide direct drive to the walking car and a motor connected with the drive wheels; the parking and taking part comprises a car body I (1) and a car body II(9) which slides in the car walking direction on a guide rail (12) on the car body I(1). The car body I (1) and the car body II(9) are divided into an upper layer and a lower layer, wherein the lower layer is evenly provided with four V-shaped clamps (3). One side of the clamps (3) is the end for clamping vehicle wheels and the middle part of the other side is provided with a slide way; the end part of the clamps (3) is provided with a trolley (6). The two ends of a hydraulic cylinder (7) are articulated with two transverse pull rods (8) which are vertical to the hydraulic cylinder (7). The two ends of each transverse pull rod (8) are respectively connected with a sliding block (5). The invention is of simple structure and applicable for various stereo garages.

Description

technical field [0001] The invention relates to the key technology of accessing vehicles in a three-dimensional garage, and proposes a walking trolley of a vehicle accessing device with a high degree of automation. Background technique [0002] At present, many trolleys in the existing three-dimensional garages use clamping arms to access vehicles. This structure has a large number of hydraulic cylinders, and the clamping arms are single-point support cantilever beams, which are easy to deform. The service life is shorter. The four wheels are synchronously driven by the transmission shaft, the transmission chain is long, the structure is complicated, and the reliability is poor. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a novel V-shaped clamp arm type hydraulic traveling trolley, which can realize two-way vehicle access. [0004] The technical solution is: the walking trolley includes a walki...
