Stair and land amphibious barrier-free transport vehicle

Abstract

The invention discloses a stair and land amphibious barrier-free transport vehicle which comprises a first vehicle body and a second vehicle body. A sleeve is installed at the end of the first vehicle body. A lifting column is installed at the end of the second vehicle body and sleeved with the sleeve. A lifting block is arranged in the sleeve. The lifting column is provided with a sliding groove capable of sliding relative to the lifting block. The lifting block is in a T shape. The sliding groove in the lifting column is a T-shaped groove matched with the lifting block. The top end of the lifting column is provided with a fixed pulley and connected with a reeling device at the bottom through a steel wire rope. The steel wire rope is further fixed to the upper end and the lower end of the lifting block and used for relative sliding of the upper end and the lower end of the lifting block. A gravity center adjusting table is installed at the outer portion of the sleeve and is circular. Through the relative movement of the vehicle bodies, equipment is transported and moved on stairs without slopes, and the gravity center adjusting table 3 can not only adjust the gravity center but also load goods.

Description

[0001] This application is a divisional application with the filing date in China on December 22, 2014, the application number 201410800645.3, and the name "ladder walking mechanism". technical field [0002] The invention relates to a step-land amphibious barrier-free transport vehicle. Background technique [0003] In the process of equipment transportation on the construction site, if the construction space is limited, it is impossible to lay slope transportation channels, and the construction encounters huge difficulties. The existing technology is still unable to realize the barrier-free amphibious transportation of the equipment, and only heavy hoisting mechanisms can be used. bring a huge cost burden. [0004] In many places such as hospitals, banks, parks, shopping malls, subway stations and other public places, there are still many steps, which bring huge troubles to the transportation of various equipment. The existing ladder climbing equipment has crawler type and...

AI Technical Summary

Problems solved by technology

The crawler type has the problem of difficulty in walking on a flat bottom, and the wheel set type has poor applicability to steps and cannot meet the comfort requirements. When the existing ladder climbing equipment is working, the entire equipment is in a tilted state, and there are problems with stability and comfort.
