Wheel-tracked combined type walking platform

Abstract

The invention discloses a wheel-tracked combined type walking platform, comprising a track wheel, a track and a rack; the walking platform is further provided with walking wheels, a supporting bracket and a bidirectional hydraulic cylinder, wherein at least three walking wheels are provided and distributed at both ends of the rack; one end of the supporting bracket is connected with a wheel shaft of the walking wheel, and the other end of the supporting bracket is connected with the rack through a hinge; and the bidirectional hydraulic cylinder is arranged between the rack and the supporting bracket. Based on the platform with four wheels, the track is installed at an abdominal part of the platform to assist the platform barrier-crossing. Simultaneously, the height of each walking wheel is designed to be adjustable, and the height is adjusted by the hydraulic cylinder. A part of the track is on the ground or off the ground by adjusting the height of the walking wheel. When the platform is driven on the flat road, the height of the walking wheels can be reduced to cause the track to be partially off the ground, so that the quick walking of the walking platform is realized.

Description

[0001] technical field [0002] The invention relates to a walking platform for transport machinery, in particular to a wheel-track compound walking platform. Background technique [0003] At present, most of the compound walking platforms have wheel-track compound type, wheel-foot compound type, and wheel-track-leg compound type. When the wheel-track compound walking platform is running on a flat road, it adopts a four-wheel landing motion mode. This mode has the motion characteristics of ordinary wheeled walking platforms, can move forward, backward, and turn, and has the characteristics of small frictional resistance, low energy consumption, flexible and stable movement, and small working space, etc., and can realize long-distance movement of the walking platform on flat roads Requirements to ensure that it enters the workplace quickly and efficiently. The current conventional wheel-track compound walking platform has the following disadvantages: First, the direct compo...

Problems solved by technology

The current conventional wheel-track compound walking platform has the following disadvantages: First, the direct compound form of wheel-track (attach two tracks to the inner side of the walking wheel), although it has enhanced its ability to cross ravines and soft ground, it has not improved The chassis of the walking platform

When a large obstacle appears directly below the platform, it still cannot effectively overcome the obstacle; secondly, the height of the walking platform cannot be adjusted, and the transmission system of the walking wheel and the track is relatively complicated
