Auxiliary mechanism for assisting caterpillar operation device to walk downstairs

Abstract

The invention provides an auxiliary mechanism for assisting a caterpillar operation device to walk downstairs. The auxiliary mechanism comprises a supporting component which can extend to a position obliquely below the advancing direction of a caterpillar operation device body, wherein the supporting component has the effects of supporting and buffering when the caterpillar operation device walks downstairs, so that the phenomenon that because the caterpillar operation device suddenly accelerates to advance obliquely downwards, the caterpillar operation device turns over is avoided. The auxiliary mechanism is simple in structure, small in size, low in cost, reliable to operate and convenient to use, and when the auxiliary mechanism for assisting the caterpillar operation device to walk downstairs is not used, and walking and normal operation of the caterpillar operation device are not influenced; the auxiliary mechanism has a wide market prospect and a wide development space, and has a high popularization value.

Description

technical field [0001] The invention relates to engineering operation equipment, in particular to a step-down auxiliary mechanism of a crawler type operation device. Background technique [0002] With the vigorous development of my country's modernization, a large number of engineering operation devices that perform different functions have appeared in engineering construction and emergency rescue to meet the operational needs of drainage, lighting, excavation, and emergency rescue. Although there are many types of engineering operation devices, most of the engineering operation devices can only stay away when encountering stairs. [0003] At present, in order to solve the problem that engineering operation devices cannot go up and down stairs, crawler-type operation devices are generally used. The crawler has a large ground area and strong climbing ability, and can smoothly, quickly and safely pass through various steep road conditions such as stairs. However, when the cra...

Problems solved by technology

However, when the crawler-type operating device is going down the stairs, the crawler belt slowly approaches the stair step. When the center of gravity of the crawler-type operating device passes the stair step, due to a sudden change in the force direction, the crawler-type operating device will suddenly accelerate downward obliquely. This moment can easily cause a rollover

The difficulty of controlling the step-down process is quite high. Even operators who have mastered very skilled driving skills and rich experience are prone to make mistakes. Great personal danger to pedestrians and drivers (particularly with manned tracked work units) in the vicinity of stairs
