A step-down auxiliary mechanism for a crawler-type operating device

Abstract

The invention provides an auxiliary mechanism for lower steps of a crawler-type working device, which includes a support member that can extend to the obliquely below the direction of travel of the crawler-type working device body, and plays a role of supporting and buffering the lower steps of the crawler-type working device, preventing the crawler-type working device from Sudden acceleration to the downward direction causes the vehicle to overturn. The step-down auxiliary mechanism is simple in structure, small in size, low in cost, reliable in operation, easy to use, and the step-down auxiliary mechanism does not affect the walking and normal operation of the crawler operating device when it is not in use. It has a broad market prospect and development space, and has a very high promotion 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
