Abstract

The invention discloses a roll-over protective device of engineering vehicles based on continuous shearing and energy absorption, which is mounted on the rear frame of the engineering vehicles and consists of a steel structural framing and two metal-shearing and energy-absorbing mechanisms; wherein, the metal-shearing and energy-absorbing mechanisms are respectively mounted on the upper end insidethe steel structural framing; the assembling of a shearing board, a sheared board, a Y-shaped sheared board are welded and assembled by a fixed beam to form the metal-shearing and energy-absorbing mechanism. In the invention, the steel structural framing is provided with a metal-shearing and energy-absorbing mechanism, so when engineering vehicle rolls over sidewise, the shearing board of the metal-shearing and energy-absorbing mechanism is contacted with the ground at first, and shears the outermost end of the sheared board; in the process of shearing, outside impact energy is absorbed in large amount, thus reducing parts of energy absorption of the steel structural framing, further ensuring enough living space in driving cabs and protecting drivers from injuries.

Description

technical field [0001] The invention relates to a protection device for an engineering vehicle, in particular to a continuous shearing energy-absorbing rollover protection device for an engineering vehicle. Background technique [0002] Existing engineering vehicles, such as loaders or excavators, are prone to side rollover due to the complex geographical environment during construction. Since the cabs of existing engineering vehicles are not considered in the process of vehicle rollover during the design and manufacturing process, , The weight of the car itself will flatten the cab, so that the driver does not have enough living space. Even if there is a rollover protection device, its structure is not reasonable enough. When a rollover occurs, the existing rollover protection device cannot meet the requirements of protecting the driver due to the weight of the vehicle and the impact force generated during the rollover process. The driver was seriously injured or killed. ...
