Abstract
The invention discloses a cab type rollover protection structure. The cab type rollover protection structure consists of two protection covers, two buffering energy absorbers, a rollover protection structure main body and two anti-slip buffering energy absorption devices, wherein the two buffering energy absorbers construct two upper transverse beams of the rollover protection structure; the two anti-slip buffering energy absorption devices are fixedly connected to two upper longitudinal beams of the rollover protection structure respectively through a bottom plate; the two protection covers are arranged on the two anti-slip buffering energy absorption devices respectively in a sleeving way, and are fixedly connected to the upper longitudinal beams. In case of rollover of a vehicle, energy is buffered and absorbed through deformation of the buffering energy absorbers and anti-slip buffering energy absorption teeth, so that shock generated by collision of the rollover protection structure is reduced remarkably, and the personal safety of a driver is protected effectively. Meanwhile, a part of the anti-slip buffering energy absorption teeth are drilled into the ground, so that the vehicle can be effectively prevented from slipping along a slope, the slipping speed of the rollover vehicle is lowered, collision of the rollover vehicle with other objects is avoided or slowed down, and secondary injury of the driver is effectively prevented.
