Self-rescue device after bulldozer mires down in mud
The invention discloses a self-rescue device after a bulldozer mires down in mud. The self-rescue device comprises a machine body of an additional device disposed on the rear portion of the bulldozer.A telescopic cavity is formed in the machine body, a telescopic mechanism is disposed in the telescopic cavity, a power arm is mounted in the telescopic cavity in a left-right sliding manner, and theright portion of the power arm is provided with a steering cavity. The steering cavity is internally provided with a steering mechanism. The device is mounted on the rear portion of the bulldozer. When the bulldozer mires down in a mud pond or swamp in the advancing process and cannot be extricated, the device is started, the power arm extends to the rear portion of a bulldozer body, the tail endof the power arm is provided with a device capable of fixing the device into a solid ground, and after the device is fixed, the power arm is drawn back, and the bulldozer can be pulled out from the mud pond by using reaction force.
本发明公开了一种推土机陷入泥潭中后的自救设备，包括设置于推土机后部的附加设备的机体，所述机体中设置有伸缩腔，所述伸缩腔中设置有伸缩机构，所述伸缩腔中左右滑动安装有动力臂，所述动力臂右部设置有转向腔，所述转向腔中设置有转向机构，该设备安装于推土机后方，当推土机前进过程中陷入泥塘或是沼泽中不能自拔的时候，启动该设备，能向车体后方伸出一根动力臂，动力臂末端设置有能将设备固定到结实地面中的装置，当装置固定后收回动力臂，就能以一个反作用力将推土机从泥塘中拉出。
