The invention belongs to the technical field of lifting appliances, and particularly relates to automatic lossless hoisting equipment for a vehicle frame. The automatic lossless hoisting equipment for the vehicle frame comprises a grabbing arm, the inner side wall of the bottom of the grabbing arm is fixedly connected with a first piston cylinder, a first piston rod is slidably connected into the first piston cylinder, a second piston cylinder is fixedly connected to the inner side wall of the grabbing arm, a second piston rod is slidably connected into the second piston cylinder, a first ventilation pipe is communicated between rodless cavities of the first piston cylinder and the second piston cylinder; the second piston cylinders are additionally arranged on the side walls of the grabbing arms, and the second piston rods are matched with the first piston cylinders and the first piston rods, so that direct contact between the grabbing arms and the vehicle frame is changed into an air cylinder supporting contact, the vehicle frame deformation problem caused by direct contact between the grabbing arms and the vehicle frame is reduced, and protectiveness is improved when the hoisting equipment transports the vehicle frame.

    本发明属于吊具技术领域,具体的说是一种自动化车架无损吊装设备,包括抓臂;所述抓臂的底部内侧壁固接有第一活塞缸;所述第一活塞缸内部滑动连接有第一活塞杆;所述抓臂的内侧壁固接有第二活塞缸;所述第二活塞缸内部滑动连接有第二活塞杆;所述第一活塞缸与第二活塞缸无杆腔之间连通有第一通气管;通过在多个抓臂的侧壁增加有第二活塞缸、第二活塞杆与第一活塞缸、第一活塞杆的配合,可将抓臂与车架的直接接触改变为气缸支撑接触,减少抓臂与车架直接接触而导致的车架形变问题,增加吊装设备运输车架时的保护性。
