With the growing of the automobile manufacturing industry and the increasing investment, it has become an essential requirement to reduce the labor intensity of workers and improve the working environment. The subframe of a box-shaped body-on-frame off-road vehicle needs to be hoisted so that it can be stably placed on the subframe sub-assembly fixture designated on the production line to achieve the sub-assembly of the frame structure subframe of the vehicle model. The traditional hoisting method usually hooks the process holes of the subframe through three groups of hooks and then hoists it to the sub-assembly fixture. However, due to the product structure, many hanging points cannot be set at appropriate positions, resulting in the inability to hoist the subframe in balance, and thus collisions and abrasions occur between the subframe and the sub-assembly fixture, affecting the product quality and the working efficiency at the same time. Therefore, it is necessary to invent a new subframe hoisting device. Content of the Utility Model

The upper end of the gravity center adjusting hanging part 3 is used to connect to an electric hoist hook.
[0021] To facilitate the connection between the hook chain assembly 2 and the connecting rod 1, the hook chain assembly 2 includes a D-shaped shackle 21. The D-shaped shackle 21 is connected to the connecting seats 11 on the left and right sides of the connecting rod 1 by screwing. A chain 23 is connected to the D-shaped shackle 21. The lower end of the chain 23 is connected to a hook 24. The number of links of the chain 23 can be set according to actual needs to ensure the consistency of the hoisting height.
[0022] To facilitate the connection between the chain 23 and the chain seat 21 and the hook 24 respectively, a set of butterfly clips 22 are connected to both the upper and lower ends of the chain 23. The two sets of butterfly clips 22 are respectively connected to the D-shaped shackle 21 and the hook 24.
[0023] To facilitate moving back and forth along the length direction of the balance boom 13 and locking and fixing with bolts and nuts, the gravity center adjusting hanging part 3 includes an upper fixing plate 31 and a lower fixing plate 32 arranged in parallel. The upper fixing plate 31 and the lower fixing plate 32 clamp the upper and lower end faces of the balance boom 13 by screwing.
[0024] To facilitate the connection with devices such as an electric hoist hook to lift the entire device, a hook seat 33 is fixedly connected to the upper end face of the upper fixing plate 31. A hook hole 34 is arranged on the hook seat 33. The hook hole 34 is used to connect to an electric hoist hook. The hook hole 34 can be used to connect to the KBK track and the lifting chain and hook of the electric hoist. During normal production, employees operate the electric hoist, and through the cross-shaped track at the work station, move the operation unit to the designated material placement area beside the line for hoisting the frame structure subframe.
[0025] To limit the position by resisting the upper end face of the subframe during hoisting and prevent one side of the subframe from tilting up, limiting rods 12 are fixedly connected to the left and right sides of the connecting rod 1. A limiting plate 4 is fixedly connected to the limiting rod. The limiting plate 4 is used to limit the upper end face of the subframe.
