[0002] According to the body terminology standards and the definition in textbooks, the body in white refers to the body that has been welded but not yet painted. During the welding process of the body in white assembly, the heavier sub-assembly parts must be lifted by a crane during the installation process.

[0003] During the installation of the body-in-white top cover assembly, since the top cover forms a closed structure with the body on all sides, it is necessary to design a set of hoists to hoist the top cover from the upper surface of the top cover to ensure convenient and reliable hoisting. At present, most hoisting methods at home and abroad use welding lifting ears, and the hoist needs to be welded and fixed to the top cover, which will cause damage to the top cover on the one hand; on the other hand, the production and installation of the hoist, as well as the repair and polishing of the top cover after removal require manpower, material and financial resources, which not only increases the construction cost, but also makes the overall hoisting operation inconvenient, and also affects the overall progress of the body-in-white assembly welding; and during hoisting, the top cover is prone to tilt due to factors such as different lengths of wire ropes and uneven force on the hoisting points, which affects the stability during hoisting and movement and reduces the safety of the hoist.

[0029] 2. The top cover hoist, through the three adjustment components, can adjust the three lifting chains used to connect the external overhead crane equipment and the three lifting points on the top cover body during the hoisting process, and adjust the heights of the self-locking hooks at the lower ends of the three lifting chains. After the three self-locking hooks are connected to the three lifting points on the top cover body, the three lifting chains are all in a taut state. After the top cover body is lifted, it can maintain a stable horizontal state to ensure balance. It is not easy for the top cover to tilt due to uneven force and other factors, thereby ensuring stability during hoisting and moving, and effectively improving the safety of the hoist when in use.

[0054] One of the self-locking hooks 10 passes through the bulletproof window assembly hole 24 and is sleeved on the third lifting eye nut 28. Before lifting the top cover body 1, the connecting seat 25 can be pre-installed on the bottom of the top cover body 1, and the third lifting eye nut 28 can be rotated to pass through the installation hole 27 and be screwed on the connecting nut 26, thereby forming a third lifting point.

[0055] Optionally, the adjustment assembly 9 includes a connecting ring 29 sleeved on one of the self-locking hooks 10, a limiting rod 32 movably installed in the connecting ring 29, and a mounting groove 33 and a limiting thread groove 34 provided on the connecting ring 29;

[0056] The outer wall of one end of the limiting rod 32 is provided with an external thread 35 threadedly connected to the limiting thread groove 34. When the three lifting chains 8 need to be connected to the first lifting member 2, the second lifting member 3 and the third lifting member 4, the limiting rod 32 can be rotated first to disengage the limiting rod 32 from the limiting thread groove 34, and the installation groove 33 is exposed. Then, the self-locking hook is set on the connecting ring 29 through the installation groove 33, and the self-locking hook at the corresponding position is set on the first lifting member 2, the second lifting member 3 and the third lifting member 4. Then, the staff can pull them A lifting chain 8 is installed and kept in a taut state, and then the lifting chain 8 is sleeved on the connecting ring 29 through the installation groove 33, and the lifting chain 8 is in a relatively taut state.

After the three hanging chains 8 are connected to the first hanging piece 2, the second hanging piece 3 and the third hanging piece 4 respectively, and the three hanging chains 8 are kept in a taut state, the reinforcement frame 38 can be hooked on the edge of the top cover body 1 or the edge of the bulletproof window assembly hole 24, so that the reinforcement frame 38 is placed at the bottom of the top cover body 1, and the strong magnetic block 40 is placed on the upper surface of the top cover body 1 to adsorb the reinforcement frame 38, so that the reinforcement frame 38 is stably placed on the top cover body 1, and then the connecting hanging chain 8 is connected to the top cover body 1. The hook 36 is hooked on one of the lifting chains 8, and the auxiliary chain 37 is in a taut state. The installation of the mulberry fruit reinforcement assembly 11 is completed in sequence according to this method. When the top cover body 1 is hoisted, if the first hoisting piece 2, the second hoisting piece 3 and the third hoisting piece 4 are loose, the auxiliary chain 37 can continue to hoist the top cover body 1 to avoid safety hazards. At the same time, through the cooperation of the three auxiliary chains 37 in the three reinforcement assemblies 11, the stability of the hoisting device when hoisting the top cover can be improved, ensuring the safety of the hoisting process.

[0062] Optionally, the connecting lifting ring 6 adopts an elliptical fully enclosed structure. The elliptical fully enclosed structure can effectively reduce the stress concentration at the connecting lifting ring 6 during the lifting process, thereby improving the overall stability of the lifting device, and also improves the safety of the lifting device during use.

[0063] Optionally, several of the first screw holes 15 are arranged at equal intervals on the support plate 13. The first screw holes 15 arranged at equal intervals can ensure that the support plate 13 is subjected to uniform force as a whole, thereby avoiding affecting the overall performance and safety of the support plate 13. At the same time, several first screw holes 15 are opened at equal intervals, so that the distance between them can be controlled when the position of the first lifting eye bolt 16 is adjusted.
