Utility Model Content

[0003] The technical problem solved by the utility model is that the main bearing cap of a diesel engine may be bumped and scratched during transportation.

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions: a diesel engine body online hook, including a hook body, a lifting ring is provided on the top of the hook body, a hook portion is provided at the bottom of the hook body, the hook portion includes a bending portion and a hook head, a support block is provided on the bending portion, the upper surface of the support block is arc-shaped, and the arc-shaped upper surface of the support block imitates the arc-shaped inner surface of the main bearing cover.

[0005] During production, the hook rope is passed through the hook ring. During hoisting, the hook is inserted into the groove of the main bearing cap, the main bearing cap is positioned on the support block, the arc-shaped inner surface of the main bearing cap matches the arc-shaped upper surface of the support block, and the main bearing cap is stably positioned on the hook to avoid bumps and scratches during transportation.

[0006] The bending portion is welded with a support block fixing plate, and the support block is mounted on the support block fixing plate through a connecting piece.

[0007] A pair of through holes is provided on the support block fixing plate, a pair of threaded holes aligned with the pair of through holes are provided on the support block, and threaded connectors matched with the through holes and the threaded holes install the support block on the support block fixing plate.

[0008] As an improvement, a pipe fitting is sleeved on the hook head, and the top end of the pipe fitting is higher than the highest point of the main bearing cap positioned on the support block, so as to prevent the main bearing cap from falling off when shaking during hoisting.

[0026] like Figures 1 to 3 A diesel engine body upper line hook comprises a hook body 10, a lifting ring 11 is arranged on the top of the hook body, a hook portion 12 is arranged on the bottom of the hook body, the hook portion comprises a bending portion 13 and a hook head 14, a support block 20 is arranged on the bending portion, the upper surface of the support block is arc-shaped, and the arc-shaped upper surface 21 of the support block is shaped like the arc-shaped inner surface of the main bearing cover.

[0027] The bent portion 13 is welded with a support block fixing plate 30 , and the support block 20 is mounted on the support block fixing plate via a threaded connector 40 .

[0028] like Figure 6 , Figure 7A pair of through holes 31 are provided on the support block fixing plate 30, and a pair of threaded holes 22 aligned with the pair of through holes are provided on the support block 20. A threaded connector 40 matching the through holes and the threaded holes installs the support block on the support block fixing plate.

[0029] During production, the hook rope is passed through the hook ring 11. During hoisting, the hook 12 is inserted into the groove of the main bearing cap, the main bearing cap is positioned on the support block 20, the arc-shaped inner surface of the main bearing cap matches the arc-shaped upper surface 21 of the support block, and the main bearing cap is stably positioned on the hook to avoid bumps and scratches during transportation. Figure 8 , Fig. 9 A pipe fitting 50 can be sleeved on the hook head 14, and the top of the pipe fitting is higher than the highest point of the main bearing cap positioned on the support block 20. In this way, the main bearing cap can be prevented from falling off when shaking during hoisting.
