For example, the lifting tool is used to carry a heavy camshaft chamber. The camshaft chamber has a hollow camshaft chamber body. Since the camshaft and camshaft gear are installed in the camshaft chamber body, the camshaft chamber is heavy and it is difficult to move it manually.

[0003] On the current engine assembly line, some camshaft chambers are equipped with two camshafts. The above-mentioned camshaft chambers need to sub-assemble the two camshafts into the chamber on the top of the cylinder head. Therefore, there are many sub-assemblies in the above-mentioned camshaft chambers, the structure is complex, and the overall weight of the camshaft chamber is heavy. At the same time, the hook part of the lifting device on the market has a complex structure. Due to the space limitation in the camshaft chamber, it is difficult to enter the camshaft chamber and effectively lift the camshaft. Therefore, the existing lifting device is difficult to apply to the transportation of the above-mentioned camshaft chamber with two camshafts. Since the above-mentioned camshaft chamber needs to be assembled to the positioning hole on the top of the engine, the operator relies on manual transportation, which is difficult to install and has low operating efficiency. There is also a risk of workpieces falling and causing safety accidents. Utility Model Content

[0025] like Figure 1As shown, the utility model provides a lifting tool, a connecting assembly 1, a hook 6 and an elastic member 5, the hook 6 is two, one end of the hook 6 is provided with a hook portion, the hook portion has a hook end, the other end of the hook 6 is a connecting end, the connecting end is movably connected to the connecting assembly 1, the connecting ends of the two hooks 6 are close to each other, the hook ends of the two hooks 6 are close to each other, and the directions of the two hook ends are away from each other; the elastic member 5 is arranged between the two hooks 6 and acts on the two hooks 6 respectively, and the elastic member 5 is used to drive the hook ends of the two hooks 6 to separate from each other. By setting the elastic member 5, the two hooks 6 can be kept in a separated state, when the two hooks 6 are brought close to each other by an external force, the distance between the two hooks 6 becomes smaller, and it is convenient to extend into the object to be lifted, and after the external force is removed, the two hooks 6 are automatically separated to be hooked on the double shafts respectively, so as to facilitate the lifting of the object to be lifted, and the operation is more convenient when using the lifting tool, and the lifting tool has high practicality as a whole, simple structure, low cost, and good economic benefits. The lifting tool in the present application is particularly suitable for a camshaft housing 9 having two camshafts 8. When the gap between the two camshafts 8 in the camshaft housing 9 is small, the two hooks 6 can approach each other and enter the gap to lift the two camshafts 8 respectively. In the embodiment, the connecting assembly 1 includes a lifting lug 2, which is used to connect with an electric hoist.

[0026] Among them, the hook 6 has two hooks, and the two hooks are spaced apart, and the arrangement direction of the two hooks is perpendicular to the extension direction of the hook end. By arranging two hooks on one hook 6, it is possible to ensure that the object to be lifted does not shift when the lifting tool lifts the object to be lifted, and to avoid the object to be lifted shifting during lifting, slipping out of the lifting tool, and causing a safety accident. For example, for the camshaft chamber 9, when the gear is pressed onto the camshaft 8, the center of gravity of the camshaft chamber 9 shifts, and the center of gravity is not at the center point of the camshaft 8. Therefore, arranging two hooks on one hook 6 can balance the center of gravity of the camshaft 8, so that when the lifting tool lifts the camshaft chamber 9, the camshaft chamber 9 does not shift, thereby ensuring the safe lifting and assembly of the camshaft chamber 9.

[0027] Specifically, a support rod 7 is provided between the two hooks of the same hook 6, and the support rod 7 extends along the arrangement direction of the two hooks of the hook 6 and is respectively connected to the two hooks. Since the two hooks are arranged at a distance, there is a distance between the connection end and the projection of the hook along the distribution direction of the two hooks. By providing the support rod 7, the support rod 7 can share the lateral force received by the hook 9 of the lifting tool when lifting the object to be lifted, increase the support strength between the two hooks, ensure the stability of the lifting tool when lifting, and avoid the situation that the two hooks 9 are close to each other and the hook 9 is damaged due to the insufficient support of the two hooks 9 when the two hooks are lifting the object to be lifted due to the excessive gravity of the object to be lifted. In this embodiment, the support rod 7 and the connection end of the corresponding hook 6 form a triangle. Due to the high stability of the triangle, the support rod 7 and the connection end of the corresponding hook 6 form a triangle, which can increase the support strength of the hook 6 when working and improve the stability of the lifting tool when working.

[0028] The connecting end of the hook 6 is rotatably connected to the connecting assembly 1. The rotatable connection facilitates the two hooks 6 to move closer to or farther from each other, and the rotatable connection structure is simple, which is convenient for production and assembly. In some embodiments, the connecting end of the hook 6 can realize relative movement between the two hooks 6 through the displacement groove and the movable block 4 slidably arranged in the displacement groove. The connection method between the connecting end of the hook 6 and the connecting assembly 1 can be adjusted according to actual use requirements.

[0029] The elastic member 5 is a spring. The spring has the advantages of being easy to deform, highly elastic, and inexpensive. The use of the spring can reduce the manufacturing cost of the lifting tool while ensuring the elastic force required by the lifting tool. The type of the elastic member 5 can be adjusted according to actual use requirements.

[0030] Among them, the lifting tool also includes two movable blocks 4 set at intervals, the elastic member 5 is set between the two movable blocks 4, and the movable block 4 is set on the corresponding hook 6. By setting the movable block 4 on the elastic member 5, it is convenient for the operator to squeeze the elastic member 5 through the movable block 4 to bring the two hooks 6 closer. The movable block 4 can increase the force area of ​​the operator when using the lifting tool, increase the comfort when using the lifting tool, and improve the overall practicality of the lifting tool. In this embodiment, the movable block 4 is plate-shaped, and the plate-shaped movable blocks 4 are relatively arranged. The movable block 4 is plate-shaped, and the plate-shaped movable block 4 is relatively thin, which is convenient for the operator to control the two plate-shaped movable blocks 4 with one hand, squeeze the elastic member 5, and bring the two hooks 6 closer, thereby increasing the practicality and applicability of the lifting tool. In some embodiments, a shield can be set at the movable block 4 of the lifting tool, and the elastic member 5 and the rotating shaft of the hook 6 are surrounded on all sides by the shield and the movable block 4 to improve the overall aesthetics of the lifting tool.

[0031] In detail, a handle 3 is provided on the movable block 4. The handle 3 can facilitate the operator to operate the lifting tool, increase the comfort of using the lifting tool, and prevent the operator's hand from being separated from the movable block 4 when squeezing the elastic member 5 through the movable block 4, resulting in operational errors.

[0032] In summary, by setting the elastic member 5, the two hooks 6 can be kept separated. When the two hooks 6 are brought close together by external force, the distance between the two hooks 6 becomes smaller, which is convenient for inserting into the object to be lifted. After the external force is removed, the two hooks 6 are automatically separated to be hooked on the double shafts respectively, which is convenient for lifting the object to be lifted. After the elastic member 5 is set, the process of hooking the double shafts with the hooks 6 can be simplified, and the operation is more convenient when using the lifting tool, which improves the overall practicality of the lifting tool. The lifting tool has a simple structure, low cost, and good economic benefits.
