Description

Technical Field

[0001] The utility model relates to the technical field of engine flywheel housing hoisting, specifically, an efficient and universal engine flywheel housing hook. Background Art

[0002] In the existing automobile manufacturing and maintenance industries, the hoisting operation of the engine flywheel housing is a key and frequent task. Traditional hoisting tools usually face the following main technical problems:

[0003] Firstly, existing hoisting equipment is often designed for specific models of engine flywheel housings and lacks the necessary universality. This results in factories having to equip different models of engines with multiple special hoisting tools, which not only increases the equipment procurement cost, but also occupies a large amount of storage space. Moreover, when it is necessary to hoist flywheel housings of different models, the operation of replacing the lifting tool also reduces work efficiency.

[0004] Secondly, many existing hoisting tools require complex manual adjustments during operation to ensure that the flywheel housing can be stably suspended and transferred. These complex adjustment processes are not only time-consuming, but also require high skills from operators, increasing the difficulty of work. In a high-pressure and fast-paced work environment, the complexity of the operation multiplies the probability of errors, which may lead to damage to the flywheel housing or safety accidents.

[0005] In addition, existing hoisting tools often lack sufficient stability during actual operation. The swing of the flywheel housing during hoisting may cause damage to the flywheel housing itself or other components on the assembly line, and this instability is particularly prominent when hoisting heavier or larger flywheel housings.

[0006] Finally, the safety issues of existing hoisting solutions cannot be ignored. Due to the lack of a design that can flexibly adapt to different hoisting angles, operators must take additional safety measures during hoisting to prevent the accidental slipping or flipping of the flywheel housing, and these additional measures further increase the complexity and time cost of the operation.

[0007] In view of the many problems in the above background art, there is an urgent need for a new type of hoisting tool to solve these defects and improve the universality, efficiency, stability and safety of hoisting operations.

[0008] The prior art, such as the patent No. CN 207632330U held by Kunshan Sany Power Co., Ltd., has a hoisting tool design that is particularly suitable for a specific model of flywheel housing, providing a rotating hoisting mechanism and a supporting part, enabling the flywheel housing to maintain a vertical state during hoisting. Although this hoisting tool performs well in terms of hoisting stability and safety, its design is mainly suitable for flywheel housings with a specific structure and does not have the flexibility and universality to handle different models of flywheel housings.

[0032] Please refer to Figure 1 and Figure 2 shown, a highly efficient and universal engine flywheel housing lifting hook, comprising:

[0033] Hook plate 1, arranged in an L shape;

[0034] Clamping plate 2, fixedly connected to the end of the vertical section 11 of the hook plate 1 and arranged parallel to the horizontal section 12 of the hook plate 1;

[0035] Clamping plate 3, the plate body of which is hinged to the end of the clamping plate 2, and the clamping plate 3 is arranged at one end of the clamping plate 2 opposite to the vertical section 11 of the hook plate 1;

[0036] One end of the clamping plate 3 opposite to the vertical section 11 of the hook plate 1 is constructed with a hanging ring 4, and one end of the clamping plate 3 facing the vertical section 11 of the hook plate 1 extends into the space between the horizontal section 12 of the hook plate 1 and the clamping plate 2 to form a clamping groove 5.

[0037] In this way, by installing the hanging ring 4 on the hoisting equipment, and then embedding the end of the flywheel housing into the clamping groove 5, during the upward movement of the hanging ring 4, one end of the clamping plate 3 facing the horizontal section 12 of the hook plate 1 moves downward, and cooperates with the horizontal section 12 of the hook plate 1 to clamp the flywheel housing. At the same time, different clamping plates 3 can be replaced, so that the clamping groove 5 can adapt to flywheel housings of different specifications. It can quickly adapt to flywheel housings of various sizes and models.

[0038] The clamping plate 2 is composed of two fixed plates 21 arranged in parallel, and the vertical section 11 of the hook plate 1 and the clamping plate 3 are clamped between the two fixed plates 21.

[0039] Thus, by the clamping of the two fixed plates 21, the articulated movable part of the clamping plate 3 is protected, and the load-bearing stability of the entire lifting hook is improved.

[0040] Furthermore, one end of the clamping plate 3 facing the vertical section 11 of the hook plate 1 is provided with a clamping groove 6, and the clamping groove 6 is arranged on the surface of the clamping plate 3 facing the horizontal section 12 of the hook plate 1.

[0041] In this way, by adjusting and installing the clamping plate 3 with clamping grooves 6 of different shapes, the entire lifting hook can be adapted to flywheel housings of various different specifications. By the clamping connection between the clamping groove 6 and the surface of the flywheel housing, the flywheel housing can be clamped more stably during the hoisting and transfer process, improving the hoisting safety.

[0042] In addition, the clamping plate 3 is articulated with the clamping plate 2 through a detachable articulation mechanism. The detachable articulation mechanism includes a pin shaft 7 that penetrates through the clamping plate 3 and the clamping plate 2 at the same time. The pin shaft 7 is in sliding contact with the clamping plate 3 and the clamping plate 2, and split pins 8 are detachably installed at both ends of the pin shaft 7.

[0043] In this way, by removing the split pins 8, the pin shaft 7 can be disassembled, ensuring the convenience of quick disassembly and assembly of the entire lifting hook, which is beneficial to the daily maintenance of the lifting tool and the quick replacement of the clamping plate 3.

[0044] Furthermore, washers 9 are sleeved at both ends of the pin shaft 7, and the washers 9 are arranged between the split pins 8 and the outer wall of the clamping plate 2.

[0045] In this way, the washers 9 are used to avoid a large amount of wear between the split pins 8 and the outer wall of the clamping plate 2 during the use of the lifting hook.

[0046] Furthermore, a through hole 10 is provided at one end of the clamping plate 3 opposite to the vertical section 11 of the hook plate 1. The lifting ring 4 passes through the through hole 10, and the lifting ring 4 is articulated with the clamping plate 3.

[0047] In this way, by the free rotation of the lifting ring 4, the unexpected torque caused by the movement of the hoisting machinery can be reduced, avoiding the risk of possible damage to the lifting tool and the flywheel housing.

[0048] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
