[0026] The upper hanging frame 2 and the lower hanging frame 3 are arranged on the same side of the support frame 1, and the support frame 1 is connected to the upper hanging frame 2 and the lower hanging frame 3 respectively.

[0027] Among them, the spacing distance between the upper lifting frame 2 and the lower lifting frame 3 is the length of the support frame 1. The length of the support frame 1 can be selected according to the construction space of the installation position of the component 8 to be lifted, and this embodiment does not make further limitations.

[0028] The upper hanging frame 2 and the lower hanging frame 3 are arranged opposite to each other along the length direction of the supporting frame 1 .

[0029] Among them, the upper hanging frame 2 is arranged on a side of the lower hanging frame 3 close to equipment such as a crane, a gantry crane, and an electric hoist.

[0030] Among them, the length of the upper lifting frame 2 is greater than that of the lower lifting frame 3. The upper lifting frame 2 is used to connect the lifting equipment of equipment such as cranes, gantry cranes, electric hoists, etc., and the lower lifting frame 3 is used to connect the component 8 to be lifted, that is, the crosshead pressure body.

[0031] Specifically, a hoisting hole 21 is opened on the upper hoisting frame 2, and the hoisting hole 21 is located in the area outside the projection of the lower hoisting frame 3 on the upper hoisting frame 2, so as to realize the hoisting operation when there is no hoisting point directly above the component 8 to be hoisted.

[0032] A balancing block 4 is also provided on the upper hoisting frame 2 for balancing the weight of the component 8 to be hoisted.

[0033] Specifically, the balancing block 4 is located on the side of the lifting hole 21 away from the support frame 1, and uses the lever principle to balance the weight of the component to be lifted 8, so that the lifting tool has a self-balancing function, thereby preventing the component to be lifted 8 from colliding with other equipment due to shaking during the lifting operation, thereby improving the safety of the lifting operation.

[0034] In some possible embodiments disclosed in the present application, the support frame 1 is arranged vertically.

[0035] Among them, the support frame 1 is arranged vertically, that is, the lifting tool is arranged vertically. On the one hand, it is conducive to bearing the gravity in the vertical direction, so that the lifting tool can bear more loads; on the other hand, it is conducive to the operator to observe the rising and falling process of the component 8 to be lifted, and promptly discover and deal with possible problems.

[0036] In some possible embodiments disclosed in the present application, the upper hanging frame 2, the support frame 1 and the lower hanging frame 3 are combined to form a horizontal U-shaped structure.

[0038] Specifically, the opening of the lifting tool with a transverse U-shaped structure faces the horizontal direction.

[0039] In some possible embodiments disclosed in the present application, in the extension direction of the upper hanging frame 2, the spacing distance between the balancing block 4 and the hanging hole 21 is greater than the spacing distance between the part to be hoisted 8 and the hanging hole 21.

[0042] The horizontal distance between the component to be lifted 8 and the lifting hole 21 may be the arm length of the component to be lifted 8 .

[0043] Specifically, in the embodiment of the present application, the arm length of the balancing block 4 is greater than the arm length of the component to be lifted 8, so that when the weight of the balancing block 4 is less than the weight of the component to be lifted 8, the lifting tool can be self-balanced.

[0044] In some possible embodiments disclosed in the present application, a slide groove 22 is provided on the upper hanging frame 2, and the slide groove 22 extends in the same direction as the upper hanging frame 2.

It should be noted that when the position of the balancing block 4 changes, the length of the force arm of the balancing block 4 changes accordingly, so that the lifting tool can adjust the balancing block 4 to different positions according to the different weights of the parts 8 to be lifted, that is, for the different weights of the parts 8 to be lifted, the lifting tool has a self-balancing function, which increases the scope of application of the lifting tool.
