[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0026] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0027] As Figure 1 and Figure 2 and Figure 3 shown, a tool for vertically lifting a bearing includes a first suspension rod 1, a second suspension rod 2, and a coupling shaft 3. The first suspension rod 1 and the second suspension rod 2 are rotatably arranged on the coupling shaft 3. The coupling shaft 3 is located at the middle position between the first suspension rod 1 and the second suspension rod 2. The first suspension rod 1 and the second suspension rod 2 are cross - arranged, and the first suspension rod 1 and the second suspension rod 2 are cross - arranged on the coupling shaft 3. The first suspension rod 1 and the second suspension rod 2 can rotate on the coupling shaft 3.

[0028] The first suspension rod 1 and the second suspension rod 2 are formed by bending. In this example, the first suspension rod 1 and the second suspension rod 2 are bent twice, and both the first suspension rod 1 and the second suspension rod 2 have arcs. The distance between the tops of the first suspension rod 1 and the second suspension rod 2 is less than the distance between the bottoms. In this way, when the distance between the tops of the first suspension rod 1 and the second suspension rod 2 is the smallest, there is still a distance between the bottoms of the first suspension rod 1 and the second suspension rod 2. At this time, it is also the time when the bottoms of the first suspension rod 1 and the second suspension rod 2 clamp the bearing 4 most tightly.

[0029] A first pin 11 is arranged at the bottom of the first suspension rod 1, and a second pin 21 is arranged at the bottom of the second suspension rod 2. The first pin 11 and the second pin 21 are arranged opposite to each other, so that the first pin 11 and the second pin 21 fork up the bearing 4 from both sides.

[0030] The first pin 11 and the second pin 21 are used to jointly clamp the bearing 4. The first pin 11 and the second pin 21 can approach and move away from each other. When the first pin 11 and the second pin 21 approach each other, the first pin 11 and the second pin 21 can jointly lift the bearing 4. Other equipment lifts the first boom 1 and the second boom 2, and then transports the bearing 4 to the set position. Then the first pin 11 and the second pin 21 move away from each other, and the bearing 4 is put down.

[0031] A first hanging rod 12 is provided at the top of the first boom 1. The first boom 1 is rotatably arranged on the first hanging rod 12. By lifting the first hanging rod 12, the first boom 1 and the first pin 11 are lifted.

[0032] Furthermore, a first lifting ring 5 is provided on the first hanging rod 12. The first lifting ring 5 connects both ends of the first hanging rod 12. Lifting is achieved through the first lifting ring 5, and the first lifting ring 5 is beneficial for lifting and transporting.

[0033] A second hanging rod 22 is provided at the top of the second boom 2. The second boom 2 is rotatably arranged on the second hanging rod 22. The second hanging rod 22 assists in lifting the second boom 2 and the second pin 21.

[0034] Furthermore, a second lifting ring 6 is provided on the second hanging rod 22. The second lifting ring 6 connects both ends of the second hanging rod 22. Lifting is achieved through the second lifting ring 6, and the second lifting ring 6 is beneficial for lifting and transporting.

[0035] The first lifting ring 5 and the second lifting ring 6 are lifted simultaneously, so that the first pin 11 and the second pin 21 simultaneously hook up the bearing 4.

[0036] The first pin 11 and the second pin 21 are arranged in a staggered manner to prevent the first pin 11 and the second pin 21 from colliding. The first pin 11 and the second pin 21 staggeringly lift the bearing 4, and can also prevent the bearing 4 from tilting and falling off.

[0037] The above embodiments are only used to illustrate the technical concept and characteristics of the present invention. The purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it accordingly. It cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit and essence of the present invention should be covered within the protection scope of the present invention.
