DETAILED DESCRIPTION

[0023] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0024] As Figure 1 and Figure 2 shown in the drawings, a lifting device for lifting a transmission case, comprising: a suspender 1, a connecting rod 2 and a load-bearing rod 3;

[0025] The suspender 1 is horizontally arranged, and the suspender 1 is provided with a connecting structure for connecting with a hoisting device;

[0026] The connecting rod 2 is vertically arranged, and the connecting rod 2 is fixedly connected between the suspender 1 and the load-bearing rod 3;

[0027] The load-bearing rod 3 is arranged horizontally and perpendicular to the suspension rod 1. The load-bearing rod 3 is located below the suspension rod 1. A first support plate 5 and a second support plate 6 are fixed on the load-bearing rod 3. The first support plate 5 and the second support plate 6 are staggered. The first support plate 5 is located above the second support plate 6. The first support plate 5 is provided with a first limiting groove 51 with an opening facing downward, and the second support plate 6 is provided with a second limiting groove 61 with an opening facing upward.

[0028] like Figure 3 As shown, in this embodiment, the working principle and working process of the transmission case lifting device of the present invention are explained by taking the transmission case 4 as an example. The transmission case 4 includes a case body 41, a sleeve 42 is fixed on the case body 41, and a sprocket mounting sleeve 43 is fixed on a transmission shaft of the case body 41. When lifting the transmission box 4, the hook of the lifting equipment is connected to the connecting structure, the sprocket mounting sleeve 43 is located in the first limiting groove 51, and the sleeve 42 is located in the second limiting groove 61. The first limiting groove 51 and the second limiting groove 61 clamp the transmission box 4, so that the transmission box 4 cannot move in the horizontal direction; because the box body 41 has a large mass, the box body 41 has a tendency to move downward around the connection point of the sleeve 42 and the second limiting groove 61, and the sprocket mounting sleeve 43 has a tendency to move upward around the connection point of the sleeve 42 and the second limiting groove 61, and the sprocket mounting sleeve 43 is just clamped by the first limiting groove 51, and the transmission box 4 cannot move in the vertical plane, so that the transmission box 4 is installed on the sling; operate the lifting equipment to move the transmission box 4 to the designated position.

[0029] The transmission box hoisting sling of the present invention solves the technical problem that the transmission box 11 cannot be hoisted, greatly improves the transportation and assembly efficiency of the transmission box 11, and greatly reduces safety hazards.

[0030] The weights on both sides of the connection point between the sleeve 42 and the second limiting groove 61 are not equal, and the center of gravity of the transmission box 4 is not at the connection point between the sleeve 42 and the second limiting groove 61. In order to keep the transmission box 4 balanced during transportation, the first support plate 5 and the second support plate 6 are located on the same side of the vertical plane where the connecting structure is located. In this way, the connecting structure is located above the heavier side, and the center of gravity of the connecting structure and the transmission box 4 are on the same vertical plane or as close to the same vertical plane as possible, ensuring that the transmission box 4 remains balanced during transportation.

[0031] In order to meet the transportation requirements of different transmission boxes 4 , two second limiting grooves 61 are provided on the second support plate 6 .

[0032] The connection structure comprises a lifting hole 81, to which the lifting hook of the lifting equipment connects. Furthermore, the connection structure includes multiple horizontally arranged lifting holes 81 to meet the handling requirements of different transmission boxes 4. In the illustrated embodiment, a hanging plate 8 is fixed to the hanging rod 1, and the hanging plate 8 is provided with three horizontally arranged lifting holes 81. In other embodiments, the lifting holes 81 can be provided directly on the hanging rod 1.

[0033] In order to facilitate installation of the first support plate 5 and the second support plate 6, the load bearing rod 3 is fixed with a connecting plate 7, and the first support plate 5 and the second support plate 6 are fixed on the connecting plate 7.

[0034] In order to strengthen the structural strength of the lifting tool, the reinforcing plate 9 is fixed between the lifting rod 1 and the connecting rod 2, and the inclined rib 10 is fixed between the connecting rod 2 and the load bearing rod 3.

[0035] The above is an example of the best embodiment of the present application, wherein the parts not described in detail are the common knowledge of those skilled in the art. The protection scope of the present application is subject to the content of the claims, and any equivalent transformation based on the technical inspiration of the present application is also within the protection scope of the present application.
