Description

Technical Field

[0001] This utility model belongs to the field of special vehicle assembly technology, specifically relating to a special vehicle transmission box assembly hanger. Background Technology

[0002] In the assembly of special vehicles, the transmission box needs to be hoisted into the designated position inside the vehicle and aligned before assembly. In the past, general-purpose lifting tools or slings were used for assembly. However, the slings or chains lacked rigidity, and the transmission box's center of gravity was not centered during hoisting, resulting in an incorrect assembly posture. This required repeated manual adjustments during assembly, which was time-consuming, labor-intensive, inefficient, and posed safety hazards. Utility Model Content

[0007] Both the left and right hanger assemblies have a bent structure, and the lower half of the left and right hanger assemblies are machined with transmission box fixing holes for fitting onto the transmission box lugs;

[0008] The upper parts of the left and right hanger assemblies are arranged crosswise and connected by a rotating assembly. The top of the upper part is connected to a lifting lug by a lifting lug fixing pin and a cotter pin, respectively. Each lifting lug is connected to a chain, and the top of the two chains are connected to the same lifting ring, which is used to connect to the hook.

[0009] Furthermore, the left hanger assembly and the right hanger assembly are structurally symmetrical.

[0010] Furthermore, both the left hanger assembly and the right hanger assembly have a bending structure configured as an obtuse angle.

[0011] Furthermore, the lower half of the bent structure is set vertically when the transmission box is hoisted.

[0012] Furthermore, the rotating assembly includes a hanger assembly fixing pin and a cotter pin; wherein the pin passes through the through holes provided in the upper part of the left hanger assembly and the right hanger assembly, and the cotter pin is inserted into the front end of the hanger assembly fixing pin to fix the hanger assembly fixing pin.

[0013] Furthermore, a washer is provided on the inner side of the cotter pin and fitted onto the fixing pin of the hanger assembly to adjust the fixed position of the fixing pin of the hanger assembly and prevent lateral movement.

[0014] Furthermore, the left hanger assembly and the right hanger assembly are rigid structures.

[0015] (III) Beneficial Effects

[0016] This utility model proposes a special assembly hanger for a transmission box of a special vehicle, including a left hanger assembly, a right hanger assembly, a lifting lug, a chain, and a lifting ring. Both the left and right hanger assemblies have a bent structure. The lower half of the left and right hanger assemblies is machined with a transmission box fixing hole for fitting onto the transmission box support lug. The upper half of the left and right hanger assemblies are arranged crosswise and connected by a rotating assembly. The top of the upper half is connected to a lifting lug by a lifting lug fixing pin and a cotter pin, respectively. Each lifting lug is connected to a chain, and the top of the two chains are connected to the same lifting ring, which is used to connect to a hook.

[0017] When hoisting the transmission box, the fixing holes on the left and right hanger assemblies are used to fix the transmission box. The transmission box is then hoisted to the installation position for assembly using a hook. In this utility model, the left and right hanger assemblies are rigid hangers, which can effectively prevent the transmission box from tilting when hoisting. This improves the problem of unstable posture of the transmission box when using general lifting tools for assembly, increases assembly efficiency, and reduces assembly safety hazards. The lifting tools are simple to manufacture, easy to carry, easy to modify, highly compatible, and easy to operate. Attached Figure Description

[0022] To make the objectives, contents, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0023] This embodiment proposes a special assembly hanger for a transmission box of a special vehicle, the overall structure of which is as follows: Figure 1As shown, it mainly includes a left hanger assembly 1, a right hanger assembly 2, a lifting lug 3, a chain 4, and a lifting ring 5. Among them, the left hanger assembly 1 and the right hanger assembly 2 are symmetrical in structure and both have a bent structure with an obtuse angle. The lower half of the bent structure is set vertically when lifting the transmission box. The lower half of the left hanger assembly 1 and the right hanger assembly 2 are machined with transmission box fixing holes for fitting onto the transmission box lug.

[0024] The upper halves of the left hanger assembly 1 and the right hanger assembly 2 are cross-connected by a rotating assembly. The top ends of the upper halves are connected to a hanger 3 via a hanger fixing pin 9 and a cotter pin 7, respectively. Figure 2 As shown. Each lug 3 is connected to a chain 4, and the top ends of the two chains 4 are connected to the same lifting ring 5, which is used to connect to the hook.

[0025] like Figure 3 As shown, the rotating assembly includes a hanger assembly fixing pin 6, a cotter pin 7, and a washer 8. The hanger assembly fixing pin 6 passes through through holes in the upper parts of the left hanger assembly 1 and the right hanger assembly 2, and the cotter pin 7 is inserted into the front end of the hanger assembly fixing pin 6 to secure it. A washer 8 is fitted inside the cotter pin 7 and sleeved on the hanger assembly fixing pin 6 to adjust its fixed position and prevent lateral movement.

[0026] When lifting the transmission box, the transmission box fixing holes of the lower half of the left hanger assembly 1 and the right hanger assembly 2 are fitted onto the transmission box lugs. After adjustment, the transmission box is lifted to the installation position for assembly.
