[0022] This utility model relates to a coupler disassembly and assembly anti-tipping lifting fixture, used in the disassembly and assembly of APM vehicle couplers to lift the coupler. The coupler has a transversely arranged crossbeam and a longitudinally arranged coupler rod. The fixture includes: a lifting frame, the bottom of which has a connection structure that cooperates with a lifting platform; a coupler head fixing bracket with a limiting notch, which is set on the top of the lifting frame to lift and fix the coupler rod; and two support plates, symmetrically arranged on the top of the lifting frame, to jointly support the bottom of the crossbeam.

[0023] Figure 1 The following are three views of the anti-tipping and lifting fixture structure for coupler disassembly and assembly according to an embodiment of the present utility model. (Refer to the following text.) Figure 1 The anti-tipping and lifting tool for assembling and disassembling the coupler according to an embodiment of the present utility model is described in detail.

[0024] The anti-tipping lifting fixture for coupler assembly and disassembly according to this utility model includes a lifting frame 101, a coupler head fixing bracket 102, and two support plates 103.

[0025] The lifting frame 101 constitutes the basic support structure of the tooling, and its bottom is provided with a connection structure (not shown in the figure) that mates with the lifting platform. This connection structure can adopt a boss-groove fit; for example, the connection structure is a boss, and the lifting platform has a groove that matches the boss; or the connection structure is a groove, and the lifting platform has a boss that matches the groove. This fit allows for quick positioning and prevents the tooling from shifting during lifting. The bottom of the lifting frame 101 is preferably rectangular to provide a stable support base.

[0026] In this embodiment of the invention, the lifting machine is a fixed or mobile device that uses mechanical, hydraulic, or pneumatic principles to safely and smoothly raise and lower heavy objects vertically. It is widely used in fields such as automotive repair and factory assembly to lift vehicles, machinery, or heavy goods for maintenance, installation, or handling operations. It comes in various forms, such as scissor lifts, pole lifts, and platform lifts.

[0027] A coupler head fixing bracket 102 is disposed on the top of the lifting frame 101 for supporting and fixing the coupler rod. The coupler head fixing bracket 102 includes a mounting plate 1021 and a lifting part 1022. The mounting plate 1021 is disposed at the bottom of the lifting part 1022 for fixed installation on the top of the lifting frame 101; the lifting part 1022 is provided with a V-shaped limiting notch 1023, and when the coupler rod is placed in the limiting notch 1023, the coupler rod is constrained in at least one direction (such as laterally).

[0028] In embodiments of this utility model, the mounting plate 1021 and the lifting part 1022 can be integrally formed to ensure structural strength; or the mounting plate 1021 and the lifting part 1022 can be connected by bolts, facilitating disassembly or replacement of the lifting part 1022, thereby improving the adaptability and maintenance convenience of the tooling. The limiting notch 1023 is designed as a V-shape, and in some other embodiments, it can also be designed as a U-shape. The inner surface of the limiting notch 1023 is embedded or covered with a soft anti-collision material to protect the surface of the coupler and prevent scratches.

[0029] Two support plates 103 are symmetrically arranged on the top of the lifting frame 101 to jointly support the bottom of the coupler beam. The surfaces of both support plates 103 are machined with anti-slip textures and covered with a soft, impact-resistant material to increase friction and protect the coupler surface equipment from scratches.

[0030] Furthermore, since the coupler installation requires high precision and accurate control of the coupler's spatial position and angle is necessary for successful completion, the top of the lifting frame 101 is also provided with a shim filling area (not shown in the figure). The shim filling area is provided with a shim limiting groove, the width of which is adapted to the width of the spare shim, and is used to adjust the installation angle of the coupler by adding or removing shims.

[0031] In embodiments of this utility model, the gasket limiting groove can be designed as multiple parallel rectangular grooves, which facilitates quick selection and adjustment of the gasket on site.

[0032] In use, first position and fix the tooling on the lifting platform. Operate the lifting platform to raise the tooling, guiding the coupler rod to the limiting notch 1023 of the coupler head fixing bracket 102 for limiting, while the coupler crossbeam is firmly supported by two support plates 103. Depending on the on-site alignment requirements, shims of different thicknesses can be inserted into the shim limiting grooves to finely adjust the coupler's pitch angle, ultimately completing the coupler assembly and disassembly operations safely and accurately.

[0033] In this embodiment of the invention, the anti-tipping lifting fixture for coupler assembly and disassembly is made entirely of high-strength low-alloy steel, ensuring sufficient strength and rigidity to withstand the weight of the coupler and various loads during operation. The high-strength low-alloy steel can be Q550D or Q690D grade. This type of steel, based on ordinary carbon steel, incorporates trace alloying elements (such as niobium, vanadium, and titanium), achieving a yield strength of 550MPa or 690MPa or higher, far exceeding that of ordinary Q235 steel. It also maintains good weldability and formability, making it ideal for manufacturing heavy-duty tooling components.

[0034] In embodiments of this invention, the anti-collision soft material layer (5) can be made of one or more composite materials selected from polyurethane, nylon, ultra-high molecular weight polyethylene, rubber, or EVA foam (but not limited to). These materials have the characteristics of good elasticity, wear resistance, and oil resistance, and can effectively buffer impacts and prevent scratches on the surface of the coupler. For example, polyurethane has good wear resistance and tear resistance; rubber can provide excellent cushioning and anti-slip effects; and nylon has high mechanical strength and wear resistance. To enhance wear resistance, polyurethane or nylon materials are preferred; to obtain the best cushioning and anti-slip effects, rubber materials are preferred.

[0035] The anti-tipping and lifting fixture for coupler assembly / disassembly provided by this utility model has the following beneficial effects: By cooperating with the lifting frame 101 and the lifting machine, the mechanical lifting of the coupler is achieved, which greatly reduces labor intensity and safety hazards. Through the synergistic effect of the limiting notch 1023 of the coupler head fixing bracket 102 and the two support plates 103, stable support and effective restraint of the coupler rod and crossbeam are achieved, significantly reducing the risk of overturning. The design of the shim filling area allows for fine-tuning of the coupler's installation angle, improving the accuracy and efficiency of disassembly and assembly. The use of impact-resistant soft materials protects the surface of expensive coupler equipment from damage; Made of high-strength low-alloy steel, the tooling is guaranteed to have structural reliability and long service life under heavy load conditions; The replaceable design of the lifting unit 1022 further enhances the applicability and maintainability of the tooling.

[0036] It will be understood by those skilled in the art that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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 make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
