[0020] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments;

[0021] Figure 1 It is a structural diagram of the present utility model. DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] Reference Figure 1 This specific embodiment adopts the following technical solution: a painting and transfer tool for urban rail vehicle bogie parts, including a walking dummy trolley 1, a transmission device 2 and a support assembly 3. The walking dummy trolley 1 is provided with a support assembly 3, and the support assembly 3 is installed with a transmission device 3. The transmission device 3 rotates with the axle box 4.

[0024] It is worth noting that the walking trolley 1 is arranged on both sides below the support assembly 3. The walking trolley 1 includes walking wheels 11, a wheel frame 12, a connecting plate 13 and a support rod 14. Walking wheels 11 are provided at both ends of the bottom of the wheel frame 12. The wheel frames 12 are connected by a connecting plate 13, and a support rod 14 is fixed above the middle of the connecting plate 13.

[0025] It is worth noting that the support assembly 3 includes two parallel support plates 31. The support plates 31 are fixed to the top of the support rod 14 of the walking trolley 1.

[0026] It is worth noting that the transmission device 2 includes a motor 21 and a turntable 22 . The motor shaft of the motor 21 is connected to the turntable 22 , and a plurality of axle boxes 4 are installed on the turntable 22 .

[0027] It is worth noting that the motor 21 is also connected to a driver.

[0028] It is worth noting that the running wheel 11 is a running wheel with a foot brake.

[0029] It is worth noting that both sides of the support rod 14 are supported on the connecting plate 13 by inclined rods 15, thereby increasing stability.

[0030] In addition, the transmission devices 2 are provided in plurality and are arranged at intervals.

[0031] The traveling dummy trolley in this embodiment supports the full weight of the transport tooling and features wheels for easy transport. The transmission is a rotatable device that provides rotational power for the sprayed workpiece, integrating a motor, turntable, and driver. The support assembly supports the sprayed workpiece and provides a fixed mechanism for rotation. The axlebox is a component of the vehicle bogie that requires sandblasting and spraying during repair. Example 1

[0032] This embodiment applies the above-mentioned urban rail vehicle bogie parts painting and transfer tooling to a certain subway, achieving the following effects:

[0033] 1. To meet the needs of transporting and spraying the bogie parts for the overhaul of Metro Line 3 and Line 4, the tooling has been used to complete the spraying of 60 train parts.

[0034] 2. Comparison with the original method: The original spraying process for a single train of 48 parts required manual handling and flipping during spraying, requiring an average of six days for each train and requiring at least four workers. This new tool eliminates the need for flipping, shortening the production cycle by three days and requiring only one operator. This significantly reduces production time and labor costs. The new tooling reduces the total production cycle by approximately 180 days, saving 540 man-days of labor costs.

[0035] 3. Each component weighs about 30 kilograms. Manual handling poses a safety hazard of injuring hands and feet, and bending over to carry it can easily cause muscle strain. With this tooling, you only need to use a sling to lift the tooling, avoiding operational safety hazards and reducing safety risks.

[0036] 4. The tooling is versatile and can be widely used in the maintenance projects of metro bogie parts on Line 3, Line 4, and subsequent Lines 5 / 8 / 9.

[0037] 5. The tooling has a simple structure and is made of the company's waste materials. It has low cost, is easy to repair and maintain, and has high practical and economic value.

[0038] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
