[0026] Example:

[0027] This embodiment provides an installation tool for a series of elastic nodes of a subway train bogie. The installation process is as follows: Figure 1 The bogie 1 of the subway train includes a cantilever 11, and the primary elastic node to be installed includes a split axial swing arm 12 and a primary steel spring assembly 13 located at the first end 121 of the split axle box swing arm 12. The primary steel spring assembly 13 is located between the cantilever 11 and the split axial swing arm 12.

[0028] like Figure 2 As shown, the installation tool 2 includes a main frame 21, a hydraulic cylinder 22, a pressure plate 23, a hydraulic pump station 24, a series of elastic node seat plates 25, an electric control box 26 of the hydraulic pump station, a wireless remote control handle 27 and a lifting ring 28.

[0029] The main frame 21 includes an upper frame 211, a lower frame 212, a first support column 213, and a second support column 214. A lifting ring 28 is symmetrically mounted on the upper surface of the upper frame 211. The first support column 213 and the second support column 214 are symmetrically arranged, with the top ends of both support columns fixedly connected to the upper frame 211 and the bottom ends of both support columns fixedly connected to the lower frame 212. The lower frame 212 includes a base frame 2121, a base plate 2122 fixedly connected to the base frame 2121, and a plurality of universal wheels 2123 disposed on the outer ends of the base frame 2121. The base frame 2121 is fixedly connected to the bottom ends of the first support column 213 and the second support column 214. The hydraulic pump station 24 is fixedly connected to the base frame 2121 and is located on one side of the first support column 213. The center of the base plate 2122 is aligned with the center of the primary elastic node seat plate 25 and the center of the pressure plate 23 on a vertical line. The primary elastic node seat plate 25 is fixedly connected to the base plate 2122.

[0030] The hydraulic cylinder 22 passes through the upper frame 211, and its end near the lower frame 212 is fixedly connected to the pressure plate 23 and connected to the hydraulic cylinder 22 by a pipe. A screw hole is provided on the top of the primary elastic node seat plate 25, and a screw is provided on the first end 121, threading the primary elastic node seat plate 25 to the first end 121. This structure can shift the center of force of the primary elastic node from the middle of the split axial swing arm 12 to the center of the primary elastic node seat plate 25, ensuring the balance of the primary elastic node. The hydraulic pump station electrical control box 26 is used to control the startup and operation of the hydraulic pump station 24. The wireless remote control handle 27 is communicatively connected to the hydraulic pump station electrical control box 26 and can be removably mounted on one side of the hydraulic pump station electrical control box 26. In other embodiments, the primary elastic node seat plate 25 is provided with a groove, which engages with the first end 121 during installation, further improving the stability of the primary elastic node during installation.

[0031] The installation tool 2 provided in this embodiment adopts a hydraulic transmission system as the power and actuator. The hydraulic transmission system includes a hydraulic cylinder 22, a hydraulic pump station 24 and a matching control system, namely a hydraulic pump station electric control box 26. The operation of the tool is controlled by a wireless remote control handle 27, which can reduce the tedious operation of the operator; the overall frame structure makes the entire tool more balanced in the hand, meeting the force requirements of the components during the installation process; the universal wheels 2123 equipped with the tool also greatly meet the flexibility of the tool. The entire set of installation tool 2 greatly facilitates the operation of on-site operators when installing a series of elastic nodes and improves work efficiency. Its working principle is specifically as follows:

[0032] Based on the hydraulic transmission system, when the tooling is pushed to the appropriate position, the tooling is started by controlling the wireless remote control handle 27, and the electric motor in the hydraulic pump station 24 drives the hydraulic oil to increase the pressure, and the high-pressure hydraulic oil is transmitted to the execution hydraulic cylinder 22 through the pipeline, thereby realizing the up and down movement of the pressure plate 23 on the hydraulic cylinder 22; through the force exerted by the hydraulic cylinder 22, a series of elastic nodes in the main frame 21 can be installed into the appropriate position.

[0033] Compared to previous installation equipment, the Installation Tool 2 offers advantages such as lower energy consumption, lower noise levels, and easier operation, significantly improving the work environment. Its simple and intuitive operation allows operators to quickly master the tool, and the tool is equipped with multiple safety mechanisms to ensure operator safety. Its simple design makes routine maintenance easy, significantly reducing worker workload and improving work efficiency.

[0034] Combine Figure 1 From the above, the specific operation process of the above-mentioned installation tool 2 in actual application is as follows:

[0035] 1) Push the installation tool 2 to the position where the primary elastic node is installed on the bogie 1, so that the primary elastic node is just below the installation position of the bogie 1. At this time, the cantilever 11 at the installation position of the bogie 1 passes through the middle space of the main frame 21 and is located between the pressure plate 23 and the primary steel spring assembly 13. The primary steel spring assembly 13 is located on the first end 121 of the split axial rotating arm 12. The first end 121 is placed on the primary elastic node seat plate 25, and the two are threadedly connected so that the installation point of the cantilever 11, the center of the pressure plate 23, the center of the primary steel spring assembly 13, and the center of the first end 121 are located on the same vertical line. This can keep the primary elastic node balanced and the force more evenly distributed.

[0036] 2) Press the pressure switch on the wireless remote control handle 27 to push out the hydraulic cylinder 22, driving the pressure plate 23 to move downward. After the pressure plate 23 presses against the upper surface of the cantilever 11, it will continue to push out, causing the entire main frame 21 to move upward, thereby causing a series of elastic nodes on the main frame 21 to move together;

[0037] 3) After reaching the installation position, the main frame 21 continues to move upward to compress the primary spring assembly 13 in the primary elastic node, so that the compression amount of the primary spring assembly 13 meets the installation requirements;

[0038] 4) After the installation requirements are met, install the fixing bolts and fixing pins;

[0039] 5) After the installation is completed, press the pressure relief switch on the wireless remote control handle 27, the hydraulic cylinder 22 begins to shrink, and after the main frame 21 lands, the hydraulic pump station 24 is closed and the installation tool 2 is pushed away from the station.

[0040] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology should be within the scope of protection defined by the claims.
