Description

Technical Field

[0008]

[0001] The utility model relates to the field of rail transit, in particular to an installation tool for a gearbox hanger rod of a bogie. Background Technique

[0002] The lower part of the gearbox hanger rod 5 of the bogie is connected to the gearbox 7, and the upper part is connected to the frame 6. During the installation process, the space is limited, as Figure 1 shown.

[0003] For the assembly of the gearbox 7 of the bogie, it is necessary to first complete the assembly of the wheel set and axle box, then install the motor on the motor mounting seat, fix the gearbox hanger rod 5 on the base of the gearbox 7, and then fix the gearbox hanger rod 5 on the gearbox hanger seat of the frame 6, and connect the motor-side coupling and the gearbox 7-side coupling.

[0004] Use the AW0 load to simulate the vehicle load, measure the height difference of the coupling, and adjust the height difference of the coupling within the specified range by adding or subtracting the adjustment pads of the gearbox hanger seat. Then perform static pressure. After measuring that the height of the coupling is qualified, tighten the bolts.

[0005] During the construction process of the gearbox hanger rod 5, it is necessary to measure the height difference of the coupling under the static pressure load state, add or subtract the adjustment pads when the load is unloaded and then reinstall the gearbox hanger rod 5. This part is disassembled and reinstalled repeatedly during each construction until the height difference of the coupling meets the drawing dimensions. Since the gearbox 7 is an asymmetric structure, after the lower part of the gearbox hanger rod 5 is bolted to the gearbox 7, before the upper part of the gearbox hanger rod 5 is bolted to the gearbox hanger seat of the frame 6, it will tilt under the influence of gravity, resulting in inability to fix during installation and posing a risk of injuring people. Content of the Utility Model

[0006] The purpose of the utility model is to design an auxiliary installation tool, which can avoid repeatedly disassembling and reinstalling the gearbox hanger rod. By lifting the gearbox hanger rod during the installation of the gearbox hanger rod, it is possible to add or subtract the adjustment pads without removing the hanger rod, improving the installation work efficiency and construction safety of the bogie;

[0007] To achieve the above purpose, the utility model provides an installation tool for a gearbox hanger rod of a bogie, including a hoisting device, a lifting ring, a first rib plate and a second rib plate. The hoisting device is machined and produced from a whole steel plate, and the overall structure of the hoisting device is an unequal-sided "L" shape. There are threaded holes on the short side of the "L" shape of the hoisting device. The lifting ring is fixed on the threaded hole of the hoisting device by threads. The first rib plates are symmetrically welded at the right angle on the side of the hoisting device close to the short side, and the second rib plates are symmetrically welded at the end of the long side of the hoisting device.

[0008] Further, the second rib plate adopts a curved structure, which is integrally in a "U" shape, with an arc on the upper end surface and a semi-circular shape on the lower cross-section, to avoid displacement interference with the gearbox hanger rod.

[0009] Further, the upper end surface arc of the second rib plate is in contact connection with the nodes on both sides of the gearbox suspension rod. By using the lifting force of the overhead crane, the nodes of the gearbox suspension rods on both sides are pulled to lift the gearbox suspension rod, and the adjustment pad is installed.

[0010] The utility model solves the problem of repeatedly disassembling and assembling the bolts at the gearbox suspension rod part when adjusting the height difference of the coupling of the bogie, realizes adding and subtracting the adjustment pads of the gearbox suspension seat without disassembling the vehicle, improves the working efficiency and construction safety of the bogie suspension rod, and at the same time has the characteristics of being免于反复拆装, adding and subtracting adjustment pads, quickly lifting and lowering, protecting the paint on the surface of the gearbox suspension seat and the frame.

[0015] Referring to Figure 2 , the utility model is composed of components such as a lifting device 1, a lifting ring 2, a first rib plate 3, and a second rib plate 4. The lifting device 1 is machined and produced from a whole steel plate. The overall structure of the lifting device 1 is an unequal-sided "L" shape. Threaded holes are provided on the short side of the "L" shape of the lifting device​​​​​​​​​​

[0019] The installation process of this utility model in a specific embodiment is as follows: After measuring the height difference of the coupling under static pressure of the bogie, the bogie is pushed out of the static pressure station, the lower bolt of the gearbox lifting rod 5 is loosened, the upper bolt of the gearbox lifting rod 5 is removed, the lifting strap is inserted into the lifting ring 2, and this utility model is installed at the gearbox lifting rod 5. The upper end arc of the second stiffener 4 contacts and connects with the nodes 8 on both sides of the gearbox lifting rod 5. Using the lifting force of the overhead crane, the gearbox lifting rod 5 is lifted by pulling the two sides of the gearbox lifting rod 5. The adjusting shim is installed, the utility model is removed, the upper bolt of the gearbox lifting rod 5 is installed, and the upper and lower bolts of the gearbox lifting rod 5 are tightened.

[0020] This utility model provides a fixture for installing the gearbox hanger rod of a bogie, which solves the problem of repeatedly disassembling and assembling the bolts at point 5 of the gearbox hanger rod when adjusting the height difference of the bogie coupling.
