Description

Technical Field

[0001] This utility model belongs to the field of locomotive bogie maintenance technology, and mainly relates to a process bogie support device for locomotives. Background Technology

[0002] Currently, during maintenance, HXD3C locomotives need to be transferred from the car body maintenance workshop to the paint shop via rail, and then transferred again to the assembly workshop via rail after painting. Because the width of the high-curvature spring boxes and the center distance between the spring boxes differ from those of the main model (HXD1 series), the existing process bogie support devices and methods cannot handle the task of transferring HXD3C locomotive bodies. This results in poor compatibility and fails to meet the maintenance and transfer requirements of the HXD3C locomotive. During transfer, unsafe factors such as shaking and displacement are prone to occur, causing significant inconvenience to maintenance work and posing certain safety hazards. Therefore, there is an urgent need for a process bogie support device that can be adapted to the HXD3C locomotive to solve these problems. Utility Model Content

[0005] The adjusting component includes an adjusting bolt and a locking nut; the adjusting bolt is inverted and passes through a strip-shaped through hole on the support base, and the bolt head of the adjusting bolt is locked in a T-slot and can move within the slot.

[0006] The support column is a columnar structure, and a reinforcing rib plate is welded to its bottom circumference to enhance the stability of the support column; there are four reinforcing rib plates, which are arranged in a cross shape, with their inner surfaces welded to the outer circumference of the support column and their bottom surfaces welded to the top surface of the support base.

[0007] The support column is made of high-strength alloy steel and its surface is treated with anti-rust to ensure that it is not easily deformed or rusted during long-term use.

[0008] The support plate is made of thickened steel plate, and its area is designed according to actual needs to ensure sufficient support area.

[0014] The present invention will be described in conjunction with the accompanying drawings.

[0015] like Figures 1-2The diagram illustrates a bogie support device for locomotives, comprising a bogie support beam 1 mounted on the bogie; symmetrically arranged T-slots 2 are formed along the long side of the top surface of the support beam 1, and two identical support seats 3 are symmetrically arranged on the T-slots 2; each support seat 3 is rectangular, and multiple symmetrically arranged strip-shaped through holes 4 are formed along the T-slots 2; the strip-shaped through holes 4, in conjunction with adjusting bolts 8 and locking nuts 9, allow for precise adjustment of the support seat position and rapid locking, greatly improving adjustment efficiency and stability; vertically arranged support columns 5 are welded to the center of the top surface of each support seat 3; A support plate 6 is welded to the top surface of the support column 5. The support plate 6 is made of thickened steel plate, and its area is designed according to actual needs to ensure sufficient support area. The support plate 6 is a rectangular steel plate, and its size is customized according to the actual needs of the locomotive body to ensure sufficient support area. A vertically arranged positioning pin 7 is welded to the center of the top surface of the support plate 6. The positioning pin 7 adopts a cylindrical design, and its diameter and height are matched according to the positioning hole size of the locomotive body to ensure accurate positioning. The positioning pin 7 is precisely machined according to the positioning hole of the locomotive body to ensure that it can be accurately inserted into the positioning hole to achieve precise positioning of the process bogie and the locomotive body.

[0016] At the connection between the support base 3 and the T-slot 2, an adjusting component for adjusting the position of the support base 3 is also provided. The adjusting component includes an adjusting bolt 8 and a locking nut 9. The adjusting bolt 8 is inverted and passes through the strip-shaped through hole 4 on the support base 3, and the bolt head of the adjusting bolt 8 is engaged in the T-slot 2 and can move within the slot. This design allows for precise adjustment of the position of the support base 3 on the T-slot 2 by adjusting the bolt 8, to accommodate locomotive bodies of different sizes, thus improving the versatility and flexibility of the device. The locking nut 9 is threaded onto the rod of the adjusting bolt 8 that extends out of the strip-shaped through hole 4. By rotating the locking nut 9, the support base 3 and the T-slot 2 can be locked and fixed. When it is necessary to adjust the position of the support base 3, simply loosen the locking nut 9, push the support base 3, and move the bolt head of the adjusting bolt 8 within the T-slot 2. After the support base 3 has moved to the appropriate position, tighten the locking nut 9.

[0017] The support column 5 is a columnar structure, with reinforcing ribs 10 welded to its bottom circumference to enhance its stability. There are four reinforcing ribs 10 arranged in a cross shape, with their inner surfaces welded to the outer circumference of the support column 5 and their bottom surfaces welded to the top surface of the support base 3. These reinforcing ribs 10 effectively enhance the stability of the support column 5, preventing deformation or damage during use. The support column 5 is made of high-strength alloy steel with a rust-proof surface treatment, ensuring it is not easily deformed or rusted during long-term use. A full welding process is used when welding the top of the support column 5 to the support plate to ensure the strength and stability of the connection.

[0018] In use, this utility model first lifts and installs the support device onto the process bogie, and fixes it to the process bogie via the support beam 1. Then, according to the actual size of the locomotive body, the position of the support seat 3 is precisely adjusted by adjusting the components. Specifically, the locking nut 9 is loosened, the support seat 3 is pushed, and the bolt head of the adjusting bolt 8 moves within the T-slot 2. After the support seat 3 moves to a suitable position that matches the size of the locomotive body, the locking nut 9 is tightened to lock the support seat 3 and the T-slot 2. Then, with the cooperation of the overhead crane, the car body is lifted to directly above the two process bogies, so that the support column 5 is inserted into the secondary spring box. The position of the car body is adjusted so that the positioning pin 7 is inserted into the center hole of the secondary spring box. After the shunting locomotive connects to the process bogie coupler, the precise positioning of the process bogie and the locomotive body is achieved. The car body can then be transferred between different areas via the track, meeting the maintenance and transfer needs of the HXD3C locomotive.
