Description

Technical Field

[0001] The present invention relates to the field of rail transit vehicles, and particularly to an installation structure for end equipment of a bogie and a bogie. Background Art

[0002] To ensure the safe operation of rail vehicles and clear small obstacles on the track, a sweeper device is generally installed at the end of the bogie; to increase the adhesion between the wheel and the rail and prevent wheel sliding, a sanding device is generally installed at the end of the bogie. The heights of the sweeper and the sanding device from the rail surface need to meet the clearance requirements of the vehicle. As the wheels wear, the heights of the sweeper and the sanding device from the rail surface change. When the heights from the rail surface do not meet the clearance requirements, the heights of the sweeper and the sanding device need to be adjusted. Currently, the sweeper and the sanding device are usually installed on both sides of the end of the bogie through brackets. When adjusting the height, they need to be adjusted separately, and during the adjustment, the height needs to be measured while adjusting, which is troublesome and inconvenient to operate.

[0003] The installation brackets for the sweeper and the sanding device of the rail vehicle bogie are generally located at the end of the bogie frame. During the operation of the vehicle, they need to withstand lateral, longitudinal, and vertical vibration loads all the time, and the vibration loads at the end of the frame are relatively large. The bolt connection between the above-mentioned installation bracket and the frame is generally a group of bolts in one direction. For example, if the axial direction of the bolt is vertical, the lateral and longitudinal loads are superimposed to form the tangential load of the bolt. The greater the tangential load, the lower the anti-slip safety factor of the bolt connection, which is likely to cause the bolt to loosen and fail.

[0004] In addition to the sweeper and the sanding device, a wheel flange lubrication device, an antenna device, an obstacle detection device, etc. are usually installed at the end of the rail vehicle bogie. These devices are respectively installed at the end of the bogie through installation brackets, making the installation space at the end of the bogie compact and the layout tight, with great design difficulty. Summary of the Invention

[0005] The technical problem to be solved by the present invention is that, aiming at the inconvenience of height adjustment of the sweeper and the sanding device on the existing rail vehicle, the present invention provides an installation structure for end equipment of a bogie and a bogie that can quickly adjust the heights of all the sweepers and sanding devices on the bogie at the same time. To solve the above technical problem, the present invention adopts the following technical solutions:

[0006] An installation structure for end equipment of a bogie, including an end installation cross beam located below the end of the frame, and a sweeper plate is installed on the end installation cross beam. Its structural features are as follows:

[0007] End installation seats are respectively and fixedly installed on both sides of the end of the frame. The end installation seat includes a first connecting plate and a first sleeve fixedly connected below the first connecting plate. A plurality of first long strip holes are arranged vertically along the bogie on the first sleeve;

[0008] Both ends of the end mounting crossbeam are respectively provided with second sleeves. A first connection hole is provided on the second sleeve corresponding to the first long strip hole. The first sleeve and the second sleeve are installed with a clearance fit and are tightly connected by a first bolt passing through the first long strip hole and the first connection hole;

[0009] Both ends of the end mounting crossbeam are also respectively provided with second connection plates. The second connection plates and the first connection plates are tightly connected by a combination of articulated bolts;

[0010] The combination of articulated bolts includes a plurality of articulated bolts arranged vertically along the bogie. One end of the articulated bolt is tightly connected to the second connection plate, and the other end passes through the first connection plate and is respectively detachably tightened on the upper surface and the lower surface of the first connection plate.

[0011] In the present invention, an end mounting crossbeam is provided at the end of the bogie frame, and end devices such as a scraping plate (scraper) are installed on the end mounting crossbeam. After loosening the first bolt of the first and second sleeves for connection, by adjusting the effective connection length of each articulated bolt connecting the first and second connection plates, the installation height of the end mounting crossbeam can be adjusted, and then the height from the rail surface of all end devices on the end mounting crossbeam, including the scraper, sand spreading device, etc., can be quickly adjusted at one time.

[0012] Further, a height adjustment plate is installed on the scraping plate. When the vehicle is running normally, the bottom of the scraping plate is flush with the bottom of the height adjustment plate. When adjusting the height of the scraping plate from the rail surface, the bottom of the height adjustment plate protrudes from the bottom of the scraping plate as a height adjustment scale. In this way, during the height adjustment process, the length by which the bottom of the height adjustment plate protrudes downward from the scraping plate can be used as a scale to determine the height of the scraping plate from the rail surface, thus avoiding the inconvenience of measuring the height while adjusting the height of the scraping plate in the prior art and making its height adjustment operation simple, convenient and fast.

[0013] Further, a second connection hole is longitudinally provided on the second connection plate along the bogie. A connection ring is provided at the end of the articulated bolt, and the connection ring and the second connection hole are tightly connected by a second bolt. In this way, the second bolt can further bear the longitudinal load of the bogie, improve the longitudinal vibration resistance of the end device installation structure, and improve the installation stability of the end device.

[0014] Further, the first long strip holes are respectively arranged on the front, rear, left, and right sides of the first sleeve, and the first bolts passing through the first long strip holes on the front and rear sides of the first sleeve are arranged along the longitudinal direction of the bogie, and the first bolts passing through the first long strip holes on the left and right sides of the first sleeve are arranged along the transverse direction of the bogie. In this way, the present invention can bear longitudinal loads through the first bolts passing through the first long strip holes on the front and rear sides of the first sleeve, bear transverse loads through the first bolts passing through the first long strip holes on the left and right sides of the first sleeve, and together with the vertical loads borne by the knuckle bolts, thus significantly reducing the risk of loosening of the connecting bolts of the end mounting structure and ensuring the stability of the end mounting structure.

[0015] Further, the end mounting seats are symmetrically arranged on both sides of the longitudinal center plane of the bogie frame.

[0016] Further, the first sleeve and the second sleeve are square structures.

[0017] Further, a cleaning plate mounting seat, a sanding device mounting seat, and a lubrication device mounting seat are symmetrically arranged on the end mounting cross beam with respect to the longitudinal center plane of the bogie.

[0018] Based on the same inventive concept, the present invention also provides a bogie, on which the bogie end equipment mounting structure is provided. The cleaning plate, the sanding device, the wheel flange lubrication device, and the antenna device are integrally mounted on the end mounting cross beam, and the cleaning plate and the antenna device are mounted at the front end of the bogie and share the cleaning plate mounting seat.

[0019] Further, other mounting seats can also be arranged on the end mounting cross beam for mounting an obstacle detection device, an ATB antenna device, etc.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1) By mounting all the cleaning plates on the bogie on the end mounting cross beam, when it is necessary to adjust the height of the cleaning plate from the rail surface, only the height of the end mounting cross beam needs to be adjusted through the knuckle bolts and the first bolts. During the height adjustment process, the height adjustment is ensured to be in place through the height adjustment plate, and the height adjustment of the end equipment such as the cleaning plate can be quickly and conveniently carried out. The operation is simple and convenient, greatly saving the time and labor costs for the maintenance and repair of the bogie.

[0022] 2) In the connection between the end mounting seat on the bogie frame of the present invention and the end mounting crossbeam, bolt connections that are axially aligned with the lateral, longitudinal, and vertical directions of the bogie are arranged simultaneously. That is, through 4 first bolts axially aligned with the lateral direction of the bogie, the lateral connection between the end equipment mounting structure and the bogie in the lateral direction of the bogie is achieved; through 4 first bolts axially aligned with the longitudinal direction of the bogie, the longitudinal connection between the end equipment mounting structure and the bogie in the longitudinal direction of the bogie is achieved; and through 8 articulated bolts axially aligned with the vertical direction of the bogie, the connection between the end equipment mounting structure and the bogie in the vertical direction of the bogie is achieved, so as to respectively bear the vibration loads in the lateral, longitudinal, and vertical directions, greatly reducing the risk of failure and loosening of the mounting bolts of the frame end structure.

[0023] 3) Various mounting seats are provided on the end mounting crossbeam of the frame of the present invention, realizing the centralized installation of the sweeper device (sweeping stone slab), sanding device, wheel flange lubrication device, and antenna device, simplifying the end mounting bracket of the bogie, solving the problem of tight layout at the end of the bogie, and saving the installation space for end equipment.

[0024] 4) During the maintenance of the operation of rail vehicles, there are limit requirements for the height from the rail surface or the distance from the wheel tread surface for the sweeper device, sanding device, wheel flange lubrication device, and antenna device, and continuous inspection and adjustment are required. The present invention integrates the sweeper device, sanding device, wheel flange lubrication device, and antenna device on the end mounting crossbeam of the frame, and can quickly adjust the height of each end equipment at one time by adjusting the installation height of the end mounting crossbeam of the frame, and can be adjusted in place all at once, without the need to adjust each end equipment separately, saving the time and labor for maintenance, and the operation is simple.

[0025] 5) In addition to playing the role of quickly adjusting the height of the sweeping stone slab from the rail surface, the articulated bolt connection combination of the present invention also plays the role of connecting the end mounting seat and the end mounting crossbeam of the frame in the vertical direction and bearing the vertical load.

[0048] The end mounting seats 1 are symmetrically and fixedly installed on both sides of the end of the frame 11 with respect to the longitudinal center plane of the bogie. The end mounting seat 1 includes a first connecting plate 1.1 and a first sleeve 1.2 fixedly connected below the first connecting plate 1.1. A plurality of first elongated holes 1.3 are arranged vertically along the bogie on the first sleeve 1.2.

[0049] The end mounting crossbeam 3 is installed below the end crossbeam of the frame 11. Second sleeves 3.1 are respectively provided at both ends of the end mounting crossbeam 3. First connection holes 3.2 corresponding to the first elongated holes 1.3 are provided on the second sleeves 3.1. The first sleeve 1.2 is sleeved on the second sleeve 3.1 and forms a clearance fit with the second sleeve 3.1. The first elongated holes 1.3 and the first connection holes 3.2 are arranged corresponding to each other, and are tightly connected by the first bolt 2 passing through the first elongated holes 1.3 and the first connection holes 3.2.

[0050] Second connecting plates 3.8 are also respectively provided at both ends of the end mounting crossbeam 3. The second connecting plates 3.8 are arranged opposite to the first connecting plates 1.1 and are tightly connected into one body by the knuckle bolt connection assembly 4.

[0051] The articulated bolt connection assembly 4 includes a plurality of articulated bolts 4.1 arranged vertically along the bogie. One end of the articulated bolt 4.1 is provided with a connection ring 4.4. A second connection hole 3.9 is arranged longitudinally along the bogie on the second connecting plate 3.8. A second bolt 7 is installed in the second connection hole 3.9. The connection ring 4.4 is sleeved on the second bolt 7. The other end of the articulated bolt 4.1 passes through the first connecting plate 1.1, and is tightly connected on the upper surface and the lower surface of the first connecting plate 1.1 by a nut 4.2 and a gasket 4.3 respectively. Please refer to Figure 4 , Figure 5 and Figure 1 .

[0052] In this way, the end mounting crossbeam 3 is connected to the end mounting seat 1 through the articulated bolt connection assembly 4, the second bolt 7, and the first bolt 2. Among them, there are 8 first bolts 2 (4 for transverse connection and 4 for longitudinal connection), which are used to bear the loads in the transverse and longitudinal directions. The articulated bolt connection assembly 4 includes 8 articulated bolts 4.1 connected vertically to bear the vertical load. At the same time, the cleaning plate 5 is installed at the lower part of the end mounting crossbeam 3 through fasteners, and the height adjusting plate 6 is installed on the cleaning plate 5 through fasteners.

[0053] The first sleeve 1.2 and the second sleeve 3.1 are preferably square structural body sleeves. The first long strip holes 1.3 are respectively arranged on the front, rear, left, and right of the square structural body sleeve. The first bolts 2 passing through the first long strip holes 1.3 on the front and rear of the first sleeve 1.2 are arranged longitudinally along the bogie, and the first bolts 2 passing through the first long strip holes 1.3 on the left and right of the first sleeve 1.2 are arranged transversely along the bogie.

[0054] As Figure 4 shown, a cleaning plate mounting seat 3.3, a sanding device mounting seat 3.4, and a lubricating device mounting seat 3.6 are further arranged on the end mounting crossbeam 3. And a second long strip hole 3.5 for adjusting the mounting height of the sanding device is arranged on the sanding device mounting seat 3.4, and a third long strip hole 3.7 for adjusting the mounting position of the wheel flange lubricating device is arranged on the lubricating device mounting seat 3.6.

[0055] The first, second, and third long strip holes involved in this article are preferably waist-shaped holes.

[0056] When the rail vehicle is running normally, as Figure 1 shown, the bottom of the cleaning plate 5 is flush-mounted with the bottom of the height adjusting plate 6, which is convenient for the operation of the rail vehicle.

[0057] When it is necessary to adjust the height of the cleaning plate 5 from the rail surface, as Figure 2As shown, when the height adjustment plate 6 moves downward so that its bottom protrudes from the sweeping stone plate 5, the height adjustment plate 6 can be directly used as a measuring scale. After loosening the first bolt 2, the effective action length of the articulated bolt connection assembly 4 is adjusted, so that the installation height of the end-mounted cross beam 3 can be adjusted, and then the height of the sweeping stone plate 5 from the rail surface can be quickly adjusted. The specific adjustment method is as follows: First, press Figure 2 Adjust the height adjustment plate 6 as shown, then loosen the 8 nuts 4.2 under the first connecting plate 1.1 on each articulated bolt 4.1 in each of the first bolts 2 and the articulated bolt connection assembly 4, and then tighten the 8 nuts 4.2 on each articulated bolt 4.1 in the articulated bolt connection assembly 4 above the first connecting plate 1.1. During this process, the end-mounted cross beam 3 slowly moves (rises) towards the frame 11 until the bottom of the height adjustment plate 6 just touches the rail surface (that is, the bottom of the height adjustment plate 6 is flush with the rail surface), and the height of the sweeping stone plate 5 from the rail surface is adjusted to meet the limit requirements. At this time, stop the height adjustment. Finally, tighten the 8 nuts 4.2 under the first connecting plate 1.1 on each articulated bolt 4.1 in the articulated bolt connection assembly 4, and install the height adjustment plate 6 on the sweeping stone plate 5 as Figure 1 shown, and the height adjustment is completed.

[0058] As Figure 8 shown in (a) and (b) of, the frame end equipment installation structure of the present invention can integrally install the sweeping stone plate 5, the sand spraying device 9, the wheel flange lubrication device 10, and the antenna device 8 on the end-mounted cross beam 3. Both the sweeping stone plate 5 and the antenna device 8 are installed at the front end of the bogie and share the sweeping stone plate mounting seat 3.3. During the maintenance of the vehicle, the heights of the sweeping stone plate 5, the sand spraying device 9, the wheel flange lubrication device 10, and the antenna device 8 can be adjusted as a whole.

[0059] Other mounting seats can also be provided in the middle of the end-mounted cross beam 3 for mounting obstacle detection devices, ATB antenna devices, etc.
