[0059] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0060] The embodiment of the utility model provides a bracket for installing a wheel rim lubrication device and an obstacle monitoring device, such as Figure 1 and Figure 2 As shown, it includes an integrated bracket 1;

[0061] The integrated bracket 1 is used to be arranged at the end of the rail vehicle head axle bogie 4, and is used to integrate the wheel rim lubrication device 2 and the obstacle monitoring device 3 so that the wheel rim lubrication device 2 is in contact with the wheel rim of the rail vehicle head axle.

[0062] It should be noted that in the prior art, the wheel rim lubrication device 2 is installed on the bogie of the non-head axle of the rail vehicle through a bracket, which makes it difficult to maximize the effect of the wheel rim lubrication device 2, and considering the limited installation space at the end of the head axle bogie 4 of the rail vehicle; for this reason, the present scheme designs an integrated bracket 1 arranged (installed) at the end of the head axle bogie 4 of the rail vehicle, which is used for the integrated installation of the wheel rim lubrication device 2 and the obstacle monitoring device 3, and of course, the wheel rim lubrication device 2 will be in contact with the wheel rim of the head axle of the rail vehicle. In this way, the effect of the wheel rim lubrication device 2 can be maximized, that is, the effect of the wheel rim lubrication device 2 can be maximized, and the limited installation space at the end of the head axle bogie 4 can be taken into account, that is, the installation space of the bogie can be saved. Among them, such as Figure 1 As shown, the integrated bracket 1 is connected to the end of the head axle bogie 4 by bolts, the obstacle monitoring device 3 is connected to the integrated bracket 1 by bolts, and the wheel rim lubrication device 2 is connected to the integrated bracket 1 by bolts. Figure 1As shown, there are two integrated brackets 1, and each integrated bracket 1 is actually used to be arranged at the end of the bogie 4 on the head axle side of the rail vehicle, and is used to integrate and install one side of the wheel rim lubrication device 2 and the obstacle monitoring device 3. That is to say, this solution designs an integrated bracket 1 for integrating and installing the wheel rim lubrication device 2 and the obstacle monitoring device 3 at the end of the head axle bogie 4 of the rail vehicle, which can not only maximize the effect of the wheel rim lubrication device 2, but also take into account the limited installation space at the end of the head axle bogie 4, thereby better meeting the safety operation requirements of the rail vehicle.

[0063] It can be seen from the above technical solution that the bracket for installing the wheel rim lubrication device and the obstacle monitoring device provided in the embodiment of the utility model, by designing an integrated bracket for integrating the wheel rim lubrication device and the obstacle monitoring device at the end of the head axle bogie of the rail vehicle, can not only maximize the effect of the wheel rim lubrication device, but also take into account the limited installation space at the end of the head axle bogie, thereby better meeting the safety operation requirements of the rail vehicle.

[0064] In this scheme, if Figures 2 to 5 As shown, the integrated bracket 1 includes: a first bracket 11 and a second bracket 12;

[0065] The first bracket 11 is used to be arranged at the end of the head axle bogie 4 and is used to install the obstacle monitoring device 3; Figure 1 As shown, the first bracket 11 is actually used to install one side of the obstacle monitoring device 3;

[0066] The second bracket 12 is disposed on the first bracket 11 and is used to install the wheel rim lubricating device 2 so that the wheel rim lubricating device 2 contacts and cooperates with the wheel rim of the head shaft. Figure 1 and Figure 2 As shown, the first bracket 11 is connected to the end of the head axle bogie 4 by bolts, the obstacle monitoring device 3 is connected to the first bracket 11 by bolts, and the rim lubricating device 2 is connected to the second bracket 12 by bolts. In other words, the integrated bracket 1 adopts a split structure, which can facilitate the disassembly and assembly of the rim lubricating device 2, and also helps to reduce the cost of the integrated design of the integrated bracket 1. Of course, in the case where the manufacturing process meets the processing requirements, the integrated bracket 1 of this solution can also adopt an integrated structure, for example, an integrated integrated bracket 1 can be processed as a whole by CNC.

[0067] Specifically, Figure 6 and Figure 7 As shown, the first bracket 11 includes: a seat plate 111, a first rib plate 112, a first plate 113 and a second plate 114;

[0068] like Figure 1 As shown, the seat plate 111 is used to be arranged at the end of the head axle bogie 4;

[0069] The first plate 113 and the second plate 114 are arranged in parallel on the seat plate 111 and are bent downward respectively. The first plate 113 is located on the outer side of the second plate 114 and is used to install the obstacle monitoring device 3.

[0070] The first rib plate 112 is at least disposed between the first plate 113 and the second plate 114. Figure 4 As shown, the second bracket 12 is arranged on the first rib plate 112. The seat plate 111 is arranged at the end of the head axle bogie 4 in the vertical direction; Figure 6 As shown, the seat plate 111 is provided with four first bolt holes 1112, and is connected to the end of the head axle bogie 4 by bolts; the first plate 113 and the second plate 114 are respectively arranged vertically on the seat plate 111, the first plate 113 is located on the upper side of the second plate 114, and the two are respectively bent downwardly; that is, the first plate 113 and the second plate 114 are a group of parallel downwardly bent plates; wherein, as Figure 7 As shown, the first plate 113 and the second plate 114 each include: a bent plate portion (with an arc of 90°) and a vertical plate portion, wherein the horizontal end of the bent plate portion is connected to the seat plate 111, and the vertical end is connected to the vertical plate portion; the first rib plate 112 is at least adapted to be connected between the first plate 113 and the second plate 114, and its structure can be referred to Fig. 9 In short, the first bracket 11 is designed in such a way that the obstacle monitoring device 3 is vertically mounted on the first bracket 11 , and also helps to ensure the structural strength of the first bracket 11 .

[0071] Furthermore, if Figure 7 As shown, the lower part of the first plate 113 is a vertical plate (i.e., the vertical plate part described above); wherein, the upper part of the first plate 113 is a curved plate (i.e., the curved plate part described above); of course, the lower part of the second plate 114 is also a vertical plate, and the upper part is also a curved plate;

[0072] like Figure 6 As shown, the first bracket 11 also includes a first mounting seat 115, the structure of which can be referred to Figure 8 As shown;

[0073] The first mounting seat 115 is disposed on the vertical plate of the first plate 113 and is used to mount the obstacle monitoring device 3, so that the installation of the obstacle monitoring device 3 can be more stable and reliable. Figure 6As shown, the first mounting seat 115 is provided with four third bolt holes 1151, and is connected to the obstacle monitoring device 3 by bolts, and the four third bolt holes 1151 are waist-shaped holes (distributed along the vehicle width direction) that penetrate the first plate 113, ensuring that the obstacle monitoring device 3 has installation adjustment margin in the vehicle width direction. In addition, in order to meet the overall strength requirements of the first bracket 11, the first plate 113 and the second plate 114 are welded to the seat plate 111, the first rib plate 112 is welded between the first plate 113 and the second plate 114, and is also welded to the seat plate 111, and the first mounting seat 115 is welded to the vertical plate of the first plate 113. In other words, the first bracket 11 of this scheme, that is, the obstacle monitoring device mounting bracket, is welded by the seat plate 111, the first rib plate 112, the first plate 113, the second plate 114 and the first mounting seat 115, and all components can be made of steel plates, and all need to be painted for corrosion protection. Of course, the four third bolt holes 1151 on the first mounting seat 115 are processed after welding is completed.

[0074] Furthermore, if Figure 7 As shown, the seat plate 111 is provided with a stop 1111 for cooperating with the boss at the end of the head axle bogie 4, which can enable the seat plate 111 to be quickly installed and positioned at the end of the head axle bogie 4, and also can prevent the connecting bolts between the seat plate 111 and the end of the head axle bogie 4 from being subjected to shear force.

[0075] In this scheme, if Figure 7 As shown, the first rib plate 112 is provided with a limiting groove 1121; wherein the limiting groove 1121 can be a through limiting groove;

[0076] like Fig.17 As shown, the second bracket 12 is provided with a limiting protrusion 123 for cooperating with the limiting groove 1121 of the first rib plate 112. The limiting protrusion 123 of the second bracket 12 is used to be inserted into the limiting groove 1121 of the first rib plate 112, which not only enables the second bracket 12 to be limitedly installed on the first rib plate 112, but also prevents the connecting bolts of the second bracket 12 and the first rib plate 112 from being subjected to shear force.

[0077] Specifically, Fig.17 and Fig.18 As shown, the second bracket 12 includes: a second mounting seat 121 and a second rib plate 122;

[0078] The second mounting seat 121 is disposed on the first bracket 11 and is used to mount the wheel rim lubricating device 2 so that the wheel rim lubricating device 2 contacts and cooperates with the wheel rim of the head shaft;

[0079] The second rib 122 is disposed on the second mounting seat 121 .

[0080] It should be noted that if Figure 4As shown, the second mounting seat 121 is actually disposed on the first rib plate 112; Figure 7 As shown, the first rib plate 112 is provided with three second bolt holes 1122 and is connected to the second mounting seat 121 by bolts; in addition, in order to meet the overall strength requirements of the second bracket 12, the second rib plate 122 is welded to the second mounting seat 121. In other words, the second bracket 12 of this solution is welded by the second mounting seat 121 and the second rib plate 122, and these two components can be made of steel plates and both need to be painted for corrosion protection. In addition, as Figure 1 As shown, the second mounting seat 121 is used to mount the wheel rim lubrication device 2, and it is also necessary to ensure that the rear end of the wheel rim lubrication device 2 is not blocked by the obstacle monitoring device 3, so as to facilitate the replacement of the lubrication block of the wheel rim lubrication device 2 at a later stage. At the same time, it is also necessary to ensure that the relative position and angle between the wheel rim lubrication device 2 and the wheel rim are within a certain range.

[0081] Furthermore, if Figure 1 As shown, the second mounting seat 121 is distributed obliquely downward and toward the wheel rim of the head shaft, so that the wheel rim lubricating device 2 mounted on the second mounting seat 121 forms an angle with the plane where the head shaft is located. In this way, the rear end of the wheel rim lubricating device 2 can be directed toward the front and upward to prevent the rear end of the wheel rim lubricating device 2 from being blocked by the obstacle monitoring device 3. In other words, Figure 1 As shown, the obstacle monitoring device 3 is installed at the lower part of the integrated bracket 1, and the wheel rim lubrication device 2 is installed at the middle part of the integrated bracket 1, and its tail is facing forward and upward to avoid being blocked.

[0082] Furthermore, if Figure 23 to Figure 26 As shown, the second mounting seat 121 includes an L-shaped mounting seat; wherein the L-shaped mounting seat has a short portion and a long portion; wherein the short portion of the L-shaped mounting seat can be Fig.26 The vertical part of the middle L-shaped mounting base can be Fig.26 The horizontal portion of the middle L-shaped mount;

[0083] The short part of the L-shaped mounting seat is arranged on the first bracket 11, and the long part is distributed obliquely downward and toward the wheel rim of the head shaft, and is used to install the wheel rim lubricating device 2;

[0084] The second rib plate 122 is disposed between the short portion and the long portion of the L-shaped mounting seat. Figure 4 As shown, the short portion of the L-shaped mounting seat is connected to the first rib plate 112 by bolts, as shown in FIG. Fig.24As shown, the long portion of the L-shaped mounting seat includes a first long portion and a second long portion, the first long portion is vertically connected to the short portion of the L-shaped mounting seat, and the second long portion is connected to the first long portion and forms an angle, that is, the second long portion is distributed obliquely downward and faces the wheel rim of the head axis, and is used to install the rim lubrication device 2; wherein, the second long portion is provided with two fifth bolt holes 1212 (waist-shaped holes), and the rim lubrication device 2 is connected by bolts, so as to allow the rim lubrication device 2 to have installation adjustment margin along the radial direction of the wheel, that is, after the wheel is turned and repaired, the relative position and angle between the rim lubrication device 2 and the wheel rim are slightly adjusted to meet the functional requirements. In simple terms, two oblong holes (fifth bolt holes 1212) are provided side by side at a certain angle on the second long portion of the L-shaped mounting seat to meet the angle requirement of the rim lubrication device 2 relative to the wheel. At the same time, after the wheel is worn, the mounting bolts are adjusted to ensure that the rim lubrication device 2 can reliably contact and lubricate the wheel rim during the entire life cycle of the wheel. In addition, as Fig.18 As shown, the direction of the second rib plate 122 matches the direction of the long part of the L-shaped mounting seat, and the second rib plate 122 is welded between the short part and the long part of the L-shaped mounting seat, and the second rib plate 122 is provided with the above-mentioned limiting protrusion 123, and is inserted into the limiting groove 1121 of the first rib plate 112 after passing through the short part of the L-shaped mounting seat. Accordingly, as shown in FIG. Fig.25 As shown, a through slot 1213 for the limiting protrusion 123 of the second rib plate 122 to pass through is formed at the short portion of the L-shaped mounting seat.

[0085] It can be seen that the present solution provides a bracket for the integrated installation of a wheel rim lubrication device and an obstacle monitoring device, which has the characteristics of simple structure, small space occupation and low cost.

[0086] In addition, the production and assembly process of the bracket for installing the wheel rim lubrication device and the obstacle monitoring device provided by this solution is as follows:
