[0038] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0039] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0040] Secondly, it should be noted that in the description of the present application, terms such as "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings. This is only for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present application.

[0041] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0042] The medium and low speed maglev turnout is an important equipment to realize the switching of the maglev line, and the turnout trolley provides power for the movement of the turnout. Specifically, the turnout trolley moves along the trolley track, which can drive the turnout beam to rotate and realize the turnout switching function. As the turnout system operates for a long time, maintenance is required, such as regular lubrication and maintenance of the turnout trolley wheels and replacement of internal bearings.

[0043] However, the existing switch trolley structure is relatively bulky, and the switch trolley needs to be taken out from under the switch beam for maintenance, which makes the maintenance of the switch trolley difficult and requires a long period of time. The maintenance window period of the operating line is short, and it is difficult to complete all maintenance of the switch trolley within a maintenance window period, which may affect the safety of line operation.

[0044] In order to avoid the above-mentioned problems, the present application provides a turnout trolley wheel group structure and a turnout trolley. By changing the structure of the turnout trolley wheel group, the convenience of wheel and bearing maintenance can be improved, the maintenance time can be effectively shortened, and it helps to improve the safety of line operation.

[0045] The present application is described in detail below with reference to the accompanying drawings and specific embodiments:

[0046] See also Figure 1 , Figure 2 and Figure 7 As shown, this embodiment provides a turnout trolley wheel group structure 1, which is mainly used to assist the turnout trolley body to move so as to drive the turnout beam body to turn. It is installed on the crossbeam a of the turnout trolley. Specifically, the turnout trolley wheel group structure 1 of this embodiment includes a mounting bracket, a wheel axle 153, a wheel 151 and a bearing 157.

[0047] The mounting bracket includes a first bracket 12 and a second bracket 11, the first bracket 12 and the second bracket 11 are detachably connected, and the second bracket 11 is used to connect with the crossbeam a to realize the connection between the turnout trolley wheel group structure 1 and the trolley body. It is understandable that the second bracket 11 can be fixed on the trolley crossbeam a by bolts or other means, as long as it is ensured that the second bracket 11 and the crossbeam a will not be separated during the operation of the turnout trolley, and this embodiment does not limit it here. The wheel 151 is mounted on the wheel shaft 153, that is, a through hole is opened in the middle of the wheel 151 for the wheel shaft 153 to pass through, so as to realize the connection between the two, and at the same time, a mounting cavity 152 is provided on the wheel 151, and a bearing 157 is located in the mounting cavity 152, and the outer ring of the bearing 157 is connected to the wheel 151, and the inner ring of the bearing 157 is connected to the wheel shaft 153, so as to realize the rotation connection between the wheel 151 and the wheel shaft 153 through the bearing 157, that is, the wheel 151 can rotate relative to the wheel shaft 153. It can be understood that the bearing 157 is similar to the existing bearing structure, which includes an outer ring, an inner ring, rolling elements and a retaining frame. The rolling elements are located between the outer ring and the inner ring and can roll between the inner ring and the outer ring to reduce friction. The rolling elements can be common structures such as steel balls and rollers, and the retaining frame is used to fix the position of the rolling elements so that they are evenly distributed inside the bearing to ensure a stably connected wheel 151 and wheel axle 153. The wheel axle 153 is mounted on the first bracket 12 and is positioned and supported by the first bracket 12. Specifically, first slots 1531 are provided at both ends of the wheel axle 153. A first connecting member 156 is provided in the first slot 1531. The first connecting member 156 is detachably connected to the first bracket 12, that is, part of the first connecting member 156 is inserted into the first slot 1531, and part of it is connected to the first bracket 12. Since the first slots 1531 are provided at both ends of the wheel axle 153, after the first connecting member 156 is inserted into the first slot 1531 and connected to the first bracket 12, the axial position of the wheel axle 153 is restricted to prevent the wheel axle 153 from being separated from the first bracket 12.

[0048] Among them, one wheel axle 153 corresponds to one wheel 151, and the specific number of wheel axles 153 and wheels 151 used can be selected according to the load-bearing requirements of the turnout trolley, such as one, two or three, etc. Of course, when multiple are set, they need to be arranged side by side, and this embodiment does not limit this.

[0049] It is understandable that the positions of the first slot 1531 and the first connecting member 156 can be selected according to actual conditions, as long as the first bracket 12 and the wheel axle 153 can be effectively connected and the wheel axle 153 can be prevented from moving along its axial direction. This embodiment does not limit it.

[0050] Exemplarily, the first bracket 12 has a cavity for accommodating the wheel 151, and both ends of the wheel axle 153 extend to the outside of the cavity. The first slot 1531 is located at one end of the wheel axle 153 extending to the outside of the cavity. After the first connecting member 156 is inserted into the first slot 1531, the portion exposed in the first slot 1531 fits with the outer surface of the cavity. Subsequently, the first connecting member 156 and the first bracket 12 can be connected by bolts or other common methods. As long as the first connecting member 156 does not automatically detach from the first bracket 12, this embodiment is not limited thereto.

[0051] Exemplarily, the first slot 1531 and the first connector 156 may be located between the wheel 151 and the inner wall of the cavity.

[0052] When it is necessary to maintain and service components such as the wheel 151 and the bearing 157, the first bracket 12 can be directly removed from the second bracket 11, and the first bracket 12, wheel 151, wheel axle 153, and bearing 157 can be moved out from under the turnout beam as a whole. Compared with originally moving the entire turnout trolley out from under the turnout beam, this not only greatly reduces the weight, but also does not require the connection between the turnout trolley and the turnout beam to be released, which greatly reduces the difficulty of disassembly and installation. After the first bracket 12, wheel 151, wheel axle 153, and bearing 157 are moved out from under the turnout beam as a whole, the first connecting piece 156 can be directly removed to separate the first bracket 12 and the wheel axle 153. Subsequently, the wheel 151, bearing 157 and other components can be quickly maintained, which greatly reduces the difficulty of maintaining the turnout trolley and can effectively shorten the time required for maintenance of the turnout trolley.

[0053] For some possible implementations, see Figure 6 and Figure 7 As shown, a lubricating oil passage is provided on the wheel axle 153 , and an oil nozzle 154 connected to the lubricating oil passage is provided at at least one end of the wheel axle 153 . The lubricating oil passage is used to deliver the lubricating oil into the bearing 157 through the wheel axle 153 .

[0054] With this arrangement, when the bearing 157 needs to be lubricated, the lubricating oil can be directly injected into the bearing 157 through the oil nozzle 154 without removing the bearing 157, which further reduces the difficulty of maintenance and can also further shorten the maintenance cycle of the switch trolley.

[0055] Among them, in order to further improve the efficiency of maintenance, an oil nozzle 154 is respectively provided at both ends of the wheel axle 153, and the lubricating oil channel includes a first oil channel 1530 and at least one second oil channel 1532. The first oil channel 1530 connects the two oil nozzles 154, and one end of the second oil channel 1532 is connected to the first oil channel 1530, and the other end passes through the side wall of the wheel axle 153 and is connected to the inside of the bearing 157. It can be understood that when multiple second oil channels 1532 are provided, the second oil channels 1532 can be evenly arranged on the side wall of the wheel axle 153, so that the lubricating oil that reaches the second oil channel 1532 through the first oil channel 1530 can quickly enter the inside of the bearing 157 at multiple angles, thereby greatly improving the lubrication efficiency.

[0056] At the same time, lubricating oil can also be injected through the two oil nozzles 154 to further improve the injection efficiency of the lubricating oil and assist in improving the maintenance efficiency of the switch trolley.

[0057] It is understandable that one, two or more second oil passages 1532 may be provided, and the specific selection may be made according to the actual situation such as the size of the bearing 157 , and this embodiment does not limit this.

[0058] For some possible implementations, see Figure 7 As shown, at least one end of the installation cavity 152 is provided with an installation opening for the bearing 157 to enter and exit, and the wheel 151 is detachably connected with an end cover 155, so that the installation opening can be opened and closed through the end cover 155. Therefore, when the bearing 157 needs to be removed, the end cover 155 can be directly removed, and the position of the bearing 157 can also be limited by the end cover 155 to prevent the bearing 157 from axial displacement, that is, the end cover 155 can be used to stop the outer ring of the bearing 157, so that the bearing 157 cannot be axially displaced.

[0059] Furthermore, a mounting opening can be provided at each end of the mounting cavity 152, and an end cap 155 can be provided at each mounting opening, that is, the mounting cavity 152 is a through-hole-like structure, which can effectively reduce the weight of the wheel 151, and the wheel 151 does not need to be connected to the wheel shaft 153, and the wheel 151 is completely connected to the wheel shaft 153 through the bearing 157, which can effectively improve the smoothness of the rotation of the wheel 151. At the same time, the two ends of the outer ring of the bearing 157 are against the end caps 155 at the two ends of the mounting cavity 152, so that the bearing 157 cannot be axially displaced.

[0060] In addition, the end cap 155 can be fixed to the wheel 151 by bolts, such as Figure 7 As shown, a groove can be set at both ends of the wheel 151, and the edge of the end cover 155 is engaged in the groove, and then the bolts are inserted into the holes corresponding to the edge of the end cover 155 and the groove wall, which can effectively connect the end cover 155 to the wheel 151 and prevent the end cover 155 from protruding outside the wheel 151.

[0061] For some possible implementations, see Figure 4 , Figure 6 and Figure 7 As shown, the first bracket 12 includes at least two support members 15, the support members 15 are respectively located at both ends of the wheel shaft 153, and a cavity for mounting the wheel 151 is formed between the two support members 15, and the first connecting members 156 located at both ends of the wheel shaft 153 are respectively connected to the support members 15 closest to them, and both ends of the wheel shaft 153 are provided with shaft shoulders so that the support member 15 is clamped between the shaft shoulder and the first connecting member 156, that is, the outer diameter of the shaft shoulder is larger than the inner diameter of the hole on the support member 15 for the bearing 157 to pass through, and the support member 15 is close to the first connecting member 156. The end close to the wheel 151 is clamped on the shoulder of the shaft, and after the first connecting member 156 is inserted into the first clamping groove 1531, the surface of the first connecting member 156 close to the wheel 151 is fitted with the surface of the support member 15 away from the wheel 151, and then the first connecting member 156 and the support member 15 are locked by bolts or other common components to prevent the wheel shaft 153 from moving relative to the support member 15. In this way, there is no need to connect bolts or the like on the wheel shaft 153 to achieve the fixation of the wheel shaft 153, and the fixing and disassembly operations are extremely simple.

[0062] For further information, see Figure 2 , Figure 3 and Figure 4 As shown, two wheel axles 153 are arranged side by side, the first bracket 12 also includes a first connection portion 1201 extending between the two wheel axles 153, and two second connection portions 1202 extending above the two wheel axles 153 respectively, the support member 15 includes a third connection portion 1521 and a fourth connection portion 1520, the third connection portion 1521 is detachably connected to the first connection portion 1201, and the fourth connection portion 1520 is detachably connected to the second connection portion 1202.

[0063] Specifically, the first bracket 12 may include a first main board and two first side boards, the first main board extends from above one wheel 151 to above another wheel 151, the first side boards are located on both sides of the extension direction of the first main board, and the first connecting portion 1201 is located below the first side board and extends between the two wheels 151. Of course, the extension direction of the first connecting portion 1201 is the same as that of the wheel axle 153, so that the third connecting portion 1521 connected to the same wheel axle 153 can be connected to the same side of the first connecting portion 1201, that is, the third connecting portion 1521 is completely fitted with the corresponding surface of the first connecting portion 1201 facing the wheel 151, and can be connected by bolts or other Common accessories fix the third connection part 1521 to the first connection part 1201, and the second connection part 1202 is located on the side of the first side plate. The second connection part 1202 is arranged on both sides of the first side plate and is perpendicular to the first side plate. The fourth connection part 1520 is completely in contact with the side of the second connection part 1202 facing the ground. The third connection part 1521 and the first connection part 1201 can be fixed by bolts or other common accessories, so that the support member 15 is fixed to the first connection part 1201 and the second connection part 1202 from two mutually perpendicular directions, which effectively improves the fixing effect of the support member 15, thereby improving the stability of the wheel 151 when the turnout trolley is running.

[0064] Furthermore, two first connection parts 1201 are arranged side by side, and the two first connection parts 1201 are both located between the two wheel axles 153 , and two support members 15 for installing the same wheel axle 153 are correspondingly connected to the same first connection part 1201 .

[0065] This arrangement allows the position of the first connection portion 1201 to be adaptively adjusted according to the required spacing between the two wheels 151, making it easier to install the wheels 151.

[0066] In addition, the first bracket 12 also includes reinforcing ribs, which are used to connect the two first connecting parts 1201. It can be understood that the reinforcing ribs can be set at any position of the first connecting part 1201, and the number of reinforcing ribs can also be one or more. As long as the strength of the first connecting part 1201 can be improved and the two first connecting parts 1201 can be prevented from tilting and displacing during use, this embodiment does not limit it here.

[0067] For some possible implementations, see Figure 3 and Figure 5As shown, the mounting bracket also includes a connecting shaft 13, the second bracket 11 includes two fifth connecting parts 110 extending to the opposite sides of the first bracket 12 respectively, the fifth connecting part 110 is provided with a first connecting hole, and the first bracket 12 is provided with a second connecting hole adapted to the first connecting hole, the connecting shaft 13 is used to pass through the first connecting hole and the second connecting hole to connect the first bracket 12 and the second bracket 11, and enable the first bracket 12 to rotate relative to the second bracket 11 to adapt to trolley tracks of different shapes.

[0068] Among them, at least one second card slot 130 is provided at each end of the connecting shaft 13, and a second connecting member 14 is clamped in the second card slot 130. The second connecting member 14 and the fifth connecting part 110 are detachably connected to lock the first bracket 12 and the second bracket 11 through the second connecting member 14, that is, the second connecting member 14 is partially engaged in the second card slot 130, and the part exposed from the second card slot 130 is connected to the fifth connecting part 110. Of course, the second connecting member 14 and the fifth connecting part 110 can be connected by bolts or other common locking members, which will not be described in detail in this embodiment.

[0069] In addition, the configuration of the second connecting member 14 and the second slot 130 is similar to the configuration of the first connecting member 156 and the second slot 130 , and will not be described in detail in this embodiment.

[0070] The first bracket 12 and the second bracket 11 are locked by the second connecting member 14 and the second slot 130 , which can effectively reduce the difficulty of assembling and disassembling the first bracket 12 and the second bracket 11 , and further improve the convenience of maintenance of the switch trolley.

[0071] Exemplarily, the second bracket 11 may include a second main board, which is located above the first main board. The two fifth connecting parts 110 are connected to the opposite sides of the second main board. Of course, the position of the fifth connecting part 110 is preferably such that the connecting shaft 13 and the wheel shaft 153 are parallel, so that the second connecting member 14 is located on both sides of the trolley track, which is convenient for the staff to operate.

[0072] Among them, a plurality of mounting holes can be set on the second main board, and a plurality of mounting holes can be opened on the beam a correspondingly, and the bolts are screwed into the corresponding mounting holes to realize the connection between the second bracket 11 and the beam a.

[0073] It is understandable that the first connecting member 156 and the second connecting member 14 can be of any shape, as long as the first connecting member 156 can effectively connect the wheel axle 153 and the support member 15, and the second connecting member 14 can effectively connect the first bracket 12 and the second bracket 11, which will not be described in detail in this embodiment.

[0074] Exemplarily, both the first connecting member 156 and the second connecting member 14 are clamping plates, and the clamping plates are provided with at least two third connecting holes for fixing the clamping plates on the supporting member 15 or the second bracket 11 .

[0075] When two third connection holes are provided, the two third connection holes can be respectively located at two ends of the card plate to enhance the fixing effect and prevent the card plate from shifting.

[0076] See also Figure 1 As shown, an embodiment of the present application further provides a turnout trolley, which includes a crossbeam a and the turnout trolley wheel group structure 1 in the above embodiment.

[0077] like Figure 1 As shown, at least two turnout trolley wheel groups 151 are arranged side by side under the cross beam a. When two turnout trolley wheel group structures 1 are arranged, they are arranged at both ends of the cross beam a to effectively support the cross beam a.

[0078] Among them, the second bracket 11 of the turnout trolley wheel group structure 1 can be fixed on the crossbeam a by bolts, and the second bracket 11 is connected to the first bracket 12 by bolts. The staff can remove the bolts from the side of the trolley track to separate the first bracket 12 and the second bracket 11. When maintenance is needed, the first bracket 12 can be directly removed from the second bracket 11. The wheel 151 and the bearing 157 are installed on the wheel axle 153, and the wheel axle 153 is installed on the first bracket 12. Therefore, after removing the first bracket 12, these components can be detached from the main part of the turnout trolley along with the first bracket 12, without the need to move the turnout trolley as a whole from under the turnout beam body, which reduces the difficulty of maintenance of the turnout trolley and helps to shorten the maintenance cycle of the turnout trolley. At the same time, oil nozzles 154 are provided at both ends of the wheel axle 153, which can directly deliver the lubricating oil into the bearing 157 through the lubricating oil channel. That is, there is no need to separate the wheel axle 153, the wheel 151 and the bearing 157, so as to lubricate the bearing 157, thereby effectively reducing the difficulty of maintaining the bearing 157 and further shortening the maintenance cycle of the turnout trolley, thereby realizing the maintenance of the turnout trolley wheel group structure 1 during the window period of a line operation.
