Technical Field

[0001] The present invention relates to the technical field of rail vehicles, and in particular to an accumulator mounting interface, a bogie frame and a suspended rail vehicle. Background Art

[0002] At present, rail trains need to use hydraulic braking systems to brake vehicles. In order to maintain the normal operation of the hydraulic braking system, accumulators need to be installed at corresponding positions on the train to convert the energy in the hydraulic braking system into compression energy or potential energy and store it at the appropriate time. When the hydraulic braking system needs it, the compression energy or potential energy is converted into hydraulic energy and released to replenish the hydraulic braking system.

[0003] In order to install the accumulator, it is necessary to set an accumulator mounting interface dedicated to installing the accumulator mounting bracket at the corresponding position of the rail vehicle, so that the accumulator mounting bracket used to install the accumulator can be installed on the train through the accumulator mounting interface. Since each type of accumulator corresponds to an accumulator mounting bracket, and each accumulator mounting bracket requires a corresponding accumulator mounting interface to be designed, the existing accumulator mounting interfaces have a wide variety and low versatility, resulting in the need to set up multiple types of accumulator mounting interfaces on the rail vehicle, and different types of accumulator mounting interfaces are not replaceable. Therefore, each accumulator mounting interface needs to be installed at a specific position of a specific rail train, resulting in a more complicated installation process of the accumulator mounting interface, and if there is an error in the size of the accumulator mounting interface, it is difficult to adjust the accumulator mounting interface to install the corresponding accumulator mounting bracket, and the entire accumulator mounting interface must be replaced; in addition, when part of the accumulator mounting interface is damaged, the entire accumulator mounting interface can only be replaced, resulting in a large waste of resources. Summary of the invention

[0004] The problem solved by the present invention is that there are many types of existing accumulator installation interfaces, which makes the installation process of the accumulator installation interface more complicated, and if part of the accumulator installation interface is damaged, the entire accumulator installation interface can only be replaced, which easily causes a large waste of resources.

[0005] To solve the above problems, the present invention provides an accumulator mounting interface, comprising a plurality of connection interfaces arranged at intervals, wherein the connection interfaces are of a wire holder type structure, and a single connection interface is suitable for fixing a wiring harness; the spacing distance and / or relative angle of two adjacent connection interfaces are suitable for adjustment, and the plurality of connection interfaces are suitable for cooperating to install different types of accumulator mounting brackets, and the accumulator mounting brackets are suitable for installing accumulators.

[0006] Furthermore, it comprises two connection interfaces which are arranged at intervals, and the two connection interfaces are suitable for matching to install the accumulator mounting bracket.

[0007] Furthermore, the connection interface is a rectangular parallelepiped structure, and a connection hole is provided on the connection interface. A single connection interface is suitable for being connected to one end of the accumulator mounting bracket through the connection hole.

[0008] Furthermore, the connecting hole is an oblong hole.

[0009] Furthermore, connection holes are respectively provided at both ends of the connection interface, and a weight-reducing hole is also provided on the connection interface. The connection interface is a symmetrical structure. The two connection holes are symmetrically arranged on the connection interface, and the weight-reducing hole is arranged between the two connection holes. The distance between the weight-reducing hole and the two connection holes is the same, and the weight-reducing hole is a symmetrical structure.

[0010] Furthermore, the connection interface is provided with a second connection structure, and the lower support beam of the suspended rail vehicle is provided with a first connection structure, and the connection position of the first connection structure and the second connection structure is suitable for adjusting to change the relative position of the connection interface and the lower support beam.

[0011] The present invention also provides a bogie frame, comprising the accumulator mounting interface as described above.

[0012] Further, it includes a frame upper beam, the frame upper beam includes an upper support beam and a lower support beam connected to each other, and the accumulator installation interface is respectively provided on both longitudinal sides of the lower support beam. Further, the bogie frame also includes a wire clamping seat, the wire clamping seat is used to fix the wire harness, and the structure of the connection interface of the accumulator installation interface is the same as that of the wire clamping seat.

[0013] The present invention also provides a suspended rail vehicle, comprising the bogie frame as described above.

[0014] The beneficial effects of the present invention are as follows: by setting the accumulator mounting interface to include a plurality of spaced connection interfaces, different types of accumulator mounting brackets can be adapted to the corresponding accumulator mounting brackets by changing the spacing distance of the plurality of connection interfaces and / or the setting angle of the connection interfaces, thereby improving the versatility of the accumulator mounting interface; in addition, when a certain connection interface is damaged, only the damaged connection interface needs to be replaced, thereby effectively avoiding waste of resources; at the same time, since the connection interface is a wire clamping seat structure, the wire clamping seat can be directly used as the connection interface, without the need to redesign the structure of the connection interface or add special manufacturing equipment, thereby effectively reducing the overall cost; and a single connection interface can be used as a wire clamping seat to fix the wiring harness, and a plurality of connection interfaces can be used in conjunction with the installation of the accumulator mounting bracket, so that during the train installation process, the connection interface can be used interchangeably with the wire clamping seat, which can effectively avoid the situation where the wire clamping seat or the connection interface is redundant or insufficient, and has strong versatility and replaceability.

[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0022] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "rear", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0023] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0024] As shown in the accompanying drawings, an XYZ coordinate system is provided, wherein the positive direction of the X axis represents "left", the negative direction of the X axis represents "right", the positive direction of the Y axis represents "front", the negative direction of the Y axis represents "back", the positive direction of the Z axis represents "up", and the negative direction of the Z axis represents "down".

[0025] In this embodiment, the vertical direction refers to the Z-axis direction, the horizontal direction refers to the X-axis direction, and the longitudinal direction refers to the Y-axis direction.

[0026] like Figures 1 to 4As shown, the present invention provides an accumulator mounting interface, comprising a plurality of connection interfaces 1 arranged at intervals, wherein the connection interface 1 is a wire holder structure, and a single connection interface 1 is suitable for fixing a wiring harness; the spacing distance and / or relative angle of two adjacent connection interfaces 1 are suitable for adjustment, and the plurality of connection interfaces 1 are suitable for cooperating to install different types of accumulator mounting brackets 4, and the accumulator mounting bracket 4 is suitable for installing an accumulator 5.

[0027] Among them, the connection interface 1 can be connected to the accumulator mounting bracket 4 first, and then the connection interface 1 can be connected to the corresponding position on the train, and then the accumulator can be installed on the accumulator mounting bracket 4. The accumulator mounting bracket 4 can also be measured first to determine the spacing distances and relative angles of each connection interface 1, and then each connection interface 1 can be set at the corresponding position of the train according to the determined spacing distances and relative angles of each connection interface 1, and then the accumulator mounting bracket 4 can be connected to each connection interface 1. A plurality of wire clamping seats 6 need to be set on the train to fix the wires on the train. Generally, the structure of each wire clamping seat 6 is the same. In this embodiment, the structure of the optional connection interface 1 is the same as the structure of the common wire clamping seat 6 on the train, that is, the wire clamping seat 6 is as follows Figure 4 The structure shown.

[0028] Specifically, the connection interface 1 can have the same structure as the wire holder 6, and a plurality of connection holes 11 are provided on the connection interface 1. The connection interface 1 is connected to the accumulator mounting bracket 4 through the connection holes 11. If there is no matching hole corresponding to the connection hole 11 on the accumulator mounting bracket 4 or the position of the matching hole is incorrect, a corresponding matching hole can be drilled on the accumulator mounting bracket 4 by a corresponding drill, or a new connection hole 11 can be drilled on the connection interface 1 by a corresponding drill, so as to realize the connection between the connection interface 1 and the accumulator mounting bracket 4, thereby avoiding the need to replace the accumulator mounting bracket 4 or the connection interface 1.

[0029] Optionally, the connection interface 1 is a rectangular parallelepiped structure, and a connection hole 11 is provided on the connection interface 1 . A single connection interface is suitable for being connected to one end of the accumulator mounting bracket 4 through the connection hole 11 .

[0030] In applications, the sizes and shapes of various accumulator mounting brackets 4 may be different, but various accumulator mounting brackets 4 are often provided with connecting parts corresponding to the accumulator mounting interface at both ends in a certain direction, and corresponding matching holes are provided on the connecting parts. Although the accumulator mounting brackets 4 are all provided with connecting parts, the distances between the connecting parts at both ends of different accumulator mounting brackets 4 are different, and / or the directions in which the connecting parts of different accumulator mounting brackets 4 are provided are different. For example, the first accumulator mounting bracket 4 is provided with connecting parts at the upper and lower ends, and the second accumulator mounting bracket 4 is provided with connecting parts at the left and right ends. Therefore, in the above case, different accumulator mounting brackets 4 often require different accumulator mounting interfaces for connection.

[0031] In this embodiment, the accumulator mounting interface includes a plurality of spaced connection interfaces 1, that is, the spaced distance of the connection interfaces 1 can be changed, thereby solving the problem of different distances between the connection parts at both ends of different accumulator mounting brackets 4. In addition, the relative angles of different connection interfaces 1 can be adjusted, thereby solving the problem of different directions of the connection parts of different accumulator mounting brackets 4. Therefore, the accumulator mounting interface described in this embodiment can be applied to different types of accumulator mounting brackets 4, and its versatility is relatively strong.

[0032] Optionally, the connecting hole 11 is an oblong hole.

[0033] Specifically, the connection interface 1 is connected to the accumulator mounting bracket 4 by bolts. By setting the connection hole 11 as an oblong hole, the relative position of the connection interface 1 and the accumulator mounting bracket 4 can be adjusted. In addition, the oblong hole also has a higher fault tolerance rate, and only a part of the oblong hole needs to be aligned with the matching hole on the accumulator mounting bracket 4.

[0034] In this embodiment, the connection interface 1 can be connected to the bogie frame and the accumulator mounting bracket 4 respectively by bolts, and the connection hole on the connection interface 1 corresponding to the bogie frame is defined as a first connection hole, and the connection hole 11 on the connection interface corresponding to the accumulator mounting bracket 4 is defined as a second connection hole, and the first connection hole and the second connection hole can both be set as oblong holes, so that after the connection interface 1 is connected to the bogie frame and / or the accumulator mounting bracket 4, the relative position of the connection interface 1 and the bogie frame and / or the accumulator mounting bracket 4 can still be adjusted, wherein the extension directions of the first connection hole and the second connection hole can be the same or different, and through the above-mentioned setting, the spacing distance and / or relative angle of two adjacent connection interfaces 1 can be adjusted.

[0035] Taking the connection interface 1 and the bogie frame as an example, when the position of the connection interface 1 on the bogie frame needs to be adjusted, the nut is rotated so that the bolt no longer fastens the connection interface 1 to the bogie frame. After the nut is rotated, the connection interface 1 is moved, and after the connection interface 1 is moved to a predetermined position along the first connection hole or the matching hole, the connection interface 1 is fastened to the bogie frame again by the bolt, thereby completing the position adjustment of the connection interface 1 on the bogie frame.

[0036] By setting the accumulator mounting interface to include multiple spaced connection interfaces 1, different types of accumulator mounting brackets 4 can be adapted to the corresponding accumulator mounting brackets 4 by changing the spacing distance of the multiple connection interfaces 1 and / or the setting angle of the connection interfaces 1, thereby improving the versatility of the accumulator mounting interface; in addition, when a certain connection interface 1 is damaged, only the damaged connection interface 1 needs to be replaced, thereby effectively avoiding waste of resources; at the same time, since the connection interface 1 is a wire clamping seat structure, the wire clamping seat 6 can be directly used as the connection interface 1, without redesigning the structure of the connection interface 1 or adding special manufacturing equipment, effectively reducing the overall cost; and a single connection interface 1 can be used as a wire clamping seat 6 to fix the wiring harness, and multiple connection interfaces 1 can be used to install the accumulator mounting bracket 4, so that during the train installation process, the connection interface 1 can be used interchangeably with the wire clamping seat 6, which can effectively avoid the situation where the wire clamping seat 6 or the connection interface is redundant or insufficient, and it has strong versatility and replaceability.

[0037] Optionally, two connection interfaces 1 are arranged at intervals, and the two connection interfaces 1 are suitable for matching to install the accumulator mounting bracket 4 .

[0038] In application, the accumulator mounting bracket 4 can be fixed on the train by only fixing the two ends of the accumulator mounting bracket 4. Therefore, the accumulator mounting bracket 4 is generally only provided with connecting parts at both ends. Correspondingly, only two connecting interfaces 1 are needed to realize the fixing of the accumulator mounting bracket 4.

[0039] Optionally, the plurality of connection interfaces 1 are arranged along a width direction of the connection interface 1 .

[0040] in, Figure 1 and Figure 2 If the setting direction of the connection interface 1 in is different, then Figure 1 and Figure 2 The width direction of the connection interface 1 in is different. Figure 1 In the embodiment, the width direction of the connection interface 1 is the Z-axis direction, and the width direction of the connection interface 1 is the X-axis direction; Figure 2 In the figure, the width direction of the connection interface 1 is the X-axis direction, and the width direction of the connection interface 1 is the Z-axis direction.

[0041] Specifically, the length of the connection interface 1 is greater than the width of the connection interface 1, that is, the connection interface 1 can be provided with more connection holes 11 in the length direction relative to the width direction. In this case, if the specific accumulator mounting bracket 4 is not determined, then if multiple connection interfaces 1 are arranged along the length direction of the connection interface 1, for the accumulator mounting interface, it is easy for the connection interface 1 to have multiple connection holes 11 in the length direction, while there are fewer connection holes 11 in the width direction of the connection interface 1. The accumulator mounting interface has a high probability that only a small number of connection holes 11 can be connected to the accumulator mounting bracket 4, thereby making the connection between the connection interface 1 and the accumulator mounting bracket 4 less stable. In the case where multiple connection interfaces 1 are arranged along the width direction of the connection interface 1, the connection interface 1 has a high probability of having multiple connection points with the accumulator mounting bracket 4, thereby making the connection between the connection interface 1 and the accumulator mounting bracket 4 more stable.

[0042] In application, if the specific accumulator mounting bracket 4 is known, it is necessary to design the arrangement direction of the plurality of connection interfaces 1 according to the specific accumulator mounting bracket 4 .

[0043] Alternatively, if Figure 4 As shown, connection holes 11 are respectively provided at both ends of the connection interface 1 .

[0044] Specifically, by providing connection holes 11 at both ends of the connection interface 1, the connection points of the connection interface 1 and the accumulator mounting bracket 4 are at a longer distance in the length direction of the connection interface 1, and the distances between the edge points of the accumulator mounting bracket 4 in this direction and the nearest connection points are shorter, thereby making the force arm between the edge points of the accumulator mounting bracket 4 and the nearest connection points smaller, so that the connection between the connection interface 1 and the accumulator mounting bracket 4 is more firmly connected.

[0045] Among them, the connection hole 11 in the present application is preferably a threaded hole, so that the connection interface 1 can be threadedly connected to the accumulator mounting bracket 4, so that the connection interface 1 and the accumulator mounting bracket 4 are detachable.

[0046] Alternatively, if Figure 4 As shown, the connection interface 1 is also provided with a weight-reducing hole 12 .

[0047] In this embodiment, the connection interface 1 is arranged on the bogie frame, and the heavy weight of the bogie is not conducive to the steering of the train. Therefore, in this embodiment, weight-reducing holes 12 are arranged on the connection interface 1 to reduce the weight of the connection interface 1, thereby reducing the overall weight of the bogie, thereby facilitating the lightweighting of the bogie.

[0048] Among them, the weight reduction hole 12 can be Figure 1 and Figure 2 The oblong hole shown in the figure may also be a through hole or a blind hole of other shapes.

[0049] Optionally, the connection interface 1 is a symmetrical structure, the two connection holes 11 are symmetrically arranged on the connection interface 1, the weight reduction hole 12 is arranged between the two connection holes 11, and the weight reduction hole 12 is at the same distance from the two connection holes 11, and the weight reduction hole 12 is a symmetrical structure.

[0050] The connecting hole 11 may be a circular hole.

[0051] Specifically, by defining the structures of the connection interface 1, the weight-reducing holes 12 and the connection holes 11, and the locations of the weight-reducing holes 12 and the connection holes 11 on the connection interface 1 as defined above, the connection interface 1 provided with the weight-reducing holes 12 and the connection holes 11 is still a symmetrical structure, thereby making the structure of the connection interface 1 symmetrical and relatively asymmetrical, without obvious structural weak points, so that the connection interface 1 is relatively not prone to damage when used as a supporting structure.

[0052] Optionally, a first connecting structure is provided on the lower support beam 22, and a corresponding second connecting structure is provided on the connecting interface 1 of the accumulator mounting interface, and the connecting position of the first connecting structure and the second connecting structure is suitable for adjustment to change the relative position of the connecting interface 1 and the lower support beam 22.

[0053] Wherein, at least one of the first connection structure and the second connection structure is an arc-shaped connection hole, such as the aforementioned oblong hole.

[0054] Taking the example that both the first connection structure and the second connection structure are oblong holes, the connection interface 1 is connected to the lower support beam 22 by bolts. When it is necessary to adjust the position of the connection interface 1 on the lower support beam 22, the nut is rotated so that the bolt no longer fastens the connection interface 1 to the bogie frame. After the nut is rotated, the connection interface 1 is moved. After the connection interface 1 moves to a predetermined position along the first connection structure or the second connection structure, the connection interface 1 is fastened to the bogie frame again by bolts. Thus, the position adjustment of the connection interface 1 on the lower support beam 22 is completed, and the position adjustment of the connection interface 1 on the bogie frame is realized. Therefore, after the connection interface 1 is connected to the lower support beam 22, the relative position of the connection interface 1 and the lower support beam 22 can still be adjusted.

[0055] like Figure 1 and Figure 2 As shown, a bogie frame according to another embodiment of the present invention comprises the accumulator mounting interface as described above.

[0056] The beneficial effects of the bogie frame described in this embodiment relative to the prior art are the same as the beneficial effects of the accumulator mounting interface described in this embodiment relative to the prior art, and will not be repeated here.

[0057] Optionally, a frame upper beam 2 is included, wherein the frame upper beam 2 includes an upper support beam 21 and a lower support beam 22 connected to each other, and the accumulator installation interface is respectively provided on both longitudinal sides of the lower support beam 22.

[0058] Among them, Figure 1 and Figure 2 As shown, the two longitudinal side surfaces of the lower supporting beam 22 are the front and rear side surfaces of the lower supporting beam 22 .

[0059] In this embodiment, Figure 1 and Figure 2 As shown, a hydraulic control unit bracket 3 is provided on the upper surface of the upper bracket, and the hydraulic control unit bracket 3 is used to support the hydraulic control unit and the auxiliary hydraulic control unit. The hydraulic control unit is used to brake the rail train, and the auxiliary hydraulic control unit is used to perform auxiliary braking of the rail train. Therefore, it is necessary to set corresponding accumulators 5 corresponding to the hydraulic control unit and the auxiliary hydraulic control unit. The structures of the two accumulators 5 corresponding to the hydraulic control unit and the auxiliary hydraulic control unit are different, so the corresponding accumulator mounting brackets 4 are also different. It is necessary to adjust the setting distance of the two connection interfaces 1 and the setting direction of the connection interface 1 according to the corresponding accumulator mounting bracket 4, as shown in FIG. Figure 1 and Figure 2 As shown, the connection interface 1 on one side of the lower support beam 22 is arranged horizontally, and the connection interface 1 on the other side of the lower support beam 22 is arranged vertically.

[0060] Optionally, the connection interface 1 is provided at the top end of the lower support beam 22 .

[0061] In this embodiment, Figure 1 and Figure 2 As shown, a hydraulic control unit bracket 3 is provided on the upper surface of the upper bracket, and the hydraulic control unit bracket 3 is used to support the hydraulic control unit and the auxiliary hydraulic control unit. The accumulators 5 on the two side surfaces of the lower support beam 22 are energy storage devices corresponding to the hydraulic control unit box and the auxiliary hydraulic control unit, respectively. Therefore, in order to facilitate the accumulator 5 to realize its function, the accumulator 5 needs to be installed at a position close to the hydraulic control unit or the auxiliary hydraulic control unit. Based on this consideration, the accumulator 5 can be installed on the longitudinal side surface of the lower support beam 22 or on the upper surface of the upper support beam 21, but because the upper surface of the upper support beam 21 also needs to be installed with structures such as a current collector, it is preferred to install the accumulator installation interface on the top of the two longitudinal side surfaces of the lower support beam 22, and then install the accumulator 5 on the top of the two longitudinal side surfaces of the lower support beam 22.

[0062] Optionally, the bogie frame further comprises a wire holder 6, which is used to fix the wire harness, and the structure of the connection interface 1 of the accumulator mounting interface is the same as that of the wire holder 6. Through the above arrangement, the connection interface can be common with the wire holder 6, which can effectively avoid the situation where the wire holder 6 or the connection interface is redundant or insufficient, and improve the versatility of the connection interface and / or the wire holder 6.

[0063] A suspended rail vehicle according to another embodiment of the present invention comprises the bogie frame as described above.

[0064] The beneficial effects of the suspended rail vehicle described in this embodiment relative to the prior art are the same as the beneficial effects of the bogie frame described in this embodiment relative to the prior art, and will not be repeated here.

[0065] Although the disclosure is disclosed as above, the protection scope of the disclosure is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the disclosure, and these changes and modifications will fall within the protection scope of the present invention.
