[0001] The utility model relates to rail transit safety technical field, in particular to a train bogie sensor's mounting structure and train bogie. BACKGROUND

[0002] In the related art, heavy haul train is an important tool of railway transportation industry, and it is crucial to ensure the safety of train running, and the vibration detection of train is one of the means. In the prior art, various detection structures are designed for train vibration detection, such as: (1) Patent: CN 214844030 U, a mounting structure of a rail train bogie structure detection sensor, the patent application discloses a detection sensor mounting structure for a rail train bogie, which comprises a box body, a bearing plate is fixedly connected to the bottom of the box body through a damping spring, a recess is formed in the upper surface of the bearing plate, and a mounting hole for fixing the sensor is arranged on the bearing plate.

[0003] However, these mounting structures of vibration sensors also have some problems, mainly concentrated in the following aspects: 1) complex installation: the installation process of the vibration sensor is relatively complex, and the sensor is relatively expensive, which requires professional personnel to install and debug; 2) sensor interface stress: when the train turns, the bogie will turn, but the car body will not turn much. At this time, the cable will be pulled tight. If the cable is too short or other reasons cause the cable to be not long enough, the stress point will exist at the interfaces on both sides of the cable, one is the case socket, and the other is the sensor interface. After the sensor interface is stressed, it will be damaged and only the sensor can be replaced, which is costly; 3) low separation efficiency: the traditional cable installation method can only separate from the sensor interface. The sensor interface has threads and is relatively thin, which needs to be disassembled for a certain time. UTILITY MODEL CONTENTS

DETAILED DESCRIPTION

[0032] The utility model will be further described below with reference to the drawings.

[0033] As Figures 1-2 shown, the utility model provides a train bogie 20 sensor's installation structure 10, sensor can be vibration sensor etc., this installation structure 10 includes: sensor support 101 and separate jack 102 etc.

[0034] As Figures 2-5 shown, sensor support 101 includes fixed bottom plate 1011 and cover plate 1012 etc. Fixed bottom plate 1011 is fixed on train bogie 20, can adopt adhesive, welding or set fastener etc. Fixed mode realizes the relative fixation of both. Cover plate 1012 is set on fixed bottom plate 1011, and cover plate 1012 cooperates with fixed bottom plate 1011 and forms sensor installation cavity, and cover plate 1012 is equipped with jack installation part 10122.

[0035] Separate jack 102 is set on jack installation part 10122 as cable connecting piece, is used to connect sensor and train's machine case. Exemplarily, separate jack 102 includes plug and socket, wherein plug portion can be fixed on jack installation part 10122 and is directly connected with the cable of machine case, and the cable portion of sensor is connected to socket, and the connection / separation of machine case and sensor can be realized by plugging operation to socket and plug. It needs to be explained that the cable of sensor can also be directly designed as the socket structure that can cooperate with the plug of separate jack 102, at this time, the connection of train machine case and corresponding sensor can be completed by the plug connection of the lead-out end of sensor and plug.

[0036] In the embodiment, sensor is fixed on the side frame of train bogie 20 through sensor support 101, since the cable of sensor is connected to machine case after passing through separate jack 102, wherein separate jack 102 is fixed on the sensor support 101, and the cable can be manually separated. Based on this, the improved installation structure 10 has at least two advantages: first, when bogie and car body are separated, the cable can be easily separated, without the need to separate at sensor interface; second, the stress point is transferred to separate jack 102, when car and bogie are offset, the force generated will be on the cable from train car to separate jack 102, instead of acting on sensor interface, which can effectively prevent the damage of sensor interface due to cable pulling, improve the service life of sensor, and reduce the use cost.

[0037] In some embodiments, to facilitate efficient sensor assembly and disassembly, the connection between the cover plate 1012 and the fixed base plate 1011 can be optimized to allow for detachable connection. For example, fasteners can be provided or a snap-fit ​​structure can be provided at the corresponding joints between the cover plate 1012 and the fixed base plate 1011.

[0038] In some embodiments, considering that the cover plate 1012 cooperates with the fixed base plate 1011 to form a sensor installation cavity, both the cover plate 1012 and the fixed base plate 1011 can be optimized simultaneously. For example, corresponding surfaces of the fixed base plate 1011 and the cover plate 1012 are deformed inward to form grooves. When the cover plate 1012 is placed on the corresponding position of the fixed base plate 1011, the grooves on the cover plate 1012 align with the grooves on the fixed base plate 1011, forming the desired sensor installation cavity at the corresponding position, thereby allowing the sensor to be installed.

[0039] Considering the processing cost and other factors, the groove can be formed on the surface of only one of the cover plate 1012 and the fixed base plate 1011. Figure 3 、 Figure 5 As shown, the fixed base plate 1011 has a mounting plane, and the bottom side of the cover plate 1012 is concave to form a mounting groove 10123 for accommodating the sensor. The cover plate 1012 and the fixed base plate 1011 are assembled so that the mounting groove 10123 corresponds to the mounting plane to form the required sensor mounting cavity.

[0040] In addition, to facilitate the routing of sensor cables, the walls of the mounting groove 10123 may be opened. For example, the walls of the mounting groove 10123 are provided with a wire-passing opening 10125 for routing cables. It should be noted that when corresponding positions on the surfaces of the fixed base plate 1011 and the cover plate 1012 are both recessed to form grooves, the wire-passing opening 10125 may be provided on the walls of either groove, or may be provided on the edges of both grooves to form a small notch, with the two small notches joined together to form the desired wire-passing opening 10125.

[0041] In some embodiments, during the train movement, the train bogie 20 will also drive the sensor on the sensor bracket 101 to move together. In order to prevent the sensor's own vibration from affecting the measurement results and being damaged due to its own vibration, the sensor in the sensor installation cavity can be fixed. For example, Figure 3 As shown, a filling groove 10124 is provided in the mounting groove 10123. The filling groove 10124 is used to fill glue to fix the sensor. It should be noted that the glue filled in the mounting groove 10123 can be a sealant or the like.

[0042] Alternatively, as Figure 3As shown, the filling grooves 10124 can be formed along the direction from the groove opening to the groove bottom of the mounting groove 10123 for facilitating the filling of the glue. The number of the filling grooves 10124 can be determined according to the shape and size of the mounting groove 10123 and the type of the glue to be filled. For example, when the mounting groove 10123 is a square groove and the glue to be filled is a sealant, four filling grooves 10124 can be formed at the four edges of the square mounting groove 10123 along the groove depth direction, so as to ensure that sufficient sealant can be filled in the mounting groove 10123 and the fixation effect of the sensor can be avoided from being affected by the insufficient filling of the sealant.

[0043] In some embodiments, as shown in Figure 5 The fixing bottom plate 1011 includes a vertical plate 10112 and a horizontal plate 10111. The vertical plate 10112 is fixed on the side frame of the train bogie 20, and the horizontal plate 10111 is vertically arranged on the side of the vertical plate 10112 away from the train bogie 20. The vertical plate 10112 and the horizontal plate 10111 of the fixing bottom plate 1011 form a “T-shaped plate”, wherein the cover plate 1012 is arranged on the upper side of the horizontal plate 10111, and the upper side of the horizontal plate 10111 cooperates with the mounting groove 10123 to form a sensor mounting cavity.

[0044] In addition, in order to ensure the support reliability of the vertical plate 10112 and the horizontal plate 10111, reinforcing ribs can be additionally arranged at the corresponding positions of the fixing bottom plate 1011, so as to increase the connection strength between the vertical plate 10112 and the horizontal plate 10111. For example, a rib plate 10114 is arranged at the lower side of the horizontal plate 10111 and the plate surface of the corresponding vertical plate 10112, and the rib plate 10114 is perpendicular to the horizontal plate 10111 and the vertical plate 10112, respectively.

[0045] In some embodiments, considering that the cover plate 1012 and the fixing bottom plate 1011 are detachably connected, the fastener can be configured to achieve the detachable connection. For example, as shown in Figures 3-5 The horizontal plate 10111 is provided with a first hole 10113, and the part of the cover plate 1012 surrounding the side of the mounting groove 10123 is provided with a second hole 10121, wherein the first hole 10113 and the second hole 10121 are connected by a fastener. It should be noted that the fastener can be a bolt assembly.

[0046] In the embodiment, the sensor support 101 is installed on the side frame of the train bogie 20, and the sensor is installed in the sensor installation cavity formed by the cover plate 1012 and the fixed bottom plate 1011 of the sensor support 101. First, the sensor is installed in the sensor installation cavity, and then the first hole 10113 and the second hole 10121 are fastened by the bolt assembly, so that the sensor is installed in the sensor support 101. Not only the stability of the sensor can be ensured, but also the detachable connection between the sensor and the train cabinet can be realized after the corresponding cable is connected in combination with the setting of the separation jack 102. When the bogie and the car body need to be separated, the separation jack 102 is manually operated, so that the cable can be quickly separated, and the cumbersome operation of separating the cable at the sensor interface is avoided.

[0047] The installation structure 10 is provided with the separation jack 102, so that the cable from the cabinet to the sensor can be easily separated, and the installation and maintenance process of the sensor is simplified. Unlike the connection mode of the sensor in the traditional installation structure 10, when the sensor is maintained and repaired, the cable does not need to be separated at the sensor interface, so that the operation time and complexity are reduced. In addition, due to the setting of the separation jack 102, the stress point can also be transferred. Specifically, when the train turns, the bogie will produce relative displacement, so that the cable is pulled and tightened. By fixing the separation jack 102 on the sensor support 101, the stress point is transferred to the separation jack 102, so that the sensor interface is not directly stressed, thereby preventing the sensor interface from being damaged.

[0048] In some embodiments, considering that the separation jack 102 needs to be as close as possible to the installation position of the sensor, the separation jack can be fixed at the corresponding position of the top side of the cover plate 1012 or the outer side wall of the installation groove 10123. For example, as shown in Figure 4 The jack mounting portion 10122 includes a vertical plate provided on the top side of the cover plate 1012, and a jack mounting hole is formed in the vertical plate, and the separation jack is arranged in the jack mounting hole.

[0049] After the sensor is installed in the sensor installation cavity, the direction of the cable led out through the wire port 10125 is also determined. In order to facilitate the connection between the led-out cable and the separation jack 102, the opening direction of the jack mounting hole can also be adjusted, so that the plug of the separation jack 102 is inserted in the same direction as the socket. Alternatively, the opening direction of the jack mounting hole is consistent with the wire-out direction of the sensor led-out cable in the installation groove 10123 of the cover plate 1012.

[0050] The utility model also provides a train bogie 20, like Figures 1-5As shown, the train bogie 20 comprises a bogie body, the mounting structure 10 of any one of the above and the sensor arranged in the mounting structure 10.

[0051] Since the sensor is fixed in the sensor mounting cavity of the sensor support 101 and is detachably connected with the case through the separate jack 102 on the sensor support 101, on the one hand, the installation and disassembly process is simplified, the installation and maintenance of the sensor are more convenient, and the dependence on professionals is reduced; on the other hand, the stress on the sensor interface is reduced, when the train turns, the cable is stretched and tightened, the tensile force generated by the cable being stretched and tightened can be avoided to be conducted to the sensor interface, the sensor interface can be avoided to be damaged by being pulled, and the cost of replacing the sensor is reduced.

[0052] In addition, considering that abrasion or breakage can also be caused by the pulling operation of disassembling and assembling the cable at the connection between the cable and the separate jack 102, optionally, the cable can be a flexible cable, and based on the use of the high-flexibility cable, the cable can withstand greater stretching and bending.

[0053] Although the utility model has been described with reference to the preferred embodiments, various improvements can be made and the components therein can be replaced with equivalents without departing from the scope of the utility model. In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any way. The utility model is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
