[0001] This utility model relates to the field of bogie technology, specifically an intelligent bogie for an RGV electric flatcar. Background Technology
[0002] RGV electric flatbed carts are electric transport devices that run on fixed tracks and are widely used in factories, warehouses, logistics centers, and other scenarios to achieve automated material handling. RGV electric flatbed carts are equipped with bogies at the bottom, and the brake pads on the bogie axles need to be inspected during maintenance.
[0003] In the prior art, patent announcement number CN215284794U discloses an RGV trolley bogie, including two parallel side beams, a crossbeam installed between the side beams, a recessed portion located in the middle of the side beams to form a recess for installing the crossbeam, and a connecting beam hinged to both sides of the recessed portion and the upper part of the crossbeam; two drive assemblies, respectively disposed at both ends of the side beams; the drive assembly includes a drive motor disposed on the crossbeam, a rotating shaft connected to the drive motor and rotatably mounted between the connecting beams, and two sets of drive wheels disposed on the rotating shaft.
[0004] Brake pads are installed on the axles of the bogie of the trolley. The thickness of the brake pads directly affects the braking performance of the trolley. During vehicle maintenance, it is necessary to inspect the brake pads on the bogie axles. However, the chassis of the electric flatcar is low, and maintenance personnel can only observe the brake pads by lying on the ground, making it difficult to inspect the wear of the brake pads. Therefore, an intelligent bogie for the RGV electric flatcar is proposed. Utility Model Content
[0005] The purpose of this invention is to provide an intelligent bogie for RGV electric flatcars to solve the problems in the prior art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an intelligent bogie for an RGV electric flatcar, comprising a bogie body, an axle rotatably mounted on the bogie body, steering wheels rotatably mounted at both ends of the axle, brake pads fixedly mounted on the axle, a detection mechanism fixedly mounted at the brake pads, the detection mechanism comprising a mounting base fixedly mounted inside the bogie body, iron supports slidably mounted on both sides of the mounting base, a detection clamp arm fixedly mounted at the end of the iron supports, a detection probe fixedly mounted on the detection clamp arm with the detection probes aligned front to back, and a feedback component mounted on the mounting base.
[0007] Preferably, the detection mechanism further includes a movable groove formed on the mounting base, a reset spring is provided in the movable groove, an electromagnet is fixedly installed in the movable groove, and the electromagnet is aligned with the iron support column front and back.
[0008] Preferably, the detection clamp arm is provided with bolts, and the detection probe is fixedly installed on the detection clamp arm by bolts.
[0009] Preferably, the iron support column is slidably mounted on the mounting base via the movable groove, the detection clamp arm is movably mounted on both sides of the mounting base via the iron support column, one end of the reset spring is connected to the iron support column, and the other end of the reset spring is connected to the inside of the movable groove.
[0010] Preferably, the feedback component includes a docking leg fixedly installed inside an iron support column, a detection rack fixedly installed on the docking leg, a detection gear rotatably installed between the detection racks, an angle sensor fixedly installed on the mounting base, a linkage shaft between the angle sensor and the detection gear, and a data cable connected to the angle sensor.
[0011] Preferably, the mounting base has a mounting hole, and the linkage shaft is rotatably mounted in the mounting base through the mounting hole.
[0012] Preferably, the detection rack is fixedly mounted on the iron support column by the mating feet, one end of the linkage shaft is fixedly mounted on the output end of the angle sensor, the other end of the linkage shaft is fixedly mounted on the detection gear, and the angle sensor is provided with bolts at the edge, and the angle sensor is fixedly mounted on the mounting base by bolts.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. In this application, after the electromagnet is activated, the magnetic field it generates attracts the iron support column, causing it to move into the movable slot. The movement of the iron support column causes the two detection clamping arms to move closer together, thereby bringing the detection probe closer to the brake pad. As the wear of the brake pad increases, the length of the iron support column extending out of the movable slot increases accordingly. Therefore, by measuring the length of the iron support column extending out of the movable slot, the wear condition of the brake pad can be assessed.
[0015] 2. In this application, the extension of the iron support column drives the detection rack to move outward of the movable slot, thereby causing the detection gear to rotate. The rotation of the detection gear drives the input end of the angle sensor to rotate via the linkage shaft, thus realizing the measurement of the rotation angle of the detection gear. The rotation amplitude of the detection gear is positively correlated with the extension distance of the iron support column. Therefore, the angle sensor can be used to assess the wear condition of the brake pads, making it convenient for users to check the wear of the brake pads. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for an intelligent bogie for an RGV electric flatcar, including a bogie body 1, an axle 4 rotatably mounted on the bogie body 1, steering wheels 2 rotatably mounted at both ends of the axle 4, brake pads 3 fixedly mounted on the axle 4, a detection mechanism 5 fixedly mounted at the brake pads 3, and a feedback component 6 mounted on the mounting base 501. Through the cooperation of the detection mechanism 5 and the feedback component 6, the wear condition of the brake pads 3 can be quickly determined, making it convenient for users to inspect and maintain the bogie.
[0023] like Figure 2 and Figure 3As shown, the detection mechanism 5 includes a mounting base 501 fixedly installed inside the bogie body 1. Iron supports 505 are slidably installed on both sides of the mounting base 501. A detection clamp arm 506 is fixedly installed at the end of the iron support arm 505. A detection probe 507 is fixedly installed on the detection clamp arm 506, and the detection probe 507 is aligned front to back. The detection mechanism 5 also includes a movable groove 503 opened on the mounting base 501. A return spring 504 is provided in the movable groove 503. An electromagnet 502 is fixedly installed in the movable groove 503, and the electromagnet 502 is aligned front to back with the iron support arm 505. A bolt is provided on the detection clamp arm 506, and the detection probe 507 is fixedly installed on the detection clamp arm 506 by the bolt.
[0024] Specifically, when the electromagnet 502 is activated, it exerts its magnetic force to attract the iron support column 505, causing it to move into the movable slot 503. As the iron support column 505 moves into the movable slot 503, it further drives the two detection clamping arms 506 closer together. When the detection clamping arms 506 approach each other, they guide the detection probe 507 to also move closer to each other, thus approaching the brake pad 3. As the wear of the brake pad 3 increases, the iron support column 505 needs to extend a longer distance out of the movable slot 503 to contact the brake pad 3. Therefore, by measuring the distance the iron support column 505 extends out of the movable slot 503, we can accurately determine the wear condition of the brake pad 3.
[0025] like Figure 2 and Figure 4 As shown, the feedback component 6 includes a docking support 604 fixedly installed in the iron support column 505. A detection rack 603 is fixedly installed on the docking support 604. A detection gear 605 is rotatably installed between the detection racks 603. An angle sensor 601 is fixedly installed on the mounting base 501. A linkage shaft 602 is provided between the angle sensor 601 and the detection gear 605. A data cable 606 is connected to the angle sensor 601. A mounting hole is opened in the mounting base 501. The linkage shaft 602 is rotatably installed in the mounting base 501 through the mounting hole.
[0026] Specifically, the extension of the iron support 505 pushes the detection rack 603 outward along the direction of the movable slot 503. As the detection rack 603 moves outward from the movable slot 503, it further drives the detection gear 605 to rotate. During the rotation of the detection gear 605, power is transmitted through the linkage shaft 602, causing the input end of the angle sensor 601 to rotate accordingly. In this way, the angle sensor 601 can accurately measure the rotation angle of the detection gear 605. It is worth noting that the rotation amplitude of the detection gear 605 varies with the distance the iron support 505 extends. Therefore, by analyzing the rotation angle measured by the angle sensor 601, we can effectively determine the wear condition of the brake pad 3.
[0027] Working principle: When the vehicle stops, the electromagnet 502 can be activated. After the electromagnet 502 is activated, it will attract the iron support column 505, causing the iron support column 505 to move into the movable groove 503. When the iron support column 505 moves into the movable groove 503, it will drive the two detection clamping arms 506 to move closer to each other. When the detection clamping arms 506 move closer, they will drive the detection probe 507 to move closer to the brake pad 3. The more severe the wear of the brake pad 3, the longer the distance that the iron support column 505 extends out of the movable groove 503 will be. Thus, the wear condition of the brake pad 3 can be judged by the distance that the iron support column 505 extends out of the movable groove 503. Furthermore, the extension of the iron support 505 will cause the detection rack 603 to move outward from the movable slot 503. When the detection rack 603 moves outward from the movable slot 503, it will cause the detection gear 605 to rotate. When the detection gear 605 rotates, the linkage shaft 602 will cause the input end of the angle sensor 601 to rotate. Thus, the angle sensor 601 is used to measure the rotation angle of the detection gear 605. The data measured by the angle sensor 601 will be transmitted to the vehicle computer. Moreover, the rotation amplitude of the detection gear 605 changes with the extension distance of the iron support 505. Thus, the angle sensor 601 is used to determine the wear condition of the brake pad 3.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
