Technical Field

[0001] This utility model relates to the field of railway freight inspection technology, and in particular to an intelligent segmentation device for railway freight inspection. Background Technology

[0002] Railway freight inspection operations are divided into office and field operations. When a train enters the station, the office staff first check the three-sided images collected when the train passes through the line scan camera. After the check is completed, if there are any problems, the field freight inspection task needs to be issued in another system. The data of these two systems are independent of each other, which leads to the problem of data incompatibility, resulting in duplicated work and a fragmentation of the work process.

[0003] The existing railway freight inspection process typically involves segmenting the carriages using detection equipment such as magnets mounted on the rails. This equipment is usually bolted to the rails, which requires disassembling the bolts during maintenance, thus reducing the efficiency of maintenance. Therefore, the practicality of an intelligent segmenting device for railway freight inspection is needed. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide an intelligent segmentation device for railway freight inspection. This device can solve the problem that the segmentation work of existing railway freight inspection generally uses detection equipment such as magnets installed on the rails to detect the movement position of the carriages. However, the detection equipment is generally fixed to the rails with bolts, which requires the bolts to be removed during the maintenance of the detection equipment, thereby reducing the efficiency of the maintenance of the detection equipment. Therefore, this invention addresses the practicality of an intelligent segmentation device for railway freight inspection.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a railway freight inspection intelligent segmentation device, including a rail, wherein a mounting base plate is provided on the front side of the rail;

[0006] A fixing block is provided on the front side of the mounting base plate;

[0007] Among them, four countersunk holes are made on the front surface of the mounting base plate, and the countersunk holes extend out of the rear surface of the mounting base plate.

[0008] The mounting base plate is equipped with an installation mechanism, which includes bolts, a detection body, a reinforcing plate, a sliding groove, a sliding block, a support plate, a positioning groove, a fixing hole, a support groove, a support block, and a positioning spring.

[0009] Preferably, the four bolts are slidably fitted into the four countersunk holes;

[0010] The fixing block is located on the front side of the mounting base plate;

[0011] The detection body is fixedly connected to the front surface of the fixing block;

[0013] Preferably, the two sliding blocks are fixedly connected to the front surface of the mounting base plate;

[0014] Two sliding grooves are formed on the front surface of the fixed block, and the sliding grooves extend out of the rear surface of the fixed block.

[0015] The sliding block is slidably connected to the sliding groove.

[0016] Preferably, the positioning groove is formed on the left side surface of the sliding block and extends out of the right side surface of the sliding block;

[0017] Four fixing holes are provided on the outer surfaces of the left and right sides of the fixing block;

[0018] Two support slots are located on the left and right sides of the fixed block.

[0019] Preferably, the two support blocks are slidably connected to the two support grooves;

[0020] The outer surfaces of the two adjacent support blocks are both inclined.

[0021] Two support plates are fixedly connected to the outer surfaces of the two support blocks on opposite sides.

[0022] Preferably, the outer surfaces of the two adjacent sides of the support plates are in contact with the outer surfaces of the left and right sides of the fixing block;

[0023] Among them, four positioning springs are fixedly connected to the outer surfaces of the two adjacent support plates;

[0024] The end of the positioning spring away from the support plate extends into the corresponding fixing hole and is fixedly connected to the inner wall of the fixing hole.

[0025] Preferably, the outer surfaces of the two adjacent positioning springs extend into two corresponding sliding grooves;

[0029] Compared with the prior art, the beneficial effects of this utility model are:

[0030] 1. When the main body of the railway freight inspection intelligent segmentation device is damaged, the main body can be pulled forward simply by pulling out the support plate, which moves the support block out of the positioning groove. This separates the fixed block from the mounting base plate, thus enabling the disassembly of the main body. The disassembly is convenient, which facilitates the maintenance and disassembly of the main body, improves the maintenance efficiency of the main body, and increases the practicality of the railway freight inspection intelligent segmentation device.

[0031] 2. This intelligent segmented railway freight inspection device, under the action of the release force of the positioning spring, drives the support block to slide into the positioning groove. The support block slides into the positioning groove to fix the sliding block and the fixed block, so that the sliding block cannot be pulled out from the sliding groove, thereby realizing the fixed installation between the mounting base plate and the inspection body. The installation is convenient and quick. Attached Figure Description

[0042] Please see Figure 1-4 This utility model provides a technical solution: a railway freight inspection intelligent segmentation device, including a rail 1, and an installation base plate 2 is provided on the front side of the rail 1;

[0043] Among them, a fixing block 5 is provided on the front side of the mounting base plate 2;

[0044] Among them, four countersunk holes 3 are opened on the front surface of the mounting base plate 2, and the countersunk holes 3 extend out of the rear surface of the mounting base plate 2.

[0046] Furthermore, the four bolts 4 are slidably fitted into the four countersunk holes 3;

[0047] Among them, the fixing block 5 is set on the front side of the mounting base plate 2;

[0048] The monitoring body 6 is fixedly connected to the front surface of the fixing block 5;

[0049] Two reinforcing plates 7 are fixedly connected to the front surface of the fixing block 5, and the two reinforcing plates 7 are fixedly connected to the left and right outer surfaces of the monitoring body 6.

[0050] Furthermore, the two sliding blocks 9 are fixedly connected to the front surface of the mounting base plate 2;

[0051] Two sliding grooves 8 are formed on the front surface of the fixing block 5, and the sliding grooves 8 extend out of the rear surface of the fixing block 5.

[0052] The sliding block 9 is slidably connected to the sliding groove 8.

[0053] Furthermore, the positioning groove 11 is formed on the left side surface of the sliding block 9, and the positioning groove 11 extends out of the right side surface of the sliding block 9.

[0054] Four fixing holes 12 are provided on the outer surfaces of the left and right sides of the fixing block 5;

[0055] Two support grooves 13 are located on the left and right sides of the fixing block 5.

[0056] Furthermore, the two support blocks 14 are slidably connected to the two support grooves 13;

[0057] Among them, the outer surfaces of the two adjacent support blocks 14 are both inclined surfaces;

[0058] Two support plates 10 are fixedly connected to the outer surfaces of the two support blocks 14 on opposite sides.

[0059] Furthermore, the outer surfaces of the two adjacent sides of the two support plates 10 are in contact with the outer surfaces of the left and right sides of the fixing block 5.

[0060] Among them, four positioning springs 15 are fixedly connected to the outer surfaces of the two support plates 10 on both sides;

[0061] The end of the positioning spring 15 away from the support plate 10 extends into the corresponding fixing hole 12 and is fixedly connected to the inner wall of the fixing hole 12.

[0062] Furthermore, the outer surfaces of the two adjacent sides of the positioning springs 15 extend into the corresponding two sliding grooves 8;

[0063] Among them, the outer surfaces of the two adjacent positioning springs 15 are slidably connected to the two sliding blocks 9;

[0064] Among them, two positioning springs 15 are adapted to two positioning grooves 11, and the two positioning springs 15 and the two positioning grooves 11 are slidably connected;

[0065] The rear surface of the fixing block 5 is in contact with the front surface of the mounting base plate 2.

[0066] Furthermore, the core structure of the monitoring unit 6, which contains magnets, is a U-shaped permanent magnet encasing an induction coil. When a vehicle's wheel flange passes by, it cuts the magnetic lines of force generated by the magnet, causing a change in the magnetic flux of the coil. When a train section passes the magnet, the sensor calculates the position of the vehicle section by identifying the time difference between the signals of adjacent magnets. Typical applications of magnets in rail transit include position detection, speed monitoring, and safety assurance. When the wheel flange compresses the air gap, the magnetic resistance drops sharply, and the magnetic flux surges, causing the coil to generate an induced electromotive force. This signal is converted into a digital pulse by a shaping circuit for the control system to identify. Multiple magnets (such as magnets 1, 2, and 3) are installed at specific locations on the track, and the vehicle section is calculated using the time difference method.

[0067] Furthermore, when in operation, the electrical operation process of the railway ZR new wheel sensor (monitoring body 6) involves signal acquisition, transmission, processing, and collaborative work between devices, playing a key role in railway operation monitoring.

[0068] Signal Acquisition: When the train wheel flange passes the monitoring body 6, the coil inside the magnet will generate a corresponding magnetic induction electromotive force. The magnet adopts a single-pole double-loop magnet, which forms a good connection with the rail, enhances the magnetic flux effect, and the coil winding direction can avoid electromagnetic field interference generated by electric field lines, rail return current and track circuit.

[0069] Signal Output and Transmission: The monitoring unit 6 has two output leads: the red / brown wire is positive, and the white / blue wire is negative. The output signal level should be greater than 3 volts peak-to-peak (oscilloscope reading, no load) when the vehicle speed is greater than 4 km / h. The output leads should be connected to the same polarity external cables of the system's magnet plate. When connecting, it is recommended to solder the wire ends securely, seal them with heat shrink tubing, and then wrap them with insulating tape. The shielding wire should be cut off and properly insulated.

[0070] Signal Processing and Application: The output signal is transmitted to multiple railway monitoring systems, such as the infrared axle temperature detection system, the AEI vehicle number recognition system, and the 5T system. Different systems use different signal processing methods. For example, in the HBDS-II / III infrared equipment, the threshold voltage is typically adjusted from around 1V upwards, not exceeding 1.5V. The unused fourth input terminal on the system's magnet plate must be short-circuited, and the J1 short-circuit plug must be in the OFF position. For the 391 / 499 infrared equipment, if the lower three inputs are used, the adjustable input resistance on the magnet plate should be 3.6K-1.5K, and the threshold resistance should be around 10K. When using the upper three inputs, the adjustable threshold resistance on the magnet plate should be 80-180K, and the other three unused input terminals should be short-circuited. These systems utilize the signals collected by the monitoring entity 6 to perform axle counting, vehicle counting, and speed measurement operations, thereby monitoring and controlling the train's operating status.

[0071] Equipment Coordination and Calibration: After replacing the magnets in all infrared devices, the probe aiming point must be recalibrated to ensure that the equipment accurately acquires train-related information. In different systems, the installation position and parameter settings of the magnets must be strictly followed according to regulations. For example, there are clear standards for the distance between the outer edge of the magnet and the inner wall of the rail, the distance between the top of the magnet and the rail plane, and the center distance between magnets No. 2 and No. 3. Improper installation will lead to signal abnormalities and affect the normal operation of the system.

[0072] Furthermore, in use, the mounting base plate 2 is directly fixed to the rail 1 with bolts 4, and then the fixing block 5 is pushed into the mounting base plate 2, so that the two sliding blocks 9 slide into the two sliding grooves 8. During this process, the front surface of the two sliding blocks 9 contacts the inclined surface of the two support blocks 14 and pushes the inclined surface of the two support blocks 14, pushing the two support blocks 14 to move in opposite directions, thereby synchronously driving the two support plates 10 to move in opposite directions. During this process, the positioning spring 15 is stretched, causing the positioning spring 15 to be stretched and deformed. When the fixing block 5 is pushed backward until its rear surface contacts the front surface of the mounting base plate 2, the support block 14 is driven to slide into the positioning groove 11 under the action of the release elasticity of the positioning spring 15. The support block 14 slides into the positioning groove 11 to fix the sliding block 9 and the fixing block 5, so that the sliding block 9 cannot be pulled out from the sliding groove 8, thereby realizing the fixed installation between the mounting base plate 2 and the monitoring body 6. The installation is convenient and quick.

[0073] Furthermore, when the monitoring body 6 is damaged, simply pull out the support plate 10, causing the support plate 10 to move the support block 14 out of the positioning groove 11, and then pull the monitoring body 6 forward, separating the fixing block 5 from the mounting base plate 2, thereby disassembling the monitoring body 6. Disassembly is convenient, which in turn facilitates the maintenance and disassembly of the monitoring body 6, improves the maintenance efficiency of the monitoring body 6, and increases the practicality of the intelligent segmentation device for railway freight inspection.
