Description

Technical Field

[0001] This utility model relates to the field of railway signal detection technology, and in particular to a railway signal receiving and detection device. Background Technology

[0002] As a key infrastructure for ensuring the safety and efficiency of railway transportation, railway signaling equipment faces higher requirements for maintenance and management due to the widespread application of advanced technologies such as microprocessors and electronic devices. Specifically, this manifests in a significant increase in the number of inspection items and a substantial improvement in inspection accuracy. At the same time, the railway equipment maintenance mode is shifting from traditional fault repair to condition-based maintenance, which has led to a significant increase in the workload of inspection.

[0003] Most existing railway signal receiving and detection devices are placed close to the main railway line. As trains or high-speed trains pass by, the vibrations generated between the train and the rails are transmitted to the detection box, which can easily affect the stability of the internal wiring. Prolonged vibration can cause the wiring to detach, affecting the normal operation of the detection box. Utility Model Content

[0004] The purpose of this utility model is to solve the following shortcomings in the existing technology: most existing railway signal receiving and detection devices are placed close to the railway main line. As trains or high-speed trains pass by, the vibration generated between the train and the rails will be transmitted to the detection box, which can easily affect the stability of the fixed circuit inside the detection box. Long-term vibration can cause the circuit to detach, affecting the normal operation of the detection box. Therefore, a railway signal receiving and detection device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A railway signal receiving and detection device includes a base and a detection box, wherein multiple shock-absorbing cylinders are fixedly connected to the base;

[0007] The testing box is equipped with anti-loosening components, which include an anti-loosening cylinder, a rotating shaft, an anti-loosening ring, a placement plate, a fastening plate, a pressure rod, and a pressing rod. The anti-loosening cylinder is fixedly connected to the testing box, the rotating shaft is rotatably connected inside the anti-loosening cylinder, the anti-loosening ring is fixedly connected inside the anti-loosening cylinder, multiple placement plates are fixedly connected to the anti-loosening ring, multiple pressure rods are slidably connected to the anti-loosening ring, one end of the pressure rod is fixedly connected to the fastening plate, the outer surface of the rotating shaft is threaded with a pressing rod, one end of the pressure rod is slidably connected to the pressing rod, and a return spring is sleeved on the outer surface of the pressure rod.

[0008] Preferably, the anti-loosening cylinder has multiple inlet holes at both ends, and multiple limiting rods are fixedly connected to the outer surface of the extrusion rod, with the limiting rods slidably connected to the anti-loosening cylinder.

[0009] Preferably, a fixed rod is slidably connected inside the shock absorber, one end of the fixed rod is disc-shaped, and a fixed plate is fixedly connected between multiple fixed rods, the fixed plate being fixedly connected to the detection box.

[0010] Preferably, a placement box is fixedly connected to the base, and an extrusion plate is slidably connected inside the placement box. The extrusion plate is fixedly connected to the fixed plate.

[0011] Preferably, the placement box is equipped with a rubber airbag, the rubber airbag is fixedly connected to the extrusion plate, and the rubber airbag is fixedly connected to a nozzle.

[0012] Preferably, two stabilizing boxes are fixedly connected to the base, each stabilizing box has a sliding rod inside, and a connecting plate is slidably connected to the outer surface of the sliding rod. The detection box is fixedly connected between the two connecting plates.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The wiring between the fastening plate and the placement plate is fixed by the cooperation of components such as the rotating shaft, anti-loosening ring, and clamping rod. This allows the wiring to move synchronously with the test box when there is external vibration, without relative movement. This ensures that the wiring joints and the interfaces inside the test box are not affected by external vibration, improves the stability of the wiring and the test box, and allows the test box to work for a long time, reducing the number of maintenance operations.

[0015] 2. The shock absorber, shock spring, and fixing rod work together to absorb and mitigate some of the external vibrations. The sliding rod, stabilizing box, and connecting plate work together to further mitigate some of the external vibrations, ensuring that only minor vibrations are transmitted into the test chamber and guaranteeing the stability of the test chamber.

[0016] 3. Through the combined action of components such as the fixing plate, the extrusion plate, and the nozzle, the gas inside the rubber airbag acts on the heat dissipation plate of the testing chamber, blowing off the dust accumulated on the heat dissipation plate. This prevents the dust from clogging the heat dissipation vents on the heat dissipation plate, thus affecting the heat dissipation performance of the testing chamber, improving the air circulation between the testing chamber and the outside environment, and thereby improving the stability of the heat dissipation function of the testing chamber.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0025] Reference Figure 1 A railway signal receiving and detection device includes a base 1 and a detection box 7. The base 1 is fixed to the ground, and the detection box 7 is equipped with multiple electronic components for receiving and detecting signals. Multiple shock-absorbing cylinders 2 are fixedly connected to the base 1.

[0026] Reference Figure 4-5 The testing box 7 is equipped with anti-loosening components, including an anti-loosening cylinder 11, a rotating shaft 12, an anti-loosening ring 13, a placement plate 14, a fastening plate 15, a pressure rod 16, and a squeezing rod 18. The anti-loosening cylinder 11 is fixedly connected to the testing box 7. Multiple wire inlet holes are opened at both ends of the anti-loosening cylinder 11. The rotating shaft 12 is rotatably connected inside the anti-loosening cylinder 11. A rotating disk is provided at one end of the rotating shaft 12 that passes through the anti-loosening cylinder 11 for easy rotation by workers. The anti-loosening ring 13 is fixedly connected inside the anti-loosening cylinder 11. The anti-loosening ring 13 has round holes corresponding to the wire inlet holes. Figure 5As shown, multiple placement plates 14 are fixedly connected to anti-loosening rings 13. The placement plates 14 are fixed inside the circular holes. Multiple pressure rods 16 are slidably connected to anti-loosening rings 13. One end of the pressure rod 16 passing through the circular hole is fixedly connected to a fastening plate 15. One end of the pressure rod 16 is fixedly connected to the fastening plate 15. Both the fastening plate 15 and the placement plates 14 are arc-shaped. A pressing rod 18 is threadedly connected to the outer surface of the rotating shaft 12. The end of the pressing rod 18 near the pressure rod 16 is spherical. One end of the pressure rod 16 is slidably connected to the pressing rod 18. The radius of the spherical end of the pressure rod 16 is smaller than the radius of the sphere of the pressing rod 18. A return spring 17 is sleeved on the outer surface of the pressure rod 16. Multiple limiting rods 19 are fixedly connected to the outer surface of the pressing rod 18. The limiting rods 19 are slidably connected to the anti-loosening cylinder 11. The function of the limiting rods 19 is to ensure that the pressing rod 18 can only move linearly and will not rotate.

[0027] Reference Figure 2 A fixed rod 3 is slidably connected inside the shock absorber 2. One end of the fixed rod 3 is disc-shaped. A shock-absorbing spring is provided between the fixed rod 3 and the inner wall of the shock absorber 2. A fixed plate 4 is fixedly connected between multiple fixed rods 3. The fixed plate 4 is fixedly connected to the test box 7. A placement box 8 is fixedly connected to the base 1. A pressing plate 9 is slidably connected inside the placement box 8. The pressing plate 9 is fixedly connected to the fixed plate 4. Two stabilizing boxes 5 are fixedly connected to the base 1. A sliding rod is provided inside the stabilizing box 5. The outer surface of the sliding rod is smooth and has low friction. A connecting plate 6 is slidably connected to the outer surface of the sliding rod. The test box 7 is fixedly connected between the two connecting plates 6. A heat dissipation plate is provided on the outer surface of the test box 7. Multiple heat dissipation holes are opened on the heat dissipation plate to connect the inside of the test box 7 with the outside air.

[0028] Reference Figure 3 The placement box 8 is equipped with a rubber airbag. The rubber airbag has good elasticity and repositioning properties, which can absorb some of the vibration. At the same time, it contains a certain amount of gas. The rubber airbag is fixedly connected to the extrusion plate 9. The rubber airbag is fixedly connected to the nozzle 10, which has multiple tiny air holes.

[0029] In this invention, by rotating the shaft 12, the rotation of the shaft 12 causes the pressing rod 18 to move outward. At this time, the pressure rod 16 is not subjected to the pressing action of the pressing rod 18. Under the action of the return spring 17, the fastening plate 15 moves to the center. At this time, there is a large space between the fastening plate 15 and the placement plate 14. The wire that needs to be placed into the test box 7 passes through the anti-loosening cylinder 11 and the anti-loosening ring 13. At this time, one section of the wire is between the fastening plate 15 and the placement plate 14. By rotating the shaft 12, the rotation of the shaft 12 causes the pressing rod 18 to move towards the pressure rod 16. The pressure rod 16 is subjected to the pressing action of the pressing rod 18, causing the fastening plate 15 to move towards the placement plate 14 until the wire between the two is fixed. External vibrations will cause the wire and the test box 7 to move synchronously without relative movement, ensuring that the wire joint and the interface inside the test box 7 are not affected by external vibrations, improving the stability of the wire and the test box 7, ensuring that the test box 7 can work for a long time and reducing the number of maintenance.

[0030] When the base 1 is vibrated, the vibration is absorbed and mitigated by the damping spring in the damping cylinder 2 and the fixed rod 3. Only a small vibration is transmitted to the test box 7. When the test box 7 is affected by vibration, it moves slightly up and down under the action of the connecting plate 6. Under the action of the stabilizing box 5, the stability of the test box 7 is ensured, further mitigating the external vibration and ensuring that only a small vibration is transmitted to the inside of the test box 7.

[0031] When the testing box 7 moves slightly, it causes the fixing plate 4 to move up and down continuously. The movement of the fixing plate 4 causes the squeezing plate 9 to squeeze the rubber airbag placed inside the box 8. The squeezing action of the squeezing plate 9 forces the internal gas of the rubber airbag to act on the heat dissipation plate of the testing box 7 through the nozzle 10, blowing off the dust accumulated on the heat dissipation plate and preventing the dust from blocking the heat dissipation vents on the heat dissipation plate and affecting the heat dissipation performance of the testing box 7. This improves the air circulation between the testing box 7 and the outside environment, thereby improving the stability of the heat dissipation function of the testing box 7.

[0032] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
