Description

Technical Field

[0001] This invention relates to the field of track monitoring technology, and in particular to a detection control box with derailment monitoring function. Background Technology

[0002] Rail transport, with its advantages of large capacity, high efficiency, low energy consumption, and strong versatility, has become a core pillar of the transportation system and is widely used in key areas such as railway trunk line transport and urban rail transit. However, during long-term operation, rails must continuously withstand the impact of multiple complex factors such as train loads, wheel and rail wear, geological subsidence, temperature changes, and environmental erosion. The risk of derailment remains a core hidden danger threatening the safety of rail transport. As the core control unit of the derailment monitoring system, the detection control box undertakes important functions such as monitoring data acquisition, signal processing, command transmission, and equipment power supply. Its operational stability directly determines the effectiveness of derailment monitoring.

[0003] The electrical control module inside the electrical control box needs to achieve precise electrical connection with external sensors, transmission cables, power supply lines, etc. through wiring terminals. However, the continuous, high-frequency vibration generated during track operation becomes the main interference factor affecting the reliable operation of the electrical control box. The wiring terminals of existing electrical control boxes mostly use a single bolt fastening or a simple snap-on fixing structure, lacking a targeted anti-loosening design. Long-term track vibration will gradually weaken the connection strength between the terminal and the electrical post, leading to loose terminals, poor contact, or even detachment. This will cause monitoring signal interruption and data distortion, and in severe cases, cause the electrical control module to fail, making it impossible to capture derailment risk warning information in time. At the same time, the unlocking operation is prone to causing additional mechanical damage to the terminals or internal connecting components, and the reset accuracy after unlocking is insufficient, resulting in a decrease in connection stability when locking again, and the initial locking effect cannot be restored. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the background art, and to propose a detection electrical control box with derailment monitoring function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A detection control box with derailment monitoring function includes a box body and a door hinged to the front side of the box body. A bottom cover is fixedly installed on the bottom of the outer side of the box body. The bottom cover communicates with the bottom of the box body. An installation plate is fixedly installed inside the bottom cover. Multiple sets of anti-loosening terminal locking structures are provided between the installation plate and the bottom cover. The anti-loosening terminal locking structures position and lock the wiring terminals during installation to maintain the stability of the wiring under the long-term vibration of the track. The quick-unlocking mechanism, mounted on the bottom cover, is used for quick unlocking of the entire wiring terminal.

[0006] In the aforementioned detection electrical control box with derailment monitoring function, an electrical control module is installed inside the box, and the electrical control module performs electrical control through the connected wiring terminals.

[0007] In the aforementioned detection control box with derailment monitoring function, multiple power terminals are fixedly installed on the mounting plate, and the wiring terminals are inserted into the box body through the corresponding power terminals.

[0008] In the aforementioned detection control box with derailment monitoring function, the bottom cover has an installation groove and a through hole, and the installation groove and the through hole are connected.

[0009] In the aforementioned detection control box with derailment monitoring function, the anti-loosening terminal locking structure includes two fixed plates fixedly mounted on the mounting plate. Two rollers are rotatably mounted between the two fixed plates. One end of one of the rollers is fixedly mounted with a gear. A sliding hole is provided on the bottom cover, and the sliding hole is connected to the mounting groove. A toothed rod is slidably mounted in the sliding hole and meshes with the gear. A sliding groove is provided on one side of one of the fixed plates, and the toothed rod is slidably mounted in the sliding groove for use.

[0010] In the aforementioned detection control box with derailment monitoring function, teeth are provided at both the upper and lower ends of the rack. The spacing and size of the teeth at the upper end of the rack are greater than the spacing and size of the teeth at the lower end.

[0011] In the aforementioned detection control box with derailment monitoring function, two positioning plates are fixedly installed in the mounting slot. A rotating shaft is rotatably installed between the two positioning plates. A toothed ring and two lead screws are fixedly installed on the rotating shaft. The teeth of the toothed ring and the lower end of the toothed rods mesh with each other, and the grooves of the two lead screws are in opposite directions.

[0012] In the aforementioned detection control box with derailment monitoring function, cable clamps are threadedly installed on both lead screws, and the cable clamps are slidably disposed in the mounting groove. The positions of the two sets of cable clamps close to each other are arranged in an arc shape, and one end of each set of cable clamps is wedge-shaped. Two springs are fixedly disposed in the mounting groove, and one end of each of the two springs is fixedly installed with a wedge block. The two wedge blocks are used in conjunction with the wedge-shaped arrangement of the corresponding cable clamps.

[0013] In the aforementioned detection control box with derailment monitoring function, the quick unlocking structure includes a horizontal groove opened in the bottom cover, an unlocking plate slidably disposed in the horizontal groove, a guide block fixedly disposed on the lower surface of each wedge block, a displacement groove corresponding one-to-one with the two rows of guide blocks on the left side opened on the unlocking plate, and each guide block in the two rows on the left side slides in the corresponding displacement groove, the length of the displacement groove is greater than the length of the guide block, a plurality of displacement holes opened on the unlocking plate, and each toothed rod slides in the displacement hole.

[0014] In the above-mentioned detection control box with derailment monitoring function, a pin plate is fixedly installed on one side of the bottom cover, and multiple insertion holes are opened on the pin plate. A handle is fixedly installed on one side of the unlocking plate, and two insertion holes are opened near the handle on the unlocking plate. Each pair of insertion holes forms a group, and the two insertion holes are used alternately with the two groups of insertion holes. A pin is inserted between the two insertion holes and each group of insertion holes.

[0015] Compared with existing technologies, the advantages of this invention are as follows: the detection control box with derailment monitoring function can effectively adapt to the track vibration environment through a dual anti-loosening mechanism, and avoid loosening of terminals and cables to ensure stable electrical connection; when the terminal is inserted, it can automatically trigger locking, and pulling the unlocking plate can realize overall synchronous unlocking, and the pin can prevent accidental contact, which simplifies the installation process and avoids the decrease in accuracy caused by repeated operation, ultimately greatly improving the operational stability and installation and maintenance efficiency of the derailment monitoring system.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Reference Figures 1-6 A detection control box with derailment monitoring function includes a box body 2 and a door 1 hinged to the front of the box body 2. An electrical control module 4 is installed inside the box body 2. The electrical control module 4 is electrically controlled via connected terminals. A bottom cover 3 is fixedly installed on the bottom of the outer side of the box body 2, communicating with the bottom of the box body 2. A mounting plate 5 is fixedly installed inside the bottom cover 3, and multiple power connection posts 8 are fixedly installed on the mounting plate 5. The terminals are inserted into the box body 2 through the corresponding power connection posts 8. This design achieves precise connection between the terminals and the electrical control module 4 through the power connection posts 8, laying the foundation for stable transmission of subsequent electrical control signals. Simultaneously, the mounting plate 5 provides a stable mounting carrier for the power connection posts 8, ensuring sufficient support strength after the terminals are inserted, preventing misalignment due to external forces or vibrations. The power connection posts 8 provide an independent and orderly space for the installation and fixing of the terminals, avoiding tangling or wear caused by messy cable placement, and improving the neatness and safety of the internal structure.

[0020] The bottom cover 3 has a mounting groove 16 and a through hole 17, and the mounting groove 16 and the through hole 17 are connected. Multiple sets of anti-loosening terminal locking structures are provided between the mounting plate 5 and the bottom cover 3. The anti-loosening terminal locking structure includes two fixing plates 7 fixedly mounted on the mounting plate 5. Two rollers 6 are rotatably mounted between the two fixing plates 7. Both rollers 6 are provided with grooves. The grooves can increase the friction between the terminal and the rollers 6, so that the rollers 6 are rotated when the cable is inserted upward. One end of one of the rollers 6 is fixedly equipped with a gear 9. A sliding hole is provided on the bottom cover 3, and the sliding hole is connected to the mounting groove 16. A rack 10 is slidably arranged in the sliding hole and meshes with the gear 9. A groove is provided on one side of one of the fixing plates 7, and the rack 10 is slidably arranged in the groove. The two fixing plates 7 provide stable rotational support for the roller 6, ensuring that the roller 6 can rotate smoothly when subjected to force. The groove plays a limiting and guiding role in the sliding direction of the rack 10, preventing the rack 10 from deviating or jamming during movement, ensuring the meshing accuracy of the rack 10 and the gear 9, and thus ensuring the stability of power transmission.

[0021] The upper and lower ends of the rack 10 are both equipped with teeth. The spacing and size of the teeth at the upper end of the rack 10 are larger than those at the lower end. Two positioning plates 20 are fixedly installed in the mounting groove 16. A rotating shaft 24 is rotatably mounted between the two positioning plates 20. A gear ring 22 and two lead screws 23 are fixedly mounted on the rotating shaft 24. The gear ring 22 meshes with the teeth at the lower end of the rack 10, and the grooves of the two lead screws 23 are in opposite directions. When the large-sized, wide-spacing teeth at the upper end of the rack 10 mesh with the gear 9, they can withstand greater transmission torque, ensuring sufficient force when locking the terminal block and preventing insecure locking due to insufficient torque. When the small-sized, narrow-spacing teeth at the lower end mesh with the gear ring 22, more precise power transmission can be achieved, making the rotation angle of the rotating shaft 24 easier to control.

[0022] Cable clamps 18 are threaded onto both lead screws 23, and the cable clamps 18 are slidably disposed within the mounting groove 16. The two sets of cable clamps 18 are arranged in an arc shape when they approach each other. When the rotating shaft 24 drives the two lead screws 23 to rotate synchronously, the two sets of cable clamps 18 threaded onto the lead screws 23 can synchronously move closer or further apart, ensuring the cable is evenly clamped and preventing cable damage or loosening due to uneven clamping force. One end of each set of cable clamps 18 is wedge-shaped. Two springs 15 are fixedly disposed within the mounting groove 16, and a wedge block 19 is fixedly mounted on one end of each spring 15. Both wedge blocks 19 cooperate with the wedge-shaped arrangement of the corresponding cable clamp 18. The anti-loosening terminal locking structure positions and locks the terminal during installation, maintaining wiring stability under the long-term vibration of the track.

[0023] The arc design of the cable clamp 18 allows it to perfectly fit the outer surface of the cable, increasing the contact area and improving clamping stability while preventing damage to the cable insulation layer due to excessive local pressure. The wedge-shaped block 19 and the cable clamp 18, combined with the preload of the spring 15, form a reliable self-locking structure. When the cable clamp 18 moves towards the cable and completes clamping, the wedge block 19 presses tightly against the wedge-shaped surface of the cable clamp 18 under the action of the spring 15. Then, the spring 15 is squeezed, causing both sets of cable clamps 18 to move between the two wedge blocks 19. At the same time, the spring 15's rebound force causes the wedge blocks 19 to move and block the cable clamp 18 on both sides. Utilizing the self-locking characteristic of the wedge structure, the cable clamp 18 is prevented from reversing when subjected to vibration, ensuring a stable clamping state.

[0024] When the terminal block is inserted into the housing 2 through the terminal post 8, the insertion action of the terminal block will drive the two rollers 6 to rotate. The rollers 6 drive the gear 9 at one end to rotate synchronously. Since the gear 9 meshes with the teeth at the upper end of the rack 10, the rotation of the gear 9 will be converted into the rack 10 sliding vertically upward along the slide groove. When the rack 10 slides upward, the teeth at its lower end mesh with the gear ring 22, driving the gear ring 22 and the rotating shaft 24 to rotate synchronously. The rotating shaft 24 then drives the two lead screws 23 to rotate. Under the action of the lead screws 23 with opposite patterns, the two sets of cable clamps 18 move synchronously towards each other until the cable passing through the through hole 17 and entering the mounting groove 16 is firmly clamped. At this time, after the cable clamps 18 have completed clamping, the cable clamps 18 squeeze the spring 15 through the wedge block 19, so that both sets of cable clamps 18 move between the two wedge blocks 19. At the same time, under the rebound force of the spring 15, the wedge blocks 19 drive the cable clamps 18 to move and block the cable clamps 18 on both sides, thus completing the self-locking. The entire linkage process requires no additional power drive and can be triggered simply by inserting the terminal block, thus achieving cable locking. This simplifies the installation process, effectively resists the effects of long-term track vibration, solves the problem of loose terminal blocks and cables in traditional electrical control boxes, and ensures the continuous stability of the electrical connection between the electrical control module 4 and external equipment.

[0025] Reference Figures 5-7 It also includes a quick-unlocking structure, which is installed on the bottom cover 3 for quick unlocking of the entire wiring terminal. The quick-unlocking structure includes a horizontal groove opened in the bottom cover 3, in which an unlocking plate 21 is slidably disposed. A guide block is fixedly disposed on the lower surface of each wedge block 19. The unlocking plate 21 has displacement grooves 27 that correspond one-to-one with the two rows of guide blocks on the left side, and each guide block in the two rows on the left side slides in the corresponding displacement groove 27. The length of the displacement groove 27 is greater than the length of the guide block. The unlocking plate 21 has multiple displacement holes 26, and each toothed rod 10 has... Sliding within the displacement hole 26, the transverse groove provides a stable sliding guide for the unlocking plate 21, ensuring that the unlocking plate 21 can slide smoothly along a straight line; the design of the displacement groove 27 being longer than the guide block provides sufficient room for the guide block to move, preventing the guide block from getting stuck with the displacement groove 27 when the unlocking plate 21 slides, ensuring smooth unlocking action; the design of the displacement hole 26 allows the rack 10 to move freely up and down when the unlocking plate 21 slides, without being interfered with by the displacement of the unlocking plate 21, ensuring the independence and coordination of movement between the locking and unlocking structures.

[0026] A pin plate 13 is fixedly installed on one side of the bottom cover 3. The pin plate 13 has multiple insertion holes 12. A handle 14 is fixedly installed on one side of the unlocking plate 21. Two insertion holes 25 are opened on the unlocking plate 21 near the handle 14. Each pair of insertion holes 12 forms a group. The two insertion holes 25 are used alternately with the two groups of insertion holes 12. A pin 11 is inserted between the two insertion holes 25 and each group of insertion holes 12.

[0027] The handle 14 provides a convenient point of force for the operator, making the sliding operation of the unlocking plate 21 easier. The design of the pin 11 and the two sockets 12 and 25 reliably locks the position of the unlocking plate 21: when the device is in operation, the pin 11 is inserted into the two sockets 12 and 25 on the right side (near the bottom cover 3), fixing the unlocking plate 21 in the locked position, preventing the unlocking plate 21 from sliding due to accidental contact or vibration, and ensuring the stable locking state of the anti-loosening terminal locking structure; when unlocking is required, the pin 11 is pulled out and then the unlocking plate 21 is pulled outward from the bottom cover 3. 1. When the unlocking operation is performed, the unlocking plate 21 moves through the guide block with the cooperation of the displacement groove 27 and the guide block, causing each wedge block 19 to compress the spring 15. Then, the pin 11 is inserted into the two sockets 12 away from the bottom cover 3, and a downward pulling force is applied to the cable. At this time, the cable will drive the roller 6 to rotate in the opposite direction. According to the above operating principle, the two sets of cable clamps 18 are now far apart, ensuring the portability of the cable when it is reinstalled. At the same time, the alternating use of the two sets of sockets 12 can meet the dual fixing requirements of the unlocking plate 21 in the locked and unlocked positions, improving the safety and reliability of the equipment.

[0028] The entire unlocking process can be completed by pulling the unlocking plate 21, which simultaneously releases the self-locking of the wedge block 19 and triggers the unlocking action of the cable clamp 18 and roller 6. This achieves rapid unlocking of the terminals and cables as a whole, eliminating the need to unlock each terminal and cable individually. This greatly simplifies the maintenance process, saves maintenance time, and improves maintenance efficiency. At the same time, the linkage of each component during the unlocking process is smooth, which will not cause additional mechanical damage to the terminals, cables, or internal structures. After unlocking, each component can be accurately reset, and the initial locking effect can be restored when locking again, ensuring the stability of the equipment for long-term use.

[0029] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0030] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
