Description

Technical Field

[0001] This utility model relates to the field of rail transit equipment technology, and in particular to a rail transit signal relay status monitoring device. Background Technology

[0002] With the continuous expansion of urban rail transit networks and the sustained increase in operational density, the safety and reliability of rail transit signaling systems have become crucial concerns. Signal relays, as key components of rail transit signaling systems, undertake critical tasks such as control signal transmission, turnout switching, and track circuit control. The stability of their operational status directly determines whether the entire signaling system can accurately direct train operation. Failure of any relay can trigger signal anomalies, leading to serious consequences such as train delays, service stoppages, and even jeopardizing operational safety. Rail transit signal relay status monitoring devices are used to monitor the real-time operational status of relays in rail transit signaling systems. Relays play a vital role in rail transit signaling systems, such as controlling turnout switching and signal opening and closing, while monitoring devices can accurately detect the power supply, operating parameters, performance, and other aspects of the relays.

[0003] In the existing technology, traditional rail transit signal relay status monitoring devices are equipped with indicator lights. When the relay coil is energized and the contacts are closed, the indicator light lights up; when the coil is de-energized and the contacts are open, the indicator light goes out. By observing the on / off state of the indicator light, the working status of the relay can be judged to a certain extent.

[0004] However, in the existing technology, the installation of traditional relay status monitoring devices usually involves using a screwdriver to connect the device body to the outside of the rail transit lighting equipment with bolts or screws. This requires special tools and a large number of parts, making the installation cumbersome and inefficient. Therefore, a rail transit signal relay status monitoring device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a rail transit signal relay status monitoring device, which aims to improve the problem of low installation efficiency of monitoring devices in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A rail transit signal relay status monitoring device includes a housing. Two conduits are fixedly connected inside the housing. A spring is sleeved on the outside of each conduit. A sliding plate is slidably connected to the outside of each conduit. Two inclined plates are fixedly connected to one side of the sliding plate. Two sliding strips are fixedly connected to the rear side of the housing. A retaining plate is slidably connected inside each sliding strip. A connecting plate is fixedly connected to the outside of the retaining plate. A second spring is installed inside each sliding strip. Two sliding inclined strips are slidably connected inside the housing. A cable harness assembly for fixing input and output power lines is installed inside the housing.

[0008] As a further description of the above technical solution:

[0009] The outer side of the sliding plate is slidably connected to the inside of the housing, and the outer side of the inclined plate is slidably connected to the inside of the sliding strip.

[0010] As a further description of the above technical solution:

[0011] One end of the first spring is fixedly connected to the outside of the sliding plate, and the other end of the first spring is fixedly connected to the outside of the sliding plate. One end of the second spring is fixedly connected to the inside of the sliding bar, and the other end of the second spring is fixedly connected to the outside of the connecting plate.

[0012] As a further description of the above technical solution:

[0013] The outer surfaces of the two sliding slats are in contact with the outer surfaces of the sliding plates, and the outer surfaces of the two slats are in contact with the outer surfaces of the two clamping plates, respectively.

[0014] As a further description of the above technical solution:

[0015] The outer shell has multiple upper wiring screws connected to its external threads, and multiple lower wiring screws connected to its external threads. A power lamp is fixedly connected to the front side of the outer shell.

[0016] As a further description of the above technical solution:

[0017] The wire harness assembly includes multiple conduits, which are externally fixedly connected to the inside of the housing, and multiple U-shaped clips are slidably connected to the external surfaces of the multiple conduits.

[0018] As a further description of the above technical solution:

[0019] A spring three is fitted around the outside of the second conduit. One end of the spring three is fixedly connected to the inside of the outer shell, and the other end of the spring three is fixedly connected to the outside of the U-shaped clip.

[0020] As a further description of the above technical solution:

[0021] The U-shaped clip is externally slidably connected to the inside of the housing, and the U-shaped clip is used to fix the power cord to the outside of the housing.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, pressing the two sliding inclined bars causes the sliding plate to slide, thereby causing the inclined plate to slide and lose the squeezing force on the clamping plate. Then, the reaction force of the second spring causes the clamping plate to retract into the inside of the sliding bar. Then, the two sliding bars are slid into the inside of the traffic light. Releasing the two sliding inclined bars causes the sliding plate to slide back to its original position through the reaction force of the first spring. This causes the inclined plate to slide and squeeze the clamping plate out of the outside of the sliding bar, and it engages inside the traffic light, completing the quick installation and improving installation efficiency.

[0024] 2. In this utility model, by pulling up the U-shaped clip and sliding it inside the outer shell, the power cord is passed through the inside of the U-shaped clip and makes contact with the upper or lower wiring screw. Then, by releasing the U-shaped clip, the reaction force of the spring three drives the U-shaped clip to slide back to its original position, fixing the power cord to the outside of the outer shell, keeping the power cord stable and reducing the risk of it falling off.

[0032] 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.

[0033] Reference Figures 1 to 3 This utility model provides an embodiment of a rail transit signal relay status monitoring device, including a housing 1 made of robust plastic material, which can effectively resist external electromagnetic interference and ensure the stable operation of the internal electronic components. Two conduits 6 are fixedly connected inside the housing 1. The conduits 6 are cylindrical structures with polished exteriors, providing good insulation and a smooth outer wall. A spring 7 is fitted around the outside of the conduits 6. The spring 7 can reliably deform under external force and quickly return to its original shape after the force disappears, providing a reaction force. A sliding plate 8 is slidably connected to the outside of the conduits 6. The sliding plate 8 is a rectangular flat plate. Two inclined plates 10 are fixedly connected to one side of the sliding plate 8. The inclined plates 10 are rectangular in shape. Through the contact and compression of the inclined edges, the sliding direction of the subsequent structure is changed. The rear side of the housing 1 is fixedly connected to... Two sliding bars 5 are connected, and the sliding bars 5 are box-shaped, which are used to provide an installation base for the internal sliding engagement structure. The sliding bar 5 is slidably connected to a locking plate 11. One side of the locking plate 11 is also provided with a bevel. The locking plate 11 is slid out of the sliding bar 5 by the pressing contact of the bevel plate 10, and engages and fixes with the inside of the rail traffic light. The locking plate 11 is fixedly connected to a connecting plate 12, which is long and strip-shaped. The sliding of the locking plate 11 drives the connecting plate 12 to slide. The sliding bar 5 is provided with a spring 13, which is used to provide a reaction thrust to drive the connecting plate 12 and the locking plate 11 to slide and reset, thereby realizing the retraction and release of the engagement. The housing 1 is slidably connected to two sliding bevel bars 9. The sliding bevel bars 9 are used as a control structure. The sliding of the sliding plate 8 causes the sliding plate 8 to slide vertically. The housing 1 is provided with a cable tie assembly for fixing the input and output power lines.

[0034] Reference Figures 2 to 3The outer side of the sliding plate 8 is slidably connected to the inside of the outer casing 1. The sliding of the sliding plate 8 drives the inclined plate 10 to slide. The outer side of the inclined plate 10 is slidably connected to the inside of the sliding strip 5. The inside of the sliding strip 5 has a space to accommodate the sliding of the inclined plate 10 and to provide sliding guidance. One end of the spring 1 7 is fixedly connected to the outside of the sliding plate 8, and the other end of the spring 1 7 is fixedly connected to the outside of the sliding plate 8, thereby providing a reaction force to drive the sliding plate 8 to slide back to its original position, and to drive the inclined plate 10 to press the clamping plate 11 again. One end of the spring 2 13 is fixedly connected to the inside of the sliding strip 5, and the other end of the spring 2 13 is fixedly connected to the outside of the connecting plate 12, which is used to provide a reaction force to pull the clamping plate 11 back into the inside of the sliding strip 5, completing the retraction and facilitating disassembly. The outer sides of the two sliding inclined strips 9 are in contact with the outer side of the sliding plate 8. Through contact and compression, the sliding direction is changed, making it more convenient to operate. The outer sides of the two inclined plates 10 are in contact with the outer sides of the two clamping plates 11 respectively.

[0035] Reference Figure 1 , Figure 4 and Figure 5 The outer shell 1 has multiple upper wiring screws 3 and multiple lower wiring screws 4 connected to its external thread. The heads of the upper wiring screws 3 and lower wiring screws 4 are designed with an inner cross shape, which makes it convenient for operators to tighten or loosen them using special tools. A power light 2 is fixedly connected to the front of the outer shell 1. The light indicates whether the relay is energized by turning on or off, providing a monitoring effect for whether the relay can work properly.

[0036] Reference Figures 4 to 5 The cable harness assembly includes multiple conduits 14, which are externally fixed to the inside of the housing 1. The conduits 14 are made of hard plastic with excellent insulation properties and have a slender cylindrical structure, serving as a sliding guide. Multiple U-shaped clips 15 are slidably connected to the outside of the multiple conduits 14. The U-shaped clips 15 are U-shaped and are used to pass through and fix the power cord. A spring 16 is sleeved on the outside of the conduits 14. One end of the spring 16 is fixedly connected to the inside of the housing 1, and the other end of the spring 16 is fixedly connected to the outside of the U-shaped clips 15. The reaction force of the spring 16 drives the U-shaped clips 15 to slide in the opposite direction to fix the power cord. The outside of the U-shaped clips 15 is slidably connected to the inside of the housing 1, and the U-shaped clips 15 are used to fix the power cord to the outside of the housing 1.

[0037] Working principle: First, the operator slides the two sliding ramps 9 towards each other. The ramps cause the sliding plate 8 to slide inside the outer casing 1, compressing the spring 7 and generating force. The sliding plate 8 then causes the ramp 10 to slide inside the sliding strip 5, losing its pressure on the locking plate 11. The reaction force of the spring 13 then causes the locking plate 11 to slide in the opposite direction, returning to its original position inside the sliding strip 5. Finally, the device is placed outside the traffic light, and the two sliding strips 5 are slid into the traffic light. The two sliding ramps 9 are then released. The reaction force of the spring 7 causes the sliding plate 8 to slide back to its original position, causing the ramp 10 to slide and compress the locking plate 11, which then slides out of the sliding strip 5 and engages inside the traffic light, completing the quick installation. The operator only needs to press the sliding ramps 9 and perform simple sliding operations, without the need for complex tools or professional skills, to efficiently complete the installation, greatly saving installation time and labor costs and improving installation efficiency.

[0038] Secondly, when using the relay, connect the device to the relay via the power cord and the upper wiring screw 3 and lower wiring screw 4. Detect the power supply by checking if the power indicator 2 is lit. When installing the power cord, there is a possibility of it falling off due to vibration caused by external factors. In this case, pull up the U-shaped clip 15 and slide it inside the housing 1. Pass the power cord through the inside of the U-shaped clip 15 and make contact with the upper wiring screw 3 or lower wiring screw 4. Then release the U-shaped clip 15. The reaction force of the spring 16 will cause the U-shaped clip 15 to slide back to its original position, fixing the power cord to the outside of the housing 1, keeping the power cord stable and reducing the risk of it falling off.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
