[0001] This utility model relates to the technical field of devices for measuring the clearance of signal machines, specifically a device for measuring the clearance of signal machines. Background Technology
[0002] A traffic signal is a device used to control and manage traffic flow. It is mainly used in transportation systems such as railways, highways, and urban rail transit to ensure transportation safety and efficiency.
[0003] Measuring signal clearance is to ensure that the installation position, display range, and mechanical structure of the signal do not intrude into the dynamic or static clearance of the railway or road, thereby ensuring traffic safety and normal equipment operation.
[0004] Most existing devices for measuring signal clearance adopt fixed structures, such as large brackets or integrated detection platforms, which are bulky, difficult to disassemble, and inconvenient to transport and store. Traditional manual measuring tools are inefficient, scattered, and difficult to manage. Therefore, we propose a device for measuring signal clearance. Utility Model Content
[0005] One of the technical problems that this application aims to solve is that most existing measuring signal limit devices adopt a fixed structure, such as a large bracket or integrated detection platform, which is bulky, difficult to disassemble, inconvenient to transport and store, and traditional manual measuring tools are inefficient, scattered and difficult to manage.
[0006] To address the aforementioned technical problems, this application provides a device for measuring the clearance of a signal controller, comprising a detection plate and a counterweight plate. A clearance measuring component is disposed on the top of the detection plate, and a tilt sensor is disposed at one end of the clearance measuring component. A fixing plate is disposed at one end of the detection plate, and sliding rods are symmetrically disposed between the fixing plate and the counterweight plate. A sliding sleeve is slidably sleeved on the outside of the sliding rod, and a connecting plate is disposed on the surface of the sliding sleeve. A traveling wheel is disposed on the side of the connecting plate.
[0007] In some embodiments, a displacement detector is provided at one bottom end of the detection plate, a handle extends outward from the front end of the detection plate, both ends of the detection plate are movably connected to the side of the fixed plate via a rotating shaft, balance wheels are provided at both ends of the counterweight plate, and a slot is provided in the middle of the counterweight plate.
[0008] In some embodiments, a connecting block is provided on the top of the detection plate, a push rod is movably connected inside the connecting block, a push plate is provided at one end of the push rod, and a first pull rod and a second pull rod are movably connected inside the push plate via a shaft, with one end of the first pull rod and the second pull rod engaging with each other.
[0009] In some embodiments, the first pull rod and the second pull rod are symmetrically arranged about the push plate and each has a connecting rod movably connected to one end, the connecting rod being movably connected to the top of the connecting plate.
[0010] In some embodiments, the detection plate and the fixing plate are connected by a pivot, the middle part of the fixing plate is recessed downward and flush with the bottom of the detection plate, and the handle and the slot are fitted together.
[0011] In some embodiments, the end of the walking wheel near the connecting plate has a protrusion extending outwards, and the bottom of the balance wheel is flush with the bottom of the walking wheel without the protrusion.
[0012] This utility model has at least the following beneficial effects:
[0013] 1. This utility model raises the handle upwards, causing the push rod connected to the top of the handle via the connecting block to gradually move towards the counterweight plate. During the movement of the push rod, the angle between the first and second pull rods at both ends and the connecting rod changes. At the same time, the connecting rod is pulled towards the center, causing the connecting plate to rotate to a position parallel to the connecting rod. At this point, the connecting rod flips to the top of the device for storage, reducing the volume of the device during transportation and storage, reducing the time spent on installation and disassembly, and improving measurement efficiency.
[0014] 2. This utility model uses a handle at one end of the detection plate to be fixed inside the slot, which can reduce the overall size of the device. The balance wheels at both ends of the counterweight plate can improve the overall balance and stability of the device during movement under the counterweight effect of the counterweight plate, and improve the accuracy of the device when measuring the limit of the signal.

[0022] 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.
[0023] Example 1: Please refer to Figure 1-5 This utility model provides a technical solution: a device for measuring the clearance of a signal, comprising a detection plate 1 and a counterweight plate 6. A clearance measuring component 15 is provided on the top of the detection plate 1. A tilt sensor 3 is provided at one end of the clearance measuring component 15. A fixing plate 2 is provided at one end of the detection plate 1. Sliding rods 5 are symmetrically arranged between the fixing plate 2 and the counterweight plate 6. A sliding sleeve 7 is slidably sleeved on the outside of the sliding rod 5. A connecting plate 8 is provided on the surface of the sliding sleeve 7. A traveling wheel 9 is provided on the side of the connecting plate 8. The detection plate 1 and the fixing plate 2 are connected by a rotating shaft. The middle part of the fixing plate 2 is recessed downward and flush with the bottom of the detection plate 1. The handle 101 and the slot 601 are interlocked. The clearance measuring component 15 quickly measures the real-time distance between the signal and the track through a laser ranging module. The clearance measuring component 15 adopts visual recognition, acquiring images of the signal and the surrounding environment through a camera, and using an algorithm to identify its relative position with the clearance boundary. The tilt sensor 3, in conjunction with the lidar, monitors the signal angle deviation in real time, ensuring the accuracy of the measurement results and preventing misjudgments of the clearance due to equipment tilt. The sliding sleeve 7, under the pulling force of the connecting rod 10, drives the traveling wheel 9 to flip inward, allowing the traveling wheel 9 to flip to the top of the device for storage. The outward protrusion of the traveling wheel 9 allows it to be engaged between the rails, making the device's operation more stable. The clearance value of the signal edge from the center of the track varies depending on the line type and height. The clearance for main lines and oversized freight trains is 2440 mm; the clearance for ordinary station lines is 2150 mm; for curved sections, the car body offset needs to be considered and widened 2; the clearance for low-profile signals (height ≤ 1100 mm) is 1875 mm, and when running in the reverse direction, it needs to be ≥ 1800 mm and height ≤ 1250 mm 2; the clearance for passenger dedicated lines is uniformly 2440 mm, and only the impact of superelevation is considered for curved sections.
[0024] Please see Figure 1-3 A displacement detector 4 is provided at one bottom end of the detection plate 1. A handle 101 extends outward from the front end of the detection plate 1. Both ends of the detection plate 1 are movably connected to the side of the fixed plate 2 via a rotating shaft. Balance wheels 600 are provided at both ends of the counterweight plate 6. A slot 601 is provided in the middle of the counterweight plate 6. A protrusion is provided outward at the end of the traveling wheel 9 near the connecting plate 8. The bottom of the balance wheel 600 is flush with the bottom of the traveling wheel 9 without the protrusion. The displacement detector 4 is used to monitor the position change of the signal or its supporting structure in real time to ensure that the signal can still meet the clearance safety standards under long-term use or environmental factors. The counterweight plate 6 is used to maintain a constant weight at both ends of the device during the movement of the device and maintain the stability of the device during the movement.
[0025] Please see Figure 1-5 A connecting block 100 is provided on the top of the detection plate 1. A push rod 14 is movably connected inside the connecting block 100. A push plate 13 is provided at one end of the push rod 14. A first pull rod 11 and a second pull rod 12 are movably connected inside the push plate 13 via a shaft. One end of the first pull rod 11 and the second pull rod 12 are interlocked. The first pull rod 11 and the second pull rod 12 are symmetrically arranged about the push plate 13 and each end is movably connected to a connecting rod 10. The connecting rod 10 is movably connected to the top of the connecting plate 8. When the device needs to be stored, the handle 101 is raised, so that the push rod 14 connected to the top of the handle 101 via the connecting block 100 gradually moves closer to the counterweight plate 6. During the movement of the push rod 14, the angle between the first pull rod 11 and the second pull rod 12 at both ends and the connecting rod 10 will change. At the same time, the connecting rod 10 is pulled closer to the center, so that the connecting plate 8 rotates to a position parallel to the connecting rod 10, making the overall volume of the device smaller and easier to transport and store.
[0026] Example 2: Please refer to Figure 6 This utility model provides a technical solution: a device for measuring the clearance of a signal, including a detection plate 1 and a counterweight plate 6. A clearance measuring component 15 is provided on the top of the detection plate 1. An inclination sensor 3 is provided at one end of the clearance measuring component 15. A fixing plate 2 is provided at one end of the detection plate 1. A sliding rod 5 is symmetrically arranged between the fixing plate 2 and the counterweight plate 6. A sliding sleeve 7 is slidably sleeved on the outside of the sliding rod 5. A connecting plate 8 is provided on the surface of the sliding sleeve 7. A traveling wheel 9 is provided on the side of the connecting plate 8. A track gauge measuring frame 16 extends downward from the bottom end of the connecting plate 8. The track gauge measuring frame 16 can be used to assist in measuring the clearance of a signal, serving as the starting reference point for measuring the horizontal distance of the signal, ensuring a consistent benchmark during multiple measurements, and improving data comparability.
