Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically to a device for checking the interlocking relationship between rail transit signal and turnout. Background Technology

[0002] In rail transit systems, the interlocking relationship between signals and switches is a core element in ensuring train operation safety. Signals indicate the train's running status, while switches guide trains to change tracks. The interlocking relationship ensures that when a switch is not in a safe position, the signal will not display a permission signal, preventing the train from accidentally entering the wrong track and causing an accident.

[0003] In the interlocking detection of turnout status and signal, although the data can be processed and transmitted through the detection controller, in order to ensure the accuracy of the detection controller, it is necessary to maintain the detection controller regularly. However, the existing detection controllers are often installed on the signal by means of pasting, which makes it inconvenient to disassemble and maintain them regularly. Utility Model Content

[0041] 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.

[0042] like Figures 1 to 5 As shown, this utility model provides a device for checking the interlocking relationship between a rail transit signal and a turnout, comprising:

[0043] The housing 1 has a receiving cavity, and the housing 1 is formed by combining a front housing and a rear housing;

[0044] The electronic control components are installed inside the accommodating cavity;

[0045] The mounting mechanism 2 has a locked state and an unlocked state. The mounting mechanism 2 includes a first mounting base 21 and a second mounting base 22. The first mounting base 21 is used to mount on the signal, and the second mounting base 22 is connected to the rear housing. The first mounting base 21 has a first adjusting head, and the second mounting base 22 has a second adjusting head that cooperates with the first adjusting head.

[0046] When the mounting mechanism 2 is in the locked state, the first adjusting head and the second adjusting head are in contact, so that the second mounting base 22 is fixed to the first mounting base 21;

[0047] When the mounting mechanism 2 is in the unlocked state, the second adjusting head can move relative to the second adjusting head so that the second mounting seat 22 can disengage from the first mounting seat 21.

[0048] In this embodiment, by installing the first mounting base 21 on the signal machine and installing the second mounting base 22 on the rear housing, since the first mounting base 21 has a first adjusting head and the second mounting base 22 has a second adjusting head, the first adjusting head and the second adjusting head cooperate to enable the second mounting base 22 to be quickly fixedly connected to or quickly detached from the first mounting base 21, thereby enabling the housing 1 with the electronic control components installed to be quickly removed from the signal machine or quickly replaced and installed on the signal machine for subsequent maintenance.

[0049] Meanwhile, by fitting the upper and rear shells together and installing the electronic control components inside the cavity, the stability of the device during use is ensured, and damage to the electronic control components caused by changes in the external environment (such as storms, scorching sun, etc.) is avoided. The internal electronic control components are also protected from dust, water, and sun, thus extending their service life.

[0050] like Figures 1 to 5 As shown, in one embodiment, the first adjusting head has a sleeve portion 211 for mounting the second adjusting head, and the first mounting base 21 is also provided with an adjusting member 212, which is used to adjust the size of the sleeve portion 211 so that the sleeve portion 211 is either far away from or close to the second adjusting head, so as to switch the mounting mechanism 2 to the unlocked state or the locked state.

[0051] In this embodiment, the sleeve portion 211 and the adjusting member 212 are used in conjunction to achieve the effect of quick assembly and disassembly of the first mounting base 21 and the second mounting base 22. The adjusting member 212 can be a screw.

[0052] Specifically, the outer surface of the second adjusting head is hemispherical, and the outer surface of the second adjusting member 212 is arrayed with several limiting strips 221; the sleeve portion 211 of the first adjusting head is provided with a limiting portion 213, and the adjusting member 212 is installed at the limiting portion 213 to facilitate the adjustment of the size of the limiting portion 213, thereby causing the size of the sleeve portion 211 to change. During installation, the second adjusting head is installed on the sleeve portion 211, and a corresponding limiting strip 221 can be installed into the limiting portion 213 as needed to ensure that the working angle of the housing 1 can be adjusted.

[0053] When the mounting mechanism 2 is switched to the locked state, since the limiting strip 221 is installed in the limiting part 213, the limiting part 213 is squeezed and limited by the adjusting member 212, thereby restricting the limiting strip 221 in the limiting part 213, thereby ensuring that the limiting part 213 can prevent the second adjusting head from rotating relative to the first adjusting head, and the sleeve part 211 can prevent the second adjusting head from moving relative to the first adjusting head, thereby preventing the first mounting base 21 from separating from the second mounting base 22;

[0054] When the mounting mechanism 2 is switched to the unlocked state, the adjusting member 212 releases the squeezing limit on the limiting part 213, so that the second adjusting head can rotate and move relative to the first adjusting head, thereby realizing the separation of the first mounting seat 21 from the second mounting seat 22.

[0055] like Figure 6 As shown, in one embodiment, the electronic control assembly includes an electronic control board, which includes:

[0056] The first transceiver module is used to send the positioning signal of the turnout when the turnout is in the positioning state or to send the reverse position signal of the turnout when the turnout is in the reverse position.

[0057] The second transceiver module is used to send the light status signals of the signal horn;

[0058] The control module is connected to the first transceiver module and the second transceiver module respectively, and is used to transmit the positioning signal or reverse position signal sent by the first transceiver module and the light status signal sent by the second transceiver module to the preset display panel for display.

[0059] In this embodiment, the first transceiver module, the second transceiver module, and the control module work together to transmit positioning signals or reverse position signals and light status signals to a preset display panel in real time. This reduces the workload of operators, provides an objective and accurate reflection of the on-site route conditions, and effectively prevents operational accidents. The preset display panel can be an indoor monitoring device, and the control module includes a microcontroller.

[0060] Depending on the requirements, the electronic control components may also include a power supply module to supply power to the device.

[0061] Depending on the requirements, the control board may also include a communication module, which connects to the control module to transmit positioning or reversal signals and lighting status signals to a preset display panel in real time. The communication module can employ NB-IoT network transmission circuitry, Bluetooth, Wireless Fidelity (Wi-Fi), ZigBee, LoRa, or other wireless transmission technologies.

[0062] like Figure 6 As shown, in one embodiment, the device further includes a first acquisition module connected to a first transceiver module. The first acquisition module is used to monitor the position status of the switch rail in real time, so as to acquire a positioning signal indicating that the switch is in a positioning state or a reversing signal indicating that the switch is in a reversing state in real time, and send it to the first transceiver module.

[0063] In one embodiment, the first acquisition module includes a displacement sensor installed on the switch rail. The displacement sensor is connected to the first transceiver module and is used to send an electrical signal of the actual displacement of the detected switch rail to the first transceiver module.

[0064] In one embodiment, the first acquisition module includes:

[0065] A positioning sensing unit is installed on one of the switch rails. The positioning sensing unit is connected to the first transceiver module and is used to send a positioning signal to the first transceiver module when the switch rail reaches the locking position.

[0066] The reverse position sensing unit is installed on the other switch rail of the turnout. The reverse position sensing unit is connected to the first transceiver module and is used to send a reverse position signal to the first transceiver module when the switch rail reaches the reverse locking position.

[0067] In one embodiment, the positioning sensing unit includes:

[0068] The first magnet is installed on the side of one of the switch rails;

[0069] The first proximity sensor is installed on the side of one of the main rails of the turnout. The first magnet is positioned opposite to the first proximity sensor. The first proximity sensor is connected to the first transceiver module.

[0070] When one of the switch rails reaches the locked position, the first magnet approaches or touches the first proximity sensor to generate a positioning signal and send it to the first transceiver module.

[0071] In one embodiment, the anti-position sensing unit includes:

[0072] The second magnet is installed on the side of the other switch rail;

[0073] The second proximity sensor is installed on the side of another main rail of the turnout. The second magnet is positioned opposite to the second proximity sensor. The second proximity sensor is connected to the first transceiver module.

[0074] When the other switch rail reaches the reverse locking position, the second magnet approaches or touches the second proximity sensor to generate a reverse signal and send it to the first transceiver module.

[0075] like Figure 6 As shown, in one embodiment, the device further includes a second acquisition module connected to a second transceiver module. The second acquisition module is used to acquire the light status signals of each signal light of the signal machine in real time and send the light status signals to the second transceiver module.

[0076] In one embodiment, the second acquisition module includes multiple light sensors, each of which is configured to correspond one-to-one with a signal light of the traffic signal.

[0077] The light sensor is installed under the eaves of the traffic light to improve detection accuracy, and the eaves can effectively protect the light sensor.

[0078] By using the various modules of the electrical control component of this utility model in conjunction with the first acquisition module and the second acquisition module, it can effectively solve the problems in the traditional signal and turnout interlocking relationship, which is caused by the reliance on manual periodic inspection or decentralized electrical detection modules, resulting in low inspection efficiency, poor real-time performance, and easy omissions and false detections; the inspection process relies on manual experience and has a low degree of standardization; and it is difficult to achieve automated and visualized detection of complex interlocking relationships.

[0079] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it is obvious that many changes and variations can be made based on the above teachings.
