Description

Technical Field

[0001] The utility model belongs to the technical field of train safety anti-skid technology, in particular to an intelligent anti-skid iron shoe capable of local indication. Background Art

[0002] With the continuous development of my country's railway system, the safety of railway train stations is directly related to the normal operation of the railway system. Anti-slip iron shoes have become an important device for protecting the safety of personnel and vehicles. Traditional anti-slip iron shoes have a simple structure and a single function. Their placement and removal are completed by operators on-site. There is a lack of unified monitoring and management, and the placement status of the iron shoes cannot be detected in real time. If communication, inspection, and confirmation are incomplete during the operation, and the handover is not in place, problems such as missing or missing iron shoes, or improper placement of iron shoes will occur, which can easily lead to major safety accidents such as train skidding, derailment, and driving with shoes on. Traditional intelligent iron shoes use ultrasonic sensors to detect the placement status of iron shoes. Due to the fact that ultrasonic waves are greatly affected by temperature and have measurement dead zones, they often lead to misjudgment of the status.

[0003] Therefore, a utility model is designed to provide a smart anti-slip iron shoe with local indication, which integrates an iron shoe placement status detection device, a status indication circuit, and a smart box. It is used to accurately judge the placement status of the smart anti-slip iron shoe, display the anti-slip status on site, and receive and upload the anti-slip status information through the smart box to solve the safety hazards in the anti-slip operation of the site and improve the anti-slip operation efficiency of the site. Utility Model Content

[0004] The technical problem to be solved by the present invention is to address the deficiencies in the above-mentioned prior art and provide an intelligent anti-slip iron shoe with an iron shoe placement status detection device. The device has a simple structure and a reasonable design. Through the cooperation of a push rod mechanism, a spring device, and a contact conductive spring, it can effectively judge whether the train wheel is close to the iron shoe and detect the placement status of the iron shoe. The contact closing / opening signal of the contact conductive spring is uploaded to the monitoring host computer through the intelligent box, which facilitates unified monitoring and management of train stations.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: an intelligent anti-slip iron shoe with an iron shoe placement status detection device, including a shoe body, an iron shoe placement status detection device, a status indication circuit, and an intelligent box. The shoe body includes a shoe body, a sole for being placed on the track, and a skirt under the sole for fixing the iron shoe on the track. The interior of the shoe body is used to install the intelligent box and the iron shoe placement status detection device, and the shoe body is provided with a curved front baffle for fitting the train wheels.

[0006] The train wheel status detection device includes a push rod mechanism, a spring device, and a contact conductive spring. The contact conductive spring is fixed to the bottom of the push rod mechanism. Contacts are provided at the bottom of both ends of the contact conductive spring. The contacts move with the push rod mechanism to achieve contact or separation with the contact components in the status indication circuit, thereby connecting or disconnecting the status indication circuit.

[0007] The push rod mechanism includes a support column and a top support, and the top support is fixed on the support column; the top support protrudes from the front baffle of the curved surface of the shoe body, and the bottom end of the support column is installed with a contact conductive spring and connected to a spring device; the bottom end of the spring device is fixed inside the shoe body, and its top end is connected to the contact conductive spring.

[0008] In the above-mentioned intelligent anti-skid shoe, the state indication circuit includes a battery, a contact component, a light-emitting diode, a resistor, and a state level terminal. The negative electrode of the battery and the negative electrode of the power supply of the intelligent box are connected to a common ground through a power line.

[0009] In the aforementioned intelligent anti-skid shoe, when the shoe body is not in contact with the wheel, the push rod mechanism, under the elastic force of the spring device, causes the contact conductive spring at the end of the push rod mechanism to move away from the contact component of the status indication circuit, disconnecting the status indication circuit, turning off the LED, and the smart box detecting that the status level terminal is at the bottom, outputting that the new intelligent anti-skid shoe is in the "false anti-skid" state. When the train wheel approaches, the push rod mechanism, pushed by the wheel, pushes the spring device, causing the spring device to enter a compressed state. As the push rod mechanism moves, the contact conductive spring presses the contact component of the status indication circuit, closing the status indication circuit, turning on the LED, and the smart box detecting that the status level terminal is at the bottom, outputting that the new intelligent anti-skid shoe is in the "anti-skid" state. When the wheel leaves, the push rod mechanism recovers under the elastic force of the spring device.

[0010] In the above-mentioned intelligent anti-slip iron shoes, the push rod mechanism and the spring device are perpendicular to the curved surface of the shoe body, and the light-emitting diode of the status indication circuit is installed on the side of the bottom of the shoe body.

[0011] In the above-mentioned intelligent anti-slip iron shoe, the state level terminal is connected to the smart box through a signal line for it to detect high and low level states. The smart box can be implemented using a single-chip microcomputer or other embedded systems.

[0012] Beneficial effects

[0013] The utility model adopts the above technical means, and has the following beneficial effects compared with the prior art:

[0014] The utility model has the advantages of simple structure, reasonable design, stability, reliability, and simple and convenient operation.

[0015] The utility model connects or disconnects the anti-slip state indicating circuit through a push rod mechanism, a spring device and a contact conductive spring. The on-site indicator light directly indicates whether the iron shoe is in the "anti-slip" state.

[0016] This new technology applies a travel switch to the intelligent anti-skid shoe. Through the push rod mechanism, spring device, contact conductive spring, and anti-skid status indication circuit, it can effectively determine whether the intelligent anti-skid shoe is placed against the wheel, detect the placement status of the intelligent anti-skid shoe, and upload the anti-skid information to the station monitoring host computer through the smart box, realize unified monitoring and management, and reduce the management pressure of the anti-skid shoes of the entire station on the train station.

[0017] The utility model fixes the intelligent anti-slip iron shoe on the track through the skirt, effectively preventing the iron shoe from sliding and shifting on the track, and improving the reliability of the anti-slip iron shoe. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] like Figure 1 As shown, the utility model includes a shoe body and an iron shoe placement status detection device, the shoe body includes a shoe body 1, a sole 2 for being placed on a track, and a skirt 3 under the sole for fixing the iron shoe on the track, the interior of the shoe body is used to install a smart box 8 and an iron shoe placement status detection device, and the shoe body is provided with an arc front baffle 4 for fitting the train wheels. The iron shoe placement status detection device includes a contact conductive spring 5, a push rod mechanism 6, and a spring device 7. The contact conductive spring 5 is fixed to the bottom of the push rod mechanism 6, and the contacts at both ends thereof move with the push rod mechanism to connect or disconnect the status indication circuit. One end of the push rod mechanism 6 protrudes from the arc front baffle 4 of the shoe body, and the other end is provided with a contact conductive spring 5 and is connected to the spring device 7. The bottom end of the spring device 7 is fixed to the inside of the shoe body, and the top end is connected to the contact conductive spring 5.

[0023] The state indication circuit includes a light-emitting diode 9 (preferably a green LED), a battery 10 (preferably two 3V button batteries), a contact component 11, a resistor 12 (preferably a 400Ω carbon film resistor), and a state level terminal 13. The negative electrode of the battery and the negative electrode of the smart box power supply are connected to a common ground via a power line.

[0024] During implementation, staff insert the front end of the sole 2 under the train wheel and secure the shoe to the track using the skirt 3. When the shoe is not in contact with the wheel, the spring device 7 exerts a force on the push rod mechanism 6, causing the contact conductive spring 5 at the end of the push rod mechanism 6 to move away from the contact component 11 of the status indication circuit. This disconnects the status indication circuit, turning off the LED 9. The smart box 8 detects that the status level terminal 13 is at a low level and outputs that the new intelligent anti-skid shoe is in a "false anti-skid" state. When the train wheel approaches, the push rod mechanism 6, pushed by the wheel, pushes the spring device 7, causing it to enter a compressed state. As the push rod mechanism moves, the contact conductive spring 5 presses against the contact component 11 of the status indication circuit, closing the status indication circuit and turning on the LED 9. The smart box 8 detects that the status level terminal is at a low level and outputs that the new intelligent anti-skid shoe is in a "false anti-skid" state. When the wheel moves away, the push rod mechanism 6 returns to its original position under the force of the spring device 7.

[0025] The push rod mechanism 6 and spring device 7 are perpendicular to the curved surface of the shoe body. The LED 9 of the status indication circuit is installed on the side of the bottom of the shoe body. The status level terminal 13 is connected to the smart box via a signal line for detecting high and low level states. The smart box 8 can be implemented using a single-chip microcomputer (preferably STC8051) or other embedded system (preferably STM32F103).
