Description

Technical Field

[0001] This invention mainly relates to the field of rail vehicle technology, specifically to a device for detecting the temperature of brake shoes on railway vehicles. Background Technology

[0002] Tread braking is one of the main braking methods for railway vehicles. In tread braking, the friction between the brake shoes and the wheel tread is the form in which the vehicle's braking force is generated. However, the friction between the brake shoes and the wheel tread generates...

[0003] The heat generated is significant. Even with high-performance synthetic brake shoes, the temperature can still reach 400℃ to 500℃ under high-load braking. High temperatures can lead to melting and peeling of the brake shoe material, among other malfunctions.

[0004] It has an adverse effect on the performance of the vehicle's braking system.

[0005] Monitoring the temperature of the brake shoes is therefore quite necessary. Currently, there are devices for monitoring the temperature of bogie wheels, either installed near the track on the ground or on the vehicle itself, but these devices...

[0006] Based on the principle of infrared temperature detection, the accuracy of infrared temperature measurement decreases significantly in environments with high levels of pollution such as dust and mud. Another method for detecting brake shoe temperature involves drilling holes in the brake shoe to accommodate...

[0007] Temperature sensors are available, but the need for custom brake shoes and the frequent replacement of brake shoes pose a significant obstacle.

[0008] Therefore, in order to solve the problems of existing brake shoe temperature measurement and infrared thermometry, the present invention provides a railway vehicle brake shoe temperature detection device to overcome the above-mentioned drawbacks. Summary of the Invention

[0009] The purpose of this invention is to provide a railway vehicle brake shoe temperature detection device, which solves the technical problems of brake shoe temperature measurement and infrared thermometry in the prior art.

[0010] This invention discloses a railway vehicle brake shoe temperature detection device, including a constant contact mechanism, which is fixedly connected to the brake shoe support, and a temperature sensor is connected to the constant contact mechanism, which is movably mounted on the constant contact mechanism.

[0011] By fixing the constant contact mechanism to the brake shoe support, a support can be provided for the temperature sensor, ensuring that the temperature sensor can measure the brake shoe temperature. The temperature sensor follows the movement of the brake shoe support and is not affected by changes in the brake shoe position due to wheel wear. By attaching the temperature sensor to the constant contact mechanism...

[0012] The automatic setting allows for brake shoe replacement simply by moving the temperature sensor, solving the technical problem of unstable temperature measurement during frequent brake shoe replacements in existing technologies, and greatly reducing the need for brake shoe replacement.

[0013] Reduce the probability of damaging the temperature sensor during brake shoe removal and installation.

[0014] Furthermore, the constant contact mechanism includes a bracket and a connecting seat, the temperature sensor is disposed on the bracket, the connecting seat is movably connected to the bracket, and the connecting seat is fixedly connected to the brake shoe holder.

[0015] 0 By setting a connecting seat, the connecting seat and the brake shoe support are kept fixed, and the bracket can rotate around the connecting seat.

[0016] Furthermore, the bracket has a U-shaped structure, with one end connected to the temperature sensor and the other end provided with a guide slope.

[0017] By setting a guide ramp that extends into the brake shoe holder, the temperature sensor contacts the brake shoe under the action of the bracket when the brake shoe pin contacts the guide ramp, making installation convenient.

[0018] Furthermore, the connecting seat and the bracket are provided with corresponding pin holes, a pin is provided in the pin hole, and a torsion spring is provided on the pin.

[0019] By setting a torsion spring, when the brake shoe pin separates from the guide ramp, the bracket rotates under the drive of the torsion spring, and moves the temperature sensor away from the brake shoe.

[0020] Furthermore, the number of torsion springs is two.

[0021] Furthermore, a sleeve is provided on the pin between the torsion spring and the connecting seat.

[0022] By installing a sleeve, the support can be prevented from shifting vertically on the connector, thus avoiding interference with temperature detection.

[0023] Furthermore, the number of sleeves is two.

[0024] 5. Furthermore, the temperature sensor is connected to a demodulation analyzer.

[0025] By connecting the temperature sensor to the demodulation analyzer, the temperature signal can be transmitted to the demodulation analyzer. After being processed by the data conditioning and analysis module of the demodulation analyzer, the temperature data is then sent to the communication module.

[0026] Furthermore, the temperature sensor is connected to the demodulation analyzer via a wired connection.

[0027] Setting up a wired connection improves stability.

[0028] Furthermore, the temperature sensor is connected to the demodulation analyzer wirelessly.

[0029] Furthermore, the demodulation analyzer includes a power module, a data demodulation and analysis module, and a communication module.

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] 1. By fixing the constant contact mechanism to the brake shoe support, the temperature sensor can be supported, ensuring that the temperature sensor can measure the brake shoe temperature. The temperature sensor follows the movement of the brake shoe support and is not affected by the change in brake shoe position due to wheel wear.

[0032] 2. By moving the temperature sensor on the constant contact mechanism, when the brake shoe needs to be replaced, the brake shoe can be replaced simply by moving the temperature sensor. This solves the technical problem in the prior art where frequent replacement of brake shoes makes it impossible to stably measure the temperature, and greatly reduces the probability of damage to the temperature sensor caused by the disassembly and assembly of the brake shoe.

[0033] 3. By setting a connecting seat, the connecting seat and the brake shoe support are kept fixed, and the bracket can rotate around the connecting seat;

[0034] 4. By setting a guide ramp that extends into the brake shoe holder, when the brake shoe pin contacts the guide ramp, the temperature sensor contacts the brake shoe under the action of the bracket, making installation convenient;

[0035] 5. By setting a torsion spring, when the brake shoe pin separates from the guide slope, the bracket rotates under the drive of the torsion spring, and drives the temperature sensor away from the brake shoe;

[0036] 6. By installing a sleeve, the vertical displacement of the bracket on the connector can be prevented, which would affect temperature detection;

[0037] 7. By connecting the temperature sensor to the demodulation analyzer, the temperature signal can be transmitted to the demodulation analyzer. After being processed by the data conditioning and analysis module of the demodulation analyzer, the temperature data is then sent to the communication module. Attached Figure Description

[0043] Example 1

[0044] A railway vehicle brake shoe temperature detection device, the specific structure of which is as follows: Figures 1-3 As shown, it includes a constant contact mechanism 1, which is fixedly connected to the brake shoe holder 12. A temperature sensor 2 is connected to the constant contact mechanism 1 and is movably mounted on the constant contact mechanism 1.

[0045] By fixing the constant contact mechanism 1 to the brake shoe support 12, support can be provided for the temperature sensor 2, ensuring that the temperature sensor 2 can measure the temperature of the brake shoe 11. The temperature sensor 2 follows the movement of the brake shoe support 12 and is not affected by the positional changes of the brake shoe 11 due to wheel wear. By movably positioning the temperature sensor 2 on the constant contact mechanism 1, when the brake shoe 11 needs to be replaced, only the temperature sensor 2 needs to be moved to complete the replacement of the brake shoe 11. This solves the technical problem in the prior art where frequent replacement of the brake shoe 11 cannot stably measure the temperature, and greatly reduces the probability of damage to the temperature sensor 2 during the disassembly and assembly of the brake shoe 11.

[0046] Example 2

[0047] As a preferred embodiment of the present invention, the following improvements were made based on Embodiment 1, and the specific structure is as follows: Figures 1 to 3 As shown, the constant contact mechanism 1 includes a bracket 3 and a connecting seat 4.

There are two torsion springs 8. A sleeve 9 is provided on the pin 7 between the torsion spring 8 and the connecting seat 4. There are two sleeves 9.

[0048] By setting the connecting seat 4, the connecting seat 4 and the brake shoe support 12 are kept fixed, and the bracket 3 can rotate around the connecting seat 4.

[0049] By setting a guide slope 5, the guide slope 5 extends into the brake shoe support 12. When the brake shoe pin 13 contacts the guide slope 5, the temperature sensor 2 contacts the brake shoe 11 under the drive of the bracket 3, which makes installation convenient.

[0050] By setting the torsion spring 8, when the brake shoe pin 13 separates from the guide slope 5, the bracket 3 rotates under the drive of the torsion spring 8, and drives the temperature sensor 2 away from the brake shoe 11.

[0051] By setting the sleeve 9, the bracket 3 can be prevented from moving up and down on the connecting seat 4, which would affect the temperature detection.

The connection between the temperature sensor 2 and the demodulation analyzer 10 is a wired connection. The demodulation analyzer 10 includes a power module, a data demodulation analysis module, and a communication module.

[0054] By connecting the temperature sensor 2 to the demodulator 10, the temperature signal can be transmitted to the demodulator 10. After being processed by the data conditioning and analysis module of the demodulator 10, the temperature data is then sent to the communication module.
