Description

Technical Field

[0001] The utility model belongs to the technical field of brake heating equipment, and particularly relates to a heating and heat preservation device for a rail vehicle plate brake. Background Technique

[0002] In cold regions, such as high-latitude regions or regions with severe winters, the rail vehicle plate brake faces performance challenges in low-temperature environments. Low temperature can cause the gas inside the brake to liquefy, corrode the internal components of the brake, and even cause icing, blocking the air holes, thus affecting the braking effect.

[0003] Therefore, the design of the heating and heat preservation device needs to solve the problem of maintaining the normal operation of the brake in a low-temperature environment, ensuring that the brake can work normally in a low-temperature environment, avoiding performance degradation or failures caused by too low temperature, and ensuring the reliability and safety of the rail vehicle braking system. Summary of the Invention

[0004] In order to overcome the performance challenges faced by the rail vehicle plate brake in a low-temperature environment in cold regions, where low temperature can cause the gas inside the brake to liquefy, corrode the internal components of the brake, and even cause icing, blocking the air holes, thus affecting the braking effect, the utility model provides a heating and heat preservation device for a rail vehicle plate brake; when the temperature sensor senses that the temperature of the brake is lower than the preset value, it transmits a signal to the controller, and the controller controls the resistance wire to heat the brake, preventing water vapor from condensing on the surface of the brake, reducing the occurrence of corrosion, protecting the equipment from damage, and at the same time effectively preventing the gas inside the brake from freezing at low temperatures, avoiding performance degradation or failures of the gas caused by freezing.

[0005] To achieve the above object, the utility model is realized through the following technical solutions: A heating and heat preservation device for a rail vehicle plate brake mainly includes a mounting plate, a clamping plate, fastening bolts, a resistance wire, insulating tape, wires, a temperature sensor, and a controller. Installation grooves are opened at both ends of the mounting plate, convex blocks are provided at both ends of the clamping plate, and the clamping plate is installed in the installation groove through the convex blocks and the fastening bolts. Strip-shaped grooves and rectangular grooves are opened inside the mounting plate and the clamping plate. The resistance wire is installed inside the strip-shaped groove through the insulating tape, and the insulating tape is pasted on the top of the resistance wire. The wires are installed in the rectangular groove, and the resistance wire is connected to the wires. Threaded holes for facilitating the installation of the brake are provided on both the mounting plate and the clamping plate. The temperature sensor is installed in the rectangular groove, the controller is installed on the mounting plate, the resistance wire, the temperature sensor and the controller are electrically connected. The temperature sensor is installed in the rectangular groove, the controller is installed on the mounting plate, the resistance wire, the temperature sensor and the controller are electrically connected.

[0006] The installation plate and the clamping plate described above can be set to one or more according to the size of the brake.

[0007] The insulating tape described above is a transparent insulating tape.

[0008] Advantages of the present utility model:

[0009] When the temperature sensor senses that the temperature of the brake is lower than the preset value, it transmits a signal to the controller, and the controller controls the heating wire to heat the brake. The setting of the heating wire prevents water vapor from condensing on the surface of the brake, reduces the occurrence of corrosion, protects the equipment from damage, and effectively prevents the gas inside the brake from freezing at low temperatures, maintaining its good fluidity, avoiding the decline in braking performance or failures caused by gas freezing, ensuring that the brake can still work reliably in a low-temperature environment, and thus improving the running safety of the rail vehicle.

[0014] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the preferred embodiments of the present utility model will be described in detail below with reference to the drawings for the convenience of those skilled in the art to understand.

[0015] 1. The utility model discloses a heating and heat preservation device for a rail vehicle plate type brake. The heating and heat preservation device for a rail vehicle plate type brake mainly comprises a mounting plate 1, a clamping plate 2, fastening bolts 3, a resistance wire 4, insulating tape 5, an electric wire 6, a temperature sensor 7, and a controller 8. Installation grooves 11 are formed at both ends of the mounting plate 1. Protrusions 21 are arranged at both ends of the clamping plate 2. The clamping plate 2 is installed in the installation grooves 11 through the protrusions 21 and the fastening bolts 3. Strip-shaped grooves 12 and rectangular grooves 13 are formed inside both the mounting plate 1 and the clamping plate 2. The resistance wire 4 is installed inside the strip-shaped groove 12 through the insulating tape 5. The insulating tape 5 is pasted on the top of the resistance wire 4. The electric wire 6 is installed in the rectangular groove 13. The resistance wire 4 is connected to the electric wire 6. Threaded holes 22 facilitating the installation with the brake are arranged on both the mounting plate 1 and the clamping plate 2. The temperature sensor 7 is installed in the rectangular groove 13. The controller 8 is installed on the mounting plate 1. The resistance wire 4, the temperature sensor 7 and the controller 8 are electrically connected. The mounting plate 1 and the clamping plate 2 are installed on the brake through the cooperation of bolts and the threaded holes 22.

[0016] During the operation of the brake, the temperature sensor 7 senses the temperature of the brake. When the temperature sensor 7 senses that the temperature of the brake is lower than the preset value, it transmits a signal to the controller 8. The controller 8 controls the resistance wire 4 to heat the brake. The setting of the resistance wire 4 prevents water vapor from condensing on the surface of the brake, reduces the occurrence of corrosion, protects the equipment from damage, and effectively prevents the gas inside the brake from freezing at low temperatures, maintaining its good fluidity, avoiding the decline of braking performance or failure caused by gas freezing, ensuring that the brake can still work reliably in a low-temperature environment, thereby improving the operation safety of the rail vehicle. When the temperature sensor 7 senses that the temperature of the brake reaches the preset value, it transmits a signal to the controller 8. The controller 8 controls the resistance wire 4 to stop heating.

[0017] The mounting plate 1 and the clamping plate 2 can be set to one or more according to the size of the brake; the installation and disassembly are convenient and fast.

[0018] The insulating tape 5 is a transparent insulating tape; when a single resistance wire 4 is damaged and needs to be repaired or replaced, only need to tear off the pasted insulating tape 5 and repair or replace the resistance wire 4.

[0019] Working process:

[0020] First, the staff selects the number of mounting plates 1 and clamping plates 2 to be installed according to the size of the brake. Subsequently, the clamping plate 2 is installed on the mounting plate 1 through the fastening bolt 3. Then, the resistance wire 4 is installed inside the mounting groove 11 through the insulating tape 5. One end of the wire 6 is connected to the resistance wire 4, and the other end is connected to the power supply. After the connection is completed, the mounting plate 1 and the clamping plate 2 are installed on the brake through the bolts and the threaded holes 22. During the operation of the brake, the temperature sensor 7 senses the temperature of the brake. When the temperature sensor 7 senses that the temperature of the brake is lower than the preset value, it transmits a signal to the controller 8. The controller 8 controls the resistance wire 4 to heat the brake. The setting of the resistance wire 4 prevents water vapor from condensing on the surface of the brake, reduces the occurrence of corrosion, protects the equipment from damage, and effectively prevents the gas inside the brake from freezing at low temperatures, maintaining its good fluidity, avoiding the decline of braking performance or failures caused by gas freezing, ensuring that the brake can still work reliably in a low-temperature environment, thereby improving the running safety of the railcar. When the temperature sensor 7 senses that the temperature of the brake reaches the preset value, it transmits a signal to the controller 8, and the controller 8 controls the resistance wire 4 to stop heating.
