[0030] Working principle:

[0031] The metal back plate 1 is the foundation of the whole device, which provides strength and stability. Fixing ears 9 extend from both ends of the metal back plate to fix the ear-shaped spring sheet 4. The friction block 2 is the part that actually performs friction and contacts the surface that needs to be braked. The friction block is provided with a chamfered surface 7, which helps to adapt to and fit the braking surfaces of different shapes and angles more quickly, provides a uniform friction effect, and can also assist in heat dissipation and the discharge of waste chips through the first groove 8 and the second groove 10; the silencer 3 is installed at the bottom end of the metal back plate to reduce the noise generated during the friction process, and may also play a role in heat dissipation; the ear-shaped spring sheet 4 is installed on the metal back plate through the fixing ear 9, and can effectively reduce the vibration generated during braking through elasticity, thereby improving the stability of braking; the temperature sensor 5 is installed on the metal back plate through the first opening 13 to monitor the temperature of the friction block and the metal back plate in real time; the wear alarm sensor 6 is installed on the metal back plate through the second opening 14 to detect the degree of wear of the friction block. Through the ear-shaped spring sheet 4 and the fixing ear 9, the entire device is firmly installed in the required position. The elasticity of the ear-shaped spring sheet 4 ensures that the device can adapt to various installation environments and provides a certain preload force to make the friction block and Maintaining close contact with the braking surface provides adaptability and stability, and can effectively reduce vibration during braking; when braking is required, the friction block 2 contacts the surface of the brake disc and generates friction. Due to the design of the two sets of chamfered slopes 7, the friction block 2 can adapt to and fit the surfaces of brake discs of different shapes and angles more quickly, thereby providing a more uniform and effective friction effect; the temperature sensor 5 is installed on the metal back plate 1 through the first opening 13 to monitor the temperature of the friction block 2 in real time. When the temperature is too high, it may indicate that the friction block 2 is excessively worn or there are other problems. At this time, the system can issue a warning or take corresponding measures; the wear alarm sensor 6 is installed on the metal back plate 1 through the second opening 14 to detect the degree of wear of the friction block 2. When the wear reaches a certain degree, the wear alarm sensor 6 will send a signal to remind the operator to replace the friction block 2; wear warning lines 15 are provided on the side walls of the friction block 2. As the friction block 2 wears, these warning lines will gradually appear. The operator can judge the remaining life of the friction block 2 by observing the state of the warning line; in addition to reducing noise, the silencer 3 may also have the function of heat dissipation, helping to reduce the temperature of the friction block 2, thereby extending its service life; when the friction block 2 is worn to a certain extent, the operator can replace the new friction block 2 by removing the fixing ear 9 and the ear-shaped spring sheet 4. At the same time, the temperature sensor 5 and the wear alarm sensor 6 can also be easily checked and replaced; an effective braking function is achieved, and real-time temperature, wear monitoring and alarm functions are provided through various sensors and warning devices, ensuring the safe and reliable operation of the device.
