Abstract
Description
Technical Field
[0001] This utility model relates to a wear alarm device for drive drum brake plates, belonging to the technical field of alarm devices. Background Technology
[0002] The operation of a conveyor primarily relies on the rotation of the drive drum to drive the conveyor belt. In emergency situations, the drive drum brake device generates friction between the brake pads and the brake disc, thereby hindering the drum's rotation and achieving the purpose of slowing down or stopping the drum's movement. As an emergency braking device for the drum, the reliability of the brake pads is of significant practical importance for improving safe production. Traditionally, drum brake pad wear is checked by personnel on-site to see if it has reached the required replacement size. However, this method can lead to accidents if excessive wear occurs due to missed inspections. Modern drum brake pad wear detection methods rely on instruments and alarm devices such as infrared detection and probe detection, but these instruments are too expensive. Therefore, it is necessary to apply a cost-effective drive drum brake pad wear alarm device to solve this problem. Summary of the Invention
[0003] The purpose of this invention is to provide a wear alarm device for a drive drum brake pad. It uses an iron sheet comprising a fixed end and an S-shaped middle section as the alarm device. When the brake pad wears out due to prolonged use, the alarm device contacts the brake disc and emits a harsh metallic friction sound, thus reminding the user to replace the brake pad to prevent accidents. This invention is inexpensive, simple, and effective. The S-shaped structure increases the device's flexibility, extending its service life and effectively solving the aforementioned problems in the prior art.
[0004] The technical solution of this utility model is: a drive drum brake pad wear alarm device, comprising a drive motor, a brake disc, a brake caliper, a brake pad, and an alarm device. The drive drum is driven to rotate by the drive motor. The brake disc and the brake pad are matched and arranged. The brake caliper is set at the top of the brake pad. The alarm device is an S-shaped iron plate. One end of the alarm device is provided with a fixing hole, which is fixed to the inner wall of the brake caliper by bolts. The other end of the alarm device is higher than the brake pad, and the length of its protruding part matches the wear limit value of the brake pad.
[0005] The S-shaped iron plate of the alarm device has multiple S-shaped bends.
[0006] The alarm device is 45mm long, 8mm wide, and 2mm thick.
[0007] The length of the alarm device extending above the brake pad is 3-5mm higher than the wear limit of the brake pad.
[0008] The beneficial effects of this utility model are: by using an S-shaped iron sheet as an alarm device, when the brake pad wears out due to long-term operation, the alarm device contacts the brake disc and emits a harsh metallic friction sound to serve as an alarm, thereby reminding the brake pad to be replaced to prevent accidents. It is inexpensive, simple and effective. The S-shaped structure can increase the flexibility of the device and extend its service life. Attached Figure Description

[0013] To make the purpose, technical solution, and advantages of the utility model embodiments clearer, the technical solution of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only a small part of the utility model embodiments, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the utility model without creative effort are within the protection scope of the utility model.
[0014] A drive roller brake pad wear alarm device includes a drive motor 1, a brake disc 2, a brake caliper 3, a brake pad 4, and an alarm device 5. The drive roller 7 is driven to rotate by the drive motor 1. The brake disc 2 and the brake pad 4 are matched and arranged. The brake caliper 3 is located at the top of the brake pad 4. The alarm device 5 is an S-shaped iron plate. One end of the alarm device 5 is provided with a fixing hole 6, which is fixed to the inner wall of the brake caliper 3 by bolts. The other end of the alarm device 5 is higher than the brake pad 4, and the length of its protruding part matches the wear limit value of the brake pad 4.
[0015] The S-shaped iron plate of the alarm device has multiple S-shaped bends.
[0016] The alarm device 5 is 45mm long, 8mm wide, and 2mm thick.
[0017] The length of the part of the alarm device 5 that extends above the brake pad 4 is 3-5mm higher than the wear limit of the brake pad 4.
[0018] In practical applications, the drive roller 7 is rotated by the drive motor 1. In emergency situations, the brake caliper 3 causes friction between the brake pad 4 and the brake disc 2, thus hindering the roller's rotation and achieving the purpose of slowing down or stopping the roller's movement. The alarm device 5 is an S-shaped iron sheet, 45mm long, 8mm wide, and 2mm thick. Its fixed end is bolted to the inner wall of the brake caliper 3 through the fixing hole 6, and the other end is 3-5mm longer than the wear limit of the brake pad 4. The S-shaped structure increases the flexibility of the alarm device 5, extending its service life. When the brake pad 4 wears down due to prolonged use, the alarm device 5 contacts the brake disc 2 and emits a harsh metallic friction sound, serving as an alarm. This reminds the user to replace the brake pad 4 to prevent accidents.
