Description

Technical Field

[0001] The utility model provides a special measuring tool for belt thickness, belonging to the technical field of mechanical measurement. Background Technique

[0002] Belt drive has the advantages of simple structure, easy maintenance and adjustment, etc., so it is widely used in various mechanical equipment and means of transportation, such as machine tools, steel plants, mines, automobiles, motorcycles, bicycles, household appliances, and agricultural machinery, etc. This technology has various advantages, such as long-distance conveying capacity, large conveying volume, continuous conveying, operation reliability, and easy realization of automatic control, etc. In recent years, with the continuous progress of technology, the role of belt conveying in fields such as mines and tunnel construction has become increasingly important.

[0003] In the mining field, belt conveyors have become key equipment for efficient ore transportation. It can not only conduct long-distance and large-volume ore transportation, but also realize automatic and centralized control. The advantages of continuous belt conveyors in mines include improving tunneling speed, reducing the burden on construction workers, low pollution emissions, and adapting to transportation under different inclination conditions, etc.

[0004] At present, industrial belts are rich in variety. According to the material, they can be divided into rubber industrial belts, polyurethane industrial belts, polyester industrial belts, etc.; according to the function, they can be divided into conveyor belts, transmission belts, synchronous belts, etc. These different types of industrial belts play their respective roles in different transmission fields.

[0005] During the use of the belt, there will be wear and tear, and wear may bring a series of serious consequences, which are specifically manifested as follows:

[0006] The transmission efficiency decreases: Due to the long-term frictional effect, the surface of the belt will gradually wear and become smooth, resulting in the belt losing its original elasticity and energy storage capacity, and thus reducing the transmission efficiency.

[0007] The load capacity decreases: Under high-load conditions, the worn belt often bears huge tensile forces and torques, and is prone to stretching deformation and cracking, affecting the transmission efficiency and service life.

[0008] Noise and vibration: The worn belt may generate abnormal noise and vibration during transmission, which not only affects the normal operation of the equipment, but may also cause interference to the surrounding environment and personnel.

[0009] Equipment damage: When the belt is severely worn, it may cause damage to other components of the equipment, such as bearings, gears, etc., thus increasing the maintenance cost and downtime of the equipment.

[0010] Safety hazard: In some special cases, such as in high-speed rotating equipment, a worn belt may suddenly break, causing safety accidents such as equipment shutdown and material scattering, posing a serious threat to personnel and equipment.

[0011] With the standardization and improvement of industrial safety, the safe operation of belts is particularly important. Whether it is belt replacement or maintenance, corresponding operating time, maintenance records, and replacement cycles need to be recorded. By analyzing data, the wear condition of the belt can be predicted. Currently, the main methods for detecting belts are steel rulers or calipers, which have limitations in detecting different points. Therefore, it is particularly important to design a thickness measurement tool for different points of the belt. During each belt repair and replacement, the worn positions are detected to monitor the belt thickness, understand the wear condition of the belt, avoid the serious consequences caused by belt wear, and ensure the normal operation of the belt and safe production.

A movable hole is provided at the upper end of the opening of the measuring ruler frame and a rigid movable thimble is passed through. The position of the movable hole corresponds to the thimble base; a scale is provided beside the rigid movable thimble at the top end of the measuring ruler frame.

[0023] Place the belt to be measured inside the measuring ruler frame. The lower part of the movable thimble contacts the measuring point. At this time, the other side of the belt contacts the thimble base. The scale pointer on the upper part of the movable thimble will point to the corresponding scale on the scale.
