Description

Technical Field

[0001] The utility model relates to the field of universal conveyor belt accessories, in particular to a tubular conveyor belt roller mechanism. Background Art

[0002] Tubular conveyor belts are used in more and more fields due to their many advantages such as environmental protection, small turning radius and long transportation distance. They are especially used to transport materials with serious dust, such as coal, sand and gravel. During the transportation process, the belt is rolled into a tubular shape to prevent materials from falling and dust from being generated during the conveyor belt transportation process.

[0003] However, there are many drawbacks of this type of conveying equipment that cannot be overcome at present, including: First, the belt is tubular, and it is impossible to install an automatic deviation correction device. The belt can only be adjusted by adjusting the gasket to adjust the belt rotation (deviation). When it rains, the material is unevenly loaded, or the belt is aged and the elasticity is reduced, it is very easy to cause the belt to rotate; serious rotation will cause coal to spill at the belt joint. Second, because most tubular conveyor belts are installed at high altitudes and have long transportation distances, it is difficult to transport and replace damaged rollers, resulting in high operating and maintenance costs and cumbersome maintenance procedures. Utility Model Content

[0004] The utility model aims to overcome the shortcomings of the prior art and provide a tubular conveyor belt roller mechanism which has a simple structure, a long maintenance period and can effectively prevent the belt from rotating and running off the track during operation.

[0005] The equipment includes a main frame, which is the supporting mechanism of the equipment and also the assembly basis of the equipment;

[0006] A belt roller is arranged inside the main frame, and a plurality of belt rollers are arranged in a circular array;

[0007] The belt roller comprises a roller shaft, a bearing, a roller shaft oil seal and an outer sleeve;

[0008] The roller shaft is arranged on the main frame, bearings are arranged at both ends of the roller shaft, and bearing oil seals are arranged on the outer sides of the two bearings;

[0009] The edges of the fitting surfaces of the bearing and the bearing oil seal are respectively smoothly chamfered, and the gap between them is the oil channel;

[0010] The roller shaft is provided with oil filling holes at both ends, and an oil overflow hole is provided on the roller shaft between the bearing and the bearing oil seal;

[0011] A silicone plug is provided at the oil filling hole;

[0012] The effect achieved in this way is that oil is injected through the oil filling hole, and the lubricating oil overflows through the oil overflow hole to the oil channel position in the gap between the joint surface of the bearing and the bearing oil seal. The oil channel here refers to the smooth chamfer setting of the outer ring of the joint surface of the bearing and the bearing oil seal, and oil overflows from the oil channel position of the two chamfered grooves; the overflowing lubricating oil soaks the balls between the inner and outer sleeves of the bearing, plays a role in maintenance and lubrication, and can greatly increase its service life.

[0013] An outer sleeve is fixedly arranged outside the bearing, and an array of anti-skid bosses is arranged on the outer sleeve.

[0014] The effect achieved in this way is that the tubular belt is transported at high speed through multiple belt rollers. On the one hand, the anti-skid boss can enhance the friction between the tubular belt and the rollers, thereby preventing the tube from rotating; on the other hand, the anti-skid boss part can play a wear-resistant role. For example, it is common for belt rollers to wear out in the middle after long-term operation, and the anti-skid boss can greatly delay this process and extend the service life of the rollers.

[0015] The beneficial effects of the utility model are as follows: the utility model solves the technical defects of the tubular conveyor belt in the prior art, and through its oil seal and oil filling hole design, it can effectively and regularly lubricate its rotating friction part to ensure the service life of the equipment. The anti-slip boss arranged on its outer sleeve can, on the one hand, enhance the friction between the belt and the roller to prevent the tube from rotating, and on the other hand, it can increase the service life of the equipment and extend the maintenance cycle.
