Description

Technical Field

[0001] The utility model relates to a conveyor belt anti-deviation structure and belongs to the technical field of coal mine machinery. Background Art

[0002] Coal is a solid combustible mineral that was gradually formed when ancient plants were buried underground and underwent complex biochemical and physicochemical changes. Coal is the most abundant and widely distributed fossil fuel on earth. The elements that make up coal's organic matter mainly include carbon, hydrogen, oxygen, nitrogen and sulfur, in addition to very small amounts of phosphorus, fluorine, chlorine and arsenic. Coal is hailed as black gold and industrial food. It has been one of the main energy sources used by the human world since the 18th century. Since the 20th century, although the value of coal is much lower than before, it has been one of the indispensable sources of energy for our production and life for a long time. The supply of coal is also related to the stability of the development of our country's industry and even the entire society. The issue of coal supply security is also the most important link in our country's energy security.

[0003] The coal lifting device is a conveying device specially used for transporting coal. It uses a motor to drive the conveyor belt to transport the coal to the designated location. Traditional coal conveying devices only have pulleys at the starting and end of the conveyor belt. After running for a period of time, the conveyor belt will deviate, resulting in some coal failing to accurately reach the designated location, causing economic losses. Utility Model Content

[0004] The utility model aims to solve the problem that a traditional coal lifting conveyor belt may deviate after running for a period of time, resulting in some coal failing to accurately reach a designated location and causing economic losses, and thus proposes a structure for preventing the coal lifting conveyor belt from deviating.

[0005] The technical solution adopted by the utility model to solve the above problems is: the utility model includes a pulley shaft, two pulleys and a belt, the two pulleys are coaxially fixedly sleeved on the two ends of the pulley shaft, and the belt is sleeved on the pulley; the pulley is provided with a first positioning section, a second positioning section, a third positioning section and a fourth positioning section in sequence from the inside to the outside, and the edge of the inner surface of the belt is provided with an insertion strip and a slot from the outside to the inside, and the center line of the insertion strip along the length direction and the center line of the slot along the length direction are both parallel to the center line of the belt along the length direction, the insertion strip is inserted between the third positioning section and the fourth positioning section, and the second positioning section is inserted into the slot.

[0006] Furthermore, the diameter of the first positioning segment is D1, the diameter of the second positioning segment is D2, the diameter of the third positioning segment is D3, the diameter of the fourth positioning segment is D4, and D1 <D3<D2,D3<D2<D4。

[0007] Furthermore, a first inclined surface is provided on a side of the second positioning section close to the first positioning section, and a second inclined surface is provided on a side of the second positioning section close to the third positioning section.

[0008] Furthermore, the included angle between the first inclined surface and the surface of the first positioning section is 111°, and the included angle between the second inclined surface and the surface of the third positioning section is 115°.

[0009] Furthermore, a third inclined surface is provided on a side of the fourth positioning section close to the third positioning section.

[0010] Furthermore, the included angle between the third inclined surface and the surface of the third positioning section is 100°.

[0011] Furthermore, the edge of the lower surface of the belt is provided with a convex edge extending outward, and the lower surface of the convex edge is in contact with the surface of the fourth positioning section.

[0012] The beneficial effects of the utility model are:

[0013] 1. The utility model can strictly limit the belt between two pulleys, realize the precise operation of the belt, avoid deviation, and eliminate the economic losses caused by deviation of the belt;

[0014] 2. The traditional belt anti-deviation structure only extends the edge of the pulley to make its height greater than the belt surface. However, the belt will be fatigued and deformed after a period of use. When the fatigue deformation of the belt reaches a certain degree, the belt edge will curl and deviate. In severe cases, the belt will be separated from the pulley. The utility model provides a strip and a double-row strip structure on the lower surface of the belt edge to achieve positioning. Even if the belt is fatigued and curled, the lower surface of the edge will not deviate or separate from the pulley.

[0015] 3. The utility model has a simple structure. The second inclined surface, the third inclined surface and the third positioning section form a positioning groove, and the insert can be easily and quickly inserted into the positioning groove. BRIEF DESCRIPTION OF THE DRAWINGS
