The method of partial replacement of the conveyor belt

Abstract

The invention discloses a method for partially replacing a conveyor belt. The method includes: S1, punching holes. S2, making the anchor rod, the front end of the anchor rod is provided with a lifting ring. S3, anchoring the anchor rod into the hole. S4, rotate the conveyor belt to be replaced to the leveling section on the well, and loosen the tensioning device. S5, the belt card is fixed on the conveyor belt, the two ends of the belt card are connected with the anchor rods on the roadway wall through the wire rope, and the conveyor belt is tightened. S6, release the conveyor belt stored in the belt storage device, loosen the conveyor belt, cut off the two ends of the conveyor belt to be replaced, connect the new conveyor belt to the old conveyor belt in place of the conveyor belt to be replaced, and use the old conveyor belt Towing lays the new conveyor belt in place. S7, using the belt storage device to tension the conveyor belt, release the connection between the belt card and the suspension ring, and remove the belt card. S8, releasing the conveyor belt stored in the belt storage device, and tensioning the tensioning device at the tail of the belt conveyor. The method for partially replacing the conveyor belt of the present invention can improve the replacement efficiency.

Description

technical field [0001] The invention relates to the technical field of belt conveyors in inclined shafts, in particular to a method for partially replacing conveyor belts. Background technique [0002] As an inclined shaft belt conveyor for lifting, it has the advantages of simple structure, large transportation capacity, long transportation distance, and continuous operation. It is widely used in various large-scale mines such as coal mines and iron mines. The structure of this type of belt conveyor can be found in the attached figure 1 , a is the leveling section above the well, b is the lifting section of the inclined shaft, c is the leveling section under the well, section a is usually outside the shaft of the inclined shaft, and b and c are usually inside the shaft. [0003] Since the conveyor belt of the inclined shaft belt conveyor is generally long, the damage degree of each part of the conveyor belt is different, and it is often necessary to partially replace the s...

AI Technical Summary

Problems solved by technology

The conventional method of partial replacement of the conveyor belt is to replace it in section c (the downhole leveling section), which has the advantage of not having to consider the risk of sliding after the conveyor belt is broken. The disadvantages are ① the underground working space is small and the construction safety factor is low ② replacement The length of the conveyor belt is greatly affected by the underground transportation tools. When the conveyor belt is replaced for a long time, it will cause segmental transportation and segmental vulcanization, which not only increases the cost of joint rubber materials and construction costs, but also doubles the replacement time. At the same time, the conveyor belt joint An increase in the number will increase the risk of belt breakage
