[0002] During the transportation of calcium carbide, due to the long-term use of the belt conveyor, the conveyor belt is prone to wear and tear, so it is necessary to replace the belt. When replacing the conveyor belt, the old belt needs to be removed after the new belt is installed. Usually, the old belt is cut manually with a utility knife and then taken out in sections, or if the site is large enough, the old belt is forcibly pulled out with equipment and then cut into sections. Regardless of the above methods, a large amount of manpower is required. The number of people working together increases the risk of belt maintenance operations. After the operation, in order to solve the problem of the old belt occupying a large area, it is necessary to manually cut and roll it into small rolls for storage. The process of cutting and rolling the conveyor belt is very likely to cause mechanical injury accidents to maintenance personnel. In addition, belt replacement operations are often an operation with extremely strict time requirements. Continuous production systems do not have much time left for maintenance operations, and usually they must be restored to standby within a day to ensure the stable operation of the production system.

[0018] See also Figure 1-2 The utility model provides a technical solution for the conveyor belt replacement and recycling winding device:

[0019] A conveyor belt replacement and recycling winding device includes a first bracket 1, a driving roller 2, an MB stepless speed regulating motor 3, a second bracket 4, a fixing plate 5, a first straightening roller 6, a belt pressing roller 7, a belt supporting roller 8, a steel pipe 9, a sleeve 10, a third bracket 11, a round rod 12, and a second straightening roller 13;

[0020] An active roller 2 is rotatably provided on the first bracket 1, and one end of the active roller 2 is connected to the output shaft of the MB stepless speed regulation motor 3. A fixed plate 5 is connected between the second bracket 4 and the first bracket 1. The upper surface of the fixed plate 5 is provided with two first correction rollers 6, a belt holding roller 7 and a belt supporting roller 8 that rotate in sequence along the direction close to the second bracket 4. The two first correction rollers 6 are on the same side and are perpendicular to the belt holding roller 7. The belt holding roller 7 and the belt supporting roller 8 are both horizontally arranged. Arc grooves 4.1 are provided at the two upper ends of the second bracket 4. A steel pipe 9 is overlapped between the two arc grooves 4.1. A sleeve 10 is rotatably provided on the steel pipe 9. Two round sticks 12 distributed upper and lower are horizontally rotatably provided between the top of the third bracket 11, and second correction rollers 13 are vertically rotatably provided on both sides of the top of the third bracket 11.

[0021] Bearings 14 are fixed at both ends of the top of the first bracket 1, and an active roller 2 is fixed between the inner rings of the two bearings 14. A support plate 1.1 is fixed to one side of the first bracket 1, and the MB stepless speed regulation motor 3 is fixed on the support plate 1.1. The active roller 2 is connected to one end of the old belt 15 through a steel wire rope, so that the old belt 15 is wound around the surface of the active roller 2.

[0022] The fixing plate 5 is fixed to the upper surfaces of the first bracket 1 and the second bracket 4 by bolts.

[0023] The distance between the two first correction rollers 6 is the same as the width of the old belt 15, and the distance between the two second correction rollers 13 is the same as the width of the old belt 15. The old belt 15 is placed between the two first correction rollers 6 and the two second correction rollers 13, which can ensure that the old belt 15 moves along a straight line, so that the old belt 15 will not deviate during the winding process.

[0024] The upper surface of the old belt 15 is movably fitted with the lower surface of the belt holding roller 7, and the lower surface of the old belt 15 is movably fitted with the upper surface of the belt support roller 8, so that the old belt 15 can be stably wound.

[0025] The new belt 16 has the same size as the old belt 15 . The new belt 16 is wound around the sleeve 10 and placed between two round sticks 12 distributed up and down. One end of the new belt 16 is connected to the other end of the old belt 15 .

[0026] The principle of the belt replacement process of this utility model is as follows:

[0027] Place the prepared new belt 16 in the two arc-shaped grooves 4.1 on the second bracket 4 through the steel pipe 9, then cut off the old belt 15 at the tail of the belt conveyor, and vulcanize and fix the upper end of the old belt 15 to one end of the new belt 16 on the sleeve 10, and fix the lower end of the old belt 15 to the surface of the active roller 2 through a steel wire rope.

[0028] Subsequently, the MB stepless speed regulating motor 3 is started, and the active roller 2 is controlled to rotate clockwise to start winding up the old belt 15. At the same time, as the old belt 15 is wound up, the new belt 16 will also be pulled by the old belt 15 to make the sleeve 10 rotate clockwise and gradually release the new belt 16, so that the new belt 16 is pulled onto the belt conveyor by the old belt 15 for replacement. In order to ensure that the new belt 16 moves evenly during the replacement process, it is necessary to manually observe and adjust the speed of the MB stepless speed regulating motor 3 until the new belt 16 completely replaces the old belt 15, and then turn off the MB stepless speed regulating motor 3, cut the connection between the old belt 15 and the new belt 16, and vulcanize and fix the two ends of the new belt 16 together. By tensioning the new belt 16, the replacement of the new belt 16 and the winding of the old belt 15 are finally completed.

[0029] This solution reduces the frequency of mechanical contact among maintenance personnel, effectively controlling the risk of mechanical injury; it reduces the number of personnel involved in maintenance, lowering the risk level of maintenance operations; and it shifts the physical expenditure of maintenance personnel to equipment operation, monitoring, and inspection, reducing the labor intensity of maintenance personnel; mechanized synchronous recovery shortens maintenance time and improves maintenance efficiency.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
