Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyors, in particular to a belt rolling device. Background Art

[0002] Belt conveyors are devices used to transport materials over long distances. They are widely used in the fields of construction, food, mining, metallurgy, etc. Belts may be damaged by wear or other reasons during the material conveying process. If left unchecked, more serious consequences such as belt breakage may occur. Therefore, they need to be replaced or repaired in a timely manner.

[0003] Since the belt is a rubber product and is relatively heavy, when replacing it, it is usually pulled out from the belt rack by a forklift, winch or other equipment, but it still needs to be rolled up manually. This rolling method is time-consuming and labor-intensive, extremely inconvenient to operate, and it is very easy to cause personal injury during the rolling process. Manually rolled belts are shorter and more cumbersome to transport and lift. The replaced belt is shorter due to manual rolling, and the belt roll is not tightly wound, which is not conducive to secondary use and causes a waste of resources. Therefore, it is very necessary to improve the rolling method of the old belt.

[0004] The document with application number CN202222803929.0 and title “A Mechanical Belt Winding Device” in the Chinese Patent Database provides a winding device, including a mounting frame and a rolling part; the mounting frame is provided with two support beams in parallel; the two wheel frames of the rolling part are respectively provided at one end of the two support beams; a pair of rollers are provided in parallel on the two wheel frames, and the axial directions of the rollers are perpendicular to the axial directions of the support beams; the end of the support beam away from the wheel frame cooperates with a trolley. The device drives the rollers to rotate through the trolley, so that the belt is rolled up, but the operation of the trolley requires a certain distance, is only suitable for use in open areas, and requires professional manual operation. Therefore, a belt winding device with easy operation and simple structure is needed to improve the winding efficiency and winding quality. Utility Model Content

[0018] See also Figure 1 The utility model includes a base 1, a lifting mechanism and a winding mechanism. The base 1 is provided with a lifting mechanism, and the lifting mechanism is mounted on the winding mechanism; the winding mechanism includes a hydraulic motor 2 and a belt reel 6, the hydraulic motor 2 is arranged on both sides of the belt reel 6, and the hydraulic motor 2 drives the belt reel 6 to rotate to complete the work of winding the belt; the belt reel 6 includes a central axis 16, a support plate 11, a connecting rod 12 and a connecting plate 13, the two ends of the central axis 16 are threaded rods 15, and the threaded rods 15 at both ends are threadedly connected with adjusting nuts 14; the support plate 11 is an arc plate, along the central axis The outer wall of the central shaft 16 is arranged in a surrounding manner, and the inner wall of the support plate 11 can be fitted with the outer wall of the central shaft 16, and the inner walls at both ends of the support plate 11 are respectively movably connected with connecting rods 12, and the connecting rods 12 movably connect the support plate 11 to the connecting disk 13, and the connecting disk 13 is connected to the central shaft 16 through a sliding key 20, so that the connecting disk 13 can move left and right along the central shaft 16, but will not rotate with the rotation of the central shaft 16; by adjusting the angle between the connecting rod 12 and the connecting disk 13, the distance between the support plate 11 and the central shaft 16 can be changed, so that the center diameter of the rolled belt can be adjusted.

[0019] The adjusting nuts 14 on the threaded rod 15 are all arranged on the outside of the connecting plate 13. By rotating the adjusting nuts 14 at both ends of the threaded rod 15, the connecting plates 13 on both sides can be pushed to move inward or outward along the axial direction, thereby adjusting the angle between the connecting rod 12 and the connecting plate 13. The outer wall of the sliding key 20 is threaded, so that the adjusting nut 14 can be used normally on the threaded rod 15. Two to six support plates 11 can be arranged around the central axis 16.

[0020] See also Figure 2The lifting mechanism includes a platform 17, a lifting hydraulic cylinder 3, a hydraulic oil station and a guide rail 10. The guide rail 10 is arranged on the base 1 along the axial direction of the belt reel 6. Slide blocks 18 are slidably arranged on both ends of the guide rail 10. The lifting hydraulic cylinder 3 is vertically arranged on the two slide blocks 18. The piston rod of the lifting hydraulic cylinder 3 is connected to the bottom of the platform 17. Guide rods 19 are respectively arranged on the base 1 on both sides of each lifting hydraulic cylinder 3. The guide rods 19 longitudinally pass through the platform 17 and are slidably connected to the platform 17. A winding mechanism is set on the top of the platform 17. When the lifting hydraulic cylinder 3 is lifted, the distance between the platform 17 and the base 1 is changed, thereby adjusting the length of the belt to be wound in. Therefore, when winding the belt, it is not restricted by the length of the belt; the guide rods 19 are on both sides of the lifting hydraulic cylinder 3, which can prevent the lifting hydraulic cylinder 3 from tilting due to unbalanced force when lifting. When the belt is wound, the slide block 18 drives the lifting hydraulic cylinder 3 to move to both sides along the guide rail 10, so that the winding mechanism is disengaged from the platform, which can be more convenient for subsequent manual operations. A hydraulic oil station is arranged on the base, and the hydraulic oil station is connected to the lifting hydraulic cylinder 3 through a hose to provide power for the lifting hydraulic cylinder 3.

[0021] See also Figure 1 A traction belt 7 is added to the belt reel 6, one end of the traction belt 7 is connected to the central shaft 16, and the other end is fixed with a belt clamp 8, and the traction belt 7 is provided with 2-3 pieces; the belt clamp 8 is arranged parallel to the central shaft 16, and the belt clamp 8 is provided with a fixing bolt 9. The arrangement of the traction belt 7 and the belt clamp 8 can drive the belt to be rolled better when the equipment is started, and the belt will not fall off at the initial stage of rolling.

[0022] When in use, the end of the belt is fixed to the belt clamp plate 8 with a fixing bolt 9, and the belt is connected to the belt drum 6 through the traction belt 7. After the belt is fixed, the hydraulic motor 2 is started to drive the belt drum 6 to rotate, and the belt is rolled into the belt drum 6 as it rotates. At the same time, the length of the rolled belt can be adjusted by lifting the lifting hydraulic cylinder 3. After the belt is rolled, the lifting hydraulic cylinder 3 is lowered to make the rolled belt contact the base 1, and the lifting hydraulic cylinder 3 moves to the outside of the base 1 along the guide rail 10, so that the two ends of the central axis 16 of the belt drum 6 are disengaged from the hydraulic motor 2, and then the adjustment nuts 14 at both ends of the central axis 16 are loosened outward, and the connecting plate 13 slides outward along the central axis 16, so that the angle between the connecting rod 12 and the connecting plate 13 becomes smaller, and the distance between the support plate 11 and the central axis 16 becomes smaller, so that the support plate 11 is separated from the belt. After the belt is separated, the fixing bolts 9 on the belt clamp plate 8 are loosened to take out the belt drum 6, and the belt rolling is completed. The belt drum 6 is reinstalled on the hydraulic motor 2 for the next belt rolling.

[0023] In order to prevent the belt reel 6 from sliding inwards during use, adjusting nuts 14 can be installed on both sides of the connecting plate 13 for bidirectional braking.
