Description

Technical Field

[0001] This utility model relates to the field of belt replacement technology for belt conveyors, and in particular to an industrial belt replacement unit. Background Technology

[0002] The conveyor belt of a belt conveyor is used to transport materials. During use, the conveyor belt will wear out or even break due to long-term friction with the materials. Therefore, it is necessary to replace the conveyor belt in time. In the existing technology, the old belt is usually cut off and a new belt is installed. The cut old belt falls directly to the ground, affecting the movement of vehicles and cranes. It needs to be cleaned and collected manually, which is time-consuming, labor-intensive, cumbersome and inefficient.

[0003] Patent document CN115771793A discloses a device for replacing the belt of a belt conveyor. A new belt is wound on a first drum. The conveyor belt replacement vehicle is moved to the vicinity of the near-end roller of the belt conveyor. One end of the new belt is fixed to the old belt, the old belt is cut, and one end of the old belt is connected to a second drum via a steel wire rope. A first drive mechanism and a second drive mechanism operate. The first drum releases the new belt, and the second drum winds up the old belt. When the end of the new belt connected to the old belt moves to the near-end roller, the new belt is separated from the old belt. The old belt continues to be wound up by the second drum, the new belt is cut, and both ends of the new belt are fixed, completing the belt replacement of the belt conveyor. In implementing this technical solution, the inventors discovered at least the following problems in the prior art:

[0004] In actual use, the above-mentioned device connects one end of the old belt to the second drum via a steel wire rope, and the other end of the old belt to the new belt on the first drum. When the first drum and the second drum are in motion, the new belt replaces the old belt and is installed on the conveyor roller, while the old belt is wound around the second drum. However, there are still problems with the installation and removal of the first drum and the second drum. This makes it inconvenient to install the new belt on the first drum and remove the old belt wound around the second drum. At the same time, when the old belt is wound on the second drum, it cannot be effectively fixed and is prone to loosening during winding, making it inconvenient to use.

[0026] Furthermore, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0027] See Figures 1-3 An industrial belt replacement unit includes a movable base 1, a fixed frame 2 fixedly connected to the top of the movable base 1, mounting components 3 on both sides of the inner wall of the fixed frame 2, a first roller 4 and a second roller 5 respectively mounted on the mounting components 3, a movable frame 6 slidably connected to the top of the fixed frame 2, and a pair of pressure rollers 7 below the movable frame 6.

[0028] The fixed frame 2 is moved to one end of the conveyor via the movable seat 1. The new belt is installed on the first roller 4 via the mounting assembly 3. The old conveyor belt is cut off, and one end of the old belt is fixedly connected to one end of the new belt on the first roller 4. The other end of the old belt is connected to the second roller 5 via a steel wire rope. The first roller 4 and the second roller 5 start to rotate, causing the new belt to move onto the conveyor. The old belt is wound around the second roller 5. During winding, the movable frame 6 is moved above the second roller 5, so that a pair of pressure rollers 7 come into contact with the outside of the old belt to press and limit the old belt, making the old belt more tightly wound. After the two ends of the new belt are attached, they separate from the old belt and are fixed at both ends, completing the replacement of the new belt. At this time, the old belt is also completely wound around the second roller 5. Finally, the second roller 5 is disassembled via the mounting assembly 3 to recycle the old belt.

[0029] In the specific implementation process, such as Figure 2 As shown, the installation component 3 includes a pair of fixing blocks 31 fixedly disposed on both sides of the inner wall of the fixing frame 2. A rotating rod 32 is rotatably disposed on the top of the fixing block 31. Both ends of the rotating rod 32 are provided with snap-fit ​​grooves 33. A fixing ring 34 is disposed on the top of the fixing block 31. A pair of fixing bolts 35 are disposed inside the fixing ring 34.

[0030] The first roller 4 and the second roller 5 are fixed on the rotating rod 32. The fixing block 31 supports both ends of the rotating rod 32. The fixing ring 34 is fixed to the top of the fixing block 31 by the fixing bolt 35 to limit the rotation rod 32, thereby facilitating the installation and removal of the first roller 4 and the second roller 5 on the rotating rod 32.

[0031] One end of the rotating rod 32 is respectively provided with a first synchronous pulley 8 and a second synchronous pulley 9, and the first synchronous pulley 8 and the second synchronous pulley 9 are connected by a synchronous belt.

[0032] A motor 10 is fixedly connected to one side of the fixed frame 2, and the output end of the motor 10 is engaged with the locking groove 33 at one end of the rotating rod 32.

[0033] The shafts of the first synchronous pulley 8 and the second synchronous pulley 9 are engaged with the slot 33 at one end of the rotating rod 32 via a rotating shaft. The output end of the motor 10 is engaged with the slot 33 at the other end of the rotating rod 32 via a rotating shaft. The motor 10 drives the rotating rod 32 inside the first roller 4 to rotate, which in turn drives the first synchronous pulley 8 to rotate the second synchronous pulley 9. Thus, the single motor 10 simultaneously drives the first roller 4 and the second roller 5 to rotate.

[0034] The inner walls of the movable frame 6 are fixedly connected to sliders 11 on both sides. The fixed frame 2 has grooves 12 on both sides that cooperate with the sliders 11. When the movable frame 6 moves, the sliders 11 slide in the grooves 12 to guide and limit the movable frame 6, thereby improving the stability of the movable frame 6 when it moves.

[0035] Lifting rods 13 are slidably connected to both sides of the inner wall of the movable frame 6. A fixed frame 14 is fixedly connected to one side of the lifting rod 13. The two ends of the pressure roller 7 are rotatably connected to the inner wall of the fixed frame 14 through a rotating shaft. Multiple springs 15 are provided on the top of the fixed frame 14. The top of the springs 15 is fixedly connected to the inner wall of the movable frame 6. The pressure roller 7 is supported by the fixed frame 14. The pressure roller 7 is given elasticity by pressing down on the fixed frame 14 through the springs 15. As the thickness of the old belt gradually increases during winding, the lifting rods 13 on both sides of the fixed frame 14 rise on the inner wall of the movable frame 6 to ensure that the pressure roller 7 can always be in close contact with the outside of the old belt.

[0036] In use, the first roller 4 and the second roller 5 are fixed on the rotating rod 32. The fixing block 31 supports both ends of the rotating rod 32. The fixing ring 34 is fixed to the top of the fixing block 31 by the fixing bolt 35 to limit the rotation rod 32, thereby facilitating the installation and removal of the first roller 4 and the second roller 5 on the rotating rod 32. The fixing frame 2 is moved to one end of the conveyor by the moving seat 1. The new belt is installed on the first roller 4. The old belt of the conveyor is cut off, and one end of the old belt is fixedly connected to one end of the new belt on the first roller 4. The other end of the old belt is connected by a steel wire. The rope is connected to the second roller 5, and the first roller 4 and the second roller 5 start to rotate, moving the new belt onto the conveyor. The old belt is wound around the second roller 5. During winding, the moving frame 6 is moved above the second roller 5, so that a pair of pressure rollers 7 contact the outside of the old belt, pressing and limiting the old belt, making the old belt more tightly wound. After the two ends of the new belt are attached, they separate from the old belt, and the two ends of the new belt are fixed, completing the replacement of the new belt. At this time, the old belt is also completely wound around the second roller 5. Finally, the second roller 5 is disassembled to recycle the old belt.
