Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, and in particular to a roller protection device for belt conveyors. Background Technology

[0002] In industrial production, belt conveyors, as core equipment for material handling, are widely used in mining, metallurgy, and manufacturing. They primarily rely on rollers to drive the conveyor belt to transport materials, and the stable operation of the rollers and conveyor belt directly affects the overall conveying efficiency and equipment lifespan.

[0003] Traditional belt conveyors typically have fixed connections between the rollers and the frame. When the rollers wear out or the conveyor belt ages and needs to be replaced, a large number of bolts need to be removed, which is cumbersome and time-consuming, seriously affecting production progress. Furthermore, most conveyors lack dedicated protective structures, leaving the rollers and conveyor belt directly exposed to the outside environment, making them susceptible to the intrusion of external debris, which can lead to conveyor belt jamming and accelerated roller wear. Utility Model Content

[0004] In the existing technology, the rollers and frame of traditional belt conveyors are mostly fixedly connected. When the rollers wear out or the conveyor belt ages and needs to be replaced, a large number of bolts need to be removed, which is cumbersome and time-consuming, seriously affecting the production progress. In addition, most conveyors lack a special protective structure, and the rollers and conveyor belts are directly exposed to the outside, making them susceptible to the intrusion of external debris, which can lead to conveyor belt jamming and accelerated roller wear. This utility model provides a roller protection device for belt conveyors.

[0005] The technical solution adopted by this utility model is: a roller protection device for a belt conveyor, including a mounting frame, the mounting frame including a first mounting plate and a second mounting plate, two symmetrical connecting plates integrally formed on both sides of the mounting frame, a roller is provided between the two connecting plates on the same side, a conveyor belt is provided on the surface between the two rollers, a first motor is fixedly installed on the surface of one side of the connecting plate, the output end of the first motor is fixedly connected to the roller on one side, a disassembly and assembly component for easy disassembly and assembly of the roller and the conveyor belt is installed inside the mounting frame, the disassembly and assembly component includes two symmetrical sliding rods fixedly installed on one side of the first mounting plate, and a protective component for easy protection of the conveyor belt and roller is installed on the top of the mounting frame. The disassembly and assembly component solves the problem of cumbersome disassembly and assembly of the roller and conveyor belt in traditional belt conveyors, greatly reducing the difficulty and time cost of maintenance; the protective component can effectively protect the conveyor belt and roller, reduce interference from external debris and the risk of accidental contact by personnel, and improve the safety and stability of equipment operation.

[0006] Furthermore, both sliding rods penetrate one side surface of the second mounting plate and are slidably connected to the second mounting plate. A limiting plate is fixedly installed at one end of each sliding rod, and the limiting plate is slidably connected inside the second mounting plate. A first spring is fixedly installed on the surface of each sliding rod. The sliding connection design between the sliding rod and the second mounting plate realizes the relative displacement adjustment between the first mounting plate and the second mounting plate, providing the necessary structural space for the assembly and disassembly of the roller.

[0007] Furthermore, the inner surface of the connecting plate is provided with mounting holes, and both ends of the two rollers are fixedly installed with rotating shafts that fit into the mounting holes. The rotating shafts are sleeved inside the mounting holes. The fitting design of the mounting holes on the connecting plate and the roller rotating shafts adopts a sleeve fit method, which not only ensures the coaxiality of the rollers when they rotate, reduces operating noise and wear, but also simplifies the installation and positioning process of the rollers.

[0008] Furthermore, the disassembly and assembly assembly also includes a push plate slidably connected to the second mounting plate. A second motor is fixedly mounted on one side of the first mounting plate, and a threaded rod is fixedly mounted on the output end of the second motor. The threaded rod is rotatably connected above the first mounting plate, and two moving blocks with opposite threads are threadedly connected to the surface of the threaded rod. A hinge rod is hinged to one side of each of the two moving blocks, and the other end of each of the two hinge rods is hinged to the middle position of one side of the push plate. The linkage design of the second motor, threaded rod, moving blocks and hinge rod in the disassembly and assembly assembly converts the rotational motion of the second motor into the linear motion of the push plate, realizing the automated adjustment of the second mounting plate.

[0009] Furthermore, the protective assembly includes a protective cover positioned above the mounting frame. Two symmetrical mounting frames are fixedly mounted on both sides of the mounting frame. A locking rod is slidably connected inside each mounting frame, penetrating one side of the mounting frame and slidably connected thereto. A sliding plate is fixedly mounted on one side of each locking rod, slidably connected inside the mounting frame. A second spring is fixedly mounted on one side of each sliding plate. Two symmetrical mounting rods are fixedly mounted on both sides of the protective cover, penetrating the upper surface of the mounting frame and slidably connected thereto. A groove is provided on one side of each mounting rod to mate with the locking rod. The protective cover effectively prevents external dust and debris from entering the contact area between the conveyor belt and the rollers, reducing equipment malfunctions caused by foreign object obstruction and extending the service life of the conveyor belt and rollers. The locking mechanism between the mounting frame, locking rod, and mounting rods enables quick installation and removal of the protective cover.

[0010] Furthermore, a third spring is fixedly installed inside the mounting frame, and a limiting block is fixedly installed above the third spring. The limiting block is slidably connected inside the mounting frame. Both the limiting block and the mounting rod are perpendicular to the snap-fit ​​rod. The limiting block moves to the snap-fit ​​block by the elastic force of the third spring to limit the snap-fit ​​block and facilitate the next installation.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model solves the problem of cumbersome disassembly and assembly of rollers and conveyor belts in traditional belt conveyors by disassembling and assembling components, which greatly reduces the difficulty and time cost of maintenance. It also solves the problem that in traditional belt conveyors, rollers and frames are mostly fixedly connected, and when rollers wear out or conveyor belts age and need to be replaced, a large number of bolts need to be removed, which is cumbersome and time-consuming and seriously affects the production progress.

[0013] 2. Secondly, the protective components of this utility model can effectively protect the conveyor belt and rollers, reduce interference from external debris and the risk of accidental contact by personnel, improve the safety and stability of equipment operation, and solve the problem that most conveyors lack a dedicated protective structure, leaving the rollers and conveyor belt directly exposed to the outside, making them susceptible to intrusion of external debris, which can lead to conveyor belt jamming, roller wear, and other problems.

[0022] The following is in conjunction with the appendix Figures 1-5 The present invention will be further described below.

[0023] In order to solve the problems existing in the background art, this application proposes the following technical solution: a roller protection device for belt conveyors.

[0024] The specific technical solution includes a mounting frame 1, which comprises a first mounting plate 101 and a second mounting plate 102. Two symmetrical connecting plates 2 are integrally formed on both sides of the mounting frame 1. Rollers 3 are positioned between the two connecting plates 2 on the same side, and a conveyor belt 4 is positioned on the surface between the two rollers 3. A first motor 5 is fixedly mounted on the surface of one connecting plate 2, and the output end of the first motor 5 is fixedly connected to one roller 3. The mounting frame 1 is internally equipped with a disassembly and assembly component 6 for easy disassembly and assembly of the rollers 3 and the conveyor belt 4. The disassembly and assembly component 6 includes two symmetrical sliding rods 601 fixedly mounted on one side of the first mounting plate 101. A protective component 7 is installed above the mounting frame 1 to protect the conveyor belt 4 and the rollers 3. The disassembly and assembly component 6 solves the problem of cumbersome disassembly and assembly of the rollers 3 and conveyor belt 4 in traditional belt conveyors, significantly reducing the operational difficulty and time cost during maintenance. The protective component 7 effectively protects the conveyor belt 4 and rollers 3, reducing interference from external debris and the risk of accidental contact by personnel, thus improving the safety and stability of equipment operation.

[0025] Reference Figures 1 to 3As shown, both sliding rods 601 penetrate one side surface of the second mounting plate 102 and are slidably connected to the second mounting plate 102. A limiting plate 602 is fixedly installed at one end of each sliding rod 601, and the limiting plate 602 is slidably connected inside the second mounting plate 102. A first spring 603 is fixedly installed on the surface of each sliding rod 601. A mounting hole 604 is provided on the inner surface of the connecting plate 2. Rotary shafts 605 that fit into the mounting holes 604 are fixedly installed at both ends of each of the two rollers 3, and the rotating shafts 605 are sleeved inside the mounting holes 604. The disassembly and assembly assembly 6 also includes a sliding... A push plate 606 is movably connected to the second mounting plate 102. A second motor 607 is fixedly mounted on one side of the first mounting plate 101. A threaded rod 608 is fixedly mounted on the output end of the second motor 607. The threaded rod 608 is rotatably connected above the first mounting plate 101. Two moving blocks 609 with opposite threads are threadedly connected to the surface of the threaded rod 608. A hinge rod 610 is hinged to one side of each of the two moving blocks 609. The other end of each of the two hinge rods 610 is hinged to the middle of one side of the push plate 606. When the second motor 607 is started, it drives the threaded rod 608 to rotate. Since there are two sections with opposite thread directions on the surface of the threaded rod 608, the two moving blocks 609 move towards or away from each other as the threaded rod 608 rotates. The movement of the moving blocks 609 is converted into linear motion of the push plate 606 through the hinge rods 610. When the push plate 606 moves away from the first mounting plate 101, it pushes the second mounting plate 102 to slide along the sliding rod 601, increasing the distance between the two plates. After the distance between the two plates increases, the rotating shaft 605 on one side of the roller 3 separates from the mounting hole 604 on the connecting plate 2, and the roller 3 and the conveyor belt 4 can be removed. Conversely, when the rotating shaft 605 of the roller 3 is aligned with the mounting hole 604, the second motor 607 reverses, causing the push plate 606 to move in the opposite direction by the elastic force of the first spring 603, reducing the distance between the two plates until the rotating shaft 605 is completely inserted into the mounting hole 604, thus completing the installation.

[0026] Reference Figure 1 , Figure 4 and Figure 5As shown, the protective assembly 7 includes a protective cover 701 mounted above the mounting frame 1. Two symmetrical mounting frames 702 are fixedly mounted on both sides of the mounting frame 1. A locking rod 703 is slidably connected inside the mounting frame 702, passing through one side of the mounting frame 702 and slidably connected to it. A sliding plate 704 is fixedly mounted on one side of the locking rod 703, slidably connected to the inside of the mounting frame 702. A second spring 705 is fixedly mounted on one side of the sliding plate 704. Two symmetrical mounting rods 706 are fixedly mounted on both sides of the protective cover 701, passing through the upper surface of the mounting frame 702 and slidably connected to it. A slot 707 that matches the locking rod 703 is provided on one side of the mounting rod 706. A third spring 708 is also fixedly mounted inside the mounting frame 702. A locking rod 705 is fixedly mounted above the third spring 708. A limiting block 709 is installed, which is slidably connected inside the mounting frame 702. Both the limiting block 709 and the mounting rod 706 are perpendicular to the snap-fit ​​rod 703. The mounting rods 706 on both sides of the protective cover 701 are inserted into the mounting frame 702. The mounting rods 706 press the limiting block 709, causing it to compress the third spring 708 and move downward. When the slot 707 of the mounting rod 706 is aligned with the snap-fit ​​rod 703, the second spring 705 pushes the sliding plate 704, causing the snap-fit ​​rod 703 to insert into the slot 707, locking the protective cover 701 onto the mounting bracket 1. Pulling the snap-fit ​​rod 703 upward causes it to disengage from the slot 707, releasing the lock on the mounting rod 706, and the protective cover 701 can be removed. At the same time, the limiting block 709 moves to one side of the snap-fit ​​rod 703 by the elastic force of the third spring 708 to limit the snap-fit ​​rod 703, facilitating the next installation of the protective cover 701.

[0027] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview:

[0028] In use, align the mounting rods 706 on both sides of the protective cover 701 with the mounting frame 702 on the mounting bracket 1. Insert the mounting rods 706 into the mounting frame 702 and press the limiting block 709. The limiting block 709 compresses the third spring 708 and moves downward. When the slot 707 of the mounting rod 706 aligns with the locking rod 703, the second spring 705 pushes the sliding plate 704, and the locking rod 703 inserts into the slot 707, locking the protective cover 701 onto the mounting bracket 1. Then, start the first motor 5 to drive the roller 3 to rotate, which in turn drives the conveyor belt 4 to transport materials. If it is necessary to disassemble the roller 3 and the conveyor belt 4, simply turn on the second motor 607 to drive the threaded rod 608 to rotate. The two moving blocks 609 on the threaded rod 608 move towards each other due to the opposite thread direction, pushing the push plate 606 away from the first mounting bracket 1 through the two hinge rods 610. As the mounting plate 101 moves in the direction of the push plate 606, the push plate 606 pushes the second mounting plate 102 to slide along the sliding rod 601, compressing the first spring 603. The distance between the first mounting plate 101 and the second mounting plate 102 increases, causing the connecting plates 2 on both sides to separate. When the distance between the two plates increases to a certain extent, the rotating shaft 605 of the roller 3 separates from the mounting hole 604, and the roller 3 and the conveyor belt 4 can be removed. Align the new roller 3 with the mounting hole 604 of the connecting plate 2, and put the new conveyor belt 4 on the two rollers 3. The second motor 607 reverses, and the two moving blocks 609 move towards each other. The hinge rod 610 pulls the push plate 606 to move towards the first mounting plate 101. Under the elastic force of the first spring 603, the second mounting plate 102 returns to its original position along the sliding rod 601, the distance between the two plates decreases, and the rotating shaft 605 of the roller 3 is fully inserted into the mounting hole 604, completing the installation.
