[0029] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0030] Example 1

[0031] Please refer to Figures 1-3 This utility model provides a device for quickly disassembling belt conveyor rollers, including a movable iron plate 1 with rollers at the bottom, a fixed seat 2 welded to the upper end of the movable iron plate 1, and two sets of lifting mechanisms installed on the fixed seat 2.

[0032] The lifting mechanism includes a pair of support rods 3 hinged to the fixed base 2. The upper ends of the pair of support rods 3 are respectively hinged to support rods 4. The upper ends of the pair of support rods 4 are hinged to the lower ends of the support rods 7. A connecting block 5 is connected between the connection points of two adjacent support rods 3 and support rods 4. The rotating rods on both sides of the connecting block 5 are rotatably connected to the two sets of support rods 3 and support rods 4 respectively. At the same time, a double-acting screw 6 passes through the connecting block 5 and is threadedly connected to the connecting block 5. Rotating the double-acting screw 6 causes the two connecting blocks 5 to move towards each other, thereby causing the two support rods 3 and support rods 4 to slide inward, so that the lifting mechanism can achieve the lifting function.

[0033] A support rod 7 is connected to the end of the lifting mechanism. The support rod 7 has a cross-shaped structure, and a rotating wheel 8 is rotatably installed at the upper end of the support rod 7. The support rod 7 is inserted under the idler roller. The double screw 6 is rotated by shaking the handle of the device, which in turn lifts the support rod 7. As the support rod 7 supports the belt above the device, the idler roller is also lifted and removed. The whole process can be completed by only one person, and there is no safety risk in the operation.

[0034] Example 2

[0035] like Figures 4 to 8 As shown, a support base 9 is fixed to one side of the movable iron plate 1 by bolts. An adjusting rod 10 is slidably installed on the inner side of the support base 9. A top plate 13 is fixedly installed at the upper end of the adjusting rod 10. At the same time, symmetrical sliding grooves 14 are opened on the top plate 13. An installation plate 16 is slidably installed in the sliding grooves 14. An air bag 20 is installed on the upper side of the installation plate 16. The air bag 20 is connected to the air outlet of the air pump 22 through a pipe. An exhaust port is opened on one side of the air bag 20. For some conveyors where it is inconvenient to insert the support rod 7, this embodiment can be used to assist in the disassembly of the idler roller. Since the support base 9 is located on one side of the movable iron plate 1, the height of the adjusting rod 10 can be adjusted according to the height of the conveyor so that the top plate 13 is located at the edge of the conveyor. Then, the installation plate 16 is slid into the underside of the belt. The air pump 22 is used to inflate the air bag 20. After the air bag 20 expands, it lifts the belt.

[0036] Furthermore, symmetrical sliding holes 17 are provided on the lower side of the mounting plate 16. A push plate 19 is slidably installed in the sliding holes 17. One end of the push plate 19 is connected to the mounting plate 18. An airbag 21 is installed on the upper side of the mounting plate 18. According to the width of the belt, the push plate 19 is pushed, so that the mounting plate 18 moves with the airbag 21 to the other side of the belt, which can accelerate the speed and stability of belt lifting.

[0037] An exhaust port is provided on the second airbag 21. The first airbag 20 and the second airbag 21 are connected by a pipe. The first airbag 20 and the second airbag 21 can be inflated by the air pump 22.

[0038] To improve the stability of the top plate 13 after it moves, a through groove 11 is provided on one side of the support base 9. A protrusion on one side of the support base 9 slides in the through groove 11. An adjusting screw 12 is rotatably provided on one side of the through groove 11. The protrusion is threadedly connected to the adjusting screw 12, so that the adjusting rod 10 can be stably raised and lowered by rotating the adjusting screw 12.

[0039] It is worth noting that a slot 15 is provided on the lower side of one end of the top plate 13. When the top plate 13 is raised to the edge of the conveyor, the slot 15 can be engaged with the edge to increase the support strength of the top plate 13.

[0040] In summary, the working principle of the device for quickly disassembling belt conveyor idlers according to this utility model embodiment is as follows: a mechanical lifting mechanism is welded onto a movable iron plate 1 with rollers installed at the bottom, and a cross-shaped support rod 7 with rollers is welded onto the top of the lifting mechanism. The support rod 7 is inserted under the idler. By rotating the double-acting screw 6, the lifting mechanism pushes the support rod 7 upward. While the support rod 7 supports the belt, the idler is also lifted and disassembled. The whole process can be completed by only one person, and there is no safety risk in the operation process.

[0041] By moving the adjusting rod 10 upward, the top plate 13 is positioned at the upper end of the belt conveyor frame. It is then engaged with the frame using the slot 15. The mounting plate 16 is pushed to allow the airbags 20 and 21 to enter the underside of the belt. The push plate 19 is then pushed to move the mounting plate 18 inward, positioning the airbag 21 on the other side of the belt. The air pump 22 inflates the airbags 20 and 21, lifting the belt upward, thus facilitating the disassembly of the idler rollers. This allows for the disassembly of different types of belt conveyor idler rollers in two different ways.

[0042] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
