Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyor maintenance, in particular to an inflatable belt conveyor idler replacement device. Background Art

[0002] Belt conveyors (i.e., belt machines) are used to transport various bulk goods, and have the advantages of simple structure, convenient use, continuous operation, long transportation distance, etc. They are widely used in industrial and mining enterprises, ports, stations, transportation yards and other units for transporting materials.

[0003] The structure of a belt conveyor consists of a frame, an idler support, idlers, a belt, drums, a motor and a reducer. The frame is a long steel frame, and multiple idler supports are fixedly installed in sequence along the length direction of the frame. Idlers are installed on the idler supports, the belt is placed above the idlers, the drums are located at both ends of the frame respectively, the motor and the reducer are connected to the drums, and the belt surrounds the drums at both ends of the frame. When in use, the motor and the reducer drive the drums to rotate, and the drums drive the belt to move on the idlers. During the use of the belt conveyor, due to continuous long-term operation, the idlers are worn and need to be replaced regularly. The idler support under the idler of the traditional belt conveyor is composed of a base, columns, tie rods and a lower bracket welded together. The idler shafts at both ends of the idler are respectively stuck in the idler shaft installation grooves at the upper ends of the columns and the lower bracket. When the idler needs to be replaced, the idler can only be removed and installed from above the idler support, so the belt needs to be lifted to remove the idler. However, the belt is heavy. For example, a 2-meter-wide steel wire belt weighs up to 60 KG per meter. When replacing the idler, a crane is required to lift the belt away from the idler to a certain height, and then the idler is replaced.

[0004] The inventor found in the implementation process that there are at least the following defects in the above-mentioned prior art: due to the large weight of the belt, a lifting device is required to lift it when replacing the idler, so the operation efficiency is low, and it is easily restricted by the site space. Summary of the Utility Model

[0005] The embodiment of the present application provides an inflatable belt conveyor idler replacement device, which solves the problem of low operation efficiency when replacing the idler of the belt conveyor at present, and is not restricted by space and is convenient to operate.

[0006] To solve the above technical problems, the utility model adopts the following technical scheme. An inflatable belt conveyor idler replacement device includes a rigid groove that can be installed on the belt conveyor frame and an airbag located in the rigid groove. The rigid groove includes a first trough-shaped structure and a second trough-shaped structure. The second trough-shaped structure can be folded or unfolded relative to the first trough-shaped structure. After the second trough-shaped structure is unfolded relative to the first trough-shaped structure, the airbag is inflated, and the airbag can lift the belt.

[0007] When replacing the idler of the belt conveyor with the aid of this device, the rigid groove is unfolded and installed on the frame of the belt conveyor. Since there is an airbag in the rigid groove, the belt of the belt conveyor can be lifted by inflating the airbag. Therefore, it is not necessary to use a lifting device to lift the belt, and the belt can be lifted to a certain height, and then the idler can be replaced. The operation is convenient and not restricted by the site space.

[0008] Further, both the first trough-shaped structure and the second trough-shaped structure include a bottom plate and a wing plate. The bottom plate of the first trough-shaped structure is movably connected to the bottom plate of the second trough-shaped structure through a connecting plate. Among them, both ends of the connecting plate in the length direction are respectively connected to one end of the bottom plate of the first trough-shaped structure and one end of the bottom plate of the second trough-shaped structure through hinges. Thus, the second trough-shaped structure can be folded or unfolded relative to the first trough-shaped structure. When the device is not in use, it can be folded into a smaller volume for easy storage and transportation. At the same time, when in use, it can be quickly unfolded into the required working state for easy operation.

[0009] Further, the sum of the widths of the wing plates of the first trough-shaped structure and the wing plates of the second trough-shaped structure is equal to the length of the connecting plate. Thus, it can be ensured that when the second trough-shaped structure is folded relative to the first trough-shaped structure, the two can fit closely to form a compact box-shaped structure, which is convenient for the storage and transportation of the device.

[0010] Further, the rigid groove further includes a stress strengthening plate. The length of the stress strengthening plate is greater than the length of the connecting plate, and both ends of the stress strengthening plate can be respectively fixed to the wing plates of the first trough-shaped structure and the wing plates of the second trough-shaped structure. Thus, the anti-bending ability of the rigid groove can be enhanced to ensure that the whole device can maintain a stable structural form during the process of the airbag inflating to lift the belt.

[0011] Further, a handle is fixed to the wing plate of the first trough-shaped structure or the wing plate of the second trough-shaped structure.

[0012] Further, the bottom of the airbag is located at the bottom of the rigid groove, and an air pump and an air release valve are installed on one side or one end of the airbag.

[0013] It can be seen from the above technical solutions that the utility model has at least the following technical effects or advantages:

[0014] 1. When replacing the idler of the belt conveyor with the aid of this device, the rigid groove is unfolded and installed on the frame of the belt conveyor. Since there is an airbag in the rigid groove, the belt of the belt conveyor can be lifted by inflating the airbag. Therefore, it is not necessary to use a lifting device to lift the belt, and the belt can be lifted to a certain height, and then the idler can be replaced. The operation is convenient and not restricted by the site space;

[0015] 2. The bottom plate of the first trough-shaped structure is connected to the bottom plate of the second trough-shaped structure through a connecting plate, so that the second trough-shaped structure can be folded or unfolded relative to the first trough-shaped structure. When the device is not in use, it can be folded into a smaller volume for easy storage and transportation. At the same time, when in use, it can be quickly unfolded into the required working state for easy operation. Brief Description of the Drawings

In one example, the rigid groove is fixed on the frame of the belt conveyor and is located below the belt, and the notch of the rigid groove faces upward. The bottom of the airbag 1 is located at the bottom of the rigid groove, and an air pump 10 and a deflation valve 11 are installed on one side or one end of the airbag 1. After the airbag 1 is inflated, the airbag 1 can lift the belt.

[0026] In this embodiment, the rigid groove comprises a first trough-shaped structure 2 and a second trough-shaped structure 3, and the second trough-shaped structure 3 can be folded or unfolded relative to the first trough-shaped structure 2.

[0027] Both the first trough-shaped structure 2 and the second trough-shaped structure 3 comprise a bottom plate 4 and wing plates 5. The bottom plate 4 can contact the frame of the belt conveyor, and the wing plates 5 are located on both sides of the bottom plate 4 and are perpendicular to the bottom plate 4, thereby forming a groove for accommodating the airbag 1. The bottom plate 4 of the first trough-shaped structure 2 is movably connected to the bottom plate 4 of the second trough-shaped structure 3 through a connecting plate 6. As Figure 2 、 Figure 3 shown, both ends of the connecting plate 6 are respectively connected to one end of the bottom plate 4 of the first trough-shaped structure 2 and one end of the bottom plate 4 of the second trough-shaped structure 3 through hinges 7, thereby enabling the second trough-shaped structure 3 to be folded or unfolded relative to the first trough-shaped structure 2. During the use of the utility model, the second trough-shaped structure 3 needs to be unfolded relative to the first trough-shaped structure 2, the opening of the rigid groove is kept upward, and then the airbag 1 is inflated.

[0028] Specifically in this embodiment, the rigid groove further comprises a force-bearing reinforcement plate 8. As Figure 3 shown, there are two force-bearing reinforcement plates 8. The length of the force-bearing reinforcement plate 8 is greater than the length of the connecting plate 6, and both ends of the force-bearing reinforcement plate 8 can be fixed to the wing plates 5 of the first trough-shaped structure 2 and the second trough-shaped structure 3 respectively. After the second trough-shaped structure 3 is unfolded relative to the first trough-shaped structure 2, the first trough-shaped structure 2 and the second trough-shaped structure 3 can form a flat trough with an upward opening through the force-bearing reinforcement plate 8, and the rigid groove has strong anti-bending ability.

[0029] In addition, the sum of the widths of the wing plates 5 of the first trough-shaped structure 2 and the widths of the wing plates 5 of the second trough-shaped structure 3 is equal to the length of the connecting plate 6, thereby enabling the second trough-shaped structure 3 to be folded relative to the first trough-shaped structure 2, and enabling the two to form a box-shaped structure after folding. A handle 9 is also fixed on the wing plate 5 of the first trough-shaped structure 2 or the second trough-shaped structure 3, thereby facilitating the device to be taken when it is folded.

[0030] When the idler of the belt conveyor needs to be replaced, the operator can take this device to the position of the idler to be replaced, open the second trough-shaped structure 3 relative to the first trough-shaped structure 2, and fix both ends of the force strengthening plate 8 to the first trough-shaped structure 2 and the second trough-shaped structure 3 respectively. Then make the bottom surface of the first trough-shaped structure 2 and the bottom surface of the second trough-shaped structure 3 contact with the frame of the belt conveyor, inflate the airbag 1 through the air pump, lift the belt after the airbag 1 expands, and finally replace the idler.
