Description

Technical Field

[0001] This utility model relates to the technical field of mining conveying equipment, specifically to a belt lifting device for a belt conveyor. Background Technology

[0002] Belt conveyors are widely used in mining machinery. Idler rollers are an important component of belt conveyors. Due to material impact and mechanical wear, idler rollers wear out very quickly and need to be replaced frequently to maintain the normal operation of the belt conveyor.

[0003] Traditional manual replacement methods suffer from significant drawbacks, including high manpower requirements, high safety risks, and low operational efficiency. With the strict implementation of regulations such as the "Production Safety Law," enterprises need to reduce high-risk manual operations. Simultaneously, continuous production industries require equipment maintenance to minimize downtime and improve work efficiency.

[0004] In the prior art, there is a patent with publication number CN218840686U and patent name: A conveyor belt lifting device. In this patent document, a support part, a grip part and a buckle are provided. When the user holds the grip part and extends it outward, the support part tilts upward at a certain angle, contacts the belt and lifts it up.

[0005] When using this patent, the belt is usually lifted to a certain height from one side, and this requires operation. The conveyor belt is generally quite heavy, and if one side is lifted upwards, the force-bearing area is too small, which can easily cause cracks. In addition, the bottom idler rollers are also quite heavy, and they need to be raised a certain distance when replacing them. If only one side of the belt is lifted, the idler rollers will still be under pressure, which can easily cause interference during replacement and affect subsequent operations. Utility Model Content

[0006] To overcome the above-mentioned defects, the purpose of this utility model is to provide a belt lifting device for belt conveyors, which lifts the conveyor belt through a lifting beam to meet the needs of replacing idlers.

[0007] To achieve the above objectives, this utility model provides a belt lifting device for a belt conveyor, characterized in that it includes a base, on which a lifting beam is provided; the base is also provided with a drive screw.

[0008] A support plate and a power plate are provided between the lifting beam and the base. The lower end of the support plate is hinged to the base, and the upper end of the support plate is slidably connected to the lifting beam. The power plate is provided with a screw slider that is connected to the drive screw.

[0009] The lifting beam is also provided with a support plate and an auxiliary support plate. One end of the support plate is hinged to the lifting beam, and the upper end of the auxiliary support plate is hinged to the support plate. The auxiliary support plate is provided with multiple angle adjustment slots, and one of the angle adjustment slots is engaged with the lifting beam.

[0010] Under the power of the drive screw, the lifting beam moves to a height greater than the end face height of the idler roller assembly.

[0011] Preferably, the base is provided with a base limiting groove, and a lower roller is provided in the base limiting groove; the lifting beam is provided with a beam limiting groove, and an upper roller is provided in the beam limiting groove.

[0012] The upper ends of the power plate and the support plate, located on the same side, are hinged to the same upper roller; the lower end of the power plate is hinged to the lower roller.

[0013] Preferably, the base limiting groove and the crossbeam limiting groove have the same width, and the lower roller and the upper roller have the same model.

[0014] Preferably, the lifting beam is provided with multiple pallet adjustment holes, and the lower end of the support plate is hinged to one of the pallet adjustment holes by a pin.

[0015] Preferably, the length of the lifting beam is less than the length of the base.

[0016] The beneficial technical effects achieved by this utility model after adopting the above technical solution are as follows:

[0017] 1. A lifting beam is installed on the base, and the lifting height is controlled by a transmission screw that moves a slider, thus lifting the conveyor belt and facilitating the replacement of the belt idlers. The lifting beam also features support plates and auxiliary support plates. The angle of the auxiliary support plates can be adjusted via an angle adjustment slot to accommodate and hold conveyor belts at different inclination angles. During lifting, the lifting beam supports the bottom of the conveyor belt, while the support plates on both sides support the sides, resulting in a larger force-bearing area. The conveyor belt rises and falls vertically, with only a significant change in height, minimizing deformation and thus preserving its lifespan. Removing and placing the idlers is also more convenient. After replacing the idlers, the belt is lowered vertically, preventing serious belt misalignment due to inaccurate positioning.

[0018] 2. Because of the base limiting groove and the crossbeam limiting groove, and the upper and lower rollers for movement, even if there are a certain amount of impurities in the base limiting groove or the crossbeam limiting groove during the movement, the entire movement process will not be affected. Therefore, lifting can still be achieved, making installation and maintenance more convenient. Compared with the traditional slider movement method, the required precision is lower, making it especially suitable for complex working conditions downhole.

[0019] 3. The base and the lifting beam are each composed of two hot-rolled U-shaped steels of the same model. Hot-rolled U-shaped steels are widely used in mine support. As needed, holes are drilled at appropriate locations and bolts are used for fixing. Therefore, no additional purchase is required, which can reduce costs. Disassembly, installation and movement are also relatively simple. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0030] See Figures 1-5This utility model provides a belt lifting device for a belt conveyor, including a base 1, on which a lifting beam 2 is mounted; a drive screw 11 is also mounted on the base 1; a support plate 22 and a power plate 21 are arranged between the lifting beam 2 and the base 1, the lower end of the support plate 22 is hinged to the base 1, and the upper end of the support plate 22 is slidably connected to the lifting beam 2; a screw slider connected to the drive screw 11 is mounted on the power plate 21; a support plate 23 and an auxiliary support plate 24 are also provided on the lifting beam 2, one end of the support plate 23 is hinged to the lifting beam 2, and the upper end of the auxiliary support plate 24 is hinged to the support plate 23; the auxiliary support plate 24 is provided with multiple angle adjustment grooves 241, and one of the angle adjustment grooves 241 is engaged with the lifting beam 2; under the power of the drive screw 11, the movement height of the lifting beam 2 is greater than the end face height of the idler roller group 4. This utility model is generally used to lift the conveyor belt 3 between two adjacent idler roller groups 4. Place the base 1 between the two idler roller groups 4 and adjust it to the center position. Based on the width of the conveyor belt 3, first adjust the tilt angle of the pallet 23, generally making it parallel to the conveyor belt 3. The adjustment method involves hinged one end of the pallet 23 to the corresponding pallet adjustment hole 27. In this invention, the hinge shaft is generally a long bolt. Next, adjust the angle of the auxiliary support plate 24. The auxiliary support plate 24 is used for support, ensuring that the angle of the pallet 23 does not change. One end of the auxiliary support plate 24 is hinged to the lifting beam 2, and the other end's angle adjustment groove 241 is engaged with a bolt. Generally, there are two angle adjustment grooves 241. After adjustment, the tilt angle of the pallet 23 is almost parallel to the conveyor belt 3. After installation, the drive screw 11 on one side is driven manually or electrically, causing the power plate 21 to move towards the center of the base 1. The height of both the power plate 21 and the support plate 22 gradually increases, forcing the lifting beam 2 to move upwards, supporting the conveyor belt 3. Generally, two sets of drive screws 11 are installed, with synchronized adjustments on both sides to ensure smooth lifting. After lifting to a certain height, other auxiliary equipment is used to replace the corresponding idler roller group 4.

[0031] The base 1 of this utility model is provided with a base limiting groove 12, and a lower roller 13 is provided in the base limiting groove 12; the lifting beam 2 is provided with a beam limiting groove 25, and an upper roller 26 is provided in the beam limiting groove 25; the upper ends of the power plate 21 and the support plate 22 located on the same side are hinged to the same upper roller 26; the lower end of the power plate 21 is hinged to the lower roller 13. Due to the harsh environment in the mine, the lower roller 13 is provided in the base limiting groove 12 and the upper roller 26 is provided in the beam limiting groove 25 to reduce friction and ensure stable lifting.

[0032] In this invention, the base limiting groove 12 and the crossbeam limiting groove 25 have the same width, and the lower roller 13 and the upper roller 26 are of the same model. Both the base 1 and the lifting crossbeam 2 are constructed from the same type of hot-rolled U-shaped steel, and the lower roller 13 and the upper roller 26 are also of the same model. Therefore, only drilling and fixing with fastening bolts according to the position are required. Generally, the fastening bolts should be of high strength and can also be used as pins. Hot-rolled U-shaped steel is a standard component in the mining machinery industry.

[0033] The lifting beam 2 of this utility model is provided with multiple pallet adjustment holes 27, and the lower end of the support plate 22 is hinged to one of the pallet adjustment holes 27 by a pin. The conveyor belt 3 and the idler roller group 4 are generally of two types, and can be hinged to different pallet adjustment holes 27 according to different widths.

[0034] The base 1 and lifting beam 2 of this invention are each composed of two identical hot-rolled U-shaped steel sections, or lightweight aluminum alloy can be used. The length of the lifting beam 2 is less than the length of the base 1. The slightly shorter length of the lifting beam 2 results in a lighter weight during lifting, and it is driven by a drive screw 11 to move the power plate 21. Hot-rolled U-shaped steel is more readily available, and although it is heavier, it can be used without customization.

[0035] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
