Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, specifically to a belt-driven bucket elevator anti-belt deviation mechanism. Background Technology

[0002] Currently, belt misalignment is a frequent problem during the operation of bucket elevators. Existing solutions include various mechanical, contact, and infrared anti-misalignment switches. For example, Chinese patent CN222592589U discloses an anti-misalignment switch for bucket elevators. A roller contacts the side edge of the bucket elevator belt. When the belt misaligns, it pushes the roller, which, in conjunction with other components, triggers the switch to shut down the bucket elevator and adjust the belt. However, in actual use, it has been found that the roller's constant contact with the belt easily leads to wear. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, this utility model provides a belt-type bucket elevator anti-belt deviation mechanism.

[0004] To achieve the above objectives, a belt-driven bucket elevator anti-belt misalignment mechanism is designed, comprising a frame shell, an installation cavity inside the frame shell, a movable plate on one side of the installation cavity, a wear-resistant movable block on one side of the movable plate, a sensing block connected to the upper end of the other side of the movable plate, an elongated sensing plate on one side of the sensing block, and warning position limit switches and stop position limit switches arranged vertically on one side of the sensing plate. A rotating component is provided between the lower end of the other side of the movable plate and the frame shell, and an L-shaped upper cover plate is provided at the upper end of the installation cavity. The bent edge of the upper cover plate is located on one side of the sensing block and is in contact with or separate from the sensing block.

[0005] The rotating component includes a hinge bushing, a flange bushing, an angle spring, a long bolt, and a nut. The front and rear sides of the lower end of the movable plate are respectively provided with hinge bushings, and an angle spring is provided between the hinge bushings on the front and rear sides. The front and rear sides of the frame shell are respectively provided with flange bushings that match the positions of the hinge bushings. The long bolt passes through the flange bushing on the front side of the frame shell, the hinge bushing on the front side of the movable plate, the angle spring, the hinge bushing on the rear side of the movable plate, and the flange bushing on the rear side of the frame shell in sequence and is fastened by a nut.

[0006] The frame shell is provided with mounting holes that cooperate with the warning position limit switch and the stop position limit switch.

[0007] The movable plate is provided with a sealing rubber gasket on one side, and the outer edge of the sealing rubber gasket is connected to the flange of the outer edge of the frame shell.

[0008] The sealing rubber gasket is provided with a through hole that mates with the wear-resistant movable block.

[0009] The lower part of one side of the frame shell is provided with an inclined surface, and a drainage hole is provided on the lower end of the frame shell connected to the inclined surface.

[0010] The wear-resistant movable block and the movable plate are detachably connected by bolts.

[0011] Compared with existing technologies, this invention avoids direct contact between the wear-resistant movable block and the bucket elevator belt, reducing wear. Furthermore, the wear-resistant movable block is replaceable, extending the overall service life of the device. The inclusion of warning and stop positions facilitates timely belt adjustment at the warning position, minimizing downtime. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] like Figures 1 to 4 As shown, the frame shell 1 has an installation cavity 1-12. A movable plate 3 is provided on one side of the installation cavity 1-12. A wear-resistant movable block 4 is provided on one side of the movable plate 3. The upper end of the other side of the movable plate 3 is connected to a sensing block 5. An extended sensing plate 5-1 is provided on one side of the sensing block 5. A warning position limit switch 6 and a stop position limit switch 7 are arranged vertically on one side of the sensing plate 5-1. A rotating part 8 is provided between the lower end of the other side of the movable plate 3 and the frame shell 1. An L-shaped upper cover plate 9 is provided at the upper end of the installation cavity 1-12. The bent edge of the upper cover plate 9 is located on one side of the sensing block 5 and is in contact with or separate from the sensing block 5.

[0019] The rotating component 8 includes a hinge bushing 8-1, a flange bushing 8-2, an angle spring 8-3, a long bolt 8-4, and a nut 8-5. The front and rear sides of the lower end of the movable plate 3 are respectively provided with hinge bushings 8-1, and the angle spring 8-3 is provided between the hinge bushings 8-1 on the front and rear sides. The front and rear sides of the frame shell 1 are respectively provided with flange bushings 8-2 that mate with the hinge bushings 8-1. The long bolt 8-4 passes through the flange bushing 8-2 on the front side of the frame shell 1, the hinge bushing 8-1 on the front side of the movable plate 3, the angle spring 8-3, the hinge bushing 8-1 on the rear side of the movable plate 3, and the flange bushing 8-2 on the rear side of the frame shell 1 in sequence and is fastened by the nut 8-5.

[0020] The frame housing 1 is provided with mounting holes 1-3 that cooperate with the warning position limit switch 6 and the stop position limit switch 7.

[0021] A sealing rubber gasket 10 is provided on one side of the movable plate 3. The outer edge of the sealing rubber gasket 10 is connected to the flange 1-2 of the outer edge of the frame shell 1, which ensures the sealing performance and isolates the vibration of the bucket elevator, thus extending its service life.

[0022] The sealing rubber gasket 10 is provided with a through hole 10-1 that mates with the wear-resistant movable block 4 for the movement of the wear-resistant movable block 4.

[0023] The lower part of one side of the frame shell 1 is provided with a slope 1-5, and the lower end of the frame shell 1 connected to the slope 1-5 is provided with a drainage hole 1-4, which ensures the discharge of condensate and dust inside in humid weather.

[0024] The wear-resistant movable block 4 and the movable plate 3 are detachably connected by bolts, which facilitates the replacement of the wear-resistant movable block 4.

[0025] When this utility model is in use, the bucket elevator belt 2 is running normally as follows: Figure 5 As shown at the bottom, there is a gap between the wear-resistant moving block 4 and the belt 2, preventing direct contact and reducing wear on the wear-resistant moving block 4. When the bucket elevator belt 2 deviates slightly, such as... Figure 5 As shown in the middle, belt 2 pushes wear-resistant movable block 4, which, under the action of rotating component 8, drives movable plate 3 and sensing block 5 to rotate. Sensing plate 5-1 of sensing block 5 approaches the warning limit switch 6. At this time, the stop limit switch 7 is not triggered, indicating a warning state, and a command is issued to adjust belt 2 back to its original position. When the bucket elevator belt 2 deviates significantly, such as... Figure 5 As shown at the top, when the sensing block 5 approaches the stop limit switch 7, the warning limit switch 6 remains in the triggered state, and the stop limit block 7 is triggered, indicating that the machine must be stopped to prevent an accident.

[0026] When assembling the rotating part 8, place the angle spring 8-3 between the hinge bushings 8-1 on the front and rear sides, and then place it into the frame housing 1. Insert the flange bushings 8-2 into both sides of the frame housing 1. After inserting the long bolts 8-4, lock them at the other end with nuts 8-5.

[0027] The bent edge of the L-shaped upper cover plate 9 and the sensing block 5 form a limiting and sealing mechanism. During the resetting process of the sensing block 5, the bent edge of the upper cover plate 9 is located on one side of the sensing block, which serves as a limiting function. After the sensing block 5 is reset, the sensing block 5 blocks the joint between the bent edge of the upper cover plate 9 and the movable plate 3, ensuring that dust will not enter the frame housing 1 during normal operation.
