Description

Technical Field

[0001] This utility model relates to the field of hoisting equipment, specifically a coal bucket hoisting machine. Background Technology

[0002] A hoist is a vertical conveying device that uses mechanical means to lift or lower materials, workpieces, or personnel in a vertical or steeply inclined direction. It is widely used in mining, construction, industrial production, logistics, and other fields to improve space utilization and operational efficiency. Hoists are the core equipment in the field of vertical conveying. Through mechanical or hydraulic power, combined with load-bearing and transmission structures, they meet the vertical material or personnel transportation needs of different industries and are indispensable equipment in modern industrial production and engineering construction.

[0003] A coal bucket elevator is a bucket elevator specifically designed for vertical coal transport. It is a key piece of equipment in the field of industrial material handling and is mainly used in coal mines, thermal power plants, coking plants, and other similar settings. It continuously lifts coal from a low position to a high position, such as a coal bunker or the feed inlet of processing equipment, to achieve efficient and automated vertical transport of coal. The motor drives the traction component (chain or belt) to rotate in a cycle. The coal bucket scoops up coal at the bottom feed inlet and rises to the top with the traction component. The coal is then unloaded into the target position by centrifugal force or gravity, completing the vertical transport.

[0004] When the coal bucket at one end of the existing coal bucket elevator is heavier, an off-center load torque will be generated during the lifting process. This will cause uneven stress on the frame, increased wear on transmission components, and even problems such as equipment shaking and decreased operating accuracy, thereby significantly reducing the stability of equipment operation and the service life of the equipment. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a coal bucket elevator to solve the technical problems mentioned in the background art.

[0037] The embodiments of this utility model will be described below based on its overall structure.

[0038] First embodiment: A coal bucket elevator, please refer to Figures 1-5 The equipment includes a lifting frame 1 and a coal bucket. A connecting frame 2 is installed at one end of the lifting frame 1, and a feeding platform 3 is set on the top of the connecting frame 2. A counterweight component 9 is set at one end of the feeding platform 3. The counterweight component 9 includes a positioning frame 90, a protrusion 91, and a groove 92. Multiple sets of limiting frames 93 are movably installed on the inner wall of the positioning frame 90, and a cavity 95 is sleeved on the inner wall of the limiting frame 93. By setting the counterweight component 9, the load on both sides of the feeding platform 3 can be balanced by adding the counterweight component 9 at one end of the feeding platform 3, which effectively improves the stability of the feeding platform 3 when it moves upward. This not only reduces the load on the drive system, but also greatly improves the operational stability and equipment life. With the setting of the first push rod 4 and the limiting plate 5, the first push rod 4 drives the limiting plate 5 to move upward. The limiting plate 5 is located at one end of the coal bucket and the counterweight component 9, respectively limiting the coal bucket and the counterweight component 9, which effectively improves the stability of the coal bucket and the counterweight component 9 when they move upward, thereby reducing the shaking generated by both.

[0039] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-3A second push rod 6 is provided at one end of the lifting frame 1, and a fixed block 7 is provided at the output end of the second push rod 6. The second push rod 6 drives the fixed block 7 to move, thereby causing the contact block 8 to adjust or push the position of the coal bucket, which effectively improves the practicality of the equipment.

[0040] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-3 A contact block 8 is provided at one end of the fixed block 7 near the coal bucket. The contact block 8 is arc-shaped and fits against the outer wall of the coal bucket. The shape of the contact block 8 facilitates its fit against the coal bucket and allows for targeted movement of the coal bucket, effectively improving the stability of the contact block 8 during movement.

[0041] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-3 The feeding platform 3 has a through hole 10, which is positioned opposite to the contact block 8. The through hole 10 facilitates the transfer of the coal bucket. The contact block 8 can push the coal bucket through the through hole 10 to allow it to be processed by other equipment, thereby effectively improving the practicality of the equipment.

[0042] For details regarding the above embodiments, please refer to [link / reference]. Figures 3-5 The inner wall of the positioning frame 90 is provided with multiple sets of grooves 92, and the limiting frame 93 is fitted in the grooves 92. The counterweight block 94 is movably installed in the cavity 95. The weight of the counterweight component 9 can be adjusted according to the weight of the coal bucket to balance the load on both sides of the discharge platform 3, effectively improving the stability of the discharge platform 3 when it moves upward.

[0043] For details regarding the above embodiments, please refer to [link / reference]. Figures 3-5 The bottom of the positioning frame 90 is provided with a protrusion 91, and the top of the feeding platform 3 is provided with a slide groove 11. The protrusion 91 and the slide groove 11 are engaged to facilitate the movement of the counterweight component 9, so that the counterweight component 9 is located at the top of the connecting frame 2 and the middle part of the feeding platform 3 when idle, which effectively improves the service life of the equipment.

[0044] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-5 The connecting frame 2 is located in the middle of the feeding platform 3, and the counterweight component 9 and the coal bucket are set opposite each other, which can not only reduce the load on the drive system, but also greatly improve the operational stability and equipment life.

[0045] Second embodiment: Please refer to Figures 1-3The difference between Embodiment 2 and Embodiment 1 is that, while retaining the features of Embodiment 1, a first push rod 4 and a limiting plate 5 are added to the bottom of the feeding platform 3. The output end of the first push rod 4 is equipped with the limiting plate 5. There are two sets of the first push rod 4 and the limiting plate 5.
