Description
Technical Field
[0001] This utility model relates to the field of hoist technology, and in particular to a hoist sealing structure. Background Technology
[0002] In industrial production, elevators are core equipment for the vertical or inclined conveying of bulk materials such as ores, grains, and chemical raw materials, and are widely used in mining, grain storage, and building materials processing. With the increasing sophistication of production processes, the requirements for the sealing performance of elevators are becoming increasingly stringent. On the one hand, material leakage not only wastes raw materials and increases production costs but may also cause environmental pollution and safety hazards. On the other hand, the intrusion of external dust and impurities will accelerate the wear of internal components, reducing the elevator's operating efficiency and service life. Traditional elevators often use simple mechanical seals or rubber gasket seals, which are insufficient to meet the high standards of sealing and reliability required by modern industry under long-term high-load operation and complex working conditions.
[0003] Existing elevators typically consist of an elevator body, a drive unit, traction components, buckets, and sealing components. The elevator body serves as the main frame, providing support for the equipment's operation. The drive unit includes a motor and a reducer, which drives the traction components via a transmission belt or coupling. The traction components, such as chains or belts, connect to and drive the buckets for material conveying. The buckets are responsible for loading and lifting materials.
[0004] However, existing hoists generally suffer from poor sealing, failing to effectively prevent leakage of internally transported materials and the intrusion of external dust and impurities. Traditional bolt sealing components are prone to bolt loosening under long-term vibration, high temperature, or corrosive materials, leading to increased sealing gaps and material overflow from the joints. This results in material waste, pollution of the production environment, and serious impact on production continuity. Therefore, a hoist sealing structure is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a sealing structure for a hoist, which aims to improve the problem that traditional bolt sealing components in the prior art are prone to bolt loosening under the influence of long-term equipment vibration, and cannot effectively prevent leakage of internally conveyed materials.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A sealing structure for a hoist includes a hoist body, a conveyor belt disposed inside the hoist body, a partition plate fixedly connected to the outer wall of the conveyor belt, a connecting plate fixedly connected to the side wall of the hoist body, an mounting component disposed on one side of the connecting plate, a fixing rod fixedly connected inside the mounting component, a sealing component disposed on one side of the fixing rod, and a connecting component disposed inside the mounting component.
[0008] The sealing assembly includes a sealing baffle, one side of which is fixedly connected to one side of the fixing rod and fits against the hoist body. A sealing strip is fixedly connected to the other side of the sealing baffle. A sealing groove is provided inside the hoist body, and the sealing strip fits into the sealing groove.
[0009] As a further description of the above technical solution:
[0010] The connecting assembly includes a hollow column and a positioning pin. The outer wall of the hollow column is fixedly connected to the inside of the mounting component, and the positioning pin is slidably connected to the inside of the hollow column.
[0011] As a further description of the above technical solution:
[0012] The connecting plate has an installation hole inside, and the positioning pin is slidably connected inside the installation hole.
[0013] As a further description of the above technical solution:
[0014] The hollow column has a sliding column inside, and one end of the sliding column is fixedly connected to one end of the positioning pin.
[0015] As a further description of the above technical solution:
[0016] A spring is fitted on the outer wall of the sliding column, and the two ends of the spring are fixedly connected to the hollow column and the positioning pin, respectively.
[0017] As a further description of the above technical solution:
[0018] A transmission column is fixedly connected to the top of the sliding column, and a wrench is rotatably connected to the outer wall of the transmission column.
[0019] As a further description of the above technical solution:
[0020] A support column is fixedly connected inside the positioning pin, and a connecting column is slidably connected inside the support column. A retaining bead is fixedly connected to one end of the connecting column, and the retaining bead is slidably connected inside the positioning pin.
[0021] As a further description of the above technical solution:
[0022] A second spring is fitted on the outer wall of the connecting column, and the two ends of the second spring are respectively fixedly connected to the support column and the retaining ball.
[0023] This utility model has the following beneficial effects:
[0024] 1. In this utility model, the sealing baffle is fitted to the elevator body, and the sealing strip is embedded in the sealing groove to form an elastic sealing structure. At the same time, the positioning pin further enhances the connection stability. These structures work together to achieve an effective sealing effect when conveying materials. This solves the problem that traditional bolt sealing components are prone to bolt loosening under the influence of long-term equipment vibration, which cannot effectively prevent leakage of internally conveyed materials, thereby improving the sealing performance of the elevator.
[0025] 2. In this utility model, by rotating the wrench to drive the transmission column and sliding column to compress the spring, the positioning pin retracts and disengages from the mounting hole. At the same time, the connecting column drives the retaining ball to eliminate the clamping force. These structures work together to achieve the effect of quick disassembly and installation of the sealing baffle. This solves the problem of cumbersome disassembly of traditional sealing structures and the difficulty in timely replacement or maintenance of sealing components according to different material characteristics, thereby improving the flexibility of the hoist.

Detailed Implementation
[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0034] Reference Figures 1-3 An embodiment of this utility model provides a sealing structure for a hoist, including a hoist body 1, a conveyor belt 20 inside the hoist body 1, a partition 8 fixedly connected to the outer wall of the conveyor belt 20, a connecting plate 2 fixedly connected to the side wall of the hoist body 1, an installation component 3 on one side of the connecting plate 2, a fixing rod 4 fixedly connected inside the installation component 3, a sealing component on one side of the fixing rod 4, and a connecting component inside the installation component 3.
[0035] The sealing assembly includes a sealing baffle 5, one side of which is fixedly connected to one side of the fixing rod 4. The sealing baffle 5 is in close contact with the hoist body 1 to ensure the sealing performance of the hoist body 1. A sealing strip 7 is fixedly connected to the other side of the sealing baffle 5. The sealing strip 7 enhances the sealing effect. A sealing groove 6 is provided inside the hoist body 1. The sealing strip 7 fits into the sealing groove 6 to effectively prevent the intrusion of external air or debris, ensuring the sealing performance and operational stability of the hoist.
[0036] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5The connecting assembly includes a hollow column 10 and a positioning pin 14. The outer wall of the hollow column 10 is fixedly connected to the inside of the mounting component 3. The positioning pin 14 is slidably connected to the inside of the hollow column 10. The connecting plate 2 has a mounting hole 9 inside, and the positioning pin 14 is slidably connected to the inside of the mounting hole 9. A sliding column 11 is slidably connected inside the hollow column 10. One end of the sliding column 11 is fixedly connected to one end of the positioning pin 14. A spring 15 is sleeved on the outer wall of the sliding column 11. The two ends of the spring 15 are fixedly connected to the inside of the hollow column 10 and the positioning pin 14, respectively. A transmission column 12 is fixedly connected to the top of the sliding column 11. A wrench 13 is rotatably connected to the outer wall of the transmission column 12. A support column 16 is fixedly connected inside the positioning pin 14. A connecting column 17 is slidably connected inside the support column 16. One end of the connecting column 17 is fixedly connected to a retaining bead 18, which is slidably connected inside the positioning pin 14. A second spring 19 is sleeved on the outer wall of the connecting column 17. When the positioning pin 14 is inserted into the mounting hole 9, the retaining bead 18 can be pushed outward by the elastic force of the second spring 19 and tightly locked onto the outside of the mounting hole 9 to form a locking effect. The two ends of the second spring 19 are fixedly connected to the support column 16 and the retaining bead 18, respectively. When disassembling the sealing baffle 5, it is achieved by rotating the wrench 13. The wrench 13 drives the sliding column 11 to slide inside the hollow column 10 through the transmission column 12, compressing the first spring 15, causing the positioning pin 14 to retract into the hollow column 10, thereby disengaging from the mounting hole 9. This design makes the disassembly operation simple and efficient, reducing the difficulty and time of manual operation.
[0037] Working Principle: When using this elevator, it is necessary to prevent leakage of internally conveyed materials and the entry of external dust and impurities. The sealing baffle 5 is connected to the mounting component 3 via the fixing rod 4, and the sealing baffle 5 fits snugly against the elevator body 1. The sealing strip 7 on the other side of the sealing baffle 5 is fitted into the sealing groove 6 opened inside the elevator body 1. This fitting structure utilizes the elastic deformation of the sealing strip 7 to fill the gap between the sealing baffle 5 and the elevator body 1, forming a sealed space, effectively preventing material overflow and the intrusion of external pollutants, and ensuring the sealing and cleanliness of the internal conveying environment of the elevator.
[0038] When installing the sealing baffle 5, align the mounting part 3 with the connecting plate 2. At this time, the positioning pin 14, under the action of spring 15, is inserted into the mounting hole 9 inside the connecting plate 2. During the insertion process, the retaining ball 18, under the action of spring 2 19, tends to pop outward and will pop out and be stuck outside the mounting hole 9, further enhancing the stability of the connection between the positioning pin 14 and the mounting hole 9. Thus, the mounting part 3 and the sealing baffle 5 are firmly installed on the hoist body 1. When removing the sealing baffle 5, turn the wrench 13. The wrench 13 drives the transmission column 12 to... The sliding column 11 slides inside the hollow column 10, compressing the first spring 15, causing the positioning pin 14 to retract into the hollow column 10 and disengage from the mounting hole 9. At the same time, during the rotation of the wrench 13, the connecting column 17 overcomes the elastic force of the second spring 19, causing the retaining ball 18 to retract into the positioning pin 14, eliminating the clamping force of the retaining ball 18 on the mounting hole 9, making it easy for the positioning pin 14 to be pulled out of the mounting hole 9 smoothly. This allows the mounting part 3 and the sealing baffle 5 to be removed from the elevator body 1, facilitating the replacement or maintenance of the sealing baffle 5 according to the needs of lifting different materials.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
