Description

Technical Field

[0001] This utility model relates to the field of hoist technology, specifically to a sealing adjustment device for the shell of a plate chain hoist. Background Technology

[0002] The hoist casing, especially the head casing, needs to be sealed because material conveying during operation generates dust. If the head casing is not sealed properly, dust will leak out through gaps, causing environmental pollution, endangering the health of operators, and even causing malfunctions. Therefore, sealing is crucial for ensuring stable equipment operation and protecting the environment and personnel safety.

[0003] Existing technologies for sealing the head shell of elevators mostly employ sealing strips. Specifically, sealing strips of fixed shape and size are installed at the connection between the head shell and related components. The elastic deformation of the sealing strip fills the gaps, thereby preventing material dust leakage and preventing external impurities from entering the equipment. However, this sealing method has significant limitations: it cannot flexibly adjust the sealing performance. In actual operation, due to changes in equipment operating conditions, such as temperature fluctuations, differences in material properties, and vibration, the size of the gaps at the shell connection can easily change. Existing sealing strip methods cannot adjust to these changes to enhance the sealing effect. Once the gap changes beyond the sealing strip's adaptability range, sealing problems easily occur, leading to a series of adverse consequences such as dust leakage and accelerated equipment wear. Therefore, we propose a plate chain elevator shell sealing performance adjustment device. Utility Model Content

[0004] One of the technical problems this application aims to solve is that the size of the gap at the housing connection can easily change due to changes in the operating conditions of the equipment, but the existing sealing strip sealing method cannot adjust and enhance the sealing effect according to these changes.

[0005] To address the aforementioned technical problems, this application provides a sealing adjustment device for a plate chain elevator housing, comprising a main housing and further including:

[0006] A head housing is disposed on top of the main housing. A plate is fixedly connected inside the head housing. A first sealing strip and a second sealing strip are provided between the main housing and the head housing for initial sealing.

[0007] An adjustment unit is disposed inside the head housing. The adjustment unit includes a toothed column, a toothed plate, and a sealing tube. The toothed column drives the toothed plate to rise and fall, thereby driving the sealing tube to compress, and thus adjusting the sealing effect of the first sealing strip and the second sealing strip.

[0008] In some embodiments, the adjustment unit includes a drive member disposed within the head housing for driving the gear column to rotate, and a driven member disposed within the head housing for driving the sealing tube to compress, thereby strengthening the seal.

[0009] In some embodiments, the drive includes a rotating shaft rotatably connected to the outside of the head housing, a rotating wheel fixedly connected to the outer end of the rotating shaft, a first gear fixedly connected to the inner end of the rotating shaft extending into the head housing, two support plates fixedly connected to the inner bottom of the head housing, a toothed column rotatably connected between the two support plates, a second gear fixedly sleeved at one end of the toothed column, the first gear and the second gear meshing, and bevel gears fixedly connected to both ends of the toothed column.

[0010] In some embodiments, the support plate, toothed column, and bevel gear are arranged in four groups, all of which are arranged around the central axis of the head housing, and the four groups of bevel gears mesh with each other.

[0011] In some embodiments, the driven member includes a limiting plate fixedly connected to the bottom of the head housing, a toothed plate slidably connected to one side of the limiting plate, the bottom end of the toothed plate penetrating the head housing, the toothed plate meshing with a toothed column, a push frame fixedly connected to the bottom end of the toothed plate, and a sealing tube fixedly connected to the bottom of the push frame.

[0012] In some embodiments, the number of limiting plates and toothed plates is set to four sets, the bottom ends of the four toothed plates are fixedly connected to the push frame, and the four sets of limiting plates and toothed plates are arranged around the central axis of the head housing.

[0013] In some embodiments, a first sealing strip is fixedly connected to the top of the main housing, and a second sealing strip is fixedly connected to the bottom of the head housing. The first and second sealing strips fit together to seal. Fixing blocks are fixedly connected to all four sides of the main housing and the head housing, and fixing rods are threaded into the four sets of fixing blocks.

[0014] This utility model has at least the following beneficial effects:

[0015] Initial sealing is achieved through the first and second sealing strips. Then, the driving component is driven to compress the sealing tube. After compression, the sealing tube will abut and seal the connection between the first and second sealing strips, enhancing the sealing effect between them. Similarly, the deformation and expansion of the sealing tube will abut and seal the gap between the push frame and the head housing, as well as the gap between the push frame and the plate. In short, the sealing between the head housing and the main housing can be adjusted. Attached Figure Description

[0022] 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. Example 1

[0023] Please see Figures 1-5 This utility model provides a technical solution:

[0024] A sealing adjustment device for a plate chain elevator casing includes a main casing 1, a head casing 2, and an adjustment unit 4. The head casing 2 is located on top of the main casing 1, and a plate 3 is fixedly connected inside the head casing 2. A first sealing strip 5 and a second sealing strip 6 are provided between the main casing 1 and the head casing 2 for initial sealing. The adjustment unit 4 is located inside the head casing 2 and includes a toothed column 415, a toothed plate 422, and a sealing tube 424. The toothed column 415 drives the toothed plate 422 to rise and fall, thereby driving the sealing tube 424 to compress, thus adjusting the sealing effect of the first sealing strip 5 and the second sealing strip 6. The plate 3 is fixedly connected inside the head casing 2, and its outer edge contacts the push frame 423. Through the deformation and expansion of the sealing tube 424, it can abut and seal the gap.

[0025] The adjustment unit 4 includes a drive component 41 disposed inside the head housing 2, used to drive the gear column 415 to rotate. The drive component 41 includes a rotating shaft 411 rotatably connected to the outside of the head housing 2. A rotating wheel 412 is fixedly connected to the outer end of the rotating shaft 411. The inner end of the rotating shaft 411 extends into the head housing 2 and is fixedly connected to a first gear 413. Two support plates 414 are fixedly connected to the inner bottom of the head housing 2. A gear column 415 is rotatably connected between the two support plates 414. A second gear 416 is fixedly sleeved at one end of the gear column 415. The first gear 413 and the second gear 416 mesh. Both ends of the gear column 415 are fixedly connected to bevel gears 417. The support plates 414, gear column 415 and bevel gears 417 are arranged in four groups. The four groups are arranged around the central axis of the head housing 2. The four groups of bevel gears 417 mesh with each other. The four groups of bevel gears 417 have the same specifications and can mesh smoothly.

[0026] A follower 42 is provided inside the head housing 2 to drive the sealing tube 424 to compress, thereby strengthening the seal. The follower 42 includes a limiting plate 421 fixedly connected to the bottom of the head housing 2. A toothed plate 422 is slidably connected to one side of the limiting plate 421. The bottom end of the toothed plate 422 penetrates the head housing 2 and meshes with a toothed column 415. A push frame 423 is fixedly connected to the bottom end of the toothed plate 422. The bottom of the push frame 423 is fixedly connected to the sealing tube 424, which is filled with gas to facilitate compression deformation and expansion. The number of limiting plates 421 and toothed plates 422 is set to four sets. The bottom ends of the four toothed plates 422 are all fixedly connected to the push frame 423. The four sets of limiting plates 421 and toothed plates 422 are arranged around the central axis of the head housing 2. The limiting plate 421 plays the role of supporting and limiting the toothed plates 422 to prevent the toothed plates 422 from breaking.

[0027] In use, firstly, the head housing 2 and the main housing 1 are joined together, and the first sealing strip 5 and the second sealing strip 6 are closed and sealed. Then, the rotating wheel 412 is rotated, which drives the rotating shaft 411 to rotate, which in turn drives the first gear 413 to rotate. The first gear 413 drives the second gear 416 to rotate, and the second gear 416 drives a toothed column 415 to rotate. The rotation of the toothed column 415 drives a bevel gear 417 to rotate, which in turn drives another bevel gear 417 meshing with it to rotate. Then, all four toothed columns 415 rotate synchronously in the same direction, and the four toothed columns 415 in turn drive the four geared columns to rotate synchronously. The four toothed plates 422 descend, and the four toothed plates 422 simultaneously drive the push frame 423 to descend. The push frame 423 then drives the sealing tube 424 to descend. When the sealing tube 424 contacts the top of the main housing 1, it will be squeezed and deformed. After the deformation expands, it will abut against the connection between the first sealing strip 5 and the second sealing strip 6. This can enhance the sealing effect between the first sealing strip 5 and the second sealing strip 6. Similarly, the deformation and expansion of the sealing tube 424 will abut against and seal the gap between the push frame 423 and the head housing 2, as well as the gap between the push frame 423 and the plate 3, to prevent leakage. Example 2

[0028] Please see Figures 1-3 This utility model provides a technical solution:

[0029] Unlike Embodiment 1, the top of the main housing 1 is fixedly connected to a first sealing strip 5, and the bottom of the head housing 2 is fixedly connected to a second sealing strip 6. The first sealing strip 5 and the second sealing strip 6 fit together to seal. Fixing blocks 7 are fixedly connected to the four sides of the main housing 1 and the head housing 2. Fixing rods 8 are threaded into the four sets of fixing blocks 7. The first sealing strip 5 and the second sealing strip 6 are both provided with grooves to facilitate snap-fit ​​sealing.

[0030] After the head housing 2 is combined with the main housing 1, the first sealing strip 5 and the second sealing strip 6 are combined and sealed. Then, the four sets of fixing blocks 7 are fixed by the fixing rod 8. In this way, the first sealing strip 5 and the second sealing strip 6 can be used for initial sealing.
