Description

Technical Field

[0001] This utility model relates to the field of gate valve adjustment technology, specifically to a gate valve adjustment device for the bottom of a warehouse. Background Art

[0002] Slide gate valves are widely used in metallurgy, mining, building materials, and grain industries. They mainly function as seals to cut off the flow of materials. The sealing effect of slide gate valves is crucial to the normal operation of the valve itself and even the entire equipment. Most existing slide gate valves are controlled by hydraulic cylinders, so they need to be inspected regularly. If the hydraulic cylinder is damaged, it needs to be disassembled and repaired, and in severe cases, it may even need to be replaced, resulting in high maintenance costs. Utility Model Content

[0003] In view of this, the present invention provides a bottom gate valve adjustment device that allows manual control of the valve plate height, thereby reducing subsequent maintenance costs.

[0004] To solve the above-mentioned technical problems, this utility model provides a bottom gate valve adjustment device, including a valve body. A discharge groove is opened on the lower side of one side of the valve body. An adjustment mechanism is provided inside the valve body. The adjustment mechanism includes a movable cavity opened inside the valve body and located above the discharge groove. A valve plate is slidably arranged in the movable cavity. A through groove adapted to the valve plate is opened on the lower wall of the movable cavity. The lower part of the valve plate passes through the through groove in the lower part of the movable cavity and extends into the discharge groove. The adjustment mechanism includes a sliding component for driving the valve plate to move up and down. When the operator installs the valve body at the discharge port of the processing equipment, when it is necessary to adjust the size of the discharge groove opening, the valve plate can be driven to slide up and down by the sliding component. By adjusting the height of the valve plate, the size of the discharge groove opening can be adjusted, thereby manually controlling the height of the valve plate and reducing subsequent maintenance costs.

[0005] The sliding assembly includes a connecting column mounted on the upper end of the valve plate. Lead screws are rotatably mounted on both sides inside the movable cavity. Threaded holes are opened at both ends of the connecting column, and the lead screws are threaded into these holes. The sliding assembly also includes a rotating component, which drives the two lead screws to rotate simultaneously. The operator rotates the two lead screws simultaneously using the rotating component. Since the two lead screws are threaded into the threaded holes on both sides of the connecting column, their rotation causes the connecting column to move upward or downward, thereby causing the connecting column to move the valve plate synchronously. This allows for free adjustment of the valve plate's height.

[0006] The rotating component includes a drive groove located above the interior of the movable cavity. The upper end of the lead screw penetrates the inner wall of the movable cavity and extends into the drive groove. A driven bevel gear is provided at the upper end of the lead screw. A rotating rod is rotatably mounted inside the drive groove. Two driving bevel gears are provided on both sides of the surface of the rotating rod, and each driving bevel gear is meshed with its corresponding driven bevel gear. The rotating component also includes a drive unit for driving the rotating rod to rotate. The operator drives the rotating rod to rotate via the drive unit. When the rotating rod rotates, it drives the driving bevel gears on the surface to rotate. When the driving bevel gears rotate, they drive the meshed driven bevel gears to rotate, thereby causing the driven bevel gears to drive the lead screw to rotate.

[0007] The drive unit includes a drive frame mounted on the upper side wall of the valve body. A driven gear is rotatably mounted on the upper part of the drive frame, and a drive gear is rotatably mounted on the lower part of the drive frame. The drive gear and the driven gear are meshed together. A hand crank is mounted on one outer side wall of the drive frame. The end of the hand crank passes through the side wall of the drive frame and is connected to the center of the end of the drive gear. A limit component is mounted on the outer side wall of the drive frame to limit and fix the driven gear. Before the operator turns the hand crank, the limit component is used to release the limit on the driven gear. Then, the operator turns the hand crank, which drives the drive gear to rotate. The drive gear drives the driven gear to rotate, which in turn drives the rotating rod to rotate. This, in turn, drives the two lead screws to rotate simultaneously. This allows the height of the valve plate to be manually adjusted. The size of the opening at the discharge chute can be adjusted without the need for hydraulic cylinders or other instruments, thereby reducing the maintenance cost of the valve body.

[0008] The cross-section of the drive gear is smaller than that of the driven gear. Since the small gear drives the large gear, it is easier for the operator to turn the hand crank.

[0009] The limiting component includes a limiting post rotatably mounted above one side wall of the drive frame. One end of the limiting post penetrates the side wall of the drive frame and is connected to the center of the driven gear. A limiting ring is fitted onto the surface of the limiting post, and several limiting grooves are evenly distributed on the inner wall of the limiting ring. A limiting block, corresponding to the position of the limiting groove, is provided on the surface of the limiting post and inserted into the limiting groove. A connecting plate is provided on the side wall of the drive frame, corresponding to the upper and lower sides of the limiting ring. A sliding groove is provided on the surface of the connecting plate, and sliders are provided on the upper and lower sides of the limiting ring. The sliders are slidably disposed within the sliding grooves of the connecting plate. When the operator... When the operator needs to remove the limiting fixation of the driven gear to drive the rotating rod to rotate, the limiting ring can be pulled to allow the slider to slide in the groove of the connecting plate, thereby disengaging the limiting block on the surface of the limiting post from the limiting groove, allowing the limiting post to rotate, thus removing the limiting fixation of the limiting post and the driven gear, allowing the limiting post to rotate with the driven gear. When it is necessary to limit the fixing of the driven gear, the limiting ring is pushed to allow the limiting block to re-engage in the limiting groove, thereby limiting the fixing of the limiting post, thus limiting the fixing of the driven gear and the rotating rod, and further limiting the fixing of the valve plate, fixing the valve plate at a specified height.

[0010] The limit ring has anti-slip ridges on both sides to prevent the operator's hand from slipping when moving the limit ring.

[0011] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0012] 1. When using this utility model, the operator installs the valve body at the discharge port of the processing equipment. When it is necessary to adjust the size of the discharge trough opening, the valve plate can be moved up and down by the sliding component. By adjusting the height of the valve plate, the size of the discharge trough opening can be adjusted, thereby manually controlling the height of the valve plate and reducing subsequent maintenance costs.

[0013] 2. When using this utility model, the operator drives the two lead screws to rotate simultaneously through the rotating component. Since the two lead screws are threaded into the threaded holes on both sides of the connecting column, the rotation of the two lead screws will drive the connecting column to move up or down, thereby causing the connecting column to drive the valve plate to move synchronously, and thus the height of the valve plate can be freely adjusted.

[0014] 3. When this utility model is in use, the operator drives the rotating rod to rotate through the driving component. When the rotating rod rotates, it drives the active bevel gear on the surface to rotate. When the active bevel gear rotates, it drives the meshing driven bevel gear to rotate, which in turn drives the lead screw to rotate.

[0015] 4. When using this utility model, before the operator turns the hand crank, the limiting component cancels the limit on the driven gear. Then, the hand crank is turned, which drives the drive gear to rotate. The drive gear drives the driven gear to rotate, which in turn drives the rotating rod to rotate. This causes the two lead screws to rotate simultaneously, thus allowing the height of the valve plate to be manually adjusted. The size of the opening at the discharge chute can be adjusted without the need for hydraulic cylinders or other instruments, thereby reducing the maintenance cost of the valve body.

DETAILED DESCRIPTION

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-6 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0024] According to one embodiment of the present invention, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown: This embodiment provides a bottom gate valve adjustment device, including a valve body 100. A discharge groove is provided on the lower side of one side of the valve body 100. An adjustment mechanism is provided inside the valve body 100. The adjustment mechanism includes a movable cavity 101 located inside the valve body 100 and above the discharge groove. A valve plate 200 is slidably disposed in the movable cavity 101. A through groove adapted to the valve plate 200 is provided on the lower wall of the movable cavity 101. The lower part of the valve plate 200 passes through the through groove in the lower part of the movable cavity 101 and extends into the discharge groove. The adjustment mechanism includes a sliding component for driving the valve plate 200 to move up and down. When the valve body 100 is installed at the discharge port of the processing equipment, the valve plate 200 can be slid up and down by the sliding component when it is necessary to adjust the size of the discharge groove opening. The size of the discharge groove opening can be adjusted by adjusting the height of the valve plate 200, thereby manually controlling the height of the valve plate 200 and reducing subsequent maintenance costs.

[0025] The sliding assembly includes a connecting column disposed on the upper end of the valve plate 200. Screws 400 are rotatably disposed on both sides inside the movable cavity 101. Threaded holes are opened at both ends of the connecting column, and the screws 400 are threadedly connected to the threaded holes of the connecting column. The sliding assembly also includes a rotating component, which drives the two screws 400 to rotate simultaneously. The operator drives the two screws 400 to rotate simultaneously via the rotating component. Since the two screws 400 are respectively threadedly connected to the threaded holes on both sides of the connecting column, the rotation of the two screws 400 will drive the connecting column to move upward or downward, thereby causing the connecting column to drive the valve plate 200 to move synchronously, thus allowing the height of the valve plate 200 to be freely adjusted.

[0026] The rotating component includes a drive groove 102 formed above the interior of the movable cavity 101. The upper end of the lead screw 400 penetrates the inner wall of the movable cavity 101 and extends into the drive groove 102. A driven bevel gear 401 is provided at the upper end of the lead screw 400. A rotating rod 402 is rotatably arranged in the drive groove 102. Two driving bevel gears 403 are provided on both sides of the surface of the rotating rod 402, and each driving bevel gear 403 is meshed with its corresponding driven bevel gear 401. The rotating component also includes a drive member for driving the rotating rod 402 to rotate. The operator drives the rotating rod 402 to rotate through the drive member. When the rotating rod 402 rotates, it drives the driving bevel gears 403 on the surface to rotate. When the driving bevel gears 403 rotate, they drive the meshed driven bevel gears 401 to rotate, thereby causing the driven bevel gears 401 to drive the lead screw 400 to rotate.

[0027] According to another embodiment of the present invention, such as Figure 4 , Figure 5 and Figure 6 As shown, the driving component includes a driving frame 500 disposed above one side wall of the valve body 100. A driven gear 501 is rotatably disposed on the upper part of the driving frame 500, and a driving gear 502 is rotatably disposed on the lower part of the driving frame 500. The driving gear 502 and the driven gear 501 are meshed together. A hand crank 503 is disposed on one outer side wall of the driving frame 500, with its end penetrating the side wall and connected to the center of the end of the driving gear 502. A limiting component is disposed on the outer side wall of the driving frame 500 for adjusting the position of the gear. The driven gear 501 is limited and fixed. Before the operator turns the hand crank 503, the limit component cancels the limit on the driven gear 501. Then, the operator turns the hand crank 503, which drives the drive gear 502 to rotate. The drive gear 502 drives the driven gear 501 to rotate, which in turn drives the rotating rod 402 to rotate. This drives the two lead screws 400 to rotate simultaneously, so that the height of the valve plate 200 can be manually adjusted. The size of the opening at the discharge chute can be adjusted without the need for hydraulic cylinders or other instruments, thereby reducing the maintenance cost of the valve body 100.

[0028] The cross-section of the drive gear 502 is smaller than that of the driven gear 501. Since the small gear drives the large gear to rotate, it is easier for the operator to turn the hand crank 503.

[0029] The limiting component includes a limiting post 600 rotatably mounted above one side wall of the drive frame 500. One end of the limiting post 600 penetrates the side wall of the drive frame 500 and is connected to the center of the end of the driven gear 501. A limiting ring 700 is fitted onto the surface of the limiting post 600. Several limiting grooves 701 are evenly formed on the inner wall of the limiting ring 700. A limiting block 601, which is adapted to the limiting groove 701, is provided on the surface of the limiting post 600 and is inserted into the limiting groove 701. A connecting plate 702 is provided on the side wall of the drive frame 500 and is positioned on the upper and lower sides of the limiting ring 700. A sliding groove is formed on the surface of the connecting plate 702. A slider 703 is provided on the upper and lower sides of the limiting ring 700 and is slidably disposed in the sliding groove of the connecting plate 702. When the operator needs to release the limiting fixation of the driven gear 501 to drive the rotating rod 402 to rotate, the limiting ring 700 can be pulled to make the slider 703 slide in the groove of the connecting plate 702, thereby causing the limiting block 601 on the surface of the limiting post 600 to disengage from the limiting groove 701, allowing the limiting post 600 to rotate, thus releasing the limiting fixation of the limiting post 600 and the driven gear 501, so that the limiting post 600 can rotate together with the driven gear 501. When it is necessary to limit the fixing of the driven gear 501, the limiting ring 700 is pushed to make the limiting block 601 re-engage in the limiting groove 701 to limit the fixing of the limiting post 600, thereby limiting the fixing of the driven gear 501 and the rotating rod 402, and then limiting the fixing of the valve plate 200, fixing the valve plate 200 at a specified height;

[0030] The limit ring 700 is provided with anti-slip protrusions 704 on both sides. The anti-slip protrusions 704 can prevent the operator's hand from slipping when moving the limit ring 700.

[0031] How to use this utility model:

[0032] The operator installs the valve body 100 at the discharge port of the processing equipment. When it is necessary to adjust the size of the discharge chute opening, the operator first pulls the limit ring 700, causing the limit block 601 on the surface of the limit post 600 to disengage from the limit groove 701, thereby releasing the limit on the driven gear 501 and the rotating rod 402. Then, the operator turns the hand crank 503, which drives the drive gear 502 to rotate. The drive gear 502 drives the driven gear 501 to rotate, causing the driven gear 501 to drive the rotating rod 402 to rotate. When the rotating rod 402 rotates, it drives the active bevel gear 403 on the surface to rotate. When the active bevel gear 403 rotates, it drives the meshing driven bevel gear 401 to rotate, which in turn drives the lead screw 400 to rotate. Since the two lead screws 400 are threadedly connected to the threaded holes on both sides of the connecting column, the two lead screws 400 will drive the connecting column to move up or down when they rotate, thereby causing the connecting column to drive the valve plate 200 to move synchronously, so as to manually adjust the height of the valve plate 200, thereby reducing the subsequent maintenance cost.

[0033] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
