Description

Technical Field

[0001] This invention relates to the field of casting equipment technology, specifically to a casting equipment for a gearbox body. Background Technology

[0002] The tilting ladle, which is part of the gearbox casting equipment, is a core tooling in the gearbox housing casting production line. It is used to receive molten steel at high temperatures. The ladle is hoisted to the sand mold station by an overhead crane and slowly tilted by the matching reduction mechanism. The forged trunnions on both sides of the ladle are paired with self-aligning bearings to achieve overall support. The trunnion on one side is connected to the worm gear reducer, and the tilting angle of the ladle is locked by the self-locking structure of the worm gear.

[0003] The worm gear transmission structure of the gearbox has several drawbacks: operators need to rotate the wheel quickly, yet the ladle tilts very slowly; molten iron continuously flows out during casting, and slow angle adjustments cannot quickly stop the flow; during the ladle's return to its original position, the ladle's discharge port shifts synchronously, causing excess molten iron to drip onto the molding sand surface, resulting in wasted steel. To address these shortcomings, this invention proposes an improved solution. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a gearbox casting device, including a lifting frame, a gearbox fixedly connected to the side wall of the lifting frame, a wheel rotatably connected to the side wall of the gearbox, a fixing frame fixedly connected to the output end of the wheel away from the gearbox, and a steel ladle fixedly connected to the inner wall of the fixing frame, and further comprising:

[0005] The positioning mechanism is slidably disposed on the inner wall of the ladle. The positioning mechanism includes a slide rod slidably connected to the inner wall of the ladle, a baffle plate fixedly connected to the top of the slide rod, an obstruction plate fixedly connected to the end of the baffle plate away from the slide rod, and a slide rail fixedly connected to the top of the slide rod.

[0006] The pushing mechanism is fixedly installed on the top of the ladle. The pushing mechanism includes a track fixedly connected to the top of the ladle, a sliding plate 1 slidably connected to the top of the track, and a sliding plate 2 slidably connected to the side wall of the sliding plate 1.

[0007] An auxiliary mechanism is rotatably disposed on the inner wall of a sliding plate. The auxiliary mechanism includes a rotating rod hinged to the inner wall of the sliding plate.

[0008] Workers can control the tilt angle of the ladle by rotating a wheel to carry out the pouring process.

[0009] Preferably, the positioning mechanism further includes:

[0010] A reset assembly is fixedly mounted at the bottom of the slide bar.

[0011] Limiting components are located at the bottom of the slide rail;

[0012] When the pushing mechanism and the auxiliary mechanism push the slide rail upward, the slide rod will slide upward along the inner wall of the ladle.

[0013] Preferably, the driving mechanism also includes:

[0014] The resistance component is fixedly installed at the bottom of the sliding plate one;

[0015] The auxiliary component is rotatably mounted on the inner wall of the sliding plate two.

[0016] The sliding plate can slide along the outer wall of the track.

[0017] Preferably, the auxiliary mechanism also includes:

[0018] A rotating assembly is rotatably connected to the end of a rotating rod that is away from a sliding plate.

[0019] The tensioning assembly is fixedly installed on the inner wall of the lifting frame;

[0020] Among them, the pulling component will drive the auxiliary component to slide along the inner wall of the sliding plate one.

[0021] Preferably, the reset assembly includes a spring fixedly connected to the bottom of the slide bar;

[0022] In normal conditions, the spring remains stretched and continuously pulls the slide bar downwards to reset.

[0023] Preferably, the limiting component includes a groove formed at the bottom of the slide rail;

[0024] Under normal conditions, the rotating component will be locked onto the inner wall of the slide.

[0025] Preferably, the resistance component includes a slider fixedly connected to a sliding plate;

[0026] There is sliding resistance between the sliding plate and the track, and the sliding resistance is greater than the pulling force of the spring.

[0027] Preferably, the auxiliary component includes a limiting post rotatably connected to the inner wall of the sliding plate two;

[0028] When the limiting post drives the sliding plate two to move, the sliding resistance between the slider and the sliding plate two is relatively large; the limiting post slides first and pushes the rotating rod one to flip upward around the hinge point; after the rotating rod one flips to the limit angle, the pulling force of the pulling component can drive the slider to slide along the track.

[0029] Preferably, the rotating assembly includes a roller rotatably connected to one end of the rotating rod away from the sliding plate;

[0030] The slide rail is restricted by the pull of the spring and will continue to slide downwards, so that the slide groove completely covers the outer wall of the roller.

[0031] Preferably, the pulling assembly includes a fixed rod fixedly connected to the inner wall of the lifting frame, and a rotating rod rotatably connected to the outer wall of the fixed rod;

[0032] Among them, the end of the rotating rod away from the fixed rod is rotatably connected to the outer wall of the limiting column. When the ladle is tilted, the rotating rod will cause the limiting column to slide.

[0033] The present invention has the following beneficial effects:

[0034] (1) This invention addresses the problem of slow ladle rotation speed leading to some molten iron spillage. It incorporates a pushing mechanism and an auxiliary mechanism inside the equipment. After pouring, the operator rotates the wheel to drive the ladle clockwise back to its original position; the distance between the fixed rod and the limiting post decreases, and the limiting post slides in the opposite direction; as the contact point between the rotating rod and the limiting post changes, the rotation angle of the rotating rod decreases; the spring pulls the sliding rod downwards, and the baffle plate descends synchronously to block the ladle outlet. This structure allows for rapid closure of the outlet when the ladle is reset, significantly reducing molten steel spillage and loss.

[0035] (2) The present invention utilizes the above-mentioned design of sliding plate 1 sliding along the outer wall of the track. A slider is provided inside the equipment. There is a large sliding resistance between the slider and sliding plate 2. When the rotating rod 2 generates a pulling force, the limiting post will slide first and force the rotating rod 1 to tilt upward with the hinge point as the center. When the rotating rod 1 tilts to the maximum angle, the obstruction plate no longer covers the outlet position of the ladle. However, as the total amount of molten iron inside the ladle decreases, the tilt angle of the ladle increases. At this time, the rotating rod 2 will pull the sliding plate 1 to slide to the right along the inner wall of the track. Through the above design, the equipment can autonomously adapt to the change in the total amount of molten iron.

[0036] (3) The present invention utilizes the above-mentioned design of the obstruction plate to intercept the ladle outlet position. A baffle plate is set inside the equipment, and a cavity is opened at the bottom of the baffle plate. When the obstruction plate completely covers the ladle outlet position, the baffle plate is tightly attached to the outer wall of the ladle under the pull of the spring. At this time, the baffle plate, the obstruction plate and the inner wall of the ladle outlet will form a storage space. Excess molten iron will be temporarily accumulated inside the storage space. Through the above design, the molten steel overflowing during the casting interception can be temporarily stored in the cavity, avoiding the sudden interception of molten steel splashing and leaking out everywhere.

[0037] (4) The present invention utilizes the characteristic that the above-mentioned baffle is always at the outlet position of the ladle. When the baffle does not block, the baffle is suspended above the outlet position. Due to its proximity to the high temperature of the molten iron, the molten iron is affected by the high temperature and always remains in a molten state and adheres to the inner wall of the baffle. When the baffle blocks, the molten iron enters the storage space and comes into contact with the molten iron, and drives the excess molten iron to flow back into the ladle. Through the above design, the residual iron slag impurities in the baffle cavity are reduced. Attached Figure Description

Detailed Implementation

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] Example 1, please refer to Figures 1-6 This invention relates to a gearbox casting device, comprising a lifting frame 13, a gearbox 14 fixedly connected to the side wall of the lifting frame 13, a rotating wheel 15 rotatably connected to the side wall of the gearbox 14, a fixing frame 16 fixedly connected to the output end of the rotating wheel 15 away from the gearbox 14, and a steel ladle 17 fixedly connected to the inner wall of the fixing frame 16, and further comprising:

[0051] Positioning mechanism 1 is slidably disposed on the inner wall of ladle 17. Positioning mechanism 1 includes a slide rod 111 slidably connected to the inner wall of ladle 17. A baffle plate 112 is fixedly connected to the top of slide rod 111. A blocking plate 114 is fixedly connected to the end of baffle plate 112 away from slide rod 111. A slide rail 121 is fixedly connected to the top of slide rod 111.

[0052] Pushing mechanism 2 is fixedly installed on the top of ladle 17. Pushing mechanism 2 includes a track 211 fixedly connected to the top of ladle 17. A sliding plate 213 is slidably connected to the top of track 211, and a sliding plate 221 is slidably connected to the side wall of sliding plate 213.

[0053] Auxiliary mechanism 3 is rotatably disposed on the inner wall of sliding plate 213. Auxiliary mechanism 3 includes a rotating rod 311 hinged to the inner wall of sliding plate 213.

[0054] Before use, the lifting frame 13 is assembled and fixed to the crane hoist; after adding sufficient molten steel into the ladle 17, the crane hoists the entire set of equipment to the pouring position; the operator rotates the rotating wheel 15 to adjust the tilt angle of the ladle 17, and the molten steel flows out along the guide channel of the ladle 17 to complete the pouring.

[0055] Positioning mechanism 1 also includes:

[0056] Reset assembly 11 is fixedly disposed at the bottom of slide bar 111;

[0057] Limiting component 12 is located at the bottom of slide rail 121;

[0058] When the pushing mechanism 2 and the auxiliary mechanism 3 push the slide rail 121 upward, the slide rod 111 will slide upward along the inner wall of the ladle 17.

[0059] The driving mechanism 2 also includes:

[0060] Resistance component 21 is fixedly installed at the bottom of sliding plate 213;

[0061] Auxiliary component 22 is rotatably disposed on the inner wall of sliding plate 221;

[0062] Among them, the sliding plate 213 can slide along the outer wall of the track 211.

[0063] Auxiliary mechanism 3 also includes:

[0064] Rotating assembly 31 is rotatably connected to the end of rotating rod 311 away from sliding plate 213;

[0065] The tensioning component 32 is fixedly installed on the inner wall of the lifting frame 13;

[0066] Among them, the pulling component 32 will drive the auxiliary component 22 to slide along the inner wall of the sliding plate 213.

[0067] Example 2, please refer to Figures 3-8 The present invention is a gearbox casting device. Based on the first embodiment, the reset component 11 includes a spring 113 fixedly connected to the bottom of the slide bar 111.

[0068] By utilizing the aforementioned design of the obstruction plate 114 to intercept the outlet position of the ladle 17, a baffle plate 112 is installed inside the equipment, and a chamber is opened at the bottom of the baffle plate 112. When the obstruction plate 114 completely covers the outlet position of the ladle 17, the baffle plate 112 is tightly attached to the outer wall of the ladle 17 under the pull of the spring 113. At this time, the baffle plate 112, the obstruction plate 114, and the inner wall of the outlet of the ladle 17 will form a storage space, and the excess molten iron will be temporarily accumulated inside the storage space. Through the above design, the molten steel overflowing during the casting interception can be temporarily stored in the cavity, preventing the molten steel from suddenly intercepting and splashing out everywhere.

[0069] The limiting component 12 includes a groove 122 formed at the bottom of the slide rail 121;

[0070] Taking advantage of the fact that the baffle plate 112 is always located at the outlet of the ladle 17, when the obstruction plate 114 does not block it, the baffle plate 112 is suspended above the outlet position. Due to its proximity to the high-temperature molten iron, the molten iron is affected by the high temperature and always remains in a molten state, adhering to the inner wall of the baffle plate 112. When the obstruction plate 114 blocks it, the molten iron enters the storage space, and the molten iron will come into contact with the molten iron, and carry the excess molten iron back into the ladle 17. Through the above design, the residual iron slag impurities in the cavity of the baffle plate 112 are reduced.

[0071] Resistance component 21 includes a slider 212 fixedly connected to the sliding plate 213;

[0072] There is sliding resistance between the sliding plate 213 and the track 211, and the sliding resistance is greater than the pulling force of the spring 113.

[0073] Auxiliary component 22 includes a limiting post 222 that is rotatably connected to the inner wall of sliding plate 221;

[0074] To address the issue of molten iron spilling due to the slow rotation speed of ladle 17, a pushing mechanism 2 and an auxiliary mechanism 3 are installed inside the equipment. For example... Figure 1 As shown, when the ladle 17 rotates counterclockwise, the distance between the fixing rod 321 and the limiting post 222 increases. Under the constraint of the rotating rod 322, the limiting post 222 will move towards the lifting frame 13, as shown. Figure 6 As shown, when the limiting post 222 moves to the right, the outer wall of the limiting post 222 will contact the bottom of the rotating rod 311. Under the limitation of the sliding resistance between the slider 212 and the track 211, the limiting post 222 will preferentially force the rotating rod 311 to produce an upward tilting tendency. The upward pushing of the rotating rod 311 will force the slide rail 121 and the slide rod 111 to slide upward. The slide rod 111 will drive the baffle plate 112 to slide upward, so that the obstruction plate 114 will no longer block the outlet position of the ladle 17.

[0075] Rotating assembly 31 includes a roller 312 rotatably connected to the end of rotating rod 311 away from sliding plate 213;

[0076] Utilizing the design of the sliding plate 213 sliding along the outer wall of the track 211, a slider 212 is installed inside the equipment. There is significant sliding resistance between the slider 212 and the sliding plate 221. When the rotating rod 322 generates a pulling force, the limiting post 222 will slide first, forcing the rotating rod 311 to tilt upwards around the hinge point. When the rotating rod 311 tilts to its maximum angle, it presents the following... Figure 6 As shown, at this time, the obstruction plate 114 no longer covers the outlet position of the ladle 17. However, as the total amount of molten iron inside the ladle 17 decreases, the tilt angle of the ladle 17 increases. At this time, the rotating rod 322 pulls the sliding plate 213 to slide to the right along the inner wall of the track 211. Through the above design, the equipment can autonomously adapt to the change in the total amount of molten iron.

[0077] The tensioning assembly 32 includes a fixed rod 321 fixedly connected to the inner wall of the lifting frame 13, and a rotating rod 322 rotatably connected to the outer wall of the fixed rod 321.

[0078] After pouring, the operator rotates the wheel 15 to drive the ladle 17 clockwise back to center; the distance between the fixed rod 321 and the limiting post 222 decreases, and the limiting post 222 slides in the opposite direction; as the contact point between the rotating rod 311 and the limiting post 222 changes, the rotation angle of the rotating rod 311 decreases; the spring 113 pulls the sliding rod 111 downward, and the baffle plate 114 descends simultaneously and blocks the outlet of the ladle 17. This structure can quickly close the outlet when the ladle is reset, greatly reducing the loss of molten steel spillage.

[0079] One specific application of this embodiment is as follows: Before use, the lifting frame 13 is first assembled and fixed to the crane hoist; after adding sufficient molten steel into the ladle 17, the crane hoists the entire set of equipment to the pouring position; the operator rotates the rotating wheel 15 to adjust the tilt angle of the ladle 17, and the molten steel flows out along the guide channel of the ladle 17 to complete the pouring;

[0080] To address the issue of molten iron spilling due to the slow rotation speed of ladle 17, a pushing mechanism 2 and an auxiliary mechanism 3 are installed inside the equipment. For example... Figure 1 As shown, when the ladle 17 rotates counterclockwise, the distance between the fixing rod 321 and the limiting post 222 increases. Under the constraint of the rotating rod 322, the limiting post 222 will move towards the lifting frame 13, as shown. Figure 6As shown, when the limiting post 222 moves to the right, the outer wall of the limiting post 222 will contact the bottom of the rotating rod 311. Under the limitation of the sliding resistance between the slider 212 and the track 211, the limiting post 222 will preferentially force the rotating rod 311 to have an upward tilting tendency. The upward pushing of the rotating rod 311 will force the slide rail 121 and the slide rod 111 to slide upward. The slide rod 111 will drive the baffle plate 112 to slide upward, so that the obstruction plate 114 will no longer block the outlet position of the ladle 17. After the pouring is completed, the operator rotates the rotating wheel 15 to drive the ladle 17 to return to the center clockwise. The distance between the fixed rod 321 and the limiting post 222 decreases, and the limiting post 222 slides in the opposite direction. As the contact point between the rotating rod 311 and the limiting post 222 changes, the rotation angle of the rotating rod 311 decreases. The spring 113 pulls the slide rod 111 down, and the baffle plate 114 descends synchronously and blocks the outlet of the ladle 17. This structure can quickly close the discharge port when the ladle is reset, greatly reducing the loss of molten steel spillage.

[0081] Utilizing the design of the sliding plate 213 sliding along the outer wall of the track 211, a slider 212 is installed inside the equipment. There is significant sliding resistance between the slider 212 and the sliding plate 221. When the rotating rod 322 generates a pulling force, the limiting post 222 will slide first, forcing the rotating rod 311 to tilt upwards around the hinge point. When the rotating rod 311 tilts to its maximum angle, it presents the following... Figure 6 As shown, at this time, the obstruction plate 114 no longer covers the outlet position of the ladle 17. However, as the total amount of molten iron inside the ladle 17 decreases, the tilt angle of the ladle 17 increases. At this time, the rotating rod 322 will pull the sliding plate 213 to slide to the right along the inner wall of the track 211. Through the above design, the equipment can autonomously adapt to the change in the total amount of molten iron.

[0082] By utilizing the aforementioned design of the obstruction plate 114 to intercept the outlet position of the ladle 17, a baffle plate 112 is installed inside the equipment, and a chamber is opened at the bottom of the baffle plate 112. When the obstruction plate 114 completely covers the outlet position of the ladle 17, the baffle plate 112 is tightly attached to the outer wall of the ladle 17 under the pull of the spring 113. At this time, the baffle plate 112, the obstruction plate 114, and the inner wall of the outlet of the ladle 17 will form a storage space, and the excess molten iron will be temporarily accumulated inside the storage space. Through the above design, the molten steel overflowing during the casting interception can be temporarily stored in the cavity, preventing the molten steel from suddenly intercepting and splashing out everywhere.

[0083] Taking advantage of the fact that the baffle plate 112 is always located at the outlet of the ladle 17, when the obstruction plate 114 does not block it, the baffle plate 112 is suspended above the outlet position. Due to its proximity to the high-temperature molten iron, the molten iron is affected by the high temperature and always remains in a molten state, adhering to the inner wall of the baffle plate 112. When the obstruction plate 114 blocks it, the molten iron enters the storage space, and the molten iron will come into contact with the molten iron, and carry the excess molten iron back into the ladle 17. Through the above design, the residual iron slag impurities in the cavity of the baffle plate 112 are reduced.
