Description

A type of calcium carbide furnace tapping cart Technical Field

[0001] This invention relates to the field of conveying facilities, and more particularly to a trolley for tapping out of a calcium carbide furnace. Background Technology

[0002] The calcium carbide furnace is the core equipment in calcium carbide production. It uses a high-temperature electric arc to react quicklime and coke to produce molten calcium carbide. It is a high-energy-consuming industrial electric furnace. During the operation of the calcium carbide furnace, a rail trolley is usually used as a conveyor to transport the calcium carbide pot for easy unloading.

[0003] During use, when the track trolley transports the calcium carbide pot, the pot is generally designed to be open. Therefore, if the transport is bumpy or the pot is overloaded, the molten calcium carbide inside is prone to splashing. The splashed molten calcium carbide is very hot and can easily cause serious burns to the personnel on site, resulting in a significant safety hazard during the transport process. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the prior art by proposing a trolley for tapping out calcium carbide furnaces.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a trolley for unloading a calcium carbide furnace, comprising a ground rail and a trolley mounted on the ground rail. A calcium carbide pot is placed on the upper end of the trolley. A positioning groove is formed on the upper surface of the trolley. The bottom of the calcium carbide pot is located inside the positioning groove. A cover is closed on the upper end of the calcium carbide pot. A cover frame is fixedly installed on the upper end of the cover. A cover seat is fixedly installed on the side of the trolley. A cover shaft is rotatably mounted through the end of the cover seat. The end of the cover frame is fixed to the outer surface of the cover shaft. A cover control gear is coaxially fixedly mounted on the end of the cover shaft. A cover control tooth plate meshes with the side of the cover control gear. The lower part of the cover control tooth plate is curved. A cover control wheel is installed on the end of the cover control tooth plate. A closing top rail and an opening top rail are installed at both ends of the ground rail. The opening top rail is located above the closing top rail. A cover fixing member is installed in the middle of the side of the cover seat.

[0006] Preferably, an ear seat extends from the upper side of the cover seat, a positioning ear is fixedly installed at the upper end of the ear seat, a limiting ear is fitted at the lower end of the positioning ear, and the end of the limiting ear is fixed to the cover frame.

[0007] Preferably, the cover includes a protruding frame extending to the middle of the side of the cover seat, a locking pin slidably mounted through the middle of the protruding frame, one end of the locking pin penetrating the side of the cover control plate, and the cover control plate slidably connected to the protruding frame.

[0008] Preferably, a column lug is fixedly installed at the other end of the locking cap column, a push column frame is rotatably installed at the end of the column lug, a top seat is rotatably installed at the end of the push column frame, the top seat is elastically connected to the extension frame, a release wheel is installed at the end of the top seat, a release top rail is installed at both ends of the ground rail, the release top rail is located above the opening top rail, a column hole is opened on the side of the control plate, and the locking cap column is inserted into the column hole.

[0009] Preferably, two guide ears extend symmetrically from one side of the extension frame, the control cover tooth plate is fitted between the two guide ears, and guide ridges extend from both the front and rear ends of the control cover tooth plate, with the guide ears slidably mounted on the outer surface of the guide ridges.

[0010] Preferably, two sliding lugs extend symmetrically from the other side of the extension frame, the top seat is slidably installed between the two sliding lugs, the lower end of the extension frame extends with a protrusion, the end of the protrusion is fixedly installed with a guide rod, the outer surface of the guide rod is slidably installed with a connecting frame, the end of the connecting frame is fixed to the top seat, a return spring is wound around the outside of the guide rod, one end of the return spring is fixed to the protrusion, and the other end of the return spring is fixed to the connecting frame.

[0011] Preferably, the upper and lower end faces of the top seat are provided with sliding grooves, the end of the sliding ear is slidably installed inside the sliding groove, the end of the guide rod is coaxially fixedly installed with a limit cap, and the connecting frame is pressed against the limit cap.

[0012] Preferably, a lower bracket is fixedly installed between the opposite sides of the closing top rail and the opening top rail, the end of the lower bracket is fixed to the ground rail, and an upper bracket is fixedly installed at the rear end of the lower bracket, the end of the upper bracket is fixed to the loosening top rail.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The cover can be placed over the calcium carbide pot to block the pot opening, thus trapping the molten calcium carbide inside. This prevents the molten calcium carbide from splashing during transport by the trolley, thereby improving safety during transport.

[0015] 2. When the trolley transports the calcium carbide pot to the receiving or unloading area, i.e., the two ends of the ground rail, the cover control wheel on the trolley will contact the lower end of the cover opening top rail. Under the push of the inclined surface at the end of the cover opening top rail, it will move downward, thereby driving the cover control tooth plate to move downward. The downward moving cover control tooth plate will drive the cover control gear to rotate, thereby driving the cover on the cover shaft to rotate, causing the cover to flip up and detach from the top of the calcium carbide pot, exposing the calcium carbide pot for receiving or unloading operations. After the receiving or unloading operation is completed, the trolley moves in the opposite direction. At this time, the inclined surface at the end of the cover closing top rail will push the cover control wheel upward, causing it to move upward and reset, thereby driving the cover control tooth plate to reset and re-cover the calcium carbide pot. In this way, the opening and closing operation of the cover can be completed synchronously during the trolley's transport process, without additional operation, which effectively facilitates use.

[0016] 3. After the cover is placed on the calcium carbide pot, the pin hole on the control plate aligns with the locking pin. Then, the return spring returns to its original shape, pushing the top seat backward. This, in turn, drives the locking pin to move laterally via the pusher frame, causing the locking pin to engage with the pin hole on the control plate. This fixes the control plate and locks the cover on the calcium carbide pot, ensuring that the cover always presses against the pot. Under the action of the cover, the calcium carbide pot is firmly pressed onto the trolley, ensuring that it will not tip over during transport and thus improving stability during transport.

[0026] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0027] As shown in Figures 1-8, a trolley for discharging from a calcium carbide furnace includes a ground rail 1 and a trolley 2 mounted on the ground rail 1. Since controlling the movement of the trolley 2 on the ground rail 1 for conveying operations is existing technology and widely used, it is not described in detail here. A calcium carbide pot 3 is placed on the upper end of the trolley 2. A positioning groove 5 is formed on the upper surface of the trolley 2. The bottom of the calcium carbide pot 3 is located inside the positioning groove 5. A cap 4 is placed on the upper end of the calcium carbide pot 3. The positioning groove 5 positions the calcium carbide pot 3, preventing it from shifting and ensuring that the cap 4 completely covers the calcium carbide pot 3. A cap frame 7 is fixedly installed on the upper end of the cap 4. The cover 4 is designed to cover the calcium carbide pot 3, thus blocking the opening of the pot and trapping the molten calcium carbide inside. This prevents splashing of the molten calcium carbide during transport by the trolley 2, improving safety. A cover seat 6 is fixedly installed on the side of the trolley 2, and a cover shaft 25 is rotatably mounted through the end of the cover seat 6. The cover seat 6 supports the cover shaft 25. The end of the cover frame 7 is fixed to the outer surface of the cover shaft 25, which ensures the cover 4 can rotate smoothly. A cover control gear 23 is coaxially fixed to the end of the cover shaft 25. The side of the cover 23 is engaged with a cover control gear 21. The cooperation between the cover control gear 23 and the cover control gear 21 controls the opening and closing of the cover 4. The lower part of the cover control gear 21 is curved, and a cover control wheel 20 is installed at the end of the cover control gear 21. Both ends of the ground rail 1 are equipped with a closing top rail 18 and an opening top rail 19. The opening top rail 19 is located above the closing top rail 18. A cover fixing component is installed in the middle of the side of the cover seat 6. When the trolley 2 drives the calcium carbide pot 3 to the receiving or unloading area, i.e., the end points of the ground rail 1, the cover control wheel 20 on the trolley 2 will contact the lower end of the opening top rail 19, so that it moves down under the push of the inclined surface at the end of the opening top rail 19, and then... The control cover tooth plate 21 is moved downward, which drives the control cover gear 23 to rotate, thereby driving the cover 4 on the cover shaft 25 to rotate and flip the cover 4 upward to detach it from the top of the calcium carbide pot 3, exposing the calcium carbide pot 3 for receiving or unloading. After the receiving or unloading operation is completed, the trolley 2 moves in the opposite direction. At this time, the inclined surface at the end of the cover top rail 18 will push the control cover wheel 20 upward, causing it to move upward and reset the control cover tooth plate 21, thereby driving the cover 4 to reset and re-cover the calcium carbide pot 3. In this way, the opening and closing operation of the cover 4 can be completed synchronously during the conveying process of the trolley 2, without additional operation, which effectively facilitates the use.

[0028] An ear seat 27 extends from the upper side of the cover 6. A positioning ear 26 is fixedly installed at the upper end of the ear seat 27. The ear seat 27 serves to support the positioning ear 26. A limiting ear 24 is fitted to the lower end of the positioning ear 26. The end of the limiting ear 24 is fixed to the cover frame 7. The cooperation between the positioning ear 26 and the limiting ear 24 can limit the cover 4, so that the cover 4 is flipped down to a horizontal state.

[0029] The fixing component includes a protruding bracket 17 extending from the middle of the side of the cover base 6. A locking pin 8 is slidably installed through the middle of the protruding bracket 17. The protruding bracket 17 serves to support the locking pin 8. One end of the locking pin 8 passes through the side of the control plate 21. The control plate 21 is slidably connected to the protruding bracket 17. The locking pin 8 can fix the control plate 21, thereby locking the cover 4 on the calcium carbide pot 3, so that the cover 4 always keeps pressing the calcium carbide pot 3, so that the calcium carbide pot 3 is firmly pressed onto the trolley 2 under the action of the cover 4.

[0030] A lug 9 is fixedly installed at the other end of the locking pin 8. A push pin bracket 10 is rotatably installed at the end of the lug 9, serving as a connection. A top seat 13 is rotatably installed at the end of the push pin bracket 10, and the top seat 13 is elastically connected to the extension bracket 17. A release wheel 14 is installed at the end of the top seat 13. Release top rails 12 are installed at both ends of the ground rail 1. The cooperation between the release wheel 14 and the release top rail 12 can drive the top seat 13 forward. The release top rail 12 is located at the top rail of the opening pin. Above 19, a pinhole 32 is provided on the side of the control cover tooth plate 21. The locking pin 8 is inserted into the pinhole 32. The pinhole 32 serves to cooperate with the locking pin 8. The release wheel 14 contacts the front end of the release top rail 12 and moves forward under the push of the end inclined surface of the release top rail 12, thereby driving the top seat 13 to move forward. The moving top seat 13 drives the locking pin 8 to move laterally through the push column frame 10, so as to pull the locking pin 8 out of the pinhole 32 on the control cover tooth plate 21.

[0031] Two guide ears 33 extend symmetrically from one side of the extension frame 17. The control cover tooth plate 21 is fitted between the two guide ears 33. Guide ribs 22 extend from both the front and rear ends of the control cover tooth plate 21. The guide ears 33 are slidably installed on the outer surface of the guide ribs 22. The cooperation between the guide ears 33 and the guide ribs 22 serves to guide the control cover tooth plate 21.

[0032] Two sliding lugs 16 extend symmetrically from the other side of the extension frame 17. The top seat 13 is slidably installed between the two sliding lugs 16, which guide the top seat 13. A lug 28 extends from the lower end of the extension frame 17, and a guide rod 31 is fixedly installed at the end of the lug 28, which supports the guide rod 31. A connecting frame 11 is slidably installed on the outer surface of the guide rod 31, and the end of the connecting frame 11 is fixed to the top seat 13. A return spring 29 is wound around the outside of the guide rod 31. The guide rod 31 guides the connecting frame 11 and prevents the return spring 29 from bending. One end of the positioning spring 29 is fixed to the lug 28, and the other end of the return spring 29 is fixed to the connecting frame 11. The return spring 29 restores its deformation to push the top seat 13 to move backward, and then drives the locking cover column 8 to move laterally through the push column frame 10, so that the locking cover column 8 is inserted into the column hole 32 on the control cover tooth plate 21 to fix the control cover tooth plate 21, and then lock the cover 4 on the calcium carbide pot 3, so that the cover 4 always keeps pressing the calcium carbide pot 3, so that the calcium carbide pot 3 is firmly pressed on the trolley 2 under the action of the cover 4, so as to ensure that the calcium carbide pot 3 will not tip over during the transportation process, thereby improving the stability during transportation.

[0033] The top and bottom surfaces of the top seat 13 are provided with sliding grooves 15. The end of the sliding ear 16 is slidably installed inside the sliding groove 15. The sliding groove 15 serves to allow the sliding ear 16 to slide. The end of the guide rod 31 is coaxially fixedly installed with a limit cap 30. The connecting frame 11 is pressed against the limit cap 30. The limit cap 30 serves to limit the reset position of the connecting frame 11.

[0034] A lower bracket 34 is fixedly installed between the opposite sides of the top rail 18 for closing and the top rail 19 for opening. The end of the lower bracket 34 is fixed to the ground rail 1. The lower bracket 34 serves to fix the top rail 18 for closing and the top rail 19 for opening. An upper bracket 35 is fixedly installed at the rear end of the lower bracket 34. The end of the upper bracket 35 is fixed to the top rail 12 for loosening. The upper bracket 35 serves to fix the top rail 12 for loosening.

[0035] During transport, the trolley 2 moves the calcium carbide pot 3 towards one end of the ground rail 1, transporting the calcium carbide pot 3 towards the receiving area. When it reaches the receiving area, the release wheel 14 first contacts the front end of the release top rail 12, and moves forward under the push of the inclined surface at the end of the release top rail 12, thereby driving the top seat 13 forward. The forward-moving top seat 13 passes through the push column frame 10 and drives the locking cover column 8 to move sideways, so that the locking cover column 8 is pulled out from the column hole 32 on the control cover tooth plate 21. At this time, the return spring 29 deforms. Then the trolley 2 continues to move. At this time, the control cover wheel 20 contacts the lower end of the opening top rail 19, so that the opening top rail 19 is inclined at the end of the release top rail 19. The surface moves downwards, causing the control cover tooth plate 21 to move downwards as well. The downward movement of the control cover tooth plate 21 drives the control cover gear 23 to rotate, thereby causing the cover 4 on the cover shaft 25 to rotate and flip upwards, detaching it from the top of the calcium carbide pot 3, exposing the calcium carbide pot 3. Then, the calcium carbide furnace can be turned on, allowing molten calcium carbide to flow into the calcium carbide pot 3. Subsequently, the trolley 2 moves in the opposite direction, moving the calcium carbide pot 3 towards the other end of the ground rail 1, thus transporting the calcium carbide pot 3 towards the unloading area. During this process, when the trolley 2 first begins to move in the opposite direction, the inclined surface at the end of the cover top rail 18 pushes the control cover wheel 20 upwards. This causes the control cover tooth plate 21 to move upward and reset, thereby driving the cover 4 to reset and re-cover the calcium carbide pot 3. After the cover 4 is closed on the calcium carbide pot 3, the post hole 32 on the control cover tooth plate 21 is aligned with the locking post 8. Then, the return spring 29 returns to its deformation, pushing the top seat 13 backward. This, in turn, drives the locking post 8 to move laterally through the push post bracket 10, so that the locking post 8 is inserted into the post hole 32 on the control cover tooth plate 21, thus fixing the control cover tooth plate 21 and locking the cover 4 closed on the calcium carbide pot 3. This ensures that the cover 4 always presses against the calcium carbide pot 3, so that the calcium carbide pot 3 is closed under the action of the cover 4. The lid is firmly pressed onto the trolley 2 to ensure that the calcium carbide pot 3 will not tip over during the conveying process. At the same time, the lid 4 covering the calcium carbide pot 3 will also block the opening of the pot, so that the molten calcium carbide is intercepted inside the pot 3. This prevents the molten calcium carbide inside the pot 3 from splashing during the conveying process when the trolley 2 moves the pot 3. When the pot 3 is conveyed to the unloading area, the release wheel 14 and the cover control wheel 20 will contact the release top rail 12 and the cover opening top rail 19 at the other end of the ground rail 1, causing the lid 4 to flip up and detach from the top of the calcium carbide pot 3, exposing the pot 3 for unloading.
