Description

Technical Field

[0001] This application relates to the technical field of material conveying in the metallurgical industry, and in particular to a central furnace charging and lifting tower. Background Technology

[0002] In the metallurgical industry, the development of material conveying technology is of great significance for improving production efficiency and reducing costs. Currently, common material conveying technologies include belt conveyors, screw conveyors, and pneumatic conveying systems. Belt conveyors are widely used due to their simple and reliable structure, screw conveyors are suitable for short-distance conveying, and pneumatic conveying systems offer high transmission speeds and a high degree of automation.

[0003] However, existing material conveying methods all require operators to transfer materials from the feeding trolley to the conveyor or conveying system, which is inefficient. Summary of the Invention

[0004] To address the issue of existing feeding devices requiring material transfer to feed a central furnace, this application provides a central furnace feeding and lifting tower.

[0005] The technical solution for a central furnace charging tower provided in this application is as follows: A central furnace charging tower includes: The support frame is fixedly installed on the ground. The traction mechanism, fixedly connected to the support frame, is used to traction the trolley; The lifting platform is rotatably mounted on one side of the traction mechanism to restrict the position of the trolley, thereby connecting the traction mechanism and the trolley. A rotating mechanism, detachably connected to the traction mechanism and the lifting platform, is used to rotate the lifting platform to rotate the trolley, causing the material inside the trolley to leave the trolley.

[0006] By adopting the above technical solution, the support frame can provide a stable support point, the lifting platform can limit the position of the trolley, the traction mechanism can pull the lifting platform, thereby pulling the trolley generated by the lifting platform, and the rotating mechanism can rotate the lifting platform, thereby rotating the trolley, so that the material in the trolley leaves the trolley, completing the feeding of the central furnace. During the feeding process, there is no need for operators to transfer the material from the feeding trolley to the conveyor or conveying system, which improves the problem of existing feeding devices needing to transfer materials to feed the central furnace.

[0007] Preferably, the traction mechanism includes a first sprocket, a second sprocket, a chain, a reducer, and a motor. The first sprocket is rotatably disposed on the upper part of the support frame, and the second sprocket is rotatably disposed on the lower part of the support frame. The chain connects the first sprocket and the second sprocket to drive the first sprocket and the second sprocket. The reducer is fixedly connected to the second sprocket and is used to drive the second sprocket to rotate. The motor is driven by the reducer and is used to drive the reducer to rotate.

[0008] By adopting the above technical solution, the motor can provide power to the reducer to drive the first and second sprockets to rotate around the axis, thereby driving the chain to move. The chain pulls the platform, ultimately achieving the traction of the trolley.

[0009] Preferably, both the first sprocket and the second sprocket are double-row sprockets.

[0010] By adopting the above technical solution, the double-row sprocket can withstand a large torque, which can meet the needs of high-power mechanical equipment.

[0011] Preferably, the lifting platform includes a support plate, one side of which is rotatably connected to the chain, and the support plate has a receiving hole for accommodating the wheels of the trolley.

[0012] By adopting the above technical solution, the receiving hole allows the wheels of the trolley to be embedded in it. In this way, during the lifting and lowering of the trolley, the wheels will not interfere with other components of the lifting tower, nor will they rotate on the support plate, thus ensuring the stability and safety of the trolley during vertical movement.

[0013] Preferably, the lifting platform is further provided with a clamping mechanism, which includes a clamping plate, a transmission assembly, and an abutment plate. The clamping plate is disposed opposite to the receiving hole. The clamping plate is connected to the abutment plate through the transmission assembly. The transmission assembly is used to transmit the power of the abutment plate to the clamping plate to clamp the wheels of the trolley. The abutment plate is movably disposed at the bottom of the support plate.

[0014] By adopting the above technical solution, the clamping plate can restrict the position of the trolley's wheels when pulling the trolley, preventing the wheels from slipping out of the receiving hole and / or the wheels from rotating, thus improving the stability of the trolley during vertical movement and ensuring the safety of the material conveying process; the abutment plate can drive the clamping plate to release the wheels when the bearing plate abuts against the ground, and release the restriction on the clamping plate when the receiving platform leaves the ground, thereby allowing the clamping plate to clamp the wheels.

[0015] Preferably, the support plate has a cavity, which is located on the side of the support plate near the receiving hole, and the cavity is used to accommodate the clamping mechanism.

[0016] By adopting the above technical solution, the cavity allows the clamping mechanism to be built into the bearing plate, reducing the possibility of interference from external factors, while also protecting the components of the clamping mechanism and extending its service life.

[0017] Preferably, the transmission assembly includes a connecting rod, a movable plate, an elastic element, a first transmission element, and a second transmission element. The connecting rod is movably inserted into the cavity. The movable plate, the elastic element, and the first transmission element are all disposed in the cavity. One end of the connecting rod is detachably connected to the side of the clamping plate away from the receiving hole. The end of the connecting rod away from the clamping plate is detachably connected to the movable plate. The movable plate is slidably connected to the bearing plate. The side of the movable plate away from the connecting rod is fixedly connected to one end of the elastic element. The end of the elastic element away from the movable plate is fixedly connected to the bearing plate. The first transmission element is disposed on the side of the movable plate away from the elastic element and is fixedly connected to the movable plate and the bearing plate. The second transmission element is disposed between the bearing plate and the abutment plate and is fixedly connected to the bearing plate and the abutment plate. The first transmission element and the second transmission element are connected in a transmission manner.

[0018] By adopting the above technical solution, the elastic element can drive the movable plate to move when the bearing plate leaves the ground, thereby driving the clamping plate to move through the connecting rod, so that the clamping plate clamps the wheel; when the bearing plate comes into contact with the ground, the contact plate can drive the liquid of the second transmission element into the first transmission element, thereby pushing the movable plate, so that the elastic element is reset, and finally the clamping plate releases the wheel.

[0019] Preferably, the bottom of the bearing plate is further provided with a groove, the groove being disposed opposite to the second transmission member, and the groove matching the abutment plate.

[0020] By adopting the above technical solution, the groove can accommodate the second transmission component and the abutment plate, so that the abutment plate enters the groove when the bearing plate abuts against the ground, thus preventing the bearing plate from breaking.

[0021] Preferably, the lifting platform is further provided with a guide plate, which is fixedly disposed on one side of the bearing plate and is inclined.

[0022] By adopting the above technical solution, the guide plate can guide the material leaving the trolley and ensure that the material enters the central furnace.

[0023] Preferably, the rotating mechanism is a roller motor, the end of the rotating mechanism is detachably connected to the chain, and the wall of the rotating mechanism is detachably connected to the side of the guide plate away from the bearing plate.

[0024] By adopting the above technical solution, the drum motor can drive the support plate to move, thereby causing the trolley to tilt, and finally causing the material in the trolley to fall into the central furnace.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The support frame provides a stable support point, the lifting platform restricts the position of the trolley, the traction mechanism pulls the lifting platform to pull the trolley, and the rotating mechanism rotates the lifting platform to rotate the trolley, so that the material in the trolley leaves the trolley and completes the feeding of the central furnace. During the feeding process, there is no need for operators to transfer the material from the feeding trolley to the conveyor or conveying system, which improves the problem of existing feeding devices that require the transfer of materials to feed the central furnace. 2. The motor can provide power to the reducer to drive the first and second sprockets to rotate around the axis, thereby driving the chain to move. The chain pulls the platform, ultimately achieving the traction of the trolley. 3. Double-row sprockets can withstand greater torque, meeting the needs of high-power mechanical equipment.

[0028] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0029] This application discloses a central furnace charging and lifting tower. (Refer to...) Figure 1 and Figure 2 The central furnace charging tower includes a support frame 1, a traction mechanism 2, and a lifting platform 3.

[0030] like Figure 2 and Figure 3 As shown, the support frame 1 is built on the ground and is located on one side of the feed inlet of the central furnace. In this embodiment, the support frame 1 is built of several metal plates and metal rods to provide support points for the traction mechanism 2 and the lifting platform 3.

[0031] like Figure 3 and Figure 4 As shown, the traction mechanism 2 is fixedly connected to the support frame 1 and is used to traction the trolley. In this embodiment, the traction mechanism 2 includes a first sprocket 21, a second sprocket 22, a chain 23, a reducer 24, and a motor 25. The first sprocket 21 and the second sprocket 22 are respectively transmissively mounted on the upper and lower parts of the support frame 1 via hinges. There are two of each type of sprocket, with the two first sprockets 21 facing each other and the two second sprockets 22 facing each other. The chain 23 is sleeved on the corresponding first sprocket 21 and the corresponding second sprocket 22 to enable the corresponding first sprocket 21 and the corresponding second sprocket 22 to be transmissively connected. The reducer 24 is specifically a worm gear reducer 24, with both ends of the reducer 24 fixedly connected to the two second sprockets 22 to drive the second sprockets 22 to rotate. The motor 25 is transmissively connected to the reducer 24 and is used to drive the reducer 24 to rotate.

[0032] Specifically, the motor 25 can provide power to the reducer 24 to drive the first sprocket 21 and the second sprocket 22 to rotate around the axis, thereby driving the chain 23 to move. For example, in the embodiment of this application, the chain 23 is an iron chain, and there are four chains 23. The first sprocket 21 and the second sprocket 22 are both double-row sprockets. Double-row sprockets can withstand a large torque and can meet the high-load working requirements.

[0033] like Figure 4 As shown, the rotating mechanism 4 is a roller motor. The end of the rotating mechanism 4 is detachably connected to the corresponding chain 23 through a fixed seat or other structure. The wall of the rotating mechanism 4 is detachably connected to the lifting platform 3 through a fixed seat or other structure. Although the rotating mechanism 4 is small in size, the roller motor can provide a large torque, which is suitable for applications that require high torque.

[0034] Please refer to Figure 5 and Figure 6 The lifting platform 3 includes a support plate 31 and a clamping mechanism 33. A guide plate 36 for guiding material movement is fixedly installed on the side of the support plate 31 near the central furnace. The guide plate 36 is detachably connected to the wall of the rotating mechanism 4. The support plate 31 is connected to the chain 23 through the guide plate 36 and the rotating mechanism 4. The support plate 31 has a receiving hole 32 opposite to the wheel of the trolley. The receiving hole 32 allows the wheel of the trolley to be embedded in it. In this way, during the lifting and lowering of the trolley, the wheel will not interfere with other parts or rotate on the support plate 31, ensuring the stability and safety of the trolley when moving vertically. For example, there are two receiving holes 32, which are arranged side by side. Both receiving holes 32 extend to one side of the support plate 31 and are connected to the external environment. The wheel of the trolley can be pushed into the receiving hole 32 from one side of the support plate 31. Neither of the two receiving holes 32 is opposite to or away from the central furnace.

[0035] like Figure 6 and Figure 7 As shown, the clamping mechanism 33 includes a clamping plate 331, a transmission assembly 332, and an abutment plate 333. The clamping plate 331 is disposed opposite to the receiving hole 32. The clamping plate 331 is connected to the abutment plate 333 via the transmission assembly 332. The transmission assembly 332 is used to transmit the power of the abutment plate 333 to the clamping plate 331 to drive the clamping plate 331 to abut against the wheels of the trolley. The abutment plate 333 is movably disposed at the bottom of the support plate 31. The clamping plate 331 can restrict the position of the trolley wheels when the trolley is being pulled, preventing the wheels from slipping out of the receiving hole 32 and / or the wheels from rotating, thereby improving the stability of the trolley during vertical movement and ensuring the safety of the material conveying process. The abutment plate 333 can drive the clamping plate 331 to release the restriction on the wheels when the support plate 31 abuts against the ground, and release the restriction on the clamping plate 331 when the receiving platform leaves the ground, thereby allowing the clamping plate 331 to abut against the wheels.

[0036] It should be noted that, in this embodiment of the application, the support plate 31 has a cavity 34 for accommodating the clamping mechanism 33. The cavity 34 is located on the side of the support plate 31 near the receiving hole 32. The cavity 34 allows part of the structure of the clamping mechanism 33 to be built into the support plate 31, reducing the possibility of interference from external factors, while also protecting the components of the clamping mechanism 33 and extending its service life.

[0037] like Figure 7As shown, the transmission assembly 332 includes a connecting rod 3321, a movable plate 3322, an elastic element 3323, a first transmission element 3324, and a second transmission element 3325. The connecting rod 3321 passes through the bearing plate 31 and is movably inserted into the cavity 34. The movable plate 3322, the elastic element 3323, and the first transmission element 3324 are all disposed in the cavity 34. One end of the connecting rod 3321 is detachably connected to the side of the clamping plate 331 away from the receiving hole 32. The other end of the connecting rod 3321 away from the clamping plate 331 is detachably connected to the movable plate 3322. The movable plate 3322 is slidably connected to the bearing plate 31. The side of the movable plate 3322 away from the connecting rod 3321 is fixedly connected to one end of the elastic element 3323. The end of 3323 away from the movable plate 3322 is fixedly connected to the support plate 31. The first transmission member 3324 is disposed on the side of the movable plate 3322 away from the elastic member 3323. The first transmission member 3324 is fixedly connected to the movable plate 3322 and the support plate 31. The second transmission member 3325 is disposed between the support plate 31 and the abutment plate 333. The second transmission member 3325 is fixedly connected to the support plate 31 and the abutment plate 333. For example, the first transmission member 3324 and the second transmission member 3325 are both elastic bags. The first transmission member 3324 is connected to the second transmission member 3325 through a pipe that passes through the support plate 31. Both the first transmission member 3324 and the second transmission member 3325 are filled with liquid.

[0038] Specifically, the elastic element 3323 can drive the movable plate 3322 to move when the support plate 31 leaves the ground, thereby driving the clamping plate 331 to move through the connecting rod 3321. The clamping plate 331 abuts against the wheel, preventing the wheel from slipping out of the receiving hole 32 and / or the wheel from rotating. At this time, the bottom of the trolley abuts against the top of the support plate 31. When the lifting platform 3 abuts against the ground, the abutting plate 333 can drive the liquid of the second transmission element 3325 into the first transmission element 3324, thereby pushing the movable plate 3322, causing the elastic element 3323 to reset, and finally separating the clamping plate 331 from the wheel, releasing the restriction on the position of the trolley.

[0039] For example, a plurality of clamping mechanisms 33 are provided, and the plurality of clamping mechanisms 33 are arranged opposite each other and / or equally spaced.

[0040] like Figure 7 As shown, the bottom of the support plate 31 in this embodiment of the application is provided with a groove 35. The groove 35 is disposed opposite to the second transmission member 3325, and the groove 35 matches the abutment plate 333 and the second transmission member 3325, so that when the support plate 31 contacts the ground, the abutment plate 333 and the second transmission member 3325 are accommodated by the groove 35, thus preventing the lifting platform 3 from breaking.

[0041] The implementation principle of a central furnace feeding lifting tower according to an embodiment of this application is as follows: The operator pushes the trolley from one side of the lifting platform 3 towards the lifting platform 3 until the wheels of the trolley enter the receiving hole 32. The motor 25 drives the reducer 24 to rotate, thereby driving the first sprocket 21 and the second sprocket 22 to rotate, thereby driving the chain 23 to move, which in turn drives the lifting platform 3 to move, and finally pulls the trolley. When the lifting platform 3 separates from the ground, the clamping mechanism 33 restricts the position of the trolley. The rotating mechanism 4 rotates the trolley, causing the material in the trolley to fall into the central furnace. When the rotating mechanism 4 and the traction mechanism 2 reset, the lifting platform 3 contacts the ground. At this time, the clamping assembly releases the restriction on the wheels, allowing the operator to move the trolley out of the lifting platform 3.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
