The first sprocket 21 and the second sprocket 22 are respectively drivably arranged at the upper and lower parts of the tower 1 through hinged ears. Two first sprockets 21 and two second sprockets 22 are each provided with two, the two first sprockets 21 are arranged opposite to each other, and the two second sprockets 22 are arranged opposite to each other. The chain 23 is sleeved on the corresponding first sprocket 21 and the corresponding second sprocket 22 so that the corresponding first sprocket 21 and the corresponding second sprocket 22 are transmission-connected. The reducer 24 is specifically a worm reducer 24, and the two ends of the reducer 24 are respectively fixedly connected to the two second sprockets 22 to drive the second sprockets 22 to rotate. The motor 25 is transmission-connected to the reducer 24, and the motor 25 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; exemplarily, in the embodiment of the present application, the chain 23 is an iron chain, and the chain 23 is provided with four chains. The first sprocket 21 and the second sprocket 22 are both double-row sprockets, and the double-row sprockets can withstand a larger torque and can meet high-load work requirements.

[0033] like Figure 4 As shown, the rotating mechanism 4 is a drum motor, and the end of the rotating mechanism 4 is detachably connected to the corresponding chain 23 through a fixed seat and other structures, and the wall of the rotating mechanism 4 is detachably connected to the supporting platform 3 through a fixed seat and other structures. Although the rotating mechanism 4 is small in size, the drum motor can provide a large torque and is suitable for occasions requiring high torque applications.

[0034] Please refer to Figure 5 and Figure 6The carrying platform 3 includes a carrying plate 31 and a clamping mechanism 33. A guide plate 36 for guiding the movement of materials is fixedly arranged on one side of the carrying plate 31 close to the central melting furnace. The guide plate 36 is detachably connected to the wall of the rotating mechanism 4. The carrying plate 31 is connected to the chain 23 through the guide plate 36 and the rotating mechanism 4; a receiving hole 32 opposite to the wheel of the cart is opened on the carrying plate 31, and the receiving hole 32 allows the wheel of the cart to be embedded therein, so that during the lifting process of the cart, the wheel will not interfere with other components, nor will it rotate on the carrying plate 31, thereby ensuring the stability and safety of the cart during vertical movement; illustratively, two receiving holes 32 are provided, and the two receiving holes 32 are arranged in parallel.

The wheel of the cart can be pushed into the receiving hole 32 from one side of the carrying plate 31, and the two receiving holes 32 are not opposite to or back to the central melting 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 arranged opposite to the accommodating hole 32. The clamping plate 331 is transmission-connected to the abutment plate 333 through 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 wheel of the cart. The abutment plate 333 is movably arranged at the bottom of the supporting plate 31. The clamping plate 331 can limit the position of the wheel of the cart when towing the cart, thereby preventing the wheel from slipping out of the accommodating hole 32 and / or the wheel from rotating, thereby improving the stability of the cart 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 wheel when the supporting plate 31 abuts against the ground, and release the restriction on the clamping plate 331 when the receiving platform leaves the ground, so that the clamping plate 331 abuts against the wheel.

[0036] It should be noted that, in the embodiment of the present application, the supporting plate 31 is provided with a cavity 34 for accommodating the clamping mechanism 33, and the cavity 34 is arranged on the side of the supporting plate 31 close to the accommodating hole 32; the cavity 34 allows part of the structure of the clamping mechanism 33 to be built into the supporting plate 31, reducing the possibility of interference therewith by 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 member 3323, a first bag 3324 and a second bag 3325. The connecting rod 3321 passes through the supporting plate 31 and is movably inserted in the cavity 34. The movable plate 3322, the elastic member 3323 and the first bag 3324 are all arranged in the cavity 34. One end of the connecting rod 3321 is detachably connected to a side of the clamping plate 331 away from the accommodating hole 32. The 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 supporting plate 31. The movable plate 3322 is slidably connected to the supporting plate 31. A side of 22 away from the connecting rod 3321 is fixedly connected to one end of the elastic member 3323, and one end of the elastic member 3323 away from the movable plate 3322 is fixedly connected to the supporting plate 31. The first bag 3324 is arranged on a side of the movable plate 3322 away from the elastic member 3323, and the first bag 3324 is fixedly connected to the movable plate 3322 and the supporting plate 31. The second bag 3325 is arranged between the supporting plate 31 and the abutment plate 333, and the second bag 3325 is fixedly connected to the supporting plate 31 and the abutment plate 333. The first bag 3324 is connected to the second bag 3325 via a pipe running through the supporting plate 31.

[0038] Specifically, the elastic member 3323 can drive the movable plate 3322 to move when the supporting plate 31 leaves the ground, thereby driving the clamping plate 331 to move through the connecting rod 3321, and the clamping plate 331 abuts against the wheel to prevent the wheel from slipping out of the accommodating hole 32 and / or the wheel from rotating. At this time, the bottom of the cart abuts against the top of the supporting plate 31; when the supporting platform 3 abuts against the ground, the abutment plate 333 can drive the liquid in the second bag 3325 to enter the first bag 3324, thereby pushing the movable plate 3322, resetting the elastic member 3323, and finally separating the clamping plate 331 from the wheel, thereby releasing the restriction on the position of the cart.

[0039] Exemplarily, a plurality of clamping mechanisms 33 are provided, and the plurality of clamping mechanisms 33 are opposite to each other in pairs and / or are distributed at equal intervals.

[0040] like Figure 7 As shown, a groove 35 is provided at the bottom of the supporting plate 31 in the embodiment of the present application, and the groove 35 is arranged opposite to the second bag 3325, and the groove 35 matches the abutment plate 333 and the second bag 3325, so that when the supporting plate 31 contacts the ground, the abutment plate 333 and the second bag 3325 are accommodated by the groove 35 to prevent the supporting platform 3 from breaking.

[0041] The implementation principle of a central furnace loading and lifting tower in an embodiment of the present application is as follows: an operator pushes a trolley from one side of a carrying platform 3 toward the carrying platform 3 until the wheels of the trolley enter the accommodating hole 32, and drives the reducer 24 to move through the motor 25 to drive the first sprocket 21 and the second sprocket 22 to rotate, thereby driving the chain 23 to move, and then driving the carrying platform 3 to move, and finally pulling the trolley. When the carrying platform 3 is separated from the ground, the clamping mechanism 33 limits the position of the trolley, and the trolley is rotated by the rotating mechanism 4 to make the material in the trolley fall into the central furnace; when the rotating mechanism 4 and the lifting mechanism 2 are reset, the carrying platform 3 contacts the ground, and at this time, the clamping assembly releases the restriction on the wheels, so that the operator can move the trolley out of the carrying platform 3.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
