[0032] In the related art, there is a loading platform made of concrete or steel structure above the transport vehicle. When adding metal raw materials into the iron ladle, the molten steel in the iron ladle will splash onto the loading platform, which can easily affect the mechanical properties of the loading platform and shorten its service life.

[0033] In the related art, there is a technical problem that the charging platform is easily affected by the splash of molten steel. The embodiment of the present application provides a ladle charging platform and system, which can at least solve the technical problem that the charging platform is easily affected by the splash of molten steel to a certain extent.

[0034] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, the ladle charging platform 100 includes a charging platform body 110 , a hopper 120 , a fixed roof mechanism 130 and a movable roof mechanism 140 .

[0036] The hopper 120 has a connected feed port 120a and a discharge port 120b, the feeding platform body 110 is provided with a first hopper avoidance hole 110a, one end of the hopper 120 provided with the discharge port 120b extends out of the feeding platform body 110 through the first hopper avoidance hole 110a, the feed port 120a is located on the upper side of the feeding platform body 110, and the discharge port 120b is located on the lower side of the feeding platform body 110; the hopper 120 is used to convey materials to the iron ladle 300 located therebelow.

[0037] It should be noted that the charging platform body 110 can be formed by pouring concrete, or can be formed by building steel materials such as I-beams, etc. The structure of the charging platform body 110 is diverse and is not limited in this application. The charging platform body 110 is located above the transport track 400 of the iron ladle transport vehicle 200. The operator can stand on the charging platform body 110 to feed materials into the hopper 120, or in some embodiments, a belt unloading system is provided above the charging platform body 110. The belt unloading system is used to transmit the materials added to the iron ladle 200, and the discharge port of the belt unloading system is located directly above the hopper 120 to feed materials into the hopper 120.

[0038] The hopper 120 is used to transfer materials. Specifically, it is used to transfer materials to the iron ladle 300 located therebelow. The materials entering from the feed port 120a are discharged from the discharge port 120b and can fall into the iron ladle 300.

[0039] The hopper 120 is mounted on the feeding platform body 110. The feeding platform body 110 is provided with a first hopper avoidance hole 110a. The first hopper avoidance hole 110a is a through hole. The hopper 120 is provided with one end of a discharge port 120b. Figure 1 The lower end of the first hopper 110 extends out of the charging platform body 110 through the first hopper avoidance hole 110a. In this way, the discharge port 120b is located at the lower side of the charging platform body 110, and the feed port 120a is located at the upper side of the charging platform body 110. The operator can stand on the charging platform body 110 and put the material into the feed port 120a. The material is discharged from the discharge port 120b under the diversion effect of the hopper 120 and finally falls into the iron ladle 300.

[0040] The functions of the fixed ceiling mechanism 130 and the movable ceiling mechanism 140 are to shield the molten metal and prevent the molten metal from splashing onto the feeding platform body 110 during the feeding process, thereby affecting the mechanical properties of the feeding platform body 110, thereby extending the service life of the platform body 110 and reducing the safety hazards of the workers such as those cleaning and inspecting equipment under the platform body 110.

[0041] Specifically, the fixed ceiling mechanism 130 is arranged below the feeding platform body 110 and is fixedly connected to the feeding platform body 110 for shielding the feeding platform body 110; the fixed ceiling mechanism 130 has a second hopper avoidance hole 130a, and one end of the hopper 120 is provided with a discharge port 120b extending out of the fixed ceiling mechanism 130 through the first hopper avoidance hole 110a.

[0042] The fixed roof mechanism 130 is fixedly connected to the feeding platform body 110 and is located below the feeding platform body 110. Under the action of the fixed roof mechanism 130, the fixed roof mechanism 130 shields the feeding platform body 110, and the splashing molten metal will be intercepted by the fixed roof mechanism 130, and the molten metal will not splash onto the feeding platform body 110.

[0043] The second hopper avoidance hole 130a is also a through hole. Figure 1 As shown, the lower end of the hopper 120 extends out of the fixed ceiling mechanism 130 through the second hopper avoidance hole 130a.

[0044] Specifically, the movable ceiling mechanism 140 includes a movable ceiling 141 and a driving assembly 142, the driving assembly 142 is connected to the movable ceiling 141 and the loading platform body 110; the movable ceiling 141 is located at the lower side of the fixed ceiling mechanism 130; a third hopper 120 avoidance hole is opened on the movable ceiling 141, and the third hopper 120 avoidance hole is used to avoid the hopper 120; under the action of the driving assembly 142 (142), the movable ceiling 141 can rise or fall.

[0045] After the material is added into the iron ladle 300 , the area of ​​the fixed ceiling mechanism 130 close to the iron ladle 300 is more susceptible to the splashing of the molten metal than the area far from the iron ladle 300 .

[0046] The movable ceiling 141 can rise or fall under the action of the driving component 142, and can achieve the following functions: the movable ceiling 141 can be lowered to the vicinity of the iron ladle 300 before the material is added to block most of the molten metal splashing out of the iron ladle 300; the movable ceiling 141 can also be in a high position all the time, and when there are many metal blocks adhered to the movable ceiling 141 (the molten metal splashes onto the movable ceiling 141, and metal blocks are formed after cooling and solidification), it will be lowered to a low position to facilitate the operator to clean the movable ceiling 141 or replace the movable ceiling 141.

[0047] The movable ceiling 141 can at least provide protection for the area of ​​the fixed ceiling close to the iron ladle 300, which helps to reduce the metal blocks on the fixed ceiling mechanism 130 and improve the service life of the fixed ceiling mechanism 130. In addition, after the design of the present application, most of the molten metal splashes on the movable ceiling 141, and the movable ceiling 141 can be raised and lowered under the action of the driving assembly 142, which is also convenient for cleaning the metal blocks.

[0048] The present application forms two layers of protection by setting up the movable ceiling 141 and the fixed ceiling mechanism 130. The movable ceiling 141 blocks most of the molten metal, and the fixed ceiling mechanism 130 blocks the molten metal that is not blocked by the movable ceiling 141. The movable ceiling 141 provides protection for the fixed ceiling mechanism 130, which helps to extend the service life of the fixed ceiling mechanism 130. Under the action of the fixed ceiling mechanism 130 and the movable ceiling 141, the molten metal will not splash onto the charging platform body 110. In addition, the iron ladle 300 and the charging platform body 110 are separated by the fixed ceiling mechanism 130 and the movable ceiling mechanism 140, and the charging platform body 110 is less affected by the temperature of the iron ladle 300. Therefore, the charging platform body 110 will not be affected by the splashing molten metal, and is less affected by the high temperature of the iron ladle 300. The mechanical properties of the charging platform body 110 are more stable and its service life is longer.

[0049] In the present application, the main function of the movable ceiling 141 is to isolate a larger part of the molten metal, and the fixed ceiling mechanism 130 is used to isolate the molten metal that is not isolated by the movable ceiling 141. Therefore, the movable ceiling 141 does not need to cover all areas under the loading platform body 110, but only needs to cover the areas on the fixed ceiling mechanism 130 where slag sticking is more serious.

[0050] Therefore, in some embodiments, the fixed roof mechanism 130 covers all areas below the loading platform body 110 , while the movable roof 141 only covers a certain area around the hopper 120 .

[0051] Of course, the movable roof 141 may also cover the entire area below the loading platform body 110, which is not limited here.

[0052] The driving assembly 142 is used to drive the movable roof 141 to rise or fall, and its structure is diverse and is not limited here.

[0053] For example, the driving assembly 142 may include a gear, a rack and a motor. The gear is mounted on the output shaft of the motor, the rack is fixedly mounted on the movable ceiling 141, the rack is vertically arranged, and the movable ceiling 141 is also vertically slidably connected to the loading platform body 110. The motor is mounted on the loading platform body 110, the gear and the rack are meshed, and the motor 1423 can rotate to drive the movable ceiling 141 to rise or fall.

[0054] For another example, the driving assembly 142 may include a hydraulic circuit (hydraulic pump, hydraulic pipe, one-way valve, etc.) and a hydraulic cylinder. The hydraulic circuit controls the lifting of the hydraulic cylinder. The piston rod of the hydraulic cylinder is fixedly connected to the movable roof 141. The mounting seat of the hydraulic cylinder is installed on the loading platform body 110. The hydraulic cylinder is arranged vertically. The movement of the hydraulic cylinder can drive the movable roof 141 to rise or fall.

[0055] In some embodiments, the driving assembly 142 includes a chain 1421 , a drum 1422 and a motor 1423 ; the motor 1423 is installed on the feeding platform body 110 , the drum 1422 is connected to the rotating shaft of the motor 1423 , and the chain 1421 is connected to the drum 1422 and the movable ceiling 141 .

[0056] The reel 1422 is connected to the rotating shaft of the motor 1423 , and the motor 1423 can drive the reel 1422 to rotate. One end of the chain 1421 is fixedly connected to the reel 1422 , and the other end is fixedly connected to the movable ceiling 141 .

[0057] With this design, the motor 1423 rotates to drive the reel 1422 to rotate, so that the chain 1421 can be wound around the reel 1422 or separated from the reel 1422, thereby driving the movable roof 141 to rise or fall.

[0058] Specifically, the motor 1423 drives the drum 1422 to rotate, so that when the chain 1421 is wound around the drum 1422, the movable roof 141 rises. The motor 1423 drives the drum 1422 to rotate, so that when the chain 1421 is separated from the drum 1422, the movable roof 141 descends.

[0059] In some embodiments, the motor 1423 is a reduction motor 1423 .

[0060] In some embodiments, the reel 1422 is fixedly connected to the shaft of the motor 1423 .

[0061] In some embodiments, the reel 1422 is also rotatably connected to the loading platform body 110 to improve the rotation stability of the reel 1422 .

[0062] The cross section of the reel 1422 may be circular, polygonal, etc., which is not limited here. In some embodiments, the cross section of the reel 1422 is circular.

[0063] In some embodiments, the motor 1423 is installed above the feeding platform body 110 , and the driving assembly 142 further includes a guide wheel 1424 , which is rotatably connected to the feeding platform body 110 , and the guide wheel 1424 is used to guide the chain 1421 .

[0064] The guide wheel 1424 is used to guide the chain 1421. The setting of the guide wheel 1424 allows the chain 1421 to roll and rub against the guide wheel 1424, avoiding direct contact between the chain 1421 and the feeding platform body 110, which helps to reduce the friction force on the chain 1421, so that the motor 1423 can drive the movable roof 141 to rise and fall with less force.

[0065] The structure of the guide wheel 1424 is well known to those skilled in the art and will not be described in detail here.

[0066] The number of chains 1421 may be one or more, which is not limited in the present application.

[0067] In some embodiments, Figure 1 and Figure 2 As shown, 4 chains 1421 are provided, and the 4 chains 1421 are evenly arranged on the movable ceiling 141 to ensure the stability of the lifting of the movable ceiling 141. In these embodiments, the motor 1423 is installed on the right side of the hopper 120, and 4 guide wheels 1424 are provided. The chains 1421 and the guide wheels 1424 are arranged one by one. One guide wheel 1424 is provided on each chain 1421, and the guide wheel 1424 is arranged just above the connection between the corresponding chain 1421 and the movable ceiling 141, and the guide wheel 1424 is located above the feeding platform body 110, so that a section of the corresponding chain 1421 located between the guide wheel 1424 and the movable ceiling 141 is vertically arranged, so that a section of the corresponding chain 1421 located between the guide wheel 1424 and the reel 1422 is horizontally arranged.

[0068] In some embodiments, the fixed ceiling mechanism 130 includes multiple first buckle plates 131 and multiple second buckle plates 132; the first buckle plates 131 and the second buckle plates 132 are arranged in sequence, the first buckle plates 131 are fixedly connected to the loading platform body 110, and the second buckle plates 132 are installed on the first buckle plates 131.

[0069] The first gusset plate 131 and the second gusset plate 132 are arranged in sequence, which means that they are arranged in the order of first gusset plate 131 - second gusset plate 132 - first gusset plate 131 - second gusset plate 132 . . . The first gusset plate 131 is fixedly connected to the feeding platform body 110 , and the second gusset plate 132 is installed on the first gusset plate 131 .

[0070] If the fixed ceiling mechanism 130 is an integrated structure, when the fixed ceiling mechanism 130 expands and contracts due to heat, the stress inside the fixed ceiling mechanism 130 is difficult to release, and the fixed ceiling mechanism 130 is easily damaged. Specifically, the connection parts of the fixed ceiling mechanism 130 may be welded open or deformed, causing damage to the fixed ceiling mechanism 130. In these embodiments, the fixed ceiling mechanism 130 is composed of a plurality of first gussets 131 and a plurality of second gussets 132, allowing the first gussets 131 and the second gussets 132 to independently cope with thermal expansion and contraction, thereby reducing the internal stress of the overall structure caused by temperature changes. When the temperature changes, the first gussets 131 and the second gussets 132 can be independently adjusted slightly, which helps to extend the service life of the fixed ceiling mechanism 130. Moreover, after such a design, when a part of the fixed ceiling mechanism 130 is damaged, the first gussets 131 and the second gussets 132 of the corresponding parts can be replaced, which facilitates the maintenance of the fixed ceiling mechanism 130.

[0071] like Figure 3 As shown, in some embodiments, the first gusset plate 131 includes a fixed plate 1311 and a first limiting plate 1312 and a second limiting plate 1313 respectively disposed at both ends of the fixed plate 1311 in the width direction and located above the fixed plate, and the first limiting plate 1312 and the second limiting plate 1313 are both disposed at an angle to and fixedly connected with the fixed plate 1311. The second gusset plate 132 includes a bottom plate 1321 and a first side plate 1322 and a second side plate 1323 respectively disposed at both ends of the bottom plate 1321 in the width direction and located below the bottom plate 1321, and the first side plate 1322 and the second side plate 1323 are both disposed at an angle to and fixedly connected with the bottom plate 1321. The bottom plate 1321 is located above the first limiting plate 1312 and the second limiting plate 1313, and the first side plate 1322 and the second side plate 1323 are respectively disposed between the first limiting plates 1312 and the second limiting plates 1313 of two adjacent first gusset plates 131.

[0072] After this design, Figure 3As shown, the second gusset plate 132 is located above the first gusset plate 131, the first side plate 1322 of the second gusset plate 132 is located between the first limiting plate 1312 and the second limiting plate 1313 of the first gusset plate 131 on the left, and the second side plate 1323 of the second gusset plate 132 is located between the first limiting plate 1312 and the second limiting plate 1313 of the first gusset plate 131 on the right. The second limiting plate 1313 of the first gusset plate 131 on the left limits the first side plate 1322 of the second gusset plate 132, and the first limiting plate 1312 of the second gusset plate 132 on the right limits the second side plate 1323 of the second gusset plate 132.

[0073] With this design, the second buckle plate 132 can be directly placed on two adjacent first buckle plates 131. There is no need for bolt connection or snap-on structure between the second buckle plate 132 and the first buckle plate 131, which facilitates the installation and disassembly of the second buckle plate 132 and the first buckle plate 131.

[0074] The angled arrangement may be a right angle arrangement, an obtuse angle arrangement or an acute angle arrangement. In some embodiments, Figure 3 As shown, the first limiting plate 1312 and the second limiting plate 1313 are both perpendicular to the fixing plate 1311 , and the first side plate 1322 and the second side plate 1323 are both perpendicular to the bottom plate 1321 .

[0075] In some embodiments, the fixed roof mechanism 130 further includes a connecting member 133 , and the connecting member 133 is connected to the fixed plate 1311 and the loading platform body 110 .

[0076] The structure of the connecting member 133 is various and is not limited in this application. Figure 3 As described, in some embodiments, the feeding platform body 110 is formed by connecting I-beams and the like, the connecting piece 133 is in the shape of an elongated strip, the upper end of the connecting piece 133 is welded and fixed to the feeding platform body 110 , and the lower end of the connecting piece 133 is welded and fixed to the fixing plate 1311 .

[0077] In some implementations, the charging platform body 110 is formed by pouring concrete, etc., the connecting piece 133 is in a long strip shape, the upper end of the connecting piece 133 is fixed to the charging platform body 110 by bolts, or when the charging platform body 110 is formed, the upper end of the connecting piece 133 is pre-embedded in concrete. The lower end of the connecting piece 133 is fixed to the fixing plate 1311 by welding.

[0078] By setting the connecting piece 133, the first buckle plate 131 and the second buckle plate 132 can be kept away from the charging platform body 110, and the height of the first buckle plate 131 and the second buckle plate 132 from the iron ladle 300 can be adjusted by adjusting the length of the connecting piece 133.

[0094] The hopper 120 of the ladle charging platform 100 is located directly above the transport track 400, so that the opening at the top of the ladle 300 on the ladle transport vehicle 200 can be aligned with the discharge port 120b of the hopper 120, and the material discharged from the discharge port 120b of the hopper 120 can fall into the ladle 300 through the opening at the top of the ladle 300.

[0095] When the ladle transport vehicle 200 transports the ladle 300 to the bottom of the hopper 120 and the opening at the top of the ladle 300 is aligned with the discharge port 120b of the hopper 120, the ladle transport vehicle 200 stops so that the material in the hopper 120 can fall into the ladle 300. After the material falls into the ladle 300, the ladle transport vehicle 200 is started to transfer the ladle 300 to the subsequent process.

[0096] Since the ladle charging system includes the ladle charging platform 100 mentioned above in the present application, it naturally has all the beneficial effects possessed by the ladle charging platform 100 of the present application, which will not be elaborated here.
