Abstract
Description
Technical Field
[0001] This invention relates to the field of cast iron machine technology, and in particular to a high-efficiency production device and method for cast iron machines. Background Technology
[0002] Cast iron machines are mainly used in the steel and metallurgical industries. The working process is as follows: a locomotive transports molten iron ladles or mixed iron ladles from the blast furnace to the cast iron machine workshop via railway locomotive or automobile. The molten iron ladle is tilted by a tilting mechanism, and the molten iron flows into the cast iron mold through the molten iron trough. The cast iron mold filled with molten iron is slowly moved upward by the chain belt. During the transportation process, the cooling device sprays cooling water on the already crusted iron blocks to accelerate the cooling of the iron blocks. The iron blocks fall off at the star wheel at the head of the machine and are slid into the transport car by the chute and transported out. Individual iron blocks that are not easy to fall off are cleaned off by the iron-removing device. When the chain belt returns, mortar is continuously sprayed into the cast iron mold to facilitate the demolding of the iron blocks.
[0003] Nowadays, the molten iron ladle is tilted by a rotating plate on the front support of the casting machine. The rotating plate causes the molten iron ladle to tilt, resulting in less molten iron splashing, higher molten iron recovery rate, and less environmental pollution.
[0004] Currently, iron casting machines are becoming increasingly sophisticated. The main factor restricting the efficiency of iron casting is its supporting system. Due to space limitations, the front support cannot automatically tension the rotating plate. Workers need to use shims to rotate the plate, which is time-consuming and labor-intensive. Furthermore, the operators are not effectively protected, which seriously affects the efficiency of iron casting and results in low overall construction efficiency. Summary of the Invention
[0005] The purpose of this invention is to overcome the shortcomings of the current casting machine production process, which is characterized by low overall efficiency and seriously affects the efficiency of casting iron production. Therefore, this invention proposes a high-efficiency casting machine production device and method.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A high-efficiency production device and method for a cast iron machine includes a support, a front support column on the support, a chute and a cast iron machine on one side of the front support column, a slag pit on one side of the chute, a rotating plate on the front support column, a spherical chain connected to the rotating plate, a support frame on the side of the front support column, a roller connected to the support frame, the spherical chain passing through the roller and connected to a hanging shaft, and a counterweight on the hanging shaft.
[0008] By incorporating a spherical chain, a hanging shaft, and a counterweight, the original space limitation problem was solved. In particular, the spherical design of the chain ball effectively reduces frictional resistance, increases service life, and effectively solves the problem of low operating efficiency.
[0009] Preferably, a tray is connected below the lifting shaft, and a counterweight is placed on the tray. The counterweight has an elongated slot that corresponds to the lifting shaft.
[0010] The tray supports the counterweight, and the elongated slot makes it easy to pass the counterweight through the lifting shaft.
[0011] Preferably, the spherical chain includes multiple spheres, each sphere is connected to a pin, and each pin has two connecting plates connected to both ends. One end of each connecting plate is connected to the pin of another sphere.
[0012] The sphere, connecting plate, and pin are assembled into a chain with a length of mm, which connects the hanging shaft and the hanging ring to transmit tension.
[0013] Preferably, the support includes a lower base plate, with two first stiffening plates connected to the upper surface of the lower base plate, two second stiffening plates connected between the two first stiffening plates, and a third stiffening plate connected to the opposite sides of the two first stiffening plates. The lower end of the third stiffening plate is connected to the lower base plate, and the upper ends of the two first stiffening plates are connected to an upper base plate. An adjusting pad is connected to the upper base plate.
[0014] The front and rear long groove structure of the lower base plate, the left and right long groove structure of the upper base plate, and the paired inclined surface structure of the adjustment pad are used to adjust the front, back, left, right and up dimensions of large workpieces. In particular, the integration of the three structures enables on-site three-dimensional adjustment of large workpieces, which solves the problem of time-consuming and labor-intensive matching during trial installation and greatly improves installation efficiency.
[0015] Preferably, the adjusting pad includes two inclined pads with their inclined surfaces abutting each other, and each of the four corners of the two pads is provided with a connecting slot.
[0016] Preferably, a movable component is provided on the slag pit. The movable component includes a movable plate, and rollers are connected to the bottom of the movable plate. Guide rails are provided on both side walls of the slag pit, and the rollers are connected to the guide rails.
[0017] The roller bracket and pin are fixed by welding after installation, which simplifies the process and makes it easy to use. The bracket is welded to the inner side of the surrounding beam in a staggered manner, which effectively reduces the thickness of the movable cover plate, achieving a compact yet load-bearing effect with high efficiency and good safety.
[0018] Preferably, the guide rail is V-shaped, with its upper end abutting against the lower surface of the roller.
[0019] Preferably, an operating room is provided on the movable plate, and four seventh angle steels are provided on the side wall of the operating room. A movable baffle is provided between the four seventh angle steels, and two second tempered glass panels are provided on the side wall of the operating room.
[0020] Preferably, a monitoring room is provided on one side of the iron casting machine, and the monitoring room is equipped with two first tempered glass panels.
[0021] A method for high-efficiency production equipment for a cast iron machine includes the following steps:
[0022] S1: Install the support on the foundation, then install the front support on the support, so that the connecting bolts are connected to the middle positions of the long slots in the lower and upper base plates respectively, and tighten the nuts; use a locomotive to transport the empty molten iron ladle to the front of the front support, and tilt the empty molten iron ladle along the locomotive axle. Stop when the empty molten iron ladle is about to hit the locomotive frame. At this time, measure the three-dimensional coordinate dimension between the side lug of the molten iron ladle and the rotating plate. The measurement reference is the uppermost point of the inner arc surface of the side lug and the uppermost point of the circumference of the rotating plate. Record the front-back, left-right, and up-down dimensions respectively; loosen the nuts and adjust the front-back and left-right positions of the support according to the measurement results. Add 10mm-20mm as the thickness of the adjusting shim according to the up-down dimensions. Add the adjusting shim, and finally tighten the bolts. The front support and support are now installed.
[0023] S2: Weld the lifting ring of the tensioning device to the inner side of the rotating plate, and adjust the number of counterweights so that the rotating plate can rotate freely under the action of the counterweights;
[0024] S3: Start the iron casting machine and put it into operation. Tilt the iron ladle containing molten iron. When the iron ladle tilts along the rotating plate, the molten iron slowly flows into the chute and then into the iron casting mold of the iron casting machine through the spout.
[0025] S4: The operator monitors the flow of molten iron and the working status of the casting machine through the first tempered glass in the monitoring room.
[0026] S5: When it is found that the flow of molten iron is not smooth, the operator goes to the control room to open the movable baffle and cleans the chute and spout with an iron rake. After the flow of molten iron is normal, the movable baffle is closed, and then the flow of molten iron is observed through the second tempered glass. After the flow of molten iron is stable, the operator returns to the control room to continue to monitor the flow of molten iron and the working status of the iron casting machine.
[0027] S6: When the slag pit needs to be cleaned, push the moving plate along the guide rail to clean the slag. After cleaning, reset the moving plate and continue casting iron.
[0028] Compared with the prior art, the beneficial effects of the present invention are: rapid installation of the front support, automatic tensioning of the rotating plate, safe monitoring of the molten iron flow status, safe cleaning of the molten iron chute and molten iron spout, and efficient cleaning of waste residue, thus realizing the efficient and safe operation of the cast iron machine supporting system.
