Description

Technical Field

[0001] This application relates to the field of casting production equipment technology, and in particular to a centrifugal casting integrated operation platform. Background Technology

[0002] Vertical centrifugal casting is the main forming method for rotating castings such as rolls. During the casting process, molten iron is poured from the top opening of the centrifuge into the inner cavity of the roller mold that rotates around the vertical axis. Operators need to monitor the equipment operation status and casting conditions in real time in the centrifuge control room, and replenish molten iron in a timely manner according to the casting progress, observe the forming status, and troubleshoot production faults. The operating platform is a special tooling facility for operators to reach the top of the centrifuge to carry out the above operations.

[0003] Currently, there is no dedicated, standardized centrifuge operating platform in the vertical centrifugal casting production process. When operators detect equipment abnormalities or insufficient molten iron in the control room, they need to temporarily use an A-frame ladder to climb to the top of the centrifuge equipment to carry out operations such as replenishing materials, observing the working conditions, and troubleshooting.

[0004] In existing centrifugal casting production, the existing A-frame ladder climbing operation is only a temporary auxiliary tool. There is no reliable fixed connection between the ladder and the centrifuge equipment. During the operation of the centrifuge, high-frequency vibrations are continuously generated. Under the influence of vibration, the ladder is prone to slippage or even tipping over. Operators standing on the ladder do not have a fixed operating position, their working posture is restricted, and they face the risk of falling from height at any time. At the same time, during the vertical centrifugal high-speed casting process, molten iron tumbles and boils, generating a large amount of dust and molten iron splashes. The temporary climbing operation area lacks protective shielding structures and targeted dust removal structures. The splashed high-temperature particles fly directly at the operators, and dust spreads in the work area, further aggravating the safety hazards and occupational health risks of working above. Ultimately, the safety and efficiency of working above the centrifugal casting equipment cannot be guaranteed, making it difficult to meet the safe, efficient, and environmentally friendly production requirements of modern casting enterprises. Summary of the Invention

[0005] To improve the safety and convenience of operations above centrifugal casting, this application provides a comprehensive centrifugal casting operation platform.

[0006] This application provides a centrifugal casting integrated operation platform, which adopts the following technical solution: A centrifugal casting integrated operation platform includes a first platform, a second platform, a positioning and guiding component, and a dust removal component. The first platform is fixedly installed on one side of a centrifuge. The second platform is hoistably installed at the opening of the centrifuge. The positioning and guiding component is located above the centrifuge and is used to guide and position the hoisting and descent of the second platform. The positioning and guiding component includes a positioning column, which is fixedly installed at the opening of the centrifuge. A docking hole is provided on the second platform, and the docking hole is directly opposite the positioning column. The dust removal component is located on one side of the first platform and is used to collect dust generated during the casting process.

[0007] By adopting the above technical solution, the first platform is fixed on one side of the centrifuge for personnel to stand and work, and the second platform can be hoisted and set at the centrifuge opening. Before casting, the second platform is hoisted away as a whole by an overhead crane to expose the centrifuge opening for casting. After casting, the second platform is hoisted back. The positioning and guiding component guides and positions the hoisting and descent of the second platform by the alignment of the positioning column and the docking hole, ensuring that the second platform can be accurately positioned each time it is hoisted back. The dust removal component collects the dust generated during the casting process at the same time, thereby replacing the traditional A-frame ladder climbing operation. Personnel can safely reach the top of the centrifuge via the platform, and the second platform can be hoisted and moved without blocking the casting opening, which meets the dual needs of casting operation and operation above.

[0008] Optionally, the positioning and guiding assembly further includes a guiding part and an adjusting part; the guiding part is located at the centrifuge opening and is used to guide the hoisting and descent of the second platform; a clearance groove is provided on the positioning column, and a clearance slot is provided on the side wall of the docking hole; the guiding part includes a guide slider and an inclined baffle; the guide slider is slidably disposed in the clearance groove; the inclined baffle is hinged in the clearance slot, and under normal conditions, the inclined baffle is in an inclined state to form a guiding surface; the inclined baffle cooperates with the guide slider, and when the second platform descends, the inclined baffle presses the guide slider to move downward; the adjusting part is located on one side of the docking hole and is used to adjust the angle of the inclined baffle.

[0009] By adopting the above technical solution, when the second platform is hoisted and lowered, the inclined baffle hinged in the relief groove is normally in an inclined state and forms a guide surface. The inclined baffle cooperates with the inclined surface of the guide slider in the relief groove of the positioning column. During the descent of the second platform, the inclined baffle squeezes the guide slider to move downward along the relief groove. The adjustment part is located on one side of the docking hole. After the second platform is in place, the angle of the inclined baffle can be adjusted so that the inclined baffle changes from inclined to vertical, thereby releasing the restriction on the guide slider.

[0010] Optionally, the adjustment unit includes a first driving telescopic rod, an adjusting telescopic rod, and an adjusting spring; the first driving telescopic rod is disposed in the clearance groove, and the rodless cavity of the first driving telescopic rod is filled with liquid; when the second platform descends to its position, the movable end of the first driving telescopic rod is compressed; the adjusting telescopic rod is located in the clearance groove, the movable end of the adjusting telescopic rod is hinged to the inclined baffle, and the fixed end is hinged to the side wall of the clearance groove; the rod cavity of the adjusting telescopic rod is filled with liquid; the rodless cavity of the first driving telescopic rod is connected to the rod cavity of the adjusting telescopic rod through a pipeline; the adjusting spring is located in the rod cavity of the adjusting telescopic rod.

[0011] By adopting the above technical solution, when the second platform descends to its position, the liquid in its rodless chamber flows into the rod chamber of the adjusting telescopic rod through the pipeline, driving the movable end of the adjusting telescopic rod to retract. Since the movable end of the adjusting telescopic rod is hinged to the inclined baffle and the fixed end is hinged to the side wall of the relief groove, when the movable end retracts, it drives the inclined baffle to rotate around the hinge point to a vertical state. The entire angle adjustment process is automatically completed through hydraulic linkage by means of the squeezing force of the second platform descending to its position, without the need for additional manual operation.

[0012] Optionally, the dust removal assembly includes an intake fan, an exhaust fan, a dust removal duct, and a dust removal device; the intake fan is located on one side of the first platform and is used to supply air to the work area; the exhaust fan is located on one side of the intake fan and is used to extract dust-laden air; the dust removal duct includes an inlet pipe and an outlet pipe, the inlet pipe being connected to the intake fan and the outlet pipe being connected to the exhaust fan; the dust removal device is located on the dust removal duct and is used to filter dust-laden air.

[0013] By adopting the above technical solution, the intake fan delivers air to the work area through the intake duct and forms an air curtain to suppress the outward diffusion of dust. The exhaust fan draws dust-laden air through the exhaust duct and sends it to the dust removal device for filtration and purification. The intake and exhaust fans work together to form a directional airflow circulation, capturing metal dust and oxide fumes generated during casting from the source, reducing the dust concentration in the work area and improving the working environment.

[0014] Optionally, a first return spring is provided in the clearance groove, and the two ends of the first return spring are fixedly connected to the guide slider and the bottom wall of the clearance groove, respectively; a locking component is provided above the positioning column, and the locking component is used to lock the second platform after the second platform is lowered into position.

[0015] By adopting the above technical solution, when the guide slider moves downward, it compresses the first reset spring to store energy. After the inclined baffle rotates to the vertical state, it no longer squeezes the guide slider. The first reset spring resets and pushes the guide slider to move upward along the clearance groove, providing driving force for the locking component. The locking component is set above the positioning column and locks the second platform after it descends into place, preventing the second platform from shifting due to accidental contact or equipment vibration, and ensuring the safety of personnel standing and working.

[0016] Optionally, the locking assembly includes a locking telescopic rod; the locking telescopic rod is disposed above the positioning post, and the second platform is locked when the movable end of the locking telescopic rod extends.

[0017] By adopting the above technical solution, the locking telescopic rod is set above the positioning column. When its movable end extends, it blocks the second platform to achieve positioning and locking. When the movable end retracts, the locking is released.

[0018] Optionally, the locking assembly further includes a second driving telescopic rod, a first connecting pipe, and a second connecting pipe; the second driving telescopic rod is vertically disposed within the clearance groove and located above the guide slider; when the guide slider is reset upwards, it presses the movable end of the second driving telescopic rod; both the rodless cavity and the rod cavity of the second driving telescopic rod are filled with liquid; a one-way valve is installed on the piston plate of the second driving telescopic rod; a driving spring is disposed in the rodless cavity of the second driving telescopic rod; both the rodless cavity and the rod cavity of the locking telescopic rod are filled with liquid; the two ends of the first connecting pipe are respectively connected to the rodless cavity of the second driving telescopic rod and the rodless cavity of the locking telescopic rod; a first overflow valve is installed on the first connecting pipe; the two ends of the second connecting pipe are respectively connected to the rod cavity of the locking telescopic rod and the rod cavity of the second driving telescopic rod; a second overflow valve is installed on the second connecting pipe.

[0019] By adopting the above technical solution, when the inclined baffle drives the guide slider to move downward, the drive spring resets, and the liquid in the rod chamber of the second drive telescopic rod flows to the rodless chamber through the one-way valve; when the guide slider resets upward, it squeezes the movable end of the second drive telescopic rod, the drive spring is in a compressed state, and the liquid in the rodless chamber of the second drive telescopic rod flows into the rodless chamber of the locking telescopic rod through the first connecting pipe and the first overflow valve, driving the movable end of the locking telescopic rod to extend to lock the second platform, and the liquid in the rod chamber of the locking telescopic rod flows back to the rod chamber of the second drive telescopic rod through the second connecting pipe and the second overflow valve, forming a closed hydraulic circuit. The entire locking process is automatically triggered by the reset action of the guide slider.

[0020] Optionally, a return pipe is connected between the rod-side chamber and the rodless chamber of the locking telescopic rod, and a pressure relief valve is installed on the return pipe; a second return spring is provided in the rod-side chamber of the locking telescopic rod.

[0021] By adopting the above technical solution, when the movable end of the locking telescopic rod extends, the second return spring is in a compressed state. When it is necessary to lift the second platform, the pressure relief valve on the return pipe is opened, the second return spring is reset, and the liquid in the rodless chamber of the locking telescopic rod is depressurized and flows back to the rod chamber through the return pipe. The movable end retracts and releases the lock on the second platform, which can then be lifted by the overhead crane. The unlocking operation is simple.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a second platform, the entire structure is lifted away before casting to expose the opening, and then lifted back after casting. The positioning column and the docking hole work together to guide and position the lifting and lowering, taking into account both the needs of casting operations and personnel operating above. 2. By setting up positioning guide components and locking components, when the second platform descends, the inclined baffle squeezes the guide slider to store energy. After reaching the position, the hydraulic drive of the inclined baffle rotates to the vertical position to release the guide slider. The guide slider resets and is then automatically locked by hydraulically driving the locking telescopic rod to extend. No additional manual operation is required throughout the process. After locking, the second platform can be prevented from shifting due to accidental contact or vibration. 3. By setting up an intake fan and an exhaust fan, a directional airflow circulation is formed. The air curtain suppresses dust overflow, and the negative pressure draws out dusty air and filters and purifies it through a dust removal device, thus controlling the spread of casting dust from the source and meeting environmental emission requirements.

[0025] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0026] This application discloses a comprehensive centrifugal casting operation platform. (Refer to...) Figure 1 and Figure 2 A centrifugal casting integrated operation platform includes a first platform 1, a second platform 2, a positioning and guiding component 3, a dust removal component 4, and a locking component 5.

[0027] Reference Figure 1 , Figure 3 and Figure 4 The first platform 1 is fixedly installed on one side of the centrifuge and next to the centrifuge operating room. Operators can access the first platform 1 via a ladder after exiting the operating room. The second platform 2 is hoisted and installed at the centrifuge opening. It is lifted away by an overhead crane before casting and returned to its original position after casting. A positioning and guiding assembly 3 is located at the centrifuge opening and is used to guide and position the second platform 2 during hoisting and descent. A dust collection assembly 4 is located on one side of the first platform 1 and is used to collect dust generated during the casting process. A locking assembly 5 is located at the centrifuge opening and is used to lock the second platform 2. The first platform 1 is equipped with railings and a closed protective barrier, forming a ring-shaped protective barrier to block splashes of high-temperature molten iron and dust during casting. The platform surface of the first platform 1 is made of checkered plate for anti-slip and wear-resistant properties. The top surface of the first platform 1 is flush with the top surface of the second platform 2. After the second platform 2 is hoisted back into position, operators can directly walk from the first platform 1 to the second platform 2. A steel chain is installed on the first platform 1 and the second platform 2, and a steel plate is laid in the middle area enclosed by the steel chain as the platform surface.

[0028] Reference Figure 1 and Figure 2The positioning guide assembly 3 includes positioning posts 31, guide parts 32, and adjustment parts 33. Positioning posts 31 are fixedly installed at the centrifuge opening. Multiple positioning posts 31 are spaced apart circumferentially along the centrifuge opening; in this embodiment, six are arranged in six equal parts along the centrifuge opening. The second platform 2 has docking holes 21 that are directly opposite the positioning posts 31. When the second platform 2 is hoisted and lowered, the docking holes 21 are fitted into the positioning posts 31. The positioning posts 31 have clearance grooves 311, and the side walls of the docking holes 21 have clearance grooves 22.

[0029] Reference Figure 2 The guide section 32 includes a guide slider 321, an inclined baffle 322, and a first return spring 323. The guide slider 321 is slidably disposed in the clearance groove 311, and its ends are provided with guide slopes. In this embodiment, the guide slider 321 is rectangular, and the ends of the guide slider 321 are provided with guide slopes. Two sets of corresponding clearance grooves 22, inclined baffles 322, and adjustment sections 33 are provided, and they are respectively located on both sides of the guide slider 321. In other embodiments, the guide slider 321 may be cross-shaped, and the four ends of the guide slider 321 are provided with guide slopes. Four sets of corresponding clearance grooves 22, inclined baffles 322, and adjustment sections 33 are provided, and they are respectively located in the four directions of the guide slider 321.

[0030] The inclined baffle 322 is hinged in the relief groove 22, and the first return spring 323 is located in the relief slide 311. The two ends of the first return spring 323 are fixedly connected to the guide slider 321 and the bottom wall of the relief slide 311, respectively. Under normal conditions, the inclined baffle 322 is in an inclined state and forms a guide surface. The inclined baffle 322 cooperates with the inclined surface of the guide slider 321. When the second platform 2 descends, the inclined baffle 322 squeezes the guide slider 321 to move downward along the relief slide 311 and compresses the first return spring 323.

[0031] Reference Figure 2The adjustment unit 33 includes a first drive telescopic rod 331, an adjustment telescopic rod 332, and an adjustment spring 333. The first drive telescopic rod 331 is disposed within the clearance groove 22, with its movable end passing through the bottom wall of the second platform 2. The rodless cavity of the first drive telescopic rod 331 is filled with liquid. When the second platform 2 descends to its final position, the movable end of the first drive telescopic rod 331 is compressed. The adjustment telescopic rod 332 is located within the clearance groove 22. The movable end of the adjustment telescopic rod 332 is hinged to the inclined baffle 322, and the fixed end of the adjustment telescopic rod 332 is hinged to the side wall of the clearance groove 22. The rod cavity of the adjustment telescopic rod 332 is filled with liquid. The rodless cavity of the first drive telescopic rod 331 is connected to the rod cavity of the adjustment telescopic rod 332 via a pipeline. The adjustment spring 333 is located within the rod cavity of the adjustment telescopic rod 332 and is used for the reset of the adjustment telescopic rod 332. When the second platform 2 descends to its position, the movable end of the first drive telescopic rod 331 is compressed, and the liquid in its rodless chamber flows into the rod chamber of the adjusting telescopic rod 332 through the pipeline, driving the movable end of the adjusting telescopic rod 332 to retract. Since the movable end of the adjusting telescopic rod 332 is hinged to the inclined baffle 322 and the fixed end is hinged to the side wall of the relief groove 22, when the movable end retracts, it drives the inclined baffle 322 to rotate around the hinge point to a vertical state, releasing the limitation on the guide slider 321.

[0032] Reference Figure 1 The dust removal assembly 4 includes an inlet fan 41, an induced draft fan 42, a dust removal duct 43, and a dust removal device 44. The inlet fan 41 is located on one side of the first platform 1 and is used to supply air to the work area; the induced draft fan 42 is located on one side of the inlet fan 41 and is used to extract dust-laden air. The dust removal duct 43 includes an inlet pipe 431 and an outlet pipe 432. The inlet pipe 431 is connected to the inlet fan 41, and the outlet pipe 432 is connected to the induced draft fan 42. The dust removal device 44 is installed on the dust removal duct 43 and is used to filter dust-laden air. The dust removal device 44 can be a bag filter, cyclone filter, or cartridge filter, or other commonly used industrial dust removal equipment. The inlet fan 41 supplies air to the work area through the inlet pipe 431 and forms an air curtain to suppress the outward diffusion of dust. The induced draft fan 42 draws the dust-laden air to the dust removal device 44 for filtration and purification through the outlet pipe 432. The inlet and induced draft fans work together to form a directional airflow circulation.

[0033] Reference Figure 2The locking assembly 5 includes a locking telescopic rod 51, a second driving telescopic rod 52, a first connecting pipe 53, a second connecting pipe 54, and a return pipe 55. The locking telescopic rod 51 is positioned above the positioning post 31. Both the rodless and rod-side chambers of the locking telescopic rod 51 are filled with liquid. When the movable end of the locking telescopic rod 51 extends, it locks the second platform 2; when the movable end of the locking telescopic rod 51 retracts, it releases the lock. A second return spring 511 is installed in the rod-side chamber of the locking telescopic rod 51. The second driving telescopic rod 52 is vertically positioned within the clearance groove 311 and above the guide slider 321. Both the rodless and rod-side chambers of the second driving telescopic rod 52 are filled with liquid. A one-way valve 521 is mounted on the piston plate of the second driving telescopic rod 52, and a driving spring 522 is installed in the rodless chamber of the second driving telescopic rod 52. The first connecting pipe 53 has two ends connected to the rodless chamber of the second driving telescopic rod 52 and the rodless chamber of the locking telescopic rod 51, respectively, and a first relief valve 531 is installed on the first connecting pipe 53. The second connecting pipe 54 has two ends connected to the rod chamber of the locking telescopic rod 51 and the rod chamber of the second driving telescopic rod 52, respectively, and a second relief valve 541 is installed on the second connecting pipe 54. The return pipe 55 connects the rod chamber and the rodless chamber of the locking telescopic rod 51, and a pressure relief valve 551 is installed on the return pipe 55. The pressure relief valve 551 can be a solenoid valve or a manual butterfly valve.

[0034] During the descent of the second platform 2, the elastic force of the adjusting spring 333 is greater than that of the first reset spring 323. The inclined baffle 322 presses the guide slider 321 to move downward along the clearance groove 311. The guide slider 321 gradually disengages from the movable end of the second drive telescopic rod 52. The drive spring 522 releases and drives the movable end of the second drive telescopic rod 52 to extend. The liquid in the rod chamber of the second drive telescopic rod 52 flows to the rodless chamber through the one-way valve 521 on the piston plate. When the inclined baffle 322 rotates to a vertical position under the drive of the adjusting part 33, the guide slider 32... When the limit is released, the first return spring 323 resets and pushes the guide slider 321 upward. The guide slider 321 squeezes the movable end of the second drive telescopic rod 52. The liquid in the rodless chamber of the second drive telescopic rod 52 flows into the rodless chamber of the locking telescopic rod 51 through the first connecting pipe 53. The movable end of the driving locking telescopic rod 51 extends and locks the second platform 2. The second return spring 511 is in a compressed state. The liquid in the rod chamber of the locking telescopic rod 51 flows back to the rod chamber of the second drive telescopic rod 52 through the second connecting pipe 54, forming a closed hydraulic circuit. When it is necessary to lift the second platform 2, the pressure relief valve 551 is opened. The second return spring 511 resets, and the liquid in the rodless chamber of the locking telescopic rod 51 is depressurized and flows back to the rod chamber through the return pipe 55. The movable end of the locking telescopic rod 51 retracts and is unlocked.

[0035] The implementation principle of the centrifugal casting integrated operation platform in this application embodiment is as follows: Before the casting operation, the overhead crane lifts the second platform 2 away from the centrifuge opening, exposing the top opening of the centrifuge. Molten iron is poured into the rotating roller mold cavity from the opening for centrifugal casting. The dust removal component 4 operates synchronously. The air inlet fan 41 sends air to the work area through the air inlet pipe 431 to form an air curtain. The exhaust fan 42 draws out the dust-laden air through the air outlet pipe 432 and sends it to the dust removal device 44 for filtration and purification.

[0036] After casting is completed, when operators need to work above the centrifuge, the overhead crane hoists the second platform 2 above the centrifuge opening and slowly lowers it. The docking hole 21 on the second platform 2 is aligned with the positioning post 31. The inclined baffle 322 first contacts the guide slider 321 and engages with it along the inclined surface, squeezing the guide slider 321 to move downward along the clearance groove 311 and compressing the first return spring 323. When the second platform 2 continues to descend to its final position, the movable end of the first drive telescopic rod 331 in the clearance groove 22 is squeezed, and the liquid in its rodless chamber flows into the regulating extension through the pipeline. The rod chamber of the retracting rod 332 drives the movable end of the adjusting telescopic rod 332 to retract, causing the inclined baffle 322 to rotate from an inclined state to a vertical state. The inclined baffle 322 releases the limit on the guide slider 321, and the first reset spring 323 pushes the guide slider 321 upward to reset. The guide slider 321 squeezes the movable end of the second driving telescopic rod 52, and the liquid in the rodless chamber of the second driving telescopic rod 52 flows into the rodless chamber of the locking telescopic rod 51 through the first connecting pipe 53, driving the movable end of the locking telescopic rod 51 to extend and automatically lock the second platform 2. After locking, the operator comes out of the centrifuge operating room and climbs the ladder to the first platform 1. Since the top surfaces of the first platform 1 and the second platform 2 are flush, the operator walks directly from the first platform 1 to the second platform 2 to carry out operations such as material replenishment, working condition observation, and fault diagnosis. The railings and enclosed protective baffles block splashing high-temperature molten iron and dust.

[0037] When casting is required after the work is completed, open the pressure relief valve 551 on the return pipe 55, lock the rodless chamber of the telescopic rod 51 to release the pressure, lock the movable end of the telescopic rod 51 to retract and release the lock, and the crane will lift the second platform 2 as a whole to expose the centrifuge opening so that the next round of casting can be carried out.

[0038] 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.
