Description

Technical Field

[0001] The present application belongs to the technical field of metallurgical processing equipment, and in particular relates to a folding platform of a tilting machine. Background Art

[0002] Steelmaking and continuous casting is the main process of the whole process of modern steel production. After the ladle receives the molten steel from the converter, it has been accompanying the steelmaking and continuous casting production process, playing an important role in energy saving and consumption reduction. The ladle itself is not only a container for high-temperature molten steel in the steelmaking and continuous casting process, but also a reactor for various physical and chemical reactions. Its importance to the quality of molten steel is self-evident. Ladle hot repair requires hot repair of the ladle, mainly to treat the ladle water inlet and bottom blowing bricks and inspect the ladle lining.

[0003] During the smelting process of the metallurgical industry, the ladle nozzle operation requires the use of a tilting machine for auxiliary work. The tilting machine is a device used to pour molten metal or other materials from the furnace into the pouring equipment, or to pour it out of the furnace when processing slag. The tilting machine needs to work on a platform, and the process requires manual processing of the platform. The existing platform is generally fixed on the ground and cannot be moved. The hot repair operation of the ladle tilting machine is very inconvenient, and manual operation on the platform will also have certain safety hazards. Utility Model Content

[0004] The present application aims to at least to some extent solve the technical problem that the existing platforms are inconvenient to operate. To this end, the present application provides a folding platform for a tilting machine, which can conveniently adjust the distance between the platform and the furnace. Before operating on the platform, an operating area is provided. The construction position of the tilting machine can be determined according to actual construction needs. This makes it convenient for manual operation on the platform, while eliminating the need to build a platform. The operation can be carried out quickly, thereby improving work efficiency.

[0005] The embodiment of the present application provides a folding platform of a tilting machine, which comprises:

[0006] Platform foundation, including platform plates and folding plates hinged to each other;

[0007] The supporting assembly includes a fixed base, a driver and a platform turning seat. The fixed base is connected to the platform plate, the platform turning seat is connected to the folding plate, the two ends of the driver are respectively hinged to the fixed base and the platform turning seat, and the driver is a retractable structure; the folding plate is driven by the driver to rotate relative to the platform plate.

[0008] The existing tilting machine is operated on a platform, but for safety reasons, the platform cannot be in contact with the furnace, so it cannot be built in advance. The existing platforms are generally temporary. Due to the difficulty of lifting and the waste of time, it is very inconvenient to build a platform first when performing hot repair operations on the ladle tilting machine, and the tilting machine needs to be adjusted to a suitable position. In order to complete the operation, a temporary platform is built and then dismantled after use. However, the whole process is labor-intensive and there are certain safety hazards. In this application, the platform foundation is separated from the furnace during non-working hours, which meets the requirements. When needed, the folding plate rotates through the support group The folding plate can be opened and closed for storage after being opened, and a section can be added to the edge of the platform plate to facilitate adjustment of the distance between the platform and the furnace, thereby providing an operating area. The construction position of the tilting machine can be determined according to actual construction needs, which makes it convenient for manual operation on the platform. At the same time, since there is no need to temporarily build a platform to connect with the furnace, the platform is built in advance, and the folding plate can be rotated when construction is needed. The operation is faster and more convenient, which improves work efficiency and reduces the work intensity of operators.

[0009] In an optional embodiment, when the telescopic structure of the driver reaches the shortest stroke, the inclination angle of the folding plate relative to the surface where the platform plate is located is [0°, 15°].

[0010] In an optional embodiment, when the telescopic structure of the driver reaches the maximum stroke, the angle between the folding plate and the platform plate is [75°, 105°].

[0011] In an optional embodiment, the cantilever end of the folding plate is provided with an opening for objects to pass through.

[0012] In an optional embodiment, the folding plate is further provided with a cover plate, which is hinged to the cantilever end of the folding plate, and the opening can be covered by the cover plate.

[0013] In an optional embodiment, the folding plate has a length of [4000mm, 5000mm] and a width of [800mm, 1200mm].

[0014] In an optional embodiment, the opening is set to have a length of [800mm, 1200mm] and a width of [150mm, 450mm].

[0015] In an alternative embodiment, the drive comprises a linear stepper motor, a hydraulic cylinder, an electric cylinder or a pneumatic cylinder.

[0016] In an optional embodiment, the support assembly further comprises a power supply connection member for providing power to the drive, the power supply connection member being connected to the drive.

[0017] In an optional embodiment, the platform foundation further includes guardrails, and the edges of the platform plate and the folding plate are respectively provided with guardrails.

[0018] It can be seen from the above technical solution that the beneficial effects of this application are:

[0019] When needed, the folding plate of the tilting and folding platform is rotated by the supporting assembly, and the telescopic structure of the driver is used to drive the folding plate to rotate relative to the platform plate, so as to provide the folding plate for opening and use and closing and storage. After the folding plate is opened, a section can be added to the edge of the platform plate, which is convenient for adjusting the distance between the platform and the furnace, and provides an operation area. The construction position of the tilting machine can be determined according to actual construction needs, which can facilitate manual operation on the platform. At the same time, since there is no need to temporarily build a platform to connect with the furnace, the platform is built in advance, and the folding plate can be rotated when construction is needed. The operation is faster and more convenient, which improves work efficiency and reduces the workload of operators. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0031] Please refer to Figure 1 and Figure 2In a first aspect of the present application, a folding platform 100 of a tilting machine is provided, which includes: a platform foundation 110 and a support assembly 120, the support assembly 120 is arranged at the bottom of the platform foundation 110, the platform foundation 110 is the working area of ​​the tilting machine, the platform foundation 110 includes a platform plate 112 and a folding plate 113 which are hinged to each other, the folding plate 113 is located at the edge of the platform plate 112, and a section is added on the basis of the original platform, the top edge of the folding plate 113 is connected to the top edge of the platform plate 112 through a hinge, and the hinge can be a bearing hinge, a latch hinge, a hinge, etc., as long as the folding plate 113 can rotate relative to the platform plate 112, when the folding plate 113 is flush with the platform plate 112, one side of the folding plate 113 is aligned with the platform plate 112 The edges of the folding plate 113 abut against each other, and the folding plate 113 and the platform plate 112 are balanced at this position, which is the initial rotation position of the folding plate 113; the support assembly 120 provides support at the bottom of the platform foundation 110 and can drive the folding plate 113 to rotate. Since the support assembly 120 works at the bottom of the platform foundation 110, a certain torque must be provided. In order to facilitate the installation and operation of the driver 122, a mounting seat needs to be provided; the support assembly 120 provides a steering force for the rotation of the folding plate 113, drives the folding plate 113 to be in an open and closed state, and provides a supporting force at the bottom of the folding plate 113. When the folding plate 113 is opened, the folding plate 113 is flush with the platform plate 112 to provide a working area. When the folding plate 113 is closed, the folding plate 113 rotates to a certain angle with the platform plate 112, and the folding plate 113 is retracted.

[0032] Please refer to Figure 3The support assembly 120 includes a fixed base 121, a driver 122 and a platform steering seat 124. The driver 122 is a retractable structure. The two ends of the driver 122 are respectively hinged to the fixed base 121 and the platform steering seat 124. The fixed base 121 is connected to the platform plate 112, and the platform steering seat 124 is connected to the folding plate 113. The fixed base 121 is welded to the bottom of the platform plate 112, and the fixed base is provided with a through hole for hinged setting. One end of the driver 122 is hinged to the fixed base through the through hole, and a latch-type connection method can be adopted. The volume of the platform steering seat 124 is larger than the fixed base 121 to provide torque. The top of the platform steering seat 124 is welded to the bottom of the folding plate 113, and the platform steering seat 124 is provided with a through hole for hinged setting. The other end of the driver 122 is hinged to the platform steering seat 124 through the through hole, and a latch-type connection method can be adopted; in addition to the above-mentioned hinge method, other hinge methods can also be set between the fixed base 121 and the driver 122, and between the platform steering seat 124 and the driver 122, as long as it is ensured that the driver 122 can rotate relative to the fixed base 121 and relative to the platform steering seat 124, so that the folding plate 113 can rotate relative to the fixed base 121 and relative to the platform steering seat 124. The actuator 122 drives the rotation relative to the platform plate 112, and the folding plate 113 can be opened and closed by rotation; the hinge point between the driver 122 and the fixed base 121 is recorded as the first hinge point, and the hinge point between the driver 122 and the platform steering seat 124 is recorded as the first hinge point, and the distance between the second hinge point and the platform plate 112 is smaller than the distance between the second hinge point and the folding plate 113, so that the second hinge point has a larger stroke, which is convenient for the driver 122 to drive the folding plate 113 to rotate to a certain angle; in other embodiments, the platform steering seat 124 is provided with a structure that bends toward the driver 122. This setting is mainly to consider matching the length and position of the driver 122, so that when the folding plate 113 needs to be closed, the driver 122 can drive the folding plate 113 to rotate a larger angle to fold the folding plate 113 as much as possible. In an optional embodiment, the driver 122 includes a linear stepper motor, a hydraulic cylinder, an electric cylinder or a pneumatic cylinder. The driver 122 can select a variety of different devices, all of which are retractable structures and can achieve extension and shortening of length through corresponding driving methods, thereby adjusting the distance between the first hinge point and the second hinge point, that is, adjusting the stroke of the driver 122.

[0033] In the present application, during non-working hours, the platform foundation 110 is spaced apart from the furnace, which meets the requirements. When necessary, the rotation of the folding plate 113 is realized by the support assembly 120, and the telescopic structure of the driver 122 drives the folding plate 113 to rotate relative to the platform plate 112, thereby providing the folding plate 113 for opening and use and closing and storage. After the folding plate 113 is opened, a section can be added to the edge of the platform plate 112, which is convenient for adjusting the distance between the platform and the furnace, and provides an operation area. The construction position of the tilting machine can be determined according to actual construction needs, which can facilitate manual operation on the platform; at the same time, since there is no need to temporarily build a platform to connect with the furnace, the platform is built in advance, and the folding plate 113 can be rotated when construction is needed, which is faster and more convenient to operate, improves work efficiency, and reduces the work intensity of the operator; on the other hand, since the tilting machine can stably match the operating position of the furnace, the bottom of the folding plate 113 is supported by the support assembly 120, which can ensure safe and stable operation, and does not need to build a temporary platform, which also improves safety.

[0034] In an optional embodiment, the overall structural size of the platform foundation 110 can be large or small, and the size of the support assembly 120 can also be large or small. Specifically, the size of the fixed base 121, the driver 122 and the platform steering seat 124 is determined and manufactured according to the on-site requirements. The size of each component does not limit the present application. For the convenience of explanation, the size described in the following embodiments is an implementable size, which is only used as an example. In an optional embodiment, the size of the fixed base 121 and the size of the platform steering seat 124 are determined according to the site, and can be determined according to the bottom space of the platform plate 112 and the folding plate 113. The fixed base 121 and the platform steering seat 124 are made of high-strength steel plates; the driver 122 adopts a hydraulic cylinder, which is oil-pressure driven. In the initial state, the entire length of the driver 122 at the shortest stroke is 1350mm. The driver 122 has a hydraulic rod with a performance level of 8.8. The hinges of the driver 122, the fixed base 121 and the platform steering seat 124 use high-strength bolts. The distance between the first hinge point and the second hinge point is adjusted by the hydraulic rod, thereby driving the folding plate 113 to rotate. In an optional embodiment, the support assembly 120 also includes an energy supply connector 123 for providing power to the driver 122. The energy supply connector 123 is connected to the driver 122. For example, when the driver 122 is a hydraulic cylinder, the energy supply connector 123 uses a hydraulic pipe, which is connected to the oil cylinder in the driver 122. The other end of the hydraulic pipe is connected to a hydraulic source. In this way, driving force can be provided to the driver 122 through the energy supply connector 123.

[0035] In an optional embodiment, when the retractable structure of the driver 122 reaches the shortest stroke, the inclination angle of the folding plate 113 relative to the surface of the platform plate 112 is [0°, 15°]. The best embodiment is that when the driver 122 reaches the shortest stroke, the folding plate 113 is flush with the platform plate 112. At a smaller angle within 15°, construction operations can also be carried out, but the effect is not as good as the aforementioned situation. This setting can ensure that when the folding plate 113 is in a fully opened state, the bottom of the folding plate 113 can be supported by the driver 122 to prevent the folding plate 113 from rotating downward, which can ensure safety to a certain extent. In an optional embodiment, when the retractable structure of the driver 122 reaches the maximum stroke, the angle between the folding plate 113 and the platform plate 112 is [75°, 105°]. The best embodiment is that when the driver 122 reaches the maximum stroke, the folding plate 113 and the platform plate 112 are 90°, so that the folding plate 113 is in a closed state, and the main weight of the folding plate 113 is supported by the platform plate 112, which reduces the force applied to the driver 122 and minimizes the impact of the furnace on the platform, thereby ensuring the premise of pre-building the platform; at other angles, although the folding plate 113 can also be folded to a certain extent, the effect is not as good as the aforementioned case.

[0036] In an optional embodiment, the length of the folding plate 113 is [4000mm, 5000mm] and the width is [800mm, 1200mm]; the length of the folding plate 113 is 4500mm and the width is 1000mm, and the size of the platform plate 112 is larger than the folding plate 113; in an optional embodiment, the platform plate 112 and the folding plate 113 are profiled plates, and the interior of the profiled plates is a hollow structure, which can reduce the weight of the entire platform foundation 110. In an optional embodiment, the length of the opening 113a is [800mm, 1200mm] and the width is [150mm, 450mm], and the size of the opening 113a is smaller than the folding plate 113. The best implementation is that the size of the opening 113a is as small as possible, as long as it can throw out waste objects. For example, when used to throw refractory materials, the size of the opening 113a can be slightly larger than the size of the refractory materials.

[0037] Please refer to Figure 4In an optional embodiment, the cantilever end of the folding plate 113 is provided with an opening 113a, and the opening 113a is used for objects to pass through. Specifically, the setting of the opening 113a is convenient for throwing out discarded materials, such as throwing waste refractory materials into the pit under the platform foundation 110; the length of the opening 113a is 1000mm and the width is 300mm. The size of the opening 113a can be set according to actual needs. In an optional embodiment, the folding plate 113 is also provided with a cover plate 113b, and the cover plate 113b is hinged to the cantilever end of the folding plate 113. The hinge adopts a conventional hinge connection method. The opening 113a can be blocked by the cover plate 113b, so that the cover plate 113b can be rotated to close the opening 113a to form a shielding, thereby ensuring the safety of operation on the folding plate 113. At the same time, it is also convenient to throw out the waste refractory materials.

[0038] In an optional embodiment, the platform foundation 110 also includes a guardrail 114, and the edges of the platform plate 112 and the folding plate 113 are respectively provided with a guardrail 114; on the platform plate 112 except the edge connected to the folding plate 113, the guardrail 114 is welded, and the guardrail 114 is also welded on both sides of the folding plate 113. The height of the guardrail 114 is 1000 mm, and it is formed by welding a steel pipe with a diameter of 40 mm to form a fence. The guardrail 114 can ensure operational safety. In an optional embodiment, the platform foundation 110 also includes a column 111, which is a structure supporting the ground at the working position. The bottom end of the column 111 is fixed to the ground with screws, and the top of the column 111 is welded to the bottom of the platform plate 112. It can be set at the corners of each edge of the platform plate 112, or at the bottom position corresponding to the middle of the platform plate 112. In an optional embodiment, the platform foundation 110 also includes a staircase 115. The staircase 115 adopts a gridded ladder structure. The bottom end of the staircase 115 is fixed to the ground, and the top end of the staircase 115 is connected to the edge of the platform plate 112, providing a passage for operators to go up and down the platform foundation 110.

[0039] The working process of using the tilting machine folding platform 100 of the present application to perform hot repair of the ladle is as follows: before the hot repair operation of the ladle from the ladle seat to the ladle tilting machine, operate the hydraulic system, drive the driver 122 to open the tilting machine folding plate 113, and after confirming safety, perform the hot repair operation of the ladle on the operating platform. After the operation is completed, close the folding plate 113 by operating the hydraulic system. The use of the present application ensures the safety of the hot repair operation of the ladle and improves the production efficiency. In addition, the present application has strong scalability, the material selection price is low, the overall structure is simple, and it is easy to make. In addition, the number of operators in the operation process during construction is small, the work efficiency is high, and the material and labor costs are saved.
