Description

Technical Field

[0001] This invention relates to the field of transformer manufacturing technology, and in particular to an auxiliary installation device for transformer manufacturing and its working method. Background Technology

[0002] A transformer is a static electrical device that uses the principle of electromagnetic induction to convert alternating current of a certain voltage level into alternating current of another voltage level at the same frequency. It is a core basic component for power transmission, distribution and power supply of electronic equipment. Oil-immersed transformers are power transformers in which the iron core and windings are completely immersed in insulating oil, relying on transformer oil as both an insulating medium and a cooling medium. They are the most widely used and technologically mature mainstream models in power systems.

[0003] Existing auxiliary installation equipment has certain defects in the process of assisting in the installation of oil-immersed transformers. For example, some oil-immersed transformers are composed of an outer shell, a top sealing plate, internal components, and external components. Workers will first assemble the top sealing plate, internal components, and external components into a combined assembly, and then use auxiliary installation equipment to hoist the assembled assembly onto the outer shell. During the hoisting and moving process, the assembly is prone to pendulum-like swaying, which affects the docking and installation between the outer shell and the assembly. Summary of the Invention

[0004] This invention provides an auxiliary installation device for transformer manufacturing and its working method, which can solve the problem in the prior art where the assembly consisting of the upper sealing plate, internal components and external components is prone to pendulum-like swaying during hoisting and moving, affecting the docking and installation of the outer shell and the assembly.

[0005] An auxiliary installation device for transformer manufacturing includes a frame, with a first conveying mechanism and a second conveying mechanism arranged below the frame. Both the first and second conveying mechanisms are equipped with positioning components. A lifting seat is movably mounted on the frame, with two pairs of lifting ropes symmetrically arranged on the lifting seat. A hook is fixed to the lower end of each rope. Two anti-sway mechanisms are symmetrically arranged on the lifting seat. Two winding components that cooperate with adjacent lifting ropes are provided on the lifting seat. A drive unit that cooperates with the frame is provided on the lifting seat.

[0006] As a further technical solution of the present invention, each of the anti-sway mechanisms includes two lifting rods that move through the hoisting base. Each lifting rod has a contact plate 1 fixed on its lower end surface. Each contact plate 1 has an anti-slip layer fixed on its lower end surface. Each contact plate 1 has a positioning component 2 on one side. The hoisting base is provided with two limiting components that cooperate with the corresponding lifting rods. Each contact plate 1 has a hoisting connecting lug 2 fixed on it.

[0007] As a further technical solution of the present invention, each of the positioning components II includes a connecting plate I fixed to one side of the upper end face of the contact plate I. A spring telescopic rod is fixedly disposed through the connecting plate I. A pressure sensor is fixed to the lower end of the spring telescopic rod. The lower end of the pressure sensor is fixed to the contact plate II. An indicator light is fixed to the upper end face of each connecting plate I.

[0008] As a further technical solution of the present invention, each of the winding components includes two pairs of mounting blocks I fixed to the upper end face of the lifting base, and a winding cylinder is rotatably arranged between each pair of mounting blocks I. One end of each lifting rope is fixed to the inner wall of the corresponding winding cylinder. A drive box I for cooperating with the rotation of the winding cylinder is fixed to the upper end face of the lifting base, and the same mounting block II is fixed to the upper end face of adjacent mounting blocks I.

[0009] As a further technical solution of the present invention, each of the limiting components includes two translation blocks movably disposed on the upper surface of the hoisting base. Each translation block has a detachable abutment layer on the side near the lifting rod. Each mounting block is provided with a drive unit 2 for use with the translation block. The hoisting base is provided with a guide unit for use with the translation block.

[0010] As a further technical solution of the present invention, each of the driving units includes a connecting plate two fixed to the upper end face of the mounting block two. A hydraulic rod is fixedly and through the connecting plate two. A U-shaped seat is fixed to the end of the extension end of the hydraulic rod. Two abutting wheels are symmetrically and rotatably arranged on the inner wall of the U-shaped seat. A guide slope is provided on one side of the upper end face of each translation block.

[0011] As a further technical solution of the present invention, each of the guide units includes a limiting groove formed on the upper end face of the hoisting base, and a limiting slider is slidably arranged in each limiting groove. A tension spring is fixed between the side of the limiting slider away from the lifting rod and the limiting groove.

[0012] As a further technical solution of the present invention, the first drive unit includes drive wheels rotatably disposed on both sides of the hoisting base, the second drive box is provided on the hoisting base for cooperating with the rotation of multiple drive wheels, and the upright is provided with a moving groove for cooperating with the drive wheels.

[0013] As a further technical solution of the present invention, each of the positioning components includes two fixed seats, and a positioning plate is rotatably provided on one side of each fixed seat. A drive box is provided on the fixed seat to cooperate with the positioning plate.

[0014] A method for operating an auxiliary installation device for transformer manufacturing, comprising the following specific steps: Step 1: Transport the assembly and the outer shell to directly below the support frame; Step two: First, the hoisting seat is moved directly above the assembly. Then, the hoisting rope is released by winding the assembly. The worker hangs the hook at the end of the hoisting rope onto the corresponding hoisting connection lug one, and then makes the anti-sway mechanism contact the upper sealing plate. Step 3: Next, wind the hoisting rope around the winding assembly. After hoisting the assembly to an appropriate height, the hoisting base will move the assembly to directly above the outer shell. Step four: Release the suspension ropes again from the winding assembly, causing the assembly to move downwards until the upper end face of the outer shell is in contact with the lower end face of the upper sealing plate.

[0015] The beneficial effects of this invention are: 1. When using the solution described in this application, when the assembly and the outer shell are transported to the underside of the support frame, the hoisting base first moves to the top of the assembly, then the winding assembly releases the hoisting rope. The worker hooks the hook at the end of the hoisting rope onto the corresponding hoisting connection lug, and then the anti-sway mechanism contacts the upper sealing plate. Next, the winding assembly winds the hoisting rope, lifting the assembly to an appropriate height. The hoisting base then moves the assembly to the top of the outer shell, and the winding assembly releases the hoisting rope again, causing the assembly to move downwards until the upper surface of the outer shell is aligned with the lower surface of the upper sealing plate. During this process, the anti-sway mechanism prevents the assembly from swaying during hoisting, thus facilitating the docking and installation of the assembly and the outer shell.

[0016] 2. In the initial state, the hook at the end of the lifting rope is hooked onto the corresponding lifting connection lug 2. On the one hand, the cooperation between the hook and the lifting rope can drive the contact plate 1 and the lifting rod to move up and down. On the other hand, it can limit the hook at the end of the lifting rope to prevent the hook from swinging randomly during the lifting process and colliding with the external components located on the upper surface of the upper sealing plate.

[0017] 3. During use, when the lifting platform is moved horizontally to directly above the assembly for lifting operations, first release the lifting ropes to cause the hook, lifting connecting lug 2, contact plate 1, and lifting rod to move downwards together. Under normal circumstances, the four contact plates 2 will move downwards to the side of the upper sealing plate, cooperating with the contact plate 1 to limit the position of the assembly. If there is a slight deviation between the position of the lifting platform and the assembly, some contact plates 2 may come into contact with the upper surface of the upper sealing plate, causing the pressure sensor to send an electrical signal, causing the indicator light at the corresponding position to light up, thus assisting the operator in fine-tuning the position of the lifting platform using the remote control. Similarly, when assembling the assembly and the outer shell, as contact plates 1 and 2 move downwards with the upper sealing plate, under normal circumstances, contact plates 2 will not come into contact with the upper surface of the outer shell. If an indicator light on one side lights up, it means that contact plate 2 at that position has touched the upper surface of the outer shell. Attached Figure Description

[0020] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0021] Reference Figures 1-15 An auxiliary installation device for transformer manufacturing includes a frame 1. A conveying mechanism 2 and a conveying mechanism 3 are arranged below the frame 1. Both the conveying mechanism 2 and the conveying mechanism 3 are equipped with positioning components. A lifting seat 4 is movably arranged on the frame 1. Two pairs of lifting ropes 5 are symmetrically arranged on the lifting seat 4. A hook 6 is fixed at the lower end of each lifting rope 5. Two anti-sway mechanisms are symmetrically arranged on the lifting seat 4. Two winding components that cooperate with adjacent lifting ropes 5 are arranged on the lifting seat 4. A drive unit 1 that cooperates with the frame 1 is arranged on the lifting seat 4.

[0022] This application is used to assist in the production and manufacturing of transformer body 50. Transformer body 50 is prior art. Transformer body 50 includes outer shell 51, upper sealing plate 52, internal component 53 and external component 54. Internal component 53 is fixed to the lower end face of upper sealing plate 52, and external component 54 is fixed to the upper end face of upper sealing plate 52. Four hoisting connecting lugs 55 are also fixed to the upper end face of upper sealing plate 52. Upper sealing plate 52, internal component 53 and external component 54 constitute assembly 56.

[0023] The conveying mechanism 2 is used to convey the assembly 56 consisting of the upper sealing plate 52, the internal component 53 and the external component 54. The conveying mechanism 2 is prior art.

[0024] The second conveyor 3 is used to convey the outer casing 51, and the second conveyor 3 is also existing technology.

[0025] When this solution is used, when the assembly 56 and the outer shell 51 are transported to the underside of the support frame 1, the lifting base 4 first moves to the top of the assembly 56, and then the winding assembly releases the lifting rope 5. The operator hooks the hook 6 at the end of the lifting rope 5 onto the corresponding lifting connection lug 55, and then the anti-sway mechanism contacts the upper sealing plate 52. Next, the winding assembly winds the lifting rope 5, lifting the assembly 56 to an appropriate height. The lifting base 4 then moves the assembly 56 to the top of the outer shell 51, and then the winding assembly releases the lifting rope 5 again, causing the assembly 56 to move downward until the upper end face of the outer shell 51 is in contact with the lower end face of the upper sealing plate 52. During this process, the anti-sway mechanism can prevent the assembly 56 from swaying during the lifting process, thus facilitating the docking and installation of the assembly 56 and the outer shell 51.

[0026] Each anti-sway mechanism includes two movable lifting rods 7 that pass through the hoisting base 4. Each lifting rod 7 has a contact plate 8 fixed to its lower end face. Each contact plate 8 has an anti-slip layer 9 fixed to its lower end face. Each contact plate 8 has a positioning component 2 on one side. The hoisting base 4 has two limiting components that cooperate with the corresponding lifting rods 7. Each contact plate 8 has a hoisting connecting lug 2 10 fixed to it.

[0027] In the initial state, the hook 6 at the end of the lifting rope 5 is hooked onto the corresponding lifting connection lug 2 10. On the one hand, the hook 6 and the lifting rope 5 work together to drive the contact plate 1 8 and the lifting rod 7 to move up and down. On the other hand, the hook 6 at the end of the lifting rope 5 can be limited to prevent the hook 6 from swinging randomly during the lifting process and colliding with the external component 54 located on the upper end face of the upper sealing plate 52.

[0028] When assembly 56 is transported directly below the support frame 1, the lifting base 4 first moves to directly above assembly 56, then releases the lifting rope 5, causing the hook 6 to move downwards along with the second lifting connecting lug 10, the first contact plate 8, and the lifting rod 7, until the anti-slip layer 9 on the lower end face of the first contact plate 8 contacts the upper end face of the upper sealing plate 52. During this process, the positioning component 2, in conjunction with the corresponding first contact plate 8, positions assembly 56. Then, the operator hooks the hook 6 onto the first lifting connecting lug 55. At this point, the first contact plate 8, under its own weight and the weight of the lifting rod 7, presses against the upper end face of the upper sealing plate 52. When the lifting rope 5, together with the hook 6, moves the assembly 56 upward, it also moves the positioning component 2, the contact plate 8, and the lifting rod 7 upward together. Then, the lifting seat 4 moves the assembly 56 horizontally to directly above the outer shell 51. During this process, the lifted assembly 56 is more prone to swaying (pendulum-like swaying) due to inertia. Therefore, when the lifting seat 4 moves the assembly 56 horizontally, the limiting component limits and fixes the lifting rod 7, causing the anti-slip layer 9 on the lower end of the contact plate 8 to adhere to the upper end of the upper sealing plate 52, preventing the swaying assembly 56 from pushing the contact plate 8 and the lifting rod 7 upward.

[0029] Each positioning component 2 includes a connecting plate 11 fixed to one side of the upper surface of the contact plate 1 8. A spring telescopic rod 12 is fixedly and through the connecting plate 11. A pressure sensor 13 is fixed to the lower end of the spring telescopic rod 12. A contact plate 2 14 is fixed to the lower end of the pressure sensor 13. An indicator light 15 is fixed to the upper surface of each connecting plate 11. A controller for use with the pressure sensor 13 and the indicator light 15 is provided on the mounting base 4. The controller is existing technology.

[0030] Two guide rods are symmetrically fixed on the upper end of the contact plate 14, and the upper end of each guide rod moves through the connecting plate 11.

[0031] During operation, when the lifting base 4 is moved horizontally to directly above the assembly 56 in preparation for lifting, the lifting rope 5 is first released, causing the hook 6 to move downwards along with the lifting connecting lug 10, contact plate 8, and lifting rod 7. Under normal circumstances, the four contact plates 14 will move downwards to the side of the upper sealing plate 52, working with the contact plate 8 to limit the position of the assembly 56. If there is a slight deviation between the position of the lifting base 4 and the assembly 56, some contact plates 14 will contact the upper surface of the upper sealing plate 52. In this situation, the pressure sensor 13 sends an electrical signal, causing the indicator light 15 at the corresponding position to light up, thereby assisting the operator in fine-tuning the position of the hoisting seat 4 via remote control. Similarly, when assembling the assembly 56 and the outer shell 51, as the contact plate 1 8 and contact plate 2 14 move downwards along with the upper sealing plate 52, under normal circumstances, contact plate 2 14 will not contact the upper surface of the outer shell 51. If the indicator light 15 on one side lights up, it means that contact plate 2 14 at that position has touched the upper surface of the outer shell 51.

[0032] Each winding assembly includes two pairs of mounting blocks 16 fixed to the upper surface of the lifting base 4. A winding drum 17 is rotatably arranged between each pair of mounting blocks 16. One end of each lifting rope 5 is fixed to the inner wall of the corresponding winding drum 17. A drive box 18 for rotating the winding drum 17 is fixed to the upper surface of the lifting base 4. The same mounting block 19 is fixed to the upper surface of adjacent mounting blocks 16.

[0033] The drive box 18 is existing technology. The drive box 18 can cause the winding drum 17 to rotate in the forward or reverse direction to achieve the winding and release of the suspension rope 5. This part is existing technology.

[0034] Each limiting component includes two translation blocks 20 movably mounted on the upper surface of the lifting base 4. Each translation block 20 has a detachable contact layer 21 on the side near the lifting rod 7. Each mounting block 29 is equipped with a drive unit 2 for use with the translation block 20. The lifting base 4 is equipped with a guide unit for use with the translation block 20.

[0035] When it is necessary to limit and fix the lifting rod 7, the second drive unit, in conjunction with the guide unit, causes the translation block 20 to move towards the lifting rod 7 with the contact layer 21 until the contact layer 21 is tightly against the side wall of the lifting rod 7. Under the action of friction, the lifting rod 7 is limited and fixed.

[0036] Each drive unit 2 includes a connecting plate 22 fixed to the upper end face of the mounting block 2 19. A hydraulic rod 23 is fixedly and through each connecting plate 22. A U-shaped seat 24 is fixed to the end of the telescopic end of the hydraulic rod 23. Two abutting wheels 25 are symmetrically and rotatably arranged on the inner wall of the U-shaped seat 24. A guide slope 26 is provided on one side of the upper end face of each translation block 20.

[0037] When the telescopic end of the hydraulic rod 23 extends, it drives the U-shaped seat 24 and the abutment wheel 25 to move downward. The abutment wheel 25 acts on the surface of the guide slope 26, thereby causing the translation block 20 to move with the abutment layer 21 toward the direction close to the lifting rod 7.

[0038] Each guide unit includes a limiting slide groove 27 opened on the upper end face of the hoisting base 4. A limiting slider 28 is slidably arranged in each limiting slide groove 27. A tension spring 29 is fixed between the side of the limiting slider 28 away from the lifting rod 7 and the limiting slide groove 27.

[0039] When the translation block 20 moves toward the direction close to the lifting rod 7 with the contact layer 21, the tension spring 29 is stretched and deformed, storing elastic potential energy. When the extension end of the hydraulic rod 23 retracts, driving the U-shaped seat 24 and the contact wheel 25 to move upward, the translation block 20 with the contact layer 21 is reset under the action of the tension spring 29.

[0040] The first drive unit includes drive wheels 30 rotatably mounted on both sides of the hoisting base 4. The hoisting base 4 is provided with a second drive box 31 for cooperating with the rotation of multiple drive wheels 30. The upright frame 1 is provided with a moving groove 32 for cooperating with the drive wheels 30.

[0041] The second drive box 31 is existing technology. The second drive box 31 causes the drive wheel 30 to rotate, thereby driving the hoisting base 4 to move. The remote control of the translation of the hoisting base 4 is a conventional technical means in this field.

[0042] Each positioning component includes two fixed seats 34, and a positioning plate 35 is rotatably mounted on one side of each fixed seat 34. A drive box 3 is mounted on the fixed seat 34 to cooperate with the positioning plate 35.

[0043] The positioning plate 35 enables the assembly 56 and the outer shell 51 to be transported directly below the support frame 1, which is a conventional technique in this field.

[0044] A method for operating an auxiliary installation device for transformer manufacturing, comprising the following specific steps: Step 1: Transport the assembly 56 and the outer shell 51 directly below the support frame 1; Step 2: First, the hoisting seat 4 is moved directly above the assembly 56. Then, the hoisting rope 5 is released by winding the assembly. The worker hangs the hook 6 at the end of the hoisting rope 5 onto the corresponding hoisting connection lug 55, and then makes the anti-sway mechanism contact the upper sealing plate 52. Step 3: Next, the winding assembly winds the lifting rope 5, and after the assembly 56 is lifted to an appropriate height, the lifting base 4 moves the assembly 56 to directly above the outer shell 51. Step four: The winding assembly releases the suspension rope 5 again, causing the assembly 56 to move downwards until the upper end face of the outer shell 51 is in contact with the lower end face of the upper sealing plate 52.

[0045] When the present invention is in use, when the assembly 56 and the outer shell 51 are transported to the underside of the support frame 1, the lifting base 4 first moves to the top of the assembly 56, and then the winding assembly releases the lifting rope 5. The operator hangs the hook 6 at the end of the lifting rope 5 onto the corresponding lifting connection lug 55, and then makes the anti-sway mechanism contact the upper sealing plate 52. Then the winding assembly winds the lifting rope 5, and after the assembly 56 is lifted to an appropriate height, the lifting base 4 drives the assembly 56 to move to the top of the outer shell 51. Then the winding assembly releases the lifting rope 5 again, causing the assembly 56 to move downward until the upper end face of the outer shell 51 is in contact with the lower end face of the upper sealing plate 52. During this process, the anti-sway mechanism can prevent the assembly 56 from swaying during the lifting process, thereby facilitating the docking and installation of the assembly 56 and the outer shell 51. In the initial state, the hook 6 at the end of the lifting rope 5 is hooked on the corresponding lifting connection lug 2 10. On the one hand, the hook 6 and the lifting rope 5 work together to drive the contact plate 1 8 and the lifting rod 7 to move up and down. On the other hand, the hook 6 at the end of the lifting rope 5 can be limited to prevent the hook 6 from swinging randomly during the lifting process and colliding with the external component 54 located on the upper end face of the upper sealing plate 52. When assembly 56 is transported directly below the support frame 1, the lifting base 4 first moves to directly above assembly 56, then releases the lifting rope 5, causing the hook 6 to move downwards along with the second lifting connecting lug 10, the first contact plate 8, and the lifting rod 7, until the anti-slip layer 9 on the lower end face of the first contact plate 8 contacts the upper end face of the upper sealing plate 52. During this process, the positioning component 2, in conjunction with the corresponding first contact plate 8, positions assembly 56. Then, the operator hooks the hook 6 onto the first lifting connecting lug 55. At this point, the first contact plate 8, under its own weight and the weight of the lifting rod 7, presses against the upper end face of the upper sealing plate 52. When the lifting rope 5, together with the hook 6, moves the assembly 56 upward, it also moves the positioning component 2, the contact plate 8, and the lifting rod 7 upward together. Then, the lifting seat 4 moves the assembly 56 horizontally to directly above the outer shell 51. During this process, the lifted assembly 56 is more prone to swaying (pendulum-like swaying) due to inertia. Therefore, when the lifting seat 4 moves the assembly 56 horizontally, the limiting component limits and fixes the lifting rod 7, causing the anti-slip layer 9 on the lower end of the contact plate 8 to adhere to the upper end of the upper sealing plate 52, preventing the swaying assembly 56 from pushing the contact plate 8 and the lifting rod 7 upward. During operation, when the lifting base 4 is moved horizontally to directly above the assembly 56 in preparation for lifting, the lifting rope 5 is first released, causing the hook 6 to move downwards along with the lifting connecting lug 10, contact plate 8, and lifting rod 7. Under normal circumstances, the four contact plates 14 will move downwards to the side of the upper sealing plate 52, working with the contact plate 8 to limit the position of the assembly 56. If there is a slight deviation between the position of the lifting base 4 and the assembly 56, some contact plates 14 will contact the upper surface of the upper sealing plate 52. In this situation, the pressure sensor 13 sends an electrical signal, causing the indicator light 15 at the corresponding position to light up, thereby assisting the operator in fine-tuning the position of the hoisting seat 4 via remote control. Similarly, when assembling the assembly 56 and the outer shell 51, as the contact plate 1 8 and contact plate 2 14 move downwards along with the upper sealing plate 52, under normal circumstances, contact plate 2 14 will not contact the upper surface of the outer shell 51. If the indicator light 15 on one side lights up, it means that contact plate 2 14 at that position has touched the upper surface of the outer shell 51.

[0046] The above-disclosed embodiments are merely preferred embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
