Description

Technical Field

[0001] This invention belongs to the field of power equipment technology, and in particular to a transfer device for power transformers. Background Technology

[0002] In the construction and operation of power engineering projects, power transformers, as core equipment for power conversion and transmission, directly affect the project progress and construction quality through the convenience and safety of their transportation and installation. Power transformers are typically large and heavy, requiring specialized transportation equipment for relocation during process flow within the production workshop, handling on the construction site, and final installation and positioning.

[0003] Currently, there are various types of transfer equipment used for power transformers, commonly including transfer trolleys, roller frames, and forklift adapters. However, these existing transfer devices generally suffer from a key technical deficiency: they lack height adjustment capabilities, meaning they cannot raise the transformer's placement height according to actual operational needs. In actual installation or handling scenarios, this deficiency causes numerous problems: for example, when installing a transformer onto a pre-set mounting base, bracket, or connecting it to other electrical equipment, the existing transfer equipment cannot directly lift the transformer to the corresponding height due to the height difference between the mounting reference surface and the load-bearing surface of the transfer equipment. Manual adjustment using simple tools such as crowbars and jacks is required. Similarly, when transferring transformers between conveyor lines at different heights within a workshop, existing transfer equipment cannot match the conveyor line height, again necessitating manual assistance to raise the transformer for material handover.

[0004] The aforementioned manual lifting method is not only labor-intensive, consuming significant manpower and time costs and reducing the efficiency of transportation and installation, but also poses significant safety hazards. Due to the large weight of transformers, uneven force distribution and operational errors during manual lifting can easily cause the transformer to tilt or slip, leading to equipment damage and even personal injury. Therefore, addressing the problem of existing power transformer transportation equipment being unable to raise the transformer and relying on manual lifting, there is an urgent need to develop a transportation device with height adjustment capabilities. This would solve the shortcomings of existing technologies, such as low efficiency, significant safety hazards, and poor assembly precision, and meet the high-efficiency and safe requirements of the power engineering field for transformer transportation and installation operations. Summary of the Invention

[0005] The purpose of this invention is to overcome the defects in the prior art and provide a transfer device for power transformers that can solve the above-mentioned problems in the prior art.

[0006] A transfer device for power transformers, comprising: The support assembly includes a support plate; A lifting assembly, the top of which is connected to the bottom of the supporting assembly, to drive the supporting assembly to move up and down; A movable base is disposed below the lifting assembly and connected to the lifting assembly via a drive assembly, which can drive the lifting assembly to move horizontally.

[0007] Furthermore, guide grooves are symmetrically arranged on both sides of the top of the mobile base; four omnidirectional wheels are fitted to the bottom of the mobile base.

[0008] Furthermore, the lifting assembly includes a movable frame, a lifting guide frame, and a cylinder. The movable frame is a cuboid frame structure. The bottom of the movable frame is provided with movable wheels and guide wheels. The guide wheels are installed at the bottom of one end of the movable frame and can move along the guide groove at the top of the movable base. The movable wheels are installed at the other end of the movable frame and are on the same horizontal line as the casters. The four lifting guide frames are symmetrically installed in pairs on both sides of the movable frame. The lifting guide frames are provided with elongated guide holes. The bearing plate is provided with four guide columns whose positions and sizes are adapted to the elongated guide holes. The guide columns are inserted through the elongated guide holes and can move along the elongated guide holes. The cylinder drive end is hinged to the bottom of the support plate, and the cylinder fixed end is hinged to the movable frame.

[0009] Furthermore, the drive assembly includes a threaded rod and a turntable. The two ends of the threaded rod are rotatably connected to the movable base, and the end of the threaded rod away from the lifting assembly passes through the movable base and is connected to the turntable. One end of the movable frame is installed on the threaded rod through a threaded connection, and the movable frame moves by rotating the threaded rod.

[0010] Furthermore, the lifting guide frame and the moving frame form a right-angled triangle structure, and the elongated guide hole is located on the inclined end side of the lifting guide frame.

[0011] Furthermore, it also includes a handrail, which is fixedly connected to one end of the movable base for the operator to hold and push the transfer device to move.

[0012] Furthermore, the support plate is a rectangular plate structure, and baffles are provided at the front and rear ends and near the handrail of the support plate. The baffles are used to limit the displacement of the power transformer on the support plate.

[0013] Furthermore, the upper surface of the support plate is provided with several anti-slip protrusions.

[0014] The advantages and beneficial effects of this invention are as follows: (1) The operator rotates the turntable, which drives the threaded rod to rotate. Since one end of the moving frame is threadedly connected to the threaded rod, the rotation of the threaded rod will be converted into the horizontal displacement of the moving frame. At the same time, the guide wheel at the bottom of the moving frame slides along the guide groove of the moving base and the moving wheel moves synchronously with the moving frame to ensure that the moving frame slides stably in the horizontal direction, thereby adjusting the horizontal position of the bearing plate and the power transformer to adapt to different transfer or installation docking points.

[0015] (2) When the cylinder pushes the bearing plate, the guide column at the bottom of the bearing plate 1 will move along the long guide hole on the inclined side of the lifting guide frame. Since the lifting guide frame and the moving frame form a right triangle structure, the long guide hole is arranged at an inclination. The movement of the guide column will simultaneously drive the bearing plate to rise or fall in the inclination direction, and finally realize the vertical height adjustment of the bearing plate 1, thereby replacing the traditional manual lifting.

[0016] (3) The lifting guide frame and the moving frame form a right-angled triangle structure, which utilizes the stability of the triangle to improve the load-bearing strength during the lifting process; the cuboid frame of the moving frame, together with the moving wheels and guide wheels, ensures the structural rigidity during horizontal movement.

[0017] (4) The baffle of the bearing plate restricts the horizontal sliding of the power transformer, and the anti-slip protrusion increases the friction to prevent the power transformer from slipping during transportation or lifting.

[0018] (5) The device of the present invention first adjusts the horizontal position of the lifting component by means of the threaded rod, and then pushes the bearing plate by means of the cylinder, and realizes the height lifting by means of the trajectory of the inclined long strip guide hole. At the same time, it is combined with baffles and casters to complete the efficient transportation and manual lifting installation of the power transformer. Attached Figure Description

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] like Figure 1-4 As shown, a transfer device for a power transformer includes... The support assembly includes a support plate 1; A lifting assembly, the top of which is connected to the bottom of the supporting assembly, to drive the supporting assembly to move up and down; The movable base 2 is disposed below the lifting component and is connected to the lifting component through a drive component, and the lifting component can be driven to move horizontally through the drive component.

[0023] As a preferred embodiment of the above technical solution, guide grooves 3 are symmetrically arranged on both sides of the top of the mobile base 2; four universal wheels 11 are assembled at the bottom of the mobile base 2.

[0024] As a preferred embodiment of the above technical solution, the lifting assembly includes a movable frame 4, a lifting guide frame 5, and a cylinder 6. The movable frame 4 is a cuboid frame structure. The bottom of the movable frame 4 is provided with a movable wheel 7 and a guide wheel 8. The guide wheel 8 is installed at the bottom of one end of the movable frame 4 and can move along the guide groove 3 at the top of the movable base 2. The movable wheel 7 is installed at the other end of the movable frame 4 and is on the same horizontal line as the universal wheel 11. The four lifting guide frames 5 are symmetrically installed in pairs on both sides of the movable frame 4. The lifting guide frame 5 is provided with a long strip guide hole 9. The bearing plate 1 is provided with four guide columns 10 whose positions and sizes are adapted to the long strip guide hole 9. The guide columns 10 are inserted through the long strip guide hole 9 and can move along the long strip guide hole 9. The driving end of the cylinder 6 is hinged to the bottom of the bearing plate 1, and the fixed end of the cylinder 6 is hinged to the movable frame 4.

[0025] In the above technical solution, when the driving end of the cylinder 6 pushes the bearing plate 1, the guide column 10 at the bottom of the bearing plate 1 will move along the elongated guide hole 9 on the inclined side of the lifting guide frame 5. Since the lifting guide frame 5 and the moving frame 4 form a right-angled triangle structure, the elongated guide hole 9 is arranged at an angle. The movement of the guide column 10 will simultaneously drive the bearing plate 1 to rise or fall in the inclined direction, and finally realize the vertical height adjustment of the bearing plate 1, thereby replacing the traditional manual lifting.

[0026] As a preferred embodiment of the above technical solution, the drive assembly includes a threaded rod 12 and a turntable 13. The two ends of the threaded rod 12 are rotatably connected to the movable base 2, and the end of the threaded rod 12 away from the lifting assembly passes through the movable base 2 and is connected to the turntable 13. One end of the movable frame 4 is installed on the threaded rod 12 by a threaded connection, and the movable frame 4 moves by rotating the threaded rod 12.

[0027] In the above technical solution, the operator rotates the turntable 13, which drives the threaded rod 12 to rotate. Since one end of the moving frame 4 is threadedly connected to the threaded rod 12, the rotation of the threaded rod will be converted into the horizontal displacement of the moving frame 4. At the same time, the guide wheel 8 at the bottom of the moving frame 4 slides along the guide groove 3 of the moving base 2, and the moving wheel 7 moves synchronously with the moving frame 4 to ensure that the moving frame slides stably in the horizontal direction, thereby adjusting the horizontal position of the bearing plate and the power transformer to adapt to different transfer or installation docking points.

[0028] As a preferred embodiment of the above technical solution, the lifting guide frame 5 and the movable frame 4 form a right-angled triangular structure, and the elongated guide hole 9 is located on the inclined end side of the lifting guide frame 5. The right-angled triangular structure between the lifting guide frame 5 and the movable frame 4 utilizes the stability of the triangle to improve the load-bearing capacity during the lifting process.

[0029] As a preferred embodiment of the above technical solution, it further includes a handrail 14, which is fixedly connected to one end of the movable base 2 and is used for the operator to hold and push the transfer device to move.

[0030] As a preferred embodiment of the above technical solution, the bearing plate 1 is a rectangular plate structure, and baffles 15 are provided at the front and rear ends and near the handrail of the bearing plate 1. The baffles 15 are used to limit the displacement of the power transformer on the bearing plate.

[0031] As a preferred embodiment of the above technical solution, the upper surface of the bearing plate 1 is provided with a number of anti-slip protrusions.

[0032] In the above technical solution, the baffle 15 of the bearing plate restricts the horizontal sliding of the power transformer, and the anti-slip protrusions increase the friction to prevent the power transformer from slipping during transportation or lifting.

[0033] The working principle of this invention is as follows: The operator rotates the turntable 13, causing the threaded rod 12 to rotate. Since one end of the moving frame 4 is threadedly connected to the threaded rod 12, the rotation of the threaded rod is converted into the horizontal displacement of the moving frame 4. At the same time, the guide wheel 8 at the bottom of the moving frame 4 slides along the guide groove 3 of the moving base 2, and the moving wheel 7 moves synchronously with the moving frame 4, ensuring that the moving frame slides stably in the horizontal direction, thereby adjusting the horizontal position of the bearing plate and the power transformer to adapt to different transfer or installation docking points.

[0034] When the driving end of the cylinder 6 pushes the support plate 1, the guide column 10 at the bottom of the support plate 1 will move along the elongated guide hole 9 on the inclined side of the lifting guide frame 5. Since the lifting guide frame 5 and the moving frame 4 form a right-angled triangle structure, the elongated guide hole 9 is arranged at an angle. The movement of the guide column 10 will simultaneously drive the support plate 1 to rise or fall in the inclined direction, thus realizing the vertical height adjustment of the support plate 1, thereby replacing the traditional manual lifting.

[0035] The casters 11 of the movable base 2 enable flexible transportation of the entire device, and the locking function can fix the position of the device. The baffle 15 of the bearing plate restricts the horizontal sliding of the power transformer, and the anti-slip protrusions increase the friction to prevent the power transformer from slipping during transportation or lifting. The lifting guide frame 5 and the moving frame 4 form a right-angled triangle structure, which utilizes the stability of the triangle to improve the load-bearing strength during the lifting process; the cuboid frame of the moving frame 4, together with the moving wheels and guide wheels, ensures the structural rigidity during horizontal movement.

[0036] The device first adjusts the horizontal position of the lifting assembly through a threaded rod, then pushes the bearing plate through a cylinder, and uses the trajectory of the inclined elongated guide hole to achieve height lifting. At the same time, it works with baffles and casters to complete the efficient transportation and manual lifting installation of power transformers.

[0037] It should be emphasized that the embodiments described in this invention are illustrative rather than limiting. Therefore, this invention includes, but is not limited to, the embodiments described in the specific implementation. Any other implementations derived by those skilled in the art based on the technical solutions of this invention are also within the scope of protection of this invention.
