Description

Technical Field

[0001] This application relates to the field of object transfer, and more particularly to a transformer transfer device. Background Technology

[0002] In power systems, transformers, as key equipment, undertake important functions such as voltage transformation, power distribution, and transmission. With the continuous development of the power industry, the demand for transformer installation, maintenance, and replacement is increasing. In related technologies, cranes or forklifts are typically used for transformer relocation. Cranes can lift transformers with their booms and move them to a designated location. Forklifts can lift transformers and move them within a certain range. Regarding the aforementioned technologies, the inventors believe that when using these methods to relocate transformers, precise positioning between the transformer and the relocation device is difficult, and the transformer is prone to tipping over during the relocation process. Utility Model Content

[0003] To address the problems of transformers being difficult to locate accurately and prone to tipping over during transport, this application provides a transformer transport device.

[0004] The transformer transfer device provided in this application adopts the following technical solution:

[0005] A transformer transfer device includes a mounting base comprising a rectangular chassis and multiple leveling legs disposed at the bottom of the rectangular chassis. The rectangular chassis has a through-hole penetrating its inner and outer surfaces, and a guide sleeve is disposed at the through-hole. A lifting mechanism includes a lifting column and a hydraulic cylinder for driving the lifting column to move up and down. The hydraulic cylinder is vertically fixed to the rectangular chassis, and its piston rod is drivenly connected to the lower end of the lifting column. The upper end of the lifting column is fitted inside the guide sleeve. A translation mechanism includes at least one set of cross roller guide rail pairs, with the guide rails of the cross roller guide rail pairs fixed to the upper end face of the lifting column. A locking mechanism includes multiple electromagnetic clamps mounted on a sliding platform of the cross roller guide rail pairs.

[0006] By adopting the above technical solution, the operator first places the transformer transfer device in the reserved slot of the transformer foundation, adjusts the leveling legs to make the rectangular chassis level, uses a crane to move the transformer above the transformer foundation, and then operates the translation mechanism to move the sliding platform of the cross roller guide pair and the locking mechanism on the sliding platform to a suitable position to prepare for receiving the transformer. Then, the hydraulic pump station is started, so that the piston rod of the hydraulic cylinder pushes the lifting column to rise steadily and vertically along the guide sleeve. The translation mechanism on the lifting column rises accordingly until it fully contacts the bottom of the transformer base and bears all or most of the weight of the transformer. The transformer is then detached from the crane, and the operation continues. The hydraulic cylinders are used to position the transformer base slightly higher than the anchor bolts on the transformer foundation. The translation mechanism is adjusted so that the mounting holes on the transformer base correspond one-to-one with the anchor bolts. Then, the hydraulic valves are slowly operated to return oil to the hydraulic cylinders, and the lifting column lowers the transformer smoothly and vertically. After the transformer is fully in place and all anchor bolts have passed through the corresponding mounting holes, the locking mechanism is activated. The electromagnetic clamps are energized and firmly attach the transformer base to the sliding platform of the translation mechanism. With the transformer securely locked by the electromagnetic clamps, the nuts of all anchor bolts are tightened to fix the transformer to the transformer foundation. This improves the problem of transformers being difficult to position accurately and prone to tipping over during transport.

[0007] Optionally, the number of leveling legs is four, and the upper ends of the four leveling legs are respectively arranged at the four corners of the rectangular chassis.

[0008] By adopting the above technical solution, the four leveling legs are arranged at the four corners of the rectangular chassis, which can better adapt to different ground conditions, making the mounting base more stably placed in the middle of the transformer foundation, thus enhancing the overall stability and leveling capability of the device.

[0009] Optionally, the piston rod of the hydraulic cylinder is connected to the lifting column by a thread.

[0010] By adopting the above technical solution, the connection between the piston rod of the hydraulic cylinder and the lifting column is made more stable through the use of threaded connection, which facilitates the installation and disassembly of the lifting column, and ensures the reliability of power transmission, thus ensuring the stable lifting of the lifting column.

[0011] Optionally, the cross roller guide pair includes a horizontally arranged reference guide and a slider assembly slidably arranged on the reference guide; the slider assembly includes two driven slide rails slidably arranged on both sides of the reference guide, a sliding platform mounted on the upper end of the two driven slide rails, a plurality of first rollers mounted on the side of the driven slide rails facing the reference guide, and a plurality of second rollers mounted on the side of the driven slide rails facing the reference guide and arranged intersecting with the first rollers; the first rollers and the second rollers are evenly spaced along the length direction of the reference guide, and the reference guide has a first groove for arranging the first rollers and a second groove for arranging the second rollers.

[0012] By adopting the above technical solution, the reference guide rail of the cross roller guide pair cooperates with the slider assembly, and the driven slide rail slides in the first and second slide grooves of the reference guide rail through the first and second rollers, so that the slider assembly drives the sliding platform to move smoothly, thereby realizing the translation function of the transformer transfer device; the special structure of the cross roller guide pair makes the sliding of the slider assembly on the reference guide rail more stable and smooth, reduces friction and jamming, and improves the translation accuracy and stability during the transformer transfer process.

[0013] Optionally, the number of the cross roller guide rail pairs is two sets, and the two sets of cross roller guide rail pairs are parallel to each other and symmetrically arranged on the upper end face of the lifting column by high-strength bolts.

[0014] By adopting the above technical solution, installing two sets of parallel cross roller guide rails symmetrically arranged on the upper end face of the lifting column by high-strength bolts helps to improve the stability and load-bearing capacity of the transformer transfer device during translation.

[0015] Optionally, the guide rail surface is provided with a scale.

[0016] By adopting the above technical solution, setting a scale on the guide rail surface makes it easier for operators to accurately control the position and movement distance of the transformer during the translation process, which helps to improve the precision and accuracy of transformer transfer.

[0017] Optionally, the electromagnetic clamp includes a mounting base and four electromagnetic units arranged on the surface of the mounting base, the four electromagnetic units being distributed in a cross shape on the surface of the mounting base; the surface of the mounting base is provided with four linear grooves for adjusting the sliding arrangement of each electromagnetic unit, and the bottom of each electromagnetic unit has a linear slider that cooperates with the corresponding linear groove.

[0018] By adopting the above technical solution, the four electromagnetic units of the electromagnetic clamp are distributed in a cross shape on the surface of the mounting base, and their positions can be adjusted by sliding the linear slider in the linear groove. This allows for flexible adaptation to transformers of different sizes and shapes, enhancing the clamp's fixing effect and applicability to transformers.

[0019] Optionally, the linear slider has a mounting hole at its bottom and a ball-head spring plunger is disposed in the mounting hole. The linear groove has multiple snap-fit ​​holes at its bottom for the ball-head spring plunger to snap into place. The multiple snap-fit ​​holes are evenly spaced along the length of the linear groove.

[0020] By adopting the above technical solution, a ball-head spring plunger is installed at the bottom of the linear slider and multiple locking holes are opened at the bottom of the linear slide groove. This allows the electromagnetic unit to slide in the linear slide groove and then be locked and fixed by the ball-head spring plunger and the locking holes. This enables flexible adjustment and reliable positioning of the electromagnetic unit, and facilitates the locking and fixing of transformers of different specifications by the transformer transfer device, thereby improving the applicability and transfer stability of the device.

[0021] Optionally, the number of electromagnetic clamps is two, and the two electromagnetic clamps are respectively arranged on the surfaces of the two sliding platforms.

[0022] By adopting the above technical solution, two electromagnetic clamps are respectively arranged on the surfaces of two sliding platforms, which can lock the transformer from two positions when transferring the transformer, which helps to enhance the fixing effect of the transformer and ensure the stability of the transformer during the transfer process.

[0023] Optionally, the guide sleeve is fixed to the rectangular chassis by welding.

[0024] By adopting the above technical solution, the rectangular base of the mounting base and the guide sleeve are fixed by welding, making the connection between the guide sleeve and the rectangular base more solid, ensuring the structural stability of the transfer device, and helping to improve the overall performance and service life of the device.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. A transformer transfer device, comprising a mounting base, a lifting mechanism, a translating mechanism, and a locking mechanism; when using the transformer transfer device to transfer a transformer, the operator first places the transformer transfer device in the reserved groove of the transformer foundation, adjusts the leveling legs to make the rectangular base level, uses a crane to move the transformer above the transformer foundation, then operates the translating mechanism to move the sliding platform of the cross roller guide pair and the locking mechanism on the sliding platform to the appropriate position, and then starts the hydraulic pump station until the translating mechanism fully contacts the bottom of the transformer base and supports all or most of the transformer. Partial weight was removed, and the transformer was detached from the crane. The hydraulic cylinder was operated to make the bottom of the transformer slightly higher than the anchor bolts on the transformer foundation. The translation mechanism was adjusted so that the mounting holes of the transformer base corresponded to the anchor bolts one by one. Then, the hydraulic valve was slowly operated to return oil to the hydraulic cylinder. After the transformer was fully positioned and all the anchor bolts had passed through the corresponding mounting holes, the locking mechanism was activated and the electromagnetic clamp was energized. With the transformer stably locked by the electromagnetic clamp, the nuts of all the anchor bolts were tightened to fix the transformer to the transformer foundation. This improved the problem of the transformer being difficult to position accurately and easy to tip over during the transfer.

[0027] 2. Through the cooperation of the reference guide rail and the slider assembly of the cross roller guide pair, the driven slide rail slides in the first and second grooves of the reference guide rail via the first and second rollers, so that the slider assembly drives the sliding platform to move smoothly, thereby realizing the translation function of the transformer transfer device; the special structure of the cross roller guide pair makes the sliding of the slider assembly on the reference guide rail more stable and smooth, reduces friction and jamming, and improves the translation accuracy and stability during the transformer transfer process;

[0028] 3. The four electromagnetic units of the electromagnetic clamp are arranged in a cross shape on the surface of the mounting base, and their positions can be adjusted by sliding the linear slider in the linear groove. This allows for flexible adaptation to transformers of different sizes and shapes, enhancing the clamp's fixing effect and applicability to transformers. Attached Figure Description
