Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, specifically a transformer transportation protection device. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Its main components are the primary coil, the secondary coil, and the iron core. Its main functions include voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization. After the transformer is manufactured and processed, it needs to be transported to a designated location for use.

[0003] Chinese patent provides a protective device for transformer transportation, publication number CN217970715U, which includes a tray, with columns fixedly connected to the top of both sides of the tray, and a top cover provided on the top of the tray. The top cover and the columns are installed by fixing bolts, and a pressing device is provided inside the top cover.

[0004] The above-mentioned device has columns installed on both sides of the top of the pallet for installing the top cover. The transformer to be transported is placed on the pallet and the corresponding position is adjusted. Then, the top cover and the columns are installed with fixing bolts to protect the transformer. The top cover is equipped with a compression device to facilitate compression of the top of the transformer and improve the stability of the transformer. The base and damping shock absorber are installed under the pallet to provide a certain buffering performance.

[0005] However, its structure is relatively simple. The transformer is fixed by a frame and multiple extrusion plates. The overall structure is relatively bulky and the protection effect is poor. At the same time, the process of transferring it to a transport vehicle is relatively difficult. When moving it short distances without the help of a transport vehicle, it needs to be carried directly by personnel, which is quite laborious. Utility Model Content

[0006] The purpose of this utility model is to provide a transformer transportation protection device that can effectively solve the problems in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A transformer transport protection device includes a protective shell one and a protective shell two.

The first protective shell is threadedly connected to the first protective shell through the threaded holes. A handle is slidably installed on the outer ring of the mounting bolt away from the first protective shell through a mounting sleeve. Rotary wheels are rotatably installed on the outer ring of the handle near both sides.

[0010] Preferably, a buffer spring is provided on the outer ring of the mounting bolt and on the side close to the protective shell, and the front and rear ends of the buffer spring abut against the front and rear opposing surfaces of the protective shell and the mounting sleeve, respectively.

[0011] Preferably, the bottom of the second protective shell is provided with a plurality of equally spaced annular dampers, and the top of the first protective shell is provided with lifting rings near the corners.

[0012] Preferably, a sliding rod is fixedly installed on both sides of the end of the extrusion plate away from the flexible airbag.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Combination Figures 1-4 A transformer transport protection device includes a protective shell 1 and a protective shell 2. The protective shell 1 is installed on the top of the protective shell 2 by fixing bolts. A compression threaded rod 3 is threaded through the top of the protective shell 1 near the front and rear ends. A compression threaded rod 4 is threaded through the front and rear ends of the protective shell 2 near the lower ends. A compression plate 5 is rotatably connected to one end of the compression threaded rod 3 and the compression threaded rod 4 that extends into the protective shell 1 and the protective shell 2, respectively.

[0026] See Figure 2 and Figure 4Furthermore, a flexible airbag 6 is provided at one end of the extrusion plate 5 near the center of the protective shell 1. A base plate 7 is slidably installed at the lower part of the interior of the protective shell 2. Several circular dampers 8 are provided below the base plate 7. A buffer rubber pad 9 is adhered to the top of the base plate 7. Slide rods are fixedly installed on both sides of the end of the extrusion plate 5 away from the flexible airbag 6. The end of the slide rod away from the extrusion plate 5 passes through the protective shell 1 and the protective shell 2, and the slide rod is slidably connected to the protective shell 1 and the protective shell 2.

[0027] Specifically, the transformer body to be transported can be placed inside the protective shell 2 as needed, and positioned between the two compression plates 5. Then, the compression threaded rod 4 on the protective shell 2 can be turned, thereby pushing the two flexible airbags 6 closer to the transformer. After moving to the appropriate position, appropriate gas can be injected into the flexible airbags 6 as needed, causing the flexible airbags 6 to inflate and press against the side of the transformer, so as to automatically adapt to the shape of the transformer and provide non-rigid clamping to reduce damage to the transformer shell. Afterwards, the protective shell 1 can be installed onto the protective shell 2 using fixing bolts to complete the sealing and protection of the transformer. Before sealing, the flexible airbags 6 on the compression threaded rod 3 can be inflated. Then, the compression threaded rod 3 can be turned, pushing the compression plates 5 and flexible airbags 6 connected to it to compress the top of the transformer, thereby limiting the upward movement distance of the transformer and improving the protection effect. At the same time, the circular damper 8, the base plate 7, and the buffer rubber pad 9 provide support for the bottom of the transformer, which can reduce vibration.

[0028] Example 2

[0029] See Figure 2 and Figure 3 Furthermore, based on Embodiment 1, the protective shell 1 has threaded holes 12 on both sides of its front and rear ends. A mounting bolt 16 is threadedly connected to the protective shell 1 through the threaded holes 12. A handle 13 is slidably mounted on the outer ring of the mounting bolt 16 away from the protective shell 1 via a mounting sleeve 15. A rotating wheel 14 is rotatably mounted on the outer ring of the handle 13 on both sides. A buffer spring 17 is provided on the outer ring of the mounting bolt 16 and near the protective shell 1. The front and rear ends of the buffer spring 17 are respectively connected to the protective shell 1... The front and rear surfaces of the protective shell 1 and the mounting sleeve 15 abut against each other. The bottom end of the protective shell 2 is provided with several equally spaced circular dampers 8. The top corner of the protective shell 1 is provided with lifting rings 11. The lower front and rear ends of the protective shell 2 are provided with mounting plates 18. The upper and lower ends of the mounting plate 18 are provided with mounting holes that are compatible with the mounting bolts 16. The outer ring of the handle 13 is fitted with a directional rubber sleeve. When the buffer spring 17 is under extreme compression, the outer ring of the wheel 14 extends beyond the mounting bolt 16 and is close to the end of the mounting sleeve 15.

[0030] Specifically, the protrusions 10 and lifting rings 11 facilitate the transport of protective shell 1 and protective shell 2 using external transportation equipment such as forklifts or cranes. The handles 13 provide a grip, allowing for easy handling in small spaces where vehicles cannot easily access. The outer ring of the handles 13 is equipped with rotating wheels 14. The handles 13 are mounted on protective shell 1 via mounting bolts 16 and threaded holes 12. The mounting plate 18 on protective shell 2 has mounting holes that align with the mounting bolts 16, thus enabling easy transport. The handle 13 can be installed on the mounting plate 18 as needed, and the roller 14 can be positioned below the mounting plate 18. The roller 14 provides support for pushing and transporting the equipment. During the contact between the roller 14 and the bottom surface, the mounting sleeve 15 will move upward under the force and compress the buffer spring 17. The buffer spring 17 will buffer the impact. At the same time, during pushing and transporting, the buffer spring 17, the circular damper 8, and the buffer rubber pad 9 can work together to provide shock absorption and protection for the transformer inside the protective shell 2, preventing vibration from being directly transmitted to the transformer.

[0031] In actual operation, the transformer body to be transported can be placed inside the second protective shell 2 as needed, and positioned between the two extrusion plates 5. Then, the extrusion threaded rod 4 on the second protective shell 2 can be turned, thereby pushing the two flexible airbags 6 toward the transformer. After moving to the appropriate position, appropriate gas can be injected into the flexible airbags 6 as needed, so that the flexible airbags 6 inflate and press against the side of the transformer, so as to automatically adapt to the shape of the transformer and provide non-rigid clamping to reduce damage to the transformer shell. Afterwards, the first protective shell 1 can be installed on the second protective shell 2 by fixing bolts to complete the sealing and protection of the transformer.

[0032] Before sealing, the flexible airbag 6 on the extrusion threaded rod 3 can be inflated. Then, the extrusion threaded rod 3 can be turned, and the thread will push the extrusion plate 5 and the flexible airbag 6 connected to it to extrude the top of the transformer to limit the upward movement of the transformer and improve the protection effect. At the same time, the bottom of the transformer is supported by the set annular damper 8, the base plate 7, and the buffer rubber pad 9, which can reduce vibration.

[0033] The protrusions 10 and lifting rings 11 are provided to facilitate the transport of protective shell 1 and protective shell 2 by external transportation equipment such as forklifts or cranes. At the same time, the handles 13 provide a gripping function, allowing personnel to exert force to move the protective shells in small areas where vehicles cannot easily access them.

[0034] Meanwhile, the outer ring of the handle 13 is rotatably mounted with a wheel 14, and the handle 13 is mounted on the protective shell 1 through the mounting bolt 16 and the mounting thread hole 12. The mounting plate 18 on the protective shell 2 has a mounting hole that is compatible with the mounting bolt 16. Thus, during transportation, the handle 13 can be mounted on the mounting plate 18 as needed, and the wheel 14 can be positioned below the mounting plate 18. At this time, the wheel 14 can provide support so that personnel can push and transport it.

[0035] Furthermore, during the process of the rotating wheel 14 contacting the ground, the mounting sleeve 15 will move upward under the force and squeeze the buffer spring 17. The buffer spring 17 will play a buffering role against the impact. During the push, the buffer spring 17, the circular damper 8 and the buffer rubber pad 9 work together to provide shock absorption and protection for the transformer inside the protective shell 2, preventing the vibration from being directly transmitted to the transformer.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
