Description

Technical Field

[0001] The utility model relates to the technical field of dry-type transformers, in particular to a mounting bracket and a dry-type transformer. Background Art

[0002] Dry-type transformers are widely used in places like local lighting, high-rise buildings, airports, and CNC machinery at ports. Simply put, a dry-type transformer is one whose core and windings are not immersed in insulating oil. Dry-type transformers typically require a mounting bracket during installation. Existing mounting brackets are connected to the dry-type transformer using bolts, making them difficult to install.

[0003] The technical solution disclosed in the Chinese patent with the authorization announcement number CN219832353U is achieved by symmetrically setting two guide holes on the mounting plate, and setting a rack at the bottom of the guide hole. The movable seat is slidably set on the mounting plate, and the movable plate is symmetrically and elastically slidably set on the movable seat, and vertical rods are symmetrically set at the bottom of the movable plate. The vertical rods on both sides are respectively inserted into the corresponding side guide holes, and a clamping block is set at the bottom of the vertical rod, and the clamping block is engaged with the rack. The splint is symmetrically and slidably set on the movable seat, and a slider A is slidably set on the splint. A screw threadedly connected to the slider A is set on the inner side of the slider A, and a pressure plate is sleeved on the screw. The bidirectional screw is rotatably set in the slide groove B, and the bidirectional screw drives and connects the two sliders B. The slider B is driven and connected to the corresponding side splint through a connecting rod. This makes the device suitable for the installation of power transformers of different sizes, and the position of the transformer can be fine-tuned after installation.

[0004] However, this device still has some shortcomings: the transformer will generate vibrations during operation, and these vibrations are mainly transmitted to the building structure through the base, thereby affecting the surrounding environment. The device lacks a shock-absorbing and vibration-absorbing structure, and the slider A in the device is in a sliding state. When the transformer is working and vibrating, it is easy to slide sideways on the movable seat. Utility Model Content

DETAILED DESCRIPTION

[0025] Example 1

[0026] like Figure 1-Figure 3As shown, the utility model proposes a mounting bracket, including a base 1, a slide 5, a slide 6, a sliding limit assembly and a driving assembly 7. An inner cavity 101 is set in the base 1, and a buffer assembly is set in the inner cavity 101. The buffer assembly includes a spring rod 4, the lower end of the spring rod 4 is connected to the lower wall of the inner cavity 101, and the upper end of the spring rod 4 is connected to the bottom of the slide 5. The bottom of the slide 5 is inserted into the inner cavity 101 and is slidably connected to its inner wall, and the bottom of the slide 5 is connected to the buffer assembly. Two groups of slides 6 are symmetrically arranged on the slide 5 and are slidably connected thereto, and two sliders 8 are symmetrically arranged on the slide 6, and the sliders 8 are connected to the movable connecting parts. A limiting groove 501 is set in the slide 5, the slide 6 is located in the slide groove and is slidably connected thereto, and the top of the slide 6 exceeds the upper surface of the slide 5. A plurality of support rollers 502 rotatably connected to the slide 5 are provided between the limiting grooves 501 on both sides. The top ends of the support rollers 502 are located above the upper surface of the slide 5. The support rollers 502 preferentially contact the transformer on either side of the clamping plates to facilitate the sliding of the transformer. The movable connecting parts include a pressure plate 9 and a screw 11. A groove is provided at the bottom of the slider 8. The pressure plate 9 is located inside the groove and is slidably connected to its inner wall. A latch 10 is provided at the bottom of the pressure plate 9. The screw 11 is spirally connected to the slider 8. The screw 11 passes through the pressure plate 9 and is inserted into the latch 10. The screw 11 is spirally connected to the pressure plate 9 and the latch 10. The slip limiting assembly includes a rack 12 and a gear 13. The carriage 6 is provided with a chute 601, into which the slider 8 is inserted and slidably connected. Two racks 12 are staggered within the chute 601 and slidably connected to the inner wall of the chute 601. The ends of the racks 12 on either side, facing away from each other, are respectively connected to the slider 8 on the corresponding side. A gear 13 is positioned within the chute 601 and rotationally connected to the carriage 6. The gear 13 is positioned between the racks 12 and meshes with both racks 12. A drive assembly 7 is connected to the carriage 5 and drives the carriages 6 on both sides, thereby adjusting the spacing between the carriages 6 via the drive assembly 7.

[0027] The present invention also provides a dry-type transformer having the aforementioned mounting bracket, further comprising a transformer housing 14. Two sets of mounting holes are symmetrically arranged on the bottom of the transformer housing 14, each set of two mounting holes. The transformer housing 14 is positioned on a slide 5, with latches 10 on either side inserted into the mounting holes on the corresponding sides. A transformer body 15 is disposed within the transformer housing 14. Furthermore, the transformer housing 14 is provided with an air intake and an air exhaust hole communicating therewith. A dust screen is disposed within the air intake hole, and a heat sink 16 is disposed within the air exhaust hole.

[0028] In this embodiment, the transformer housing 14 is placed longitudinally and centered on the slide 5. The drive assembly drives the two side slides 6 toward each other and respectively abuts the two sides of the transformer housing 14, so that the transformer housing 14 is laterally centered on the slide 5. Then, one side slider 8 is slid so that the latch 10 on the slider 8 is aligned with one side mounting hole on the transformer housing 14. At this time, the latch on the other side slider 8 is automatically aligned with the mounting hole on the other side under the transmission action of the rack 12 and the gear 13. Then, the screws 11 on the two side sliders 8 are rotated to drive the two side pressure plates 9 downward. After the latch is inserted into the mounting hole, the pressure plates 9 press against the upper surface of the transformer housing 14 mounting seat. Because the latch on both sides is locked by the gear 13 and the rack 12, the transformer cannot slide sideways. When the transformer is operating and generating vibrations, the spring rod 4 activates the shock-absorbing and buffering effect on the slide 5.

[0029] Example 2

[0030] like Figure 1 and Figure 2 As shown, the utility model proposes a mounting bracket. Compared with the first embodiment, an exhaust pipe 2 and an air intake pipe 3 connected to the interior of the base 1 are provided, wherein a one-way valve 201 is provided on the exhaust pipe 2 to limit the direction of the internal air flow, and the one-way valve 201 is only turned on when the inner cavity 101 is exhausted, and at the same time, the inner diameter of the exhaust pipe 2 is larger than the inner diameter of the air intake pipe 3.

[0031] In this embodiment, when the transformer is working and generating vibrations, the slide 5 presses down and forces the air in the inner cavity 101 to be quickly discharged along the exhaust pipe 2 and the intake pipe 3. Then, the slide 5 slides up and resets under the tension of the spring rod 4. At this time, the outside air can only enter the inner cavity 101 along the intake pipe 2, thereby slowing down the intake speed and slowing down the extension and reset of the spring rod 4. This structure plays a role in absorbing vibrations.

[0032] Example 3

[0033] like Figure 1-Figure 3 As shown, the present invention proposes a mounting bracket. Compared with the first and second embodiments, the present embodiment further specifically discloses the structure of a drive assembly 7, which includes a bidirectional screw 71 and a crank 73. The bidirectional screw 71 is rotatably connected to the slide 5. The two ends of the bidirectional screw 71 respectively penetrate the slide 6 on the corresponding side and are spirally connected thereto. A worm gear 72 is provided at the end of the bidirectional screw 71. The crank 73 is rotatably connected to the slide 5. The crank 73 is connected to the worm 74, and the worm 74 is engaged with the worm gear 72. A guide rod 75 parallel to the bidirectional screw 71 is provided in the slide 5. The guide rod 75 penetrates the slide 6 and is slidably connected thereto.

[0034] In this embodiment, by rotating the crank 73, the crank 73 drives the worm 74 to rotate, and then drives the bidirectional screw 71 to rotate through the worm gear 72, thereby driving the slides 6 on both sides to move closer to or away from each other. On the basis of this structure, since the worm gear has the function of one-way transmission and reverse self-locking, during the vibration of the transformer, the shaking of the slide 6 will not cause the bidirectional screw 71 to rotate, thereby ensuring the installation stability of the transformer.

[0035] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
