Description

Technical Field

[0001] This invention relates to the field of transformer mounting support components, specifically a suspended transformer mounting support frame. Background Technology

[0002] In scenarios such as power transmission and distribution network construction, urban power grid transformation, and industrial plant power distribution system construction, suspended transformers are widely used in various high and low voltage power distribution systems due to their advantages such as small footprint, flexible installation, and convenient maintenance. The stable operation of suspended transformers highly depends on the reliability of the mounting support structure; therefore, the suspended transformer mounting support frame has become an indispensable core component in the power distribution system.

[0003] A search revealed that CN110783063B discloses a transformer mounting structure and a pole-mounted transformer mounting bracket. The pole-mounted transformer mounting bracket includes spaced crossarms; it also includes a pressing beam for pressing against the bottom support beam of the transformer; each crossarm has a transition support, and one of the transition support and crossarms has a positioning bolt, the axis of which extends along the crossarm spacing direction; the other of the transition support and crossarms has a horizontal limiting surface for engaging with the tail end of the positioning bolt along the crossarm spacing direction; each crossarm has its own corresponding positioning bolt; the transition support also has a positioning structure for horizontally positioning and engaging with the bottom support beam of the transformer, thus achieving both transformer positioning in different crossarm spacing directions and allowing for convenient transformer installation by first installing the transition support and then the transformer.

[0004] Existing suspended transformer mounting supports have the following drawbacks: poor adaptability. Traditional support frames have fixed installation spacing, which cannot flexibly adapt to the differences in column spacing in different scenarios. When dealing with columns with non-standard spacing, additional customization or adapters are required, which not only increases construction costs but also extends the installation period. Insufficient stability. The fastening structure of conventional support frames is mostly a single clamp or bolt fixation. Under the influence of vibration generated by the long-term operation of the transformer, problems such as clamp loosening and support slippage and tilting are prone to occur, which may threaten the safe operation of the power distribution system in severe cases.

By setting a telescopic extension plate and fixing it with a first clamp, and by setting the fastening mechanism as two separate structures, an upper fastening plate and a lower fastening plate, the fastening mechanism can extend to adapt to columns with different spans, achieving the effect of adapting to various spacing mounting support frames, and solving the problem of inconsistent installation due to different column spacings.

[0020] 2. The suspended transformer mounting support frame is configured with two sets of upper and lower fastening plates, which allow the inclined fastening bracket to distribute the force to the columns on both sides when under pressure. This ensures that the fastening bracket can fit tightly with the columns after being stressed. By setting anti-slip sleeves, the first and second clamps are prevented from sliding on the column surface, thus solving the problem of the mounting frame sliding on the column surface and causing tilting due to transformer vibration.

[0021] 3. The suspended transformer mounting support frame, by setting up the suspension frame, enables the transformer and supporting equipment to be quickly and conveniently assembled on the top placement frame and the bottom suspension plate. By setting up the suspension plate, the connecting wires on the surface of the transformer can be separated from the equipment above, preventing electric arc from connecting with the equipment above. The multi-hole setting of the suspension plate can enhance the sound insulation effect, thus achieving the effect of ensuring the safety of surrounding equipment and personnel.

A sealing head is provided at one end of the extension plate 112 located inside the extension shell 111, and a first clamp 1121 is fixedly provided at the end of the extension plate 112 away from the sealing head.

[0042] In this embodiment, the sealing head can prevent the extension plate 112 from completely sliding out of the extension shell 111, and the reinforcing rib can improve the structural strength of the extension plate 112 and avoid deformation under stress.

[0043] In an optional embodiment, the erection plate 12 has two sets respectively arranged on both sides of the extension mechanism 11, and the upper surface of the erection plate 12 is provided with a second positioning bolt 121, and the two ends of the erection plate 12 are erected above the sides of the first clamp 1121.

[0044] In this embodiment, the erection plate 12 can enhance the overall stability of the positioning base plate 1, and together with the first positioning bolt 1111, it can achieve precise positioning and fixation of the connecting seat 21.

[0045] In an optional embodiment, the lower surface of the connector 21 is provided with a groove, which wraps around the outside of the first positioning bolt 1111 and the second positioning bolt 121. The side of the connector 21 is provided with a screw, which passes through the connector 21 and is threadedly connected to the first positioning bolt 1111 and the second positioning bolt 121.

[0046] In this embodiment, the connecting seat 21 is connected to the first positioning bolt 1111 and the second positioning bolt 121 by screws, so that the positioning base plate 1 and the connecting seat 21 form a whole.

[0047] In an optional embodiment, the lifting assembly 22 includes a lifting telescopic rod 221 and a dustproof telescopic sleeve 222. The lifting telescopic rod 221 is fixedly mounted on the upper end of the connecting seat 21, and the free end of the lifting telescopic rod 221 is fixedly connected to the arch corner block 31. The dustproof telescopic sleeve 222 wraps around the outside of the lifting telescopic rod 221.

[0048] In this embodiment, the dustproof telescopic sleeve 222 can effectively block dust and rainwater from entering the interior of the lifting telescopic rod 221, prevent component corrosion, and extend the service life of the lifting assembly 22.

[0049] In an optional embodiment, the fastening bracket 32 ​​includes an upper fastening plate 321, a lower fastening plate 322, and a limiting shell 323; the upper end of the upper fastening plate 321 is hinged to the arched corner block 31, and the lower surface of the upper fastening plate 321 is provided with ratchet teeth; the upper surface of the lower fastening plate 322 is provided with ratchet teeth, and the lower end of the lower fastening plate 322 is hinged to a second clamp 3221, the inner side of the second clamp 3221 is provided with an anti-slip sleeve 3222, and the anti-slip sleeve 3222...

[0050] In this embodiment, the ratchet engagement structure enables flexible adjustment of the length of the fastening bracket 32, and has a self-locking function after engagement, improving the stability of the support structure; the anti-slip sleeve 3222 can increase the friction between the second clamp 3221 and the column, preventing the bracket from sliding down, and at the same time avoiding direct contact between the clamp and the column surface, which would cause wear. After the arch corner block 31 is subjected to force, the fastening bracket 32 ​​is tilted, which will tilt the force to the column, so that the greater the force on the fastening bracket 32, the tighter the fit between it and the column.

[0051] In an optional embodiment, the suspension bracket 4 includes a top-level placement bracket 41, a suspension frame 42, and a bottom-level suspension plate 43.

Wrap the anti-slip sleeve 3222 around the outside of the columns, and use the first clamp 1121 to fix the height of the extension mechanism 11. After the extension mechanism 11 is installed, place the erection plate 12 above the first clamp 1121 on both sides, install the connecting seat 21 above the extension mechanism 11, and use screws to fix the connecting seat 21 to the first positioning bolt 1111 and the connecting seat 21 to the second positioning bolt 121.
