[0041] As used in this application and the claims, unless the context clearly indicates an exception, the terms "a," "an," "an," and / or "the" are not intended to refer to the singular and may include the plural, unless the context clearly indicates otherwise. Generally speaking, the terms "comprises" and "include" only indicate the inclusion of the steps and elements specifically identified, and these steps and elements do not constitute an exclusive list. A method or apparatus may also include other steps or elements. The phrase "comprises a..." does not preclude the presence of additional identical elements in the process, method, product, or apparatus that includes the elements.

[0042] In the description of the embodiments of this application, unless otherwise specified, " / " represents or. For example, A / B can represent A or B. "And / or" in this article is simply a description of the association relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of this application, "plurality" means two or more than two.

[0043] There are three square steels on the edge of the transformer box, namely the outer square steel, the first cold-drawn square steel and the second cold-drawn square steel. The three square steels are parallel to each other. The first cold-drawn square steel is located between the outer square steel and the second cold-drawn square steel. A sealing strip is set between the first cold-drawn square steel and the second cold-drawn square steel.

[0044] See also Figures 1-6 .

[0045] Some embodiments of the present application disclose a square steel positioning device for a transformer box, comprising a counterweight box 1, a driving wheel 2, a guide assembly 3 and a positioning assembly 4. The driving wheel 2, the guide assembly 3 and the positioning assembly 4 are arranged on the side of the counterweight box 1 close to the transformer box edge.

[0046] The driving wheel 2 provides driving force to enable the counterweight box 1 to move along the transformer box;

[0047] The guide assembly 3 cooperates with the outer square steel and the first cold-drawn square steel to guide the movement of the box body 43 of the counterweight box 1, ensuring that the counterweight box 1 always moves in the guide channel formed by the outer square steel and the first cold-drawn square steel;

[0048] Positioning assembly 4 is used to position the second cold-drawn square steel. Because counterweight box 1 moves within the guide channel formed by the outer square steel and the first cold-drawn square steel, the motion trajectory of positioning assembly 4 is also parallel to the direction of the guide channel. The second cold-drawn square steel positioned by positioning assembly 4 is parallel to the guide channel. Because the guide channel is composed of the parallel outer square steel and the first cold-drawn square steel, the second cold-drawn square steel parallel to the guide channel is also parallel to the first cold-drawn square steel, ensuring parallelism between the second cold-drawn square steel and the first cold-drawn square steel.

[0049] The transformer box square steel positioning device disclosed in this scheme cooperates with the counterweight box 1, the driving wheel 2, the guide component 3 and the positioning component 4, and uses the guide component 3 to guide the movement trajectory of the counterweight box 1, so that the movement trajectory of the positioning component 4 arranged on the counterweight box 1 is parallel to the first cold-drawn square steel, and then the second cold-drawn square steel positioned by the positioning component 4 is parallel to the first cold-drawn square steel, thereby ensuring the parallelism between the first cold-drawn square steel and the second cold-drawn square steel, and then ensuring the positioning effect of the first cold-drawn square steel and the second cold-drawn square steel on the sealing strip, ensuring the reliability of the seal, and preventing oil leakage.

[0050] The driving wheel 2 provides driving force to the counterweight box 1, so that the counterweight box 1 moves in the guide channel formed by the outer square steel and the first cold-drawn square steel under the action of the guide component 3. At the same time, the positioning component 4 set on the counterweight box 1 positions the second cold-drawn square steel and determines the position of the second cold-drawn square steel. The staff preliminarily fixes the second cold-drawn square steel by electric welding along the rear of the square steel positioning device on the transformer box;

[0051] After the transformer box moves to the designated position along the square steel positioning device, the staff will fully weld the second cold-drawn square steel to complete the fixation of the transformer box along the square steel.

[0052] In this solution, the position of the second cold-drawn square steel is fully automatically positioned by the square steel positioning device along the transformer box. The positioning is based on the first cold-drawn square steel. After the position of the first cold-drawn square steel is determined, the second cold-drawn square steel is positioned. This not only ensures the parallelism of the first cold-drawn square steel and the second cold-drawn square steel, but also reduces the difficulty of positioning the second cold-drawn square steel and improves the positioning efficiency of the second cold-drawn square steel.

[0053] In some embodiments, the positioning assembly 4 includes a first positioning wheel 41 and a second positioning wheel 42 arranged in a V-shaped structure, and a second cold-drawn square steel is set at the open end of the V-shaped structure. At this time, the first positioning wheel 41 and the second positioning wheel 42 can not only guide the second cold-drawn square steel, but also press the second cold-drawn square steel to improve the positioning effect of the second cold-drawn square steel. During the welding process, only a very small force needs to be provided to make the second cold-drawn square steel fit against the edge of the transformer box.

[0054] During the process of positioning the second cold-drawn square steel, the first positioning wheel 41 and the second positioning wheel 42 rotate along the surface of the second cold-drawn square steel, reducing the friction between the positioning assembly 4 and the second cold-drawn square steel, and improving the flexibility of the transformer box moving along the square steel positioning device.

[0055] Optionally, the positioning assembly 4 is connected to the box body 43 by an adjusting bolt. The adjusting bolt can not only realize the fixed connection between the positioning assembly 4 and the counterweight box 1, but also can adjust the position of the positioning assembly 4 according to the position requirements of the second cold-drawn square steel, so that the transformer box along the square steel positioning device is suitable for different types of transformers or reactors, etc.

[0056] In some embodiments, the positioning component 4 can also be a positioning block, on which a positioning groove is provided, and the positioning groove cooperates with the second cold-drawn square steel to achieve positioning of the second cold-drawn square steel; optionally, a roller is provided on the groove wall of the positioning groove to abut against the second cold-drawn square steel to reduce the friction between the positioning block and the second cold-drawn square steel.

[0057] In order to further optimize the positioning effect of the second cold-drawn square steel, the middle of the outer periphery of the first positioning wheel 41 and the second positioning wheel 42 has a positioning groove that matches the edge of the second cold-drawn square steel. Figure 6 As shown, the shape of the groove wall of the positioning groove is consistent with the shape of the edge of the second cold-drawn square steel, and the groove wall of the positioning groove is in contact with the top wall and side walls on both sides of the edge of the second cold-drawn square steel.

[0058] In some embodiments, the positioning assembly 4 is slidingly connected to the counterweight box 1. Specifically, the positioning assembly 4 also includes a box body 43, and a slide is provided on one of the box body 43 and the counterweight box 1, and a slide groove is provided on the other of the box body 43 and the counterweight box 1. The box body 43 and the counterweight box 1 are slidingly connected through the cooperation of the slide and the slide groove.

[0059] This solution also provides a limiter 11 on the counterweight box 1 to limit the highest position of the box body 43 on the counterweight box 1. When the box body 43 moves to the position of the limiter 11 of the counterweight box 1, the limiter 11 abuts against the upper end of the box body 43. When the counterweight box 1 is located above the edge of the transformer box, the positioning assembly 4 abuts against the second cold-drawn square steel. Under the action of the gravity of the counterweight box 1, the positioning assembly 4 presses the second cold-drawn square steel against the edge of the transformer box. At the same time, the second cold-drawn square steel applies a thrust to the positioning assembly 4, causing the positioning assembly 4 to push the box body 43 upward until it abuts against the limiter 11. At this time, the positioning assembly 4 can stably position the second cold-drawn square steel.

[0060] In some embodiments, a baffle 44 is provided on the box body 43, and a compression spring 5 is provided between the baffle 44 and the limit member 11. One end of the compression spring 5 is connected to the limit member 11, and the other end of the compression spring 5 is connected to the baffle 44. The compression spring 5 is used to apply downward pressure to the baffle 44.

[0061] When the counterweight box 1 is located above the edge of the transformer box, the positioning assembly 4 presses the second cold-drawn square steel on the edge of the transformer box under the action of the gravity of the counterweight box 1. The second cold-drawn square steel simultaneously applies a thrust to the positioning assembly 4, causing the positioning assembly 4 to push the box body 43 upward to squeeze the compression spring 5. At the same time, the compression spring 5 applies a downward pressure to the baffle 44 of the box body 43, further pressing the positioning assembly 4 on the edge of the second cold-drawn square steel.

[0062] The guide assembly 3 includes a first guide wheel assembly and a second guide wheel assembly, wherein the first guide wheel assembly includes a first inner guide wheel 31 and a first outer guide wheel 32 , and the second guide wheel assembly includes a second inner guide wheel 33 and a second outer guide wheel 34 .

[0063] like Figure 4-Figure 6 As shown, the first inner guide wheel 31 and the first outer guide wheel 32 are respectively located on both sides of the length direction of the first cold-drawn square steel. The first inner guide wheel 31 is located on the side of the first cold-drawn square steel close to the outer square steel, and the first outer guide wheel 32 is located on the side of the first cold-drawn square steel away from the outer square steel. The first cold-drawn square steel is sandwiched between the first inner guide wheel 31 and the first outer guide wheel 32.

[0064] The second inner guide wheel 33 and the second outer guide wheel 34 are respectively located on both sides of the length direction of the outer square steel. The second inner guide wheel 33 is located on the side of the outer square steel close to the first cold-drawn square steel, and the second outer guide wheel 34 is located on the side of the outer square steel away from the first cold-drawn square steel. The outer square steel is sandwiched between the second inner guide wheel 33 and the second outer guide wheel 34.

[0065] The guide assembly 3 disclosed in this solution cooperates with the first cold-drawn square steel and the outer square steel to guide and improve the stability of the counterweight box 1 moving on the edge of the transformer box.

[0066] The square steel positioning device for the transformer box edge disclosed in this solution cooperates with the square steel on the transformer box edge through the guide assembly 3, and does not require a separate guide structure, thereby simplifying the structure of the square steel positioning device for the transformer box edge.

[0067] The guide assembly 3 is not limited to the above structure, and can also be a guide groove provided below the counterweight box 1 to cooperate with the first cold-drawn square steel and the outer square steel, and cooperate with the first cold-drawn square steel and the outer square steel through the guide groove.

[0068] The first inner guide wheel 31 and the second inner guide wheel 33 are fixedly connected to the counterweight box 1. The transformer box is positioned between the first cold-drawn square steel and the outer square steel through the first inner guide wheel 31 and the second inner guide wheel 33 along the square steel positioning device to prevent the counterweight box 1 from shaking along the length direction perpendicular to the first cold-drawn square steel, thereby improving the positioning stability.

[0069] Optionally, the first inner guide wheel 31 and the second inner guide wheel 33 are connected to the counterweight box 1 by adjusting bolts. Those skilled in the art can fine-tune the positions of the first inner guide wheel 31 and the second inner guide wheel 33 according to the distance between the first cold-drawn square steel and the outer square steel, so that the first inner guide wheel 31 and the second inner guide wheel 33 can respectively abut against the first cold-drawn square steel and the outer square steel.

[0070] The first outer guide wheel 32 and the second outer guide wheel 34 can be fixedly connected to the counterweight box 1 or movably connected.

[0071] In an embodiment in which the first outer guide wheel 32 and the second outer guide wheel 34 are movably connected to the counterweight box 1, the first outer guide wheel 32 can adapt to the surface convexity and concaveity changes of the first cold-drawn square steel on the side away from the outer square steel, and the second outer guide wheel 34 can adapt to the surface convexity and concaveity changes of the outer square steel on the side away from the first cold-drawn square steel, thereby avoiding burrs or unevenness on the outside of the first cold-drawn square steel and the outer square steel that affect the movement of the counterweight box 1.

[0072] The first outer guide wheel 32 and the second outer guide wheel 34 are movably connected to the counterweight box 1 through a movable connection component 6 . The movable connection component 6 includes a guide rail 61 , a first slider 62 , a second slider 63 and an elastic member 64 .

[0073] The guide rail 61 is installed on the counterweight box 1, and the length direction of the guide rail 61 is perpendicular to the length direction of the first cold-drawn square steel;

[0074] The first slider 62 and the second slider 63 are installed at both ends of the guide rail 61 in the longitudinal direction. The first slider 62 and the second slider 63 are slidably connected to the guide rail 61. The first slider 62 is connected to the first outer guide wheel 32, and the second slider 63 is connected to the second outer guide wheel 34.

[0075] The middle part of the elastic member 64 is connected to the guide rail 61 or the counterweight box 1, one end of the elastic member 64 is connected to the first slider 62, and the other end of the elastic member 64 is connected to the second slider 63. The elastic member 64 is used to apply tension to the first slider 62 and the second slider 63 so that the first outer guide wheel 32 and the second outer guide wheel 34 are respectively fitted with the first cold-drawn square steel and the outer square steel.

[0076] When the counterweight box 1 moves along the transformer box, if there are burrs or other protrusions on the outside of the first cold-drawn square steel and / or the outer square steel, the first slider 62 and / or the second slider 63 moves along the guide rail 61 toward the end of the guide rail 61 in the longitudinal direction. At this time, the first outer guide wheel 32 moves with the first slider 62 and / or the second outer guide wheel 34 moves with the second slider 63, so that the first outer guide wheel 32 and / or the second outer guide wheel 34 move outward within a certain range of lateral movement, and after passing the burrs and other protrusions, the first slider 62 and / or the second slider 63 can move toward the middle of the guide rail 61 in the longitudinal direction under the action of the elastic member 64, and the first outer guide wheel 32 moves with the first slider 62 and / or the second outer guide wheel 34 moves with the second slider 63, so as to realize the resetting of the first outer guide wheel 32 and / or the second outer guide wheel 34.

[0077] In this embodiment, the first outer guide wheel 32 and the second outer guide wheel 34 share a movable connection assembly 6 to be connected to the counterweight box 1 .

[0078] In other embodiments, the first outer guide wheel 32 and the second outer guide wheel 34 can be respectively connected to the counterweight box 1 through their own movable connection components 6. Specifically, the movable connection component 6 includes a slider, a guide rail 61 and an elastic member 64. The guide rail 61 is connected to the counterweight box 1, and the length direction of the guide rail 61 is perpendicular to the length direction of the first cold-drawn square steel. The slider is slidably connected to the guide rail 61. The slider is connected to the outer guide wheel (the outer guide wheel here refers to the first outer guide wheel 32 or the second outer guide wheel 34). One end of the elastic member 64 is connected to the slider, and the other end of the second elastic member 64 is connected to the guide rail 61 or the counterweight box 1.

[0079] Both of the above-mentioned methods can achieve independent adjustment of the positions of the first outer guide wheel 32 and the second outer guide wheel 34 .

[0080] A magnet or electromagnet 7 is provided on one side of the counterweight box 1 close to the edge of the transformer box.

[0081] In the embodiment in which the electromagnet 7 is provided on the counterweight box 1, when working, the electromagnet 7 is energized to adsorb the counterweight box 1 on the edge of the transformer box, ensuring that the positioning assembly 4 can always be pressed against the edge of the transformer box; after the work is completed, the electromagnet 7 is de-energized to release the adsorption force between the electromagnet and the edge of the transformer box, and the square steel positioning device along the transformer box is removed.

[0082] The counterweight box 1 may be provided with only one electromagnet 7 or may be provided with multiple electromagnets 7 according to actual needs.

[0083] The counterweight box 1 can be a solid counterweight box or a hollow counterweight box.

[0084] In an embodiment where the counterweight box 1 is hollow, the counterweight box 1 has a cavity with slots for accommodating counterweights to ensure sufficient compressive force between the positioning assembly 4 and the second cold-drawn square steel. In this embodiment, the compressive force exerted by the positioning assembly 4 on the second cold-drawn square steel can be adjusted according to the number of counterweights required.

[0085] The counterweight box 1 can also store energy supply devices such as batteries and control devices such as circuit components used for the operation of the device.

[0086] In order to facilitate the transportation of the transformer box along the square steel positioning device, this solution provides a handle on the counterweight box 1, which is convenient for single-handed holding and carrying of the transformer box along the square steel positioning device.

[0087] In some embodiments, the driving wheel 2 is located in front of the counterweight box 1 , the positioning assembly 4 is located behind the counterweight box 1 , and the guide assembly 3 is located between the driving wheel 2 and the positioning assembly 4 .

[0088] The guide assembly 3 is located between the drive wheel 2 and the positioning assembly 4, which increases the flexibility of selecting the position of the guide assembly 3. Optionally, at least two sets of guide assemblies 3 are provided on the counterweight box 1 along the length direction of the first cold-drawn square steel, with one set of guide assemblies 3 being located near the drive wheel 2 and the other set of guide assemblies 3 being located near the positioning assembly 4.

[0089] In some embodiments, the positioning assembly 4 is located in front of the counterweight box 1, the driving wheel 2 is located behind the counterweight box 1, and the guide assembly 3 is located between the driving wheel 2 and the positioning assembly 4;

[0090] In some embodiments, a driving wheel 2 is provided in front of or behind the counterweight box 1, and a positioning assembly 4 is provided in front and behind the counterweight box 1.

[0091] In some embodiments, the driving wheel 2 and the positioning assembly 4 may also be arranged in the middle position of the counterweight box 1.

[0092] During operation, the driving wheel 2 drives the transformer box to move along the square steel positioning device on the edge of the transformer box. Only one person needs to press the start button at the start time, and the transformer box along the square steel positioning device can move by itself and lay the second cold-drawn square steel by itself, reducing the difficulty of laying the second cold-drawn square steel.
