[0002] The structural beams are part of the electrical equipment; they are steel structures with anti-corrosion treatment.

[0003] During the expansion of substations, the different installation environments of new and old equipment often result in the inability to precisely align the structural beams that need to be connected, or they may be misaligned. This necessitates the use of custom-made structural beams with specific angles for connection. Due to the different misalignment angles, structural beams of various sizes and angles need to be prepared, as traditional structural beams cannot be adjusted according to installation requirements. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable frame beam for substation expansion. Through a separate design of the first and second frame beam bodies, when adjustment is needed, the adjustment component can be driven manually to extend the adjustment screw outwards, allowing the first and second frame beam bodies to rotate and adjust using the first mounting bolt. Adjusting the included angle between the first and second frame beam bodies allows for adjustment of the deflection direction and angle as needed, achieving a docking connection between the two sets of frame beams, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable frame beam for substation expansion, comprising a first frame beam body and a second frame beam body, the first frame beam body and the second frame beam body being rotatably connected to opposite sides, an adjusting box being movably connected inside the first frame beam body via a mounting seat, the inner cavity of the adjusting box being provided with two sets of adjusting screws, the inner cavity of the adjusting box being provided with an adjusting component for synchronously extending and retracting the two sets of adjusting screws, and the adjusting box also being provided with a manual driving component for driving the adjusting component, a connecting rod being movably connected to the second frame beam body via a mounting seat, the connecting rod being movably connected to the opposite end of the adjusting screws.

Detailed Implementation

[0020] 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.

[0021] This utility model provides, for example Figures 1-4 The adjustable frame beam shown is based on the expansion of a substation and includes a first frame beam body 1 and a second frame beam body 2. The first frame beam body 1 and the second frame beam body 2 are rotatably connected to each other on opposite sides. An adjustment box 3 is movably connected inside the first frame beam body 1 through a mounting seat. The inner cavity of the adjustment box 3 is provided with two sets of adjustment screws 4. The inner cavity of the adjustment box 3 is provided with an adjustment component 5 for synchronously extending and retracting the two sets of adjustment screws 4. The adjustment box 3 is also provided with a manual drive component 6 for driving the adjustment component 5. A connecting rod 7 is movably connected to the second frame beam body 2 through a mounting seat. The connecting rod 7 is movably connected to the opposite end of the adjustment screws 4.

[0022] After the adjusting screw 4 is connected to the connecting rod 7, the first frame beam body 1 and the second frame beam body 2 can rotate around the first mounting bolt 8. Then, the manual drive component 6 is used to drive the adjusting component 5, causing the adjusting screw 4 to move telescopically. This, in conjunction with the connecting rod 7, changes the included angle between the first frame beam body 1 and the second frame beam body 2, thereby adjusting the position of the first frame beam body 1 and the second frame beam body 2, facilitating the docking of the two sets of misaligned frame beams.

[0023] like Figure 2As shown: The adjusting assembly 5 includes two sets of threaded cylinders 51 that rotate within the inner cavity of the adjusting box 3 via bearings. The end of the adjusting screw 4 away from the connecting rod 7 is threaded through the inner cavity of the threaded cylinder 51. A rotating shaft 52 is movably mounted in the inner cavity of the adjusting box 3 via a mounting base. Drive helical gears 53 are fixed at both ends of the rotating shaft 52. A driven helical gear 54 that meshes with the drive helical gear 53 is fixed on the outer side of the threaded cylinder 51. The rotating shaft 52 drives the drive helical gears 53 at both ends to rotate. Subsequently, the drive helical gears 53 rotate synchronously with the driven helical gear 54, thereby causing the two sets of adjusting screws 4 to move synchronously.

[0024] like Figure 2 As shown: The manual drive assembly 6 includes a worm gear 61 that rotates within the cavity of the adjustment box 3 via a bearing. One end of the worm gear 61 extends to the outside of the adjustment box 3 and is fixed with a handle 62. A worm wheel 63 that meshes with the worm gear 61 is fixed at the center of the rotating shaft 52. The worm gear 61 is driven to rotate by the handle 62, which in turn drives the rotating shaft 52 in conjunction with the worm wheel 63. At the same time, the worm wheel 63 and the worm gear 61 have a self-locking structure to prevent the angle from deflecting again after adjustment.

[0025] like Figure 3 As shown: A first mounting hole is provided on the opposite side of the first frame beam body 1 and the second frame beam body 2, and a first mounting bolt 8 is inserted into the first mounting hole. One end of the first mounting bolt 8 is threadedly connected to a first mounting nut 9. Through the cooperation of the first mounting bolt 8 and the first mounting nut 9, the first frame beam body 1 and the second frame beam body 2 can be easily rotated and adjusted about the first mounting bolt 8 as the axis.

[0026] like Figure 3 As shown: The first frame beam body 1 and the second frame beam body 2 are both fixed with mounting flanges 10 on the opposite side of each other. The mounting flanges 10 are locked and fixed by the second mounting bolts 11 and the second mounting nuts 12. The mounting flanges 10 can be connected by the second mounting bolts 11 and the second mounting nuts 12 to achieve a stable connection between the first frame beam and the second frame beam.

[0027] like Figure 3-4 As shown: A second mounting hole is provided at one end of the adjusting screw 4 and the connecting rod 7 facing each other. A third mounting bolt 13 is movably installed in the inner cavity of the second mounting hole. Both ends of the third mounting bolt 13 pass through to the outside of the connecting rod 7 and are threadedly connected to a third mounting nut 14. The cooperation of the third mounting bolt 13 and the third mounting nut 14 facilitates the connection of the adjusting screw 4 and the connecting rod 7, and at the same time, it can realize the movable folding of the adjusting screw 4 and the connecting rod 7 to meet the multi-angle adjustment needs of the first frame beam body 1 and the second frame beam body 2.

[0028] like Figure 1As shown: The first frame beam body 1 and the second frame beam body 2 are both welded together from four sets of beams and columns and multiple sets of support rods. By limiting the structure of the first frame beam body 1 and the second frame beam body 2, the stability of the structure is improved, while multi-angle adjustment of the device can be realized at the same time.

[0029] In practical use, the first frame beam body 1 and the second frame beam body 2 are brought close together. The first mounting bolt 8 is used to movably connect the opposing sides of the first frame beam body 1 and the second frame beam body 2. Simultaneously, the third mounting bolt 13 and the third mounting nut 14 enable the movable connection between the adjusting screw 4 and the connecting rod 7. Then, the other opposing sides of the first frame beam body 1 and the second frame beam body 2 are connected to the mounting flange 10 using the second mounting bolt 11 and the second mounting nut 12, achieving a stable connection between the first frame beam body 1 and the second frame beam body 2. When it is necessary to adjust the first frame beam body 1 and the second frame beam body 2... When adjusting the main body 2 of the second frame beam, remove the second mounting bolt 11 and the second mounting nut 12, then rotate the handle 62 to drive the worm gear 61. The worm gear 61 then drives the rotating shaft 52 through the worm wheel 63, causing the driving helical gears 53 at both ends of the rotating shaft 52 to rotate synchronously. In addition, the driven helical gear 54 on the outside of the threaded cylinder 51 makes the two sets of threaded cylinders 51 rotate synchronously, causing the adjusting screw 4 to extend outward and the main body 2 of the second frame beam to deflect. Multiple sets of the main body 1 of the first frame beam and the main body 2 of the second frame beam can be set on the frame beam to realize the docking of spatial coordinates.

[0030] 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 these 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.
