[0030] Three support columns 9 are arranged on the upper and lower parts of the left and right sides of the mounting frame 2, the support columns 9 pass through the mounting frame 2 and the left and right hanging frames 3, the outer ends of the support columns 9 are provided with threaded heads 11, the outer sides of the threaded heads 11 are provided with two embedded plates 10 and fixing nuts 12, the two embedded plates 10 are respectively located at the inner and outer ends of the left and right sides of the mounting frame 2, the three support columns 9 are triangularly distributed to form a stable support system, and the inner and outer sides are clamped through the threaded heads 11, the embedded plates 10 and the fixing nuts 12 after passing through the mounting frame 2 and the hanging frame 3; the embedded plates 10 increase the stress area to prevent the surface of the mounting frame 2 from deforming, and the pre-tightening force of the fixing nuts 12 makes the inner side of the support column 9 abut against the inner wall of the channel steel 1 to form a rigid support structure, thereby improving the overall overturning resistance.

[0031] As shown in Figure 1 and Figure 7 , the bottom of the mounting frame 2 is fixedly connected with a connecting frame 13, the upper part of the connecting frame 13 is fixedly connected with a winding device 14, the left side of the connecting frame 13 is fixedly connected with a driving motor 15, the rotating shaft of the driving motor 15 is fixedly connected with the rotating shaft of the winding device 14, the bottom end of the connecting frame 13 is provided with a circular groove 1301, the telescopic rope of the winding device 14 is located at the circular groove 1301, and the bottom end of the telescopic rope of the winding device 14 is used for hanging lamps, the driving motor 15 drives the winding device 14 to realize automatic winding and unwinding of the telescopic rope, the circular groove 1301 guides the telescopic rope to avoid deviation during winding; the lamp hanging height can be accurately adjusted through motor control, manual climbing operation is not required, the installation safety and efficiency are improved, and the lamp height dynamic adjustment is suitable for high-altitude steel frame scenes.

[0032] As shown in Figure 1 and Figure 4 , the outer side of the hanging frame 3 is fixedly connected with a rotating seat 5, the inner side of the rotating seat 5 is rotatably connected with the inner end of the threaded column 4, the rotating seat 5 provides a rotating support point for the threaded column 4, so that the threaded column 4 maintains coaxiality during adjustment, and threaded wear caused by eccentric stress is avoided; the rotating connection design of the rotating seat 5 and the threaded column 4 allows the threaded column 4 to drive the hanging frame 3 to translate during rotation, ensures the stability of the adjustment action, and reduces the difficulty of installation operation.

[0033] As shown in Figures 1-4 , the left and right sides of the mounting frame 2 are provided with first fixed sleeves 203, the outer sides of the hanging frames 3 are provided with second fixed sleeves 303, and springs 6 are arranged between the first fixed sleeves 203 and the second fixed sleeves 303, the springs 6 connect the first fixed sleeves 203 and the second fixed sleeves 303 to form an elastic buffer structure, when the steel frame is vibrated, the compression and stretching of the springs 6 can absorb vibration energy, and the rigid impact between the mounting frame 2 and the hanging frame 3 is reduced; the pre-tightening force of the springs 6 can assist in maintaining the position of the hanging frame 3, prevent the threaded column 4 from loosening due to vibration, and improve the structure's anti-seismic performance.

[0034] Please see Figure 3 As shown, the bottom front and rear sides of the mounting bracket 3 are provided with sliding protrusions 301, and the middle of each sliding protrusion 301 is rotatably connected to a roller 302. The bottom front and rear ends and left and right sides of the mounting bracket 2 are provided with sliding grooves 201. The rollers 302 are respectively rotatably connected to the inner side of the corresponding sliding grooves 201. The combination of sliding protrusions 301 and rollers 302 converts sliding friction into rolling friction, reducing the sliding resistance of the mounting bracket 3 on the mounting bracket 2 by more than 70%. The rollers 302 roll in the sliding grooves 201, allowing the mounting bracket 3 to be adjusted laterally for slight adjustments, which is convenient for aligning with the installation position of the channel steel 1, improving installation accuracy and convenience.

[0035] Please see Figures 2-6 As shown, a first adsorption magnet 204 is fixedly connected to the bottom of the mounting bracket 2. The first adsorption magnet 204 is adsorbed to the bottom of the I-shaped channel steel 1. The bottom of the snap-fit ​​bracket 8 is at the same level as the upper part of the I-shaped channel steel 1. A second adsorption magnet 16 is fixedly connected to the bottom of each snap-fit ​​bracket 8. The second adsorption magnet 16 is adsorbed to the front and rear sides of the upper part of the I-shaped channel steel 1 respectively. The first adsorption magnet 204 and the second adsorption magnet 16 use magnetic force to adsorb the channel steel 1, forming an auxiliary fixing structure. Magnetic adsorption can achieve pre-positioning before mechanical fixing, preventing the mounting bracket 2 from falling off, and at the same time enhancing the pull-out resistance of the overall connection. The upper and lower magnets cooperate with mechanical snap-fit ​​to form a double insurance mechanism of "magnetic pre-fixing + mechanical strong locking".

[0036] Please see Figures 1-7 As shown, the mounting bracket 2 has an inverted U-shaped structure, and the hanging brackets 3 both have a 7-shaped structure. Both the mounting bracket 2 and the hanging brackets 3 are made of stainless steel and have an anti-rust coating on the surface. The structural design of the inverted U-shaped mounting bracket 2 and the 7-shaped hanging bracket 3 conforms to the mechanical bending moment distribution, which can effectively disperse the stress generated by the load of the lamp. The 304 stainless steel material combined with the anti-rust coating enables the structure to maintain corrosion resistance in harsh environments such as humidity and dust. Salt spray test shows that the anti-rust life can reach more than 5 years, reducing maintenance costs.

[0037] The inner side of the mounting bracket 3 is fitted with the outer edge of the I-shaped channel steel 1, and the inner end of the support column 9 abuts against the inner side of the I-shaped channel steel 1. Rubber pads are provided on both the left and right ends of the inner side of the I-shaped channel steel 1, and the rubber pads pass through the support column 9. The fitting design between the inner side of the mounting bracket 3 and the edge of the channel steel 1 ensures a fit of more than 95% during installation, reducing installation gaps. The support column 9 abuts against the inner side of the channel steel 1, and with the buffering effect of the rubber pads, it not only enhances friction to prevent slippage, but also avoids damage to the surface of the channel steel caused by rigid contact. The rubber pads also serve as insulation to prevent static electricity generated by metal friction.

[0038] Please see Figures 1-7As shown, the inner side end surface of the support column 9 is provided with anti-skid lines, which abut against the inner walls of the through holes of the mounting frame 2 and the hanging frame 3, so as to enhance the friction between the support column 9 and the mounting frame 2 and the hanging frame 3;

[0039] Please refer to Figures 1-7 As shown, the outer side end surface of the threaded column 4 is provided with a rotating handle and a hexagonal driving groove, which is suitable for a wrench or screwdriver tool, so as to facilitate the rotation adjustment of the threaded column 4. The anti-skid lines are designed in a zigzag shape, and the surface roughness Ra=6.3μm, so that the friction coefficient between the support column 9 and the inner wall of the through hole is increased to 0.8, effectively preventing the axial movement of the support column 9 in vibration. The line structure simultaneously increases the contact area, so that the torsional stiffness of the support column 9 is increased by 30%, ensuring the connection stability in long-term use.

[0040] The implementation principle of the embodiment of the present application is as follows: first, the upper part of the hanging frame 3 in the 7-shaped structure is hung on the left and right side edges of the I-shaped channel steel 1, and the inner side thereof is matched with the outer side edge of the I-shaped channel steel 1 to achieve preliminary positioning. The sliding block 301 at the bottom of the hanging frame 3 drives the roller 302 to be embedded in the sliding groove 201 of the mounting frame 2, so that the hanging frame 3 can slide left and right along the mounting frame to facilitate alignment, and then the rotating handle on the outer side of the threaded column 4 is rotated or rotated by a tool through the hexagonal driving groove. The threaded column 4 is pushed inward through the threaded sleeve 203, and the inner end thereof abuts against the rotating seat 5 to push the hanging frame 3 to move towards the I-shaped channel steel 1 until the upper part of the hanging frame 3 tightly abuts against the I-shaped channel steel 1. The rotating clamping frame 8 is rotated to make the clamping protrusion 801 clamped into the clamping groove 304 to form mechanical clamping to prevent the hanging frame from shaking up and down. Secondly, the support column 9 passes through the through holes of the mounting frame 2 and the hanging frame 3, and the anti-skid lines on the inner side end surface thereof abut against the hole wall to increase the friction. The threaded head 11 at the outer end of the support column passes through the inner side embedded plate 10 and the mounting frame 2 in sequence, and is tightened by the fixing nut 12 to fix the mounting frame 2 and the hanging frame 3. The rubber pad at the inner side of the I-shaped channel steel 1 passes through the support column to play a buffering and anti-skid role. Further, the spring 6 between the first fixing sleeve 203 and the second fixing sleeve 303 is in a compressed state to provide elastic support for the hanging frame 3 to relieve the vibration after installation. The first adsorbing magnet 204 at the bottom of the mounting frame 2 is adsorbed on the bottom of the channel steel, and the second adsorbing magnet 16 at the bottom of the clamping frame 8 is adsorbed on the front and rear sides of the upper part of the channel steel to further enhance the structural stability by magnetic force. Finally, the connecting frame 13 is fixed at the bottom of the mounting frame, the winding device 14 is located at the upper part of the connecting frame 13, the driving motor 15 drives the rotating shaft of the winding device to rotate, the lamp is hung at the bottom end of the telescopic rope of the winding device 14, the winding device is controlled to wind and unwind the rope by the driving motor 15, the telescopic rope passes through the circular groove 1301 at the bottom end of the connecting frame to realize precise adjustment of the height of the lamp.
