Description

[0002] Currently, lighting fixtures in steel structures are commonly installed using welding, bolting, or chain suspension. While welding offers stability, it suffers from long construction times and difficult maintenance. Bolting requires pre-drilling, which impacts the strength of the steel beams. Chain suspension is cumbersome to adjust the height and suffers from poor stability. With the increasing popularity of modular construction and prefabricated construction, an installation solution that balances efficiency and reliability is needed. In recent years, newer mounting structures such as magnetic attachment and snap-on clamps have emerged, but they often suffer from insufficient load-bearing capacity and poor seismic performance.

[0016] The following is combined with Figure 1 -Attached Figure 7 , further details of this application are given.

[0017] Example: See also Figure 1-Figure 7 As shown, the present invention provides a technical solution: a quick installation structure for lamps on a top steel frame, comprising an I-shaped channel steel 1 and a mounting frame 2, wherein the left and right sides of the mounting frame 2 are slidably connected to a hanging frame 3, and the upper portion of the hanging frame 3 is respectively hung on the left and right sides of the I-shaped channel steel 1, and the middle portions of the left and right sides of the mounting frame 2 are provided with a threaded sleeve 202, and the inner sides of the threaded sleeve 202 are threadedly connected to a threaded column 4, and the upper portions of the left and right hanging frames 3 are provided with a fixing seat 7 and a clamping groove 304, and the inner sides of the fixing seat 7 are rotatably connected to a clamping frame 8, The outer ends of the clamping frame 8 are all provided with clamping protrusions 801, and the clamping protrusions 801 are all clamped and connected with the corresponding clamping grooves 304. The hanging frame 3 is quickly positioned with the I-shaped channel steel 1 through the upper hanging structure, and the sliding connection design allows horizontal adjustment; the threaded transmission of the threaded column 4 and the threaded sleeve 202 can accurately control the clamping force of the hanging frame 3. The clamping frame 8 is rotated to make the clamping protrusions 801 fit into the clamping grooves 304, forming a mechanical locking structure to prevent the hanging frame 3 from moving up and down, thereby realizing a three-step quick installation of hanging, adjustment, and clamping; Three support columns 9 are provided on the upper left and right sides and the front and rear sides of the lower part of the mounting frame 2, which pass through the mounting frame 2 and the left and right hanging frames 3 respectively. The outer ends of the support columns 9 are provided with threaded heads 11, and two mosaic plates 10 and fixing nuts 12 are provided on the outer sides of the threaded heads 11. The two mosaic 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 distributed in a triangular shape to form a stable support system. After passing through the mounting frame 2 and the hanging frame 3, the inner and outer sides are clamped by the threaded heads 11, the mosaic plates 10 and the fixing nuts 12; the mosaic plates 10 increase the force-bearing area to prevent the surface deformation of the mounting frame 2. The pre-tightening force of the fixing nuts 12 makes the inner side of the support columns 9 press against the inner wall of the channel steel 1 to form a rigid support structure, thereby improving the overall anti-overturning ability.

[0018] See also Figure 1 and Figure 7 As shown, the bottom of the mounting frame 2 is fixedly connected to a connecting frame 13, the upper part of the connecting frame 13 is fixedly connected to a winding device 14, the left side of the connecting frame 13 is fixedly connected to a driving motor 15, the rotating shaft of the driving motor 15 is fixedly connected to the rotating shaft of the winding device 14, and a circular groove 1301 is provided in the middle of the bottom end of the connecting frame 13, 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 to hang the lamp, and the driving motor 15 drives the winding device 14 to realize automatic retraction and release of the telescopic rope. The circular groove 1301 guides the telescopic rope to avoid deviation during retraction; the hanging height of the lamp can be accurately adjusted through motor control, without the need for manual climbing operation, thereby improving installation safety and efficiency, and is suitable for dynamic adjustment of lamp height in high-altitude steel frame scenes.

[0019] See also Figure 1 and Figure 4 As shown, the middle part of the outer side of the hanging frame 3 is fixedly connected with a rotating seat 5, and the inner end of the threaded column 4 is rotatably connected to the inner side of the rotating seat 5. The rotating seat 5 provides a rotating support point for the threaded column 4, so that the threaded column 4 maintains coaxiality during the adjustment process, avoiding thread wear due to eccentric force; 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 move horizontally during rotation, ensuring the smoothness of the adjustment action and reducing the difficulty of installation operation.

[0020] See also Figures 1-4 As shown, a first fixing sleeve 203 is provided in the middle and lower parts of the left and right sides of the mounting frame 2, and a second fixing sleeve 303 is provided in the middle and lower parts of the outer side of the hanging frame 3. A spring 6 is provided between the first fixing sleeve 203 and the second fixing sleeve 303. The spring 6 connects the first fixing sleeve 203 and the second fixing sleeve 303 to form an elastic buffer structure. When the steel frame is vibrated, the compression and extension of the spring 6 can absorb the vibration energy and reduce the rigid impact between the mounting frame 2 and the hanging frame 3; the pre-tightening force of the spring 6 can help maintain the position of the hanging frame 3, prevent the threaded column 4 from loosening due to vibration, and improve the seismic resistance of the structure.

[0021] See also Figure 3 As shown, sliding protrusions 301 are provided on the front and rear sides of the bottom of the hanging frame 3, and the middle parts of the sliding protrusions 301 are rotatably connected to rollers 302. Sliding grooves 201 are provided on the left and right sides of the front and rear ends of the bottom of the mounting frame 2, and the rollers 302 are respectively connected to the inner sides of the corresponding sliding grooves 201 in a rolling manner. The combination of the sliding protrusions 301 and the rollers 302 converts sliding friction into rolling friction, thereby reducing the sliding resistance of the hanging frame 3 on the mounting frame 2 by more than 70%; the rollers 302 roll in the sliding grooves 201, allowing the hanging frame 3 to fine-tune its position laterally, thereby facilitating alignment with the installation position of the channel steel 1 and improving installation accuracy and convenience.

[0022] See also Figure 2-Figure 6As shown, the bottom of the mounting bracket 2 is fixedly connected with a first adsorption magnet 204, which is adsorbed on the bottom of the I-shaped channel steel 1. The bottom of the clamping bracket 8 is at the same level as the upper part of the I-shaped channel steel 1. The bottom of the clamping bracket 8 is fixedly connected with a second adsorption magnet 16, which is adsorbed on 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 to form an auxiliary fixing structure; magnetic adsorption can achieve pre-positioning before mechanical fixation to prevent the mounting bracket 2 from falling, and at the same time enhance the pull-out resistance of the overall connection; the upper and lower magnets cooperate with mechanical clamping to form a double insurance mechanism of "magnetic pre-fixation + mechanical strong locking".

[0023] See also Figure 1-Figure 7 As shown, the mounting frame 2 is an inverted U-shaped structure, and the hanging frame 3 is a 7-shaped structure. Both the mounting frame 2 and the hanging frame 3 are made of stainless steel and are provided with an anti-rust coating on the surface. The structural design of the inverted U-shaped mounting frame 2 and the 7-shaped hanging frame 3 conforms to the mechanical bending moment distribution and can effectively disperse the stress generated by the lamp load; the 304 stainless steel material with the anti-rust coating enables the structure to maintain corrosion resistance in harsh environments such as moisture and dust. Salt spray tests show that the anti-rust life can reach more than 5 years, reducing maintenance costs. The inner side of the hanging frame 3 is matched with the outer edge shape of the I-shaped channel steel 1, and the inner end of the support column 9 is abutted against the inner side of the I-shaped channel steel 1. Rubber pads are provided on 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 matching design of the inner side of the hanging frame 3 and the edge of the channel steel 1 makes the fit degree reach more than 95% during hanging, reducing the installation gap; the support column 9 abuts the inner side of the channel steel 1, and the buffering effect of the rubber pad not only enhances the friction to prevent sliding, but also avoids damage to the channel steel surface caused by rigid contact; the rubber pad also acts as an insulator to prevent static electricity generated by metal friction.

[0024] See also Figure 1-Figure 7 As shown, the inner end surface of the support column 9 is provided with anti-skid lines, which abut against the inner walls of the perforations of the mounting frame 2 and the hanging frame 3 to enhance the friction between the support column 9 and the mounting frame 2 and the hanging frame 3; See also Figure 1-Figure 7 As shown, the outer end face of the threaded column 4 is provided with a rotating handle and a hexagonal drive groove. The hexagonal drive groove is adapted to a wrench or screwdriver tool to facilitate the rotation adjustment of the threaded column 4. The anti-slip texture adopts a serrated design with a surface roughness of Ra = 6.3 μm, which increases the friction coefficient between the support column 9 and the inner wall of the perforation to 0.8, effectively preventing the support column 9 from axial movement during vibration; the texture structure also increases the contact area, so that the torsional stiffness of the support column 9 is increased by 30%, ensuring the connection stability during long-term use.

[0025] The implementation principle of the embodiment of the present application is as follows: first, the upper part of the 7-shaped hanging frame 3 is hung on the left and right side edges of the I-shaped channel steel 1, and the initial positioning is achieved by using the fitting design of the inner side of the hanging frame 3 and the outer edge of the I-shaped channel steel 1. The sliding protrusion 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. Then, the rotating handle on the outside of the threaded column 4 is turned or the hexagonal drive groove is used to adjust the position. Use the tool to rotate, and the threaded column 4 is pushed inward through the threaded sleeve 203, and its inner end is pressed against the rotating seat 5, pushing the hanging frame 3 to move in the direction of the I-shaped channel steel 1 until the upper part of the hanging frame 3 is close to the I-shaped channel steel 1, and the clamping frame 8 is rotated to make the clamping protrusion 801 clamp into the clamping groove 304, forming a 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-slip texture of its inner end face abuts against the hole wall to increase friction and support The threaded head 11 at the outer end of the column passes through the inner interlocking plate 10 and the mounting bracket 2 in sequence, and is tightened with the fixing nut 12 to fix the mounting bracket 2 and the hanging bracket 3. The rubber pad on the inner side of the I-shaped channel steel 1 passes through the support column to play a buffering and anti-slip 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 bracket 3 to alleviate the vibration after installation. The first adsorption magnet 204 at the bottom of the mounting bracket 2 is adsorbed on the bottom of the channel steel, and the second adsorption 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, and the structural stability is further enhanced by magnetic force. Finally, the connecting frame 13 is fixed to the bottom of the mounting frame, and the winding device 14 is located on the upper part of the connecting frame 13. The driving motor 15 drives the winding device shaft to rotate. The lamp is hung on the bottom end of the telescopic rope of the winding device 14. The winding device is retracted and released by the driving motor 15 in forward and reverse rotation. The telescopic rope passes through the circular groove 1301 at the bottom end of the connecting frame to achieve precise adjustment of the lamp height.
