Description

Technical Field

[0001] The utility model relates to the technical field of galvanized bridge frames, in particular to a high-strength supporting galvanized bridge frame. Background Art

[0002] Galvanized cable tray is a metal structure used to support and protect cables. It is made of galvanized steel plate and processed and surface treated through certain processes to enhance its corrosion resistance and mechanical strength. Galvanized cable tray is widely used in cable wiring systems in industrial, commercial and civil buildings.

[0003] For example, a Chinese patent discloses: a shockproof galvanized bridge frame, patent announcement number: CN219041285U, which forms a double-layer structure by adding a U-shaped plate inside the bottom groove. The U-shaped plate slides in the sliding groove using sliding blocks on both sides, and the buffer at the bottom is used to alleviate the buffering of the U-shaped plate when it is shocked. While maintaining the balance inside the bottom groove, the shockproof effect is improved. The overall structure is simple and easy to operate.

[0004] However, during the implementation of the above technical solution, it was found that there are at least the following technical problems: the above device clamps and fixes the cable by squeezing the cable clamp to deform during cable installation, but the clamping method of squeezing the cable clamp to deform will cause material fatigue over a long period of use, resulting in a weakening of its fixing force, requiring frequent replacement or maintenance, and increasing the risk of cable loosening or displacement.

[0032] Working principle:

[0033] The first step is to install the cable in the galvanized bridge frame body 11. The galvanized bridge frame body 11 supports and protects the cable, keeps the cables neatly arranged, and facilitates management and inspection. When the cable is installed, the cable is pressed into the two clamping blocks 14, and the cable squeezes the clamping blocks 14 to slide on both sides. When the clamping blocks 14 slide, they slide in the slide groove 15 through the slider 16 to improve the stability during sliding, and when the clamping blocks 14 slide, the rotating rod 12 is driven to rotate through the connecting rod 13, and the rotating rod 12 synchronously drives the other clamping block 14 to slide through another connecting rod 13 to ensure the synchronization of the two clamping blocks 14. After the cable is pressed down, the reset spring 17 drives the clamping block 14 to slide and reset through the slider 16 to clamp and fix the cable. When the cable is installed, the clamping block 14 slides in the slide groove 15 through the slider 16, and there is no need to squeeze the clamping block 14 to produce deformation to clamp and install the cable, which is beneficial to prolonging the service life of the device, saving the number of replacements, and improving the practicality of the device.

[0034] In the second step, after the cable installation is completed, the cover plate 18 is slid into the galvanized bridge frame body 11 to achieve shielding and protection of the cable, and the rubber pad 21 can be slid into the positioning block 19. The rubber pad 21 is used to protect the corners of the cover plate 18 to prevent cuts to the staff during installation and maintenance, thereby improving the safety of construction and maintenance. When the galvanized bridge frame body 11 is fixedly installed, the support rod 27 can be pulled to slide. When the support rod 27 slides, it rotates in the rotating block 25 through the second rotating shaft 26, and the rotating block 25 rotates outside the connecting block 23 through the first rotating shaft 24. When the support rod 27 slides, it pushes the rotating block 25 to rotate and shrink the horizontal occupied space. The placement height is adjusted by sliding the support rod 27, and the pin 29 is nailed down to provide high-strength support for the galvanized bridge frame body 11. The installation height of the pin 29 can be adjusted by the sliding support rod 27, and the angle during installation can be adjusted by rotating the connecting seat 28 to adapt to different installation environments and improve the adaptability of the device.

[0035] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
