DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figure 1 - Figure 3 , the present utility model provides a technical solution: a hot-dip galvanized ladder-type large-span bridge, including a first side plate 1, a lower cross beam 5 is fixedly installed on the side wall of the first side plate 1, and a downward pressing and clamping mechanism is fixedly installed on the inner wall of the end of the lower cross beam 5 away from the first side plate 1;

[0023] The downward pressing and clamping mechanism includes a fixed block 15 fixedly installed on the inner wall of the end of the lower cross beam 5, a connecting column 16 is fixedly installed on the inner wall of the fixed block 15, a sliding column 17 is fixedly installed on the top of the connecting column 16, a clamping ring 18 is slidably installed on the outer wall of the sliding column 17, a clamping plate 19 is fixedly installed on the top of the sliding column 17, a clamping block 10 is sleeved on the outer wall of the clamping plate 19, a chute 12 is opened on the inner wall of the clamping block 10, a spring 14 is fixedly connected to the inner wall of the chute 12 away from the clamping block 10, and a clamping head 13 is fixedly connected to the end of the spring 14 away from the chute 12.

[0024] It should be noted that: only by pressing down the upper cross beam 4, the clamping block 10 will slide along the sliding column 17, and under the elastic force of the spring 14, the clamping head 13 will be clamped into an appropriate position of the clamping plate 19, so as to realize the fixation of the cable.

[0025] Please refer to Figure 1 , the present utility model provides a technical solution: a hot-dip galvanized ladder-type large-span bridge, including a clamping block 10 with a clamping groove 11 opened on its inner wall, and the inner wall diameter of the clamping groove 11 is equal to the outer wall diameter of the clamping plate 19.

[0026] It should be noted that: when the clamping block 10 is sleeved on the clamping plate 19, the gap between the two is very small, thus realizing a tight connection, which helps to enhance the stability of the cable fixation and prevent the cable from loosening or falling off on the bridge.

[0027] Please refer to Figure 2 , the present utility model provides a technical solution: a hot-dip galvanized ladder-type large-span bridge, including an upper cross beam 4 fixedly installed on the outer wall of the clamping block 10, and a rotating shaft 7 is rotatably installed at the bottom of the end of the upper cross beam 4 away from the clamping block 10, and the outer wall of the rotating shaft 7 is fixedly installed on the top outer wall of the lower cross beam 5.

[0028] It should be noted that: through the rotational connection between the upper crossbeam 4 and the lower crossbeam 5, that is, the setting of the rotating shaft 7, the assembly process of the bridge frame becomes more flexible and convenient. Users can connect the upper crossbeam 4 and the lower crossbeam 5 according to actual needs to form a complete bridge frame structure.

[0029] Please refer to Figure 2 - Figure 3 For this, the present utility model provides a technical solution: a hot-dip galvanized ladder-type large-span bridge frame, including a second side plate 6 fixedly installed at one end of the lower crossbeam 5 away from the first side plate 1, and the second side plate 6 is parallel to the first side plate 1.

[0030] It should be noted that: the second side plate 6 and the first side plate 1 being parallel can form a more stable frame structure, enhancing the overall stiffness of the bridge frame, enabling it to better bear loads such as cables, and ensuring the stability and safety of the bridge frame during long-term operation.

[0031] Please refer to Figure 2 For this, the present utility model provides a technical solution: a hot-dip galvanized ladder-type large-span bridge frame, including an upper arc-shaped groove 8 opened at the bottom surface of the center of the upper crossbeam 4, and a lower arc-shaped groove 9 opened at the top surface of the center of the lower crossbeam 5.

[0032] It should be noted that: the upper arc-shaped groove 8 opened at the bottom surface of the center of the upper crossbeam 4 and the lower arc-shaped groove 9 opened at the top surface of the center of the lower crossbeam 5 cooperate with each other, which can provide a more fitting support surface for the cable. This arc-shaped design can better adapt to the shape of the cable, making the cable more stable when fixed and not easy to loosen or slip.

[0033] Please refer to Figure 3 For this, the present utility model provides a technical solution: a hot-dip galvanized ladder-type large-span bridge frame, including a connecting plate 2 fixedly installed on the side wall of the first side plate 1 away from the lower crossbeam 5, and a bolt 3 is threadedly connected to the surface of the connecting plate 2.

[0034] It should be noted that: through the cooperation of the connecting plate 2 and the bolt 3, the first side plate 1 can be conveniently connected to other components or structures. This threaded connection method is not only simple to operate but also firmly connected, which can effectively improve the installation efficiency of the bridge frame.

[0035] Please refer to Figure 1 - Figure 3 For this, the present utility model provides a technical solution: a hot-dip galvanized ladder-type large-span bridge frame, including that the materials of the first side plate 1, the upper crossbeam 4, the lower crossbeam 5, and the second side plate 6 are aluminum alloy, and a galvanized layer is provided on the surface of the aluminum alloy.

[0036] It should be noted that: As a lightweight and high-strength material, aluminum alloy has excellent mechanical properties and corrosion resistance. Selecting aluminum alloy as the material for the side plate 1, the upper cross beam 4, the lower cross beam 5, and the side plate 2 can ensure that the cable tray has sufficient strength and stability when bearing loads such as cables, while reducing the overall weight of the cable tray, facilitating installation and transportation;

[0037] Furthermore, the galvanized layer provided on the surface of the aluminum alloy further enhances the corrosion resistance of the cable tray. The galvanized layer can effectively isolate the contact between the aluminum alloy and corrosion factors such as oxygen and moisture in the external environment, thereby extending the service life of the cable tray.

[0038] Please refer to Figure 2 , the present utility model provides a technical solution: a hot-dip galvanized ladder-type large-span cable tray, including rubber pads are provided on the surfaces of the upper arc groove 8 and the lower arc groove 9, and anti-slip lines are integrally formed on the surfaces of the rubber pads.

[0039] It should be noted that: The rubber pad has good elasticity and softness, and can provide better support and protection for the cable. When the cable is placed between the upper arc groove 8 and the lower arc groove 9, the rubber pad can buffer the direct contact between the cable and the groove body, reduce friction and wear, thereby extending the service life of the cable and the cable tray;

[0040] Furthermore, the setting of the anti-slip lines further enhances the stability of the cable in the upper arc groove 8 and the lower arc groove 9, increases the friction between the cable and the rubber pad, prevents the cable from sliding or shifting on the cable tray, and ensures the reliable fixation of the cable;

[0041] Furthermore, the rubber pad has a certain compression space, so that the upper cross beam 4 can be unlocked when a downward pressing force is applied again.

[0042] Working principle: When it is necessary to fix the cable, the cable can be placed in the upper arc groove 8 and the lower arc groove 9 of the lower cross beam 5 and the upper cross beam 4. At this time, by pressing down the upper cross beam 4, the clamping block 10 at the bottom of the upper cross beam 4 will slide downward along the sliding column 17. During the sliding process, the spring 14 is compressed, and at the same time, the clamping head 13 moves in the chute 12. When the clamping block 10 slides down to a sufficient position, the elastic force of the spring 14 will push the clamping head 13 to move outward so that it can be clamped into the bottom of the chuck 19, and the upper cross beam 4 is firmly fixed on the lower cross beam 5. At the same time, the cable is also clamped between the two. When maintenance or cable replacement is required, because the rubber pad has a certain compression space, at this time, press down the upper cross beam 4 to make the clamping block 10 continue to move downward. The clamping head 13 will first be clamped into the bottom of the snap ring 18. At this time, lift the upper cross beam 4, and the clamping head 13 will drive the snap ring 18 to move upward synchronously. As the upper cross beam 4 is further lifted, the clamping head 13 will move upward along the bottom arc surface of the snap ring 18 and finally slide back into the chute 12. When the clamping head 13 completely disengages from the chuck 19, the elastic force of the spring 14 will be released again, making the clamping head 13 return to its initial position to prepare for the next clamping operation.
