A highly impact-resistant anti-corrosion aluminum alloy cable tray

Abstract

The present invention discloses an anti-corrosion aluminum alloy bridge with high impact resistance, which includes a bridge trough body, reinforcing ribs, a reinforced bottom plate and assembly columns. The bridge trough body is a trough body integrally formed of aluminum alloy. Two trapezoidal pressing grooves are symmetrically arranged at the bottom of the bridge trough body. An outer edge plate is arranged outward at the top of the bridge trough body. Ventilation holes are arranged on the bottom plate of the bridge trough body between the two trapezoidal pressing grooves. The reinforcing ribs are C-shaped channel steel reinforcing ribs made of aluminum alloy, and the reinforcing ribs are distributed outside both sides of the bridge trough body with the openings facing inward. The top of the reinforcing ribs is connected to the bottom of the outer edge plate. The reinforced bottom plate is a shallow trough-shaped bottom plate integrally formed of aluminum alloy. The present invention strengthens the anti-torsion and folding strength of both sides and the bottom surface of the trough body through the reinforcing ribs and the reinforced bottom plate. Through the desiccant and ventilation holes in the drying cavity, the water vapor generated inside the bridge placed outdoors or by the sea is absorbed to prevent the bridge from being corroded.

Description

Technical Field

[0001] The present invention belongs to the technical field of cable trays, and particularly relates to an anti-corrosion aluminum alloy cable tray with high impact resistance. Background Art

[0002] A cable tray is a bracket used to support and place cables. The cable tray includes a trough for accommodating cables and a cover plate.

[0003] Due to its own requirements, most cable trays are made of metal to ensure their strength. However, usually the trough of the cable tray is only formed by directly bending a metal plate, but the strength of the trough formed by direct bending is not high. If it is near the sea or in a corrosion area, the material must have anti-corrosion and moisture resistance. The combined cable tray is suitable for the laying of various projects, units, and various cables. It has the characteristics of simple structure, flexible configuration, convenient installation, and novel form. The existing combined cable trays have single functions, poor impact resistance, and are prone to internal cable pulling. The combined cable trays are prone to deformation, affecting their service life. Summary of the Invention

[0004] The purpose of the present invention is to solve the above deficiencies of the prior art, and proposes an anti-corrosion aluminum alloy cable tray with high impact resistance, which includes a cable tray trough, reinforcing ribs, a reinforcing bottom plate, and assembly columns. The cable tray trough is an integrally formed aluminum alloy trough. Two trapezoidal grooves are symmetrically arranged at the bottom of the cable tray trough. An outer edge plate is provided outward at the top of the cable tray trough. Vent holes are provided on the bottom plate of the cable tray trough between the two trapezoidal grooves. The reinforcing ribs are C-shaped channel steel reinforcing ribs made of aluminum alloy, and the openings of the reinforcing ribs face inward and are distributed outside both sides of the cable tray trough. The top of the reinforcing ribs is connected to the bottom of the outer edge plate. The reinforcing bottom plate is a shallow trough-shaped bottom plate integrally formed of aluminum alloy. An inner edge plate is provided inward at the top of the reinforcing bottom plate. The bottom of the reinforcing bottom plate is connected to the bottom of the trapezoidal groove of the cable tray bottom plate and the bottom of the reinforcing ribs. An opening is provided on the inner edge plate at the overlapping part of the inner edge plate and the reinforcing ribs. The outside of the reinforcing ribs is connected to the opening of the inner edge plate.

[0005] Furthermore, the trapezoidal groove and the reinforcing bottom plate are connected by rivets.

[0006] Furthermore, assembly columns are provided at the four corners of the cable tray trough passing through the reinforcing ribs.

[0007] Furthermore, the vent holes are evenly arranged in an array at the bottom of the cable tray trough.

[0008] Furthermore, the reinforcing ribs are equidistantly arranged on both sides of the cable tray trough.

[0009] Furthermore, the reinforcing ribs are connected to the cable tray bottom plate and the reinforcing bottom plate by spot welding.

[0010] Furthermore, a drying cavity is formed between the reinforcing bottom plate and the bottom of the bridge frame groove through trapezoidal pressing grooves, and a desiccant is provided in the drying cavity.

[0011] Beneficial effects:

[0012] The torsional resistance and folding strength of the two sides and the bottom surface of the groove body are enhanced through the reinforcing ribs and the reinforcing bottom plate. Through the desiccant and air holes in the drying cavity, the water vapor generated inside the bridge frame when placed outdoors or by the sea is absorbed to prevent corrosion of the bridge frame.

[0016] To deepen the understanding of the present invention, the present invention will be further described in detail below in combination with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation to the protection scope of the present invention.

[0017] Embodiment example:

[0018] A high-impact-resistant anti-corrosion aluminum alloy bridge frame includes a bridge frame groove body, reinforcing ribs, a reinforcing bottom plate and assembly columns. The bridge frame groove body is a groove body integrally formed of aluminum alloy. Two trapezoidal pressing grooves are symmetrically provided at the bottom of the bridge frame groove body. An outer edge plate is provided outward at the top of the bridge frame groove body. Air holes are provided on the bottom plate of the bridge frame groove body between the two trapezoidal pressing grooves. The reinforcing ribs are C-shaped channel steel reinforcing ribs made of aluminum alloy. The reinforcing ribs are distributed outside the two sides of the bridge frame groove body with the openings facing inward. The top of the reinforcing ribs is connected to the bottom of the outer edge plate. The reinforcing bottom plate is a shallow groove-shaped bottom plate integrally formed of aluminum alloy. An inner edge plate is provided inward at the top of the reinforcing bottom plate. The bottom of the reinforcing bottom plate is connected to the bottom of the trapezoidal pressing groove of the bridge bottom plate and the bottom of the reinforcing ribs. An opening is provided in the overlapping part of the inner edge plate and the reinforcing ribs. The outside of the reinforcing ribs is connected to the opening of the inner edge plate.

[0019] As Figure 1 、 2 shown;

[0020] First, bend the aluminum alloy steel plate to form the bridge trough 1, the reinforcing rib 2 and the reinforcing bottom plate 3 through bending. Punch holes at the bottom of the bridge trough 1. Fix the reinforcing rib 2 to both sides of the bridge trough 1 by welding. Cut the inner edge plate of the reinforcing bottom plate 3 according to the position of the reinforcing rib 2, and then weld the inner edge plate to the outside of the bridge trough 1 and the reinforcing rib 2 by welding. Connect the trapezoidal press groove at the bottom of the bridge trough 1 and the surface where the reinforcing bottom plate 3 is connected with rivets 5. Finally, fill the drying cavity formed by the reinforcing bottom plate 3 and the bridge trough 1 with desiccant.

[0021] When the bridge needs to be installed, install the assembly columns 4 at the reinforcing ribs 2 at the four corners of the bridge, and install the bridge through the assembly columns 4.
