Description

Technical Field

[0001] The utility model belongs to the technical field of cable bridges, in particular to a novel reinforced riveted ladder crossbar. Background Art

[0002] The ladder cable tray is a ladder-shaped assembly (referred to as ladder rack) composed of side panels and cross arms (ladder cross) fixed to the side panels by welding. The ladder cable tray also has the advantages of light weight, low cost, easy installation, good heat dissipation and ventilation, so it is usually used in open wiring systems in industrial and civil buildings.

[0003] Traditional simple flat ladder crossbars are formed by four bendings on a bending machine, which has low production efficiency and complicated production process. Secondly, most of the cable tray industry currently still uses hot-dip galvanized sheet materials for production and processing. The ladder-type cable tray is assembled by welding the crossarms and side plates. During welding, the sensitivity of welding cracks and pores increases, zinc evaporates and smoke, oxide inclusions and the galvanized layer melt and are destroyed. When the zinc layer is destroyed by welding, rust will appear at the welding position, and the crossarm welding will gradually fall off due to severe corrosion of the side plates and crossarms.

[0004] In view of this, a new type of reinforced riveted ladder crossbar is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a novel reinforced riveted ladder rung in order to solve the above-mentioned problems.

[0006] The technical solution adopted by the utility model is as follows: a novel reinforced riveted ladder cross, comprising a bridge ladder cross, the bridge ladder cross comprising a ladder cross body, the two ends of the ladder cross body being bent in a direction away from each other to form reinforcing ribs;

[0007] Two ends of the bottom of the ladder cross body are bent to form horizontal installation edges.

[0008] In a preferred embodiment, the middle portion of the upper end of the ladder cross body is also bent inward to form a second reinforcing rib.

[0009] In a preferred embodiment, the second reinforcing rib and the reinforcing rib are both arched.

[0010] In a preferred embodiment, the bridge ladder crosspiece is entirely made of hot-dip galvanized steel plate.

[0011] In a preferred embodiment, the reinforcing rib, the second reinforcing rib and the mounting edge are all formed by cold bending.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0013] 1. In the utility model, reinforcing ribs are designed on the three surfaces of the ladder cross body to improve the load-bearing capacity of the cross arm and improve the NVH performance. It breaks through the traditional method of increasing the load strength of the ladder cross by the thickness of the steel plate. While saving materials, it can also optimize and improve the quality, so that it can better protect the cables laid in the bridge.

[0014] 2. In the utility model, horizontal mounting edges are provided at both ends of the ladder cross body. When combined with the side panels, the ladder cross and the side panels can be combined together by self-piercing riveting process, which replaces the traditional welding fixing method, is more environmentally friendly and safe, and will not cause the side panels and cross arms to fall off due to corrosion.

[0015] 3. In the utility model, the whole is formed in one step by adopting the cold bending automatic production line, which requires fewer operators, has high production efficiency, stable product quality and high automation degree. BRIEF DESCRIPTION OF THE DRAWINGS
