Problems solved by technology

[0003] Because the mechanical stability of the ladder bridge is weaker than that of the pallet bridge, and the connection between the ladder and the ladder side is generally a point connection, its stability, earthquake resistance and bearing capacity are not good.

Embodiment Construction

[0016] As shown in the figure, there is a kind of ladder for ladder bridge. The ladder is an integral plate with Ω-shaped longitudinal section, wherein, the two ends of ladder 2 are vertically upwardly provided with baffles 1, and the longitudinal section of baffle 1 is at right angles. Trapezoidal, one end at a right angle is connected to the ladder 2; the height h of the baffle plate 2 is 5-10 cm, and its outer surface is covered with a layer of buffer pad 3, and the thickness of the buffer pad is 2-15 mm. Simultaneously, the bottom surface of the ladder 2 is evenly provided with some installation holes 4, and the length of the installation holes is 16cm, and the width is 8.5cm.

[0017] The beneficial effects of the present invention are:

[0018] 1. Since the longitudinal section of the ladder is an Ω-shaped integral plate, the connection between the ladder side and the ladder is changed from the traditional point contact to the surface contact, which increases the contact...

Abstract

The invention relates to a high-strength horizontal bar for ladder type cable trays. The longitudinal section of the horizontal bar is an omega-shaped integral plate. Stop plates are vertically disposed at two ends of the horizontal bar. The longitudinal section of each stop plate is in the shape of a right trapezoid, and one right-angle end of every stop plate is connected with the horizontal bar. The longitudinal section of the horizontal bar is the omega-shaped integral plate, so that ladder sides are connected with the horizontal bar by means of face contact instead of traditional point contact, the contact area is larger, cold solder joint can be controlled effectively, welding can be output quickly with high quality, and shock strength is higher.

Description

technical field [0001] The invention relates to a ladder bar for a ladder bridge, belonging to the technical field of cable laying equipment. Background technique [0002] Cable trays are widely used in petroleum, chemical, electric power, light industry and other industries. They are mainly used for laying overhead power cables, control cables, lighting lines, and telecommunication cables. The bridge frame includes ladder sides and ladder knuckles, and the ladder sides and ladder knuckles are fixed as a whole. Usually, the cross-sectional shape of the ladder side profiles of the cable tray is changed to improve the strength, bearing capacity and bending resistance of the bridge frame. [0003] Since the mechanical stability of the ladder bridge is weaker than that of the pallet bridge, and the connection between the ladder and the ladder side is generally a point connection, its stability, earthquake resistance and bearing capacity are not good.
