Description
Technical field
The present invention relates to a kind of device that carries overhead cable, particularly a kind of Integral ladder type cable tray that adopts one time punching molded technology processing.
Background technique
Cable testing bridge system is the class staple product in manufacturing industry, is the main equipment for specification, protection cable and electric transmission line safety in each infrastructure project.At present, traditional ladder-type cable bridge is to adopt two terraced limits and cross-arm to form mostly, between two terraced limits and cross-arm, conventional means of fixation has riveted joint, grafting or welding, because the intensity of riveted joint and the carrying of pegging graft is limited, steadiness is poor, therefore the means of fixation between two terraced limits and cross-arm adopts the mode of welding to fix conventionally, discharges a large amount of CO when crane span structure welding
2deng harmful gas, environment is caused to certain pollution, simultaneously, because of the existence of welding procedure, will inevitably there is zinc-plated rear local acid returning phenomenon, cause the anticorrosion grade of soldering point to decline, so, the welding antiseptic power of product is poor, in humidity and the strong environment of corrosivity, very easily gets rusty, and especially in ocean environment, shows more obviously.In addition, welded structure is because part is more, and docking port and solder joint cause crane span structure integrated carrying ability to decline, and only has the requirement that can meet bearing capacity in the situation of the thickness that increases crane span structure sheet material, not only serious waste limited resource, do not meet the requirement of national energy-saving consumption reduction; And increased the deadweight of crane span structure, increase especially the deadweight of supporting environment.
Summary of the invention
The object of the present invention is to provide the Integral ladder type cable tray that a kind of intensity is high, corrosion resistance is strong, adapt to humidity and the particular/special requirement of the strong environment of corrosivity to crane span structure.
For achieving the above object, the technical solution used in the present invention is: Integral ladder type cable tray, comprise two terraced limit and cross-arms, this ladder limit and cross-arm are that monoblock plate stamping is made, described cross-arm is provided with flute profile stiffening rib, the Y-shaped bifurcated in two ends of this flute profile stiffening rib, in this flute profile stiffening rib, cross section is trapezoidal, and this trapezoidal faces is provided with some horizontal long-round-shape mounting holes.
The present invention adopts monoblock plate stamping to make, without welding, the environmental pollution of having avoided welding procedure to cause, improve the antiseptic power of product, reduce the impact of welding on crane span structure sheet material stress, the stiffening rib that middle part is flute profile is set simultaneously on cross-arm, improve the integrated carrying ability of crane span structure, the two ends Y shape bifurcated of flute profile stiffening rib has not only increased the surface of contact on cross-arm and terraced limit, disperse stressed surface of contact, and improve the bearing strength of cross-arm, do not need just can meet in the situation by increasing crane span structure section bar thickness the requirement of load-bearing cable, the needs in environment moist and that corrosivity is strong are met completely.Especially in ocean environment, show more obviously.
The bottom on described terraced limit is L shaped structure, and forms stiffening rib.
The stiffening rib of the L shaped structure of ladder limit bottom can limited raising crane span structure bulk strength.
The top on two described terraced limits is provided with inverted U-shaped.
Inverted U-shaped on ladder limit can improve the intensity on terraced limit on the one hand, can avoid on the other hand scratching the cable being laid on crane span structure.
The root outer rim at described flute profile stiffening rib middle part is provided with the reverse reinforced block of at least one pair of along cross-arm longitudinal direction.
Oppositely reinforced block is equivalent to increase reverse reinforcement in the root both sides at flute profile stiffening rib middle part, improves stability and the bearing strength of crane span structure.
Described terraced limit is provided with some radiation holes, and this radiation hole longitudinally arranges along terraced limit.
The deadweight of fixing and reduce crane span structure when radiation hole is installed for crane span structure.

Embodiment
Below in conjunction with accompanying drawing, technological scheme of the present invention is described in detail.
Embodiment one:
As Figure 1-Figure 5, Integral ladder type cable tray of the present invention, comprises two terraced limits 1 and cross-arm 2, and this ladder limit 1 and cross-arm 2 are made for monoblock plate stamping, and sheet material can adopt carbon steel, stainless steel, aluminum alloy etc. can meet the sheet material of requirement of strength.Cross-arm 2 is provided with flute profile stiffening rib 3, and when the Y-shaped bifurcated in the two ends of this flute profile stiffening rib 3, stressed more even, intensity is higher; In flute profile stiffening rib 3, cross section is trapezoidal, and the end face of this flute profile stiffening rib or bottom surface are provided with some horizontal long-round-shape mounting holes 4.The protrusion direction of flute profile stiffening rib 3 can form convex stiffening rib upward, and now, long-round-shape mounting hole site, on the end face of flute profile stiffening rib, also can form spill stiffening rib down, and now long-round-shape mounting hole 4 is positioned on the bottom surface of flute profile stiffening rib.
Integral ladder type cable tray of the present invention adopts monoblock plate stamping to make, without welding, the environmental pollution of having avoided welding procedure to cause, improve the antiseptic power of product, reduce the impact of welding on crane span structure sheet material stress, the stiffening rib that middle part is flute profile is set simultaneously on cross-arm, improve the integrated carrying ability of crane span structure, especially the Y shape bifurcated at flute profile stiffening rib two ends has not only increased the surface of contact on cross-arm and terraced limit, disperse stressed surface of contact, and improve the bearing strength of cross-arm, do not need just can meet in the situation by increasing crane span structure section bar thickness the requirement of load-bearing cable.
Embodiment two
In Practical Project uses, in order to prevent the intensity unstability of cross-arm 2 in the time bearing large cable, further improve the bearing capacity of cross-arm 2; On cross-arm 2, the middle part root outer rim of flute profile stiffening rib 3 is along being provided with at least one pair of reverse reinforced block 5 on cross-arm 2 longitudinal directions.Oppositely reinforced block 5 is equivalent to increase reverse reinforcement in the both sides of flute profile stiffening rib, improves stability and the bearing strength of crane span structure.
