Description
Technical field
The utility model relates to a kind of hull topside segment folding operation cage device.
Background technology
At present each ship enterprise general-duty high-altitude operation platform when building berth or dock carry the segmentation of hull topside has the scaffold of landing, scaffold cradle, high-altitude lift car, mechanical elevating cage these is several.These facilities use extensively, but certain deficiency is arranged.The scaffold that lands begins to be provided with scaffold from ground, set up to the high-altitude by lower, have the place that needs that pedal is set in construction then, need in the erection process to spend more material and man-hour, need take bigger place, transportation, loading and unloading and place carrying cost are bigger.It is dangerous that aloft work is set up and dismantled to scaffold cradle, and the job platform stability of being put up simultaneously is not good enough.The high-altitude lift car is higher to place and requirement for height, limited building berth/dock space inner machine can easily not adjusted the location, turns round, lifting, stability is bad, generally be used to investigate on the spot engineering, spraying operation, be not suitable for the high-altitude construction operation of big work capacity, the machine price is expensive, and the equipment daily attention is had relatively high expectations.The mechanical elevating cage needs long continuous square body between deck space for its installation, and price is more expensive, and the equipment daily attention is had relatively high expectations.
The utility model content
Problem to be solved in the utility model is: at the problem of above-mentioned existence provide that a kind of dismounting is safe and efficient, low cost of manufacture, hull topside segment folding operation cage device that floor area is little.
The technical scheme that the utility model adopted is: a kind of hull topside segment folding operation cage device is provided, it is characterized in that: comprise that overlap joint is hung arm and the cage of constructing, described construction cage is fixedly mounted on the bottom that described overlap joint is hung arm, the side that described overlap joint is hung arm is provided with and hangs the joint welding plate of taking the hull topside, and described construction cage is one to be provided with two-layered steel plates net flat-bed cuboid framework at least.
Preferably, described expanded metal lath flat-bed floor height is at 1.8～2.0 meters, and it highly makes things convenient for personnel to stand.
Further, between two-layer described expanded metal lath platform, also be provided with vertical ladder up and down.
Preferably, the described vertical ladder up and down of adjacent layer is a left and right sides alternative arrangement, the weight overbalance that causes in the crawling process in avoiding.
Further, on the non-construction side of described construction cage, also be provided with the safety net that surrounds described construction cage, to increase safety.
Further, the construction surface at the construction cage is provided with every empty support.
Compared with prior art, the hull topside segment folding operation that the utility model provides is with the beneficial effect of cage device: make package unit before segment carrying in advance, only need direct joint welding on deck/platform in building berth/dock segment carrying stage, can accelerate the speed of setting up of high-altitude operation platform, and dismounting is quick, can shorten time on building berth; Unit-modularized use, clashing and breaking are less, and daily attention is simple, and operating cycles is longer; Simple in structure, be easy to make, main body adopts solid drawn pipe to make, and the material quantity of only 1.3 tons of weight, Stability Analysis of Structures, use is less, reduces making, transportation, loading and unloading and handling cost; It is less to take up room, and helps turnover and personnel's site operation that height drives to wait other main equipment, is convenient to launch construction surface; Integral unit is gone on board, and handling is convenient, has avoided setting up on the ship high-altitude danger of job platform; Erection mode is according to the production actual conditions, only is provided with in the place of needs, has avoided the blindness of construction, reduces manpower/material resources that high-altitude operation platform sets up required consumption.
