Abstract
The invention relates to a portable ladder suitable for a large ore carrier. The portable ladder suitable for the large ore carrier comprises ladder columns (1) and ladder steps (2) connected between the ladder columns fixedly; a gib head is arranged on the top of each ladder column; the bottoms of the ladder columns are hinged to a platform (4), and the width of the platform is greater than the distance between the two ladder columns; alternatively, the bottoms of the ladder columns are hinged with a left platform and a right platform respectively, and the left platform and the right platform are correspondingly hinged to the bottoms of the two ladder columns; and the lower ends of the ladder columns are provided with the platforms, during working, the platforms are put down, workers can step on the platforms, and the platforms are turned upwards and folded when not used. The platforms can be fixed on a profile of a carrier body structure and have an effect of fixing the portable ladder, and the workers can climb the portable ladder through the platforms; the portable ladder is convenient to use, and manufacturing cost is not increased; and regardless of the structure of a carrier body, the workers can climb up and down the ladder smoothly. The shortcoming that the weight of the carrier body is increased or construction is troublesome due to two solutions used for increasing the area of platforms in the prior art is overcome.
Description
Technical field
The present invention relates to portable ladder peculiar to vessel, specifically refer to, a kind of portable ladder being applicable to large-scale ore carrier.
Background technology
The ballast tank of large-scale ore carrier is usually larger, uses when portable ladder inspection and does not often have suitable platform to be used for supporting ladder lower end, and have to check that platform is taken in position at each, not only construction is got up pretty troublesome, and also result in certain waste for this reason.
For the wing tank structure of the ore carrier shown in Fig. 1, platform (the arrow indication place) narrower in width of Ship Structure, and width is consistent up and down, staff is difficult to set foot on portable ladder by this platform, therefore portable ladder cannot be used with existing structure, even if one deck platform place hook fixes the gib head on portable ladder ladder top above, ladder lower end still cannot be fixed on lower floor's platform, and at this moment the use angle of ladder is more than 90 degree, that is ladder is in the state tilted laterally, cannot ensure the safety of user at all.
In order to address this problem, prior art has two kinds of approach: the first requires that Ship Structure considers the service condition of portable ladder in advance, the lower floor's platform being used for fixing portable ladder is done wide doing greatly, but can bring the increase of light weight like this, and increase steel for ship structure amount, uneconomical.It two is use the platform place of lower floor of portable ladder to add chain-wales throughout, and be used for fixing portable ladder, in Fig. 2, arrow indication part is the chain-wales of increase.But because fabrication stage of outfititem will be later than Ship Structure, when waiting outfititem to go on board to freeze, the paint of Ship Structure will be destroyed.Present specification has PSPC requirement to ballast tank, and the coating duty amount that welding, repairing destroy is large and loaded down with trivial details, can cause a large amount of doing over again, and incurs loss through delay shipbuilding period, and therefore visible the method is also uneconomical.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of portable ladder being applicable to large-scale ore carrier, is convenient to staff and goes up descending stair smoothly and need not change Ship Structure or increase hull weight.
The technical scheme that the present invention solves the problem is as follows:
Be applicable to a portable ladder for large-scale ore carrier, the top comprising cleat stanchion and be fixed in cleat stanchion described in the step between cleat stanchion is installed with gib head, it is characterized in that:
The bottom-hinged of described cleat stanchion has platform.
Further, in order to alleviate the weight of platform, described platform is two, left and right, and correspondence is hinged on the bottom of two cleat stanchions.
Further, the width of described platform is greater than the distance between two cleat stanchions.
Compared with prior art, beneficial effect of the present invention is:
The present invention carries platform in cleat stanchion lower end, is put down by platform during work, is convenient to staff and stops over and trample, pack up when not needing by platform turns over.The section bar that both platform can be fixed on Ship Structure plays the effect of fixing portable ladder, the platform can climbed as personnel again, easy to use and do not increase manufacturing cost, no matter the structure of hull, the personnel that can realize go up descending stair smoothly.Overcome prior art for increasing platform area and increase hull weight that two kinds of solutions adopting cause or cause the drawbacks such as construction trouble.
Accompanying drawing explanation
Fig. 1 is the limit chamber structure schematic diagram of existing ore carrier.
Fig. 2 is the structural representation (Fig. 1 overlooks direction) of platform other increase chain-wales in FIG.
Fig. 3 is structural representation of the present invention.
Fig. 4 is the lateral view of Fig. 3.
In figure: 1, cleat stanchion; 2, step; 3, gib head; 4, platform.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further detail; the restriction of described embodiment not to invention protection domain; obviously, those of ordinary skill in the art are not needing to obtain other embodiments under the prerequisite paying creative work, and these all belong to protection scope of the present invention.
Shown in composition graphs 3 and Fig. 4, a kind of portable ladder being applicable to large-scale ore carrier, comprise cleat stanchion 1 and be fixed in the step 2 between cleat stanchion, the top of described cleat stanchion is installed with gib head 3, and the bottom-hinged of described cleat stanchion has platform 4.The width of described platform is greater than the distance between two cleat stanchions.
In order to alleviate the weight of platform, described platform can be designed as two, left and right, and correspondence is hinged on the bottom of two cleat stanchions.
The present invention carries platform in cleat stanchion lower end, during work, platform is put down, be convenient to staff stop over and trample, pack up platform turns over when not needing, the section bar that both platform can be fixed on Ship Structure plays the effect of fixing portable ladder, the platform can climbed as personnel again, easy to use and do not increase manufacturing cost, no matter the structure of hull, the personnel that can realize go up descending stair smoothly.Overcome prior art for increasing platform area and increase hull weight that two kinds of solutions adopting cause or cause the drawbacks such as construction trouble.
