Abstract
The utility model discloses a gangway ladder connecting protection device. The gangway ladder connecting protection device comprises an access ladder connecting part rotationally connected with a movable gangway ladder through a first connecting part, and a protection cover plate is arranged above the first connecting part. According to the gangway ladder connecting protection device, the safety degree is improved by rotationally arranging the protection cover plate above a gap between the access ladder connecting part and the movable gangway ladder in a covering mode, a pedestrian can be prevented from accidentally stepping into the gap and being in danger when passing by the gap, meanwhile, the movable gangway ladder can be prevented from pinching the pedestrian when rotating, and the safety level is improved.
Description
Technical field
The utility model relates to shipbuilding field, relate in particular to a kind of for shipbuilding and repair time gangway ladder connection protecting device.
Background technology
Current in shipbuilding and repairing field, all adopt gangway ladder to connect harbour and hull, on handled easily person, go ashore.Gangway ladder is not a part for hull, is the equipment configuring in addition, while needs, need to be connected with hull.
Conventionally, the meeting mistake that the connection location place of adopting gangway ladder hull is difficult to avoid is in certain space, and boats and ships are large-scale weight equipment, in order to improve degree of safety, the attaching parts of all connection locations all must adopt material large-scale and that have larger hardness, therefore, the space of its connection location is generally all larger.
And the space of gangway ladder and hull junction is too large, easily make pedestrian unintentionally pin be fallen into its space, meanwhile, in the process rotating at gangway ladder, constant volume easily clips to pedestrian, so there is very large potential safety hazard, need to take necessary safety method.
Summary of the invention
It is a kind of simple in structure that the purpose of this utility model is to provide, for the gangway ladder connection protecting device of ramp and harbour ascending stair junction.
To achieve these goals, the gangway ladder connection protecting device for ramp and harbour ascending stair junction that the utility model provides comprises: ascending stair connecting portion, ascending stair connecting portion is rotationally connected by the first connecting portion and ramp, and the first connecting portion top is provided with protective cover plate.Thus, by protective cover plate is set, the first connecting portion place is covered, making the first connecting portion place is a plane, prevents that pedestrian from walking out-of-date, unintentionally pin is snapped in to the first connecting portion, causes danger.
In some embodiments, the first connecting portion is that first of pair of opposing connects jack, the both sides, one end that ramp is connected with harbour ascending stair are respectively equipped with one second and connect jack, first connects jack is connected jack coincidence with second, connect jack and second by an adapter shaft through first and connect jack, and adopt bearing pin to lock and connect.Thus, ramp such as is connected in around the shaft rotationally at the terraced connecting portion.
In some embodiments, protective cover plate is connected with the rotating shaft of ascending stair connecting portion upper surface, and protective cover plate is covered on the first connection jack and second and connects top, jack junction.Thus, in the time of Assembly &Disassembly, only need raise protective cover plate, while normally use, cover protective cover plate, convenience, practicality and safety.
Accompanying drawing explanation
Fig. 1 is the structural representation of the gangway ladder connection protecting device of a kind of embodiment of the utility model;
Fig. 2 is the part-structure schematic diagram of ascending stair connecting portion in the gangway ladder connection protecting device shown in Fig. 1;
Fig. 3 is the part-structure schematic diagram of ramp in the gangway ladder connection protecting device shown in Fig. 1.
The specific embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail to explanation.
Fig. 1 has schematically shown the gangway ladder connection protecting device according to a kind of embodiment of the utility model.
As shown in Figure 1, gangway ladder connection protecting device, comprising: ascending stair connecting portion 21, ascending stair connecting portion 21 is rotationally connected by the first connecting portion and ramp 2.
As shown in Figure 2, the first connecting portion is pair of opposing first connects jack 210, and each first connects jack 210 is two and is oppositely arranged and pertusate contiguous block is established at center.The first connecting portion is located at the side side that ascending stair connecting portion 21 is relative with ramp 2.
As shown in figures 1 and 3, the both sides, one end that ramp 2 is connected with harbour ascending stair are respectively equipped with one second and connect jack 200, each second connects jack 200 Wei Yikuai centers establishes pertusate contiguous block, and the internal diameter size that the second internal diameter size and first that connects jack 200 center holes connects jack 210 center holes is identical.
As shown in Figure 1, second connects jack 200 is arranged between the first connection jack 210, make the center hole of the second connection jack 200 be connected jack 210 center holes coincidences with first, and be arranged in the first connection jack 210 and the second connection jack 200 center holes by an adapter shaft 11, then adopt bearing pin 12 to lock and connect.The utility model adopts said method to connect ramp 2 and ascending stair connecting portion 21, without welding, and convenient installation and dismounting.
As depicted in figs. 1 and 2, the side that ascending stair connecting portion 21 is relative with ramp 2, crest line place, top connects a protective cover plate 211, and protective cover plate 211 is connected in ascending stair connecting portion 21 by rotating shaft.As shown in the figure, protective cover plate 211 is an oblong steel plate, the width sizableness of its length scale and ramp 2, and width is the space enough covering between ascending stair connecting portion 21 and ramp 2.It is parallel with the long limit of protective cover plate 211 that the both sides, a wherein long limit of protective cover plate 211 connect respectively rotating shaft 23, two rotating shafts 23; The crest line both sides of ascending stair connecting portion 21 are respectively equipped with a beam barrel 22, and the rotating shaft 23 of protective cover plate 211 is inserted in beam barrel 22, and protective cover plate 211 can be rotated along rotating shaft.
Gangway ladder connection protecting device of the present utility model, by ascending stair connecting portion and ramp above gap, lid is established a protective cover plate rotationally, improve degree of safety, pin is fallen into gap causes danger unintentionally through out-of-date to prevent pedestrian, also avoided ramp to crush pedestrian in the process of rotating, improved safe class simultaneously.Meanwhile, gangway ladder connection protecting device of the present utility model is simple in structure, is suitable for practicality.
