Background
After small and medium-sized bulk cargo ships, passenger and rolling ships and multipurpose ships enter a port, gangways cannot be normally released due to the limitation of wharf environment. In order to realize the loading and unloading of personnel as soon as possible, the temporary pedestrian passageway is generally formed by the dock ladder and a bulwark ladder matched with a ship in the industry. The lap joint point of this passageway uses ship board wallboard assigned position to set up the connection otic placode as the fulcrum, and the otic placode that is located the ship board wallboard outside is used for connecting the pier ladder, and the otic placode that is located ship board wallboard inboard is used for connecting the bulwark ladder, and this kind of lap joint structure who uses ship board wallboard as the fulcrum is simple, connect reliably, can satisfy the requirement that personnel's safety went on and off the ship. However, the structure has three problems in practical use, namely, the workload of butt joint and locking is large; secondly, the lap joint position is fixed, and the lap joint can not be carried out as required; and thirdly, the lug plates preset on the inner side and the outer side of the ship board wall plate are in an outward convex shape, and the outward convex lug plates are barriers at the side of the ship board wall plate in a non-lap joint period as the lug plates exceed the plate surface of the ship board wall plate at the position, so that the normal operation of the area is influenced, and the passing quality of personnel is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model discloses mainly to prior art's not enough, provide a pier ladder and bulwark ladder overlap joint component, this component is prefabricated connecting piece, and connection structure is simple, the overlap joint is convenient, the lock position is reliable, does not establish fixed position's otic placode on the most important ship board wallboard, can accomplish as required the overlap joint accessible pedestrian passageway.
The utility model discloses a technical goal is realized to following technical scheme.
The overlapping component of the wharf ladder and the bulwark ladder comprises a groove-shaped seat, a nut, a screw rod, a side ear plate and an upper ear plate. The improvement is that: the cross section of the groove-shaped seat is a rectangular groove with a gap reserved in the combination part of the bottom edge and the right side edge, the rest bottom edge is used for fixedly connecting a nut with an axis in a vertical arrangement, a screw screwed in from the bottom end of the nut forms a self-contained locking structure, an upper lug plate vertically arranged upwards is fixedly connected to the top surface of the groove-shaped seat by the inner side, and the outer side surface of the groove-shaped seat is fixedly connected with a transverse side lug plate.
As a further improvement scheme, the width B of the groove-shaped seat (1) is 5-10 mm wider than the transverse top edge of the ship board wallboard.
As a further improvement scheme, the upper ear plates are arranged alternately, each connecting point consists of two connecting points, each connecting point consists of four connecting points, and the distance between the connecting points is equal to the distance between the ear plates preset at the top end of the matched wharf ladder.
As a further improvement scheme, the side ear plates are arranged alternately, each connecting point consists of two connecting points, each connecting point comprises four connecting points, and the distance between the connecting points is equal to the distance between the ear plates preset at the top end of the matched bulwark ladder.
Compared with the prior art, the utility model, following positive effect has:
1. the groove-shaped seat is a sheet metal component, and has the advantages of simple structure, easy manufacture, convenient connection and reliable locking;
2. the groove-shaped seat is spanned on the transverse top edge of the ship board wall plate, and the adjustable structure is convenient for the bulwark ladder to be lapped with the wharf ladder at the most proper position;
3. the gangway ladder is lapped with the wharf ladder through the groove-shaped seat, and the hinged connection structure is convenient for quick assembly and disassembly and also convenient for storing all disassembled components in different places, so that no lapping member is remained on the shipboard wallboard in the non-lapping stage, and the original condition is still maintained.

Fig. 2 is a top view of fig. 1.
Fig. 3 is a schematic structural view of a bulwark ladder overlapping a wharf ladder through a slotted seat.
Detailed Description
The invention will be further explained with reference to the drawings and the examples.
The overlapping component of the wharf ladder and the bulwark ladder shown in figure 1 comprises a groove-shaped seat 1, a nut 2, a screw rod 3, a side ear plate 4 and an upper ear plate 5. The groove type seat 1 is a sheet metal component, the cross section of the groove type seat is a rectangular groove with a gap reserved between the bottom edge and the inner side edge joint part, the groove width B is wider than the transverse top edge of the ship board wallboard 8, the width of the embodiment is 5mm, and the gap is formed when the groove type seat 1 displaces along the ship board wallboard 8. The lower corner of the right side of the groove-shaped seat 1 is in a notch shape, and the bottom edge and the right side edge are incomplete. The rest bottom edge is fixedly connected with a nut 2 with an axis in a vertical position, and a screw 3 screwed in from the bottom end of the nut 2 forms a self-contained locking structure. In order to facilitate the external connection of the wharf ladder 6 and the bulwark ladder 7, two groups of upper ear plates 5 are fixedly connected on the top surface of the groove-shaped seat 1 close to the inner side, and two groups of side ear plates 4 are fixedly connected on the outer side surface of the groove-shaped seat 1.
