Description

A kind of sea situation that adapts to jolt log in ladder

Technical field

The utility model belongs to the technical field of marine deck machinery, and what be specifically related to a kind of sea situation that adapts to jolt logs in ladder.

Background technology

For large ship especially pleasure boat, after reaching harbour, passenger all adopts the landing approach logging in staircase, height due to relative ground, deck constantly changes along with the change of wave, traditional ladder that logs in is fixed with the design angle on ground, when altitude above deck changes, there is certain angle between pedal and deck, passenger is had a negative impact through the safety of staircase traveling comfort.

As can be seen here, the landing approach of current boats and ships does not better solve occupant comfort and safety problem, lacks one and can meet passenger comfort requirement, can meet again safety, reliability requirements log in ladder.

Utility model content

In view of this, what the utility model provided a kind of sea situation that adapts to jolt logs in ladder, can solve the problem that crewman steadily logs in when boats and ships fluctuate, can meet safety, traveling comfort, reliability requirements again simultaneously.

Realize the technical solution of the utility model as follows:

What adapt to jolt sea situation logs in a ladder, comprises four terraced beams, two arm-rest frames, multiple pedal and four pulleys; External equipment is the deck of boats and ships;

Described pedal is square plate, and a pair relative side of each pedal is flexibly connected with terraced beam, and the point of connection of same side is two, and each point of connection correspondence connects a terraced beam, and the point of connection of both sides is symmetrical;

The deck of one end and the boats and ships of ladder beam is hinged, and the other end is connected with a pulley respectively, and on two terraced beams above two arm-rest frames are connected in respectively, two arm-rest frames are parallel to each other, and arm-rest frame place plane orthogonal is in place, deck plane.

Further, terraced beam is flexibly connected by active pin shaft with between pedal.

Beneficial effect:

1. what the utility model provided adapt to jolt sea situation log in ladder, being rigidly connected of ship deck and stair is become hinges and be connected, terraced beam is become active pin shaft with the rigid attachment between pedal connect, ensure that pedal plane is parallel with deck all the time, improve traveling comfort and safety that boats and ships log in ladder.

2. the utility model compact conformation, easy installation and removal, improves the convenience of workman's construction, maintenance.

Accompanying drawing explanation

Fig. 1 of the present utility modelly logs in terraced structural representation.

Wherein, 1-deck, 2-hinges, 3-arm-rest frame, 4-ladder beam, 5-pedal, 6-pulley.

Detailed description of the invention

To develop simultaneously embodiment below in conjunction with accompanying drawing, the utility model is described in detail.

As shown in Figure 1, what the utility model provided a kind of sea situation that adapts to jolt logs in ladder, comprises four terraced beams, 4, two arm-rest frames 3, multiple pedal 5 and four pulleys 6;

Described pedal 5 is square plate, and a pair relative side of each pedal 5 is flexibly connected by active pin shaft with terraced beam 4, and the point of connection of same side is two, and each point of connection correspondence connects a terraced beam 4, and the point of connection of both sides is symmetrical;

It is hinged that hinges 2 is passed through on the rectangular distribution in one end of four terraced beams 4 and the deck 1 of boats and ships, and the other end is connected with a pulley 6 respectively, ensures that pulley 6 can slide on road surface; Two arm-rest frames 3 are welded on two terraced beams 4 of top respectively, and two arm-rest frames 3 are parallel to each other, and arm-rest frame 3 place plane orthogonal is in place, deck 1 plane.

Log in ladder work when doing, fluctuate along with wave in deck 1, the height on relative ground is also in continuous change.The up-and-down movement on deck 1 drives terraced beam 4 to move, thus makes pulley 6 at taxiing, and the mutual activity of terraced beam 4 drives the activity of pedal 5.In whole process, form parallelogram between deck 1, terraced beam 4 and pedal 5 three, the principle using parallelogram opposite side parallel is known: pedal 5 is parallel with deck 1 all the time.So just effectively improve safety and the traveling comfort of passenger.

In sum, these are only preferred embodiment of the present utility model, be not intended to limit protection domain of the present utility model.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.

Claims (2)

1. what can adapt to jolt sea situation logs in a ladder, it is characterized in that, comprises four terraced beams, two arm-rest frames, multiple pedal and four pulleys; External equipment is the deck of boats and ships;

Described pedal is square plate, and a pair relative side of each pedal is flexibly connected with terraced beam, and the point of connection of same side is two, and each point of connection correspondence connects a terraced beam, and the point of connection of both sides is symmetrical;

The deck of one end and the boats and ships of ladder beam is hinged, and the other end is connected with a pulley respectively, and on two terraced beams above two arm-rest frames are connected in respectively, two arm-rest frames are parallel to each other, and arm-rest frame place plane orthogonal is in place, deck plane.

2. as claimed in claim 1 a kind of sea situation that adapts to jolt log in ladder, it is characterized in that, terraced beam is flexibly connected by active pin shaft with between pedal.
