Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manual up and down rotary type footbridge lift device,

More particularly, the present invention relates to a manual pedestrian lifting device, and more particularly, to a pedestrian lifting device for manually lifting a pedestrian bridge and manually rotating the pedestrian bridge before a natural disaster, And which can be safely managed and reinstalled.

In general, Taoism is installed in ports and docks, and acts as a bridge to move people or vehicles to floating structures such as ships or floats.

One side of the footbridge is connected to a quay or the like by a hinge or the like, and the free end of the other side is supported on the floating structure to connect the floating structure to the floating structure.

One example of such a technique is disclosed in Document 1 below.

In the following Patent Document 1, as a temporary example, there is shown an example in which, as a temporary example, a pendulum floating on the sea, a body which can be fixed on the land and is hollow inside, a shaft And a connection bar vertically connected to the other side of the shaft, a hinge part connected to the connection bar and capable of pivoting about the connection bar, a hinge part having one side connected to the hinge part, Wherein the hinge portion is rotatable in the up-and-down direction and is rotatable in the left-right direction by the shaft, and the other side of the footbridge is rotated according to the rotation position of the footbridge Wherein a landing bridge is connected to the pier or is capable of being placed on the land,

Another embodiment of the present invention is a method of connecting a pier located at the sea to a land, comprising: a body which can be fixed on land and has an interior space; a body having an inner side rotatably inserted therein and the other side exposed to the outside of the body A hinge part connected to the connection bar and rotatable around the connection bar, and a hinge part having one side connected to the hinge part and the other side connected to the hinge part, A footbridge capable of being connected to the pier. Particularly, the pedestrian apparatus further includes a lifting section which is located on the land and is connected to the other side of the pedestrian bridge to raise or lower the other side of the pedestrian bridge.

However, since the lifting portion of the conventional pedestrian apparatus as described above is constructed such that only the pedestrian is rotated according to the movement of the floating structure, there is no departure and escape function of the pedestrian, and the floating structure and pedestrian are severely damaged .
