Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a marine elevator for transporting crew members such as boarding passengers and crew members to halls on each floor in ships such as tankers, cargo ships, and passenger ships.

2. Description of the Related Art Ships carrying crew members such as passengers and crew members are equipped with ship elevators for transporting crew members to halls on each floor. Therefore, crew members in the ship can move to each floor by selecting an arbitrary destination floor button provided in the cage of the elevator in addition to the stairs. Marine elevators are specially designed to withstand shaking and shocks because they operate inside a vessel that travels on water.

A marine elevator is installed in a hoistway that connects each floor. Components necessary for the operation of a marine elevator, such as a cage and a counterweight, are provided dispersedly on four side walls in the hoistway. Installation of each component is done by welding to the side wall. For example, a plurality of brackets are welded to the side wall of the hoistway, and a cage, counterweight, etc. are attached to the brackets.

However, when welding work is performed in the hoistway, heat is conducted from the wall surface of the hoistway that is welded, and the wall on the opposite side of the wall surface becomes highly heated. As a result, there is a problem that the paint on the wall is melted and needs to be repainted. The painting inside the ship is made up of many layers of special paint, and it is necessary to meet certain standards. Therefore, the installation work of the ship elevator takes a lot of time due to the need to repaint the walls in the hoistway, that is, the four side walls. Patent document 1 is mentioned as what solves such a subject.

In the ship elevator of Patent Document 1, a pair of guide rails are fixed to one wall surface among four wall surfaces in the hoistway. A cantilever arm projecting from the wall surface is fixed to the cage, and a roller provided at the tip of the cantilever arm is assembled to the guide rail. A running path for a counterweight is provided between the pair of guide rails. For this reason, in the marine elevator of Patent Document 1, constituent members necessary for the operation of the marine elevator, such as the cage, counterweight, and guide rail, are gathered on one wall surface in the hoistway. Since only 1 repainting occurs, repainting for three walls can be omitted.

However, due to the limited space in ships traveling on water, the hoistway cross-section should be as small as possible. On the other hand, in a ship elevator, it is obligatory to provide an escape door on the ceiling of the car and to provide an escape area for each floor from the hoistway. In addition, if each component that moves up and down the hoistway is installed in the escape area, it is dangerous for passengers to escape from the cage to each floor. preferably As a result of arranging the escape area and each component at a position where they do not interfere with each other, there is a problem that the cross-sectional area of the hoistway increases. Therefore, while there is a need to reduce the cross-sectional area of the hoistway for marine elevators, it is difficult to reduce the cross-sectional area of the hoistway in order to provide the necessary components and an escape area for a marine elevator. There was a problem.

The present invention has been made in view of such problems, and its object is to reduce the cross-sectional area of the hoistway while arranging each component necessary for the operation of a marine elevator at a position that does not interfere with the escape area. To provide a marine elevator capable of efficiently utilizing a space in a ship.

An escape passage area having an escape ladder is provided between the rear wall surface and the car and between the side surface facing the consolidated side surface and the car.

According to the marine elevator of the present invention, the structural members necessary for the operation of the elevator such as the cab and the counterweight, the entrance/exit door draw-in area, and the cable movement area are arranged between the cab and the integrated side surface. , between the rear wall and the cab, and between the converging side and the opposing side and the cab, are located escape areas. Therefore, the marine elevator 1 can reduce the cross-sectional area of the hoistway while preventing interference between the constituent members and the escape area.

In addition, in the marine elevator of the present invention, each component such as the cage and the counterweight is provided on the support member fixed to the aggregated side surface. You should do the construction work. Therefore, in the installation work of the ship elevator, recoating by welding can be omitted for only one side, and the time required for the work can be greatly shortened.

Furthermore, since the passenger door pull-in area is provided between the front wall surface in the hoistway and one of the support members, the passenger door of the car can be opened wide. Therefore, the boarding door can be opened wide while the cross-sectional area of the hoistway is reduced, and even cargo with a large width can be transported by the marine elevator.
