Description

Elevator for ship

Technical Field

The present invention relates to a ship elevator for transporting passengers such as passengers and crews to halls on respective floors in ships such as tankers, cargo ships, and passenger ships.

Background

A ship on which passengers such as passengers and crew members are mounted is provided with a ship elevator for transporting the passengers to halls on each floor. Therefore, passengers in the ship can move to each floor by selecting any destination floor button provided in the car of the elevator in addition to the steps. Since the ship elevator operates in a ship traveling on water, it is designed to be able to withstand shaking and impact.

The ship elevator is installed in a hoistway that connects the respective floors. Components required for the operation of the ship elevator, such as a car and a counterweight, are disposed in the four side walls of the elevator shaft in a dispersed manner. The components are provided by welding to the side walls. For example, a plurality of brackets are welded and fixed to a side wall of the elevator shaft, and a car, a counterweight, and the like are attached to the brackets.

However, when the welding is performed in the ascending/descending path, the wall surface in the welded ascending/descending path becomes a high-temperature state, and even the wall surface on the back side which receives heat conduction from the wall surface becomes a high-temperature state. Thus, there are problems as follows: the coating on the wall surface subjected to heat conduction melts and needs to be recoated. The coating in the ship is a special coating, and several times of coating is performed, and even in such a coating, it is necessary to satisfy a certain standard specific to the ship elevator. Therefore, in installation and construction of the ship elevator, it is necessary to perform the recoating of the special coating concerning the wall surface in the elevator shaft, that is, the amount of the four side surfaces, and thus a lot of time is required. As a technique for solving such a problem, patent document 1 is cited.

In the marine elevator of patent document 1, a pair of guide rails is fixed to one of four wall surfaces in the elevator shaft. The pair of guide rails hold the car and the counterweight in the elevator shaft and guide the car and the counterweight to move up and down in the elevator shaft. A cantilever protruding toward the wall surface is fixed to the car, and a roller provided at a tip end of the cantilever is assembled to the guide rail. Further, a travel path of a counterweight connected to the car via a chain is provided between the pair of guide rails. In this way, in the marine elevator, the car and the counterweight are supported by the pair of guide rails provided on one side surface in the elevator shaft. Therefore, the marine elevator of patent document 1 can shorten the time taken to install the marine elevator by collecting the components necessary for the operation of the marine elevator, such as the car, the counterweight, and the guide rail, on one wall surface in the elevator shaft and recoating only one wall surface during installation and construction of the marine elevator in the elevator shaft.

Problems to be solved by the invention

However, in a ship sailing on water, a space for installing an elevator in the ship needs to be provided, and the space available for the elevator is limited, so that it is necessary to reduce the cross-sectional area of the elevating path as much as possible. On the other hand, in a ship elevator, unlike an elevator on land, it is obligated to design as follows: the car is provided with an escape door for allowing passengers in the car to escape from the interior of the hoistway, and the hoistway is provided with an escape area for allowing passengers who have escaped from the car to move from the hoistway to each floor by their own force. Therefore, in the marine elevator, although it is necessary to reduce the cross-sectional area of the elevating path as much as possible, it is necessary to provide an escape area in the elevating path in which passengers who have escaped from the car can move to the floor of each floor.

Further, when each component necessary for the operation of the elevator is installed in the escape area, there is a risk that the occupant who has escaped from the car comes into contact with the component. Therefore, there is a problem that the cross-sectional area of the ascending/descending path must be increased to avoid such contact. Thus, the marine elevator has the following problems: it is necessary to reduce the cross-sectional area of the elevator shaft as much as possible, and it is difficult to reduce the cross-sectional area of the elevator shaft from the positional relationship between the arrangement region and the escape region of the components required for the operation of the ship elevator.

Means for solving the problems

The present invention has been made in view of the above problems, and an object of the present invention is to provide a ship elevator in which an arrangement region and an escape region of each component required for operation of the ship elevator are divided into different regions in an elevator shaft, and a cross-sectional area of the elevator shaft is reduced, thereby efficiently utilizing a space in a ship.

That is, the present invention relates to a ship elevator for transporting passengers to each floor in a ship, the ship elevator comprising: an elevation path which connects the layers and is provided with an ascending and descending port of each layer on the front wall surface; and a car having a car door provided to face the entrance and the exit, and having an escape door on a ceiling for ascending and descending in the hoistway to transport passengers to each floor, wherein one of hoistway side surfaces adjacent to a front wall surface of the hoistway is provided as a converging side surface on which components necessary for operation of the car are arranged in a concentrated manner, and the car is provided with: a pair of support members fixed to the collecting side surface at a predetermined interval in a horizontal direction; a guide rail fixed to the pair of support members and provided along a vertical direction in the ascending/descending path; a guide member that travels along the guide rail and holds the car in a cantilever state; a counterweight that is connected to the car via a plurality of ropes wound around a sheave, and that moves vertically in a travel path provided between the pair of support members as the car moves up and down; a landing door introduction area provided between the front wall surface and one of the support members, for accommodating the car door; and a cable moving region provided between the other support member and a rear wall surface of the elevator shaft, in which a cable for supplying power to the car moves as the car moves up and down, wherein an escape region in which an elevator shaft can be disposed is provided between the rear wall surface of the elevator shaft and the car, and between a side surface of the elevator shaft facing the converging side surface and the car, and passengers who escape from the car through the escape door use the elevator shaft when moving to each floor.

Effects of the invention

According to the marine elevator of the present invention, the components necessary for the operation of the elevator, such as the car and the counterweight, the landing door entrance region, and the cable movement region are disposed in a concentrated manner between the car and the converging side surface, and the escape region is disposed between the rear wall surface and the car, and between the side surface opposite to the converging side surface and the car. Thus, the ship elevator can divide the arrangement region and the escape region of each component into different regions in the lifting path, and can reduce the cross-sectional area of the lifting path.

In the marine elevator according to the present invention, since the respective components such as the car and the counterweight are provided on the support member fixed to the converging side surface, only one surface of the converging side surface may be subjected to welding work when the marine elevator is installed. Therefore, in the installation construction of the ship elevator, the recoating caused by welding can be omitted to the extent of performing the recoating of only one side surface, and thus the time required for the work can be greatly shortened.

Further, since the landing door introducing region is provided between the front wall surface in the elevator shaft and one of the support members, the landing door of the car can be opened greatly. Therefore, the landing door can be opened greatly while the cross-sectional area of the lifting path is reduced, and even an article having a large lateral width can be transported by the marine elevator.

Detailed Description

Hereinafter, a ship elevator according to the present invention will be described in detail with reference to the accompanying drawings.

Fig. 1 is a plan view showing a cross section of an elevating path of an embodiment of an elevator for a ship to which the present invention is applied. Fig. 2 is a cross-sectional view showing an outline of the marine elevator when the car door is viewed from the inside of the car. The ship elevator 1 is used when passengers are transported to each floor in a ship such as an oil tanker, a cargo ship, or a passenger ship.

As shown in fig. 1, the ship elevator 1 is provided with a car 50 in an elevator shaft 10. The car 50 ascends and descends in the hoistway 10. The elevator shaft 10 has a substantially rectangular cross-section and is surrounded by wall surfaces in all four directions. The lifting path 10 is communicated from the lowermost layer to the uppermost layer of the floors of each floor. As shown in fig. 2, a sheave 80 connected to a motor is provided at the uppermost part of the elevator shaft 10. The car 50 is suspended and supported by being connected to one end of 6 ropes 8 wound around the sheave 80. On the other hand, a counterweight 40 is connected to the other end of the rope 8. That is, the car 50 is connected to the counterweight 40 via the rope 8.

The car 50 is wound around a sheave 80 provided at the uppermost portion of the elevator shaft 10 and lifted and lowered in the elevator shaft 10. When the car 50 ascends and descends, the counterweight 40 ascends and descends in the opposite direction to the car 50 along with this. That is, when the car 50 ascends, the counterweight 40 descends, and when the car 50 descends, the counterweight 40 ascends. A spring 15 is provided at the lowermost edge of the elevating path 10. The spring 15 can reduce the impact when the car 50 and the counterweight 40 fall due to some cause in an emergency of the ship.

A landing entrance 100 is opened in a front wall surface 11 of the lifting path 10. The entrance 100 communicates the floors of each floor with the lifting path 10, and is provided for each floor. A floor door 110 is provided at the entrance 100. When the floor door 110 and the car door 52 are opened, the passenger can get on the car 50.

The passenger gets into the car 50 from the car door 52, and presses any destination button by an operation panel 53 in the car 50 to operate the marine elevator 1. When the destination floor button is pressed, a control panel controls a motor and the like provided on the sheave, and the car 50 is raised and lowered to any floor. When arriving at any floor, the car doors 52 in the car 50 open and can move to the floor of the floor. Thus, the ship elevator 1 can transport passengers to each floor.

As shown in fig. 1, a converging side surface 12 is provided on one side surface of the elevator shaft adjacent to the front wall surface 11 of the elevator shaft 10, and each component necessary for the operation of the car 50 is arranged so as to converge on the converging side surface 12. A plurality of mounting portions 24 are welded and fixed to the collecting side surface 12, and the plurality of mounting portions 24 are provided at a predetermined interval in the vertical direction of the ascending/descending path 10. The mounting portion 24 has an elongated shape extending in the width direction of the collecting side surface 12.

Each mounting portion 24 is provided with a pair of support members 20. The pair of support members 20 includes a support member 20a provided on the front wall surface 11 side and a support member 20b provided on the rear wall surface 14 side facing the front wall surface 11. The support member 20a is provided at a predetermined interval from the support member 20 b. The support member 20 protrudes toward the center of the hoistway 10.

A partition plate 30 is provided at the center of the support member 20. As shown by the broken lines in fig. 3, the partition plate 30 divides a second traveling path 5, in which a guide member 25 provided in the car 50 described later travels, and a first traveling path 4, in which the counterweight 40 travels. The first travel path 4 is provided between the partition plate 30 and the collecting side surface 12. On the other hand, the second travel path 5 is provided between the partition plate 30 and the car 50.

A pair of first guide rails 22 are provided on the first travel path 4. The first guide rail 22 forms a long rail along the vertical direction of the ascending/descending road 10. The length of the first guide rail 22 is substantially the same as the entire length of the elevator shaft 10. As shown in fig. 3, the first rail 22 is fixed to the support member 20 by bolts. The first guide rail 22 is formed in a substantially T-shaped cross section.

A counterweight 40 as a counter weight is disposed on the first travel path 4. The counterweight 40 is a member that efficiently drives the sheave 80 with a small amount of energy when moving the car 50 up and down. The counterweight 40 is assembled to the pair of first guide rails 22. Thereby, the counterweight 40 can be guided by the first guide rail 22 and travel along the vertical direction of the ascending/descending path 10 in the first travel path 4. The weight of the counterweight 40 is designed to be the sum of half the rated load of the marine elevator 1 and the cage 50.

A pair of second guide rails 21 are provided on the second travel path 5. The second guide rail 21 forms a long rail along the vertical direction of the ascending/descending road 10. The length of the second guide rail 21 is substantially the same as the entire length of the ascending/descending path 10. As shown in fig. 3, the second rail 21 is fixed to the support member 20 by a bolt. The second guide rail 21 is formed in a substantially T-shaped cross section.

A guide member 25 that moves up and down in the second travel path 5 is disposed between the pair of second guide rails 21. A pair of sliders 23 is provided on the guide member 25. The slider 23 is assembled to the second guide rail 21. Thereby, the guide member 25 can be guided by the second guide rail 21 to be raised and lowered in the vertical direction of the ascending and descending path 10 in the second travel path 5.

A car 50 disposed near the center of the elevator shaft 10 is attached to the guide member 25. The car 50 is supported by being connected to the counterweight 40 via the rope 8 wound around the sheave 80. Therefore, the car 50 is held in a cantilever state via a pair of support members 20 fixed to the converging side surface 12. In addition, since the car 50 is assembled to the second guide rail 21 by the slider 23 of the guide member 25, the movement of the car 50 in the horizontal direction can be suppressed, and the car 50 can be smoothly raised and lowered without shaking.

The car 50 has a car door 52 on the front wall surface 11 side of the elevator shaft 10. When the car door 52 is opened, the car door 52 is accommodated in a landing door introduction area 120, and the landing door introduction area 120 is provided between the front wall surface 11 and the support member 20a provided on the front wall surface 11 side of the pair of support members 20. This allows the landing door 52 to be opened largely.

As shown in fig. 2, an operation panel 53 is provided in the car 50. The operation panel 53 is operated when an occupant gets into the car 50 and designates an arbitrary destination floor. This allows the passenger to move to a hall of any floor.

An escape ladder 51 is provided at a position facing a car door 52 provided in the car 50. The escape ladder 51 is provided upward in the car 50. When the car 50 needs to escape, for example, in an emergency stop due to an emergency situation, the passenger in the car 50 can climb the escape ladder 51 and escape to the outside of the car 50 through an escape door, not shown, provided on the ceiling of the car 50. The position where the escape door is provided does not necessarily need to be the ceiling of the car 50, and may be changed as appropriate depending on the environment of the elevator or the elevator shaft being constructed.

The car 50 is provided with a cable, not shown, for supplying electric power to the car, a control panel, a motor, and the like. One end of the cable is connected to the car 50 and the other end is connected to a power source. The cable is wound around a pulley 6 as shown in fig. 4. The pulley 6 is always applied with tension by stretching the cable. Thereby, the cable can be prevented from being loosened.

The pulley 6 includes a pulley main body 61 and rolling elements 62 provided above and below the pulley main body 61. The pulley 6 is provided in a cable moving region 60, and the cable moving region 60 is provided between the support member 20b facing the support member 20a and the rear wall surface 14 facing the front wall surface 11. The pulley 6 moves the roller 62 in the elevator shaft 10 in contact with a pulley guide rail 63 provided in the cable moving area 60.

The pulley 6 is constituted by a movable sheave connected to the car 50 via the cable. Therefore, the pulley 6 moves up and down at half the speed of the car 50 as the car 50 moves up and down. That is, the pulley 6 stays at the lowermost floor of the ascending/descending path 10 when the car 50 descends to the lowermost floor, and stays at a height approximately half that of the ascending/descending path 10 when the car 50 ascends to the uppermost floor.

In the ascending/descending path 10, escape regions 70 are formed between the car 50 and the rear wall surface 14, and between the car 50 and a side wall facing the collecting side surface 12 in the ascending/descending path 10. The escape area 70 is a space formed in a substantially L shape along the periphery of the car 50 and continuously formed along the vertical direction of the ascending/descending path 10. The escape area 70 is a space for allowing passengers using the ship elevator 1 to safely escape from the hoistway in an emergency such as a failure occurring during the operation of the ship elevator 1. Since the components necessary for the operation of the elevator, such as the car 50 and the counterweight 40, the landing door access area 120, and the cable movement area 70 are disposed so as to be concentrated on the converging side surface 14, the escape area 70 is a relatively safe area divided into different areas with respect to these components and areas. An elevator 71 is provided on a side surface of the escape area 70 that is opposite to the collecting side surface 12. The elevator 71 extends in the vertical direction of the elevator 10, and guides the passengers escaped from the car 50 to a passage (not shown) for communicating with the floor of each floor. Therefore, the passengers using the ship elevator 1 can escape from the car 50 in the emergency and safely evacuate using the elevator 71 by their own force. In the present embodiment, the ascending/descending path ladder 71 is provided on the side surface facing the collecting side surface 12, but if it is provided in the escape area 70, it does not interfere with the arrangement of the components necessary for the operation of the ship elevator 1, the cable moving area 60, or the landing door entry area 120, and thus it can be changed as appropriate.

According to the ship elevator of the present invention configured as described above, since the components necessary for the operation of the elevator, such as the car 50 and the counterweight 40, the landing door introducing region 120, and the cable moving region 70 are collectively disposed between the car 50 and the converging side surface 12, the components are not disposed between the rear wall surface 14 and the car 50, and between the side surface facing the converging side surface 12 and the car 50, that is, in the escape region 70. Therefore, the ship elevator 1 according to the present invention can divide the arrangement region and the escape region 70 of the respective components into different regions, and can reduce the cross-sectional area of the elevator shaft 10. Further, by dividing the arrangement region and the escape region 70 into different regions, it is possible to ensure the safety of the passenger who escapes from the car 50 toward the floor of each floor by the force of the passenger.

In the marine elevator 1 according to the present invention, the components necessary for the operation of the elevator, such as the car 50 and the counterweight 40, are held in a cantilever state by the support member 20 provided on the collecting side surface 12. Therefore, when the ship elevator 1 is installed, only the collecting side surface 12 of the four wall surfaces of the ascending/descending path 10 may be subjected to welding. Therefore, since the recoating by welding to the wall surface of the ascending/descending path 10 can be omitted to the extent that only one side surface is welded, the time required for installation and construction of the ship elevator 1 can be significantly shortened.

A landing door access area 120 is provided between the front wall surface 11 and the support member 20a in the elevator shaft 10, and the landing door access area 120 accommodates the car door 52 provided to the car 50. Therefore, the marine elevator 1 can reduce the cross-sectional area of the elevator shaft 10 and largely open the car doors 52, and thus can transport even an article having a large lateral width.
