DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is to be installed on the roof of a building or the like, and when a helicopter or other aircraft takes off or land, there is no obstacle on the restriction surface, and a person moves while maintaining a substantially horizontal position. It relates to possible elevator and takeoff and landing zone structures.

[0002]

2. Description of the Related Art FIG. 12 is a perspective view showing an example of a conventional heliport. Usually, on the roof of a building such as a building, there are fixed structures such as elevators and stairs so that the roof can be taken out from the top floor. On the other hand, when the heliport is installed on the roof of a building, Article 2 of the Civil Aeronautics Act and its enforcement regulations No. 3
Article 2 requires that there be no obstacles in a predetermined peripheral area of the helipad when the helicopter takes off and land. For this reason, as shown in the figure, the rooftop heliport 500 of the building B supports the floor 501 with the plurality of pillars 502 to construct a landing zone without obstacles around, and includes an approach surface, a transition surface, and a horizontal surface. Try to ensure a restricted surface. A part of this floor 501 has a staircase 503.
The stairs 503 are used so that a pilot or other staff S can go up and down.

[0003]

[Problems to be Solved by the Invention] Recently, the Ministry of Health and Welfare has submitted to the prefectural governor "Disaster enhancement of the initial emergency medical system in the event of a disaster" as a countermeasure against disasters such as earthquakes. As a condition for receiving the designation, it is required that “having a function of transporting a victim, a medical material, or the like by a helicopter by a piston” is required. For this reason, it is inevitable that a heliport needs to be installed on the roof of a hospital building. In such a case, it is necessary to satisfy the requirements stipulated in the above aviation law in taking off and landing of a helicopter. When used in a hospital, it is ideal that the patient be moved while maintaining a substantially horizontal position while being placed on a stretcher, and transported to an intensive care unit (ICU).

[0004] However, the conventional heliport 50 described above.
In the case of 0, since the staff S has to go up and down using the stairs 503, there is a problem that it takes time to transport the patient. On the other hand, although a method of using an elevator to transport the patient is conceivable (not shown), the elevator house protrudes into the landing zone serving as the restriction surface, and becomes an obstacle. In addition, it is generally difficult in Japan to install the elevator away from the H mark in order to satisfy the requirements stipulated by the Civil Aeronautical Law, in Japan where the area of the building rooftop is small. An object of the present invention is to solve such a problem.

[0005]

In order to achieve the above-mentioned object, an elevator according to claim 1 comprises a car for transporting a person or an object, and a car which moves up and down by itself and moves up and down the car inside. A frame, an outer frame which is a main support structure of the elevator and holds the moving frame so as to be able to move up and down, a moving frame elevating means for moving the moving frame up and down by a hydraulic cylinder, a hoist and other actuators, and raising and lowering the basket And a basket elevating means.

When the elevator is mounted on a heliport, for example, the moving frame itself moves up and down, so that the moving frame can be protruded onto the floor of the heliport when the elevator is used. Then, since the car moves up and down in the projecting moving frame, the car can be raised to the floor surface. On the other hand, if the moving frame protrudes above the floor surface, it becomes an obstacle, so the moving frame is lowered together with the basket. Thereby, the floor surface can be made flat. That is, this elevator protrudes its structural part onto the floor surface of the heliport only when the elevator is used, and fits under the floor so as not to hinder the takeoff and landing of the helicopter when not in use, thereby making the floor surface flat. As a result, obstacles during helicopter takeoff and landing can be eliminated, so that an elevator can be installed even when the rooftop area of the building is small, and it is possible to move up and down by the elevator, so that it is almost horizontal. To transport people and goods.

According to a second aspect of the present invention, in the elevator, the moving frame and the car are connected by a pulley device. As described above, by connecting the moving frame and the basket by the pulley device, the car moves up and down as the moving frame moves up and down. The pulley device obtains mechanical gain by a combination of a wire rope and a pulley, and the amount of elevation of the car is determined by the combination of the pulley devices. According to such a configuration, the moving frame and the basket can be moved up and down by one actuator. Further, depending on the combination of the pulley devices, it is possible to freely set the elevator speed of the car.

According to a third aspect of the present invention, there is provided an elevator for transporting a person or an object, a movable frame for holding the cage up and down while being guided by a guide portion provided inside, and supporting the movable frame with a piston. Then, a hydraulic cylinder for raising and lowering the moving frame by hydraulic pressure, an outer frame which is a main support structure of the elevator and holds the moving frame so as to be able to move up and down while being guided by a guide portion, and a car which moves up and down in accordance with the raising and lowering of the moving frame. And a pulley device connecting the both.

When the moving frame is moved up and down by driving the piston of the hydraulic cylinder, the moving frame and the basket connected via the pulley device move up and down in conjunction with each other. That is, since the moving frame and the basket are simultaneously moved up and down by the operation of the hydraulic cylinder, the number of actuators can be reduced,
To that extent, the elevator can be manufactured at low cost. Also, for example, when an elevator is attached to a heliport,
The moving frame protrudes above the floor when using the elevator,
The moving frame moves up and down while being guided by the guide section of the outer frame, and furthermore, the internal basket also moves up and down while being guided by the guide section in the moving frame, so it has sufficient rigidity against gusts etc. Can be demonstrated.

According to a fourth aspect of the present invention, there is provided an elevator for transporting a person or an object, a moving frame for holding the car up and down while being guided by a guide portion provided inside, and supporting the moving frame with a piston. A hydraulic cylinder that raises and lowers the moving frame by hydraulic pressure, a hoisting machine that is provided above the moving frame and winds up the basket with a wire rope, and a main support structure of an elevator that raises and lowers the moving frame while being guided by a guide unit. And an outer frame to be held as possible.

The moving frame is moved up and down by a hydraulic cylinder, and the car is moved up and down by a hoist provided above the moving frame. For this reason, the moving frame and the car can be independently lifted and lowered, so that the acceleration of the car and the like can be adjusted according to the purpose. Further, since the moving frame and the basket move up and down while being guided by the guide portions, it is possible to secure sufficient rigidity against gusts and the like.

According to a fifth aspect of the present invention, there is provided an elevator for transporting a person or an object, and an opening through which the cage protrudes.
And a floor provided at the edge of the floor opening.
A lid provided with an edge shape corresponding to the
A support portion provided on the side surface of the chin,
And is supported by the support portion to support the lid.
And the bar, and a pulley device constructed from wire rope linked to at least the pulley and the hoisting machine is provided in the lower part of the car, have rows lifting the lower support to the cage, and the
When the basket is lifted, the support part hits the lower end of the pillar.
The lid is lifted so that the lid opens as the basket rises .

For example, when the elevator is mounted on a heliport, and the lower portion of the car is supported by a wire rope of a pulley device to drive the hoist, the upper portion of the car projects on the floor surface. Since the car is supported at the lower part, only the upper part of the car protrudes, and other structures do not protrude above the floor surface. Therefore, by lowering the basket, the floor surface can be made substantially flat without obstacles. For this reason, even if the rooftop area of the building is small, it is possible to install the elevator, and since it is possible to move up and down by the elevator,
People and goods can be transported while maintaining a substantially horizontal position. In addition, the cage is loosely restrained by providing a pillar on the lid
To prevent the lid from being blown off by wind, etc.
Can be prevented.

Next, in the aircraft take-off and landing zone structure according to claim 6, the elevator is provided between the upper surface of the building and a heliport surface or another floor surface, and at least the car projects from the floor surface when the elevator is used. In use, the basket is located below the floor surface so that the floor surface is substantially flat.

[0015] The car sticks out of the floor when the elevator is used, so that people can get on and off and carry goods. Further, when the elevator is not used, the car is located below the floor surface and the floor surface becomes substantially flat, so that, for example, there is no obstacle at the time of takeoff and landing of the helicopter. For this reason, it becomes possible to install an elevator even in a small area heliport. Furthermore, since the elevator can be moved up and down, it is possible to carry a person or an article while maintaining a substantially horizontal position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings. The present invention is not limited by the embodiment.

(First Embodiment) FIG. 1 is a configuration diagram showing a heliport elevator according to a first embodiment of the present invention. FIG. 2 is a top view of the elevator shown in FIG. This elevator 100 is a heliport 100
Cylinder base 1 provided between the floor 101 and the building top surface 102 and installed on the building top surface 102
A hydraulic cylinder 2 provided on the cylinder base 1, a moving frame 3 raised and lowered by the hydraulic cylinder 2,
It comprises a cage 4 that moves up and down in the moving frame 3 and an outer frame 5 that is a structure of the elevator 100. The upper part of the piston 21 of the hydraulic cylinder 2 is attached to a support 31 provided on the side surface of the moving frame 3. In the outer frame 5, four square pipes are erected as moving frame elevating guides 51. A pair of guide rollers 32 is provided on the outer periphery of the moving frame 3 in two orthogonal directions. Moving frame 3
Is vertically guided by the moving frame elevating guide 51 via the guide roller 32.

On the other hand, the car 4 constitutes a rope type elevator in the moving frame 3. A plurality of guide rollers 41 are provided around the basket 4. Each guide roller 41 is a set in two orthogonal directions, and the car 4 is guided by four car elevating guides 33 provided in the moving frame 3 via the guide roller 41. Also, the bottom of the cage 4, the upper part of the moving frame 3, the support 3
Rope wheels 61 to 67 are provided on the upper portion of the cylinder base 1 and the upper portion of the cylinder base 1. One end of the wire rope 7 is fixed to the lower part of one support 31, and the other end is a rope wheel 61 (fixed pulley) on the cylinder base 1, a rope wheel 62 above the support 31, and an upper part of the moving frame 3. Rope wheel 63, rope wheel 64 on the bottom of car 4, moving frame 3
Are fixed to the other support 31 via a rope wheel 65 on the opposite side, a rope wheel 66 on the support 31 (both moving sheaves), and a rope wheel 67 on the cylinder base 1.

In the pulley device including the wire rope 7 and the rope pulleys 61 to 67 as shown in FIG. 1, the moving amount of the cage 4 with respect to the moving frame 3 is doubled, so that the moving frame 3 moves by "1". Thereby, the basket 4 moves "3". The rated speed of the basket 4 is, for example, 35 to 45 m / min.
Set within the range. Inside the outer frame 5, there is an elevator 10
A hydraulic power unit 81 and a control device 82 are disposed. A buffer 9 is provided below the basket 4 to reduce the impact when the basket falls. The projecting portion of the car 4 is closed by a lid when the elevator 100 is lowered, and is slid open when the elevator 100 is lifted (not shown). Further, the cage 4 has doorways provided on both sides in one direction, and includes a door machine (not shown). Although the figure shows two persons, the number of persons is not limited to this and can be changed as appropriate according to the use and the scale. In addition, other loading weights, a method in a cage, and the like can be appropriately selected as needed.

The moving frame elevating guide 51 and the basket elevating guide 33 use square pipes, but are not limited thereto. For example, a steel material having a U-shaped or H-shaped cross section can be used. . For example, as shown in FIG. 3, a steel material having an H-shaped cross section may be used for the basket elevating guide 34, and the rollers 43 of the guide rollers 42 may be inserted into the recesses 35 in different directions.
In this case, since the guide roller 42 runs in the recess 35 of the steel material, the cage 4 can be more reliably guided.

Next, the operation of the elevator 100 will be described. FIG. 4 is an explanatory view showing the state of takeoff and landing of the helicopter and the operation of the elevator. FIG. 5 and FIG. 6 are explanatory diagrams showing the elevating operation of the elevator. As shown in FIG. 4A, when the helicopter H lands on the heliport 1000 provided on the roof of the hospital B,
The opening through which the cage 4 protrudes is closed by the lid 103, and the landing zone is flush. Helicopter H
After landing, the lid 103 on the floor 101 is opened and the elevator 100 becomes usable, as shown in FIG. Specifically, when the staff S of the hospital B presses the up button, the door of the elevator 100 is automatically opened and the lid 103 on the floor 101 is automatically opened.
In this state, the basket 4 of the elevator 100 is located on the rooftop as shown in FIG. 5, and the staff S of the hospital B can get on and load luggage and the like.

Next, the staff S gets into the basket 4 and
The basket is raised (FIG. 6 shows the lifting process). First, when the moving frame 3 is raised by the hydraulic cylinder 2, the cage 4 is raised by an amount of three times the moving frame 3 by the action of the pulley device. When the moving frame 3 is raised, its upper part gradually protrudes from the floor 101 and plays a role of supporting the car 4. Next, as shown in FIG. 4C and FIG. 1, when the floor surface of the car 4 rises to the floor position, the car 4 is stopped and the door is opened.
Subsequently, the patient K placed on the stretcher T is placed on the elevator 100 as it is. Then, as shown in FIG. 4D, the patient K is lowered to the rooftop by the elevator 100, while the lid 103 on the floor 101 is closed to eliminate obstacles. This allows the helicopter H to take off.

As described above, when the helicopter H takes off and land, the elevator 100 of the heliport 1000
The structure does not protrude from above 01. Therefore, obstacles in the restricted surface can be eliminated during helicopter takeoff and landing, so that the requirements of the Aviation Law can be satisfied even with a limited rooftop area. Further, the patient K can be transported while maintaining substantially horizontal. Also, since the moving frame 3 and the basket 4 can be moved up and down only by the hydraulic cylinder 2, the number of actuators can be reduced, and the control device can be simplified, so that the elevator can be manufactured at low cost. Further, since the basket 4 moves up and down in the moving frame 3, it can exhibit sufficient rigidity against gusts and earthquakes. In FIG. 1, the moving frame 3 is moved by the hydraulic cylinder 2.
Is raised and lowered, but a hoist may be used instead of the hydraulic cylinder 2.
