Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a small number of elevators, such as an elevator for a private house or an office, used by a small number of people.

[0002]

2. Description of the Related Art A lifting device provided for use by a small number of people generally has a structure in which a car is wound by a drum type wire winder.

[0003] There is also a lifting device provided as a small number of lifting devices for raising a car by hydraulic pressure.

Although not practically used, there is an example of a screw type lifting device.

[0005]

However, the wire hoisting type lifting device of the first method requires a high steel tower and a counterweight to support the hoisting portion, and is used in a private house on the second or third floor. The structure is too expensive to adopt,
There was a drawback that the price was high. In particular, the wire rope has to be double-tracked to prevent falling, and it is necessary to install a governor, a catcher, a shock absorber, etc., resulting in high costs. Inspection and repair required specialized technical skills and was expensive.

In the second method, since a hydraulic device is used, the cost of the device is high, and specialized technical skill is required for inspection and repair. Also, because of the hydraulic pressure, there were concerns about an unpredictable fall accident such as a rat biting a high-pressure rubber tube. Oil spills could lead to fire due to flammable hydraulic fluid in private homes. If the building specification was made to be fireproof, the cost was high.

The third method is that the cost of the long cutting screw shaft and the rolling screw shaft used for the lifting device is high, and in the method of rotating the screw shaft, since the screw shaft mass is large, the capacity of the drive motor becomes large. In addition, there are problems such as rotational vibration occurring in the screw shaft and sound vibration generated in the drive section entering the cage in the method of rotating the female screw, and no solution was found for both cost and performance. It has not been put to practical use.

All methods except the screw type have a structure in which the car can be rapidly dropped in the event of a device failure or damage, and thorough inspection and maintenance were required to avoid this. In addition, the structure was such that the passengers could not get out of the room by themselves at the time of the breakdown stoppage or the power outage stoppage, so it was necessary to assist others. For this reason, there is a drawback in that emergency evacuation is not possible in the event of a fire or earthquake, which is a safety issue.

Most of the conventional lifting devices are of the type installed at the time of building a new building, and it is difficult to additionally install them in the existing building. This is because the conventional lifting device bears the vertical load on the lifting device side, but the horizontal load is handled on the building side, that is, it is a semi-self-supporting structure, so it is added to the existing building. This is because the installation required a major remodeling work.

Since the conventional lifting device has a semi-self-supporting structure, it is possible to perform work in the building such as mounting a structural material supporting a horizontal load on the building side, mounting a boarding door on the building side, and assembling the lifting device on site. It was expensive because of the large number. This is because the semi-standing structure makes it impossible to assemble the completed lifting device at the lifting device manufacturing plant.

The present small-sized lifting device is expensive to install, costs maintenance and inspection, and in the unlikely event that he cannot escape by himself, there is a lot of work on the new building site, existing building Due to reasons such as the difficulty of additional installation in As the aging society approaches, there is a need for a low-price, safe, and convenient elevator for a small number of people. In view of such conventional problems, the object of the present invention is extremely safe with no risk of a car falling, easy to install in a new building, and inexpensive to additionally install in an existing building with a small building remodeling work. It is to provide a structure of a lifting device for a small number of people.

[0012]

In order to achieve the above-mentioned object, the elevator for a small number of people of the present invention arranges one set of square screw shafts near any one of the columns of the car. ,
Fasten the female screw housing of the square screw shaft set and the motor with a reducer for raising and lowering the car to the suspension frame that is kept horizontal with the roller guide that contacts the column,
The floor of the car is mounted on this suspension frame via a vibration damping and soundproofing member (or vibration damping and soundproofing equipment), and the posture of the car is held by a plurality of car posture holding rollers attached to the car using the columns as guideways. Rotate the female screw gear of the assembled type square screw shaft set with the drive gear of the motor with reduction gear installed in to raise and lower the car.

When the car of the lifting device stops halfway, a small gear (pinion) meshing with the drive gear of the car lifting motor is manually operated so that the car can be lowered to the outside of the car by itself. Alternatively, the car is moved up and down by rotating it with a DC motor that runs on a battery. earthquake,
An emergency exit and a ladder will be placed on the side wall of the car in order to allow the car to escape from the car in an emergency when it is prone to panic such as a fire. A counterweight that will be a hindrance when escaping in an emergency is placed in the back of the room.

To reduce the size of the motor and the screw shaft, a counter balance device is used to reduce the cost and reduce the power supply capacity. Therefore, the installation position of the wire rope guide wheel is set at a low position, the number of structural materials is reduced, and the cost is reduced by shortening the wire rope.

In the square screw shaft type lifting device, the height of the square screw shaft is sufficient up to the floor when the car is raised, but in the present invention, in order to secure the installation dimensions of the car side door and the boarding door, the car To prevent the car from collapsing by lengthening the pillars on the door side,
The boarding door will be supported by a car support frame.
That is, of the four pillars that support the car, the two pillars on the car door side are made higher than the car ceiling position of the car ascending limit, and the car posture holding rollers using the pillars are provided at the car ceiling and the lower part of the car. In addition, in order to obtain the positional accuracy of the boarding door door and the car door, the boarding door door suspension rail mounting member and the boarding door door lower guide mounting member are fixed to the front column, and the boarding door door suspension rail and the boarding door door are fixed to this. Install the lower guide. Since both the car door and the boarding door are accurately positioned by the car support frame, positional accuracy of the boarding door and the car door is ensured.

In order to significantly reduce the manufacturing cost, an assembled type square screw shaft (or an assembled type square screw shaft) which is light and inexpensive to manufacture is used for the square screw shaft (or trapezoidal screw shaft). Since the assembled type square screw shaft has a structure in which a square rod or the like is wrapped around a steel pipe and welded, it does not need to be cut and can be manufactured at low cost. In addition, since it is light, material handling (material handling, material movement) is easy, assembly work time is short, and cost reduction effect is great.

[0017]

The lifting device for a small number of people according to the present invention has a structure in which the car is pushed up by the square screw shaft, so that there is no danger of falling and it is extremely safe. According to the lifting device for a small number of people of the present invention, the car is lifted by rotating the female screw gear of the square screw shaft set having the same principle as the square screw jack (daruma jack). Therefore, when the rotation is stopped, the lift is stopped and the car is dropped. There is no such thing. In the drum-type wire-winding type, the car falls when the wire is cut, but in the lifting device for a small number of people of the present invention, since the lead angle of the square screw is set within the friction angle, the car is supported by the square screw shaft and the car does not fall So it's extremely safe. Also, in the event of an emergency such as an earthquake or fire, you can leave the car by yourself without the help of others.

A female screw housing of a set of square screw shafts and a motor with a reducer for raising and lowering a car are fastened to a suspension frame which is kept horizontal by a roller guide which comes into contact with a support, and a vibration damping and soundproofing member (or Since the structure is such that the car is attached via the vibration damping and soundproofing equipment, the sound and vibration generated in the drive unit is blocked and does not enter the car.

The structure of the car door and the boarding door is regulated by the car support frame, so that the door can be installed easily. The gap between the doors can be reduced, making it easier to get in and out of a wheelchair.

Significant cost reductions can be achieved by using the assembled square screw shaft. Since the mounting position of the counterbalance device is lowered, the cost of the pillar material and the cost of the wire rope are reduced, and the cost can be reduced.

Since the lifting device has a completely self-supporting structure, it is possible to perform integrated production of finished products at the factory, and it is possible to reduce the cost due to mass production. Also, since the installation work in the building is small and the contents of the work are simple, the construction work time at the building site is short, and the cost can be reduced.

The door suspension rails supporting the boarding doors and the door lower guides are fixed to the car support frame by connecting members so that all the doors are held by the lifting device, and four columns are used as a skeleton for vertical load and horizontal load. Since it has a completely self-supporting cage support frame, it can be easily installed in the existing building and cost can be reduced.

Since the structure is simple, there are few failures. In addition, maintenance costs are low because inspection and maintenance are easy.

As is apparent from the above description, according to the lifting device for a small number of people of the present invention, since the structure is such that the female screw gear of the square screw shaft set is rotated to raise and lower the car, the same principle as the square screw jack is used. If the lead angle of the square screw shaft is set within the friction angle, even if the brake of the motor with reduction gear with brake does not work, there is no risk of the car falling even if the drive gear falls off, which is extremely safe. You can rest assured that you can raise or lower the car manually or with a starter motor even in the event of a power failure or failure. Since it has an emergency entrance and ladder, you can rest assured that you can use the ladder from the emergency entrance door to get out of the car even when you need to evacuate due to an earthquake or fire. Therefore, even if the lifting device breaks down, it will not be trapped in the car, and it will not be necessary to put another person in a private house at night, on holidays, or when a woman is alone, so it is safe and safe for crime prevention. Since the angle screw type personal house lifting device of the present invention is not likely to fall, it is not necessary to use safety equipment such as a double winding wire rope, a governor, a catcher, and a shock absorber unlike the drum hoisting type private house lifting device. It is possible to significantly reduce the cost. In addition, maintenance costs are reduced because almost no specialized technical skills are required for inspection and repair. Further, by using the assembled square screw shaft, it can be manufactured at extremely low cost. Since the elevator for a small number of people of the present invention has a structure for pushing up the car, the height of the car supporting frame may be lower than that in the case of pulling up the car, so that there is an advantage that less steel is used and the cost is reduced. Since the car door and the boarding door are positioned by the car support frame, door installation accuracy is improved and malfunction of the door is eliminated. In addition, the size of the gap between the car door and the boarding door can be reduced, and the wheel of the wheelchair can be prevented from falling, which is safe. Since a fully self-supporting car support frame structure is adopted, the finished product can be manufactured in the factory almost regardless of the building structure, so the manufacturing cost can be reduced. In addition, since it is a completely self-supporting structure, it can be easily added to an existing building as an elevating device for individual houses. Since it uses a suspension frame, it absorbs sound and vibration caused by the meshing of the drive motor and gears and does not enter the car, which is a problem. With the structure of the lifting device for a small number of people of the present invention, it is possible to provide a convenient lifting device that is safe, quiet, and safe at low cost. Through this, it is possible to contribute to the comfort of home life, and in particular, to the creation of comfortable lives in the aging society.
