Description

[Detailed Description of the Invention] The present invention relates to a lifting device used for raising and lowering people, luggage, etc., and particularly in the event of a fire in a high-rise building, hotel, etc. This invention relates to a device that is useful as a lifesaving lifting device that can be installed to rescue evacuees.

Various types of rolling lifting devices have been proposed in the past, but as the lifting stroke becomes quite long, the structure of all of them becomes extremely complicated, and many of them are also extremely expensive. For example, the ladder trucks of the Tomari Fire Department that are dispatched in the event of a fire in a high-rise building or hotel are extremely expensive, depending on the length of the ladder, and those that can be used for buildings over 10 stories are only installed in some areas. The current situation is that the number of disaster prevention measures is not sufficient.

The present invention has been made in view of these conventional circumstances.The purpose of the present invention is to provide a C-lowell with a simple structure, and even if the lifting stroke becomes high, the cost will not increase so much, and the cost will not increase by 1% in 1%. Elevating equipment useful for saving lives in the event of a fire in buildings, hotels, etc.: We will provide the following.

The lifting device of the present invention basically utilizes the relationship between the rack and the pinion gear.

Next, the elevating and lowering operations of the elevating device of the present invention thus constructed will be explained.

First, as shown in FIG. 1, in the lowered state of the elevating deck 4 with each hollow cylinder 2 and the support 3 contracted, power is turned on to each part, and the support 10 with rack is moved by the transfer device 16. It is fed out one by one, and when it reaches just below the pinion gears 5a and 5acD of the gear device group 5.e., the lift 18 is raised to lift up the struts 10 one by one, and the rack teeth 11a111a at the tips are engaged with the pinion gears 5a and 5a. match.

At this time, since the motor 8 rotates normally, the support 10 is pulled upward by the pinion gears 5a, 5a meshed with the rack teeth 11a, 11a, and first,
As shown in FIG. 3, the tip of the first racked support 1° pushes up the lower end of the support 3 which has been stored inside the innermost hollow cylinder 2a of each hollow cylinder 2. Then,
The elevating deck 4 is raised by approximately one rack-equipped column 10.

In this way, the other racked support columns 10
... are sent out one after another, these support columns 10 and ψ can be fully inserted into the desired hollow cylinder bodies 2 one after another, and are stacked continuously with the support columns 10 immediately above, and at the same time, each of the hollow cylinder bodies 2. −
... is pushed up and extended by the step portion 15a115a of the support column 10. Finally, as shown in FIG. 2, all the hollow cylindrical bodies 2... and the support columns 3 are extended, and the elevating deck 4 is brought to a desired height. In this state, people and cargo are placed on the elevating deck 4.

Next, in order to lower this elevating deck 4, the motor 8
First, remove the lowest rack-equipped column 10.
The pinion tooth hollow cylinder body 2 of the gear device group 5 . At this time, the support column 10 separated from the front pinion wheels 5a, 5a is received by the lift 18, and the lowering of the lift 18 causes the transfer device f! 1
6, and then returned to the original position tr[ by the chain conveyor mechanism 1γ of the transfer device 16. If this is carried out immediately, each of the hollow front bodies 2 . . . and the support columns 3 will all be retracted, and the elevating deck 4 will be returned to its original lowered position as shown in FIG.

In fact, to stop the lifting deck 4 at any point in the middle, simply stop the rotation of the motor 8. That is, by stopping the pinion gears 5a, 5a, the racked support column 10 is stably fixed.

Such rotational operation of the motor 8 may be performed by providing an operation switch (for example, one with switching functions such as forward rotation, reverse rotation, and stop) on the machine frame 1 side, but it is also possible to use a similar switch. It is also possible to provide it on the elevating deck 4 side so that it can be operated from the deck 4 side.

Similarly, people, luggage, etc. may be lowered from the elevator deck 4 at the lowered position by, for example, attaching a ladder or the like to the machine frame 1 in advance.

The use of the lift r* design according to the present invention cannot be particularly limited, but for example, as shown in FIG.
It can be installed on self-propelled objects such as hotels, etc., and is 1+ for high-rise buildings such as hotels! It is good to be able to move smoothly to 10,000 yen and use it as a means of evacuation in case of a fire, etc. For example, if the hotel is prepared in advance, a rescue system can be set up extremely quickly. In this case, a suitable number of guide rails 20 as shown in the drawings are provided on the wall surface of the building, with the same longitudinal force or in the horizontal direction, and these rails 20
・If the roll 21 and the like that have been taken up on the lifting deck 4 are slid together as shown in FIG.

The elevating device C can also be used on the platform of a fire truck, etc. In addition to being used for lifesaving purposes, it can also be installed underground in a part of a building that corresponds to an elevator room. , it is also possible to use it as an elevator. In addition, it can also be used as various cargo handling devices.

In addition, in the above embodiment, one rack-equipped column 1
0 approximately corresponds to one hollow cylindrical body 2, but as shown in FIG. 9, it may also correspond to several short support columns 10 with racks. This makes it possible to downsize the entire device.

Also, regarding the transfer device 16', instead of having a linear configuration, for example, as shown in FIG. It is also possible to smoothly transport a larger number of support columns 10, 10', 0.

As is clear from the above explanation, the following effects can be obtained by the lifting device of the present invention.

(A) The structure is simple and C can be manufactured at low cost even if the lifting stroke is quite long.

(b) The entire number rack can be assembled into a relatively small size, making it easy to move and use. In particular, in the event of a fire in a high-rise building such as a hotel, C can be quickly installed on the side of the building, providing great convenience for saving lives.

(C) By increasing the number of hollow cylindrical bodies and the number of rack supporting columns, it is possible to easily provide an extremely high lifting stroke without causing a large increase in cost. I can do it.
