び、エネルギ節約の観点から特開昭61−136889に記載さ
れるように釣合い重りを用いる構造が知られている。Conventionally, in this type of fluid pressure elevator, the car is directly connected to the plunger of the fluid pressure cylinder, or the plunger,
Indirectly connected via pulleys and ropes, the car is lifted by the push-up motion (plunger extension motion) of the pressure fluid, and the car is lowered by the plunger push-down motion (plunger contraction). Therefore, from the viewpoint of reducing the force acting on the elevator and saving energy, there is known a structure using a counterweight as described in JP-A-61-136889.

低下する問題があつた。In the above-mentioned conventional technology, the elevator car is lifted by the push-up operation of the plunger of the fluid pressure cylinder, and it is necessary to increase the plunger diameter in view of the buckling strength of the plunger.
The pressure fluid becomes relatively low pressure (10 to 30 kg / cm 2 ), and along with this, hydraulic equipment such as flow control valves and fluid pressure pumps also become large, resulting in high cost and low energy efficiency. In addition, a structure has been proposed to reduce the required power by using a balance weight to balance the weight of the car's own phase.In this method, the balance weight is reversed in addition to the space in which the car moves up and down. A space for moving in the direction is needed, and the hoistway area increases. That is, there is a problem that the space factor is lowered.

を有効に利用する流体圧エレベータを提供することにあ
る。It is an object of the present invention to provide a fluid pressure elevator in which the hydraulic equipment is downsized and the cost is reduced, the force for driving the car is reduced, and the lifting space is effectively used.

に動作することを特徴としている。A car that is controlled to control the pressure fluid supplied to and discharged from the fluid pressure cylinder and is moved up and down along the elevating frame member, one end of which is fixed to the elevating frame member and the other end of which is mounted on the plunger of the fluid pressure cylinder. In a fluid pressure elevator having a rope fixed to a car through a pulley provided on an upper portion of a frame member, a fluid pressure cylinder attached to a lower portion of an elevating frame member and an upper portion with respect to the fluid pressure cylinder. It is characterized in that it has a plunger mounted so as to extend and a weight provided on the plunger, which is slightly lighter than twice the weight of the car, and that the plunger operates in a contracting direction when the car rises.
乗りかごの上昇時にプランジャが縮小方向に動作する
こと、および重りを乗りかご重量の２倍より若干軽くす
ることにより、流体圧シリンダの縮む方向を乗りかごの
上昇方向とし、流体圧のエネルギ、および重りの自重を
乗りかごの上昇させる力とすることができる。By moving the plunger in the direction of contraction when the car moves up, and by making the weight slightly less than twice the car weight, the direction in which the fluid pressure cylinder contracts is the direction of car uplifting, and the fluid pressure energy, and The weight of the weight can be used as the force for raising the car.
よって、プランジャは常に引張り力を受けるようにな
り、座屈を生じる恐れがなく、プランジャ径を小さくで
き、圧力流体として比較的高圧のものを採用できる。Therefore, the plunger always receives a tensile force, there is no risk of buckling, the plunger diameter can be reduced, and a relatively high pressure fluid can be used.
また、重りはそのおもさが乗りかごの自重相当分（乗
りかご重量の２倍）より若干軽いので、乗りかごが自重
で下降できるようになるから、ポンプ動力も小さくでき
る。Further, since the weight of the weight is slightly lighter than the weight corresponding to the own weight of the car (twice the weight of the car), the car can be lowered by its own weight, so the pump power can be reduced.

なくし、乗かご１を、減速，停止させる。First, when raising the car 1, the hydraulic pump 12 is driven by the motor 13 according to a command, and the pressure fluid from the pump 12 is supplied to the upper part of the cylinder 10 while being controlled. Therefore, the plunger 11 moves while accelerating in the contracting direction.
The movement of the plunger 11 is transmitted to the car 1 via the rope 19 and the pulleys 16, 17 and 18, and the car 1 is guided by the boarding / alighting frame member 2 to accelerate and accelerate. During this time, the weight 20 attached to the plunger 11 is balanced so as to reduce the weight of the car, and the weight of the car 20 is slightly less than twice the car weight so that the car can descend by its own weight. Therefore, the pump power can be reduced. When the stop target position approaches, the flow rate supplied to the cylinder 10 is reduced, and the car 1 is decelerated and stopped.

It is transmitted to the car 1 balanced by the weight 20 via the car 8. The car 1 descends due to the weight difference from the weight 20. Then, when the car 1 approaches the stop target position, the flow rate of the fluid to the fluid pressure cylinder 10 is reduced, and the car 1 is decelerated and stopped.

なる。According to the above-mentioned configuration, the load due to the own weight of the car 1 exerts a force in the extension direction of the plunger 11 of the fluid pressure cylinder 10, so that there is no force in the direction of contraction of the plunger unlike in the conventional case, so that buckling The problem goes away. Therefore, the diameter of the plunger can be made smaller, and the plunger side can be made to have a bodice. The miniaturization of the cylinder allows the use of high-pressure fluid, and hydraulic equipment such as control valves for tanks and pumps. It is possible to greatly reduce the size. Also,
You can save space as a whole. further,
By adopting a high pressure fluid, the pressure loss in fluid equipment is relatively small and energy can be saved. In addition, downsizing the equipment saves labor during installation and assembly, and reduces equipment costs.

When trying to attach a weight to a conventional plungeer, the plungeer length must increase the weight mounting space. However, according to this method, the weight can be attached by slightly modifying the conventional fluid pressure cylinder.

Instead of the weight, another cylinder 10 is provided with an accumulator 24 to connect the plunger 11 to the plunger 22 to obtain a force equivalent to that of the weight by fluid pressure. As a result, the set value of the pressure of the accumulator 24 can be changed, so that the force can be set arbitrarily.

Since parts, space, and work are unnecessary, work man-hours and cost can be reduced. In addition, space can be saved, and the entire system can be downsized, resulting in a significant cost reduction.
