Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a temporary elevator that can be used temporarily when an existing elevator is remodeled into a new elevator.

[Prior art]

First, we will discuss the modification of conventional existing elevators with reference to Figures 6 and 7. Figure 6 shows the existing elevator, and in Figure 9, (1) is the hoistway, and (2) is the upper part of this hoistway (1). Machine room located at +31. +41 is the hoist and deflection wheel attached to the machine stand (5) provided in the machine room (2), (6
) is the control panel that controls the hoisting machine (3), (71 is the hoisting machine (
3), the main rope is wrapped around the deflection wheel (4), with a heel (81) on one end and a weight (9) on the other end.
) is installed and it is possible to go up and down in the hoistway (1) (8)
1st floor (1111 to 10th floor (120)) 6I is a three-sided frame that provides K service, a2 is a landing door that opens and closes the entrance, αJ is a threshold that guides this landing door α2,
(80) Key and frame, (100).

(101) is a guide rail for the car and the counterweight, and (102) and (105) are also buffers.

Next, FIG. 7 shows a newly constructed elevator in which a portion of the existing elevator shown in FIG. 6 has been replaced. Here, it is rare that all parts of an existing elevator will be replaced. In Fig. 7, parts with the same symbols as in Fig. 6 indicate that existing products will continue to be used, and replaced parts and newly added parts are shown with raJ added to the numerical code.・.

In other words, the parts to be replaced are generally the hoisting machine (3a), deflection wheel (4a), and main rope (7), which are severely worn out.
a), a car (8a) and a car frame (80a).

In addition, the added parts include a floating stand (14) that supports both ends of the machine stand (5) in order to improve riding comfort and service.
a), a hoisting machine stand (15) to which the hoisting machine (3a) is attached;
a), the vibration isolating rubber (16a) provided between the hoisting machine stand (15a) and the machine stand (5), and the control panel (
6a).

These additional parts will be modified into a new elevator by installing floating stands (14a) at the bottom of both ends of the machine stand (5) so that noise will not be transmitted to the living room (not shown) near the machine room (2). In order to prevent the vibration generated from the machine stand (51) from being directly transmitted to the machine stand (5), and the machine stand (51) with its central part raised.

A vibration-proof rubber (16a) is interposed therebetween.

-1fC, the control panel (6a) has some wear and tear on the - disconnection equipment,
- Normally, as control density improves, the next control panel (6a) is replaced with a new one that has more functions than the previous one.

This is because the elevator heel (8a) is usually the largest size that can be accommodated in the hoistway (1).

The new heel (8a) is often the same size as the existing heel (81). Therefore, even if the new heel (8a) is installed, the weight of the counterweight (9) will not be increased or decreased. Existing products will be used as is.

Additionally, the three-sided frame α9 and the landing door α2 are not replaced, but are usually only repainted. For the threshold 03, the existing product is often used as is.

Next, let's talk about the remodeling work. First, parts to be replaced and additional parts will be transported to the top floor using the existing elevator. When the transportation is finished, the counterweight (9) is lowered and placed on the buffer (103). Next, disassemble Kato (81) and remove it from the hoistway (1).
Remove the car frame (80) from the main rope (7). This main rope (71
Remove it from the hoist (3) and deflection wheel (4) and lower it to the bit, and also remove it from the counterweight (9) and remove it. The first volume will also be removed.

Next, we will install the parts for the new elevator that was previously brought to the top floor.

First, in the second machine room (21), place the floating stand (14a) under the machine stand (5). Place the hoisting machine stand (15a) on top of this machine stand (5) via the anti-vibration rubber (16a). sow,
The K hoisting machine (3a) is placed on this hoisting machine stand (L5a). The control panel (6a) is also brought in and predetermined connections are made. Next, install a scaffold (not shown) in the hoistway (1) and assemble the heel (8a) in the same manner as in normal installation work.

Next, wrap the main rope (7a) around the hoist (3a). One end is attached to the car frame (80a) and the other end is attached to the 9-go weight (9). 1) Slightly raise the counterweight (9) and return it to its normal position to put the car (8a) into operation.

Next, the remodeling work is completed by removing the existing parts and lowering them using the newly installed heel (8a).

[Problem that the invention seeks to solve]

It took about two weeks to lower the balance weight (9) of the existing elevator as described above, convert it into a new elevator, and return it to operation again.

During this period, transportation within the building must rely on stairs.
It was a great inconvenience for everyone involved. The present invention aims to alleviate such inconvenience for those involved.

[Means for solving problems]

The temporary elevator according to the present invention is constructed by removing parts of an existing elevator or (l-1): When remodeling the elevator by adding new parts, a temporary hoist is installed on the floor of the building,
Additionally, a temporary barge car was installed inside the hoistway.
A temporary car is suspended and the main rope is wrapped around the hoisting machine via the return wheel so that it can be raised and lowered, thereby servicing the floors that were previously serviced by the existing elevator. be.

[Effect]

In this invention, a temporary elevator serves during the period when an existing elevator is being remodeled into a new elevator, so even if the remodeling work takes a long time, traffic within the building can be handled without any hindrance.

Lower the basket (8), align the floor (117) on the 7th floor with the floor on (8), and measure the distance from the top of the basket frame (80) to the bottom of the machine stand (5th) (hereinafter referred to as the top). It is called clearance.) (TCriili
This corresponds to the distance from the 8th floor (118) to the 9th floor (119).

Usually grows between 280 and 350 cm. This top clearance (TC) is stipulated by the Building Standards Act Enforcement Ordinance to be 120 cm or more, and as mentioned above, the main rope (
7θ), the above enforcement order can be satisfied.

(228) is fixed to the wall opposite the entrance of the hoistway (1) so that its upper surface is flush with the ninth floor (119), and supports one machine platform (58) with a support beam. (23s) is a support beam fixed to the hoistway wall and the wall facing this wall, which is 50 to 100 centimeters above the 10th floor floor (120). (24s
) is supported by this support beam (25g) and is a working floor.

In Figure 3, (500) is the existing call button.

(301s) is well known in the call registration circuit, so its details will be omitted. (3118) to (517B) are on the 1st floor (1
11) - Nominal relay contacts corresponding to the first floor (117),
(331) is a normally open contact for the lift starting button, which is provided at the heel (8) of the existing elevator. (552) is the normally closed contact, and (333) is the normally open contact of the lowering start button, which is provided on the car (8). (3541 is also a normally closed contact.

(400s) is the control power supply, (→ and ←) are the busbars,

It is a position switch.

As shown in FIGS. 1 to 3, when a temporary elevator is installed, it will be used regardless of the equipment in the machine room (2), even if a new elevator (8a) is not installed.

The hoisting machine (3rd) is busy and (8) is on the 1st floor (11th).

11th)-(405g)-day circuit. This energization opens the normally closed contact (4055s) and deenergizes the contactor (4041i), F! -ru. Due to this de-energization, the hoisting motor (30e) is also de-energized and the motor (81) stops on the first floor (111).

The same applies to the case of ascending operation, and the explanation will be omitted.

Remodeling work will proceed in parallel with the above-mentioned operation of the temporary elevator.

That is, in FIG. 4, the newly installed hoist (3a).

Control panel (Sa), floating stand (14a), hoisting machine stand (15
a).

The vibration isolating rubber (16a) is replaced with the existing one in the same manner as in the conventional example shown in FIG. 6 and the bore diagram. The new heel (8a) is assembled by a worker on the work floor (24s), and is fixed slightly above the 10th floor (120). During this assembly process, traffic within the pill will be handled by a temporary elevator. In addition, although remodeling work is being carried out directly above the temporary elevator, there is a working floor (24s), so even if screws fall, they will not fall (8). If you have finished replacing it.

The temporary elevator is stopped, and in FIG. 4, the counterweight (9) that had been used for the temporary elevator is again placed on the buffer (1 [13)], and the main rope (7th) is removed. Furthermore, a car (8), a car frame (80), a hoist (5e), a hoisting wheel (41g), (428), a machine stand (
5s).

Remove the control panel (68), support beams (22g), (23B), and work floor (24θ). After that, the main rope for new installation (
Wrap 7a) around the hoist (3a) and deflection wheel (4a), and hang the heel (8a) and counterweight +9). When the car (8a) is accurately placed on the floor (120) of the 10th floor, the lower surface of the counterweight (9) is located above the shock absorber (103) by a predetermined distance. The remodeling work will be completed by transporting the removed existing equipment and temporary equipment outside.

In the embodiments shown in Figures 1 to 4, traffic within the building depends on the stairs only during the period until the temporary elevator is installed and during the period when the temporary elevator is removed. 9 hoisting machine (3θ), control panel (68
] etc. can be placed in advance on the machine stand (5 days). Therefore, during the installation period of the temporary elevator, one machine platform (5 days) must be pulled into the hoistway (1), and the support beam (2
The work time required to fix the main rope (78λ) to the main rope (78λ) is approximately equal to the work time required for fixing the main rope (78λ) to the Removal of stand (58) and support beam (22s) and basket (8
) and the counterweight (9) of the main rope (7a)
The time required for installation is approximately the same. but.

Since many of these tasks can be performed in parallel, the removal task can be completed in a short time.

Therefore, in the above-described embodiment, the temporary elevator is used until the equipment and car in the machine room of the new elevator are installed, so it is possible to significantly shorten the period during which the only transportation within the building is by stairs.

Furthermore, if the installation and removal work of the temporary elevator is carried out during the night when the elevator is used less frequently, the remodeling can be carried out with little inconvenience to the customers.

In addition, since the 9th hoist (3rd) is installed on the 9th floor (119), the work space is wider compared to when it is installed in the hoistway fil, making it possible for many people to work on temporary construction. In particular, since the 2nd volume (3 days) is a heavy load, the wide work base is extremely advantageous for installation work.

Yet again. It is possible to install a temporary hoist in the machine room (2), but the two machine rooms (21 is on the top floor (120) and are usually connected by a narrow staircase (not shown). The work is extremely difficult.In the above embodiment, the work is easy because it is installed in the landing area.

Yet again. According to the above embodiment, the installation work is not limited to Saturdays and Sundays, but can be done even on five days a week, so there is an advantage that the work efficiency is good.

By the way, in the above example, the 7th floor (117) to 10
Since it is not possible to reach the floor (120) by a temporary elevator, we have no choice but to rely on the stairs. However, the 3rd and 4th floors are considered to be within the range that can be ascended and descended by stairs, which is acceptable.

In the above embodiment, an existing elevator car is used as a temporary elevator car, but a temporary elevator car may also be used.

Further, in order to reduce the weight of the hoisting machine of the temporary elevator and to facilitate installation work, the hoisting motor may have a small capacity by lowering the lifting speed.

Further I/ct7? : In the above embodiment, the basket (81) was modified, but the basket (8) was not modified and other parts were replaced.

For example, it can be used when replacing an existing hoist installed in a machine room.

FIG. 5 shows another embodiment of the present invention, and in FIG. 9, the same reference numerals as in FIG. 2 indicate the same parts.

In the figure, (5g) is a temporary machine stand, which is the first machine stand (51st) fixed to the floor (119) on the 9th floor and on which the hoisting machine (58) is placed, and this first machine stand.

Even with the device shown in FIG. 5, the intended purpose can be achieved, and the temporary machine stand can be folded down, making it easy to transport.

〔Effect of the invention〕

As described above, this invention is applicable to a hoisting machine installed on the floor of a building when converting an existing elevator into a new elevator by replacing all or part of it except for the guide rail or adding new parts. The main rope is wrapped around the shaft, and the main rope is installed in the hoistway and suspended through a reversing wheel.
Temporary cars were suspended and the existing elevator was used to service the L/'1'fc floor, so the temporary elevator could handle traffic within the building during the remodeling work.

This has the effect of reducing the inconvenience for elevator users.
