Description

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

[Prior art]

First, modification of a conventional existing elevator will be described with reference to FIGS. 5 and 6.

Figure 5 shows the existing elevator, and in Figure 1, (1) is a hoistway, (2) is a machine room provided above this hoistway (1), +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), and (7) is the hoisting machine (
3), a main rope wrapped around a deflector wheel (4), with a heel (8) at one end and a counterweight (9) at the other end.
) is installed and the elevator is moved up and down inside the hoistway f1) (8)
This service is provided from the 1st floor (111) to the 10th floor (120). αυ is a three-sided frame.

02 is the landing door that opens and closes the entrance, α3 is the threshold that guides this landing door + 13, (SO) Height frame, '
100) and (101) are guide rails for the car and counterweight.

(102) and (103) are also buffers.

Next, FIG. 6 shows a new elevator in which a part of the existing elevator shown in FIG. 5 has been replaced. Here, it is rare that all parts of an existing elevator are replaced. In FIG. 6, parts with the same reference numerals as those in FIG. 5 indicate that existing products will continue to be used, and parts to be replaced and newly added parts are shown with raJ attached to the numerical code.

In other words, the parts that need 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).

The parts to be added are 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 (5a) is attached;
a), the root protection 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) to prevent noise from being transmitted to the living room (not shown) near the machine room (2). The central part of the machine stand (5) is raised, and the vibrations generated from the second hoist (5a) are not directly transmitted to the machine stand (5).

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

Also, some of the equipment on the control panel (6a) is worn out.

Usually, it is replaced with a new control panel (6a) in order to have more functions than the conventional one as the control density improves.

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 (8). Therefore, the weight of the new heel (8a) will not be increased or decreased, and the existing heel (9) will be used as is.

As yet, the three-sided frame aυ and landing door α have not been replaced, and are usually only repainted. For the threshold αj, the existing product is often used as is.

Next, we will discuss the modification 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 (105). Next, disassemble the heel (8) and remove it from the hoistway (1).
Remove the car frame (80) from the main rope (7). This main rope (7)
is removed from the hoisting machine (3) and diverter wheel (4) and lowered into the pit, and further removed from the counterweight (9) and removed. In addition, the 2nd hoisting machine (3) and the control panel (6) are also located in the machine room (2).
Remove from.

Next, parts for the new elevator that were previously brought to the top floor will be installed.

First, in the second machine room (2), a floating stand (14a) is placed under the machine stand (5). A hoisting machine stand (15a) is placed on this machine stand (5) via an anti-photo rubber (16a), and a hoisting machine (5a) is placed on this hoisting stand (15a). The control panel (6a) will also be brought in and predetermined connections will be made. Next, install a scaffold (not shown) in the hoistway (1) and assemble the heel (8a) in the same manner as in the normal installation work. Next, the main rope (
7a) around the hoisting machine (6a), and attach one end to the car frame (8a).
0a), attach the other end to the counterweight (9).

Slightly raise the balance weight (9) and return it to its normal position.

Put the basket (8a) into operation.

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

[Problem that the invention seeks to solve]

As mentioned above, after lowering the counterweight (9) of the existing elevator, remodel it into a new elevator,
It took about two weeks to get it back up and running again. During this period, transportation within the building had to rely on stairs, causing great inconvenience to those involved. The present invention aims to alleviate such inconvenience for those involved.

[Failure to solve the problem]

In the temporary elevator according to the present invention, when remodeling an existing elevator into a new elevator by removing parts or adding new parts, a temporary hoist is installed in the hoistway, and this hoist is used to move the temporary car. The elevator is raised and lowered to service a portion of the floor that was previously serviced by the existing elevator.

[Effect]

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

〔Example〕

1 to 4 show an embodiment of this invention.

In the figure, the same reference numerals as in FIGS. 5 and 6 indicate the same parts.

In other words, parts with a code consisting of numbers only indicate parts used in the existing elevator, parts with a code consisting of a number and RAJ indicate parts to be replaced or added to the existing product. Parts with symbols consisting of and rsJ indicate parts of the temporary elevator that will be used temporarily during the remodeling period.

In Figures 1 and 2, (3s) is the 9th floor (1
19) A hoist temporarily installed in a hoistway (1) of considerable height.

(5OS) is a hoisting motor, and (43) is a temporary deflection wheel.

(5S) is a temporary machine stand with one end placed on the 9th floor floor (119) and the other end in contact with the front wall of the hoistway (1).
68) is a temporary control panel installed on this machine stand (5S).

(7S) is a temporary structure that is wrapped around the hoisting machine (3S) and deflection wheel (4S), and has the existing heel (8) attached to one end and the existing counterweight (9) still attached to the other end. It is a main rope that moves up and down at a speed of about 30 to 45 meters per minute.

Here, we will discuss how to hang the main rope (7S).

While the existing heel (8) and counterweight (9) are still suspended from the existing hoist (3), first lower the counterweight (9) and support it with the buffer (103). . At this time, the car (8) is stopped at a position slightly higher than the top floor (120). Install a chain block (not shown) in the machine room (2), and use this chain block to
8), then remove the main rope from the heel (8).Next, while operating the chain block, lift the cage (8).
Lower it and stop it at a position slightly higher than the 7th floor (117). In this state, the temporary main rope (7S) is attached to the hoisting machine (
3S) and the deflector wheel (4S), and attach the heel (8) to the cut main rope (7S). When the car (8) is lowered and the 7th floor floor (117) is aligned with the 7th floor floor (8), the distance from the top of the car frame (80) to the bottom of the machine platform (58) (hereinafter referred to as the top (referred to as clearance) (TC)
Ha corresponds to the distance from the 98th floor (11B) 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 (
7S), it is possible to satisfy the above enforcement order.

(iss) is the hoisting machine stand where the hoisting machine (6S) is installed.

It is placed on a machine stand (5S) via a vibration-proof rubber (163). (228) The wall below the elevator entrance on the 9th floor (119) and the hoistway (1) facing this wall
The other end of one machine stand (5S) is supported by support beams fixed to the wall. (233) is the 10th floor (
These are support beams fixed to the hoistway (1) wall of the entrance and exit 50 to 100 centimeters lower than 120) and the wall facing this wall. (248) is the work floor supported by this support beam (2!+13).

In Figure 3, (300) is the existing call button.

(5u1s) is well known in the call registration circuit, so its details will be omitted. (311S) to (3178) are on the 1st floor (1
11) - Nominal relay contacts corresponding to the 7th floor (117),
(331) is a normally open contact for the lift starting button, which is provided at the heel (8) of the existing elevator. (332) is the normally closed contact, and (333) is the normally open contact of the lowering start button, which is provided on the car (8). (334) is also a normally closed contact.

(4008) is a control power supply, (+) and (-) are bus bars,
(402) is a safety circuit used in the existing elevator, and (4oss) is a contactor that biases the hoisting motor (308) in the upward direction.

(40518) is its normally open auxiliary contact, (4048)
is a contactor that urges the hoisting motor (3OS) in the downward direction,
(40418) is its normally open auxiliary contact, (405
8) is a stop relay.

(4051S) is its normally open contact, and (40528) and (4053S) are its normally closed contacts. (4118)
~ (4173) is a temporary construction hem (8) on the 1st floor (1
11) - This is a position switch provided in the hoistway to stop at the T floor (117).

As shown in Figures 1 to 3, once the temporary elevator is installed, it is independent of the equipment in the machine room (2).

Also, even if the new heel (8a) is not installed, the 2nd hoisting machine (5S) will be assembled and the heel (8) will be on the 1st floor (111).
This service provides lifts up and down the 7th floor (117).

That is, when a call button (SOO) is pressed, a corresponding call is registered. If the call for the first floor (111) is registered, the relay contact (311S) is closed. When the descent activation button (334) is pressed.

The contactor (4048) is energized and the heel (8) is lowered. Also, the normally closed contact (40413) is closed and the contactor (
4048) is self-maintaining. The basket (8) is on the first floor (111
), the position switch (4118) is closed,
Stop relay (405S) is (+) - (411S) -
(3118) - (4053) - (-) is energized by the circuit. This energization opens the normally closed contact (40538) and deenergizes the contactor (4048).

Due to this de-energization, the hoisting motor (308) is also de-energized and the shaft (8) stops on the first floor (11).

The same applies to the 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 (6a), floating stand (14a,), hoisting machine stand (1
5a) and the anti-vibration rubber (+6a) are replaced with existing products in the same manner as in the conventional example shown in FIGS. 5 and 6. The new heel (8a) is assembled by a worker on the work floor (248), and is fixed slightly above the 10th floor (120). During this assembly process, traffic within the building will be handled by temporary elevators. Also, remodeling work will be carried out directly above the temporary elevator, but there are 2 working floors (24s), so 1
For example, even if a screw falls, it will not fall into the heel (8).

Next, if you have finished replacing the parts with new ones.

The temporary elevator is stopped, and as shown in FIG. 4, the counterweight (9) that had been used in the temporary elevator is placed on the shock absorber (io5) again and the main rope (7S) is removed. Furthermore, the car (8), the car frame (aO), and the hoist (
ss'), deflector wheel (48), machine stand (58), control panel (68).

Hoisting machine stand (15s), anti-vibration rubber ('16.9), support beam (228).

(2SS) and work floor (243) are removed. After that.

Wrap the newly installed wire (7a) around the hoist (6a) and deflection wheel (4a), and attach the car (8a) and counterweight (
9) Hang it.

When the car (8a) is accurately placed on the floor (120) on the 10th floor, the bottom surface of the counterweight (9) is placed on the buffer (103).
It is located above and separated by a predetermined distance from. 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. Upper machine (58), control panel (6
S) etc. can be placed on the machine stand (5S) in advance. Therefore, the period for installing the temporary elevator is 1
Pull the machine platform (5S) into the hoistway +11 and attach the support beam (2
28) and the work time required to attach the main rope (7S) is the same. Also, how long will it take to remove the temporary elevator?

Removal of the machine stand (5S) on which the hoisting machine (3S) etc. are mounted and the support beam (228), removal of the cage (8), and attachment of the main rope (7a) to the counterweight (9). υ is equal to y for the time required to complete the task. However, since many of these tasks can be performed in parallel, the removal task can be completed in a short time.

Therefore, according to the above 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 pill is by stairs.

Furthermore, if temporary elevators are installed and removed during the night when they are less frequently used, then
It can be remodeled with little inconvenience to customers.

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 addition, in the above embodiment, the heel of the existing construction I/peter was used for the car of the temporary elevator, but a heel exclusively for temporary construction 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.

Yet again. In the above embodiment, the basket (8) was modified, but the basket (8) was not modified and other parts were modified.

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

〔Effect of the invention〕

As stated above, this invention provides for installing a temporary hoist in the hoistway when converting an existing elevator into a new elevator by replacing all or part of it except for the guide rails or adding new parts. The hoisting machine was used to drive a temporary car to service some of the floors that were previously serviced by the existing elevator, 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.
