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.

[Conventional technology]

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 lifts and lowers the temporary car to keep the existing elevator intact during the remodeling period. It is proposed that the elevator service the floors.

Figure 3 shows this proposed temporary elevator.

In the figure, (1) is a hoistway, (2) is a companion machine room provided above this hoistway (1), and +31. +41 is the machine room (

(6) is a control panel that controls the hoisting machine (3). (8)
The hoistway (1) was replaced by the existing one (not shown).
This is a newly installed car that is being assembled inside the building and is fixed to the top of the hoistway (1). (9) is a counterweight that has been used in existing elevators, and will be used in both temporary elevators and new elevators. aO is a three-sided frame, Q

These are guide rails for cars and counterweights that were used in existing elevators, and are also used in temporary elevators and new elevators. (102).

(103) is a shock absorber that is also used in existing elevators, and also in temporary and new elevators.

(111) to (120) indicate the 1st to 10th floors served by the existing elevators.

(5th), one end was placed on the floor of the 9th floor (119), and the other end was placed on the support beam (22) attached to the front wall of hoistway +11.
A temporary machine stand supported by s) prevents door 0 of the landing on the 9th floor (119) from fully closing. (Tsukuda) is a temporary hoist placed on this machine stand (5th).

(24s) is the work floor supported by this support beam, and the basket (
8) C (130) used for assembly is on the 9th floor (119)
A partition door installed vertically in the building covers the entrance to the 9th floor (119) and prevents two people from entering the hoistway.

The temporary elevator shown in Figure 3 is a newly constructed elevator that is currently being assembled.
A hoisting machine (3S) is installed in the lower hoistway (11) than 8), so it seems to be a new installation (even though 81 is being installed).

The temporary elevator was in operation (on the 8th) to service the 1st floor to the T floor.

[Problems that the invention solves]

By the way, the first machine platform (58) protrudes to the ninth floor (119), so the door Oa of the first landing cannot be closed.

For this reason, the entrance on the 9th floor is always open while the machine platform (5θ) is installed, and there is a risk of people entering through the entrance on the 9th floor and getting caught in the hoisting machine (3θ). However, it is necessary to install a separate partition door (15r:n) that satisfies fire resistance to prevent intrusion.Therefore, there is a problem that the cost of modification work is high.

The purpose of this invention is to eliminate the partition door and reduce the cost of remodeling work.

[Means to try to solve problems]

The temporary elevator according to the present invention is used when remodeling an existing elevator into a new elevator by removing parts or installing new parts, and the machine platform is installed anywhere in the hoistway from the moving path of the first landing door. A temporary hoist was installed on this machine platform to service the floors that were previously serviced by the existing elevator.

[Effect]

In this invention, since two machine stands are housed in the hoistway, the door of the landing nearest to one machine stand can be closed. This landing door can prevent people from entering the hoistway.

〔Example〕

FIGS. 1 and 2 show an embodiment of the present invention.

In the figure, the same reference numerals as in FIG. 3 indicate the same group.

(30s) is the north support beam installed parallel to the sill t13 on the hoistway (1) wall below the 9th floor (119), and the support beam (
228). One end of (31B) is supported by the support beam (22s), and the other end is the door t1 of the landing on the 9th floor.
There is a temporary machine stand located on the hoistway 111 side of Z and supported by a support beam (30 days). This machine stand (31st)
A hoisting machine (3B) and a control panel (6s) are installed. (62nd) is a flooring material that fills the space between the machine platform (31B) and the wall of the hoistway (1).

In the above example as well, during the remodeling period, a temporary elevator was operated to handle traffic within the pill, and one machine (31s) was installed.
Because it is stored inside the hoistway (11).

The landing door α2 can be closed. Furthermore, the second landing door has an interlock mechanism and can be closed without the need for special locking equipment (not shown).

Therefore, there is no need to install a new partition door.

A temporary hoisting machine etc. is installed at the door of the existing elevator landing to prevent people from entering the temporary machine room, and there is no need to prepare a special lock. Since the door to the landing can be opened and closed, the cost of remodeling work can be reduced.

〔Effect of the invention〕

As described above, the present invention relates to a temporary elevator used when remodeling an existing elevator into a new elevator by removing or newly installing parts of the existing elevator.

A machine platform is installed on the inside of the hoistway 1, rather than the movement path of the landing door.
A temporary hoist will be installed on this machine platform to service the floors that were previously serviced by the existing elevator.7?
Therefore, the doors of the landing can be opened and closed without being blocked by the machine platform 9, and unauthorized persons can be prevented from entering the hoistway without installing a separate partition door.

[Brief explanation of drawings]

FIGS. 1 and 2 show an embodiment of the present invention. FIG. 1 is a vertical cross-sectional view of the hoistway showing the main parts, and FIG. 2 is a cross-sectional view taken along the line ■--■ in FIG. 1. The third section is a longitudinal sectional view of the hoistway showing a conventional temporary elevator. In the figure, (1) is the hoistway, (3a) is the hoisting machine, α2 is the landing door, (31θ) is the machine platform, (100) is the guide rail for the car, and (101) is the guide rail for the counterweight. (111) to (120) indicate the 1st to 10th floors. Note that the same reference numerals in the two figures indicate the same group or corresponding parts.

Claims (1)

[Claims] Used when converting an existing elevator into a new elevator by removing all or part of it except for the guide rail and replacing it with new parts or adding new parts, from the hoistway of the existing elevator to each floor. A landing door that opens and closes the entrance leading to the landing, a machine platform supported by the hoistway wall and arranged inside the hoistway from the travel path of the landing door, and a temporary hoist mounted on this machine platform.
