Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an elevator and a method for installing the elevator.

[0002]

2. Description of the Related Art Conventional rope-type elevator installation methods are:
Use the fixed scaffold assembled with a single pipe or a movable scaffold such as a gondola, etc. to mount, pipe, and wire each component of the elevator equipment, that is, the landing entrance / exit device, shock absorber, guide rail, bracket, and hoistway equipment. Carriers (car frames, car rooms) were assembled on the top floor, counterweights were assembled on the bottom floor, and wire ropes for hoisting were installed, and the work scaffold was removed to start operation.

However, installation workability and efficiency are poor,
Due to problems such as high worker momentum, it is common to drive the hoist of the main body without using a fixed scaffold, and to install guide rails and door devices using the permanent car frame and floor as scaffolds. It is becoming.

The installation of hydraulic elevators and rope-type elevators without a machine room, which has recently attracted attention, has generally been performed by a method using a fixed scaffold (installation method in the case of a rope-type elevator).

[0005] This construction method is carried out from the beginning by using the car frame 1 of the elevator car as shown in Fig. 12 without using the work scaffold as described above. Done.

(1) The hoisting machine 13 lifts the car side, the counterweight side, and the two guide rails, each of which is lifted and connected sequentially at the lowest floor, to unify the entire height of the hoistway. Is fixed to the floor 4 or ceiling hook of the machine room, the guide rail is fixed to the shock absorber at the lowermost part, and the first and second brackets are installed from below to fix to the building.

(2) Carrier 7 and counterweight 8 at the lowest floor
And the hoist 13 lifts the counterweight 8 to the top floor, and hangs the hoisting wire rope 9. Next, Carrier 7
Work floors 10 and 11 are provided on the upper and lower parts of the car frame 1, respectively.
Attach.

The lower floor 10 is a permanent floor on which safety equipment such as a handrail 12 is installed. Upper work floor 11
Is used only at the time of installation, and is used to mount guide rail brackets that are not yet fixed and to measure rail gauges.

(3) The car frame 1 of the elevator transporter 7 is moved up and down along the guide rails 2, and the car frame work floor 1
The operator places the workers on 0 and 11 to set the components of the elevator equipment, that is, the guide rail brackets, install the landing entrance / exit device, install the equipment in the hoistway, and perform installation work such as piping and wiring. The lifting and lowering of the transporter is operated by an elevator hoisting machine 13 by an operator's operation, and is equipped with safety devices such as a governor, an emergency stop, a shock absorber, and operates at a low speed.

According to this method, as compared with the installation using a fixed scaffold, it can be moved to any place in the elevating direction and can be installed. Good quality installation is possible with less labor.

[0011]

However, there are the following problems. With the advancement of construction technology and the shortening of the period until delivery of customers, it is required to further shorten the elevator installation period. In addition, management of the installation work jig and reduction of transportation work are required.

In the installation method using the main body of the rope type elevator described in the prior art, the upper work floor 11 installed on the carriage 7 is necessary only during the installation work, and is assembled when the car frame 1 is assembled. After work, remove it and return it to the factory. After inspection, reuse it at another site. Therefore, problems such as man-hours required for installation and disassembly, transportation costs, and an increase in storage space in the factory have been pointed out, and a construction method that can be installed without using the upper work floor 11 has been demanded.

The reason why the upper work floor 11 is necessary is that, as shown in FIG. 13, the upright frame 23 of the carrier is usually provided on the front surface of the guide rail 2 for the carry, and the lower work floor shown in FIG. This is because the tooth surface position of the guide rail 2 cannot be accurately grasped from 10.

As shown in FIG. 13 [(a) is a longitudinal sectional view of the hoistway, (b) is a transverse sectional view of the hoistway], the hoistway wall 16 is a concrete structure, and the back of the rail and the hoistway wall are provided. The hole 18 of the anchor bolt 20 for mounting the rail bracket 19 cannot be drilled (performed with an electric drill or the like) on a bank where the distance 18 is small.

The reason for this is that when the hoistway is narrow, drilling of the anchor bolts 20 is obstructed by the upright frame 23 and the drill cannot be arranged perpendicular to the wall. Further, in the above construction method, the range in which the transporter can be lifted is limited to a range slightly above the portion where the guide rail 2 is fixed to the building by the bracket 19. (If it rises too much, the guide rails are not fixed and the transporter becomes unstable.) That is, the guide devices 21a and 21b of the transporter 7 are provided at the upper end and the lower end portion of the car frame 1, but the guide rails 2b
When the brackets 19a and 19b are fixed and the guide rails 2a are connected by the fixing plate 22 and the bracket 19c is not fixed yet, the transporter 7 moves the upper guide device 21a between the brackets 19b and 19c. Is that you can only go up to the position. (At that time, the guide rail 2a becomes a cantilever.) At such a height, it is impossible to measure and fix the rail gauge 15 at the position of the bracket 19c on the lower work floor 10 of the transporter 7; The upper work floor 11 is required.

[0016] For hydraulic elevators and machine room-less elevators, there is a demand for an installation method that does not use fixed scaffolds in order to improve work efficiency. When a hydraulic elevator is installed using a car frame and a floor, a rail for a hydraulic jack is not fixed, so that a drive by a hydraulic device is not performed and a separate drive device is required.

When the hoist is attached to the upper part of the hoistway in a machine room-less elevator, a drive device is required separately as in the case of the hydraulic elevator because the hoist cannot be driven by the permanent hoist. In those cases, when the weight of the work car increases, there is a problem that the elevating device becomes large, and a construction method that can be performed without using the upper work floor 11 is also required. SUMMARY OF THE INVENTION An object of the present invention is to provide an elevator and an elevator installation method capable of eliminating the need for an upper work floor installed in a conventional car frame.
