Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an installation method for an elevator, and particularly to an installation method suitable for an elevator driven by a drum hoist.

[Conventional technology]

A conventional method for installing an elevator driven by a winding drum type hoist is as described in Japanese Patent Application Laid-Open No. 60-52483. In other words, a scaffold is temporarily installed in the elevator hoistway, and a permanent pulley is attached to the upper part of the hoistway. A rope was placed, the main equipment of the elevator was connected to this rope, and the main equipment was hoisted to a predetermined position by operating a single-barrel hoisting rock.

[Problem that the invention seeks to solve]

Incidentally, the demand for elevators using drum-type hoisting machines is generally for small-sized buildings. When constructing such a small building, a 100V power supply is sufficient except for the elevator installation work, so the main contractor uses the power supply only for the elevators until the building is near completion20.
In many cases, 0V power is not drawn. For this reason, elevator contractors have had to draw in a separate temporary power source for elevator installation work, or have had to match the work schedule of the builder, which has caused problems in terms of economy and efficiency.

Therefore, in many cases, the conventional elevator installation method is
It is necessary to arrange for a separate power source using an engine, or to assemble temporary scaffolding at a fixed pitch in front of the hoistway. There was a problem in that it required a lot of trouble to temporarily construct and dismantle.

An object of the present invention is to provide an elevator installation method that allows installation work to be carried out regardless of the timing of installing an N source.

[Means for solving problems]

In order to achieve the above object, the present invention assembles a main car frame on the top floor of a hoistway, and uses this main car frame.

The brake of the 1-thigh spool-type hoist is momentarily released by suspending it via a pulley installed at the top of the hoistway using the main rope from the spool-type hoist installed near the bottom of the hoistway. The present invention is characterized in that various operations are performed while sequentially moving the main car frame downward by operation.

[Effect]

Since the present invention uses the above-mentioned installation method, the car frame can be lowered by its own weight by manually releasing the brake of the one-piece winding-truck hoisting machine in small steps. Even at sites where power is not available, various tasks can be carried out using the car frame, which is lowered by its own weight.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

Figure 1 is a work process diagram, in which the first step is to assemble a temporary work floor on the top floor of the hoistway. In other words, as shown in Fig. 6, a temporary work floor 3 is assembled using the materials brought to the top floor of the hoistway. Next, as a second step shown in FIG. 1, pulley attachment is performed.

This is done by attaching a Gooley bracket 1 using the temporary work floor 3 shown in FIG. 2 as a foothold, and attaching the permanent pulley 2 to this pulley bracket 1. Thereafter, as the third step in FIG. 1, the guide rails are erected.

In other words, the guide rail 4 carried into the hoistway 6 from near the bottom of the hoistway 6 shown in FIG. Pull upwards by the amount equivalent to the length of the minute. Next.

The work of connecting the lower guide rail of this lifted guide rail 4 and lifting it up to a height equivalent to one guide rail is repeated, and in the end, a pair of guide rails are installed on both sides of each floor entrance/exit 13. Install the rail.

The next fourth step is centering and fixing the guide rail, in which the guide rail bracket 5 is used to center and fix the guide rail to each floor surface of each floor entrance 13. The next fifth step is car frame assembly, in which the temporary work floor 3 assembled on the top floor of the hoistway is moved downward as shown in Figure 3, and the permanent car frame is constructed using the moved temporary work floor 3 as a foothold. Assemble 10 on the top floor. In parallel with this step, a winding drum type hoist 8 for permanent installation and a control panel 9 were installed in a machine room 7 formed near the bottom of the hoistway 6 as step v.6. After sending out the permanent rope from the upper machine 8 and suspending the permanent car frame 10 via the permanent pulley 2 in the seventh step, the temporary work floor 3 is dismantled in the eighth step.

The state at this time is as shown in FIG.

Next, in the ninth step of moving the car frame, the main car frame IO is moved to a predetermined position by manually operating the brake of the main installation winding drum type hoist 8 and releasing it inch by inch. As a tenth step, various works such as installation of entrance/exit parts and equipment in the hoistway (not shown), and wiring and connection work in the hoistway are performed. All the work in the hoistway is completed by repeating this brake inching operation and various works until the main car frame 10 reaches the lowest floor.

Finally, when the elevator power was turned on, the 11th
As part of the process, trial runs and adjustments will be made.

〔Effect of the invention〕

As explained above, the present invention comprises a permanent car frame on the top floor of the hoistway, and this permanent car frame is sent out from a single-carrying type hoist and hung on a permanent pulley.

The main car frame was lowered by its own weight by suspending the car frame by its own weight by gradually releasing the brake of the single-carry hoisting machine. Elevator installation work can be carried out without installing a separate power source even when the elevator is not drawn in.

Claims (1)

[Claims] 1. In the elevator installation method, which is carried out by moving the permanent car frame along the guide rail installed in the hoistway, a temporary work floor is assembled on the top floor of the hoistway, and this temporary work floor is used to install the elevator car on the hoistway. After attaching the permanent pulley to the section and erecting the guide rail, move the temporary work floor downward, and use this temporary work floor to assemble the permanent car frame,
After suspending the permanent car frame from the permanent trunk-type hoist installed near the bottom of the hoistway via the permanent rope provided through the permanent pulley, the temporary work floor was dismantled, and the above-mentioned A method for installing an elevator, characterized in that various works are carried out while sequentially moving the main car frame downward by gradually releasing the brake of a winding drum hoist for the main installation.
