Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention relates to an improvement of an elevator installation device.

[Conventional technology]

Figures 3 and 4 show conventional elevator installation equipment. is a lifting hole for lifting the above-mentioned equipment, and is bored in the floor of the machine room 2. 4 is a lifting machine consisting of an electric chain block, and 5 is a hanging metal fitting, which is suspended from the ceiling of the machine room 2 via anchor bolts 6. 7 is the car side guide rail, 8
is the counterweight side guide rail, 9 is the counterweight,
10 is a hoistway.

A conventional elevator installation device is constructed as described above, and the work up to hanging a rope between the counterweight 9 and the car via a hoisting machine is generally performed in the following steps. That is, first, the hanging fittings 5 are attached via anchor bolts 6 to five locations in total: four locations almost directly above the car-side guide rail 7 and the counterweight-side guide rail 8, and one location directly above the counterweight 9. The guide rails 7 and 8 are then connected by latching the lifting machine 4 to the guide rails 7 and 8, and are sequentially connected at the bottom floor to integrate the entire height of the hoistway 10, and the top part is connected to the machine room 2.
The lowermost part is fixed to a shock absorber (not shown), and the lowermost guide rails 7 and 8 are fixed to the hoistway 10 by setting brackets (not shown) for the guide rails 7 and 8. Next, a car (not shown) and a counterweight 9 are assembled on the lowest floor, and the counterweight 9 is hoisted to the highest floor using a lifting machine 4, and a rope hanging operation is performed.

[Problem that the invention attempts to solve]

With conventional elevator installation equipment as mentioned above,
A large number of hanging metal fittings 5 are required for lifting the weight, and in addition, driving the anchor bolts 6 into the ceiling of the machine room 2 requires upward work on a stepladder, which is poor workability. It took a lot of time to install.

In addition, the lifting hook 1 for lifting the hoisting machine and control panel must be installed when concrete is poured for the ceiling of the machine room 2, and it is necessary to bring them along with the building construction process before the elevator construction begins. ,Also,
When lifting rails at other positions, there is a risk of a worker falling into the lifting hole 3 during setup change work of the lifting machine 4, which poses a safety problem. Furthermore, since the anchor bolt 6 is almost disposable, there is also a problem from an economic point of view.

This invention was devised to solve these problems, and the purpose is to provide an elevator installation device that can significantly shorten working time, is highly safe, and is economical.

[Means for solving problems]

The elevator installation device according to this invention presses and fixes the slide guide rail from below against the ceiling surface of the machine room using a telescopically adjustable support, and also attaches a trolley to the slide guide rail so that its position can be moved in the longitudinal direction. A type hoist is attached, and a lifting machine is attached to this trolley type hoist.

[Effect]

In this design, the lifting machine is attached to the slide guide rail pressed from below against the ceiling of the machine room via a trolley-type hanging device, so the lifting machine can be positioned freely along the slide guide rail. It becomes possible to move it. Therefore, it is possible to omit a plurality of hanging metal fittings and their anchor bolts, which were conventionally required, and movement in the right angle direction can be easily performed by releasing the pressure from the support.

〔Example〕

1 and 2 show an embodiment of this invention, and in the figures, the same reference numerals as in FIGS. 3 and 4 indicate the same or corresponding parts. Reference numeral 11 denotes a slide guide rail for lifting, which is fixed by being pressed from below against the ceiling surface of the machine room 2 by adjusting the expansion and contraction of supports 12, such as pipe supports formed of, for example, I-shaped beams and arranged at both ends in the longitudinal direction. ing. 1
3 and 13a are self-supporting seats attached to the lower end of each support 12, and the shape thereof is arbitrary so as to have a wide ground supporting point. 14 is a trolley-type hanging tool attached to the slide guide rail 11 so as to be freely movable in its longitudinal direction;
The lifting machine 4 is attached to this trolley type fitting 14. 15 and 15a are each support 1 above.
A height adjustment hole 16 provided in the height adjustment hole 2 is a pin inserted into the height adjustment hole 15, 15a, and FIG. 2 shows a pin inserted into the height adjustment hole 15a.

In the elevator installation device configured as described above, the trolley-type lifting device 14 is moved in the longitudinal direction of the slide guide rail 11, and the lifting device 4
Set it to the optimal position and perform the work. At this time, the trolley type hanging tool 14 is attached to the slide guide rail 11.
Since it can be moved freely along the road, it can be lifted in a location where there is little danger during work, and then moved to its normal position. Also, support 1
If the pressing force by 2 is released, the slide guide rail 11 can be moved freely and easily, so that it can be easily moved in the right angle direction. Moreover, even if there is a step between the self-supporting seats 13 and 13a of each support 12, the height adjustment holes 15 and 15a
By changing the insertion position of the pin 16,
be able to respond adequately.

In the above embodiment, an I-shaped beam is used as the slide guide rail 11, and the support 12 is
The case where a pipe support is used is shown, but
Any material may be used as long as it has the same functions as these.

[Effect of idea]

As explained above, this idea is to fix the slide guide rail by pressing it from below against the ceiling of the machine room using a support that can be expanded and contracted. Since a lifting device is attached to the trolley type lifting device, the lifting point can be moved easily and quickly, and there is no need to attach a hanging device to the ceiling at each lifting point. , it is possible to obtain an elevator installation device that is safe, economical, and can be used in most elevator machine rooms.
