Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a device for fixing an elevator guide rail to a hoistway wall.

[Conventional technology]

In an elevator, a car and a counterweight are connected by a main cable, and the counterweight is placed behind the car.

FIG. 3 shows a conventional elevator guide rail device disclosed in, for example, Japanese Utility Model Publication No. 55-28703.

In the figure, (1) In the hoistway of the fl elevator, the front wall (1a
).

It consists of a side wall (1b) and a rear wall (1c). (2)
is the entrance/exit provided in the front wall (1a), and (3) is the hoistway (
1), (4A) and (4B) are placed upright along the side wall (1b) and are placed facing each other across the basket (3), and guide the raising and lowering of the basket (3). rail, (5) I-! A fixture fixed to the back of the car rails (4A) and (4B).

(6) is a support that is fixed to the side wall (1b) and fixed to the fixture (5) to support the car rails (4A) and (4B); 9th cup
), (8A).

(8B) are erected along the rear wall (1c) and are placed facing each other with the counterweight (7) in between.
7) is a weight rail that guides the lifting and lowering, and (9) is a fixture fixed to the back of the weight rails (8A) and (8B).

The member is a support that is fixed to the rear wall (1c) and fixed to the fixture (9) to support the main 9 rails (8A) and (8B).

A conventional elevator guide rail device is constructed as described above, in which a support (5) is fixed to the side wall (1b) with foundation bolts, and a car rail (4) is attached to this via a fixing device (5).
A) and (4B) are supported. Similarly, the weight rails (8A) and (8B) are supported by the rear wall (1c) via the fixing device (9) and the supporting device α@.

[Problems that the invention helps solve]

In the conventional elevator guide rail device as described above, since the car rails (4A), (4B) and the weight rails (8A), (8B) are supported separately, their fixing devices (5) , Setting (9) requires centering and adjustment work for each one, and the installation work takes a lot of time. In addition, there are problems such as the large number of fixtures (5) and (91), which increases material and processing costs.

This invention was made to solve the above-mentioned problems, and it is possible to shorten the installation work time of the rail for the roof, and
It is an object of the present invention to provide a guide rail device for an elevator that can reduce the cost required for fixtures.

[Means for solving problems]

The guide rail device for an elevator according to the present invention has one of the car rails and one weight rail erected on the same side, and these are connected by a common fixture.

[Effect]

In this invention, one of the car rails and one weight rail are connected by a common fixture, so the relative position of one rail is naturally regulated.

In addition, the shared fixture shares the members necessary for fixing both rails.

〔Example〕

FIGS. 1 and 2 are views showing an embodiment of the present invention. FIG. 1 is a cross-sectional view of a hoistway, and FIG. 2 is a rear perspective view of a guide rail portion. (Ic), +2
+, (31, (4A), and (4B)) are the same as in the conventional device described above.

In the figure, (13) is placed on the side of the heel (3) and the side wall (1
b) The guide shoe 〇 is attached to the center of the side. A weight rail that is formed by a longitudinal member with a π-shaped cross section and engages with a guide shoe αj to guide the lifting and lowering of the counterweight HI3 (1cJ basket rail (4A) back surface and weight) αe is a shared fixture that connects the back surfaces of the car rails a4 to each other, and αe has an L-shaped cross section, is placed behind the car rail (4A), has a side surface fixed to the side wall (1b), and has a shared fixture on the top surface. A5 is a welded car side support, and +l is a weight side support that is also placed behind the weight rail α4 and welded to the common fixture α9.

In the elevator guide rail device configured as described above, the car rails (4A), (4B) and the weight rail # (13) are operated by a winch installed in the machine room directly above the hoistway (1). , are added one by one from the bottom of the hoistway (1) and each rail is placed over the entire height of the hoistway (1).First, at the bottom of the hoistway (1), the car rails (4B) are A fixture (5) is connected to the car rail (4A), and a common fixture (15) is connected to the car rail (4A) by a well-known rail gripping tool (not shown). I is simultaneously coupled in place by the holes drilled in the common fixture (15).Then, after the car rails (4A) and (4B) are centered by a centering jig (not shown) , side wall (
Fixtures (15, +51 are welded to the support αe, +6) fixed to 1b) with foundation bolts. Weight rail α
4 is coupled to the common fixture α9, so its relative position with the car rail (4A) is naturally regulated. Therefore, the common fixture a9 can support the main lever α in a predetermined position by simply welding it to the support αη.

By repeating the above steps upwards.

Car rail/L/(4A), (4B) and weight rail a knob.

Common fixtures (to), fixtures (5) and supports αυ, αη
, (6) to be securely attached to the side wall (1b).

In this way, by centering the car rail (4A) e, the center of the weight rail α4 comes out at the same time, so there is no need to center the weight rail I, and the installation work is simplified. installation costs are reduced.

In addition, in this embodiment, the car rail (4A) and the weight rail I are arranged close to each other, and the members for fixing each are shared by the common fixture (15), so the material cost and processing cost are reduced. be done.

〔Effect of the invention〕

As explained above, in this invention, the main rail of the elevator is erected on the same side as one of the car rails, and these are connected by a common fixture.

Installation workability can be improved by eliminating the need for centering work of the main rail. Further, there is an effect that the material cost and processing cost of the fixture can be reduced.
