Description

Rail mounting device of elevator {RAIL FIXING DEVICE OF ELEVATOR}

The present invention relates to a rail mounting apparatus for an elevator for mounting a guide rail for guiding the lifting body of the elevator to an inner wall surface of the lifting path.

In a conventional elevator, in order to guide a car and a counterweight, some guide rail may be provided in a hoistway. Each guide rail is being fixed in the hoistway by the fixing bracket. Japanese Utility Model Application Laid-Open No. 4-56179 discloses a reinforcing member disposed in a hoistway separate from the fixing bracket to reinforce the fixing of the guide rail. The reinforcing material is fixed to the other inner wall surface perpendicular to one inner wall surface to which the fixing bracket is fixed. In addition, the reinforcing material is disposed to sag in the height direction with respect to the fixing bracket.

In addition, Japanese Utility Model Application Publication No. 55-11994 discloses a guide rail fixing bracket capable of adjusting the position of the guide rail in the horizontal direction. The guide rail fixing bracket has a wall side bracket fixed to the inner wall surface of the hoistway, and a rail side bracket mounted on the wall bracket and having an adjustable position with respect to the wall bracket. The rail-side bracket has a vertical portion disposed parallel to the inner wall surface of the hoistway, and a horizontal portion extending from the lower edge of the vertical portion to the inner wall surface side of the hoistway (back side of the vertical part). The horizontal portion is provided with a long hole through which a mounting bolt for mounting the rail side bracket to the wall side bracket passes. By adjusting the position with respect to the long hole of a mounting bolt, the position with respect to the wall side metal fitting of a rail side metal fitting is enabled.

However, in the conventional elevator disclosed in Japanese Utility Model Application Laid-Open No. 4-56179, since the reinforcing material is separate from the fixing bracket, the fixing bracket and the reinforcing material must be mounted one by one on the inner wall surface of the hoistway. I am tired of installation work in the inside.

In the conventional elevator disclosed in Japanese Utility Model Laid-Open No. 55-11994, since the horizontal portion of the rail side bracket is disposed on the back side of the vertical portion, when the rail side bracket is mounted on the wall side bracket with a mounting bolt, The inner wall surface and the vertical portion are obstructed and the product is held by the fastening of the mounting bolt.

This invention is made | formed in order to solve the above subjects, and an object of this invention is to obtain the rail mounting apparatus of the elevator which can reduce the goods which are required for the installation work in the hoistway of a guide rail.

The rail mounting apparatus of an elevator by this invention is an rail mounting apparatus of the elevator which mounts the guide rail for guiding the lifting body of an elevator with respect to the 1st inner wall surface and the 2nd inner wall surface which adjoin each other of a hoistway, A first wall fixing portion fixed to the first inner wall surface, a second wall fixing portion fixed to the second inner wall surface, a mounting portion to which the guide rail is mounted, a first wall fixing portion, A second wall fixing portion and a mounting portion are provided with a bracket member integral with each other.

A car (not shown) that is a lifting body is disposed between each car guide rail, and a counterweight 3 that is a lifting body is disposed between each counterweight guide rail 2. The car is guided to the car guide rail to elevate the inside of the hoistway 1, and the counterweight 3 is guided to the counterweight guide rail 2 to elevate the inside of the hoistway 1.

A part of the hoistway 1 is adjacent to the 1st inner wall surface 4 and the 1st inner wall surface 4 which the counterweight 3 opposes, and is perpendicular | vertical to the 1st inner wall surface 4 It is comprised by the pair of 2nd inner wall surface 5 which is phosphorus. The first inner wall surface 4 is parallel to a straight line connecting the counterweight guide rails 2 in the vertical projection surface of the hoistway 1. Moreover, in the vertical projection surface of the hoistway 1, the counterweight 3 and the pair of counterweight guide rails 2 are arrange | positioned between each 2nd inner wall surface 5.

Each counterweight guide rail 2 has a rail body 7 including a back (back) 6 facing the second inner wall surface 5 and a counterweight 3 from the rail body 7. It has a guide portion 8 which protrudes and guides the counterweight 3. Moreover, each counterweight guide rail 2 is attached to the 1st and 2nd inner wall surfaces 4 and 5 via the rail mounting apparatus (henceforth a "rail mounting apparatus") 9 of an elevator. have.

FIG. 2 is a perspective view illustrating the rail mounting device 9 of the elevator of FIG. 1. In the figure, the rail mounting apparatus 9 has the bracket body 10 fixed to the 1st and 2nd inner wall surfaces 4 and 5, and to which the counterweight guide rail 2 is mounted.

The bracket body 10 is the horizontal part (base part) 11 arrange | positioned horizontally between the counterweight guide rail 2 and the 2nd inner wall surface 5, and the 1st of the horizontal part 11, The first wall fixing portion 12 and the horizontal portion 11 which extend along the first inner wall surface 4 from the end on the inner wall surface 4 side and are fixed to the first inner wall surface 4. A second wall fixing portion 13 extending along the second inner wall surface 5 from an end portion of the second inner wall surface 5 side and fixed to the second inner wall surface 5; It extends upward along the back surface 6 from the end of the counterweight guide rail 2 side of 12), and has the mounting part 14 to which the counterweight guide rail 2 is mounted.

Moreover, the bracket body 10 is produced by bending one metal plate. That is, the horizontal part 11, the 1st wall fixing part 12, the 2nd wall fixing part 13, and the mounting part 14 are comprised integrally by the same member.

An elongated hole 15 extending in the vertical direction is provided in the first wall fixing part 12, and an elongated hole 16 extending in the horizontal direction is provided in the second wall fixing part 13. Moreover, the pair of bolt through-holes 17 arrange | positioned at the space | interval wider than the width | variety of the rail main body 7 is provided in the attaching part 14. As shown in FIG.

The long hole 15 is passed through an anchor bolt (not shown) for fixing the first wall fixing portion 12 to the first inner wall surface 4. In addition, an anchor bolt (not shown) for fixing the second wall fixing portion 13 to the second inner wall surface 5 passes through the long hole 16. Moreover, the bolt (not shown) for fixing the pair of rail clips (not shown) which abuts on both sides of the rail main body 7 to the mounting part 14 is passed through each bolt passage hole 17. As shown in FIG. . The counterweight guide rail 2 is attached to the mounting part 14 by fixing to each mounting part 14 of each rail clip.

Next, the mounting procedure of the counterweight guide rail 2 in the hoistway 1 is demonstrated.

First, the several bracket body 10 is arrange | positioned in the hoistway 1 at intervals from each other in the height direction, and each 1st wall fixing part 12 is carried out to the 1st inner wall surface 4, and each 2nd Wall fixing portions 13 are fixed to the second inner wall surface 5 by anchor bolts, respectively.

Thereafter, the back surface 6 of the counterweight guide rail 2 is brought into contact with each mounting portion 14, and the counterweight guide rail 2 is attached to the mounting portion 14 by a rail clip. In this way, each counterweight guide rail 2 is provided in the hoistway 1.
