FIGS. 2 and 3 are a front view and an enlarged view of a guide rail connecting portion of a conventional elevator guide rail centering device disclosed in Japanese Utility Model Application Publication No. 60-151875. In FIG. 2, reference numerals 1 and 1 indicate elevator guide rails, and these guide rails 1 and 1, each having a standard length of 5 m, are usually connected together. 1a
is a concave portion provided at the lower end of the upper guide rail 1, and 1b is a convex portion provided at the upper end of the lower guide rail 1 and engaged with the concave portion 1a. 2 is above;
It is arranged on the back side of the connection part of the lower guide rails 1, 1,
A batten 4 is a frame body of a centering device, which tightens and connects the guide rails 1, 1 with bolts 3 inserted through the flanges of these guide rails 1, 1.
The frame body 4 is formed into a substantially U-shape from the front, and two upper and lower jack bolts 4a are screwed into the vertical center of the frame body 4, and the tips of the upper and lower protruding parts of the frame body 4 are screw-fitted. are each provided with a grip portion 4b. In order to connect the guide rails 1, 1 using the centering device configured as described above, the bolts 3 should be properly tightened and the upper and lower guide rails 1, 1 should be temporarily tightened. Upper and lower gripping parts 4b provided on the frame 4 of the centering tool 9 are arranged above and below 2,
These gripping parts 4b are attached to the upper and lower guide rails 1, 1.
Engage with the flanges on one side from the outside, bring the tips of the two jack bolts 4a into contact with the flanges at the other end of the upper and lower guide rails 1, 1 from the outside, and tighten the jack bolts 4a. Then, as shown in Fig. 3, the bending angle θ of the connecting part caused by the gap G between the concave part 1a and the convex part 1b of the upper and lower guide rails 1 and 1 is corrected, and then the bolt 3 is fixed. It is tightened and centered so that the upper and lower guide rails 1, 1 are in a vertical straight line.

The conventional elevator guide rail centering device is constructed as described above, so if the jack bolts 4a are over-tightened, the upper and lower guide rails 1, 1 will bend in the opposite direction, and will come out from the opposite side. It is necessary to perform centering again using the jack bolts, and it is also necessary to control the tightening torque of the bolts 3 that tighten the guide rails 1, 1 and the battens 2. If the tightening torque is too large, the upper and lower guide rails There was a problem that it was difficult to correct the curvature of 1,1. This idea was made in order to solve the above-mentioned problems.A centering jig is removably attached to the connecting part of the upper and lower guide rails, making it possible to accurately correct the bending of the guide rails. The object of the present invention is to obtain an efficient and inexpensive centering device for an elevator guide rail.

An embodiment of this invention will be described below with reference to FIG. In Fig. 1, the same reference numerals as in Figs. 2 and 3 indicate corresponding parts, 5 is a shank vise, and 6 is a centering tool 9.
A pair of left and right stretching members. The shaft vise 5 has a C-shaped (or U-shaped) frame 5a with a threaded rod 5b screwed into one end of the opening and the other end opposite to the other end, and a tightening metal fitting is attached to the tip of the threaded rod 5b. 5c is fitted to the threaded rod 5b such that it can rotate relative to the threaded rod 5b while restricting movement in the axial direction, and a handle 5d is provided at the distal end of the threaded rod 5b. The pair of left and right stretching members 6 are composed of rectilinear square metal rods, and one end of a connecting fitting 7 is fixed to the upper and lower end surfaces of one of the stretching members 6, respectively. Elongated holes 7a extending parallel to the longitudinal direction of the stretching member 6 are formed at the ends thereof, and guide pins 8 are formed in these elongated holes 7a to protrude from the upper and lower end surfaces of the other stretch member 6.
are slidably engaged with each other, and the centering jig 9
is configured. Note that these members are arranged so that the longitudinal direction of the stretching member 6 and the longitudinal direction of the connecting fitting 7 are perpendicular to each other. Furthermore, one end of the frame 5a of the shank vise 5 is fixed to the outer surface of one of the stretching members 6, and the tightening fitting 5c of the shank vise 5 is fixed to the outer surface of the other stretching member 6, facing this fixed part. The frame 5a is fixedly placed in front of the centering tool 9 so as to straddle substantially the center of the left and right stretching members 6 in the longitudinal direction. Next, the operation of the guide rail centering device according to this embodiment will be explained. A batten 2 is provided on the back side of the joint between the upper guide rail 1 and the lower guide rail 1, and the batten 2 is arranged between the upper and lower guide rails 1 and the batten 2.
are connected by temporarily tightening them with bolts 3, and when a certain bending angle occurs in the connection part, apply the upper and lower connection fittings 7 of the centering jig 9 to the face surfaces 1c of the upper and lower guide rails 1, respectively. and rotate the threaded rod 5b of the shaft vise 5 with the handle 5d, and
By moving the right stretch member 6 in parallel so that the distance between them becomes narrower and squeezing it from the outside toward the inside so that it comes into surface contact with the upper and lower guide rails 1, the upper and lower guide rails 1 can be stretched. There is no bending angle, and these guide rails 1 become vertically straight. Furthermore, with the lower guide rail 1 tightened, the bolt 3 is strongly tightened to fasten and fix the upper and lower guide rails 1 via the battens 2. After completing the centering of the upper and lower guide rails 1 in this way, rotate the threaded rod 5b in the opposite direction to open the gap between the left and right stretching members 6, and remove the centering device of this embodiment. . Thereafter, repeat the same procedure to center all the connecting parts of the guide rail. In the above embodiment, the mounting bracket attached to one end of the frame of the shank vise and the threaded rod was fixed to the outer surface of the stretching member of the centering jig, but this invention allows the shank vise and the stretching member to be attached and detached. It may be possible.

As explained above, according to this invention, the left,
It consists of a centering jig that connects the right pair of stretching members so that they can move in parallel in the width (left and right) direction of the guide rail using a connecting fitting, and a shank vise that tightens the stretching members from the outside to the inside. ,
By pinching the outer surfaces of the connecting parts of the upper and lower guide rails with the left and right stretching members, rotating the threaded rod of the above-mentioned shaft vise, and pinching the upper and lower guide rails with the stretching members, the upper and lower guide rails can be separated. Since the connecting portion can be made into a vertical straight line with no bending angle, the bending of the upper and lower guide rails can be corrected with high precision and efficiency, and the device can be made at a lower cost.
