Abstract

PURPOSE:To facilitate the installation of a guide rail within a short time by forming a plurality of folded parts in one of a plurality of lining pieces and supporting a part of the folded part with the side edge part of the guide rail and the other part with a lining piece placed at the side of a frame. CONSTITUTION:One of lining pieces 6 and 16 is bent at one side and the other side of a groove 16B in the opposite directions to form folded parts 16C and 16D. The folded parts 16C and 16D are held at the down side with the lower edge part 4A of a guide rail 4 and the other lining piece 6, respectively. As a result, the need for spot welding of the lining pieces is eliminated so that the transportation of welding machines and the provision of power supply becomes unnecessary. When the lining piece 16 has the suitable thickness less than 1mm, after the entire lining pieces 6 and 16 are tightened, a personnel can fold the lining piece 6 by the hand. Thus the installation of the guide rails 3 and 4 can be executed easily within a short time.

Adjust the positions of the rails 3 and 4 in the direction to make the rail spacing appropriate. Then frame 2. ? l? ) The upper and lower edges 3A of the rails 3 and 4 on the flanges 2F and 2G of the auxiliary frame 2C. 4A is tightened and fixed by a bolt 5 and a nut 7 via a clamp 6.

[Problem to be solved by the invention]

A conventional guide rail mounting device for a passenger conveyor is constructed as described above, and a clamp is inserted between the frame and the guide rail mounting device from the front and rear directions in order to adjust the position of the guide rail in the width direction of the passenger conveyor. Since the nut is tightened on the tip of the bolt that passes through the bolt horizontally, there are the following problems. That is, it is difficult to control the tightening torque of the bolt at a constant level, and the clamp may fall off due to insufficient tightening torque. In addition, when the rollers installed on the pallet I/shaft run on the transfer surface of the guide rail, or when passengers on the pallet walk, vibrations are transmitted to the tightening part of the bolts, causing the pincers to fall off. Sometimes. In order to weld the clamp and the guide rail together in order to prevent them from falling off, it is necessary to transport welding equipment, secure a welding power source, etc., and installation is time-consuming. The purpose of this invention is to solve the above-mentioned problems and provide a guide rail mounting device for a passenger conveyor that can easily prevent the clamp from falling off without welding the clamp and the guide rail. It is said that

[Means to solve the problem]

The present invention provides a guide rail attachment device for a passenger conveyor as described above, in which one of the plurality of clips is provided with a plurality of bent portions, and some of the bent portions are supported on the side edges of the guide rail. At the same time, it is supported by a clip located closer to the frame than the clip provided with the other bent portion.

[For production]

The guide rail mounting device for a passenger conveyor according to the present invention is provided by simply making one of the plurality of clamps larger than the other clamps and bending a part of the clamp and the other part in opposite directions. This prevents the clip from falling off. In other words, because a part of the bent part of one clamp is supported by the side edge of the guide rail, the clamp with the bent part will be prevented from loosening the bolt or vibrating the clamp. It doesn't fall off either. In addition, for the remaining clamps, the other part of the folded part of the clamp with the bent part was supported by the clamp located on the frame side, so these clamps could not be attached to the clamp with the bent part. By integrating the plurality of clamps that are supported and located between the side edges of the frame and the guide rail, even clamps that do not have a bent part will not fall off due to bolt loosening or vibration.

【Example】

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. In FIGS. 1 and 2, the same reference numerals as in FIGS. 4 to 6 indicate corresponding parts, and 16 is a clip for providing a bent portion. The clip 16 is 1 m thinner than the other clips 6.
It is made of a thin plate of n+ or less and has a larger outer shape than the other clamps 6. In addition, as shown in FIG. 3, the clip 16 has a notch 16A extending horizontally in the front-rear direction and opening at one end of the front and back, and a notch 16A extending horizontally in the vertical direction and opening at one of the upper and lower edges. A groove 16B located at the center in the front-rear direction is formed. The clip 16 is overlapped with a plurality of other clips 6, and is connected to the lowermost flange 2F of the frame 2 and the lower edge 4A of the return guide rail 4, as shown in FIGS. During this time, a square root bolt 5 is inserted so as to be in contact with this side edge 4A, and is pushed through from the outside of the flange 2F into the square hole of this flange 2F, the notches 6A and 16A of the clamps 6 and 16, and the lower edge 4A. By tightening the nut 7 on the tip portion protruding inward from the lower edge 4A, the nut 7 is tightened together with the other clamps 6. The pincer 16 has a side with the groove 16B disposed downward, and a bent portion 16C formed by bending one side of the groove 16B at right angles to the lower edge 48 of the guide rail 4.
is engaged and supported from below by the lower edge 4A, and the groove 16B
A bent portion 16D, the other side of which is bent at right angles in the direction of the flange 2F of the frame 2, is engaged and supported from below by all the clips 6 that do not have bent portions. The configuration of this embodiment other than those described above and the installation operation of the guide rails 3, 4 are the same as those shown in FIGS. 4 to 6. The guide rail mounting device according to this embodiment includes clips 6,
16 is bent in opposite directions at one side and the other side of the groove 16B to form bent portions 16C and 16D,
Since the bent portion 16C is supported by the lower edge 4A of the guide rail 4, and the bent portion 16D is supported by the other clamp 6 from below, it is necessary to boil and weld the clamps. There is no need to transport welding equipment or secure a power source. In addition, since the clip 16 is made to have an appropriate thickness of 1 mm or less,
After tightening all the clamps 6, 16, the operator can bend the clamps 6 by hand. With these, the guide rails 3 and 4 can be easily installed in a short time. In addition, in the above embodiment, the bottom of the return guide rail 4 (m
A clip 16 with bent portions 16C and 16D was used only between the lltS4A and the flange 2F of the frame 2. However, this invention can be applied to guide rails using clips such as the lower edge of the outward guide rail. Flange between side edge and frame This fastening part can be applied to any fastening part, and the number of bent parts of the clamp may be three or more. It may be arranged between other clamps, and substantially the same effect as that of the above embodiment can be obtained also by these. [Effects of the Invention] As explained above, according to the present invention, a plurality of pincers are interposed between the frame fixed to the truss and the side edge protruding from the opening of the guide rail and are fastened together. One of the metal pieces has multiple bent parts, and some of the bent parts are supported by the side edges of the guide rail, and other bent parts are supported by the clips located on the frame side. , just by bending one part of the clip and the other part in opposite directions,
It is possible to easily prevent the clamps from falling off due to bolt loosening or vibration without welding the clamps, and the guide rail can be easily installed in a short time.
