Description

[Detailed description of the invention] How to install guide rails The present invention relates to a method for installing guide rails. In particular, not only that However, the improved spring clip type installation for elevator guide rails is easier. Regarding the law.

High-speed elevators used in high-rise buildings must be properly installed with guide rails. Setting strict criteria regarding the design of 1. There is τ. For driving comfort and safety , install the guide rails in accurate and reliable horizontal alignment, and prevent the elevator from wobbling during operation. It is important to prevent knocking or rattling. Also, guide L・-ru is a guide It must be able to slide to compensate for the gap between the rail and the literati of the elevator. . This misalignment may occur as a result of building subsidence or due to guide rails or bridges. This may be the result of thermal expansion or contraction of the metal base of the ruding.

The possibility of this misalignment is due to the inability to use a strong guide rail clearance knob. means. These strong guide rail clips typically attach the rail to a supporting structure. Forged steel that clamps firmly against structures and provides high shear strength and safety. It is a rule. Instead, some form of sliding clip must be used. In the past, there were three main alternatives.

One is the use of a U-shaped spring clip made from spring steel. One of U The arm is clamped tightly against the support bracket while the other arm It is pushed onto the rail and the clip is fixed to the support bracket. Therefore, the clamping force is generated by the deflection of the clip. .

The clamping force depends on the spring properties and the variability of this force is due to the It will depend on the accuracy or inaccuracy of both manufactures. caused by deflection Stress levels are high, which means that the clip is hardened and/or baked after it is formed. Reversion may be necessary. Spring clips are therefore expensive, but they are generally has appropriate strength, elasticity, and sliding properties.1. Moreover, it is easy to use and easy to use. It has good properties regarding attachment.

Another one is the use of compressed steel clips.

These require only one piece stamped from a relatively inexpensive metal, mild steel plate. It is inexpensive in that respect. 1.7 or 1. The bolts are tightened so The stress of deflection of the lip L exceeds the yield stress of the material I7 and is therefore approximately constant will form a plastic hinge that generates a clamping force. But the clip has limited recovery potential and therefore after the clip is fully tightened Any movement of the wheel will cause the clip to have additional permanent set and loosen. make it possible.

Yet another is the use of restraining clips. These restrain the rails in the horizontal plane Although the rails are designed to support and move freely in vertical planes, It is possible. Is there theoretically no clamping force between the rail and the clip? , ensuring that the rail is restrained but not actually clamped yet. Relying on the skill and care of the installation personnel, this theoretical maximum is achieved. is difficult.

This type of clip also provides effective correction for guide rail manufacturing errors. has no power. Because this was designed to generate a clamping force This is because it is not a thing. Additionally, if there is a continued relative relationship between the rail and the clip If there is any movement, remove the brinelling of the parts. may become unrestrained and therefore the clip may need to be adjusted in service. could be.

The object of the invention is to provide a guide rail which solves or reduces the disadvantages of the conventional fixation methods mentioned above. The installation for the tool is to provide a method.

The present invention provides support bracket means affixable to an elevator access wall and said support bracket means. one arm of each clip adapted to be attached to the face of the bracket means; The clip rests against the support bracket means to prevent lateral movement of the clip. the guide rail, the other arm being pushed hard towards the support bracket means a pair of U-shaped spring clips that push onto the lateral flanges of the , for attaching the Ri1rusop to the support bracket means, and for attaching the Ri1rusob to the support bracket means. pass through the holes in both arms and tighten the arms of the chestnut knob adjacent to the support bracket means. In normal use of the clip and the shoulder part, it is impossible to ride on the other arm while pushing. If the rail flange is not held by this arm but the support bracket is in hand If you receive a force in an outward direction against the step, ride while pushing on the other arm. each row of shoulder screw means having a head spaced from the shoulder by a distance such as A method is provided for installing an elevator guide rail comprising:

The pair of shoulder screw means includes a pair of shoulder bolts for use with each row of nuts. and said nuts are spaced apart at predetermined intervals by spacer means. It is placed as follows.

In such a case, the support bracket means is such that said shoulder screw means is secured therethrough. can have a laterally elongated hole that can be The roll can be vertically aligned in place by means of both shoulder screws; Each shoulder screw means is then tightened to hold the rail in place.

Preferably, each clip has a bearing zone with relatively low frictional resistance. Preferably, said zone is adapted to ride on the flange.

The zone may be a button or stud of material such as stainless steel. Also good.

Additionally or alternatively, a bearing area having relatively low frictional resistance may and the support bracket means.

The support bracket means may have first and second substantially perpendicularly angled brackets. The first bracket may be fixed to a wall of the elevator access, and the first bracket may be fixed to a wall of the elevator access. the bracket of 2 provides a surface to which the rail can be attached; The first and second brackets are connected to the surface of the second bracket and the elevator access wall. and are connected in such a way that the distance between them is adjustable.

Embodiments of the invention will be described in more detail by way of example and in conjunction with the accompanying drawings. Figure 1 is a perspective view of a guide rail installation embodying the present invention. , FIG. 2 is a plan view of guide rail attachment.

The elevator guide rail 9 is such that one arm thereof contains the guide rail itself and the other two generally T-shaped forming a pair of flanges attached to the feet of the guide rail. It has a cross section. As mentioned above, it is the extension between the guide rail and the building. vertically to adjust the elevation differential or to adjust the settlement of the building. You must be able to move freely. It is also aligned horizontally and the entire guide rail is complete. managed to be completely vertical or as close to it as possible, so that the elevator must be ensured that they do not sway or become misaligned during operation.

The support bracket for the guide rail consists of a pair of connected substantially right angle brackets. It is equipped with rackets 3 and 13. The first bracket 13 has a bolt passing through the hole 12. or the like, to the wall of the elevator shaft. second bracket The bolt 3 is attached to the first bracket 13 by a bolt 14 used together with a nut 16. The pair of nuts 16 can be attached to the spacer plate 15 to make it easier. connection. The vertically disposed surface 3a of the second bracket 3 is It can be located at a predetermined distance from the wall of the elevator shaft. This side 3 a is adapted to receive the guide rail 9.

The guide rail is held by a pair of spring clips and each shoulder screw 2 It is held on the surface 3a of the bracket 3.

Each spring clip is U-shaped and contains hardened and tempered steel. is preferred. The U-type includes a first arm 1a and a second arm 1b. The arm 1b of 2 is intended to contact the vertical surface 3a of the support bracket. .

Each arm of the U is provided with a hole for receiving a shoulder screw 2.

Each shoulder screw 2 has a hexagonal head and from there vertically (in the direction of the screw thread) and spaced shoulders. It has a shoulder that contacts the inner arm 1b of the U. On the other hand, there is still a distance of 0.5ma between the head of the screw and the outer arm 1a of the U-clip. They are spaced by such distances as to allow distances between + and 1.5 ■.

Each pair of shoulder screws 2 is attached to the spacer plate 8 on the far side of the surface 3a. The nut 4 is engaged.

The U-shaped spring clip holds the flange of the rail against surface 3a in a spring clip style. work to maintain it. Shoulder screw 2 can hold the flange of rail 9 is almost tightened and the rail still remains in the transverse slot lO of surface 3a. can be moved sideways in pairs while holding the handle 9. Therefore the guide rail can be aligned vertically. Then tighten the screw further. The rails are held firmly in this predetermined position.

As you can see here, the pushing force on the rail is not excessively large, therefore The rail can slide vertically within the clip. To increase this slipperiness The clip is made of stainless steel, which has a lower coefficient of friction than the material of the clip itself. button 6 is arranged. It is also resistant to corrosion and hence friction Less likely to damage its surface which may increase the coefficient. Similarly with rail 9 A slide plate 7 is arranged between the rail 9 and the surface 3a. allows for easy movement.

To mount the guide rail, the support bracket is mounted on the wall of the elevator hole and The guide rail or a portion of the guide rail is then placed approximately in place. Chestnut The tops 1 are then utilized, but the shoulder screws 2 are fully inserted into their nuts 4. It cannot be tightened. There the guide rails 9 are aligned vertically and less One of the nuts 2 is tightened to hold the rail in place. Other clicks Due to the effect of the spacer plate 8, the screw moves as the first mentioned screw moves. Will. This second screw can be tightened later.

Under normal circumstances the clip 1 allows vertical movement of the guide rail 9 but the plane 3 Acts as a spring clip to prevent movement of the guide rail flange away from a . If the force on guide rail 9 is applied around the edge of one end of the flange of the guide rail If it seems to cause some rotational movement, the clip subjected to that force will This movement continues until the outer surface 1a of the clip contacts the head of the screw 2. would make it possible. At this point, the load is removed from the flexure of the U-clip. is transferred to the location of the clip where it contacts the head of screw 2. Therefore, The spring properties of the cup change significantly, perhaps even being strengthened by a factor of three. However, Unless the forces on the guide rail become exceptionally excessive, the guide rail should not be removed. It will continue to be held within the main clip 1.

The mounting method embodying the invention therefore allows vertical movement of the guide rail 9. while the flange of the rail has a small It will still prevent lateral movement that would cause small spacing. with both shoulders The screws 2 are attached to the spacer plate 8 so that both clips and therefore The final adjustment of the rails 9 held by them can be easily achieved. There will be. The expected force on the guide rail 9 is for a normal spring clip. It is adjusted in the same way as the previous method, but unusual distortion of the guide rail or spring clipping This is prevented by the effect of the head of screw 2 contacting the outer arm 1a of the cup. There is a certain degree of safety in that
