Description

DETAILED DESCRIPTION OF THE INVENTION The present invention comprises centering means for aligning and guiding a connecting rail towards an already installed guide rail.
In particular, it relates to equipment that connects elevator guide rails. This also applies to the installation of elevators, where pre-fabricated free-standing shaft modules are transported to the construction site with all individual parts fully installed, stacked and assembled into the elevator shaft using the recent Units 1. In connection with construction methods, particular attention must be paid to butt connections between guide rails. A good butt connection device with centering means facilitates the assembly of elevator shafts consisting of several shaft modules and helps save extensive assembly time at the construction site.

In the case of the device for connecting guide rails known from East German patent no. A tongue-shaped portion that fits into the groove is cut into the end face of the flange and web at the end. In addition, a seam plate tapered on all sides is welded to the flange of the lower guide rail end, and this seam plate fits into a bag-shaped connecting member welded to the flange of the upper guide rail end. do. Placed on the lower rail part! The joint plate, which is sloped on all sides, acts as a guide for the end face troughs and tongues, which are machined so that they fit together without any gaps, when connecting the two rail sections. The connecting member welded to the guide rail part covers the joint plate and is forcibly guided forward, backward, left and right, leading to proper alignment. A locking element driven into a keyway cut into the seam plate and the connecting member fixes both guide rail sections in their final working position. A disadvantage of the guide rail connection device described above is that both the seam plate and the connecting member are welded to the flange of the guide rail. Welding can generate thermal stress and tension, and these forces adversely affect the operating performance of the elevator cage. Also,
The keyways provided in the lock licks of both guide rail ends, at least the keyways on the connecting member, must be formed before the connecting member is welded to the guide rail flange. Therefore, it is necessary that the welded part does not interfere in any way with the functions of the grooves and tongues formed by cutting, and the key grooves formed by cutting. SUMMARY OF THE INVENTION The present invention aims to provide a device for connecting guide rails, in which both rail ends are automatically and exactly aligned during assembly, and there is no need to weld connecting elements to the guide rails. Suppose that This object is achieved by the invention whose features are specified in claim 1. The advantage obtained by the invention is essentially that the bolted seam plate with the necessary guiding means can be manufactured from commercially available flat sections or also from bent sheet metal pieces, in which case Mounting holes for bolting can be made at the factory in both the guide rail section and the joint plate section according to the gauge. When assembling the shaft module into the elevator shaft, the seam plate for the two guide rails facing each other, bolted to the butt connection of the lower rail, serves as a guiding means for the lower end of the upper guide rail. As a result, the support plate with the inclined surface and the laterally bent guide flange of the U-shaped guide plate are
When lowering the shaft module for assembly, accurately center it in the front, rear, left, and right directions. The final centering of the guide rail is further facilitated by observing the grooves and chamfered edges arranged on the end faces. It is also an advantage of the invention that the guide rail does not suffer from thermal stresses and tensions due to welding.

The present invention will be described in detail below based on embodiments shown in the accompanying drawings. In FIGS. 1 to 5, the L end of the lower guide rail is indicated by the reference numeral 1. At least on the end face of the web 1.2 of the lower guide rail 1 there are provided arms 1, 1 which receive tongues 2.1 projecting from the upper guide rail 2. A groove 1.1 and a tongue 2.1 are provided on each longitudinal side,
It has chamfered edges 1, 5, 2, and 5. The flange 1.3 of the guide rail 1 has, for example, four mounting holes 1,
4 are formed, and the holes of the support plate 3 and the guide plate 4 coincide with these holes 1.4. Support play 1-
3 consists of a flat section and is provided with, for example, eight mounting holes and has at its upper end an inclined surface 3.1 which serves as a guide for the connecting guide rail 2. The guide plate 4, which correspondingly also has eight mounting holes, consists of a U-shaped bent sheet metal plate and has two flanges 4.
, 1 and web 4.3. The flange 4.1 of the guide plate 4 laterally wraps around the support plate 3 and the flanges 1, 3 of the guide rails 1, 2. At the upper end of the guide plate 4, the two flanges 4.1 have webs 4,
guide fins 4, 4 with inclined surfaces 4, 2 separated from each other by a certain length and bent slightly outwards to serve as lateral centering means during installation of the connecting guide rails 2; is constructed on both sides. The upper end of the guide rail l and the lower end of the guide rail 2 are connected to each other via a support plate 3 and a guide plate 4, with bolts 5, slope washers 7,
They are pressed against each other and fixedly connected to each other by means of the fixing washer 8 and the nut -6.

It functions to compensate for the slope of 4. Guide plate 4, 1
The left-hand and right-hand inclined surfaces 4.2, 14, 2 in the figure 4 serve as lateral centering means during the installation of the connecting upper guide rail 2.

The lower end of the connecting upper guide rail 2 is pressed against the upper end of the lower guide rail 1, and is immovably connected to the upper end by a bolt 5, a fixing washer 8, and a nut 6. The above-mentioned guide rail connection device is connected to the guide rail 1 integrated into the shaft module during factory installation.
It is installed at the upper end of. Normally, the height of the Jaft module itself approximately corresponds to the height of the floor at that time. At each cage guide rail 1 facing the other cage guide rails, a support plate 3 is bored according to the gauge.
and the guide plate 4 shown in FIGS. 1 to 3 both cover the flanges 1 and 3 of the guide rail 1, and the four bolts 5, slope washers 7, fixing washers 8, and nuts as set in the above example. 6, or according to FIGS. 6 to 8, the support plate 3 is connected to the left and right hand guide plates 4 and 14 by means of four predetermined bolts 1-5, fixing washers 8 and nuts 10. Bol l is combined. In this case, the inclined surfaces 3, 1 and the lateral guide fins 4.4, 14, 4
are arranged at the protruding free ends of the support plate 3 and the guide plates 4, 14, respectively. In the above state, the first shaft module is carried into the building and fixed, and then another shaft module is installed on the first shaft module from above. The self-centering ends of the support plate 3 and the guide plates 4, 14 center the upper shaft module when it is lowered, and this centering means that the lower end of the connecting upper guide rail 2... on the one hand by the lateral guide fins 4.4, 14.4, and on the other hand by the sloped surface 3.1 of the support grate 3 supporting the two mutually opposite guide rails 1 and 2.
