Description

DETAILED DESCRIPTION OF THE INVENTION The present invention has centering means for aligning and guiding the connecting rails towards the already installed guide rails.
In particular, it relates to a device for connecting elevator guide rails.

It is also applied to the installation of elevators, in which case a self-supporting shaft module produced in advance from the factory is transported to the construction site with all individual members completely attached, and is stacked and assembled into an elevator shaft. In the context of, particular attention must be paid to the butt connection of the guide rails. A good butt joint with centering means facilitates the assembly of elevator shafts consisting of several shaft modules, helping to save valuable assembly time at the construction site.

In the case of the device for connecting the guide rails, which is known from East German Patent No. 92 525, a groove is cut and formed in the flange of the lower guide end and the end face of the web at the butt joint between the guide rails and the upper guide end A tongue is cut into the end of the flange and the web of the section to fit the groove. In addition, the flange at the end of the lower guide rail is welded with a seam plate that is tapered on all sides, and this seam plate is fitted into a bag-shaped connecting member welded to the flange at the end of the upper guide rail. To do.
The all-sided sloping seam plate, located on the lower rail part, serves as a leading part for the groove and tongue of the end face, which are cut and formed so as to fit tightly when connecting both rail parts. At that time, the connecting member welded to the upper guide rail portion covers the joint plate, and is forcibly guided in the front, rear, left and right directions to be guided to the proper alignment position. Locking elements, which are driven into keyways engraved in the seam plate and the connecting member, secure the two guide rail parts in their final working position.

A drawback of the guide rail connecting device described above is that both the seam plate and the connecting member are welded to the flange of the guide rail. Welding can cause thermal stresses and tensions, which adversely affect the running performance of the elevator car. Also, the keyway provided for locking both guide rail ends, at least the keyway towards the connecting member, must be formed before the connecting member is welded to the flange of the guide rail. Therefore, it is necessary that the weld does not interfere with any function of the machined groove and tongue and the machined keyway.

The present invention is a device for connecting guide rails, wherein both rail ends are automatically and accurately aligned during assembly,
Another object is to provide a device which does not require welding of the connecting element to the guide rail.

This object is achieved by the invention, the features of which are set forth in the first claim.

The advantage obtained according to the invention is essentially that a bolted seam plate, having the necessary guiding means, can be manufactured by means of commercially available flats, or also by bent sheet metal strips. The mounting holes for the fastening can be made in the guide rail part and the seam plate part at the factory according to the gauge. When assembling the shaft module to the elevator shaft, the seam plates for the two guide rails facing each other, bolted to the butt joints of the lower rail, serve as guide means for the lower end of the upper guide rail. The supporting plate with the inclined surface and the laterally bent guide flange of the U-shaped edging guide plate thus move the upper shaft module forward, backward, leftward and rightward when lowered for assembly. Accurately center. The final centering of the guide rail is further facilitated by having grooves arranged on the end faces and chamfered tongues. It is also an advantage of the present invention that the guide rails do not suffer the thermal stress and tension due to welding.
