摘要:
A device for attaching a code strip to a supporting structure of an elevator is in the form of a fitting tool capable of being guided along the supporting structure to play out an extended length of code strip material. The fitting tool has a guide shoe and a strip station mounted to the guide shoe for attaching the code strip to the supporting structure as the fitting tool is slid along the supporting structure, such as a guide rail, by a mechanic.

Equipment for determining a position of an elevator car movable along a guide flange of a guide rail in an elevator installation with a code carrier extending in a travel direction along a length of the guide rail in a groove includes a mount attached to the elevator car, a code reading sensor system attached to the mount, and a plurality of guide rollers rotatably attached to the mount and rolling on the guide flange to maintain the code reading sensor system at a predetermined spacing from the code carrier along two axes.

A method and a device for determining the state of a rail stretch utilize a receiver that is moved along the rail stretch to receive radio signals transmitted by at least three transmitters mounted in the elevator shaft. Spacing data is determined from the radio signals and is compared by an evaluating unit with reference data of the spacing to generate a result with respect to the state of the rail stretch. The positions of rail fastenings, connecting straps and shaft doors can be detected by additional sensors also moved along the rail stretch and are represented in a correction protocol to permit an efficient adjusting of the rail stretch.

A method for temporary protection of blank surfaces of a component against corrosion includes a first step wherein a corrosion protection foil is applied to a blank surface to be protected and a second step wherein a self-sealing, semi-solid protection layer is applied in order to at least partly cover the corrosion protection foil. At a later time at least a part of the blank surface can be exposed by pulling off the corrosion protection foil inclusive of the protection layer disposed thereon. The self-sealing protection layer forms a closed film and the corrosion protection foil and/or the protection layer comprise hydrophobically acting components in order to prevent moisture from penetrating to the blank surface to be protected.

An elevator system includes a lift cage, which is provided with a belt having markings disposed along the length thereof. A device for detecting at least the position, optionally, also the speed and the acceleration of the elevator cage, which is used to scan the markings, comprises a detector which is secured to the elevator cage and is displaced therewith. The detector is, preferably, arranged in such a manner that it detects the markings in one section of the belt which extend from the underloop of the carrier rollers on the elevator cage directly to a fixed point of the belt.

The invention relates to a lift system (10) comprising a lift cage (11), which is provided with belt-like traction/drive means (14) which comprise markings (12) disposed along the length thereof. A device for detecting at least the position, optionally, also the speed and the acceleration of the lift cage, which is used to scan the markings (12), comprises a detector (13) which is secured to the lift cage (11) and is displaced therewith. The detector is, preferably, arranged in such a manner that it detects the markings (12) in one section of the traction/drive means (14) which extend from the underloop of the carrier rollers (19) on the lift cage (1) directly to a fixed point (14.4) of the traction/drive means (14).
摘要:
Position transmitting equipment for ascertaining the position of a rail-guided elevator car includes a code carrier, which is arranged over the car travel path in fixed location on a guide rail with code marks of different permeability. A permanently precise reading of the coding is ensured by the fact that the code carrier is fixedly connected with a non-magnetic cover externally covering the code marks. The code carrier together with the outwardly facing non-magnetic cover are inserted into a receiving groove of the car guide rail, whereby a simple and reliable mounting is achieved and, in addition, temperature-dependent differences in expansion between the code carrier and the guide rail are avoided.
摘要:
An apparatus and a method for generating hoistway information from images of the surface patterns of a hoistway component such as a guide rail sensed by a CCD line camera. The image data are input into a first correlator which uses an incremental position of a new image and an absolute position of a preceding image to generate an estimated position. The estimated position is input into a second correlator and is used to locate the relevant database sector in which the image which was stored in the database during calibration is situated. The second correlator compares the new image with the stored image and determines from the position index of the stored image the absolute position of the elevator car which is transmitted to the elevator control.
