摘要： PROBLEM TO BE SOLVED: To easily determine a roller replacing time during operation without using any measuring devices by partially providing a projecting or a recessed part in the circumferential direction of a roller side face in a device where a pulley rotated in synchronization with an elevator car is rotated by pressing a roller integrally provided with a position detector. SOLUTION: An elevator car is raised by the rotation of a motor directly connected to a hoist sheave. A lever provided in a part of the car is connected to a speed governor pulley 8 provided in a machine room in the upper part of a vertical path and a governor rope 7 wound on a tension pulley in the bottom part of the vertical path. A roller 12 for driving a position detector is contacted with the roller rolling surface 11 of this governor pulley 8 and the number of pulses is produced in proportion to the moving amount of the car from the position detector. In this case, a recessed groove 12A-1 is provided in an L position from an outer periphery (wear limit and replacing reference value of the roller 12) in the side face of the roller 12, and by periodically confirming this mark by eyes, its wear is determined and replacing work is carried out.

摘要： PURPOSE: To reduce noise generated at the time of high speed travelling and to improve riding comfortability by making a shape of a position detection device in a streamline shape against the forwarding direction and installing an attachment in such a shape to a conventional device so as to make it correspond with it. CONSTITUTION: A shape of upper and lower surfaces of a position detection device is made in a streamline shape to reduce air resistance at the time of elevation of a cage concerning the position detection device to put on and off a contact point by inserting a shielding plate set in an elevation route of the position detection device installed on the cage of an elevator. The streamline shaped bodies are attachments 2, 3 which can be separated from a detection device main body 1. Additionally, a shape of a section of the upper and lower surfaces of the device is a shape pointed against the forwarding direction as a triangle. Consequently, even if the riding cage travels at high speed, sir resistance of the position detection device projected from the cage is small, and it is possible to restrain generation of sound through the air.

摘要： PURPOSE:To prevent wear of an elevator car guide roller and generation of cable contacting noise by pressing an elevator control cable in the cable direction on the pit side with the lower part of the car using an arm furnished in the lower part of the car, and making the cable hanging dimension smaller than the free hang dimension. CONSTITUTION:An elevator control cable 2 is installed near the center of gravity of an elevator car 1, and a cable guide device 4 is furnished in the lower part of the car 1 for pressing the cable 2 in the cable direction on the pit side. When the car 1 sinks to get the 1b position, elevator controlling cable 2b is pressed by the cable guide device 4 so that the hanging dimension of the cable is changed, and thereby the car 1b is prevented from touching the cable 2b. Because the risk of the car inclining is eliminated, wear of a car guide roller caused by the car lying eccentrically is precluded.

摘要： PURPOSE:To obtain an end floor safety device for an elevator which is constituted so that the precision for the installation space, number of detection points for position, and the swinging of an elevator cage can be neglected, when the elevator is in the long traveling and high speed operation. CONSTITUTION:In an end floor safety device 3, two switch driving arms 4a and 4b which move interlockingly are installed coaxially, and rollers 5a and 5b are installed on respective arms. In an elevator shift, operating cams 9 and 8 which are successively engaged with these rollers are arranged. The figure shows the constitution on the upper end floor side, and also the lower end floor side is similarly constituted. Accordingly, the swinging width of an arm for driving a switch can be widened, and the number of detection points can be increased with the installation space equal to the conventional, and the detection precision can be improved.
