Definitions
- the present invention relates to a device for Limitation of the vibration amplitudes of suspension elements and Compensatory means for an elevator with one in guides running counterweight.
- the suspension means and the compensating means the tendency to go in the horizontal direction swing.
- the stimulus to these vibrations has different causes.
- the driving operation itself is one of the Main causes.
- driving with great speed and deceleration arise, caused by small deviations in the vertical the guide rails, small horizontal movement components with the cabin and with the counterweight.
- This horizontal Movement components stimulate the suspension and compensation means horizontal vibrations, the deflection in Natural resonance range of the funds can be so large that mutual touches, as well as touches Chimney equipment occur, causing damage to Parts of the system and disruption of driving operations.
- U.S. Patent No. 4,117,908 shows a device consisting of a vibration suppressor under the Engine room ceiling in the shaft and another on the Cabin. These are constructed as frame-like structures and have stops which are placed close to suspension cables and a more or less large distance from Have the top of the cabin or the engine room ceiling. If Rope vibrations occur, for example as a result of earthquakes, so the vibrations from the cabin and from the Drive engine kept away, but not essential itself limited.
- the Vibration suppression made on the cabin side.
- the reasoning underlying the present invention is that the bigger one on the cabin side Vibration deflections are necessary than on the Counterweight side until the supporting and / or compensating elements attach to a fixed or movable part of the system.
- the invention was based on the object Device for limiting the vibration amplitudes of Suspension and compensation means on the counterweight side too create that is simple and inexpensive, any Touching the suspension and / or compensating means with Prevents parts of the system and those with extreme rashes offers additional security.
- the advantages of the invention include by that the establishment with static means without mechanical moving parts is running and that all over Head protects against large lateral deflections of the Suspension and compensation means is effective.
- Another advantage is that in extreme situations an additional safety device responds.
- the invention is based on a Exemplary embodiment illustrating the drawing.
- supporting and Compensating means are all types of suspension and Compensating means, e.g. Ropes, chains, tapes, cables and to understand encased means.
- 1 denotes a counterweight, which runs in guide rails 3 by means of guide devices 2.
- the counterweight 1 is on its upper side on suspension means 4 hung in the form of ropes, and on its underside are compensating means 5, also in the form of ropes attached. 6 with a bounding box is designated the guide rails 3, the counterweight 1, the suspension means 4 resp. the compensating ropes 5 encloses.
- the supporting structure is through a frame profile 9 is formed, the two parts of each with two curved ends are completed, which behind the Guide rails 3 in a mounting plate 11 with a Stop part 10 open.
- On the even parts of the Frame profile 9 are cylindrical rollers 7 and on the curved parts spherical rollers 8 with their axes of rotation arranged parallel to the horizontal.
- the Fig.3 shows the attachment and storage of the Boundary 6, respectively.
- the frame profiles 9 are on their ends with a plate-shaped frame end piece 12 completed and connected to each other with springs 13.
- the Frame end pieces 12 lie with their outermost edges Spring force on stop shoulders 15 of stop parts 10 on, which is firmly connected to the mounting plate 11 are.
- the mounting plates 11 are on the guide rail 3 clamped with claws and can vertically shifted and fixed at any point become. In the normal position shown, the Frame end pieces 12 monitoring switch 14 loaded and whose contacts are closed. The contacts are for example connected in series and part of the elevator safety circuit.
- the bounding frame 6 forms with all in FIGS. 2 and 3 parts shown a complete self-contained and prefabricated assembly. As dimensions to be adjusted are the track width of the counterweight rails 3 and the thickness of counterweight 1 is taken into account. Per elevator system can the bounding frame 9 in one or more copies can be installed by simply connecting to the Guide rails 3 of the counterweight 1. The vertical Distance between two bounding frames 9, depending on Suspensibility of the suspension or compensation means 4 or 5, for example values between five and ten meters exhibit. The lowest bounding box is as close as possible in the lower deflection loop of the compensating means 5 attached because there the translational rashes of Compensatory 5 will be the largest.
