Problems solved by technology

However, a problem with these kinds of solutions is that it is difficult to precisely adjust the top speed to the desired size
Another problem is that these adjustments are not always the same, one of them is because of the fact that the overspeed regulator is triggered very rarely, due to this, for example, the characteristics of the springs that are housed in this facility will change over time
There is also the problem that overspeed regulators based on centrifugal force cannot be made very small, as their sensitivity would become excessive with reduced size

Embodiment Construction

[0021] figure 1 Shown is a schematic simplified view of a traction grooved wheel elevator without counterweight, applicable to installations according to the invention, comprising at least an elevator hoist 5 with a hoisting motor, traction grooved wheels 6, elevator The control system 8 and the elevator car 1 are located in a car hanger 2 moving along the guide rail 4 in a substantially vertical direction, the car hanger 2 being suspended on hoisting ropes 3 . The first end of the hoisting rope 3 is fitted to the top of the car hanger 2, from which point the hoisting rope 3 is guided over the traction sheave 6 and then under the diverting pulley 7 of the hoist 5 , and then go around again above the traction grooved pulley 6, from here, the hoisting rope 3 extends to below the diverting pulley 9 installed at the bottom of the elevator shaft, and then extends to the bottom of the car hanger 2, lifting The second end of the lanyard 3 is installed here. The elevator receives li...

Abstract

The object of the invention is an arrangement in the overspeed governor of an elevator, which elevator comprises at least one safety gear (12b) disposed in connection with the elevator car (1) as well as an overspeed governor (10). The overspeed governor comprises at least an overspeed governor pulley (12), the rope (11) of the overspeed governor and also a frame (13) and a locking element (15) with its axis of rotation (20) for stopping movement of the overspeed governor rope (11), which locking element (15) is arranged to turn around its axis (20) when the overspeed governor trips. The overspeed governor (10) further comprises permanent magnets (17) for forming a magnetic field. When the overspeed governor trips, the locking element (15) is arranged to move, in addition to its turning movement, essentially in the direction of the radius of its axis of rotation (20).

Description

technical field [0001] The object of the invention is a construction of an elevator overspeed governor as defined in the preamble of claim 1 . Background technique [0002] According to safety regulations, elevators must include certain facilities that monitor the speed of the elevator and stop the movement of the elevator car if the set maximum speed is exceeded. Such installations generally include at least one overspeed governor that monitors that the maximum speed is not exceeded and a safety device mounted to the elevator car or car hanger and connected to the overspeed governor, when the overspeed governor is triggered in the event of overspeed, The safety device stops the elevator car. Elevator overspeed governors are generally mechanical rope systems in which, for example, the overspeed governor pulley is located on bearings that allow rotation in the top of the elevator shaft, the diverting pulley is at the bottom of the elevator shaft, and a closed loop of overspe...
