Problems solved by technology

However, the problem with this solution is that even if it does keep the deceleration within the specified range, due to the short feedback reaction time, high force and sensing technology, this solution is complex and difficult to implement. expensive
In addition, complexity can create a risk of reliability problems in operation that, if they actually occur, could jeopardize the safety of passengers

Embodiment Construction

[0038] figure 1 A simplified schematic rear view showing an elevator in which an embodiment of the safety equipment of the present invention is employed. For the sake of clarity, some parts of the elevator, including the traction machine and ropes and related assemblies, and also the sliding guides on the guide rails and the guide rollers, have been omitted from the drawing. An elevator car 2 fitted in a car frame 1 and driven by a separate traction machine (not shown in the figure) is arranged to move in an elevator hoistway 11 along guide rails 4 in a substantially vertical direction. sports. In the upper part of the elevator shaft 11 there is a governor pulley 8 included in the governor 7 and in the lower part a deflection pulley 9 included in the governor 7 . Fitted in loops around these pulleys is a governor rope 10 under appropriate tension.

[0039] The car frame 1 is provided with two safety devices 12 and 13, each comprising two safety mechanisms, mounted on the ou...

Abstract

The invention relates to an elevator provided with a safety gear arrangement, said elevator comprising at least an elevator car (2) arranged to travel back and forth substantially vertically along guide rails (4), at least two safety gear mechanisms (12, 13) disposed in conjunction with the elevator car (2) and at least one speed limiter (7), which comprises at least a speed limiter pulley (8), adiverting pulley (9) and a speed limiter rope (10) fitted as a loop around at least the speed limiter pulley (8) and the diverting pulley (9), said speed limiter rope (10) being connected at least toa first safety gear mechanism (12). A second safety gear mechanism (13) has been arranged to be triggered after the triggering of the first safety gear mechanism (12).

Description

technical field [0001] The invention relates to an elevator equipped with safety equipment as disclosed in the preamble of claim 1 . Background technique [0002] According to safety regulations, elevators need to be equipped with equipment for monitoring the speed of the elevator car and for stopping the movement of the elevator car if a predetermined maximum speed is exceeded or the elevator stops at a certain floor and starts to move without receiving a command. An overspeed situation may arise, for example, if the hoisting ropes of the elevator start to slip due to insufficient friction or if the hoisting rope breaks, the control system fails, or if the traction sheave shaft breaks and the elevator begins to fall freely in the elevator shaft. The aforementioned speed monitoring equipment usually includes at least a speed limiter to monitor the speed to ensure that the maximum speed will not be exceeded, and a safety device constituting a pair of safety mechanisms connect...
