287 Auxiliary support of column, from all kinds of clockwise and anticlockwise rotation frictions, cooperation rotation speed goes control to slow down, effective protection component resistance to compression folding
It is disconnected, also make the off time of failure that better safeguard protection be made full use of to slow down and control elevator, is reached by anti-band-type brake retarder 2
The effect of the Gear Reducer Optimal band-type brake of elevator car roof repair safety guard, reversed band-type brake not merely pressurize friction eceleration, and
It is the regulating descending speed for enhancing hawser positive and negative rotation.
The present invention is combined with each other by above-mentioned component, reaches the Gear Reducer Optimal of elevator car roof repair safety guard
The effect of band-type brake, reversed band-type brake not merely pressurize friction eceleration, but enhance the regulating descending speed of hawser positive and negative rotation, the angle of angular speed
Torque obtains intermittent control, to make elevator tenesmus in hoistway, makes full use of finite time to adjust hawser slowing effect, more
Ensure the safety of service personnel, does not lean on mechanical brute-force to break band-type brake device, effectively part of appliance is conserved, reduce accessory loss, with
This buffer for being divided into bottom to solve elevator car roof repair safety guard buffers car, and also one is the decelerations of car top
Device slows down to the winding of elevator flexible steel wire, while emergency stop band-type brake, can be excessive when elevator freely falling body reduction of speed, and hawser loses
Control, band-type brake are easy that band-type brake case is made to break to form anti-force, increase lapse rate instead while damaging component, make danger
Property it is inestimable, to service personnel debug car top safety guarantee deficiency problem.
Buffer 9 of the present invention is the last one link of elevator safety system, in elevator failure or accident
Play the role of buffering when crouching bottom, to alleviate the people in elevator or elevator from directly hitting, buffer 9 when in use,
Strike top first hits plate 901, forces upper cylinder body 904 westwards to move, the hydraulic fluid of lower cylinder body 912 passes through oil guiding hole stream
To upper cylinder body 904, then, buffer spring 909, which touches, hits plate 901, is acted on by the double-layer bumper of hydraulic pressure and spring, makes car
Slow down, when moving to certain position, be expressed to switch 906, alarm 908 is made to act on.
