Abstract
The invention provides a wire rope tension automatic balancing rope end device capable of automatically balancing the tension of an elevator wire rope so as to improve the comfort degree of elevator operation, prolong the service life of the wire rope and reduce the workload of field adjustment and maintenance. An initial end and a terminal end of the wire rope are respectively fixed on a car side pulley block and/or a counter-weight side pulley block; and a middle section of the wire rope repeatedly bypasses a traction sheave, a pulley and a traction sheave on the car side pulley block, and a pulley on the counter-weight side pulley block.
Description
Technical field
The present invention is a kind of steel wire rope tension self-equalizing fag end device.
Technical background
At present, the traction elevator of the various uses that in building, is provided with, according to its load carrying ability, speed, principal parameters such as hoisting depth, by the calculating of safety coefficient, general traction elevator will dispose several steel ropes.Like this, in elevator installation and debug process,, need the commissioning staff to adjust the elasticity of steel rope, thereby make several steel wire rope tension equilibriums in order to make the elevator operation more comfortable.But in actual Engineering Projects, the tension force complete equilibrium of several steel ropes often can not 100% realizes that it is stressed bigger to cause adjusting tighter steel rope, and the steel rope of adjusting pine is stressed less.When steel rope and rope sheave engagement, the vibration of generation interferes with each other, and influences the comfort level of elevator operation, and the service life of having reduced steel rope, and on-the-spot adjustment maintenance workload is also bigger.And the command speed of elevator is high more, and such phenomenon is obvious more.
Summary of the invention
The purpose of this invention is to provide a kind of tension force automatic equalization that makes the elevator traction steel rope, thereby improve the comfort level of elevator operation, prolong the service life of steel rope, reduce the on-the-spot steel wire rope tension self-equalizing fag end device of adjusting maintenance workload.
This towed elevator steel wire rope tension self-equalizing fag end device, the initiating terminal and the clearing end that are steel cable are separately fixed on cage side pulley base and/or the counterweight sideslip wheel seat, and the interlude of steel rope is walked around the pulley on pulley on traction sheave, the cage side pulley base, traction sheave, the counterweight sideslip wheel seat repeatedly.
Described fag end device can be that the initiating terminal of steel cable is fixed on the cage side pulley base, and this steel rope is walked around traction sheave then, walk around the pulley of counterweight sideslip wheel seat, walk around traction sheave, walk around the pulley on the cage side pulley base after, walk around traction sheave again, walk around again on the pulley of counterweight sideslip wheel seat, walk around traction sheave again, walk around the pulley on the cage side pulley base again, walk around traction sheave again, the rest may be inferred, and the clearing end of steel rope is fixed on cage side pulley base or the counterweight sideslip wheel seat.
Described fag end device can also be that the initiating terminal of steel cable is fixed on the counterweight sideslip wheel seat, and this steel rope is walked around traction sheave then, walk around the pulley of cage side pulley base, walk around traction sheave, walk around the pulley on the counterweight sideslip wheel seat after, walk around traction sheave again, walk around again on the pulley of cage side pulley base, walk around traction sheave again, walk around the pulley of counterweight sideslip wheel seat again, walk around traction sheave again, the rest may be inferred, and the clearing end of steel rope is fixed on cage side pulley base or the counterweight sideslip wheel seat.
Above-mentioned fag end device, the interlude of steel rope are walked around the pulley on pulley on traction sheave, track adjusting wheel, the cage side pulley base, track adjusting wheel, traction sheave, the counterweight sideslip wheel seat repeatedly.
Because steel rope of the present invention is actual is that steel cable is by the fixing middle mode of walking around pulley in two ends, whenever walk around a pulley and be equivalent to one of traditional steel rope radical increase, but in fact with independently mode is different separately between traditional steel rope root and the root, therefore, when the steel rope bearing load, tension force on every steel rope is balanced, i.e. tension force=total weight on every steel rope/walk around number of share of stock of pulley.That is to say that the number of times of walking around pulley by steel cable forms number of share of stock, thereby replace in original traditional mode independently steel rope radical, reach the purpose of automatic equalization.Therefore no matter the traction steel-cable number of share of stock what, can be by this fag end device with the balancing tension of each strand steel wire rope.It is applicable to various traction elevators, such as passenger elevator, and sightseeing elevator, Medical Service Elevator, cargo lift etc.
