Abstract
The invention provides an automatic tension balancing rope head device for a steel wire rope, which is used for automatically balancing tension of an elevator dragging steel wire rope to improve the running comfort of an elevator, prolong the service life of the steel wire rope and lower field adjustment and maintenance workloads. The starting end of a steel wire rope of the device is fixed on a cage side pulley seat; the middle section of the steel wire rope is repeatedly wound on a dragging wheel, a pulley on the cage side pulley seat, a dragging wheel and a pulley on a counterweight side pulley seat; and the termination end of the steel wire rope is fixed on the cage side pulley seat or the counterweight side pulley seat.
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, through 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 adjustment steel rope of 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 steel wire rope tension self-equalizing fag end device of on-the-spot adjustment maintenance workload.
This steel wire rope tension self-equalizing fag end device; The initiating terminal of steel cable is fixed on the cage side pulley base; 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, and the clearing end of steel rope is fixed on cage side pulley base or the counterweight sideslip wheel seat.
Described fag end device, the interlude of steel rope is walked around traction sheave, walks 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.
Because steel rope of the present invention is actual is that steel cable is through 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 through 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 through 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.

The specific embodiment
Referring to Fig. 1,3; Steel wire rope tension self-equalizing fag end device comprises; Cable wire end 7 (comprising steel rope initiating terminal 71, steel rope clearing end 72), steel rope 9 and be used for self-balanced pulley 6 and the pulley base (comprise cage side pulley base 1 with counterweight sideslip wheel seat 2) etc. of pulley 6 is set.
Cage side pulley base 1 is fixed on car 3 one sides.Counterweight sideslip wheel seat 2 is fixed on counterweight 4 one sides.Steel rope initiating terminal 71 (causing with conventional cord is first) is fixed on an end of cage side pulley base 1.Steel rope is walked around traction sheave 5, returns on the pulley of the counterweight sideslip wheel seat 2 of the track adjusting wheel grooving arrival other end, walks around traction sheave; The track adjusting wheel grooving arrives at the pulley on the cage side pulley base 1, walk around the pulley on the cage side pulley base 1 after; Turn back to the pulley on the counterweight sideslip wheel seat 2 again, walk around the pulley on the counterweight sideslip wheel seat 2 after, return again; The rest may be inferred, until satisfying steel rope 9 radicals (number of share of stock) that are fit to.When steel rope radical (number of share of stock) was even number, steel rope clearing end 72 was fixed on cage side pulley base 1, sees Fig. 2.When steel rope radical (number of share of stock) was odd number, steel rope clearing end 72 was fixed on the counterweight sideslip wheel seat 2, sees Fig. 5.
Technical characterstic of the present invention is that pulley base is fixed on car and counterweight one side.Said cable wire end (causing with conventional cord is first) is fixed on an end of a pulley base (can be referred to as the initiating terminal pulley base, can be cage side pulley base 1, also counterweight sideslip wheel seat 2).Steel rope is walked around traction sheave, returns on the pulley of track adjusting wheel grooving another pulley base of arrival (can be referred to as the clearing end pulley base), walks around traction sheave; The track adjusting wheel grooving arrives at initiating terminal pulley base top sheave, walk around the initiating terminal pulley after; Turn back to clearing end pulley base top sheave again, walk around clearing end pulley base pulley after, return again; The rest may be inferred, and after satisfying the steel rope radical that is fit to, cable wire end is fixed on the pulley base.When steel rope radical (number of share of stock) is even number; Steel rope initiating terminal and steel rope clearing end all are fixed on the initiating terminal pulley base; When steel rope radical (number of share of stock) was odd number, the steel rope initiating terminal was fixed on the initiating terminal pulley base, and the steel rope clearing end is fixed on the clearing end pulley base.
The present invention is applicable to that lanyard is than n: 1 (n is a natural number).This fag end device is applicable to the elevator suspension system, both has been applicable to the traction elevator of direct drive, also is applicable to the traction elevator of indirect driving.
