Abstract
The invention relates to a drag rope balancer for a hanger, comprising a row of fixed pulleys which are sequentially distributed on the upper side of the hanger. The drag rope balancer for the hanger is characterized in that a movable pulley is arranged above the position between every two adjacent fixed pulleys, a chain rounds the fixed pulleys and the movable pulleys in an oscillating mode, the head end and the tail end of the chain respectively round the fixed pulleys of the head end and the tail end and are fixedly connected with the upper side of the hanger, the distance from two chain fixed ends to a center line of the two fixed pulleys of the head end and the tail end is equal to the distance from a center line of any one fixed pulley to a tangent line of the adjacent fixed pulleys, drag ropes of the movable pulleys are integrated into a whole, and the drag ropes which are connected with the movable pulleys are evenly stressed. The drag rope balancer for the hanger can effectively ensure the even stress of the drag ropes of the hanger.
Description
Technical field
The present invention relates to the traction steel wire equalizer that a kind of hanging piece is used, particularly a kind of elevator traction steel wire equalizer.
Background technology
Along with developing rapidly of China's economic construction, the rapid raising of the people's material and cultural life level, the skyscraper of various places stands in great numbers, and large quantities of residence building groups are constantly built.Follow the development of building industry, for the elevator industry that communications and transportation up and down is provided in the building develops also with rapid changepl. never-ending changes and improvementsly.Elevator has been not only the visual plant in a kind of production link, the essential equipment of a kind of especially economic activity and daily life.Therefore, people pursued safe, reliable, comfortable, elevator demand surge efficiently; Certainly, the performance of lift product and quality receive increasing concern.
The fixed form of elevator traction steel rope is that the end with many steel ropes is fixed on the upper beam of lift car frame and counterweight frame mostly.Because steel rope is different in size to be caused,, directly influence its functional reliability and service life so every steel rope is stressed also different.Existing technology is in fag end and upper beam junction, designs one section screw rod and overlaps upper spring.By the length of adjusting screw(rod), the balancing force that changes spring is adjusted the stressed of every traction steel-cable, and then makes every effort to the stressed unanimity as far as possible between the many steel ropes.Therefore, the balance of traction steel-cable tension force is and is crucial that have only the every tension force basically identical that steel rope is suffered, the operation of elevator, especially express elevator could be more steady; The life-span of traction steel-cable and traction sheave could prolong more.Yet existing elevator hitch is to realize by manual operation to the adjustment of its traction steel-cable tension force fully.Usually, the artificial adjustment entirely tested the tension force size with the feel of elevator setter, and error is serious, so adjust poor accuracy, this protection to elevator operation and traction steel-cable and application wheel is very disadvantageous.
Summary of the invention
The traction steel wire equalizer that the object of the present invention is to provide a kind of hanging piece to use, this device can guarantee effectively that each traction steel-cable that hanging piece uses is stressed evenly.
The invention is characterized in: the top between the described per two adjacent fixed pulleys is provided with a movable pulley, a chain back and forth coiled fixed pulley and movable pulley, captive joint with the hanging piece upper lateral part after walking around the movable pulley of two ends respectively in the two ends of described chain, two chain fixed ends equate with the distance of arbitrary fixed pulley line of centers to adjacent fixed pulley tangent line with the distance of two fixed pulley line of centerss of head and the tail, the hauling rope of each movable pulley is combined into one, makes each hauling rope that is connected on the movable pulley stressed evenly.
Work structuring of the present invention is: elevator traction steel rope equalizer comprises chain and chain pulley group.The chain fixed pulley is bearing in the below that car frame or counterweight frame are put the beams in place through fixed pulley anchor shaft and U-bolt; One end of chain movable pulley and fag end combination is hinged; Chain is walked around chain fixed pulley and chain movable pulley successively, and the chain two ends also are fastened on car frame or the counterweight frame by the chain connecting element.Traction steel-cable is carved pattern by filled type or self-locking and is connected with the other end of fag end combination, and hangs on the two ends of the traction sheave of elevator traction machine through the steel rope track adjusting wheel.Track adjusting wheel is bearing on the track adjusting wheel adapter plate, is connected by the straight beam of bolt of rear end plate with car frame or counterweight frame.
The invention has the advantages that: 1, this equalizer fag end of being used for the elevator traction steel rope is fixed, and tension force that can many steel ropes of self-equalizing makes all steel ropes be in the balancing tension state forever.
2, this equalizer compact conformation, reliable in action in the service life of effectively improving elevator traction wheel and steel rope, helps guaranteeing elevator reliability of operation and stationarity.
3, this equalizer is simple in structure, and machinework is easy, and especially, device is installed very convenient, compares with existing suspension gear, can obviously save the installation and debugging time, improves installation effectiveness.
4, one of these equalizer characteristics are that chain has only one, two ends are fixed on car frame or the counterweight frame upper beam, when installing or keeping in repair, as long as regulate the relative position of any one chain movable pulley, the tension force of each bar steel rope is just equivalent simultaneously to be changed, so the adjustment of this device is easy to, and on mechanism, keep the uniform tension in order of each steel rope.

Fig. 1 is a structural representation of the present invention.
The specific embodiment
The traction steel-cable equalizer that a kind of hanging piece is used, comprise and be laid in one of hanging piece upper lateral part 1 pulley 2 that is ranked successively, top between the described per two adjacent fixed pulleys is provided with a movable pulley 3, a chain 4 back and forth coiled fixed pulley and movable pulley, the two ends 5 of described chain, 6 captive joint 7 with the hanging piece upper lateral part after walking around the movable pulley of two ends respectively, two chain fixed ends equate with the distance of arbitrary fixed pulley line of centers to adjacent fixed pulley tangent line with the distance of two fixed pulley line of centerss of head and the tail, the hauling rope 8 of each movable pulley is connected with movable pulley through fag end combination 9, described hauling rope is combined into one, and each hauling rope that can guarantee to be connected on the movable pulley is stressed evenly.
Described hanging piece is an elevator traction steel rope equalizer with the traction steel-cable equalizer, and described hauling rope is combined into one through track adjusting wheel 10.
