Abstract
The utility model relates to the tension balancing device of a traction wire rope, comprising a row of fixed pulleys which are arranged at the upper side part of a hanging piece in sequence. The tension balancing device of the traction wire rope is characterized in that a movable pulley is arranged above the space between every two adjacent fixed pulleys; a chain bypasses reciprocally the fixed pulleys and the movable pulleys; the head end and the tail end of the chain respectively bypass the movable pulleys at the head end and the tail end, and then are fixedly connected with the upper side part of the hanging piece; the distance from the fixed ends of two chains to the central line of two fixed pulleys at the head end and the tail end is equal to the distance from the central line of any one fixed pulley to the tangent line of an adjacent fixed pulley; and the traction ropes of all movable pulleys are aggregated into a whole, thereby leading the stress of each traction rope which is connected on the movable pulley to be uniform. The device can effectively ensure that the stress of each traction wire rope used by the hanging piece is uniform.
Description
Technical field
The utility model relates to a kind of traction steel-cable equalizer, particularly a kind of traction steel-cable balancing tension device that is applicable to that hanging piece is used.
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 purpose of this utility model is to provide a kind of traction steel-cable tension balance device, and this device can guarantee effectively that each traction steel-cable that hanging piece uses is stressed evenly.
Of the present utility model being characterised in that: 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 utility model is: the traction steel-cable tension balance device 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.
Advantage of the present utility model is: 1, this balancing device 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 balance device structure compactness, 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 balance device structure is simple, 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 balancing device 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.
5, this balancing device not only can be applicable on the elevator, also can be applicable on the equipment that use steel ropes such as all kinds of hoisting cranes, winch, rope pulley, assembly pulley, coaster, recreation car, lifting transportation or chain lift by crane.
