Abstract
A traction mechanism with a shared counterweight for respectively towing each cage features that a steel cable passes through two towing wheels, its both ends are connected to two cages, and a group of counterweight blocks with equal mass is hung via moving pulleys from the steel cable between two towing wheels. Two counterweights can slide relatively. As a result, the street cable is always stressed and two cages can move up and down individually or synchronousely.
Description
Technical field
The present invention relates to the traction of a kind of shared counterweight separating transmission type, excellent its is the carrying means that is suitable for the steel rope transmission of various elevators and building hoist.
Background technology
At present, the carrying means of known various elevator and building hoist electricity car (cage), steel rope, traction sheave and to reassembling into.With one group of steel rope around being enclosed within on the traction sheave, one end of steel rope is connected with car (cage), the other end with to reconnecting, counterweight of an i.e. car (cage) configuration, the distribution of load of every steel rope is regulated by stretching device, and adjusting is very difficult, in use, often occur producing wire cable rupture and jumping phenomena, so influence the safety and the stationarity of complete machine operation because of the steel rope distribution of load is inhomogeneous.
Summary of the invention
In order to overcome the even deficiency of regulating difficulty of the wire rope load skewness that exists in the existing carrying means, the invention provides a kind of shared counterweight separating transmission type drawing mechanism.This carrying means adopts the shared counterweight of two cars (cage), makes complete machine structure more simple, and wire rope load distributes by the gravity automatically regulating to pouring weight, and every steel rope is in equal tensioning state all the time, and complete machine operates steadily, safe and reliable.
The technical scheme that problem adopted that the present invention solves its technology is: adopt the shared counterweight of two cars (cage), with one group of steel rope respectively on the traction sheave that is enclosed within two groups of independent drives, two ends of steel rope are connected with two cars (cage), one group are suspended between two groups of traction sheaves on the cooresponding steel rope by movable pulley pouring weight again.Under action of gravity to pouring weight, every steel rope is all the time in the tensioning state that equates, when the independent or synchronous positive and negative rotation of two groups of traction crop rotations, under the effect of friction, two cars (cage) are then made independently rise and fall campaign or synchronous move toward one another up and down.
Of the present inventionly with beneficial effect really be, wire rope load distributes very evenly, and need not regulate, and complete machine operates steadily, and is safe and reliable, simple in structure, uses easy to maintenance.Two cars (cage) both can be done independently rise and fall campaign, can make synchronous move toward one another up and down again.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a fundamental diagram of the present invention.
Among the figure 1, car (cage), 2, steel rope, 3, traction sheave, 4, traction sheave, 5, car (cage), 6, movable pulley, 7, to pouring weight.
The specific embodiment
In Fig. 1, one end of one group of steel rope (2) is connected with car (cage) (1), then around being enclosed within on one group of traction sheave (3), by organizing on traction sheave (4) around being enclosed within another again behind the movable pulley (6), the other end is connected with car (cage) (5), movable pulley (6) is fixed on the pouring weight (7), since all hanging on each root (or two) steel ropes (2) equal mass to pouring weight (7), and each is to pouring weight (7) and to (vertical direction) slip certain distance Δ S about being free between the pouring weight (7), Δ S preferably is no more than the millesimal of steel rope length overall, under action of gravity to pouring weight (7), every steel rope (2) all is in equal tensioning state all the time, when traction sheave (3) and the independently positive and negative rotation of traction sheave (4) do, under the effect of the friction between steel rope and the traction sheave grooving, car (cage) (1) and car (cage) (5) are done independently to rise or descending motion, this moment movable pulley (6) and then may be in rising to pouring weight (7), descend or static three kinds of different conditions.When traction sheave (3) and traction sheave (4) are done synchronous positive and negative rotation, and car (cage) this moment (1) and car (cage) (5), one is in bottom position, and another is in top layer (or the required layer that stops) position, under the effect of the friction between steel rope and the traction sheave grooving, car (cage) (1) and car (cage) (5) are then made synchronous move toward one another up and down, and this moment, movable pulley (6) and to pouring weight (7) then was in relative static conditions.
Claims (3)
1, a kind of shared counterweight separating transmission type drawing mechanism, be being connected between steel rope and car (cage), counterweight and the traction sheave, it is characterized in that: adopt the shared counterweight of two cars (cage), two ends of one group of steel rope are connected with two cars (cage), in spaced winding be enclosed within two groups independently on the traction sheave, one group is suspended between two groups of traction sheaves on the cooresponding steel rope by movable pulley pouring weight.
2, shared counterweight separating transmission type drawing mechanism according to claim 1 is characterized in that movable pulley is fixed on the pouring weight, and each quality to pouring weight equates that all its error is no more than 10%.
3, shared counterweight separating transmission type drawing mechanism according to claim 1 is characterized in that each is to pouring weight and to (vertical direction) slide relative about being free between the pouring weight.
