According to its laborsaving principle of laborsaving lever, the power of 1/2nd can be economized with bracing wire hoisting movable pulley, several fixed pulleys selecting same bracing wire double or many rows of level or vertical or oblique arrangement to be rotated for original position and movable pulley fit back and forth, wherein one is pulled by manpower or power, other end top system is hung on static body, its interlude is for bearing by the weight promoting object, according to pulley number and be the intensity of weight bracing wire and the length of hanging object, more laborsaving its pulley quantity is correspondingly more mostly is proportional relation, its reason is that equal heavy burden shared by each pulley.Its specific practice is: be installed on by several fixed pulleys on two static supports, by equal or to be installed on middle same close to the movable pulley of equivalent amount can oscilaltion and top, its lower end be the pull bar of a hook or cotton rope (its hook and cotton rope for be that extension is promoted or drawn the object moved), also can with framework substitution hook and cotton rope for holding by the object promoted, by bracing wire from top to bottom left and right back and forth (or be situation) conversely by each pulley winding fit, each pulley and bracing wire are affixed girth and are no more than 180 °, the top, lower end of bracing wire is fixed therein on the support of a side, other end system hangs and is wrapped on the roller that drives with manpower or power.

It is one group with single bracing wire and by its pulley surmounted and regarding repair parts, such combination can be single combination according to technological requirement, two combination or combine more, when for single combination above time be placed in same level, top, the lower end stay of each root pull bar involves and is integrated, respectively be combined in same level and can be arranged as oblong or square or polygon, as long as carry additionally more than single or two or two hooks in its bottom for being extension weight, namely the weight of same or two or more object is born in many combinations jointly, increase the number of pulley and just can realize reducing tractive force and energy-conservation.Such device both can be vertical dress (pull bar is vertical) depending on technological requirement, and also can be paperback (pull bar level) or angle mount, because cotton rope can be turned, paperback and angle mount can be used for dragging weight, also may be used for lifting heavy.Two side stands and centre link can being allowed some leeway, for installing pulley additional if desired, reaching with this pulling force increasing pull bar under the condition not increasing tractive force and power.

Its acting principle is: use manpower or power to pull to tighten up bracing wire to impel pull bar moves or after move, in movement by be hang over pull bar lower end or claim front end heavy lift or after move, its gravity is halved on each pulley, realize reducing tractive force and power with this, can save energy more than 0.9 at most according to pulley number; Loosening bracing wire impels pull bar and hook to decline for being extension object.

In sum, its main points of the technical scheme that the utility model adopts are: often group is the fixed pulley that rotates of original position and to be positioned at centre be the movable pulley fit back and forth that oscilaltion or front and back are shifted by bracing wire by being positioned at both sides, several fixed pulleys of both sides are arranged on static support, several movable pulleys middle are arranged on same pull bar, pull bar with single exist time its end top hook or cotton rope or framework are installed; With stay, two groups or more pull bar lower end or rear end are involved as a whole, and stay below or back hook or cotton rope or framework are installed; Two side stands and pull bar leave the leeway of installing pulley.

Its beneficial effect one of the utility model to improve work efficiency: its reason is when often organizing pulley number in many groups and being the same, pull many pull bars simultaneously and pull the time of single pull bar to be equal, and the hoisting force of double joint slide bar is single double, by that analogy, such as to same object and do not change power condition under, single pull bar needs installation 100 pulleys to be competent at, every root divided equally by ten pull bars is 10, one is divided into ten rear every single bracing wire length to shorten 9/10ths, namely the time of 9/10ths is saved, more light for use manpower, namely significantly reduce labour intensity and correspondingly improve work efficiency, two is that the many concordant combinations of pull bar can corresponding reduction mounting bracket height, and is convenient to resettlement and installs fast, three be the mode of increase and decrease pulley easy to use for increasing its hoisting force or reduce tractive force and power, the reduction of power had not only achieved and energy-conservation but also has correspondingly reduced the intensity of bracing wire and reduce cost.
