Description

Cord pulling type energy-saving elevator

Technical field

The present invention relates to lift a kind of equipment of object in other words for lifting heavy, it is more particularly more precisely to be elevator for being lifted or dragging a kind of device of weight.

Background technology

In regular job, heavy lift must be moved on the vehicles in loading process, moving article often just will enable through lifting or dragging, the more heavy required Dynamic response of object that is elevated or dragging is bigger, certain energy must be consumed as cost with more, different equipment are selected according to weight of object, such as chain block or electric block are all how much to carry out decision device model with its weight of suspended object part（Tonnage）, its crane similarly, thus it is single and be unfavorable for the disadvantages such as energy-conservation to there is purposes.

Content of the invention

The present invention is to overcome above-mentioned deficiency, it is desirable to provide a kind of equipment carrying or dragging that can correspond to various Different Weight objects within the specific limits, and can be preferably minimized power consumption and improve work efficiency, employs the following technical solutions and is achieved.

According to its laborsaving principle of laborsaving lever, 1/2nd power can be saved with bracing wire hoisting movable pulley, from same bracing wire by horizontally or vertically or just tiltedly double or multiple rows of several fixed pulleys for original position rotation of arrangement 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 used for bearing the weight of elevated object, according to pulley number and be the degree of weight bracing wire and the length hanging object, how laborsaving its pulley quantity is more mostly accordingly more to be proportional relation, its reason is that equal heavy burden all shared by a pulley.Its specific practice is：Several fixed pulleys are installed on two static supports, equal or close to equivalent amount movable pulley is installed on middle same can be come directly towards as a hook or cotton rope with its lower end in oscilaltion（Its hook and cotton rope are used for being to hang object that is elevated or being drawn shifting）Pull bar on it is also possible to framework substitution hook and cotton rope be used for hold elevated object, by bracing wire from top to bottom left and right back and forth（Or for situation in turn）Each pulley is wound around fit, each pulley and bracing wire are affixed girth and are less than 180 °, the lower end top of bracing wire is fixed therein on the support of a side, other end system hangs and is wrapped on the roller being driven with manpower or power.

The pulley surmounted with single bracing wire and by it and relevant accessory are one group, such combination can be that single group is closed according to technological requirement, double combinations or many combinations, it is placed in same level when closing above for single group, the lower end top stay of each pull bar involves and is integrated, each group is combined in same level and can be arranged as rectangle or square or polygon, as long as carry additionally single or double or more than double and link up with its bottom to be used for being extension weight, i.e. multigroup amount to bearing the weight of same or two or more objects, the number increasing pulley just can achieve and reduces tractive force and energy-conservation.Such device both can be vertical dress depending on technological requirement（Pull bar is vertical）Or paperback（Pull bar level）Or angle mount, because cotton rope can be turned, paperback and angle mount can be used for dragging weight it is also possible to be used for lifting heavy.Can allow some leeway on two side stands and intermediate draw bar, for installing pulley if necessary additional, be reached with this and do not increasing the pulling force increasing pull bar under conditions of tractive force is power.

Its acting principle be：Tighten up bracing wire using manpower or power pulling to promote to move on pull bar or rear shifting, movement will be heavy lift or the shifting afterwards hanging over pull bar lower end or claiming front end, its gravity halved on each pulley, realizing reducing tractive force with this is power, at most can save energy more than 0.9 according to pulley number；Loosening bracing wire promotes pull bar and hook decline to be used for being extension object.

In sum, its main points of the technical solution adopted in the present invention are：Group will be the fixed pulley rotating in situ positioned at both sides and is located at the middle movable pulley fit back and forth being oscilaltion or shifting in front and back by bracing wire, several fixed pulleys of both sides are arranged on static support, several movable pulleys middle are arranged on same pull bar, and pull bar is provided with hook or cotton rope or framework with its end top in the presence of single；With stay, two groups or more pull bar lower end or rear end are led and held together, and stay is following or back mounting hook or cotton rope or framework；The leeway installing pulley is left on two side stands and pull bar.

Its advantage one of the present invention is to improve work efficiency：When its reason is that every group of pulley number is the same in multigroup, pulls many pull bars simultaneously and pull time of single pull bar to be equal, and the lifting force of double joint slide bar is single double, by that analogy, for example to same object with conditions of not changing power, single pull bar needs to install 100 pulleys could be competent at, ten pull bars are divided every equally and are 10, one be divided into ten after often single bracing wire length shortened 9/10ths, save for 9/10ths time, more light for using manpower, that is, significantly reduce work degree and accordingly improve operating efficiency；Two is that the concordant combination of many pull bars can accordingly reduce mounting bracket height, and is easy to resettlement and installs quick；Three are easy for being used for increasing its lifting force using the mode of increase and decrease pulley or to reduce tractive force be power, and the reduction of power had not only achieved energy-conservation but also accordingly reduced the degree of bracing wire and reduce cost.
