The technical scheme that realizes above-mentioned purpose is:
A kind of improved jacking system with interlock car, comprise first car, first hawser, damping arrangement, second car, second hawser, the first traction fixed pulley and the second traction fixed pulley, one end of described first hawser of top captive joint of described first car, be subjected to the top of described second car of other end captive joint of described first hawser of damping arrangement control rate, the bottom of described second car of one end captive joint of described second hawser, the other end of described second hawser is captiveed joint the bottom of described first car behind the fixed pulley through the second traction fixed pulley and first traction and is constituted and make first car and second car make reciprocating one on the other closed loop path
Further, also comprise the 3rd traction fixed pulley and the 4th traction fixed pulley, described the 3rd traction fixed pulley is arranged between described first car and the damping arrangement, be used to draw first car, described the 4th traction fixed pulley is arranged between described damping arrangement and described second car, is used to draw second car.
Further, described first hawser is identical with the weight of the unit length of second hawser, make and win car and second car when no-load run, when any one car is in any height, the hawser weight between the damping arrangement and the first traction fixed pulley be equal in weight at the damping arrangement and second hawser that draws between the fixed pulley.
Being equal in weight of described first car and second car.
Adopt technique scheme, beneficial technical effects of the present invention is:
1, by second hawser, the first traction fixed pulley and second structures such as traction fixed pulley etc. are set, make to constitute closed loop path between first car and second car, the lifting of car can not be subjected to the influence of hawser changes in weight, regardless of different kinds of the load car all energy is descending.Break through the height-limited difficult problem of use of interlock car population self-help escape equipment, be particularly suitable for the high-rise building more than 100 meters.And, instant singlely still can implement self-help escape!
