Detailed description of the invention
As can be seen from Fig. 1, Fig. 2: a kind of traction drive elevators, it is characterized in that comprising load-carrying element 3, pulley, suspender 5, threaded shaft 9, movable block 10.Movable block 10 is threaded hole.Nested together by screw thread between movable block 10 and threaded shaft 9.Suspender 5 is walked around pulley and is connected on movable block 10.Like this, threaded shaft 9 rotation can drive movable block 10 to move, thus affects suspender 5.So the weight that suspender 5 hangs or bay-lift 6 can realize lifting.
Whole elevator comprises load-carrying element 3, wheel 7, hub brake, pulley, suspender 5, bay-lift 6, movable block 10, threaded shaft 9, bearing, axis fixing plate 8, axle mounting ring and wind 2.
Load-carrying element 3 is provided with wheel 7 and hub brake.This wheel 7 is cardan wheels.This hub brake by pressing brake lining thus affecting the steel wire in brake rubber block, and then blocks and rigidly connectedly with wheel shaft has toothed disc.Press brake lining, brake lining just blocks by the dop be connected with spring, and wheel 7 is just braked, and pushes dop aside, and brake lining playbacks under the action of the spring, and braking is just removed.Load-carrying element 3 is provided with several fixed pulleys and several movable pulleys.If do not need laborsaving by pulley or change distance, so the number of movable pulley can be zero.The assembly pulley of these pulleys composition, can also as required for laborsaving or change distance for changing the direction of suspender 5.Load-carrying element 3 is liftable.Before lifting weight, regulate the length of the strut bar of load-carrying element 3, be then stuck with buckle fixed pedestal bar, i.e. the height of adjustable supporting component 3.
Axis fixing plate 8 is provided with two axle mounting rings.A threaded shaft 9 is through axle mounting ring.Movable block 10 is threaded hole.Nested together by screw thread between movable block 10 and threaded shaft 9.Movable block 10 is with two small wheels.Wheel on movable block 10 contacts with axis fixing plate 8 just, so movable block 10 can be avoided to rotate with threaded shaft 9, and friction when simultaneously also can reduce movable block 10 parallel motion and between axis fixing plate 8.In one end of threaded shaft 9, be connected by bearing between threaded shaft 9 and axle mounting ring, threaded shaft 9 can be prevented like this from slippage axle mounting ring, and reduce friction when threaded shaft 9 rotates and between axle mounting ring.Threaded shaft 9 is equipped with wind 2.Axis fixing plate 8 is installed on load-carrying element 3.Detouchable between axis fixing plate 8 and load-carrying element 3.
Suspender 5 is bent elongated objects, can be hoisting chain, steel rope, the rope made of hemp, suspender belt etc.Suspender 5 is walked around pulley and is connected on movable block 10.Elevator can with many suspenders 5, and these suspenders 5 walk around assembly pulley by respective mode, are connected to movable block 10 from identical direction.
At the lifting end of suspender 5, connect bay-lift 6 or directly connect weight.Suspender 5 is connected removably with between bay-lift 6 or weight.Bay-lift 6 can be one flat plate, also can have different shapes and structure according to the demand of reality.Bay-lift 6 is for holding weight.
When elevator has four suspenders 5, the both sides at load-carrying element 3 top are respectively equipped with two fixed pulleys 4, and on the side of load-carrying element 3, both sides are respectively equipped with a fixed pulley 1.In the side of load-carrying element 3, the fixed pulley 4 with each self-corresponding load-carrying element 3 top walked around by two suspenders 5, and walks around the fixed pulley 1 on load-carrying element 3 on this side, side, is connected on movable block 10.At the opposite side of load-carrying element 3, the fixed pulley 4 with each self-corresponding load-carrying element 3 top walked around by two suspenders 5, and walks around two fixed pulleys 1 on load-carrying element 3 side, is connected on movable block 10.Like this, four suspenders 5 are just connected from identical direction with movable block 10.
During use, shake wind 2 makes threaded shaft 9 rotate, thus movable block 10 is moved, and then affects suspender 5, realizes bay-lift 6 or weight lifting.By regulating the height of load-carrying element 3, the maximum height that elevator can be elevated can be regulated.
