Abstract
The utility model discloses a traction system for a freight elevator in a 4:1 small machine room, which comprises side guide wheels 1, counterweight wheels 2, a traction wheel 3, a traction rope 4, a counterweight body 5, overhead wheels 6 and a car sill 7 as well as a guide wheel 3A, wherein the guide wheel 3A is positioned between the traction wheel 3 and the overhead wheel 6; one end of the traction rope 4 passes through the traction wheel 3, the guide wheel 3A, the overhead wheel 6 and the side guide pulley 1 to a fixed rope head M in sequence, and the other end of the traction rope 4 passes through the traction wheel 3, the counterweight wheel 2 and the side guide wheel 1 to a fixed rope head N. The traction system solves the problems of deviation and abnormal abrasion of unilateral guide shoe and is widely applied to a 4:1 traction elevator.
Description
Technical field
The utility model belongs to the elevator field, relates in particular to the traction system of elevator, specifically, relates to the traction system design of 4:1 small room cargo lift.
Background technology
For the small room cargo lift of 4:1 traction, Fig. 1 is seen in existing traction system design.As shown in Figure 1, comprise side guide wheel 1, counterweight wheel 2, traction sheave 3, hoist ropes 4, counterweight body 5, crosshead sheave 6, car 7, described hoist ropes 4 one ends successively via traction sheave 3, crosshead sheave 6, side guide wheel 1 to fixing fag end M; The other end of described hoist ropes 4 successively via traction sheave 3, counterweight wheel 2, side guide wheel 1 to fixing fag end N.
The design's defective is: the diameter of (1) described traction sheave 3 is usually less than the distance of crosshead sheave 6 to counterweight wheel 2, and this can cause crosshead sheave 6 to the hoist ropes between the traction sheave 34 to tilt, and is unfavorable for the installation and operation of elevator; (2) owing to crosshead sheave 6 to the hoist ropes between the traction sheave 34 tilts, operation up and down along with car 7, the angle of inclination of this section hoist ropes 4 can change, cause that traction changes, and when cage side fag end M locatees when not accurate enough, the phenomenon of sideslip can appear because the horizontal component of the pulling force of both sides hoist ropes is unequal in car 7, will cause the monolateral boots heel and toe wear of leading like this.
Summary of the invention
At the weak point of current techniques, special a kind of new traction system design plan, the i.e. traction system of 4:1 small room cargo lift of proposing of the utility model.
The traction system of 4:1 small room cargo lift, comprise side guide wheel 1, counterweight wheel 2, traction sheave 3, hoist ropes 4, counterweight body 5, crosshead sheave 6, car 7, also comprise track adjusting wheel 3A, described track adjusting wheel 3A between described traction sheave 3 and described crosshead sheave 6, hoist ropes 4 one ends successively via traction sheave 3, track adjusting wheel 3A, crosshead sheave 6, side guide wheel 1 to fixing fag end M; The other end of described hoist ropes 4 successively via traction sheave 3, counterweight wheel 2, side guide wheel 1 to fixing fag end N.
In order to realize goal of the invention of the present utility model, reach the small room elevator, traction sheave 3 of the present utility model is driven by permanent-magnet synchnorous gearless dragging machine, this permanent-magnet synchnorous gearless dragging machine is applied among the man lift usually, in Cargo Lift, especially do not use in the large-tonnage cargo lift, because of it belongs to the especially general purpose module among the man lift of elevator, so repeat no more, in this Figure of description, also do not illustrate.
The beneficial effects of the utility model are: the utility model is to increasing track adjusting wheel 3A between the traction sheave 3 at crosshead sheave 6, make track adjusting wheel 3A vertical with hoist ropes 4 between the crosshead sheave 6, operation up and down along with car 7, the traction cornerite immobilizes, so that the design calculation of the installation of elevator and traction has also solved sideslip and the monolateral problem of leading the boots heel and toe wear.
Because above-mentioned beneficial effect, the utility model is widely used in the 4:1 towed elevator.
Description of drawings
Fig. 1 is the structural representation of prior art traction system;
Fig. 2 is a structural representation of the present utility model.
Identifier declaration: 1-side guide wheel; 2--counterweight wheel; The 3--traction sheave; 3A-track adjusting wheel; 4-hoist ropes; 5--counterweight body; The 6--crosshead sheave; The 7--car.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 2, the traction system design of 4:1 small room cargo lift, comprise side guide wheel 1, counterweight wheel 2, traction sheave 3, track adjusting wheel 3A, hoist ropes 4, counterweight body 5, crosshead sheave 6, car 7, track adjusting wheel 3A between described traction sheave 3 and described crosshead sheave 6, hoist ropes 4 one ends successively via traction sheave 3, track adjusting wheel 3A, crosshead sheave 6, side guide wheel 1 to fixing fag end M; The other end of described hoist ropes 4 successively via traction sheave 3, counterweight wheel 2, side guide wheel 1 to fixing fag end N.
Being similar among Fig. 2 " ground connection " sign be to be fixing fag end, fixedly fag end of 2 places is arranged among the figure, be nominally M and N respectively, owing to being the general setting of elevator, no longer detailed description.
The engine installation of traction system is that non-the present utility model main points do not illustrate among Fig. 2 for permanent-magnet synchnorous gearless dragging machine drives, and also no longer describes in detail.
About the beneficial effects of the utility model and use occasion, substantially ditto state bright, so repeat no more.
