Two pairs of counterweight 5, which return to, has gap between rope sheave 8, the rope sheave center of traction machine 4 is located at counterweight and returns gap between rope sheave 8
Surface.In the present solution, being two to rope sheave 8 is returned to, and it is distributed in carriage and returns 7 two sides of rope sheave, and the length that counterweight 5 is whole
(along the distance in the front-back direction of carriage 3) is bigger, therefore can reduce the width of counterweight 5 and height are corresponding, so that it is right to reduce counterweight 5
Elevator assembles the influence of (3 size of carriage).Meanwhile the structure and rigging position of counterweight 5, it can make full use of effective space,
Lift car 3 is designed into maximization, to realize that elevator is accomplished to maximize by small hoistway 1, and 5 pieces of counterweight use cement block
, cast iron counterweight 5 is not used, so that the cost of elevator is substantially reduced, it is more environmentally friendly more economical.The rope sheave position of the traction machine 4
Above counterweight 5, and the rope sheave returns rope sheave 7 with carriage and is generally aligned in the same plane.In this way, 4 installation site of traction machine is more reasonable, hoistway
1 top layer can be utilized adequately, and when assembly, car top edge is less than 300mm, service personnel to the distance design of 1 inner wall of hoistway
When car top overhauling of standing, the danger that personnel fall from edge will not be generated, elevator components cost is saved.
On spandrel girder 2, it is equipped with 3 rope hitch plate of a carriage and two counterweight rope hitch plates 9, wherein 3 rope hitch plate of carriage is located at
Carriage returns 7 top of rope sheave, and is located at two carriages and returns side of the rope sheave 7 far from counterweight 5；Two counterweight rope hitch plates 9 be located to return to rope
8 top of wheel, and it is located at two pairs of two sides for returning to rope sheave 8.The wirerope 6 is more, one end of more wirerope 6 and sedan-chair
3 rope hitch plate of compartment is fixedly connected, and the other end, which successively bypasses after two carriages return the rope sheave of rope sheave 7 and traction machine 4, is divided into two groups, and respectively
Rope sheave 8 is returned to around two pairs, is finally fixedly connected respectively with two counterweight rope hitch plates 9.The carriage returns the rope of rope sheave 7, traction machine 4
It takes turns and two pairs returns on rope sheave 8, corresponding wirerope 6 is equipped with rope groove；To avoid generating friction, damage between wirerope 6
Deng.When it is implemented, the wirerope 6 arranges the wirerope 6 of odd number from rope sheave one end of traction machine 4 to the other end around same
To rope sheave 8 is returned to, the wirerope 6 of even number is arranged around another pair and returns to rope sheave 8；To make wirerope 6 return to rope sheave 8 to two pairs
Improving stability it is more preferable.
The counterweight 5 further includes 5 frame of counterweight and 5 pieces of counterweight, and 5 pieces of the counterweight is installed in 5 frame of counterweight, the counterweight
The two sides of 5 frames are slidably matched with counter weight guide track to be connected, wherein the distance between two counter weight guide tracks are greater than 3 front and rear sides of carriage
Between distance half.The length of 5 pieces of the counterweight is greater than the half of distance between 3 front and rear sides of carriage, also, the counterweight
5 pieces are cement block.This programme, for the machine-roomless lift of 5 two-wheel top hanging of counterweight driving, weight Two-wheeled, because of traction machine 4
It is mounted on entity counterweight 5, therefore will not empathize, do not need to set damper, in the process of running, wirerope 6 is draging
Draw machine 4 rope sheave grating, gearbox noise substantially reduces；And hoist ropes is the leading block that spandrel girder 2 is pushed up by hoistway 1
(bottom) diversion sheave is pushed up around carriage 3, returns again to the top of hoistway 1, the vibration for traction machine 4, by secondary counter around traction machine 4 shakes
It is dynamic to will not influence carriage 3, meanwhile, noise has been decomposed by two movable pulley windings by 5 hoist ropes of counterweight.
Finally, it should be noted that above embodiments are merely intended for describing the technical solutions of the present application, but not for limiting the present application technology
Scheme, those skilled in the art should understand that, those are modified to the technical solution of the utility model or are equal
Replacement, without departing from the objective and range of the technical program, should all cover in the scope of the claims of the utility model.
