Abstract
The invention provides a rear-counterweight villa elevator device without a machine room. The device comprises a car, a tractor, a traction rope, a counterweight body, a counterweight diversion sheave and two bottom diversion sheaves; the tractor is fixed on the top part of an elevator shaft; the counterweight diversion sheave is connected with the counterweight body to form an elevator counterweight unit which is positioned at the rear side of the car; a traction wheel is directly connected with the counterweight diversion sheave through the traction rope; the bottom diversion sheaves are fixed to the bottom part of the car and are respectively close to the front and back diagonal angles at the bottom of the car; an included angle is formed between a connecting line of the two bottom diversion sheaves and a central line of the car; the two bottom diversion sheaves are connected with the traction wheel through the traction rope. The device has the beneficial effects that the width of the elevator car can be ensured in case of insufficient elevator shaft width, and thus the comfort of using can be avoided being influenced by excessively small car width.
Description
Technical field
The present invention relates to counterweight villa ladder device after a kind of machine room.
Background technology
In existing technology, the feature of villa ladder is counterweight side, and counterweight is arranged on the side of car, like this when the shaft width that elevator is installed is not enough, the space width of cab interior will be made narrow, comfort level when taking is reduced greatly.
Summary of the invention
The problem to be solved in the present invention is to provide counterweight villa ladder device after a kind of machine room, and counterweight unit is placed on rear side of car by this device, takes full advantage of limited hoistway space, makes cab interior space more spacious and comfortful.
For solving the problems of the technologies described above, the technical solution used in the present invention is: counterweight villa ladder device after machine room, and comprise diversion sheave at the bottom of car, towing machine, hoist ropes, pair weight, counterweight diversion sheave and two sedan-chairs, described towing machine is fixed on elevator hoistways top;
Described counterweight diversion sheave is connected with described pair weight, and both form Elevator weight sensor unit jointly, and described counterweight unit is placed on rear side of described car; Described traction sheave is directly connected by described hoist ropes with described counterweight diversion sheave;
At the bottom of described sedan-chair, diversion sheave is fixed on described cage bottom, diversion sheave at the bottom of two described sedan-chairs lays respectively near the diagonal angle, front and back at the bottom of described sedan-chair, the line of diversion sheave at the bottom of two described sedan-chairs and the line of centers of described car have angle, and at the bottom of two described sedan-chairs, diversion sheave is connected by described hoist ropes with described traction sheave;
Described hoist ropes is perpendicular to the ground.
Further, also comprise diversion sheave beam at the bottom of sedan-chair, diversion sheave at the bottom of two described sedan-chairs is fixed on diversion sheave beam two ends at the bottom of described sedan-chair.
The advantage that the present invention has and good effect are: when shaft width is not enough, utilizes at the bottom of the sedan-chair of wide-angle and return rope sheave, making towing machine be in the rear side of car, directly being connected returning to rope sheave by traction sheave.Counterweight is arranged on rear side of car, makes car can maximum using shaft width.
Accompanying drawing explanation
Fig. 1 is plan structure schematic diagram of the present invention;
In figure: 1 is counterweight fag end; 2 is counterweight diversion sheave; 3 is pair weight; 4 is towing machine; 5 is counter weight guide track; 6 is traction sheave; 7 for returning rope sheave at the bottom of sedan-chair; 8 is car guide rail; 9 for returning rope sheave beam at the bottom of sedan-chair; 10 is velocity limiter; 11 is car.
Detailed description of the invention
As shown in Figure 1, the invention provides counterweight villa ladder device after a kind of machine room, comprise diversion sheave 7 at the bottom of car 11, towing machine 4, hoist ropes, pair weight 3, counterweight diversion sheave 2 and two sedan-chairs, towing machine 4 is fixed on elevator hoistways top, towing machine 4 has traction sheave 6; Counterweight diversion sheave 2 is connected with pair weight 3, and both form Elevator weight sensor unit jointly, and counterweight unit is placed on rear side of car 11; Traction sheave 6 is directly connected by hoist ropes with counterweight diversion sheave 2;
Diversion sheave 7 at the bottom of sedan-chair is fixed on bottom car 11, and diversion sheave 7 at the bottom of two sedan-chairs lays respectively near the diagonal angle, front and back at the bottom of sedan-chair, and the line of diversion sheave 7 at the bottom of two sedan-chairs and the line of centers of car 11 have angle, and at the bottom of two sedan-chairs, diversion sheave 7 is connected by hoist ropes with traction sheave 6;
Described hoist ropes is perpendicular to the ground.
At the bottom of two sedan-chairs, diversion sheave is fixed on bottom car 11 by diversion sheave beam 9 at the bottom of a sedan-chair.
As can be seen from said structure, the counterweight unit of device is placed in the space greatly can saving hoistway both sides on rear side of car 11, simultaneously due to the size of villa ladder itself and weight less, make the line of diversion sheave 7 at the bottom of two sedan-chairs can wide-angle tilt, thus traction sheave directly can be connected with diversion sheave 7 at the bottom of counterweight diversion sheave 2 and sedan-chair, without the need to increasing track adjusting wheel, which offers a saving the installation of gantry top bearing beam, further having saved hoistway overhead.
Above one embodiment of the present of invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
