Abstract
The invention discloses an elevator traction device. The elevator traction device comprises an elevator compartment, a bottom pit and a shaftway, and is characterized in that the bottom pit is provided with a guide wheel and a traction machine, the top end of the shaftway is provided with two fixed pulleys, the guide wheel is connected with the traction machine through a chain, and the two fixed pulleys are connected with each other through a chain; in the vertical direction of the shaftway, the upper end and the lower end of the elevator compartment are respectively connected to the fixed pulleys and the guide wheel through a steel wire rope. The elevator traction device is unnecessary for utilizing an elevator balancing chain, so that the running stability of the elevator is improved, the safety performance is improved, the elevator is convenient to install and repair, the cost is saved, and the service life of the elevator can be effectively prolonged.
Description
Technical field
The invention belongs to elevator technology field, be specifically related to a kind of elevator drag device.
Background technology
Existing elevator drag device, generally need to use elevator balanced chain, weight for balance hoist ropes, to elevator, the effect of balance and compensation is played in operation, but in elevator real process, balancing chain easily swings up and down time, thereby elevator is shaken, cause potential safety hazard, but also can produce ear-piercing noise.
Summary of the invention
The object of this invention is to provide a kind ofly can overcome above-mentioned defect, without the elevator drag device that uses elevator balanced chain.
For achieving the above object, the present invention has adopted following technical scheme:
An elevator drag device, comprises lift car, pit and hoistway, it is characterized in that, at pit, track adjusting wheel and towing machine is set, and two fixed pulleys are set on hoistway top, between described track adjusting wheel and towing machine, connect by chain between two fixed pulleys; In the vertical direction of hoistway, the top and bottom of lift car are connected in fixed pulley and track adjusting wheel by steel rope respectively.
As one of preferred version, in hoistway, be also provided with moving up and downly to pouring weight, described the top and bottom of pouring weight are connected in to fixed pulley and track adjusting wheel by steel rope respectively.
As one of preferred version, described fixed pulley, pouring weight, lift car and track adjusting wheel are formed to loop configuration by described steel rope.
Invention advantage:
Elevator drag device tool of the present invention has the following advantages: elevator drag device of the present invention is without using elevator balanced chain, improve the stability of whole elevator operation, improve safety performance, and when installation and maintenance lift more for convenience, cost-saving, effectively improve elevator service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of elevator drag device of the present invention;
Wherein, 1, lift car, 2, fixed pulley, 3, to pouring weight, 4, track adjusting wheel, 5, towing machine, 6, steel rope, 7, chain.
The specific embodiment
Below in conjunction with accompanying drawing and a preferred embodiment, technical scheme of the present invention is further described.
Embodiment:
As shown in Figure 1: a kind of elevator drag device that the present embodiment discloses, comprise lift car 1, pit and hoistway, it is characterized in that, at pit, track adjusting wheel 4 and towing machine 5 are set, two fixed pulleys 2 are set, between described track adjusting wheel 4 and towing machine 5, connect by chain 7 between two fixed pulleys 2 on hoistway top; In the vertical direction of hoistway, the top and bottom of lift car 1 are connected in fixed pulley 2 and track adjusting wheel 4 by steel rope 6 respectively.
As one of preferred version, in hoistway, be also provided with moving up and downly to pouring weight 3, described the top and bottom of pouring weight 3 are connected in to fixed pulley 2 and track adjusting wheel 4 by steel rope 6 respectively.
As one of preferred version, described fixed pulley 2, pouring weight 3, lift car 1 and track adjusting wheel 4 are formed to loop configuration by described steel rope 6.
Elevator drag device of the present invention, without using elevator balanced chain, improves the stability of whole elevator operation, improves safety performance, and when installation and maintenance lift more for convenience, cost-saving, effectively improve elevator service life.
It is to be noted; as described above is only in order to explain the present invention's preferred embodiment; not attempt is done any formal restriction to the present invention according to this; be with; all any modification or changes that has the relevant the present invention that does under identical invention spirit, all must be included in the category that the invention is intended to protection
