Abstract
The invention relates to a counterweight post-positioned elevator without a machine room, which comprises a well channel, a cage, a diversion sheave, a tractor and a counterweight diversion sheave, wherein the cage is arranged in the well channel; two spandrel girders are arranged in the well channel; a counterweight rope head plate is arranged on one side of one of the spandrel girders; two guiding wheels are arranged on the other spandrel girder; an axle bottom wheel is arranged at the bottom of the cage; one end of a steel wire rope is fixedly connected with the counterweight rope head plate; the steel wire rope downward passes by the axle bottom wheel, then upward passes by the two guiding wheels, downward extends, and then is matched with the diversion sheave, the tractor and the counterweight diversion sheave, so as to fix the tail end of the steel wire rope on the spandrel girders; and a counterweight block is arranged on the steel wire rope. The counterweight post-positioned elevator without the machine room is suitable for transforming the elevator with the machine room into the elevator without the machine room.
Description
Technical field
The present invention relates to the elevator field, refer to especially a kind of machine-roomless lift of counterweight postposition.
Background technology
Traditional machine-roomless lift counterweight operated by rotary motion is in the car side, and traditional machine room elevator counterweight operated by rotary motion is arranged at the car rear side, at present, a lot of owners are in order to improve the space that utilizes of building, usually originally planning as there to be the elevator of machine room to change machine-roomless lift into, and common machine-roomless lift is owing to the structural arrangement reason, in the identical situation of car size, the elevator hoistways ratio that needs has machine room elevator wide, car width certainly will to be reduced so will there be machine room elevator to change machine-roomless lift into, otherwise can't install, this is just so that the minimizing of the spatial accommodation of elevator.
Summary of the invention
Technical matters to be solved by this invention is: a kind of machine-roomless lift that does not affect the counterweight postposition of elevator spatial accommodation is provided.
For addressing the above problem, the technical solution used in the present invention is: a kind of machine-roomless lift of counterweight postposition, comprise hoistway, be arranged on car, diversion sheave, towing machine and counterweight diversion sheave in the hoistway, be provided with two bearing beams in the hoistway, bearing beam one side is provided with the counterweight rope hitch plate, is provided with two track adjusting wheels on another root bearing beam; The car bottom is provided with the sedan-chair return pulley, it is characterized in that: an end that is fixedly connected with steel rope on the described counterweight rope hitch plate, steel rope downwards through the sedan-chair return pulley upwards, downward through two track adjusting wheels again, then by with the cooperatively interacting of diversion sheave, towing machine and counterweight diversion sheave, the end of steel rope is fixed on the bearing beam, is provided with pouring weight on the steel rope.
As a kind of preferred version, after described steel rope is downward through two track adjusting wheels, make progress through diversion sheave, it is downward to pass through towing machine again, finally by crossing counterweight diversion sheave upwards.
As a kind of preferred version, described towing machine is oppositely installed, described steel rope through two track adjusting wheels downwards after, through the towing machine oppositely installed upwards, it is downward to pass through diversion sheave again, finally by crossing counterweight diversion sheave upwards.
As a kind of preferred version, described car bottom is provided with the sedan-chair return pulley on four angles, and steel rope makes progress through two sedan-chair return pulleys of homonymy.
The invention has the beneficial effects as follows: the machine-roomless lift of above-mentioned a kind of counterweight postposition, by changing the position of counterweight, can realize the machine room access and the exchange of machine room hoistway is arranged, and not affect the width of car that it is convenient that installation is transformed, and saves cost.

Fig. 2 is the counterweight arrangement figure of the machine-roomless lift of a kind of counterweight postposition of the present invention.
Among Fig. 1 and Fig. 2: 1, hoistway, 2, car, 3, diversion sheave, 4, towing machine, 5, counterweight diversion sheave, 6, bearing beam, 7, the counterweight rope hitch plate, 8, track adjusting wheel, 9, the sedan-chair return pulley, 10, steel wire, 11, to pouring weight.
The specific embodiment
Be described in further detail below by the machine-roomless lift of specific embodiment to a kind of counterweight postposition of the present invention.
As depicted in figs. 1 and 2, a kind of machine-roomless lift of counterweight postposition, comprise hoistway 1, be arranged on car 2, diversion sheave 3, towing machine 4 and counterweight diversion sheave 5 in the hoistway 1, be provided with two bearing beams 6 in the hoistway 1, bearing beam 6 one sides are provided with counterweight rope hitch plate 7, are provided with two track adjusting wheels 8 on another root bearing beam 6; Car 2 bottoms are provided with sedan-chair return pulley 9, be fixedly connected with an end of steel rope 10 on the described counterweight rope hitch plate 7, steel rope 10 makes progress through sedan-chair return pulley 9 at the bottom of extending to sedan-chair, again through two track adjusting wheels 8, steel rope 10 is directed to rear side, in the present embodiment, steel rope 10 successively through diversion sheave 3 upwards, towing machine 4 downwards and counterweight diversion sheave 5 backward on, the end of steel rope 10 is fixed on the bearing beam 6, is provided with pouring weight 11 on the steel rope 10.Certainly, steel rope 10 also can be fixed on the bearing beam by other means, for example, towing machine 4 is oppositely installed, after steel rope 10 was directed to rear side through two track adjusting wheels 8, through towing machine 4 upwards, it was downward to pass through diversion sheave 3 again first, on backward finally by counterweight diversion sheave 5, the steel rope end is fixed on the bearing beam 6.
Described car 2 bottoms are provided with sedan-chair return pulley 9 on four angles, and steel rope 10 makes progress through two sedan-chair return pulleys 9 of homonymy, can make car 2 front sides or rear side, also can adjust according to different hoistways 1 and arrange.Described towing machine 4 parts can stretch in rear side hoistway 1 wall, to save hoistway 1 space.
The machine-roomless lift of above-mentioned a kind of counterweight postposition by changing the position of counterweight, can be realized machine room access and the exchange that machine room hoistway 1 is arranged, and do not affect the width of car 2, it is convenient that transformation is installed, and also can adopt concrete for making to pouring weight 11, saves cost.
The above embodiments are principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not is used for restriction the present invention; Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the invention design, can also make some distortion and improvement, these all belong to protection scope of the present invention.
