Abstract
The utility model relates to a machine-room-free elevator with a rear-mounted counterweight. The machine-room-free elevator with the postpositional counterweight comprises a hoistway, a cage arranged in the hoistway, a diversion sheave, a traction machine and a counterweight diversion sheave. Two bearing beams are arranged in the hoistway, a counterweight rope hitch plate is arranged on one side of one bearing beam, and two guiding wheels are arranged on the other bearing beam. Cage bottom wheels are arranged on the bottom portion of the cage, one end of a steel wire rope is fixedly connected on the counterweight rope hitch plate, the steel wire rope extends downwards, passes through the cage bottom wheels, extends upwards, and then extends downwards through the two guiding wheels, the tail end of the steel wire rope is enabled to be fixed on one bearing beam through the matching of the diversion sheave, the traction machine and the counterweight diversion sheave, and a counterweight a arranged on the steel wire rope. The machine-room-free elevator with the postpositional counterweight is suitable for transforming an elevator with a machine room into an elevator without the machine room.
Description
Technical field
The utility model relates to the elevator field, refers to a kind of machine-roomless lift of counterweight postposition especially.
Background technology
Traditional machine-roomless lift counterweight operated by rotary motion is in the car side, and traditional organic machine room-free elevator counterweight operated by rotary motion is at the car rear side, at present, a lot of owners are in order to improve the space that utilizes of building, usually planning to there to be the elevator of machine room to change machine-roomless lift into originally, and common machine-roomless lift is owing to the structural arrangement reason, under the identical situation of car size, the elevator hoistways that needs is wideer than organic machine room-free elevator, car width certainly will to be reduced so change organic machine room-free elevator into machine-roomless lift, otherwise can't install, this just makes the spatial accommodation of elevator reduce.
The utility model content
Technical problem to be solved in the utility model is: a kind of machine-roomless lift that does not influence the counterweight postposition of elevator spatial accommodation is provided.
For addressing the above problem, the technical solution adopted in the utility model 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, and another root bearing beam is provided with two track adjusting wheels; 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, and steel rope is provided with pouring weight.
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 the 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 the 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 beneficial effects of the utility model are: the machine-roomless lift of above-mentioned a kind of counterweight postposition, by changing the position of counterweight, the exchange that can realize not having the machine room access He the machine room hoistway is arranged, and do not influence the width of car, install transform convenient, the saving cost.
Description of drawings
Fig. 1 is the hoistway plane of arrangement figure of the machine-roomless lift of a kind of counterweight postposition described in the utility model.
Fig. 2 is the counterweight arrangement figure of the machine-roomless lift of a kind of counterweight postposition described in the utility model.
Among Fig. 1 and Fig. 2: 1, hoistway, 2, car, 3, diversion sheave, 4, towing machine, 5, the 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 utility model.
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, and another root bearing beam 6 is provided with two track adjusting wheels 8; 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 backs upwards, the end of steel rope 10 is fixed on the bearing beam 6, and steel rope 10 is provided with pouring weight 11.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 more earlier, finally by counterweight diversion sheave 5 backs upwards, 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 is by changing the position of counterweight, the exchange that can realize not having the machine room access He machine room hoistway 1 is arranged, and do not influence 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 utility model; Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
