Counterweight post-positioned elevator without machine room

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 [0001] The invention relates to the field of elevators, in particular to a machine room-less elevator with a rear counterweight. Background technique [0002] The counterweight of traditional machine room-less elevators is generally set on the side of the car, while the counterweight of traditional machine room elevators is generally set on the rear side of the car. At present, in order to improve the utilization space of buildings, many owners often place the elevator originally planned as a machine room Changed to an elevator without a machine room, and due to the structural layout of an ordinary elevator without a machine room, the required elevator shaft is wider than that of an elevator with a machine room when the size of the car is the same. The width of the car, otherwise it cannot be installed, which reduces the accommodation space of the elevator. Contents of the invention [0003] The technical problem to be solved by the present invention is to...
