Problems solved by technology

[0003] In addition, the traction sheave 1 is arranged perpendicular to the counterweight reversing sheave 2, which requires that there must be a space in the width direction of the cross section of the hoistway that can accommodate the width of the traction machine, so the requirement for the width of the hoistway is also relatively high, which is obviously Will increase the well land use cost

Abstract

The invention discloses a 4: 1 counterweight side middle machine room-less elevator. The 4: 1 counterweight side middle machine room-less elevator comprises a lift car arranged in a shaft, a counterweight and a traction system which is connected with the lift car and the counterweight, the counterweight is arranged on the front side of the lift car; the traction system comprises a traction wheel,a counterweight diversion sheave, car bottom diversion sheaves, a car side top diversion sheave and a counterweight side top diversion sheave; the counterweight diversion sheave is arranged at the topof the counterweight, an acute included angle is formed between the axis of the counterweight diversion sheave and the side wall line of the shaft; the plurality of car bottom diversion sheaves are located at the front end and the rear end of the bottom of the lift car separately, the axas of the car bottom diversion sheaves are parallel to the side wall of the shaft; the counterweight side top diversion sheave and the lift car side top diversion sheave are arranged on the left side and the right side of the lift car respectively; and the axis of the counterweight side top diversion sheave and the axis of the car side top diversion sheave are both perpendicular to the side wall of the shaft. According to the 4: 1 counterweight side middle machine room-less elevator, the elevator shaft utilization rate is increased, and the requirement of an elevator for the shaft plane size is reduced.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a 4-to-1 pair of heavy-side center-mounted machine-roomless elevators. Background technique [0002] Such as image 3 As shown, a disclosed technical solution of a machine room-less elevator with a traction ratio of 4 to 1, specifically includes a traction sheave 1, a counterweight reversing sheave 2, a car bottom reversing sheave 3, a car 4, and a traction rope 5 , Counterweight side top reversing sheave 601, car side top reversing sheave 602, hoistway 7, counterweight 8, counterweight side rope end plate 901, car side rope end plate 902, car bottom wheel 3 is located in car 4 The bottom is close to the center of the car, the axis of the counterweight anti-sheave 2 is perpendicular to the side wall of the hoistway 7, the rope end plate 901 on the counterweight side is located at the side of the traction sheave 1, and the rope end plate 902 on the car side is located in front o...
