Problems solved by technology

This kind of traction elevator adopts a load-bearing beam composed of two symmetrically arranged I-beams horizontally arranged above the ground of the machine room, and a horizontally set on the ground of the machine room and perpendicular to the load-bearing beam. The counterweight beam is jointly used as the beam carrying the counterweight and the car. This structure needs to be welded at the junction of the load-bearing beam and the counterweight beam, which is not stable enough and makes the operation of realizing the technical solution more complicated; when The counterweight moves too fast and may swing towards the car when passing by the car, which will increase the force on the wire rope, which will bring some safety hazards

Embodiment 1

[0032] 1. A traction elevator, comprising:

[0033] The shaft 1 provides installation locations for the elevator lifting component 2, the counterweight lifting component 3 and the power component 4;

[0034] The elevator lifting assembly 2 is installed in the shaft 1 and moves up and down under the action of the power assembly 4;

[0035] The counterweight lifting assembly 3 is installed in the hoistway 1, and the gravity of the elevator lifting assembly 2 is balanced by a steel wire rope 43;

[0036] The power assembly 4 is installed in the hoistway 1 to provide lifting power for the elevator lifting assembly 2;

[0037] Described shaft 1 comprises:

[0038] The elevator shaft 11 provides space for the elevator box 21 to move up and down;

[0039] The counterweight shaft 12 provides space for the counterweight 31 to move up and down;

[0040] The load-bearing beam 13 is composed of a first profile 131 and a second profile 132 arranged in parallel, and is fixedly installed...

Abstract

A traction type elevator comprises a hoistway, an elevator lifting assembly, a counterweight lifting assembly and a power assembly. According to the traction type elevator, only two pieces of structural steel are used as bearing beams of the elevator, so that the number of reserved bearing platforms is reduced, the construction difficulty is reduced, and the cost is saved; and meanwhile, a support partition plate is further arranged between a counterweight and an elevator car, and support is provided for an elevator car guide device. Counterweight wheels arranged on the counterweight side by side in a staggered mode and rotatable counterweight guide wheels arranged on the bearing beams enable a steel wire rope to be freely and vertically stressed, the counterweight wheels are located between the horizontal projections of the two bearing beams, it is guaranteed that the steel wire rope is evenly stressed, the influence of possible slight twisting of the counterweight on the steel wire rope is avoided, and reliable and long-term operation of the elevator is guaranteed.

Description

technical field [0001] The invention relates to the field of elevators, in particular to a traction elevator. [0002] technical background [0003] An elevator is a vertical lift powered by an electric motor, equipped with a box-shaped gondola, used for multi-storey buildings to take people or carry goods. A vertical lift has a car that runs between at least two vertical columns of steel guide rails. The size and structure of the car are convenient for passengers to enter and exit or to load and unload goods. The emergence of elevators not only facilitates people's up and down stairs, but also greatly promotes the development of real estate in the direction of super high-rise buildings. [0004] The Chinese patent with the application number CN201721884399.X discloses a traction structure for a machine room traction type car elevator, including: a load-bearing beam composed of two symmetrically arranged I-beams horizontally arranged above the ground of the machine room, an...
