Embodiment Construction

[0024] 1. The installation of the car traction rope: a certain number of steel wire ropes are installed vertically at the upper and lower ends of the elevator shaft to guide the elevator car or counterweight to run, to replace the current assembled elevator track. The elevator traction ropes are installed vertically at the four corners of the car, or hoisted in the form of a hoisting surface (the apex of a triangle or polygon is used as a number of hoisting points to form a hoisting surface), which can effectively prevent the elevator from being damaged due to uneven load distribution. is crooked.

[0025] 2. The method of running multiple elevators on the same guide rail: choose a suitable hoisting position, keep a certain distance between the traction ropes of multiple elevators, and realize partitioning or simultaneous up and down on the same guide rail under the intelligent control of the computer running.

[0026] 3. Installation method of the hall door: adopt the card i...

Abstract

The invention provides a brand-new elevator aiming at the situations of high manufacturing cost, high civil engineering construction cost, high installation risk and the like of the conventional elevator. An elevator operation guide device is vertically hung at the upper end of an elevator shaft or a machine room and is used for guiding an elevator cage or a counterpoise to operate; and elevator hoisting ropes are respectively arranged at the positions of four corners of the cage vertically or are hoisted in the form of a hoisting surface. A hoistway door adopts a clamping way; wires of a control cabinet are integrated into a circuit board; a safety fence of a switch is arranged above a cage door machine; pr-buried foundation bolts are arranged at the corresponding positions of the wall of the elevator shaft; a guide rail can be directly arranged on the bolts; a blocking rope is arranged at the lower end or the upper end of the elevator shaft so that the elevator is retarded in a forced way; and an acousto-optic alarm device for an elevator maintenance state is arranged. By the elevator provided by the invention, the manufacturing cost, the civil engineering construction cost and construction accident risks can be greatly reduced; and a plurality of elevators can be operated on the same guide rail.

Description

technical field [0001] This patent relates to elevators. Background technique [0002] The installation situation of the existing elevator is: [0003] 1. During the civil construction of the elevator shaft, lay embedded iron or poured concrete ring beams on the shaft wall every 2 meters. [0004] 2. When installing the elevator guide rails, first set up scaffolding in the shaft. [0005] 3. Weld guide rail brackets on all pre-embedded iron or concrete ring beams. [0006] 4. Hoist the heavy elevator guide rails to each guide rail bracket section by section from bottom to top. [0007] 5. The verticality and parallelism of each section are finely adjusted. [0008] 6. The hall door is fixed by punching holes in the wall with screws. [0009] 7. In order to increase the driving capacity of the traction machine, the traction rack has to be raised to increase the wrapping angle of the wire rope on the traction wheel, resulting in the height of the machine room being too hi...
