Problems solved by technology

[0004] However, in the current construction without scaffolding, since the construction in the shaft can only be carried out sequentially from bottom to top, the construction period is difficult to shorten, especially for the elevators of super high-rise buildings, the construction period is longer, and the mobile platform in the shaft needs to consume more energy. electricity

Embodiment 1

[0035] Such as Figure 1-3 As shown, a double-platform scaffold-free elevator installation method is characterized in that the installation procedure is: making samples and setting out wires—installation of machine room equipment—temporary platform erection—bottom pit equipment installation—car platform assembly— Installation of moving down platform—installation of traction type and speed limiter—slow train debugging—use of platform construction—removal of platform and installation of counterweight—car hardcover—fast train commissioning, details are as follows:

[0036] Make the model and set out the wire: make the model frame according to the actual relevant dimensions of the elevator car, counterweight, guide rail and other components, install the model frame in the machine room, then hang the plumb line according to the model frame, and stabilize the plumb line;

[0037] Machine room equipment installation: install traction machine, speed limiter and control cabinet in the ...

Embodiment 2

[0049] A project includes the installation of 4 high-speed elevators, the length of the elevator shaft is 70m, and the maximum operating speed of the elevator is 6m / s. The contract elevator construction period for elevator installation is 60 days. Since the construction progress of the civil works is 18 days later than planned, the actual construction period of the elevator is only 42 days. The traditional scaffolding elevator installation method has been unable to complete the elevator installation task within the specified construction period. Therefore, The technicians conducted several studies and discussions on the plan, and formulated a double-platform elevator installation method:

[0050] The elevator installation procedure used is: making prototypes and laying out wires—machine room equipment installation—temporary platform erection—pit equipment installation—car platform assembly—downward platform installation—traction and speed governor installation ——Slow train debug...

Abstract

The invention discloses a double-platform scaffold-free elevator installation method. The method is characterized by comprising the installation procedures of manufacturing a template and unwinding a wire, installing machine room equipment, erecting a temporary platform, installing bottom pit equipment, assembling a lift car platform, assembling a downward moving platform, installing a traction speed limiter, performing slow operation regulation, utilizing the platforms to construct, disassembling the platforms and installing counterweights, fine decorating a lift car and performing quick operation regulation. The double-platform scaffold-free elevator installation method is short in installation period, low in construction power consumption and suitable for installation of high-rise elevators.

Description

technical field [0001] The patent of the invention belongs to the field of elevator construction methods, and in particular relates to a construction method for elevator installation in high-rise buildings. Background technique [0002] With the continuous development of the modern construction industry, the scale of elevator projects is getting larger and larger, and the lifting height is getting higher and higher, which puts forward higher requirements for elevator installation. The traditional elevator installation method needs to install scaffolding in the elevator shaft, especially for high-rise buildings. The construction of scaffolding not only requires a large amount of engineering, but also requires a lot of manpower, material resources and time for the transportation, installation, disassembly and storage of the scaffolding, which affects the construction. Cycle and cost control. [0003] Scaffoldless construction is a new type of elevator installation technology,...
