Embodiment 1

[0035] like Figure 1-3 As shown in the figure, a method for installing a double platform elevator without scaffolding is characterized in that the installation procedure is: making a template and setting out the line--machine room equipment installation--temporary platform erection--pit equipment installation--car platform assembly-- Down-moving platform installation - traction type and speed limiter installation - slow train debugging - using platform construction - platform removal and installation of counterweight - car hardcover - express train debugging, as follows:

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

[0037] Equipment installation in the machine room: install traction machines, speed limiters, and control cabinets...

Embodiment 2

[0049] A project includes the installation of 4 high-speed elevators, the length of the elevator shaft is 70m, and the maximum running speed of the elevator is 6m / s. The contract elevator construction period for elevator installation is 60 days. Since the civil construction progress is 18 days later than planned, the actual construction period for the elevator installation is only 42 days. The traditional scaffolding elevator installation method cannot complete the elevator installation task within the specified construction period. The technicians conducted many researches and discussions on the plan, and formulated a double platform elevator installation method:

[0050] The elevator installation procedures adopted are: making templates and laying out lines - machine room equipment installation - temporary platform erection - pit equipment installation - car platform assembly - lower platform installation - traction type and speed governor installation ——Slow car debugging——Ut...

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 present invention belongs to the field of elevator construction methods, and specifically 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 bigger and bigger, and the lifting height is getting higher and higher, which puts forward higher requirements for elevator installation. The traditional elevator installation method requires the installation of scaffolding in the elevator shaft, especially for high-rise buildings. The erection of scaffolding not only requires a large amount of work, but also consumes a lot of manpower, material resources and time for the transportation, installation, dismantling and storage of the scaffolding, which affects the construction. Cycle and cost control. [0003] Scaffoldless construction is a new type of elevator installation tec...
