Method and advantages of no scaffold installation for elevator

Lift installation is part of the customer service service elevator, elevator lift connecting plate mounted homing is a reduction to improve installation quality and increase the new elevator construction safety cost and installation method. The elevator lift connecting plate installation method adopts car bottom of the elevator as the floor construction basket; to guide its operation as a guide rail lift basket in the hoistway; to lift its host as power basket in the hoistway of ascension; to lift its limit, limit, and buffer switch governor, and safety safety components as safety components, nacelle construction in the hoistway. The use of the frame tube is reduced to a maximum extent. Method for correcting guide rail by using more advanced side sample line and side line correcting ruler.


With the elevator market competition is increasingly fierce, elevator factory in elevator installation is also considering to reduce costs, improve efficiency, now, most of the elevator factory has agreed to during the installation of the elevator installation slow moving, which gives the elevator self guided mounting provides a prerequisite for.

Process characteristics:

Lift installation for homing mainly use the elevator door system itself and the host car elevator installation work, and during the installation process without the aid of other means of transport and transport.

The elevator homing installation method has the following advantages:

Simple and easy to implement

Because the installation method were used to lift their parts, just change the elevator general program installation, and lift installation method compared with general did not increase the installation of the new volume, so it is different from the general elevator installation way of the hanging basket.

Two. Reduce the elevator installation project cost

With a self guided installation method than with usual elevator installation method of a lift cost savings of more than 8000 yuan. The installation cost of a lift is usually about 20000 yuan. This will be described in the future benefit analysis.

Three. Improve construction efficiency

Because the elevator installation and use of electric drive in homing type elevator installation in the elevator installation completed most of the work, it saves time and labor handling elevator accessories, can greatly improve the efficiency of construction elevator installation.

Lift installation homing method reduces the use of small, more emphasis on personal installation capacity of the installation workers, technical direction so the method will guide the installation of the elevator installation enterprises from labor-intensive to the development of the elevator.

Four. Improved security

1 lift installation method of the self guided model frame is usually set up at the top of the chute to set up in the room. Because the building is erected on the floor of the machine room, the upper model frame is avoided at the top of the well path;

2 general elevator, the installation of the shaft components (such as guide rails, rails, hall door, etc.) when the elevator installation workers are standing on the scaffolding installed, the greater the risk. The elevator installation method in installation of self guided hoistway parts installation workers is standing on the installation of safety protection elevator car full body, to protect the safety of the elevator car:

In the car, the erection of the scaffolding and the corresponding increase in the rail, in order to ensure that the elevator in the running process of the car outside the object of the installation of workers hurt;

In the whole installation process, the safety clamp and the speed limiter for speeding protection;

In the whole installation process, the lower position, the car buffer and the electric protection function of the limit operation position of the heavy buffer switch;

4. During the whole installation, car buffer and counterweight buffer limit position buffer;

Scope of application

Lift homing type installation method is applicable to all ladder installation, lift the number of stations is high, its advantages more prominent.

Process flow and operation points of the installation of the elevator without scaffold

One. Construction process

1 preparation work

1. In the process of the construction of the elevator hoistway, and the top floor in the same elevation on the wall and across the doorway or around the wall each reserved two holes whose diameter is larger than 60, without reservation in construction, can be dug themselves in elevator construction; the reserved hole erection platform the assembly of heavy frame;

2. If well after the wall gable or not in well after the opening of the wall, the pipe rack from the hoistway hoistway outward erection pick platform, the specific practices such as map:

The elevator shaft is brick structure, both ends of the bar in the concrete beam column must rely on.

Connection between frame tube with straight button and universal joint.

At the end of the pit to take a 4 - meter - high - floor, to install the bottom of the guide rail.

2 set up the model frame

Lift homing mounted in the engine room floor is fixed on the frame model.

1. Well will lead to the edge of the room;

2. Play the two hole hammer in the room floor on the approximate position of hall sample points, at the same time in the hall like setting out line;

Measurement of the data in each layer, and finally determine the location of the sample point on the sample shelf according to the data of the well;

4. According to the position of the fixed door like a whole frame model, and the line from the room into the bottomless pit;

The special method of the guide rail sample line is different from the conventional line and the special ruler:

Practice is just in front of the working face away from the rail rail 10mm ~ 30mm place like line, elevator guide rail type installation in homing line in the guide rail side work surface from 150mm to 200mm, the specific figure:

Self guided installation line on both sides of the guide rail laying line, must be with the school track special ruler figure:

The school ruler is suitable for the installation of all straight ladders.

The fixed frame model.

3 work in the computer room: host, speed governor, control cabinet in place; laying machine room line slot and application lines, wiring; terminal on the control cabinet line short circuit; host insulation test; no-load test.

4 slow start:

Installation of a guide rail bracket on a well frame of the bottom hole, and a first guide rail is installed and corrected;

Installation of car and the weight of the buffer;

Assembling cage frame, safety clamp and bottom plate, guide shoe;

4. Derrick demolition pit;

5. On top of the hand pulling hoist hanging on the heavy frame;

The steel wire rope.
