1)Light technical parameters

Scope:
Elevator installation Application:
1. hanging instead of the traditional hammer discharge line
process, directly determine the reference line with Article install
JZC, and measure the hoistway.
2.Opair of guide rails for accurate measurement after installation,
vertical rails determination linearity deviations, the measured
data is used to draw the rails in the X, Y coordinate axis of the
curve, and analysis of two primary rail in space X, Y two parallel
bias.
3.use JZC laser level scanning function, the threshold level of
elevators and other components were crossed and measurement.
Elevator installation quality acceptance Application:
Rapid Determination of the vertical rail mounting, parallelism, and
bias in the space X, Y axis for the elevator ride quality merits of
a scientific analysis of the data provided.
Elevator maintenance transformation application:
Since the online operation of the elevator guide rails are many
causes of vertical, linear guide, etc. changes. Use JZC can always
measure the linear guide occurs, parallelism deviations. And so
decide whether to amend the data. Therefore, when the elevator
renovation, use JZC allows you quick and easy replacement,
correction rail.
Application of escalators and moving walkways installation (need to
increase the Annex - horizontal scan converter):
1.escalator installation to determine the level of reference
2.determine and detect moving walkway installation level
benchmarks.
3. automatic lifting parking equipment installation and testing to
determine the level of the baseline.
Applications:
Applicable to other needs precision vertical and horizontal datum
reference measurement occasions
Elevator guide rail installation, testing existing problems
Ride quality factors affecting rail mounting lift
Plumb sex
After the completion of the building due to various factors, will
produce uneven settlement, the building will tilt to one direction,
then the guide also followed the building and lean, the car guide
shoe will be pressed against the T-rail of a working surface, The
size of this force, if the calculation of the total weight of
2000kg press the elevator is full, then the guide verticality
deviation 1 °, will produce 35 kg of lateral force, and this is a
continuous load, it will increase the wear on the shoes, so
mounting rails are in a vertical line to do benchmarks.
Linearity
In rail mounting process will appear linear bias. The existence of
this bias makes the elevator car acceleration is generated in the
operation level, once the deviation is large enough, it will affect
the ride comfort, serious hoistway information collection will
generate an error signal, which will affect the safe operation of
the lift .
Rail linear deviation along X, Y-axis direction both positive and
negative deviations.
National Elevator installation and acceptance criteria for rail
mounting make strict rules, "GB50310-2002" provides that "the two
columns from the deviation between the top surface of the rail
should be: the car guide rails 0 ~ + 2mm; for heavy rail 0 ~ +
3mm", "car the car has a safety rail and heavy rail clamp deviation
surface (including the side and the top surface) and the
installation of the reference line should not exceed 0.6 / 5000mm.
Elevator guide rail installation, testing and problems of
traditional methods
Installation:
Elevator guide rail installation method is currently taking place
model planes hanging wire hammer approach. As you know, the Earth's
gravity center of the earth is the point, hammer hanging line
method is to use the Earth's gravitational field, will be a ф0.6
piano wire around the upper end fixed, the lower end of a hammer
hanging under gravity, which roots Wire is a "plumb line." Hanging
weight seemingly simple and accurate method, but in fact very
difficult to guarantee the construction site vertical quasi
accuracy.
First, the wire hanging hammer itself is also a swing, the role of
the Earth's rotation and external forces, the weight will be kept
for a certain period of swing, a 100 m long heavy hammer, swinging
period and up to 20 second, it is difficult to stop, so often at
the bottom with a barrel filled with oil, the oil will increase the
weight placed on the damping to minimize "pendulum" of amplitude.
Hammer swing is not only time consuming, but also seriously affect
the accuracy. Secondly, the weight of the hanging line is a
flexible line, it is susceptible to the hoistway wind, especially
on cross-wind, a 100 m-long 10 kg weight, if only by one gram in
weight at the lateral force (equivalent to an ant the size of the
force strength) effects, it will make the suspension wire deviation
10 mm at 100 meters, which is about 20 arcseconds error, again,
hanging wire is a tensioned string, it is prone to the transverse
and longitudinal vibrations the transmission of vibration caused by
fluctuations. Seen from the above, the suspension wires seemingly
simple and accurate, in fact, the construction site is indeed
difficult to ensure a vertical quasi precision. This is also the
reason for many years people have been pursuing laser vertical
quasi methods. In contrast, laser vertical collimator having a
highly collimated, high vertical quasi resistance, high stiffness,
high stability, free from outside influence, are hanging wire
unmatched.
In addition, the traditional installation process on two rails side
face coplanarity (twisted) usually seek feet resolved, but the
amount of twist the rails difficult to achieve quantified control,
largely dependent on the skills of the installer. The number JZC
laser vertical collimator explicit target laser pointing the light
at the bottom of the two rails coplanarity provides fast and
accurate measurements.
Test:
Elevator installation after commissioning acceptance testing to be
performed at this time has no scaffolding, and generally model
planes, steel baseline also removed, usually five meters acceptance
department hammer to detect the magnetic field lines.
1) The detection methods, each measuring up to five meters is
detected, and each time the measurement has a benchmark, so
multiple measurements, the cumulative error is large, the data can
not be accurately guide the entire process.
2) rail deviation amount (X), (Y), with 5 noodle hammer can only be
measured in the X direction, and then measuring the Y-direction, so
that reference is constantly changing, obviously the measurement
error is large.
3) Face rail side coplanar question (twisted rails), due to the
large scale of seek errors, generally only controlled at 0.2 ~
0.3mm, the margin of error can not meet the actual needs, it is
difficult to make twisted rails the amount of analysis that the
conventional elevator installation guide detects the outline simply
no distortion of the test items, and the "guide distortions"
happens to be a lot already, "straightening rails", the key can not
be comfortable running.
Maintenance and reconstruction:
After the elevator running, rail due to the building settlement,
concrete shrinkage, the impact of the car to run mechanical
friction, etc., are inevitably occur rail displacement and
deformation, but lift a hammer hanging line after running can not
be used, there is no baseline, rail maintenance, bias correction,
there are many difficulties. In the elevator car overhaul update,
when corrected rail, usually re scaffolding, put the model planes,
hanging hammer-drawn steel wire and other measures, so
time-consuming, laborious, increased the number of maintenance
costs.
