1 scope
This technology is applicable to rated load
5000kg and below rated speed 3M/s and the following types of Chinese-made
traction lifts for installation works.
2 construction preparation
2.1 devices, materials requirements:
2.1.1 specification shall conform to the
design requirements, full, firm, and free from distortion and damage.
2.1.2 to guide and fixing screw for guide
specifications, quality, quantity shall conform to the requirements.
2.1.3 adjusting shims should meet the
requirements.
2.2 the main tools:
Chain, wire rope, wood side.
2.3 operating conditions:
2.3.1 for DIN rail mounting, adjustment,
after acceptance, dismantled a local scaffolding stalls on the ground floor in
order to be able to enter the shaft in place.
2.3.2 in hoistway tidy line, lighting and
other welding, convenience of operation site.
3 operational processes
3.1 process:
Lifting preparation before hoisting the
heavy framework → work → guide → boot installation, adjustment of the weights is installed and fixed
3.2 lifting preparations:
3.2.1 in the corresponding position on the
scaffold (to facilitate lifting the frame and mount Tuo block for example)
installation platform (Figure 5-32).
3.2.2 in the proper height (for easy
lifting on whichever) two heavy rail bracket attach the wire rope, wire rope
Center hung a chain. Steel wire rope should be tied to the guide rail bracket,
is not directly tied to the Rails to avoid rail force and displacement or
deformation.
3.2.3 in the buffer on each side of a
100mmx100mm wood side. Wooden height C=A+B+ distance (Figure 5-33).
The distance shown in table 5-8.

3.2.4 If the guide shoe for spring-mounted
or stationary, to two of the same side of guide shoe removed. Guide roller, to
four guide shoe removed.
3.3 the hoisting the framework:
3.3.1 the framework shipped to platforms,
wire rope pull on rope hitch plate and chain hook together (Figure 5-34).
3.3.2 operation pour chain, slowly will on
heavy framework hanging up to scheduled height, for side with spring type or
fixed type guide boots of on heavy framework, mobile on heavy framework, makes
its guide boots and the side guide anastomosis and keep contact, then gently
relax pour chain, makes on heavy frame smooth firm to placed in prior support
good of wood party Shang, not loaded guide boots of on heavy framework fixed in
wood party Shang Shi, should makes framework two side and guide end surface
distance equal.
3.4 installation, adjustment to the Guide:
3.4.1 stationary guide installation to
ensure the lining and clearance of rail-side upper and lower line if it does
not meet requirements to be used to adjust (Figure 5-35). 3.4.2 in prior to
installing the spring-loaded guide roller, guide roller adjusting nut should be
tightened to the maximum, no clearance between the Guide and guide shoe rack,
which makes it easier to install (Figure 5-36).
3.4.3 If the guide roller slider-lined
upper and lower inconsistent with track-side side gap, between Guide and
counterweight frame shim adjustments, adjustments with stationary guide roller.
3.4.4 install roller guide shoes flat,
roller guide after pressing rollers on either side should be equal to the
amount of pressure spring, compressed size should be as stipulated in the
factories. If no provisions are adjusted according to the usage pressure
moderate front wheel and road surface compaction, wheel alignment guide from
the Center Center (Figure 5-37).
3.5 installation and fixing of the weights:
3.5.1 into a corresponding number of the
weights. Number of weights should be calculated according to the following
formula:
Mounted on blocks =
3.5.2 design according to manufacturer
requirements put on the block mounts. Figure 5-38 for the flapper mounts.
4 quality criteria
4.1 project:
The upper and lower guide roller should be
in the same vertical line, skew, twist is not allowed.
4.2 Basic project:
Guide roller Assembly should comply with
the following requirements:
4.2.1 using a rigid structure, able to
guarantee the normal operation, and two rail ends with two guide surfaces and
is not more than 2.5mm.
4.2.2 using the flexible structure, able to
guarantee the normal operation and end face with guide roller slider surface
without gaps, guide shoes spring telescopic range is less than 4mm.
4.2.3 use roller guide roller guide does
not skew, even pressure, Center, and in contact with the Rails face even on the
entire flange width (see 3.4).
Inspection method: observation and standard
checks.
5 finished product protection
5.1 the guide shoe after installation,
using things like old cloth for protection, so as to avoid dust residue into
the boot lining, affect its service life.
5.2 construction should pay attention to
avoid falling objects to prevent smashing guide shoes.
5.3 the framework of transport, lifting and
loading Tuo block process, be careful, do not hit have been renovated floors,
walls and Rails and other facilities, if necessary, to take the appropriate
protection measures.
6 quality problems to be noticed
6.1 boot after installation and adjustment,
each screw must bear in prison.
6.2 screw hole location if the individual
does not meet the installation requirements, and can be resolved. Never allow
empty without it.
6.3 in heavy lifting, don't touch the
baseline, so as not to affect the installation accuracy.
