Description
LB - **0 type electric bolt wrench is suitable for railway line
sleeper bolt and nut of unscrew and fastening operations. This
machine is double sleeve at the same time in the operations, large
torque, the operation focused, can satisfy the rail fastener
locking torque, convenient and quick. On the base with a rotary
four-wheel walking device, can be in already land walk, and walk on
orbit, and handling convenient, it is loose and tight sleeper nut
instead of numerous hard physical labor ideal special tool.
Second, the main technical parameters
1, motor type: Y**0L - 2
2, the motor rated power: 3.0 kW
3, motor speed: ***0 r/min
4, spindle speed: ******0 r/min
5, sleeve quantity: 2
6, sleeve center distance: **4 + 0.5 mm
7, tightening torque adjustable: *****0 N, m
8, maximum unscrew torque: > **0 n, m
*0, work efficiency: acuities *0 / points
*1, quality. *2 kg
*2, physical size: **5 x **0 x **0 (mm)
Three, the basic structure and working principle
Working principle: by the motor drive, drive gear reduction, after
fork for reversing, through a circular bevel gear, solitary, torque
to jaw clutch, will set up good torque to main shaft sleeve. Basic
structure:
As the chart: the 1 motor Y**0L - *2 frame, 3 auxiliary support
sleeve, 4 operation put, 5 torque adjustable handle, 6 reversing
handle, 7 torque scale cover, 8 adjusting screw, 9 sleeve assembly,
*0 go road wheel assembly.
Four, method of use
1, check the drive part is flexible, threaded connection is
loose.
2, toggle the reversing handle 6, make socket wrench work the part
is in an intermediate position (space).
3, will reducer upper oil cup and the rotary sliding parts add
lubricating oil.
4, will auxiliary support insertion auxiliary support set of three
days.
5, connect power, starting motor short idle motion, observe the
motor rotation direction is and the sign (red arrows) the direction
consistent, such as not consistent, stop, change the power phase
sequence, wait for rotating direction, running normal, and then
began to work. Otherwise may not work.
6, open the reversing handle six to need to spin loose (left side
position) or tight (the right position), alignment nut by hand to
support the operation of 4 to press and keep a nut, can to nut
tightening and loosen the homework.
7, in tightening, heard clacker (has reached set torque), can raise
sleeve 9.
Eight, the work is completed, shut off the power and will be
machines and tools to implement safety clearance outside.
9, remove the auxiliary support.
Five, machine maintenance
1, this machine please assign special personnel to use, before each
use, please be sure to in the rotating place, oil cup, add clean
oil, each working *0 hours later, will torque scale cover next bolt
loosened, downward, clutch, spline shaft, copper bush added
molybdenum disulfide grease.
2, torque adjustment: torque adjustable handle 5 the lock nut to
loosen, the rotary torque adjustable handle 5, counterclockwise to
reduce, clockwise to increase, with kg wrench measured and
determined, with locking nut lock. When factory, each machine motor
wrench adjustment tightening torque is about **0 ~ **0 n · m, such
as in the radius is less than **0 m curve location operation, or
according to the construction requirements, torsion moment more
than **0 n · m. Torque spring USES period of time may fatigue
failure regularly adjust.
3, the machine design the torque protection key, when unscrew nut
torque more than **0 n · m, insurance key is cut off, in order to
protect spline shaft and machine other parts not a torque and
damage.
4, change protection key: torque scale cover, clutch, spring
dismounting, with screwdriver will the clutch upward pry up, in
order to remove the parts pack good, charging molybdenum disulfide
grease, and then torque scale cover screw well.
5, in order to adapt to different specifications of the rail, need
to adjust to adjusting screw 8, meet different rail type height
requirement.
Six, the matters needing attention
1, before using the power wire, plug and check whether the switch
is good, otherwise cannot use. Insert the power socket ago, motor
switch should be in the "off" position. Plug, plug must match, and
correct ground.
2, don't make the power cord contact heat source, grease. Prevent
power cord chafe, cut, rolling bad.
3, in handling process take care, in order to avoid damage to the
machine.
4, such as torque is not adjust torque adjustable handle 5, the
output torque requirements so far, usable kg wrench
measurement.
5, long time no, should be placed in ventilated, dry, no corrosion
gas in the warehouse. Such as moisture or rain, before use ought to
use **0 v measurement insulation resistance by megger, electrical
device to stand insulation resistance not less than 7 m Ω.
