dial the way work.
Hydraulic transmission principle as shown
Four, method of use
1, check the fasteners whether firm, if have, become loose, must
first for fastening, then in the operations, to ensure safe use of
machines and tools.
2, before use, should to be injected fuel tank about 3/4 ~ 4/5
place (about *0 liters) clean hydraulic oil, according to the local
climate conditions and different season, general provisions summer
choose *0 #, winter choose *0 #, in use found oil quantity is not
enough, should be added hydraulic oil.
3, engine is the power source, before use should first reading
engine specification, familiar with the matters needing attention
and operation method, ensure the normal operation and prolong
service life.
4, multiple valve equipped with overflow valve, the system pressure
has been tuned, do not need to adjust, if we need to adjust,
pressure no more than *6 mpa.
5, before the use should first check the hydraulic oil is enough,
and open multiple valve control handle (1), check each part
separate action is normal or not. Should be familiar with the
directional valve direction (in plate) and to ensure that the
correct control.
6, track, dial the way operation program of work:
6.1 will play a dial the way machine placed in orbit, start the
engine (*8), make its light run 3 ~ 5 min, check each part work is
normal or not.
6.2 multiple valve control handle (1) there are four (according to
the plate sure), the lateral two separate control two lifting oil
cylinder (4) and (5). Intermediate one operating handle control
hook rail institutions and travel agency (8), the rest one control
dial the cylinder (*1) make lifting oil cylinder (4) tilt. Must be
familiar with the control valve action.
6.3 track and dial the way work, before intermediate multiple
directional control valve handle to "hook rail" position. Make
mention rail hook (*5) firmly hook rail palatine. Then select track
homework or dial the way homework, according to the following
requirements in the operations.
6.4 track homework;
In the track assignments, determine the lifting oil cylinder (4)
and (5) in vertical state, two limit pin must respectively inserted
in limit pin hole (7), otherwise in the track process medium oil
cylinder easy to tilt, according to operation need (the single or
double track) will be left, right control lifting cylinder handle
to "up", leg stretched out, and began to track. In the process of
operation according to the need to control track quantity, two oil
cylinder discriminability leveling. Homework finished, will be back
leg (*3).
6.5 dial the way homework; Two limit pin must limit the hole from
pull out, oil cylinder (4) have Angle limit, the oil cylinder (5)
have protection limit, according to dial the way direction, control
dial the cylinder handle, make two lifting oil cylinder to "left";
Or "right" tilt, not overexert open reversing valve handle, want to
observe lifting cylinder inclined swing speed, proper adjustment,
to lift the oil cylinder (4) completely inclined depend on to the
left or right limit, began to dial the way work. First the two
lifting cylinder control handle to "up (dial the)", make lifting
cylinder piston rod stretched out, and lifting oil cylinder (5) of
the piston rod out quantity in close condition must be greater than
lifting oil cylinder (4) of the piston rod out quantity, (best more
than **0 mm) then starts to dial the way work. According to dial
the way quantity size determine control handle. If must dial the
other side rail, first leg (*3) back, should pay attention to
piston leg (*3) whether with rail bottom collision, such as
collision should adjust Angle, then back leg (*3). Garnish with
dial the cylinder switch to the corresponding position, make
lifting cylinder tilt to the other side, its operation method as
above. Homework finished, will support legs ballast clean up.
As time homework not up to dial the way quantity can duplication of
work. Such as piston out length is insufficient, can not reach
scheduled dial the way quantity, can be in piston leg inclined
support plus mat sleeper block can.
6.6 up, dial the way homework completed, will be left, right
lifting cylinder control handle
6.7 a switch or meet other obstacles, leg completely withdraw, will
be hook line cylinder control lever switch to "pine rail", to stand
up to the highest position, can implement.
6.8 if you need the way, don't put petrol engine flameout, first to
press 6.6 and 6.7 a operation, then the auxiliary road frame from
the other side of the road to wear into, insulating section stuck
rail lateral, and then will road frame on the can and auxiliary
road frame connected place and conjunction, place smoothly, open
intermediate multiple directional control valve handle to "hook
rail" position, make go road wheel (8) raise, lift rail hook (*5)
did not hook rail, ensure the equipment in the parts are not
affected by rail barrier, put out after the engine. Promote
hydraulic up dial the way machine to road frame finally end, with
fixed pin will road wheel fixed well, remove the auxiliary road
frame and put them in the clearance outside the safety position
can.
7, when need manual pump work, just move the pressure can be, other
operating unchanged.
