YTF-400Ⅱ type hydraulic rail gap adjuster overall dimensions

1. Scope of application
-Type II hydraulic rail gap adjuster is suitable for line adjustment of various types of rails. The machine has two functions: pushing and pulling the rail seam. Both pushing and pulling the rail can be operated easily, with high work efficiency. It has anti-jamming function and is safe to use.
2. Main technical parameters

.Quality of the whole machine (including hydraulic oil)
3. Basic structure and working principle
1. Basic structure: mainly composed of running wheels, inclined iron, clamp body, safety It is composed of pin, return spring, safety lowering device, oil tank, oil cylinder, oil pump, relief valve, oil return valve, tie rod and other parts.
The main structure is as shown in the figure: front clamp body, piston rod, oil cylinder, oil return valve (the other side is the backup oil return valve), middle clamp body, tie rod, inclined iron (block), rear clamp body, large safety Pin, lever, oil pump rocker, oil tank, return spring, small safety pin (piece).
(ii) Working principle:
When increasing the rail gap (i.e. pushing the rail): Use the front clamp concrete and the middle clamp concrete and the rear clamp concrete not to participate in the work. Press the hydraulic oil into the double clamp through four plunger pumps. The piston in the oil cylinder extends outward, and the inclined iron in the front and middle clamp body clamps the two rails and then pushes the rails to increase the gap between the two rails to achieve the purpose of adjusting the rail gap.
When narrowing the rail gap (i.e. pulling the rail): Use the middle and rear clamps to clamp the concrete and the front clamp to not participate in the work. The hydraulic oil is pressed into the double cylinder through four plunger pumps. The piston extends outward through the pull rod, so that the inclined iron in the middle clamp body and the rear clamp body clamps the two rails and then pulls the rail to narrow the gap between the two rails. The purpose of adjusting rail seams.
4. Usage and maintenance
Correct use and maintenance play an important role in ensuring the normal operation of the machine and extending its service life. The operator should read this manual carefully to understand the structure and function of each part.
(1) Inspection before use
Whether the oil level in the fuel tank reaches the height of the fuel tank/summer use #oil in winter #oil should be filtered when refueling.
Whether the control part is flexible and reliable.
Whether the oil return valve opens and closes normally and whether all hydraulic parts work normally.
Check whether the fastening parts of each connection are loose and whether there is oil leakage.
(ii) Operation steps
Place the machine tool at the joint of the two rails being adjusted. When the rail needs to be pushed, the rail seam should be located between the front clamp body and the middle clamp body. When the rail needs to be pulled, the rail seam should be located between the front clamp body and the middle clamp body. Between the middle clamp concrete and the rear clamp concrete.
, Move the control lever on the corresponding clamp body downward to make the clamp body fall on the rail.
. Tighten the oil return valve clockwise and use the joystick to shake the rocker of the oil pump to input the hydraulic oil into the working cylinder. When the piston is extended, the inclined iron can clamp the rail and continue to shake the joystick to achieve the purpose of adjusting the rail seam. .
,Attention! When pushing the rail, gently pull the lever handle on the rear clamp body upward so that the inclined iron and the rail do not touch. When pushing the rail, gently pull the lever handle on the front clamp body upward so that the inclined iron does not touch the rail.
After each rail gap adjustment, you should first unscrew the oil return valve in the counterclockwise direction, then move the lever upward to loosen the inclined iron, so that the working cylinder piston will be reset under the action of the tension spring to complete a working cycle. (This machine is equipped with two oil return valves. When one of them fails, open the other oil return valve to reset the oil cylinder, which improves the safety performance of the machine.)
After completing the operation, move each clamp upward. The lever on the rail will push the running wheel onto the rail surface through the pawl to the next rail seam or the lower track of the whole machine.
There is a relief valve in the fuel tank. The pressure has been adjusted before leaving the factory so that when the load is too large, the relief valve unloads to ensure the safety of the machine.
If the workload of rail pushing is large, it is recommended to remove the rear clamp body and tie rod to reduce the weight of the whole machine.
