YD-22Ⅱ Railway Hydraulic Tamping Machine
The utility model Railway Hydraulic Tamping Machine is suitable for the overhaul of large rails and sleepers and the cleaning of the middle beds
Introduction of YD-22Ⅱ Railway Hydraulic Tamping Machine
YD-22Ⅱ Railway Hydraulic Tamping Machine collecting end-users’ experience at home and abroad, adopting new material and technology, this type of Tamping Machine is our upgrading product. Its basic structure and working principle reserves the original advantages, that is of double guide pillar frame and single cylinder lifting mode. Due to increasing the tine palm inserting depth and the guide pillar stroke stop means, it’s able to to operate on II type concrete sleeper and III type concrete sleeper, and on various concrete sleeper and rail track.
Its main technical performance is better than the old type. It’s suitable for tamping operation on various rail and sleeper track after the overhaul and medium maintenance ballast cleaning operation, and also suitable for tamping operation on the new track ballast bed.
This YD-22Ⅱ Railway Hydraulic Tamping Machine has the features of high quality performance, reasonable structure, safe and reliable operating capability and high working efficiency, which can satisfy the requirement of ballast tamping operation.
Basic Structure and Working Principle of YD-22Ⅱ Railway Hydraulic Tamping Machine
Working principle：YD-22Ⅱ Railway Hydraulic Tamping Machine is powered by petrol engine through triangular belt driving oil pump and vibrating axes respectively to generate pressurized oil and vibrating force, pressure oil passes through reversing valve into lifting cylinder and clamping-squeezing cylinder to achieve the process of tamping operation-rail clamping, inserting and inserting, rail clamping and ballast clamping-squeezing accordingly
Main Parameter of YD-22Ⅱ Railway Hydraulic Tamping Machine
GX390 Honda Petrol Engine
(1) Unilateral or bilateral off-track
(2) Bilateral next two as a group, for single
line shoulder a narrow area.
Preparation Before Working
A. Fill the oil tank with proper hydraulic oil according to the season and ambient temperature(generally, select the oil 40# in summer, 20# in winter), regarding the oil scale as norm.
B. Adjust the size of clamp jaw as per rail type.(The clamp jaw has been adjusted for 60kg/m rail before leaving factory)
C. Check if any part is loose abnormally .
D. Start the engine and check if the operation is normal without abnormal sound. If there is any abnormal phenomenon, stop the engine at once and check for troubleshooting, after which restart the engine and allow idling for 20 minutes at least.
E. While operating, move operating handle of reversing valve and check if the hoist cylinder and clamping-squeezing cylinder is working flexibly. Allow the cylinder to operate on a full scale for many times and check if there is any abnormal act.
F. The operating handle of hoist cylinder and clamping cylinder can work independently or synchronously.

G. Switch off the power, stop the operation of gear pump, operate the machine by using the manual hydraulic pump instead. The manual operation should be the same as when the power supplying to drive the hoist cylinder and clamping cylinder flexibly. It’s necessary to test and adjust the manual hydraulic pump well enough to be adopted in case of emergency.
H. Check whether the pick blade is loose or not, bolt is tight or not.
I. If the machine is driven by electric engine, check whether there is any leakage after the power is on, and check if the direction of rotation is right.
Yd-22 II Railway Hydraulic Tamping Machine
A. The operator should be familiar with the performance of this machine through training before operating it.
B. Put the travelling frame on the track, the travelling wheels should be aligned with both of the rail, push the two tamping machines (whose hoist cylinders are lifted up to the top) onto the flat traveling frame in turn, align the position respectively, plug the fore-and-aft king bolts in position holes. Then fold up the off-track frame, clasp the supporting hook of the off-track frame with the shackle of the traveling frame. While working, the operator had better face towards the direction of the train coming.
C. Connect the power source and turn on the combined switch ( If using petrol engine, start the engine manually and press the throttle to the working position ), carry out the tamping operation according to the track conditions. Once the tamping blade is inserted, one to three open-clamp cycles should be applied generally.
D. During working, the operator should keep a close eye on the operating conditions of the machine and the track conditions. The two operators should coordinate and cooperate with each other closely and make every operating step harmoniously..
E. If the machine is driven by electric engine, operator has to possess insulated protection article..
F. While tamping, should keep away from the obstructers such as the anti-creeper, gauge-rod and supporting wood.
G. After clamping the ballast, open the tine palm and at the same time shift the reversing valve lifting rod to lift the machine to the top position, then push it to the next tamping spot and continue operation.
