Difference between switch tamper and line tamper

Difference between switch tamper and line tamper

The switch tamper in the tamper and the line tamper have a similar appearance, have a similar function, and are both hydraulic tampers, so how should we tell the difference between them?

 

 

 

The hydraulic switch tamper is suitable for the tamping operation of the most complex and difficult switch section in line maintenance and repair. The switch part, switch connection part, switch and guard part can be tamped, which can meet the needs of railway ballast tamping operation.

Technical parameter

1, internal combustion engine power 9.6kw (Honda GX390)

2, vibration frequency 60 ~ 67Hz

3, exciting force 22kN

4, the working system oil pressure 5-6MPa

5, the depth of tamping pick under the pillow 110mm±10mm Basic structure and working principle

Basic structure: The hydraulic switch tamper is composed of two parts: running frame and tamping device. The tamping device is composed of oil tank (including internal combustion engine, gear pump, hydraulic control valve), vibration frame and tamping pick.

The oil tank is driven by the lifting cylinder to drive the vibration frame, so that the tamping pick is inserted into the ballast or raised; The ramming pick is driven by the oil cylinder to achieve tensioning or clamping.

The internal combustion engine drives the eccentric iron of the vibration frame by belt to make the vibration shaft rotate to produce vibration, and the ballast stone of the ballast bed becomes dense through the violent vibration of the ramming pick.

 

 

 

The hydraulic line tamper can be used in domestic type II, type III concrete sleeper on the ballast line, can also be used in various foreign concrete sleeper and steel sleeper lines for tamping operations. The main technical performance is higher than the old tamping machine. The machine is suitable for different types of rail and concrete sleeper lines after large and medium repair cleaning operations of the tamping operation; It is also suitable for the tamping operation of ballast in new track bed. The machine has the advantages of superior performance, reasonable structure, safe and reliable, high working efficiency, and fully meets the needs of railway ballast tamping. New features on the basis of the performance of YD-22II hydraulic tamper:
1. The bottom frame of the tamping machine is equipped with a running device and an operating pedal (the bottom of the pedal is equipped with a spring shock absorber) to realize automatic running, improve working efficiency and operating comfort, and reduce labor intensity.
2. The two sides of the tamper are installed with protective nets to ensure the safety of the operators and the stability of the tamping operation.

Working principle: The hydraulic line tamper is powered by the gasoline engine and drives the oil pump and vibration shaft respectively through the triangle belt. The eccentric body rotating with the vibration shaft at high speed generates the exciting force due to the centrifugal force, and the high-pressure oil output from the oil pump enters the lifting cylinder and clamping cylinder through the reversing valve, thus driving the executive components to achieve the clamping rail, lower insertion, clamping and other tamping operation functions.
