Shenyang tamping machine is a small road maintenance machine suitable for railway track bed maintenance. It is mainly used for tamping ballast track bed. The utility model has the advantages of novel design and compact structure. It is a tamping equipment with fast up and down track and light operation, which is especially suitable for turnout tamping operation. The machine is mainly composed of gasoline engine, damping device, transmission shaft, vibrator and handle to form an independent and complete hand-held tamping machine. There is neither lengthy cable nor bulky flexible shaft. The structure is reasonable and compact and easy to use.

The electric tamping machine is composed of control device, damping device, vibration source and pick plate. The vibration motor shell is made of aluminum alloy precision casting with good heat dissipation. The handle and the vibration source are connected by elastic rubber, and the angle can be adjusted by Sector splint. Its working performance can fully meet the tamping operation of the line and the tamping operation after screening.

The utility model comprises a chamfered wheel, an oil seal upper and lower cover, a hollow shaft support seat, an upper and lower oil seal, a motor, a lifting main shaft, a hollow shaft, a lifting main shaft bearing seat, an air cylinder, a cylinder support and a hollow shaft pulley. The hollow shaft is placed in the hollow shaft support seat, and the lifting main shaft is placed in the hollow shaft; The lower part of the hollow shaft support seat is movably connected with a lower oil seal, a lower cover of the oil seal and a chamfering wheel from inside to outside; The upper part of the hollow shaft support seat is successively sleeved with an upper oil seal, an oil seal upper cover, a hollow shaft pulley, a lifting main shaft bearing seat and a cylinder support from bottom to top; The upper part of the cylinder support is respectively provided with cylinders; After adopting the above structure, it can be automatically adjusted to coincide with the axis line of the hollow shaft during assembly, so as to improve the working stability and service life of the chamfering machine. In addition, because the lifting spindle bearing seat is a self-aligning bearing, the maintenance of the chamfering machine is simple and convenient.
