Problems solved by technology
The existing tamping device realizes the adjustment of the clamping width by using the cylinder to control the widening block. The cylinder is prone to failure during application, resulting in the failure of the clamping width adjustment, which affects the lower insertion position of the tamping pick, and cannot adapt to different pillow types and lines. Requirements for sleeper width and sleeper spacing in different sections

The invention relates to a tamping device. A clamping oil cylinder which can cause a tamping arm to be relatively unfolded and folded along the longitudinal direction of a trackway is installed at the upper part of the tamping arm, and a tamping pick is installed at the lower part of the tamping arm. A width adjustment oil cylinder is installed on the clamping oil cylinder, and one stroke dog is corresponding to the width adjustment oil cylinder. The width adjustment oil cylinder is interlocked with the cylinder body of the clamping oil cylinder; and the stroke dog controls the piston stroke of the relevant clamping oil cylinder when the cylinder rod of the width adjustment oil cylinder is extended out or retracted, and the stoke of the piston of the clamping oil cylinder is corresponding to the stroke of the tamping pick in clamping ballast. The outward extension or the retraction of the piston rod of the width adjustment oil cylinder changes the stoke of the piston of a clamping cylinder interlocked with the width adjustment oil cylinder, and the changed stroke of the piston of the clamping cylinder is corresponding to the new stroke of the tamping pick in clamping the ballast. The tamping device solves the disadvantage of instable clamping width adjustment performance of the existing tamping device, and different strokes of the tamping pick in clamping the ballast can realize the operation under the circumstances of different sleeper types and different sleeper pitches, thus the operation can be reliable.
Description
Technical field [0001] The invention relates to a railway line maintenance equipment - a tamping device. Background technique [0002] The tamping device is a working device on the tamping car for tamping the ballast between the pillows on both sides of the rail and the ballast under the pillow. By tamping the ballast on both sides of the rail to increase the density of the ballast under the pillow, and at the same time cooperate with the lifting device to eliminate the undulation of the track, so that the track is smoother and more stable. [0003] In the existing tamping device, the vibration during work all belongs to the swing vibration of the eccentric connecting rod (similar to seesaw type vibration), clamping type tamping device. Chinese Invention Patent Application Publication CN1125281A discloses a tamping device, which can tamp two adjacent sleepers at the same time, one of the outer tamping mechanisms can be raised and lowered independently, and has a driving dev...
