Embodiment Construction

[0016] figure 2 , image 3 Among them, this embodiment includes a set of gear transmission mechanism 20 and two tamping arms 8 for tamping a single sleeper, which are symmetrically arranged laterally along the steel rail 23 with respect to the vertical symmetry line in the middle. The inner and outer two tamping picks 1 on the same side keep a certain distance to meet the clamping width. The oil motor 14 is respectively connected to the eccentric sleeve 22 through the two driven gears of the gear transmission mechanism 20. The eccentric sleeve 22 has a vibrating shaft 6, and the middle part of the tamping arm 8 is fixed on the outside of the vibrating shaft and is linked with the vibrating shaft. The tamping arms are connected with respective independent clamping oil cylinders and tamping picks 1 . The left arm clamping oil cylinder 17 is equipped with on the tamping arm 8 top of the left side, and the right arm clamping oil cylinder 11 is equipped with on the tamping arm 8...

Abstract

The invention relates to a switching turnout tamping device. An oil motor is connected with an eccentric transmission mechanism by a gear transmission mechanism, wherein the middle part of each tamping arm is installed on and interlocked with the eccentric transmission mechanism, and clamping oil cylinders are respectively installed on the tamping arms. The other end of each clamping oil cylinder is fixed on each oil cylinder permanent seat of a box body, each pick wrist is connected with the lower part of each tamping arm by a pick arm pin roll, the pick wrists are respectively connected with each tamping pick, one end of each turnover oil cylinder is installed at each pick wrist, and the other of the turnover oil cylinder is fixed at each tamping arm. By utilizing the gear transmission, the switching turnout tamping device causes the eccentric transmission mechanism to drive the tamping arms to make the circular movement together; being retrained by the clamping oil cylinders, nodal points on the upper ends of the tamping arms force the lower tamping picks to make relative movement to generate elliptical vibration when the lower tamping picks are contacted with ballast, thereby compacting the ballast; and by the reciprocating movement of pistons, the clamping oil cylinders which are respectively arranged along both longitudinal sides of each sleeper cause the tamping picks on both sides to clamp the ballast. The switching turnout tamping device can cause the tamping picks to be turned over upwards so as to meet the different requirements of operations under double-pick, single-pick and non-pick downward insertion states.

Description

Technical field [0001] The invention relates to a railway line maintenance equipment-a tamping device, in particular to a turnout 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 compactness of the ballast under the pillow, and at the same time cooperate with the track opening device to eliminate the deviation of the track, so that the track is smooth and stable. The turnout tamping device mainly works in the turnout area. There are point rails, guard rails, fork centers, etc. in the turnout area, and it is often encountered that the double picks cannot be inserted simultaneously between sleepers. Between individual sleepers, it may happen that a single pick cannot be inserted down. Therefore, the turnout tamping device requires the tamping pick to be ...
