Definitions

  • the invention relates to a tamping unit for track tamping machines for tamping a group of adjacent sleepers of a track, with tool carriers arranged one behind the other in the longitudinal direction of the track and independently adjustable in height, and tamping tools mounted thereon for plunging into the ballast and for tamping a threshold with the aid of an auxiliary drive can be provided to each other in the longitudinal direction of the track.
  • Such a tamping unit is known from DE-A1-2 426 841 and is designed for the simultaneous tamping of a group of three immediately successive track sleepers.
  • This tamping unit has two tool carriers, which are mounted one behind the other in the longitudinal direction of the track, independently of one another, on vertical guide columns, and are positioned above the two outer sleepers of the group of three.
  • Each tool carrier is equipped with an eccentric shaft and three tamping tools connected to it, of which two tamping tools can be provided to each other in the longitudinal direction of the track and form a pair with which the outer threshold is tamped.
  • the third tamping tools of each of the two tool carriers are arranged in such a way that together they form a further pair associated with the middle threshold, and are likewise designed to be able to be provided in the longitudinal direction of the track.
  • the side movements are carried out using hydraulically operated spindle drives.
  • a tamping unit for the simultaneous tamping of three adjacent sleepers is also described, which is formed from two tool carriers mounted on a machine frame at a distance of two sleepers from one another.
  • Each tool carrier has a pair of tamping tools, which are connected to one another by means of an auxiliary drive, which are immersed in the ballast on both sides of the first and third threshold of the group and for tamping them in the longitudinal direction of the track be moved, each darning tool has its own vibrator.
  • the hydraulic cylinders forming the auxiliary drives are acted upon in opposite directions, as a result of which the facing stuffing tools of each of the two tool carriers move towards one another.
  • the opposite movement of the two outer tamping tools furthest apart in the longitudinal direction of the track is stopped by stops.
  • DE-A1-2 460 700 also discloses to fasten three pairs of tamping tools for tamping a group of three sleepers on a single tool carrier. As a result, however, selective lowering of only a part of the tamping tools, for example in the presence of a track obstacle, is not possible.
  • the object of the present invention is to provide a tamping unit of the generic type with which a more economical tamping of the track can be achieved with a construction that is as simple as possible in terms of construction.
  • a tamping unit described at the outset which is characterized by a first tool carrier having three tamping tools arranged one behind the other in the machine longitudinal direction and a second tool carrier having two tamping tools arranged one behind the other in the machine longitudinal direction, at least the auxiliary drive of the one adjacent to the first tool carrier and the second Tool carrier mounted tamping tool is designed for a first auxiliary movement of the two tamping tools to each other and for a second auxiliary movement of each other.
  • Such a design of a tamping unit with a different number of tamping tool carriers in combination with a special, two-tamping auxiliary drive allows a particularly extensive adaptation to different tamping conditions. These can be predetermined, for example, by different threshold distances, tamping obstacles and switch sections and would make the simultaneous lowering of a large number of tamping tools one behind the other in the machine longitudinal direction difficult or impossible. Due to the asymmetrical tamping tool distribution with respect to the tool carrier, on the one hand a too tight arrangement of the tamping tools, which is structurally very difficult to solve, is avoided and, on the other hand, a gradual connection of the individual tool carriers is made possible depending on the track conditions. This is the first time that a particularly high tamping capacity has been achieved in connection with the possibility of using even under difficult track conditions, e.g. in turnout sections, continuous tamping guaranteed.
  • a motor 10 is for the power supply of a travel drive 11 and the other, by a control device 12 by one Work cabin 41 is provided from controllable drives of the machine 1. The working direction is indicated by an arrow 13.
  • the tamping unit 7 is fastened on an unit frame 14 connected to the satellite frame 6.
  • the tamping unit 7 is composed of three tool carriers 15, 16 and 17 arranged one behind the other in the longitudinal direction of the track, of which the middle tool carrier 16 with respect to the longitudinal direction of the machine or the longitudinal direction of the track is hereinafter referred to as second and the other two tool carriers 15, 17 as first and third, respectively Tool carriers can be named.
  • Each tool holder 15, 16, 17 is mounted on two vertical guide columns 18 of the assembly frame 14 by means of its own height adjustment drive 19, independently of the other two tool holders, and each is equipped with its own eccentric shaft 20.
  • the first and third tool carriers 15, 17 each have three tamping tools 23, 24, 25 and the second tool carrier 16 have two tamping tools 22 spaced apart from one another in the machine longitudinal direction.
  • the Darning tools 22 to 25 are arranged symmetrically with respect to a plane of symmetry 42 running perpendicular to the longitudinal direction of the machine.
  • Each tool carrier 15, 16, 17 has two tamping tools opposite one another with respect to the cross-machine direction, so that with the lowering of the tool carrier 15, 16, 17 two tamping supports, each adjacent to a longitudinal side of the rail, can be tamped.
  • an additional lifting unit 31 can be seen - which can be used in an embodiment variant and shown in dash-dotted lines - which, similar to the track lifting / straightening unit 8, has a lifting element 32 designed as roller pliers for positive locking and lifting of the rail 21
  • Track 3 has and is height-adjustable connected to the satellite frame 6 or arranged on the unit frame 14.
  • a measuring axis 30 belonging to the machine's reference system for registering the track position, which is mounted on the satellite frame 6.
  • the tamping tools 22 to 25 are designed in pairs in relation to one another in the longitudinal direction of the track by means of their auxiliary drives 28, the tamping tools 25 and which are the most distant from one another in the longitudinal direction of the track the adjacent tamping tools 24 of the tool carriers 15 and 17 each form a pair assigned to the outer sleepers 33 and 37 of the group 29.
  • the tamping tools 22 of the second tool carrier 16 also form a pair for tamping the central threshold 35, although their auxiliary drives 28 are also designed for a second auxiliary movement of the tamping tools 22 from one another in addition to this first auxiliary movement.
  • the two supply drives 28 of the second tool carrier 16 are each assigned a blocking drive 44, which is designed as a cylinder-piston drive. If this is activated (as in the position shown here), the pivoting movement of the stuffing tool 22 about the axis 27 is blocked in the vertical central position, i.e. it is only possible to pivot the two tamping tools 22 in the direction of one another.
  • the tamping tool 22 can also be pivoted in the direction of the adjacent tamping tools 23 of the tool carriers 15 and 17 by means of the auxiliary drive 28 beyond the central position.
  • the blocking drive 44 can of course also be designed differently, for example as a solenoid-actuated bolt, etc.).
  • FIG. 3 shows the first phase of the two-phase operation of the tamping unit 7 for the simultaneous tamping of a group 29 of sleepers 33 to 37.
  • All tamping axes 26 are lowered into the ballast by lowering the three tool carriers 15, 16, 17 using the height adjustment drives 19 immersed and the tamping tools 24 and 25 of the first and third tool carriers 15 and 17 each provided to each other in order to stuff the sleepers 33 and 37.
  • the tamping tools 23 of the tool carriers 15 and 17 and the respective tamping tools 22 of the second tool carrier 16, which are adjacent to each other are also provided to one another in order to stuff the sleepers 34 and 36 (see small arrows and hatching of the sleepers). Then all three tool carriers 15, 16, 17 are lifted.
  • FIG. 5 The embodiment variant of a tamping unit 43 according to the invention shown in FIG. 5 essentially corresponds to the tamping unit 7 in FIGS. 1 to 4 in a reduced or simplified form. The same reference numerals are therefore retained for parts with the same function.
  • the tamping unit 43 has only two tool carriers, namely a first tool carrier 15 with three tamping tools 23, 24, 25 arranged one behind the other in the longitudinal direction of the machine, and a second tool carrier 16 with two tamping tools 22.
  • the auxiliary drive 28 of the second tamping tool 22 adjacent to the first tool carrier 15 Tool carrier 16 is designed for a double or counter-rotating auxiliary movement (as in the tamping unit 7), while the second tamping tool 22 as well as the tamping tools 23, 24 and 25 of the first tool carrier 15 are equipped with auxiliary drives 28 which can only be acted upon.
  • the tamping unit 7 or 43 directly on the machine frame on a tamping machine which can be moved step by step from tamping to tamping point.
  • the tamping picks can be fastened on the respective tamping tool 22-25 in a known manner by means of a drive, pivotable laterally about an axis running in the machine longitudinal direction.
