Definitions

  • MOBILE TRACK LIFTING APPARATUS Filed 001;. 20, 1960 INVENTORS FRM/Z PLkSSER BY JOSE-F WEURER United States Patent Office 3,149,578 Patented Sept. 22, 1964 3,149,578 MOBILE TRACK LIFTING APPARATUS Franz Plasser and Josef Theurer, both of Iohannesgasse 3, Vienna, Austria Filed Oct. 20, 1960, Ser. No. 63,788 Claims priority, application Austria Oct. 20, 1961 3 Claims. (Cl. 104-7) The present invention relates to mobile track lifting apparatus.
  • the weight of the machine will hold the previously graded track section down so that only the uncorrected track section engaged by the jack will be raised.
  • relatively light carriages to fix the track temporarily at given intervals at a desired grade before the permanent tamping operation is effected.
  • Such light track lifting carriages may be readily removed from the track at the approach of a train but their weight is not sufficient to hold the track section on which they stand down when the track jack is operated. If the light carriages were artificially weighted down, they would obviously become inefficient, cumbersome and difficult to remove from the track at the approach of a train.
  • a mobile carriage whereon a support member is pivotally mounted in the range of, i.e. at or near, its rear end, the support member extending in the direction of the track.
  • a ballast engaging element is mounted on the freely suspended forward end of the support member and one or more track clamping and lifting devices are mounted on the pivotal support member between the forward and rear ends.
  • the lifted track section is supported in part by the ballast engaging element and in part by the rear pivot of the supportmember. That portion of the track section weight which is supported by the rear pivot will exert a downward pressure on the previously graded track section underlying the rear pivot and will thus hold it stationary during raising of the uncorrected track section while the forward load will be transmitted excusively to the ballast by the ballast engaging element.
  • the pivotal mounting means is positioned in the range of, i.e. at or near, the rear axle of the carriage so that the weight of the track lifting apparatus and the weight of the lifted track section which is supported by the pivotal mounting means are added together at this point for optimum results.
  • pivot 5 constituting a means for pivotally mounting the support member 4 on carriage 1 is coaxial with the axle of the carriage rear wheels.
  • the freely suspended forward end of the support member, which extends in the direction of the track, is supported on the ballast by a hydraulic ballast engaging element 6 whose piston rod carries shoe 7 which engages the ballast.
  • A" first track clamping and lifting device 8 is mounted on the support member near its forward end and comprises a hydraulic cylinder and a rail clamping means mounted on its piston rod.
  • Hydraulic track jacks and track clamping and lifting devices are well known and any such conventional means may be used for the purposes of the present invention, these devices per se forming no part thereof aside from their combination with other elements thereof.
  • a second track clamping and lifting device similar 'to 8 is shown at 9 at a location about intermediate the rear and forward ends of the support member 4, track clamp ing and lifting devices 8, 9 being either fixedly or longitudinally adjustably mounted on the support member 4.
  • Device 9 is mounted at a point where the track section is to be raised to a desired level.
  • a tamper schematically indicated at 10 is mounted on the carriage adjacent the device 9 so that the track tie may be fixed at the desired grade level by tamping ballast thereunder. While the present invention is not concerned with any particular tamper, tampers of the type disclosed in our copending application Serial No. 5,228, filed January 28, 1960,
  • the grade level may be determined by a contact roller 14 or a like rail sensing element mounted at the end of a measuring rod 15.
  • the vertical measuring rod may carry a sensing element 16 whose contact with the horizontally extending tensioned wire 17 indicates that the desired grade level of the track has been reached.
  • the tensioned wire may be held taut by a guide roll 18 to establish a continuous reference line for obtaining a predetermined grade level. All this is known and forms no part of the present invention, except inasmuch as it constitutes a part of the total combination.
  • an optimum effect and efficiency is obtained because the carriage will pin down the previously graded and tamped track section underlying the rear axle of the carriage whereby the track jack means positioned at or closer to the forward end of the carriage will lift the track in an ideally curving line from the substantially fixed rear point.
  • the track jack closest to the fixed rear point is of essential importance for properly controlling the grade level of the lifted track section and, for this reason, a ballast tamper is preferably associated with this track jack so that the track may be fixedly positioned at this point.
  • the height of the rail clamping means of these jacks may be staggered so that the clamps of the forward jacks engage the rails later and thus automatically raise the track a little less than the more rearwardly positioned jacks.
  • the outstanding advantage of the track lifting apparatus of this invention resides in the fact that a considerable portion of the weight of the track section being lifted is transmitted by the pivotal support member 4 to pivot 5 Where it presses down on the previously graded track section underlying this pivot and thus tends to hold it in a fixed position.
  • This effect may, of course, be further enhanced if the entire apparatus is so built that most of its weight is shifted into the range of the carriages rear axle. It is, for instance, advantageous to mount the heavy actuating mechanism for the apparatus above the rear axle, as schematically shown in the drawing.
  • the lever action of pivoted supported member 4 may, as mentioned before, be adjusted according to desired conditions by varying the distances between the forward support 6, the track jacks and the pivot.
  • a mobile track lifting apparatus comprising a carriage, a support member extending alongside the carriage and having a forward and a rear end, the support member extending in the direction of the-track, a ballast engaging element mounted vertically movably on the support member in the range of the forward end and supporting the support member forward end on the ballast, pivot means in the range of the support member rear end pivotally mounting the support member on the carriage for pivoting in a plane extending in the direction of the track, and at least one track clamping and lifting device mounted on the support member intermediate the ballast engaging element and rear end, lifting means for moving the forward end of said support member vertically to lift the support member forward end in relation to the ballast engaging element during lifting of the track.
  • a mobile track lifting apparatus comprising a can riage with front wheels mounted on a front axle and rear wheels mounted on a rear axle, a support member extending alongside the carriage and having a freely suspended forward end and a rear end, the support member extending in the direction of the track, a ballast engaging shoe mounted vertically movably on the freely suspended support member forward end for supporting the said forward end on the ballast, pivot means substantially coaxial with the rear axle and pivotally mounting the support member rear end on the carriage for pivoting in a plane extending in the direction of the track, and at least one track clamping and lifting device mounted on the support member intermediate the ballast engaging element and rear end, lifting means for moving the forward end of said support member vertically to lift the support member forward end in relation to the ballast engaging element during lifting of the track.
  • the mobile track lifting apparatus of claim 2 further comprising a ballast tamper adjacent the track lifting device closest to the rear end.
