Definitions
- the present invention relates to a ballast tamper for a railway track, including at least one vertically movable frame and on which are mounted tools vibrating under the action of a vibrator and controlled to effect a work stroke corresponding to their approach towards and their movement away from a sleeper, and also controlled so as to be raised into a withdrawn position within the railway gauge.
- the tools of which, provided with picks, are fixed to rigid tool-holders, in the shape of levers hinged on two pivots, the one connected by a rod to the eccentric of a shaft rotating on a vertically movable frame, the other pivot sliding horizontally on this frame either by a hydraulic jack, or by a screw-nut assembly actuated by a motor.
- the said movable frame comprises pairs of toolholders which face each other on either side of the eccentric shaft, that is to say of the sleeper to be tamped, these pairs of tool-holders being disposed on each side of the line of rails.
- the connecting rods remain substantially horizontal and the tool-holders, vertical in the mean position, can be but very slightly inclined due to the small stroke tolerable [for the sliding of the pivot.
- the small stroke tolerable for the sliding of the pivot.
- a first difiiculty presents itself when tamping the double sleepers which are disposed at the rail ends.
- the limited opening of the pair of tools has for result that the picks grip less ballast than normally, especially when the sleepers are slightly separated.
- the tamping carried out is thus less good at one point where on the contrary it should be better. In order to overcome this, it is then necessary to repeat the tamping cycle, from which considerable loss of time.
- the present invention aims as it happens at providing a tamper which allies these advantages and which is characterized in that each tool is integral with a first rigid member hinged at two different points, respectively on a second rigid member and on one of the elements of an individual control jack, this jack bein-g itself also hinged, by its. other element, to the second rigid member, the three hinge points forming a triangle deformable solely under the action of the jack, to ensure the work stroke of the tools and the raising of the latter into a withdrawn position, and inversely, this triangle being mechanically connected to the vibrator so :as to be vibrate-d,
- FIG. 1 shows a side view thereof, with partial sections, of a first embodiment with eccentric vibrator and cylinder and piston hydraulic jack.
- FIG. 2 is a section along 2-2 of FIG. 1.
- FIG. 3 is a side view thereof, with partial sections, of a second embodiment showing the use of a screw jack, with motor, as well as another method of fixing the toolholder on the frame.
- FIG. 4 is a section along 4-4 of FIG. 3.
- FIG. 5 is a general lateral view of a tamping vehicle equipped with the said first embodiment of the tamper.
- FIG. 6 is a side view thereof, with partial sections, of a third embodiment including two simplified tool-holders, with dynamic balancing, disposed side by side, and vibrating in synchronism through the action of an eccentric.
- FIG. 7 is a front view thereof with sections along 7-7 of FIG. 6.
- FIG. 8 shows, in side view, with partial sections, a fourth embodiment including two tool-holders, with inner dynamic balancing, disposed face to face and vibrating in synchronism under the action of an unbalanced element.
- FIG. 1 one sees a tool-holder including a lever 1 hinged at 2 .to a double lever 3,'itself hinged at 4 to the rod 5 of a piston 6 sliding in a cylinder 7 the head of which is hinged at 8 in the fork 9 of the lever 1.
- the double lever 3 pivots at 15 between two walls 16 constituting a frame sliding, by meansof its vertical guide 17 of rectangular section, along a column 18 carried by the front part of a railway vehicle shown in FIG. 5.
- the said movable frame carries an eccentric shaft 19 coupled by a connecting rod 20 pivoting at its end between the sides of the double lever.
- Each tool istherefore integral with a first rigid memher 1, hinged at two different points, on the one hand at 2 to a second rigid member 3, and on the other hand, at 8 to the element 7 of the jack 5, 6, 7.
- This jack is itself hinged at 4, by its other member 5, to the second rigid member 3.
- the three hinge points 2, 4, 8 form a triangle deformable solely under the action of the jack 5, 6, 7.
- the jack occasions, by the relative movement of its members, on the one hand, the closing and opening stroke of the tools and, on the other hand, the raising of the latter into a withdrawn position within the railway gauge, as will be explained in detail a little further on.
- the triangle 2, 4, '8 is connected mechanically to the vibrator by the connecting rod 20, to be vibrated. It is connected to the movable frame 16 by a connection authorizing this vibration, that is to say the connecting rod 20 and the hinge 15.
- the control of the jacks being indi- 4. obstacles (switches, oblique sleepers, double sleepers, gullies, track apparatus, et-c.).
- the rotating shaft 19 causes the tool-holder to oscillate about 15, due to the oil enclosed in the chambers 22 and 23, which causes the pick 11 to vibrate in a vertical plane and towards the sleeper 13 in service.
- hinges 2, 4 and 8 of the toolholder do not pivot about themselves under the effect of the vibrations, but solely under the action of the jack, important advantage from the point of view of lubrication and wear.
- FIG. 2 reproduoeswith the same designationsa part of the elements shown'in FIG. 1.
- FIGS. 3 and 4 show-with the same references to facilitate the understandingelements of FIGS. 1 and 2.
- the jack is here constituted by the screw 25 which the pivot 8 prevents from rotating about itself and by the nut 26 integral with a toothed wheel 27 gearing with the pinion 28 of the motor 29.
- the latter is fixed to the element 30 which forms at 31 a bearing for the cited nut 26, and is provided with pivots 32 and 33 to produce the preceding hinge 4.
- the tool-holder is hinged at 15 by its pick lever 1, which is of advantage for the solidity of the mechanism.
- the screw-nut system being irreversible, the tool-holder vibrates as a whole and as previously about 15.
- FIGS. 6 and 7 again reproduce-with the same referencesmost of the elements of FIGS. 1 and 2.
- FIG. 7 one sees a particularly favourable arrangement of two tool-holders set out side by side, each of the cylinders being shown in section and swung horizontally for a greater clearness of the drawing.
- FIG. 7 shows first of all that each cited cylinder 7 has two pivots 34 and 35 to form the hinge 4.
- each of the levers 1 is pivoted on a tube 36 welded to the lever 3 to produce the preceding hinge 2.
- This tube in its turn pivots on a shaft 37 integral with the walls 16 of the movable frame so as to form the hinge 15 concentrically with 2.
- FIG. 8 one seeswith the same designations two tool-holders of the last described type and of which the double levers 3 of the preceding examples are merged to form the double walls of a vibrating frame 42 under the action of an unbalanced element kept 39 in rotation.
- the elements 40 and 41 connect this vibrating frame to the vertically movable frame 16.
- the tool-holder according to the inventionor any other variant issuing therefromis of a very general use and permits any group of combinations of opposed and/or parallel picks on a same frame, driven for example by a common vibrator, combinations which a man of the art may easily imagine as following the aim to be attained, for example a universal tamper.
- a ballast tamper for a railway track including at least one vertically movable frame and on which are mounted tools vibrating under the action of a vibrator and controlled to effect a'work stroke corresponding to their approach towards and their movement away from a sleeper, and also controlled to be raised to a withdrawn position within the gauge of the railway, wherein each tool is integral with a first rigid member hinged at two different points, respectively on a second rigid member and on one of the elements of a jack with individual control, this jack being itself also hinged, by its other element, to the second rigid member, the three hinge points forming a triangle solely deformable under the action of the jack, to ensure the work stroke of the tools and the raising of the latter to a withdrawn position, and inversely, this triangle being mechanically connected to the vibrator to be vibrated, and being moveover connected to the movable frame by a connection authorizing this vibration.
- a tamper according to claim 1 wherein the vibrator is connected to the above mentioned triangle by a connection disposed between this vibrator and the second rigid member.
- connection between the triangle and the movable frame includes a pivot of one of the said rigid members on the movable frame.
- connection between the triangle and the movable frame includes a pivot of one of the said rigid members on the movable frame, the pivot of the two rigid members one on the other and the pivot of one of them on the movable frame being coaxial.
- a tamper according to claim 1 wherein the hinge of the jack on the second rigid member is at a position along the length of this jack, in order to improve the inner dynamic balancing of the system.
