Field of application of the invention

The invention relates to a device for dismantling and relocating complete track yokes. It is particularly applicable in mining companies, where it depends on the consideration of special superstructure conditions and other special conditions.

Characteristic of the known technical solutions

Turnout devices are known, which consist of a rail or crawler-mounted trolley and a portal-type lifting device. Before grabbing and raising the points and installing a ramp to drive the device onto the track, the transport vehicle must be driven away under the lifting device and then moved back under the lifting device for transporting the route.

The disadvantage is the corresponding time and cost for the setup process by the sicn constantly repeating repositioning of the lifter and thus required continuous process of the trolley.

Another disadvantage is the relatively high purchase cost for the entire device.

There are also construction cables for laying railway tracks with simple, robust and reliable machines, such as.

Jochverlegekrane, Gleisbai, machines and track return machines for the conversion of tracks mi! welded rails, which are used exchanged or wiadar used, known (DE-AS 1658311, DE-AS 2117791, DE-OS 2228196, DE-AS 2503197).

These are essentially complete trains, consisting of at least one gantry crane, a Rüstwagenfolge, a frame car for laying long rails and an empty car. Such machines are not suitable for use in mining companies and opencast mines due to their mass and dimensions, but only for paved track systems. Disadvantages include the high cost and operating costs.

The aforementioned solutions continue to have the common disadvantage that they can only be used for the one specific purpose of work.

By DD-PS 142068 a device for track renewal, especially of assembled turnouts or intersections in the railway is known. Here are two facing each other with their arms railway cranes, between which a turnout and crossings adapted Wendetraverse is arranged, used.

The disadvantage here is that this device is unsuitable for use in opencast mining by the two-crane operation, requires larger acquisition and operating costs and a higher set-up and assembly time.

Object of the invention

The aim of the invention is to provide a device for the conversion of track systems, especially in opencast mines, through which a high productivity, with a minimum set-up effort and low acquisition and operating costs, is achieved.

Explanation of the essence of the invention

The invention has for its object to provide a device by which the Gloisumbau under special top conditions, which are particularly found in opencast mining, is possible. In this case, track-laying machines that can only be used for the specific purpose of work should be avoided.

The object is achieved in that the device consists nus a mobile boom crane with a rotatably mounted load crossmember. The suspension point of the load spreader is slidably disposed to achieve a horizontal position of the spreader with a load unbalanced load. At the ends of the longitudinal member of the load traverse, transverse bars are arranged with rail clamps, perpendicular to the longitudinal direction. Between the rail clamps of a cross member, a rod is arranged in each case, at the ends of which centering sensors are mounted for threading into the track. According to the invention, supporting arms are fastened to the long girder of the load crossmember, whose supporting cylinders with the supporting plates are adjustable independently of one another and differently in extension and retraction dimensions. The cross members are arranged verschleblich in their longitudinal direction. For this purpose, a sliding track and sliders are arranged in each cross member hydraulic or pneumatic working cylinder and between the cross members and the longitudinal beam of the load traverse. In this case, the cross member are each tiltably mounted to take account of track overshoot on a arranged on the long beam dome.

Ausführungsbeisplel

In the drawing, an expedient embodiment of the invention is shown and indeed show

Fig. 1: an illustration of the jib crane with load spreader and hinged track yoke Fig. 2: a side view of the load crossmember

Fig. 3: a plan view of the load crossmember

Fig. 5: section of Figure 4 along the line A-A.

The device consists of Fig. 1 from a mobile jib crane ¹ with a rotatably mounted load crossmember 2, doren suspension point is slidably mounted. According to Figure 4 and 5, transverse bars 4 are arranged at the ends of the load cross-member 2 at right angles to the longitudinal direction, on which rail tongs 5 are articulated. Between the rail tongs 5 each telescopic, jine rod 6 is arranged, are attached to the ends of centering sensor 7. According to FIGS. 2 and 3, support arms 8 with supporting cylinders 9 and support plates 10 are fastened to the longitudinal members 3 of the load cross-piece 2. The cross member 4 are arranged displaceably in their longitudinal direction. For this mobility 4 slideways 11 and sliders 12 are arranged according to Figure 4,5 between the longitudinal member 3 of the load cross member 2 and the cross members. The cross member 4 are arranged tiltably on a cap 13.

When lowering the load bar 2 on the track, the rods 6 lie on the rails.

By attached to the telescoping rods 6 Zentrierfühler 7 and the mobility of the rail clamps 5, the cross member 4 adapt to the track. The open rail tongs! *! 5, the cross members 4 and the rods 6 are connected by means of detents 14. The assemblies 14 are released, whereby the rail tongs 5 close after a vertical movement of the crane stroke and grip the rails. The support arms 8 are swiveled out laterally and the support cylinders 9 are extended to the traction of the support plates 10. The further single or reciprocal lifting movement of the support cylinders 9, whereby the hoisting rope is pulled continuously taut, lifts the track yoke 15 out of the track bed are retracted and brought the track yoke 15 by the crane stroke in the required lifting height after the center of gravity has been corrected so that the load crossbar 2 hangs with the attached track yoke 15 in a horizontal position Gleisjoch 15 brought over the new track bed In the load cross-member 2 on the extended support cylinder 9, the attached track yoke 15 is positioned on an already laid track piece, wherein a required track bearing correction is carried out by the transverse displacement of the cross member 4 by means of the working cylinder 16. Thereafter, the support cylinders 9 are retracted and the track yoke 15 is deposited on the new track bed. The placement of the rod 6 causes the opening of the Schie'.fcnzangen 5. Thereafter, the lock 14 is re-inserted and thereby secured the rail clamps 5 in their open state.

The inventive solution can be used in particular for the track renewal in opencast mines. There are the particular advantages of a significant reduction in acquisition costs and a minimization of operating costs. Wherein the jib crane for further operations z. B. emergency use, is used.
