Bridge scraper with lifting and moving device

The present invention relates to a bridge scraper with a lifting and Umsetζvorrichtung, as well as one that spans the width of the pile rail-bound longitudinally movable bridge and on this transversely to the heap arranged vertically running bulk goods Takeaway direction, such as scraper chain, load cell chain or the like. for changing locations or moving from one heap to another, with running rails arranged parallel to one another in the longitudinal direction and a transverse carriageway that can be connected to them.

Known devices are either provided with sliding platforms that are self-propelled - this is expensive and complicated when moving, or the moving device is arranged on the device itself, in which the subframe is raised and is moved in the new direction. This assumes that both chassis beams have the same wheel spacing, thus a relatively precise manufacture of the device is required. This is also time-consuming and cumbersome in the Procedure.

The invention is based on the object of significantly simplifying the transfer device, an economically more advantageous one Provide a solution and significantly shorten dead times in process engineering. It is the aim of the invention to design the bridge scraper in such a way that it can move from one pile to the other with its speed of changing places without interruption can drive.

The device is stored in the starting position between two heaps, For example, one heap is ready for dismantling and the other is to be built.

After one heap has been dismantled, the device must be brought to the new heap or moved as quickly as possible. This was so far associated with a great deal of time and performance loss for the subsequent processing. It's another goal the invention to keep the performance degradation to a minimum.

According to the invention, this object is achieved in that at least one side of the bridge at an end section of this one on a longitudinal Sch.lene movable pendulum support with a Lifting device is arranged over which the entire bridge including the scraper chain is raised to a predetermined height and pivoted into a transverse track that one end section the bridge formed with a fixed side and the other end portion of the bridge with a loosely guided side is that the fixed side has horizontal guide rollers that engage the longitudinal rails of the bridge scraper, and vertical rollers, but the loosely guided side only has vertical rollers that the wheel spacings the horizontal guide rollers and the vertical rollers on the fixed side are much larger than that of the loosely guided side or side of the pendulum support and that for moving in another direction or for transverse movement of the scraper device, the distance between the rails of the transverse carriageway intended for repositioning is the same as the wheel distance on the loose one led page is.

It has proven to be advantageous that at a distance between the rails of the transverse carriageway on a head carrier of the fixed Side vertically pivotable wheels are arranged, which are used to lift the bridge scraper, over a lifting device lifted the device, pivoted and over the vertical rollers are set down in the cross carriageway.

A variant of the invention provides that the intersections of the longitudinal rails and the transverse track with turntables for Recording of the device when moving are formed.

The invention is described in the following description of an in the embodiment illustrated in the drawing explained in more detail.

Show it:

Fig. 1 the device in plan view,

Fig. 2 is a section taken through the plane A-A of Figs

FIG. 3 is a section taken through plane B-B of FIG. 1.

It is a bridge scraper that can be moved to the stockpile on longitudinal rails 13 6 provided with a bridge 1 and a scraper chain 7 or the like. Is provided. On one end section of the bridge there is a fixed side 2, on the other end section there is a loosely guided side 3 arranged.

The firmly guided side 2 is equipped with horizontal guide rollers 4, which engage the longitudinal rails 13 of the bridge scraper, to derive the horizontal forces, as well as vertical rollers 5, the loosely guided side only with vertical ones Rollers 5 provided.

On the section of the bridge 1 with the loosely guided side 3, there is one on the longitudinal rail 13 at the end section of the bridge 1 movable pendulum support 8 arranged with a lifting device over which the entire bridge 1 including the scraper chain 7 is raised to a predetermined height and converted into a transverse track 9, the rail spacing of the for the transfer provided transverse carriageway 9, the two parallel Rails includes, equal to the wheel spacing on the loosely guided side 3, while the wheel spacing of the horizontal Guide rollers 4 and the vertical rollers 5 on the fixed side 2 is much larger than that on the loosely guided side 3 or side of the pendulum support 8. Opposite the fixed side 2 is the loosely guided side 3 articulated to the pendulum support 8. At the distance of the rails of the transverse track 9 are on a head support 10 of the fixed side 2 vertically pivotable arranged upper running wheels 11, which are used to lift the bridge scraper 6 serve. The bridge scraper 6 is raised by a hydraulic or similar device and placed on the transverse track 9 offset.

On the side of the pendulum support 8, the vertical running wheels 5 can be pivoted horizontally in a second head carrier 12 educated.

The intersection of the longitudinal rails 13 and the transverse track 9 are with turntables 14 to accommodate the device when moving educated.

The drive for the transverse movement takes place via the chassis motors the pendulum support side.

The way it works is as follows:

The bridge scraper, which can be moved on the longitudinal rails before moving from the actual work area to a parking or transfer position in the end section of the longitudinal rails proceed, with the four intersection points of the longitudinal and transverse rails, which act as turntables, for transferring to the transverse carriageway

are equipped with rail sections, serve. To Moving into the parking position, the pendulum support side is raised and the drives are in the new direction of travel implemented. Then the pearl support side with the vertical rollers for the pendulum support side and the fixed side lowered onto the transverse track, the trolleys on the fixed side are released or break away from the longitudinal carriageway.

This means that the device can be moved in the new transverse direction.
