Description

The invention relates to a pylon for a dumping device or a combined dumping / recycling device comprising a bogie and a transfer station from or to a belt conveyor and the dumping device itself.

About a pylon takes place in a storage space device, the tension of the support cables for the boom. Known pylons for opencast mining equipment are designed as a flat structure mostly consuming as a supporting structure, since so the bearing forces of the ropes can be distributed distributed in the structure, and the pylon can also absorb bending forces in the lateral direction well. The disadvantage is a low pivoting of the opencast mining machine, due to a collision of the pylon with the belt conveyor at larger pivoting angles.

Object of the present invention is to propose a pylon for a heap bulk or combined heap bulk / Rückladegerät, which allows a larger tilt angle, and is simple and inexpensive to manufacture.

According to the invention, this object is achieved by a pylon according to claim 1 and by a dumping device or a combined dumping / recycling device according to claim 10. Preferred embodiments of the invention are the subject of dependent claims.

The pylon according to the invention can be used for a dumping device or a combined dumping / recycling device, for example a spreader. The dumping unit has a bogie and a transfer station from a belt conveyor. The pylon according to the invention has a section surrounding the boom. This is preferably a cuboid structure, the two opposite side surfaces are missing, through which the discharge belt conveyor is guided. Alternatively, a round structure or similar. possible, advantageously, a box-shaped structure is mechanically very stable and easy to produce due to its flat surfaces.

The height of the boom enclosing portion is designed so that unimpeded operation of the belt conveyor is guaranteed. According to the invention, a vertical mast section adjoins the section surrounding the boom. As a vertical mast section is understood in the context of this application, a single vertically formed structure that has only a vertically oriented carrier.

Particularly preferably, the counterweight boom is arranged on the mast section of the pylon. The counter-jib is thus firmly connected to the mast section and more preferably braced over the mast section with ropes. It is advantageous between counterweight boom and the belt conveyor enclosing section sufficient space for leading to the transfer station, conveying conveyor belt. Advantageously, due to the small width of the mast section, a significantly higher tilt angle of the dumping device or combined dumping / recycling device is possible.

A known alternative variant for increasing the pivoting angle is that the pylon has a horizontal section in the region of the boom. Thus, the pylon is placed away from the bogie in the direction of the discharge boom, which has an increase in the possible pivot angle result. The disadvantage of this solution is that the center of gravity of the device mitwandert, which requires a more massive steel construction and thus makes the device more expensive and harder.

In order to further increase the tilt angle of a dumping device with a pylon according to the invention, a horizontal region of the pylon can likewise be provided. Advantageously, the pylon according to the invention is lighter than in the prior art, so that the displacement of the center of gravity caused by the horizontal region is less consequential than in devices with pylons according to the prior art.

Advantageously, therefore, the length of the horizontal region of the pylon can be significantly reduced by the inventive design of the pylon and thus the displacement of the center of gravity. In addition, as described above, due to the lower weight of the pylon of the invention, a shift in center of gravity has less effect.

At the end of the horizontal section of the boom enclosing section connects. Advantageously, the tilt angle can be increased even further.

Further preferably, the horizontal portion is rotatably connected to a fork of the bogie. Preferably, the horizontal portion is connected to the outer portions of the belt conveyor enclosing portion. For example, the horizontal portion may also consist of two lateral supports, which then merge into the fork of the bogie or are connected thereto. Advantageously, the pivot angle can be further increased by the horizontal portion.

Preferably, the vertical mast section is a closed hollow profile. Advantageously, a closed hollow profile is easy to make, easy to commit and inspect and therefore to wait. In addition, bending forces are absorbed very well.

Particularly preferably, the vertical mast section is designed as a rectangular profile. In this case, the long side is preferably aligned in the cantilever direction. Further preferably, the long side tapers with increasing height of the mast section. Advantageously, material can be saved as the load on the mast section becomes smaller towards the top.

In addition, preferably, the counterweight boom is designed to be significantly wider than the mast section. and over laterally from the mast portion cantilevered arms is connected thereto. Advantageously, the mechanical stability of the counterweight cantilever can be improved and twisting thereof can be prevented.

An embodiment of the invention will be explained below with reference to figures. Showing:

1 a skewer according to the invention in a view obliquely from the front,

2 the same spreader in a view obliquely from behind,

3 the spreader with feed belt, and

4 a top view of the spreader with clarification of additional heap capacity.

1 and 2 show a spreader with inventive pylon. This one has a discharge boom 1 and a counterbalance boom 2 , The spreader has a bogie 3 with a fork 31 to which there is a horizontal section 4 the pylon connects. The horizontal section 4 then goes into an area surrounding the belt conveyor 5 above. The section enclosing the belt conveyor 5 is box-shaped. The inner height of the band conveyor enclosing section 5 is designed so that unimpeded operation of the belt conveyor on the discharge boom is ensured.

At the belt conveyor enclosing area 5 closes a mast section 6 at. This is formed from a closed rectangular hollow profile. On the top side has the mast section 6 a fastening for tensioning cables 61 , from which the tensioning cables for the bracing of the ejection boom 11 and for the bracing of the counterweight boom 21 depart. Between the belt conveyor enclosing area 5 and the attachment for tensioning cables 61 is the counterpart 2 at the mast section 6 attached. The attachment to the mast section 6 takes place over from the mast section 6 laterally cantilevered arms 62 at the end of a suspension 23 of the counterbalancing boom 2 seconded.

In 3 is the spreader with a conveying belt conveyor 7 shown. The conveying belt conveyor 7 leads to the transfer station 8th where the material from the conveying belt conveyor 7 on the belt conveyor of the discharge boom 1 is handed over. It is very well recognizable, as can be seen from the narrow design of the mast section 6 a significantly greater pivotability of the spreader results.

In 4 It is shown that the spreader with inventive pylon has a, compared to the standard design, larger swivel range A. This increased swivel range A of the spreader also results in an additional stockpile capacity B, as the jib can now reach more distant portions of the stockpile.
