Description

Technical Field

[0001] The invention relates to a mobile stockpile belt having a travel unit and a conveyor unit movably connected thereto, wherein the conveyor unit has a base unit with two pillars arranged at a distance from one another, wherein a receiving area is formed between the pillars, in which a continuously circulating conveyor belt is guided at least partially, wherein the conveyor unit forms a discharge end and the delivery end in the area of the base unit, and wherein a balancing weight is arranged in the area of the delivery end. Background Art

[0002] The mobile stockpile conveyor according to the present invention is used to stack bulk materials into a stockpile. The bulk material is delivered to the stockpile conveyor in the area of the delivery end. The continuously circulating conveyor belt then transports the bulk material to the discharge end, which is located at a geodesically greater height than the delivery end. This allows the bulk material to be stacked onto the stockpile in a space-saving manner.

[0003] To achieve the greatest possible stockpile height, the stockpile conveyor according to the present invention can be provided with a conveyor unit movably connected to the travel unit. This allows the conveyor unit to be tilted relative to the travel unit. This allows the discharge end to be set at different heights. Furthermore, the stockpile conveyor can be moved by its travel unit, allowing the stockpile to be filled appropriately over a predetermined surface area.

[0004] To achieve the aforementioned functionality, the discharge end of the pile conveyor protrudes significantly beyond the chassis. To avoid mechanical instability, which could cause the pile conveyor to tilt if the discharge end is loaded with too much material, the protrusion is limited.

[0005] Increasing the chassis length can improve mechanical stability. However, this incurs additional manufacturing costs. Therefore, a longer chassis length, where the chassis protrudes further toward the delivery end, is generally disadvantageous. The resulting material cone in the pile requires more frequent movement of the mobile pile conveyor and / or limits the maximum achievable pile height.

[0006] To prevent instabilities in mobile pile conveyors, DE 26 35 969 C2 proposes the use of a counterweight that can be attached to the delivery end of the pile conveyor, if necessary. This results in additional work during operation at the construction site, which is often unacceptable and increases the risk of operating errors. The counterweight is arranged in the area of the delivery end and protrudes from the rear to generate the torque required to stabilize the pile conveyor. This protrusion limits the maximum possible adjustment angle of the pile conveyor and, therefore, the achievable material height. Summary of the Invention

[0007] The object of the present invention is to provide a high-performance windrow belt which is designed to be operator-friendly.

[0008] This object is achieved in that the balancing weight can be moved by means of an adjusting device in an adjusting movement between a first adjustment position facing the discharge end and a second adjustment position facing away from the discharge end, and the balancing weight is fixed on the outside facing away from the receiving space to one of the pillars by means of the adjusting device.

[0009] The counterweight can be moved between at least two adjustment positions by means of an adjustment device. If there is a risk of mechanical instability due to overloading of the head at the discharge end, the user can simply move the counterweight into the first adjustment position, in which it is moved in the direction of the delivery end. In the simplest case, the counterweight can be moved between only two adjustment positions, the second adjustment position forming the rest position. When the counterweight is no longer needed, for example, when the stockpile belt is being loaded for transport to the construction site, the counterweight can be moved into the rest position. Since the counterweight is fixed to the outside of the support by means of the adjustment device, the user has easy access to the counterweight and can easily move it manually. The lateral arrangement allows the stockpile belt to maintain a compact design. Furthermore, this does not affect the tilt adjustment of the conveyor unit of the stockpile belt, or only slightly.

[0010] According to a preferred variant of the invention, it can be provided that a balancing weight is attached to each of the two supports on the outside, facing away from the receiving space, by means of an adjustment device. This results in a better weight distribution. Furthermore, the balancing mass is distributed between the two balancing weights, which can be easily handled individually.

[0011] But also can make two balancing weights move by means of only an adjustment motion.For example can stipulate in this case, make the adjustment motion of two balancing weights synchronous, to simplify operation by means of synchronizing device.

[0012] A possible variant of the present invention can provide that the adjustment device comprises a guide rail, and the balancing weight can be moved relative to the guide rail between a first adjustment position and a second adjustment position by means of at least one guide element, preferably linearly, in the direction of the longitudinal extension of the guide rail. The guide rail and the at least one guide element thus form a sliding guide that allows for simple movement of the balancing weight.

[0013] In this case, it can be provided in particular that the balancing weight has a support section on which two guide elements, designed as rollers, are arranged transversely to the longitudinal extension of the guide rail and spaced apart from one another in the direction of gravity. The guide rail has roller receptacles on opposite sides, on which the rollers roll. One of the rollers supports the balancing weight in the direction of gravity. The other roller prevents it from lifting against the direction of gravity. This ensures that the balancing weight is securely fixed to the guide unit.

[0014] A simple design of the adjustment device can be achieved if the two guide rails each have at least one bend on their mutually facing sides, the bend protruding toward the longitudinal wall of the support, the two bends being connected to one another by at least one spacer, and the guide rails being connected to the longitudinal wall on the outside by means of the bend and / or the at least one spacer, in particular welded. Advantageously, the guide rails can be constructed as homogeneous parts. This reduces component and assembly costs.

[0015] A possible variant of the present invention can be designed so that the conveyor unit has a first fastening receptacle corresponding to the first adjustment position and a second fastening receptacle corresponding to the second adjustment position, the balancing weight has at least one fastening element, and the balancing weight can be fixed to the fastening receptacle transversely to the adjustment movement of the balancing weight in both adjustment positions by means of one or more fastening elements, in particular by means of a form-fitting fastening. The user can securely lock the balancing weight in the two adjustment positions by means of the fastening elements and the fastening receptacle, thereby preventing unintended movement. For example, it can be provided that the fastening receptacle is formed as a plug-in receptacle. The fastening element can be formed by a plug-in projection, for example, in the simplest case, by a bolt or screw inserted or screwed into the plug-in receptacle.

[0016] A variant of the present invention can be designed so that the adjustment device forms a hinge with a pivot axis, so that the balancing weight pivots about the pivot axis between a first adjustment position and a second adjustment position during the adjustment movement. The adjustment position can thus be changed by simply tilting the balancing weight. This device is particularly easy for the user to operate. Preferably, the pivot axis is arranged so that the balancing weight rests laterally against the support in each of the two adjustment positions, thereby achieving a space-saving design.

[0017] In the case where at least one support section is mounted on a support column, and in the first or second adjustment position the support section supports the balancing weight in the direction of gravity on the form-fitting contour, the balancing weight is additionally held in this adjustment position by the support section. This is particularly advantageous in the event of windrow belt vibrations, as this reduces the load on the adjustment device.

[0018] If the balancing weight has at least two sub-weights that are releasably connected to one another, usability and operator friendliness are further improved. For example, it can be provided that the user only needs to install one of the two sub-weights on the windrow belt to adapt it to their needs. This also makes it easier to handle the balancing weight distributed between the two sub-weights during installation and removal.

[0019] Particularly preferred is an embodiment in which the balancing weight is arranged so that in any of its adjustment positions it does not project behind the delivery end of the conveyor unit. This prevents the balancing weight from obstructing the tilt adjustment of the conveyor device in the area of the delivery end.

[0020] A preferred embodiment of the present invention provides that the base unit of the conveyor unit is connected to an extension via a pivoting or telescopic mechanism. The extension can be moved between a rest position and an operating position by means of the pivoting or telescopic mechanism. In the operating position, the extension forms the discharge end, and in the operating position, the counterweight is arranged in a first adjustment position. In the rest position, the extension can be placed against the base unit in a space-saving manner, for example, by tilting over, thereby enabling space-saving transport of the stockpile belt. In the operating position, the extension forms the discharge end, which projects outward. To prevent mechanical instability, the counterweight is introduced in the first adjustment position.

[0021] A possible variant of the present invention can be designed so that one or more balancing weights are moved by means of a servo drive, in particular a motor drive. Preferably, a sensor device and a control unit coupled thereto are provided, and when the sensor device detects a triggering operating state, the control device causes at least one balancing weight to move from a first adjustment position to a second adjustment position, or vice versa. This eliminates user errors. The triggering operating state is detected by the sensor device. This triggering operating state can, for example, be a specific adjustment position of the conveyor unit and / or a specific loading state of the conveyor unit. Once the sensor device receives a corresponding signal, the coupled control unit causes the triggering weight to move.

[0022] It is conceivable that the conveyor unit comprises a base conveyor unit and at least one sub-conveyor unit, wherein the sub-conveyor unit is movable, in particular tiltable or telescopic, relative to the base conveyor unit from a transport position into an operating position.

[0023] Possible variations of the present invention include the sub-conveyor unit being moved relative to the base conveyor unit, and the balancing weight being moved from a first adjustment position to a second adjustment position and / or from the second adjustment position to the first adjustment position. The movement can be motor-driven. It is also conceivable to provide a mechanical coupling, via which, for example, the adjustment movement of the sub-conveyor unit is transmitted to the balancing weight.

[0036] Figure 12 Shown according to Figure 11 The view in the changed runtime position. DETAILED DESCRIPTION

[0037] Figure 1 A windrow belt with a travel unit 10 is shown. The travel unit 10 has a chassis 11 which is supported by a chassis 12. The chassis 12 can be equipped with wheels or chain-type running gear on opposite sides of the chassis 11. Figure 1 In the embodiment, the traveling mechanism 12 is equipped with a chain traveling mechanism, so Figure 1 In the drawing plane, the main direction of travel is from left to right (or vice versa).

[0038] The conveying unit 20 can thus be accommodated in a movable manner by the travel unit 10. Preferably, the conveying unit 20 is coupled to the travel unit 10 by means of a first adjusting element 13 and a second adjusting element 14. The two adjusting elements 13 and 14 allow the conveying unit 20 to adjust its working inclination. Figure 1 , in which the conveyor unit 20 is oriented essentially horizontally. By adjusting the adjusting elements 13, 14, the working inclination of the conveyor unit 20 can be adjusted. Preferably, as in the illustrated embodiment, the first adjusting element 13 is arranged in front of the conveyor unit 10 in the direction of travel, and the second adjusting element 14 is arranged in the direction of travel behind the conveyor unit 10.

[0039] according to Figure 1 The conveyor unit 20 has a delivery end 20.1 and an opposite discharge end 20.2. A continuously circulating conveyor belt is assigned to the conveyor unit 20, which is not shown in the drawings for clarity. The continuously circulating conveyor belt can be used to convey bulk material delivered to the delivery end 20.1 in the transport direction to the discharge end 20.2 for stacking.

[0040] In order to simplify the loading of the continuously circulating conveyor belt, a delivery funnel 15 can be provided in the region of the delivery end 20 . 1 .

[0041] The conveyor unit 20 has a base unit 21, which is preferably connected to the chassis 11 of the conveyor unit 10 by means of adjustment elements 13, 14. The base unit 21 can be connected to an extension 28. The extension 28 can be coupled to the base unit 21 by means of a pivoting device 29. The pivoting device 29 has a drive 29.1 and a lever mechanism 29.2, on which the drive 29.1 acts.

[0042] The extension 28 can be tilted relative to the base unit 21 by means of a pivoting device 29 . Figure 2 The extension 28 is shown in the position in which it has been folded onto the base unit 21. This results in a space-saving design, so that the windrow belt can be transported, for example, on a crane truck.

[0043] Figure 1 The operating position is shown in which the lever mechanism 29 . 2 has been moved by the drive 29 . 1 , wherein the lever mechanism 29 . 2 moves the extension 28 into the folded-out position.

[0044] like Figure 1 As shown, the balancing weight 40 is movably connected to the conveying unit 20. For this purpose, the balancing weight 40 is coupled to the adjusting device 30. The adjusting device 30 enables the balancing weight 40 to be in a first adjustment position (see Figure 1 ) and the second adjustment position (see Figure 2) with an adjustment movement. In the present embodiment, the adjustment movement is performed in a translational, in particular linear, manner, which is Figure 2 This is symbolically indicated by arrows.

[0045] In the first adjustment position, the balancing weight 40 is displaced in the direction of the end on the delivery side. In the second adjustment position, the balancing weight 40 is moved relative to the first adjustment position in the direction of the discharge end 20.2, as shown in FIG. Figure 2 shown.

[0046] Figure 3 and Figure 4 The structure of the adjusting device 30 is shown. As can be seen from the schematic diagram, the adjusting device 30 has at least one guide rail 31 on which the compensating weight 40 is guided so as to be displaceable in the adjustment direction by means of a guide element 42 .

[0047] Preferably, with Figure 3 and Figure 4 The adjustment device is uniformly provided with two guide rails 31 spaced apart from one another in the direction of gravity. Both guide rails 31 have roller receptacles on their sides facing away from one another, on which guide elements 42, designed as rollers, run. At least one lower roller prevents the compensating weight 40 from being lifted off the adjustment device 30 against the direction of gravity. At least one upper roller supports the compensating weight 40 in the direction of gravity.

[0048] Preferably, the roller is provided with a profile extending in the circumferential direction so that the roller bridges both sides of the roller receptacle configured as a web. Thus, the balancing weight 40 is held fixedly on the adjusting device 30 transversely to its adjustment direction. Figure 7 This structure is shown.

[0049] The balancing weight 40 can be equipped with at least one bearing section 41 , which can be designed as a separate component.

[0050] Preferably, two support segments 41 are used, which are arranged spaced apart from one another in the adjustment direction. One or more support segments 41 are equipped with at least one guide element 42. A balancing weight 40 is connected to the support segment 41.

[0051] The balancing weight 30 preferably consists of at least two sub-weights 43.1, 43.2. In the present embodiment, each sub-weight 43.1, 43.2 is plate-shaped. Thus, the two sub-weights 43.1, 43.2 can be arranged adjacent to each other on their longitudinal sides to save space, forming the balancing weight 40. Of course, other shapes for the sub-weights 43.1, 43.2 are also conceivable.

[0052] The balancing weight 40 has at least one supporting eye 44. The balancing weight 40 can be suspended from a lifting device by means of the supporting eye 44 in order to operate the balancing weight.

[0053] It is thus possible for each counterweight sub-assembly 43.1, 43.2 to have such a bearing eyelet 44, so that the counterweight sub-assembly 43.1, 43.2 can be operated individually.

[0054] The counterweight 40 carries a handle 45 on its outer side. The counterweight 40 can be gripped at the handle and moved in the direction of the adjustment movement of the counterweight 40. This simplifies handling.

[0055] Figure 3 It is clearly visible that the guide rails 31 have bends 32. In the present embodiment, each guide rail 31 has a plurality of bends 32. The bends 32 are angled from the roller receptacles of the guide rails 31 toward the outside of the conveyor unit 20. In the region of the bends 32, the guide rails 31 can preferably be connected to spacers 33 and held parallel to each other and spaced apart. It is conceivable to connect the spacers 33 to the bends 32, in particular by welding.

[0056] Figure 5 and Figure 6 The conveyor unit 20 shown has two columns 23 arranged spaced apart from one another and connected to one another via a crossbeam 25. A receiving area is formed between the two columns 23, in which the continuously circulating conveyor belt is at least partially accommodated. Furthermore, support rollers are arranged in the receiving area and are preferably rotatably mounted on the columns 23. The support rollers serve to support the continuously circulating conveyor belt, in particular the upper conveyor section of the conveyor belt. A deflecting roller can be provided at the discharge end 20.2, which deflects the conveyor section into a lower, return idle section. For the sake of clarity, the deflecting rollers and support rollers are not shown.

[0057] Figure 7 It can be clearly seen that the upper flange 22 and / or the lower flange 24 are bent out from the support 23 in order to achieve a structural reinforcement. Figure 7 It is also shown that the adjusting device 30 is connected to the support 23 on the outside. In this case, the adjusting device 30 can be welded to the support 23. For example, the adjusting device 30 can be welded to the support 23 on the outside with its spacers 33 and / or its bends 32.

[0058] The diagram also shows that the guide rail 31 is therefore arranged at a distance from the outer side of the strut 23 , so that the guide element 42 is freely movable.

[0059] Figure 8 It is clearly visible that the balancing weight 40 has at least one fastening element 46 . Figure 6 It is shown that at least one first fastening receptacle 34 corresponding to the first adjustment position and at least one second fastening receptacle 34 corresponding to the second adjustment position are arranged on the pillar 23. In the present embodiment, two fastening receptacles 34 are respectively associated with the two adjustment positions.

[0060] If the balancing weight 30 is located Figure 5 In the second adjustment position shown, the balancing weight 40 is fixed to the second fastening receptacle 34 with its at least one fastening element 46. For example, the fastening element 46 can be a screw that is screwed into the fastening receptacle 34. It is also conceivable that the fastening element 46 forms a bolt that is inserted into the fastening receptacle 34. If one or more fastening elements 46 are loosened from the corresponding fastening receptacle 34, the balancing weight 40 can be moved along the guide rail 31 by means of the guide element 42 until the balancing weight reaches the first adjustment position. Figure 1 The first adjustment position is shown in . The compensating weight 40 can then be fastened by means of at least one fastening element 46 to at least one first fastening receptacle 34 , which first fastening receptacle corresponds to the first adjustment position.

[0061] In order to be able to clearly position the balancing weight 40 in the first adjustment position and / or the second adjustment position, it can be provided that at least one stop 35 is used, against which the balancing weight 40 hits in the corresponding adjustment position. In particular, the fastening receptacles 34 can be aligned with the corresponding fastening elements 46.

[0062] exist Figure 5 and Figure 6 It is also shown that it may be advantageous to mold the support 26, the drive unit 27 (see FIG. 2 ) in one piece on the support 23. Figure 1 and Figure 2 ) can be fixed on the bracket. The driving unit 27 is used to drive the continuously circulating conveyor belt.

[0063] Figures 9 to 12 Another variant of the present invention is shown in FIG. In this embodiment, identical components are provided with identical reference numerals, so that reference can be made to the preceding embodiments to avoid repetition. Therefore, only the differences are explained below.

[0064] As shown in the figures, the adjustment device 30 has a hinge for moving the counterweight 40. Here, the first hinge element of the hinge can be arranged on the outside of the strut 23 and the second hinge part can be arranged on the support section 41 of the counterweight 40. The two hinge parts are connected to each other via a hinge axis. Figure 11 and Figure 12 It is clear that the hinge axis is parallel to the outer side of the strut 23 and preferably also perpendicular to the longitudinal extension of the strut 23 .

[0065] The balancing weight 40 can be connected to the Figure 11 The first operating position shown in Figure 12 2. The counterweight 40 is pivoted between the first and second operating positions shown in FIG. 2 and in particular tilted relative to the support 23. In the first operating position, the counterweight 40 faces the delivery end 20.1. In the second operating position, the counterweight 40 is moved so that it faces the discharge end 20.2.

[0066] It is also conceivable that the balancing weight 40 can be adjusted by a plurality of rotations over more than a rotation length, in particular a weight length.

[0067] For example, the balancing weight 40 can be connected to the Figure 11 The first operating position shown in Figure 12 . Another hinge connection is then established on the side of the balancing weight 40 facing away from the hinge connection. This can be achieved, for example, by forming a hinge component, such as a bearing hole, on this side of the balancing weight 40, so that the bearing hole coincides with another hinge component of the base unit (e.g., support column 23). The previously established first hinge connection can then be released. The balancing weight can now be swung again about the newly established second hinge connection. It is conceivable that this reversal can be performed multiple times to appropriately adjust the balancing weight 40.

[0068] As in accordance with Figures 1 to 9 In an embodiment of the present invention, provision can again be made for the balancing weight 40 to be fixed in the respective adjustment position by means of one or more fastening elements 46 , which engage in one or more fastening receptacles 34 of the adjustment device 30 .

[0069] In the embodiment shown in the drawings, at least one balancing weight 40 can be fixed on each side of the conveying unit 20. Preferably, the balancing weight 40 is connected to the support 23 via an adjustment device 30 of the same or substantially the same structure to reduce component costs.

[0070] Figure 11 and Figure 12 In all the illustrated embodiments, the conveyor unit 20 can also have at least one support section 36, which corresponds to one of the two adjustment positions. Preferably, both adjustment positions correspond to at least one support section 36. In the corresponding adjustment position, the balancing weight 40 is supported on the support section 36 in the direction of gravity to relieve the load on the adjustment device 30.
