Description

DETAILED DESCRIPTION OF THE INVENTION The present invention comprises at least one steep conveyor, the steep conveyor having a feed trough and a return trough between the storage leg and the drive head; and this steeply inclined conveyor carries a jib conveyor and is pivotally connected to a jib which can be swung in a vertical plane, in which case it is arranged transversely and horizontally to this jib and has a drive part. such that the steep conveyor can swing at a significant angle about a first swing curve spaced below the head, and in a direction non-intersecting to the jib and a first swing curve. The jib conveyor is configured to be able to swing about a second swing axis that is perpendicular to the first swing axis; The present invention relates to a conveyor device, wherein the device is configured to supply a jib conveyor with a flow of material that is transported over the entire oscillation range of the steep conveyor.

Conveyor devices of the above type have already been known for a long time. Applicant's German Patent Publication no.
No. 2018120 discloses ship or container unloading equipment. This unloading installation has two steeply inclined conveyors designed as trough chain conveyors, which are pivotally connected to the tilting jib of the crane position and whose trough axis is aligned by means of a hydraulic piston-cylinder unit. It is possible to swing around the link shaft within the feed plane determined by . The incoming material is fed via a transfer device projecting laterally of the feed plane to a jib conveyor which carries out a further feed movement. This transfer device consists of two transverse boxes with a common hopper that connects both trough chain conveyors to each other and transitions into the drop tube. The fall tube is connected at the link shaft to a jib conveyor, which has two feed boxes designed for the purpose. In this device, the steeply inclined conveyor can only swing in one plane;
Unloading equipment is complex and expensive.

In such an arrangement, the forces exerted on the conveyor laterally during operation create large tensions in the conveyor and jib.

Conveyor systems are also known in which a steeply inclined conveyor is arranged to be able to pivot relative to the jib in two mutually perpendicular planes. In such a conveyor system as disclosed in U.S. Pat. No. 3,640,376, the steeply inclined conveyor rotates both of its troughs about the first pivot axis, the axis of rotation of the upper drive chain wheel. It is provided so as to be swingable within the feed plane determined by the axis. Furthermore,
The steep conveyor is pivotably jib-mounted about a second axis to permit lateral rocking movement from a vertically central position on the conveyor's feed plane. However, this device is relatively complex and is not suitable for many uses.

Furthermore, this conveyor is designed as a bucket conveyor and requires an additional conveyor belt to unload and deposit the incoming material onto the jib conveyor. The transfer of material from the steep conveyor to the jib conveyor is therefore extremely complex. Furthermore, continuous material transfer during the oscillating movement of the conveyor is difficult.

The object of the invention is to enable, in a conveyor installation of the type mentioned at the outset, an oscillating movement of the steeply inclined conveyor in any direction by pivoting the steeply inclined conveyor to the jib conveyor in a new and simple manner; Accordingly, the scope of application should be expanded, and at the same time, the structure should be such that it does not interfere with the delivery of the material being sent to the jib conveyor.

With the above configuration of the invention, it is easily possible to provide a second oscillating axis between both troughs, with the center of gravity of the steeply inclined conveyor being vertically below this oscillating axis. No equipment is required to hold the conveyor in a vertical position. This also makes it possible to suspend the steeply inclined conveyor so that it can move freely around the second swing axis, so that even if an impact occurs when the conveyor is below the steeply inclined conveyor, the is guided only into a oscillating movement about the second oscillating axis and has no detrimental effect on the movement of the jib. Torsional stresses in the jib and bending stresses on the sides of the steep conveyor are thus avoided.

The features of the feeding device to solve the above problems are that the feeding trough and the return trough are configured to form a feeding surface parallel to the jib, and the unloading device is the steeply inclined conveyor is configured to deliver a flow of material from the feed face of the feed trough at the side of the feed trough, and the steeply inclined conveyor has a free lateral rocking movement about a second rocking axis; This means that the jib is equipped with a

An advantage of the invention is that it allows rocking in any direction of the steeply inclined conveyor and that the single
A simple structure is obtained that can be applied to one or two steeply inclined conveyors. In order to reach the material over the entire width of the ship, the possibility of oscillation in the feed plane is important. The possibility of rocking in the lateral plane is of particular importance. This is because this rockability avoids the transmission of torsional forces to the jib. This essential advantage means that the jib is significantly lighter and its role is fulfilled without any loss of function. Of course, it is not necessary to limit the relative movement caused by the suspension mechanism between the lateral removal device and the material inlet box. However, the difficulty caused by this is that the two
This is overcome by the construction of the delivery device with two parts, in which case the transfer of the material stream into the material inlet box is not obstructed. It is also possible in some circumstances to transport the material from an inaccessible location on a ship or tank installation by swinging to the side of the feed face of a steeply inclined conveyor.

According to a first embodiment of the invention, the link device is designed as a ball joint between the two troughs. This embodiment allows not only a swinging of the conveyor in the feed plane or the transverse plane, but also possibly a pivoting of the conveyor about its longitudinal axis.

A particularly advantageous embodiment of the invention is characterized in that the linkage is a Cardanian suspension, in which case the first pivot axis and the second pivot axis are the links of the Cardanian suspension. It is an axis and exists within a plane. In this case, the first link shaft is in particular two central pins which are rotatably mounted in the bearing of the jib, and the second link shaft passes between the two central pins and is rotatably mounted in the bearing of the trough. It is designed as a bearing-mounted rotary shaft.

Advantageously, both link shafts are fixedly provided in the intermediate frame. The intermediate frame, center pin and rotating shaft form a Cardan-style suspension mechanism provided between the troughs. Advantageously, this suspension mechanism is arranged symmetrically with respect to the trough. With this configuration, the available space is fully utilized and the structure is correspondingly strengthened.

The configuration described above makes it possible to achieve the intended function in a simple and practical manner and with low construction costs.

In the configuration according to the invention, even if the steeply inclined conveyor makes a swinging movement, the unloading device of this steeply inclined conveyor is provided on the side of the feeding surface,
This ensures that the material is transferred to the jib conveyor without hindrance, even if the device has to be moved at least partially relative to the material inlet box of the jib conveyor during the oscillating movement of the steeply inclined conveyor. Such a discharging device advantageously has two parts which are movable relative to each other and which are integral with the discharging hopper connected to the conveyor trough and which extend upwardly in the direction of the material flow. and a lower part in the downstream direction of the material flow, which opens into the material inlet box.

The opening into the substance inflow box of the lower part is preferably coaxial with the first oscillation axis. This material inlet box is preferably arranged at the level of the first oscillating axis in accordance with the arrangement known from DE 2018120 A1. In this case, the outflow part is essentially immovably connected to the material inlet box in the axial direction of the first oscillating axis and rotates about this oscillating axis relative to the material inlet box. It is set up so that it can be moved. When the steep conveyor is oscillated about the first oscillating axis, there is no relative movement between the upper part and the lower part, but only a pivoting movement of the lower part relative to the material inlet box.

This relative rotational movement can be easily sealed in the manner of a tongue-like seal. Therefore, neither dirt nor substances can escape through the rotating connection. of course,
A certain degree of reciprocating movement of the lower part relative to the material inlet box is possible by means of an oscillatory movement. However, such movements are not hindered in any way by the design of the tongue in the manner of a joint according to the invention.

A relative movement between the upper part and the lower part of the removal device is advantageously possible by means of a telescopic connection of these parts. This connection is provided in the area of the removal device that is closest to the second pivot axis. This results in a very slight telescopic movement when the steeply inclined conveyor performs a oscillating movement about the oscillating axis.

The above-mentioned features enable the steep conveyor to be swung in multiple directions without interrupting the connection between the discharge device and the material inlet box and the accompanying flow of material.

The telescoping end of the above-mentioned part of the removal device can be formed in a curved manner, so that the telescoping movement takes place along an annular trajectory, the center point of which is aligned with the second pivot axis. exists on the line. The telescoping movement is therefore carried out in an optimal manner.

One or more seals extend between the mutually movable parts and are rigidly connected to these parts.

According to a particularly advantageous embodiment of the invention, the movable joint is surrounded by a seal which is integrally connected to both the upper part and the lower part. This makes it possible to feed the bulk material into the inlet box of the transport device without dust.

Due to a particularly advantageous configuration of the removal device, the flat end face facing the upper part of the lower part is oriented radially relative to the second pivot axis, and is It is installed vertically. This configuration allows a greater range of swing between the upper and lower parts.

The invention will be explained in more detail below with reference to embodiments illustrated in the accompanying drawings.

In FIGS. 1, 2 and 2A, a steeply inclined conveyor 1 is installed in two troughs of a jib 2 with a material inlet box 4 provided above the jib 2. In FIGS. The steep conveyor 1 comprises a drive wheel 8 rotatably journaled in a feed trough 5, a return trough 6 and a drive head 7. This drive wheel is driven by a hydraulic motor 9 via a transmission 10 and guides the feed chain from the feed trough 5 to the return trough 6. The axes 12 of both troughs 5, 6 define a feed plane 13 whose central position coincides with the plane of symmetry of the jib 2.
In FIG. 2, the drive head 7 projects laterally relative to the feed surface 13 and is partitioned by a side wall 14 running in the form of a hopper.
5 and an unloading device 16 connected thereto and opening into the substance inlet box 4. The substance inflow box 4 has an annular inflow hole 17, which is provided coaxially with the swing axis 18 at the height of the swing axis 18.

The steep conveyor 1 is pivotally connected to the jib 2 via a linkage in the form of a cardanian suspension. Illustrated in detail in FIGS. 3 and 4,
This suspension mechanism, which will be described in more detail below, allows the steep conveyor to be moved via a first link shaft 20 to a second oscillating conveyor running in the feed plane 13 about its oscillating axis 18 and perpendicular to the oscillating axis 18. Via the motion axis 22 it is pivotable in a transverse plane perpendicular to the feed plane 13. The first link shaft 20 is horizontally oriented and rotatably supported in a bearing 23 of the jib 2. The second link axis 21 is oriented perpendicularly to the first link axis 20 and the troughs 5, 6
These troughs are supported in bearings 24 between them.

The unloading device 16 has an upper part 25 which is integrally connected to the unloading hopper 15 and a lower part 26 which is remote from this upper part and opens into the material inlet box 4 on the side of the link shafts 20, 21. are doing. This lower part is firmly connected to the first link shaft 20 on the side facing the first link shaft 20;
At its end, it is pivotable about a pivot axis 18 within the hole 17 of the substance inlet box 4, but is provided immovably in the axial direction. The upper part 25 has a steeply inclined angle with respect to the feed surface 13, and the lower part has a slightly inclined angle. The parts 25, 26 are arranged to be movable relative to each other. In other words, the upper part 25 carries out a reciprocating sliding movement within the lower part 26 in correspondence with the rocking movement about the rocking axis 22. Upper part 25 and lower part 26
The connection therebetween is designed as a telescopic connection and is provided in the region of the removal device 16 closest to the second link axis. As can be clearly seen in particular from FIG. This is carried out along an annular locus that exists above the swing axis 22 of. Due to the ease of such relative movement, the shapes of the parts that move relative to each other can be simple, and the gaps between these parts can be easily sealed. The outlet end 36 of the upper part 25 or the inlet opening in the lower part 26 is of substantially square cross-section. It is advantageous to form the inlet opening in this way squarely. This is because the ends can be formed in such a way that they can be telescoped, and only a small gap is required between the two telescopic parts, so that the delivery of the material to be transported is energy efficient. This is because it is carried out without any loss and under dust-proof conditions. Only a small amount of play is required on the sides. This is because the lower part is rotatably mounted within the substance inlet box. Also, there is only slight play in the upward and downward directions. This is because the inlet opening is arranged radially relative to the second pivot axis. Therefore, neither substances nor dust can easily escape. Inflow opening 3 in the lower part
8 is formed in particular by a plate 37. In this case, the plate must have a circular outer circumference and a square opening 38. The lower part 26 may correspondingly be circular in cross-section. This movable joint 27
The packing joint 28 surrounding both parts 25, 2
6 and enables the feeding of the incoming material to the material inflow box 4 without generating dust. Possible coupling configurations between the lower part 26 and the material inlet box 4 can be seen in FIGS. 5A, 5B and 5C.

According to FIGS. 3 and 4, the Cardan-style suspension 19 has a frame 29 with two bearing journals 30 oriented in its longitudinal direction and rotatably mounted in bearings 23 of the jib 2. It is equipped with These bearing journals are connected to the first link shaft 2
0 and determines the first swing axis 18. Transversely between the central pins 30 is a rotary shaft which serves as a second link shaft 21 and is fixed relative to the frame 29 and rotatably supported in bearings 24 of the troughs 5, 6. 31 is running. The second link shaft 21 defines a second pivot axis 22 which, together with the first pivot shaft 18, lies in a plane transverse to the feed plane. .

When the steeply inclined conveyor 1 is swung in the feed plane 13 by the swiveling cylinder 32, the unloading device 16 is swung together, the lower part 26 being in the inlet hole 17.
It is possible to rotate unhindered about the pivot axis 18 within the holder. As shown in FIG. 1, the swing lever may have any configuration, although it is limited by the stroke length of the swing cylinder 32.

If such an excursion about the oscillation axis 22 in a lateral plane perpendicular to the feed plane 13 occurs, the suspension of the steeply inclined conveyor allows a lateral excursion of this conveyor; The oscillating axis 22 avoids the transmission of shocks occurring during operation to the jib. The lower part 26 remains fixed, but the upper part 25 swings with the conveyor 1 and the lower part 2
6. This sliding movement is possible via a telescopic connection 27 of the two parts 25,26. Of course, the steeply inclined conveyor 1 can swing in any direction about the two swing axes 18, 22. However, in this case both parts 25,2
No dissociation or tightening of the 6 bonds or interruption of the flow of the incoming material occurs.

Figures 5 and 5A show details of the superior delivery device. The steeply inclined conveyor of the construction according to FIG. 5 corresponds to the construction according to FIGS. 1 to 4 and is carried by the jib 2 via a Cardan-style suspension mechanism provided between the troughs. Unloading device 16'
Similarly, an upper part 25' which is firmly connected to the discharge hopper 15 and a separate side of the link shafts 20, 21 opening into the substance inlet box 4 and moving with the upper part 25 are provided. and a lower portion 26' which is possibly connected to the lower portion 26'. This lower part 26' is rigidly connected to the first link shaft 20 and at its outlet end opens into the inlet hole 17' of the material inlet box 4.
It is arranged so that it can rotate in rotation about the first pivot axis 18 and, on the contrary, cannot move in the axial direction. When the steep conveyor 1 is in a vertical position, the steepness of the lower part 26' corresponds to the steepness of the upper part 25'. Connection 27' designed as a telescopic connection and movable
is provided in the region closest to the second swing axis 22 of the unloading device 16'. End face 3 of the lower part 26' facing the upper part 25'
0 is oriented radially to the second pivot axis 22 and perpendicularly to the direction of inclination of the sections 25' and 26'. This feature results in a minimal movement of the upper part 25' when the steeply inclined conveyor 1 is oscillated about the second oscillating axis 22.

The coupling 27' according to this embodiment is constructed somewhat more simply than the construction described in connection with the first embodiment. In the illustrated configuration, there is sufficient play between the upper part 25' and the opening 38' in the plate 37' of the lower part 26', so that a movability of both parts is achieved. In this embodiment, the upper part 2
Both 5' and the lower part 26' are circular in cross section. If, due to the properties of the material and the size of the play space, too much dust has accumulated in the packing joint surrounding the movable joint, the arrangement according to FIG. 2A can be applied.

The packing joint 28 is a movable joint 27'
It surrounds and is rigidly connected to parts 25' and 26'. This packing joint protects the joint 27' from the outside and allows a dust-free feeding of the incoming material into the material inlet box 4.

FIG. 5A illustrates a rubber tongue fitting 39 in the form of an annular joint. It is located between the lower part 28' and the material inlet box 4. This seal is fixed to the flange 41 delimiting the inflow opening 17, for example by means of a belt 42 and screws 43, and has an annular contact surface 44. This annular contact surface lightly abuts the flange portion 45 of the lower portion 26'. The lower part can carry out rotational movements as well as slight axial sliding movements relative to the material inlet box. However, in this case, Patsukin 3
The sealing effect of 9 is not impaired. 5B and 5C show a further sealing possibility with a particularly simple tongue seal. This tongue-like packing can be made by stamping from flat material and therefore at a more cost-effective price compared to already formed packings, and can be made using loose rings or It is economical because it can be fixed in an annular groove.

Other embodiments of the invention are also possible. It is possible to provide the steep conveyor 1 symmetrically with respect to the jib 2. Two steep conveyors can be provided. The linkage does not necessarily have to be a Cardan-style suspension 19 arrangement. For example, it may be designed as a ball joint or as two link shafts that are designed as rotating shafts consisting of one part running in different planes.
It is also possible for the movable connection 27 between the two parts 25, 26 to be a connection, for example in the form of a buckle structure. Other arrangements are easily possible, in which the removal device is constructed from two or more parts that are movable relative to each other, possibly using a number of gaskets.
