Definitions

  • the invention relates to a locking device for a displaceable bunker wall, with a support arm that can be pivoted between a transport and an operating position, which supports the bunker wall on a base in the operating position, and a locking element that can be displaced along a fixing direction for positively locking the support arm in the operating position.
  • Various mobile machines for processing bulk material such as crushers or screening machines, are known from the prior art, in which the bulk material is fed to a bunker with a bunker wall and a base before or after its processing.
  • the bunker walls are displaceably arranged on the base, so that a choice can be made between a compact transport position and an expansive operating position in which the bunker walls are arranged, for example, in a funnel shape.
  • securing tabs are known for the support arm, with a wedge being positively driven into the securing tab to fix the support arm in the operating position.
  • the disadvantage of the prior art is that the insertion of the wedge into the securing tab for fixing the support arm is questionable in terms of operational safety, since the wedge is pressed against the weight of the bunker wall and the support arm manually with great effort, for example by hammering, from above must be driven into the safety tab. Further
  • the securing tab itself is only accessible in the operating position if the relative positions of the support arm with the securing tab, base and bunker wall are precisely coordinated with one another, so that manufacturing tolerances of the mobile machines must be kept extremely small.
  • the invention is therefore based on the object of establishing the operating position with only little effort, although high forces have to be introduced into the support arm and at the same time enabling a high manufacturing tolerance of the components involved with high operational reliability.
  • the invention solves the problem in that the locking element is mounted on the base or the bunker wall and the fixing direction runs parallel to the pivot axis of the length-adjustable support arm.
  • the force required to produce the positive connection does not have to be applied against the weight force of the bunker wall and the support arm to be derived, since the fixing direction runs essentially transversely to the weight force vector.
  • the forces to be dissipated only act on the locking element when the operating position is reached.
  • the form fit which absorbs high forces, can be produced by applying relatively small forces.
  • the support arm is designed to be adjustable in length, so that even with any manufacturing tolerances, the support arm and locking element can be aligned to produce the positive connection without undesirable transverse forces.
  • the locking element is preferably elongated and runs in the fixing direction. Alignment means that the relative position between the locking element and the support arm is changed in such a way that the locking element can again produce the positive connection according to the invention when shifted in the fixing direction, without components hindering the displacement of the locking element.
  • This alignability also enables the locking element to be mounted on the base or on the bunker wall, so that higher forces can be absorbed and dissipated via the mounting.
  • the positive connection between the support arm and the locking element is designed so that the forces acting on the support arm can be reliably absorbed, it does not matter which parts of the locking element interact with the support arm to produce the positive connection.
  • the locking element it is possible for the locking element to at least partially encompass the support arm. In a preferred version, however, the positive connection is produced over the entire lateral surface of the locking element.
  • the locking element is a bolt.
  • the support arm can comprise one or more support legs connected to one another. Adjusting nuts and/or adjusting screws can be provided for alignment.
  • the bunker wall can also be moved manually, but in order to further increase operational safety when using a bunker, it is suggested that a lifting arm for moving the bunker wall is provided for the bunker wall.
  • a lifting arm for moving the bunker wall is provided for the bunker wall.
  • the support arm does not necessarily have to fulfill this lifting function, but a separate lifting arm can also be provided in addition to the support arm. This has the advantage that the lifting and supporting functions can be clearly divided between both arms and neither arm has to be modified in such a way that its actual function is impaired.
  • the lifting arm can be moved using a linear drive, for example. In a preferred embodiment, the lifting arm is driven hydraulically.
  • the locking element has a signal section which, when the support arm is in the fixed state, protrudes from the area of the positive connection in the fixing direction.
  • the signal section is used to visually check the form fit, as it only protrudes from the area of the form fit if the form fit has been properly established.
  • This type of checking has the advantage that no error-prone systems, such as electronic warning systems, have to be installed and the checking can still be carried out easily from a safe distance.
  • the locking element on the signal section can have a marking that can be easily identified visually.
  • the positive connection is made via a bolt as a locking element in an opening in the support arm
  • a section of the bolt can be colored, with the user determining the correct positive connection when the colored area protrudes from the opening and its position can thus be clearly perceived visually.
  • a particularly space-saving embodiment in which the form fit according to the invention can be produced in a variety of ways, results when the support arm comprises two support legs connected to one another via a joint and the locking element in the operating position in the area of the joint on the support arm attacks. Due to the two support legs, the support arm can be stored compactly, especially in the transport position.
  • the positive connection for fixing the support arm in the operating position can be achieved by mechanically blocking the pivoting movement of a support leg in the area of the joint, for example by providing a breakthrough in the area of the joint, or by blocking a support leg in the area of the joint.
  • a stiffening and/or widening of the support leg can be provided in the area of the joint, which increases the stability of the support arm or the strength of the positive connection.
  • the locking element engages the shorter leg due to the acting moments.
  • the legs are pivotally connected to the bunker wall or to the base on the side facing away from the joint, with two or more pivot axes of the connections of the legs to the bunker wall and/or the base and/or the joint running parallel to one another.
  • the inventive engagement of the locking element in the operating position in the area of the joint on the support arm also results in an advantageous introduction of the forces and thereby low shear forces in the locking element.
  • one support leg is adjustable in length.
  • the length of the support leg is adjustable, which is easier for a user to access in an ergonomic position, as the ease of use can be increased in this way.
  • the operational safety can be further increased if a remotely operable drive is provided, which is drive-connected to the locking element for positively locking the support arm in the operating position.
  • a remotely operable drive is provided, which is drive-connected to the locking element for positively locking the support arm in the operating position. This eliminates the need for direct manual manipulation by the user and the locking element can be moved while maintaining a safety distance. Since, as already mentioned, the force required for positive locking does not have to be applied against the weight vector, a relatively low-power linear motor can be used, for example be used as a drive. Since the locking device according to the invention is usually used for material processing machines such as crushers or mobile screening systems, an actuating cylinder can also be used as a drive with hydraulics already present in these cases.
  • the locking element and its remote-controlled drive can be combined into a compact locking unit that can be installed in the immediate vicinity of the support arm, for example on the base or on the bunker wall.
  • a locking device comprises a support arm 1 which supports a bunker wall 2 on a base 3.
  • Bunker wall 2 and base 3 are part of a bunker that can be used for material processing machines, such as crushers or screening plants.
  • the bunker wall 2 is movably mounted on the base 3, so that it is possible to switch between a compact transport position and a more expansive operating position. In the operating position, material to be processed, for example bulk material, impacts the bunker wall 2, which means that it is exposed to high forces and therefore high loads.
  • the support arm 1, which supports the bunker wall 2 in the operating position is fixed via a positive fit that is formed between the support arm 1 and a locking element 4, so that the bunker wall 2 is not knocked out of the operating position due to the forces acting.
  • Locking element 4 can be moved along a fixing direction, whereby the positive connection can be both established and released.
  • the support arm 1 be fixed in the operating position via the positive connection between the support arm 1 and the locking element 4, but the forces acting on the support arm 1 can also be introduced into the base 3 via the locking element 4.
  • the locking element 4 as shown in the present exemplary embodiment, is mounted on the base 3, since this creates a direct transmission of force between the support arm 1 and the base 3 and relatively high forces can be absorbed and dissipated.
  • the support arm 1 can also have a lifting function for moving the bunker wall 2, in order to avoid that such a support arm 1 has to be modified to produce the positive connection, it is recommended, as in the embodiment shown, that next to the support arm 1 Lifting arm 5 is provided so that the functions of shifting and supporting can each be carried out by a specially designed arm.
  • the positive connection can be produced in a particularly simple construction if the support arm 1 has an opening 6 into which the locking element 4 can be inserted in a fixing direction for positively locking the support arm 1 in the operating position.
  • the positive connection can be produced over a large part or the entire lateral surface of the locking element 4 without having to modify the support arm 1 in a complex manner.
  • the locking element 4 is a bolt that engages in the opening 6, since a bolt can simply be displaced linearly to produce the positive connection. The forces acting can cause deformations, especially during prolonged operation.
  • the support arm 1 is adjustable in length, whereby the opening 6 arranged on the support arm 1 can be aligned transversely to the fixing direction. Since the support arm 1 is arranged pivotably, the opening 6 can be aligned on a plane transverse to the direction of displacement of the locking element 4.
  • the support arm 1 can be pivoted along a pivot axis. This allows the support arm 1 to be arranged compactly in both positions. In order to arrange the locking element 4 in an equally compact manner, the locking element 4 can be displaced parallel to the pivot axis. Forces acting on the support arm 1 are most likely to cause an unwanted pivoting about the pivot axis, which can be efficiently prevented by the positive fit.
  • the support arm 1 can be made particularly compact if it comprises two support legs 8, 9 connected to one another via a joint 7 and the locking element 4 engages the support arm 1 in the operating position in the area of the joint 7. In addition to this compact design, the moments in the area of the joint 7 can be better absorbed, especially if the area around the joint 7 is stiffened to produce the positive connection.
  • the user can even check the positive connection while maintaining a safety distance if the locking element 4 has a signal section 10.
  • the signal section 10 differs in design from the rest of the locking element 4, so that the user can easily visually perceive the difference to the rest of the locking element 4 and preferably also to the other components of the locking device. This can be achieved, for example, by using different colors.
  • the user In order to be able to verify the form fit visually, the user must recognize that the locking element 4 protrudes from the form fit. This can be easily accomplished by using the signal section 10. Although such a verification is in principle also possible without the signal section 10, the distance from which this verification is clearly possible can be increased by the signal section 10 and a safety distance can thereby be maintained.
  • a remotely operable drive 11 can be provided for the locking element 4, since this can prevent a user from having to manipulate the locking element 4 in the immediate vicinity and/or manually to produce or release the positive connection. Due to the remote operability of the drive 11, the positive connection, and thus the fixing of the support arm 1, can take place at a safe distance and the risk of injury to the user is reduced.
