Definitions

  • the invention relates to a block lock for round steel chains for mining with the features of the preamble of claim 1.
  • chain locks are used to transmit high tensile forces, for example in planing systems, in order to lengthen chains or to repair broken chains.
  • the chain locks must be divisible in half in order to attach them to existing chain links at one end of the chain.
  • the requirement for the chain lock is not only to be able to reliably transmit the high tensile forces within the chain strand, but also to offer sufficient strength in the event that the chain lock is not along the longitudinal axis due to an inclined position, for example on a deflection roller is loaded, but diagonally or even across it.
  • the geometry must be such that the adjoining chain elements can be securely picked up, but also remain flexible.
  • the chain lock should run within the chain strand and should also be able to be guided over deflection devices or other guide devices without getting caught.
  • the chain locks for use in mining are between
  • Flat locks according to DIN 22258-1 and block locks according to DIN 22258-2 distinguished.
  • the flat lock is used in the planing chain, whereas the block lock is mainly used for conveyor chains
  • the flat lock can run both horizontally and vertically through the sprocket.
  • the block lock may only run vertically through the chain wheel.
  • a block lock of the generic type is known from DE 203 07 184 U1, which is designed in such a way that the height measured transversely to the longitudinal extension of the chain strand is not greater than that of the adjacent chain links. Because two retaining grooves and two retaining webs are provided for connecting the half-elements, reliable power transmission is also achieved when the block lock runs, for example, around a deflection wheel, with forces occurring at an angle to the longitudinal axis which occur due to the overlapping flanks on the guide grooves and Leaders can be transferred.
  • the disadvantage of the known block lock is that it can only be installed by means of an assembly direction oriented transversely to the longitudinal extent of the chain strand.
  • the two chain ends must first be held freely in front of each other.
  • a half element of the block lock is inserted into each of the chain ends.
  • the half-elements are then shifted against each other in such a way that the retaining webs can be inserted into the associated retaining grooves.
  • the block lock After the half-elements have been assembled to form the chain lock and are secured against each other by a locking pin, the block lock must still be swiveled 90 ° from its installation position in its position of use so that it fits into the longitudinal extension of the chain strand.
  • the object of the present invention is to improve a block lock of the type mentioned at the outset in such a way that it can be installed in the horizontal chain strand and that, in addition, two eyes separated from one another by a central web are formed in the finished block lock, in each of which a chain link to be led.
  • block locks designed according to the invention can also be used for other fields of application where there are similar dimensions, for example anchor chains.
  • a multi-stage toothing is provided in the half-elements of the block lock according to the invention.
  • This is formed by two parallel retaining webs and retaining grooves, which are located in the middle of the finished block lock, at the level of the receptacles for the chain links, are arranged.
  • the flanks of the retaining grooves and retaining webs remain largely unloaded as long as the chain is guided in a linear manner, and only a temporary loading of the flanks occurs at deflection points or in the event of chain misalignments that occur for other reasons.
  • An essential feature of the block lock according to the invention lies in the fact that the retaining webs and retaining grooves are each of different lengths and are arranged on receiving areas which are formed by insertion pins and receiving pockets.
  • the insertion pin with the outwardly projecting retaining webs has the longer side at the parting plane and tapers towards the outer edge of the block lock, towards the longitudinal web, whereas the receiving pockets, in the side flanks of which are formed the holding grooves, have the narrow side in the parting plane and from there extend outwards, towards the longitudinal web.
  • the receiving areas are preferably trapezoidal in cross-section or viewed from the side.
  • the boundary edges are straight, which is easier to edit and coordinate with one another than with the curved shapes that are also conceivable in principle.
  • This configuration of the connection areas of the half-elements results in an assembly direction that is not exactly perpendicular to the longitudinal axis, but is inclined at an angle of about 60 ° to 85 °.
  • the assembly can be done in two ways.
  • the half-elements, including the chain links at the ends, can be put together in the above-mentioned, inclined assembly direction until they lie against one another before finally an axial thrust in the longitudinal direction takes place, with which the positive locking between the half-elements is produced.
  • the second variant of the assembly which enables the block lock according to the invention, has the advantage that a provisional form-fit is already achieved in an intermediate layer, so that the half-elements already have a transverse and a longitudinal leg after the first sequence - motion can no longer fall apart:
  • the stair-shaped assembly enables z. B. assembly in the horizontal chain strand without the chain ends having to be held up.
  • the lower panel element can be placed on the surface for assembly.
  • the chain links at the end of the chain sections to be connected to one another are each inserted into one of the pile elements, it preferably being provided that an inner flank on the pile element runs out in a hook shape in the direction of the parting plane, so that the chain link there is form-fitting is held.
  • the longer FH footbridge When assembling the flalel elements, the longer FH footbridge must first be pushed freely into the pocket. Then it can be pushed into the short flute groove in the longitudinal direction by a slight feed movement.
  • the pile elements are then pressed together again transversely to the longitudinal direction, so that the long fold web, which is closer to the parting plane, is brought out of the short groove to the fleas of the adjacent long groove.
  • the direction of assembly is therefore not necessarily linear, but it can also be stepped, the two chain links in the latter variant already being held securely in the intermediate step and the two Half elements are positively coupled with each other to the extent that they can no longer be accidentally torn apart.
  • the central web which is preferably present despite the short assembly path, prevents the halves from deflecting inwards under load, which in turn relieves the teeth of additional stresses caused by deflections.
  • the central web of the block lock is preferably formed by two individual central webs, each of which extends inwards from the longitudinal webs of the half-elements, that is to say in the direction of the eyes to be formed. The end faces of the central webs lie in front of each other in the parting plane.
  • the central web can extend as far as the central axis of the block lock, so that a gapless web is present after the assembly.
  • the central web can also be designed to be somewhat less high, so that the central webs, which point towards one another with gaps, nevertheless ensure the separation of the two chain links. To do this, the gap only has to be smaller than the diameter of the chain links to be connected.
  • FIG. 1 shows a block lock according to the invention in a perspective view before assembly
  • FIG. 2 shows a half element for a block lock in a perspective view
  • FIG. 1 shows a block lock 100, which is formed from two half-elements 10, in a perspective exploded view.
  • the half-elements 10 are preferably of identical design.
  • the arrow between the half elements 10 indicates the mounting direction M, in which the upper half element 10 is placed on the lower half element 10, and the dash-dotted line the position of a longitudinal axis L.
  • Each half element 10 has a longitudinal web 10.1, at one end of which an insertion pin 11 is formed, the width of which is significantly reduced compared to the other sections.
  • the insertion pin 11 is delimited by a flank 11.2 which extends obliquely upwards, with an inclination towards the center.
  • the front edge 11.1 of the insertion pin 11, on the other hand, extends obliquely outwards from the outside to a parting plane that runs through the longitudinal axis L, so that a trapezoidal shape of the insertion pin 1 results in the side view.
  • a receiving pocket 12 is formed, which is also delimited by an oblique flank 12.2, the inclination of which corresponds to the inclination of the flank 11.2 on the insertion pin 11.
  • Receiving pockets 12 and insertion pins 11 form mutually complementary receiving areas; this means that recesses and grooves on one side interact with projections and webs on the respective counterpart.
  • a central web 10.2 is formed between the insertion pin 11 and the receiving pocket 12 and projects transversely from the longitudinal web 10.1.
  • bores 17, 18 are provided, into which securing pins 20 can be inserted later, after the half-elements 10 have been joined.
