Problems solved by technology

Since the chain elements connected to each other via the known segmented locks are not separated by an intermediate rib, there is a risk of galling, ie two chain elements can be arranged side by side on one side of the eyelet, whereby there is no tension in the longitudinal direction of the chain. Pull segment locks, but may be arranged horizontally

Embodiment Construction

[0027] figure 1 An exploded perspective view of a segmented lock 100 is shown, which is formed from two half elements 10 . The half elements 10 are preferably of identical design. The arrows between the half-elements 10 indicate the installation direction M in which the upper half-element 10 is slipped onto the lower half-element 10 , and the dotted line shows the position of the longitudinal axis L. FIG.

[0028] Each half-element 10 has a longitudinal rib 10.1, at one end of which a push-in pin 11 is formed, wherein the width of the push-in pin is significantly reduced compared to the other sections. Formed on the outer side of the push-in pin 11 are two holding ribs 13.1, 13.2 of different lengths. The push-in pin 11 is delimited by a side surface 11.2, which extends obliquely upwards, to be precise towards the middle. In contrast, the end-side edges 11 . 1 of the push-in pin 11 each run obliquely outwards from the outside toward a separating plane extending through the ...

Abstract

A block lock (100) for round steel chains, having two half-elements (10) which are displaceable relative to one another for opening and closing the block lock (100) and which each have ends connectedto one another via a longitudinal web (10.1), of which in each case one end has an insertion plug (11) with a width reduced in relation to the longitudinal web and with retaining webs (13.1, 13.2) integrally formed on both sides, wherein at least two parallel retaining webs (13.1, 13.2) are arranged above one another on each side, and of which in each case the other end has a receiving pocket (12)which serves to receive the insertion plug (11) and on the two lateral inner flanks of which there are in each case formed at least two retaining grooves (14.1, 14.2) above one another to form a toothing by receiving the retaining webs (13.1, 13.2). A central web (10.2) extends inwardly from at least one longitudinal web (10.1). The insertion plug (11) widens, as seen in side view, from the longitudinal web (10.1) towards its end, and the length of the retaining webs (13.1, 13.2) increases. At the same time, the receiving pocket (12), as seen in side view, narrows from the longitudinal web (10.1) to its end.

Description

technical field [0001] The invention relates to a section lock for round steel chains for mining having the features of the preamble of claim 1 . Background technique [0002] In mining operations, segment locks are used in order to extend chains or to repair broken chains in order to transmit high tensile forces, for example in planing installations. Segment locks must be divisible in half to allow the segment lock to be attached to the existing chain elements at the end of the chain. It is required that the segment locks not only be able to reliably transmit high tension forces in the chain, but also that the segment locks are not loaded along the longitudinal axis, but are loaded obliquely or even transversely due to, for example, a tilted position on the deflection wheels Provide sufficient strength for the case. It is also necessary to achieve a geometry that is able to securely accommodate the connected chain elements, but also remains movable. Finally, the segment ...
