Abstract
A link has two link parts (1, 2), wherein the link parts can mutually move for a limited distance to open and close the link; a stop pin (5) for ensuring the link parts (1, 2) mutually connected with each other by lugs (10) which fit into recesses (12) at either end, coupled with each other at the locking position. The stop pin (5) is installed in aligned holes (3, 4) in area of terminal of the link parts (1, 2) and the holes are sited on the plane vertically extending across the link parts (1, 2).
Description
Technical field
The present invention relates to a kind of chain link (Kettenschloss) that is used for link chain, this chain link in form is locked in locking chain link on the locked position for a kind of by at least one stop pin, described locking chain link is at vertical position process sprocket wheel and comprise two chain link parts, described chain link part can move limited distance mutually so that opening and locking chain link, and have a vertical limit respectively, a containing seat that is used for tenon is set being provided with on a tenon and another end on the end on this vertical limit on this vertical limit.
Background technique
The chain link of known above-mentioned form from DE 23 54 028.In this known chain link, use a stop pin that is driven in the hole, the sidewall of described hole extend past tenon and tenon containing seat in the zone of one of chain link end.In order in this chain link, stop pin to be installed, the chain link that hangs on the chain link end that is provided with the hole that is used for stop pin must be converted to an oblique position from its normal position, so that the hole opening is open, in described normal position, the longitudinal axis of chain link and the axis alignment of chain link.Bearing of essential in addition consideration, when squeezing into stop pin, chain link can be with respect to described bearing support.Described two kinds of situations make known chain link assembling and the dismounting all the difficulty.
By following measure assembling is obviously simplified, promptly stop pin is offset in the hole, this hole is arranged in the plane that extend past is locked vertical limit, as this in the chain link of disclosed form among DE 28 13 748 C2 by the practical application, in this chain link, aperture is crossed vertical limit and center fishplate bar that two chain link parts of chain link are bonded together of lock.In this case, be driven into when with stop pin in the hole of its setting the time, hanging over chain link on the chain link does not need normal position deflection from it, and chain link can be bearing on the base plate that chain conveyor exists usually.Yet this situation proves disadvantageous in known chain link, and the hole that is used for stop pin is positioned at the zone of chain link, has critical stress ratio and duty factor in this zone.Therefore on the chain ring surface of base plate, often forming so-called friction martensite (Reibmartensit), this friction martensite impels generation to lie across the temperature jump danger of throughput direction expansion, and it can cause the fracture at the zone in the hole that is used for stop pin chain link.
Summary of the invention
The objective of the invention is to, in a kind of chain link of above-mentioned form, the stop pin that will be used for chain link is installed in a position of chain link, and this position all is that proof is favourable for the operability of chain link in assembling and dismounting but also for the intensity of chain link not only.Above-mentioned purpose reaches by following measure by the present invention, be that stop pin is arranged in the hole of mutual aligning in the zone of chain link part end, these holes are arranged in the plane of the longitudinal axis on a vertical limit of extend past chain link part, and one of stop pin cross-over connection is at the end face of the tenon that is provided with one of them hole with hold seam between the bottom of containing seat of tenon.
By the chain link that is used for link chain of the present invention, this chain link in form is locked in locking chain link on the locked position for a kind of by at least one stop pin, this locking chain link passes through sprocket wheel and comprises two chain link parts on vertical position, described chain link part can move limited distance mutually so that chain link is opened and locking, and has a vertical limit respectively, a containing seat that is used for tenon is set being provided with on a tenon and another end on the end on this vertical limit on this vertical limit, it is characterized in that, stop pin is arranged in the hole of mutual aligning in the end regions of described chain link part, these holes are arranged in the plane that a longitudinal axis by the vertical limit of described chain link part extends, and one of stop pin cross-over connection is at the end face of the tenon that is provided with one of them hole with hold seam between the bottom of containing seat of tenon.
By stop pin being moved to the chain plane of a loop that has a material cross-section obviously higher with respect to the vertical limit of chain link in the locking chain link, the quiet lotus intensity that not only can improve chain link also can improve the live load intensity of chain link.
For the assembling that makes chain link and dismounting all make things convenient for, the length in the hole that is used for stop pin by the tenon extension equals the length of stop pin at least, and this hole provides the space for stop pin outside the zone of the seam for the treatment of cross-over connection.
Description of drawings
Below illustrate in greater detail the present invention by means of embodiment illustrated in the accompanying drawings.In the accompanying drawing:
The side view of the chain link of locking on its locked position that Fig. 1 illustrates with partial cross section,
Fig. 2 presses the plan view of the chain link of Fig. 1, and
Fig. 3 for dismantle and open insurance chain link with the corresponding side view of Fig. 1.
Embodiment
1 and 2 is two chain link parts of a locking chain link in Fig. 1 and 3, is known in the reference that their basic structure is mentioned from the outset and does not need more detailed description.The end on part 1 right side has a hole 3 in view, and the right-hand end of part 2 is provided with a hole 4.The through holes of an integral body are aimed at and are formed in two holes 3 and 4 mutually under the state that chain link part 1,2 is slippaged together.The end that hole 3,4 deviates from mutually is broadened, and is provided with one and makes stop pin 5 be easy to be inserted into insertion slope 6 in the hole 3.
Because the structural type of sprocket wheel, each locking chain link is process sprocket wheel on the vertical position only.As directed situation is if they, show like this that it is essential settling the position assembling indication 7 of a definite chain lock in the chain thigh only by 5 lockings of a stop pin.
In Fig. 1, stop pin 5 is connected across the end face 9 of chain link part 2 tenons 10 and is arranged on seam 8 between the bottom 11 of the containing seat that is used for tenon 10 12 in the chain link part 1. Chain link part 1 and 2 position are reciprocally locked thus.
In order to take chain link apart, stop pin 5 is removed from seam 8 zones, make chain link part 1 can be passed to the right, so that the tenon 10 of chain link part 1,2 ends is removed from their containing seat 12 according to the direction of arrow among Fig. 3 13.
Because length 1 maximum of stop pin 5 equals to pass the length L in the hole 4 of tenon 10, the latter provides enough spaces for shift out stop pin 5 from locked position.Therefore do not need to shift out when the insurance of opening chain link perpendicular to the chain link of a unshowned base plate from its position.
