The present invention has stipulated in its basic conception, the chain longitudinal axis is departed from around another chain pin prolonging because of chain when causing the chain pin spacing eliminating under the form fit bonded assembly situation corresponding increases in reclining adjacent chain pin and it of an end form fit by additional fishplate bar with connecting, thereby adds the detection fishplate bar that fishplate bar is designed to detect the chain prolongation amount of appearance with estimating.Advantage of the present invention is, additionally is provided with one and detects fishplate bar and do not need extra high cost, especially need be aspect measurement technique for not taxing one's brains greatly with structure measurement chain length that may complexity.For the chain length that visualize occurs, only need to form and detect fishplate bar and at least two oil are installed to the bigger chain pin of elongation, be enough to and will detect the space that fishplate bar is arranged on the chain pin of these two adjacent installations thereby produced.Because the wearing and tearing of flat link chain rule of thumb are to appear at very equably in its length range, so a detection fishplate bar is set in a flat link chain just may be enough.
In DE-OS2811240, the additional fishplate bar of the chain lock ring of the special-purpose fishplate bar in a kind of that be designed to fix a supporting board and flat link chain of packing into has been described, it be installed on the chain pin on the one end and by its free end form fit ground around affiliated adjacent chain pin.But, do not have to propose can not unclamp with the disengaging of the additional fishplate bar end of chain pin bonded assembly and this and fixedly the appointment fixed function of fishplate bar is contradictory.
The described additional fishplate bar of DE-AS1004545 can prevent to support the link pin rotation of additional fishplate bar and the deflector roll that is placed on the link pin does not move axially, the described additional fishplate bar of DE3419981A1 can be realized one of the chain pin that is attached thereto by the function fishplate bar of the chain pin supporting side travel along the chain longitudinal axis, and the disclosed additional fishplate bar of DE-OS1803068 is designed to strengthen carrying the fixing of suspension bucket.At last, DE3347340A1 shows the wear-resisting fishplate bar of reinforcement that is hinged on the side that axially protrudes in the outer chain pin of boards, and they have realized that chain is opened and the simple change of chain length.But, all relevant therewith aforementioned additional fishplate bars do not relate to determining of chain length appear.
Stipulated according to one embodiment of present invention, detecting fishplate bar centers on affiliated chain pin and groove that a side is opened wide at it in the face of having a part on that end of support, the chain prolongation amount that the size of the relative axial overlap portion of its further groove and chain pin equals to allow, thereby when surpass allowing the chain elongation amount, groove be cancelled and detected the longitudinal axis that fishplate bar departs from out affiliated chain string being connected of chain pin.
Can stipulate, be distributed in and be provided with a plurality of detection fishplate bars on the catena of a flat link chain.
In order to detect the position that fishplate bar departs from open chain bar string trend, according to one embodiment of present invention, can be provided with one and attach troops to a unit in the detecting test station of flat link chain, for example become the detecting test station of grating or mechanical scanner form.
The one embodiment of the present of invention that will describe after drawing in the accompanying drawings.
