Abstract
The utility model discloses a tool for testing the tensile load of a single link plate. The tool comprises two pull rods and two tension pin shafts, wherein a clamping groove and a through hole are formed at the front end of each pull rod, the direction of the clamping groove is the same as the axial direction of the pull rod, the through hole is perpendicular to and intersected with the clamping groove, and the intersection is positioned in the clamping groove; and the tension pin shafts of which the diameter is smaller than that of an upper hole of a to-be-tested link plate can be inserted into the through holes. The tool provided by the utility model has a simple structure, is convenient to operate, and enables the test of the chain link plate to be convenient and fast.
Description
Technical field
The utility model relates to a kind of easy instrument that is applied to the detection of chain and chain-plate tensile load, and whether the tensile load that detects chain and chain-plate reaches technical requirement.
Background technology
The tensile load of chain and chain-plate is the important technology index in production and the use; The tensile load of the carrier bar of chain is directly connected to the tensile load of chain chaining; The tensile load of chaining is the important performance index of chain; The tensile load of carrier bar then is its basic comprising, need detect the testing tool that does not also have at present.
The utility model content
The technical matters that the utility model will solve is that existing chain and chain-plate tensile load detection method wastes time and energy, degree of accuracy is low, and a kind of easy instrument that the chain and chain-plate tensile load detects that is applied to is provided.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of testing tool of monolithic carrier bar tensile load; Comprise two pull bars and two pulling force bearing pins, said pull bar front end is equipped with draw-in groove and through hole, and said draw-in groove direction and pull rod shaft are to consistent; Said through hole and draw-in groove intersect vertically, and the intersection is positioned at draw-in groove; Said pulling force bearing pin can insert in the through hole, and its diameter is less than the diameter in hole on the carrier bar to be measured.
The utility model has the advantages that: testing tool is simple in structure, easy to operate, makes that the testing of chain and chain-plate is convenient and swift.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the structural representation of existing carrier bar.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
Shown in Fig. 1-2, the utility model comprises two pull bars 1 and two pulling force bearing pins 4, and said pull bar front end is equipped with draw-in groove 2 and through hole 3, and said draw-in groove 2 directions are axially consistent with pull bar 1, and said through hole 3 intersects vertically with draw-in groove 2, and the intersection is positioned at draw-in groove 2; Said pulling force bearing pin 4 can insert in the through hole 3, and its diameter is less than the diameter in hole 5 on the carrier bar to be measured.
During use, carrier bar two ends to be detected are snapped in respectively in the draw-in groove 2 that does not insert pulling force bearing pin 4, and make the position at 5 aligned through holes, 3 places, hole on the carrier bar; Then, insert pulling force bearing pin 4, and make it to run through the hole 5 on through hole 3 and the carrier bar; Through pulling force bearing pin 4 carrier bar is fixed in the draw-in groove 2, last, this testing tool is installed on hydraulic pressure puller system or the electronic tensile machine; Slowly apply and carry load, when carrier bar was broken, puller system dial plate institute data presented was the tensile load of carrier bar.
