Abstract
The utility model discloses a chain hinge pin which comprises a cylindrical hinge pin body. One top end of the hinge pin body is provided with a stop table, wherein the stop table and the hinge pin body are of an integrated structure. The other end of the hinge pin body is provided with an outer thread which is connected with a nut in a threaded mode, wherein through holes which are mutually communicated are formed in the other end, provided with the outer thread, of the hinge pin body and the nut. A dowel is movably arranged in the through holes. The chain hinge pin has the advantages that the thread is machined at the end of the hinge pin, the nut is used for locking a chain plate of a chain, the fastening effect is good, the hinge pin is not prone to outward disengagement, and in addition, detaching and maintaining are convenient; the combination manner of the nut and the dowel is adopted, and therefore the axial fixing strength on the chain plate by the hinge pin is further improved; the hinge pin is simple in structure, short in machining and manufacturing period, capable of being used repeatedly, low in cost, good in using effect and capable of greatly prolonging the overall service life of the chain of a conveying device.
Description
Technical field:
The utility model relates to the chain hinge pin that a kind of stacker-reclaimer upper scraping plate chain uses.
Background technique:
In stacker-reclaimer running,, easily there is connecting link pin and cut off by the carrier bar of chain in the connecting link pin unreasonable structure of flight chain during vibration, bearing pin easily exits between carrier bar, causes whole chain breakage, breaks down, and has a strong impact on normal production.
Model utility content:
The purpose of this utility model is to provide a kind of axial restraint intensity of bearing pin to carrier bar, fastening effective chain hinge pin of improving.
The utility model is implemented by following technological scheme: a kind of chain hinge pin, it comprises cylindrical bearing pin main body, on described bearing pin main body one top, be provided with gear platform, described gear platform and described bearing pin main body are into a single integrated structure, at the described bearing pin main body the other end, be provided with outside thread, and be bolted with nut, and be provided with the through hole being interconnected being provided with on the externally threaded described bearing pin main body the other end and described nut, at described through hole, be movably equipped with pin.
Advantage of the present utility model: end part of pin shaft machining screw, with the carrier bar of nut check chain, fastening effective, bearing pin is difficult for outwards exiting, and detachable maintaining is convenient; Use nut to add the compound mode of pin, further improved the axial restraint intensity of bearing pin to carrier bar; Pin shaft structure is simple, and the processing and fabricating cycle is short, reusable, and cost is low; Using effect is good, and the whole service life of conveying equipment chain is increased greatly.
Accompanying drawing explanation:
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is use schematic diagram of the present utility model.
Fig. 3 is the plan view of Fig. 2.
Bearing pin main body 1, gear platform 2, nut 3, through hole 4, pin 5, interior 6, outer plate 7, roller 8.
Embodiment: as shown in Figure 1, a kind of chain hinge pin, it comprises cylindrical bearing pin main body 1, on bearing pin main body 1 one tops, be provided with gear platform 2, gear platform 2 is into a single integrated structure with bearing pin main body 1, is provided with outside thread, and is bolted with nut 3 at bearing pin main body 2 the other ends, be provided with the through hole 4 being interconnected being provided with on externally threaded bearing pin main body 1 the other end and nut 3, at through hole 4, be movably equipped with pin 5.
Operation instruction: as shown in Figures 2 and 3, the carrier bar of chain comprises interior 6 and outer plate 7, be connected successively by bearing pin main body 1 with outer plate 7 for interior 6, in every internally bearing pin main body 1 between sheet 6, cover has roller 8, the gear platform 2 of bearing pin main body 1 one end and the outside of a side outer plate 7 fit tightly, bearing pin main body 1 the other end is spirally connected and the nut 3 that screws fits tightly with the outside of opposite side outer plate 7, bearing pin main body 1 end machining screw, with nut 3 locking carrier bars, fastening effective, bearing pin main body 1 is difficult for outwards exiting, and detachable maintaining is convenient, bearing pin main body 1 is reusable, cost-saving, pin 5 is plugged in bearing pin main body 1 and the coconnected through hole 4 of nut 3, and use nut 3 adds the compound mode of pin 5, has further improved the axial restraint intensity of 1 pair of chain of bearing pin main body.
