Wipe, it is to avoid the scraper conveyor chain broken prevention device that bearing pin fracture accident occurs.
Above-mentioned purpose is realized by techniques below scheme: develop a kind of scraper conveyor chain broken prevention device, including two
Scraper plate between bar chain and chain, chain includes carrier bar and bearing pin, and carrier bar includes inner plate, outer plate and the company of scraper plate outer end
Plate, carrier bar is connected with bearing pin by axis hole, and bearing pin one end is provided with the diameter axle cap more than axis hole, and the other end is provided with diameter more than axle
Hole anticreep snap ring, is characterized in: the pin-and-hole outer end of described outer plate and connecting plate is respectively equipped with groove, and diameter and the degree of depth of groove are equal
More than bearing pin axle cap and anticreep snap ring, after bearing pin is installed with carrier bar, axle cap and the anticreep snap ring of bearing pin are in groove, bearing pin
Two ends i.e. axle cap and the outer face of anticreep snap ring less than the plate face of carrier bar.
The end of described carrier bar is inclined-plane, and wherein, the inclined-plane of outer plate end is to tilt inside scraper chain, inner plate
Inclined-plane is to tilt to the outside of scraper chain, and the inclined-plane of connecting plate is the end of connecting plate bending side inside scraper chain.
The beneficial effects of the utility model are: axle cap and the anticreep snap ring of bearing pin are assembled in groove, are greatly decreased and slip
Groove and the impact of material and abrasion, the fault of bearing pin significantly reduces, and the service behaviour of scraper plate transveyer is more stable, and productivity ratio is big
Width improves, and has simple in construction, the advantage such as cheap, safe and reliable, and application prospect is the most considerable.

Detailed description of the invention
The first embodiment: Fig. 1 describes the drag conveyor of a kind of double-strand, and both sides are respectively arranged with a scraper chain 1, and middle part is pacified
Fill a plurality of scraper plate 6.Scraper chain 1 is made up of carrier bar 2 and bearing pin 3, and carrier bar 2 therein includes inner plate 4, outer plate 5 and connecting plate
7.Visible in conjunction with Fig. 2: carrier bar 2 is one piece of rectangular slab, and two ends have axis hole 8.Visible in conjunction with Fig. 3: connecting plate 7 is fixed on scraper plate 6 liang
End, is the rectangular slab relative with carrier bar, and two ends have axis hole 8.Visible in conjunction with Fig. 4: bearing pin 3 is a strut piece, its external diameter and axle
Match in hole 8.One end of bearing pin 3 has diameter to be more than the axle cap 10 of pin diameter, and the other end of bearing pin 8 is provided with a diameter and is more than
The anticreep snap ring 11 of pin diameter, the diameter of anticreep snap ring 11 and thickness are consistent with axle cap 10 is advisable.The length of bearing pin 3 has two
Kind, only the bearing pin 3 of the company's of wearing inner plate 4 and outer plate 5 is comparatively short, needs the company's of wearing inner plate 4, outer plate 5 and the bearing pin 3 of connecting plate 7
Long.By Fig. 2, Fig. 3 it can be seen that this example improvements introduced is: axis hole 8 outer end of outer plate 4 and connecting plate 7 is provided with groove
9, the diameter of groove 9 is more than bearing pin axle cap 10 or the external diameter of anticreep snap ring 11, and the degree of depth of groove 9 is not less than axle cap 10 and anticreep
The thickness of snap ring 11.As it is shown in figure 5, after bearing pin 3 and carrier bar 2 connect, axle cap 10 and the anticreep snap ring 11 of pin 3 axle are in groove
In 9, the two ends of the bearing pin 8 i.e. outer face of axle cap 10 and anticreep snap ring 11 is less than the plate face of carrier bar 2.
Due to bearing pin 3 two all with carrier bar 2 flush or inside contract, in running, with material and adjacent object phase
Impact the least, both decreased resistance, again Wear, significantly extend service life.According to laboratory observation, the pin prominent with two ends
Axle is compared, and the service life of this bearing pin can extend more than 2 times, and the abrasion of bearing pin mostly is findable fair wear and tear, and it is changed
Also for naturally changing, unexpected fracture accident do not occur, the fault rate of scraper chain declines to a great extent.
The second embodiment: on the basis of the first embodiment, is improved the end shape of carrier bar 2.Originally
Carrier bar 2 front end be the end face vertical with direction of advance, although this end face is little, but in the middle of running, and material with
And between neighbouring device, also can produce bigger impact, it is to cause the main cause that bearing pin damages and carrier bar damages.After improvement
The end of carrier bar 2 be inclined-plane 12.As shown in Figure 6, the inclined-plane 12 of outer plate 5 end is to tilt to the inner side of scraper chain 1.Such as figure
Shown in 7, the inclined-plane of inner plate 4 is to tilt to the outside of scraper chain 1.As shown in Figure 8, the inclined-plane 12 of connecting plate 7 is the end of connecting plate 7
Bending side 13 inside scraper chain 1.After installation as it is shown in figure 9, before and after outer plate 5, inner plate 4 and connecting plate 7 two ends be
Inclined-plane 12, the outer end of the outer plate 5 that the bending side at connecting plate 7 two ends 13 connects together be wrapped in the inside, define one bigger
Inclined-plane 12.During advance, the impact with material and other barriers can significantly diminish, and the service life of carrier bar and bearing pin is at double
Prolongation.
