Abstract
The utility model provides a link unit is constituteed that colliery is scraper chain for shuttle car in pit is established ties by a plurality of groups in proper order each group's link unit all includes two link joints, and it has chain link I to articulate through the round pin axle between two link joints, chain link I sets up in the inboard of individual link joint, sells axle both ends in the outside of link joint and installs link joint limiting check ring respectively, keeps away from the one end of chain link I at two link joints and installs scraper blade welding piece respectively, and scraper blade welding piece is equipped with chain link II including the base between base and link joint, and II one end of chain link are fixed with the base and are met, and II other ends of chain link pass through the articulated shaft and hinge with the link joint, be fixed with the unload coal scraper blade of usefulness of shuttle car on the base. The utility model discloses being difficult for fracture, non -deformable, not fragile, having improved the tensile strength of chain greatly, the tensile load can reach 1000KN, the difficult fracture of link joint, and round pin axle non -deformable, chain I, II also is difficult to damage, has improved engineering tunnelling progress, has reduced engineering tunnelling cost.
Description
Technical field
The utility model relates to a kind of underground coal mine transportation equipment, particularly a kind of underground coal mine shuttle car scraper chain.
Background technology
Ore deposit underground shuttle car ore deposit is combined adopt and main transportation device in headwork process, and the principle of work of underground coal mine shuttle car is that underground coal mine shuttle car mainly contains the compositions such as running gear, steering swivel system, scraper plate transport systems, cable rolling system.In operational process, shuttle car is followed and is even being adopted machine or development machine rear portion, coal is adopted on shuttle car by Lian Caiji or development machine, by shuttle car running gear, cooperation between steering swivel system and cable rolling system is walked on crusher position and is transported to crusher on by coal from shuttle car by scraper plate transport systems, complete automatic discharging, flight chain in above-mentioned scraper plate transport systems there will be carrier bar fracture after using three to five months, bearing pin is out of shape, serious wear, catching phenomenon, due to the as easy as rolling off a log damage of chain, have a strong impact on the driving progress of engineering, add the excavation cost of engineering.
Summary of the invention
The technical problems to be solved in the utility model is for the deficiencies in the prior art, proposes one not easy fracture, not yielding, not fragile, can improve engineering driving progress, reduce the underground coal mine shuttle car scraper chain of engineering excavation cost.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of underground coal mine shuttle car scraper chain, be characterized in: the link unit of connecting successively by some groups forms, each group link unit described includes two carrier bars, between two carrier bars, have chain link by hinge
, described chain link
be arranged on the inner side of two carrier bars, be separately installed with the spacing back-up ring of carrier bar, at two carrier bars away from chain link at the bearing pin two ends, outside of carrier bar
one end be separately installed with scraper plate weldment, scraper plate weldment comprises base, between base and carrier bar, be provided with chain link
, chain link
one end and base are fixedly connected, chain link
the other end by jointed shaft and carrier bar hinged, described base is fixed with the scraper plate that shuttle car is unloaded coal.
The technical problems to be solved in the utility model can also be come to realize further by the following technical programs, and described scraper plate is arranged with 2.
The technical problems to be solved in the utility model can also be come to realize further by the following technical programs, and described thickness of link plates is 14-18mm.
The technical problems to be solved in the utility model can also be come to realize further by the following technical programs, and described pin diameter is 20-30mm.
The technical problems to be solved in the utility model can also be come to realize further by the following technical programs, described chain link
, chain link

Compared with prior art, the utility model not easy fracture, not yielding, not fragile, substantially increase the tensile strength of chain, tensile load can reach 1000KN, and carrier bar is easy fracture not, and bearing pin is not yielding, chain
,
also be not easy to damage, improve engineering driving progress, reduce engineering excavation cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
A kind of underground coal mine shuttle car scraper chain, the link unit of connecting successively by some groups forms, and each group link unit described includes two carrier bars 1, between two carrier bars 1, be hinged with chain link by bearing pin 8
2, described chain link
2 inner sides being arranged on two carrier bars 1, are separately installed with the spacing back-up ring 9 of carrier bar, at two carrier bars away from chain link at outside bearing pin 8 two ends of carrier bar
one end be separately installed with scraper plate weldment, scraper plate weldment comprises base 5, between base 5 and carrier bar, be provided with chain link
7, chain link
7 one end and base are fixedly connected, chain link
the other end is hinged by jointed shaft 3 and carrier bar, described base is fixed with the scraper plate 4 that shuttle car is unloaded coal.At the two ends of jointed shaft 3, spacing back-up ring is all installed.
Described scraper plate 4 is symmetrical is provided with 2.Described thickness of link plates is 14-18mm.Described pin diameter is 20-30mm.Described chain link
, chain link
thickness be 10-16mm.Chain link is provided with between two carrier bars
, described carrier bar and chain link
with pinned connection, bearing pin two ends are by the spacing retainer ring spacing of carrier bar, and the base of scraper plate weldment is by adapter shaft 6 and chain link
connection, adapter shaft 6 two ends are welded.Described carrier bar and chain link
,
material be 42Cr, thickness of link plates 16mm, bearing pin material 42Cr, diameter is 25mm, chain link
,
thickness 14mm, scraper plate weldment material are 42Cr.This scheme can improve the tensile strength of chain greatly, and tensile load reaches 1000KN, and carrier bar is easy fracture not, and bearing pin is not yielding, and chain is not easy to damage, and thus improves engineering driving progress, reduces engineering excavation cost.
