for achieving the above object, the utility model proposes a kind of slag conveyer chain, comprise the carrier bar group that two row are parallel to each other, every group of carrier bar group is formed by connecting by some carrier bars, between described carrier bar group, bearing pin is installed, sleeve and back-up ring, described sleeve is installed on the outside of bearing pin and bearing pin is surrounded, leave the first space between described sleeve and bearing pin, leave the 3rd space between described carrier bar and sleeve, the inner ring of described sleeve has groove, described groove is between sleeve and the 3rd space, described shield ring sleeve is located on bearing pin, and be positioned at groove, leave the second gap between described back-up ring and sleeve.

As preferably, described back-up ring is separate thrust collar, and blocking effect is good.

As preferably, the cross-sectional plane of described separate thrust collar is right-angled triangle, wherein square edge and bearing pin are fitted and are installed, another square edge is between groove walls and bearing pin, the interior end points of the hypotenuse of described right-angled triangle and carrier bar are fitted fixing, the outer end points of the hypotenuse of described right-angled triangle and the fixed installation of the inwall of groove.

As preferably, the width in described the first space is 0.1～0.3mm, stays activity space between bearing pin and sleeve, facilitates chain operation.

As preferably, the width in described the second gap is 1～1.5mm, and the width in described the 3rd space is 1～1.5mm, guarantees that bearing pin and quill shaft are to keeping certain displacement space.

As preferably, the width in described the second gap is 1.25mm, and the width in described the 3rd space is 1.25mm.

The beneficial effects of the utility model: the utility model is by adding a separate thrust collar between sleeve and bearing pin, stop the material powder to enter between sleeve and bearing pin by the gap of carrier bar, and then avoid bearing pin and sleeve hole to wear and tear, and then the service life of prolongation carrier bar, bearing pin and sleeve, thereby extend the service life of conveyer chain, can reach more than 3 years the service life of this product, and reduce maintenance, the required expense of replacing conveyer chain.

Feature of the present utility model and advantage will be elaborated by reference to the accompanying drawings by embodiment.

[specific embodiment]

consult Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, a kind of slag conveyer chain of the utility model, comprise the carrier bar group that two row are parallel to each other, every group of carrier bar group is formed by connecting by some carrier bars 1, between described carrier bar group, bearing pin 2 is installed, sleeve 3 and back-up ring 4, described sleeve 3 is installed on the outside of bearing pin 2 and bearing pin 2 is surrounded, leave the first space 5 between described sleeve 3 and bearing pin 2, leave the 3rd space 8 between described carrier bar 1 and sleeve 3, the inner ring of described sleeve 3 has groove 6, described groove 6 is between sleeve 3 and the 3rd space 8, described back-up ring 4 is set on bearing pin 2, and be positioned at groove 6, leave the second gap 7 between described back-up ring 4 and sleeve 3, described back-up ring 4 is separate thrust collar, the cross-sectional plane of described separate thrust collar is right-angled triangle, wherein square edge and bearing pin 2 are fitted and are installed, another square edge is between groove 6 walls and bearing pin 2, the interior end points of the hypotenuse of described right-angled triangle and carrier bar 1 are fitted fixing, the outer end points of the hypotenuse of described right-angled triangle and the fixed installation of the inwall of groove 6, the width in described the first space 5 is 0.2mm, the width in described the second gap 7 is 1.25mm, the width in described the 3rd space 8 is 1.25mm.
