Description
Technical Field
The utility model relates to a round pin axle technical field especially relates to a round pin axle of cold quick-witted four-bar linkage of comb.
Background
A new generation of domestic and foreign grate cooler with a four-bar mechanism has compact design, but has the defects of inconvenient four-bar replacement and shutdown replacement: because the length of the four-connecting-rod pin shaft is 80mm and the clearance between the four-connecting-rod and the brackets at two sides is only 70mm, the four-connecting-rod can not be drawn out due to insufficient clearance when the four-connecting-rod is replaced under the grate of the grate cooler, and the four-connecting-rod can only be taken out and installed from the grate after the machine is stopped and the production is stopped for at least 50 hours to clean clinker from the grate and remove other components. For example, the four-bar linkage of the cn201320498360.x utility model is as follows: the pin shaft comprises a pin shaft end cover and a pin shaft rod 2, and is integrated, the thickness of the pin shaft end cover is 12mm, the pin shaft rod part is 68mm, and the total length of the pin shaft is 80 mm.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the above problem, providing a cold quick-witted four connecting rods's of comb round pin axle, round pin axle detachable is split type, receives the restriction in space to reduce when using, and change four connecting rods that can be more nimble need not all to stop production, has reduced maintenance duration.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a pin shaft of a four-connecting-rod of a grate cooler comprises: the hinge pin comprises a hinge pin end cover and a hinge pin rod, wherein a first connecting hole is formed in the hinge pin end cover, a second connecting hole is formed in the hinge pin rod, and the hinge pin end cover and the hinge pin rod penetrate through the first connecting hole and the second connecting hole through a connecting piece to be connected.
The edge of the first connecting hole is provided with threads.
And the edge of the second connecting hole is provided with threads.
The connecting piece is an M12X 30 bolt, an M12X 35 bolt, an M12X 40 bolt.
The circle center of the first connecting hole is located on the central line of the pin shaft end cover.
The circle center of the second connecting hole is located on the central line of the pin shaft rod.
The utility model has the advantages that:
the clinker on the grate is not required to be cleaned and other parts on the four-connecting rod are not required to be dismounted, the grate bed where the four-connecting rod to be replaced is only required to be shielded, the yield is reduced by about 25%, the four-connecting rod is not required to be dismounted even if the grate bed and other parts on the four-connecting rod are overhauled and replaced in the shutdown process, the connecting bolt, the pin shaft end cover and the pin shaft rod are sequentially taken down under the grate, and the four-connecting rod can be replaced after the pin shaft of the four-connecting rod is taken down for 8-10 hours, so that the working efficiency is improved. When in installation, the pin shaft rod is firstly installed, and the pin shaft end cover is fastened together by the connecting bolt 1 and the pin shaft rod.
