Abstract
The invention discloses a walking beam swinging arm pin shaft fast replacement method which is characterized by including a first step of determining a moving trajectory of a swinging arm pin shaft, forming a circular hole in the position of a bearing support plate by conducting gas cutting, wherein the position of the bearing support plate corresponds to the swinging arm pin shaft when two wheel bearing supports are at the highest point, enabling the position of the swinging arm pin shaft to move to the highest points of the two wheel bearing supports when the swinging arm pin shaft needs to be replaced, fixing a moving beam through a wire cable hand-drive block so that the swinging arm pin shaft is directly opposite to the position of the circular hole in the bearing support plate, disassembling and taking out the abraded and deformed pin shaft by adopting the circular hole formed in the bearing support plate in a gas cutting mode, cleaning a shaft hole, and then well installing a new swinging arm pin shaft. The walking beam swinging arm pin shaft fast replacement method has the advantages of being capable of conveniently and quickly replacing the swinging arm pin shaft, enabling replacement operation to be completed in less than eight hours, saving a large amount of auxiliary time, saving manpower and materials, more important, not influencing production and creating more benefits.
Description
Technical field
The invention belongs to steel rolling steel coil transportation field, be specifically related to a kind of replacing options of step rate swing arm bearing pin.
Background technology
Current steel rolling mill steel coil transportation one removes the step rate equipment all adopted, because load capacity is large, move back and forth frequent, mechanical wear is serious, particularly the damage of swing arm pin is even more serious, and can take out because swing arm bearing pin running orbit does not expose space between two axletree bearings, axle swing arm bearing pin and pass bearing wear are changed very difficult, if step rate all must be hung out on request and decompose rear replacing, a large amount of handling is needed to dismantle workpiece and time, changing a swing arm pin generally needs just can complete for 5 ~ 7 days, the heavy losses that certainly will affect and produce and cause economically are changed if not the overhaul time.
Summary of the invention
For above-mentioned situation, the present invention adopts a kind of replacing options of new swing arm bearing pin, makes it complete as soon as possible when swing arm bearing pin changed by needs, saves human and material resources, the more important thing is and do not affect production, make it create larger benefit.
The object of the present invention is achieved like this,
1) first determine swing arm bearing pin running orbit, when two axletree bearing peaks, the position of swing arm bearing pin respective shaft bearing gripper shoe, circular hole is opened with gas cutting in this position of bearing block gripper shoe;
2), when swing arm bearing pin changed by needs, make swing arm pin shaft part run to two axletree bearing peaks, with steel cable bottle gouard moved by hands, dynamic beam is fixed, makes swing arm bearing pin just to the position of circular hole in gripper shoe;
3) adopt and open circular hole place at gripper shoe gas cutting the dismounting hinge pin of abrasion deformation is taken out, clear up axis hole, then new new swing arm bearing pin is installed.
The conveniently replacing of swing arm bearing pin, when not affecting gripper shoe intensity, Circularhole diameter that gripper shoe is opened is greater than pin diameter 30 ~ 50mm.
Adopt the inventive method, can conveniently change swing arm bearing pin, replacing used time activity duration can complete in less than 8 hours, saves a large amount of non-cutting times, saves human and material resources, the more important thing is and do not affect production, make it create larger benefit.
Accompanying drawing explanation
Accompanying drawing is the running orbit schematic diagram of step rate swing arm bearing pin of the present invention.
In figure 1: step rate promotes swing arm, 2: bearing, 3: eccentric shaft, 4: bearing block gripper shoe, 5: bearing pin, 6: oscillating motor, 8: dynamic beam, 9: perforate.
Detailed description of the invention
Below in conjunction with accompanying drawing, the inventive method is elaborated:
As shown in the figure, get during step rate steel coil transportation volume be by step rate pendulum rises hydraulic cylinder 6 stretch out drive step rate promote swing arm 1 make step rate eccentric shaft 3 lifting in rotation, step rate move beam 8 rising get volume; When running to next volume position, step rate pendulum rises hydraulic cylinder 6 and retracts, and drive step rate to promote swing arm 1 and step rate eccentric shaft 3 is declined in rotation, step rate moves beam 8 decline and unreels fixing volume position.In whole service process, bearing pin is easy to wearing and tearing, and the bearing pin of damage needs to change in time, not so can cause whole baling line stopping production accident.
Replacing options of the present invention is as follows:
1) swing arm bearing pin 5 running orbit is first determined, the position of swing arm bearing pin respective shaft bearing gripper shoe 4 when two axletree bearing peaks, with gas cutting perforate 9 on this position of bearing block gripper shoe 4;
2), when swing arm bearing pin changed by needs, make swing arm pin shaft part run to two axletree bearing peaks, with steel cable bottle gouard moved by hands, beam 8 is moved to step rate and be fixed, make swing arm bearing pin 5 just to perforate 9 position in bearing block gripper shoe 4;
3) at the tapping of bearing block gripper shoe 4, the bearing pin 5 of abrasion deformation and oscillating bearing 2 are dismantled taking-up, cleaning axis hole, then installs new swing arm bearing pin 5, the oscillating bearing 2 simultaneously more renewed;
The conveniently replacing of swing arm bearing pin, when not affecting bearing block gripper shoe semi-finals degree, bearing block gripper shoe 4 perforate 9 diameter is greater than swing arm bearing pin 5 diameter 30 ~ 50mm.
Claims (2)
1. a step rate swing arm bearing pin quick change method, is characterized in that:
1) first determine swing arm bearing pin running orbit, when swing arm pin shaft part runs to two axletree bearing peaks, determine the position of swing arm bearing pin respective shaft bearing gripper shoe, circular hole is opened with gas cutting in this position of bearing block gripper shoe;
2) when swing arm bearing pin changed by needs, make swing arm pin shaft part run to two axletree bearing peaks, with steel cable bottle gouard moved by hands, dynamic beam is fixed, make swing arm bearing pin just to the position of circular hole in bearing block gripper shoe;
3) adopt and open circular hole place at bearing block gripper shoe gas cutting the dismounting hinge pin of abrasion deformation is taken out, clear up axis hole, then new swing arm bearing pin is installed.
2. a kind of step rate swing arm bearing pin quick change method according to claim 1, it is characterized in that, Circularhole diameter that gripper shoe is opened is greater than pin diameter 30 ~ 50mm.
