The utility model discloses can avoid equipment damage, extension coaster life reduces the accident rate, saves the material, reduces operation personnel intensity of labour.
Description
Technical Field
The utility model belongs to handling mechanical equipment field especially relates to a split type crane tow-cable coaster.
Background
A7 # blast furnace slag flushing two-row crane of an ironmaking head plant is positioned above an outdoor open slag pool for flushing slag, water vapor is evaporated all the year round, and corrosive steam severely erodes the crane and parts thereof. Because the tow cable coaster automobile body of original design is single thin, the project organization of integral type is unreasonable, and the slag flushing crane operating rate is very high in addition, and the tow cable coaster wearing and tearing, dragging in service lead to warping, jamming, often take place in the production operation in-process that the tow cable coaster falls the way, open welding, fracture, and the cable is dragged disconnected, and the trailing arm warp, open welding phenomenon. When in rush repair, a cable pulley, a butt cable, a welding correction trailing arm and the like need to be replaced, the time is 8-10 hours, the slag flushing safety production is seriously influenced, the production safety and smooth running of a blast furnace are threatened, and a large amount of manpower and materials are wasted. And the crane is above the slag bath, the space on the crane is narrow, and the potential safety hazard that personnel fall from high altitude still exists during operation.
The towing pulley of the slag flushing two-row crane is thinner in original design and easy to deform, a pulley sliding part on the upper part of the pulley and a cable dragging part on the lower part of the pulley are welded into a whole through a vertical fixing plate, the resistance of the design structure of the towing pulley is dragging, the resistance to pushing and squeezing is very poor, the skew dragging and slant dragging unbalanced force generated by back and forth dragging during operation often causes the pulley fixing plate to deform and damage, and then causes the towing pulley body to deform, damage and derail.
Disclosure of Invention
The utility model aims at providing a rational in infrastructure, the nimble swing about can, the fault rate is low, long service life, the split type crane tow-cable pulley of reducible maintenance work volume.
Therefore, the utility model discloses the technical solution who takes does:
a pulley sliding part and a cable dragging part of the towing pulley adopt a split structure; bolt holes are formed in the center of the bottom of a U-shaped connecting plate of a pulley sliding part and the center of the top of a rotating frame of a cable dragging part, a movable penetrating rod with a section of external thread on the upper portion is arranged in the bolt holes of the U-shaped connecting plate and the rotating frame, the upper portion of the penetrating rod is connected with the U-shaped connecting plate through a penetrating rod nut, pin holes are formed in the positions, corresponding to the penetrating rod nut, of the penetrating rod, split pins are arranged in the pin holes, gaskets are respectively arranged between the penetrating rod nut and the U-shaped connecting plate and between the rotating frame and a penetrating rod head, and; the pulley fixing plate with the pulley on the inner side is fixedly connected with the U-shaped connecting plate through a fastening bolt.
The utility model has the advantages that:
because the swivel mount can wear the pole and be rotatory for the axle, make cable drag portion can the horizontal hunting, offset the unbalanced force that "askew drawing inclined dragging" of crane in service to avoid equipment damage, extension coaster life reduces the accident rate. Before the implementation, more than 2 large or small accidents occur in each month on average, so that the emergency repair is frequently carried out, and a large amount of manpower and materials are wasted. After the improvement is implemented, the fault does not occur for more than one year, so that the material is saved, the labor intensity of workers is reduced, and the smooth production of blast furnaces and slag flushing procedures is ensured.
Drawings
FIG. 1 is a front view of a split crane streamer trolley;
fig. 2 is a left side view of a split crane streamer trolley.
In the figure: pulley fixed plate 1, fastening bolt 2, U type connecting plate 3, pulley 4, poling 5, poling nut 6, swivel mount 7, split pin 8, packing ring 9.
Detailed Description
As can be seen from the attached drawings 1 and 2, the utility model discloses split type crane tow-cable pulley mainly changes the project organization of the former integral type of tow-cable pulley into and adopts the components of a whole that can function independently structure with upper portion pulley sliding part and lower part cable dragging part. A bolt hole is formed in the center of a rotating frame 7 of the cable dragging portion, a movable penetrating rod 5 with an upper portion provided with a section of external thread is movably arranged in the bolt hole of the rotating frame 7, the upper portion of the penetrating rod 5 is connected with a U-shaped connecting plate 3 through a penetrating rod nut 6, and the rotating frame 7 rotates horizontally by taking the penetrating rod 5 as an axis. The pulley fixing plate 1 with the pulleys 4 on two sides is fixed on the U-shaped connecting plate 3 through the fastening bolts 2, the corresponding positions of the penetrating rod 5 and the penetrating rod nut 6 are provided with pin holes, and the pin holes are internally provided with split pins 8, so that the penetrating rod nut 6 can be prevented from being loosened, and the safety coefficient of connection is increased. Gaskets 9 are respectively arranged between the rod penetrating nut 6 and the U-shaped connecting plate 3 and between the rotating frame 7 and the rod head of the penetrating rod 5, so that the rotating frame 7 can rotate conveniently. The pulley fixing plate 1 with the pulley 4 on the inner side is fixedly connected with the U-shaped connecting plate 3 through the fastening bolt 2.
Simultaneously, for reinforcing tow-cable coaster intensity, improve tow-cable coaster life, the utility model discloses a strengthened pulley 4's big or small diameter, increaseed 90mm and 77mm to big diameter and minor diameter by original 82mm and 69mm respectively. Secondly, the thickness of the steel plate of the pulley fixing plate 1 is increased from 3mm to 5 mm. Thirdly, the specification of connecting bolts such as cable fixing bolts is properly increased.
