Abstract
The utility model relates to shipbuilding industry crankshaft hanger.The vertical suspender of a kind of Large Crankshaft, its main body is suspension rod and bearing pin, during use, suspension rod is loaded the assigned address of No. 1 crank opening of bent axle, bearing pin is inserted into the pin-and-hole location of suspension rod from crankshaft flange, get final product handling bent axle after hanging up properly lifting rope, there is simple to operate, that safety is high feature.
Description
Technical field
The utility model relates to a kind of suspender, particularly shipbuilding industry crankshaft hanger.
Background technology
In shipbuilding industry, during the vertical handling of low speed diesel engine bent axle, adopt centre hole that the mode (Fig. 1) of suspension ring is installed.Tens tons that the weight of each model low speed diesel engine bent axle is little, large reach ton up to a hundred, only have suspension ring to bear the weight of whole bent axle, there is security risk.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of easy to operate, the vertical suspender of safe and reliable Large Crankshaft.
The technical scheme that the utility model solves this technical problem employing is: the vertical suspender of a kind of Large Crankshaft, main body is a suspension rod and a bearing pin, be the rhombus slab of plane up and down in the middle of suspension rod, its Thickness Ratio crank opening is little, there is a pin-and-hole consistent with the center hole size of bent axle the centre of rhombus, and two ends have two to be an overall cylindrical hanger with rhombus slab.Bearing pin is the major axis that a diameter is less than central hole of the crankshaft, and its length can be inserted from crankshaft flange centre hole, run through suspension rod pin-and-hole, No. 1 crank center hole.
What suspension rod level put into No. 1 crank opens shelves, and suspension rod pin-and-hole and central hole of the crankshaft are placed as concentric position, and bearing pin inserts from the centre hole of bent axle upper flanges, run through the upper flanges of bent axle, suspension rod pin-and-hole, No. 1 crank, suspension rod is located.There is the step larger than central hole of the crankshaft the upper end of bearing pin, can not drop out after bearing pin is inserted from central hole of the crankshaft.Two lifting ropes are hung on the two ends hanger of suspension rod, and lifting rope upper end hangs on suspension hook, complete suspender installation and can start bent axle of vertically slinging.
On the rhombus of suspension rod plane and No. 1 crank open a grade plane contact, make the weight distribution of bent axle on the contact surface of suspension rod, two ends hanger has shared the weight of bent axle, improves the safety of suspender.

In Fig. 2 ~ 4: 1. lifting rope, 2. bearing pin, 3. suspension rod, 4. bent axle, 5. flange, 6. No. 1 crank, 7. hanger, 8. rhombus slab, 9. pin-and-hole.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As Fig. 2 ~ 4, that suspension rod (3) level is put into bent axle (4) No. 1 cranks (6) opens shelves, and the pin-and-hole (9) of suspension rod (3) is placed into the position concentric with bent axle (4) centre hole, the upper plane of rhombus slab (8) of suspension rod (3) is attached to crank opening inner plane, then upper flanges (5) centre hole of bearing pin (2) from bent axle is inserted, and run through flange (5), the pin-and-hole (9) of suspension rod (3), No. 1 crank (6), until one end of bearing pin (2) step larger than central hole of the crankshaft blocks.
Be hung on suspension rod (3) two ends hanger (7) by two lifting ropes (1), lifting rope (1) upper end hangs on suspension hook, completes the installation of suspender, and crane can start lifting.
Suspension rod (3), bearing pin (2), lifting rope (1) only need be placed into assigned address by installation process, and operating process is simple.
Claims (1)
1. the vertical suspender of Large Crankshaft, main body is suspension rod and bearing pin, it is characterized in that: be rhombus slab in the middle of suspension rod, two ends and rhombus slab are two overall cylindrical hangers, there are one and central hole of the crankshaft pin-and-hole of the same size in the center of rhombus slab, bearing pin is the axle that a diameter is less than central hole of the crankshaft, and length can run through crankshaft flange, suspension rod and No. 1 crank, and there is the step larger than central hole of the crankshaft one end of bearing pin.
