Abstract
The utility model discloses an internal combustion engine piston special hoisting tool, which comprises a top rod, a hoisting sleeve and two top rod supporting parts with screw holes; the propping rod is fixedly provided with a screw cap; one end of the top rod is provided with an inverse external thread and the other end is provided with a left-handed external thread; the hoisting sleeve is arranged between the screw cap of the top rod and the external thread at one end; the hoisting sleeve is provided with a hoisting cable through hole and a top rod through hole; the screws of the top rod supporting parts are respectively matched with the inverse and positive external threads at two ends of the top rod. The utility model can largely improve the working efficiency when hoisting the internal combustion engine piston, and is convenient for the operation of the maintenance personnel, and ensures the safety when hoisting the internal combustion engine piston.
Description
Technical field
The utility model relates to a kind of diesel locomotive maintenance specialized equipment, particularly a kind of diesel locomotive piston special hanger.
Background technology
In the prior art, when lifting diesel locomotive piston, all be the service personnel manual operations, when the lifting piston, must withstand piston rod with waddy by the sighthole of diesel engine, and will constantly carry out jiggering, like this in order that borrow the strength of bent axle, the strut member of bent axle as waddy, the tilting connecting rod ejects cylinder sleeve to piston, when piston exposes cylinder sleeve, ties piston with rope again piston is extracted, therefore work efficiency is low, and very dangerous to service personnel during operation.
Summary of the invention
Technical problem to be solved in the utility model is the diesel locomotive piston special hanger that a kind of mechanization is provided for the problem that overcomes inefficiency hand-manipulated, the technical scheme that it adopts is: a kind of diesel locomotive piston special hanger, it comprises a push rod, be set with nut on the push rod, one end of push rod has the outside thread of setting one's teeth on edge, and the other end has along the tooth outside thread; A lifting cover, this lifting cover be installed on the push rod nut and wherein between the outside thread of an end, lifting is overlapped and is provided with hoist cable through hole and push-rod hole; Two push rod strut members that have screw, its screw are complementary along the tooth outside thread with falling of push rod two ends respectively.
The beneficial effects of the utility model are: make things convenient for mechanized, after having used diesel locomotive piston special hanger now, need not manually to carry out jiggering and tilting connecting rod, as long as earlier crankshaft disk behind topmost, make piston reach first dead center, then the piston special hanger is placed in the groove of piston head, the push rod nut of rotating piston special hanger again, the push rod strut member is stuck in below the interior edge of piston head, after waiting to tighten, with sling lifting cover of steel rope, just can from cylinder sleeve, pull out piston and directly hang out piston then, install and also to have made things convenient for manyly, the work efficiency when having improved lifting diesel locomotive piston greatly makes things convenient for the operation of service personnel and the safety when guaranteeing to lift the diesel locomotive piston simultaneously.Therefore not only saved time when using the utility model lifting diesel locomotive piston, laborsaving but also guaranteed safety.

The specific embodiment
The utility model is described in further detail below with reference to accompanying drawing 1 to accompanying drawing 4b:
As shown in Figure 1, a kind of diesel locomotive piston of the utility model special hanger comprises: a push rod 1, be set with nut 11 on the push rod 1, and an end of push rod 1 has the outside thread of setting one's teeth on edge, and the other end has along the tooth outside thread; A lifting cover 2, this lifting cover 2 be installed on the push rod 1 nut 11 and wherein between the outside thread of an end, lifting is overlapped 2 and is provided with hoist cable through hole 21 and push-rod hole 22; Two push rod strut members 3 that have screw 31, its screw 31 are complementary along the tooth outside thread with falling of push rod 1 two ends respectively.
Also be provided with the pin-and-hole 12 and the pin 13 that are used to limit lifting cover position on the described push rod 1.
Described push rod strut member 3 cross section semicirculars in shape.
When in practical operation, using the utility model lifting piston, earlier will be behind topmost crankshaft disk, make piston reach first dead center, then the piston special hanger is placed in the groove of piston head, the push rod nut 11 of rotating piston special hanger is regulated the distance between two push rod strut members 3 again, push rod strut member 3 is stuck in below the interior edge of piston head, after waiting to tighten, with the steel rope lifting cover 2 of slinging, just can from cylinder sleeve, pull out piston.
Claims (4)
1. diesel locomotive piston special hanger is characterized in that comprising:
