Abstract
The utility model belongs to the field of elastic pin detachment tools, and particularly relates to a tool special for detaching an elastic pin coupling. The tool special for detaching the elastic pin coupling comprises a stud and ejector rod nuts. The two ends of the stud are provided with the ejector rod nuts respectively. A slide way type accessory device is welded to the two ejector rod nuts. A blind hole is formed in an end of the ejector rod nut at one end of the stud. The tool has the advantages that independent operation can be achieved, labor is saved, and the tool is safe and more convenient to overhaul and replace.
Description
Technical field
The utility model belongs to spring column pin extracting tool field, is specifically related to a kind of flexible pillar pin coupling removal tool special.
Background technology
Locomotive is in practice, and crew often finds in locomotive servicing operation and station stop patrolling and examining that accessory drive is indoor a rubber smell, checks that through maintainer finding is because the impact rotatablely moving frequently makes rubber ring friction scaling loss.But the rubber ring of changing flexible pillar pin coupling must be dismantled again spring column pin, dismounting spring column pin needs special disassembling fixture overcome the stiction between pin and driven flange.
The instrument of traditional dismounting spring column pin is in the upkeep operation of locomotive, and the instrument that maintainer uses will, in overcoming when dismounting axial compressive force of producing of spring column pin, also will overcome the spin friction power that instrument itself produces.In the time using conventional tool dismounting spring column pin, easily there is the relative sliding between frock and pin, occur that frock collapses the phenomenon, and causes hidden danger; Before dismounting starts, use traditional extracting tool that the situation that frock falls down easily occurs, and in the time that changing shaft coupling rubber ring, locomotive inspection and repair operation at least needs two people's cooperative jobs, working space between accessory drive is narrower and small, sometimes also need with crowbar, hand hammer etc., field operation workman's labour intensity is high, has affected to a certain extent the normal overhaul efficiency of locomotive.For this reason, all kinds of factors such as the dangerous and workman's who occurs under the pressure of above service work labour intensity height, require us to be improved traditional extracting tool, under the premise that security is guaranteed, raising overhaul efficiency, reduces labour intensity as far as possible, shortens the shaft coupling spring column pin take-down time, change in time rubber ring, ensure the normal operation of auxiliary transmission section.
Utility model content
The utility model, in order to make up the defect of prior art, provides one can realize independent operation, laborsaving and safety, makes maintenance change convenient flexible pillar pin coupling removal tool special.
The utility model is achieved by the following technical solution:
A kind of flexible pillar pin coupling removal tool special, comprise studs and push rod nut, push rod nut is equipped with respectively at described studs two ends, on two push rod nuts, is welded with chute type auxiliary equipment, and the described studs wherein push rod nut end of one end has blind hole.
Further, described chute type auxiliary equipment is made up of connecting rod, support bar and slideway, and support bar end is welded with slideway, the connecting rod cross break shape that meets at right angles, and be connected in the slideway of support bar end.
Further, described support bar and connecting rod are made by round steel, and slideway is made up of seamless steel pipe.
The beneficial effects of the utility model are: the axial thrust that a kind of flexible pillar pin coupling removal tool special of the utility model utilizes worm drive to produce overcomes the frictional force between pin and driven flange, make full use of the cooperation of the positive and negative silk of studs, overcome the spin friction problem that instrument and spring column pin produce in the time of dismounting, spin friction is changed into relative static friction, prevent that so to a certain extent conventional tool is because of spin friction, make instrument collapse the generation of phenomenon, chute type auxiliary equipment can be realized a people and operate separately, save muscle power, in the blind hole of the push rod nut end of one end of frock, can stop to dismantle initial frock and fall down the appearance of phenomenon, operate safer, the axiality of two weeks importantly can ensure to install time, improve to a certain extent the service life of rubber ring, new frock is in the various shortcomings of the appearance that overcomes traditional frock, use and can realize independent operation, laborsaving and safety, maintenance is changed convenient.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is the utility model assembling schematic diagram.
In figure, 1 studs, 2 push rod nuts, 3 chute type auxiliary equipments, 4 slideways, 5 blind holes, 6 connecting rods, 7 support bars, 8 motors, 9 driven flanges, 10 spring column pins.
Detailed description of the invention
Accompanying drawing 1-2 is a kind of specific embodiment of the present utility model.A kind of flexible pillar pin coupling removal tool special of this utility model, comprise studs 1 and push rod nut 2, push rod nut 2 is equipped with respectively at described studs 1 two ends, on two push rod nuts 2, be welded with chute type auxiliary equipment 3, described studs 1 wherein push rod nut 2 ends of one end has blind hole 5.
Further, described chute type auxiliary equipment 3 is made up of connecting rod 6, support bar 7 and slideway 4, and support bar 7 ends are welded with slideway 4, the connecting rod 6 cross break shape that meets at right angles, and be connected in the slideway 4 of support bar 7 ends.
Further, described support bar 7 and connecting rod 6 are made by round steel, and slideway 4 is made up of seamless steel pipe.
A kind of flexible pillar pin coupling removal tool special of the utility model, when use, this frock is assembled between motor 8 and driven flange 9, make the push rod nut 2 that has blind hole 5 one end nullify 10 assemblings with the elasticity on driven flange 9, the appearance that can stop to dismantle initial frock and fall down phenomenon, operates safer.
The utility model is not limited to above-mentioned embodiment, anyone should learn under enlightenment of the present utility model, make with the utlity model has identical or close technical scheme, within all falling into protection domain of the present utility model.
Technology, shape, structure part that the utility model is not described in detail are known technology.
