Abstract
A kind of bogie hinged bolts disassembling fixture, it is characterised in that：Including a liftout attachment and a pulling device, liftout attachment is placed between the screw rod side of bolt and adjacent component, the screw rod for outside liftout bolt；Pulling device parcel has been ejected the bolt head of device ejection and has thoroughly extracted bolt.Positioning tube is enclosed on bolt head, withstands the connected piece of bolt rostral by the present invention by the way that the back vertical plate of footstock in liftout attachment is placed between the screw rod side of bolt and adjacent component.After hydraulic cylinder action, the back vertical plate of footstock ejects the screw rod of bolt, the bolt head that device ejects has been ejected by two valve fixture make-ups, parcel in pulling device again, two valve fixtures of make-up are pulled by hydraulic cylinder and screw rod, nut, fixture is set to be moved in guide cylinder, most bolt is thoroughly extracted at last.Liftout attachment and pulling device collective effect, on the premise of hinged bolts are not destroyed, the hinged bolts installed in narrow space position are dismantled.It is simple and reliable, it is easy to operate.
Description
Technical field
The invention belongs to track traffic disassembling fixture, more particularly, to a kind of rail vehicle truck system articulation hole spiral shell
The disassembling fixture of bolt.
Background technology
At present, on bogie some limited spaces position, in order to realize assembling connecting piece in larger shearing force
Under do not loosen, employ hinged bolts, as single stage suspension be herringbone India-rubber spring lifting boom fixing bolt and motor
Resilient hanger fixing bolt.But the position being limited in these operating spaces, dismounting hinged bolts are one extremely difficult
Thing, it is often necessary to which destroying bolt could complete.
The content of the invention
It is an object of the invention to provide one kind on the premise of hinged bolts are not destroyed, it is set with using ejecting and pulling two
The mode being applied in combination is put, the hinged bolts installed in narrow space position are dismantled.
To achieve the above object, the present invention provides a kind of bogie hinged bolts disassembling fixture, it is characterised in that：Including
One liftout attachment and a pulling device, liftout attachment are placed between the screw rod side of bolt and adjacent component, for outwards ejecting spiral shell
The screw rod of bolt；Pulling device parcel has been ejected the bolt head of device ejection and has thoroughly extracted bolt.
Described liftout attachment is made up of footstock, positioning tube and hydraulic cylinder, and footstock is by forward and backward two pieces of risers, bottom one
Block plate is formed by connecting, and hydraulic cylinder is located on the inside of the front vertical plate of footstock, and positioning tube is connected behind hydraulic cylinder.
Described forward and backward riser and seat board junction is provided with some reinforcements.
Described pulling device is by two valve fixtures, a screw rod, two hex nuts, a guide cylinder and hollow hydraulic cylinder
Composition, hollow hydraulic cylinder connection guide cylinder, screw rod are placed in two valve fixtures through hollow hydraulic cylinder and guide cylinder, and both ends pass through
Hex nut limiting locking is on the inside of hollow hydraulic cylinder side and two valve fixtures.
Positioning tube is enclosed on by the present invention by the way that the back vertical plate of footstock is placed between the screw rod side of bolt and adjacent component
Bolt head, the connected piece for withstanding bolt rostral.After hydraulic cylinder action, the back vertical plate of footstock ejects the screw rod of bolt,
The bolt head that device ejects is ejected by two valve fixture make-ups, parcel again, by hydraulic cylinder and screw rod, that nut pulls is right
Two valve fixtures of button, make fixture be moved in guide cylinder, most bolt is thoroughly extracted at last.Liftout attachment and pulling device it is common
Effect, on the premise of hinged bolts are not destroyed, using ejecting and pull by the way of two covering devices are applied in combination, to installed in
The hinged bolts of narrow space position are dismantled.It is simple and reliable, it is easy to operate.
Brief description of the drawings
Fig. 1, Fig. 2 are the liftout attachment schematic diagrames of the present invention；
Fig. 3, Fig. 4 are the pulling device schematic diagrames of the present invention.
Embodiment
Reference picture 1, Fig. 2, specific embodiment of the invention liftout attachment 1 are made up of footstock, positioning tube 3 and hydraulic cylinder 4 etc..
Footstock is made up of forward and backward two pieces of risers 5,6, the block plate 2 of bottom one and six reinforcements 7, can be with welding forming, also can be integral
Casting, forging form.Hydraulic cylinder is located on the inside of the front vertical plate of footstock, and positioning tube is connected behind hydraulic cylinder., will in the position of narrow space
The back vertical plate of footstock is placed between the screw rod side of bolt and adjacent component, and positioning tube 3 is enclosed on into bolt head, withstands bolt head
The connected piece of side.Hydraulic cylinder 4 is placed between the front vertical plate of positioning tube 3 and footstock 2.After the action of hydraulic cylinder 4, footstock 2
Back vertical plate ejects the screw rod of bolt, until screw rod end face is substantially flush with connected piece plane.
Reference picture 3, Fig. 4, pulling device 5 is by two valve fixture 11, one, 8, guide cylinders of hex nut of screw rod 12, two
9 and hollow hydraulic cylinder 10 form.Hollow hydraulic cylinder connects guide cylinder, and screw rod is placed in two valves through hollow hydraulic cylinder and guide cylinder
In fixture, both ends are by hex nut limiting locking on the inside of hollow hydraulic cylinder side and two valve fixtures.Pass through two valve fixtures 11
Make-up, parcel have been ejected the bolt head of the ejection of device 1, then pull the two of make-up by hydraulic cylinder 10 and screw rod 12, nut 8
Valve fixture 11, fixture is set to be moved in guide cylinder 9, most bolt is thoroughly extracted at last.
