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, for the screw rod of outside liftout bolt；Pulling device package has been ejected the bolt head of device ejection and has thoroughly extracted bolt.The utility model is sleeved on bolt head, the connected piece for withstanding bolt rostral 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, by positioning tube.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, package in pulling device again, two valve fixtures of make-up are pulled by hydraulic cylinder and screw rod, nut, fixture is made 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, are dismantled the hinged bolts for being mounted on narrow space position.It is simple and reliable, it is easy to operate.
Description
Technical field
The utility model belongs to track traffic disassembling fixture, more particularly, to a kind of rail vehicle truck system articulation
The disassembling fixture of hole 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.
Utility model content
The purpose of this utility model is to provide one kind on the premise of hinged bolts are not destroyed, using ejection and pulling two
The mode that covering device is applied in combination dismantles the hinged bolts for being mounted on narrow space position.
To achieve the above object, the utility model provides 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, for outwards pushing up
Go out the screw rod of bolt；Pulling device package has been ejected the bolt head of device ejection and has thoroughly extracted bolt.
The liftout attachment is made of footstock, positioning tube and hydraulic cylinder, and footstock is by forward and backward two pieces of risers, lower part 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.
The forward and backward riser and seat board junction is provided with several reinforcing ribs.
The 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 through hollow hydraulic cylinder and guide cylinder in two valve fixtures, and both ends pass through
Hex nut limiting locking is on the inside of hollow hydraulic cylinder side and two valve fixtures.
The utility model is by the way that the back vertical plate of footstock is placed between the screw rod side of bolt and adjacent component, by positioning tube
It is sleeved on bolt head, the connected piece for withstanding bolt rostral.After hydraulic cylinder action, the back vertical plate of footstock is by the screw top of bolt
Go out, then the bolt head that device ejects has been ejected by two valve fixture make-ups, package, pulled by hydraulic cylinder and screw rod, nut
Two valve fixtures of make-up, make fixture 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, by the way of ejecting and pulling two covering devices and be applied in combination, to peace
Hinged bolts mounted in narrow space position are dismantled.It is simple and reliable, it is easy to operate.
Description of the drawings
Fig. 1, Fig. 2 are the liftout attachment schematic diagrames of the utility model；
Fig. 3, Fig. 4 are the pulling device schematic diagrames of the utility model.
Specific embodiment
With reference to Fig. 1, Fig. 2, specific embodiment of the present invention liftout attachment 1 is by footstock, positioning tube 3 and hydraulic cylinder 4 etc.
Composition.Footstock is made of forward and backward two pieces of risers 5,6, one block plate 2 of lower part and six reinforcing ribs 7, can with welding forming,
It can integrally cast, forge.Hydraulic cylinder is located on the inside of the front vertical plate of footstock, and positioning tube is connected behind hydraulic cylinder.In narrow space
The back vertical plate of footstock is placed between the screw rod side of bolt and adjacent component by position, and positioning tube 3 is sleeved on bolt head, top
The firmly connected piece of bolt rostral.Hydraulic cylinder 4 is placed between the front vertical plate of positioning tube 3 and footstock 2.After the action of hydraulic cylinder 4,
The back vertical plate of footstock 2 ejects the screw rod of bolt, until screw rod end face is substantially flush with connected piece plane.
With reference to Fig. 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, package 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 makes fixture be moved in guide cylinder 9, and most bolt is thoroughly extracted at last.
