Abstract
A kind of bogie hinged bolts liftout attachment, it is characterised in that：Including footstock, positioning tube and hydraulic cylinder, footstock is formed by connecting by forward and backward two pieces of risers, one block plate of lower part, and hydraulic cylinder is located on the inside of the front vertical plate of footstock, and positioning tube is connected behind hydraulic cylinder.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 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, and the bolt head being then ejected by clamp package extracts bolt, realizes the dismounting of the hinged bolts to 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 extracting tool, more particularly, to a kind of rail vehicle truck system articulation
The liftout attachment 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, and is first pushed up using liftout attachment
Go out bolt, then extracted with other instruments, realize the dismounting of the hinged bolts to being mounted on narrow space position.
To achieve the above object, the utility model provides a kind of bogie hinged bolts liftout attachment, it is characterised in that：
Including footstock, positioning tube and hydraulic cylinder, footstock is formed by connecting by forward and backward two pieces of risers, one block plate of lower part, and hydraulic cylinder is located at
On the inside of the front vertical plate of footstock, positioning tube is connected behind hydraulic cylinder.
The forward and backward riser and seat board junction is provided with several reinforcing ribs.
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, the bolt head being then ejected by clamp package extracts bolt, realizes the articulation to being mounted on narrow space position
The dismounting of hole bolt.It is simple and reliable, it is easy to operate.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
With reference to Fig. 1, specific embodiment of the present invention is by forward and backward two pieces of risers 1,6, lower part seat board 2,3 and of positioning tube
Hydraulic cylinder 4 forms.Forward and backward two pieces of risers 1,6, lower part seat board 2 also can integrally be cast, be forged with welding forming.Hydraulic cylinder is set
On the inside of front vertical plate, positioning tube is connected behind hydraulic cylinder.In the position of narrow space, back vertical plate is placed on to the screw rod side of bolt
Between adjacent component, positioning tube 3 is sleeved on bolt head, the connected piece for withstanding bolt rostral.In positioning tube 3 and front vertical plate
Hydraulic cylinder 4 is placed between 1.After the action of hydraulic cylinder 4, back vertical plate ejects the screw rod of bolt, until screw rod end face is with being connected
Part plane is substantially flush.Then the bolt head being ejected by clamp package extracts bolt, realizes narrow to being mounted on space
The dismounting of the hinged bolts of small position.It is simple and reliable, it is easy to operate.
