Abstract
Pantograph air bag limiting bracket be by：The compositions such as lifter stent, rotary shaft, position-limited rack, air bag, limiting square tube, after-poppet.Pantograph air bag limiting bracket provided by the utility model, it is improving and optimizating on original airbag lift device bracket basis, while reducing the cross dimensions of square tube, increase Impact direction upper reinforcing plate, expand the spatial joint clearance of air bag both sides, so as to efficiently solve it is each to friction and touching, ensure pantograph control is normal and the safety of electric locomotive.
Description
Technical field
The utility model is related to the air spring assemblies of high-speed and common-speed railway electric locomotive pantograph, and in particular to by electricity
Bend air bag limiting bracket.
Background technology
Pantograph air bag is the critical component that lifting drive is provided to pantograph, is commonly called as air spring, air bag is basic at present
On be by external import, the flexible of air bag inflation/deflation carrys out passing power by lifter stent, and impulse stroke has limiting to fill
It puts, space is extremely limited in stroke, and the hinge means of anti-buckling deformation is equipped in airbag chamber, is laterally freely
Deformation since pneumatophore is rubber synthetic products, with Universal deformable, can allow for the ectosome of air bag and left and right caging bolt in this way
It is easy to rub, while also with air-bag support touching and friction occur for the limiting square tube of lifter stent, make pantograph
Control system goes wrong, and seriously affects the normal operation of electric locomotive, and part sky can no doubt be provided by reducing the size of square tube
Between, but the rigidity of limiting bracket can be made to die down, the performance fault of whole device can be caused after deforming.
Utility model content
Pantograph air bag limiting bracket provided by the utility model is the improvement on original airbag lift device bracket basis
Optimization while reducing the cross dimensions of square tube, increases Impact direction upper reinforcing plate, expands the spatial joint clearance of air bag both sides, from
And efficiently solve it is each to friction and touching, ensure pantograph control is normal and the safety of electric locomotive.
The technical solution of the utility model is：Pantograph air bag limiting bracket be by：Lifter stent, rotary shaft, limiting
The compositions such as frame, air bag, limiting square tube, after-poppet.The lifter stent is assemblied in by fixing bolt on air bag, can be with air bag
Flexible and rotation and move；Position-limited rack is assemblied in also by fixing bolt on air bag, can be moved with the rotation of air bag, limiting
The limiting square tube movement of frame lifter stent open shelves between, and the row that the length limitation air bag for passing through two bolts stretches
Journey；The air bag is assembled on the rotary shaft by the mounting hole of after-poppet, can be rotated around the axis of rotation, and by airbag chamber inner hinge
Limitation directional expansion stretch.
Since motorcycle pantograph can dynamically be vibrated during high-speed cruising by a high frequency, the air bullet of pantograph
Spring device --- position-limited rack and lifter stent are nearer due to mutual spacing, it is easy to friction and touching occur, company is made when serious
Fitting and air bag abrasion, can make the improper automatic bow-lowering of motorcycle pantograph, locomotive stop transport and accident of locomotive defect occurs, due to this practicality
The Optimal improvements of novel limiting frame greatly reduce the probability of this abrasion, so as to ensure the safety of high-speed railway locomotive operation；
It is the utility model structure novel, compact, reasonable, effectively overcome the friction problem during movement of traditional structure component working, peace
It is complete reliable.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
In Fig. 1：It is propped up after 1-- lifters stent, 2-- rotary shafts, 3-- position-limited racks, 4-- air bags, 5-- limitings square tube, 6--
Frame.
Specific embodiment
The utility model is described in more detail below in conjunction with the accompanying drawings.
In Fig. 1：Pantograph air bag limiting bracket is by lifter stent 1, rotary shaft 2, position-limited rack 3 and air bag 4, limiting side
Pipe 5, after-poppet 6 form, and air bag 4 expands expansion after inflating, in the limiting of the hinge combined mechanism of 4 intracavitary of rotary shaft 2 and air bag
Under, lifter stent 1 is moved in a manner of surrounding rotary shaft 2 and rotating and extend (polar curve), so as to push pantograph
Double leval jib action, for control pantograph by speed and the curve lifting of setting, position-limited rack 3 is operated in the centre of lifter stent 1
With the outside of air bag 4, during the expansion of air bag 4 is flexible, the left and right deformation of air bag 4 is easily touched with the friction of the bolt of position-limited rack 3
It touches, position-limited rack 3 is easily touched again with lifter stent 1, and improved position-limited rack 3 reduces the size of square tube, increases stress side
To strengthening version increase the pitch-row of caging bolt simultaneously, that is, increase air bag deformation allow space, make long-term ask
Topic is addressed.
Claims (1)
1. pantograph air bag limiting bracket, be by：Lifter stent, rotary shaft, position-limited rack, air bag, limiting square tube, after-poppet etc.
It forms, it is characterised in that：Lifter stent is assemblied in by fixing bolt on air bag, can be transported with the flexible and rotation of air bag
Dynamic, position-limited rack is assemblied in also by fixing bolt on air bag, can be moved with the rotation of air bag, the limiting square tube movement of position-limited rack
Lifter stent open shelves between, and the stroke that the length limitation air bag for passing through two bolts stretches, the air bag pass through rear
The mounting hole assembling of stent on the rotary shaft, can rotate around the axis of rotation, and limited directional expansion by airbag chamber inner hinge and stretched
Contracting.
