Description
Technical field
Floor push field the invention belongs to be used for driver's control, is related to a kind of lifting drive of floor push.
Background technology
At present, the floor push for being used on the domestic locomotive of China is divided according to function, generally there is two types：
One type is that only possess vigilant function, and its general principle is that vigilant floor push is entered within the certain hour cycle
Row is jammed on, and to confirm that locomotive driver and conductor is in good working state, once not temporally cycleoperation, device forces alarm
Train Stopping.The type does not consider driver and conductor's height, size difference, it is impossible to adjust floor push highly, comfortableness is poor.
Another type be provided simultaneously with vigilant function and with other miscellaneous functions, pedal elevating function is wherein important
One.Domestic high ferro and EMUs requirement floor push not only consider traffic safety, with vigilant function, also increasingly emphasize
Comfort, possesses pedal lift adjustment function, therefore the floor push of type is used increasingly in high ferro and motor-car
Increase.The lifting of the type pedal drives usually using motor, simple structure, but motor drives and needs external drive power supply, will
Increase the complexity of circuit, also bring along certain energy loss, meanwhile, motor can also take certain space, cause product chi
It is very little larger, bigger installing space is required during installation.
The content of the invention
Need external drive power supply and cause complex circuit, product size larger to solve above-mentioned existing floor push
Problem, the present invention proposes that a kind of inside carries the lifting drive of the floor push of driving source.
Technical solution of the invention is：The lifting drive of the floor push for being provided includes trigger mechanism and liter

It is about to bracing wire displacement, bracing wire displacement will be driven by bracing wire fixation board component under above-mentioned Height Adjustment button stress
Bracing wire fixture block presses gas spring triggering end, and gas spring unlocks function, if guide pad does not receive external force, gas spring piston
Bar stretches out, and link gear drive guide pad moves up pedal；If applying external force acts on foot-operated plate surface, guide pad band
Dynamic link gear, makes gas spring piston rod forced contraction, pedal height reduction.When pedal moves to required position,
Unclamp Height Adjustment button be lockable pedal highly.
Board component is fixed in above-mentioned bracing wire can multiple structural forms, preferably with leverage, i.e. bracing wire fixed plate
Component includes fixed mount and lever, and fixed mount is fixed on floor push body, and the center of lever is hinged on fixed mount, lever
One end be provided with roller, be connected with bracing wire for the other end with Height Adjustment snap fit, lever.
Further improving is：Bracing wire is fixed and is additionally provided with for adjusting the elastic bracing wire nut of bracing wire and being used on board component
The locking nut of bracing wire is locked, bracing wire nut is stuck in the draw-in groove of fixed mount, bracing wire nut and locking nut connect with bracing wire screw thread
Connect.
Above-mentioned link gear can drive guide pad to move using Timing Belt, i.e.,：Link gear includes connecting rod and cunning
Wheel group, assembly pulley includes movable pulley and fixed pulley；Connecting rod is hinged on floor push body at its center, one end of connecting rod with
Gas spring piston rod is hinged, and the other end is provided with movable pulley, and fixed pulley is arranged on floor push body, is placed with assembly pulley
Timing Belt, the two ends of synchronous pulley are connected respectively at two guide pads.The assembly pulley and Timing Belt can also use sprocket wheel and chain
Bar is substituted.
In order that pedal is moved up and down more steadily, described fixed pulley and guide pad is preferably arranged symmetrically.
It is an advantage of the invention that：The lift drive mechanism of floor push, as driving source, is realized using air pressure inside spring
Pedal height adjustable, whole device is integrated in inside floor push, save space.

Specific embodiment
The embodiment for being given below in conjunction with the accompanying drawings is described in detail to the present invention：
Referring to Fig. 1, this lifting drive includes trigger mechanism and elevating mechanism；Trigger mechanism includes Height Adjustment button
1st, board component 2, bracing wire 3 and bracing wire fixture block 4 are fixed in bracing wire；Elevating mechanism includes gas spring 5, link gear and two guide pads
7；Link gear includes connecting rod 8 and assembly pulley, and assembly pulley includes a movable pulley 9 and several fixed pulleys 10, and assembly pulley is provided with
Timing Belt 6, the two ends of Timing Belt are connected with two guide pads 7, and guide pad 7 is connected with pedal.
Referring to Fig. 2, board component 2 is fixed in above-mentioned bracing wire includes fixed mount 12 and lever 11, and fixed mount 12 is fixed on foot-operated opening
Close on body, the center of lever is hinged on fixed mount, and one end of lever is provided with roller, and roller is contacted with Height Adjustment button 1,
The other end of lever is connected with one end of bracing wire 3, and the other end of bracing wire is connected with one end of bracing wire fixture block 4, bracing wire fixture block 4 it is another
One end is hinged on floor push body.
Bracing wire is fixed and is additionally provided with board component 2 for adjusting the elastic bracing wire nut 13 of bracing wire and lock for locking bracing wire
Tight nut 14, bracing wire nut 13 is stuck in the draw-in groove of fixed mount 12, and bracing wire nut 13 and locking nut 14 connect with the screw thread of bracing wire 3
Connect.Bracing wire nut 13 is used to adjust the elastic state of bracing wire 3 manually, and locking nut 14 can prevent bracing wire 3 from using
Relaxation of deformation in journey, so as to cause trigger mechanism effective travel to shorten, causes pedal normally to lift the generation of problem, really
Protect the normal lifting of floor push.
The triggering end of above-mentioned gas spring 5 is contacted with bracing wire fixture block 4, and the piston end of gas spring 5 cuts with scissors with one end of connecting rod 8
Connect, the center of connecting rod is hinged on floor push body, the other end of connecting rod is provided with movable pulley 9, and fixed pulley 10 is arranged on pin
Step on Switch main body.When connecting rod is rotated by piston rod thrust, can make to be moved on movable pulley 9, be driven on guide pad 7 by Timing Belt 6
Move, pedal is moved on.
Fixed pulley and guide pad 7 are arranged symmetrically, and contribute to pedal more steady in lifting process.
Assembly pulley and Timing Belt 6 also can use the driving members such as sprocket wheel and chain to replace.
The present apparatus is to realize that pedal is lifted by driving element gas spring 5, can be locked pedal as needed
The position needed for any.The flexible principle of gas spring is：The triggering end of gas spring is pressed, when piston rod does not receive external force, its
The air pressure of therein can promote the piston rod of gas spring to stretch out；When piston rod is under pressure more than its own air pressure inside,
Piston rod will shrink.When stopping that triggering end is exerted a force, piston pole length is locked.
When needing to raise pedal, Height Adjustment button 1 is pressed, order about the bracing wire 3 that bracing wire is fixed on board component 2
Move, this displacement is led to that bracing wire fixture block 4 presses the triggering end of gas spring, now gas spring 5 unlocks function, gas spring
5 piston rod stretches out, and promotes connecting rod 8 to rotate counterclockwise, the lifting of guide pad 7 that drive is connected with Timing Belt 6, so that pedal liter
It is high.When pedal moves to required position, Height Adjustment button 1 i.e. lockable pedal is unclamped highly.
When needing to reduce pedal, Height Adjustment button 1 is pressed, order about the bracing wire 3 that bracing wire is fixed on board component 2
Move, this displacement is led to that bracing wire fixture block 4 presses the triggering end of gas spring 5, now gas spring 5 unlocks function, jams on pin
Pedal surface, guide pad 7 is moved downward, and moves downward movable pulley 9 by Timing Belt 6, pulls connecting rod to make gas spring
Piston rod shrinks, and when pedal height reduction position needed for, unclamps Height Adjustment button 1 i.e. lockable pedal highly.
