Background technology
Train wheel in running with rail rolling friction, bend, braking, on circuit the impact of other foreign body etc. because of
Element, is running after certain mileage, and wheel surface exists abrasion, needs to use lathe used for machining in-situ locomotive wheel that wheel surface carries out Xuan and repaiies and turn over
New reparation.Train is in running simultaneously, because being mingled with in wheel material, the medium factor of stress collection, in inside wheel meeting
Produce fatigue failure, need to use ultrasonic examination technology that inside wheel is detected a flaw.
Before using ultrasonic fault detection system that Railway wheelset is detected a flaw, hydraulic system drive the lifting body controlled
Extending arm ride on rail and by wheel being in jacking state.But, if stopping suddenly when wheel is to the state being in by jacking
Electricity, equipment cannot unload, and wheel is to lowering, and train cannot outbound operation.
Therefore, how solving in prior art, if having a power failure suddenly, being in the wheel of jacking state to asking of cannot unloading down
Topic, becomes those skilled in the art's important technological problems to be solved.
Summary of the invention
In view of this, it is an object of the invention to provide a kind of railway train wheel standby discharge mechanism to fault detection system,
It can will be in the wheel of jacking state to unloading in the case of having a power failure suddenly.
A kind of railway train wheel that the present invention the provides standby discharge mechanism to fault detection system, drives including by hydraulic system
Dynamic lifting body be connected with described hydraulic system by the first fluid pressure line, using the power source as described hydraulic system
Main oil pump, also include being connected with described hydraulic system by the second fluid pressure line, standby using as described hydraulic system
The hand oil pump of power source, when described main oil pump stops, hand oil pump described in manual operation can provide to described hydraulic system
Driving source.
Preferably, the first fluid pressure line is provided with the first check valve, when described main oil pump is to described hydraulic system fuel feeding,
Described first check valve conducting.
Preferably, described second fluid pressure line is provided with the second check valve, when described hand oil pump supplies to described hydraulic system
During oil, described second check valve conducting.
Preferably, described second fluid pressure line is connected with described first fluid pressure line, and link position is positioned at described
The downstream of one check valve.
Preferably, described hand oil pump port with described second fluid pressure line pluggablely is connected.
In the technical scheme that the present invention provides, when working properly, main oil pump, as the power source of hydraulic system, is used for driving
Move the jacking of lifting body and pack up, Railway wheelset jacking is got up or unloads.When having a power failure suddenly, if Railway wheelset
It is in by the state of jacking, due to main oil pump cisco unity malfunction, now, the hand oil pump that the present invention provides can be used, operation
Human users's hand oil pump provides power to hydraulic system, and then lifting body can be made to fall, so that being in jacking state
Railway wheelset unloads.Being arranged such, the standby discharge mechanism that the present invention provides, even if also can will be in jacking after Ting electricity ing
The wheel of state is to unloading.
Accompanying drawing explanation
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
In having technology to describe, the required accompanying drawing used is briefly described, it should be apparent that, the accompanying drawing in describing below is only this
Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to
Other accompanying drawing is obtained according to these accompanying drawings.
Fig. 1 is the schematic diagram of hydraulic system in the specific embodiment of the invention.
In Fig. 1:
Main oil pump-11, the first fluid pressure line-12, the second fluid pressure line-13, hand oil pump-14, the first check valve-15,
Second check valve-16.
Detailed description of the invention
The railway train wheel that this detailed description of the invention the provides standby discharge mechanism to fault detection system, it can stop suddenly
In the case of electricity, the wheel of jacking state will be in unloading.
Hereinafter, referring to the drawings embodiment is illustrated.Additionally, embodiments illustrated below is not to described in claim
Summary of the invention play any restriction effect.It addition, the full content of the composition represented by example below is not limited to as right
Necessary to the solution of the invention described in requirement.
Refer to Fig. 1, a kind of railway train wheel that this detailed description of the invention the provides standby discharge mechanism to fault detection system,
Including the lifting body driven by hydraulic system be connected with hydraulic system by the first fluid pressure line 12, using as hydraulic pressure
The main oil pump 11 of the power source of system.
It should be noted that the main oil pump 11 that this detailed description of the invention provides is by driven by power, Railway wheelset fault detection system
In course of normal operation, by main oil pump 11 as power source, pressure oil is supplied hydraulic system, to drive lifting body that wheel is right
Jack-up or put down, when having a power failure, main oil pump 11 runs out of steam and quits work, and lifting body keeps the most motionless, so, if take turns right
It is in by jacking state, then can not unload.
In consideration of it, the standby discharge mechanism that this detailed description of the invention provides, also include by the second fluid pressure line 13 and liquid
Pressure system is connected, using the hand oil pump 14 of the back-up power source as hydraulic system, when main oil pump 11 stops, manual operation
Hand oil pump 14 can provide driving source to hydraulic system.
When having a power failure suddenly, if Railway wheelset is in by the state of jacking, due to main oil pump 11 cisco unity malfunction, this
Time, the hand oil pump 14 that this detailed description of the invention provides can be used, operator operate hand oil pump 14 and provide to hydraulic system
Power, and then lifting body can be made to fall, so that the Railway wheelset being in jacking state unloads.It is arranged such, this
The standby discharge mechanism of bright offer, even if also can will be in the wheel of jacking state to unloading after Ting electricity ing.
In the preferred version of this detailed description of the invention, the first fluid pressure line 12 is provided with the first check valve 15, works as main oil pump
11 when hydraulic system fuel feeding, and the first check valve 15 turns on, otherwise then ends.It is arranged such, it is possible to avoid hydraulic oil reverse flow
Dynamic.
Equally, the second fluid pressure line 13 can be provided with the second check valve 16, when hand oil pump 14 is to hydraulic system fuel feeding,
Second check valve 16 turns on, otherwise then ends.
Further, the second fluid pressure line 13 is connected with the first fluid pressure line 12, and link position to be positioned at first unidirectional
The downstream of valve 15.Being arranged such, when hand oil pump 14 works, hydraulic oil will not enter in main oil pump 11, main oil pump 11 work
When making, hydraulic oil also will not enter in hand oil pump 14, it is to avoid influencing each other of main oil pump 11 and hand oil pump 14.
It addition, in this detailed description of the invention, hand oil pump 14 port with the second fluid pressure line 13 pluggablely is connected,
When need not hand oil pump 14, hand oil pump 14 can be pulled up, the most again hand oil pump 14 being inserted to the second hydraulic tube
On road 13.
Described above to the disclosed embodiments, makes professional and technical personnel in the field be capable of or uses the present invention.
Multiple amendment to these embodiments will be apparent from for those skilled in the art, as defined herein
General Principle can realize without departing from the spirit or scope of the present invention in other embodiments.Therefore, the present invention
