Abstract
Inspection method is snapped at goods train brake beam arcuate rod end cephalic slit line, roller, it is related to rolling stock trouble shooting technical field；It is comprised the following steps：See brake shoe and tread contact site whether deflection, inner side gapless, outside has gap abnormal, to confirm whether arcuate bar fractures, holds whether axle snaps in detail；See whether the angle iron that brake beam compression channel welds with arcuate boom end snaps；Whether have the iron powder or bright line that appear, and confirm whether roller outwardly or inwardly scurries out if seeing the weld of roller and brake head；Whether whether the channel-section steel of brake beam deform, stretch or carry on the back inwards in terms of delthyrium；If whether brake shoe is too small, too small from a distance from rail from the appearance to carry out emphasis inspection to end axle of brake beam, sees whether end axle fractures or wear away and whether exaggerate.The present invention is easy to exclude due to snapping caused locomotive failure at brake beam arcuate rod end cephalic slit line, roller, improves overhaul efficiency, has ensured the property and life safety of people.
Description
Technical field
The present invention relates to rolling stock trouble shooting technical field, and in particular to goods train brake beam arcuate rod end cephalic slit
Inspection method is snapped at line, roller.
Background technology
With China's expanding economy, China railways also obtain larger development, take turns the most critical to being run as vehicle
Link, weight bearing power and the speed of service for vehicle suffer from very important influence, therefore are also that passenger train exists
One of Test Gauge project in running.In the event of wheelset failure, not in time handle, it will trigger vehicle
The security incident of operation, it is serious that huge loss is brought to railway transportation phenomena such as also vehicle will being caused to overturn, derail,
Property and life to people cause safely huge threat.
Brake apparatus is the important component of railway freight-car, is the important leverage of Railway Freight Transportation order and security.
Railway vehicle braking device mainly includes brake rigging and air brake, and common brake apparatus is to pass through on vehicle
The change of air pressure in train supervisor and brake apparatus is produced corresponding action, the common brake apparatus in lorry utilization
Failure includes：Brake beam failure, air damper failure and band-type brake failure.
Vehicle is run on uneven circuit and the defect of wheel tread, snaps position vibration；Individual vehicle
Braking leverage is small, and brake shoe is low with the bonding rate of wheel tread, roller is beated back and forth between upper lower wing plate, easily causes arcuate
The contact position of bar and brake head is snapped and roller snaps, scurried out.
The content of the invention
In view of the defects and deficiencies of the prior art, the present invention intends to provide one kind is easy to exclude because brake beam bends
Opened at the goods train brake beam arcuate rod end cephalic slit line of locomotive failure caused by being snapped at type rod end cephalic slit line, roller, roller
Weld inspection method.
To achieve the above object, the technical solution adopted by the present invention is：Goods train brake beam arcuate rod end cephalic slit line, rolling
Inspection method is snapped at rod, it is comprised the following steps：
1st, see brake shoe and tread contact site whether deflection, inner side gapless, outside has gap abnormal, to confirm to bend in detail
Whether type bar fractures, holds whether axle snaps；
2nd, see whether the angle iron that brake beam compression channel welds with arcuate boom end snaps；
Whether have the iron powder or bright line that appear, and confirm whether roller outwardly or inwardly alters if the 3, seeing the weld of roller and brake head
Go out；
4th, whether the channel-section steel of brake beam deform, stretch or carry on the back inwards in terms of delthyrium, differentiates whether arcuate bar fractures with this；
If the 5, whether brake shoe is too small, too small from a distance from rail from the appearance to carry out emphasis inspection to end axle of brake beam, see
Whether whether end axle fractures or wear away is exaggerated.
After the above method, had the beneficial effect that caused by the present invention：Goods train brake beam arcuate of the present invention
Inspection method is snapped at rod end cephalic slit line, roller, is easy to exclude to cause due to snapping at brake beam arcuate rod end cephalic slit line, roller
Locomotive failure, improve overhaul efficiency, ensured people property and life safety.
Embodiment
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to above-mentioned technical side
Case is described in detail.
Present embodiment adopts the following technical scheme that：Opened at goods train brake beam arcuate rod end cephalic slit line, roller
Inspection method is welded, it is comprised the following steps：
1st, see brake shoe and tread contact site whether deflection, inner side gapless, outside has gap abnormal, to confirm to bend in detail
Whether type bar fractures, holds whether axle snaps；
2nd, see whether the angle iron that brake beam compression channel welds with arcuate boom end snaps；
Whether have the iron powder or bright line that appear, and confirm whether roller outwardly or inwardly alters if the 3, seeing the weld of roller and brake head
Go out；
4th, whether the channel-section steel of brake beam deform, stretch or carry on the back inwards in terms of delthyrium, differentiates whether arcuate bar fractures with this；
If the 5, whether brake shoe is too small, too small from a distance from rail from the appearance to carry out emphasis inspection to end axle of brake beam, see
Whether whether end axle fractures or wear away is exaggerated.
After the above method, had the beneficial effect that caused by present embodiment：Iron described in present embodiment
Inspection method is snapped at road van brake beam arcuate rod end cephalic slit line, roller, is easy to exclude due to brake beam arcuate rod end cephalic slit
Caused locomotive failure is snapped at line, roller, improves overhaul efficiency, has ensured the property and life safety of people.
The general principle and principal character and present embodiment of present embodiment has been shown and described above
The advantages of.It should be understood by those skilled in the art that present embodiment is not restricted to the described embodiments, above-described embodiment
The principle for simply illustrating present embodiment with described in specification, is not departing from present embodiment spirit and scope
On the premise of, present embodiment also has various changes and modifications, and these changes and improvements both fall within claimed sheet
In the range of embodiment.Scope is claimed by appended claims and its equivalent circle in present embodiment
It is fixed.
Claims (1)
1. snap inspection method at goods train brake beam arcuate rod end cephalic slit line, roller, it is characterised in that it includes following step
Suddenly：
(1), see brake shoe and tread contact site whether deflection, inner side gapless, outside has gap abnormal, confirmed in detail
Whether arcuate bar fractures, holds whether axle snaps；
(2), see whether the angle iron that brake beam compression channel welds with arcuate boom end snaps；
(3) outwardly or inwardly whether, seeing the weld of roller and brake head has the iron powder or bright line appeared, and confirm roller
Scurry out；
(4), whether the channel-section steel of brake beam deform, stretch or carry on the back inwards in terms of delthyrium, differentiates whether arcuate bar is rolled over this
It is disconnected；
(5) if, from the appearance brake shoe whether from a distance from rail it is too small, too small will to end axle of brake beam carry out emphasis inspection,
See whether end axle fractures or wear away whether to exaggerate.
