Description
Technical field
The present invention relates to a kind of internal combustion engine reconnection test platform and method of work thereof.
Background technology
When locomotive is advanced in the big highway section of the gradient, adopt the separate unit diesel locomotive to be difficult to satisfy the requirement of heavy duty traction, often adopt two-shipper or multi locomotive traction to carry out locomotive double heading control.So-called locomotive double heading control just is meant that the driver operates two or many locomotives simultaneously on a locomotive, realizes the synchro control of two or many locomotives.When locomotive adopted two-shipper or multi locomotive traction, the braking of multi-locomotive, mitigation and train locomotive were harmonious fully, and by steward's brake activation machine of train locomotive, assisting vehicle the steward do not handle locomotive brake gear.
Brake is housed on the locomotive, and the driver is slowed down locomotive by the manipulation to brake or is stopped.The existing locomotive of China all adopts the automatic air brake machine, and wherein JZ-7 type brake is most widely used general.JZ-7 type brake comprises: Pneumatic brake systems and in order to produce and air compressor and total reservoir of pressure store air.
Pneumatic brake systems comprises:
(1) automatic brake valve (abbreviation): in order to braking and the alleviation of handling full train from valve.Automatic brake valve is automatic protective voltage type, seven active positions is arranged promptly: overcharge position, driving position, minimum decompression position (service application zone), maximum decompression position, over reduction position, handgrip fetch bit, emergency position.
(2) relay valve: according to automatic brake valve handle in all pipe pressure change, directly control the inflation or the exhaust of train pipe, thereby make train alleviation, braking or pressurize.
(3) distribution valve: change according to train tube pressure, the inflation of control action reservoir or exhaust, thus make the application valve action.
(4) application valve: according to the manipulation of variation of application reservoir pressure or independent brake valve, the inflation or the exhaust of control locomotive checking cylinder, thus make locomotive brake, pressurize or alleviation.
(5) independent brake valve (abbreviation single valve): in order to the braking or the alleviation of individual operation locomotive itself.Independent brake valve is provided with three handgrip positions, that is: independent release position, driving position, full application of brake position.
Also be provided with equalizing reservoir in addition, overcharge reservoir, parts such as work reservoir, step-down reservoir, emergency reservoir, application reservoir and makeshift valve, strainer check valve, emergency brake, pipe cleaner and various plug door, oil-water separator, crosspointer tensimeter, in order to finish the various not same-actions of brake.
The control relation of each valve wherein:
1. automatic brake valve → equalizing reservoir → relay valve → train pipe air pressure variations → locomotive distributing valve → application valve → checking cylinder.
2. independent brake valve → application valve → checking cylinder.
Multi-locomotive comprises double-heading valve, and its effect is when locomotive two-shipper or multi locomotive traction, and the release of brake effect and the train locomotive of multi-locomotive are harmonious fully, and by steward's brake activation machine of train locomotive, assisting vehicle the steward do not handle locomotive brake gear.But when train locomotive and multi-locomotive disconnected hook takes place separated, double-heading valve can make the checking cylinder of multi-locomotive accept the control of place locomotive distributing valve and independent brake valve, and makes train locomotive and multi-locomotive all be in on-position, played the protective effect after the separation.
When two-shipper or multi locomotive traction, train locomotive changes switching button in the train locomotive position, multi-locomotive changes switching button in the multi-locomotive position, the automatic brake valve of train locomotive and independent brake valve handle all place driving position, the automatic brake valve handle of multi-locomotive places the handle fetch bit, and the independent brake valve handle places driving position.When train locomotive carries out train braking, because train pipe decompression, the distribution valve effect pipe of train locomotive produces pressure air, but the pressure air of multi-locomotive flows into the groove of double-heading valve piston bar can not be flowed into application valve by blocking effect pipe, thereby the brake-cylinder pressure of multi-locomotive just is not subjected to the control of its distribution valve.And the pressure air of the distribution valve effect pipe of train locomotive flows into the effect pipe of application valve through double-heading valve piston bar groove, application valve is had an effect, thereby make total reservoir pressure air flow into checking cylinder and through the effect pipe of the average tube → multi-locomotive of the double-heading valve of the average tube → multi-locomotive of the average tube → multi-locomotive of the average tube → train locomotive of the braking earthen pipe → double-heading valve of the intercepter valve (IV) of train locomotive double-heading valve through application valve, thereby make the application valve action of multi-locomotive, produce braking action.
If two-shipper or multi locomotive traction, train locomotive is handled the braking of train locomotive with independent brake valve or when alleviating, situation is identical when handling with automatic brake valve, difference is that the pressure air of the pipeline of double-heading valve is not next by the effect pipe of distribution valve, but come by independent brake valve action pipe.Identical when the braking action of train locomotive and multi-locomotive is handled with automatic brake valve, the effect of multi-locomotive application valve is still controlled by the pressure air that the train locomotive average tube is come.
When two-shipper or multiple-operated locomotive units, after the Braking mode effect takes place, when needing the braking of independent release locomotive, also must be handled by the steward of train locomotive, the braking that the multi-locomotive steward can not the spontaneous remission locomotive removes the switching button of non-conversion double-heading valve.After two-shipper or multi locomotive traction carry out braking action, when train locomotive is wanted the independent release locomotive brake, the train locomotive steward must push the independent brake valve handle to the independent release position, this moment, the work reservoir pressure of train locomotive distribution valve descended, distribution valve main valve 22 is alleviated, the pressure air row of distribution valve effect pipe is to atmosphere, owing to communicate with the effect pipe of application valve, the pressure of event also descends, the application valve effect of train locomotive, make brake-cylinder pressure enter atmosphere through the application valve exhausr port, make train locomotive generation mitigation, because brake-cylinder pressure descends, the average tube pressure of train locomotive also descends, thereby the pressure of multi-locomotive average tube is also descended, and the average tube of multi-locomotive is to communicate with the effect pipe of its application valve through double-heading valve, thus pressure also descend, the application valve of multi-locomotive is also had an effect, make the pressure of multi-locomotive checking cylinder enter atmosphere, thereby alleviated the braking of multi-locomotive through the exhausr port of multi-locomotive application valve.
When two-shipper or multi locomotive traction, when the hook locomotive that takes place for a certain reason to break separates, the rapid air draft of train pipe, braking action all takes place in train locomotive and multi-locomotive, but all ruptures because of always wind signal pipe and average tube again simultaneously, and double-heading valve is just had an effect, at first make the blocking of checking cylinder intercepter valve (IV), the pressure air that prevents checking cylinder flows into average tube through the braking earthen pipe, makes train locomotive can not enter atmosphere through the brake-cylinder pressure that application valve produced, and has guaranteed the safety of train locomotive.The double-heading valve of multi-locomotive is had an effect simultaneously, make it automatically to change over to the train locomotive position, this moment, the pressure of the effect pipe that the multi-locomotive distribution valve is produced just can not interdicted in double-heading valve, but flow into the effect pipe of application valve through the groove of double-heading valve piston bar, make the application valve action and produce braking action, also cut off simultaneously and being communicated with of average tube, thereby guaranteed the braking action of multi-locomotive after the locomotive separation.
The diesel locomotive of above-mentioned existing multi locomotive traction must carry out two-shipper and heavily join standing test in producing and repairing process, to guarantee the safety of actual use.In the prior art, the locomotive double heading standing test must be carried out simultaneously by two locomotives, finishes pilot project jointly.And the situation that the short-term unit is built in factory often appears in actual production process, in the case, the locomotive double heading standing test just can't be carried out, car can only be handed in advance by maintenance depot, to Duan Houzai and the additional standing test that heavily joins of other locomotives, so influenced the efficient that locomotive is produced and repaired in locomotive greatly.
