Description
Technical field
The present invention relates to a kind of track taking-up vehicle crossbeam control technology field, more particularly, to a kind of track taking-up vehicle crossbeam overload alarm
System and control method.
Background technology
, it is necessary to which being equipped with track taking-up vehicle carries out transporting precast beams or rail receipts during bridge erection, construction of railways, maintenance etc.
Work is unloaded, and supports the use the transport that flatcar realizes precast beam or rail.
Track taking-up vehicle has a variety of, and the track taking-up vehicle vehicle that uses of work business system is essentially LSD-1 types at present, and it receives rail device crossbeam
It is removable.Crossbeam, per side away from the mm of wire center 1613, meets in middle position《Regulations of railway technical operation-general speed》" locomotive
Gauge " requires；When receipts unload rail, crossbeam is removed, after receipts unload rail, then after crossbeam is moved back into middle position, railcar continues
Operation, greatly facilitate scene and receive rail operation, saved receipts and unloaded the rail activity duration, improved operating efficiency.But work progress
In it is all very nervous, if finding not in time, after crossbeam removal, remove side crossbeam outermost end away from wire center 2153mm, with
《Regulations of railway technical operation-general speed》" mixed passenger and freight railway vehicle gauge of the locomotive " 1700mm as defined in accompanying drawing 2, which is compared, to be exceeded
453mm, such LSD-1 types receipts rail device is in use, there is very big security risk：
1. receiving the crossbeam for unloading and being removed during rail operation, may not received after operation because of the carelessness of operating personnel
Return, railcar continues to run；After 2. receipts unload rail operation, although withdrawing crossbeam, wanted because operating personnel does not press
Locking crossbeam or locking device failure are asked, causing vehicle, crossbeam removes in the process of running；3. vehicle is when driving, due to
Jolting causes locking mechanical lock to be jumped out.
If can not find and be handled in time, track taking-up vehicle, railcar will be caused because crossbeam collision is transfinited or faced
The generation of the major accidents such as the breakage of alignment car, off-line, rollover or the other travelling facilities of damage.This just needs to research and develop a set of track taking-up vehicle
Crossbeam overrun alarm system.
By investigation, the research of track taking-up vehicle crossbeam overload alarm is also seldom at present, and majority is single to rest on cross beam lock
In fixed detection.If crossbeam does not lock, equipment is then handled accordingly.And the detection of crossbeam locking can not be automatic
Change, most cases need to adjust detection device, to reach testing goal.Not only efficiency is low for this detection means, adds simultaneously
Many human factors and uncertain factor.In terms of restriction and alarm to crossbeam position, the country is almost not involved with crossbeam
Position signalling is transferred to railcar, can not realize that can detects track taking-up vehicle crossbeam state in railcar.When driving,
The position of crossbeam can not be even more detected, being transfinited for crossbeam during driving does not reach the effect of alarm
Communication majority uses wire communication, this kind of communication modes, in dismounting receipts rail on other track taking-up vehicle at present and railcar
It is abnormal numerous and diverse when car and railcar.
The content of the invention
Track taking-up vehicle crossbeam transfinites and can caused a serious accident in the prior art for the present invention mainly solution, and current track taking-up vehicle
Overload alarm imperfection, the problem of alarm function can not be played, there is provided a kind of alarm structure is perfect, realize can in railcar
Detect the track taking-up vehicle crossbeam overrun alarm system of crossbeam state.
Present invention also offers a kind of track taking-up vehicle crossbeam overload alarm control method.

Connect, the railcar part includes the railcar wireless transmit/receive units of speed detection unit and track taking-up vehicle section communication, according to horizontal stroke
The alarm unit whether beam-like state and velocity estimated alarm, speed detection unit and railcar wireless transmit/receive units respectively with report
Alert device unit connection.Present system can detect to track taking-up vehicle crossbeam position, detect that the non-return of crossbeam, return are unlocked
Fixed or locking failure situation, railcar are alarmed, and are reminded railcar driver to be unable to motor-car or stop immediately, are efficiently solved receipts
The non-return of rail car crossbeam or it is unlocked caused by transfinite the security risk problem of driving, avoid because transfinite crossbeam collision and caused by
Track taking-up vehicle, railcar or face the breakage of alignment car, off-line, rollover or the generation for damaging the major accidents such as other travelling facilities, greatly
The big probability reduced to the interference of railways train operation order.Speed detection unit uses GYK devices, and GYK devices pass through public data
Case output speed information is to alarm unit.
As a kind of preferred scheme, the limit switch sensor unit include detection crossbeam one end whether return and lock
The first fixed return detection sensor and the first lock-in detection sensor, the detection crossbeam other end whether the second of return and locking
Return detection sensor and the second lock-in detection sensor, the first return detection sensor, the first lock-in detection sensor, second
Return detection sensor and the second lock-in detection sensor are connected with main computer unit respectively.The detection of first return detection sensor is horizontal
Beam one end whether return, whether the first lock-in detection sensor detection crossbeam one end is locked, and the second return detection sensor is examined
Survey the crossbeam other end whether return, whether the second lock-in detection sensor detection crossbeam other end lock.These sensors will be examined
The signal measured is sent to main computer unit.
As a kind of preferred scheme, the main computer unit includes host control panel, main frame first crossbeam return indicator lamp, master

Close sensor unit status information；
S3. whether detection limit switch sensor unit there is non-return or unlocked signal, continues to detect if not, if
Into lower step；
S4. detect whether track vehicle speed is zero, if then showing crossbeam state, return to step S3, if otherwise starting sound
Light alarm simultaneously shows crossbeam state；
S5. detect whether track vehicle speed is zero, if otherwise continuing alarm and repeat step S5, if then releasing alarm.
Control method of the present invention detects to track taking-up vehicle crossbeam position, is detecting that the non-return of crossbeam, return are unlocked
Or locking failure situation, railcar are alarmed, and are reminded railcar driver to be unable to motor-car or stop immediately, are efficiently solved receipts rail
The non-return of car crossbeam or the security risk problem of unlocked caused driving of transfiniting.
As a kind of preferred scheme, the detecting step to alarm release button, step are also included before the step S5
Include detecting whether to press alarm release button, be zero in track vehicle speed if then releasing alarm if not into step S5
Afterwards, alarm release state is refreshed.Increase the step of manual operation releases alarm.
Therefore, it is an advantage of the invention that：Alarmed 1. can be transfinited to track taking-up vehicle crossbeam, efficiently solve track taking-up vehicle crossbeam
Non- return or it is unlocked caused by transfinite the security risk problem of driving, avoid because transfinite crossbeam collision and caused by receive rail
Car, railcar face the breakage of alignment car, off-line, rollover or the generation for damaging the major accidents such as other travelling facilities, substantially reduce
To the probability of railways train operation order interference.2. realizing track taking-up vehicle crossbeam state is detected in railcar can.3. use nothing
Line communication modes, it is more convenient when dismounting track taking-up vehicle and railcar.
