Disclosure of Invention
The utility model provides a track train anticreep rail device judges the running state of train through distance sensor, when the controller judges that the train will derail, through adjusting permanent magnet and orbital distance, carries out the operation of anticreep rail, resumes the back at train running state, moves out anticreep rail operating condition, has effectively solved train anticreep rail problem and traditional anticreep rail device and has had the problem of can not avoid completely with orbital friction when normally traveling or turning. Simultaneously, distance measurement through different positions is carried out, and derailment prevention operation is carried out only when the controller simultaneously receives derailment signals of the two distance sensor trains, so that the accuracy of state judgment of the controller can be greatly increased, and misoperation of the controller is prevented.
The technical scheme of the invention is as follows: the utility model provides a track train anticreep rail device, mainly includes bottom plate, train wheel, sets up first distance sensor, second distance sensor and the anticreep rail subassembly of bottom plate below between two train wheels.
The derailment prevention assembly comprises a first working cylinder and a second working cylinder which are fixedly arranged below the bottom plate, and permanent magnets which are hung through a first operating rod and a second operating rod respectively, and the first working cylinder and the second working cylinder can control the distance between the permanent magnets and the track through the first operating rod and the second operating rod respectively.
The first distance sensor and the second distance sensor are arranged on two sides of the permanent magnet.
Specifically, the first distance sensor and the second distance sensor are both connected with the controller through a wire harness, the controller is not shown in the figure, and the controller can control the first working cylinder and the second working cylinder to respectively push the first operating rod and the second operating rod to move downwards through judging signals of the distance sensors.
More specifically, when the controller receives train derailing signals of the first distance sensor and the second distance sensor at the same time, the controller operates the working cylinder correspondingly.
Under derailing prevention device operating condition, the permanent magnet adsorbs on the track, can prevent the train derail. Compared with the prior art, the utility model produced beneficial effect is:
(1) the controller adjusts the distance between the permanent magnet and the track by controlling the working cylinder and the operating rod, and when the permanent magnet is adsorbed to the track, the train can be prevented from derailing.
(2) When the controller judges that the train normally runs, the working state of derailment prevention is withdrawn, so that the problem that the traditional derailment prevention device cannot completely avoid friction with the track when the train normally runs or turns is solved.
(3) Through the distance measurement of different positions, and only when the controller received two distance sensor train derailment signals simultaneously, carry out the operation of derailing again, accuracy that can greatly increased controller state judgement prevents the controller maloperation.
Description of the drawings:
FIG. 1 is a schematic structural view of a derailment prevention device of a rail train;
fig. 2 is an operation schematic diagram of a derailment prevention device of a rail train.
In the figure: 1-bottom plate, 2-first distance sensor, 3-first working cylinder, 4-first operating rod, 5-second working cylinder, 6-second operating rod, 7-second distance sensor, 8-train wheel, 9-permanent magnet and 10-track.
The specific implementation mode is as follows:
as shown in fig. 1, the derailing prevention device for the railway train mainly comprises a bottom plate 1, train wheels 8, a first distance sensor 2 arranged below the bottom plate 1 between the two train wheels 8, a second distance sensor 7 and a derailing prevention assembly.
Derailment prevention subassembly is including fixed first working cylinder 3 and the second working cylinder 5 that sets up in bottom plate 1 below to and hang the permanent magnet 9 that sets up through first action bars 4, second action bars 6 respectively, and first working cylinder 3 and second working cylinder 5 can be respectively through first action bars 4, the distance of second action bars 6 control permanent magnet 9 apart from track 10.
This has the advantage that the train can be prevented from derailing when the permanent magnets 9 are attracted to the rail 10.
The first distance sensor 2 and the second distance sensor 7 are arranged on two sides of the permanent magnet 9.
The advantage of this is that the accuracy of the distance detection can be greatly increased by the distance measurement at different positions.
Specifically, the first distance sensor 2 and the second distance sensor 7 are both connected to a controller through a wire harness, the controller is not shown in the figure, and the controller can control the first working cylinder 3 and the second working cylinder 5 to respectively push the first operating rod 4 and the second operating rod 6 to move downwards through judging signals of the distance sensors.
More specifically, when the controller receives train derailment signals of the first distance sensor 2 and the second distance sensor 7 at the same time, the controller operates the working cylinder correspondingly.
The advantage is that only when the controller received two distance sensor train derailment signals simultaneously, carries out the derailment operation again, is carrying out the judgement of whether the train derailed the state, and the accuracy that can greatly increased state judgement prevents the maloperation.
As shown in fig. 2, in the working state of the derailing prevention device, the permanent magnet 9 is adsorbed on the rail 10, so that the derailing of the train can be prevented.
The advantage is so, when the controller judges train normal operating, withdraw the derailment prevention operating condition, has avoided traditional derailment prevention device can not avoid completely with orbital friction's problem when the train normally travels or turns.
The utility model discloses an operating principle does, when first distance sensor 2 and second distance sensor 5 all detected bottom plate 1 apart from track 10's distance grow, first working cylinder 3 of controller control, second working cylinder 5 promote first action bars 4, 6 downstream of second action bars respectively for permanent magnet 9 prevents the train derail on adsorbing track 10. When the first distance sensor 2 and the second distance sensor 7 both detect that the distance from the bottom plate 1 to the rail 10 returns to the initial value, the controller controls the first working cylinder 3 and the second working cylinder 5 to respectively push the first operating rod 4 and the second operating rod 6 to move upwards, so that the permanent magnet 9 is far away from the rail 10, and the attraction of the permanent magnet 9 to the rail 10 is released.
