Through the distance of adjusting horizontal pole and rail, carry out the operation of anticreep rail, resume the back at train running state, withdraw from anticreep rail operating condition, effectively solved train anticreep rail problem and traditional anticreep rail device can not avoid the problem with orbital friction completely when the train normally traveles or turns. Meanwhile, one end of the cross rod, which is close to the rail, is set to be a curved surface, so that the abrasion to the rail is reduced.
Description
Technical Field
The utility model relates to a train derailment prevention device especially relates to a train operation derailment prevention device.
Background
The improvement of the economic standard of living of the vehicle-mounted, the running speed of the train is faster and faster, the harm brought by the derailment event of the train is heavier and heavier, and the derailment prevention device for the train running is urgently needed.
Patent CN102923154A discloses an anti-derailing device for train operation, which adopts the way that the upper end of an anti-derailing hook is buckled on a chassis girder of a train, and the lower end is buckled on a track and fastened by a fastening bolt. The scheme can not completely avoid the friction with the track when the train normally runs or turns, and the higher the running speed is, the greater the influence on the normal running of the train is.
Patent CN107953896B discloses an embrace rail type rail train anticreep rail device adopts the mode of outer lamella and interior lamella parcel in the track inboard and outboard, has effectively reduced the probability that the train operation derailed, nevertheless still exists the problem that can not avoid completely with orbital friction when normally traveling or turning.
Disclosure of Invention
The utility model provides a train operation anticreep rail device judges the running state of train through distance measuring sensor, when the controller judges that the train will derail, through the distance of adjusting horizontal pole and rail, 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 can not avoid completely with orbital frictional problem when the train normally traveles or turns.
The technical scheme of the utility model is that:
the utility model provides a train operation anticreep rail device, mainly includes wheel, rail, frame, sets up the range sensor of frame bottom directly over the rail, fixes the connecting plate on the frame, sets up in the wheel outside and fixes the anticreep rail subassembly in the connecting plate bottom.
The derailment prevention assembly comprises a hydraulic cylinder fixed on the connecting plate through a vertical connecting rod and a cross rod horizontally arranged on the hydraulic cylinder.
The cross rod and the curved surface at the bottom of the railhead are on the same horizontal plane, and the cross rod can move transversely under the operation of the hydraulic cylinder.
Specifically, one end, close to the curved surface of the bottom of the railhead, of the cross rod is a curved surface.
The distance measuring sensor is connected with the controller through a wire harness, and the controller can control the hydraulic cylinder to push the cross rod to move transversely through judging signals of the distance measuring sensor, so that the distance between the cross rod and the curved surface at the bottom of the railhead is adjusted.
Compared with the prior art, the utility model produced beneficial effect is:
(1) through the distance of adjusting horizontal pole and rail, can play the effect of anticreep rail.
(2) The running state of the train is detected through the distance measuring sensor, and the derailment prevention operation is only carried out when the controller judges that the train is about to derail, so that the problem that the conventional derailment prevention device cannot completely avoid friction with the track when the train normally runs or turns is solved.
(3) The end of the cross rod close to the rail is set to be a curved surface, so that the abrasion to the rail is reduced.
Description of the drawings:
FIG. 1 is a schematic structural view of a derailment prevention device for train operation;
FIG. 2 is a side view of a derailment prevention mounting location for a train;
fig. 3 is a schematic structural view of the derailment prevention device in an operating state.
In the figure: the track comprises a connecting plate 1, wheels 2, rails 3, a cross rod 4, a hydraulic cylinder 5, a connecting rod 6, a distance measuring sensor 7, a vehicle frame 8, a track head 301, a track bottom 302 and a track head bottom curved surface 303.
The specific implementation mode is as follows:
as shown in the attached drawings 1 and 2, the train operation derailment prevention device mainly comprises wheels 2, a train rail 3, a frame 8, a distance measuring sensor 7 arranged at the bottom of the frame 8 right above the train rail 3, a connecting plate 1 fixed on the frame 8, and a derailment prevention assembly arranged on the outer side of the wheels 2 and fixed at the bottom of the connecting plate 1.
The derailment prevention assembly comprises a hydraulic cylinder 5 fixed on the connecting plate 1 through a vertical connecting rod 6 and a cross rod 4 horizontally arranged on the hydraulic cylinder 5.
The cross rod 4 and the curved surface 303 at the bottom of the railhead are in the same horizontal plane, and the cross rod 4 can move transversely under the operation of the hydraulic cylinder 5.
The advantage is like this, when detecting one side train and will derail, the hydraulic cylinder 5 of homonymy promotes horizontal pole 4 to the curved surface 303 center removal in railhead bottom, then plays the effect of anticreep rail.
Specifically, one end of the cross rod 4, which is close to the curved surface 303 of the bottom of the railhead, is a curved surface.
This has the advantage that the rail 4, which is curved at one end, reduces wear on the rail 3.
The distance measuring sensor 7 is connected with a controller through a wire harness, the controller is not shown in the figure, and the controller can control the hydraulic cylinder 5 to push the cross rod 4 to move transversely through judging signals of the distance measuring sensor 7 to adjust the distance between the cross rod 4 and the rail head bottom curved surface 303.
As shown in fig. 3, in the working state of the derailing prevention device, the distance between the cross rod 4 and the curved surface 303 of the bottom of the railhead is reduced, so that the derailing prevention function is achieved.
The working principle of the utility model is that when the distance measuring sensor 7 detects that the distance between the frame 8 and the rail 3 is increased, the distance between the control cross rod 4 and the rail head bottom curved surface 303 is reduced, thereby playing the role of derailment prevention; when the distance measuring sensor 7 detects that the distance between the frame 8 and the rail 3 returns to the initial value, the distance between the control cross rod 4 and the rail head bottom curved surface 303 is increased, and the problem that the friction between the control cross rod 4 and the rail cannot be completely avoided when the train normally runs or turns is avoided.
The above-described embodiments are merely illustrative of several embodiments of the present invention, which are described in more detail and detail, but are not to be construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
