Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of warning devices, in particular to a landmark warning device for a train station platform. BACKGROUND

[0002] A train station platform, in full a high-speed railway train station platform, is a train station that cooperates with the normal operation of a high-speed railway system. A row of warning safety lines is engraved near the rail on each train station platform, and some are installed on isolation poles in some areas to prevent accidents. The warning safety lines engraved near the rail and the isolation poles can be called a landmark warning device for a train station platform.

[0003] However, the existing warning device has a large gap between the front and rear carriages of the train and the platform, and passengers will inevitably be crowded when getting on and off the train, which will fall between the train and the platform, posing a huge safety hazard. Currently, warning tapes are mainly used to remind passengers to be safety-aware. The main body of the warning tape is in the form of a strip, with magnets at both ends. When the train arrives at the station, the crew will fix the warning tape by attracting the front and rear carriages with the magnets, and remove it before departure. Such a warning tape can only serve as a warning and cannot solve the safety problem. Moreover, the crew needs to hold the step with one hand and the warning tape with the other hand when the train is at the station, which is a cumbersome operation. Patent No. CN218141555U, entitled "Train safety warning tape", uses two sets of safety belts with self-locking function, which is similar to the principle of car safety belts. When subjected to a sudden force impact, it immediately locks, effectively preventing passengers from falling between the train and the platform, ensuring the safety of customers, thereby solving the above problems.

[0004] However, when using the landmark warning device for a train station platform, the warning safety line can only serve as a warning, and its effectiveness depends on people's self-consciousness. When someone crosses the warning safety line, there is no warning device, so the surrounding staff cannot discover it in time, which poses a safety hazard. The isolation pole for isolating personnel is only installed in some areas and cannot completely separate the track from the personnel, so its range of action is small. Therefore, it does not meet the existing needs, and thus we propose a landmark warning device for a train station platform. SUMMARY

[0005] The landmark warning device for the platform of the train station provided by the present application can solve the problems of the prior art, such as the fact that the warning safety line can only play a warning role, the effect depends on the self-consciousness of people, and when someone crosses the warning safety line, the surrounding staff cannot discover it in time due to the lack of a warning device, thereby causing a hidden danger, and the fact that the isolation rod for isolating personnel is only installed in a part of the area and cannot completely isolate the track from the personnel, and the fact that the range of action is small.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments.

[0030] Please refer to Figures 1 to 6 An embodiment provided by the present application is a landmark warning device for a train station platform, which comprises a stone platform 1, a concave metal plate 10 fixed on one side of the upper end surface of the stone platform 1, a strip-shaped storage groove 3 provided on one side of the upper end surface of the concave metal plate 10, a partition plate 4 provided in the strip-shaped storage groove 3, a warning line 5 provided behind the partition plate 4, a plurality of storage grooves 7 provided on the upper end surface of the warning line 5, a lifting column 6 provided in each storage groove 7, an alarm lamp 8 fixedly installed on the upper end surface of the middle position of the lifting column 6, and a plurality of laser sensors 9 fixedly installed on both sides of the outer surface of the lifting column 6. In use, the use of each mechanism is checked, the device is moved to the working area and connected to the power supply, the laser emitted by the laser sensor 9 is on the same parallel line as the warning line 5, and when someone crosses the warning line 5, the laser emitted by the laser sensor 9 will be touched, so that the alarm lamp 8 is automatically started and gives a warning to prompt the staff to come in time to handle, thereby increasing the safety of the equipment.

[0031] The middle position of the front end face of the stone table top 1 is provided with a triangular drainage groove 13, and the inner wall of the lower end of the strip-shaped storage groove 3 is provided with a plurality of drainage ports 12 extending to the inner wall of the upper end of the triangular drainage groove 13 through the concave metal plate 10 and the stone table top 1. In rainy weather, if water enters the interior of the storage groove 7 or the strip-shaped storage groove 3, the water entering the interior of the storage groove 7 will drip through the storage groove 7 to the inclined surface of the triangular drainage groove 13, and the water entering the interior of the strip-shaped storage groove 3 will drip through the drainage port 12 on the inner wall of the lower end of the strip-shaped storage groove 3 to the inclined surface of the triangular drainage groove 13, and will be discharged through the inclined surface.

[0032] The lower end surface of the plurality of lifting columns 6 is connected with an automatic locking type lifting cleaning mechanism 2. The automatic locking type lifting cleaning mechanism 2 comprises an upper inclined surface type metal base 222. The interior of the upper inclined surface type metal base 222 is provided with a plurality of transmission shafts 204, the number of which is the same as that of the lifting columns 6 and the positions of which correspond to those of the lifting columns 6. The lower side of the outer surface of each transmission shaft 204 is fixedly provided with a synchronous sprocket 205. All the synchronous sprockets 205 are connected in series through a synchronous chain A 206.

[0033] The rear of the transmission shaft 204 is provided with a long shaft 220. The lower side of the outer surface of the long shaft 220 and the transmission shaft 204 are connected in series through a synchronous chain B 221. The upper side of the outer surface of the long shaft 220 is fixedly provided with a spur gear 219. The spur gear 219 is engaged with an external tooth ring 217. The inner wall of the external tooth ring 217 is fixedly provided with a cleaning ring 218. The cleaning ring 218 is provided with cleaning bristles facing the lifting columns 6.

[0034] The upper end surface of the transmission rotating shaft 204 is fixedly provided with a lifting threaded rod 203, and the upper side of the transmission rotating shaft 204 is provided with a T-shaped lifting metal plate 201. The middle position of the upper end surface of the T-shaped lifting metal plate 201 is provided with a internally threaded through hole 202 penetrating through the T-shaped lifting metal plate 201, and the top end of the lifting threaded rod 203 is clamped into the internally threaded through hole 202 and is threadedly connected therewith. The bottom end of the transmission rotating shaft 204 located at the middle position of the inner side of the upper inclined metal base 222 is connected with a stepping motor 207 fixedly installed in the inner side of the upper inclined metal base 222, and the upper side of the stepping motor 207 is provided with an upper unloading surface strip-shaped cover plate located at the upper end surface of the upper inclined metal base 222, and the upper inclined metal base 222 and the upper inclined strip-shaped cover plate are fixed by screws. The stepping motor 207 can drive the transmission rotating shaft 204 connected therewith to rotate. When one of the transmission rotating shafts 204 rotates, all the transmission rotating shafts 204 connected in series through the synchronous sprocket 205 and the synchronous chain A 206 will rotate synchronously. When the transmission rotating shaft 204 rotates, the long rotating shaft 220 connected in series through the synchronous chain B 221 will also rotate. When the long rotating shaft 220 rotates, the spur gear 219 fixedly sleeved on the outer surface of the long rotating shaft 220 will also rotate. When the spur gear 219 rotates, the outer gear ring 217 engaged therewith will also rotate. When the outer gear ring 217 rotates, the cleaning ring 218 located on the inner wall thereof will also rotate. Through the cleaning bristles on the inner wall of the cleaning ring 218, the laser sensor 9 installed on the outer surface of the lifting column 6 in the lifting state can be cleaned and processed.

[0035] Both sides of the T-shaped lifting metal plate 201 are provided with a cylindrical groove 208. The upper side of the cylindrical groove 208 is provided with a circular limiting plate 209. The axis of the circular limiting plate 209 is connected with a jacking rod 210. The top end of the jacking rod 210 is fixedly connected with the lifting column 6. A spring A 211 is sleeved on the outer surface of the jacking rod 210.

[0036] Both sides of the inner wall of the receiving groove 7 are provided with a strip-shaped groove. Both the strip-shaped grooves are fixedly provided with a guide rod. A guide sleeve fixedly connected with the T-shaped lifting metal plate 201 is movably sleeved on the upper side of the outer surface of the guide rod. When the transmission rotating shaft 204 rotates, the lifting threaded rod 203 fixedly connected therewith will also rotate. Since the top end of the lifting threaded rod 203 is located in the internally threaded through hole 202 on the outer surface of the T-shaped lifting metal plate 201 and is threadedly matched therewith, when the lifting threaded rod 203 rotates, the T-shaped lifting metal plate 201 which cannot rotate by itself will move up and down. When the T-shaped lifting metal plate 201 moves upward, the lifting column 6 connected therewith through the jacking rod 210 will also rise. When the lifting column 6 cannot continue to move upward, but the T-shaped lifting metal plate 201 is still moving upward, the spring A 211 will be compressed.

[0037] The lower side of the outer tooth ring 217 is provided with an upper inclined surface ring 213 inside the concave metal plate 10, the two sides of the inner wall of the lower end of the upper inclined surface ring 213 are fixedly provided with a push block 212 above the T-shaped lifting metal plate 201, and the surface of the T-shaped lifting metal plate 201 facing the push block 212 is an inclined surface. When the lifting column 6 cannot continue to move upward, but the T-shaped lifting metal plate 201 continues to move upward, it will contact the push block 212, and with the lifting of the T-shaped lifting metal plate 201, the push block 212 and the upper inclined surface ring 213 fixed with the push block 212 will also rise.

[0038] The two sides of the upper inclined surface ring 213 are provided with a lower inclined surface block 214, and the surface of the upper inclined surface ring 213 facing the lower inclined surface block 214 and the surface of the lower inclined surface block 214 facing the upper inclined surface ring 213 are both inclined surfaces. One side of the outer surface of the lower inclined surface block 214 is connected with a spring B 215, and the outer side of the spring B 215 is provided with a circular spring anti-falling groove on the outer surface of the lower inclined surface block 214. An arc-shaped fixed strip 216 is arranged on the outer surface of the lower inclined surface block 214, and the position of the outer surface of the lifting column 6 facing the arc-shaped fixed strip 216 is provided with a ring-shaped fixed groove 11. In the process of rising of the upper inclined surface ring 213, it will contact the lower inclined surface block 214 and with the rising of the upper inclined surface ring 213, the lower inclined surface block 214 will be pushed inward, with the movement of the lower inclined surface block 214, the spring B 215 will be squeezed, and at the same time, the arc-shaped fixed strip 216 fixed with the lower inclined surface block 214 will be clamped into the inside of the ring-shaped fixed groove 11 on the lower side of the outer surface of the lifting column 6, so as to lock the ring-shaped fixed groove 11. When it is needed to retract the lifting column 6 and the partition plate 4 into the inside of the storage groove 7 and the strip-shaped storage groove 3, the stepping motor 207 is reversely driven to rotate the lifting screw rod 203, so as to make the T-shaped lifting metal plate 201 move downward. In the process of moving downward of the T-shaped lifting metal plate 201, the lower inclined surface block 214 will be pushed outward by the spring force of the squeezed spring B 215, with the movement of the lower inclined surface block 214, the arc-shaped fixed strip 216 fixed with the lower inclined surface block 214 will leave the inside of the ring-shaped fixed groove 11, so as to release the locking of the lifting column 6, and with the descending of the T-shaped lifting metal plate 201, the lifting column 6 connected with the T-shaped lifting metal plate 201 through the jacking rod 210 will also move downward.

[0039] A connecting rod is arranged between each lifting column 6 and the partition plate 4, and the two ends of the connecting rod are fixedly connected with the partition plate 4 and the lifting column 6 respectively. When the lifting column 6 moves up and down, the partition plate 4 will also move up and down through the connecting rod. When the lifting column 6 and the partition plate 4 move downward at the same time, they will gradually enter the inside of the storage groove 7 and the strip-shaped storage groove 3 respectively, so as to complete the storage.

[0040] It will be apparent to those skilled in the art that the application is not limited to the details of the above-exemplified embodiments and that the present application can be implemented in other particular forms without departing from the spirit or essential characteristics of the present application. The embodiments should therefore be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the above description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. No reference signs in the claims should be considered as limiting the scope of the claims with respect to the figures of the patent document.
