When the drive motor is turned on, it will drive the anti-crossing lifting platform to extend upward in turn. When the anti-crossing lifting platform extends upward, the pedestrian can be blocked from crossing. At the same time, when the pedestrian leaves the two sides of the anti-crossing main body, the sensing signal generated by the infrared sensor will be disconnected. When the sensing signal generated by the infrared sensor is disconnected, the power control cabinet can be used to automatically control the drive motor to rotate in the opposite direction. When the drive motor rotates in the opposite direction, the anti-crossing lifting platform can be driven to automatically retract downward in turn, thereby realizing that the anti-crossing lifting platform will automatically extend to block pedestrians from crossing, and when the pedestrian leaves, it will automatically reset and retract.

[0014] 2. The utility model can also automatically control the sound and light alarm to sound and light alarm when the infrared sensor generates a sensing signal through the power control cabinet. When the sound and light alarm sounds the sound and light alarm, pedestrians can be warned. When the sensing signal generated by the infrared sensor is disconnected, the sound and light alarm can stop the sound and light alarm to avoid the sound and light alarm from making noise.

[0021] An installation cavity 3 is provided inside the anti-crossing main body 1, an inspection port 4 for inspecting the bottom of the installation cavity 3 is provided on the front side of the lower end of the anti-crossing main body 1, and the inspection port 4 is hinged with a sealing door, a power control cabinet 5 is fixedly installed at the bottom of the installation cavity 3, and a mobile power supply is fixedly installed inside the power control cabinet 5, a connection port 6 for connecting the mobile power supply inside the power control cabinet 5 is fixedly installed through the side edge of the lower end of the anti-crossing main body 1, a driving motor 7 is fixedly installed on the side end support of the bottom of the installation cavity 3, a main shaft 8 is fixedly installed on the inner transmission shaft part of the driving motor 7, and the main shaft 8 is rotatably connected to the installation cavity through a shaft at the top end away from the driving motor 7. 3 inner wall, the outer curved surface of the main rotating shaft 8 is fixedly installed with a first bevel gear 9, and there are several first bevel gears 9, which are symmetrically distributed with the outer curved surface of the main rotating shaft 8, the upper end of the first bevel gear 9 is meshed and connected with the second bevel gear 10, the upper end of the second bevel gear 10 is fixedly installed with an internal thread support tube 11, and the lower end of the internal thread support tube 11 is fixedly supported and rotatably connected to the inner wall of the middle part of the installation cavity 3, the upper top of the installation cavity 3 is provided with a limiting hole 12, and the outer curved surface of the upper end of the internal thread support tube 11 is movably connected to the inner wall of the limiting hole 12, the inner wall of the internal thread support tube 11 is threadedly connected with a support screw 13, and the upper top of the support screw 13 is fixedly installed with an anti-crossing lifting platform 14;

[0022] Sound and light alarms 15 are fixedly installed on both sides of the upper end of the anti-crossing lifting platform 14, and there are two sound and light alarms 15, which are symmetrically distributed on both sides of the upper end of the anti-crossing lifting platform 14. Mounting ramps 16 are fixedly installed on the front and rear side walls of the anti-crossing main body 1, and there are four mounting ramps 16, every two mounting ramps 16 form a group, and the two groups of mounting ramps 16 are symmetrically distributed on the front and rear side walls of the anti-crossing main body 1. An infrared sensor 17 for sensing pedestrians is fixedly installed on the outer end of the mounting ramp 16.

[0023] Working principle: When in use, the utility model pushes the anti-crossing main body 1 to the municipal road where the anti-crossing is required. When the anti-crossing main body 1 is pushed to the municipal road where the anti-crossing is required, the universal roller 2 is locked. When the universal roller 2 is locked, the anti-crossing main body 1 can be locked and fixed;

[0024] When the anti-crossing main body 1 is locked and fixed, the infrared sensor 17 is controlled to be turned on to sense pedestrians on both sides of the anti-crossing main body 1. When pedestrians appear on both sides of the anti-crossing main body 1, the infrared sensor 17 will generate a sensing signal. When the infrared sensor 17 generates a sensing signal, the power control cabinet 5 can be used to automatically control the start of the drive motor 7. When the drive motor 7 is turned on, it will drive the main shaft 8 to rotate. When the main shaft 8 rotates, it will drive the first bevel gear 9 to rotate. When the first bevel gear 9 rotates, it will mesh and drive the second bevel gear 10 to rotate. When the second bevel gear 10 rotates, it will drive the internal threaded support tube 11 to rotate. When the internal threaded support tube 11 rotates, it will drive the support screw 13 to rotate with the internal thread. The force generated by the threaded connection of the inner wall of the grooved support tube 11 moves upward. When the support screw 13 moves upward, it will drive the anti-crossing lifting platform 14 to extend upward. When the anti-crossing lifting platform 14 extends upward, it can prevent pedestrians from crossing. At the same time, when pedestrians leave the two sides of the anti-crossing main body 1, the induction signal generated by the infrared sensor 17 will be disconnected. When the induction signal generated by the infrared sensor 17 is disconnected, the power control cabinet 5 can automatically control the start of the drive motor 7 to rotate in the reverse direction. When the drive motor 7 rotates in the reverse direction, it can drive the anti-crossing lifting platform 14 to automatically retract downward in turn, so that the anti-crossing lifting platform 14 can automatically extend to prevent pedestrians from crossing, and when the pedestrians leave, it will automatically reset and retract.

[0025] At the same time, when the infrared sensor 17 generates a sensing signal, the power control cabinet 5 will automatically control the sound and light alarm 15 to start the sound and light alarm. When the sound and light alarm 15 sounds the sound and light alarm, pedestrians can be warned. When the sensing signal generated by the infrared sensor 17 is disconnected, the sound and light alarm 15 can stop the sound and light alarm to avoid the sound and light alarm 15 from generating noise by continuously sounding the sound and light alarm.
