Further, the runner is a twin runner composed of an enlargement wheel and a reduction wheel, wherein: the diameter of the enlarging wheel is larger than that of the reducing wheel. The amplifying wheel is arranged behind the reducing wheel in parallel, the circle centers of the amplifying wheel and the reducing wheel are fixedly connected through a connecting rod, and the groove is located in the side wall of the wheel surface of the amplifying wheel. Positioning pieces are arranged on two sides of the front wall surface of the reducing wheel, and the rotating main rod is horizontally fixed on the front wall surface of the reducing wheel through the positioning pieces.
Furthermore, the left side edge of the amplifying wheel is close to the left side wall of the control box, and the left side edge of the counterweight is flush with the left side edge of the amplifying wheel, so that the winding length of the traction wire is amplified by fully utilizing the inner cavity space of the control box, and the driving force required by the driving motor when the rotating main rod rotates upwards is reduced.

Further, the counter weight is the metal material, and it is fixed the left end tip of rotatory mobile jib to with the runner cooperation reduces required drive power when rotatory mobile jib is rotatory upwards.
Compared with the prior art, the invention has the following beneficial effects:
as mentioned above, some existing entrance guards have long lengths, which causes the problem that the entrance guard is difficult to lift due to large force arms and even causes insufficient motor power to drive the fence to turn over when the entrance guard turns over upwards, thereby increasing the operation difficulty of the entrance guard. Therefore, the entrance guard structure is redesigned, the driving force required by the rotation of the entrance guard is effectively reduced by adopting a new rotation mode, and the operation difficulty of large-specification entrance guards is reduced.
Firstly, the intelligent entrance guard management device adopts a telescopic fence type entrance guard structure, and the telescopic fence is installed by adopting the rotating main rod with a special structure, so that the telescopic fence can be automatically shortened in the process of lifting the rotating main rod, the gravity center of the telescopic fence is close to the rotating supporting point of the rotating main rod, the length of a rotating force arm is effectively reduced, the rotating main rod and the telescopic fence can rotate more easily, the driving force required by a driving motor is reduced, the requirement on the specification of the motor is reduced, and the operation difficulty of large-specification entrance guards is reduced. The reason for this is that: the rotary main rod is provided with a through groove and a track groove which are distributed along the length direction of the rotary main rod, the through groove penetrates through the upper surface and the lower surface of the rotary main rod, and the track groove penetrates through the front surface and the rear surface of the rotary main rod. The structure advantage of the rotary main rod is that the telescopic fence can be vertically installed in the through groove, and meanwhile, the rotating shaft at the center connection part of the rotary main rod can be used as a sliding shaft and matched with the rail groove, so that structural requirements are provided for the telescopic fence. Furthermore, the two ends of the telescopic fence are provided with the elastic parts, when the telescopic fence is shortened, the first elastic part is compressed, the energy stored by the compressed first elastic part can enable the telescopic fence to be quickly reset in the descending process, and when the telescopic fence descends to the horizontal position, the telescopic fence is reset, so that the synchronous descending and resetting of the telescopic fence are realized. In addition, the first elastic piece also plays a role in skillfully matching with the telescopic characteristic of the telescopic fence to ensure that the telescopic fence is in an extension state when being in a horizontal state and also plays a role in keeping the telescopic fence at a set position.
Furthermore, the entrance guard device adopts a mode that the rotary table and the driving motor are matched to drive the rotary main rod, and meanwhile, the traction line is connected with the rotating shaft at the middle connection part of the telescopic fence, so that the linkage among the telescopic fence, the traction line and the rotary table is skillfully realized through the rotary main rod with a special structure. When the driving motor drives the turntable to rotate, the traction wire can be wound on the turntable, and the telescopic fence can retract towards the direction of the turntable in the process, so that the telescopic fence rotates upwards, the gravity center of the telescopic fence is close to the rotating supporting point of the rotating main rod, the length of the rotating arm of force is reduced, and in addition, the counterweight can effectively reduce the driving force required by the rotation of the rotating main rod and the telescopic fence.
In addition, the intelligent entrance guard management device also adopts a more effective turntable which is a double-body rotating wheel formed by concentrically connecting an amplifying wheel and a reducing wheel. The double-body rotating wheel is characterized in that the amplifying wheel fully utilizes the inner space of the control box, so that the winding effect of the traction line is effectively amplified, the traction line can be stored as much as possible within a limited rotating angle of the amplifying wheel, the telescopic fence can be contracted as much as possible, the gravity center of the telescopic fence is closer to the driving motor, and the length of a rotating force arm is further reduced. Meanwhile, the reducing wheel is smaller than the amplifying wheel, so that the rotating main rod is fixed on the reducing wheel, the distance between the balance weight and the reducing wheel is larger, and the driving force required by the rotation of the rotating main rod and the telescopic fence can be effectively reduced. Meanwhile, the amplifying wheel is arranged behind the reducing wheel in parallel, so that the double-body rotating wheel with the special structure can not influence the connection of the balance weight and the rotating main rod while ensuring that the amplifying wheel plays an amplifying role in the winding effect of the traction line. In addition, the invention also utilizes the positioning parts arranged on the two sides of the front wall surface of the reducing wheel to horizontally fix the rotating main rod on the front wall surface of the reducing wheel, so that when the reducing wheel rotates, the positioning parts on the two sides of the front wall surface respectively press down and jack up the rotating main rod, thereby equivalently converting the traditional single-point drive into the double-point drive and effectively reducing the difficulty of the upward rotation of the rotating main rod and the telescopic fence.
In addition, the rotating wheel with the driving block is matched with the position relation between the balance weight and the rotating main rod, so that partial gravity center can be contracted before the rotating main rod and the telescopic fence rotate upwards. This is because: only when the driving block rotates to the position of the counter weight along with the rotating wheel, the counter weight can be pressed down and the rotating main rod is driven to carry the telescopic fence to rotate upwards. At the moment, because the turntable rotates for a certain distance, the traction wire is wound and contracted partially, and the gravity center of the telescopic fence at the moment is closer to the driving motor, so that the initial driving force required by the upward rotation of the rotating main rod and the telescopic fence can be effectively reduced, and the difficulty of the upward rotation of the rotating main rod and the telescopic fence is reduced. Simultaneously, adopt the drive block to push down the counter weight and make the required drive power of rotatory mobile jib mode of rotatory mobile jib upwards rotatory compare in directly adopting the carousel to drive and be littleer, can effectively reduce the degree of difficulty of rotatory mobile jib and flexible fence upwards rotation.
