Referring to fig. 16, in the interception net system 3, the driving mechanism further includes a second driving mechanism 38, a second driving mechanism mounting support 29 is disposed at the lower portion of the interception net module 25, the second driving mechanism 38 is mounted on the interception net module 25 through the second driving mechanism mounting support 29, and an output shaft of the second driving mechanism is connected to two ends of the adjacent interception net module 25, so that the adjacent interception net modules 25 can relatively slide in a telescopic manner to expand a proper barrier width to meet the barrier distribution requirement. Referring to fig. 17, the second driving mechanism 38 includes a driving motor, a driving shaft 40 and a cable 41, and the intercepting mesh modules 25 are driven by the cable 41 wound around the hydraulic motor 39 to extend and retract the intercepting mesh modules 25. For example, the hydraulic motor 39 and the driving shaft 40 are fixed on the first interception mesh module 25, one end of the wire rope guy 41 is fixed on one end of the second interception mesh module 25, the other end of the wire rope guy is fixed on the other end of the second interception mesh module 25, the middle of the wire rope guy is wound on the driving shaft 40, and the control unit 17 controls the hydraulic motor 39 to rotate so as to drive the second interception mesh module 25 to slide relatively through the wire rope guy 41; all of the second intercepting screen modules 25 are driven by the second driving mechanism 38 to perform a telescopic movement to deploy the required barrier width, which is not described in detail herein.

As shown in fig. 10-13, the blocking mesh modules 25 form a blocking wall when unfolded, and are folded at both sides of the main frame 14 as shown in fig. 9 after being completely retracted, so that the total width is not greater than the requirements of the relevant national standards, and the transportation driving requirements are met; the interception mesh module 25 can be partially expanded in a telescopic manner step by step as shown in fig. 10-11, or can be completely expanded as shown in fig. 12-13 to meet the requirements of different interception widths.

Referring to fig. 9, the bottom of each interception net piece module 25 is provided with a universal roller with a locking structure for greatly reducing driving resistance, when the travel of the steel wire rope inhaul cable 41 reaches a telescopic designated position, that is, when the interception net piece module 25 is expanded to meet the requirement of the interception width, the interception net piece module 25 limits the relative position through the locking structure and locks, if a fault occurs, the manual telescopic action can be realized only by separating the steel wire rope inhaul cable 41 from the interception net piece module 25, and the requirement of emergency barrier arrangement is met.

In the interception net system 3, the interception net piece module 25 comprises a main body frame 27 and an interception net 33 arranged on the main body frame 27, the main body frame 27 is formed by welding profiles such as rectangular steel pipes and the like, the main body frame 27 adopts a rectangular structure, and the stability of the main body frame 27 is improved by assisting a triangular structure; the main body frame 27 outside adopts the wire netting to cover, and every interception net piece module 25 is divided into a plurality of regions by main body frame 27, passes through the firm riveting of steel sheet and main body frame 27 with the multi-disc wire netting and is in the same place, and the wire netting adopts standard woven mesh preparation.

The upper part of the interception net piece module 25 is also provided with a movable interception net piece module 34, the top of the movable interception net piece module 34 is provided with an anti-climbing thorn 35, and people are prevented from climbing through roadblocks, so that the obstacle arrangement effect is enhanced. Each interception net piece module 25 is provided with a plurality of movable interception nets, the movable interception nets are slidably mounted in sliding grooves of a main body frame 27 structure, the extending or retracting of each interception net piece module is controlled by a fourth driving mechanism 28 on each interception net piece module 25, the fourth driving mechanism 28 controls the position of each movable interception net by adopting an electric push rod, and specifically, the control unit 17 controls the operation of the fourth driving mechanism 28 to drive the movable interception nets to slide, so that the movable interception nets have the reset positions hidden in the main body frame 27 and the interception positions extending out of the main body frame 27.

It can be described that when the barrier is laid, the electric push rod pushes the movable interception net to extend upwards, when the barrier is laid, the electric push rod retracts, the movable interception net is hidden in the main body frame 27, the electric push rod has a self-locking function, and when the driving is stopped, the movable interception net is automatically locked at a fixed position. If the electric push rod fails, the electric push rod can be pushed to a set height through manual operation and fixed through a pin.

In this embodiment, the rear portion of the intercepting mesh module 25 is provided with an auxiliary supporting mechanism 30, one end of the auxiliary supporting mechanism 30 is hinged with the main body frame 27, the other side is movably connected with a foldable or expandable supporting leg 31, the auxiliary supporting mechanism 30 can be folded at 90 degrees, when the intercepting mesh module 25 is retracted, the auxiliary supporting mechanism 30 is retracted in parallel with the main body frame 27 and is locked by a limiting mechanism; when the interception net piece module 25 is unfolded, the auxiliary supporting mechanism 30 is perpendicular to the main body frame 27, and the movable supporting legs 31 extend out of the supporting ground to form a triangular supporting structure with the main body frame 27, so that the stability of the interception net wall is enhanced.

The outer side of the intercepting net piece module 25 is riveted with a warning mark, such as' management and control area, forbid approaching! "" STOP! ' etc. are used for deterrence warning.

In the present embodiment, the electric power unit 16 of the interception net system 3 adopts a gasoline or diesel generator set to provide safe and reliable electric power for the electric motor of the interception net hydraulic station and the electric system of the interception net.

The intercepting net electrical system comprises an intercepting net expansion and other action control and warning lighting and speaking system, a positioning communication system and an auxiliary driving system; the interception net can be operated in three modes of an operation console, wireless remote control and wired remote control; the interception net system 3 can reserve an external power interface and can also use the power of the vehicle chassis 1 or external electric power.

The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
