As shown in Figure 2, the head of each cable-discharge box 1 is provided with a first fixed pulley block 11 for positioning, and the tail of each cable-discharge box 1 is provided with an overload protector 12, and each A primary load protector 13, a hydraulic device 14 and a second fixed pulley block 15 adjacent to the overload protector 12 are arranged in the cable energy release box 1, and an initial load protector 13 and the hydraulic device 14 are provided There is at least one first fixed pulley 16, at least one second fixed pulley 17 is arranged between the hydraulic device 14 and the second fixed pulley block 15, the first fixed pulley block 11, the initial load protector 13, the first fixed pulley 16. The hydraulic device 14, the second fixed pulley 17 and the second fixed pulley block 15 are sequentially connected by the steel wire rope 2 in the cable energy-discharging box 1, and the steel wire rope 2 in the cable energy-discharging box 1 is passed through the first fixed pulley block 11. The tail end 22 of the steel wire rope 2 in the cable energy release box 1 is connected to the overload protector 12.

Among them, the initial load protector 13 is to protect the steel wire rope 2, specifically, because the steel wire rope 2 is likely to be broken under a sudden heavy load in a relaxed state, and the initial load protector 13 can share this part when the steel wire rope 2 suddenly bears a heavy load Heavy load, thereby playing the role of protecting the steel wire rope 2; the overload protector 13 is used to protect the hydraulic device 14, when the kinetic energy of the traveling vehicle being blocked exceeds the range that the hydraulic device 14 can prevent consumption, the overload protector 14 The load consumes the remaining kinetic energy. If the overload protector 14 cannot consume the remaining kinetic energy, the overload protector 14 loosens the steel wire rope 2; the hydraulic device 14 is used to consume the kinetic energy of the running vehicle; the first fixed pulley block 11 and the second fixed pulley block 15 are all used for positioning the energy-discharging rope section 21 of the steel wire rope 2; the first fixed pulley 16 and the second fixed pulley 17 all play a guiding role.

Referring to Fig. 2 again, the hydraulic device 14 includes a plurality of one-way damping hydraulic cylinders 141 arranged side by side, at least one third fixed pulley 142 is arranged between two adjacent one-way damping hydraulic cylinders 141, and each one-way damping hydraulic cylinder 141 A fourth fixed pulley 143 is provided on the operating end of the piston rod 1411 , and the third fixed pulley 142 and the fourth fixed pulley 143 are connected through the energy-releasing rope segment 22 .

The utility model can be arranged on necessary roads for a long time, such as downhill places where accidents often occur; it can also be temporarily arranged at a crossing as required. During the operation of the utility model, a plurality of blocking groups 100 are arranged at intervals, that is, multiple lines of defense are set, and one blocking group 100 constitutes a line of defense, and the operation process of each blocking group 100 is: 1. Find reliable roads on both sides of the road. Fixtures, if not, just drive into steel drills and other things in situ to make on-site fixtures 200; 2, hang the fixed anchor 5 of the cable energy-discharging box 1 on the spot fixtures 200 and fix them; 3, block as desired Object (vehicle) height adjusts the height of support 4, adjusts the length of arresting cable 3 according to road width, then the two ends of arresting cable 3 are respectively stuck on two fast rope connectors 3, and arresting cable 3 is not on the road now. Affect the passage of non-target vehicles, when the target vehicle appears, put the support 4, and set up the arresting cable 3 on the support 4 to block.

The working principle of each blocking group 100 is as follows: after the target vehicle touches the blocking cable 3, it pushes forward against the blocking cable 3, and the blocking cable 3 is naturally disengaged from the support 4, and then the fast rope connector 3 is pulled to release the blocking cable. The steel wire rope 2 in the original slack state in the energy box 1, the huge pulling force is transmitted to the initial load protector 13 through the steel wire rope 2, and the part is removed by the initial load protector 13, and then the steel wire rope 2 enters a tight state. Further being pulled, each one-way damping hydraulic cylinder 141 in the hydraulic device 14 is pressed (each one-way damping hydraulic cylinder 141 has adjusted the corresponding damping value in advance according to the target vehicle), thus each one-way damping hydraulic cylinder 141 consumes the motion The kinetic energy of the target vehicle during driving makes the vehicle stop softly. If the kinetic energy of the target vehicle is very large, and each one-way damping hydraulic cylinder 141 has reached its end, then the overload protector 14 bears and consumes the remaining kinetic energy, thereby blocking the target vehicle; Device 14 also can't consume remaining kinetic energy, then following two situations occur:

When the wire ropes 2 in each blocking group 100 independently adopt one line of defense, that is, each line of defense is arranged in parallel, the overload protector 14 relaxes the wire rope 2, and the blocking rope section 22 of the wire rope 2 falls off from the target vehicle, and the line of defense completes its mission; One blocking system shares one steel wire rope 2, that is, when each line of defense is set in series, the steel wire rope 2 behind the tail of the cable energy-discharging box 1 in the first line of defense partially pulls the hydraulic device in the cable-blocking energy-discharging box 1 in the second line of defense 14. Implement the target vehicle to continuously discharge energy against the wire rope 2, and finally be stopped. Among them, the series connection of each line of defense is suitable for long-term installation on necessary roads, while the parallel connection of each line of defense is more suitable for temporary installation.

After the blocking task is completed, open the box body of the cable-blocking energy-discharging box 1, and since it is a one-way damping hydraulic cylinder 141, the one-way damping hydraulic cylinder 141 can be manually restored to an elongated state, and the steel wire rope 2 can be adjusted for reuse .

In summary, the utility model can be quickly deployed at the site of use without taking a long time for deployment; the system is simple and easy to carry, and can be applied to most situations that require blocking; The cooperation of steel wire ropes and brackets in the blocking group can effectively block the vehicles in motion; using the blocking cable to block, the blocking cable can be quickly released from the vehicle when the blocking is released, and the vehicle can be avoided. In addition, the blocking system will not cause the tires to be scrapped during the blocking process, that is, it will not cause waste of resources.
