Description

  The present invention relates to a forced vehicle stop device, and more particularly, to a forced vehicle stop device for forcibly stopping a suspicious vehicle entering an important facility or building for improper purposes.

  Conventionally, in order to prevent suspicious vehicles from entering important facilities, etc., gates, gates, barricades, etc. have been installed near the entrance of the facility. If the vehicle rushes in, it may easily break down and cannot be an effective means for preventing suspicious vehicles from entering important facilities.

In addition, it is natural that vehicles that are normally allowed to enter and exit the facility are more likely to enter and exit, but in the case of the above gates and gate barricades, etc. Every time a permitted vehicle enters or exits, the gate or gate barricade must be blocked one by one, and in cases where the unblocked state is set as the default, an authorized vehicle can easily enter and exit, but it is a suspicious vehicle. It is difficult to make a transition to the closed state when the car has rushed at high speed.

  As described above, suspicious vehicle countermeasures such as gates and gate barricades are not likely to be countermeasures when large trucks rush at high speed, and are more reliable and reliable. Suspicious vehicle measures for important facilities are considered necessary.

  The present invention has been made in order to meet such a demand, and is normally held in an unblocked state, to an important facility or the like that can be immediately released upon unauthorized entry of a suspicious vehicle and shifted to a blocked state. It is an object of the present invention to provide a forced vehicle stop device.

  In order to solve the above-mentioned problems, the invention according to claim 1 is a pair of wire control units that are opposed to each other across a vehicle approach path, and that has a wire end that is fixed to the other, and the wire control unit. And a pair of wire lifting and lowering portions that support and support the intermediate portion of the wire and lift and lower the wire, and the wire lifting and lowering portion is based on an intrusion detection signal of a suspicious vehicle. It is proposed that the vehicle forcibly stop device is characterized in that the wire is raised from the road surface and hung on the suspicious vehicle, thereby forcibly stopping the suspicious vehicle.

  Preferably, the wire ascending / descending portion is driven by a spring, and the intrusion detection of the suspicious vehicle is performed by a sensor disposed behind the wire controller.

  Since the vehicle forced stop device according to the present invention has the above-described configuration, it can be normally kept in an unblocked state at the entrance of an important facility, etc. It is possible to immediately cancel the state and instantly shift to the blocked state to stop the intrusion of the suspicious vehicle.

  The best mode for carrying out the present invention will be described with reference to the accompanying drawings. FIG. 1 is a simplified side view of a vehicle forced stop device according to the present invention, FIG. 2 is a simplified plan view of one half thereof, and FIG.

  A vehicle forced stop device 1 according to the present invention is provided with a pair of wire control units 2 and 2 that are opposed to each other across a vehicle approach path, and an end of a wire 5 extending from one side is fixed to the other, and a wire control unit 2. 2 is composed of a pair of wire elevating parts 3 and 3 which are opposed to each other across the vehicle approach path and support an intermediate part of the wire 5 and raise and lower it. The wire elevating units 3 and 3 operate based on the intrusion detection signal of the suspicious vehicle to raise the wire 5 from the road surface, and hook the wire 5 on the suspicious vehicle to forcibly stop it.

  The ascending drive of the wire 5 in the wire lifting / lowering unit 3 may be performed by hydraulic pressure, pneumatic pressure, or the like, but the simplest method is to use the elastic force of the spring 6.

  In this case, for example, the spring 6 is housed in guide posts 7 and 7 that are opposed to each other across the vehicle approach path. In the guide posts 7 and 7, longitudinal grooves are formed over almost the entire length on the surfaces facing the wire control units 2 and 2 and the facing surfaces of the guide posts 7 and 7, and the wires 5 are passed therethrough. . The lower end of the spring 6 is fixed to the bottoms of the guide posts 7 and 7 positioned below the road surface, and the wire guide members 8 and 8 that freely move up and down in the guide posts 7 and 7 are fixed to the upper ends of the springs 6.

  A wire 5 introduced from one vertical groove is passed through the wire guide member 8, and the wire 5 is taken out from the other vertical groove and heads toward the other wire lifting / lowering unit 3. The wire guide members 8 and 8 move up and down in the guide posts 7 and 7 in accordance with the movement of the spring 6 described later to raise and lower the wire 5.

  The wire guide member 8 is a lock functioning so that the spring 6 is compressed and held in the lower portion of the road surface in the guide posts 7 and 7 during standby, and the compressed state is released based on the intrusion detection signal of the suspicious vehicle 20. It has a mechanism. The intrusion detection of the suspicious vehicle 20 is performed by the sensor 12 disposed near the wire control unit 2, 2, or behind it.

  The wire control units 2 and 2 are provided with at least one centrifugal brake 9 and 9a that pulls out the wire 5 and brakes the wire 5 when the wire 5 is pulled rapidly at a high speed (two in this embodiment). Has been deployed.)

  The rotating shafts of the centrifugal brakes 9 and 9a are pivotally supported on both side surfaces of the housing of the wire control unit 2, and at the front thereof, a height corresponding to a rising end of the wire 5 described later, that is, a height corresponding to a blocking position. A pulley 10 is attached, and one end of the wire 5 is fixed and wound on the rearmost centrifugal brake 9 via an intermediate centrifugal brake 9a of one wire control unit 2, and the other end of the wire 5 is connected to the opposite side. It is fixed and wound on the rearmost centrifugal brake 9 via an intermediate centrifugal brake 9 a of the wire control unit 2.

  In addition, when using several centrifugal brakes 9 and 9a like a present Example, in order to apply tension with respect to each centrifugal brake 9 and 9a and the pulley 10, it is preferable to arrange | position with a height difference. Moreover, the centrifugal brake 9 to which the rearmost wire 5 of at least one of the wire control units 2 is fixed is provided with a motor 11 for rewinding the wire 5 that has been pulled and sealed.

  The sensor 12 can detect at least the passage of the suspicious vehicle 20, and in addition to this, for example, a sensor using a speed authentication, a remote authentication system using an IC chip, or the like can be used.

  Next, the operation of the vehicle forced stop device 1 according to the present invention will be described. During normal times, the wire 5 is kept in an unblocked state, that is, in a state where the wire 5 is accommodated on a road surface or in a groove formed on the road surface (FIG. 3A). In this state, if the sensor 12 detects an abnormality as the vehicle passes, that is, if the sensor 12 tries to pass at a speed higher than the specified speed or if remote authentication by the IC chip is not performed, the sensor 12 When the detection signal is generated and the lock of the wire guide member 8 is released based on the detection signal, the compressed spring 6 is suddenly extended by the elastic force to push up the wire guide member 8, and the wire 5 is in a tension state. It is displaced to a position where it can be blocked (FIG. 3B).

  When the vehicle rushes toward the wire 5 as it is, the wire 5 is caught on the suspicious vehicle 20 and the wire 5 is pulled forward as it is (FIG. 3C), but each centrifugal brake 9 of the wire control unit 2 is pulled. , 9a controls the unwinding of the wire 5, and when the wire 5 is pulled out to some extent, the tension exceeds the rushing force of the suspicious vehicle 20, and the suspicious vehicle 20 is forcibly stopped.

  As mentioned above, although the optimal embodiment of the vehicle forced stop apparatus 1 which concerns on this invention was described, it cannot be overemphasized that this invention is not limited to this embodiment. For example, with regard to the mechanism for controlling the wire 5 of the wire control unit 2, if the wire 5 is pulled to some extent, but acts so as to act against the force to stop it, this is here Can be adopted.

  In the example shown in FIG. 4, the pulleys 15 and 15a are fixed to the cylinders 14 and 14a in place of the centrifugal brake 9, for example, two dampers 13 and 13a such as hydraulic dampers are provided with a height difference and the cylinders 14 and 14a. They are arranged so that their operating directions are reversed. In this case, the tip of the wire 5 is not a pulley but is fixed by driving a pile to the rearmost ground surface.

  In this case, when the wire 5 is pulled, the cylinder 14a of the front damper 13a is pushed up by the tension of the wire 5, and conversely, the cylinder 14 of the rear damper is pushed down. And if each cylinder 14 and 14a is pushed in to some extent, the force which stops pulling of the wire 5 by the repulsive force will work, and it will become possible to forcibly stop the suspicious vehicle 20 with the tension of the wire 5.

  Although the present invention has been described in some detail with respect to its most preferred embodiments, it will be apparent that a wide variety of different embodiments can be constructed without departing from the spirit and scope of the invention, the invention being defined by the appended claims. It is not restricted to the specific embodiment other than limiting in.
