  The present invention relates to a vehicle intrusion prevention device for forcibly stopping a vehicle that has illegally entered an unauthorized entry prohibited area such as an airport or a nuclear power plant.

  In general, censor gates (guardhouses, etc.) are installed in areas where important facilities such as airports and nuclear power plants are prohibited from unauthorized entry, and illegally intruding vehicles such as trucks that have broken through the censor gate are forcibly stopped. For this purpose, a barricade made of steel bollards, drums, or steel plates is installed at a road blocking location in an unauthorized entry prohibited area, for example, so that it can be raised and lowered, and the barricade is driven up and down by hydraulic or electric remote control means. A vehicular intrusion prevention device having a configuration is already known. In such a conventional vehicle intrusion prevention device, the impact force of the illegally intruding vehicle is received only by the barricade that is suddenly raised to the road blocking position of the unauthorized intrusion prohibited area when the illegally intruding vehicle crushes the censor gate. The barricade is composed of a rigid body that is strong enough to make the rushing vehicle wrecked.

  The above prior art is a technique generally known to those skilled in the art, and does not relate to a known literature invention.

  Since the conventional vehicle intrusion prevention device is configured as described above, it is possible to prevent the entry of illegally intruding vehicles by a barricade made of a high-strength rigid body. However, the barricade of a high-strength rigid body has a buffer function in the event of a vehicle collision. There is a problem that no consideration is given to the life protection of the driver or passenger of the collision vehicle.

  The present invention has been made to solve the above-described problems, and provides a vehicle intrusion prevention device that can prevent the intrusion of an illegally intruding vehicle and contribute to the life protection of the driver and passengers of the intruding vehicle. The purpose is to obtain.

  A vehicle intrusion prevention device according to the present invention is installed on a roadbed in an unauthorized intrusion prohibited area, and rises on the road surface to block a path of an illegally intruding vehicle, and descends from the ascent position to allow a vehicle permitted to pass.

In FIG. 1, reference numeral 1 denotes an important facility such as an airport or a nuclear power plant. The site of the important facility 1 is an unauthorized entry prohibited area, and a guardhouse 2 is provided at the entrance of the prohibited entry area. ing. An illegal intrusion vehicle 4 such as a truck that has forcibly broke through the guard station 2 is prevented from entering the important facility 1 on a road (roadbed) 3 in an unauthorized entry prohibited area from the guard station 2 to the important facility 1. For this purpose, a vehicle intrusion prevention device 10 is installed. The vehicle intrusion prevention device 10 is installed on the roadbed 3 in the unauthorized entry prohibition area, rises on the road surface, blocks the path of the illegally intruding vehicle 4, and descends from the ascent position to perform normal vehicle travel (traffic A movable barricade 11 that is driven up and down to a lowered position that allows the vehicle to travel (permitted vehicle), and a road surface before the path blocking position of the illegally intruding vehicle 4 by the barricade 11 is provided on the road surface before the illegally intruding vehicle 4. The wheel drop hole 13 for dropping the front wheel 4a is combined.

  More specifically, the barricade 11 is pivotally supported by a hydraulic cylinder (barricade driving means) 12 so as to be rotatable in a direction rising from a barricade storage groove formed on a road surface of a barricade installation place on a road in an unauthorized entry prohibition area. It consists of a movable fence member made of iron plate that is driven up and down. On the other hand, an opening / closing lid 14 is attached to the opening of the wheel drop hole 13. As shown in FIG. 2, the opening / closing lid 14 is supported on the inner wall of the opening of the wheel drop hole 13 via a horizontal pin P, and from the position where the opening of the wheel drop hole 13 is closed with the horizontal pin P as a rotation center. The wheel can be turned in the direction of falling by its own weight inside the wheel dropping hole 13. Thus, the opening / closing lid 14 rotatably supported on the inner wall of the opening of the wheel drop hole 13 by the horizontal pin P is formed by the lid lock holding mechanism 15 on the same plane as the road surface at the opening closing position of the wheel drop hole 13. The lock is held.

It is possible to run the vehicle. In such a normal state, when the illegally intruding vehicle 4 forcibly breaks through the censor gate at the guard station 2, if the operation button 19 is turned on at the guard station 2, the hydraulic device of the barricade 11 drive system from the control panel 20 is turned on. A control signal is output to each of 21 and the lid lock holding mechanism 10, and the hydraulic cylinder 12 is extended and operated by the hydraulic oil supplied from the hydraulic device 21 to the hydraulic cylinder 12 by the control signal. As a result, the barricade 1 rotates and rises from the road surface of the road 3 and is held upright at a position where the path of the illegally intruding vehicle 4 is blocked. The latch receiver 17 of the lid lock holding mechanism 15 is rotated in the disengagement direction with respect to the latch 16 (rotation direction indicated by an arrow a in FIG. 3C) in synchronization with the ascent operation of the barricade 11. The lock holding of the open / close lid 14 by the lid lock holding mechanism 15 is released. The open / close lid 14 whose lock is released is lowered and rotated by its own weight with the pin P (see FIG. 2) as its center of rotation, and hangs down in the wheel drop hole 13, thereby opening the wheel drop hole 13 (FIG. 4). (See (B)).

  In this way, when the barricade 11 is raised on the road surface of the road 3 when the illegally intruding vehicle 4 is forced to enter, the opening / closing lid 14 is pivoted downward to open the wheel drop hole 13, so that the important facility 1 can be opened. In the illegally intruding vehicle 4 rushing toward the front, the front wheel 4 a falls into the wheel dropping hole 13 before the collision with the barricade 11 blocking the course. The bumper 4b at the front of the vehicle body of the illegally intruding vehicle 4 rubs on the road surface between the barricade 11 and the wheel drop hole 13 due to the depression, so that the illegally intruding vehicle 4 before the collision with the barricade 11 is braked.
