Abstract

An apparatus for inhibiting the passage of foreign vehicles through a specific area while allowing the passage of approved, approved and designated vehicles, which is composed of at least one standard element that can be reused and simultaneously put in place, thereby eliminating the need for special facilities. The module comprises a blocking plate (13) which is activated by means of an operating lever (14) in a release mechanism (9) (11) (17) (18) controlled by the operating lever (11) and the catch (2) and which lifts the catch (2) by means of a sliding rod (16) exerting pressure on the sliding rod (9) which pushes the catch (7), all of said elements being connected to the chassis (1).

Description

The invention relates to a combined anti-intrusion barrier, which is used to control land vehicles to allow or prohibit passing through some specific areas. It does not require any special equipment to effectively control existing or upcoming intersections.

This kind of barricade can be simply placed on the ground, of course, it is better to be fixed on the ground. When some vehicles forcibly invade, it shows its necessity. In the case of allowing passage, because this kind of roadblock is relatively short, it will not cause obstacles to passing vehicles, but they must be slowed down.

The standard parts that make up it can be put together one by one according to the size of the entrance to be protected, and then connect them together through the connecting device.

At present, the entrance control of some specific areas is mainly realized by the following methods:

- Articulate some obstacles like liftable arms on a horizontal axis.

- Arranging a mast with one or more pivotable baffles in a vertical direction.

- Movable door frame, etc.

In order to control the vehicle more effectively, these control barriers are often supplemented by the following obstacles: drop gates, stop fences, shaft pits, etc. However, these facilities require large-scale civil construction, and external power is required for manipulation. Where vehicles break into, safety protection measures are also required. More importantly, the action of these obstacle systems is too slow, which affects its use effect.

The object of the present invention is to provide an anti-intrusion roadblock, which can minimize the entire action time (about 1/10 second) when a vehicle breaks in, and only needs to rely on the power provided by the vehicle intruding, and at the same time No safety protection device is required.

The anti-intrusion barricade of the present invention comprises: a bottom frame that is horizontally arranged on the road surface; Movement between a lowered position and a raised position; characterized in that, viewed in the direction of travel of the vehicle, the control baffle is located upstream of the stop baffle, and they are connected by a linkage release mechanism so that when vehicles that are prohibited from passing When the control baffle in the raised position is knocked down, the stop baffle in the lowered position can be released, so that the stop baffle can be lifted up rapidly under the action of elastic force, thereby preventing the vehicles passing through the control baffle from passing .

The linkage release mechanism may comprise a horizontally sliding push rod, one end of the push rod can release a lock bolt on the stop baffle in the lowered position, and the other end is hinged to a control slide rod, The control slider can move to a raised position and a lowered position under the action of a joystick. In the lowered position, the control slider can directly contact with a push-out slide rod, and the push-up slide rod is in the control position. The plate locks rigidly with it as it is lowered to release the latch when the control fence is knocked down and thereby cause the stop fence to be raised upwards by the use of a strong mechanical spring. The control slide may be permanently biased toward its lowered position by a spring. In addition, the control baffle and the ejection slide connected to it can be controlled on one control lever.

Once loaded, this anti-intrusion barrier can release powerful energy by itself and complete the entire action in an instant.

An embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings.

Fig. 1 shows the state when the roadblock of the present invention allows vehicles to pass through;

Fig. 2 shows the state when the roadblock of the present invention prohibits vehicles from passing.

The barricade according to the invention comprises a chassis 1 onto which vehicles can run by means of a ramp. Underframe 1 height is very little, is formed by mechanical welding. On the base frame 1 , hinged via an axis 3 , is a metal drop door 2 with one or more arms serving as a stop. These arms extend outward and are connected to each other by a wooden support, like the tines of a rake. The locking bolt 4 fixed on the arm bar can be buckled under the lock catch 7 to keep the arm bar level (as shown in Figure 1). The lock catch 7 can move back and forth as shown by the arrow in Figure 2, and when it moves to the position shown in Figure 2, the lock bolt 4 is released, and the hanging door 2 will be pushed to the raised position by the compressed spring 5 (as shown in Figure 1 shown), the highest raised position is limited by the adjustable stop device 6. The lock catch 7 can be pushed by a push rod 18 sliding in the slideway 10 to move against the action of the spring 8 to the position for releasing the lock bolt 4 . As shown in the figure, the left end of the push rod 18 pushes the lock 7 , while its right end is hinged to the shaft 17 of the control slide bar 9 . The control slide 9 can be moved to the raised position shown in FIG. 1 or the lowered position shown in FIG. 2 under the actuation of the joystick 11, and it is always biased towards its lowered position by the spring 12. Members 9, 11, 12 and 17 form a release mechanism.

Viewed along the direction of travel of the vehicle, upstream of the hanging door 2, a control baffle 13 is provided on the underframe 1, which can be driven by a control rod 14 and rotate around a shaft 15 to the lowered position shown in FIG. 1 or in FIG. 2. Raised position shown by dotted line. Also hinged on the shaft 15 is a push-out slide bar 16, which slides along the bottom surface of the underframe 1 under the drive of the control rod 14, and can engage with the control slide bar 9 in the descending position (as shown in Figure 2). In this way, the movement of the control rod 14 or the control baffle 13 can be transmitted to the push rod 18 through the two slide rods 16 and 9, thereby pushing the lock catch 7 away from the locked position, so that the hanging door 2 is bounced.

The working process of the roadblock of the present invention is described in detail below.

The barricade first needs to be placed in a loading or active state. Utilize the control lever 14 to make the control baffle 13 be in the upright position shown by the dotted line in Fig. 2, and resist the elastic force of the spring 5 to press the hanging door 2 downward until the lock catch 7 and the lock bolt 4 are locked, at this time the hanging door 2 will be It is in a horizontal position flush with the bottom frame 1 (as shown in Figure 1). After this, can pass joystick 11 and control lever 14 Control the crossing to realize safety protection.

When allowing vehicles to pass through, the guard first pulls the joystick 11 to the position shown in Figure 1, so that the control slide bar 9 is lifted; Since the control slide bar 9 has been lifted in advance, the push-out slide bar 16 does not contact the slide bar 9 when carrying out the latter operation, but slides from below it. Through the above operations, the vehicle can pass through without hindrance.

If vehicles are prohibited, the guardian does not need to take any action.

If the vehicle forcibly passes and knocks down the control baffle plate 13, the push-off slide bar 16 moves to the left and immediately pushes the control slide bar 9, and then drives the push rod 18 to push the lock catch 7 to the position of releasing the hanging door 2, so that the hanging door 2 will rise up quickly under the action of spring 5 (as shown in FIG. 2 ), thereby effectively preventing vehicles that have broken through control baffle 13 from passing.
