Description

Technical Field

[0001] The utility model belongs to the field of explosion-proof barrier structure design, and particularly relates to a combined explosion-proof barrier structure. Background Art

[0002] An explosion-proof barrier, also known as an explosion-proof turnstile, is a special turnstile system designed specifically for inflammable and explosive places. The explosion-proof barrier is an efficient, safe and intelligent device, mainly used to control the vehicle access in inflammable and explosive places, such as chemical plants, oil gas stations, natural gas storage areas, pharmaceutical factories, dangerous goods storage areas, etc. The explosion-proof barrier achieves the purpose of explosion protection by adding explosion-proof electrical appliances and special materials to the turnstile system. Its intelligent control system can automatically identify and control, such as sensing the arrival of a vehicle and automatically lifting and lowering the barrier rod to control the entry and exit of the vehicle.

[0003] Similar to the traditional barrier, the barrier arm of the explosion-proof barrier is generally integrally arranged and rigidly connected. Once it is hit by a vehicle, not only the barrier arm is easily damaged, but also the chassis part connected to the barrier arm will be damaged, resulting in irreversible damage and a high cost for repair and replacement. In addition, once a fault occurs in the circuit system of the existing explosion-proof barrier, the uncontrolled fall of the barrier arm is likely to cause damage to passing vehicles and itself, and the safety is poor. Therefore, it is very necessary to propose a combined explosion-proof barrier structure to solve the above problems. Summary of the Utility Model

[0028] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] Please refer to Figures 1 to 7 As shown, an embodiment of the present utility model provides a combined explosion-proof barrier gate structure, including a control chassis 1 and a barrier gate arm assembly arranged on one side of the control chassis 1. The barrier gate arm assembly includes a third short arm 5 of the barrier gate connected to one side of the control chassis 1. One end of the third short arm 5 away from the control chassis 1 is provided with a second short arm 4 of the barrier gate. One end of the second short arm 4 away from the third short arm 5 is provided with a first short arm 3 of the barrier gate. One end of the first short arm 3 away from the second short arm 4 is provided with a long arm 2 of the barrier gate. A first movable assembly is arranged between the second short arm 4 of the barrier gate and the third short arm 5 and between the second short arm 4 of the barrier gate and the first short arm 3 of the barrier gate. The first movable assembly includes a first flip plate 8 arranged at one end of the second short arm 4 close to the third short arm 5 and one end of the first short arm 3 close to the second short arm 4. A first flip groove 11 adapted to the first flip plate 8 is arranged on one side of the third short arm 5 and one side of the second short arm 4 of the barrier gate. The two first flip grooves 11 are arranged back to back. The first flip groove 11 is provided with a first pin shaft 7. One end of the first flip plate 8 extends to the inside of the first flip groove 11 and is rotatably connected to the first pin shaft 7. The rotation direction is horizontal rotation. In this embodiment, the barrier gate arm assembly is composed of a long arm 2 of the barrier gate, a first short arm 3 of the barrier gate, a second short arm 4 of the barrier gate, and a third short arm 5 of the barrier gate, and they are movably connected to each other. Among them, the connection between the second short arm 4 of the barrier gate and the third short arm 5 and the connection between the second short arm 4 of the barrier gate and the first short arm 3 of the barrier gate are horizontal rotational connections. Therefore, when the barrier gate arm assembly is impacted, it can automatically flip, which can greatly reduce damage.

[0030] Specifically, in this embodiment, when in use, if the barrier arm assembly of the device is impacted, it can automatically flip. Specifically, when one side is impacted, the whole of the long barrier arm 2, the first short barrier arm 3, and the second short barrier arm 4 can rotate horizontally in the direction of vehicle travel to provide protection. When the other side is impacted, the whole of the long barrier arm 2 and the first short barrier arm 3 also rotate in the direction of vehicle travel to provide protection. Since the two first flipping grooves 11 are arranged back to back, flipping protection can be achieved when either side is impacted.

[0031] Please refer to Figures 1 to 7 As shown, a second movable assembly is provided between the first short barrier arm 3 and the long barrier arm 2. The second movable assembly includes a second flipping groove 16 provided at the upper end of the first short barrier arm 3. The upper end and the end facing the long barrier arm 2 of the second flipping groove 16 are open. A second flipping plate 10 is provided at one end of the long barrier arm 2 close to the first short barrier arm 3. A second pin shaft 9 is provided inside the second flipping groove 16. One end of the second flipping plate 10 extends to the inside of the second flipping groove 16 and is rotatably connected to the second pin shaft 9, and the rotation direction is vertical rotation. The connection between the long barrier arm 2 and the first short barrier arm 3 is a vertical rotational connection, so as to avoid crushing the passing vehicles in case of a circuit system failure. When the long barrier arm 2 comes into contact with and is pressed by a vehicle, it can flip by itself.

[0032] Please refer to Figures 1 to 7 As shown, the first flipping plate 8 and the first flipping groove 11 are fixed by a first clamping assembly. The first clamping assembly includes first blind holes 15 provided at the top and bottom of the first flipping plate 8. The first blind holes 15 are movably connected with first clamping blocks 13. A first spring 14 is provided between the first clamping blocks 13 and the inner walls of the first blind holes 15. When the first spring 14 is in the initial state, the end of the first clamping block 13 away from the first spring 14 protrudes from the side wall of the first flipping plate 8. The protruding part of the first clamping block 13 is arc-shaped. First clamping grooves 12 corresponding to the first clamping blocks 13 are provided at the top and bottom of the inner cavity of the first flipping groove 11, and the first clamping blocks 13 are in clamping fit with the first clamping grooves 12.

[0033] Please refer to Figures 1 to 7 As shown, the second flipping plate 10 and the second flipping groove 16 are fixed by a second clamping assembly. The second clamping assembly includes second blind holes 18 provided on both sides of the second flipping plate 10. The second blind holes 18 are movably connected with second clamping blocks 19. A second spring 20 is provided between the second clamping blocks 19 and the inner walls of the second blind holes 18. When the second spring 20 is in the initial state, the end of the second clamping block 19 away from the second spring 20 protrudes from the side wall of the second flipping plate 10. The protruding part is arc-shaped. Second clamping grooves 17 corresponding to the second clamping blocks 19 are provided on both sides of the inside of the second flipping groove 16, and the second clamping blocks 19 are in clamping fit with the second clamping grooves 17.

[0034] Specifically, in this embodiment, when in use, the first clamping component and the second clamping component are used to increase the stability between the barrier arm components, and they will not rotate on their own easily. When pressed to a certain extent, the corresponding clamping structure can be unlocked automatically to achieve flipping. Specifically, when being impacted from the side, the first clamping block 13 on the first flipping plate 8 is pressed, the first clamping block 13 squeezes the first spring 14, and one end of the first clamping block 13 disengages from the first clamping groove 12, thus achieving flipping. When the barrier arm component is out of control, the long barrier arm 2 presses down on the vehicle and is pressed, so that the second clamping block 19 is pressed, the second clamping block 19 compresses the second spring 20 and disengages from the second clamping groove 17, thus achieving flipping.

[0035] Please refer to Figures 1 to 7 As shown, the buffer component includes a rubber plate 6 arranged below the long barrier arm 2. A guide post 21 is arranged at the top of the rubber plate 6. The longitudinal section of the guide post 21 is in a "T" shape. A third blind hole 23 corresponding to and adapted to the guide post 21 is arranged at the bottom of the long barrier arm 2. The upper end of the guide post 21 is movably connected to the inside of the third blind hole 23. A third spring 22 is arranged between the top of the guide post 21 and the inner wall of the third blind hole 23. When the long barrier arm 2 presses down, the rubber plate 6 at its bottom is in flexible contact with the vehicle, and the rubber plate 6 will compress the third spring 22 through the guide post 21, thus achieving effective buffering.
