Description

Technical Field

[0001] This utility model relates to the field of roadblock technology, and in particular to a mobile barbed wire roadblock. Background Technology

[0002] Barbed wire barriers consist of spikes set on spirally coiled steel wire. In setting up the barriers, the coiled barbed wire is typically stretched and placed on the road to achieve the effect of a roadblock. However, because the spikes on the surface of the barbed wire are quite sharp, it is easy to get injured when manually setting up the barbed wire. Therefore, setting up, retrieving, and moving barbed wire barriers is very inconvenient and time-consuming, affecting road traffic or the capture of criminals. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of the existing technology by providing a mobile barbed wire barrier.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: A mobile barbed wire barrier includes a vehicle body, the rear end of which is an open end; The fixing frame is fixedly connected to the vehicle body at one end and suspended at the rear end of the vehicle body at the other end. The end of the fixing frame at the rear end of the vehicle body has an arc-shaped structure. A support frame is connected to the fixed frame. A first chain is rotatably mounted on the support frame, and a lever is fixedly mounted on the first chain for the retrieval of the barbed wire. A power unit, located inside the vehicle body, is used to drive the first chain to rotate on the support frame.

[0005] Preferably, one end of the support frame is rotatably connected to the fixed frame, and the other end is connected to the fixed frame via a hydraulic cylinder.

[0006] Preferably, a first driving sprocket and a first driven sprocket are rotatably mounted on the support frame, the first chain is wound around the first driving sprocket and the first driven sprocket, and the first driving sprocket is connected to the power component for transmission.

[0007] Preferably, the power assembly includes a drive motor fixedly mounted on the fixed frame, a second drive sprocket rotatably mounted on the fixed frame and drivenly connected to the drive motor, a second driven sprocket rotatably mounted on the support frame, the second driven sprocket and the first drive sprocket being coaxially mounted, and a second chain being wound around the second drive sprocket and the second driven sprocket.

[0008] Preferably, one end of the actuating lever is fixedly connected to a fixing plate, and the fixing plate is fixedly connected to the first chain.

[0009] Preferably, protective doors are hinged to both sides of the vehicle body.

[0010] Preferably, a rear door is hinged to the rear end of the vehicle body, and a connecting rope connects the rear door to the vehicle body.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] like Figures 1 to 5 As shown, a mobile barbed wire roadblock includes a vehicle body 1 with an internal cavity for holding barbed wire. The front end of the vehicle body 1 is closed, and the rear end is open. Wheels are provided at the bottom of the vehicle body 1 to facilitate movement. A fixing frame 2 is installed inside the vehicle body 1. One end of the fixing frame 2 is fixedly connected to the front end of the vehicle body 1, and the other end is suspended at the rear end of the vehicle body 1. The fixing frame 2 is horizontally positioned and passes through the wound barbed wire, supporting the barbed wire. The end of the fixing frame 2 at the rear end of the vehicle body 1 has an arc-shaped structure and bends downward to facilitate the barbed wire sliding down from the rear end of the fixing frame 2 and being stored. A support frame 3 is installed on the fixing frame 2 and connected to it. The support frame 3 is located at the rear of the fixing frame 2. A first chain 4 is rotatably mounted on the support frame 3, and multiple levers 5 are fixedly mounted on the first chain 4. A power assembly is also installed inside the vehicle body 1 to drive the first chain 4 to rotate on the support frame 3.

[0020] In this invention, the rolled-up barbed wire is placed in the cavity inside the vehicle body 1. As the vehicle body 1 moves, the barbed wire can be quickly moved to the road where it needs to be deployed, making the movement of the barbed wire more convenient and faster. After the barbed wire is in place, it needs to be quickly deployed to form a roadblock. At this time, the barbed wire is set up on the fixed frame 2, and one end of the barbed wire can be pulled out. The barbed wire can quickly slide off the rear end of the fixed frame 2. During the process of the barbed wire sliding off, the vehicle body 1 moves forward synchronously. When the vehicle body 1 stops moving, the barbed wire no longer slides off, and the slid barbed wire forms a roadblock. Therefore, the roadblock deployment is convenient and quick, reduces human intervention, and can avoid injury to the deployment personnel. When the barbed wire is retrieved, the first chain 4 rotates on the support frame 3, and the first chain 4 drives the lever 5 to rotate synchronously. While the lever 5 is rotating, it can retract the deployed barbed wire roadblock into the vehicle body 1, realizing the rapid storage of the barbed wire.

[0021] Furthermore, such as Figure 4 As shown, one end of the support frame 3 is rotatably connected to the middle of the fixed frame 2, and the other end extends to the rear end of the fixed frame 2. The rear side of the support frame 3 is connected to the fixed frame 2 through a hydraulic cylinder 6. In this embodiment, the extension and retraction of the piston rod of the hydraulic cylinder 6 can cause the support frame 3 to rotate on the fixed frame 2. When the piston rod of the hydraulic cylinder 6 retracts, it causes the rear end of the support frame 3 to move downward, moving the actuating rod 5 to the bottom of the fixed frame 2, so that the top of the actuating rod 5 is lower than the top surface of the fixed frame 2, and the barbed wire can slide smoothly from the rear end of the fixed frame 2. When the barbed wire obstacle is retracted, the piston rod of the hydraulic cylinder 6 extends, driving the rear end of the support frame 3 to move upward, causing the actuating rod 5 to move to the top of the fixed frame 2. When the first sprocket 4 drives the actuating rod 5 to rotate, the barbed wire can be retracted into the vehicle body 1.

[0022] Furthermore, such as Figure 4 As shown, a first driving sprocket 7 and a first driven sprocket 8 are rotatably mounted on the support frame 3. A first chain 4 is wound around the first driving sprocket 7 and the first driven sprocket 8. The first driving sprocket 7 is connected to the power component for transmission. In this embodiment, the power component drives the first driving sprocket 7 to rotate, thereby enabling the first chain 4 to rotate between the first driving sprocket 7 and the first driven sprocket 8, driving the actuating rod 5 to rotate, and thus recovering the barbed wire.

[0023] It should be noted that there are two first driven sprockets 8, which are respectively rotatably mounted at the front and rear ends of the support frame 3. There is one first driving sprocket 7, which is rotatably mounted at the middle of the support frame 3.

[0024] Furthermore, the power assembly includes a drive motor 9 fixedly mounted on the mounting frame 2. The drive motor 9 is a geared motor. A second drive sprocket 10 is rotatably mounted on the mounting frame 2, and the second drive sprocket 10 is connected to the drive motor 9. The output shaft of the drive motor 9 is fixedly connected to the second drive sprocket 10, thereby driving the second drive sprocket 10 to rotate. A second driven sprocket 11 is rotatably mounted on the support frame 3. The second driven sprocket 11 and the first drive sprocket 7 are coaxially mounted, so both the second driven sprocket 11 and the first drive sprocket 7 are fixedly mounted on the same shaft. A second chain 12 is wound around the second drive sprocket 10 and the second driven sprocket 11. In this embodiment, when the drive motor 9 drives the second drive sprocket 10 to rotate, the second driven sprocket 11 rotates due to the transmission of the second chain 12. Since the second driven sprocket 11 is coaxial with the first drive sprocket 7, it can drive the first drive sprocket 7 to rotate, driving the first chain 4 and the actuating lever 5 to rotate, thereby recovering the barbed wire.

[0025] Furthermore, one end of the lever 5 is fixedly connected to a fixing plate 13, and two levers 5 are fixedly installed on each fixing plate 13. The two levers 5 are arranged in a "7" shape. The fixing plate 13 is fixedly connected to the first chain 4 by welding. There are multiple fixing plates 13, and the multiple fixing plates 13 are evenly arranged along the first chain 4.

[0026] Furthermore, such as Figure 2 As shown, protective doors 14 are hinged to both sides of the vehicle body 1. After the protective doors 14 are opened, it is convenient to observe and maintain the interior of the vehicle body 1. The protective doors 14 are equipped with grilles to facilitate ventilation inside the vehicle body 1.

[0027] Furthermore, a rear door 15 is hinged to the rear end of the vehicle body 1. A connecting rope, which is a chain, connects the rear door 15 to the vehicle body 1, and a buckle is provided between the rear door 15 and the vehicle body 1. In this embodiment, when the barbed wire needs to be deployed and stored, the buckle between the rear door 15 and the vehicle body 1 is opened, and the rear door 15 rotates downward until the connecting rope is tightened. At this time, the rear door 15 is tilted downward, and the barbed wire can slide on the rear door 15 when it falls from the vehicle body 1 and is retrieved, which facilitates the deployment and retrieval of the barbed wire. After the barbed wire is retrieved, the rear door 15 is closed and fixedly connected to the vehicle body 1 through the buckle. The rear door 15 can block the barbed wire in the vehicle body 1 and prevent the barbed wire from falling out of the vehicle body 1.

[0028] Furthermore, a connecting frame 16 is fixedly connected to the front end of the vehicle body 1. The connecting frame 16 is equipped with a hook to facilitate connection with the vehicle. During the movement of the vehicle body 1, the connecting frame 16 can be connected to the vehicle, and the vehicle can drive the vehicle body 1 to move quickly, so that the barbed wire roadblock can be quickly deployed on the designated road.

[0029] Furthermore, such as Figure 1 and Figure 6 As shown, the connecting frame 16 is equipped with a support assembly, which includes a connecting plate 17 fixedly mounted on the connecting frame 16. A rotating plate 18 is rotatably mounted on the connecting plate 17, and a rotating shaft is fixedly mounted at the center of the rotating plate 18. The rotating shaft is rotatably connected to the connecting plate 17, allowing the rotating plate 18 to rotate on the connecting plate 17. A support rod 19 is fixedly mounted on the rotating plate 18, and a roller 20 is rotatably mounted at the lower end of the support rod 19. In this embodiment, when setting up barbed wire barriers, the rotating plate 18 can be rotated to make the support rod 19 vertical, and the roller 20 rolls in contact with the ground, thereby providing a certain support function and facilitating the movement of the vehicle body 1. When transporting the vehicle body 1 by car, the rotating plate 18 is rotated to make the support rod 19 horizontal, and the roller 20 is removed from the ground, facilitating the transport of the car.

[0030] It should be noted that two locking holes are provided on the connecting plate 17. The angle between the line connecting the center point of the two locking holes and the center point of the rotating plate 18 is a right angle. A locking rod is slidably provided on the rotating plate 18, and a spring is provided on the locking rod. When the rotating plate 18 rotates to make the support rod 19 horizontal, the locking rod is inserted into one of the locking holes to prevent the support rod 19 from falling. After the locking rod is pulled out of the locking hole, the rotating plate 18 rotates to make the support rod 19 vertical, and the locking rod is inserted into the other locking hole, which can lock and fix the support rod 19 in a vertical state, so that the support rod 19 can support the vehicle body 1.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
