Description

Technical Field

[0001] The utility model belongs to the technical field of tire puncturing devices, and particularly relates to a spherical hydraulic tire puncturing device. Background Art

[0002] A tire puncturing device, also known as a spike roadblock, barbed roadblock, etc., is a tire puncturing type vehicle blocking roadblock driven by a hydraulic power device, remotely controlled or wire-controlled. The spikes of the barbed roadblock are relatively sharp. When a vehicle tire runs over it, the tire will be punctured within 0.5 seconds and the gas in the tire will be emptied through the air vent holes, resulting in the vehicle being unable to move forward. Therefore, it is an essential anti-terrorism roadblock in some key security protection places. This roadblock is normally closed during operation, that is, during security operations, it is in the raised state to prevent any vehicle from passing. When a vehicle that can be released needs to pass, the spikes can be lowered manually by security personnel, and the vehicle can pass safely.

[0003] Chinese Patent with application number 2021114065020 discloses a high-strength fully automatic hydraulic tire puncturing device, including a drive box and a tire puncturing device main body. A partition plate is installed inside the drive box, a hydraulic motor is arranged at the bottom of the partition plate, the tire puncturing device main body is arranged on one side of the drive box, a top speed bump plate is installed at the top of the tire puncturing device main body, a plurality of tire puncturing knife racks are arranged inside the tire puncturing device main body, the tire puncturing knife racks are connected in series with each other through a first rotating shaft and a second rotating shaft, and a second gear is installed on one side inside the tire puncturing device main body through a hydraulic cylinder. This high-strength fully automatic hydraulic tire puncturing device is provided with a second tire puncturing tool. The second tire puncturing tool utilizes the meshing of the first gear and the second gear and the meshing of the second gear and the third gear, and then is driven to rotate by the hydraulic motor, and then passes through the top speed bump plate to achieve the interception effect, and intercepts vehicles in two directions respectively with the first tire puncturing tool.

[0004] The above solution has the advantage of improving the interception efficiency. However, like traditional tire puncturing devices, the power unit of the tire puncturing device was previously on one side of the device, and the limit length of the shaft it drives is relatively limited, with a limit length of about 6 meters. The power is a motor and a speed reducer, and the knife spikes are driven to lift and lower through the shaft. The disadvantage of this solution is that the torque is small, resulting in the inability of the knife spikes to quickly and effectively puncture the tire when dealing with heavy vehicles or high-tire-pressure tires, thus affecting the tire puncturing effect. Content of the Utility Model

[0005] To solve the above problems, the present utility model provides a hydraulic tire puncturer, which includes a tire puncturer body. A power box is provided at the middle bottom of the tire puncturer body. A speed bump plate is provided at the top of the tire puncturer body. A plurality of cutting openings are formed on the speed bump plate. A driving rotating shaft is provided inside the tire puncturer body. The driving rotating shaft is rotationally connected to both ends of the inner side of the tire puncturer body. A plurality of tire puncturing barbs are fixedly connected to the driving shaft. A power assembly is provided in the power box. The power assembly includes a hydraulic cylinder, a telescopic rod, a first cross bar, a first sector plate and a second sector plate. The tail of the hydraulic cylinder is hinged to the side wall of the power box. The output end of the hydraulic cylinder is connected with a telescopic rod. The end of the telescopic rod extends between the first sector plate and the second sector plate and is vertically connected with a first cross bar. Arc-shaped grooves are formed on the first sector plate and the second sector plate. Both ends of the first cross bar respectively extend into the arc-shaped grooves on the first sector plate and the second sector plate. The first sector plate and the second sector plate are both connected to the driving rotating shaft.

[0006] Preferably, the cross section of the driving rotating shaft is a hexagonal structure. A plurality of support plates are provided inside the tire puncturer body. U-shaped grooves are formed on the support plates. The driving rotating shaft is arranged in the U-shaped grooves.

[0007] Preferably, a limiting cap is threadedly connected to the end of the first cross bar.

[0008] Preferably, the tip angle range of the tire puncturing barbs is 30° to 45°.

[0009] Preferably, a first fixing plate and a second fixing plate are provided on the inner side arm of the power box. The tail of the hydraulic cylinder is vertically connected with a second cross bar. Both ends of the second cross bar are respectively rotationally connected to the first fixing plate and the second fixing plate.

[0010] The advantages of the present utility model are as follows:

[0011] 1. In this solution, the power unit is placed in the middle, which improves the driving limit length. The tire puncturer can cover a wider road surface, improving the efficiency and practicability of the equipment.

[0012] 2. Through the combination of the hydraulic cylinder and the telescopic rod in this solution, a greater thrust and torque can be generated compared with a motor and a speed reducer. This means that the new tire puncturer can respond more quickly and stably when lifting the puncturing barbs, and can also handle more complex road surfaces and vehicle tires.

[0013] 3. This solution makes the structure of the entire tire puncturer more compact and the layout more reasonable. This is beneficial to reducing the overall size and weight of the equipment, and improving the portability and maintainability of the equipment. Description of the Drawings

[0024] As Figure 1-2 shown, a hydraulic tire puncturer includes a tire puncturer body 1. A power box 2 is provided at the middle bottom of the tire puncturer body 1. The power box 2 is communicated with the tire puncturer body 1. The design of placing the power box 2 in the middle makes the structure of the whole tire puncturer more compact and the layout more reasonable. This is beneficial to reducing the overall size of the equipment, improving the portability and maintainability of the equipment. A speed bump plate 3 is provided at the top of the tire puncturer body 1. A plurality of cutting openings 4 are formed on the speed bump plate 3. A driving rotating shaft 5 is provided inside the tire puncturer body 1. The driving rotating shaft 5 is rotationally connected to both ends of the inner side of the tire puncturer body 1. A plurality of tire puncturing spikes 6 are fixedly connected to the driving shaft. The rotation of the driving rotating shaft 5 can drive the tire puncturing spikes 6 to rotate and lift. After the tire puncturing spikes 6 are lifted, they can puncture the passing vehicle tires. Placing the power unit in the middle can increase the driving limit length and drive the longer driving rotating shaft 5 to rotate, which means that the tire puncturer can cover a wider road surface, improving the efficiency and practicability of the equipment. In this embodiment, the tip angle range of the tire puncturing spikes 6 is 30° to 45°, preferably 40°. The angle range of 30° to 45° can ensure that when the spikes pierce the tire, they will neither be difficult to pierce due to too small an angle nor reduce the tire puncturing effect due to too large an angle. This design enables the spikes to quickly and effectively puncture the tire to achieve the purpose of blocking vehicle passage.

[0025] Combined with Figure 3-5A power assembly is provided in the power box 2, and the power assembly includes a hydraulic cylinder 7, a telescopic rod 8, a first cross bar 9, a first fan-shaped plate 10 and a second fan-shaped plate 11. A first fixed plate 16 and a second fixed plate 17 are provided on the inner arm of the power box 2. The tail of the hydraulic cylinder 7 is vertically connected with a second cross bar 18, and the two ends of the second cross bar 18 are rotatably connected with the first fixed plate 16 and the second fixed plate 17 respectively. Through the second cross bar 18 and the first fixed plate 16 and the second fixed plate 17, the hydraulic cylinder 7 can be hinged to the inner wall of the power box 2. The output end of the hydraulic cylinder 7 is connected with a telescopic rod 8, the end of the telescopic rod 8 extends between the first sector plate 10 and the second sector plate 11 and is vertically connected with the first cross bar 9, the first sector plate 10 and the second sector plate 11 are provided with an arc groove 12, the two ends of the first cross bar 9 extend into the arc groove 12 on the first sector plate 10 and the second sector plate 11 respectively, the end of the first cross bar 9 passes through the arc groove 12 and is threadedly connected to the limit cap 15, the threaded connection of the limit cap 15 can ensure a firm connection with the first cross bar 9, prevent loosening or falling off during the pushing process of the hydraulic cylinder 7, thereby enhancing the stability of the entire power assembly. The design of the arc groove 12 enables the first cross bar 9 to maintain a stable trajectory during the telescopic process, prevents displacement or shaking during the pushing process of the hydraulic cylinder 7, thereby enhancing the stability of the entire power assembly.

[0026] The first sector plate 10 and the second sector plate 11 are both connected to the driving shaft 5. The telescopic rod 8 and the first cross bar 9 are driven to reciprocate by the hydraulic cylinder 7, and the first cross bar 9 drives the first sector plate 10 and the second sector plate 11 to swing back and forth, thereby realizing the reciprocating rotation of the driving shaft 5 and the rotation and lifting of the tire puncturing knife 6. The combination of the hydraulic cylinder 7 and the telescopic rod 8 can generate greater thrust and torque than the motor and the reducer. This means that the new tire breaker can respond faster and more stably when lifting the knife, and can also cope with more complex road surfaces and vehicle tires. In addition, the transmission components of the hydraulic system are relatively simple and less worn, so the service life of the new tire breaker will be longer. At the same time, since the maintenance cost of the hydraulic system is relatively low, the maintenance cost of the equipment is also reduced.

[0027] Combination Figure 6, the cross-section of the driving rotating shaft 5 is a hexagonal structure. The hexagon has high structural strength and can provide better stability and load-bearing capacity. During vehicle driving and tire bursting, the hexagonal driving rotating shaft 5 can better resist impact and vibration, ensuring the stable operation of the tire burster. Inside the tire burster body 1, there are several support plates 13. The support plates 13 are provided with U-shaped grooves 14, and the driving rotating shaft 5 is arranged in the U-shaped grooves 14. First, the design of the support plates 13 of the U-shaped grooves 14 makes the installation of the driving rotating shaft 5 more convenient. Due to the open structure of the U-shaped grooves 14, the rotating shaft can be easily placed into the grooves and fixed by the support plates 13. This design reduces the installation difficulty and improves the work efficiency. Moreover, the cross-sectional shape of the U-shaped grooves 14 determines its high strength and rigidity, and can maintain shape stability. Placing the driving rotating shaft 5 in the U-shaped grooves 14 can ensure the stability of the driving rotating shaft 5 during rotation and reduce offset or damage caused by vibration or impact.

[0028] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
