Description

Technical Field

[0001] This invention relates to the field of traffic barrier technology, and more particularly to a movable and liftable road barrier. Background Technology

[0002] Manually moving conventional spherical stone bollards is time-consuming and labor-intensive. These bollards, made of concrete or stone, are extremely heavy, making manual movement inefficient and posing a significant risk of back sprains or limb injuries to workers. Even with simple tools like crowbars and hydraulic pallet trucks, their bulky shape and rough surfaces often scratch precious asphalt or marble paving, leaving permanent, irreparable marks. A more pronounced contradiction lies in the difficulty of quickly opening passages in emergency situations such as sudden traffic disruptions, medical emergencies, or disaster relief. Once set up, these bollards struggle to respond quickly to sudden traffic demands, highlighting the dilemma of balancing dynamic control with rigid isolation in urban management. Summary of the Invention

[0003] To address these issues, we propose a movable and liftable road barrier, which solves the problems of existing spherical stone bollard road barriers having limited functionality, being unable to move flexibly, and being difficult to adapt to different scenarios.

[0004] This invention proposes a movable and liftable road barrier, characterized in that it includes: a road barrier body, a lifting device, and a movable pulley; the lifting device is provided at the bottom of the road barrier body, and the movable pulley is connected below the lifting device. When the road barrier needs to be moved, the movable pulley extends out of the road barrier body by adjusting the lifting pedal device, thereby realizing the flexible movement of the road barrier.

[0005] Furthermore, the bottom of the roadblock body is provided with multiple lifting operation holes, which are evenly distributed in a ring around the roadblock, and the lifting device is installed and fixed inside the lifting operation holes.

[0006] Furthermore, the lifting device includes: lifting outriggers, a lifting control plate, and an adjusting pedal. Each lifting outrigger is installed in each of the lifting operation holes. The lifting control plate is installed at the bottom of the roadblock body and has corresponding lifting operation holes. The lifting control plate is connected to each of the lifting outriggers. A synchronization controller is installed on the lifting control plate to control the synchronized lifting of each of the lifting outriggers. A pedal groove is opened at the lower end of the roadblock body and communicates with the bottom of the roadblock body. The pedal groove is opened on the surface of the roadblock body and is a certain distance away from the bottom of the roadblock body. The control pedal is installed in the pedal groove.

[0007] Furthermore, the lifting outrigger includes a hydraulic rod and a cylinder. The cylinder is sleeved outside the hydraulic rod, and the cylinder and both ends of the hydraulic rod are sealed together. One end of the hydraulic rod is fixed inside the lifting working hole, and one end of the cylinder is connected to the movable pulley. The lifting outrigger is equipped with an oil inlet valve and an oil return valve. The oil inlet valve and the oil return valve of each lifting outrigger are connected to the oil pipe of the lifting control board. The lifting control board is connected to the oil tank through the oil pipe. The oil tank is fixed inside the road barrier body. The synchronous controller controls the synchronous lifting and lowering of the lifting outrigger by controlling the oil volume in the oil pipe.

[0008] Furthermore, the adjusting pedal includes: a control pedal, a pressure sensor, and a connecting fixing plate. The control pedal is mounted and fixed on the road barrier body via the connecting fixing plate. The control pedal is provided with a connecting bearing, and the connecting fixing plate is provided with a shaft core corresponding to the connecting shaft. The connecting bearing is sleeved on the outside of the shaft core to realize the rotation of the control pedal.

[0009] The pressure sensor is installed on the control pedal. The pressure sensor passes through the inside of the groove and is electrically connected to the lifting control board. The pressure sensor converts the pressure signal into an electrical signal and transmits it to the lifting control board so as to accurately control the lifting of the hydraulic telescopic outrigger according to different forces.

[0010] Furthermore, a limiting plate and a trigger block are installed on the movable pulley. The trigger block is fixed on the connecting shaft above the movable pulley. One end of the limiting plate is fixed on the trigger block, and the other end is in contact with the tire of the movable pulley. When the trigger block is pressed, the limiting plate locks the movable pulley, preventing it from rotating.

[0011] Furthermore, a limit ratchet is installed inside the movable pulley. The limit ratchet is sleeved on a roller on one side of the movable pulley and rotates together with the movable pulley. A limit block is installed on the trigger block. The limit block is adapted to the gear of the limit ratchet. The limit block is locked in the gear gap of the limit ratchet to restrict the unidirectional movement of the movable pulley.

[0012] Furthermore, a chassis is installed at the bottom of the roadblock, and corresponding lifting operation holes are provided. The chassis is installed below the hydraulic device for contact with the ground.

[0013] Furthermore, the chassis is equipped with fixing bolts for securing it to the ground.

[0014] Furthermore, the movable lifting roadblock includes the following steps: removing the fixing bolts of the chassis, stepping on the adjusting pedal to control the roadblock body to rise, and extending the lifting outriggers; after the roadblock moves to the designated position, stepping on the adjusting pedal to retract the moving pulley into the roadblock body; the chassis is in contact with the ground, the fixing bolts are installed and tightened to fix the roadblock to the ground.

[0015] This application not only avoids the time-consuming and laborious manual relocation of conventional spherical bollards, greatly improving the flexibility of bollard use; its unique and practical design serves as a warning while allowing for easy relocation of the spherical bollards according to actual needs; the device is easy to operate and can be mastered without complex training, greatly improving work efficiency.

[0025] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application. All other implementations obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application. In the various drawings, the same elements are represented by the same or similar reference numerals, and for clarity, the various parts in the drawings are not drawn to scale.

[0026] See Figure 1-7 As shown, this invention proposes a high-speed closing device with a trigger gap type that allows for long-term flow. It is characterized by comprising: a roadblock body 1, a lifting device 2, and a movable pulley 3. The lifting device 2 is located at the bottom of the roadblock body 1, and the movable pulley 3 is connected below the lifting device 2. When the roadblock needs to be moved, the movable pulley 3 extends out of the roadblock body 1 by adjusting the lifting pedal device, thus enabling flexible movement of the roadblock. In this embodiment, there are multiple lifting devices 2, each with a movable pulley 3 installed below it. Multiple devices 2 are controlled by a single controller. The movable pulley 3 can extend or retract from the roadblock body 1 under the action of the lifting device 2. Preferably, in this embodiment, there are four movable pulleys.

[0027] See Figure 3As shown, specifically, the bottom of the roadblock body 1 has multiple lifting operation holes 11, which are evenly distributed in a ring. The lifting device 2 is installed and fixed inside the lifting operation holes 11. In this embodiment, the bottom of the roadblock body 1 has an installation groove 13, and four lifting operation holes 11 are provided inside the installation groove 13, with each lifting operation hole 11 spaced 90° apart. Specifically, a certain gap is left between the inner wall of the lifting operation hole 11 and the lifting device 2. In the event of an accidental collision, the deformation amplitude is limited within the diameter range of the lifting operation hole 11, preventing serious damage to the overall structure of the roadblock and greatly improving the roadblock's impact resistance and safety. Preferably, an anti-slip cover is installed on the inner wall of the lifting operation hole 11. The anti-slip cover is located between the lifting operation hole 11 and the lifting device 3, serving as an anti-slip and wear-resistant layer, protecting the service life of the device. The chassis 4 is made of high-strength, wear-resistant materials, which can effectively resist ground friction and wear, extend the service life of the roadblock, and reduce the instability of the roadblock caused by chassis wear.

[0028] Specifically, a chassis 4 is installed at the bottom of the roadblock, and a corresponding lifting operation hole 11 is provided. The chassis 4 is installed below the hydraulic device for contact with the ground. Specifically, fixing bolts 41 are installed on the chassis 4 for fixing it to the ground. In this embodiment, the chassis 4 fixes the roadblock body 1 to the ground via the fixing bolts 41, providing stable support.

[0029] See Figure 3 , 4As shown, specifically, the lifting device 2 includes: lifting outriggers 21, a lifting control plate 22, and an adjusting pedal 23. Each lifting operation hole 11 contains a lifting outrigger 21. The lifting control plate 22 is installed at the bottom of the roadblock body 1 and has corresponding lifting operation holes 11. The lifting control plate 22 is connected to each lifting outrigger 21. A synchronization controller 24 is installed on the lifting control plate 22 to control the synchronized lifting and lowering of each lifting outrigger 21. In this embodiment, the synchronization controller 24 precisely regulates the lifting speed and amplitude of each lifting outrigger 21 through a preset program, ensuring synchronization during lifting and lowering and avoiding tilting or swaying of the roadblock body due to uneven lifting and lowering. Specifically, the lower end of the roadblock body 1 has a pedal groove 12 that communicates with the bottom of the roadblock body 1. The pedal groove 12 is located on the surface of the roadblock body 1 and is a certain distance from the bottom of the roadblock body 1. The control pedal 231 is installed in the pedal groove 12 and connected to the lifting control plate 22. The operator sends a lifting command to the lifting control plate 22 by stepping on the adjustment pedal 23, thereby controlling the lifting action of the lifting outrigger 21. The operation is simple and labor-saving.

[0030] See Figure 5 As shown, specifically, the lifting outrigger 21 includes a hydraulic rod 211 and a cylinder 212. The cylinder 212 is sleeved outside the hydraulic rod 211, and the cylinder 212 is sealed to both ends of the hydraulic rod 211. One end of the hydraulic rod 211 is fixed inside the lifting working hole 11, and one end of the cylinder 212 is connected to the movable pulley 3. The lifting outrigger 21 is provided with an oil inlet valve 213 and an oil return valve 214. The oil inlet valve 213 and the oil return valve 214 of each lifting outrigger 21 are connected to the oil pipe of the lifting control board 22. The lifting control board 22 is connected to the oil tank 25 through the oil inlet pipe 251. The oil tank 25 is fixed inside the roadblock body 1. The synchronous controller 24 controls the synchronous lifting of the lifting outrigger 21 by controlling the oil volume of the oil pipe. In this embodiment, the hydraulic rod 211 can extend and retract axially along the cylinder 212. The bottom of the cylinder 212 is provided with a sealing cover 215, and the top of the hydraulic rod 211 is fixedly connected to the bottom of the roadblock body 1 through a flange. The cylinder 212 is provided with an oil inlet valve 213 on its side wall. The oil inlet valve 213 and the oil return valve 214 are both connected to the oil inlet pipe 251 of the lifting control plate 22. The oil pipe 251 extends into the oil tank 25, and the oil tank 25 is fixed on the mounting groove 13 inside the roadblock body 1.

[0031] See Figure 6As shown, specifically, the adjusting pedal 23 includes: a control pedal 231, a pressure sensor 235, and a connecting fixing piece 232. The control pedal 231 is mounted and fixed on the roadblock body 1 via the connecting fixing piece 232. The control pedal 231 is provided with a connecting bearing 233, and the connecting fixing piece 232 is provided with a shaft core 234 corresponding to the connecting bearing 233. The connecting bearing 233 is sleeved on the shaft core 234 to realize the rotation of the adjusting pedal 23. The pressure sensor 235 is installed on the control pedal 231. The pressure sensor 235 passes through the inside of the pedal groove 12 and is electrically connected to the lifting control plate 22. The pressure sensor 235 converts the pressure signal into an electrical signal and transmits it to the lifting control plate 22 so as to accurately control the lifting and lowering of the hydraulic telescopic outrigger according to different forces. In this embodiment, when the user steps on the control pedal 231, the pressure sensor 235 quickly captures the pressure data and immediately converts it into an electrical signal. These electrical signals are transmitted stably and efficiently to the lifting control board 22 through the line. The lifting control board 22 accurately calculates the required lifting height of the hydraulic telescopic outrigger based on the electrical signals corresponding to different forces received, and then issues corresponding control commands to achieve precise lifting of the outrigger.

[0032] See Figure 7As shown, specifically, a limiting piece 31 and a trigger block 32 are installed on the movable pulley 3. The trigger block 32 is fixed on the connecting shaft above the movable pulley 3. One end of the limiting piece 31 is fixed on the trigger block 32, and the other end is in contact with the tire of the movable pulley 3. When the trigger block 32 is pressed, the limiting piece 31 locks the movable pulley 3, preventing it from rotating. Specifically, a limitable ratchet 33 is also installed inside the movable pulley 3. The limitable ratchet 33 is sleeved on a roller 34 on one side of the movable pulley 3 and rotates with the movable pulley 3. A limiting block 321 is installed on the trigger block 32. The limiting block 321 is matched with the gear of the limitable ratchet 33. The limiting block 321 is engaged in the gear gap of the limitable ratchet 33, restricting the unidirectional movement of the movable pulley 3. In this embodiment, when the position of the roadblock needs to be fixed, the operator only needs to press the trigger block 32. The trigger block 32 drives the limiting plate 31 to move, causing the limiting plate 31 to lock the movable pulley 3. At the same time, the limiting block 321 on the trigger block 32 engages in the gear gap of the limitable ratchet 33, so the movable pulley can neither rotate nor move in the opposite direction, thus achieving stable fixation of the roadblock. Operating the trigger block again releases the limitation of the limiting plate and the limiting block on the movable pulley and the limitable ratchet, allowing the movable pulley to resume normal rotation, and the roadblock can be easily moved. Preferably, the limitable ratchet 33, the limiting plate 32, and the trigger block 32 are made of high-strength alloy material and have undergone special processing, possessing extremely high wear resistance and corrosion resistance, enabling long-term stable operation in various harsh environments. This method not only effectively prevents the roadblock from accidentally sliding downhill under pressure but also greatly enhances the overall structural stability and safety.

[0033] The movable lifting roadblock includes the following steps: remove the fixing bolts of the chassis, step on the adjustment pedal to control the roadblock body to rise, and extend the lifting outriggers; after the roadblock moves to the designated position, step on the adjustment pedal to retract the moving pulley into the roadblock body; when the chassis is in contact with the ground, install and tighten the fixing bolts to fix the roadblock to the ground.

[0034] The beneficial effects of this invention are as follows: it not only avoids the time-consuming and laborious manual relocation of conventional spherical bollards, greatly improving the flexibility of bollard use; its unique and practical design not only serves as a warning, but also allows operators to easily move the spherical bollards according to actual needs through a simple stepping motion. The entire operation process requires no complex training; ordinary personnel can master it after a short period of instruction, greatly improving work efficiency; the device is easy to operate and can be mastered without complex training, significantly improving work efficiency.
