Description

Technical Field

[0001] This utility model relates to the field of traffic safety management technology, and in particular to emergency hydraulic lifting bollards. Background Technology

[0002] Emergency hydraulic bollards are security facilities that achieve rapid raising and lowering through hydraulic drive. They are mainly used to deal with emergencies, ensuring the safety of areas through physical isolation and passage control. Their application scenarios are mainly concentrated in places where temporary and emergency restrictions on vehicle passage are required to ensure the safety of personnel and important facilities.

[0003] In the existing technology, some emergency hydraulic lifting bollards are mainly composed of a bollard body, a hydraulic power system, and a base. The emergency hydraulic lifting bollard is triggered by the control system to make the oil pump drive the hydraulic oil in the cylinder to generate pressure, thereby driving the bollard body to rise and fall, so as to achieve the purpose of quickly blocking and releasing traffic.

[0004] In existing technologies, some emergency hydraulic bollard devices are typically fixed by placing the bollard directly in the soil during use, which makes it difficult to disassemble the hydraulic bollard. This not only increases the workload and time cost for personnel, but also limits the adjustability and flexibility of the device to a certain extent. Therefore, the emergency hydraulic bollard is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an emergency hydraulic lifting bollard, which aims to improve the problem that some hydraulic lifting bollard devices in the prior art are difficult to install and disassemble quickly during use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An emergency hydraulic lifting bollard includes a hydraulic bollard with a support and protection column slidably connected to its bottom. A quick-installation mechanism is provided at the top of the support and protection column, and a stabilizing mechanism is provided at its bottom. The quick-installation mechanism includes a fixing plate, the bottom of which is slidably connected to the top of the support and protection column. Multiple limiting seats are fixedly connected inside the support and protection column. Multiple trapezoidal connecting blocks are fixedly connected to the top of the fixing plate. Multiple limiting posts are fixedly connected inside the fixing plate. Connecting posts are slidably connected inside the trapezoidal connecting blocks. Elastic components are slidably connected inside the limiting posts. A rotating post is fixedly connected to the bottom of the connecting post, and a limiting fixing post is fixedly connected to the bottom of the rotating post. As a further description of the above technical solution: The stabilizing mechanism includes a reinforcing plate, the top of which is fixedly connected to the bottom of the supporting protective column. Multiple stabilizing columns are fixedly connected to the top of the reinforcing plate. Multiple limiting blocks are fixedly connected to the outside of the hydraulic column. A flashing light is fixedly connected to the top of the hydraulic column. As a further description of the above technical solution: The elastic component includes a fixed plate, the outside of which is slidably connected to the inside of the limiting post, and a telescopic spring is slidably connected inside the limiting post. As a further description of the above technical solution: The bottom of the telescopic spring is fixedly connected to the top of the inner side of the limiting post, and the inside of the telescopic spring is sleeved on the outside of the connecting post. As a further description of the above technical solution: The limiting seat has a limiting groove inside, and the limiting fixing post is slidably connected to the inside of the limiting groove. As a further description of the above technical solution: The external parts of the plurality of connecting columns are slidably connected to the inside of the fixed plate, and the top of the connecting columns are slidably connected to the inside of the trapezoidal connecting block; As a further description of the above technical solution: The external sliding connection of the plurality of limiting blocks is made to the inside of the support and protection column, and the top of the hydraulic column is provided with an exhaust hole; As a further description of the above technical solution: The fixed plate is internally slidably connected to the outside of the hydraulic column, and the fixed plate is internally slidably connected to the outside of the flash lamp.

[0007] This utility model has the following beneficial effects: 1. In this utility model, the hydraulic column is connected to the fixed plate through a trapezoidal connecting block. Pressing the connecting column causes the fixed plate to move downward, compressing the spring and driving the rotating column downward, so that the limiting fixing column enters the limiting seat to achieve limiting fixation. Rotating the connecting column causes the rotating column to reverse, so that the limiting fixing column coincides with the limiting groove, completing the disassembly. This improves the efficiency of installation and disassembly, facilitates the installation of the hydraulic column while protecting it, reduces costs and saves time.

[0008] 2. In this utility model, the hydraulic column is fixed below the ground by the reinforcing plate and the stabilizing column, which ensures the stability of the hydraulic column during use and makes the supporting protection column fixed below the ground, thereby improving the stability of the equipment. When the hydraulic column comes into contact with the ground, it will stop automatically. The limiting block further reinforces the connection between the hydraulic column and the supporting protection column, ensuring a more secure installation. The flashing light provides the user with a clearer visual indication, enhancing the safety and convenience of operation. Attached Figure Description

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] Example: Emergency hydraulic lifting bollard, refer to Figures 1 to 3The system includes a hydraulic column 1, which is the core actuator of the emergency hydraulic lifting column. It uses its extension and retraction to block or allow passage in a specific area. A support and protection column 2 is slidably connected to the bottom of the hydraulic column 1, providing support and protection for the hydraulic column 1. A quick-installation mechanism 3 is located at the top of the support and protection column 2. The quick-installation mechanism 3 includes a fixing plate 31, which connects the hydraulic column 1 and the support and protection column 2, stably fixing the hydraulic column 1 to the top of the support and protection column 2, enhancing the overall structural stability. The bottom of the fixing plate 31 is slidably connected to the top of the support and protection column 2. Multiple limiting seats 35 are fixedly connected inside the support and protection column 2, and these limiting seats 35 are connected to the limiting and fixing columns 3. 8. The connecting column 34 and the fixing plate 31 are fixedly connected. The top of the fixing plate 31 is fixedly connected with multiple trapezoidal connecting blocks 32. The trapezoidal connecting blocks 32 increase the contact area and connection stability between the fixing plate 31 and the connecting column 34, and provide a channel for the installation and sliding of the connecting column 34. The inside of the fixing plate 31 is fixedly connected with multiple limiting columns 33. The limiting columns 33 play a limiting and guiding role for the elastic component 39 and the connecting column 34. The connecting column 34 is slidably connected inside the trapezoidal connecting block 32. The connecting column 34 connects the limiting fixing column 38 and the elastic component 39, and transmits the force to realize the connection and separation of the fixing plate 31 and the support protection column 2. The elastic component 39 is slidably connected inside the limiting column 33. Specifically, when it is necessary to install the hydraulic column 1 and the support and protection column 2, the quick installation mechanism 3 is used to place the fixing plate 31 on the top of the support and protection column 2, so that the trapezoidal connecting block 32 contacts the corresponding position on the top of the support and protection column 2. The connecting column 34 is pushed so that it slides inside the trapezoidal connecting block 32. The connecting column 34 drives the elastic component 39 to slide inside the limiting column 33. The elastic component 39 is compressed. When the connecting column 34 moves to the corresponding position, the limiting fixing column 38 aligns with the limiting seat 35 inside the support and protection column 2. The elastic component 39 is reset, pushing the connecting column 34 and the limiting fixing column 38 to move. The limiting fixing column 38 is inserted into the limiting seat 35, completing the fixing of the hydraulic column 1 and the support and protection column 2. When separation is required, an external force is applied to make the connecting column 34 slide in the opposite direction, compressing the elastic component 39. The limiting fixing column 38 is disengaged from the limiting seat 35, and the hydraulic column 1 can be removed from the support and protection column 2. Afterwards, the hydraulic column 1 can block and release specific areas through its own extension and retraction.

[0013] The elastic component 39 includes a fixed disk 391, which transmits the elastic force of the telescopic spring 392 to the connecting post 34, and simultaneously limits and guides the movement of the connecting post 34. The fixed disk 391 is externally slidably connected to the inside of the limiting post 33, and the telescopic spring 392 is slidably connected inside the limiting post 33. The telescopic spring 392 enables the connecting post 34 and the limiting fixed post 38 to automatically reset during installation and disassembly. The bottom of the telescopic spring 392 is fixedly connected to the top inner side of the limiting post 33, and the inside of the telescopic spring 392 is sleeved on the outside of the connecting post 34. The bottom of the connecting post 34 is fixedly connected to a rotating post 36, which connects the connecting post 34 and the limiting fixed post 38, transmitting the rotation of the connecting post 34 to the limiting fixed post 38, thereby enabling the limiting fixed post 38 to move within the limiting seat 35. The rotation within allows the limiting and fixing column 38 to smoothly cooperate with the limiting seat 35 to achieve fixation and separation, ensuring the normal function of the quick installation mechanism 3. The bottom of the rotating column 36 is fixedly connected to the limiting and fixing column 38. The limiting seat 35 has a limiting groove 37 inside, which provides a channel for the limiting and fixing column 38 to enter the limiting seat 35. At the same time, after the limiting and fixing column 38 rotates, it cooperates with the limiting seat 35 to achieve its limitation. The outside of the limiting and fixing column 38 is slidably connected to the inside of the limiting groove 37. The limiting and fixing column 38 realizes the quick fixation and separation between the fixing plate 31 and the support and protection column 2. The outside of the multiple connecting columns 34 is slidably connected to the inside of the fixing plate 31. The top of the connecting column 34 is slidably connected to the inside of the trapezoidal connecting block 32. The bottom of the support and protection column 2 is provided with a stabilizing mechanism 4. Specifically, during operation, an external force is applied to the connecting column 34, causing it to slide the fixed plate 391 along the inside of the limiting column 33, compressing the telescopic spring 392. Simultaneously, as the connecting column 34 moves, the bottom rotating column 36 drives the limiting fixed column 38 to move synchronously, allowing the limiting fixed column 38 to enter the limiting groove 37 of the limiting seat 35. Then, the connecting column 34 is rotated, and the rotating column 36 transmits the rotation to the limiting fixed column 38, causing it to rotate within the limiting seat 35 until it is misaligned with the limiting groove 37, thus completing the fixing. During disassembly, the connecting column 34 is rotated in the opposite direction, causing the limiting fixed column 38 to return to its position corresponding to the limiting groove 37. The telescopic spring 392 releases its elasticity, pushing the fixed plate 391 back to its original position, and causing the connecting column 34 and the limiting fixed column 38 to move out of the limiting seat 35 along the limiting groove 37.

[0014] Reference Figure 1 and Figure 4The stabilizing mechanism 4 includes a reinforcing plate 41, which increases the contact area between the stabilizing mechanism 4 and the ground soil. The top of the reinforcing plate 41 is fixedly connected to the bottom of the supporting protective column 2. Multiple stabilizing columns 42 are fixedly connected to the top of the reinforcing plate 41, extending deep into the ground to further enhance the anchoring force of the stabilizing mechanism 4. Together with the reinforcing plate 41, they improve the stability of the entire device. Multiple limiting blocks 43 are fixedly connected to the outside of the hydraulic column 1. The limiting blocks 43 restrict the sliding range of the hydraulic column 1 within the supporting protective column 2, while simultaneously enhancing the tightness of the connection between the hydraulic column 1 and the supporting protective column 2. A flashlight 45 is fixedly connected to the top of column 1. Multiple limit blocks 43 are externally slidably connected to the inside of the support and protection column 2. An exhaust hole 44 is opened on the top of the hydraulic column 1. The exhaust hole 44 discharges the air in the closed space between the top of the hydraulic column 1 and the fixed plate 31, so as to avoid the obstruction of the lifting and lowering of the hydraulic column 1 due to air compression and expansion. The inside of the fixed plate 31 is slidably connected to the outside of the hydraulic column 1. The inside of the fixed plate 31 is slidably connected to the outside of the flashlight 45. In an emergency, it emits a conspicuous flash signal to remind the surrounding personnel and vehicles to pay attention to the status of the hydraulic column 1, which serves as a warning. Specifically, the hydraulic column 1 slides within the support and protection column 2, and multiple limit blocks 43 move synchronously with the hydraulic column 1 to limit its sliding range. When the hydraulic column 1 is raised or lowered, the exhaust port 44 discharges the air in the enclosed space between its top and the fixed plate 31. The fixed plate 31 slides outside the hydraulic column 1 and the flashing light 45. In the stabilizing mechanism 4, the reinforcing plate 41 plays a role by increasing the contact area with the ground soil. Multiple stabilizing columns 42 extend into the ground and work together with the reinforcing plate 41. In an emergency, the flashing light 45 emits a flashing signal.

[0015] The implementation principle of this application embodiment is as follows: First, during use, the support and protection column 2 is installed on the ground, while the hydraulic column 1 is placed inside the support and protection column 2, and the fixing plate 31 is placed on top of the support and protection column 2. When installing and fixing the hydraulic column 1, the trapezoidal connecting block 32 is placed on top of the fixing plate 31. Simultaneously, pressing the connecting column 34 causes the fixing plate 391 to move downwards, and the telescopic spring 392 is compressed, thereby causing the rotating column 36 to move downwards, thus limiting... The positioning and fixing post 38 enters the interior of the limiting seat 35 through the limiting groove 37. When the rotating connecting post 34 drives the rotating post 36 to rotate inside the limiting seat 35, the positioning and fixing post 38 is fixed inside the limiting seat 35, thus enabling the hydraulic post 1 to be installed quickly. At the same time, when the connecting post 34 is reversed and the positioning and fixing post 38 overlaps with the limiting groove 37, the telescopic spring 392 drives the connecting post 34 and the positioning and fixing post 38 to move upward, thus enabling the fixing plate 31 and the support and protection post 2 to be disassembled quickly.

[0016] Secondly, during use, the reinforcing plate 41 and the stabilizing column 42 are fixed underground, as are the supporting and protective columns 2, thereby maintaining the stability of the hydraulic column 1 during use and ensuring that the supporting and protective columns 2 are fixed below the ground. When the hydraulic column 1 coincides with the ground, the hydraulic column 1 stops. The limiting block 43 makes the installation of the hydraulic column 1 and the supporting and protective columns 2 more secure, and it is also fixed by the fixing plate 31. The use of the flashlight 45 can provide the user with more visible observation.

[0017] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
