Description
Technical Field
[0001] This utility model relates to the technical field of highway greening isolation equipment, specifically a landscape greening isolation belt structure for highway environmental protection. Background Technology
[0002] Landscape green isolation belts for highway environmental protection are mainly used for the isolation and protection of road and site boundaries. Their core function is to provide physical barriers to prevent people, animals or vehicles from crossing at will, ensure traffic safety and regional order, and improve the environmental quality and landscape effect of highways.
[0003] Currently, highway median strip structures generally adopt a modular construction method. During construction, the column foundations must be fixed first, and then the prefabricated columns and other guardrail components such as horizontal bars and vertical bars are precisely aligned and spliced and tightened point by point with bolts. After the components are connected by multiple sets of bolts to form a whole, a continuous protective barrier is finally formed. This method is widely used in engineering due to the standardization of components. However, the installation process requires manual alignment and tightening of each bolt at every connection point, which is complicated and time-consuming. This not only significantly slows down the overall construction progress and extends the construction period, but also significantly increases labor costs due to the large amount of manpower required. Furthermore, in subsequent maintenance, if damaged components need to be disassembled and replaced, the bolts need to be loosened one by one, which is equally cumbersome. This further increases the difficulty and time cost of maintenance and affects the efficiency of road traffic.
[0004] Therefore, this utility model provides a landscape green isolation belt structure for highway environmental protection to solve the problems mentioned above. Utility Model Content
[0005] The purpose of this utility model is to provide a landscape green isolation belt structure for highway environmental protection, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: A landscape green isolation belt structure for highway environmental protection includes columns, a barrier strip installed on one side of the column, a counterweight base installed below the column to enhance the stability of the column and prevent it from tipping over, and a protective cap movably fitted on the top of the column to prevent dust and corrosion and protect the internal structure of the column. The barrier strip consists of horizontal bars and vertical bars. The two ends of the horizontal bars are fixedly connected to the posts through installation components. The installation components can simplify the installation and disassembly process of the barrier strip and improve construction and maintenance efficiency. The posts have adjustable components fixedly installed in their inner cavities, which can flexibly adjust the height of the posts to adapt to different highway scenarios.
[0007] As a further embodiment of this utility model, the installation assembly includes an installation plate and a fixing plate. The installation plate is welded to one end of the crossbar, and the fixing plate is welded to the side wall of the column. An insert block and a fixing block are respectively fixedly installed on the side of the installation plate and the fixing plate that are close to each other, and the inner cavity of the fixing block is provided with a slot for inserting the insert block.
[0008] As a further embodiment of this utility model, the inner cavity of the fixing block is provided with a guide groove and a sliding strip is slidably installed thereon to enhance the locking of the insertion block, and a driving block is fixedly connected to the bottom end of the sliding strip.
[0009] As a further embodiment of this utility model, the adjustment component consists of a movable column, a connecting plate, and a threaded rod. The movable column is slidably installed at the bottom of the inner cavity of the column, and the connecting plate is fixedly installed on the inner wall of the column. A threaded rod is rotatably installed at the center of the connecting plate via a bearing, which is used to drive the column to move up and down.
[0010] As a further embodiment of this utility model, a threaded sleeve is fixedly installed on the inner wall of the movable column, and the threaded sleeve and the threaded rod form a precision threaded engagement. When the threaded rod rotates, the threaded sleeve converts the rotational motion into the linear lifting and lowering of the column, thereby achieving stable and controllable height adjustment.
[0011] As a further embodiment of this utility model, the inner cavity of the horizontal bar is provided with an installation groove, and the vertical bar is inserted into the installation groove. The horizontal bar and the vertical bar are firmly connected by rivets to ensure the connection strength between the horizontal bar and the vertical bar. The outer wall of the vertical bar is fitted with a reflective strip to enhance the nighttime warning effect.
[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. When using this utility model, the installation components can avoid the operation of tightening bolts one by one. With the self-aligning function of the conical insert and slot, the docking can be completed quickly. With the help of the return spring, the limiting block is automatically inserted into the slot to form an automated mechanical lock. Compared with bolt connection, it can more effectively resist the continuous vibration of highway vehicles, avoid the risk of loosening after long-term use, and enhance the stability of the overall structural connection. When disassembling, pressing the drive block can unlock it, realizing the quick installation and disassembly of the barrier strip and the column. It greatly simplifies the construction and maintenance process, shortens the construction period, reduces labor costs, and allows for quick replacement of components, reducing the impact on road traffic.
[0013] 2. When using this utility model, the height of the column can be flexibly adapted and safely adjusted by adjusting the components. By using the cooperation of the movable column, threaded rod and threaded sleeve, the rotational motion can be converted into the vertical lifting and lowering of the column by rotating the knob. It can easily adapt to the isolation requirements of different highway scenarios. No complicated tools are required for operation and the steps are simple. Moreover, the limiting plate at the bottom of the threaded rod can limit the upward end point, prevent the structure from deviating from the effective stroke, ensure the smooth and safe adjustment process, and ensure stable load-bearing.

[0020] 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.
[0021] Please see Figure 1 , Figure 2In this embodiment of the utility model, a landscape green isolation belt structure for highway environmental protection includes a column 1, a barrier strip 2 installed on one side of the column 1, a counterweight base 3 installed below the column 1 to enhance the stability of the column 1 and prevent it from tipping over, and a protective cap 4 movably fitted on the top of the column 1 to prevent dust and corrosion and protect the internal structure of the column 1. The barrier strip 2 consists of a horizontal bar 201 and a vertical bar 202. The two ends of the horizontal bar 201 are fixedly connected to the column 1 through the installation component 5. The installation component 5 can simplify the installation and disassembly process of the barrier strip 2 and improve the construction and maintenance efficiency. The inner cavity of the column 1 is fixedly installed with an adjustment component 6, which can flexibly adjust the height of the column 1 to adapt to the needs of different highway scenarios. It should be noted that the counterweight base 3 is pre-filled with sand and gravel and anchored to the hardened concrete base with expansion bolts, thus forming a dual guarantee of "self-weight anchoring" and "mechanical locking" to ensure the overall structure is stable and can effectively resist impact and overturning. At the same time, the surfaces of the column 1, the barrier strip 2 and the protective cap 4 are all sprayed with protective paint, which can effectively isolate water vapor, acid, alkali and salt and other corrosive media, improve the corrosion resistance and anti-aging ability of each component, thereby extending the overall service life and keeping its appearance clean.
[0022] Please see Figure 2 , Figure 3 , Figure 4 The mounting assembly 5 includes a mounting plate 501 and a fixing plate 502. The mounting plate 501 is welded to one end of the crossbar 201, and the fixing plate 502 is welded to the side wall of the column 1. The mounting plate 501 and the fixing plate 502 are respectively fixedly mounted on the side of the mounting plate 501 and the fixing plate 502, and the fixing block 504 has a slot in its inner cavity for inserting the mounting block 503. It should be noted that both the insert 503 and the slot adopt a tapered design of "small end guiding and large end locking". This structure has a self-centering function when inserted, which can effectively reduce the difficulty of manual alignment and improve assembly efficiency. At the same time, the upper and lower sides of the insert 503 and the inner wall of the slot are provided with inclined guide surfaces. Through the wedge effect, a tight mechanical lock is formed after insertion, which can reduce connection shaking, enhance overall stability, and effectively avoid the risk of loosening caused by vibration, thereby ensuring that the barrier strip 2 is accurately positioned and evenly stressed during installation. The inner cavity of the fixing block 504 is provided with a guide groove and a sliding strip 505 is slidably installed thereon to enhance the locking of the insert block 503. The bottom end of the sliding strip 505 is fixedly connected to the driving block 506. It should be noted that the guide groove is used to guide the vertical movement of the sliding bar 505. A limiting block 507 is fixedly installed on the side of the drive block 506 near the insert block 503. The outer wall of the insert block 503 has a slot, and the limiting block 507 is inserted into the slot. It should also be noted that the drive block 506 and the fixed block 504 are connected by a return spring 508. Under the elastic thrust of the spring, the bottom end of the drive block 506 always protrudes into the fixed block 504, and ensures that the limiting block 507 automatically engages in the slot, forming a stable mechanical lock, effectively resisting vibration and preventing loosening. When the insert 503 is inserted, the sliding bar 505 is pushed by the return spring 508, which drives the limiting block 507 through the fixing block 504 and into the slot of the insert 503, forming a mechanical lock. This ensures that the crossbar 201 is installed firmly and effectively resists loosening caused by vibration and other factors. When disassembling, pressing the drive block 506 upward will push the sliding bar 505 to drive the limiting block 507 out of the slot, thereby releasing the lock and quickly releasing the insert 503. This effectively realizes the quick installation and disassembly between the barrier strip 2 and the column 1, ensuring the reliability of the connection in a vibration environment and facilitating daily maintenance and component replacement.
[0023] Please see Figure 2 , Figure 5 The adjustment component 6 consists of a movable column 601, a connecting plate 602, and a threaded rod 603. The movable column 601 is slidably installed at the bottom of the inner cavity of the column 1. The connecting plate 602 is fixedly installed on the inner wall of the column 1, and the threaded rod 603 is rotatably installed at the center of the connecting plate 602 through a bearing, which is used to drive the column 1 to perform lifting and lowering movements. A screw sleeve 604 is fixedly installed on the inner wall of the movable column 601, and the screw sleeve 604 and the threaded rod 603 form a precision thread engagement. When the threaded rod 603 rotates, the screw sleeve 604 converts the rotational motion into the linear lifting and lowering of the column 1, thereby achieving stable and controllable height adjustment. It should be noted that the bottom end of the movable column 601 is fixedly connected to the counterweight base 3, and the top end of the threaded rod 603 passes through the connecting plate 602 and is fixedly connected to the knob 605, providing the operator with a convenient point for rotation and force application. At the same time, the bottom end of the threaded rod 603 is provided with a limiting plate 606, which can effectively limit the upward end point of the column 1, prevent it from leaving the effective stroke of the thread due to excessive lifting, and ensure system safety. When the height needs to be adjusted, rotate the knob 605, which will cause the threaded rod 603 to rotate accordingly. Since the threaded sleeve 604 is fixed to the moving column 601 and the bottom of the moving column 601 is fixed to the counterweight base 3, its axial movement is constrained. Therefore, the rotational movement of the threaded rod 603 will be converted into the vertical lifting and lowering movement of the column 1 relative to the moving column 601, so as to realize the stable and reliable adjustment of the height of the column 1, ensure operational safety, guarantee load-bearing stability, and simplify the operation steps.
[0024] Please see Figure 2The horizontal bar 201 has an inner cavity with an installation groove, and the vertical bar 202 is inserted into the installation groove. The horizontal bar 201 and the vertical bar 202 are firmly connected by rivets 203 to ensure the connection strength between the horizontal bar 201 and the vertical bar 202. The outer wall of the vertical bar 202 is fitted with reflective strips 204 to enhance the nighttime warning effect. It should be noted that the outer wall of the vertical rod 202 is fixedly fitted with a waterproof gasket 205, and its position is consistent with the top surface of the mounting groove. This can effectively prevent rainwater from seeping into the interior through the gaps in the mounting groove, delay the corrosion of metal components, and extend the overall service life.
[0025] The working principle of this utility model is as follows: When this utility model is used, the counterweight base 3 is first anchored to the hardened concrete base with expansion bolts to provide stable support for the entire barrier strip 2 structure. Then align the mounting plate 501 with the fixing plate 502, push the barrier strip 2 so that the insert 503 is aligned and inserted into the conical slot of the fixing block 504 welded on the column 1, and use the conical surface to achieve self-centering, thus completing the initial positioning of the barrier strip 2. During the insertion of the insert block 503, the reset spring 508 pushes the drive block 506 and the sliding bar 505, so that the limiting block 507 automatically embeds into the slot of the insert block 503, forming an anti-vibration and anti-loosening automatic lock; when disassembly is required, press the drive block 506 upward to overcome the elastic force of the reset spring 508, drive the limiting block 507 out of the slot, and the lock can be released, separating the barrier strip 2 from the column 1; Subsequently, by rotating the knob 605, rotational power is provided, causing the threaded rod 603 to rotate accordingly. The threaded rod 603 engages with the threaded sleeve 604. Since the bottom end of the moving column 601 is fixed to the counterweight base 3, its axial movement is constrained. Therefore, the rotational motion of the threaded rod 603 is converted into the vertical lifting motion of the column 1 relative to the moving column 601. With the help of the limiting plate 606, the column 1 can be prevented from moving too high and disengaging from the effective thread stroke, ensuring safe adjustment. Finally, the protective cap 4 is fastened to the top of the column 1 to prevent water from entering from the top.
[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
