Excess protective netting is wound into the storage cavity, thus improving the flexibility of the guardrail's use.

Description

Technical Field

[0001] This invention belongs to the field of guardrail technology, and in particular relates to an ecological three-dimensional guardrail. Background Technology

[0002] The ecological environment refers to the total quantity and quality of water resources, land resources, biological resources, and climate resources that affect human survival and development. It is a complex ecosystem related to the sustainable development of society and the economy. Ecological and environmental problems refer to the various negative feedback effects that endanger human survival caused by the destruction and pollution of the natural environment in the process of human beings utilizing and transforming nature for their own survival and development.

[0003] The national goal of ecological and environmental protection is to curb ecological damage, mitigate the harm of natural disasters, promote the rational and scientific use of natural resources, achieve a virtuous cycle of natural ecosystems, and safeguard ecological and environmental security. When protecting the ecological environment, it is often necessary to use guardrails to separate ecological protection zones from roads, thereby protecting the ecological environment.

[0004] To improve the installation efficiency of guardrails, the current practice is to weld and process the guardrails in the factory and then transport them to the site for assembly. However, prefabricated guardrails are generally very long, which makes them inconvenient to handle and store during transportation. In addition, the dimensions of prefabricated guardrails are fixed and cannot be adjusted according to site requirements, resulting in poor practicality. Summary of the Invention

[0005] The purpose of this invention is to provide an ecological three-dimensional guardrail, which aims to solve the problem that existing guardrails are large in size and inconvenient to transport and handle.

[0006] This invention is implemented as follows: an ecological three-dimensional guardrail includes posts, a protective net, a winding shaft, and a linkage support assembly. Two posts are provided, each with a storage cavity and a rectangular clearance opening for the protective net to enter and exit. A winding shaft is rotatably connected to each of the two storage cavities, and both ends of the protective net are fixed to the two winding shafts respectively. A driving component is provided on the winding shaft to drive its rotation. Two pairs of linkage support assemblies are provided, arranged vertically on the posts, with each pair of two linkage support assemblies positioned on both sides of the protective net. These linkage support assemblies support and reinforce the protective net.

[0007] In a further technical solution, a mounting base is fixed on the column, and the mounting base is provided with mounting holes.

[0008] A further technical solution includes a first mounting base, a first rotating shaft, a first connecting rod, a second connecting rod, a third connecting rod, a first pin, a second mounting base, a second rotating shaft, a fourth connecting rod, a fifth connecting rod, a sixth connecting rod, and a second pin. Each of the two columns is equipped with a first mounting base, and each of the two first mounting bases is rotatably connected to a first rotating shaft. Each of the two first rotating shafts is fixed with a first connecting rod. The ends of each of the two first connecting rods are rotatably connected to a second connecting rod via a first pin. The ends of each of the two second connecting rods are rotatably connected to a second connecting rod via a first pin. The three-bar linkage consists of two third-bar linkages rotatably connected by a first pin. Each of the two columns is equipped with a second mounting base. Each of the two second mounting bases is rotatably connected to a second rotating shaft. Each of the two second rotating shafts is fixed with a fourth-bar linkage. The ends of each of the two fourth-bar linkages are rotatably connected to a fifth-bar linkage via a second pin. The ends of each of the two fifth-bar linkages are rotatably connected to a sixth-bar linkage via a second pin. The two sixth-bar linkages are rotatably connected by a second pin. The middle sections of the second and fifth-bar linkages are rotatably connected, as are the middle sections of the third and sixth-bar linkages.

[0009] In a further technical solution, gears are fixed on both the first and second rotating shafts.

[0010] A further technical solution is that a reinforcing frame is rotatably connected to the first pin, the protective net passes through the reinforcing frame, the reinforcing frame is provided with protrusions, and the reinforcing frame is provided with notches for avoiding the protective net.

[0011] In a further technical solution, the reinforcing frame is provided with a clamping assembly, which fixes the protective netting to the reinforcing frame by means of the extension of the connecting rod support assembly.

[0012] In a further technical solution, the clamping assembly includes a clamping block and a tension spring. The reinforcing frame is provided with an elongated hole, and the second pin extends into the elongated hole. The reinforcing frame is provided with a first sliding groove, and the clamping block is slidably connected in the first sliding groove. The two ends of the tension spring are respectively connected to the clamping block and the inner wall of the first sliding groove. The reinforcing frame is provided with a transmission assembly, and the transmission assembly drives the clamping block to move by moving the second pin in the elongated hole.

[0013] In a further technical solution, the transmission assembly includes a pull rope, a push block, and a fixing block. The reinforcing frame is provided with an L-shaped groove. The push block and the fixing block are both disposed in the L-shaped groove. The push block is slidably connected to the L-shaped groove. The fixing block is fixed to the push block. The two ends of the pull rope are respectively connected to the push block and the second pin. The push block is slidably engaged with the clamping block. The contact surface between the push block and the clamping block is an inclined surface.

[0014] In a further technical solution, the driving component is a motor, which is fixed on the column, and the rotating end of the motor is connected to the winding shaft.

[0015] In a further technical solution, the driving component is a handwheel, which is fixed to the end of the take-up shaft and has anti-slip texture.

[0016] This invention provides an ecological three-dimensional guardrail. During transport, a drive unit rotates a winding shaft to wind up the protective netting. As the netting winds up, the connecting rod support assembly also retracts, thus storing the netting within a storage cavity, reducing the guardrail's volume and facilitating transport and handling. When installing the guardrail, pulling the two uprights in the opposite direction pulls the netting out of the storage cavity, increasing the guardrail's length. The connecting rod support assembly also extends with the movement of the two uprights. The length of the guardrail can be adjusted according to actual usage needs by changing the distance between the two uprights. Excess netting is stored within the storage cavity, improving the guardrail's flexibility. The connecting rod support assemblies on both sides of the netting limit its movement, thereby increasing the netting's strength and enhancing the guardrail's stability. Attached Figure Description

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0028] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0029] Example 1, as Figures 1-4 As shown, an ecological three-dimensional guardrail according to an embodiment of the present invention includes posts 101, and further includes: a protective net 103, a winding shaft 105, and a connecting rod support assembly 6; two posts 101 are provided, each post 101 is provided with a storage cavity 104, and the storage cavity 104 is provided with a rectangular clearance opening 107 for the entry and exit of the protective net 103; the winding shaft 105 is rotatably connected to the two storage cavities 104, and the two ends of the protective net 103 are respectively fixed to the two winding shafts 105; a driving member is provided on the winding shaft 105, and the driving member is used to drive the winding shaft 105 to rotate; two pairs of connecting rod support assemblies 6 are provided, and the two pairs of connecting rod support assemblies 6 are arranged vertically on the posts 101, with each pair of two connecting rod support assemblies 6 respectively arranged on both sides of the protective net 103, and the connecting rod support assemblies 6 are used to support and reinforce the protective net 103.

[0030] In this embodiment of the invention, when transporting the guardrail, the motor drives the winding shaft 105 to rotate, and the winding shaft 105 winds up the protective netting 103. As the protective netting 103 winds up, the connecting rod support assembly 6 also retracts, thereby winding the protective netting 103 into the storage cavity 104, thus reducing the volume of the guardrail and facilitating transportation and handling. When installing the guardrail, the two uprights 101 are pulled in the opposite direction, thereby pulling the protective netting 103 out of the storage cavity 104, thereby increasing the length of the guardrail. The connecting rod support assembly 6 also extends with the movement of the two uprights 101. The length of the guardrail can be adjusted according to the actual usage requirements by adjusting the distance between the two uprights 101. The excess protective netting 103 is wound into the storage cavity 104, thereby improving the flexibility of the guardrail. The connecting rod support assemblies 6 located on both sides of the protective netting 103 limit the protective netting 103, thereby improving the strength of the protective netting 103 and improving the stability of the guardrail.

[0031] Example 2, as Figures 1-5 As shown, an ecological three-dimensional guardrail according to an embodiment of the present invention includes posts 101, and further includes: a protective net 103, a winding shaft 105, and a connecting rod support assembly 6; two posts 101 are provided, each post 101 is provided with a storage cavity 104, and the storage cavity 104 is provided with a rectangular clearance opening 107 for the entry and exit of the protective net 103; the winding shaft 105 is rotatably connected to the two storage cavities 104, and the two ends of the protective net 103 are respectively fixed to the two winding shafts 105; a driving member is provided on the winding shaft 105, and the driving member is used to drive the winding shaft 105 to rotate; two pairs of connecting rod support assemblies 6 are provided, the two pairs of connecting rod support assemblies 6 are arranged vertically on the posts 101, and the two connecting rod support assemblies 6 in each pair are respectively arranged on both sides of the protective net 103, and the connecting rod support assemblies 6 are used to support and reinforce the protective net 103;

[0032] A mounting base 102 is fixed on the column 101, and the mounting base 102 is provided with mounting holes; the driving component is a motor, which is fixed on the column 101, and the rotating end of the motor is connected to the take-up shaft 105.

[0033] The linkage support assembly 6 includes a first mounting base 601, a first rotating shaft 602, a first connecting rod 603, a second connecting rod 604, a third connecting rod 605, a first pin 606, a second mounting base 607, a second rotating shaft 608, a fourth connecting rod 609, a fifth connecting rod 610, a sixth connecting rod 611, and a second pin 612. A first mounting base 601 is mounted on each of the two columns 101. A first rotating shaft 602 is rotatably connected to each of the two first mounting bases 601. A first connecting rod 603 is fixed to each of the two first rotating shafts 602. The ends of the two first connecting rods 603 are rotatably connected to the second connecting rods 604 via the first pin 606. The ends of the two second connecting rods 604 are rotatably connected to the third connecting rods 605 via the first pin 606. 605 is rotatably connected via a first pin 606. A second mounting base 607 is installed on each of the two columns 101. A second rotating shaft 608 is rotatably connected to each of the two second mounting bases 607. A fourth connecting rod 609 is fixed to each of the two second rotating shafts 608. A fifth connecting rod 610 is rotatably connected to the end of each of the two fourth connecting rods 609 via a second pin 612. A sixth connecting rod 611 is rotatably connected to the end of each of the two fifth connecting rods 610 via a second pin 612. The two sixth connecting rods 611 are rotatably connected via a second pin 612. The middle parts of the second connecting rod 604 and the fifth connecting rod 610 are rotatably connected. The middle parts of the third connecting rod 605 and the sixth connecting rod 611 are rotatably connected. Gears 2 are fixed to both the first rotating shaft 602 and the second rotating shaft 608.

[0034] In this embodiment of the invention, when transporting the guardrail, rotating the handwheel 106 drives the winding shaft 105 to rotate, and the winding shaft 105 winds up the protective net 103. As the protective net 103 winds up, the first connecting rod 603, the second connecting rod 604, the third connecting rod 605, the second mounting base 607, the second rotating shaft 608, the fourth connecting rod 609, the fifth connecting rod 610, and the sixth connecting rod 611 also rotate, thereby causing the connecting rod support assembly 6 to retract, thus... The protective netting 103 is rolled up inside the storage cavity 104, thereby reducing the volume of the fence and facilitating transportation and handling. When installing the fence, the two uprights 101 are pulled in the opposite direction, which pulls the protective netting 103 out of the storage cavity 104, thereby increasing the length of the fence. Furthermore, the first connecting rod 603, the second connecting rod 604, the third connecting rod 605, the second mounting base 607, the second rotating shaft 608, the fourth connecting rod 609, the fifth connecting rod 610, and the sixth connecting rod 611 are reversed... The rotation causes the connecting rod support assembly 6 to extend along with the movement of the two columns 101. When the first connecting rod 603 and the fourth connecting rod 609 rotate, they drive the first rotating shaft 602 and the second rotating shaft 608 to rotate. The first rotating shaft 602 and the second rotating shaft 608 drive the two gears 2 to rotate. Since the two gears 2 are meshed, the rotation directions of the first rotating shaft 602 and the second rotating shaft 608 are opposite and the rotation angles are the same, so that the connecting rod support assembly 6 can only extend and retract in the horizontal direction, preventing the connecting rod support assembly 6 from bending downward and improving the stability of the connecting rod support assembly 6 in limiting the protective net 103. The length of the guardrail can be adjusted according to the actual use needs to increase the distance between the two columns 101. The excess protective net 103 is rolled up in the storage cavity 104, thereby improving the flexibility of the guardrail. The connecting rod support assemblies 6 located on both sides of the protective net 103 limit the protective net 103, thereby increasing the strength of the protective net 103 and improving the stability of the guardrail.

[0035] Example 3, as Figure 1 As shown, an ecological three-dimensional guardrail according to an embodiment of the present invention includes posts 101, and further includes: a protective net 103, a winding shaft 105, and a connecting rod support assembly 6; two posts 101 are provided, each post 101 is provided with a storage cavity 104, and the storage cavity 104 is provided with a rectangular clearance opening 107 for the entry and exit of the protective net 103; the winding shaft 105 is rotatably connected to the two storage cavities 104, and the two ends of the protective net 103 are respectively fixed to the two winding shafts 105; a driving member is provided on the winding shaft 105, and the driving member is used to drive the winding shaft 105 to rotate; two pairs of connecting rod support assemblies 6 are provided, the two pairs of connecting rod support assemblies 6 are arranged vertically on the posts 101, and the two connecting rod support assemblies 6 in each pair are respectively arranged on both sides of the protective net 103, and the connecting rod support assemblies 6 are used to support and reinforce the protective net 103;

[0036] A mounting base 102 is fixed on the column 101, and the mounting base 102 is provided with mounting holes; the driving component is a handwheel 106, which is fixed to the end of the winding shaft 105, and the handwheel 106 is provided with anti-slip texture.

[0037] The linkage support assembly 6 includes a first mounting base 601, a first rotating shaft 602, a first connecting rod 603, a second connecting rod 604, a third connecting rod 605, a first pin 606, a second mounting base 607, a second rotating shaft 608, a fourth connecting rod 609, a fifth connecting rod 610, a sixth connecting rod 611, and a second pin 612. A first mounting base 601 is mounted on each of the two columns 101. A first rotating shaft 602 is rotatably connected to each of the two first mounting bases 601. A first connecting rod 603 is fixed to each of the two first rotating shafts 602. The ends of the two first connecting rods 603 are rotatably connected to the second connecting rods 604 via the first pin 606. The ends of the two second connecting rods 604 are rotatably connected to the third connecting rods 605 via the first pin 606. 605 is rotatably connected via a first pin 606. A second mounting base 607 is mounted on each of the two columns 101. A second rotating shaft 608 is rotatably connected to each of the two second mounting bases 607. A fourth connecting rod 609 is fixed to each of the two second rotating shafts 608. A fifth connecting rod 610 is rotatably connected to the end of each of the two fourth connecting rods 609 via a second pin 612. A sixth connecting rod 611 is rotatably connected to the end of each of the two fifth connecting rods 610 via a second pin 612. The two sixth connecting rods 611 are rotatably connected via a second pin 612. The middle portions of the second connecting rod 604 and the fifth connecting rod 610 are rotatably connected. The middle portions of the third connecting rod 605 and the sixth connecting rod 611 are rotatably connected. Gears 2 are fixed to both the first rotating shaft 602 and the second rotating shaft 608.

[0038] A reinforcing frame 301 is rotatably connected to the first pin 606. The protective net 103 passes through the reinforcing frame 301. The reinforcing frame 301 is provided with a protrusion 302 and a notch 303 for avoiding the protective net 103.

[0039] In this embodiment of the invention, when transporting the guardrail, the handwheel 106 is turned, which drives the winding shaft 105 to rotate. The winding shaft 105 winds up the protective netting 103. As the protective netting 103 winds up, the first connecting rod 603, the second connecting rod 604, the third connecting rod 605, the second mounting base 607, the second rotating shaft 608, the fourth connecting rod 609, the fifth connecting rod 610, and the sixth connecting rod 611 also rotate, thereby causing the connecting rod support assembly 6 to retract, thus winding the protective netting 103 into the storage cavity 104, thereby reducing the volume of the guardrail. For ease of transportation and handling, when installing the guardrail, pulling the two posts 101 in the opposite direction pulls the protective net 103 out of the storage cavity 104, thereby increasing the length of the guardrail. Furthermore, the first link 603, second link 604, third link 605, second mounting base 607, second rotating shaft 608, fourth link 609, fifth link 610, and sixth link 611 rotate in opposite directions, causing the link support assembly 6 to extend along with the movement of the two posts 101. When the first link 603 and fourth link 609 rotate, they drive the first... Rotating shaft 602 and second rotating shaft 608 rotate, driving two gears 2 to rotate. Due to the meshing of the two gears 2, the rotation directions of the first rotating shaft 602 and second rotating shaft 608 are opposite, but their rotation angles are the same. This ensures that the connecting rod support assembly 6 can only extend and retract in the horizontal direction, preventing it from bending downwards and improving the stability of the connecting rod support assembly 6 in limiting the protective net 103. Furthermore, by setting the reinforcing frame 301 and the protrusion 302, the vertical direction of the protective net 103 is limited, thereby further improving... The strength of the protective net 103 is enhanced by the fact that when the protective net 103 is rolled up, the two pairs of first pins 606 will drive the reinforcing frame 301 to move upward. The notch 303 at the lower end of the reinforcing frame 301 avoids the protective net 103. The length of the guardrail can be adjusted according to the actual usage needs by adjusting the distance between the two posts 101. The excess protective net 103 is rolled up in the storage cavity 104, thereby improving the flexibility of the guardrail. The connecting rod support assembly 6 located on both sides of the protective net 103 limits the protective net 103, thereby improving the strength of the protective net 103 and the stability of the guardrail.

[0043] A reinforcing frame 301 is rotatably connected to the first pin 606. The protective net 103 passes through the reinforcing frame 301. A protrusion 302 is provided on the reinforcing frame 301. A notch 303 for avoiding the protective net 103 is provided on the reinforcing frame 301.

[0044] The reinforcing frame 301 is equipped with a clamping assembly 4, which fixes the protective net 103 to the reinforcing frame 301 by extending the connecting rod support assembly 6. The clamping assembly 4 includes a clamping block 403 and a tension spring 404. The reinforcing frame 301 is provided with an elongated hole 401, into which the second pin 612 extends.

[0045] In this embodiment of the invention, when transporting the guardrail, the handwheel 106 is turned, which drives the winding shaft 105 to rotate. The winding shaft 105 winds up the protective netting 103.

When installing the guardrail, the two uprights 101 are pulled in the opposite direction. Then, the protective net 103 is pulled out from the storage cavity 104, thereby increasing the length of the guardrail. The first connecting rod 603, the second connecting rod 604, the third connecting rod 605, the second mounting base 607, the second rotating shaft 608, the fourth connecting rod 609, the fifth connecting rod 610, and the sixth connecting rod 611 rotate in opposite directions, causing the connecting rod support assembly 6 to extend along with the movement of the two columns 101. When the first connecting rod 603 and the fourth connecting rod 609 rotate, they drive the first rotating shaft 602 and the second rotating shaft 608 to rotate. The first rotating shaft 602 and the second rotating shaft 608 drive the two gears 2 to rotate. Due to the meshing of the two gears 2, the first rotating shaft 60... 2. The rotation direction of the second rotating shaft 608 is opposite and the rotation angle is the same, so that the connecting rod support assembly 6 can only extend and retract in the horizontal direction, preventing the connecting rod support assembly 6 from bending downward and improving the stability of the connecting rod support assembly 6 in limiting the protective net 103. By setting the reinforcing frame 301 and the protrusion 302, the vertical direction of the protective net 103 is limited, thereby further improving the strength of the protective net 103. When the protective net 103 is released, the two pairs of second pins 612 will move upward relative to the reinforcing frame 301. At this time, the second pins 612 move upward in the elongated hole 401. The second pins 612 pull the pull rope 501, the pull rope 501 pulls the fixing block 504, and the fixing block... 504 drives the push block 503 to move. The push block 503 overcomes the elastic force of the tension spring 404 through the inclined plane and drives the clamping block 403 to move towards the protective net 103, thereby clamping the protective net 103. This fixes the reinforcing frame 301 to the protective net 103, further improving the strength of the protective net 103. The length of the guardrail can be adjusted according to the actual usage needs, and the distance between the two posts 101 can be adjusted. Excess protective net 103 is rolled up in the storage cavity 104, thereby improving the flexibility of the guardrail. The connecting rod support assembly 6 located on both sides of the protective net 103 limits the protective net 103, thereby improving the strength of the protective net 103 and the stability of the guardrail.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
