Technical Field

[0001] This utility model relates to the field of traffic guardrails, and in particular to a guardrail for traffic engineering. Background Technology

[0002] Traffic engineering is a branch of transportation engineering, which includes five aspects: road transportation, rail transportation, air transportation, water transportation, and pipeline transportation. Road traffic engineering focuses on road traffic, specifically public roads where cars, bicycles, rickshaws, horses, and pedestrians can travel, although restrictions vary depending on the road. Traffic barriers are an essential component in the construction of traffic engineering projects. They separate motorized vehicles, non-motorized vehicles, and pedestrians, longitudinally dividing the road cross-section to ensure separate lanes for each type of vehicle, thereby improving road safety and traffic order.

[0003] Most existing traffic barriers consist of a set of main barriers and several poles that are fixedly connected together. The overall structure is relatively stable, but the barrier height is low and the upper guardrails are relatively smooth. This makes pedestrians feel that there is no danger in climbing over the barriers. In order to save time, they may climb over the barriers, thereby violating traffic rules and potentially causing harm to pedestrians. Utility Model Content

[0004] To address the above shortcomings, this utility model provides a guardrail for traffic engineering, which aims to make pedestrians feel that it is dangerous to climb over the guardrail, thereby improving the problem of pedestrians climbing over the guardrail.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a guardrail for traffic engineering, comprising a post and a vertical bar. First support blocks are slidably connected to both the left and right sides of the post. A connecting block is slidably connected to the top of each first support block. A first bolt is slidably connected to the top of each connecting block. A fixing rod is fixedly connected inside the post. A spring is provided at the bottom end of each first support block. A lower crossbeam is fixedly connected to the bottom end of each vertical bar. A short rod is slidably connected to the inner wall of each vertical bar. A gear shaft is provided on the inner wall of the vertical bar. A small gear is rotatably connected to the outer wall of the gear shaft. Racks are meshed on both the left and right sides of the small gear. A slider is fixedly connected to the opposite side of the rack. A baffle is fixedly connected to the outer wall of one of the sliders. An upper crossbeam is fixedly connected to the top of the baffle. A second bolt is slidably connected to the top of the upper crossbeam. The post is provided with a support and fixing assembly.

[0006] Preferably, the support and fixing assembly includes a second support block, which passes through the connecting block and is threaded to the inner wall of the nut. A fixing block is slidably connected to the inner wall of the second support block. A plurality of fixing blocks are fixedly connected to the left and right sides of the column. The first bolt passes through the connecting block and is threaded to the inner wall of the first support block.

[0007] Preferably, the second bolt passes through the connecting block and is threaded to the bottom end of the upper crossbeam, and the second bolt passes through the connecting block and is threaded to the bottom end of the lower crossbeam.

[0008] Preferably, the rack is slidably connected to the inner wall of the vertical rod, and the vertical rod has a first sliding groove on both the left and right sides, and the slider is slidably connected to the inner wall of the first sliding groove.

[0009] Preferably, a third sliding groove is provided on the right side of the short rod, the rack is slidably connected to the inner wall of the third sliding groove, and the short rod is slidably connected to the outer wall of the pinion.

[0010] Preferably, the vertical rod is slidably connected to the inner wall of the upper crossbeam, the vertical rod is slidably connected to the adjacent side of the two baffles, and the baffles are slidably connected to the outer side of the first slide groove.

[0011] Preferably, the column has multiple second sliding grooves inside, the first support block is slidably connected to the inner wall of the second sliding groove, the spring is slidably connected to the outer wall of the fixing rod, the first support block is slidably connected to the outer wall of the fixing rod, and the spring is disposed at the bottom end of the second sliding groove.

[0012] Preferably, the second support block is slidably connected to the outer wall of the column, and a third bolt is slidably connected to the outer wall of the second support block. The third bolt passes through the second support block and is threaded into the interior of the fixing block.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the meshing between the pinion and the rack applies downward pressure to the upper crossbeam, driving the first support block, the baffle, and the right rack. At the same time, the pinion rotates, causing the left rack to drive the short rod. The first support block moves downward to compress the spring. After the pressure on the upper crossbeam is released, the spring pushes the first support block upward, driving the upper crossbeam. This indirectly causes the pinion to rotate, causing the left rack to drive the short rod downward. This makes pedestrians feel that it is dangerous to climb over the guardrail, thus achieving the effect of preventing pedestrians from climbing over the guardrail.

[0015] 2. In this utility model, the second support block and the fixing block are fixed by threaded connection, so that the second support block passes through the connecting blocks on both sides of the lower crossbeam to support the entire guardrail. At the same time, the upper crossbeam is moved so that the connecting blocks on both sides are moved to the top surface of the first support block, so that the first bolt passes through the connecting block and threadedly connects to the first support block. Then, the second support block is threadedly connected with a nut, so as to facilitate the installation, disassembly and replacement of the guardrail. Attached Figure Description

Detailed Implementation

[0021] 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.

[0022] Reference Figures 1-3This utility model provides an embodiment of a traffic engineering guardrail, comprising a post 1 and a vertical rod 8. First support blocks 2 are slidably connected to both sides of the post 1. A connecting block 3 is slidably connected to the top of the first support block 2, and a first bolt 4 is slidably connected to the top of the connecting block 3. A fixing rod 19 is fixedly connected inside the post 1. A spring 18 is provided at the bottom end of the first support block 2. A lower crossbeam 7 is fixedly connected to the bottom end of the vertical rod 8. A short rod 17 is slidably connected to the inner wall of the vertical rod 8. A gear shaft 13 is provided on the inner wall of the vertical rod 8. A small gear 14 is rotatably connected to the outer wall of the gear shaft 13, and the small gear 14 is meshed on both sides. A rack 15 is connected, and a slider 23 is fixedly connected to the opposite side of the rack 15. A baffle 16 is fixedly connected to the outer wall of one of the sliders 23. An upper crossbeam 6 is fixedly connected to the top of the baffle 16. A second bolt 5 is slidably connected to the top of the upper crossbeam 6. The column 1 is provided with a support and fixing assembly: the support and fixing assembly includes a second support block 10. The second support block 10 passes through the connecting block 3 and is threaded to the inner wall of the nut 12. A fixing block 9 is slidably connected to the inner wall of the second support block 10. Multiple fixing blocks 9 are fixedly connected to the left and right sides of the column 1. A first bolt 4 passes through the connecting block 3 and is threaded to the inner wall of the first support block 2.

[0023] The post 1 is connected to the second support block 10 via a fixing block 9. A third bolt 11 passes through the second support block 10 and is threaded, fixing the second support block 10 to the post 1. A second bolt 5 passes through the connecting block 3 and is threaded to fix the upper crossbeam 6 and the lower crossbeam 7 respectively. The second support blocks 10 on both sides pass through the connecting block 3 and support the lower crossbeam 7. Then, the connecting blocks 3 on both sides of the upper crossbeam 6 are moved to overlap the top of the first support block 2, and the first bolt 4 passes through the connecting block 3 and is threaded to the first support block 2 for fixation. This achieves basic fixation of the guardrail. Finally, the nut 12 is threaded to the second support block 10 to completely fix the guardrail. At the same time, the gears... Shaft 13 is connected inside the vertical rod 8 and to the pinion 14. The pinion 14 meshes with the racks 15 on the left and right sides, so that the racks 15 on both sides move in opposite directions. At the same time, the left rack 15 is connected to the spring 18, and the right rack 15 is connected to the baffle 16 through the slider 23. The downward movement of the upper crossbeam 6 drives the first support block 2 to compress the spring 18, which indirectly drives the spring 18 to move upward. The upward force generated by the spring 18, guided by the fixed rod 19, moves the first support block 2 upward, thereby driving the upper crossbeam 6 and the baffle 16, and indirectly driving the short rod 17 to move in the opposite direction, so as to change the height of the railing.

[0024] Reference Figure 3 The second bolt 5 passes through the connecting block 3 and is threaded to the bottom end of the upper crossbeam 6. The second bolt 5 passes through the connecting block 3 and is threaded to the bottom end of the lower crossbeam 7.

[0025] The upper crossbeam 6 is fixed to the connecting blocks 3 by threading the second bolt 5 to the bottom end of the upper crossbeam 6. The lower crossbeam 7 is also fixed to the connecting blocks 3 on both sides by threading the second bolt 5 to the bottom end of the lower crossbeam 7, thus facilitating the installation and replacement of the guardrail.

[0026] Reference Figure 3 The rack 15 is slidably connected to the inner wall of the vertical rod 8. The left and right sides of the vertical rod 8 are provided with first grooves 20, and the slider 23 is slidably connected to the inner wall of the first grooves 20.

[0027] The rack 15 slides on the inner wall of the vertical rod 8 to ensure the moving position of the rack 15, and the slider 23 slides on the inner wall of the first groove 20, thereby limiting the moving range of the slider 23 and achieving the effect of controlling the up and down moving range of the short rod 17.

[0028] Reference Figure 2 and Figure 3 A third groove 22 is provided on the right side of the short rod 17. The rack 15 is slidably connected to the inner wall of the third groove 22, and the short rod 17 is slidably connected to the outer wall of the pinion 14.

[0029] It has the function of being connected by a rack 15 and a short rod 17. When the short rod 17 contacts the top of the pinion 14, it restricts the downward movement of the short rod 17, thereby achieving the effect of controlling the range of vertical movement of the short rod 17.

[0030] Reference Figure 2 and Figure 3 The vertical rod 8 is slidably connected to the inner wall of the upper crossbeam 6, and the vertical rod 8 is slidably connected to the adjacent side of the two baffles 16, which are slidably connected to the outer side of the first slide groove 20.

[0031] It has the ability to indirectly drive multiple baffles 16 to move by sliding the upper crossbeam 6 and multiple vertical rods 8 up and down, preventing the vertical rods 8 from falling. At the same time, the baffles 16 cover the first sliding groove 20 to prevent impurities from entering the vertical rods 8 from the first sliding groove 20, thereby protecting the internal lifting structure of the vertical rods 8.

[0032] Reference Figure 3 The column 1 has multiple second sliding grooves 21 inside. The first support block 2 is slidably connected to the inner wall of the second sliding groove 21. The spring 18 is slidably connected to the outer wall of the fixed rod 19. The first support block 2 is slidably connected to the outer wall of the fixed rod 19. The spring 18 is located at the bottom end of the second sliding groove 21.

[0033] The first support block 2 moves downward, which compresses the spring 18 and generates an upward force. The upward force generated by the spring 18 pushes the first support block 2 to move upward. The fixing rod 19 prevents the spring 18 from being misaligned with the first support block 2, thus providing an upward elastic force to the first support block 2.

[0034] Reference Figure 1 and Figure 3 The second support block 10 is slidably connected to the outer wall of the column 1. The outer wall of the second support block 10 is slidably connected to the third bolt 11, which passes through the second support block 10 and is threadedly connected to the inside of the fixing block 9.

[0035] The fixing block 9 is connected to the second support block 10 by sliding connection, and the third bolt 11 is threadedly connected to the fixing block 9, so that the second support block 10 is fixed on the column 1. When installing multiple guardrails, it is convenient to connect the bottom of the guardrail to the second support block 10, so as to achieve the effect of quickly installing multiple guardrails.

[0036] Working principle: By applying a downward force to the upper crossbeam 6, the first support block 2 and the baffle 16 move downward. The movement of the baffle 16 drives the rack 15 and slider 23 on the right side, causing the rack 15 to rotate and simultaneously driving the rack 15 and slider 23 on the left side to move upward. This causes the short rod 17 to move upward, compressing the spring 18 in the first support block 2 and generating an upward force. When the force applied to the upper crossbeam 6 is removed, the upward force of the spring 18 on the first support block 2 causes the first support block 2 to move upward, thereby driving the upper crossbeam 6, the baffle 16, and the rack 15 on the right side to move. This causes the pinion 14 to rotate, further driving the rack 15 on the left side to move. The movement of the short rod 17 downwards, while the second slide 21 restricts the upward movement of the upper crossbeam 6, and the first slide 20 restricts the vertical movement of the short rod 17; the second bolt 5 passes through the connecting block 3 to fix it to the upper crossbeam 6 and the lower crossbeam 7 respectively, and the third bolt 11 passes through the second support block 10 to fix it, thereby adjusting the guardrail and the support; the screw of the second support block 10 passes through the connecting block 3 to fix the lower crossbeam 7, while the first bolt 4 passes through the connecting block 3 and is threaded to the first support block 2, and the nut 12 is threaded to the second support block 10, thereby fixing the guardrail and facilitating its installation, disassembly and replacement. This guardrail not only makes pedestrians feel that climbing over the guardrail will cause injury, thus preventing pedestrians from climbing over the guardrail, but also allows for quick installation and disassembly of the guardrail.

[0037] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
