Description

Technical Field

[0001] This utility model relates to the field of highway technology, specifically to a reversible lane guardrail for urban roads. Background Technology

[0002] With economic development, urban traffic congestion has become increasingly prominent, especially during morning and evening rush hours, which is a common traffic problem in large cities. Some cities use tidal lanes, also known as reversible lanes, which use reversible lane barriers to change the direction of travel in lanes in order to solve existing traffic congestion problems.

[0003] Existing reversible lane barriers are sometimes pushed as a whole without separating the barriers, which is laborious and increases the workload of workers. Moreover, the overall trajectory is difficult to control, making it difficult to accurately position the barrier to the isolation position. Other barriers are disassembled, moved to different positions, and then reassembled, but the installation operation is complicated, and the separated barriers are prone to getting confused. Utility Model Content

[0004] The purpose of this utility model is to provide a reversible lane isolation barrier for urban roads, in order to solve the problems mentioned in the background art. Some existing reversible lane isolation barriers do not separate the barriers and push them as a whole, which is more laborious to operate, increases the labor intensity of workers, and makes it difficult to control the overall trajectory and accurately position the barrier to the isolation position. Other barriers are disassembled, moved to different positions, and then reassembled, but the installation operation is complicated and the separated barriers are prone to confusion.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a reversible lane isolation guardrail for urban roads, comprising a guardrail, wherein the guardrail is composed of two sets of uprights and isolation barriers between them, the uprights comprising vertical support members, a base and casters, the vertical support members being fixed on the base, the casters being fixed on the bottom of the base, and a guardrail positioning seat, adjacent sets of guardrails being connected by guardrail connectors, the guardrail connectors comprising positioning members, rotating rods, connecting half-boxes and connecting straps, the positioning members being installed on the vertical support members, the rotating rods being hinged to the positioning members, the connecting half-boxes being fixed on the rotating rods, and the two ends of the connecting straps being respectively fixed inside the connecting half-boxes of the adjacent sets of guardrails, the connecting half-boxes of the adjacent sets of guardrails having an opening and closing structure.

[0006] Preferably, the two sets of connecting half-boxes are fixed together by a limiting buckle and a rotating buckle. The limiting buckle and the rotating buckle are respectively distributed on the outside of the two sets of connecting half-boxes. The rotating buckle is hinged to the outside of the connecting half-box. When the two sets of connecting half-boxes are combined, one end of the rotating buckle is limited in the groove of the limiting buckle.

[0007] Preferably, multiple sets of connecting straps are provided between the connecting half-boxes, and the connecting straps are made of elastic material.

[0008] Preferably, the guardrail positioning seats are provided in two sets, respectively arranged on both sides of the guardrail parallel to the isolation barrier. The guardrail positioning seats include ground-mounted baffles, which are slidably connected to the uprights at both ends of the guardrail. When the ground-mounted baffles are not sliding upwards, the bottom of the ground-mounted baffles is in contact with the ground.

[0009] Preferably, the bottom of both sides of the upright is provided with sliding grooves, and the pulleys at both ends of the ground-mounted baffle are correspondingly arranged in the sliding grooves.

[0010] Preferably, the guardrail positioning seat further includes a ground-mounted baffle lifting bracket, the bottom of which is connected to the side of the ground-mounted baffle near the guardrail, and the top of which is hooked onto the upper horizontal support of the isolation baffle.

[0011] Preferably, the ground-mounted baffle lifting bracket includes a support rod, a spring element, and a hook. The support rod is connected to the ground-mounted baffle, and the support rod is connected to the hook at the top via the spring element.

[0012] Preferably, the support rod is hinged to the ground-mounted baffle, and the hook is hinged to the spring.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention, through the design of connecting half-boxes and connecting straps, allows the two sets of guardrails to move in stages while the connecting half-boxes are separated. Moving one set does not simultaneously affect the other, making group movement of the guardrails more labor-saving and facilitating precise positioning of each set without being dragged by adjacent guardrails. Furthermore, the merging and separating of the connecting half-boxes is simple and easy to adjust at any time. The connecting straps between the separated connecting half-boxes serve as guides, allowing the guardrails to be reassembled in their moved positions in sequence. The connecting straps also ensure that during movement, the separated guardrails only move within the range of lane changes, and can be quickly reassembled after the lane change is complete.

Detailed Implementation

[0025] 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.

[0026] One embodiment provided by this utility model: as follows Figure 1 As shown, a type of reversible lane divider for urban roads, such as... Figure 1 As shown, it includes guardrail 1, guardrail positioning seat 2, and guardrail connector 3.

[0027] like Figure 2 and Figure 3As shown, the guardrail 1 is composed of two sets of uprights 11 and the isolation barrier 12 between them. The uprights 11 include vertical support members 111, bases 112, reflectors 113, and casters 114. The vertical support members 111 are fixed to the bases 112, and the casters 114 are fixed to the bottom of the bases 112, so that each set of guardrails 1 can be quickly moved when the tidal lane changes. The reflectors 113 are set on the side of the vertical support members 111, which can make the guardrail more visible during nighttime driving and protect traffic safety. The isolation barrier 12 includes an upper horizontal support member 121, a stop bar 122, and a lower horizontal support member 123. The stop bar 122 is evenly distributed between the upper horizontal support member 121 and the lower horizontal support member 123.

[0028] like Figure 4 and Figure 5 As shown, two sets of guardrail positioning seats 2 are provided, respectively located on both sides of the guardrail 1 parallel to the isolation barrier 12. Each guardrail positioning seat 2 includes a ground-mounted baffle 21 and a ground-mounted baffle lifting bracket 22. The ground-mounted baffle 21 is slidably connected to the uprights 11 at both ends of the guardrail 1. Slide grooves 1111 are provided at the bottom of both sides of the uprights 11, and pulleys 211 at both ends of the ground-mounted baffle 21 are correspondingly located within the slide grooves 1111. The bottom of the ground-mounted baffle lifting bracket 22 is connected to the side of the ground-mounted baffle 21 closest to the guardrail 1, and the top of the ground-mounted baffle lifting bracket 22 can be hooked onto the upper horizontal support member 121 of the isolation barrier 12. Figure 6 As shown, the ground-level baffle lifting bracket 22 includes a support rod 221, a spring member 222, and a hook 223. The support rod 221 is connected to the ground-level baffle 21, and the support rod 221 is connected to the hook 223 at the top through the spring member 222.

[0029] Before adjusting the position of guardrail 1 to change the lane, the staff pulls the ground-mounted baffle lifting bracket 22 upward. Under the action of the spring 222, the hook 223 is easily hooked onto the upper horizontal support 121. At the same time, the ground-mounted baffle lifting bracket 22 drives the ground-mounted baffle 21 to slide upward. The bottom of the ground-mounted baffle 21 leaves the ground. Without being affected by the ground-mounted baffle 21 falling to the ground, the guardrail 1 can move flexibly under the action of the caster wheel 114.

[0030] like Figure 2 , Figure 3 and Figure 7As shown, two adjacent sets of guardrails 1 are connected by guardrail connectors 3. The guardrail connectors 3 include positioning parts 31, rotating rods 32, connecting half-boxes 33, and connecting straps 34. Two sets of positioning parts 31 are installed on the vertical support 111. The two ends of the rotating rods 32 are respectively hinged to the corresponding positioning parts 31. The connecting half-boxes 33 are fixed on the rotating rods 32. The two ends of the connecting straps 34 are respectively fixed inside the connecting half-boxes 33 of the two adjacent sets of guardrails 1. Multiple sets of connecting straps 34 are provided between the connecting half-boxes 33. The connecting straps 34 are made of elastic material.

[0031] The connecting half-box 33 between two adjacent sets of guardrails 1 has an opening and closing structure, and the two sets of connecting half-boxes 33 can be fixed together by a limit buckle 331 and a rotating buckle 332, such as Figure 8 As shown, the limiting buckle 331 and the rotating buckle 332 are respectively distributed on the outside of the two sets of connecting half boxes 33. The rotating buckle 332 is hinged to the outside of the connecting half box 33. When the two sets of connecting half boxes 33 are combined, one end of the rotating buckle 332 is limited in the groove of the limiting buckle 331.

[0032] Before moving guardrail 1, open the connecting half-box 33 where the two sets of guardrail 1 are merged. Rotate the rotating buckle 332 to release the restriction of the limiting buckle 331, and the connecting half-box 33 separates. At the same time, the two sets of guardrail 1 can also be moved in stages. When one set is moved, the other set will not be affected simultaneously. Compared with the method of moving guardrail 1 as a whole, moving guardrail 1 in groups is more labor-saving and makes it easier to position each set in an accurate position without being dragged by adjacent guardrail 1. At the same time, the merging and separating of the connecting half-box 33 is simple and easy to adjust at any time. Compared to the method of completely disassembling and moving guardrail 1, the separated connecting half-boxes 33 are connected by a connecting strap 34. The rotating rods 32 of the two separate sets of guardrail 1 can follow the rotation angle. The connecting strap 34 extends as the distance between the guardrail 1 increases, and the connecting strap 34 plays a guiding role, allowing the guardrail 1 to be reassembled in the moved position in sequence. At the same time, the setting of the connecting strap 34 ensures that during the movement, the separated guardrail 1 only moves within the range of lane change, avoiding long movement distances. After the lane change is completed, the guardrail 1 can be quickly reassembled. The guardrail 1 is moved in groups and reassembled to complete the handling of tidal lanes and achieve the effect of traffic flow. Within the range of the movement operation distance of the guardrail 1 changing lanes, the elasticity of the connecting strap 34 will not affect the stability of the connected guardrail 1. The elasticity of the connecting strap 34 also allows the length of the connecting strap 34 to shorten when the two sets of connecting half-boxes 33 come close, thus facilitating the quick arrangement of the connecting strap 34 inside the connecting half-boxes 33 when they are connected.

[0033] When the guardrails 1 are arranged in the combined state of the connecting half box 33, the angle between the two sets of guardrails 1 can be adjusted by rotating the rotating rod 32 between the guardrails 1. This is suitable for curved lanes or for use at the starting position of lane changes.

[0034] When the guardrail 1 is moved to the appropriate position, the hook 223 of the ground-mounted baffle lifting bracket 22 is removed from the upper horizontal support 121. The ground-mounted baffle 21 slides down and makes the bottom contact with the ground. At this time, on the one hand, the contact area between the ground-mounted baffles 21 on both sides and the ground is large, which restricts the movement of the casters 114 and ensures that the position of the guardrail 1 is fixed, preventing the position of the guardrail 1 from shifting with the casters 114. On the other hand, the ground-mounted baffles 21 on both sides add gravity to the bottom of the guardrail 1, improves the stability of the guardrail 1, and makes it less likely to tip over.

[0035] like Figure 9 As shown, when the ground-mounted baffle 21 does not need to be lifted by the ground-mounted baffle lifting bracket 22, the support rod 221 of the ground-mounted baffle lifting bracket 22 can be rotated from a vertical state to a state parallel to the ground-mounted baffle 21. This allows the ground-mounted baffle lifting bracket 22 to be retracted into the inner side of the ground-mounted baffle 21, which is not easily visible, and is limited by the retaining edge 212 on the inner side of the ground-mounted baffle 21. The support rod 221 is hinged to the ground-mounted baffle 21, and the hook 223 is hinged to the spring member 222. The direction of the hook 223 can be rotated, and the hook 223 will not collide with the isolation baffle 12 when the support rod 221 is retracted.

It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description.
