Description

Technical Field

[0001] This utility model belongs to the technical field of highway guardrails, and in particular relates to a highway construction guardrail. Background Technology

[0002] Highway construction guardrails are generally used during highway construction, but in some temporary road construction and maintenance processes, guardrails that guide lane changes are installed on the road to ensure the safety of the construction site and passing vehicles.

[0003] In some temporary work, cones are often used as guardrails. However, these guardrails are weak and not safe enough. Therefore, water-filled barriers are used as guardrails to enhance their impact resistance. However, these impact-resistant protective facilities are heavy. When used for diversion, they need to be arranged in a special curve. The operators need to judge and adjust the placement of the barriers. Without calibration reference, repeated adjustments and relocations are required later, which increases the workload of the on-site setup operators. Utility Model Content

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0029] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0030] This utility model embodiment provides a highway construction guardrail, such as... Figures 1-6 As shown, the highway construction guardrail includes:

[0031] Several groups of guardrail bodies 100, each guardrail body 100 having a first assembly end 310 and a second assembly end 320 at both ends, and different guardrail bodies 100 being connected by connectors 200; the interior of the guardrail body 100 can be a hollow structure, and weight is increased by a method similar to filling a water-filled barrier, thereby improving the impact resistance of the guardrail body 100.

[0032] Connector 200 includes a first connecting rod 210 and a second connecting rod 220. The first connecting rod 210 includes a deflection rod 212 and a first connecting rod 211 disposed on the deflection rod 212. One end of the second connecting rod 220 is provided with an adjusting ring 221, which is rotatably connected to the first connecting rod 211.

[0033] The end of the first connecting rod 210 away from the deflection rod 212 is connected to the first assembly end 310 on the guardrail body 100, and the end of the second connecting rod 220 away from the deflection rod 212 is connected to the second assembly end 322 on the adjacent guardrail body 100.

[0034] The adjusting ring 221 is provided with a limiting hole 223, and the deflecting rod 212 is provided with a locking hole 213 that matches the limiting hole 223. The limiting hole 223 and the locking hole 213 are connected and fixed by bolts.

[0035] The adjusting ring 221 is provided with several sets of limiting holes 223. When the second connecting rod 220 and the first connecting rod 210 are deflected to a certain angle, one set of limiting holes 223 and the locking hole 213 correspond to each other, so that the first connecting rod 210 and the second connecting rod 220 in the connector 200 can present a specific angle. Here, the limiting holes 223 and the locking holes 213 are aligned and then fixedly connected by limiting bolts.

[0036] In the actual assembly process, after the previous set of guardrail bodies 100 is placed, the next set of guardrail bodies 100 is determined according to the position of the connector 200. The positioning of the connector 200 facilitates the formation of a preset specific route for the guardrail bodies 100, reducing the need for repositioning the guardrail bodies 100. When it is necessary to guide traffic flow to change lanes during temporary construction on the highway, the guardrail bodies 100 can quickly form a specific guiding path under the action of the connector 200, reducing the need for path adjustment of the guardrail bodies 100.

[0037] When arranging the position of the guardrail body 100, keeping it flush with the connecting end can reduce the movement of the guardrail body 100 to form a specific curve, reduce the difficulty for operators to operate the guardrail body 100, and facilitate the rapid arrangement of the guardrail body 100. In case of improper adjustment of the position of the guardrail body 100, the limiting hole 223 and the locking hole 213 can be released, and the first connecting rod 210 and the second connecting rod 220 can be adjusted to a suitable angle to adapt to the positional relationship between adjacent guardrail bodies 100, thereby reducing the need for the guardrail body 100 to move.

[0038] In a preferred embodiment of this invention, the first assembly end 310 has a limiting slot 311 on its end face, and a connecting end block 312 is provided in the limiting slot 311. The first connecting rod 211 is nested on the connecting end block 312 away from the deflection rod 212. The connecting end block 312 includes a locking pin 3221 and a support plate 3222. The locking pin 3221 is disposed on the support plate 3222. The end of the first connecting rod 211 has a ring structure that can be directly nested on the locking pin 3221.

[0039] The width of the limiting slot 311 is greater than the width of the first connecting rod 211. The large size of the limiting slot 311 is mainly to prevent the first connecting rod 211 from being difficult to engage with the limiting slot 311 during docking, thus preventing the guardrail body 100 from moving. The large size is used to compensate for positional deviations during docking and reduce small-amplitude offset adjustments. The limiting slot 311 also serves to ensure that the guardrail body 100 and the connector 200 can maintain a certain angular relationship, which is convenient for position calibration and allows the positional relationship to be directly determined when the guardrail body 100 is lowered.

[0040] In this embodiment, the first assembly end 310 and the second assembly end 320 have the same structure. The second connecting rod 220 is provided with a nested ring 222 away from the adjusting ring 221. The nested ring 222 is also connected to the second assembly end 320 through a nested connection. It should be noted that the first connecting rod 210 and the second connecting rod 220 are misaligned with each other. Therefore, the first assembly end 310 and the second assembly end 320 are set at different heights to avoid lack of support when the first connecting rod 210 and the second connecting rod 220 are nested.

[0041] It should be noted that, for the sake of simplicity, the foregoing embodiments are all described as a series of actions. However, those skilled in the art should understand that the present invention is not limited to the described order of actions, as some steps may be performed in other orders or simultaneously according to the present invention. Furthermore, those skilled in the art should also understand that the embodiments described in the specification are preferred embodiments, and the actions and modules involved are not necessarily essential to the present invention.
