Description

Technical Field

[0001] The utility model relates to the technical field of guardrails, in particular to a guardrail for highway maintenance. Background Art

[0002] After a highway is built, there will be defects such as potholes and cracks on the road due to long-term driving, so road maintenance is needed. When the highway is undergoing road maintenance construction, it is necessary to set up guardrails on the periphery of the road construction area to remind passing vehicles and pedestrians to avoid them and protect the personal safety of construction workers.

[0003] Most of the existing guardrails are of the straight extension type and cannot be adjusted for turning, and thus cannot be adaptively adjusted according to the curvature of the road. The use of straight guardrails on curved parts of the road will increase the difficulty of construction and require additional processing measures, affecting the construction progress and efficiency. At the same time, gaps are prone to exist at the bends of the road, resulting in poor protection effect. Utility Model Content

[0004] The utility model aims to provide a highway maintenance guardrail which can be adaptively adjusted according to the curvature of the road, and effectively solves the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions.

[0006] A guardrail for highway maintenance comprises a column and a pair of guard frames, wherein clamping rods are respectively arranged on both sides of the column, and the two clamping rods extend vertically respectively, and the two guard frames are distributed on both sides of the column, and a U-shaped frame is respectively arranged on one side of the two guard frames, and clamping holes are respectively arranged at both ends of the two U-shaped frames, and the two ends of the clamping rod are through-and-through matched and clamped in the two clamping holes on the clamping rod on the same side, and the clamping rod can be rotated and adjusted in the clamping holes.

[0007] It can be seen that by matching and inserting the two ends of the clamping rod into the two clamping holes on the U-shaped frame, a clamping effect is achieved, and the protective frame can be connected to the column. In addition, the clamping rod can be rotated and adjusted in the clamping hole, so that the protective frame and the U-shaped frame as a whole and the clamping rod have the ability to rotate relative to each other. By rotating and adjusting the two protective frames separately, the guardrail can be adaptively adjusted to turn according to the curvature of the road to meet the needs of actual use.

[0008] Furthermore, the protection frame includes two vertical poles and a plurality of cross bars, and the plurality of cross bars are fixed between the two vertical poles at intervals along the vertical direction.

[0009] The whole formed by two vertical poles and several horizontal poles has the effect of enclosure.

[0010] Furthermore, fixed blocks are respectively fixed on both sides of the column, and two clamping rods are respectively fixed on the fixed blocks on both sides, and two ends of the clamping rods extend through and extend to the upper and lower parts of the fixed blocks respectively.

[0011] The clamping rod is fixed on the fixing block, and both ends of the clamping rod extend to the outside of the fixing block respectively, so that both ends of the clamping rod are exposed, thereby facilitating clamping into the clamping hole.

[0012] Furthermore, the U-shaped frame includes a mounting seat, a pair of telescopic rods, a pair of clamping plates and a pair of springs. The mounting seat is fixed to the side of one of the vertical rods. The upper and lower end surfaces of the mounting seat are respectively provided with vertically extending telescopic grooves. The two telescopic rods are respectively slidably and telescopically inserted in the telescopic grooves, and the ends of the two telescopic rods away from each other extend to the outside of the mounting seat respectively. Clamping plates are respectively fixed on the ends of the two telescopic rods located outside the mounting seat, and the clamping plates are respectively provided with clamping holes for the clamping rods to be clamped into. Springs are provided in the two telescopic grooves, one end of the spring is fixed to the end face of the telescopic rod located in the telescopic groove, and the other end is fixedly connected to the inner end wall of the telescopic groove.

[0013] By pulling the two clamping plates to the upper and lower sides respectively, the two telescopic rods are driven to slide up and down respectively. At this time, both springs are stretched and charged until the distance between the two clamping plates is greater than the overall length of the clamping rod. The two ends of the clamping rod are aligned with the clamping holes on the upper and lower sides respectively. Then the clamping plates are slowly released. Under the elastic force of the springs, the telescopic rods and clamping plates on the upper and lower sides are driven to reset, so that the two clamping plates are correspondingly clamped on the two ends of the clamping rod to achieve the clamping effect. In addition, the clamping rod fits the inner wall of the clamping hole and has the ability to rotate and adjust. By pulling the two clamping plates to the upper and lower sides respectively again, the two telescopic rods are driven to slide up and down respectively until the distance between the two clamping plates is greater than the overall length of the clamping rod. The two ends of the clamping rod can be disengaged from the clamping holes on the upper and lower sides to achieve disassembly. The overall disassembly and assembly does not require the use of tools, and the disassembly and assembly are convenient and quick.

[0014] Furthermore, two guide grooves are provided on the side surface of the mounting seat, both of which extend vertically and are connected to the two telescopic grooves one by one. A pinch handle is fixed on the side surface of the telescopic rod, and the pinch handle passes through the guide groove and extends to the outside of the mounting seat.

[0015] By pinching the handle, you can easily exert force to pull and adjust the telescopic rod.

[0016] Furthermore, a first counterweight placement seat is fixed at the bottom of the column, and a second counterweight placement seat is fixed at the bottom end of each upright pole.

[0017] The first counterweight placement seat facilitates the vertical arrangement of the column on the road surface, and the second counterweight placement seat facilitates the vertical arrangement of the pole on the road surface, thereby facilitating the overall arrangement of the guardrail and providing high stability.

[0018] Furthermore, a warning sign is fixed on the crossbar, and a warning slogan is provided on the warning sign.

[0019] By arranging a warning sign with a warning slogan on the crossbar, it is convenient to warn pedestrians and vehicles passing by to avoid the road.

[0020] Furthermore, reflective stickers are provided on the pillars, poles, horizontal bars and warning signs.

[0021] By setting reflective stickers to reflect light at night, it can also serve as a warning.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows.

[0023] 1. The utility model realizes a clamping effect by respectively inserting the two ends of the clamping rod into the two clamping holes on the U-shaped frame. The guardrail can be connected to the column. In addition, the clamping rod can be rotated and adjusted in the clamping hole, so that the guardrail and the U-shaped frame as a whole have the ability to rotate relative to the clamping rod. By rotating and adjusting the two guardrails respectively, the guardrail can be adaptively adjusted to turn according to the curvature of the road to meet the needs of actual use.

[0024] 2. The utility model pulls the two clamping plates to the upper and lower sides respectively, driving the two telescopic rods to slide up and down respectively. At this time, the two springs are stretched and stored until the distance between the two clamping plates is greater than the overall length of the clamping rod. The two ends of the clamping rod are aligned with the clamping holes on the upper and lower sides respectively, and then the clamping plates are slowly released. Under the elastic force of the springs, the telescopic rods and clamping plates on the upper and lower sides are driven to reset, so that the two clamping plates are correspondingly clamped on the two ends of the clamping rod to achieve a clamping effect. In addition, the clamping rod fits the inner wall of the clamping hole and has the ability to rotate and adjust. By pulling the two clamping plates to the upper and lower sides respectively again, driving the two telescopic rods to slide up and down respectively, until the distance between the two clamping plates is greater than the overall length of the clamping rod, the two ends of the clamping rod can be disengaged from the clamping holes on the upper and lower sides to achieve disassembly. The overall disassembly and assembly does not require the use of tools, and the disassembly and assembly are convenient and quick. BRIEF DESCRIPTION OF THE DRAWINGS
