Description

Technical Field

[0001] This utility model relates to the field of traffic guardrail technology, and in particular to an adaptive connecting traffic guardrail. Background Technology

[0002] Guardrails are mainly used for roadblocks, villa fences, or roadside fences, etc. They are widely used due to their excellent steel-plasticity, high strength, and corrosion resistance. Currently, guardrails are basically composed of posts, horizontal bars, and vertical bars. The base of the post can be equipped with a base or a moving mechanism. Depending on the device installed at the base of the post, guardrails can be divided into movable guardrails or fixed guardrails.

[0003] Movable guardrails are highly flexible due to their movable mechanism at the bottom. However, when used on uneven surfaces, the bottoms of the two ends of the posts may not be on the same level, causing instability. Since they lack a base, unlike fixed guardrails, the base height cannot be adjusted to ensure the posts are level. In this case, foot pads are needed to adjust the moving mechanism. When using movable guardrails on long stretches of road, this requires purchasing a large number of foot pads of different sizes and performing various adjustments by workers, wasting significant manpower and resources. Therefore, a movable guardrail that can adapt to uneven road surfaces is urgently needed. Utility Model Content

[0004] To address the aforementioned shortcomings, the purpose of this invention is to propose an adaptive connecting traffic guardrail to improve the adaptability of the movable guardrail, enabling it to be used directly on different road surfaces without the need for additional foot pads.

[0005] To achieve this objective, the present invention adopts the following technical solution: an adaptive connecting traffic barrier, comprising:

[0006] A plurality of opposing moving mechanisms, wherein a first mounting component and a second mounting component are respectively provided on the opposing surfaces of the moving mechanisms along the vertical direction;

[0007] The first connecting rod is installed between the two moving mechanisms, and both ends of the first connecting rod are connected to the first mounting component by hinges.

[0008] The second connecting rod is installed between the two moving mechanisms. The end of the second connecting rod is provided with a retractable connecting part, which is connected to the second mounting component.

[0009] Preferably, the second mounting component is a cylinder with an inner groove inside. The diameter of the inlet of the inner groove is larger than the diameter of the connecting part, and the connecting part is inserted into the second mounting component by means of insertion.

[0010] Preferably, the inner groove includes a snap-fit ​​groove and an inlet groove connected in sequence, with the snap-fit ​​groove located on the inner side and the inlet groove located on the outer side;

[0011] The diameter of the snap-fit ​​groove gradually increases from the inside to the outside, and the snap-fit ​​groove is provided with snap-fit ​​nodes, the diameter of which is smaller than the diameter of the connecting part.

[0012] Preferably, the inner wall of the inner groove is provided with rubber.

[0013] Preferably, it also includes at least two reinforcing columns, which are installed between the non-connecting portions of the first connecting rod and the second connecting rod.

[0014] Preferably, it also includes a railing structure, which is disposed between the first connecting rod and the second connecting rod, and the two sections of the railing structure are respectively fixedly connected to the column body of the reinforcing column.

[0015] Preferably, the moving mechanism includes a frame, a power unit, and wheels;

[0016] The outer surface of the frame is provided with the first mounting component and the second mounting component;

[0017] The power unit is located at the bottom of the frame, and the moving wheels are connected by a shaft. The power unit is connected to the shaft for transmission, and the shafts are connected to each other by belt transmission.

[0018] Preferably, the power assembly includes a mounting component, a drive motor, a drive gear, a first driven gear, a second driven gear, a third driven gear, and a fourth driven gear;

[0019] The mounting components include a first panel and a second panel arranged opposite to each other; the driving motor and the first driven gear are mounted on the side of the first panel away from the second panel; the second driven gear and the third driven gear are mounted between the first panel and the second panel; and the fourth driven gear is mounted on the side of the second panel away from the first panel.

[0020] The output end of the active motor is equipped with the active gear, which meshes with the first driven gear. The centers of the first driven gear and the second driven gear are connected by a connecting shaft. The second driven gear meshes with the third driven gear. The centers of the third driven gear and the fourth driven gear are connected by a connecting shaft. The fourth driven gear is connected to the fifth driven wheel on the shaft via a belt.

[0021] The number of teeth on the driving gear is less than the number of teeth on the first driven gear, and the number of teeth on the second driven gear is less than the number of teeth on the third driven gear.

[0022] One of the above technical solutions has the following advantages or beneficial effects: By connecting the first connecting rod in a hinged manner, the first connecting rod can adaptively balance itself according to the slope of the road surface between the two moving mechanisms. Because the slopes of the two moving planes are different, the appropriate length of the second connecting rod located above may be longer or shorter than the first connecting rod. Therefore, the end of the second connecting rod is provided with a retractable connecting part, which can be located at one or both ends of the second connecting rod, allowing selection of the second connecting rod according to different road conditions. By adjusting the length of the connecting part, the second connecting rod can be smoothly inserted into the second mounting component for connection and fixation. Ultimately, this improves the adaptability of the moving guardrail to uneven road surfaces. Attached Figure Description

[0030] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0031] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0032] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] like Figures 1-2 As shown, an adaptive connecting traffic barrier includes:

[0035] A plurality of opposing moving mechanisms (1), wherein the opposing surfaces of the moving mechanisms (1) are respectively provided with a first mounting component (2) and a second mounting component (3) in the vertical direction;

[0036] The first connecting rod (4) is installed between the two moving mechanisms (1), and the two ends of the first connecting rod (4) are respectively connected to the first mounting part (2) by hinge.

[0037] The second connecting rod (5) is installed between the two mechanisms (1). The end of the second connecting rod is provided with a telescopic connecting part, which is connected to the second mounting part (3).

[0038] The guardrail in this utility model is a movable guardrail. In order to enable the movable guardrail to be used directly on uneven road surfaces, a first mounting part (2) and a second mounting part (3) are provided on the side of the movable mechanism (1). The first mounting part (2) is a conventional hinged part, which is connected to the first connecting rod (4) by hinge. Figure 1 As shown, the first connecting rod (4) can adaptively balance according to the slope of the road surface where the two moving mechanisms (1) are located. Since the slope of the plane where the two moving mechanisms (1) are located is different, the length of the second connecting rod (5) located above may be longer or shorter than the first connecting rod (4). Therefore, the end of the second connecting rod (5) is provided with a telescopic connecting part (not shown in the figure). The connecting part can be set at one end or both ends of the second connecting rod (5), and the second connecting rod (5) can be selected according to different road conditions. At this time, by adjusting the length of the connecting part, the second connecting rod (5) can be smoothly inserted into the second mounting part (3) for connection and fixation. In the end, the adaptability of the moving guardrail to uneven road surfaces is improved. It is worth mentioning that when the second connecting rod (5) in this utility model is a straight rod, it is only suitable for roads with uneven surfaces and small slopes. If the road surface has uneven surfaces and large slopes, a curved rod is required as the second connecting rod (5).

[0039] Preferably, the second mounting component (3) is a cylinder with an inner groove inside. The diameter of the inlet of the inner groove is larger than the diameter of the connecting part. The connecting part is inserted into the second mounting component (3) by means of insertion.

[0040] To facilitate the installation of the second connecting rod (5), in one embodiment of this utility model, the second mounting part (3) is set as a cylinder, and the connecting part of the second connecting rod (5) is fixed in the second mounting part (3) by insertion. Due to the slope of the road surface, when the second connecting rod (5) is inserted into the second mounting part (3), the end or connecting part of the second connecting rod (5) is not inserted horizontally, but at a certain angle. At this time, the end or connecting part of the second connecting rod (5) will be better locked in the second mounting part (3), and no additional fixing equipment is needed to fix the second connecting rod (5), which greatly speeds up the installation.

[0041] Preferably, the inner groove includes a snap-fit ​​groove (8a) and an inlet groove (8b) connected in sequence, wherein the snap-fit ​​groove (8a) is located on the inner side and the inlet groove (8b) is located on the outer side;

[0042] The diameter of the snap-fit ​​groove (8a) gradually increases from the inside to the outside, and the snap-fit ​​groove (8a) is provided with a snap-fit ​​node, the diameter of which is smaller than the diameter of the connecting part.

[0043] The guardrail may be used on a flat road surface. In this case, the second connecting rod (5) will be inserted into the second mounting piece at a horizontal angle. Because the diameter of the snap-fit ​​groove (8a) gradually increases from the inside to the outside, when it is inserted into the snap-fit ​​node, since the diameter at the snap-fit ​​node is smaller than the diameter of the connecting part, the end of the second connecting rod (5) or the connecting part can be snapped into the second mounting piece, so as to avoid the first mounting piece located below being subjected to excessive force, which would weaken the overall connection strength of the guardrail.

[0044] Preferably, the inner wall of the inner groove is provided with rubber.

[0045] Because the second connecting rod (5) is installed by insertion and snap-fit, friction occurs between the end or connecting part of the second connecting rod (5) and the inner wall of the inner groove of the second mounting component when the guardrail is moved. This can lead to wear of the second mounting component and the second connecting rod (5) over time, making effective snap-fit ​​impossible. Therefore, in one embodiment of this utility model, rubber is provided on the inner wall of the inner groove to reduce friction between the two and extend the service life of the equipment. At the same time, the rubber has a certain degree of plasticity, which allows for better snap-fit ​​of the second connecting rod (5) during insertion and snap-fit, thereby improving the overall connection strength of the guardrail.

[0046] Preferably, it also includes at least two reinforcing columns (6), which are installed between the non-connecting parts of the first connecting rod (4) and the second connecting rod (5).

[0047] The reinforcing post (6) connects the first connecting rod (4) and the second connecting rod (5), making the force on the first connecting rod (4) and the second connecting rod (5) a whole, thus improving the rigidity of the guardrail. When subjected to external impact or collision, it can effectively prevent the first connecting rod (4) or the second connecting rod (5) from deforming due to a single force.

[0048] Preferably, it also includes a railing structure (7), which is disposed between the first connecting rod (4) and the second connecting rod (5), and the two sections of the railing structure (7) are respectively fixedly connected to the column body of the reinforcing column (6).

[0049] By setting up a guardrail structure (7), the gaps between the reinforcing posts (6) can be effectively filled, preventing some people from walking back and forth through the gaps between the reinforcing posts (6), thus causing the guardrail to lose its original blocking function.

[0050] Preferably, the moving mechanism (1) includes a frame (1a), a power unit (1b), and moving wheels (1c).

[0051] The outer surface of the frame (1a) is provided with the first mounting member (2) and the second mounting member (3);

[0052] The power assembly (1b) is located at the bottom of the frame (1a), and the moving wheels (1c) are connected by a shaft (1e). The power assembly (1b) is connected to the shaft (1e) in a transmission manner, and the shaft (1e) is connected to the shaft (1e) in a transmission manner through a belt (1d).

[0053] Preferred, such as Figure 2 As shown, the power assembly (1b) includes a mounting component, a drive motor (1bc), a drive gear (1bd), a first driven gear (1be), a second driven gear (1bf), a third driven gear (1bg), and a fourth driven gear (1bh).

[0054] The mounting components include a first panel (1ba) and a second panel (1bb) arranged opposite to each other; the driving motor (1bc) and the first driven gear (1be) are mounted on the side of the first panel (1ba) opposite to the second panel (1bb); the second driven gear (1bf) and the third driven gear (1bg) are mounted between the first panel (1ba) and the second panel (1bb); and the fourth driven gear (1bh) is mounted on the side of the second panel (1bb) opposite to the first panel (1ba).

[0055] The output end of the active motor (1bc) is equipped with the active gear (1bd), which meshes with the first driven gear (1be). The centers of the first driven gear (1be) and the second driven gear (1bf) are connected by a connecting shaft. The second driven gear (1bf) meshes with the third driven gear (1bg), and the centers of the third driven gear (1bg) and the fourth driven gear (1bh) are connected by a connecting shaft. The fourth driven gear (1bh) is connected to the fifth driven wheel (1f) on the shaft (1e) via a belt (1d).

[0056] The number of teeth of the driving gear (1bd) is less than the number of teeth of the first driven gear (1be), and the number of teeth of the second driven gear (1bf) is less than the number of teeth of the third driven gear (1bg).

[0057] Since the moving mechanism (1) needs to drive the first connecting rod (4) and the second connecting rod (5) to move when it moves, and the first connecting rod (4) and the second connecting rod (5) have a certain weight, in order to move more stably, this utility model uses driven gears with multiple reduction speeds to realize the transmission of power. First, the driving gear (1bd) is driven by the driving motor (1bc), which drives the first driven gear (1be) to rotate, realizing the first reduction speed, reducing the speed and increasing the output torque. The centers of the first driven gear (1be) and the second driven gear (1bf) are connected by a connecting shaft. When the first driven gear (1be) rotates, it drives the second driven gear (1bf) to rotate. The second driven gear (1bf) drives the third driven gear (1bg) to rotate, realizing the second reduction speed, further reducing the speed and increasing the output torque. By increasing the torque twice, the moving mechanism (1) can drive the heavy frame (1a), the first connecting rod (4) and the second connecting rod (5) to move.
