Description

Technical Field

[0001] The utility model relates to the technical field of traffic facilities, in particular to a movable guardrail. Background Art

[0002] Traffic guardrails are safety facilities used to separate lanes, guide traffic flow, and protect pedestrians and vehicles. There are various types, including central isolation guardrails, edge guardrails, movable guardrails, etc. Each guardrail has its specific uses and design standards to adapt to different traffic environments and safety requirements.

[0003] Among them, movable guardrails are widely used in scenarios that require flexible lane adjustment due to their advantage of being able to adjust positions flexibly, such as tidal lanes, road maintenance sections, temporary traffic control sections, road construction sections, etc.

[0004] However, the existing movable guardrails have the problem of poor stability compared with fixed guardrails. They are easily blown down or displaced under the action of strong winds. The fallen movable guardrails not only fail to warn vehicles but also affect the normal driving of vehicles. On the other hand, the displacement of movable guardrails caused by strong winds will change the original controlled area, causing vehicles to affect the controlled area. Therefore, there is an urgent need for a movable guardrail with good stability. Summary of the Utility Model

[0005] For this reason, the technical problem to be solved by the utility model is to overcome the problem that the existing movable guardrails are easily blown down or displaced under the action of strong winds, and thus provide a movable guardrail with good stability.

[0006] To solve the above technical problem, the utility model provides a movable guardrail, including: two railing frames, a railing is connected between the two railing frames, and a

[0007] cavity is provided in the lower half of the railing frame, a counterweight is provided in the cavity, and

[0008] supporting members are also provided on both sides of the railing frame. The supporting members gradually extend outward from the railing frame from top to bottom, and the extending direction of the supporting members is perpendicular to the setting direction of the railing on the horizontal plane.

[0009] As a further improvement of the utility model, slots and plug-in members are respectively provided on the two railing frames, and the plug-in members are adapted to the slots.

[0010] As a further improvement of the utility model, the cavity is located below the slot.

[0011] As a further improvement of the utility model, a door panel is provided on one side of the cavity, and the door panel is connected to the side of the railing frame facing away from the railing.

[0012] As a further improvement of the present utility model, the bottom surface of the support member is a rough surface provided with continuous wrinkles.

[0013] As a further improvement of the present utility model, there are at least two railings, and the railings are arranged between two railing frames from top to bottom.

[0014] As a further improvement of the present utility model, it further includes a vertical rod, and both ends of the vertical rod are respectively connected to the two railings at the topmost and bottommost ends.

[0015] As a further improvement of the present utility model, there are at least two vertical rods, and the vertical rods are arranged in sequence from left to right.

[0016] As a further improvement of the present utility model, at least four continuous arc-shaped notches are provided at the bottom of the railing.

[0017] As a further improvement of the present utility model, the support member and the railing frame are integrally formed.

[0018] The above technical solution of the present utility model has the following advantages compared with the prior art:

[0019] A movable guardrail of the present utility model reduces the overall center of gravity of the guardrail through a counterweight member arranged in the cavity. At the same time, the support members on both sides of the railing frame support the guardrail, making the movable guardrail more stable when blown by the wind. By reducing the center of gravity and providing support for the wind-receiving surface in two ways, the stability of the movable guardrail is improved, and the probability of the movable guardrail being blown down in the face of strong wind is further reduced.

[0025] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the embodiments cited do not limit the present utility model.

[0026] It should be noted that when an element is referred to as being "arranged on" or "fixed on" another element, it can be directly on the other element or there can also be an intermediate element. When an element is referred to as being "fixed on" another element or "fixedly connected" to another element, the connection between them can be a detachable fixing method or a non-detachable fixing method. When an element is considered to be "connected" or "rotatably connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right", "up", "down" and similar expressions are only for the purpose of illustration and do not represent the only implementation manner.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0028] The "first", "second", "third", etc. used in the present utility model do not represent specific quantities and sequences, but are only used for name distinction.

[0029] In some embodiments, referring to Figures 1 - 3 as shown, a movable guardrail of the present utility model includes: two railing frames 1, a railing 2 is connected between the two railing frames 1, and a

[0030] cavity 101 is provided in the lower half of the railing frame 1, a counterweight is provided in the cavity 101, and support members 102 are further provided on both sides of the railing frame 1.

[0031] The support members 102 gradually extend outward from the railing frame 1 from top to bottom, and the extending direction of the support members 102 is perpendicular to the setting direction of the railing 2 in the horizontal plane.

[0032] When the mobile guardrail is in use, if it is affected by strong winds parallel to the setting direction of the railing 2, due to the relatively narrow overall width of the guardrail, the windward area is small, so there is no hidden danger in stability. If it is affected by strong winds perpendicular to the setting direction of the railing 2, the support member 102 plays a role in supporting and stabilizing the railing frame 1, preventing the mobile guardrail from being blown down. At the same time, since the counterweight member provided in the cavity 101 is located in the lower half of the railing frame 1, it can reduce the overall center of gravity of the railing frame 1, further reducing the overall center of gravity of the mobile guardrail and making its stability stronger.

[0033] It should be noted that the counterweight member can be any heavy object filled with a material of relatively high density, such as sandbags, and different heavy objects can be selected according to different wind forces.

[0034] In one embodiment, referring to Figure 1 and Figure 3 as shown, the two railing frames 1 are respectively provided with a slot 103 and a plug-in member 104, and the plug-in member 104 is adapted to the slot 103.

[0035] The adjacent two mobile guardrails can be quickly connected or disassembled through the adapted slot 103 and plug-in member 104, thereby improving the use efficiency. At the same time, connecting the adjacent mobile guardrails by plugging can further enhance the overall stability and further reduce the possibility of being blown down by strong winds.

[0036] It should be noted that the slot 103 can be a segmented slot with a "convex" cross-section. After the plug-in member 104 is inserted into such a slot 103, it can form a limit in the horizontal direction to prevent the plug-in member 104 from moving horizontally and coming out of the slot 103.

[0037] In one embodiment, referring to Figures 1 - 2 as shown, the cavity 101 is located below the slot 103.

[0038] Setting the cavity 101 below the slot 103 can not only prevent the cavity 101 and the counterweight member from affecting the use of the slot 103, but also enable the counterweight member to be closer to the bottom end of the mobile guardrail, thereby further reducing the center of gravity.

[0039] In one embodiment, referring to Figures 1 - 2 as shown, one side of the cavity 101 is provided with a door panel 105, and the door panel 105 is connected to the side of the railing frame 1 facing away from the railing 2.

[0040] When it is necessary to place the counterweight member in the cavity 101, open the door panel 105, put in the counterweight member and then close the door panel 105, so that the counterweight member is kept in the cavity 101. The door panel 105 can prevent the counterweight member from detaching from the cavity 101 and facilitate the access of the counterweight member at the same time.

[0041] In one embodiment, the door panel 105 is hinged to the railing 1 for easy opening and closing.

[0042] In one embodiment, referring to Figures 1 - 2 as shown, the bottom surface of the support member 102 is a rough surface provided with continuous wrinkles.

[0043] By providing the rough surface on the bottom surface of the support member 102, the friction coefficient between the support member 102 and the ground is increased, thereby increasing the frictional force between the support member 102 and the ground and reducing the situation of displacement after the movable guardrail is placed.

[0044] In one embodiment, referring to Figure 1 as shown, there are at least two railings 2, and the railings 2 are arranged between two railings 1 from top to bottom.

[0045] By providing a plurality of railings 2, the stability of the connection between the railings 1 is improved, thereby improving the overall stability of the movable guardrail and avoiding the situation of deviation between the two railings 1.

[0046] In one embodiment, referring to Figure 1 and Figure 3 as shown, it further includes a vertical rod 3, and both ends of the vertical rod 3 are respectively connected to the two railings 2 at the topmost and bottommost ends.

[0047] By providing the vertical rod 3, it plays a role in strengthening the support of the railing 2, improves the stability of the railing 2, makes the overall connection structure of the railing 2 more stable, and is not easily deformed when resisting strong winds.

[0048] In one embodiment, referring to Figure 1 and Figure 3 as shown, there are at least two vertical rods 3, and the vertical rods 3 are arranged in sequence from left to right.

[0049] By providing a plurality of vertical rods 3, the support of the vertical rods 3 on the railing 2 is more uniform, further improving the overall stability of the movable guardrail. At the same time, it is not easily deformed when resisting strong winds.

[0050] In one embodiment, referring to Figure 1 as shown, at least four continuous arc-shaped notches are provided at the bottom of the railing 2.

[0051] The arc-shaped notches provided at the bottom of the railing 2 can make the posture of holding the hand more suitable when lifting the movable guardrail, making the movable guardrail more convenient to hold when disassembling, connecting and displacing.

[0052] In one embodiment, referring to Figures 1 - 2 as shown, the support member 102 and the railing 1 are integrally formed.

[0053] The integrally formed support member 102 and the hurdle 1 can make the connection between the two more stable, thereby improving the overall structural stability of the two.

[0054] Obviously, the above embodiments are only examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present utility model.
