Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of traffic safety equipment, in particular to a liftable anti-collision road bollard. Background Art
[0002] In modern urban traffic, the safety protection of roads and streets is of vital importance. Among them, anti-collision road bollards are a common safety protection equipment, which are usually set at the edge of roads and streets to prevent vehicles from crossing the line or illegally occupying lanes, thereby ensuring traffic safety. However, most traditional anti-collision road bollards are fixed, that is, their height and position are fixed, which to some extent limits their effectiveness.
[0003] In order to solve the above problems, some existing technical solutions have proposed liftable anti-collision road bollards, which can be raised when needed to prevent vehicles from passing through, and can be lowered when not needed to allow vehicles to pass through. For example, some solutions have proposed to drive the lifting of anti-collision road bollards through hydraulic systems or electric systems. In addition, some solutions have proposed to achieve stable lifting of anti-collision road bollards by setting up complex mechanical structures.
[0004] However, there are still some problems with the existing liftable anti-collision road bollards. First, the existing lifting mechanism is often complex in structure and has high manufacturing and maintenance costs. Second, the existing anti-collision road bollards may have stability problems during the lifting process. For example, they may tilt or shake during the lifting process, which may affect their use effect and safety. Finally, the existing anti-collision road bollards may have a certain impact on the road surface after being lowered. For example, they may hinder the normal passage of vehicles or affect the flatness of the road surface. Utility Model Content

[0035] Example 1
[0036] like Figure 1-3 A liftable anti-collision road bollard is shown, the anti-collision road bollard comprising:
[0037] The outer cylinder 10 is arranged underground. The outer cylinder 10 is a hollow structure with a top wall and an opening at the top. The opening is connected to the ground.
[0038] The pile body 20 is movably arranged in the outer tube 10. The pile body 20 can extend out of the ground from the opening. A power device 120 for lifting the pile body 20 is provided at the bottom of the pile body 20. The power device 120 can adopt a telescopic motor or a screw rod, that is, the pile body 20 extends out of the outer tube 10 through the telescopic motor or the screw rod.
[0039] The supporting device 30 is sleeved on the pile body 20 and comprises a plurality of supporting legs 40, a movable sleeve 50 and a fixed sleeve 60. When the pile body 20 is fully extended out of the ground, the supporting legs 40 and the pile body 20 are open at 45° to 60°.
[0040] The fixed sleeve 60 is fixedly arranged in the middle of the outer cylinder 10, and the movable sleeve 50 is arranged in the lower part of the pile body 20. The movable sleeve 50 is provided with a plurality of guide columns 70, and the fixed sleeve 60 is provided with guide grooves cooperating with the guide columns 70. A fixing frame is arranged between the support sleeve and the movable sleeve 50, and the fixing frame is composed of three connecting rods distributed in a triangular shape. One end of the connecting rods is hinged to each other, and the other end of the connecting rod is respectively hinged to the end of the supporting foot 40, the middle of the supporting foot 40, and the movable sleeve 50.
[0041] The connecting rod includes a first connecting rod 80, a second connecting rod 90 and a third connecting rod 100;
[0042] One end of the first connecting rod 80 is hinged to the middle of the supporting foot 40, and the other end is hinged to one end of the third connecting rod 100;
[0043] One end of the second connecting rod 90 is hinged to the bottom end of the supporting foot 40, and the other end is hinged to the third connecting rod 100;
[0044] The other end of the third connecting rod 100 hinged with the first connecting rod 80 and the second connecting rod 90 is hinged with the movable sleeve 50;
[0045] One end of the first connecting rod 80 and the third connecting rod 100 is hinged and arranged between one end of the second connecting rod 90 and the third connecting rod 100 and one end of the third connecting rod 100 and the movable sleeve 50 .
[0046] In the present invention, one end at which the first link 80 and the third link 100 are hinged is arranged near one end at which the second link 90 and the third link 100 are hinged, and a limiting portion 110 is also provided on the side of the hinged end of the second link 90 and the third link 100. The limiting portion 110 is used to limit the rotation angle of the first link 80, and the first link 80 abuts against the limiting portion 110 after rotating counterclockwise.
[0047] In this embodiment, the limiting portion 110 adopts an outwardly protruding bolt and nut, that is, the head of the bolt is used to limit the movement position of the connecting rod, so that when the angle between the first connecting rod 80 and the third connecting rod 100 is close to 170°, the limiting portion 110 can clamp the first connecting rod 80 for limiting.
[0048] The position and size of the limiting portion 110 determine the rotation angle of the first connecting rod 80 , that is, the angle between the first connecting rod 80 and the third connecting rod 100 can be changed by adjusting the size and position of the limiting portion 110 .
[0049] Particularly, the pile body 20 is made of stainless steel, a buffer layer is provided on the outer surface of the pile body 20, the buffer layer is made of rubber, and the supporting foot 40 is made of stainless steel.
[0050] First, we design an outer cylinder 10, which is a hollow structure with a top wall and an opening at the top, and the opening is connected to the ground. The outer cylinder 10 has a diameter of 50 cm and a height of 200 cm, and is made of high-strength steel to ensure its stability and durability.
[0051] Next, we movably set a pile body 20 in the outer tube 10, and the pile body 20 can extend from the opening to the ground. The pile body 20 has a diameter of 40 cm and a length of 250 cm, and is made of stainless steel to ensure its corrosion resistance and strength. A power device 120 is provided at the bottom of the pile body 20. The power device 120 is a hydraulic cylinder, model MOB-CA, used to lift the pile body 20.
[0052] Then, we design a support device 30, which is sleeved on the pile body 20. The support device 30 has a plurality of support legs 40, a movable sleeve 50 and a fixed sleeve 60. The support legs 40 are made of stainless steel, the number is 3, and the length is 50 cm. When the pile body 20 is fully extended out of the ground, the support legs 40 and the pile body 20 are open at 45° to 60°.
[0053] Then, we fix the fixed sleeve 60 in the middle of the outer cylinder 10, and the movable sleeve 50 is set at the lower part of the pile body 20. The movable sleeve 50 is provided with a plurality of guide posts 70, and the fixed sleeve 60 is provided with guide grooves matched with the guide posts 70. A fixed frame is provided between the support sleeve and the movable sleeve 50, and the fixed frame is composed of three connecting rods distributed in a triangular shape, one end of the connecting rods is hinged to each other, and the other end of the connecting rod is hinged to the end of the support foot 40, the middle of the support foot 40, and the movable sleeve 50 respectively.

It can provide buffering when the anti-collision road pile is hit and reduce damage to the pile body 20. Through the above steps, we have successfully produced a device for lifting anti-collision road piles. The device has a simple structure, low manufacturing and maintenance costs, good use effect, high safety, and can be lowered to the ground when not needed to avoid affecting the road surface. When needed, it can be raised above the ground to play an anti-collision role.
