Description

Technical Field

[0001] The utility model relates to the field of highway guardrails, and more specifically, to a cable-type flexible guardrail. Background Art

[0002] Highway guardrails are devices installed on both sides of the highway for the purpose of protection and isolation. Depending on the type of highway, corresponding highway guardrails need to be installed on both sides of the highway. Therefore, there are many types of highway guardrails. One type of guardrail is formed by integral welding of steel pipes, and the bottom of its column is directly installed on the road through expansion bolts. The connection between the column and the base lacks a corresponding redundant flexible connection structure, which makes it easy for the connection to break when a vehicle hits the guardrail or the base is directly hit and disconnected from the road, making it more troublesome to repair it later. Therefore, we proposed a cable-type flexible guardrail to solve the above problems. Utility Model Content

[0003] 1. Technical problems to be solved

[0004] In response to the problems existing in the prior art, the purpose of the present utility model is to provide a cable-type flexible guardrail, which arranges the connection between the bottom of the column and the mounting base in a rotating connection form, and adopts a pulling mechanism to connect the outside of the column, so that the column connection is flexible and has a certain redundant space for rotational offset, avoiding the use of a hard connection structure, making it less likely for the connection to break when the column is hit, reducing the probability of the mounting base being easily detached from the road, and improving the convenience of inspection and maintenance after a subsequent impact.

A plurality of first ear seats 106 are fixedly welded on the installation base 104 at equal intervals. A second ear seat 107 is fixedly welded on the outer wall of the column 101 at the position corresponding to the first ear seat 106. The first ear seat 106 and the second ear seat 107 are connected by a pulling mechanism 3;

[0027] The pulling mechanism 3 includes a first sleeve section 301 and a second sleeve section 302. A threaded connection section 303 is fixedly connected to the bottom of the second sleeve section 302. An internal thread structure is provided at the top of the inner wall of the first sleeve section 301. The first sleeve section 301 and the second sleeve section 302 are threadedly connected through the threaded connection section 303. A sliding plate 304 is slidably connected inside the first sleeve section 301. A pull rod 305 is fixedly welded to the top of the sliding plate 304, and the top of the pull rod 305 penetrates to the outside of the top of the second sleeve section 302. An ear plate one 306 is fixedly welded to the top end of the pull rod 305. The ear plate one 306 is rotatably connected to the corresponding ear seat two 107 through a first pin shaft. An ear plate two 307 is fixedly welded to the bottom of the first sleeve section 301. The ear plate two 307 is rotatably connected to the corresponding ear seat one 106 through a second pin shaft;

[0028] A first support spring 308 is sleeved outside the pull rod 305. The top and bottom of the first support spring 308 are respectively in contact with the top of the inner wall of the second sleeve section 302 and the top of the sliding plate 304. The outer diameter of the outer wall of the first support spring 308 is equal to the inner diameter of the inner wall of the threaded connection section 303. A second support spring 309 is further provided inside the first sleeve section 301 between the sliding plate 304 and the bottom of the first sleeve section 301. The top and bottom of the second support spring 309 are respectively in contact with the bottom of the sliding plate 304 and the bottom of the inner wall of the first sleeve section 301.

[0029] The working principle of this cable-type flexible guardrail is as follows:

[0030] First, the bolt through holes on the installation bases 104 of several such cable-type flexible guardrails are installed on the specified positions on the road through expansion bolts, and then the hooks 102 between adjacent two columns 101 are connected through the steel cable 2. At this time, the installation work can be completed;

[0031] When a vehicle hits the column 101 or the steel cable 2, an extrusion force is generated on the column 101 or the steel cable 2. At this time, the column 101 deflects, and while deflecting, the pull rod 305 of the pulling mechanism 3 along the impact force direction is compressed inward. At this time, the second support spring 309 is compressed through the connection of the sliding plate 304, generating a certain buffering effect. At the same time, the pull rod 305 of the pulling mechanism 3 along the opposite direction of the impact force is pulled outwards. At this time, the first support spring 308 is compressed through the connection of the sliding plate 304, further generating a certain buffering effect, so as to achieve the blocking effect.

[0032] Embodiment 2:

[0033] In view of the above Embodiment 1, for further description, refer to Figure 3 , the outer wall of the second sleeve section 302 is provided with anti-slip lines. Reflective identification tapes are fixedly pasted on the outer walls of the first sleeve section 301 and the column 101. A plurality of bolt through holes are equidistantly arranged on the installation base 104.

[0034] The sleeve section 1 301 and the sleeve section 2 302 are connected by the external threaded connection section 303, which can facilitate the disassembly and assembly of the internal components of the sleeve section 1 301 and the sleeve section 2 302, and the provision of the anti-slip grooves facilitates the screwing of the sleeve section 2 302 to prevent slipping. The sleeve section 1 301 and the outer wall of the column 101 are fixed with reflective identification tapes, which can increase the eye-catching effect at night.
