Description
Technical Field
The utility model belongs to pavement maintenance device field, concretely relates to portable highway guardrail climbs ladder suitable for wave form roof beam guardrail.
Background
Highway guardrail generally divide into flexible guardrail, semi-rigid guardrail and rigid guardrail, and flexible guardrail generally refers to the cable guardrail, and rigid guardrail generally refers to the cement concrete guardrail, and semi-rigid guardrail generally refers to beam type guardrail, and beam type guardrail is one kind and resists the collision of vehicle volume with the beam structure that the pillar is fixed, relies on the bending deformation and the tensile force of guardrail to resist, and beam type guardrail has certain rigidity and toughness. The deformation of the cross beam is used for absorbing collision energy, damaged parts are easy to replace, a certain sight line induction effect is achieved, the shape of the guardrail can be coordinated with the line shape of a road, the appearance is attractive, and the waveform beam guardrail is widely applied.
In the maintenance work of the expressway, maintenance personnel sometimes need to climb over or climb the guardrail due to work needs, the height of the traditional guardrail is about 1.2 meters, the maintenance personnel do not need to use tools when climbing over, along with the implementation of JTG D81-2017 highway traffic safety facility design specifications, the height of the guardrail of the expressway has been increased to 1.8-2 meters at present, the maintenance personnel can not climb over or climb without using tools, at present, the maintenance personnel can only use a common ladder for climbing over or climbing due to the fact that specialized tools are not available, and the common ladder is simple and crude in structure, inconvenient to use and unsafe.
SUMMERY OF THE UTILITY MODEL
The utility model discloses an aim at solving present highway maintenance during operation, the wave form roof beam guardrail defect of not specializing more the instrument provides a portable highway guardrail ladder that turns over, and its front end sets up wave form roof beam draw-in groove, uses the ladder upper end to pass through the draw-in groove to be fixed on the wave form roof beam, and the ladder is fixed firm, convenient to use, safety.
The utility model discloses a realize through following technical scheme:
the portable expressway guardrail crossing ladder is characterized in that the ladder body is arranged in an inclined mode, a horizontal top platform is arranged at the upper end of the ladder body, a vertical wave-shaped beam fixing plate is arranged at the bottom of the top platform, and a concave clamping groove matched with the wave-shaped beam in thickness is formed in the lower end of the wave-shaped beam fixing plate.
The utility model discloses the width of draw-in groove matches with the thickness of wave form roof beam, and the thickness of wave form roof beam indicates the distance between crest and the trough.
The utility model discloses a wave form roof beam fixed plate is preferred but not limited to be two, and the symmetric distribution is in the bottom both sides of top platform.
The included angle between the ladder body and the top platform of the utility model is 120-140 degrees.
Further, the shape of the slot of the present invention is preferably, but not limited to, an inverted U-shape. The clamping groove is U-shaped, the groove bottom of the clamping groove is of a smooth arc-shaped structure, and the corrugated beam cannot be damaged.
The utility model discloses a draw-in groove degree of depth is darker, passes through the draw-in groove when fixing on the wave form roof beam as top platform, and is reliable and stable.
The utility model discloses a wave form roof beam fixed plate also can set up 1 or more as required.
Further, the utility model discloses top platform side is equipped with the handrail.
The utility model discloses a handrail height is higher, can be hand, can also fix the safety rope, further strengthens the security. The armrest may be open or closed.
Further, the utility model discloses a ladder post of the ladder body is aluminum alloy hollow structure, and its bottom cover is equipped with flexible landing leg, and ladder post bottom one side is equipped with fastening bolt.
The utility model discloses a not suitable overlength of flexible landing leg length to whole back of stretching out, maintenance personnel can be relaxed freely take a step on first footboard and be suitable, because the guardrail height has certain error when the construction, sets up the ladder length to extending structure, can prevent effectively that ladder body bottom from contacting the phenomenon on ground.
The utility model has the advantages of reasonable structure, safe and convenient use. The utility model discloses a ladder body, top platform, handrail etc. all adopt the aluminum alloy hollow structure of light, and are firm durable, light in weight, convenient to use. Use the utility model discloses, maintenance personnel can be convenient, safe overturn or scramble wave form roof beam guardrail.
