Abstract

The invention discloses a mechanization device for continuously and freely heightening a wave-shaped beam guardrail. The device is characterized in that a gear rack device with a one-way stop device is arranged in a foundation stand column with an inner cavity channel, and a rack is used for pushing an outer sleeve assembly provided with an anti-blocking block sleeving frame and a stand column sleeve; problems that an existing wave-shaped beam guardrail can only be heightened step by step and needs to be disassembled when adjusted can be solved, side face driving, free adjustment and reliable positioning in the height direction of the wave-shaped beam guardrail can be achieved by converting rotation into linear motion through gears and racks and adopting the one-way rotation reverse self-locking performance of a one-way stop device similar to a ratchet wheel, and the wave-shaped beam guardrail is convenient to operate and high in practicability; installation is simple, and construction efficiency can be greatly improved.

Description

technical field

[0001] The invention relates to wave beam guardrail technology, in particular to a mechanized device for realizing continuous and free heightening of wave beam guardrails. The bar pushes the outer casing assembly with the anti-blocking block socket frame and the column casing, which can solve the problem that the current wave beam guardrail can only be increased step by step and must be removed every adjustment. By using the rack and pinion, the rotation is converted into a linear motion. And the one-way stop device is similar to the one-way rotation and reverse self-locking performance of the ratchet, which can realize side drive, free adjustment and reliable positioning in the height direction of the wave beam guardrail, and is easy to operate and easy to install, which is conducive to greatly improving construction efficiency.
