The invention discloses a guardrail dismounting and replacing device for road maintenance, and relates to the technical field of road guardrail installation. In order to solve the problem that when a guardrail cannot be dismantled, the dismantled guardrail and a new guardrail needing to be installed can be installed at the same time. The device specifically comprises a transport vehicle, second electric sliding rails are fixed to the outer walls of the two sides of the transport vehicle correspondingly, movable frames are slidably connected to the inner walls of the second electric sliding rails, first electric sliding rails are fixed to the outer walls of the movable frames, electric push rods are slidably connected to the inner walls of the first electric sliding rails, and movable frames are rotatably connected to output shafts of the electric push rods; arc-shaped elastic plates are fixed to the inner walls of the two sides of the movable frame correspondingly. After new guardrails in the transport vehicle are all installed, the transport vehicle can be filled with dismantled old guardrails, then a worker can push the transport vehicle to a corresponding position, the dismantled old guardrails are recycled, meanwhile, the new guardrails are loaded into the transport vehicle, and the dismantling and replacing efficiency of the guardrails is improved.

    本发明公开了一种公路养护用护栏拆换装置,涉及道路护栏安装技术领域;为了解决无法对护栏进行拆除的同时,对拆除后的护栏和需要安装的新护栏同事进行的问题;具体包括运输车,所述运输车两侧外壁分别固定有第二电动滑轨,第二电动滑轨内壁滑动连接有活动架,活动架外壁固定有第一电动滑轨,第一电动滑轨内壁滑动连接有电动推杆,电动推杆的输出轴转动连接有活动框,活动框两侧内壁分别固定有弧形弹板。本发明当运输车内部新的护栏都被安装完毕后,运输车内部也会装满拆除的旧的护栏,随后工作人员即可将运输车推动到对应位置,对拆除的旧的护栏进行回收的同时,将新的护栏装入运输车内部,提高护栏的拆除更换效率。
