Guardrail with adjustable height and maintenance equipment with same
The invention discloses a guardrail with adjustable height and maintenance equipment with the same. The guardrail with the adjustable height comprises a handrail (1), an upper link mechanism (2), a lower link mechanism (4) and a connecting frame (3). The upper link mechanism and the lower link mechanism are connected through the connecting frame, the handrail (1) is installed at the top end of the upper link mechanism (2), and the installation point of the lower portion of the lower link mechanism is hinged to the installation point on platforms such as a working ladder bed. An adjusting lead screw is driven manually to allow the guardrail to ascend or descend, the guardrail can be reliably fixed at any height, the use range of the guardrail is remarkably widened, especially when the guardrail is applied to the movable working ladder bed platform, the height can be adjusted according to different use practical conditions and maintenance objects, and the guardrail only needs to descend to be completely folded in the transporting process without being detached. The guardrail is simple in structure and easy, convenient and flexible to operate, and achieves high practical application value.
