Abstract

The invention discloses an adjustable guardrail and engineering equipment, and relates to the technical field of guardrail structures. The adjustable guardrail comprises a handle, an installation sleeve and a limiting piece, wherein the handle comprises a holding part and a telescopic rod, and the holding part and the telescopic rod are connected with each other; the holding part is used for maintainers to hold; a first limiting hole is formed in the side surface of the telescopic rod; a plurality of second limiting holes with different heights are formed in the installation sleeve; the installation sleeve is installed in a maintenance channel of the engineering equipment and sleeves the telescopic rod; the telescopic rod can move along the installation sleeve to enable the first limitinghole to be opposite to any one of the second limiting holes; the limiting piece is arranged in an inner space of the telescopic rod and can extend out of or retract into the telescopic rod via the first limiting hole; and the limiting piece can be clamped in the corresponding second limiting hole when extending out of the telescopic rod so as to limit the movement of the telescopic rod relative tothe installation sleeve. The adjustable guardrail and the engineering equipment have the characteristics of adjustable height and high adaptability.

Description

technical field [0001] The invention relates to the technical field of guardrail structures, in particular to an adjustable guardrail and engineering equipment. Background technique [0002] For engineering equipment, especially excavators, there are generally maintenance passages on it. In order to ensure the safe passage of maintenance personnel, handrails or guardrails are generally provided to provide a holding position and prevent maintenance personnel from accidentally falling from the maintenance passage. [0003] However, the existing guardrails are generally fixedly welded on the maintenance passage, and its height is difficult to adjust, and it is difficult to meet the use requirements of maintenance personnel of different heights, and the safety is low. [0004] In view of this, it is particularly important to develop and design an adjustable guardrail and engineering equipment that can solve the above technical problems. Contents of the invention [0005] The ...
