Adjustable split-type movable hanging basket for bridge maintenance and operating method

Abstract

The invention discloses an adjustable split-type movable hanging basket for bridge maintenance and an operating method. The adjustable split-type movable hanging basket for the bridge maintenance comprises two supporting cross beams, a counterweight platform, a constructing operation platform, walking devices and a hanging frame. During using in actual engineering, the walking counterweight platform with a locking function is placed on the inner side of a bridge guardrail and is spaced by a distance from the guardrail so as to provide a greater torque for a counterweight block, the constructing operation platform on the other side is placed on the outer side of the guardrail in a cantilevered manner, and the guardrail serves as a stressing fulcrum for the two supporting cross beams; according to different bridge types and guardrail sizes, the supporting cross beams of the hanging basket are transversely stretched and retracted and the hanging frame thereof is vertically stretched and retracted so as to meet constructing operation requirements; the hanging basket is moved to a position where the maintenance is required by pushing the walking counterweight platform, and walking wheels are locked by opening bolts fixed to walking wheel hoods, so that the guardrail and a lower flange plate can be maintained and repaired on the operation platform.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and in particular relates to an adjustable and detachable mobile hanging basket for bridge maintenance and an operation method. Background technique [0002] The bridge structure is the lifeblood of highway and railway transportation lines. For example, in my country's existing high-speed rail network, bridges account for a large proportion. At the same time, they are also the throat of the urban transportation network and play a pivotal role in traffic diversion. Of course, the working environment of civil engineering structures, especially bridge structures, determines that they must bear a large number of dynamic loads. Examples of bridge structure damage due to dynamic reasons occur from time to time. In the process of use, affected by many complex factors such as natural environment erosion, material aging and fatigue effects, the reliability and bearing capacity of its structure...
