Embodiment

[0027] The portable bridge detection hanging ladder in this embodiment includes an upper end, a middle part and a lower end.

[0028] Hook assembly 1: located at the upper end of the portable bridge detection hanging ladder, the hook assembly 1 is an inverted U-shaped structure, the hook assembly 1 can be hung on the bridge; the end of the hook assembly 1 that is not connected to the middle straight ladder 23 is provided with at least a pair of horizontal Fastening bolts 11, the fastening bolts 11 can be tightened to abut against the bridge body, so as to realize the fastening and fixing between the hook assembly 1 and the bridge components. The hook assembly 1 mainly plays the role of force transmission and fixation. When in use, the hook is first hung on the beam, and then the upper part and the beam body are fixed together by screwing the fixing screw at the end of the hook. The upper column and the running stick form a conventional ladder structure, the column can be supp...

Abstract

The invention relates to a portable bridge detecting hanging-ladder. The portable bridge detecting hanging-ladder comprises a hook assembly at the upper end, a connection assembly on the middle part and a supporting assembly at the lower end, the hook assembly is of an inverted U-shaped structure, and the hook assembly is used for hanging on the bridge body and providing vertical supporting; the connection assembly is composed of a plurality of detachable or connected central straight ladders, and the central straight ladders are connected to the lower end of the hook assembly; the supporting assembly comprises a lower straight ladder and a pedal structure connected to the lower straight ladder. Compared with the prior art, the portable detachable bridge detecting hanging-ladder which can adapt to various bridge structures and complicated construction topography is provided, and solid connection of a hanging ladder and a bridge body can be realized by the cooperation of the upper U-shaped hook assembly and bolts. Under the premise of ensuring safety, the self-weight of the structure can be reduced as much as possible, and the portability of the equipment is increased through disassembly, and the applicable scope of a ladder stand and interoperability of accessories are expanded based on the splicability of the elements.

Description

technical field [0001] The invention relates to the field of bridge maintenance and detection, in particular to a portable bridge detection hanging ladder. Background technique [0002] For a bridge, the completion of construction and putting into use is only the first step to its success. During its long service life, inspection and maintenance are the key to maintaining its safety performance. Statistics as of October 2018 show that China has a total of more than one million road and railway bridges, making it a well-deserved bridge country. The long-term maintenance and repair of such a large number of bridges requires huge manpower and material resources, so bridge inspection equipment must withstand many tests such as economy, safety and adaptability. [0003] The bridge inspection platform is an important auxiliary tool to ensure the smooth implementation of bridge inspection work. The current bridge inspection platform includes bridge inspection vehicles, fixed supp...
