Stretching adjustment maintenance ladder for hydraulic engineering

Abstract

The invention discloses a stretching adjustment maintenance ladder for hydraulic engineering. The stretching adjustment maintenance ladder comprises first support frames, fixing blocks, a first support rod, second concave grooves and support columns, wherein a second support frame is fixed below the first support frame, a reinforcing column is arranged inside the second support frame, a first fixing column is fixed on the outer wall of the first support frame, bolts are fixed on the surface of the outer wall of the first fixing column, and the fixing blocks are arranged on the upper end and the lower end of the first fixing column. According to the present invention, the first support frames, the second support frames and the third support frames are integrally connected respectively through the first fixing columns and the second fixing columns, and are respectively and integrally fixed to the first fixing columns and the second fixing columns through the bolts, and the maintenance ladder can stretch through the movement up and down of the first support frames, such that the use range of the maintenance ladder is expanded so as to improve the use performance of the ladder.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a telescopic adjustment maintenance ladder for water conservancy engineering. Background technique [0002] With the rapid development of my country's economy and urban infrastructure, the demand for various new building materials is also increasing. As an auxiliary facility for urban inspection wells, climbing ladders are short for plastic-steel climbing ladders. They can be used in inspection wells, sewage wells and other places. It is convenient for the staff to go up and down the ladder; it is made of round steel and high-strength industrial plastics, with low cost and high performance, so the cost performance is relatively high. [0003] At present, the structure of the maintenance ladder on the market is relatively simple, and it cannot be adjusted correspondingly under different use conditions, which leads to the limitation of the use range of the devi...

Problems solved by technology

[0004] The purpose of the present invention is to provide a telescopic adjustment maintenance ladder for water conservancy projects, which solves the problem that the structure of the maintenance ladder on the market is relatively simple, and it cannot be adjusted correspondingly under different usage conditions, which leads to the use of the device. The range is limited, and the existing telescopic ladder cannot fix the climbing rod in a targeted manner when it is stretched, which leads to the phenomenon that the ladder is prone to breakage when it is stretched, and then causes damage to the device. At the same time, the use of the ladder issues affecting the performance of
