Portable multi-purpose road and bridge construction ladder

Abstract

The invention relates to the technical field of construction equipment, in particular to a portable multi-purpose road and bridge construction ladder. The portable multi-purpose road and bridge construction ladder comprises a fixing base and outer cylinders. The outer cylinders are fixedly connected with the top end of the fixing base. First-stage piston cylinders are connected with the inner sides of the outer cylinders in a sliding mode, and second-stage piston cylinders are connected with the inner sides of the first-stage piston cylinders in a sliding mode. Fixing shafts are fixedly connected with the right ends of the second-stage piston cylinders, and second-stage telescopic rods are fixedly connected with the right ends of the fixing shafts. A motor is fixedly connected with the right end of one second-stage telescopic rod, and a wire stranding wheel is fixedly connected with the tail end of a main shaft of the motor. By the use of a multi-stage hydraulic cylinder which is formed by the arranged outer cylinders, the first-stage piston cylinders and the like, the working stroke of the ladder can be quite long, the ladder can be contracted to be short when the ladder does notwork, and the portable multi-purpose road and bridge construction ladder is suitable for the occasion with the quite long stroke requirement, and can also well achieve load bearing. In addition, whenthe portable multi-purpose road and bridge construction ladder is used, the ladder crawling time of a worker can be effectively shortened, the physical strength is saved, and the portable multi-purpose road and bridge construction ladder has the enormous economic benefit and the broad market prospect, and is worth using and popularizing.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to a portable multipurpose road and bridge construction ladder. Background technique [0002] Ladder, a tool for daily life. This tool consists of two long thick poles as sides, and a horizontal bar suitable for climbing is crossed in the middle. It is used for climbing. Ladders are divided into lifting single ladders and lifting ladders. To some high places that are difficult to construct, construction ladders are needed for assistance. Therefore, the demand for portable multi-purpose road and bridge construction ladders is increasing. [0003] Most of the road and bridge construction ladders on the market are simple in structure, but the safety factor is low, and when it is necessary to carry out engineering construction on higher buildings, it is very inconvenient to use because of the carrying of tools and materials, and accidents are prone to cause inconvenience....

AI Technical Summary

Problems solved by technology

[0003] Most of the road and bridge construction ladders on the market are simple in structure, but the safety factor is low, and when it is necessary to carry out engineering construction on higher buildings, it is very inconvenient to use because of the carrying of tools and materials, and accidents are prone to cause inconvenience. Necessary loss, therefore, propose a kind of portable multi-purpose road and bridge construction ladder for the problems referred to above
