A water conservancy engineering steel bar crane that can be easily loaded and unloaded and can be lifted efficiently and stably

Abstract

The invention relates to a hydraulic engineering steel bar crane having convenience in loading / unloading and being high-effective and stable in hoisting. The hydraulic engineering steel bar crane includes a support bench; four fixing support feet are installed symmetrically at the two sides of the support bench; an electrically controlled rotary pedestal is fixedly installed on the upper end of the support bench; a main supporting arm is fixedly installed on the upper end of the electrically controlled rotary pedestal; a work arm is rotatably installed on the end of the main supporting arm; a hydraulic telescoping column is fixedly installed on one side of the main supporting arm; a slide block is slidingly installed on the lower end of the middle part of the work arm; a hoisting bearing body is fixedly installed on the lower end of the slide block and includes a balance bearing block and a retracting / releasing rotary shaft; the balance bearing block is slidingly installed under the retracting / releasing rotary shaft; a steel bar hoisting transportation frame is fixedly installed on the lower end of the hoisting bearing body. The crane can hoist and move the steel bars, which are used in hydraulic engineering construction, to a preset work site safely and high-effectively, and is convenient to move and has complete functions.

Description

technical field [0001] The invention relates to the technical field of spreaders for water conservancy projects, in particular to a steel bar crane for water conservancy projects that can be conveniently loaded and unloaded, and can be hoisted efficiently and stably. Background technique [0002] Water conservancy projects are a general term for various engineering constructions built to control, utilize and protect surface and underground water resources and the environment. Projects built to eliminate water damage and develop and utilize water resources are divided into flood control projects and farmland projects according to their service objects. Water conservancy projects, hydropower projects, waterway and port projects, water supply and drainage projects, environmental water conservancy projects, tidal reclamation projects, etc., often use steel bars to build bridges in water conservancy construction. Bundled together and then hooked on the hook of the crane for lifti...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the above problems, the present invention provides a water conservancy engineering steel bar crane that can be easily loaded and unloaded and can be lifted efficiently and stably, which can solve the problem that the existing steel bars are mainly bundled together and then hung on the hook of the crane when lifting and transporting steel bars. Handling, not only the work efficiency is low, but also the steel bars are easy to fall in mid-air due to loose binding during the lifting and handling process, which is a very unsafe problem. It can realize safe and efficient lifting and handling of steel bars, and can also move the crane conveniently. The handling work has been changed, the work efficiency has been greatly improved, and the work performance is good
