Beam crane with top-arranged angular trolley

Abstract

The invention discloses a beam crane with a top-arranged angular trolley. The two ends of a main beam are fixedly connected to end beams, a main beam top cover plate extends out of a main beam main web plate and a main beam auxiliary web plate for forming outer edge beam plates, the angular trolley is installed on the main beam, a square rail is welded to the upper surface of the main beam top cover plate, the angular trolley rolls along the square rail, and operation stop devices are welded to the two ends of the square rail; electrical equipment is connected to the angular trolley through a cable; a frame of the angular trolley is provided with a driving assembly, a hoisting electric block, a rolling wheel type tilting-preventing mechanism and a safety hook structure, and the rolling wheel type tilting-preventing mechanism and the safety hook structure are both installed in cooperation with the outer edge beam plates. According to the beam crane, the hoisting electric block is arranged at the upper part of the main beam, the lifting height can be effectively increased by more than 1.5 meters, the civil engineering cost can be effectively saved, the shortcomings that the lifting height of traditional beam cranes is small, the traditional beam cranes shake easily in the work process and positioning of suspended loads is difficult can be overcome, and the economical benefits are remarkable.

Description

technical field [0001] The invention relates to an electric single-girder crane, in particular to an electric single-girder crane with an upper-mounted angle trolley structure. Background technique [0002] Hoisting machinery is a kind of special equipment with high risk. At present, there are a large number of hoisting machinery in use in my country. According to the "2015 Zhejiang Province Special Equipment Safety Status Report", there are 240,552 hoisting machinery, and electric beam cranes account for the majority of them. From the perspective of accident-prone equipment, electromechanical Equipment accounts for the vast majority. [0003] Beam cranes are light and small lifting equipment. In the hoisting machinery, the light and small hoisting equipment that uses the electric wire rope hoist as the hoisting mechanism and mostly uses the ground manipulation form is often called a beam crane. Compared with other cranes of the same tonnage and span, the beam crane has th...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the shortcomings of existing beam cranes such as low lifting height, lifting electric hoist suspended under the main girder, easy shaking during work, difficult positioning of hoisting load, easy falling of lifting electric hoist, etc., the present invention proposes a belt-mounted type Beam cranes with corner trolleys to solve the problems and defects of traditional electric single-girder cranes
