Problems solved by technology

[0005] In view of the above problems, the present invention researches and designs a reinforced jib structure for jib cranes, which is used to solve the jib of existing jib cranes. During use, if the hanger is too heavy, it is often easy to It is broken and damaged, which affects people's normal use and cannot meet people's needs.

Abstract

The invention discloses a reinforced boom frame structure of a jib crane. A tripod is arranged at the bottom of a bottom knuckle boom, middle booms are arranged at the top of the bottom knuckle boom through connecting sheets, a plurality of middle booms are connected together by the connecting sheet, a top knuckle boom is arranged at the tail end of the last middle arm through the connecting sheet, and a support is formed at the front end of the top knuckle boom, and thus a frame body of the bottom knuckle boom, the middle booms and the top knuckle boom is formed; a square frame formed by outer rods is positioned at the outermost side, the about one-fourth position of the adjacent outer rod is connected and fixed by a reinforcing rod I, and one end of each reinforcing rod I is connected and fixed together with the farther end of the adjacent reinforcing rod I by a reinforcing rod II. According to the reinforced boom frame structure of the jib crane, when a heavy object is hoisted, the boom frame can be reinforced by the reinforcing rods I and the reinforcing rods II, so that breaking damage of the boom frame is avoided; and the reinforced boom frame structure of the jib crane is simple and novel in design, and is novel.

Description

technical field [0001] The invention relates to a reinforced jib structure of a jib crane. Background technique [0002] The characteristics of the jib crane are basically the same as those of the bridge crane. It can work in a circular field and above it, and is mostly used for open-air loading, unloading and installation. There are portal cranes, floating cranes, mast cranes, wall cranes and deck cranes. [0003] The jib crane includes: lifting mechanism, luffing mechanism and rotating mechanism. Relying on the coordinated actions of these mechanisms, heavy objects can be lifted and transported in a certain cylindrical space. Jib cranes are mostly installed on vehicles or other forms of transportation (mobile) tools, thus forming a running jib slewing crane. Such as truck cranes, tire cranes, tower cranes, portal cranes, floating cranes, railway cranes, etc. [0004] The jib of the existing jib crane is often broken and damaged if the hanging part is too heavy during u...
