Novel stand column type cantilever crane

Abstract

The invention relates to a novel stand column type cantilever crane which comprises a base. Universal sliding wheels and connecting plates are arranged on the base. Supporting legs are connected with the connecting plates. The base is connected with a stand column through a lifting bottom table and a lifting device. The stand column is provided with a motor fixing seat and a drive motor. The drive motor is connected with a fixing buckle A. The fixing buckle A is connected with a fixing buckle B through screw rods and nuts. The fixing buckle B is connected with a transverse rod which is connected with an inclined rod. The lower end of the inclined rod is provided with a longitudinal rod A, a longitudinal rod B, a longitudinal rod C and a longitudinal rod D. The longitudinal rod D is connected with a sliding rail and a sliding cable. The sliding cable is connected with a lifting hook through a steel wire rope. The lower end of the longitudinal rod D is connected with a cantilever beam. The cantilever beam is connected with an electric block and is connected with a connecting base through a connecting pillar. The connecting base is connected with a sliding block and an annular guide rail. A clamping hook is hinged to the connecting base, and an annular clamping rail is connected with the clamping hook. The novel stand column type cantilever crane has the beneficial effects of being reasonable in design, comprehensive in function, stable in structure, wide in use range, easy and convenient to operate and convenient to demount and mount.

Description

technical field [0001] The invention belongs to the technical field of hoisting machinery equipment, in particular to a cantilever crane, in particular to a novel column-type cantilever crane. Background technique [0002] In recent years, cranes have been widely used in machinery, construction and other industries. The cantilever crane is an arm with a pick-up device that is swivel on the end of the arm or on a lifting trolley that can run along the jib. The jib can rotate but cannot pitch. Frame type crane, which belongs to industrial parts, is a kind of crane with light working strength. It has the characteristics of light weight, large span, large lifting capacity, economical and durable, and is widely used in different fields of various industries. The columns of the crane are all fixed and non-movable structures, and they are not retractable. During operation, the position of the entire column-type cantilever crane cannot be moved, which limits the scope of use. The co...

[0002] In recent years, cranes have been widely used in machinery, construction and other industries. The cantilever crane is an arm with a pick-up device that is swivel on the end of the arm or on a lifting trolley that can run along the jib. The jib can rotate but cannot pitch. Frame type crane, which belongs to industrial parts, is a kind of crane with light working strength. It has the characteristics of light weight, large span, large lifting capacity, economical and durable, and is widely used in different fields of various industries. The columns of the crane are all fixed and non-movable structures, and they are not retractable. During operation, the position of the entire column-type cantilever crane cannot be moved, which limits the scope of use. The connection structure design of the cantilever and the column is not convenient for disassembly. The structural design of the cantilever is also relatively simple, so that the function is relatively single when used, not comprehensive enough, and there are certain defects. Therefore, a new type of cantilever with reasonable design, comprehensive functions, stable structure, wide range of use, simple operation, and easy disassembly and assembly is developed. Column jib crane is of great significance
