An automatic container track hanging eight ropes on the shelf

Abstract

The invention discloses an automatic container rail hanging eight-rope upper shelf, which includes a shelf base, and the shelf base includes four beams, and a first guide rail, a moving plate capable of sliding along the first guide rail, and a first guide rail are arranged above each beam. The drive mechanism used to drive the moving plate on the beam to do linear motion. The top of each moving plate is provided with a lifting part, and each lifting part includes two separate turnbuckles and a lifting mechanism arranged on the top of each turnbuckle. Steel wire ropes, the bottom ends of each turnbuckle are connected with the moving plate, the tops of the two turnbuckles belonging to the same lifting part are connected by elastic ropes, and each lifting part is connected between two turnbuckles, two lifting wire ropes and an elastic rope. Cooperate to form an inverted A-shaped structure. The invention effectively alleviates the swing impact of the container and prolongs the service life of the steel wire rope.

Description

technical field [0001] The invention belongs to the field of anti-sway hangers of hoisting machinery, and in particular relates to an automatic eight-rope hoisting rack on rails for containers. Background technique [0002] During the crane handling operation, the large and small vehicles will generate acceleration and braking acceleration, which will cause the goods under the lifting point to shake, and the driver cannot immediately carry out the work of picking up and unloading the goods, thus prolonging the working cycle and reducing production efficiency. Therefore, how to anti-sway is a problem that all cranes must face. [0003] Anti-sway devices commonly used in cranes are divided into three categories: mechanical, hydraulic and electronic. The mechanical type refers to the use of mechanical principles to stabilize or anti-sway, which can be divided into two categories: rigid and flexible. There are mainly three types: rigid guide cylinder brake (rigid), separation t...

AI Technical Summary

Problems solved by technology

[0005] However, when the above-mentioned triangular eight-rope anti-sway structure is accelerated and decelerated by the crane operating mechanism, when the load swings, the steel wire rope will suddenly tighten, producing an instantaneous reaction force opposite to the swing direction. Due to the rigidity of the system, the steel wire rope often Withstand the instantaneous impact force, which will easily lead to wire breakage and shorten the service life of the wire rope
