Description

Technical Field

[0001] The utility model belongs to the field of mechanical equipment, and in particular relates to logistics loading mechanical equipment. Background Art

[0002] With the improvement of modern mechanization and the popularization of unmanned factories and smart factories, more and more companies are adopting automated storage, management and turnover of goods, which can improve space utilization and management efficiency and reduce labor costs.

[0003] For example, a loading mechanism disclosed in a prior patent (application number CN202321950191.9) includes: a movable bracket; a cargo display mechanism, which is movably arranged on the movable bracket and can move up and down, and one end of the lifting conveyor line is connected to the cargo display mechanism; a cargo display lifting drive component for driving the cargo display mechanism to move up and down, which is fixedly arranged on the movable bracket and is drive-connected to the cargo display mechanism; a lifting conveyor line for conveying goods, which is hinged to the cargo display mechanism at one end and hinged to the external structure at the other end.

[0004] However, with the specific application of the mobile loading platform, users have found that its structural design still has the following defects: when the cargo swing mechanism is movably set on the mobile bracket through the cargo swing lifting drive assembly, it is necessary to add lifting plates on the two side panels of the mobile bracket, and the cargo swing lifting drive assembly is fixed on the side panels and drives the lifting and lowering of the lifting plates, while the two sides of the cargo swing mechanism are respectively fixed to the two lifting plates, so that the cargo swing mechanism can stably lift and lower under the drive of the cargo swing lifting drive assembly on both sides; in order to enable the mobile bracket to smoothly enter the loading space such as the carriage for loading, the width size of the mobile bracket itself is limited. Therefore, under the premise that the width size of the mobile bracket is fixed, the width size of the cargo swing mechanism of the loading mechanism will undoubtedly be greatly reduced, affecting the size of the cargo that can be loaded.
