A power-assisted loading and unloading device for heavy and fragile express mail

Abstract

The invention relates to a power-assisted loading and unloading device for large, heavy and fragile parcels, comprising a mounting base, a conveying device arranged inside the mounting base, and a driving device connected with the conveying device. The conveying device comprises a first conveying section, a second conveying section and a third conveying section arranged inside the mounting base. The driving device comprises a pair of screws, motors arranged at the ends of the screws, a slider in threaded connection with the screws, and a pair of connecting rods hinged to the upper end of the slider. The connecting rods are arranged along a vertical plane, and the upper ends of the connecting rods are hinged to a cross bar below the second conveying section. The device has the advantage that the inclination angle of the second conveying section and the height of the third conveying section are changed by adjusting the inclination angle of the connecting rods, the inclination angle of the connecting rods can be adjusted just by changing the position of the bottom slider on the screws through forward / reverse rotation of the motors, the overall structure design is very reasonable, and adjustment is convenient.

Description

technical field [0001] The invention relates to an express loading and unloading device, in particular to a power-assisted loading and unloading device for heavy and fragile express delivery. Background technique [0002] In recent years, with the explosive growth of e-commerce, my country's express delivery industry has developed by leaps and bounds, and its business volume ranks third in the world. According to the survey, at present, my country's express delivery industry has problems such as untimely collection, slow delivery, and unenthusiastic service. It is urgent to improve in various aspects, among which the loading and unloading of large cargo is the top priority of improvement. [0003] Most of the traditional express mail loading and unloading devices adopt the conveyor belt type, and the height adjustment adopts the cylinder jacking device. However, because the traditional cylinders are all two-position cylinders, they can only stay at two extreme positions, res...

Problems solved by technology

[0003] Most of the traditional express mail loading and unloading devices adopt the conveyor belt type, and the height adjustment adopts the cylinder jacking device. However, because the traditional cylinders are all two-position cylinders, they can only stay at two extreme positions, resulting in the height of the device cannot be automatically adjusted. Application The scope is greatly reduced, so it is urgent to develop a power-assisted loading and unloading device for heavy and fragile express items with reasonable structural design, flexible height adjustment and wide application range. After searching, no technical solution identical or similar to the present invention has been found.
