Trolley capable of lowering labor intensity of waist and using method thereof

Abstract

The invention relates to a trolley capable of lowering the labor intensity of the waist and a using method of the trolley. The trolley comprises a frame. A bearing table is connected to guide rails on the frame in a sliding manner, an air pump is fixedly arranged at the lower end of the frame and connected with power supply equipment on the frame, the air pump is connected with an air storage tank through a pipe, the air storage tank is connected with an air cylinder and air through a pipeline, one-way valves are arranged in the pipe and the pipeline, an air cylinder push rod is arranged at the lower part of the air cylinder, a stretching spring is arranged between the air cylinder push rod and the bottom of the frame; a first chain wheel, a second chain wheel, a third chain wheel and a fourth chain wheel are arranged between the bearing table and the air cylinder push rod, the second chain wheel and the third chain wheel are coaxially connected, a first chain is erected on the first chain wheel and the second chain wheel, a second chain is erected on the third chain wheel and the fourth chain wheel, the side, close to the bearing table, of the first chain is fixedly connected with the bearing table, and the side, close to the air cylinder push rod, of the second chain is fixedly connected with the air cylinder push rod. The trolley has the beneficial effects that the trolley can adapt to goods with different mass through the change in atmospheric pressure, the frequency of bending down in the handling process is reduced, and the labor intensity of the waist is lowered.

Description

Technical field: [0001] The invention relates to the technical field of transportation tools, in particular to a trolley capable of reducing the labor intensity of the waist and a use method thereof. Background technique: [0002] As we all know, in the process of logistics transportation, trolleys play an indispensable role. At present, most of the handcarts popular in the market are handcarts with the most basic functions, which cannot effectively reduce the redundant labor consumption of the waist caused by the multiple bending of relevant personnel when loading or unloading goods. [0003] It is a development trend of the trolley to make the trolley lightweight, convenient and meet the requirements of ergonomics. [0004] The Chinese patent with the application number 201320453526.6 discloses a groove-shaped car body formed by using the bottom plate and the two side plates to reduce the use of manpower when the geotechnical coil is transported. But it does not take int...

Problems solved by technology

However, the device has a complex structure and cannot be adapted to objects of various weight ranges.

[0007] Looking at the existing devices, most of the trolleys have not been widely used in daily life or delivery sites, either because of their high cost, or because of their complex structure, or because they only function in specific fields.
