Portable loading, unloading and transferring integrated obstacle-surmounting trolley

Abstract

The invention discloses a portable loading, unloading and transferring integrated obstacle-surmounting trolley. The portable loading, unloading and transferring integrated obstacle-surmounting trolley comprises an upper trolley frame, a lower trolley frame, an electric push rod jacking unit, a lead screw sliding block lifting unit for obstacle surmounting, a variable power transmission unit and a power differential steering unit. The electric push rod jacking unit comprises an upper push rod, a lower push rod and two air springs. The lead screw sliding block lifting unit comprises a lead screw and a gear motor. The variable power transmission unit comprises an installation base plate, a pulling rope, a driving chain wheel, a transmission shaft, a first bevel gear, a second bevel gear, a tooth-embedded clutch, a transmission shaft chain wheel, a wire-controlled shifting block and a guide rail. Under the effect of the driving chain wheel, the transmission shaft drives the tooth-embedded clutch to rotate, an operator controls the pulling rope to make the tooth-embedded clutch be engaged with the first bevel gear and the transmission shaft chain wheel correspondingly under different working conditions, and transmission of power in different directions or on different components is achieved; and the power differential steering unit comprises outer hubs, wheels, one-way bearings, inner hubs, an axle and a chain wheel.

Description

technical field [0001] The invention relates to a portable loading, unloading and transporting integrated obstacle-crossing trolley, which belongs to the field of carrying booster devices. Background technique [0002] In recent years, with the sudden emergence of e-commerce, online shopping has become an indispensable part of people's lives. However, the loading and unloading of heavy goods in the current express logistics terminal and the transportation under complex terrain basically rely on the combination of human handling and small flatbed trucks for transportation. There is no portable mechanical device capable of loading and unloading goods under complex terrain conditions, which leads to high terminal delivery costs for less-than-truckload express and light logistics, and high prices for heavy-duty express logistics. [0003] On the other hand, the development of the economy has led to rising labor costs, cheap labor is not as readily available as in the past, and ...
