A hand-push cargo truck

Abstract

The invention provides a hand-push goods van and relates to the technical field of goods loading and unloading equipment.Shear mode connecting rod mechanisms are symmetrically arranged on the left side and the right side of a bottom plate of a trolley frame.Cylinder pins matched with sliding grooves in the two sides below a lifting slab are arranged at one ends of the upper portions of two sets of connecting rods of the shear mode connecting rod mechanisms.Through holes are formed in one ends of the lower portions of the connecting rods of the shear mode connecting rod mechanisms.The connecting rods at the two sides are sleeved with the two ends of a synchronous shaft respectively through the through holes.A first pulley is fixedly connected to one end of the synchronous shaft.One end of a steel wire rope is fixedly connected to the front end of the trolley frame, and the other end of the steel wire rope is fixedly connected with a disk through the first pulley, a second pulley, a third pulley and a self-locking device.The disk is connected with a hand rail at the rear end of the trolley frame through pins.A one-way clutch is arranged on one side of the disk and connected with a belt wheel through a belt.The belt wheel is connected with an axle through a flat key.One ends of the connecting rods are in eccentric connection with the disk through cylinder pins.The other ends of the connecting rods are connected with pedals through cylinder pins.The hand-push goods van is mainly used for carrying goods within a short distance.

Description

technical field [0001] The invention relates to the technical field of cargo handling equipment. Background technique [0002] In order to facilitate the transportation and handling of express items, many mechanisms or devices already exist. At present, the intelligent terminal self-lifting container system has experienced explosive growth, GPS equipment locomotive networking technology has made great progress, drone distribution technology has made breakthroughs, fully automated automatic sorting systems are showing rapid growth, and some new technologies and products are constantly emerging. Information technologies such as computing, Internet of Things, big data, and mobile Internet have had a huge impact on the logistics industry. And existing goods handling vehicle generally adopts the lowest steel frame handcart and utilizes the handcart of hydraulic pressure or motor control lifting. The former mechanism is very labor-intensive in the express handling process. Alth...

AI Technical Summary

Problems solved by technology

The former mechanism is very labor-intensive in the process of express handling

Although the latter can use external force and other energy sources to control the lifting of goods, they all have defects: high manufacturing precision and technical requirements for components, and difficult assembly

Furthermore, its accuracy is difficult to control and the hydraulic transmission is very expensive and difficult to repair

Although the second type of electric pallet truck is accurate, it is too expensive and consumes a lot of energy for express delivery
