Novel efficient manual carrier and key parameter optimal selection method thereof

Abstract

The invention relates to the technical field of cargo carrying, in particular to a novel efficient manual carrier which comprises a carrier body, a lifting mechanism is arranged on the inner side of the carrier body, a set of adjustable pallet forks are arranged on one side of the lifting mechanism, a limiting locking mechanism is arranged between the carrier body and the lifting mechanism, and the carrier body comprises a chassis. A set of directional wheels are arranged at the front end of the chassis, and a set of universal wheels with brakes are arranged on the lower side of the rear end of the chassis. According to the novel efficient manual carrier, the lifting function is achieved based on the lever and crank sliding block principle, assistance and buffering are conducted through the gas spring, the lifting device is manufactured according to the proposed key parameter optimal selection method, lifting is rapid, and labor and power are saved; the cargoes only move up and down along with the pallet forks and keep parallel to the ground in the lifting process, the original postures of the cargoes are not changed, and extra space is not occupied; locking and unlocking control of the lifting position is integrated on the lower pedal, and single-person operation is facilitated. The whole machine is low in manufacturing cost, low in maintenance cost, efficient in operation, economical and practical.

Description

technical field [0001] The invention relates to the technical field of cargo handling, in particular to a novel high-efficiency manual transport vehicle and an optimal selection method for its key parameters. Background technique [0002] Pallet truck (pallet truck) can help people transfer heavy items to the desired location. It has a large carrying capacity, is easy to use, safe and reliable, and is widely used in daily life, as well as in warehousing logistics, engineering construction, landscaping and other industries. [0003] Traditional manual trucks often use hand-operated or foot-operated hydraulic lifts, which have slow lifting speed, high production cost, poor off-road capability, and poor reliability; simple rotary lifting trucks or hand-pulled luggage vehicles have simple structure and low lifting speed. Fast, but most of them are two-wheel structure. The wheels are connected with the rotating lifting mechanism. When carrying objects, it is necessary to apply a ...

Problems solved by technology

[0003] Traditional manual trucks often use hand-operated or foot-operated hydraulic lifts, which have slow lifting speed, high production cost, poor off-road capability, and poor reliability; simple rotary lifting trucks or hand-pulled luggage vehicles have simple structure and low lifting speed. Fast, but most of them are two-wheel structure. The wheels are connected with the rotating lifting mechanism. When carrying objects, it is necessary to apply a tilting force, which is inconvenient and laborious to use. It is especially not suitable for carrying objects with a low center of gravity and high mass. During the lifting process, the internal items rotate accordingly, the vibration amplitude is large, and it is easy to fall over and cause damage
