Problems solved by technology

[0005] Although it is generally believed that pallet jacks are a kind of mobile and flexible logistics handling vehicles, the existing pallet jacks are far from enough when they are empty.
Considering that more than 50% of the working time of the pallet truck is in the no-load condition, the defect of the excessively large turning radius of the pallet truck under the no-load condition brings a huge loss of efficiency to the user

Abstract

The invention discloses a tray truck with an auxiliary supporting wheel device. The tray truck comprises a common tray truck and the auxiliary supporting wheel device which is additionally arranged on the common tray truck, wherein the rear end of the common tray truck is provided with a steering wheel, the front end of the common tray truck is provided with a supporting wheel, and an original working wheel system of the common tray truck is formed by the steering wheel and the supporting wheel jointly; the auxiliary supporting wheel device is arranged at the bottom surface of a pallet fork of the common tray truck and is positioned in an appropriate position between the steering wheel and the supporting wheel, and a constraint condition that the self gravity center of the whole tray truck is located between an auxiliary supporting wheel and the steering wheel is met; under a no-load condition of the tray truck, the auxiliary supporting wheel has a supporting function by replacing the supporting wheel when the pallet fork drops to a lowest position, a new working wheel system is formed together by the auxiliary supporting wheel and the steering wheel, a new axle distance of the tray truck is formed by the distance between the auxiliary supporting wheel and an axis of the steering wheel, and the new axle distance is smaller than an original axle distance. According to the tray truck disclosed by the invention, the radius of turning circle of the tray truck under a no-load low-position working condition is reduced by changing the working wheel system and the axle distance of the tray truck under the no-load low-position working condition.

Description

technical field [0001] The invention relates to a pallet truck, in particular to a pallet truck with an auxiliary support wheel device. Background technique [0002] Current pallet trucks include manual pallet trucks, semi-electric pallet trucks, all-electric pallet trucks, etc., and their working wheel trains are composed of support wheels and steering wheels. The supporting wheel is installed at the front end of the fork, which is only used for bearing; the steering wheel is installed under the rear control arm, which has the functions of steering, driving and bearing. The steering wheel and the supporting wheel together constitute the working wheel train of the pallet truck; the distance between the steering wheel and the axis of the supporting wheel constitutes the wheelbase of the pallet truck. The turning radius of a pallet truck is determined by the length of its wheelbase. The longer the wheelbase, the larger the turning radius; the shorter the wheelbase, the sm...
