Manual pallet jack with power assisting device

Abstract

The invention discloses a manual pallet jack with a power assisting device. The manual pallet jack comprises two driving wheels (1), a handle (2), a pressing rod (4) hinged to the handle (2) and a driving mechanism capable of converting rotation actions of the handle (2) into rotation actions of the driving wheels (1) and is characterized in that the driving mechanism comprises inner ratchet wheels (3) fixed on the driving wheels (1) and capable of driving the driving wheels (1) to rotate, shifting rods (5) used for shifting the inner ratchet wheels (3), shifting forks (6) used for converting up-and-down actions of the pressing rod (4) into rotation actions and transmitting power to the shifting rods (5) and a control device used for controlling the shifting rods (5) and the inner ratchet wheels (3) to separate and match; a controller of the control device is arranged on the handle (2). The manual pallet jack with the power assisting device is simple to operate and high in reliability.

Description

technical field [0001] The invention relates to industrial equipment, in particular to a manual pallet truck provided with a booster device. Background technique [0002] With the rapid development of modern industry and logistics industry, manual hydraulic pallet trucks are widely used in warehouses, workshops, wharves and other places to carry items due to their small size, simple operation and convenient use. However, when the manual pallet truck is fully loaded on a flat road; in the case of a ramp; in the case of uneven ground or obstacles, it is more difficult for the operator to pull. According to the prior art, the State Intellectual Property Office discloses a light and small Industrial vehicles, the application number is 2013202602567, adopt the way of ratchet and pawl cooperation to realize the conversion of the rotation of the handle into the rotation of the drive wheel, and the engagement or disengagement between the pawl and the ratchet needs to be controlled b...
