Intelligent physical distribution trolley driven by constant torque low-voltage direct current

Abstract

The invention relates to an intelligent physical distribution trolley driven by a constant torque low-voltage direct current. The intelligent physical distribution trolley comprises a support, a copper brush, a control board, a driver, an electromotor, a reduction box and a gear, wherein a power rubber wheel is installed on a driven shaft of the reduction box, four bearing wheels are installed below the four corners of the support, guide wheels are fixed to the axes of the bearing wheels, the guide wheels make contact with the side walls of tracks on the two sides, a fixed electronic tag recognizer is installed in the middle of the right side of the support, the driver is a low-voltage direct current servo driver, and the low-voltage direct current servo motor is of a non-carbon-brush structure. The intelligent physical distribution trolley effectively solves the problem that a traditional physical distribution trolley is small in load capacity, the low-voltage direct current servo motor can provide more constant torque than a low-voltage brushed direct current motor when the trolley climbs uphill, the output power and speed are ensured, the transmission efficiency is improved, dust pollution does not exist, and the intelligent physical distribution trolley has the advantages of being easy to maintain, low in noise and large in torque.

Description

technical field [0001] The invention relates to a logistics intelligent trolley, in particular to a high-power low-voltage DC constant-torque track trolley. Background technique [0002] The problem of the existing low-voltage brushed DC motor-driven logistics smart car is that when climbing and turning, the torque drops too fast after the resistance increases, resulting in insufficient output power and serious speed drop, which cannot meet the load and speed of hospital logistics transportation. fast demand. In addition, the carbon brushes of low-voltage brushed DC motors are consumables. They need to be replaced after three to six months of use, which is inconvenient for maintenance and pollutes the environment with dust. At present, there are many technical reports on logistics smart cars, but they cannot solve the above problems, such as: [0003] 1. The utility model with patent authorization announcement number CN201817069U discloses a rail transport trolley. The...
