Follow-up walking accurate distance measuring and positioning device for four-way shuttle vehicle

Abstract

The invention discloses a follow-up walking accurate distance measurement positioning device for a four-way shuttle vehicle, which comprises a follow-up distance measurement wheel swing arm (3) movably arranged on a four-way shuttle vehicle body (1), one end of the follow-up distance measurement wheel swing arm (3) is movably fixed through a swing arm rotating shaft (4) fixedly arranged on the four-way shuttle vehicle body (1), and the other end of the follow-up distance measurement wheel swing arm (3) is movably fixed through a swing arm rotating shaft (5) fixedly arranged on the four-way shuttle vehicle body (1). One end of the follow-up distance measuring wheel swing arm (3) is provided with a swing arm rotating shaft (4), the follow-up distance measuring wheel swing arm (3) can freely rotate around the swing arm rotating shaft (4), the other end of the follow-up distance measuring wheel swing arm (3) is fixedly provided with a rotating shaft sleeve (18), and the follow-up distance measuring wheel (5) is fixedly arranged at one end of the follow-up distance measuring wheel rotating shaft (6) and is movably arranged in the rotating shaft sleeve (18) through the follow-up distance measuring wheel rotating shaft (6). The problem that positioning is inaccurate due to inaccurate distance measurement caused by deformation, abrasion, slipping and the like of walking wheels in the long-distance running process of the four-way shuttle vehicle is solved.

Description

technical field [0001] The invention relates to a follow-up walking precise positioning distance measuring device used by a four-way shuttle vehicle, belonging to the field of automatic three-dimensional storage and intelligent storage. Background technique [0002] The dense warehouse is produced to deal with the storage of large quantities of goods of the same kind. In order to make full use of the space in the dense warehouse, the shuttle car used to reload the goods in the dense warehouse is designed as a flat plate, also known as a shuttle or Shuttle board; and the four-way shuttle car is a handling equipment used in the three-dimensional storage system for cargo handling in the automated intensive storage warehouse, where the shelves can walk along the rails set vertically or along the tracks set horizontally. Usually, the collection warehouse is located in the longitudinal roadway where the goods are stacked, and the designed distance is longer; while the horizontal r...
