Description
Technical field
The utility model relates to a kind of forklift parts, more specifically, it relates to a kind of AGV lift truck attachment.
Background technique
Lift truck attachment is also known as a variety of devices, is the tool for playing fork truck a tractor serves several purposes.With the development of economy, cost of land
Also in the rise of high speed, it requires and put more shelf on limited area as far as possible, minimize the width in channel,
Therefore the turning radius of warehousing forklift is required smaller.It addresses that need, fork truck manufacturing enterprise has developed fork truck three-dimensional category
Tool, this accessory can make 180 ° of shelf level rotations and left and right sidesway.It can not turn after fork truck installation three-dimensional accessory
In the case where have an ability that cargo is forked from side, realize that fork truck is carried and the ability of stacking cargo in arrow path.In addition, with
The high speed development of logistics, requirement of the loglstics enterprise for space utilization rate, the efficiency of loading and unloading is higher and higher, and manual operation has been got over
To be more difficult to adapt to new needs.In the new situation, fork truck manufacturing field also continues to introduce new, and wherein AGV fork truck pushes away
Out, handling operation efficiency and accuracy can be greatly improved.AGV fork truck is the programmable nothing of collection hydraulic pressure lifting and PLC control
The automatic guided vehicle of line scheduling, assists RFID identification as navigation mode using electromagnetic induction, can run on pahtfinder hard, more
The reliable tracking of website.Currently, there is no problem for the cargo of AGV carrying fork truck rule pile, but when carrying some special cargos, such as
Large-scale component section, complex device segmentation assembly etc., center of gravity of goods may bias, and force structure of such cargo on pallet fork is equal
Weighing apparatus property, stability are poor, once emergency stop or steering in the handling process, cargo are very likely toppled over, in this case between pallet fork
It needs to adjust to provide bigger supporting zone away from possible, and existing AGV fork truck intelligence degree is limited, cannot still be directed to center of gravity
The cargo of biasing carries out automatic corresponding adjustment, at this moment can ensure that AGV fork truck keeps efficient, smooth by necessary manual intervention
Operation.But existing fork truck upper fork is all that spacing adjustment is carried out by way of manually adjusting, if such adjustment mode
Applied to the AGV fork truck worked continuously, needing to stop is carrying out relevant operation, certainly will influence operating efficiency.Publication No.
The patent of invention of CN104442452B discloses a kind of unmanned electric railless three-dimensional stacking fork truck on April 5th, 2017, tool
