Abstract

The invention discloses an automatic tensioning device of a stocker fork chain. The automatic tensioning device of the stocker fork chain comprises a chain fixing base, a first toothless chain wheel, a second toothless chain wheel and a tensioning base, wherein the chain fixing base is fixed to an inner fork board; the first toothless chain wheel is fixed to a middle fork board; the second toothless chain wheel is fixed to an outer fork board; the tensioning base is fixed to an installation board and provided with a tensioning shaft; one end of the tensioning shaft is provided with a tensioning spring and a locking nut; the other end of the tensioning shaft is connected with the fork chain; the other end of the fork chain sequentially penetrates through the second toothless chain wheel and the first toothless chain wheel and is connected to the chain fixing base. The automatic tensioning device of the stocker fork chain not only is small in occupied space, but also almost does not need manual tensioning.

Description

A kind of stacker fork automatic chain tensioning device
Technical field
The present invention relates to a kind of piler, particularly relate to a kind of stacker fork automatic chain tensioning device.
Background technology
Piler is a kind of storage facilities, refers generally to stakcer crane, seizes with pallet fork or boom, carries and stacking or the special purpose crane from access unit goods High Level Rack.
Stacker fork chain stretching device is the important component part of piler, the quality of its design directly determines stability and the reliability of piler entirety, the form of existing stacker fork chain stretching device is more, but generally all exist and take up room greatly, and dry preregulated shortcoming artificial always.
Summary of the invention
The object of the present invention is to provide a kind of stacker fork automatic chain tensioning device, it has the feature of the little and automatic adjustment that takes up room, to solve the problems referred to above that in prior art, stacker fork chain stretching device exists.
For reaching this object, the present invention by the following technical solutions:
A kind of stacker fork automatic chain tensioning device, it comprises chain permanent seat, first without toothed chain wheel, second without toothed chain wheel and backstand, wherein, described chain permanent seat is fixed on interior fork plate, described first is fixed on middle fork plate without toothed chain wheel, described second is fixed on outer fork plate without toothed chain wheel, described backstand is fixed on adapter plate, and described backstand is provided with tensioning shaft, one end of described tensioning shaft is provided with tensioning spring and jam nut, the other end connects pallet fork chain, the other end of described pallet fork chain passes second successively without toothed chain wheel, first is connected on described chain permanent seat without toothed chain wheel.
Especially, described adapter plate is provided with between described backstand and second is without toothed chain wheel the 3rd without toothed chain wheel, described 3rd is arranged on chain pulley seat without toothed chain wheel, the two ends of described chain pulley seat are fixed on adapter plate, and described pallet fork chain introduces second without toothed chain wheel through the 3rd without toothed chain wheel from tensioning shaft.
Especially, described tensioning spring adopts die springs, and described jam nut adopts the jam nut of tool hexagonal flange.
Especially, the two ends of described chain pulley seat offer mounting hole, lock onto mounting hole be fixed on adapter plate by chain pulley seat by bolt and nut, and described mounting hole is the elongate holes of adjustable chain pulley seat installation site.
Beneficial effect of the present invention is, compared with prior art described stacker fork automatic chain tensioning device not only takes up room little; And need artificial tensioning hardly.
