Description
Technical field
The present invention relates to a kind of piler more particularly to a kind of stacker fork automatic chain tensioning devices.
Background technique
Piler is a kind of storage facilities, refers generally to stakcer crane, seized with pallet fork or boom, carry and stacking or from
The special purpose crane of access unit cargo on High Level Rack.
Stacker fork chain stretching device is the important component of piler, and the quality of design directly determines stacking
The form of the stability and reliability of machine entirety, existing stacker fork chain stretching device is more, but generally all exists and account for
The shortcomings that intervention big with space and always artificial is adjusted.
Summary of the invention
The purpose of the present invention is to provide a kind of stacker fork automatic chain tensioning device, have occupy little space and
The characteristics of automatic adjustment, to solve the above problem existing for stacker fork chain stretching device in the prior art.
To achieve this purpose, the present invention adopts the following technical scheme:
A kind of stacker fork automatic chain tensioning device comprising chain fixing seat, first are without tooth sprocket, second anodontia
Sprocket wheel and backstand, wherein the chain fixing seat is fixed in interior fork plate, and described first is fixed on middle fork plate without tooth sprocket
On, described second is fixed in outer fork plate without tooth sprocket, and the backstand is fixed on mounting plate, and installs on the backstand
There is tensioning shaft, one end of the tensioning shaft is equipped with tensioning spring and locking nut, and the other end connects pallet fork chain, the pallet fork
The other end of chain sequentially passes through second and is connected in the chain fixing seat without tooth sprocket, first without tooth sprocket.
Particularly, on the mounting plate in the backstand and second without being provided with third between tooth sprocket without tooth sprocket,
The third is set on chain pulley seat without tooth sprocket, and the both ends of the chain pulley seat are fixed on mounting plate, and the pallet fork chain is certainly
Tensioning shaft introduces second without tooth sprocket without tooth sprocket through third.
Particularly, the tensioning spring uses die springs, and the locking nut is using the locking screw for having hexagonal flange
It is female.
Particularly, the both ends of the chain pulley seat offer mounting hole, lock onto mounting hole for chain pulley seat by bolt and nut
It is fixed on mounting plate, the mounting hole is the elongate holes of adjustable chain pulley seat installation site.
Beneficial effects of the present invention are that the stacker fork automatic chain tensioning device not only accounts for compared with prior art
It is small with space；And hardly need artificial tensioning.
