Abstract
The invention discloses an overload protection device for a fork of a stocker. The overload protection device comprises a fork driving shaft, wherein a duplex chain wheel is arranged on the fork driving shaft, and is connected with a driving motor through a driving chain; the overload protection device is characterized in that a friction clutch capable of setting an output torque is arranged on the duplex chain wheel. According to the overload protection device for the fork of the stocker, the friction clutch is additionally arranged on the fork driving shaft, so that if the fork of the stocker collides a shelf, the set torque is exceeded; the duplex chain wheel slides relative to the fork driving shaft, so that the overload protection function is realized. The occurrence of accidents is prevented, and the overall security of the stocker is improved.
Description
Technical field
The present invention relates to a kind of stacker fork, particularly relate to a kind of overload protection device for stacker fork.
Background technology
At present, the actuating device being conventionally used to the pallet fork of piler adopts motor direct-drive pallet fork, and pallet fork is in tiered warehouse facility during operation, be in automatic job, electric malfunctioning time pallet fork stretch fork picking time knock shelf after, serious accident may be there is, cause larger loss.
Summary of the invention
The object of the present invention is to provide a kind of overload protection device for stacker fork, it plays safety guard-safeguard effect after can knocking shelf to stacker fork, avoids the generation of accident, to solve the problems referred to above that in prior art, stacker fork exists.
For reaching this object, the present invention by the following technical solutions:
A kind of overload protection device for stacker fork; it comprises pallet fork axle drive shaft, and described pallet fork axle drive shaft is provided with duplex chain wheel, and described duplex chain wheel connects drive motor by chain drive-belt; wherein, described duplex chain wheel is provided with the friction clutch that can arrange output torque.
Especially, described friction clutch comprises friction lining, T-shape cover, catch, elastomeric element, pad and nut, described T-shape cover fixed cover is loaded on described pallet fork axle drive shaft, it is disposed with duplex chain wheel, catch, elastomeric element, pad and nut, the two side of described duplex chain wheel is provided with friction lining, wherein the friction lining of side and described T-shape overlap the contact internal walls of head, the friction lining of opposite side contacts with described catch, and described T-shape cover afterbody is provided with external thread section, described nut is assemblied on described external thread section.
