The transmission principle of the electric stacker fork is that the motor transmits the power to the sprocket at the shaft end of the reducer through the coupling and the reducer, and the sprocket at the shaft end transmits the power to the drive shaft through the chain, and the sprocket on the drive shaft. As large as the sprocket at the shaft end of the reducer, the sprocket chain transmission ratio is 1. The gear installed on the shaft end of the stacker drive shaft transmits the power to the middle fork through the middle fork rack plate, so that the middle fork moves relative to the lower fork at a certain speed, and the double meshing gear installed on the middle fork connecting plate is in the middle. The speed of the fork moves together with the middle fork, the bottom of the double meshing gear meshes with the rack on the rack plate of the lower fork, and the upper side meshes with the rack on the rack plate of the upper fork, and the rack plate of the lower fork does not move, then the rack of the upper fork.The plate moves forward at twice the speed of the center fork.
When the electric forklift motor is reversed, the middle fork and the upper fork move in the opposite direction, thereby realizing the two-way access of the fork to the goods. The two-way baffle welded on the bottom plate of the lower fork of the electric forklift is used in conjunction with the two-way baffle welded on the bottom of the middle fork connecting plate. When the fork runs to the limit position, the upper and lower two-way baffles collide, so that the fork stops moving. . The coupling is a torque-limiting coupling. When the torque exceeds the set value, the steel ball inside the coupling slips, thereby protecting the fork from damage and improving the safety of the system.
The fork drive system of the electric stacker is basically symmetrical except that the motor, coupling and reducer are installed on the left side of the fork. The left half is equivalent to the left fork, and the right half is equivalent to the right fork. The chain drive is arranged in the middle of the fork, thereby improving the stability of the system.
