Description

Widen stable piler

Technical field

It is the present invention relates to storage field, in particular to a kind of to widen stable piler.

Background technique

Storied 3-D Automatic Warehouse is the indispensable ring in logistic industry, it is not need manually to be done The automated system of cargo is consciously stored and taken out in the case where pre-, it is that the high-tech that modernization industry society is expedited the emergence of produces Object, and piler is lifting decoding apparatus mostly important in storied 3-D warehouse.

Currently, the pallet fork of most pilers is flexible for single-stage, length dimension be cannot be adjusted, and limit the stroke for picking and placing material Range；Or be set as multi-stage expansion, stroke is amplified, greatly improve pick and place material stroke range, but not only every grade all need Individually driving power source is configured, and belongs between every grade and is operated alone, cannot carry out, take a long time simultaneously, Efficiency is lower, and it is weak to carry weight ability, since pallet fork needs to stretch out relatively long distance from loading platform, in reply heavy duty and When more depth position storages, it is more difficult to solve the contradiction between outreach, goods weight and fork dimensions, be easy to cause the end of pallet fork Since lever principle bears excessive torque, causes the weight of access cargo to be restricted, influence use reliability；Piler Elevating mechanism mostly uses single-column lifting structure, has the shortcomings that gravity center instability, balance are bad.Therefore, there is stronger cargo Bearing capacity, preferable promotion support force and preferable stability of equilibrium, extensive, the low energy consumption of automatic access material from shelf It is extremely urgent with the piler of long stroke pallet fork.

Summary of the invention

In order to solve the above technical problems, the present invention provide it is a kind of widen stable piler, taken with solving existing piler The stroke range for putting material is small, carrying weight ability is weak and lifting process in gravity center instability, the problems such as balance is bad.

The technical solution adopted by the invention is as follows: a kind of widen stable piler, including pedestal, set vertically on the pedestal There is portal frame, lifting device be installed on the portal frame, key is: scalable pallet fork is installed on the lifting device, The lifting device drives the scalable pallet fork along the short transverse vertical motion of the portal frame；

The scalable pallet fork includes two horizontally disposed crotch, is equipped with Synchronous Transmission group between two crotch Part is equipped with fork body on the crotch, fork body transmission component is equipped in the crotch, and the fork body passes through the fork body transmission group Part is slidably connected with the crotch, and the fork body transmission component includes at least two driving gears and driven rack gear, two neighboring The first pinion, the driving gear and the engagement of the first pinion, the driving gear and the are equipped between the driving gear One pinion is solidly set on driving shaft and countershaft respectively, the both ends of the driving shaft and countershaft two sidewalls with the crotch respectively Bearing connection, the fork body are fixedly connected with the driven rack gear, and the driven rack gear is engaged with the driving gear drives institute The length direction level that fork body is stated along the crotch is slided.

The beneficial effect of above scheme is to can guarantee there are enough stability of strutting system to lifting device using gantry frame structure, Up and down balance system is improved, two fork bodies of pallet fork can be moved by Synchronous Transmission component, while relative to crotch bi-directional expansion, Easily the material on the shelf of two sides is accessed, improves load-bearing capacity of the pallet fork when picking and placing material, and multiple Under driving gear drives, body horizontal sliding on crotch is pitched, stability of material during storage is improved, increases pick-and-place The stroke range of material.

Preferably, the Synchronous Transmission component includes the axis mounting base of two faces setting, water between two axis mounting bases Flat to be equipped with the same universal driving shaft, two axis mounting bases are arranged respectively close to two crotch, the top of the axis mounting base Be fixedly connected with the lower part of the close crotch, be installed with two synchromesh gears on the universal driving shaft, the synchromesh gear with most The second pinion is equipped between the close driving gear, the synchromesh gear and the second pinion are separately mounted to close institute It states in axis mounting base, which engages with the synchromesh gear and the driving gear respectively, and the universal driving shaft is appointed One end is pierced by the linkage pedestal and is connected with driving device.

The effect of the program is that single driving device drives two synchromesh gears on same universal driving shaft to rotate, to drive Driving gear rotation, and then two fork bodies is driven to synchronize movement, it is compact-sized, it does not need separately to be operated alone, improves work Make efficiency and running precision.

Preferably, the driving device includes driving motor, is installed with drive sprocket on the output shaft of the driving motor, The either end of the universal driving shaft is installed with driven sprocket after being pierced by the axis mounting base, covers on the drive sprocket and driven sprocket Equipped with the same chain.

The effect of the program is driving motor by the driven sprocket on driving universal driving shaft, realizes the rotation of universal driving shaft, from And complete the synchronizing moving of two fork bodies.

Preferably, the fork body includes the upper fork body and lower fork body of upper and lower face setting, the upper fork body and the lower fork Body is slidably connected, and is fixedly connected with the driven rack gear, upper ipsilateral point for pitching body and lower fork body with the lower surface of the lower fork body Not She You the same limit stop assembly, two limit stop assemblies are diagonally arranged.
