Technology status and Development trend of Stacking crane
1 Overview
Stacking crane is a special crane as of version of the warehou and developed to appearSpecial crane, commonly referred to as the pile of chop machine， piling machine is three-dimensional storehou of the most important lifting transportation equipment， reprents the sign of three—dimensional warehou characteristics. Its main u is：
In the top shelf of the warehou in orbit， will be located at the mouth of the goods in goods mesh; Or the opposite， take out loans in ca the goods to the mouth of roadway, the loading and unloading finish homework。 20 the early 70 s, China began to rearch the type of machine of roadway when the three—dimensional warehou, according to not complete count, up to now has been built more than three hundred ats。

tation equipment, also obtained fast development。
2 version of the prent situation of stacking crane technology.
According to the current machinery industry standard, the position of the stacking crane classification of ways. E.g. by supporting mode， u， the method of control， structure， operation such as classified track. But no matter what type of stacking machine， is general by the mobile mechanism， level of lifting mechanism， manifest Taiwan and goods fork institutions, frame and electrical equipment, and other basic parts。
In the prent application of three—dimensional warehou， stacking machine is the most common in the form of the structure and operation track classification。
2.1 version of the good way of spider crane structure From the structure form difference at prent in the warehou stacker has a double t on structure and single pillar structure。

2。1。1 double pillar stacker。
Double post the stacker frame structure by two root made on the beams, and to form a rectangle beam under the framework。 Pillar form well pipe and pipe。 Square tube and be lifting guide rail, pipe additional hoisting guide double pillar stacker the biggest advantage is the strength and the brush x are quite good, and smooth operation. General for lifting height， weight and higher up large speed high level of three—dimensional storehou stacker, many with double pillar structure， double pillar stackers lifting mechanism, widespread u of the chain transmission， by motor reducer drive sprockets rotation， through the chain traction machine parts made on or along the hoisting guide for lifting movement。 Due to the chain transmission ud more clod chain or balance by empty asked size limit device, transmission and decorate a complicated。 But positioning precision.
2。1。2 single pillar stacker.
Single pillar of stacker frame structure by a root of the pillar and beam。 Pillar ud more
larger h—beam or welding production, pillar additional guide。 The weight of the lighter， consume little material, so manufacturing relatively low cost， but the rigid is a bit poor. Becau parts of Taiwan and the goods on the eccentricity of the opposite effect, and walk, the braking force level from the effect， make single pillar stacker in ud on have limitations。 Not suitable for lifting weight and the running speed of the high level of stacking machine。 Single pillar stackers hoisting structure, the widespread u of the wire rope transmission, by motor reducer drive drum rotating, through the wire rope traction machine parts made on or along the lifting rails for lifting movement。 For wire rope transmission， transmission and decorate relatively easy， but positioning accuracy is a bit poor.捡烂纸的老头

Version 2。2 of stacking crane to track the performance Stacker level drive general installation in stacker next beam, through the electricity
Machine speed reducer drive wheel rotation， make stacker level concerning the direction. This ground driving way most common u。 General u two bearing wheel，
and along the laying on the ground track (usually also called to rail） operation. Through the bottom two groups of level round orbit direction， the top two groups剪刀怎么画
in stacker guide wheel along in orbit （usually also called day rail) operation auxiliary oriented. According to the running track form difference， there is a straight line type stacker and curve operation type stacking machine。
2.2. L straight lines type stacking machine。

Straight line type stacker can only be in the roadway straight orbit， unable to convert roadways. Only through the other transportation equipment of transformation, such as stacker car transport. Straight line type stacker can realize the operation, and can satisfy the loading and unloading higher frequency three-dimensional storehou homework， most widely ud。
