The track 2 comprises an annular track main body 21 matched with an annular production line, N linear tracks 22 correspondingly arranged above the N rows of pickling tanks 3, and two groups of translation turnouts 23 respectively arranged at the inlet and the outlet of the pickling tank 3 and used for communicating the annular track main body 21 with the linear tracks 22. The two sets of translating switches 23 are front translating switch 231 and rear translating switch 232, respectively.

As shown in fig. 3 and 4, each set of translation switches 23 includes an electric screw 233, a bracket 234, and N steel rails 235 arranged below the bracket 233 in the same number as the number of the linear rails 22.

A pulley 236 is arranged above the bracket 233, a slide rail 237 for the pulley 236 to run is arranged above the production workshop, and the bracket 234 is hung above the production workshop through the matching of the pulley 236 and the slide rail 237. The bracket 234 is fixedly connected to one end of the electric screw 233, and horizontally moves relative to the slide rail 237 under the driving of the electric screw 233 to switch the steel rail 235 and conduct different linear rails 22.

The steel rails 235 comprise at most one straight steel rail and at least N-1 arc steel rails, and the steel rails 235 are arranged in an axisymmetric mode. The distance between the two adjacent steel rails 235 and the end close to the linear track 22 is greater than the distance between the two adjacent linear tracks 22, and the distance difference is equal to the distance between the two adjacent steel rails 235 and the end close to the circular track main body 21.

When the electric hoist 1 fully loaded with the workpiece travels to the forward translation turnout 231 along the circular rail main body 21M, the central control system can automatically identify the number of workpieces and the pickling time in each existing pickling tank 3, and automatically determine the pickling tank 3 to which the next electric hoist 1 loaded with the workpiece needs to go.

As shown in fig. 5, when it is recognized that the empty pickling bath 3 is left in the pickling line below the linear rail 22A, the bracket 234 is controlled by the electric screw 233 to move horizontally so that both ends of the rail 235a1 overlap the ring rail body 21M and the linear rail 22A, respectively, and the linear rail 22A is conducted.
