The telescopic end of the telescopic rod is fixedly connected with one end of the L-shaped shift rod, the lower end of the shift rod extends to the inside of the shift slot, and a gap is reserved between the shift rod and the inner wall of the shift slot.

Further, the second connecting sleeve is slidably matched with the second rotating shaft through a guiding flat key.

Further, the top of the installation box is fixedly provided with installation ears.

Compared with the prior art, the beneficial technical effects of the present utility model:

The utility model can not only lift a single cargo like a normal single-drum electric hoist, but also realize the connection between the second rotating shaft and the first rotating shaft through the claw-type cooperation between the second connecting sleeve and the first connecting sleeve. Therefore, the driving motor can drive the two reels to rotate synchronously to lift the two goods, which significantly improves the work efficiency when carrying out the lifting operation of more goods.

Detailed ways

As shown in Figures 1-2, a new type of double drum electric hoist includes an installation box 1, the top of the installation box 1 is fixedly provided with installation ears 16, and the installation box is installed on the crane through the installation ears 16 Or hang the gantry.

A drive motor 2 is installed on one side of the installation box 1 , and two connecting plates 3 are symmetrically fixed inside the installation box 1 . A first rotating shaft 4 and a second rotating shaft 5 are respectively rotatably installed between the two side walls of the installation box 1 and the two connecting plates 3 . The outer sides of the first rotating shaft 4 and the second rotating shaft 5 are fixedly installed with reels 6, each of the reels 6 is wound with a hoisting cable 7, and the lower end of each of the hoisting cables 7 penetrates through the The installation box 1 is described and a hook 17 is installed.

The drive shaft of the drive motor 2 is connected with one end of the first rotating shaft 4 , and the other end of the first rotating shaft 4 penetrates the connecting plate 3 on the corresponding side thereof and is fixedly installed with a first connecting sleeve 8 . The outer circumference of the free end of a connecting sleeve 8 is evenly provided with first teeth 9 .

One end of the second rotating shaft 5 close to the first rotating shaft 4 passes through the connecting plate 3 on the corresponding side thereof and is slidably installed with a second connecting sleeve 10 , and the second connecting sleeve 10 is connected to the second connecting sleeve 10 through a guiding flat key 15 . The rotating shaft 5 is slidably fitted, and the outer periphery of the free end of the second connecting sleeve 10 is evenly provided with second teeth 11 which are fitted with the first teeth 9 . The middle part of the second connecting sleeve 10 is provided with a dial slot 12, one of the connecting plates 3 is installed with an electric telescopic rod 13 along the horizontal direction, and the telescopic end of the electric telescopic rod 13 is connected to the L-shaped dial rod 14.
