SU735529A1 - Tilter hoist - Google Patents

Description

The invention relates to lifting and transport machinery and can be used directly in CT hoHHO hoists mainly for unloading sapu. sludge cargo from a shaft furnace. operated with a fluidized bed in metallurgy during heat treatment of permanent magnets,

Known lift carousel type. hydraulically, comprising a frame carrying suspension baskets for goods 1.

The disadvantage of this device is the inability to rotate the basket.

. The closest technical solution is a hoisting / turning device for unloading bulk cargo containing a lifting device mounted on a support, equipped with a cargo basket and tilting device 2.

The disadvantage of this design is its low production: due to the impossibility of holding the basket by the neck, shocks and impacts of the basket, which leads to the deformation of its wall faces and the inconvenience of operating the device as a whole,

The object of the invention is to increase the productivity and usability of the hoist.

This is achieved by the fact that the hopper-lift device contains an Evans hinged-lever mechanism with

10 as a carrier and a rocker equipped with an arc for fastening the basket, and the tilting device comprises a loop hinged together with the basket on the arc, wherein

15, the rocker is equipped with a cam clutch equipped with a protrusion, and on the chain there is mounted a clip interacting with. coupling lug,

Fig, 1 shows a diagram of the rise of the 20 nick-kant.ovatel; Fig, 2-mufta; in fig. 3 - the position of the basket immersed in the bath. (Dotted line i indicates the tilted position of the basket); in fig. 4 - basket position at

25 bearing in it peuli; in FIG. 5, the position of the basket is close to horizontal.

Lift-tilter contains mast mounted on the foundation

with a tangential gap between the cams and the movable second coupling half with the cams 16 and the chain drive sprocket 17 connected by a chain 18 with the sprocket 8, Half coupling 15 and the chain drive are provided with a stopper containing a gear ledge 19 mounted on the half coupling and fixed on the chain 17 bracket 20 , The basket 12. upon loading, is lowered into the bath 21 provided with guides 22 for supporting the hinges and discharged into the bun Ker 23. The elevator tilter works as follows,

By means of a drive, the shaft 13 is turned into rotation in a clockwise direction, while the carrier is moved

6, the yoke 3 through the half coupling 15 asterisks 8, 16 and loop E, When the angle between the yoke 3, the carrier 6 is approximately 85 °, the loop abuts against the basket 12, there is no gap between the cam y in this direction. When the angle is between the root bar. 3 and the planet carrier 6 is approximately equal to 40 °; the loop will turn the basket from the vertical position by an angle

where 19/12 is the gear ratio of the chain drive,

When the carrier is turned further, the basket overturns into the hopper 23,

When lowering the basket back, the loop is retracted from the basket by chain transmission (Ivlyft is fixed one hundred

| sometimes) j If this is not done, the loop will be thrust into the oven and the mechanism will be stuck. The stopper is opened at the moment when the loop when the basket is lowered approaches the kouge from below. The loop is released and falls to the direction & 22 (so as not to capture the furnace side from below when lifting the basket)

When lifting the basket from the bath, 21 loops overtakes the basket and puts the clutch on the stopper. The loop rests on the basket when the bottom of the basket rises above the upper level of the furnace shaft. After this, the basket makes a translational motion along with the arc and rotates in a loop. At the same time, the neck goes beyond the hole, the bath is due to the use of a nonlinear trajectory of movement of the Evans mechanism,
