Description

[Detailed Description of the Invention] This invention relates to a hoisting machine for a float-type dust remover installed on a cylinder gate that takes in surface water from a reservoir.

The dust remover that implements this idea has a dust removal screen such as a metal mesh installed between small floats that can be raised and lowered that are attached to multiple supports surrounding the cylinder gate, and the screen removes floating dust near the water surface. be.

In the case of such a float type dust remover, when the water level of the reservoir changes, the dust remover also moves up and down according to the water level.

Therefore, it is necessary for the hoisting machine of the dust remover to follow the lifting wire every time the water level changes.

This idea aims to solve the above problem, and involves wrapping the wire rope for lifting the float-type dust remover over the capstan of the hoist on the deck 4 to 5 times or more, and then attaching a weight to the other end of the wire. When a weight is attached and the water level rises and the dust remover rises, the weight descends, turning the capstan and winding up the rope on the dust remover side.When the clutch is engaged, the motor rotates the capstan. To provide a hoisting device capable of hoisting a dust remover.

Embodiments of this invention will be described in detail below with reference to the accompanying drawings.

In FIG. 1, reference numeral 1 denotes a dam constituting a reservoir, and a water intake tower B is provided inside the dam, and a cylinder gate main body A is provided inside the dam.

This cylinder gate main body A is made up of a plurality of sliding tubes 2 of different diameters fitted together to be extendable and retractable, and has a water intake port at its upper end.

Reference numeral 3 denotes an operation room on the water intake tower B, in which the cylinder gate main body A is lifted by a wire rope 4 hanging from a hoisting machine in this room 3, and a water intake port 5 is provided at the upper end of the gate main body A. It is.

Numeral 6 denotes columns provided at the four corners of the water intake tower B, and a large number of vertical rods 11 are fixed in parallel between the columns 6 at regular intervals to form a dust removal screen D.

E is a dust remover with a float placed outside the dust removal screen D, and 8 is its elevating frame.

This frame 8 is provided between the left and right floats 7 as shown in FIG. 2, and the floats 7 move up and down along guide rails 8' provided outside the water intake tower B.

As shown in FIG. 3, the rear part of a packet 9 is rotatably attached to the lower part of the lifting frame 8 by means of a shaft 10, and the packet 9 is made of a lattice-shaped frame covered with punched metal.

Furthermore, a dirt scraping claw 12 that fits between each vertical rod 11 of the screen D is attached to the rear of the packet 9 so as to be rotatable within a certain range.

Arms 13 facing rearward are fixed to both ends of each packet 9, and rollers 14 at the ends of the arms 13 contact the front surfaces of guide rails 15 fixed to both sides of the front surface of each screen D.

Reference numeral 15' in FIG. 3 is a movable locking lever rotatably attached to the side surface of the lifting frame 8 via a shaft 16. Below this lever 15', pins are attached to both ends of the packet 9 facing upward. 1
In addition, upper and lower stoppers are provided on the side of the lifting frame 8 to limit the upper and lower limits of the lever 15', and the tip of the lever 15' is provided with an engagement notch 18 that engages with the lever 15'. A float 21 is suspended via a connecting rod 20.

Reference numeral 22 indicates a pair of left and right wire ropes for hoisting the lifting frame 8, and F indicates a hoisting machine on a mounting base 31 located higher than the deck 23 provided in the water intake tower B.

The above hoist F has a motor 24, a reducer 25, and a pawl clutch 2.
6. Consisting of capstan 27, capstan 2
7 is attached to a rotating shaft 28 as shown in FIG. 2, and the rope 22 is wound around each of them, and a weight 29 is suspended from the other end of the rope 22.

This invention has the above-described structure, and the clutch 26 is normally disengaged with the lever 30 of the clutch 26 in the position shown by the solid line in FIG.

In this state, the float 7 of the dust remover E follows changes in the water level of the reservoir.

That is, when the water level rises and the lifting frame 8 rises, the weight 29 descends by that amount, and the rope 22 lowers the capstan 2.
7 rotates and the rope 22 on the lifting frame 8 side connects to the capstan 27.
It is wound up.

The opposite is true when the water level drops.

Further, normally, the elevating frame 8 is lowered, the packet 9 is located considerably below the position shown in FIG. 3, and the roller 14 is in contact with the vertical portion of the guide rail 15, so the packet 9 is oriented diagonally upward.

Further, since the float 21 is also in the water and is generating buoyancy, the lever 15' is also oriented diagonally upward.

To wind up the dust remover from this state, pull down the lever 30 as shown by the chain line in Figure 4 and start the motor 24 in the winding direction, and each capstan 27 will wind the dust remover side of each wire rope 22 in As the lifting frame 8 rises, the claw 1
2 rises while scraping away the dust between the vertical rods 11 of the screen D and falls into the diagonally upward facing packet 9. When the elevating frame 8 reaches its upper limit, the roller 14 moves to the upper end of the guide rail 15 as shown in FIG. The packet 9 enters the inclined part of the container 9, and the packet 9 is angled downward as shown in FIG. 3, and the garbage is discharged onto the deck 23.

Thereafter, when the motor 24 is reversed and the elevating frame 8 is returned to its original position, everything returns to its original state.

This invention is based on the rope 22 that winds up the dust remover E as described above.
is wrapped around the capstan 27 and its end is suspended, and a weight 29 is suspended from the lower end of the capstan 27.
By providing a clutch 26 between the shaft 28 and its drive motor, the float-equipped dust remover E always follows the water level of the reservoir when the clutch 26 is disengaged.

Further, since the rope 22 does not loosen due to the action of the weight 29, the dust remover E can be immediately hoisted up when the clutch 26 is engaged, making the operation of the dust remover E extremely easy.
