Description

This invention relates to machines for cleaning hydraulic grids with drums for raising and lowering a rake. A feature of the described machine is the switching of the rake to the working and non-working position with the help of an electric motor, by means of which the lifting (extreme) drums are driven.

FIG. 1 and 2 shows a machine in two projections; in fig. 3, 4 and 5 - details of the device rake.

The machine consists of an electric motor /, gearboxes 2 to 3, belt brakes 4, drums 5 and 5 with cables and rakes 7.

The motor /, gearboxes 2 ' 3, belt brakes 4 and the drums 5 and 6 are mounted on one of the reservoir tanks of the pressure pool and through the shaft system serve all the spans in which the rake 7 is placed.

The included electric motor rotates the drive shaft 8 through the gearboxes during the entire course of the cleaning operation of all the spans of the grids. The worm gear of the drum drive shaft gear is rigidly connected to the drum switching rake, the sleeve with the notch, and the drive shaft of the lifting drums passing through this sleeve is provided with a finger located in the cut of the sleeve and intended to transmit rotation to the shaft from the sleeve after turning rake to the working position or to the lowering position.

To put the rake 7 into operation when lowering, it is necessary to squeeze the handle lock out of the socket by pressing the lever sitting on the handle and turn the handle in the appropriate direction, together with which the lever acting on the lock is loosened. The correctness of the inclusion of the rake is controlled by a special mechanism.

The extreme drums 5 serve to move the rake 7 vertically, and the middle 6 to rotate them from working position to idle and vice versa.

No. 81091-2 Grade 7 HMetOT, 9 (Fig. 3-5) at the ends. At the approach of the rollers to the extreme - {even position, they act on the available automatic slot 10 (Fig. 2) and the rakes stop.

When the troubles are in the upper extreme position, the worker sweeps them away. the garbage then turns on the handle of the mechanism for a working stroke and the operation is repeated in the same sequence.

When the rake is moving up or down at a distance of 10 m, the cleaning process of the grids is closed: it takes about 12 minutes at an average speed of movement of the rake, about 2 m in, chickpeas.

Subject invention

A machine for cleaning hydraulic grids, in which drums are used for raising and lowering the cleaning rake and a drum for switching the rake to the working or non-working position, characterized in that for automatic switching of the rake when they are raised and lowered using an electric motor that moves the rake along the grid , the worm gear of the drum drive shaft gearbox has a sleeve with cut-out rigidly connected to the rake switching drum, and the drive shaft of the lifting drums passing through This sleeve is provided with an Alzam, located in the cutout of the sleeve and intended to transmit rotation to the shaft from the sleeve after the rake is rotated to the working position or to the lower position.
