Description

The utility model relates to tilters, loading devices of cleaning equipment and can be used, in particular, in iron foundries for moving and loading castings weighing over 30 kg.

The utility model is designed to reduce the defectiveness of castings weighing over 30 kg due to chips and destruction when loading them into a tumbling drum.

The design of a device for tumbling is known according to RU patent for invention No. 2364488, priority dated November 29, 2007, containing loading and unloading devices installed on the frame, as well as a rotation drive connected to a tumbling drum of an original shape due to a multi-start screw column of at least one strip , bent along straight lines placed at an angle to the edges of the strip to form parallelograms located on the strip alternately in opposite directions. The strip is rolled into cylindrical turns, connected to each other along the longitudinal edges, forming unidirectional broken helical lines along the outer surface. On the outer and inner surfaces of the tumbling drum, helical broken pockets are formed in the form of geometric figures of a polygonal or curvilinear shape, while for polygonal-shaped pockets the distance between the straight fold lines of the strip is equal to the length of each element of the polygon, and for curved-shaped pockets - the length of its development, and the shape and the dimensions of the pockets on the inner surface of the tumbling drum are different from the shape and size of the pockets on its outer surface.

The design of a device for tumbling is known according to RU patent for invention No. 2094211, priority dated September 27, 1995, containing a working body mounted on the base from a conical outer and cylindrical inner shell with a rotation drive, while the outer shell is equipped with a larger diameter side located in the loading zone of workpieces plates-partitions and a section with annular perforation, under which there is a receiving container connected to a filter device, a pump and a pipeline with a spray funnel; on the side of the loading zone, a loading tray is installed in the inner shell, and at the opposite end of the unloading zone on this shell there is a ring perforated a groove in which a perforated ring with an internal radius groove is installed with the possibility of rotation.

Also known from the prior art is the design of a device for tumbling according to RU patent for invention No. 2478462, priority dated 10/13/2011, containing a tumbling drum placed on a frame by means of a frame with pneumatic cylinders, with means for loading and unloading parts, while the drum is barrel-shaped from sections mounted along the length in the form of various types of equilateral and unequal-sided trapezoids with the formation of square sections at the ends.

The closest analogue is the container device according to the application WO 2015031101 A1, B65D 6/02, 03/05/2015, made in the form of a frame with guides supported by opposite sides of the frame with a plurality of support element units passing between the tracks, as well as a movable door unit. The presence of a movable door assembly and many moving elements limits the use of this container due to the difficult loading of parts in a foundry environment and possible damage to the above-mentioned structural elements of the container by metal dimensional parts weighing over 35 kg.

A common disadvantage is that the above tumbling devices are designed for processing relatively small castings weighing less than 35 kg, so none of them are designed with a tilter.

The technical result of this utility model is to reduce the defectiveness of castings having a mass of 35-45 kg due to chips and fractures due to the development of a tilter design for loading castings of this mass into a tumbling drum.

The technical result is achieved due to the fact that the design of a casting tilter for loading into a tumbling drum is proposed on the basis of a container for moving castings, made in the form of a box-shaped body formed by an inseparably connected bottom, walls and load-bearing corner vertical posts; on the inner surfaces of the side walls there are clamps for holding pallets, reinforced on the opposite outer surfaces of the walls with stiffening ribs, while at the upper ends of the supporting corner vertical posts adjacent to the walls, and under the bottom of the tilter, gripping elements in the form of profile pipes are horizontally located, and to the lower edge of the bottom between two gripping elements and the supporting corner vertical posts are permanently installed with a jumper.

In a particular case, the gripping elements are made in the form of square pipes.

In a particular case, the clamps for holding the pallet are made in the form of U-shaped channels.

In a particular case, the bottom is connected to the walls through welded joints.

In a particular case, load-bearing corner vertical posts are permanently connected to the walls by means of welded joints.

The tilter design, made by permanently connecting the above parts, is obtained with increased rigidity and allows loading, in particular, passenger car cylinder block castings with a total weight of up to 1000 kg into the tumbling drum with a total weight of up to 1000 kg with a weight of each casting of 35-45 kg using a forklift.

The essence of the utility model is illustrated in Fig. 1, which shows a general view of the casting tilter for loading into the tumbling drum in axonometry (Fig. 1), consisting of a box-shaped body formed by the bottom 4, side walls 5, rear 6 with load-bearing corner vertical posts 8, with pallet clamps 3, in in a particular case, made in the form of U-shaped channels, they are permanently installed on the inner surfaces of the side walls 5, and stiffening ribs 7 are located on the opposite outer surfaces of the walls 5; elements for gripping 1 and 2, in a particular case made in the form of square pipes, are permanently attached to the upper ends of the load-bearing corner vertical posts adjacent to the walls 5, 6 and to the lower surface of the bottom 4 of the tilter, along the lower edge of which a jumper 9 is installed.

Research conducted using sources of patent and scientific and technical information has shown that the claimed design of a casting tilter for loading into a tumbling drum is unknown and does not clearly follow from the studied level of technology, that is, it meets the “novelty” criteria.

The proposed design of the tumbling drum tilter works as follows.

In foundry conditions, a prototype is used to load passenger car cylinder block castings with a total weight of up to 1000 kg into a tumbling drum, with a mass of each casting of 35-45 kg, consisting of a box-shaped body formed by the bottom 4, rear 6 and side walls 5 with load-bearing corner vertical racks 8.

A flat metal pallet with castings laid on it with a total weight of up to 1000 kg is driven by a forklift between the bottom 4 and the tumbling drum tilter clamps until it stops at the rear wall 6. After which the forklift, through the gripping elements 1, lifts the tumbling drum tilter with the castings and strings it through elements 2 on the forks of the tumbling drum. Then the tumbling drum rotates 180° and the castings from the tilter fall into its cleaning cavity, eliminating the fall from above of a flat metal pallet held in clamps 3. After which the tumbling drum turns back 180°, the forklift removes the tilter from the forks through the gripping elements 1 tumbling drum and lowers it to the floor, and then removes a flat metal pallet from the tilter to place a new batch of castings on it.
