Description

The crane cranes currently used, mainly designed for heavy loads, such as trolley frames, traction engines, wheel sets of electric locomotives and diesel locomotives, are made in the form of rocker arms with their ends bent down and equipped with hydraulic actuators.

The described crane turner differs from the known ones in that the rod of the power cylinder reinforced in the rocker arm is made integral with the lifting eye, and on the bent ends of the rocker arm the single-acting hydraulic cylinders are mounted, each of which is equipped with two pistons rigidly connected to each other by a rack. The latter interacts with the load turning gear while the pistons are moving. Crane turner of this design provides the rotation of the load under its own weight.

FIG. Figure 1 shows schematically the described tilter in two projections; in fig. 2 - diagram of the hydraulic drive.

The tilter is suspended on the hook of the crane for lifting eye 7, made integral with the rod 2 of the hydraulic power cylinder 3 located in the rocker arm 4. At the bent end of the rocker arm a hydraulic device 5 is rotated, on the shaft of which the gripping device 6 is mounted.

Kantovate; by means of a crane, it is lowered onto the product, connected to it with the help of clamps 7, and raised above the floor to the required height. In this case, the spool 8 is in the middle position and closes all the pipes connected to it.

The oil in the upper cavity of the cylinder 3 is under pressure, the value of which depends on the weight of the turning device with the product. With re # 151784

Turning the spool 8 to the extreme position (in the diagram to the left), the oil from the upper cavity of the pump cylinder goes through pipes 9 to 10 into the hydraulic cylinder 11 of the turning device 5 and moves the piston 12 to the left. The piston 12 through the gear rail 13 Brush, drives the gear 14, which is seated on the shaft, and consequently, the gripping device 6 together with the product.

The speed of rotation is limited by the throttles 15 and 16. As oil flows from the upper cavity of the power cylinder 3, the entire system descends somewhat. After the product is rotated to the desired angle, the spool overlaps and the tilter with the product is lowered to the floor.

The piston of the power cylinder under its own weight moves downward and from the tank 17 through the check valve 18 it sucks in oil, instead of consumed.

Subject invention

Crane turner, mainly for heavy loads, such as truck frames, diesel locomotives and others, consisting of a rocker arm with bent down ends and a hydraulic actuator, characterized in that, in order to achieve load rotation under the action of its own weight, the rocker is equipped with a power hydraulic cylinder, rod which is made at the same time with a lifting eye, and at the bent ends are mounted hydraulic devices, each of which is made in the form of a single-acting hydraulic cylinder with two pistons rigidly fixed between second rack means cooperating with the pistons move under the action of power cylinder with the pinion rotation load.
