Description

A hydraulic rotary crane for loading pasta of paint-grinding machines with dvzm piston cylinders, made in the form of a stand and a rotary boom with a console, is known. Cranes of this type usually have a separate area, on which cylinders, actuators and other auxiliary units are mounted vertically, which makes these cranes somewhat cumbersome and does not allow them to be used for servicing spray guns.

The peculiarity of the described hydraulic crane is that, in order to give it a more compact form and the possibility of installing it on the very bed of the inkjet machine, the piston diameters and the oil tank are mounted horizontally on the rotary boom and are balanced by the weight of the pump with the electric motor mounted on the console .

The cherge view shows a general view of a hydraulic crane with a partial cut.

The hydraulic crane consists of a rack / mounted on a bed

a paint machine (not shown) and a swing arm 2 with a cantilever 3. On a swing boom 2, the piston cylinder cylinders 4 and 5 and the reservoir 6 with oil are used to drive the pistons 7 and 8 of the cylinders. On the console 3 is installed an electric motor 9, its weight largely balancing the load on the boom from the weight of cylinders and tanks, with oil. On the motor shaft mounted gearbox 10 and pump //.

When you turn on the pump // oil from the tank 6 under pressure enters the lower cylinder 4, controlling the lifting of the tank 12 with paint. The piston 7 is pushed back under the oil pressure and using the system of blocks 13 and the cable 14 lifts the paint tank 12 to the required height. The length of the piston 7 is designed in such a way that at the end of the stroke, the piston closes the bypass hole in the oil line, whereby the oil begins to flow; 5 isepxrunl: cylinder 5. Norm 8 of this cylinder moves back and with the help of a similar system of blocks and cable / 5 turns tank 12 and knocks him into the bunker with the paint mill machine.

To lower the tank, first open the valve 16 of the pipeline and stop the pump by pressing the corresponding button on the button control. The oil from the dil 5 {core 5 is poured back into the tank, and the tank 12 has a vertical position. By closing valve 16 and opening the second valve (7), oil is allowed to enter the tank from cylinder 4, and tank 12 will begin to gently lower. At the end of the descent, the crane / 7 is closed, and the crane

ready for a new climb.

Prevention Invention

Hydraulic swivel crane for loading paste with two-piston-cylinder spray-molding machines, one for lifting and the other for tilting the container with paste, made in the form of a stand and rotating strata with a cantilever, so that the purpose of giving the crane a compact form and the possibility of installing it on the very bed of the ink-hardening machine, the piston cylinders and the oil tank are mounted horizontally on the swing arm and balanced by the weight of the pump with the electric motor mounted on the console.
