DD145255B1 - SAFETY DEVICE FOR PROTECTING THE RIDING AREA OF LIFTING EQUIPMENT FOR LIFTING AND DIVIDING THE ROLLING GEAR - Google Patents

Description

Safety device for securing the driving range on lifting devices for lifting vessels and dumping them.

Field of application of the invention

The invention of a safety device for securing the driving range on lifting devices for lifting and dumping vessels, in particular sausage meat grinders on machines of the food industry

Lifting devices of this type are mainly used in meat processing plants to lift the filled with meat or sausage meat sausage meat from the floor height to the reservoir of the processing machine and to empty in this.

Characteristic of the known technical solutions

There are lifting devices for lifting and dumping of vessels, which are designed as a settable column loaders (DE-GM 7540 068) or as integrated in individual processing machines feeders (DE-OS 2259 599) known. In recent years, a more effective protection of the range of movement of the lifting device of the lifting device has been demanded particularly by the meat processing industry. In particular, the protection of operators when unintentionally entering the hazardous area is increased.

Attention to be given · These requirements were insufficiently solved in the known lifting devices.

Attempts have been made to provide some shielding by reconstructing the range of movement of the load handling device through railings, grates or similar embodiments.

However, these safety devices have the disadvantage that the ümbauungen the range of motion of the load-handling device, the operation of the lifting device is difficult, especially in the inputs and Exquisitions of the sausage car · Furthermore, they adversely affect the Einsatavariabilität the lifting device from #

It is known from DE-GM 7540 068 a lift for motor vehicles, which is equipped with a safety device and then acts when under the load-carrying an object.

This device has the disadvantage that an effectiveness of the safety device takes place only when the load-carrying means is blocked by the object ·

Object of the invention

The aim of the invention is to develop a safety device on lifting devices, which already acts before the load-carrying means and the sausage meat presses on the object located in the range of movement of the load-receiving means.

Erfindagemää the object is achieved in that at the pivot point of the load receiving means 8, preferably below the same, as a protective body, a molded part, with an end face and a bottom plate, is arranged.

The end face is inclined to the bottom plate by an angle / 5 , preferably 120 °. The bottom plate covers the travel range of the load-receiving means, which is arranged movably by an adjustable angle of inclination <K .

embodiment

The invention will be explained in more detail with reference to an embodiment.

In the accompanying drawing show:

Fig 1 side view of the lifting device

Fig. 2 Front view of the lifting device

Fig 3 top view of the lifting device

Fig 4 attachment of the molded part on the load-carrying means

5 shows the representation of the molded part

From Fig 1, a lifting device 1 can be seen, in which below the load receiving means 2, a molded part 3 is mounted. The molded part 3 is movably mounted on the fulcrum 4, which is arranged below the load-receiving fulcrum 5. The pivot point 4 of the molded part 3 can be adjusted vertically by means of a slot guide 6. By a located on the molding part 3 stop 7 of the inclination angle

Of the molded part 3 with respect to the load-receiving means 2 set * on the molded part 3, a switching pin 8 is attached. The associated switching element 9 is arranged on the load receiving means 2 and connected via a prefabricated cable 10 to the control box 11. The end face 12 of the molded part 3 is arranged at an angle of 120 ° to the bottom plate 13.

The function of the safety device is the following:

If, when lowering the load-carrying means 2 with the sausage meat car 14, a person or object arrives in the endangered range of movement 15 of the load-carrying means 2, and if there is contact between the person or the object and the molded part 3t, then the shaped part 3 is out of its inclined position

Position is pressed by the Yfinkel Λ in the horizontal · This is confirmed via the switching pin 3, the switching element 9, which brings the drive motor 16 to an immediate halt and further lowering of the car 14 is avoided. A further lowering is possible only after it has been raised. This is necessary for safety reasons in order to avoid possible incorrect reactions of the operating personnel or to ensure safe removal of the person or the object from the movement area 15 of the load receiving means 2.

By this safety device is achieved that it brings the lifting device already to a halt before the entire load (wagon and load handling equipment) can act on the person or the object. This prevents personal injury and damage to objects and the lifting device.

Claims (1)

invention claim Safety device for securing the driving range of lifting devices for lifting vessels and dumping the same about a pivot point in which when touching an object, a lower part of the protective body against the load-carrying means vertically moves and interrupts the lowering process via limit switch, characterized that at the pivot point (5) of the load-receiving means (2), preferably below the same, as a protective body formtail (3) having an end face (12) and a bottom plate (13), wherein the end face (12) to the bottom plate (13) at an angle / 3 , preferably 120 °, inclined and the bottom plate (13) covers the Fahbereich of the load receiving means (2), is arranged to be movable at an adjustable pitch angle OC $ .
