Next, the protection unit 80 , the adsorption unit 90 , and the elevating cylinder 100 applied to the work die 1 according to an embodiment of the present invention will be described with reference to FIGS. 9 and 10 .

9 is a view illustrating a protection unit, an adsorption unit, a sensor unit, and a lifting cylinder applied to the working die according to an embodiment of the present invention, and FIG. 10 is a control unit applied to the working die according to an embodiment of the present invention. It is a block diagram showing the connection relationship between the sensor unit, the unloading cylinder, the adsorption unit, and the elevating cylinder.

The protection unit 80 is applied to prevent injury even if the worker who is working on the supports (20a, 20b) or the ladder (2) falls.

To this end, the protection unit 80 is disposed on one side and the other side of the supports 20a and 20b, respectively, and elastically by a spring 83 in the inner space of the base 81 and the base 81 formed in a rectangular frame shape. Cushion plate 82 supported and provided with a plurality of through-holes 82a, is disposed to be spaced apart from each other on the ground, and a piston is coupled to the bottom surface of the base 81 to raise or lower the base 81. Cylinder 84 for lowering. , a sensor unit 85 installed on the cushion plate 82 , and a control unit 86 for controlling the operation of the unloading cylinder 84 according to a detection signal of the sensor unit 85 .

The base 81 and the cushion plate 82 may have the same structure as a conventional trampoline.

A plurality of through-holes 82a are formed at regular intervals in the cushion plate 82 for interaction with the adsorption unit 90 to be described later.

A coupling plate (not shown) that is bolted to the bottom surface of the base 81 may be formed on the upper surface of the piston of the unloading cylinder 84 .

The piston of the unloading cylinder 84 is normally raised to support the base 81 at a certain height.

The sensor unit 85 may be applied as a weight sensor. In this case, the sensor unit 85 may be applied as an impact sensor instead of a weight sensor.

A plurality of sensor units 85 may be applied so that the cushion plates 82 are spaced apart from each other at regular intervals.

When a worker located on the supports 20a and 20b or the umbilical ladder 2 falls to the cushion unit, the sensor unit 85 detects it and transmits it to the control unit 86 .

When the control unit 86 receives a detection signal from the sensor unit 85, by lowering the piston of the unloading cylinder 84 to lower the base 81, the operator located on the cushion plate 82 can easily descend to the ground. make it possible

Then, the control unit 86 raises the base 81 by raising the piston of the dismounting cylinder 84 when the detection signal is not generated from the sensor unit 85 .

On the other hand, the adsorption unit 90 is disposed under the cushion plate 82 , and the adsorption unit 90 is raised or lowered with respect to the cushion plate 82 by the elevating cylinder 100 .

The adsorption unit 90 has a plurality of vacuum passages formed therein to adsorb the bottom surface of the cushion plate 82 by vacuum pressure.

The piston of the lifting cylinder 100 is normally raised to bring the adsorption unit 90 into contact with the bottom surface of the cushion plate 82 .

When the sensor unit 85 senses a load on the cushion plate 82 , the control unit 86 generates vacuum suction in the suction unit 90 to adsorb the cushion plate 82 .

At this time, the vacuum suction force of the adsorption unit 90 may be applied to the upper side of the cushion plate 82 through the through hole 82a.

Therefore, when the operator located on the supports 20a, 20b or the ladder (2) accidentally falls to the cushion unit, the adsorption unit 90 operated by the control unit 86 controls the worker located on the cushion plate 82. It can be fixed with vacuum suction power to prevent it from being thrown out to the ground.

For example, when the expansion and compression force of the spring 83 supporting the cushion plate 82 is not large, the control unit 86 controls the adsorption unit 90 only when the sensor unit 85 detects less than 1 g to 10 kg. ) can also be programmed to work.

That is, when a worker who was working on the supports 20a, 20b or the ladder 2 accidentally drops various work tools, such as bolts, nuts, and drills, which are relatively light in weight, onto the cushion plate 82, the sensor unit (85) senses the load of the work tool and transmits it to the control unit 86, and the control unit 86 operates the suction unit 90 to generate a vacuum suction force so that the work tool that has fallen to the cushion plate 82 is moved to the ground. It can prevent it from being thrown out.

In this case, since the work tools are collected on the cushion plate 82 , loss of the work tools can be prevented, and the work tools can be easily collected.
