Description

[0020] The invention is explained below on the basis of a preferred exemplary embodiment, which is depicted schematically in the drawings. In the drawings there are shown:

[0021] FIG. 1 a side view of a civil engineering device according to the invention and

[0022] FIG. 2 a picture of a signalling on the civil engineering device of FIG. 1.

[0023] According to FIG. 1, a civil engineering device 1 according to the invention is designed as a drill rig. The civil engineering device 1 has a carrier apparatus 9 with an undercarriage 10, on which an upper carriage 11 with a control station 22 and a drive unit 28 are supported rotatably.

[0024] A vertical mast 14 is supported pivotably on the upper carriage 11 via a mast linkage 12. Arranged on a front side of the mast 14 is a mast guide 16, along which a mast carriage 15 with a drill drive 18 is supported displaceably. The drill drive 18 drives a drilling tool in a rotary manner, which tool is mounted in a generally known manner on a kelly bar 19, which is in turn supported vertically adjustably via a main cable 5 over a mast head 17.

[0025] According to the invention, a transversely directed mast head 17 is mounted on the upper end of the mast 14, on the underside of which two cameras 30 of a surveillance system according to the invention are arranged. The cameras 30 are directed downwards to produce an image 60 of the civil engineering device 1 from above, which is shown by example in FIG. 2.

[0026] Here, the images from the cameras 30, which are arranged on the transversely directed mast head 17 on a front and rear side with respect to the mast 14, are transmitted to a control unit 20 in the control station 22 of the carrier apparatus 9. Here, the control unit 20 can have a monitor on which the image schematically depicted in FIG. 2 is composed from the images of the cameras 30 by means of image processing software and is displayed.

[0027] In the image 60 thus produced, the civil engineering device 1 and surroundings are shown with a predefined, circular security area 2 in the exemplary embodiment depicted. The security area can be projected by the software of the control unit into the image to create a better overview for an operator. If a person or object approaches relative to the civil engineering device 1 and enters the security area 62, a warning signal can be emitted acoustically, optically or in another way via the control unit 20.

[0028] The security area 62 is preferably divided into an outer annular warning area 64 and an inner circular warning area 66. The individual warning areas 64, 66 can themselves be divided into further sectors, thus into a front sector 68, a rear sector 69 and two lateral sectors 70 in the exemplary embodiment depicted. In the event of an ingress into these different warning areas 64, 66 or sectors, different measures can be taken by the control unit. Thus upon an ingress only into the annular outer warning area 64, a warning signal can be emitted. In the event of a further advance relative to the civil engineering device 1 into the inner warning area 66, which can represent a direct hazard zone in operation of the civil engineering device, an operating stop can be initiated by the control unit, for example.

[0029] An increased occupational safety and improved surveillance of the civil engineering device 1 can thus be achieved by the system according to the invention. In particular, the cameras 30 can be operating even when the civil engineering device 1 is at a standstill, in order to detect an unauthorised access to the civil engineering device 1, for instance, and to communicate this to a control unit 20, which can also be arranged remotely from the civil engineering device 1. Suitable countermeasures can then be initiated from a suitably remote control centre with the control unit 20, such as the emission of a warning signal, switching the lighting on and/or delivering information to a security or guard staff.
