[0021] Exemplary embodiments of the invention are described in more detail below with reference to the figures, wherein show schematically and by example: Fig. 1 shows a pipe storage device for conveying lines.

[0022] Fig. 1 schematically shows a pipe storage device 100 for a conveying line 102 for bulk material. The conveying line 102 can be part of a pneumatic slow conveying system used for transporting bulk materials. Pipe support device 100 is for transferring forces or loads from the conveying system to a support structure (in Fig. 1 (not shown) is formed. This allows, for example, at deflection points and / or geological or Weather-related impact forces are dampened and transferred into the supporting structure.

[0023] The pipe storage device 100 has a pipe storage (101) with a pipe holder 104 for holding the conveying line 102 and a damping device 106 for damping forces. The damping device 106 is connected to the The support structure of the conveyor system can be connected. In the present embodiment, the damping device 106 trained, sudden forces occurring in the conveying line 102, e.g. impact forces, kinetic forces or the like, when to dampen the transmission to the support structure. For this purpose, the damping device 106 is located between the pipe holder. 104 and the supporting structure can be effectively arranged. The forces can be, for example, caused by the movement of the conveying line. 102 or one thereby on the Pipe holder 104 may be subjected to an acting load, such as a tensile, compressive or shear load.

[0024] To dampen the movements or forces, the damping device 106 has at least one elastic element. 108. In the present embodiment, the damping device 106 has six elastic elements 108, of which in Fig. 1 shows three schematic representations. The elastic elements 108 are designed here as rubber buffers. Furthermore, it shows The damping device 106 has a base plate 110, which serves for mounting with the support structure. The rubber buffers 108 are arranged on the base plate 110 and screwed to it.

[0025] The pipe holder 104 comprises a retaining plate 112 and two substantially semicircular plates attached thereto Half-shells 114 for receiving the conveying line 102. The conveying line 102 can be attached to the The outer circumference can be fixed with the pipe holder 104. Additionally, lugs (not shown in Fig. 1) can be used for the Welded joints are used.

[0026] As shown in Fig. 1, the rubber buffers 108 are located between the base plate 110 of the damping device 106 and the retaining plate 112 of the pipe holder 104 are effectively arranged. The retaining plate 112 and the base plate 110 are thus The rubber buffers 108 are connected to each other in such a way that movement of the pipe holder 104 relative to the Damping device 106, in particular relative to its base plate 110, is possible.

For this purpose, it indicates The damping device 106 has a sensor 118 which detects a relative movement between the retaining plate 112 and the Base plate 110 detects and thus, for example, detects a movement of the conveying line 102 onto the pipe holder. 110 can detect the impact exerted. In the present embodiment, the sensor 118 is an inductive sensor. formed and mounted on the base plate 110. On the side opposite the sensor 118, on the mounting plate A switching flag 120 is attached to 112. When the pipe bearing 101 is in its resting position, the switching flag is in the 120 concentrically above the active sensor area of ​​sensor 118.

[0028] If an impact occurs and thus a movement of the retaining plate 112, the switching flag 120 shifts relative to the Sensor 118. The detection device 116 can thus detect a displacement, e.g. positional displacement or change in position, of the The pipe holder 104 is detected relative to the base plate 110. In the present embodiment, no detection takes place by The sensor 118 is activated when an impact occurs whose force does not exceed a threshold value. In this case, the Switch flag 120 in a movement range where the active sensor area of ​​sensor 118 is still sufficient is damped. The threshold value can, for example, be a maximum permissible load on the pipe support 101. In the case of a An impact that exceeds the threshold value results in insufficient or no damping of sensor 118. no longer present. Sensor 118 detects this condition and outputs a signal. Preferably, the signal is sent to a Evaluation unit (not shown in Fig. 1) passed on. The evaluation unit can be located at pipe storage 101. It may be intended to be used as part of an external, e.g., central, control system. The signal is processed in the evaluation unit. evaluated. To rule out a false detection, e.g. due to an excessively strong shock, the signal can be analyzed in the The evaluation unit can also process data further.

[0029] Various parameters can be stored in the evaluation unit. Based on these parameters The signals transmitted by sensor 118 can be further processed and / or evaluated. For example, The evaluation unit must specify when a notification is issued. In one variant, the Parameters might include, for example, a permissible number of signals within a certain period. The number of The signal can serve as an indicator of the stress on the rubber buffers 108. If the number of signals from sensor 118 exceeds the limit, the system can be reactivated. If the number of transmitted signals exceeds the permissible limit stored in the evaluation unit, a message can be issued. The message output can be three-tiered, for example with the messages Caution, Warning and Danger. Each of these alert levels can contain a predetermined number of signals and thus a strain on the system. Rubber buffer 108 should be assigned.

[0030] Alternatively or additionally to transmitting the signals from sensor 118 to the evaluation unit, a pre- Location display is provided (not shown in Fig. 1), which, for example, when the threshold is exceeded or when... Reaching a certain number of sensor detections triggers the process. An acoustic sensor can be installed directly at pipe bearing 101. A signal or a visual signal will be issued.
