[0015] The specific implementation of the present utility model is further described below in conjunction with the accompanying drawings.

[0016] like Figure 1-4 As shown, the interlocking alarm device for preventing the pipe conveyor from running off track of the utility model is characterized in that it includes a pipe conveyor bracket 2, a clamping roller bracket 1 welded on the pipe conveyor bracket 2, a clamping roller 4 arranged on the clamping roller bracket 1, circular limit retaining rings 3 respectively welded on both sides of the clamping roller 4, an iron detection block 5 arranged at either end of the two ends of the clamping roller 4, and an inductive proximity switch 6 arranged within the detection range and with the center aligned with the iron detection block 5.

[0017] The circular limit ring 3 is welded on both sides of the clamping roller 4 according to the limit distance measured by the belt conveyor tape 7.

[0018] The iron detection block 5 has a size of 20 mm×20 mm×20 mm.

[0019] Example:

[0020] A Φ108mm thick-walled clamping roller with the same width as the belt is made to achieve the clamping effect when the belt deviates, and is used to install an alarm iron detection block 5 at its end. When the pipe conveyor belt 7 deviates, the clamping roller 4 contacts the pipe conveyor belt 7, clamps the pipe conveyor belt 7 to continue to deviate, and rotates with the running pipe conveyor belt 7, thereby moving the iron detection block 5 installed at its end for position detection when the pipe conveyor belt deviates.

[0021] Two circular limit retaining rings 3 are made of 20mm thick steel plates, the inner circle of which is slightly larger than the outer diameter of the Φ108mm thick-walled clamping roller 4, and the outer circle is 50mm higher than the outer diameter of the clamping roller in principle so that the thick-walled clamping roller 4 can be smoothly inserted. The circular limit retaining rings 3 are welded on both sides of the clamping roller 4 to prevent the belt 7 of the belt conveyor from continuing to curl and run under the clamping roller 4 when the belt conveyor deviates, thereby realizing the function of limiting the curling and running of the belt conveyor.

[0022] The distance of the circular limit ring is 3, which is based on the width of the first group of rollers (open rollers) of the belt conveyor head in the transition section. The limit distance is 40mm inward at the two points of the limit distance. The circular limit rings are welded on both sides of the clamping roller according to the determined limit distance.

[0023] A 20mm×20mm×20mm iron detection block 5 is welded at either end of the clamping roller 4. When the clamping roller 4 is driven by the belt conveyor to deviate from its original position, the clamping roller 4 will also roll, and the inductive proximity switch 6 will detect the iron detection block 5, thereby disconnecting the control circuit, causing the belt conveyor to stop and alarm. The on-duty personnel will immediately check and troubleshoot and resume the transfer to avoid the belt overturning accident.

[0024] Working process: When the pipe conveyor is in normal operation, the clamping roller 4 is in a stationary state. As long as the pipe conveyor belt 7 deviates, the clamping roller 4 and the circular limit ring 3 installed above the pipe conveyor belt 7 will clamp the deviated belt to limit its further deviation. At the same time, the running belt will be brought to the clamping roller to rotate together. At this time, the inductive proximity switch 6 will detect that the clamping roller 4 is rotating and send out a detection signal, proving that the pipe conveyor is in the initial state of deviation. The electronic control system will immediately shut down and send out an audible and visual alarm, conduct timely inspections, eliminate hidden dangers, prevent equipment accidents, and ensure smooth production.

[0025] like Figure 4 As shown in the figure, when the belt conveyor belt 7 deviates, the normally open contact of the proximity switch SQ (8-9) is closed, connecting the intermediate relay KA coil, and the normally open contact of the intermediate relay KA (8-9) is closed to achieve self-locking, keeping the intermediate relay KA coil continuously energized. The normally open contact of the intermediate relay KA (8-12) is closed to connect the BJQ sound and light alarm circuit, and the BJQ sound and light alarm sounds. At the same time, the normally closed contact of the intermediate relay KA (13-14) is disconnected, sending the interlocking signal to the tripping circuit of the original belt conveyor electronic control system, and the belt conveyor is interlocked and stops and sounds an alarm.

[0026] The utility model discloses an interlocking alarm device for preventing the belt conveyor from deviation, realizes the prediction of the belt conveyor belt deviation, clamps the deviation to prevent the belt conveyor belt from turning over accident, ensures the stable operation of the equipment, avoids the influence on the production, ensures the safety, reduces the cost consumption, improves the equipment efficiency, and reduces the labor intensity of the maintenance personnel.
