[0001] The utility model relates to the technical field of safety control equipment, in particular to an interlocking control system for railway trestle oil unloading equipment. Background Art

[0002] The railway oil unloading station is a key unit to ensure the normal operation of the aviation oil supply chain. At present, the oil unloading method of the oil unloading station is to unload oil through railway trestle oil unloading equipment (such as loading arms, oil pumps, and flushing hoses). During the unloading process, the pedestrian ladder on the trestle, the loading arm, and the flushing hose must be in contact with the tank car. At the end of the oil unloading operation, each equipment needs to be retracted in place, especially the pedestrian ladder and the loading arm; if the equipment is not effectively in place and is in contact with the tank car, the equipment will be damaged or even the trestle will be damaged during the movement of the tank car, resulting in risks such as personal injury or oil leakage.

[0031] Embodiment 1

[0032] As Figure 1-2As shown in the figure, an interlock control system for a railway trestle oil unloading device includes a first sensor 2 installed on one side of the pedestrian ladder for detecting the position of the pedestrian ladder, and the first sensor 2 corresponds to the pedestrian ladder one by one; a second sensor 3 installed on one side of the loading arm for detecting the position of the loading arm, and the second sensor 3 corresponds to the loading arm one by one; both the first sensor 2 and the second sensor 3 adopt magnetic proximity switches, which can detect the relative positions between the pedestrian ladder, the loading arm and the corresponding sensors.

[0033] An alarm module 4, which is electrically connected between the alarm module 4 and the first sensor 2 and the second sensor 3; the alarm module 4 includes a first alarm module 401, and the first alarm module 401 is electrically connected to the first sensor 2; the alarm module 4 includes a second alarm module 402, and the second alarm module 402 is electrically connected to the second sensor 3. The alarm module 4 can adopt a status indicator light or a buzzer, and the status indicator light is an LED light that can display green and red, which is convenient for warning the staff.

[0034] An automatic gear lever 8 is arranged in the driving direction of the oil tank truck. The automatic gear lever 8 is electrically connected to a pressing control switch. When the automatic gear lever 8 is powered on, the staff can adjust the switch state of the automatic gear lever 8 by pressing the control switch. A reminder module 6 is arranged on one side of the switch of the automatic gear lever 8. The reminder module 6 can adopt a release signal light, which is convenient for the driver of the oil tank truck to confirm the reset situation of the equipment.

[0035] A safety interlock device 7, which is electrically connected between the alarm module and the automatic gear lever 8; a controller 1, and the controller 1 includes a storage module 101, in which the reset positions of the pedestrian ladder and the loading arm are set. The controller 1 is electrically connected to the first sensor 2, the second sensor 3, the safety interlock device 7, the alarm module 4, and the reminder module 6.

[0036] The controller 1 preferably adopts a PLC controller for controlling the operation and coordination of the entire interlock control system. The controller 1 receives the detection results of the first sensor 2 and the second sensor 3, compares them with the reset positions of the pedestrian ladder and the loading arm stored in the storage module 101, thereby confirming the reset situation, and enables the alarm module 4 and the reminder module 6 to issue warning signals to control the switch state of the automatic gear lever 8, and at the same time activates the safety interlock device 7. The safety interlock device 7 can adopt an existing safety interlock switch, which can cut off the circuit under specific conditions.

[0037] When any one of the first sensor 2 and the second sensor 3 detects that the device reset is incomplete, the corresponding alarm module 4 gives an alarm, that is, the status indicator light shows red, and the release signal light adopted by the reminder module 6 turns red; at the same time, the detection result can be used as the start signal of the safety interlock device 7. After receiving the signal, the safety interlock device 7 cuts off the circuit of the automatic gear rod 8, so that the automatic gear rod 8 is powered off. At this time, pressing the control switch cannot open the automatic gear rod 8, effectively avoiding safety accidents caused by the oil tank truck driving away before the device reset is completed.

[0038] When any one of the first sensor 2 and the second sensor 3 detects that the device reset is complete, all the status indicator lights turn green, and the release signal light turns green; at the same time, the detection result is used as the closing signal of the safety interlock device 7. After receiving the signal, the safety interlock device 7 connects the circuit of the automatic gear rod 8. At this time, the staff can open the automatic gear rod 8 by pressing the control switch, so that the oil tank truck can drive away smoothly.

[0039] The utility model further includes a central control display 5, which is electrically connected to the controller 1 and is used to display the alarm result of the alarm module 4. When the alarm module 4 adopts status indicator lights, each status indicator light is installed on the central control display 5, which is convenient for the staff to find problems in time and confirm the device reset detection situation without inspecting the trestle.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
