Description

Technical Field

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

[0002] The old-style oil supply system is generally integrated inside the factory building, with a long construction period, backward technology, low degree of automation, and cannot be relocated.

[0003] The work that needs to be completed during normal oil unloading cannot be done in one go, such as opening the oil pilot valve, listening to the oil loading situation, closing the oil pilot valve, observing the oil level in the tanker, etc. These operations need to be performed repeatedly, and some operations need to be completed in a timely manner. For example, when the oil is unloaded, if the valve is not closed in time, air reflux will occur, causing air to be sucked into the oil manifold connected to the rear end of the crane pipe, and the oil will flow back into the tanker, causing an oil return accident. The operation needs to be carried out in an orderly manner to ensure the safety of the operation process. Each operator is required to be experienced and skilled in operation, and each person cannot be responsible for too many crane positions.

[0004] According to the status analysis and the actual situation of each oil unloading station, the operation of the oil unloading station is sometimes not full and sometimes overloaded. In order to meet the needs of multiple cranes unloading at the same time and ensure the safety of the operation, each oil unloading station can only be staffed according to the full-load state of oil unloading, which has caused low staff efficiency and rising costs. At the same time, because the work of the trestle operators is complicated and labor-intensive, they also need to concentrate highly, which inevitably causes physical fatigue. In addition, there are risks of high-altitude operations and inhalation of toxic gases, which often cause safety accidents. Summary of the invention

[0005] The first object of the present invention is to provide an interlocking control system for railway trestle oil unloading equipment, which is provided with an oil unloading execution unit, an information monitoring unit and a signal indication unit, wherein the information monitoring unit is installed near the oil unloading execution unit, and the information monitoring unit is connected to the signal indication unit. When in use, when the information monitoring unit detects that the oil unloading execution unit has not been reset, the signal indication unit gives an indication, which effectively avoids the oil unloading equipment and the oil tank truck not being completely separated due to inadequate inspection by personnel, resulting in the oil tank truck dragging the trestle, causing equipment damage, oil leakage or personnel injury and other abnormal situations, thereby ensuring that the oil unloading operation is carried out safely and orderly;

[0006] The second purpose of the present invention is to provide an interlocking control method for railway trestle oil unloading equipment. The method technically controls the risk of oil tankers dragging the trestle, facilitates operators to review and check the equipment reset status, greatly reduces the labor intensity of front-line operators, and has a positive impact on further standardizing operations and improving labor efficiency.

[0010] The signal indication unit comprises a central controller, and the central controller is provided with an indicator light group;

[0011] The information monitoring unit is installed near the oil unloading execution unit, and the information monitoring unit is connected to the signal indication unit;
