Description

Technical Field

[0001] The utility model belongs to the technical field of ship loading and unloading operations, and in particular relates to an emergency stop servo control device for ship loading and unloading operations. Background Art

[0002] When an oil tanker is mooring and loading and unloading, in order to ensure safe production management and operation, it is necessary to deploy intelligent sensors through the production automatic control management system to monitor the pressure and temperature data of the loading and unloading media in real time. When the terminal management personnel encounter that the pressure and temperature of the loading and unloading media exceed the safety threshold, the terminal management personnel must notify the onboard personnel through wireless high frequency and inform them to go to the emergency switch area to press the emergency stop button to interrupt the transmission of the media.

[0003] Therefore, in the actual operation of the tanker, there are the following defects: 1. Since it requires terminal personnel to go to the designated location to manually press the emergency stop button, there is a certain time difference in the actual operation process, which makes it impossible for the ship to take emergency response measures immediately, and there are major safety hazards in production; 2. Since the terminal management personnel cannot detect abnormal pressure and temperature of the loading and unloading media in the first time 24 hours a day, and the terminal management personnel cannot guarantee that they can get in touch with the personnel on board at all times, there will also be problems of lack of timely communication and low communication efficiency, which will result in the personnel on board being unable to deal with it in the first time. Utility Model Content

[0005] In order to solve the above technical problems, the technical solution provided by the utility model is: a ship loading and unloading operation emergency stop servo control device, which includes a power cabinet and an intelligent sensor for monitoring the status of loading and unloading media, and also includes a support frame, both ends of the support frame are provided with vertical guide columns, and the upper clamping plate and the lower clamping plate are vertically slidably installed on the vertical guide columns; a fixed plate is installed in the middle of the support frame, and a linear drive mechanism is provided on one side of the fixed plate, the linear drive mechanism is electrically connected to the power cabinet and the intelligent sensor, and a push block is installed on the power output end of the linear drive mechanism; a bidirectional screw is rotatably installed in the middle of the fixed plate, the rotation direction of the upper end of the bidirectional screw is opposite to that of the lower end of the bidirectional screw, and the upper end of the bidirectional screw passes through the fixed plate and is threadedly connected to the upper clamping plate, the upper clamping plate is provided with at least one row of upper fixed sockets along the height direction, and the upper fixed pin is inserted in the upper fixed socket; the lower end of the bidirectional screw passes through the fixed plate and is threadedly connected to the lower clamping plate, the lower clamping plate is provided with at least one row of lower fixed sockets along the height direction, and the lower fixed pin is inserted in the lower fixed socket. Based on this, the main part of the utility model can be directly connected to the emergency button installation box through the lower fixed pin and the upper fixed pin, and when the pressure and temperature of the loading and unloading medium are abnormal, the signal can be directly transmitted to the linear drive mechanism through the intelligent sensor (this is a conventional sensor control technology on the market, so it will not be described in detail here), and the corresponding button action can be performed to achieve one-button emergency stop operation, shorten the emergency response time, minimize the losses caused by accidents, realize the refinement and intelligence of port operations, and improve the inherent safety management of port operations and production.

[0006] Furthermore, the linear drive mechanism is a servo drive mechanism to ensure that it has sufficient accuracy.

[0007] Furthermore, the linear drive mechanism includes an electric push rod, the fixed end of the electric push rod is fixedly mounted on the fixed plate, the telescopic end of the electric push rod is fixedly mounted on the push block, and the telescopic end of the electric push rod drives the push block forward or backward to realize the corresponding button action.

[0008] Furthermore, at least two upper fixing jacks are provided in each row along the horizontal direction on the upper card plate, and the specific number thereof can be selected according to the width of the emergency button installation box.

[0009] Furthermore, the upper card plate is provided with at least two rows of upper fixing holes along the height direction, and the specific number thereof can be flexibly selected.

[0010] Furthermore, at least two lower fixing holes are provided in each row along the horizontal direction on the lower card plate, and the specific number thereof can be selected according to the width of the emergency button installation box.

[0019] The power cabinet 14 is used to provide power to the emergency stop servo control device of the entire ship loading and unloading operation, and the intelligent sensor is used to monitor the temperature and pressure of the loading and unloading medium. The intelligent sensor directly uses a sensor structure commonly used in the existing technology and available for purchase.

[0020] Both ends of the support frame 10 are fixedly provided with vertical guide columns 8, and the upper card plate 6 and the lower card plate 11 are vertically slidably installed on the vertical guide columns 8; the middle part of the support frame 10 is fixedly provided with a fixed plate 9, and the fixed plate 9 is provided with a linear drive mechanism 15 on the side facing the inner cavity of the emergency button installation box 1. The linear drive mechanism 15 is electrically connected to the power cabinet 14 and the intelligent sensor, and the power output end of the linear drive mechanism 15 is provided with a push block 2 for pressing the emergency stop emergency button in the emergency button installation box 1. Specifically, the linear drive mechanism 15 is an electric push rod, the fixed end of the electric push rod is fixedly installed on the fixed plate 9, and the telescopic end of the electric push rod is fixedly installed with the push block 2, and the electric push rod is preferably a servo electric push rod.

[0021] A bidirectional screw rod 7 is rotatably mounted on the middle portion of the fixing plate 9 via a nut seat. The rotation direction of the upper end of the bidirectional screw rod 7 is opposite to that of the lower end of the bidirectional screw rod 7. The upper end of the bidirectional screw rod 7 passes through the fixing plate 9 and is then threadedly connected to the upper clamping plate 6. The upper clamping plate 6 is provided with at least one row of upper fixing holes 3 in the height direction, and each row of upper fixing holes 3 is provided with at least two upper fixing holes 3 in the horizontal direction, and one of the rows of upper fixing holes 3 is plugged with an upper fixing pin 5.
