Description

Technical Field

[0001] The utility model relates to a sensor-based intelligent safety clamping detection device for anode carbon blocks, in particular to a device for intelligently detecting abnormal clamping states of anode carbon blocks of a fully automatic anode gravity stacking crane. Background Art

[0002] In the production process of anode carbon blocks, stacking cranes are important carbon block transfer equipment, and their operating conditions are directly related to production safety and efficiency. Nowadays, driven by the trend of intelligence, the intelligent unmanned operation of stacking cranes has become an urgent need for many carbon enterprises. However, due to long-term use, wear of clamping nails, production process and other reasons, stacking cranes may have block carrying, block leakage, and block sticking when clamping carbon blocks.

[0003] When the stacking crane puts down a row of carbon blocks, some of the carbon blocks are carried up during the lifting because some clamps are not fully opened. When the stacking crane clamps a row of carbon blocks, some of the carbon blocks are not clamped during the lifting because some clamps are not fully closed. When the stacking crane clamps a row of carbon blocks, some of the carbon blocks in the next layer are stuck and carried up during the lifting due to the production process and long-term stacking. These situations will not only cause damage to the equipment and carbon blocks, but may also cause serious safety accidents. Therefore, timely and accurate detection of the carbon block clamping status is of great significance to ensure the safe and unmanned operation of the intelligent stacking crane.

[0004] The traditional anode carbon block clamping detection method can only detect whether there is a block and uses a mechanical limit method. This method is not only difficult to modify and install, but also easily affected by many factors, resulting in false detection and missed detection. Summary of the invention

[0005] The purpose of the utility model is to solve the defects in the prior art and provide a device which can detect the abnormal state of the intelligent anode gravity stacking crane when clamping the carbon blocks in real time and accurately.

[0006] In order to achieve the above-mentioned purpose, the utility model provides an intelligent and safe clamping detection device for anode carbon blocks, which is used to detect the safe clamping state of a clamp group; the intelligent and safe clamping detection device for anode carbon blocks includes a clamping sensor for detecting the opening of the clamp, an intelligent sensing device for detecting the distribution of carbon blocks under the clamp, and a PLC; there are multiple clamping sensors, which are respectively installed on the crossbeam brackets of the corresponding clamps; the intelligent sensing device is installed on one side of the clamp group through a liftable bracket; when the liftable bracket is in a raised state, the plane where the bottom of the intelligent sensing device is located is above the clamp; when the liftable bracket is in a lowered state, the intelligent sensing device is facing the carbon blocks in a sticky state under the clamp; the clamping sensor and the intelligent sensing device are both connected to the PLC.

[0007] The utility model obtains the opening degree of the clamp through a clamping sensor, thereby detecting whether there is a strip block or a missing block; obtains the distribution of the next layer of carbon blocks through an intelligent sensing device, thereby detecting whether carbon block adhesion occurs; and processes and analyzes the data of each sensor device through a PLC, and sends out an alarm stop signal.

[0008] Furthermore, the clamping sensor adopts a stretching encoder to output an analog signal, and the mechanical displacement is detected by the stretching encoder to calculate the clamp opening.

[0009] The liftable support may be made of steel, such as an automatic telescopic rod.

[0010] Furthermore, the intelligent sensing device uses a three-dimensional scanner or a video camera.

[0011] Furthermore, the anode carbon block intelligent safety clamping detection device of the present invention also includes a tilt sensor; there are multiple tilt sensors, which are respectively installed on the corresponding clamps; each tilt sensor is connected to the PLC. The real-time tilt angle of the clamp is obtained through the tilt sensor, so as to detect whether the clamp is over-tilted.

[0012] Furthermore, the tilt sensor adopts a 2-axis inclinometer and outputs an analog signal.

[0013] The utility model has the following beneficial effects:

[0014] The utility model performs intelligent judgment and analysis through sensor detection and three-dimensional scanning of intelligent sensing equipment, and the PLC sends out an alarm signal, which can detect abnormal working conditions in real time, and alarm and shut down in time to ensure the safety of the intelligent clamping process.

[0017] In order to explain the problems to be solved and the technical advantages of the present invention more conveniently and in detail, the drawings and the specific examples therein will be described in detail below.

[0018] This embodiment provides a sensor-based anode carbon block intelligent safety clamping detection device for detecting abnormal working conditions of a clamp group. Take a single clamp (a gravity clamp is used in this embodiment) as an example. Figure 1As shown, the distance from the crossbeam support 1 to the clamp frame 5 is detected by the clamping sensor 2 installed on the clamp crossbeam support 1. When clamping the carbon block, this distance will change linearly with the clamp opening. The corresponding clamp opening is obtained by linear calculation, so as to detect whether the block is carried or missed. The transition pull plate 4 is installed as a whole with the crossbeam support 1 and the clamp frame 5 through the connecting shaft. The tilt angle sensor 3 installed on the clamp frame 5 is used to judge the tilt angle of the clamp frame 5, the clamp frame 6, and the clamp 7, so as to detect whether the clamp and the anode carbon block 8 are excessively tilted. The clamp frame 5 and the clamp frame 6 are connected as a whole through a mechanical structure, and the clamp 7 and the clamp frame 6 are installed as a whole through a connecting shaft.

[0019] like Figure 2 As shown, the distribution of the next layer of carbon blocks is detected by an intelligent sensing device 10 installed on one side of the clamp group, so as to detect whether carbon blocks are sticking. The intelligent sensing device is installed at one end of the liftable bracket 9. The liftable bracket can change the lifting height according to the control command. When the clamp is raised, the bracket automatically descends, and the intelligent sensing device performs detection. After the detection is completed, the bracket automatically rises back to the initial position.

[0020] When the sensor-based anode carbon block intelligent safety clamping detection device of the utility model is working, relevant data is collected through various sensors and intelligent sensing devices, and transmitted to the PLC for processing and analysis. The PLC calculates through the alarm judgment logic, compares the result with the alarm threshold, and alarms and stops when the threshold is exceeded, and continues to run when it is below the threshold.

[0021] The utility model of intelligent and safe anode carbon block clamping detection method has the following advantages:

[0022] 1.Automated detection: The carbon block clamping status is automatically detected by the sensor without manual intervention, which improves the detection efficiency.

[0023] 2. High accuracy: The sensors involved are highly adaptable to the scene and have been tested for a long time, and can accurately detect abnormal conditions that occur when clamping carbon blocks.

[0024] 3. Real-time: By detecting data in real time and processing it quickly, abnormal conditions when clamping carbon blocks can be discovered in time to avoid safety risks.

[0025] Although the utility model has been disclosed exemplarily, it should be understood that the above are only preferred embodiments and are not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
