Description

Technical Field

[0001] The present invention relates to the technical field of screw ship unloaders, and particularly to a remote operation control system for a screw ship unloader. Background Art

[0002] In the logistics port industry, ship unloading technology has become the core technology of bulk cargo specialized terminals. The screw ship unloader has the advantages of high ship unloading efficiency, light structure, flexible operation, pollution-free closed transportation, strong adaptability to materials and ship types, etc. It is a continuous ship unloading model with excellent performance and a high market occupancy rate, and has strong market vitality.

[0003] A screw ship unloader disclosed in Chinese Patent Publication No. CN206939967U includes a support platform. On both sides of the bottom of the support platform, there are walking mechanisms respectively, and clamping wheel devices are arranged on the walking mechanisms, and a clamping wheel device system is arranged at the bottom of the support platform. An anti-wind system is fixedly arranged on the walking mechanisms. A slewing mechanism is arranged at the upper end of the support platform, a vertical chute assembly is arranged at the upper end of the slewing mechanism, and a cylindrical gantry connected to the vertical chute assembly is arranged at the lower end. A gantry screw assembly is arranged on the support platform to control the slewing mechanism. A sliding contact line support and an electric control system are arranged on the right side of the support platform, and an operation room is arranged on the left side. A horizontal arm assembly is arranged at the top of the slewing mechanism, a horizontal screw assembly connected to the vertical chute assembly is arranged in the horizontal arm which is a component of the horizontal arm assembly, and a lubrication system is arranged at the upper end of the horizontal screw of the horizontal screw assembly part; when discharging materials in the above solution, the feeding head located at the end rotates to contact the materials, and the accumulated materials are scattered. The scattered materials are conveyed upward by the conveying auger in the vertical screw assembly to realize the unloading of the materials in the ship. When discharging materials, usually an operator uses a remote controller to operate to realize the displacement of the feeding head and the conveying of the materials. However, in actual unloading, the ship is large in volume and the distance between the feeding head and the operator is far, resulting in the inability to accurately control the position of the feeding head. When encountering materials that are caked after long-term accumulation, the materials cannot be effectively scattered, resulting in difficulty for the feeding head to effectively contact the materials, causing the auger to rotate idly for a long time and unable to be detected in time, affecting the unloading efficiency.

[0010] As a further scheme of the present invention, a main auger is installed in the middle of the vertical screw pipe. A transfer wheel is rotatably connected to the middle of the transverse pipe. The main auger and the material taking auger are linked through the transfer wheel.

Specific embodiments Embodiment 1

[0020] As Figures 1-4As shown in the figure, a remote operation control system for a screw ship unloader includes a vertical screw assembly and a remote intelligent controller 5. The vertical screw assembly includes a vertical screw pipe 1 and a material taking head 2. The vertical screw assembly is a common component in a screw ship unloader and is used to transfer the materials in the cabin to a designated position. In the prior art, the specific structure and working principle of the present application will not be elaborated here. The vertical screw pipe 1 and the material taking head 2 are arranged in a staggered manner. The top port of the material taking head 2 is rotatably connected to a transverse pipe 3. By rotating the material taking head 2, the materials in the cabin are scattered and conveyed to the transverse pipe 3 through the bottom of the material taking head 2 and then transferred to the vertical screw pipe 1 for unloading the materials. By setting a two-stage structure for the vertical screw pipe 1 and the material taking head 2, the pressure on the auger during the vertical upward movement of the materials is reduced. The other end of the transverse pipe 3 is rotatably connected to the bottom port of the vertical screw pipe 1. A deflection control component 6 is installed on the vertical screw pipe 1, and the output end of the deflection control component 6 is connected to the transverse pipe 3 to drive the transverse pipe 3 to rotate around the axis of the vertical screw pipe 1. When the transverse pipe 3 deflects, it will drive the material taking head 2 at the end to rotate around the axis of the vertical screw pipe 1, thereby adjusting the position of the material taking head 2 and adjusting the position of the feed inlet of the material taking head 2. When targeting positions such as the edge of the cabin, the material taking head 2 is adjusted to be close to the edge of the cabin to reduce the unloading dead angle and improve the unloading efficiency.

[0021] It is worth mentioning that, as shown in Figure 4 , Figure 5 and Figure 8 shown, a material taking detection chamber 11 is installed at the position corresponding to the top port of the transverse pipe 3 and the material taking head 2. A first sealing pressure plate 22 is arranged between the inner cavity top of the material taking head 2 and the inner cavity of the material taking detection chamber 11. A first air pressure sensor 21 is installed in the inner cavity of the material taking detection chamber 11 to detect the air pressure value of the chamber formed by the first sealing pressure plate 22 and the inner cavity of the material taking detection chamber 11. When the material taking head 2 is normally conveying materials, the materials enter the material taking head 2 from bottom to top. At this time, the materials will squeeze the first sealing pressure plate 22 at the top of the material taking head 2 and compress the cavity above the first sealing pressure plate 22, thereby changing the air pressure value of the chamber where the first sealing pressure plate 22 is located. When the material taking auger 17 is idling, as shown in Figure 8 at this time, the extrusion force of the materials on the first sealing pressure plate 22 decreases, and the air pressure value of the chamber where the first sealing pressure plate 22 is located also decreases. Therefore, it can flexibly detect whether the material taking head 2 is idling, which is convenient for remotely controlling the screw ship unloader.

[0022] And, please refer to Figure 6, a remote intelligent controller 5 is provided with a remote data transmission module, a detection and analysis module, an idling processing module and a reminder module. The remote data transmission module is respectively signal-connected to a first air pressure sensor 21 and a deflection control assembly 6 through a wireless transmission mode. The remote data transmission module is signal-connected to the detection and analysis module. The detection and analysis module is respectively signal-connected to the reminder module and the idling processing module. When the screw ship unloader works to unload the materials in the cabin, the materials enter through the bottom of the material taking head 2 and enter the vertical screw pipe 1 through the transverse pipe 3. During this process, the first air pressure sensor 21 wirelessly transmits the detected air pressure value to the detection and analysis module in real time through the remote data transmission module. The detection and analysis module sends the air pressure value of the first air pressure sensor 21 to the idling processing module for processing. The idling processing module compares the air pressure value fed back by the first air pressure sensor 21 with a preset normal air pressure value (the normal air pressure value of the chamber where the first air pressure sensor 21 is located when the material taking head 2 is discharging materials normally is preset in the idling processing module). When the idling processing module determines that the air pressure value fed back by the first air pressure sensor 21 is less than the preset normal air pressure value, it is determined that the material taking head 2 is in an idling state. At this time, the materials are caked or not in contact with the material taking head 2. The idling processing module sends the judgment result to the detection and analysis module. The detection and analysis module sends a reminder signal to the reminder module. The reminder module reminds the operator holding the remote intelligent controller 5 that the material taking head 2 is in an idling state in the form of light and sound, so as to facilitate the operator to timely understand the working state of the material taking head 2. At the same time, the detection and analysis module wirelessly controls the deflection control assembly 6 to work through the remote data transmission module. The work of the deflection control assembly 6 will control the material taking head 2 to deflect, so as to automatically adjust the position of the material taking head 2 until the material taking head 2 normally discharges the materials. At this time, the idling processing module determines that the air pressure value fed back by the first air pressure sensor 21 returns to the normal air pressure value. The detection and analysis module wirelessly controls the deflection control assembly 6 to stop working through the remote data transmission module. Therefore, when the vertical screw assembly unloads the materials, it can automatically judge the working state of the material taking head 2, and when the auger in the material taking head 2 is in an idling state, it can automatically control the material taking head 2 to deflect until it is in full contact with the materials, effectively unload the materials, further make up for the situation that the operator cannot accurately judge during remote operation, and achieve the purpose of remote automatic and intelligent control, thereby improving the unloading efficiency.

[0023] In addition, a control knob is connected to the input end signal of the idling processing module. The control knob is used to control the operation of the deflection control component 6. When the idling processing module determines that the material is caked or not in contact with the material taking head 2, the idling processing module sends the judgment result to the detection and analysis module. The detection and analysis module sends a reminder signal to the reminder module. The reminder module reminds the operator of the handheld remote intelligent controller 5 that the material taking head 2 is in an idling state by means of light and sound. At this time, the operator can actively control the deflection position of the material taking head 2 through the signal fed back by the reminder module. At this time, the operator can send the deflection direction and deflection angle signals to the detection and analysis module by rotating the control knob. At this time, the detection and analysis module wirelessly controls the operation of the deflection control component 6 through the remote data transmission module. The operation of the deflection control component 6 will control the material taking head 2 to deflect to the specified direction and angle, which is convenient for flexibly controlling the position of the material taking head 2 and improving the unloading efficiency of the material taking head 2.

[0024] In this embodiment, please refer to Figure 2 and Figure 3 , an upper pressure ring 9 and a lower pressure ring 8 are respectively sleeved on the middle part of the material taking head 2. A first driving member is installed on the material taking head 2. The output end of the first driving member is installed with a bidirectional screw rod 10. The threads arranged bidirectionally on the bidirectional screw rod 10 are respectively in threaded connection with the corresponding upper pressure ring 9 and lower pressure ring 8 to control the upper pressure ring 9 and the lower pressure ring 8 to move in the same or opposite directions. The input end of the remote data transmission module is signal-connected to the first driving member through wireless transmission. By setting the lower pressure ring 8 and the upper pressure ring 9, when the material taking head 2 rotates to disperse the material, the lower pressure ring 8 and the upper pressure ring 9 can increase the dispersion range of the material taking head 2 and improve the processing capacity of the material; and when the idling processing module determines that the material is caked or not in contact with the material taking head 2, it controls the material taking head 2 to deflect to increase its contact range with the material. When deflecting, when the idling processing module determines that the air pressure value fed back by the first air pressure sensor 21 has not returned to the normal air pressure value, at this time, the idling processing module sends a signal to strengthen the dispersion to the detection and analysis module. At this time, the detection and analysis module wirelessly controls the operation of the first driving member through the remote data transmission module. The first driving member controls the bidirectional screw rod 10 to rotate forward and reverse alternately, so as to control the lower pressure ring 8 and the upper pressure ring 9 to move in the vertical direction, reduce the contact dead angle between the rotation of the material taking head 2 and the caked material, and at the same time, when the lower pressure ring 8 and the upper pressure ring 9 come into contact, they will collide, which can synchronously drive the material taking head 2 to vibrate, thereby improving the dispersion effect of the material and further improving the dispersion effect of the caked material.

[0025] Such as Figure 1 and Figure 2As shown, a rotation control assembly 7 is installed on the transverse pipe 3. The output end of the rotation control assembly 7 is connected to the material taking head 2 to drive the material taking head 2 to rotate around its axis. By operating the rotation control assembly 7 to drive the material taking head 2 to rotate, the rotation of the material taking head 2 can be controlled to disperse the material, and at the same time, the material is wound into the material taking head 2, improving the discharging efficiency of the material. Embodiment 2

[0026] Different from Embodiment 1, in order to reduce the collision of the material taking head 2 during remote operation, as Figure 5 and Figure 6 shown, a material taking auger 17 is installed in the material taking head 2. A collision detection chamber 9 is fixed in the middle of the material taking detection chamber 11. The top central axis of the material taking auger 17 extends into the inner cavity of the collision detection chamber 9. The port of the material taking detection chamber 11 and the outer ring of the material taking auger 17 are sealed by a sealing ring 23. A second air pressure sensor 20 is installed in the inner cavity of the material taking detection chamber 11. The input end of the remote data transmission module is signal-connected to the second air pressure sensor 20 through a wireless transmission method. When the material taking head 2 discharges the material, it will contact the bulkhead in the cabin, especially when discharging at the edge of the cabin. At this time, when the material taking head 2 is subjected to a large external force on the side, the internal material taking auger 17 will be offset. The offset material taking auger 17 squeezes the inner cavity of the collision detection chamber 9. The second air pressure sensor 20 transmits the detected air pressure value to the detection and analysis module in real time through the remote data transmission module. The detection and analysis module compares the pressure value fed back by the second air pressure sensor 20 with the normal pressure value (the normal pressure value when the material taking auger 17 rotates normally is preset in the detection and analysis module). When the detection and analysis module determines that the pressure value fed back by the second air pressure sensor 20 is greater than the normal pressure value, it is determined that the material taking auger 17 is in an offset state, and it is determined that the material taking head 2 is subjected to an external force and there is a risk of collision with the side wall of the cabin. At this time, the detection and analysis module will send a reminder signal to the reminder module, and the reminder module will remind the operator holding the remote intelligent controller 5 of the risk of collision of the material taking head 2 by means of light and sound. At this time, the operator can actively control the deflection position of the material taking head 2 through the signal fed back by the reminder module, thereby reducing the collision risk.

[0027] In addition, the inner cavity of the collision detection chamber 9 can be divided into multiple detection chambers around the outer ring of the material taking auger 17, and a second air pressure sensor 20 is installed in each detection chamber. According to the increase in the air pressure value detected by the corresponding second air pressure sensor 20, it can be judged that the material taking auger 17 is offset to the corresponding position, and the offset direction of the material taking auger 17 can be judged more accurately, which is convenient for accurately judging the force direction of the material taking head 2 during remote operation and accurately adjusting the material taking head 2.

[0028] In this embodiment, as Figure 5As shown in the figure, a main auger 4 is installed in the middle of the vertical spiral pipe 1. A transfer wheel 18 is rotatably connected to the middle of the transverse pipe 3. The main auger 4 and the material-taking auger 17 are linked through the transfer wheel 18. By controlling the rotation of the main auger 4 to drive the rotation of the transfer wheel 18 and synchronously drive the rotation of the material-taking auger 17, the material is transferred into the transverse pipe 3 through the rotation of the material-taking auger 17, and is transferred towards the bottom of the main auger 4 through the transfer wheel 18, and is conveyed upward to the discharging place through the rotation of the main auger 4, achieving the purpose of automatic discharging. Embodiment III

[0029] Different from Embodiment II, since the length of the vertical spiral pipe 1 is usually long, when the vertical spiral pipe 1 is blocked, material accumulation is likely to occur, damaging the vertical spiral pipe 1 or the main auger 4 and causing damage to the equipment. To solve the above problems, please refer to Figures 5-8 , a drain plug opening 14 is provided at one end of the transverse pipe 3 close to the vertical spiral pipe 1. A sealing baffle plate 15 is vertically inserted at one end of the transverse pipe 3 close to the drain plug opening 14. A telescopic member 16 with an output end connected to the sealing baffle plate 15 is installed on the transverse pipe 3. When the vertical spiral pipe 1 is blocked, the telescopic member 16 can be controlled to work to drive the sealing baffle plate 15 to move upward, so that the blocked material is discharged through the drain plug opening 14, facilitating the maintenance of the vertical spiral pipe 1 and the main auger 4.

[0030] It is worth mentioning that a discharging detection chamber 12 is installed at the position corresponding to the bottom port of the vertical spiral pipe 1 on the transverse pipe 3. A sealing and pressing plate II 24 is provided between the bottom of the inner cavity of the vertical spiral pipe 1 and the inner cavity of the discharging detection chamber 12. A pressure sensor III 25 is installed in the inner cavity of the discharging detection chamber 12 to detect the air pressure value of the chamber formed by the sealing and pressing plate II 24 and the inner cavity of the discharging detection chamber 12. When the main auger 4 conveys the material upward and the vertical spiral pipe 1 is blocked, the blocked material fills the vertical spiral pipe 1 and increases the downward pressure on the sealing and pressing plate II 24. As Figure 8 At this time, the pressure sensor III 25 detects an increase in the air pressure value at its location, so that the blockage condition of the vertical spiral pipe 1 can be quickly detected.

[0031] In addition, a blockage handling module is also provided on the remote intelligent controller 5. The detection and analysis module is signal-connected to the blockage handling module. The input end of the remote data transmission module is respectively signal-connected to the telescopic member 16 and the air pressure sensor III 25 through a wireless transmission method. The blockage handling module is signal-connected to a blockage discharging button. When the screw unloader works to unload the materials in the cabin, the materials enter through the bottom of the material taking head 2 and enter the vertical screw pipe 1 through the transverse pipe 3. The materials are stably lifted upward through the vertical screw pipe 1. During this process, the air pressure sensor III 25 wirelessly transmits the detected air pressure value to the detection and analysis module in real time through the remote data transmission module. The detection and analysis module sends the air pressure value of the air pressure sensor III 25 to the blockage handling module for processing. The blockage handling module compares the air pressure value fed back by the air pressure sensor III 25 with a preset normal air pressure value (the normal air pressure value of the chamber where the air pressure sensor III 25 is located during normal unloading of the vertical screw pipe 1 is preset in the blockage handling module). When the blockage handling module determines that the air pressure value fed back by the air pressure sensor III 25 is greater than the preset normal air pressure value, it is determined that the vertical screw pipe 1 is in a blocked state. The blockage handling module sends the judgment result to the detection and analysis module, and the detection and analysis module sends a reminder signal to the reminder module. The reminder module reminds the operator holding the remote intelligent controller 5 that the vertical screw pipe 1 is in a blocked state by means of light and sound, facilitating the operator to timely understand the working state of the vertical screw pipe 1. After seeing the reminder signal sent by the remote intelligent controller 5, the operator sends an anti-blockage signal to the detection and analysis module by pressing the blockage discharging button. The detection and analysis module wirelessly controls the telescopic member 16 to work through the remote data transmission module, thereby controlling the opening of the blockage discharging port 14, enabling the materials gradually accumulated at the bottom of the vertical screw pipe 1 to be quickly discharged through the blockage discharging port 14, reducing the damage to the vertical screw pipe 1 and the main auger 4, and thus realizing the automatic and intelligent judgment of the blockage situation of the vertical screw pipe 1 and quickly processing it through remote control, improving the protection ability of the equipment.

[0032] In this embodiment, a pressure regulating pipe I 13 connected to its inner cavity is installed on the material taking detection chamber 11, and a pressure regulating pipe II 26 connected to its inner cavity is installed on the discharging detection chamber 12. Control valves are installed on both the pressure regulating pipe I 13 and the pressure regulating pipe II 26. Different pressures of gas are filled into the corresponding chambers of the material taking detection chamber 11 and the discharging detection chamber 12 through the pressure regulating pipe I 13 and the pressure regulating pipe II 26, so as to adjust the corresponding initial air pressure values. When unloading different types of materials, the sensitivity of the detection results of the corresponding air pressure sensor I 21 and air pressure sensor III 25 can be improved, and the accuracy of the detection results can be improved.
