Description

Technical Field

[0001] The present invention relates to the technical field of stacking mechanical equipment, in particular to a radio frequency admittance type high-precision walking positioning stacking machine. Background Art

[0002] In the industrial sector, stackers are key equipment in material handling, widely used in industries such as power generation, ports, and mining. With the expansion of industry scale and the increasing demand for refined production, the shortcomings of traditional stackers in terms of travel and positioning have become increasingly prominent.

[0003] In the electric power industry, power plants need to efficiently process large quantities of coal. Positioning deviations in traditional stackers often lead to messy coal stacking, affecting retrieval efficiency, increasing rummaging costs, and easily causing the risk of pile collapse due to uneven stacking, threatening production safety. At port terminals, the throughput of bulk cargo such as ore, sand and gravel is huge. Inaccurate positioning of stackers will cause the cargo to be stacked beyond the planned area, occupying additional space, interfering with the loading and unloading process, and restricting the terminal's throughput capacity. In the mining industry, different ores need to be stacked in different categories. Traditional stackers are difficult to accurately position, resulting in material mixing and affecting the quality and efficiency of subsequent processing. Therefore, a mechanical equipment was born that uses radio frequency admittance technology, combined with an optimized system structure and control algorithm, to achieve high-precision and stable walking positioning of stackers under complex working conditions.

[0004] However, in daily use, when a radio frequency admittance stacker moves on a guide rail to a designated position, the weight of the equipment and the material creates inertia. Over time, this inertia damages the connection between the rail and the stacker, reducing positioning accuracy, leading to positioning errors and shortening service life. Therefore, a radio frequency admittance high-precision walking positioning stacker was proposed to address this issue. Summary of the Invention

[0018] (3) Beneficial effects

[0019] Compared with the existing technology, the present invention provides a radio frequency admittance type high-precision walking positioning stacker, which has the following beneficial effects:

[0020] 1. This radio frequency admittance type high-precision walking positioning stacker adopts a buffer part to effectively reduce the inertia damage of the stacker during travel. During the movement of the stacker, through the cooperation of the cleaning part and the positioning part, when it approaches the specified position, the air in the cylinder is filled into the air bag through the air injection pipe, causing the air bag to expand and push the buffer pad to press the guide rail, achieving braking and buffering, reducing inertia damage to the connection between the track and the stacker, and extending the service life of the equipment.

[0021] 2. This RF admittance-type high-precision walking positioning stacker uses a cleaning unit to clean the detection tool in real time after the stacker is positioned. When the stacker moves to a specific position, the buckle connects with the hook plate, driving the sliding arm and support arm to move, so that the piston rod is pushed in the U-shaped air jet tube and air cylinder. The U-shaped air jet tube sprays dust to the detection probe, ensuring the accuracy of RF admittance detection, avoiding the influence of dust and other factors on the detection results, and ensuring the reliability of positioning.

[0022] 3. This RF admittance type high-precision walking positioning stacker uses RF admittance technology to achieve precise positioning. The positioning part is equipped with multiple detection probes, which cooperate with the RF detection elements of the walking part. Utilizing the principle of RF admittance, when the RF detection elements pass through the detection probes, the system's capacitance, inductance and other parameters change, which manifests as admittance changes, and then accurately feedbacks the coordinate position of the stacker in the material yard, solving the problem of large positioning deviation of traditional stackers and improving the accuracy and efficiency of stacking.

[0023] 4. This radio frequency admittance type high-precision walking positioning stacker adopts the coordinated work of various components. For example, the positioning part, walking part, cleaning part and buffer part cooperate with each other to realize positioning, cleaning and buffering functions. Multiple components of the positioning part, such as the positioning plate, detection probe, buckle, card block, infrared sensor receiving end, etc., work together to ensure the accuracy of positioning. The protective plate of the walking part not only protects the stacker connector, but also provides an installation position for other components, enhancing the overall stability and functionality of the equipment.

[0033] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0034] See also Figure 1-8 The present invention provides a technical solution: a radio frequency admittance high-precision walking positioning stacker, including a stacker 1, a track base plate 2 and a guide rail 3. The positioning part 4 of this case is installed on the track base plate 2, which is used for radio frequency admittance positioning of the stacker 1. The walking part 5 of this case is installed on the stacker 1, which is used to install cleaning tools and inertia protection tools and follow the stacker 1 to walk along the guide rail 3. The cleaning part 6 of this case is installed on the walking part 5, which is used to clean the dust on the detection tool in real time after the stacker 1 is positioned. The buffer part 7 of this case is installed in the connector of the stacker 1, which is used for inertia protection when the stacker 1 is walking. The guide rail 3 is fixedly connected to the top middle of the track base plate 2. The connector of the stacker 1 is a U-shaped structure, and the stacker 1 is slidably connected to the guide rail 3 through the connector.

[0035] In this embodiment, in order to more accurately locate the working position of the stacker 1 in the material yard, the positioning part 4 of this case includes a positioning plate 41, and a detection probe 42 is installed on one side of the top of the positioning plate 41, and a YK-KSPDN probe is adopted. Two receiving grooves 43 are symmetrically provided on the other side of the top of the positioning plate 41, and the two receiving grooves 43 are hinged with buckles 44. The two buckles 44 are symmetrically arranged with each other and are both U-shaped structures. The hinged end of each buckle 44 is elastically connected to the inner wall of the receiving groove 43 in which it is located. A torsion spring is elastically connected, and the torsion spring flips the buckle 44 to the outside of the receiving groove 43 through torsion. The inner walls of the two receiving grooves 43 are provided with slide grooves, and the inner wall of each slide groove is slidably connected with a card block 45 and is elastically connected by a spring. Two red The external sensor receiving end 46 uses BPW34 to convert infrared light into electrical signals for detection. The ends of the two blocks 45 respectively press the buckles 44 adjacent to themselves. Electromagnets are installed on the inner walls of the two slides. Each infrared sensor receiving end 46 is electrically connected to the electromagnet adjacent to itself, and the electrical signal is used to control the magnetic force of the electromagnet, thereby actively controlling the sliding of the block 45 and releasing the buckle 44. There are six positioning parts 4, and every three positioning parts 4 are arranged in an array on one side of the top of the track base plate 2. The positioning parts 4 on both sides of the top of the track base plate 2 are symmetrically arranged. In this case, the positioning parts 4 are used in conjunction with the guide rail 3 and the track base plate 2, and according to the actual use requirements of the material yard, two or more sets of supporting equipment are used to lay the guide rail 3 length and the same amount of positioning parts 4.

[0036] It is worth noting that the use position of the stacker 1 is accurately positioned by multiple positioning parts 4 distributed on both sides of the guide rail 3. The walking part 5 of this case includes a protective plate 51, which is used to prevent dust and material splashing and protect the connector of the stacker 1. The protective plate 51 is an L-shaped structure. The top of one end of the protective plate 51 is fixedly connected to a connector 52, and the side wall of the other end of the protective plate 51 is fixedly connected to a connecting plate 53. The protective plate 51 is fixedly connected to one side of the connector of the stacker 1 through the connector 52 and the connecting plate 53. Two radio frequency detection elements 54 are installed on one end of the protective plate 51, using Cap The e-11a universal electrical detection element will change its electric field distribution when passing through the detection probe 42, which will cause changes in the system's capacitance, inductance and other parameters, and ultimately manifest as a change in admittance. Two RF detection elements 54 are located on both sides of the connector 52. The two RF detection elements 54 are aligned with the two detection probes 42 on the same side. When the two RF detection elements 54 are aligned with the two detection probes 42, their coordinate positions in the material yard can be accurately fed back to the cloud. Two sliding holes 55 are symmetrically opened at one end of the protective plate 51, and the two sliding holes 55 are located on both sides of the connector 52.

[0037] In order to further improve the accuracy of the detection probe 42, the cleaning part 6 of this case includes a mounting body 61, which is mounted on one side of the bottom of the protective plate 51. Two sliding arms 62 slide through the mounting body 61. The ends of the two sliding arms 62 are fixedly connected with a hook plate 63. The hook plate 63 extends out of one side of the mounting body 61. After the buckle 44 is released and opened, it will flip and buckle the hook plate 63 to form a soft connection. The other end of the two sliding arms 62 is fixedly connected with a support arm 64. A spring 2 65 is elastically connected between the support arm 64 and the mounting body 61. A U-shaped air jet 66 is installed in the mounting body 61. Both ends of the U-shaped air jet 66 extend out of the other side of the mounting body 61. One side of the extended end of the U-shaped air jet 66 slides inward. It is movably connected with a piston rod 1 67, and a one-way valve is provided on the extended end of the U-shaped jet tube 66. The other extended end of the U-shaped jet tube 66 is tilted, and the support arm 64 slides through the sliding hole 55 on the same side and extends upward. The extended end of the support arm 64 is fixedly connected with a piston rod 2 68. A gas cylinder 69 is installed in the connecting body 52, and one end of the gas cylinder 69 extends to the outside of the connecting body 52 and is slidably connected to the piston rod 2 68. A one-way valve is provided on the extended end of the gas cylinder 69, and the other end of the gas cylinder 69 is connected and installed with an air injection pipe 610, which movably passes through the outside of the connecting body 52. ​​An infrared sensor transmitting end 611 is installed at the bottom of the mounting body 61, and a BPW34 series matching infrared transmitting tube is adopted.

[0038] In order to provide timely braking and buffering protection when the stacker 1 is positioned and reduce inertia damage, the buffer portion 7 in this case includes a buffer pad 71, which is hinged to the inner wall of the ear end of the connector on one side of the stacker 1. An airbag 72 is installed between the inner wall of the ear end of the connector of the stacker 1 and the buffer pad 71. The through end of the air injection pipe 610 continues to penetrate the connector of the stacker 1 and is connected to the airbag 72. The airbag 72 is further expanded by air injection, thereby pushing the buffer pad 71 to press the guide rail 3 for braking and buffering.

[0039] It is worth noting that the infrared sensor transmitting end 611 and the infrared sensor receiving end 46 are on the same vertical line and are electrically connected. The infrared sensor transmitting end 611 will generate an electrical signal through the infrared sensor receiving end 46. The buckle 44 is on the same vertical line as the hook plate 63 on the same side. After the buckle 44 is released, it will flip over and buckle on the hook plate 63. There are two cleaning parts 6 and two buffer parts 7. The other cleaning part 6 is symmetrically installed on the other side of the bottom of the protective plate 51. The other buffer part 7 is installed on the other cleaning part 6. The walking part 5 and the two cleaning parts 6 and the two buffer parts 7 together constitute an inertial protection mechanism. There are two inertial protection mechanisms, and the other inertial protection mechanism is symmetrically installed on the other side of the connector of the stacker 1.

[0040] The working principle is that the stacker 1 is externally installed with walking wheels, motors and other components for movement control. The transmission system of the stacker 1 transports materials, and the transmission system rotates in position through the motor controller. These are all existing technologies and will not be elaborated in this case. When the stacker 1 moves, its connector moves on the guide rail 3, such as moving the stacker 1 forward to the two detection probes 42. According to the structure of this case, there must be an empty detection probe 42 between the two detection probes 42. The empty detection probe 42 is used to build a temporary buffer system.

[0041] When the stacker 1 moves forward to the two designated detection probes 42, an infrared sensor receiving end 46 at the rear position on the vacant detection probe 42 at that position is turned on, and the other infrared sensor receiving ends 46 are turned off. The mounting body 61 on the front side of the protective plate 51 must first pass through the vacant detection probe 42. At the same time, the infrared sensor transmitting end 611 interacts with the infrared sensor receiving end 46 at the rear position to generate an electrical signal. The electromagnet intermittently absorbs the card block 45 once, releases the buckle 44, and flips it to more than ninety degrees through the torsion spring. At this time, the mounting body 61 is slightly away from the vacant detection probe 42, and the buckle 44 can be buckled on the hook plate 63, thereby pulling the hook plate 63 when the stacker 1 continues to move, causing the sliding arm 62 to drive the support arm 64 to slide, thereby driving the piston rod 1 67 and the piston rod 2 68 to synchronously advance inside the U-shaped jet pipe 66 and the air cylinder 69, spraying air from the U-shaped jet pipe 66 and toward the detection probe in front. The measuring probe 42 is dust-cleaned to ensure the detection accuracy during RF admittance, and air is pushed out from the air cylinder 69 along the air injection pipe 610 to fill the air bag 72 to make it further expand, and then squeeze the buffer pad 71 to flip and abut the inner wall of the guide rail 3, thereby completing braking and buffering, reducing the structural damage caused by inertia, and playing a role in buffering protection. When the RF detection element 54 on the front side of the protective plate 51 is aligned with the front detection probe 42, it stops moving and performs temporary buffering when passing through the spare detection probe 42. Inertia protection measures are taken in advance to improve safety. After the stacker 1 stops moving, the RF detection element 54 on the rear side of the protective plate 51 must be aligned with the rear detection probe 42, and a corresponding buckle 44 on the middle spare detection probe 42 pulls the hook plate 63 to slide, and the piston rod 1 67 and the piston rod 2 68 are both pushed into the corresponding U-shaped injection tube 66 and air cylinder 69, thereby completing precise positioning.

[0042] On the contrary, when the stacker 1 moves backward, the mounting body 61 passes the spare detection probe 42, the spring 2 65 pushes the support arm 64 to reset, the piston rod 2 68 sucks a part of the gas in the airbag 72 to reduce the expansion degree, the mounting body 61 squeezes the buckle 44 to flip it into the storage groove 43, and makes the buckle 44 squeeze the block 45, and under the elastic force of the spring 1, the block 45 re-engages the buckle 44 to reset, thereby restoring the initial posture of each positioning part 4. During the next positioning movement, the above steps are continued to be used in conjunction with the temporary buffer system for precise positioning.
