Description

Technical Field

[0001] This utility model relates to the field of operation and transportation technology, and in particular to a laser coal panning device. Background Technology

[0002] Coal is the most important raw material for thermal power plants, accounting for approximately 70% to 80% of their costs. With the establishment of national environmental regulations, enclosed coal yards are gradually becoming the mainstream trend for thermal power plants. Currently, there are two types of enclosed coal yards: air-supported membrane structures and steel structures. Steel structure enclosed coal yards mainly use multiple fixed laser coal inventory monitors installed on both sides of the walkway. These fixed laser coal inventory monitors are primarily installed below the walkway. Routine maintenance and repairs, such as cleaning the laser lenses and checking the wiring, require manual high-altitude work to disassemble the monitors. Since the laser coal inventory monitors, including the installation and protection mechanisms, weigh tens of kilograms, manual disassembly is labor-intensive and has a low safety factor, making routine maintenance and repairs difficult. For example, Chinese Patent Publication No. CN213397173U discloses a U-shaped monorail mobile laser coal inventory device for enclosed coal yards. The technical solution is as follows: This utility model relates to a U-shaped monorail mobile laser coal inventory device for enclosed coal yards, including a U-shaped monorail 1 erected on the steel structure roof of the coal yard. A coal inventory trolley is invertedly mounted on the U-shaped monorail for moving along the track route to inventory the entire coal yard. The coal inventory trolley is equipped with a coal inventory device for performing a full-coverage scan of the entire coal yard. By using a U-shaped monorail with an omnidirectional gimbal laser scanner, during coal inventory scanning, by selecting two different modes—inner circle scanning and outer circle scanning—the entire internal and external area covered by the U-shaped rail can be scanned during one round trip of the trolley. This not only removes the limitations of the coal yard conditions for the laser coal inventory device, but also allows the U-shaped monorail to be laid in sections according to the actual size and scanning range of the enclosed coal yard, saving track costs, reducing installation difficulty, and enhancing the versatility of the coal inventory device. However, the aforementioned U-shaped monorail mobile laser coal storage device for enclosed coal yards has a complex structure, is inconvenient to install and disassemble, and is difficult to maintain.

[0029] See Figure 1-2 As shown, a laser coal counting device mounting mechanism includes a walkway 110, a longitudinal drive mechanism, a transverse drive mechanism, and a coal counting device 101. The longitudinal drive mechanism is fixed in parallel on one side of the walkway 110. The transverse drive mechanism is slidably mounted on the longitudinal drive mechanism on both sides. The coal counting device 101 is slidably mounted on the transverse drive mechanism via a coal counting device mounting plate 102.

[0030] like Figure 1 In one embodiment shown, Figure 1This is a schematic diagram of the installation mechanism for a laser coal reconciliation device according to this utility model. This utility model provides a laser coal reconciliation device installation mechanism that is simple in structure, easy to install, convenient to maintain, and has good safety, significantly solving the problems of complex structure, inconvenient installation and disassembly, and difficulty in maintenance in the prior art. The device of this utility model mainly includes a walkway 110, a longitudinal drive mechanism, a transverse drive mechanism, and a coal reconciliation device 101. Two longitudinal drive mechanisms are fixed in parallel on one side of the walkway 110, ensuring the stability and load-bearing capacity of the overall structure.

[0031] The longitudinal drive mechanism consists of a longitudinal drive motor 108 and a longitudinal linear module 106. The longitudinal linear module 106 is equipped with a longitudinal linear module bracket 107 and a longitudinal linear module slider, allowing two sets of longitudinal linear module brackets 107 to be fixed in parallel on the walkway 110. Two longitudinal drive motors 108 are mounted on the top of the brackets. This parallel fixed linear module bracket and slider structure not only improves the stability and accuracy of the drive mechanism but also ensures the smoothness of the equipment during longitudinal movement, thereby extending the service life of the equipment.

[0032] The lateral drive mechanism consists of a lateral drive motor 105 and a lateral linear module 103. The lateral linear module 103 is equipped with a lateral linear module bracket 104 and a lateral linear module slider. The lateral drive motor 105 is mounted on the end of the bracket 104 furthest from the catwalk 110. This layout optimizes space utilization, reduces interference with the catwalk, and ensures the stability and reliability of lateral movement through a balanced lateral drive design.

[0033] The coal inventory unit 101 is slidably mounted on the transverse drive mechanism via a coal inventory unit mounting plate 102. Both ends of the mounting plate 102 are slidably mounted on two transverse drive modules 103 via transverse linear module sliders on both sides, with the coal inventory unit 101 fixed below the mounting plate 102. Furthermore, a coal inventory unit rotating platform is provided between the coal inventory unit 101 and the mounting plate 102. This rotating platform is installed at the center of the mounting plate 102 and can achieve 360-degree rotation of the coal inventory unit. This design of the coal inventory unit improves the laser scanning coverage of the coal inventory unit, reduces the number of coal inventory units required in the coal yard, lowers construction costs, and greatly improves the overall stability and ease of operation of the equipment.

[0034] The transverse linear module support 104 is slidably mounted on the longitudinal linear module 106 via the longitudinal linear module slider, achieving coordinated operation of the longitudinal and transverse drive mechanisms and ensuring the synchronization and accuracy of the coal gauge during longitudinal and transverse movement. Simultaneously, both the transverse linear module 103 and the longitudinal linear module 106 are equipped with limit devices at their ends to prevent excessive movement of the drive mechanisms, thereby protecting the equipment from mechanical damage and ensuring the safety and stability of the system operation.

[0035] A control box 109 is installed on one side of the walkway 110, and the power lines for both the longitudinal drive motor 108 and the transverse drive motor 105 are connected to this control box. The centralized control system simplifies electrical connections and management, ensures synchronous operation of the drive motors, and improves the overall reliability and maintainability of the system. Centralized control not only optimizes the spatial layout but also reduces wiring clutter and potential electrical faults, further enhancing system safety.

[0036] In one embodiment, this utility model is applied to a laser coal inventory device installation mechanism for a steel-structured enclosed coal yard, including a local control box, a longitudinal drive mechanism, a transverse drive mechanism, a coal inventory device mounting plate, a coal inventory device, and a walkway. The longitudinal drive mechanism includes a longitudinal drive motor, a longitudinal linear module, and a longitudinal linear module support; the transverse drive mechanism includes a transverse drive motor, a transverse linear module, and a transverse linear module support.

[0037] There are two sets each of the longitudinal drive mechanism and the transverse drive mechanism, fixed in parallel on one side of the walkway. The longitudinal linear module bracket is fixed to the walkway by welding and screws; the transverse linear module bracket is fixed to the longitudinal linear module by the slider of the longitudinal linear module. The longitudinal linear module and the transverse linear module are fixed to the longitudinal linear module bracket and the transverse linear module bracket respectively by screws. The coal meter mounting plate is fixed to the two transverse drive modules by the slider of the transverse linear module.

[0038] The longitudinal drive motor is fixed to one end of the longitudinal linear module and drives the transverse drive mechanism to move up and down; the transverse drive motor is fixed to one end of the transverse linear module and drives the coal meter mounting plate to move horizontally back and forth.

[0039] The laser coal counting device is fixed to the coal counting device mounting plate with screws. In this embodiment, this part can be selectively installed or removed from the coal counting device rotating platform.

[0040] The local control box is installed on the walkway and is used to control the movement direction and start / stop of the longitudinal drive motor and the transverse drive motor locally.

[0041] The power lines for the longitudinal drive motor and the transverse drive motor are connected to the local control box.

[0042] The stepper motor is equipped with a brake, so it will not move due to gravity or vibration after it has moved to the target point.

[0043] In this embodiment, the working principle of the present invention is as follows: the local control box utilizes the polarity reversal and switching characteristics of the drive motor power supply to synchronously control the up-and-down movement and start-and-stop of two sets of longitudinal drive mechanisms, as well as the forward-and-backward movement and start-and-stop of two sets of transverse drive motors.

[0044] In this embodiment, the drive motor is an 86 stepper motor, model 86CM120-BZ; the horizontal linear module uses a dual-guide rail linear module CNC heavy-duty high-precision high-speed ball screw slide, model KR30 square rail, with an effective stroke of 600mm; the vertical linear module also uses a dual-guide rail linear module CNC heavy-duty high-precision high-speed ball screw slide, model 250A steel concave plate, with an effective stroke of 800mm.

[0045] The laser coal counter mounting mechanism of this utility model has several significant advantages, comprehensively improving the performance and user experience of the equipment. Firstly, the mounting mechanism has a simple structure. Through a rational design, the longitudinal and transverse drive mechanisms are fixed in parallel on one side of the walkway 110, reducing the number of components and complexity. This simplified structure not only reduces manufacturing and installation costs but also shortens installation time and improves installation efficiency. Secondly, the ease of installation is significantly enhanced. The longitudinal drive mechanism includes two longitudinal drive motors 108 and a longitudinal linear module 106. Through the parallel fixed bracket 107 and slider design, the smooth longitudinal movement of the coal counter 101 is achieved. The transverse drive mechanism also adopts a combination of a transverse drive motor 105 and a transverse linear module 103, optimizing the spatial layout and reducing interference with the walkway 110. This modular design makes installation and disassembly easier, allowing for quick adjustment or replacement of relevant components as needed during use, greatly facilitating equipment maintenance and repair.

[0046] Furthermore, the stability and accuracy of the equipment have been significantly improved. The parallel fixing structure of the longitudinal and transverse linear module supports and the slider ensures the stability of the drive mechanism during movement, preventing equipment swaying and deviation. Simultaneously, the limit device effectively prevents excessive movement of the drive mechanism, protecting the equipment from mechanical damage and extending its service life. This high-precision drive system not only improves the measurement accuracy of the coal panning instrument but also ensures the reliability of the equipment during long-term operation.

[0047] In terms of safety, the centralized installation design of the control box 109 allows for centralized management of the power lines of the longitudinal drive motor 108 and the transverse drive motor 105, reducing the complexity of electrical connections and lowering the risk of electrical faults. Simultaneously, the brake function equipped on the stepper motors prevents accidental movement due to gravity or vibration after the equipment has been moved to the target position, further ensuring safety during operation.

[0048] The ease of operation and work efficiency have also been significantly improved. The coal inventory meter mounting plate 102 is connected to the horizontal drive module 103 through the horizontal linear module slider. Combined with the 360-degree rotation function of the coal inventory meter rotating gimbal, the coal inventory meter 101 can achieve comprehensive rotation operation, improve the laser scanning coverage of the coal inventory meter, reduce the number of coal inventory meters required in the coal yard, reduce construction costs, and greatly improve the overall stability and ease of operation of the equipment.

[0049] Furthermore, the centralized control system significantly improves the overall reliability and maintainability of the system. By centrally managing the power supply and control signals of the drive motors through the control box 109, synchronous operation of the longitudinal and lateral drive mechanisms is ensured, avoiding coordination problems that might arise from independent control. Centralized control not only optimizes the spatial layout and reduces cable clutter, but also facilitates system monitoring and troubleshooting, improving equipment management efficiency and operational stability.

The transverse drive motor 105 is installed at the end of the transverse linear module bracket 104 away from the walkway 110. The coal inventory device 101 can smoothly slide on the transverse drive mechanism through the cooperation of the coal inventory device mounting plate 102 and the transverse drive mechanism.

[0051] In addition, a control box 109 is provided on one side of the walkway 110. The power lines of the longitudinal drive motor 108 and the transverse drive motor 105 are both connected to the control box 109 to achieve centralized control. To ensure the safety and stability of the equipment operation, limit devices are installed at the ends of the transverse linear module 103 and the longitudinal linear module 106 to prevent excessive movement of the drive mechanism.

Both ends of the mounting plate 102 are connected to two transverse linear modules 103 via sliders, and the coal counting device 101 is fixed below the mounting plate. Furthermore, a rotating platform is provided between the coal counting device and the mounting plate, supporting 360-degree rotation of the coal counting device.

[0056] In order to achieve coordinated operation of the longitudinal and transverse drive mechanisms, the transverse linear module bracket 104 is slidably mounted on the longitudinal linear module 106 via the longitudinal linear module slider. At the same time, limit devices are installed at the ends of both the transverse and longitudinal linear modules to prevent excessive movement of the drive mechanism, protect the equipment from mechanical damage, and ensure the safety and stability of the system operation.

[0057] Regarding the control system, a control box 109 is installed on one side of the walkway 110. The power lines of both the longitudinal drive motor 108 and the transverse drive motor 105 are connected to this control box for centralized control.
