Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] As introduced in the background art, there are deficiencies in the prior art. To solve the above technical problems, the present application proposes a grinding device for energy-saving transformation of thermal power plants.

[0033] Example 1: Please refer to Figures 1 - 8, a grinding device for energy-saving transformation of thermal power plants, a workbench 1, a grinding mechanism 3 is arranged on the top of the workbench 1. The grinding mechanism 3 includes an electric telescopic rod 31, a first motor 32 and a grinding wheel 33. An adjusting mechanism 4 is arranged on the outer side of the electric telescopic rod 31 for adjusting the position of the grinding mechanism 3. The adjusting mechanism 4 includes a stabilizing plate 49, and the adjusting mechanism 4 is arranged on the outer side of the stabilizing plate 49. A cleaning mechanism 5 is arranged on the outer side of the stabilizing plate 49;

[0034] A clamping mechanism 6 is arranged on the top of the workbench 1. The clamping mechanism 6 includes a fixing plate 61. A moving mechanism 7 is arranged inside the workbench 1, and the bottom of the fixing plate 61 is fixedly connected above the moving mechanism 7 to move and adjust the position of the clamping mechanism 6.

[0035] Furthermore: When it is necessary to grind the relevant workpieces of the thermal power plant, the operator starts the grinding mechanism 3 through the controller 2. The electric telescopic rod 31 adjusts its own length according to the thickness of the workpiece, drives the first motor 32 installed on its outer side and the grinding wheel 33 connected to the output end of the first motor 32 to rise or fall, so that the grinding wheel 33 reaches the appropriate grinding height. Subsequently, the first motor 32 is started, and the output shaft rotates at a high speed, driving the grinding wheel 33 to rotate at a high speed to grind the workpiece placed on the workbench 1. The operator can adjust the telescopic amount of the electric telescopic rod 31 again through the controller 2 according to the actual grinding requirements, and flexibly change the position and grinding force of the grinding wheel 33.

[0036] Specifically: The combined design of the electric telescopic rod 31 and the first motor 32 brings great flexibility to the grinding operation. In the actual working conditions of thermal power plants, different parts have different shapes, sizes and thicknesses. The electric telescopic rod 31 can quickly adjust the vertical height of the grinding wheel 33 under the precise command of the controller 2, and the accuracy can reach the millimeter level, ensuring that the grinding wheel 33 always maintains the best distance from the surface of the workpiece to be ground. For example, for thin and complex-shaped parts such as steam turbine blades, the electric telescopic rod 31 can accurately position the grinding wheel 33 to avoid over-grinding or under-grinding. At the same time, the first motor 32 has the characteristics of high speed and high torque, and can adjust the speed according to the workpiece material (such as metal, alloy, etc.), and the range is usually 1000-5000 revolutions per minute to achieve efficient grinding. The coordinated work of this motor and the telescopic rod greatly improves the work efficiency and reduces the repeated debugging time caused by poor equipment adaptability compared with traditional grinding equipment with a fixed height.

[0037] It should be noted that: The grinding wheel 33 is designed with a quick-change structure to adapt to various different types of grinding requirements. In the equipment maintenance of thermal power plants, various tasks may be involved, such as removing rust, grinding smooth surfaces, and repairing worn parts. Through simple tools, the operator can replace the grinding wheel 33 with different materials and grit sizes within a short time (usually not exceeding 5 minutes). For example, a grinding wheel is used for rough grinding to remove thick rust layers, and a sandpaper wheel is used for fine grinding to achieve a mirror finish. This diverse selection and quick-change feature enable a grinding device to handle the grinding work of various equipment parts in thermal power plants, reducing the equipment procurement cost and improving the versatility of the equipment.

[0038] Embodiment 2: Refer to Figures 1 - 8 , different from the above Embodiment 1, a controller 2 is fixedly connected to the outside of the workbench 1, a first motor 32 is fixedly connected to the outside of the electric telescopic rod 31, an output end of the first motor 32 is fixedly connected to a grinding wheel 33, and the grinding wheel 33 is located above the workbench 1.

[0039] Embodiment 3, refer to Figures 1 - 8 , different from the above Embodiment 2, a stabilizing plate 49 is fixedly connected to the top of the workbench 1, and a second motor 41 is fixedly connected to the outside of the stabilizing plate 49. An output end of the second motor 41 is fixedly connected to a rotating shaft 42, a gear 43 is fixedly connected to the outside of the rotating shaft 42, connecting rods 44 are fixedly and symmetrically connected to the outside of the stabilizing plate 49, a sliding groove 45 is fixedly connected to the outside of the connecting rod 44, a toothed plate 46 is slidably connected to the inside of the sliding groove 45, a moving groove 47 is formed in the side wall of the sliding groove 45, and a moving block 48 is arranged outside the sliding groove 45.

[0040] Embodiment 4, refer to Figures 1 - 8 , different from the above Embodiment 3, the rotating shaft 42 passes through the inside of the stabilizing plate 49, the gear 43 is rotatably connected to the outside of the stabilizing plate 49 through the rotating shaft 42, and the sliding groove 45 is fixedly connected to the outside of the stabilizing plate 49 through the connecting rod 44.

[0041] Embodiment 5, refer to Figures 1 - 8 , different from the above Embodiment 4, the top of the toothed plate 46 is meshed with the bottom of the gear 43, one side of the moving block 48 is fixedly connected to the outside of the toothed plate 46 through a sliding rod, and the sliding rod is slidably connected to the inside of the moving groove 47. The other side of the moving block 48 is fixedly connected to the outside of the electric telescopic rod 31.

[0042] Furthermore: The adjustment mechanism 4 adopts the transmission mode of the gear 43 and the toothed plate 46, realizing the precise positioning of the grinding mechanism 3 in the horizontal direction. The rotation speed of the second motor 41 can be precisely controlled. With the precise meshing of the gear 43 and the toothed plate 46, the movement accuracy can reach 0.1 mm. This high-precision positioning is particularly important in tasks such as grinding the inner wall of the pipeline in a thermal power plant, which can ensure that the grinding wheel 33 accurately covers specific positions inside the pipeline, avoiding damage to the pipeline structure caused by grinding deviation. At the same time, this transmission mode has high stability. Even in the state of continuous working for a long time, it can ensure the accuracy of the position adjustment of the grinding mechanism 3, reducing the grinding quality problems caused by position deviation. Based on the design of the existing adjustment mechanism 4, it can be further expanded to have a multi-directional adjustment function. For example, a rotatable joint structure is added to the stabilizing plate 49, enabling the entire adjustment mechanism 4 to rotate at a certain angle on the horizontal plane, thereby realizing multi-angle grinding of workpieces with irregular shapes. This expansion will enable the grinding device to better adapt to the grinding requirements of complex-shaped parts in a thermal power plant, such as some connectors with special angles, special-shaped radiators, etc., greatly broadening the application range of the device.

[0043] Embodiment Six. Refer to Figures 1 - 8 , which is different from the above Embodiment Five in that the cleaning mechanism 5 includes a connecting rod 51. A first triangular block 52 is fixedly connected to the outside of the connecting rod 51. A lifting groove 53 is opened in the inner wall of the stabilizing plate 49. A limiting rod 54 is slidably connected inside the lifting groove 53. A reset spring 55 is fixedly connected to the bottom of the limiting rod 54. A running block 56 is fixedly connected to the outside of the limiting rod 54. An extrusion rod 57 is fixedly connected inside the running block 56. A second triangular block 58 is fixedly connected to the top of the extrusion rod 57. An elastic airbag box 59 is fixedly connected to the outside of the stabilizing plate 49. An air outlet plate 510 is fixedly connected to the outside of the elastic airbag 59. The first triangular block 52 and the second triangular block 58 are in the same plane and are in a closely attached state. The air outlet plate 510 is located on the top of the workbench 1.

[0044] Furthermore: The automatic cleaning function of the cleaning mechanism 5 is of great significance in the working environment of a thermal power plant. The dust generated during the grinding process not only pollutes the working area but also may pose a hazard to the respiratory system of the operators. At the same time, the accumulation of dust also has a certain fire hazard. The cleaning mechanism 5 blows out gas through the elastic airbag box 59 and the air outlet plate 510 to clean the dust, which can keep the top of the workbench 1 clean in real time and reduce the diffusion of dust in the workshop. Through actual testing, the cleaning mechanism 5 can effectively reduce the dust concentration in the workshop by more than 80%, providing a safer and healthier working environment for the operators.

[0045] Embodiment Seven. Refer to Figures 1 - 8, different from the sixth embodiment above, the fixing plates 61 are installed and symmetrically distributed above the workbench 1. An installation frame 62 is fixedly connected to the outside of the fixing plates 61. A hydraulic cylinder 63 is fixedly connected to the inside of the installation frame 62. A piston rod 64 is fixedly connected to the outside of the hydraulic cylinder 63. A pushing disk 66 is fixedly connected to the outside of the piston rod 64. A rotating rod 65 is arranged outside the installation frame 62. A transmission rod 67 is rotatably connected to the inside of the rotating rod 65. A clamping plate 68 is fixedly connected to the outside of the transmission rod 67.

[0046] Embodiment Eight. Refer to Figures 1 - 8 , different from the seventh embodiment above, the piston rod 64 passes through the inside of the installation frame 62. The rotating rods 65 are symmetrically distributed outside the installation frame 62. The connection between the transmission rod 67 and the clamping plate 68 is fixedly connected inside the pushing disk 66.

[0047] Embodiment Nine. Refer to Figures 1 - 8 , different from the eighth embodiment above, the moving mechanism 7 includes a bidirectional motor 71. An output end of the bidirectional motor 71 is fixedly connected to a lead screw 72. A ferrule 73 is threadedly connected to the outside of the lead screw 72. A extension rod 74 is fixedly connected to the top of the ferrule 73. A conduction groove 75 is formed inside the workbench 1. The bidirectional motor 71 is fixedly connected inside the workbench 1, and the output ends of the bidirectional motor 71 are in opposite directions. The extension rod 74 is slidably connected inside the conduction groove 75, and the top of the extension rod 74 is fixedly connected to the bottom of the fixing plate 61.

[0048] Furthermore: The clamping mechanism 6 provides clamping force through the hydraulic cylinder 63. The pressure of the hydraulic cylinder 63 can be precisely adjusted through the controller 2, usually in the range of 0 - 10 MPa, to adapt to the clamping requirements of workpieces with different materials, shapes, and sizes. For workpieces with softer textures, the clamping force can be reduced to avoid damage to the workpiece surface; for large and heavy workpieces, the clamping force is increased to ensure stable clamping. At the same time, the design of the rotating rod 65 and the transmission rod 67 enables the clamping plate 68 to adapt to the shape of the workpiece. Even if the surface of the workpiece is uneven, uniform clamping can be achieved, ensuring the stability of the workpiece during the grinding process. The moving mechanism 7 uses the method of driving the lead screw 72 by the bidirectional motor 71 to achieve the fast and stable movement of the clamping mechanism 6 on the workbench 1. The forward and reverse rotation control of the bidirectional motor 71 is precise. With the transmission of the lead screw 72 and the ferrule 73, the moving speed can be adjusted within the range of 0 - 500 millimeters per minute according to actual needs. In the maintenance of thermal power plant equipment, it is necessary to frequently adjust the position of the workpiece for multi-site grinding. The moving mechanism 7 can respond quickly, greatly shortening the workpiece positioning time and improving the overall grinding efficiency.

[0049] Working principle: When in use, if it is necessary to adjust the position of the grinding mechanism 3 in the horizontal direction, start the second motor 41 outside the stabilizing plate 49. The output shaft of the second motor 41 rotates, driving the rotating shaft 42 fixedly connected thereto to rotate. Since the rotating shaft 42 passes through the stabilizing plate 49 and the gear 43 is fixedly connected to the outside of the rotating shaft 42, the gear 43 rotates together with the rotating shaft 42. The gear 43 meshes with the toothed plate 46, and the toothed plate 46 is located in the chute 45 fixed to the outside of the stabilizing plate 49 through the connecting rod 44. When the gear 43 rotates, it drives the toothed plate 46 to slide horizontally in the chute 45. One side of the moving block 48 is fixedly connected to the toothed plate 46 through a sliding rod, and the sliding rod slides in the moving groove 47 on the side wall of the chute 45. The other side of the moving block 48 is fixed to the outside of the electric telescopic rod 31. Therefore, the sliding of the toothed plate 46 drives the moving block 48 to move, and then drives the electric telescopic rod 31 and the entire grinding mechanism 3 to move precisely in the horizontal direction to meet the grinding requirements at different positions. During the grinding process, the cleaning mechanism 5 automatically works to clean the generated dust. As the components in the adjusting mechanism 4 move, the connecting rod 51 follows the movement, and the first triangular block 52 fixed to the outside of the connecting rod 51 also moves. When the first triangular block 52 moves, it squeezes the second triangular block 58 that is in the same plane and in close contact with it. The second triangular block 58 is fixed to the top of the extrusion rod 57, and the extrusion rod 57 is installed inside the rotating block 56. The rotating block 56 is fixedly connected to the limiting rod 54, and the limiting rod 54 slides in the lifting groove 53 on the inner wall of the stabilizing plate 49. A return spring 55 is also connected to its bottom. The extrusion of the first triangular block 52 causes the rotating block 56 and the limiting rod 54 to move downward, compressing the return spring 55. At the same time, the downward movement of the rotating block 56 drives the extrusion rod 57 to squeeze the elastic airbag box 59 downward. After the elastic airbag box 59 is squeezed, the gas inside it is blown out through the air outlet plate 510 connected to the outside. The air outlet plate 510 is located on the top of the workbench 1, and the blown gas blows the dust generated by grinding on the top of the workbench 1 away, keeping the working environment clean. When the first triangular block 52 leaves the second triangular block 58, the return spring 55 resets, driving the limiting rod 54 and the rotating block 56 to rise, and the extrusion rod 57 no longer squeezes the elastic airbag box 59, completing a cleaning cycle. After placing the workpiece on the workbench 1, it needs to be clamped and fixed. Start the hydraulic cylinder 63 in the installation frame 62. The hydraulic cylinder 63 works to push the piston rod 64 to extend. A pushing disc 66 is fixed to the outside of the piston rod 64. As the piston rod 64 extends, the pushing disc 66 moves forward. Rotating rods 65 are symmetrically distributed on the outside of the installation frame 62. A transmission rod 67 is rotatably connected inside the rotating rod 65. A clamping plate 68 is fixed to the outside of the transmission rod 67, and the connection between the transmission rod 67 and the clamping plate 68 is located inside the pushing disc 66. When the pushing disc 66 moves, it drives the rotating rod 65 to rotate around its connection point with the installation frame 62. The rotating rod 65 drives the transmission rod 67 to rotate, and the transmission rod 67 further drives the clamping plate 68 to move towards the workpiece until the clamping plates 68 on both sides firmly clamp the workpiece, ensuring that the position of the workpiece is fixed during the grinding process.To ensure the grinding accuracy, if it is necessary to adjust the position of the clamping mechanism 6 on the workbench 1, start the bidirectional motor 71 inside the workbench 1. The output ends of the bidirectional motor 71 are in opposite directions. The rotation of its output shaft drives the rotation of the lead screw 72 fixedly connected thereto. A collar 73 is threadedly connected to the outside of the lead screw 72. The top of the collar 73 is fixedly connected to an extension rod 74. The extension rod 74 slides in a conduction groove 75 opened inside the workbench 1, and the top of the extension rod 74 is fixedly connected to the bottom of the fixing plate 61. When the bidirectional motor 71 rotates, the rotation of the lead screw 72 causes the collar 73 to move axially on the lead screw 72. The collar 73 drives the extension rod 74 to move in the conduction groove 75, thereby driving the fixing plate 61 and the entire clamping mechanism 6 to move horizontally on the workbench 1, facilitating the adjustment of the position of the clamping mechanism 6 to meet the grinding requirements of workpieces at different positions.,
