Description

Technical Field

[0001] The present application relates to the technical field of power equipment maintenance, and in particular to a carbon brush grinder for a large steam turbine generator. Background Art

[0002] In the complex operating system of large steam turbine generators, carbon brushes play an important role. They are not only a bridge for the transmission of rotor excitation current, but also one of the key factors to ensure the efficient and stable operation of the generator. The contact between the carbon brush and the collector ring is directly related to the efficiency and stability of current transmission, which in turn affects the performance of the entire power generation system. The traditional method of grinding carbon brushes relies on manual operation. The limitations of this method are obvious: first, the efficiency of manual grinding is extremely limited and it is difficult to meet the needs of modern industry for efficient production; second, the subjectivity and inconsistency of manual operation make it difficult for the contact area and quality of the ground carbon brush surface and the collector ring to meet unified and high standards. Usually, the design specifications require that the contact area must reach more than 85% to ensure good current transmission and mechanical contact performance.

[0003] Insufficient contact area or uneven grinding quality will directly lead to increased resistance during current transmission and generate additional heat, which will not only reduce the efficiency of the generator, but also accelerate the wear of carbon brushes and collector rings, shortening their service life. More seriously, poor contact may cause electrical failures, such as sparking and arcing, which may threaten the stable operation of the generator and even in some extreme cases, may cause the generator to shut down, affecting the stability and safety of the entire power supply system.

[0004] Although some special mechanical grinding technologies have been developed in recent years to try to solve the various shortcomings of manual grinding, these technologies still face many challenges in practical applications. For example, in terms of grinding accuracy, mechanical grinding equipment requires a more sophisticated control mechanism to ensure that each grinding can achieve the ideal contact area and surface finish; in terms of convenience, how to make mechanical grinding equipment easier to operate and maintain, and adapt to carbon brushes of different models and specifications is also an urgent problem to be solved in the current technological development.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limitations on the present application. On the contrary, the embodiments of the present application include all changes, modifications and equivalents that fall within the spirit and connotation of the appended claims.

[0029] The large steam turbine generator carbon brush grinder according to an embodiment of the present application is described below in conjunction with the accompanying drawings.

[0031] It is understandable that the frame 1 is the supporting structure of the entire grinding machine, and is used to fix and support all other components. It is usually made of strong and durable materials to ensure the stability and durability of the entire grinding machine.

[0032] The grinding roller 2 is a key component rotatably arranged on the frame 1, and achieves the grinding effect through contact and friction with the carbon brush. The surface of the grinding roller 2 is usually made of wear-resistant material to ensure that good grinding performance can be maintained during long-term use.

[0033] The transmission device 3 may include a transmission assembly 31 , wherein the transmission assembly 31 is disposed on one side of the frame 1 , and the transmission assembly 31 is connected to the grinding roller 2 .

[0034] It can be understood that the transmission device 3 is used to drive the grinding roller 2 to rotate. It mainly includes a transmission assembly 31, which is arranged on one side of the frame 1 and connected to the grinding roller 2. The transmission assembly 31 is also composed of a motor, a reducer and other components. The power provided by the motor is decelerated by the reducer and then transmitted to the grinding roller 2, so that it rotates at an appropriate speed.

[0035] The adjusting device 4 may include a first adjusting component 41 and a second adjusting component 42 , wherein the first adjusting component 41 is slidably disposed on one side of the frame 1 , and the second adjusting component 42 is rotatably disposed on the first adjusting component 41 .

[0036] It can be understood that the adjusting device 4 is used to adjust the position and angle of the brush box 5 to adapt to carbon brushes of different sizes and shapes. It mainly includes a first adjusting component 41 and a second adjusting component 42. The first adjusting component 41 is slidably arranged on one side of the frame 1, and is used to adjust the position of the brush box 5 in the horizontal direction. The second adjusting component 42 is rotatably arranged on the first adjusting component 41, and is used to adjust the inclination angle of the brush box 5. This design enables the grinder to flexibly adapt to the needs of various carbon brushes.

[0037] The brush box 5 is arranged on the top of the second adjustment component 42 .

[0038] It is understandable that the brush box 5 is arranged on the top of the second adjustment assembly 42 to accommodate and fix the carbon brush to be ground. The design of the brush box 5 should facilitate the placement and removal of the carbon brush and maintain the stability and position accuracy of the carbon brush during the grinding process.

[0039] The control device 6 may include a control component 61 , wherein the control component 61 is disposed on one side of the frame 1 , and the control component 61 is electrically connected to the transmission component 31 .

[0040] It is understood that the control device 6 is used to control the operation of the entire grinding machine. It mainly includes a control component 61, which is arranged on one side of the frame 1 and is electrically connected to the transmission component 31. Through the control component 61, the user can easily start, stop and adjust the operating parameters of the grinding machine, such as the rotation speed of the grinding roller 2, the grinding time, etc. In addition, the control device 6 may also include other auxiliary functions, such as fault alarm, safety protection, etc.

[0041] In one embodiment of the present application, Figure 2 and Figure 3 As shown, the transmission assembly 31 may include a side plate 311, a bearing seat 312 and a connecting shaft 313, wherein the side plate 311 is arranged on one side of the frame 1, the bearing seat 312 is arranged on the top of the side plate 311, the connecting shaft 313 is rotatably arranged in the bearing seat 312, and one end of the connecting shaft 313 is connected to the grinding roller 2, and the other end is connected to the external variable frequency motor.

[0042] It is understandable that the side plate 311 is a supporting structure of the transmission assembly 31, which is arranged on one side of the frame 1 to fix and support other components. The side plate 311 is usually made of a strong and durable material to ensure the stability and durability of the entire transmission assembly 31.

[0043] The bearing seat 312 is arranged on the top of the side plate 311 and is a supporting component of the connecting shaft 313. A bearing is arranged inside the bearing seat 312 to support the rotation of the connecting shaft 313 and reduce friction and wear during the rotation process. The design of the bearing seat 312 should ensure that the connecting shaft 313 can rotate steadily and smoothly, and can withstand certain radial and axial loads.

[0044] The connecting shaft 313 is the core component of the transmission assembly 31, and is rotatably disposed in the bearing seat 312. One end of the connecting shaft 313 is connected to the grinding roller 2, and drives the grinding roller 2 to rotate by transmitting torque. The other end of the connecting shaft 313 is connected to an external variable frequency motor, and the power provided by the variable frequency motor drives the connecting shaft 313 to rotate. The use of the variable frequency motor enables the grinding machine to adjust the rotation speed of the grinding roller 2 as needed, thereby achieving a more refined grinding effect.

[0045] At one end of the connecting shaft 313 connected to the grinding roller 2, a key connection is usually used to ensure reliable and stable torque transmission between the connecting shaft 313 and the grinding roller 2. At the same time, the connection between the connecting shaft 313 and the variable frequency motor is also usually connected by a coupling or a pulley or other transmission components to ensure smooth power transmission.

[0046] In summary, the transmission assembly 31 realizes the function of transmitting the power provided by the external variable frequency motor to the grinding roller 2, thereby driving the grinding roller 2 to rotate, through the coordinated work of the three key components of the side plate 311, the bearing seat 312 and the connecting shaft 313. This design enables the grinding machine to adjust the speed and grinding effect of the grinding roller 2 as needed to meet different grinding requirements.

[0047] In one embodiment of the present application, Figure 4As shown, the first adjustment component 41 may include a mounting frame 411, two slide rails 412, a sliding plate 413 and two first adjustment holes 414, wherein the mounting frame 411 is arranged at the upper end of one side of the frame 1, the two slide rails 412 are arranged at both ends of the mounting frame 411, the sliding plate 413 can be slidably arranged on the two slide rails 412, and the two groups of first adjustment holes 414 are respectively arranged at both ends of the sliding plate 413, and the two groups of first adjustment holes 414 are respectively movably connected to the two slide rails 412.

[0048] It can be understood that the mounting bracket 411 is a fixed component of the first adjustment assembly 41 , and is disposed at an upper end of one side of the frame 1 .

[0049] The slide rails 412 are two parallel rails, which are respectively arranged at two ends of the mounting frame 411. The slide rails 412 provide a stable and smooth sliding track for the sliding plate 413, so that the sliding plate 413 can move freely in the horizontal direction.

[0050] The sliding plate 413 is a movable component of the first adjusting assembly 41 , and is slidably disposed on the two sliding rails 412 .

[0051] Two groups of first adjustment holes 414 are respectively arranged at both ends of the sliding plate 413, and each group of first adjustment holes 414 is movably connected to a slide rail 412. The design of the first adjustment holes 414 should be convenient for fixing the sliding plate 413 at different positions on the slide rail 412 by fasteners (such as bolts, nuts, etc.), so as to achieve precise adjustment of the brush box 5 in the horizontal direction. By adjusting the relative position between the first adjustment holes 414 and the slide rail 412, the horizontal position of the sliding plate 413 and the brush box 5 can be conveniently changed to adapt to carbon brushes of different sizes.

[0052] In summary, the first adjustment assembly 41 realizes precise adjustment of the brush box 5 in the horizontal direction through the coordinated work of the mounting frame 411, the slide rail 412, the slide plate 413 and the first adjustment hole 414. This design enables the grinder to flexibly adapt to carbon brushes of different sizes, thereby improving grinding efficiency and precision.

[0054] It can be understood that the rotating seat 421 is a core component of the second adjusting assembly 42 , and it is rotatably disposed on the top of the sliding plate 413 .

[0055] Two groups of second adjustment holes 422 are respectively arranged on the side walls at both ends of the sliding plate 413, and each group of second adjustment holes 422 is movably connected to the rotating seat 421. The design of the second adjustment holes 422 should be convenient for fixing the rotating seat 421 at different positions on the sliding plate 413 by fasteners (such as bolts, nuts, etc.), thereby changing the inclination angle of the rotating seat 421 and the brush box 5. By adjusting the relative position between the second adjustment holes 422 and the rotating seat 421, the inclination angle of the brush box 5 can be conveniently changed to meet different grinding requirements.

[0056] In actual operation, the user can loosen the fasteners to allow the rotating seat 421 to rotate freely on the sliding plate 413. Then, by rotating the rotating seat 421 to a desired tilt angle and fixing the rotating seat 421 in the corresponding second adjustment hole 422 on the sliding plate 413 using fasteners, the tilt angle of the brush box 5 is adjusted.

[0057] In summary, the second adjustment component 42 realizes precise adjustment of the inclination angle of the brush box 5 through the coordinated work of the rotating seat 421 and the two sets of second adjustment holes 422. This design enables the grinder to flexibly adapt to different grinding requirements and improves grinding efficiency and accuracy. At the same time, the second adjustment component 42 has a simple structure and is easy to operate, providing users with a more convenient and efficient grinding experience.

[0058] In one embodiment of the present application, Figure 1 As shown, the control component 61 may include a control panel 611 and a switch key 612, wherein the control panel 611 is arranged on a side wall of the frame 1, and the control panel 611 is electrically connected to the external variable frequency motor, and the switch key 612 is arranged on one side of the control panel 611, and the switch key 612 is electrically connected to the control panel 611.

The control panel 611 is electrically connected to the external variable frequency motor, and realizes precise control of the working state of the grinder by controlling the operating parameters of the variable frequency motor (such as speed, rotation direction, power, etc.).

[0060] The switch key 612 is an important component in the control assembly 61 for controlling the start and stop of the grinder. It is arranged on one side of the control panel 611, so that the user can operate it quickly. The switch key 612 is usually designed in the form of a button or a switch. The user only needs to press or turn the switch key 612 to start or stop the grinder. At the same time, the switch key 612 is electrically connected to the control panel 611, and the on-off control of the grinder power circuit is realized through the circuit and logic control inside the control panel 611.
