Description

Technical Field

[0001] This utility model belongs to the field of water turbine maintenance equipment, and specifically relates to an adjustable electric disc brush holder. Background Technology

[0002] In the power and machinery industries, electric turning gear brush holders, as crucial power transmission components, are widely used in various motor equipment. Their performance directly impacts the operational stability and reliability of the equipment. Traditional electric turning gear brush holders have relatively fixed structures, typically employing a one-piece design. The position and angle of the brush holder are difficult to adjust flexibly to accommodate rotors of different specifications. When dealing with rotors of varying sizes and models, traditional brush holders often fail to guarantee good contact between the carbon brushes and the rotor, easily leading to poor contact, unstable power transmission, and ultimately, reduced equipment operating efficiency or even malfunctions. Furthermore, traditional brush holders have significant limitations in maintenance and repair. Due to their compact and non-removable structure, when carbon brushes wear out and need replacement, or when the brush holder requires maintenance, the entire brush holder often needs to be disassembled. This process is cumbersome, consumes a lot of time and labor, and also increases equipment downtime, affecting production efficiency. Moreover, traditional brush holders lack precise positioning and a stable moving structure during movement and adjustment. During equipment operation, factors such as vibration can easily cause the brush holder to shift position, further affecting the normal operation of the equipment. Therefore, in order to solve the above-mentioned problems of existing electric rotary brush holders, it is urgent to develop an adjustable electric rotary brush holder that can be flexibly adjusted, accurately positioned, easy to maintain, and stable in operation, so as to meet the needs of equipment operation under different working conditions and improve the overall performance and reliability of the equipment. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide an adjustable electric rotating brush holder, which can quickly adjust the position of the carbon brush holder regardless of the size or model of the rotor, ensuring that the carbon brush and the rotor always maintain good contact, and effectively avoiding the poor contact problem caused by the fixed structure of traditional brush holders.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: An adjustable electric rotating brush holder includes an outer frame, on which a movable frame is slidably mounted. There are at least two movable frames arranged opposite each other. An arc-shaped plate is mounted on the movable frame, and a carbon brush holder is mounted on the arc-shaped plate. A space is left between the two movable frames for the rotor to rotate. Preferably, the bottom of the outer frame is provided with a lower rail, which is adapted to the lower moving wheel, and the lower moving wheel is installed at the bottom of the moving frame.

[0005] Preferably, the bottom of the outer frame is provided with a first positioning plate, which has multiple positioning holes arranged linearly; the first positioning plate is adapted to a second positioning plate, which has positioning holes, and the second positioning plate is installed on the movable frame, and the second positioning plate and the first positioning plate are fixed together by positioning bolts.

[0006] Preferably, each movable frame is provided with two second positioning hole plates at the bottom, and each second positioning hole plate is provided with a corresponding first positioning hole plate. The first positioning hole plate is installed next to the lower rail, and the arrangement direction of the multiple positioning holes on the first positioning hole plate is consistent with the installation direction of the lower rail.

[0007] Preferably, the bottom of the movable frame is provided with a support slider, which is adapted to the slide groove, and the slide groove is installed at the bottom of the outer frame.

[0008] Preferably, the top of the outer frame is provided with an upper rail, which is adapted to the upper moving wheel, and the upper moving wheel is installed on the top of the mobile frame.

[0009] Preferably, the movable frame is driven to move by a movable frame position adjustment device, which includes a servo motor and is connected to the movable frame through a lead screw adjustment mechanism.

[0010] Preferably, the arc-shaped plate includes an upper arc-shaped plate and a lower arc-shaped plate, the upper arc-shaped plate being detachably mounted on the top of the carbon brush holder, and the lower arc-shaped plate being fixedly connected to the movable frame.

[0011] Preferably, the upper arc-shaped plate and the lower arc-shaped plate are connected by multiple support rods.

[0012] Preferably, the carbon brush holder is a frame structure composed of multiple perforated plates.

[0013] The present invention can achieve the following beneficial effects: 1. This utility model features a sliding movable frame driven by a servo motor and a lead screw adjustment mechanism, enabling precise and flexible position adjustment for rotors of different specifications. Regardless of rotor size or model, the position of the carbon brush holder can be quickly adjusted to ensure consistent and good contact between the carbon brushes and the rotor. This effectively avoids the poor contact problems caused by the fixed structure of traditional brush holders, greatly improving the equipment's adaptability to different working conditions and enhancing its operating efficiency. 2. The cooperation between the first positioning plate, the second positioning plate, and the positioning bolts, as well as the structural design of the upper and lower rails, the moving wheels, the support slider, and the slide groove, together provide a stable and precise positioning method for the moving frame. After the moving frame is adjusted to the appropriate position, it can be firmly fixed. Even if the equipment is subjected to vibration or external force during operation, it will not shift, ensuring the stability of the relative position between the carbon brush holder and the rotor. This makes power transmission more stable and reliable, reducing the risk of failure caused by positional deviation. 3. The arc-shaped plate adopts a detachable upper and lower arc-shaped plate structure. When the carbon brushes wear out and need replacement, or when the carbon brush holder needs maintenance, only the upper arc-shaped plate needs to be removed for easy access to the carbon brush holder, without disassembling the entire brush holder. This greatly simplifies the maintenance process, saves maintenance time and labor costs, effectively shortens equipment downtime, and improves production efficiency. At the same time, the carbon brush holder uses a frame structure spliced ​​with multiple perforated plates, which not only facilitates the installation and removal of carbon brushes but also promotes air circulation, reduces carbon brush operating temperature, extends carbon brush life, and further enhances the maintainability of the equipment. 4. The symmetrically arranged tracks and wheels, as well as the supporting sliders and grooves, enhance the stability of the moving frame during movement, better withstand various forces generated during operation, and reduce tilting or jamming caused by uneven force.

[0015] In the figure: outer frame 1, movable frame 2, arc plate 3, carbon brush holder 4, lower rail 5, lower moving wheel 6, first positioning hole plate 7, second positioning hole plate 8, support slider 9, slide groove 10, upper rail 11, upper moving wheel 12, movable frame position adjustment device 13, support rod 14. Detailed Implementation

[0016] Preferred solutions include Figures 1 to 4As shown, an adjustable electric rotating brush holder includes an outer frame 1, on which a movable frame 2 is slidably mounted. There are at least two movable frames 2, arranged opposite each other. An arc-shaped plate 3 is mounted on each movable frame 2, and a carbon brush holder 4 is mounted on the arc-shaped plate 3. Space is left between the two movable frames 2 for rotor rotation. The outer frame serves as a fixed base, while the slidable movable frames are positioned according to actual needs. The cooperation between the arc-shaped plate and the carbon brush holder ensures stable contact between the carbon brush and the rotor. Furthermore, the bottom of the outer frame 1 is provided with a lower rail 5, which is adapted to the lower moving wheel 6, which is installed at the bottom of the moving frame 2. The cooperation between the lower rail 5 and the lower moving wheel 6 provides a stable sliding track for the moving frame, enabling it to move smoothly along a fixed direction during movement, reducing swaying and offset during movement, improving the accuracy and stability of the moving frame's position adjustment, and also reducing friction during movement, making the movement smoother. Furthermore, the bottom of the outer frame 1 is provided with a first positioning plate 7, which has multiple positioning holes arranged linearly. The first positioning plate 7 is adapted to a second positioning plate 8, which also has positioning holes. The second positioning plate 8 is mounted on the movable frame 2, and the second positioning plate 8 and the first positioning plate 7 are fixed together by positioning bolts. The positioning plates provide a precise positioning method for the movable frame. When the movable frame moves to the appropriate position, the positioning bolts pass through the corresponding positioning holes on the first and second positioning plates to firmly fix the movable frame to the outer frame, preventing displacement of the movable frame during equipment operation and ensuring the relative position stability between the carbon brush holder and the rotor. Furthermore, each movable frame 2 has two second positioning hole plates 8 at its bottom, and each second positioning hole plate 8 corresponds to a first positioning hole plate 7. The first positioning hole plate 7 is installed next to the lower rail 5, and the multiple positioning holes on the first positioning hole plate 7 are arranged in the same direction as the installation direction of the lower rail 5. This further enhances the accuracy and stability of the movable frame positioning. The two second positioning hole plates cooperate with the corresponding first positioning hole plates to form a double positioning point structure, which can better restrict the movement of the movable frame in the horizontal direction. Even when the equipment is subjected to large vibrations or external forces, the position of the movable frame can be kept fixed, thereby improving the reliability and stability of the entire brush frame system. Furthermore, the bottom of the movable frame 2 is provided with a support slider 9, which is adapted to the slide groove 10, which is installed at the bottom of the outer frame 1. The combination of the support slider and the slide groove provides additional support and guidance for the movable frame. The support slider can evenly distribute the weight of the movable frame and its components, reduce the force on the lower moving wheels, and extend their service life; at the same time, the cooperation between the slide groove and the support slider further limits the vertical sway of the movable frame, making the movable frame more stable during movement and improving the safety and stability of equipment operation. Furthermore, an upper rail 11 is provided at the top of the outer frame 1, which is adapted to the upper moving wheel 12, which is installed on the top of the mobile frame 2. The arrangement of the upper rail and the upper moving wheel, together with the lower rail and the lower moving wheel at the bottom, forms a symmetrical structure. This symmetrical design not only increases the stability of the mobile frame's movement, making the mobile frame more stable when adjusting its position, but also reduces tilting or jamming caused by uneven force, further improving the overall performance of the equipment. Furthermore, the movable frame 2 is driven to move by a movable frame position adjustment device, which includes a servo motor connected to the movable frame 2 via a lead screw adjustment mechanism. This combination of a servo motor and a lead screw adjustment mechanism enables precise automatic adjustment of the movable frame position. The servo motor offers high control precision, accurately controlling the rotation of the lead screw according to a preset program or external commands, thereby driving the movable frame to move precisely along the track. This adjustment method not only improves adjustment efficiency but also reduces errors caused by manual operation, making the position adjustment of the movable frame more accurate and reliable, meeting the precise requirements for the carbon brush holder position under different working conditions. Furthermore, the arc-shaped plate 3 includes an upper arc-shaped plate and a lower arc-shaped plate. The upper arc-shaped plate is detachably mounted on top of the carbon brush holder 4, and the lower arc-shaped plate is fixedly connected to the movable frame 2. This detachable structural design facilitates equipment maintenance and repair. When maintenance of the carbon brush holder or replacement of carbon brushes is required, the upper arc-shaped plate can be easily removed to directly contact the carbon brush holder without disassembling the entire arc-shaped plate and movable frame. This significantly shortens maintenance time, reduces maintenance costs, and also improves the maintainability and service life of the equipment. Furthermore, the upper and lower arc-shaped plates are connected by multiple support rods 14. The support rods enhance the connection strength and stability between the upper and lower arc-shaped plates. The evenly distributed support rods effectively disperse stress, prevent deformation or damage to the arc-shaped plates, and ensure the supporting effect of the arc-shaped plates on the carbon brush holder. This ensures that the carbon brushes can stably contact the rotor and guarantee the normal conduction of electricity. Furthermore, the carbon brush holder 4 is a frame structure composed of multiple perforated plates. This modular frame structure offers strong flexibility and scalability. By combining different perforated plates, the shape and size of the carbon brush holder can be adjusted according to actual needs to accommodate carbon brushes and rotors of different specifications. Simultaneously, the perforated plate structure facilitates the installation and removal of carbon brushes, promotes air circulation, reduces the temperature of the carbon brushes during operation, and improves their lifespan and performance, enabling the carbon brush holder to better meet the requirements of various operating conditions.
