Description

Technical Field

[0001] This utility model relates to the technical field of portable hydro-generator brake repair devices, and in particular to a portable hydro-generator brake repair device. Background Technology

[0002] The brake in a hydro-generator unit, as a key component ensuring safe and normal shutdown of the unit and realizing rotor load reduction and braking functions, plays a vital role in the stable operation of the unit. During unit shutdown, when the speed drops to a specific proportion of the rated speed, the brake needs to continuously brake the rotating parts of the unit to prevent the thrust bearing from burning out due to the inability to build up an oil film caused by prolonged low-speed operation. In some cases, the unit also needs to be locked to prevent it from rotating on its own. In addition, before restarting the unit after maintenance or a long-term shutdown, the rotor needs to be pushed up to lubricate the bearing surfaces with oil. During routine maintenance of the generator unit, the brake is moved by rollers and manual handling, which not only easily damages the surface of other equipment, but also poses a great safety hazard due to the heavy weight of a single brake. At the same time, the overall maintenance efficiency is low. Based on this, a portable hydro-generator brake maintenance device is proposed to solve the above problems. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a portable hydro-generator brake maintenance device, which solves the problem that during routine maintenance of the unit, moving the brake by rollers and manual handling not only easily damages the surface of other equipment, but also poses a great safety hazard due to the heavy weight of a single brake, and results in low overall maintenance efficiency.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a portable water turbine generator brake maintenance device, comprising a receiving base plate, an electrical control box fixedly installed at the top front section of the receiving base plate, a fixed frame fixedly connected to the top middle section of the receiving base plate, a drive motor fixedly installed on the outer wall of the fixed frame, a bidirectional lead screw fixedly connected to the inner output end of the drive motor, a sliding frame threadedly connected to the outer wall of the bidirectional lead screw, a cylinder fixedly installed at the bottom of the inner wall of the middle section of the sliding frame, a pneumatic push rod fixedly connected to the top output end of the cylinder, a fixed block fixedly connected to the top of the pneumatic push rod, hinge blocks hinged to the outer walls on both sides of the fixed block, a clamp hinged to the inner side of the hinge block, a limit slide rail fixedly connected to the top of the sliding frame, a receiving rod fixedly connected to the top of the sliding frame, and a receiving support plate fixedly connected to the top of the receiving rod.

[0005] A further improvement is that the front and rear sections of the top of the receiving substrate are fixedly connected to fixed slide rails; the limiting slide groove at the bottom of the sliding frame is slidably connected to the outer wall of the fixed slide rail, and the fixed slide rail is fixedly connected to the front and rear sections of the top of the receiving substrate, which makes the sliding frame stable during movement and prevents it from shifting.

[0006] A further improvement is that an anti-sliding block is fixedly connected to the top of the receiving plate, and the anti-sliding blocks are equidistantly arranged on the top of the receiving plate; as the sliding frame moves, the receiving rod fixedly connected to its top and the receiving plate on the top of the receiving rod will also move accordingly; the sliding frame is symmetrically arranged on both sides of the top of the receiving base plate, and correspondingly, the receiving plate and the anti-sliding block are also symmetrically arranged on both sides of the top of the receiving base plate. The anti-sliding block is fixedly connected to the top of the receiving plate and is equidistantly arranged, which can effectively increase the friction with the brake and prevent the brake from sliding on the receiving plate.

[0007] A further improvement is that the fixing frame is symmetrically arranged on both sides of the top of the receiving base plate, and the bidirectional screw is rotatably connected to the inner wall of the fixing frame; the fixing frame is symmetrically arranged on both sides of the top of the receiving base plate to provide stable support for the drive motor; the bidirectional screw fixedly connected to the inner output end of the drive motor starts to rotate, and since the bidirectional screw is rotatably connected to the inner wall of the fixing frame, when it rotates, the sliding frame connected to the outer wall thread will move along the axial direction of the bidirectional screw under the action of the thread.

[0008] A further improvement is that the limiting groove at the bottom of the sliding frame is slidably connected to the outer wall of the fixed slide rail, and the bottom of the sliding frame is slidably connected to the top outer wall of the receiving base plate; when the receiving plate moves to a suitable position and is located below the brake of the water turbine generator, the cylinder is activated. The cylinder is fixedly installed at the bottom of the inner wall of the middle section of the sliding frame, and the pneumatic push rod fixedly connected to its top output end will extend upward; the fixed block fixedly connected to the top of the pneumatic push rod will rise accordingly, and the hinge blocks hinged to the outer walls on both sides of the fixed block will also be driven to rise.

[0009] A further improvement is that the clamp is slidably connected to the top outer wall of the limiting slide rail, and the clamp is symmetrically arranged on the front and rear outer walls of the sliding frame; since the clamp is hinged to the inner side of the hinge block, and the clamp is slidably connected to the top outer wall of the limiting slide rail, and the limiting slide rail is fixedly connected to the top of the sliding frame, as the hinge block rises, the clamp will slide along a specific direction on the limiting slide rail, thereby clamping and fixing the turbine generator brake.

[0010] A further improvement is that the sliding frame is symmetrically arranged on both sides of the top of the receiving base plate, and the receiving plate and the anti-slip block are symmetrically arranged on both sides of the top of the receiving base plate. During subsequent maintenance operations on the brake, all components of the device continuously work together to maintain a stable state. The electrical control box can precisely adjust the operating parameters of components such as the drive motor and cylinder according to actual needs, ensuring that the entire maintenance process is safe and efficient. For example, when it is necessary to adjust the position of the brake, the drive motor is restarted, and the sliding frame is moved through the bidirectional lead screw, thereby moving the clamped brake to a suitable position, which facilitates maintenance personnel to carry out various maintenance tasks.

[0011] By employing the above technical solution, this utility model provides a portable hydro-generator brake maintenance device, which has at least the following beneficial effects: 1. This utility model, through the coordinated action of a drive motor, a bidirectional lead screw, and a sliding frame, can precisely move the receiving plate to below the brake, replacing the traditional method of manual handling or reliance on large lifting equipment. This effectively solves the problems of heavy brakes and difficult handling, significantly reducing labor costs and safety hazards. The cylinder-driven clamp can quickly clamp the brake, and with the anti-slip effect of the anti-slip block, it ensures the brake is stably fixed during maintenance, avoiding equipment damage or personnel injury caused by shaking. Moreover, maintenance can be carried out without waiting for components such as the generator rotor to be lifted out, significantly shortening the maintenance cycle and improving overall maintenance efficiency. 2. This utility model device is based on a base plate, with each component arranged in a reasonable and closely coordinated manner. The electrical control box can precisely control the operation of the drive motor and cylinder, enabling flexible adjustment of the brake position to meet the position requirements of different maintenance scenarios. The design of the sliding frame sliding along the fixed slide rail and the clamping frame sliding along the limit slide rail ensures the stability and accuracy of the movement and clamping process, making it suitable for maintenance work of different specifications of hydro-generator brakes. The device has a compact overall structure, making it easy to carry to different maintenance sites, breaking through the limitations of traditional maintenance methods on site and equipment, and improving the convenience and applicability of operation.

[0016] During routine maintenance of the generator unit, moving the brakes using rollers and manual handling is not only prone to damaging other equipment surfaces, but also poses significant safety hazards due to the heavy weight of individual brakes, resulting in low overall maintenance efficiency. This embodiment provides a portable hydro-generator brake maintenance device. Please refer to... Figures 1-4This embodiment provides a portable hydro-generator brake maintenance device, including a receiving base plate 1.

A sliding frame 7 is threadedly connected to the outer wall of the bidirectional lead screw 5. A cylinder 8 is fixedly mounted on the bottom inner wall of the middle section of the sliding frame 7. A pneumatic push rod 9 is fixedly connected to the top output end of the cylinder 8. A fixing block 10 is fixedly connected to the top of the pneumatic push rod 9. Hinge blocks 11 are hinged to the outer walls on both sides of the fixing block 10. A clamp 12 is hinged to the inner side of the hinge block 11. A limit rail 13 is fixedly connected to the top of the sliding frame 7. A receiving rod 14 is fixedly connected to the top of the sliding frame 7. A receiving rod 14 is fixedly connected to a receiving plate 15 at its top; a fixed slide rail 6 is fixedly connected to the front and rear sections of the top of the receiving base plate 1; an anti-sliding block 16 is fixedly connected to the top of the receiving plate 15, and the anti-sliding blocks 16 are equidistantly arranged on the top of the receiving plate 15; a fixed frame 3 is symmetrically arranged on both sides of the top of the receiving base plate 1, and a bidirectional screw 5 is rotatably connected to the inner wall of the fixed frame 3; a limiting groove opened at the bottom of the sliding frame 7 is slidably connected to the outer wall of the fixed slide rail 6, and the bottom of the sliding frame 7 is slidably connected to the outer wall of the top of the receiving base plate 1; a clamp 12 is slidably connected to the outer wall of the top of the limiting slide rail 13, and the clamp 12 is symmetrically arranged on the outer walls of the front and rear sections of the sliding frame 7; the sliding frame 7 is symmetrically arranged on both sides of the top of the receiving base plate 1, and the receiving plate 15 and the anti-sliding block 16 are symmetrically arranged on both sides of the top of the receiving base plate 1.

[0017] Working principle: When the brake of the hydro-generator needs to be inspected, the drive motor 4 is started. The drive motor 4 is fixedly installed on the outer wall of the fixed frame 3, which is symmetrically arranged on both sides of the top of the receiving base plate 1 to provide stable support for the drive motor 4. The bidirectional lead screw 5, which is fixedly connected to the inner output end of the drive motor 4, starts to rotate. Since the bidirectional lead screw 5 is rotatably connected to the inner wall of the fixed frame 3, when it rotates, the sliding frame 7, which is threaded on the outer wall, will move along the axial direction of the bidirectional lead screw 5 under the action of the thread. Furthermore, since the limiting groove opened at the bottom of the sliding frame 7 is slidably connected to the outer wall of the fixed slide rail 6, and the fixed slide rail 6 is fixedly connected to the front and rear sections of the top of the receiving base plate 1, the sliding frame 7 can remain stable during movement and will not deviate. As the sliding frame 7 moves, the receiving rod 14 fixedly connected to its top and the receiving plate 15 on top of the receiving rod 14 also move accordingly. The sliding frame 7 is symmetrically arranged on both sides of the top of the receiving base plate 1. Correspondingly, the receiving plate 15 and the anti-slip block 16 are also symmetrically arranged on both sides of the top of the receiving base plate 1. The anti-slip block 16 is fixedly connected to the top of the receiving plate 15 and is equidistant, which can effectively increase the friction with the brake and prevent the brake from sliding on the receiving plate 15. When the receiving plate 15 moves to a suitable position and is located below the turbine generator brake, the cylinder 8 is activated. The pneumatic push rod 9, which is fixedly installed at the bottom of the inner wall of the middle section of the sliding frame 7 and is fixedly connected to the top output end, will extend upward; the fixed block 10, which is fixedly connected to the top of the pneumatic push rod 9, will rise accordingly, and the hinge blocks 11, which are hinged to the outer walls on both sides of the fixed block 10, will also be driven to rise; since the inner side of the hinge block 11 is hinged to the clamp 12, and the clamp 12 is slidably connected to the top outer wall of the limit slide rail 13, and the limit slide rail 13 is fixedly connected to the top of the sliding frame 7, as the hinge block 11 rises, the clamp 12 will slide along the limit slide rail 13 in a specific direction, thereby clamping and fixing the water turbine generator brake; During subsequent maintenance of the brake, all components of the device work together to maintain a stable state. The electrical control box 2 can precisely control the operating parameters of components such as the drive motor 4 and cylinder 8 according to actual needs, ensuring that the entire maintenance process is carried out safely and efficiently. For example, when it is necessary to adjust the position of the brake, the drive motor 4 is restarted, and the sliding frame 7 is moved through the bidirectional lead screw 5, thereby moving the clamped brake to a suitable position, which facilitates maintenance personnel to carry out various maintenance tasks.
