Description

Technical Field

[0001] This utility model belongs to the field of power equipment technology, specifically a cylinder expansion observation device. Background Technology

[0002] In the operation of steam turbines in thermal power generation, nuclear power and other fields, the cylinder will undergo thermal expansion and contraction due to temperature changes. If the expansion is not monitored in a timely and accurate manner, it can easily lead to serious failures such as cylinder-rotor rubbing and seal failure.

[0003] In the existing technology, cylinder expansion observation has the following shortcomings: the manual visual inspection method relies on the inspection personnel to judge by simple markings or experience, which has low accuracy and strong subjectivity. It is easy to misjudge faults due to human negligence or visual errors. The sensor monitoring method partially uses displacement sensors, which have high accuracy, but have problems such as high cost, susceptibility to interference in high temperature environments, and complex installation and maintenance, making it difficult to be economically applicable on a large scale in industrial sites. The simple device method uses a simple ruler-pointer structure, which often lacks design for angle adjustment, cleaning and maintenance. After long-term use, it is easy to fail to observe due to dust cover and position displacement.

[0004] Therefore, there is an urgent need for an economical, practical, robust, reliable, and high-temperature resistant cylinder expansion observation device that can not only present expansion data intuitively, but also adapt to different cylinder structures and operating conditions to ensure the long-term stable operation of the unit. Utility Model Content

[0005] The purpose of this invention is to address the problem that existing simple ruler-pointer structures often lack angle adjustment and cleaning / maintenance features, leading to observation failures due to dust accumulation and positional shifts after long-term use. This invention proposes a cylinder expansion observation device to solve the problems mentioned in the background section.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The cylinder expansion observation device of this utility model includes a base plate, a telescopic frame fixedly connected to the top of the base plate, the telescopic frame being evenly distributed on the top of the base plate, a fixed slide rail fixedly connected to the top of the telescopic frame, a guide rail seat slidably fitted on the side wall of the fixed slide rail, a steel ruler plate added to the side of the fixed slide rail, a pointer installed at the corresponding position of the guide rail seat, an adjustment component rotatably fitted in the middle of the fixed slide rail, a cat's paw connector installed at the top of the guide rail seat, and a limit component set in the middle of the adjustment component. Through the above structure, the basic structure for cylinder expansion observation and the core observation function are realized. The pointer component of the cylinder cat's paw is connected to the guide rail seat and the cat's paw connector. Combined with the added steel ruler plate, the displacement observation of the pointer on the steel ruler plate is realized when the cylinder expands. At the same time, the telescopic frame and slide rail structure ensures the adaptability to different cylinders and the structural robustness.

[0007] Preferably, the adjustment component includes a rotating rod, and the side wall of the fixed slide rail is provided with rotating holes. The rotating holes are evenly distributed on the side wall of the fixed slide rail, and a rotating rod is rotatably fitted in the middle of each group of rotating holes. A movable slide rail is fixedly connected to the end of the rotating rod, and a rotating platform is installed on the top of the movable slide rail. The rotating platform is located between the movable slide rail and the cat claw connector. Through the above structure, the multi-dimensional angle adjustment function of the steel ruler plate is realized. Through the design of the rotating rod, rotating holes, movable slide rail, and rotating platform, the added steel ruler plate can be driven to rotate around the rotating holes and adjust its orientation, thereby adapting to the installation angle and position of different cylinder cat claws, making the correspondence between the pointer and the steel ruler plate more accurate.

[0008] Preferably, the limiting component includes limiting holes. The limiting holes are formed on the side walls of the rotating rod and the fixed slide rail frame. The limiting holes are evenly distributed on the side walls of the rotating rod. A limiting rod slides in the middle of the limiting holes. Through the above structure, the positioning and locking function of the steel ruler plate after adjustment is realized. Through the cooperation of the limiting holes and the limiting rod, the steel ruler plate with the adjusted angle can be firmly fixed to avoid external vibration causing its displacement. This ensures that the observation benchmark of the steel ruler plate-pointer is stable and the data reading is reliable during the cylinder expansion process.

[0009] Preferably, a fixing plate is fixedly connected to the side wall of the guide rail seat. The fixing plates are evenly distributed on the side wall of the guide rail seat. Each set of fixing plates is equipped with a cleaning brush on its side wall. The cleaning brushes are evenly distributed on the side wall of the fixing plates. Through the above structure, the cleaning function of the steel ruler plate observation area is realized. By cleaning the slide rail with the fixing plates and cleaning brushes, dust and debris are prevented from causing the guide rail seat to slide and jam, which indirectly ensures the smooth displacement of the pointer on the steel ruler plate and avoids the expansion data observation error caused by jamming.

[0010] Preferably, a placement frame is installed on the top of the base plate, and a control lever is slidably fitted in the middle of the placement frame. Two control levers are provided in the middle of the placement frame, and a cleaning plate is fixed to the side wall of each set of control levers. A collection assembly is provided in the middle of the base plate. Through the above structure, the cleaning and maintenance function of the surrounding environment of the steel ruler plate is realized. By cooperating with the control lever, the cleaning plate and the collection box, dust and debris on the base plate can be swept away, keeping the installation area of ​​the steel ruler plate clean, avoiding dust covering the scale or interfering with pointer observation, and improving the clarity of expansion data reading.

[0011] Preferably, a filling guide block is fixed to the top of the base plate and is positioned between the two cleaning plates. Through the above structure, the function of guiding and collecting debris in the steel ruler plate area is realized. The filling guide block can guide the cleaning plates to concentrate and sweep the debris towards the collection hole, thereby improving cleaning efficiency and further ensuring that there is no debris obstructing the area around the steel ruler plate and that the scale is always clearly visible.

[0012] Preferably, the collection component includes a collection box, a collection hole is provided in the middle of the base plate, and the collection box is fixed to the bottom of the base plate. The collection box and the collection hole are positioned correspondingly. Through the above structure, the function of centralized collection of debris in the steel ruler plate area is realized. The collection box and the collection hole work together to collect the cleaned debris, which is convenient for regular disassembly and cleaning, and maintains a clean environment in the steel ruler plate installation area for a long time, providing continuous protection for accurate observation of cylinder expansion.

[0013] The beneficial effects of this utility model are as follows: 1. The cylinder expansion observation device of this utility model realizes the basic structure and core observation function of cylinder expansion observation through the structural setting of the guide rail seat and the cat claw connector. The guide rail seat and the cat claw connector connect the pointer component of the cylinder cat claw. Combined with the added steel ruler plate, the displacement of the pointer on the steel ruler plate is observed when the cylinder expands. At the same time, the telescopic frame and the slide rail structure ensure the adaptability to different cylinders and the structural sturdiness.

[0014] 2. The cylinder expansion observation device described in this utility model, with its rotating rod, rotating hole, movable slide rail frame and rotating platform, realizes the multi-dimensional angle adjustment function of the steel ruler plate. It can drive the added steel ruler plate to rotate around the rotating hole and adjust its orientation, thereby adapting to the installation angle and position of different cylinder claws, making the correspondence between the pointer and the steel ruler plate more accurate.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Specific implementation examples are given below.

[0020] like Figures 1 to 2 As shown in the embodiment of this utility model, a cylinder expansion observation device includes a base plate 1. A telescopic frame 11 is fixedly connected to the top of the base plate 1. The telescopic frames 11 are evenly distributed on the top of the base plate 1. A fixed slide rail frame 12 is fixedly connected to the top of each telescopic frame 11. A guide rail seat 13 is slidably fitted to the side wall of the fixed slide rail frame 12. A steel ruler plate 15 is installed on the side of the fixed slide rail frame 12. A pointer 16 is installed at a corresponding position on the guide rail seat 13. An adjustment component is rotatably fitted in the middle of the fixed slide rail frame 12. A cat's paw connector 14 is installed at the top of the guide rail seat 13. A limit component is provided in the middle of the adjustment component. During operation, multiple evenly distributed telescopic frames 11 are fixedly connected to the top of the base plate 1 by bolts. A screw-type mechanical telescopic structure or a sleeve-type hydraulic / pneumatic telescopic structure is used, preferably a screw to ensure accuracy. The screw is manually or electrically driven to rotate, causing the inner and outer sleeves of the telescopic frame 11 to move relative to each other, thus achieving telescopic movement. The linkage drive shaft connects the lead screw drive ends of all telescopic frames 11 to ensure that each lead screw rotates synchronously, thereby ensuring that the telescopic amount of multiple telescopic frames 11 is completely consistent. This design can prevent the fixed slide rail frame 12 from tilting due to asynchronous telescopic extension and ensure the stability of the observation benchmark. The fixed slide rail frame 12 is welded to the top of the telescopic frame 11. The side wall of the fixed slide rail frame 12 slides in conjunction with the guide rail seat 13. The top of the fixed slide rail frame 12 is equipped with a cat claw connector 14 for connecting the pointer component of the cylinder cat claw. A steel ruler plate 15 is added to the side of the fixed slide rail frame 12, and a pointer 16 is installed at the corresponding position of the guide rail seat 13. When the cylinder expands, the cat claw drives the pointer 16 to move on the steel ruler plate 15. The expansion is observed intuitively by the scale change. This step can be achieved by the telescopic frame 11 being telescopic to adapt to different cylinder heights. The sliding fit between the fixed slide rail frame 12 and the guide rail seat 13, combined with the design of the steel ruler plate 15 and the pointer 16, realizes economical and intuitive observation of cylinder expansion. The structure is robust and highly adaptable.

[0021] like Figure 2As shown, the adjustment assembly includes a rotating rod 22. The side wall of the fixed slide rail frame 12 has rotating holes 21 evenly distributed. A rotating rod 22 is rotatably fitted in the middle of each group of rotating holes 21. A movable slide rail frame 2 is fixedly connected to the end of the rotating rod 22. A rotating platform 23 is mounted on the top of the movable slide rail frame 2. The rotating platform 23 is positioned between the movable slide rail frame 2 and the cat claw connector 14. During operation, multiple evenly distributed rotating holes 21 are formed on the side wall of the fixed slide rail frame 12. Rotating rod 22 is rotated within rotating hole 21. Movable slide rail 2 is welded to the end of rotating rod 22, and rotating platform 23 is installed on its top to connect cat claw connector 14. A steel ruler plate is added to the side of movable slide rail 2. Rotating rod 22 can drive movable slide rail 2 to rotate around rotating hole 21. Rotating platform 23 can adjust the orientation and angle of steel ruler plate. This step can be adjusted in multiple dimensions through rotating rod 22 and rotating platform 23. Steel ruler plate can be adapted to the installation angle and position of cat claw for different cylinders, improving observation flexibility and ensuring accurate correspondence between pointer and steel ruler plate.

[0022] like Figure 4 As shown, the limiting component includes limiting holes 3. The rotating rod 22 and the fixed slide rail frame 12 have limiting holes 3 on their side walls. The limiting holes 3 are evenly distributed on the side walls of the rotating rod 22. A limiting rod 31 slides in the middle of the limiting holes 3. During operation, multiple sets of evenly distributed limiting holes 3 are opened on the side walls of the rotating rod 22 and the fixed slide rail frame 12. After adjusting the angle of the movable slide rail frame 2 and the steel ruler plate, the limiting rod 31 is inserted into the corresponding limiting hole 3 to achieve the positioning of the rotating rod 22. This step allows the limiting component to firmly fix the adjustment position of the steel ruler plate, avoid external vibration causing it to shift, and ensure the stability and reliability of the expansion data reading.

[0023] like Figure 2 As shown, a fixing plate 4 is fixedly connected to the side wall of the guide rail seat 13. The fixing plates 4 are evenly distributed on the side wall of the guide rail seat 13. Each set of fixing plates 4 is equipped with a cleaning brush 41. The cleaning brushes 41 are evenly distributed on the side wall of the fixing plates 4. During operation, multiple sets of evenly distributed fixing plates 4 are welded to the side wall of the guide rail seat 13. Multiple sets of cleaning brushes 41 are installed on the side wall of each set of fixing plates 4 by screws. The cleaning brushes 41 are in contact with the slide rail surface of the fixed slide rail frame 12. In this step, when the guide rail seat 13 slides, the cleaning brushes 41 can clean the dust and debris on the slide rail, ensuring that the guide rail seat 13 slides smoothly, indirectly avoiding the pointer displacement and jamming on the steel ruler plate, and improving the observation accuracy of expansion data.

[0024] like Figure 3As shown, a placement frame 5 is installed on the top of the base plate 1. A control lever 51 is slidably fitted in the middle of the placement frame 5. Two control levers 51 are provided in the middle of the placement frame 5. A cleaning plate 52 is fixedly connected to the side wall of each set of control levers 51. A collection assembly is provided in the middle of the base plate 1. During operation, two control levers 51 are slidably fitted inside the placement frame 5. A cleaning plate 52 is welded to the side wall of each set of control levers 51. A collection hole is opened in the middle of the base plate 1, and a collection box 7 is fixed at the bottom. In this step, pushing the control lever 51 can drive the cleaning plate 52 to clean the base plate 1. Dust and debris fall into the collection box 7 through the collection hole, keeping the steel ruler plate installation area clean, avoiding dust covering the scale or interfering with pointer observation, and improving the convenience of equipment maintenance and the accuracy of observation.

[0025] like Figure 2 As shown, a filling guide block 6 is fixedly connected to the top of the base plate 1. The filling guide block 6 is disposed between the two cleaning plates 52. During operation, the filling guide block 6 is welded to the top of the base plate 1 and disposed between the two cleaning plates 52. This step allows the filling guide block 6 to guide the cleaning plates 52 to sweep debris towards the collection hole, thereby improving cleaning efficiency, ensuring that the area around the steel ruler plate is clean, and making the scale clearly visible.

[0026] like Figure 2 As shown, the collection assembly includes a collection box 7, a collection hole is provided in the middle of the base plate 1, and the collection box 7 is fixed to the bottom of the base plate 1. The collection box 7 is positioned corresponding to the collection hole. During operation, the collection box 7 is positioned corresponding to the collection hole. This step allows the collection box 7 to collect debris in a concentrated manner, which is convenient for regular disassembly and cleaning, keeps the steel ruler plate installation area clean for a long time, provides a good environment for accurate observation of cylinder expansion, and reduces maintenance difficulty.

[0027] During operation, multiple sets of evenly distributed telescopic frames 11 are bolted to the top of the base plate 1. A fixed slide rail frame 12 is welded to the top of the telescopic frame 11. A guide rail seat 13 slides along the side wall of the fixed slide rail frame 12, and a cat's paw connector 14 is installed on its top to connect the pointer component of the cylinder cat's paw. A steel ruler plate is added to the side of the fixed slide rail frame 12, and a pointer is installed at the corresponding position on the guide rail seat 13. When the cylinder expands, the cat's paw moves the pointer on the steel ruler plate, allowing for direct observation of the expansion through scale changes. This process allows the telescopic frame 11 to be telescopically adapted to different cylinder heights. The sliding fit between the fixed slide rail frame 12 and the guide rail seat 13, combined with the steel ruler plate-pointer design, enables economical and intuitive observation of cylinder expansion. The structure is robust and highly adaptable. Multiple sets of evenly distributed telescopic frames 11 are provided on the side wall of the fixed slide rail frame 12. Distributed rotating holes 21, each group of rotating holes 21 has a rotating rod 22 that rotates within it. A movable slide rail 2 is welded to the end of the rotating rod 22, and a rotating platform 23 is mounted on its top, connecting to a cat's paw connector 14. A steel ruler plate is added to the side of the movable slide rail 2. The rotating rod 22 can drive the movable slide rail 2 to rotate around the rotating holes 21. The rotating platform 23 can adjust the orientation and angle of the steel ruler plate. This step can be adjusted in multiple dimensions through the rotating rod 22 and the rotating platform 23. The steel ruler plate can adapt to the installation angle and position of different cylinder cat's paws, improving observation flexibility and ensuring accurate correspondence between the pointer and the steel ruler plate. Multiple sets of evenly distributed limiting holes 3 are opened on the side walls of the rotating rod 22 and the fixed slide rail 12. After adjusting the angle of the movable slide rail 2 and the steel ruler plate, the limiting rod 31 is inserted into the corresponding limiting hole 3. The positioning of the rotating rod 22 ensures that the limiting component firmly fixes the adjustment position of the steel ruler plate, preventing external vibrations from causing it to shift and ensuring the stability and reliability of the expansion data reading. Multiple evenly distributed fixing plates 4 are welded to the side wall of the guide rail seat 13. Multiple cleaning brushes 41 are installed on the side wall of each fixing plate 4 via screws. The cleaning brushes 41 contact the slide rail surface of the fixed slide rail frame 12. During this step, as the guide rail seat 13 slides, the cleaning brushes 41 clean dust and debris from the slide rail, ensuring smooth sliding of the guide rail seat 13 and indirectly preventing the pointer from shifting and getting stuck on the steel ruler plate, thus improving the observation accuracy of the expansion data. Two operating levers 51 slide inside the mounting frame 5. A cleaning plate 52 is welded to the side wall of each operating lever 51. A collection hole is opened in the middle of the base plate 1. The receiving box 7 is fixed in place. Pushing the control lever 51 activates the cleaning plate 52 to clean the base plate 1. Dust and debris fall into the collecting box 7 through the collection hole, keeping the steel ruler plate installation area clean and preventing dust from covering the scale or interfering with pointer observation. This improves equipment maintenance convenience and observation accuracy. A filling guide block 6 is welded to the top of the base plate 1, positioned between the two cleaning plates 52. This step allows the filling guide block 6 to guide the cleaning plate 52 to sweep debris towards the collection hole, improving cleaning efficiency and ensuring the area around the steel ruler plate is clean and the scale is clearly visible. The collecting box 7 corresponds to the collection hole, allowing it to collect debris centrally for easy periodic disassembly and cleaning, maintaining the cleanliness of the steel ruler plate installation area over the long term, and providing a good environment for accurate observation of cylinder expansion.Reduce maintenance difficulty.
