Description

Technical Field

[0001] This invention relates to the field of turbine blade maintenance technology, specifically to a turbine blade maintenance device that is easy to operate. Background Technology

[0002] A turbine is a device that uses fluid kinetic energy to generate mechanical work. Based on the turbine principle, it converts the kinetic energy of the fluid into rotational motion on a shaft. During operation, the turbine blades drive the fluid movement. Because the space where the turbine blades gather is small, the large driving force of the turbine blades during operation causes impurities and dust in the air to come into contact with the blade surface. These impurities and dust easily accumulate at the blade gathering point. Due to the limited space for the turbine blades' installation and arrangement, cleaning is quite difficult. Furthermore, the large number of blades makes cleaning and maintenance time-consuming, which cannot effectively improve the efficiency of turbine blade maintenance.

[0003] Therefore, an easy-to-operate turbine blade maintenance device was proposed to solve the above problems. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides an easy-to-operate turbine blade maintenance device. After completing the maintenance operation at one set of blade gaps, the device adjusts its position and automatically moves to the next set of blade gaps to perform the maintenance operation again. This improves operational efficiency and facilitates the maintenance of turbine blades, thereby solving the problems mentioned in the background art.

[0009] Preferably, the grinding and oiling mechanism includes a first motor, the output end of which is connected to a first bevel gear, the top of which meshes with a second bevel gear, the second bevel gear being rotatably connected to the end of a push rod, a grinding head being fixedly connected to one side of the first bevel gear, a mounting bracket being fixedly connected to the top of the second bevel gear, oil rollers being sleeved on both sides of the top of the mounting bracket, an oil tank being fixedly installed on the top of the mounting bracket, and transmission pipes being installed on both sides of the oil tank, with the end of the transmission pipe away from the oil tank communicating with the interior of the oil roller.

[0010] Preferably, the limiting mechanism includes a support frame, which is fixedly installed on the side of the bearing cylinder. A spring is sleeved on the support frame, and a baffle is hinged to one end of the support frame. Several limiting mechanisms are provided, which are used to keep the control components running smoothly during the maintenance of the device.

[0011] Preferably, the displacement auxiliary disk has several grooves that match the shape of the traveling cylinder, and the traveling cylinder is in frictional connection with the displacement auxiliary disk.

[0012] Preferably, the impurity collection mechanism includes a second motor, the end of which is mounted at the axis of the bearing cylinder, and a fan blade is mounted at the output end of the second motor. The impurity collection mechanism also includes a protective cover, which is detachably mounted at the axis of the bearing cylinder. Several slots are opened laterally on the protective cover, and a collection box is installed at the bottom of the protective cover. The collection box communicates with the interior of the protective cover.

[0013] Preferably, the lower part of the ejector rod is semi-cylindrical, and the bottom of the ejector rod is fulcrumd with a three-headed rotating rod, which facilitates the ejector rod to eject and move the bearing seat.

[0014] Preferably, the number of grooves on the shifting auxiliary disk is adapted to the number of limiting mechanisms.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides an easy-to-operate turbine blade maintenance device, which has the following beneficial effects:

[0017] 1. In this invention, after grinding and oiling a section of the turbine blade assembly, the toothed plate drives the rotating wheel to rotate, causing the ejector rod fixed at the bottom of the rotating wheel to rotate. The surface of the ejector rod rubs against the bottom of the bearing seat and uses the three-headed rotating rod as a fulcrum to push the bearing seat out, causing one end of the bearing seat to push the baffle open and compress the spring. After the bearing seat passes, the baffle returns to its original position and limits the bearing seat. After completing the maintenance operation at the gap of a set of blades, the position is adjusted and automatically adjusted to the next set of blade gaps to perform the maintenance operation again. This can improve the operating efficiency and facilitate the maintenance operation of the turbine blades.

[0018] 2. In this invention, the first motor drives the first bevel gear to rotate, causing the grinding head to rotate rapidly. When it comes into contact with the slot of the turbine blade, it generates friction with the impurities attached to it, thus grinding away the more stubborn deposits. At the same time, while the grinding head is grinding, the first bevel gear drives the meshing second bevel gear to rotate, causing the oil cylinder above the second bevel gear to leak oil and roll it onto the surface of the blade, thus lubricating and maintaining the blade. This can save corresponding operation time and maintain the blade in good condition.

[0019] 3. In this invention, during the grinding process, the second motor is started to drive the fan blades to rotate. The fan blades quickly introduce external air into the interior of the protective cover. During this process, impurities generated during grinding splash out from the slots of the turbine blades and are sucked into the protective cover, which can quickly clean the maintenance site environment and prevent dirt and mess.

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0037] Example 1:

[0038] Please refer to Figures 1 to 4 , Figure 6 , Figure 7 As shown:

[0039] To address the problems mentioned in the technical solutions, this application provides an easy-to-operate turbine blade maintenance device, including a base 1, a bearing cylinder 2 fixedly installed on the top of the base 1, a control component 3 and a limiting mechanism 4 respectively provided on the bearing cylinder 2, one end of the control component 3 being frictionally connected to the limiting mechanism 4, a displacement auxiliary disk 5 fixedly installed inside the bearing cylinder 2, and an impurity collection mechanism 6 fixedly installed at the end of the bearing cylinder 2 away from the limiting mechanism 4.

[0040] The control component 3 includes a support base 301. A sliding rod 302 is connected through the bottom of one side of the support base 301. The sliding rod 302 is movably sleeved with the support cylinder 2. An electric cylinder 303 is fixedly installed on the top of the support base 301. A push rod 304 is connected to the output end of the electric cylinder 303. The push rod 304 is slidably installed above the support base 301. A grinding and oiling mechanism 305 is provided at the end of the push rod 304 away from the electric cylinder 303. A toothed plate 306 is fixedly installed on the side of the push rod 304. A three-headed rotating rod 307 is rotatably installed at the bottom of the support base 301. A traveling cylinder 308 is movably sleeved on the three-headed rotating rod 307. There are three traveling cylinders 308. A rotating wheel 309 is sleeved on the side of the support base 301. The rotating wheel 309 meshes with the toothed plate 306. An ejector rod 310 is fixedly installed at the bottom of the rotating wheel 309. The end of the support base 301 away from the sliding rod 302 is slidably connected to the support cylinder 2.

[0041] The grinding and oiling mechanism 305 includes a first motor 3051, the output end of which is connected to a first bevel gear 3052, the top of which is meshed with a second bevel gear 3053, the second bevel gear 3053 being rotatably connected to the end of a push rod 304, a grinding head 3054 being fixedly connected to one side of the first bevel gear 3052, a mounting bracket 3055 being fixedly connected to the top of the second bevel gear 3053, oil rollers 3056 being sleeved on both sides of the top of the mounting bracket 3055, an oil tank 3057 being fixedly installed on the top of the mounting bracket 3055, and a transmission pipe 3058 being installed on both sides of the oil tank 3057, the end of the transmission pipe 3058 away from the oil tank 3057 being connected to the interior of the oil roller 3056.

[0042] The shifting auxiliary disk 5 has several grooves that match the shape of the traveling cylinder 308, and the traveling cylinder 308 is in frictional connection with the shifting auxiliary disk 5.

[0043] The lower part of the ejector rod 310 is set in a semi-cylindrical shape. The bottom of the ejector rod 310 is fulcrumd with a three-headed rotating rod 307, which makes it easy for the ejector rod 310 to eject and move the bearing seat 301.

[0044] In this embodiment, the length of the toothed plate 306 is only a small segment. When the push rod 304 is retracted to near the end by the electric cylinder 303, the toothed plate 306 meshes with the rotating wheel 309 that is sleeved on the side of the bearing seat 301, so that the rotating wheel 309 is driven, and the ejector rod 310 connected to the bottom of the rotating wheel 309 rotates and contacts the bottom of the bearing seat 301, and ejects the bearing seat 301.

The limiting mechanisms 4 are used to keep the control component 3 running smoothly during the maintenance of the device.

[0049] The number of grooves on the shifting auxiliary disk 5 is matched with the number of limiting mechanisms 4.

[0050] In this embodiment, the limiting mechanism 4 only starts working when the carrier 301 is pushed out, and after the carrier 301 passes the baffle 403, the baffle 403 returns to its initial position to limit the carrier 301, thus maintaining stability during the maintenance operation.

[0051] Further embodiments

[0052] Please refer to Figure 8 As shown:

[0053] The impurity collection mechanism 6 includes a second motor 601, the end of which is mounted at the axis of the bearing cylinder 2. A fan blade 602 is mounted at the output end of the second motor 601. The impurity collection mechanism 6 also includes a protective cover 603, which is detachably mounted at the axis of the bearing cylinder 2. Several slots are opened laterally on the protective cover 603. A collection box 604 is installed at the bottom of the protective cover 603, and the collection box 604 communicates with the interior of the protective cover 603.

[0054] In this embodiment, the protective cover 603 has several slots opened horizontally, which not only suck in splashed material but also improve operational safety. The collection box 604 is designed to be detachable.

[0055] The working principle of all the content in the above embodiments is as follows:

[0056] In the initial state: the support seat 301 is fixed in the limiting mechanism 4, the two baffles 403 are parallel to each other, and the push rod 304 is not extended.

[0057] Before operation, the operator injects lubricating oil for blade maintenance into the oil tank 3057. The device is then adjusted so that the grinding head 3054 aligns with the groove at the turbine blade connection. The electric cylinder 303 and the first motor 3051 are then activated. The electric cylinder 303 drives the push rod 304 connected to its output end to move laterally towards the turbine blade, causing the push rod 304 to slide on the support 301. The first motor 3051 drives the first bevel gear 3052 connected to its output end to rotate, causing the grinding head 3054 mounted on the first bevel gear 3052 to rotate rapidly. As the push rod 304 is driven to continuously move towards the turbine blade, the surface of the rapidly rotating grinding head 3054 contacts the turbine blade. The material adhering to the grooves of the turbine blades is subjected to significant friction, causing the material within the grooves to be abraded. Simultaneously, as the first bevel gear 3052 rotates, it drives the second bevel gear 3053 meshing above it to rotate. This causes the mounting bracket 3055, fixedly connected to the second bevel gear 3053, to rotate around the center point of the second bevel gear 3053. During the rotation of the mounting bracket 3055, the oil rollers 3056 mounted on both sides above it lightly brush against the turbine blades. The rotation causes the lubricating oil inside the oil tank 3057 to be ejected and transported through the transmission pipe 3058 to the oil rollers 3056. When the oil rollers 3056 contact the turbine blades, they coat the blade surface with lubricating oil, thus improving the condition of the grooves. While grinding, the blades are also maintained. After the grinding head 3054 finishes grinding a groove, the electric cylinder 303 controls the push rod 304 to retract. During the retraction process, the toothed plate 306 mounted on the side of the push rod 304 meshes with the rotating wheel 309. The lateral movement of the toothed plate 306 causes the rotating wheel 309 to rotate. At this time, the ejector rod 310 connected to the bottom of the rotating wheel 309 rotates synchronously with the rotating wheel 309. The special shape of the lower part of the ejector rod 310 allows it to push out the bearing seat 301 with the position of contact with the three-head rotating rod 307 as the fulcrum during rotation. The three-head rotating rod 307 rotatably mounted at the bottom of the bearing seat 301 rotates and is subjected to lateral thrust, causing the traveling cylinder 308 mounted on the three-head rotating rod 307 to... The center point of the three-headed rotating rod 307 rotates and then falls back into the groove opened on the shifting auxiliary plate 5. At the same time, when the bearing seat 301 is pushed by the lateral force, it pushes the baffle 403 open, so that the spring 402 is compressed. After the bearing seat 301 completes the movement, the side of the bearing seat 301 is disconnected from the baffle 403. Under the force of the spring 402, the baffle 403 returns to its original position, so that the bearing seat 301 will not move. After the bearing seat 301 and the components above it are pushed to move a small distance with the axis of the bearing cylinder 2 as the reference, the push rod 304 is controlled to move again towards the turbine blade to perform grinding and oiling processes. This is easier to operate for turbine units with many blades and slots.

[0058] Furthermore, during the polishing process, due to the high friction, the material adhering to the groove will splash everywhere, causing a mess on site. The operator starts the second motor 601 to work. The fan blade 602 installed on the second motor 601 rotates and sucks the splashed impurities into the interior of the protective cover 603. After entering the interior of the protective cover 603, the splashed impurities fall down the bottom of the protective cover 603 into the collection box 604 for collection.

[0059] Overview:

[0060] In this invention, through the control component 3, after grinding and oiling a section of the turbine blade assembly, the toothed plate 306 drives the rotating wheel 309 to rotate, causing the ejector rod 310 fixed at the bottom of the rotating wheel 309 to rotate. The surface of the ejector rod 310 rubs against the bottom of the support seat 301 and uses the three-headed rotating rod 307 as a fulcrum to push the support seat 301 out, causing one end of the support seat 301 to push the baffle 403 open and compress the spring 402. After the support seat 301 passes, the baffle 403 returns to its original position and limits the support seat 301. After completing the maintenance operation of one area, the position is adjusted and the second area is automatically maintained again, which can improve the operation efficiency. Through the impurity collection mechanism 6, impurities splashed during the grinding process can be collected to prevent them from scattering everywhere and improve the cleanliness of the maintenance process.
