Abstract
Description
Technical Field
[0001] This utility model relates to the field of steam turbine maintenance technology, specifically a steam turbine maintenance device. Background Technology
[0002] The turbine EH oil system, also known as the turbine speed regulating oil system or high-pressure fire-resistant oil system, is named so because the turbine's speed regulating oil system and lubrication oil system are independent. It uses high-temperature resistant fire-resistant oil and employs high oil pressure to control the turbine's main steam valves and speed regulating valves. The key component of the oil supply system is the filter, which removes impurities from the fire-resistant oil. During maintenance, the filter needs to be removed. However, because fire-resistant oil remains inside the filter, direct removal for maintenance in the operating environment can easily lead to fire-resistant oil leakage onto the working surface, causing serious pollution and making manual cleaning difficult.
[0003] Based on the authorized patent CN202321270436.3 "A steam turbine maintenance device", this utility model provides a steam turbine maintenance device that solves the problem that the dismantling and maintenance of existing devices easily leads to the leakage of fire-resistant oil on the working environment ground, causing serious pollution of the working surface and making manual cleaning difficult.
[0004] The above technical solution requires the equipment to be placed on top of the workbench during use, which necessitates clamping the workpiece on top of the workbench. However, due to the different sizes of steam turbines, clamping the workpiece wastes a lot of time, thus affecting the progress of maintenance.
[0005] Therefore, this utility model provides a steam turbine maintenance device. Utility Model Content

[0015] Beneficial effects
[0016] Compared with the prior art, the present invention has the following advantages:
[0017] (1) This turbine maintenance device is equipped with a workbench. When a workpiece needs to be maintained, the workpiece is first placed inside the workpiece slot. The controller starts the motor on the outside of the connecting plate, which drives the double-acting screw to rotate. The rotation of the double-acting screw drives the collar to rotate. A limit rod is fixedly connected to the bottom of the collar. The bottom of the limit rod is slidably connected inside the moving slot. Therefore, the double-acting screw can drive the collar to move closer or further away from each other. At this time, the L-shaped rod will drive the clamping cover at the bottom of the lifting rod to move outside the workpiece. The clamping cover moves to the top two ends of the workpiece. Then, the controller starts the electric telescopic rod, which drives the lifting rod to move the clamping cover to the top of the workpiece, thus achieving the effect of convenient clamping of the workpiece. When the clamping position needs to be adjusted, the motor drives the double-acting screw to rotate, which allows the collar to drive the clamping cover to adjust the clamping position.
[0018] (2) The turbine maintenance device is equipped with a workbench. The controller starts the extraction pump on the outside of the water tank. At this time, the water inside the water tank can be sprayed out through the water spray plate on the outside of the extraction pump to clean the workpiece inside the workpiece tank. The wastewater after cleaning will enter the collection box through the leakage hole and then be discharged through the drain pipe to prevent impurities in the wastewater from remaining on the surface of the workbench and causing a poor environment.

[0026] The clamping mechanism 5 includes a connecting plate 51, a motor 52 is fixedly connected to the outer side of the connecting plate 51, a bidirectional lead screw 53 is fixedly connected to the output end of the motor 52, a collar 54 is threadedly connected to the outer side of the bidirectional lead screw 53, a limit rod 55 is fixedly connected to the bottom of the collar 54, a moving groove 56 is provided in the top wall of the operating box 3, an L-shaped rod 57 is fixedly connected to the outer side of the collar 54, an electric telescopic rod 58 is fixedly connected to the bottom of the L-shaped rod 57, a lifting rod 59 is fixedly connected to the output end of the electric telescopic rod 58, and a clamping cover 510 is fixedly connected to the bottom of the lifting rod 59.
[0027] Furthermore: support columns 2 are symmetrically distributed at the bottom of workbench 1, connecting plates 51 are symmetrically distributed at the top of rotating box 3, bidirectional lead screw 53 is rotatably connected between the two connecting plates 51, collars 54 are symmetrically distributed on the outside of bidirectional lead screw 53, the bottom of limit rod 55 is slidably connected to the inside of moving groove 56, and clamping cover 510 is symmetrically distributed on the outside of rotating box 3.
[0028] It should be noted that the support columns 2, distributed at the bottom of the worktable 1, can provide stable support for the worktable 1. By starting the motor 52, the motor 52 drives the bidirectional lead screw 53 to rotate between the two connecting plates 51. The limiting rod 55 is slidably connected inside the moving groove 56, which can limit the movement of the collar 54 on the outside of the bidirectional lead screw 53.
[0029] As a further improvement of this utility model, a cleaning mechanism 6 is provided on the outer side of the workbench 1. The cleaning mechanism 6 includes a drain hole 61. A stabilizing plate 62 is fixedly connected to the top of the workbench 1. A water storage tank 63 is fixedly connected to the outer side of the stabilizing plate 62. A pump 64 is fixedly connected to the outer side of the water storage tank 63. A scale plate 65 is fixedly connected to the outer side of the water storage tank 63. A spray plate 66 is fixedly connected to the outer side of the pump 64. A fixing plate 67 is fixedly connected between the support columns 2. A collection box 68 is fixedly connected to the top of the fixing plate 67. A drain pipe 69 is fixedly connected to the outer side of the collection box 68. A suction pipe 610 is fixedly connected to one end of the drain pipe 69 inside the collection box 68.
[0030] Furthermore: the leak holes 61 are evenly distributed in the inner wall of the workpiece groove 7, the extraction pump 64 is electrically connected to the controller 4, the water spray plate 66 is located on the top outer side of the workpiece groove 7, and the collection box 68 is located directly below the leak holes 61.
[0031] It should be noted that: the pump 64 is started by the controller 4, thereby drawing water out of the water tank 63 and into the spray plate 66. The water sprayed by the spray plate 66 can clean the workpiece, while the sewage will enter the collection box 68 through the drain hole 61.
[0032] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0033] Working Principle: With a worktable 1 in place, when a workpiece needs repair, it is first placed inside the workpiece slot 7. The controller 4 starts the motor 52 on the outside of the connecting plate 51, causing the motor 52 to rotate the bidirectional lead screw 53. The rotation of the bidirectional lead screw 53 causes the collar 54 to rotate. A limit rod 55 is fixedly connected to the bottom of the collar 54, and the bottom of the limit rod 55 is slidably connected inside the moving slot 56. Therefore, the bidirectional lead screw 53 can move the collar 54 closer together or further apart. This causes the L-shaped rod 57 to move the clamping cover 510 at the bottom of the lifting rod 59 outside the workpiece, moving the clamping cover 510 to the top two ends of the workpiece. Then, the controller 4 starts the electric telescopic rod 58, thereby... The lifting rod 59 moves the clamping cover 510 to the top of the workpiece, achieving the effect of convenient clamping of the workpiece. When the clamping position needs to be adjusted, the motor 52 drives the bidirectional lead screw 53 to rotate, which causes the collar 54 to drive the clamping cover 510 to adjust the clamping position. By setting up the worktable 1, the controller 4 starts the extraction pump 64 on the outside of the water tank 63. At this time, the water inside the water tank 63 can be sprayed out through the water spray plate 66 on the outside of the extraction pump 64, thereby cleaning the workpiece inside the workpiece groove 7. The wastewater after cleaning will enter the collection box 68 through the drain hole 61 and then be discharged through the drain pipe 69, preventing impurities in the wastewater from remaining on the surface of the worktable 1 and causing a poor environment.
