Description

Technical Field

[0001] The present invention relates to the technical field of water turbine unit repair, and specifically relates to a multifunctional water turbine unit repair platform. Background Technique

[0002] A water turbine is a power machine that converts the energy of water flow into rotational mechanical energy. When a water turbine unit fails, the water turbine unit can be placed on a repair platform for maintenance.

[0003] However, during the use of the existing repair platform, it can support both ends of the water turbine unit. Since the impeller diameters of water turbine units of different sizes are different, when repairing some water turbine units with larger diameters, the repair platform cannot be height-adjusted, and the impeller of the water turbine unit is likely to touch the ground, so that the water turbine unit cannot be placed on the repair platform, resulting in low functionality. Summary of the Invention

[0004] The purpose of the present invention is to provide a multifunctional water turbine unit repair platform to solve the problem that the repair platform cannot be height-adjusted and cannot support and repair some water turbine units with larger diameters as proposed in the above background technique.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A multifunctional water turbine unit repair platform, comprising:

[0006] A repair platform component, the repair platform component includes a support frame, a repair support table is arranged above the support frame, screw rods are connected to the inner walls at both ends of one side of the support frame, and a synchronous height adjustment component is arranged inside the support frame;

[0007] The synchronous height adjustment component includes a support plate, a lead screw penetrates through the middle of the support plate, a guiding square rod is inserted into the lower part of the lead screw, a fixed rod is fixedly connected to the lower part of the guiding square rod, a nut pair is connected to the outer wall of the lead screw, a large gear is fixedly arranged on the outer wall of the nut pair, six holding rods are evenly fixedly installed on the upper surface of the large gear, a limiting ring is arranged inside the large gear, a small gear meshes with the outer wall of the large gear, and a shaft rod penetrates through the middle of the small gear.

[0008] Preferably, two groups of the repair platform components are provided, and a synchronous height adjustment component is arranged in each group.

[0009] Preferably, the support frames are fixedly connected to each other through screw rods.

[0010] Preferably, the support plate is fixedly connected to the support frame, and the lead screw is slidably connected to the support plate and the guiding square rod respectively.

[0011] Preferably, the upper part of the lead screw is fixedly connected to the repair support platform, and both ends of the fixed rod are fixedly connected to the support frame.

[0012] Preferably, the large gear is rotatably connected to the limit ring, and the limit ring is fixedly connected to the support plate.

[0013] Preferably, the thread directions of the two lead screws are opposite, and the small gear is rotatably connected to the shaft rod.

[0014] Preferably, the lower part of the shaft rod is fixedly connected to the support frame, and the two small gears mesh with each other.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] When the repair platform of the present invention is in use, the two support frames can be abutted against each other first, so that the two small gears mesh with each other. Pass the screw through the two support frames and tighten it. The positions between the two support frames are relatively fixed. According to the diameter of the impeller of the water turbine unit to be repaired, hold the grip on a set of repair platform components and rotate the large gear around the central axis of the limit ring. The large gear drives the nut pair and the small gear to rotate. The nut pair drives the lead screw to move upward, and the lead screw drives the repair support platform to move upward. At the same time, the small gear rotates around the shaft rod, driving the small gear of the other set of synchronous height adjustment components to rotate, so that the repair support platforms on the two repair platform components move synchronously. It can ensure that when the water turbine unit is placed later, the heights at both ends of the water turbine unit are the same and there will be no tilting phenomenon. The height of the repair support platform can be adjusted, which is convenient for supporting and repairing water turbine units of different sizes, improving functionality and practicality.

Detailed implementation mode

[0024] Please refer to Figures 1-6 , an embodiment provided by the present invention: a multifunctional water turbine unit repair platform. The repair platform component 01 and the nut pair 25 used in this application are both products that can be directly purchased on the market. Their principles and connection methods are all prior arts well-known to those skilled in the art, so they will not be elaborated here.

[0025] It includes: a repair platform component 01. The repair platform component 01 includes a support frame 11. After splicing two support frames 11, two small gears 29 mesh with each other. After passing the screw 13 through the two support frames 11 and tightening it, the positions of the two support frames 11 can be fixed. Above the support frame 11, there is a repair support platform 12. At both ends of one side inner wall of the support frame 11, there is a screw 13 connected. Inside the support frame 11, there is a synchronous height adjustment component 02;

[0026] The synchronous height adjustment component 02 includes a support plate 21. Inside the middle of the support plate 21, there is a lead screw 22 passing through. During the movement of the lead screw 22, it can drive the repair support platform 12 to move, thereby adjusting the height of the repair support platform 12, facilitating the support and repair of water turbine units with different diameters. Inside the lower part of the lead screw 22, there is a guiding square rod 23 inserted. The guiding square rod 23 plays a guiding role for the lead screw 22. The guiding square rod 23 is located inside the lead screw 22 to guide the lead screw 22, ensuring that the lead screw 22 can only move up and down. Below the guiding square rod 23, there is a fixed rod 24 fixedly connected. On the outer wall of the lead screw 22, there is a nut pair 25 connected. On the outer wall of the nut pair 25, there is a large gear 26 fixedly arranged. The large gear 26 can rotate around the central axis of the limit ring 28, driving the nut pair 25 to rotate, and then driving the lead screw 22 to move up and down. On the upper surface of the large gear 26, six grip rods 27 are evenly fixedly installed. Inside the large gear 26, there is a limit ring 28. The limit ring 28 plays a guiding and limiting role for the large gear 26, ensuring that the large gear 26 will not easily move in position. On the outer wall of the large gear 26, there is a small gear 29 meshing. The small gear 29 can rotate around the central axis of the shaft rod 30, thereby driving the small gear 29 on another group of synchronous height adjustment components 02 to rotate. Inside the middle of the small gear 29, there is a shaft rod 30 passing through. The shaft rod 30 plays a supporting role for the small gear 29. The two small gears 29 mesh with each other, ensuring that the two small gears 29 can drive each other to rotate, and then driving the large gear 26 of another group of synchronous height adjustment components 02 to rotate.

[0027] Further, there are two sets of repair platform components 01, and a synchronous height adjustment component 02 is arranged in each set. The two repair platform components 01 can support both ends of the water turbine unit to ensure the stability of the support.

[0028] Further, the support frames 11 are fixedly connected to each other through screws 13. After the two support frames 11 are spliced, the two small gears 29 mesh with each other. After the screw 13 passes through the two support frames 11 and is tightened, the positions of the two support frames 11 can be fixed.

[0029] Further, the support plate 21 is fixedly connected to the support frame 11 to ensure the firmness of the position of the support plate 21. The lead screws 22 are respectively slidably connected to the support plate 21 and the guiding square rod 23. The guiding square rod 23 plays a guiding role for the lead screw 22. The guiding square rod 23 is located inside the lead screw 22 to guide the lead screw 22 and ensure that the lead screw 22 can only move up and down.

[0030] Further, the upper part of the lead screw 22 is fixedly connected to the repair support platform 12 to ensure that during the movement of the lead screw 22, the repair support platform 12 can be driven to move, thereby adjusting the height of the repair support platform 12, facilitating the support and repair of water turbine units with different diameters. The two ends of the fixing rod 24 are fixedly connected to the support frame 11 to ensure the firmness of the position of the fixing rod 24.

[0031] Further, the large gear 26 is rotatably connected to the limit ring 28. The large gear 26 can rotate around the central axis of the limit ring 28 to drive the nut pair 25 to rotate, and then drive the lead screw 22 to move up and down. The limit ring 28 is fixedly connected to the support plate 21 to ensure the firmness of the position of the limit ring 28. The limit ring 28 plays a guiding and limiting role for the large gear 26 to ensure that the large gear 26 will not move easily.

[0032] Further, the thread directions of the two lead screws 22 are opposite. There are two small gears 29, and the rotation directions of the large gears 26 on the two sets of synchronous height adjustment components 02 are different and the thread directions are opposite. In the case of different rotation directions of the large gears 26, the lead screws 22 can still be driven to move synchronously. The small gear 29 is rotatably connected to the shaft rod 30. The small gear 29 can rotate around the central axis of the shaft rod 30 to drive the small gear 29 on the other set of synchronous height adjustment components 02 to rotate.

[0033] Further, the lower part of the shaft rod 30 is fixedly connected to the support frame 11 to ensure the firmness of the position of the shaft rod 30. The shaft rod 30 plays a supporting role for the small gear 29. The two small gears 29 mesh with each other to ensure that the two small gears 29 can drive each other to rotate, and then drive the large gear 26 on the other set of synchronous height adjustment components 02 to rotate.

[0034] Working principle: When in use, first make the two support frames 11 abut against each other so that the two small gears 29 mesh with each other. Pass the screw rod 13 through the two support frames 11 and tighten it, so that the positions between the two support frames 11 are relatively fixed. According to the diameter of the impeller of the water turbine unit to be repaired, hold the grip rod 27 on a set of repair platform assemblies 01 and rotate the large gear 26 around the central axis of the limit ring 28. The large gear 26 drives the nut pair 25 and the small gear 29 to rotate. The nut pair 25 drives the lead screw 22 to move upward, and the lead screw 22 drives the repair support platform 12 to move upward. At the same time, the small gear 29 rotates around the shaft rod 30, driving the small gear 29 of the other set of synchronous height adjustment assemblies 02 to rotate, so that the repair support platforms 12 on the two repair platform assemblies 01 move synchronously. After that, unscrew the screw rod 13, separate the two support frames 11 and place them at both ends of the water turbine unit to support the water turbine unit.
