Description

Technical Field

[0001] The utility model relates to supporting equipment for vertical water pump maintenance, in particular to supporting equipment for vertical water pump maintenance, and belongs to the technical field of vertical water pump maintenance. Background Art

[0002] There are many types of conventional vertical water pumps in power plants, including vertical pipeline centrifugal pumps, vertical circulating water pumps and other specially designed vertical pumps. These pumps work together to ensure the stable operation and water treatment efficiency of the power plant based on their specific application scenarios and performance parameters. In order to ensure the normal use of conventional vertical water pumps in power plants, the vertical water pumps will be overhauled, and support equipment will be used to support the overhauled vertical water pumps.

[0003] The support device for the maintenance of a vertical water pump disclosed in the Chinese patent application publication specification CN220945271U fastens the vertical water pump through a clamping mechanism connected to a mounting plate after the vertical water pump passes through the accommodating window. The clamping mechanism includes two clamping parts, which are symmetrically arranged on both sides of the accommodating window and can move in opposite directions in the accommodating window to move to abut against the vertical water pump, thereby fixing the vertical water pump passing through the accommodating window, so that the vertical water pump can be disassembled and assembled in a small space to prevent it from tipping over.

[0004] However, during the implementation of the technical solution of the above patent, it is impossible to ensure that various vertical water pumps can be stably clamped and supported. The existing supporting equipment will clamp and lift the vertical water pump to facilitate the maintenance of the vertical water pump. There are many types of conventional vertical water pumps in power plants, and the clamping plate of the supporting equipment cannot fit tightly to the outer surfaces of various vertical water pumps. When the clamping plate cannot fit the vertical water pump well, the stability of the vertical water pump cannot be guaranteed. Subsequent maintenance may shake the vertical water pump, and there is even a risk of it falling. Utility Model Content

[0005] The purpose of the utility model is to provide a support device for vertical water pump maintenance in order to solve the above problems, so as to solve the problem that the clamping plate of the support device in the prior art cannot be replaced to adapt to various vertical water pumps, resulting in a small scope of application.

When the two internally threaded moving blocks on the same bidirectional screw approach or move away from each other, the mounting frame will be driven away from or close to the fixed box.

[0009] Furthermore, the inner walls of the two fixed boxes are fixedly connected with guide rods, which penetrate the internal thread moving block and are slidably connected to the internal thread moving block, and the guide rods play a guiding role in the movement of the internal thread moving block.

[0010] The above-mentioned clamping mechanism also includes two sprockets. The ends of the two bidirectional screws close to the sprockets respectively pass through the two fixed boxes and are fixedly connected to the outer surfaces of the two sprockets. The two sprockets are connected by chain transmission. Under the action of the two sprockets and the chain, the two bidirectional screws can rotate synchronously.

[0028] Please refer to Figure 1 , Figure 2 and Figure 3, including a U-shaped frame 1, a clamping mechanism 2 is arranged above the U-shaped frame 1, the clamping mechanism 2 includes two mounting frames 22 and two fixing boxes 21 fixedly connected to the upper surface of the U-shaped frame 1, the inner walls of the two mounting frames 22 are slidably connected with clamping blocks 23, the outer surfaces of the two clamping blocks 23 are fixedly connected with clamping plates 24, and the clamping plates 24 can be replaced to adapt to various types of vertical water pumps.

[0029] The inner walls of the two fixed boxes 21 are rotatably connected with bidirectional screws 25, and the outer surfaces of the two bidirectional screws 25 are threadedly connected with two symmetrical internally threaded moving blocks 26. The outer surfaces of the two mounting frames 22 are hinged with connecting rods 27, and the ends of the four connecting rods 27 away from the mounting frames 22 are respectively hinged on the outer surfaces of the four internally threaded moving blocks 26. When the two internally threaded moving blocks 26 on the same bidirectional screw 25 approach or move away from each other, the mounting frame 22 will be driven away from or close to the fixed box 21.

[0030] The inner walls of the two fixed boxes 21 are fixedly connected with guide rods 28 , which penetrate the internal thread moving block 26 and are slidably connected to the internal thread moving block 26 , and the guide rods 28 guide the movement of the internal thread moving block 26 .

[0031] The above-mentioned clamping mechanism 2 also includes two sprockets 211. A servo motor is arranged on the U-shaped frame 1 to provide power for the rotation of the sprocket 211. The ends of the two bidirectional screws 25 close to the sprocket 211 respectively penetrate the two fixed boxes 21 and are respectively fixedly connected to the outer surfaces of the two sprockets 211. The two sprockets 211 are connected by a chain transmission. Under the action of the two sprockets 211 and the chain, the two bidirectional screws 25 can rotate synchronously. When the two bidirectional screws 25 rotate synchronously, the two groups of internal thread moving blocks 26 will approach or move away from each other at the same time.

[0032] Two guide seats 29 are fixedly connected to the upper surfaces of the two fixed boxes 21, and two sliding plates 210 are fixedly connected to the outer surfaces of the two mounting frames 22. The four sliding plates 210 are respectively slidably connected to the inner walls of the four guide seats 29, and the guide seats 29 and the sliding plates 210 serve as guides for the movement of the mounting frames 22.

[0033] Please refer to Figure 2 , Figure 3 and Figure 4 A limiting assembly 3 is provided on the outside of the two mounting frames 22. The limiting assembly 3 includes a limiting rod 31 and a hinge seat 32 fixedly connected to the outer surface of the mounting frame 22. The limiting rod 31 passes through the mounting frame 22 and is slidably connected to the mounting frame 22. The limiting rod 31 is adapted to the clamping block 23. The clamping block 23 is provided with a limiting hole adapted to the limiting rod 31. The clamping block 23 can be fixed in the mounting frame 22 by inserting the limiting rod 31 into the limiting hole of the clamping block 23.

[0034] A pressing frame 33 is hinged on the inner wall of the hinged seat 32, and a fixing rod 34 is fixedly connected to the inner wall of the limiting rod 31. The fixing rod 34 is slidably connected to the inner wall of the pressing frame 33.

[0035] A spring 35 is fixedly connected to a side of the pressing frame 33 close to the mounting frame 22 , and an end of the spring 35 away from the pressing frame 33 is fixedly connected to the outer surface of the mounting frame 22 . The setting of the spring 35 can prevent the limiting rod 31 from being unintentionally separated from the clamping block 23 .

[0036] Please refer to Figure 1 A movable base 4 is provided below the U-shaped frame 1, and four hydraulic rods 5 are fixedly connected to the upper surface of the movable base 4. The top ends of the four hydraulic rods 5 are fixedly connected to the bottom surface of the U-shaped frame 1. The four hydraulic rods 5 share the same controller, so that the four hydraulic rods 5 can be extended and retracted synchronously.

[0037] Working principle: Press the pressing frame 33 to compress the spring 35. At this time, the pressing frame 33 will pull the limiting rod 31 to move away from the clamping block 23 through the fixing rod 34. The limiting rod 31 is pulled out of the limiting hole of the clamping block 23. Then the clamping block 23 can be taken out and the clamping plate 24 can be replaced so that the clamping plate 24 can fit the outer surface of the vertical water pump. The clamping block 23 is installed in the mounting frame 22. Under the elastic force of the compressed spring 35, the limiting rod 31 is pushed to be inserted into the clamping block 23 again.

[0038] Then, the servo motor on the U-shaped frame 1 is controlled to operate, and under the transmission action of the two sprockets 211 and the chain, the two bidirectional screws 25 are rotated synchronously, and the two internal thread moving blocks 26 on the same bidirectional screw 25 are close to each other, and the clamping plate 24 is driven to approach the vertical water pump through the connecting rod 27, so that the two clamping plates 24 clamp and fix the vertical water pump, and then the four hydraulic rods 5 are controlled to extend synchronously to lift the vertical water pump, and then the maintenance work can be carried out. The device can replace the appropriate clamping plate 24 according to the type of the vertical water pump, so that the clamping plate 24 is more in line with the outer surface of the vertical water pump, thereby ensuring the stability of the support for the vertical water pump.
