Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water conservancy machinery, in particular to a segmented disconnection pipe push-pull maintenance operation system for lifting and lowering of a submersible pump. BACKGROUND

[0002] In the fields of water conservancy projects, municipal water supply, industrial circulating water, etc., as an important water storage and water supply facility, the stable operation of the submersible pump inside the high-level pool is directly related to the reliability of the water supply system. The submersible pump is operated in the underwater or humid environment for a long time, and needs to be regularly maintained or replaced due to problems such as impeller wear, motor failure, and aging of sealing elements. Since the high-level pool usually has a large depth and height difference, the installation and maintenance of the submersible pump has always been a technical difficulty in the industry.

[0003] The existing push-pull maintenance trolley system lacks a dedicated integrated solution for pipe handling, and the disassembly and installation of the pipe completely rely on manual operation or additional auxiliary equipment such as cranes and jacks. Specifically, when the submersible pump is moved to the maintenance position, the operator needs to manually disassemble the bolts at the flange connection of the pipe, and after the pipe and the submersible pump are separated, the pipe needs to be lifted manually or a crane needs to be called to move the pipe to a temporary storage area. When installing, the above process needs to be repeated in reverse, i.e., the pipe is hoisted to the docking position, the pipe posture is adjusted manually to realize accurate docking with the submersible pump, and finally the bolts are fastened.

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1-4 A segmented disassembly and retraction maintenance operating system for raising and lowering a submersible pump includes: a support mechanism for supporting the system, comprising a base 1, a side support plate 6, and a side support frame 7; a raising mechanism for raising and lowering the submersible pump, comprising a winch 2 for retrieving a steel cable 5, a guide wheel 3 and a guide roller 4 inside the base 1 for controlling the direction of movement of the steel cable 5, and an infrared sensor 19 mounted on the base 1; a lifting mechanism for transporting the submersible pump pipeline, mounted on the top of the base 1, comprising a roller frame 20 and a trolley mechanism; and a disassembly and assembly mechanism, mounted on the top of the side support plate 6 for assisting in the disassembly and assembly of the pipeline, comprising a moving mechanism and a fixing mechanism; the moving mechanism includes a lead screw 9 rotatably connected to the top of the side support plate 6, and the top of the side support plate 6 is fixed. A slide rail 12 is fixedly connected to the top of the side support plate 6. A motor 8 is fixedly connected to the top of the side support plate 6. The motor 8 is used to control the rotation of the lead screw 9. A wedge-shaped support rod 13 is slidably connected to the top of the slide rail 12. A connecting rod 11 is fixedly connected to the outer wall of the wedge-shaped support rod 13. The connecting rod 11 is threadedly connected to the lead screw 9. The fixing mechanism includes a fixed gripper 14 and a movable gripper 17. The fixed gripper 14 and the movable gripper 17 are rotatably connected. One side of the fixed gripper 14 is fixedly installed on the top of the wedge-shaped support rod 13. A cylinder 15 is rotatably connected to the outer wall of the fixed gripper 14. A coupling 16 is fixedly connected to the output end of the cylinder 15. The coupling 16 is rotatably connected to the movable gripper 17. A conveyor belt 18 is installed inside the side support frame 7 for transporting the disassembled pipe. A buffer mechanism is installed inside the side support frame 7 to buffer the pipe falling onto the conveyor belt 18.

[0026] In this embodiment, during the operation of the push-pull maintenance system, the winch 2 will start and drive the steel cable 5, so that the steel cable 5 can effectively pull the submersible pump. At the same time, the system guides the steel cable 5 with the guide wheel 3 and guide roller 4 to ensure that the steel cable 5 remains stable during the pulling process. When the submersible pump is gradually pulled up, the pipes connected to it will also be lifted. These pipes are firmly fixed on the fixing plate 23 and fixed with the fixing frame 24. In order to ensure the stability of the pipes, the fixing frame 24 and the fixing plate 23 can be tightened and fixed with bolts 25, thereby achieving a stable fixation of the pipes.

[0027] After the pipe is fixed, the rollers 21 on both sides of the connecting shaft 22 will roll on the roller frame 20, so that the pipe can be pulled up smoothly. In order to control the lifting distance of the pipe, the system is equipped with an infrared sensor 19 to detect the distance of the steel cable 5 being retracted, thereby achieving precise control of the specific lifting distance of the pipe and facilitating the orderly disassembly of each section of the pipe.

[0028] When the pipe stops moving, the motor 8 drives the lead screw 9, which in turn controls the connecting rod 11 to move. The connecting rod 11 then drives the wedge-shaped support rod 13 to slide smoothly along the slide rail 12 and extend to the bottom of the pipe to lift it up. Subsequently, the cylinder 15 controls the movable gripper 17 to rotate, thereby firmly clamping and fixing the pipe for easy disassembly.

[0029] After the pipe is disassembled, the control system will instruct the movable gripper 17 to rotate and open. At this time, the inclined design of the wedge support rod 13 will cause the pipe to roll onto the conveyor belt 18. In order to prevent the pipe from rolling off the surface of the conveyor belt 18, side support frames 7 are set on both sides of the conveyor belt 18 to ensure that the pipe remains stable during the transportation process. The conveyor belt 18 is responsible for transporting the pipe efficiently.

[0030] When the pipe falls onto the surface of the conveyor belt 18, in order to prevent the pipe from causing potential damage to the motor 8, the system is equipped with a buffer mechanism inside the conveyor belt 18. The buffer mechanism contacts the conveyor belt 18 through the roller 29 on the top of the buffer plate 27, ensuring that the buffer plate 27 will not interfere with the normal operation of the conveyor belt 18. When the pipe falls onto the conveyor belt 18, it will exert force on the buffer plate 27, causing the buffer plate 27 to move accordingly, thereby effectively buffering the force through the compression damper 28.

[0031] Meanwhile, during its movement, the buffer plate 27 changes the direction of force through transmission rod 10 and transmission rod 2 33, thereby pushing the sliding block 31 to slide smoothly along the slide rod 30. The relative movement of the two symmetrical sliding blocks 31 effectively cancels out the force, and the spring 32 further buffers this process, ensuring the stable and safe operation of the entire system.

[0032] Working principle: When this push-pull maintenance operating system is running, the winch 2 drives the steel cable 5 to pull the submersible pump. Simultaneously, the guide wheel 3 and guide roller 4 guide the steel cable 5. As the submersible pump is pulled up, it carries the connected pipeline, which is fixed to the fixed plate 23 and secured by the fixed frame 24. Bolts 25 tighten and secure the fixed frame 24 and the fixed plate 23, thus fixing the pipeline. The rollers 21 on both sides of the connecting shaft 22 then roll on the roller frame 20. The pipe can be pulled up, and the infrared sensor 19 detects the distance the steel cable 5 is retracted, allowing control of the pipe to achieve a specific pulling distance. This facilitates the disassembly of each pipe section. After the pipe stops moving, the motor 8 drives the lead screw 9, which in turn moves the connecting rod 11. The connecting rod 11 then drives the wedge-shaped support rod 13 to slide along the slide rail 12 and extend to the bottom of the pipe to scoop it up. The cylinder 15 then controls the movable gripper 17 to rotate, thereby clamping and fixing the pipe, allowing for further processing. After the pipe is disassembled, the movable gripper 17 is rotated and opened, allowing the pipe to roll onto the conveyor belt 18 via the inclined surface of the wedge-shaped support rod 13. The side support frames 7 on both sides of the conveyor belt 18 prevent the pipe from rolling off the surface of the conveyor belt 18, allowing the conveyor belt 18 to transport the pipe. To prevent damage to the motor 8 when the pipe falls onto the surface of the conveyor belt 18, a buffer mechanism is installed inside the conveyor belt 18. The buffer mechanism contacts the conveyor belt 18 via the roller 29 at the top of the buffer plate 27 to prevent the buffer plate 27 from interfering with the operation of the conveyor belt 18. When the pipe falls onto the conveyor belt 18, it will exert force on the buffer plate 27, causing the buffer plate 27 to move. This force is buffered by the compression damper 28. At the same time, when the buffer plate 27 moves, it will change the direction of the force through the transmission rod 10 and the transmission rod 23, thereby pushing the sliding block 31 to slide along the sliding rod 30. The relative movement of the symmetrical sliding blocks 31 on both sides can cancel out the force, and the spring 32 buffers the process.
