Description

Technical Field

[0001] This invention relates to the field of hydraulic machinery technology, specifically to a segmented pipe-disassembly type push-pull maintenance trolley system for submersible pumps in elevated water tanks. Background Technology

[0002] In water conservancy projects, municipal water supply, and industrial circulating water systems, elevated water tanks serve as crucial water storage and supply facilities. The stable operation of the submersible pumps within these tanks directly impacts the reliability of the water supply system. Submersible pumps operate continuously underwater or in humid environments, making them prone to issues such as impeller wear, motor failure, and aging seals, requiring regular maintenance or replacement. Due to the significant depth and height differences typically found in elevated water tanks, the installation and maintenance of submersible pumps have always been a technical challenge within the industry.

[0003] Existing push-pull maintenance trolley systems lack dedicated integrated solutions for pipeline handling. Pipeline disassembly and installation rely entirely on manual labor or additional auxiliary equipment such as cranes and jacks. Specifically, after the submersible pump is moved to the maintenance location, operators must first manually remove the bolts at the pipe flange connection. After the pipe is separated from the submersible pump, it must be manually lifted or moved to a temporary storage area by a crane. During installation, the above process must be repeated in reverse: the pipe is first hoisted to the docking position, then the pipe's posture is manually adjusted to achieve precise docking with the submersible pump, and finally the bolts are tightened. Summary of the Invention

[0017] Beneficial effects

[0019] 1. In this push-pull maintenance trolley system, the pipe can be fixed by the clamping mechanism, then disassembled.

[0026] 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.

[0027] Please see Figure 1-4 A segmented pipe-disassembly push-pull maintenance trolley system for submersible pumps in high-level water tanks includes: a base 1 for overall support of the push-pull maintenance trolley system; a trolley mechanism for supporting pipe movement; a slide rail 5 for supporting the movement of the trolley mechanism, installed on one side of the base 1; a pick-and-place mechanism for picking up and placing pipes, including a clamping mechanism and a moving mechanism, installed on the top of the slide rail 5; and a limiting mechanism for limiting the pipe movement distance, installed inside the slide rail 5. The clamping mechanism includes a fixed frame 7, a motor frame 19 fixedly connected to the outer wall of the fixed frame 7, a second motor 18 fixedly connected to the outer wall of the motor frame 19, a drive gear 20 rotatably connected inside the fixed frame 7, the second motor 18 driving the drive gear 20 to rotate, and a gripper 23 and a gripper 17 rotatably connected inside the fixed frame 7. A half gear 22 is fixedly connected to one side of the second half gear 23, and the two half gears 22 mesh with each other. A second drive gear 21 is fixedly connected to the top of one half gear 22, and the second drive gear 21 meshes with the first drive gear 20. The moving mechanism includes a support frame 6, a fixed rod 8 is fixedly connected to the top of the support frame 6, a cylinder 9 is fixedly connected to the top of the support frame 6, a slide rod 11 is slidably connected inside the fixed rod 8, the cylinder 9 is used to drive the slide rod 11 to slide, a sliding ring 10 is slidably connected to the outer wall of the fixed rod 8, a connecting frame 12 is fixedly connected to the bottom of the sliding ring 10, one side of the connecting frame 12 is fixedly connected to the bottom of the slide rod 11, and a first motor 13 is fixedly connected to the bottom of the connecting frame 12. The first motor 13 can drive the storage tray 14 to rotate, and a sling 15 is fixedly connected to the outer wall of the storage tray 14. The sling 15 is connected to the clamping mechanism through a pulley 16.

[0028] In this embodiment, during the operation of the device, the steel cable 3 can be driven by the winch 2 to move, thereby enabling the steel cable 3 to effectively drive the submersible pump to perform the winding and unwinding operation. During this process, the guide roller 34 and the guide wheel 32 work together to ensure that the movement direction of the steel cable 3 is accurate. At the same time, the pipeline will also move accordingly. In order to ensure the stability and safety of the pipeline during the movement, the pipeline is firmly fixed to the fixing plate 27 by the fixing ring 26 and further reinforced by the bolts 28.

[0029] After the pipe is fixed and secure, it can move smoothly on the slide rail 5 with the help of rollers 33. As the pipe moves, the axle 4 at the bottom of the fixed plate 27 will gradually contact the baffle 30, and in the process, the pressure sensor 31 will be triggered. After the pressure sensor 31 is triggered, it will send a signal to the control system, thereby controlling the motor 18 to start and drive.

[0030] After the second motor 18 starts, it will drive the first drive gear 20 to rotate. The rotation of the first drive gear 20 will further drive the second drive gear 21 to rotate synchronously. The rotation of the second drive gear 21 can effectively drive the second gripper 23 to rotate accordingly. At the same time, due to the connection of the half gear 22, the second gripper 23 and the first gripper 17 can achieve synchronous relative movement, thereby providing stable and powerful clamping for the pipeline.

[0031] When the pipeline needs to be removed, the sliding rod 11 can be moved by the driving action of the cylinder 9. The sliding of the sliding rod 11 will drive the bottom connecting frame 12 to move synchronously. At the same time, the motor 13 will also start, driving the storage tray 14 to rotate and orderly retract the sling 15. Through this series of operations, the fixing frame 7 can be controlled to rise gradually, thereby lifting the pipeline smoothly.

[0032] After the pipe is lifted, the connecting frame 12 will continue to move the storage tray 14 horizontally, safely moving the pipe to the adjacent storage location. After the pipe is dismantled, the motor 24 will start, driving the limiting roller 25 to rotate. The rotation of the limiting roller 25 will remove the obstruction effect of the baffle 30 from the axle 4, thus creating conditions for the movement and dismantling of the next section of pipe. At this time, the winch 2 can continue to drive the steel cable 3, allowing the next section of pipe to move smoothly to that location for a new round of dismantling operations.

[0033] Working principle: When the equipment is running, the winch 2 drives the steel cable 3, which in turn drives the submersible pump to move in and out. Guide rollers 34 and guide wheels 32 guide the pump, causing the pipeline to move accordingly. The pipeline is fixed to the fixed plate 27 by a fixing ring 26 and reinforced by bolts 28. The pipeline can then move on the slide rail 5 using rollers 33. As the pipeline moves, the axle 4 at the bottom of the fixed plate 27 is blocked by the baffle 30, triggering the pressure sensor 31. This triggers the motor 18, which drives the drive gear 20, which in turn drives the drive gear 21. The drive gear 21 then drives the gripper 23 to rotate. Due to the connection of the half gear 22, the second clamp 23 and the first clamp 17 can move synchronously relative to each other, thereby clamping the pipe. After the pipe is removed, the cylinder 9 can drive the slide rod 11 to slide, and the slide rod 11 will drive the bottom connecting frame 12 to move synchronously. At the same time, the motor 13 can drive the storage tray 14 to rotate, and the hoisting cable 15 can be retracted. Then the fixed frame 7 can be controlled to rise, thereby lifting the pipe. The connecting frame 12 drives the storage tray 14 to move horizontally, thereby moving the pipe to the side for storage. After the pipe is removed, the motor 3 24 will drive the limiting roller 25 to rotate, so that the axle 4 will be freed from the obstruction of the baffle 30. Then the winch 2 can continue to drive the steel cable 3, so that the next section of pipe can be moved to the same place for removal.
