Description

Technical Field

[0001] This utility model relates to the field of water conservancy machinery technology, and in particular to a segmented disassembly and reassembly push-pull maintenance operation device for raising and lowering submersible pumps. Background Technology

[0002] Submersible pumps, as key equipment for underwater operations, are widely used in various fields such as municipal drainage, farmland irrigation, mine drainage, and sewage treatment. Their stable operation is directly related to the normal operation of production and daily life. During long-term use, submersible pumps are subject to the influence of complex underwater environments (such as siltation, water corrosion, and debris entanglement), and equipment failures occur from time to time. Therefore, regular inspection and maintenance are necessary to ensure their efficient operation.

[0003] In the maintenance of submersible pumps, raising and lowering operations are one of the core steps, and the push-pull maintenance operation device is the key equipment to realize this process. The existing push-pull maintenance operation device mainly realizes the raising and lowering control of the submersible pump through a mechanical transmission structure. Although it can meet the basic raising and lowering functions, it has significant defects in actual operation: when the submersible pump is raised or lowered to a specified distance, the device lacks an effective prompting mechanism. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a segmented, detachable push-pull maintenance operation device for raising and lowering submersible pumps, aiming to improve the problem that existing push-pull maintenance operation devices lack prompts after raising or lowering to a specified distance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a segmented, detachable push-pull maintenance operating device for raising and lowering a submersible pump, comprising a base plate for supporting the push-pull maintenance operating device; a winch for providing power to the push-pull maintenance operating device; a limiting mechanism for limiting the raising or lowering distance; and a support mechanism for supporting the movement of a trolley. The limiting mechanism includes a limiting block, which is rotatably connected to a rotating disk. The rotating disk has an arc-shaped groove inside, and the limiting block is slidably connected to a limiting device inside. The positioning plate has a limiting post fixedly connected to its outer wall. The outer wall of the limiting post is slidably connected to the inside of an arc-shaped groove. A gear is fixedly connected to the outer wall of the rotating disk. A rack is slidably connected inside the limiting block. A pull rod is fixedly connected to the top of the rack. The rack meshes with the gear. A rotary spring is provided inside the limiting block. One side of the rotary spring is fixedly connected to the inside of the limiting block, and the other side of the rotary spring is fixedly connected to the outer wall of the gear. The winch can wind up the steel cable. A limiting ball is fixedly connected to the outer wall of the steel cable.

[0006] Furthermore, the support mechanism includes a track, which can be spliced ​​together in multiple segments.

[0007] Furthermore, a fixing plate is fixedly connected to the bottom of the track, which can fix the track in place.

[0008] Furthermore, a mounting plate is fixedly connected to the outer wall of the track, and the mounting plate can be used to splice the track or connect it to other components.

[0009] Furthermore, the support mechanism also includes a left connecting block, on one side of which a support wheel is rotatably connected.

[0010] Furthermore, a right connecting block is rotatably connected to one side of the support wheel, and a second mounting plate is fixedly connected to the outer wall of the right connecting block.

[0011] Furthermore, a mounting plate three is fixedly connected to the outer wall of the right connecting block, and both the mounting plate two and the mounting plate three can be connected to the mounting plate one.

[0012] Furthermore, a guide roller is rotatably connected to one side of the support wheel.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, a limiting ball is installed on the steel cable. When the steel cable is retracted or released, the steel cable will pass through the limiting block. The limiting plate inside the limiting block can allow the steel cable to pass through while blocking the limiting ball. Thus, the cable can be limited after being stretched or released a certain distance, which improves the convenience of positioning when disassembling the pipe.

[0015] 2. In this utility model, the track can be spliced ​​by mounting plate one. When encountering a corner, mounting plate one can be connected to mounting plate two, so that the left connecting block and the right connecting block are located at the corner. Thus, the rotation of the left connecting block and the right connecting block adapts to the angle at the corner. At the same time, the support wheel can continue to support the movement of the trolley, which improves the convenience of installing the trolley's moving track. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1-4 This utility model provides an embodiment of a segmented, detachable push-pull maintenance operating device for raising and lowering a submersible pump, comprising: a base plate 1 for supporting the push-pull maintenance operating device; a winch 2 for providing power to the push-pull maintenance operating device; a limiting mechanism for limiting the raising or lowering distance; and a support mechanism for supporting the movement of a trolley. The limiting mechanism includes a limiting block 3, which is rotatably connected to a rotating disk 8. The rotating disk 8 has an arc-shaped groove 9 inside, and a limiting plate 11 is slidably connected inside the limiting block 3. 1. A limiting post 10 is fixedly connected to the outer wall. The outer wall of the limiting post 10 is slidably connected to the inside of the arc groove 9. A gear 12 is fixedly connected to the outer wall of the rotating disk 8. A rack 13 is slidably connected inside the limiting block 3. A pull rod 7 is fixedly connected to the top of the rack 13. The rack 13 meshes with the gear 12. A rotating spring 14 is provided inside the limiting block 3. One side of the rotating spring 14 is fixedly connected to the inside of the limiting block 3. The other side of the rotating spring 14 is fixedly connected to the outer wall of the gear 12. The winch 2 can wind up the steel cable 4. A limiting ball 5 is fixedly connected to the outer wall of the steel cable 4.

[0024] Specifically, the push-pull maintenance operation device has a precise mechanical structure that can control the winding and unwinding of the steel cable 4 through the winch 2. A series of limit balls 5 are specially set on the steel cable 4. These limit balls 5 are arranged according to the specific distance required for actual operation. When the steel cable 4 is being wound or unwound, it will pass smoothly through the limit block 3. When the steel cable 4 is in the unwound state, due to the elastic force provided by the rotating spring 14, the limit plate 11 will remain in the retracted state. At this time, the limit plate 11 inside the limit block 3 allows the steel cable 4 to pass freely, but will effectively block the limit balls 5, thereby ensuring that the steel cable 4 can achieve accurate limiting function after being stretched or unwound to a specific distance.

[0025] After the pipeline dismantling or splicing work is completed, the operator can pull the lever 7, which will cause the rack 13 to slide smoothly. Subsequently, the rack 13 will drive the gear 12 to rotate. Under the action of overcoming the elastic force of the rotating spring 14, the gear 12 will drive the rotating disk 8 to rotate. As the rotating disk 8 rotates, the arc-shaped groove 9 inside it will also move. The inner wall of the arc-shaped groove 9 will push the limiting post 10, which will cause the guide roller 19 to drive the limiting plate 11 to slide, and finally open the limiting plate 11, allowing the limiting ball 5 to pass smoothly.

[0026] In the overall structure of this device, the track 6 is flexibly spliced ​​through mounting plates 16 and firmly fixed to the ground by fixing plates 15, providing a stable track 6 for the trolley's operation. When the track 6 encounters a corner, mounting plates 21 and 22, installed on the outer walls of the left connecting block 17 and the right connecting block 18, can reliably connect to mounting plates 16 on both sides of the track 6. Through the flexible rotation of the support wheels 20, the device can adapt to various corners encountered by the track 6, while the support wheels 20 also provide solid support for the trolley. In addition, guide rollers 19 can be connected to the support wheels 20, providing precise guidance for the steel cable 4.

[0027] Working principle: This push-pull maintenance device allows the winch 2 to retract and extend the steel cable 4. Limiting balls 5 are installed on the steel cable 4 at the required distances. During retraction and extension, the steel cable 4 passes through the limiting block 3. In the lowered state, the force of the rotating spring 14 keeps the limiting plate 11 in a retracted state. The limiting plate 11 inside the limiting block 3 allows the steel cable 4 to pass through while blocking the limiting balls 5, thus limiting the cable 4 after it has been stretched or lowered a specific distance. After the pipe is dismantled or reassembled, the pull rod 7 can be pulled, causing the pull rod 7 to drive the rack 13 to slide. The rack 13 then drives the gear 12 to rotate, which in turn overcomes the force of the rotating spring 14 and drives the rotating disk 8 to rotate. The arc-shaped groove 9 inside the rotating disk 8... As it moves, the inner wall of the arc groove 9 pushes the limiting post 10, causing the guide roller 19 to slide along the limiting plate 11, thus opening the limiting plate 11 and allowing the limiting ball 5 to pass through. In this device, the track 6 can be spliced ​​together by the mounting plate 16 and fixed to the ground by the fixing plate 15, thus providing the track 6 for the trolley to run on. When the track 6 encounters a corner, the mounting plates 21 and 22 on the outer walls of the left connecting block 17 and the right connecting block 18 can be connected to the mounting plates 16 on both sides of the track 6, respectively. Thus, by rotating the support wheel 20, it can adapt to the corner encountered by the track 6, and the support wheel 20 can support the trolley. At the same time, the guide roller 19 can be connected to the support wheel 20, so that the guide roller 19 can provide guidance for the steel cable 4.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
