Description

Technical Field

[0001] This utility model relates to the field of water conservancy machinery technology, and in particular to a special push-pull maintenance trolley for segmented pipe disassembly of submersible pumps in high-level water tanks. Background Technology

[0002] As an important water supply facility, elevated water tanks undertake critical tasks such as providing domestic water, industrial water, and emergency water supply within the region. Submersible pumps are the core power equipment for the transport and circulation of water in elevated water tanks. Because elevated water tanks are mostly built at higher elevations, submersible pumps are in a specific installation environment for extended periods. Affected by factors such as water quality, water pressure, and operating time, equipment components are prone to wear, aging, and blockage. Therefore, regular inspection and maintenance of submersible pumps is an important measure to ensure the stability and safety of the water supply from elevated water tanks.

[0003] In the maintenance of submersible pumps in elevated water tanks, due to the special installation location and complex pipeline connections, it is usually necessary to use a push-pull maintenance trolley to complete operations such as disassembly, movement, and installation of pipelines. Existing push-pull maintenance trolleys mainly consist of a frame, wheels, and a push-pull mechanism, with multiple trolleys working together to support and move different sections of pipeline. However, in actual maintenance, existing trolleys have a prominent problem: they cannot maintain a stable state between two trolleys. During pipeline connection, the pipeline supported by the two trolleys is prone to relative displacement, tilting, or shaking due to uneven force or slight external interference, resulting in inaccurate alignment of the pipeline joints and increasing installation difficulty. Operators often need to repeatedly adjust the trolley position and pipeline posture, which not only prolongs maintenance time but may also cause wear on the pipeline joints due to repeated adjustments, affecting subsequent sealing performance. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a push-pull maintenance trolley for segmented pipe disassembly of submersible pumps in high-level water tanks. It aims to improve the problem that the existing push-pull maintenance trolley cannot maintain the stability between the two trolleys, which leads to the inconvenience of installing the pipes fixed between the two trolleys.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a special push-pull maintenance trolley for segmented pipe disassembly of submersible pumps in high-level water tanks, comprising a support rod as the main support body of the trolley; rollers for supporting the movement of the trolley; a connecting mechanism for ensuring stability between two pipe sections; and a fixing mechanism for fixing the pipes. The connecting mechanism includes a connecting rod and a connecting block, the connecting block fitting against the connecting rod, a slot being formed inside the connecting block, a positive and negative threaded rod being rotatably connected inside the connecting rod, a handle being fixedly connected to one end of the positive and negative threaded rod, a slider being slidably connected inside the connecting rod, the slider being threadedly connected to the positive and negative threaded rod, and a rectangular locking block being fixedly connected to the outer wall of the slider, the rectangular locking block being able to slide out of the connecting rod and engage in the slot.

[0006] Furthermore, the fixing mechanism includes a fixing ring, one side of which is rotatably connected to the top of the support rod.

[0007] Furthermore, a fixing plate is slidably connected inside the support rod, and a second slot is provided inside the fixing ring.

[0008] Furthermore, a wedge-shaped locking block is fixedly connected to the top of the fixing plate, and the wedge-shaped locking block can be locked into the inside of the second locking slot.

[0009] Furthermore, a sliding column is fixedly connected to the bottom of the fixing plate, and the sliding column is slidably connected inside the support rod.

[0010] Furthermore, a sliding rod is fixedly connected inside the support rod, and the sliding rod is slidably connected to the sliding column.

[0011] Furthermore, a spring is sleeved on the outer wall of the slide rod, and a limit post is fixedly connected to the outer wall of the slide column.

[0012] Furthermore, a pressing block is slidably connected inside the support rod, and a sliding plate is fixedly connected to the bottom of the pressing block. A limiting groove is formed inside the sliding plate, and a limiting post is slidably connected inside the limiting groove.

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

[0014] 1. In this utility model, the connecting rod is connected to the connecting block, and then driven by the handle, thereby controlling the forward and reverse threaded rods to drive the slider, so that the rectangular card block is inserted into the card slot opened inside the connecting block, thereby connecting the two trolleys. This solves the problem of not being able to ensure the stability between the two trolleys and improves the stability of pipeline installation and disassembly.

[0015] 2. In this utility model, the rotation of the fixing ring can lock the pipe, and the elasticity of the spring can cause the wedge-shaped block to slide due to the inner wall of the fixing ring, reset and lock into the second slot, thereby fixing the other side of the fixing ring to the support rod, thus fixing the pipe and improving the stability and convenience of pipe fixing.

Detailed Implementation

[0023] 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.

[0024] Reference Figure 1-5This utility model provides an embodiment of a special push-pull maintenance trolley for segmented pipe disassembly of submersible pumps in high-level water tanks, comprising: a support rod 1, serving as the main support body of the trolley; rollers 4, for moving support of the trolley; a connecting mechanism, for ensuring stability between two pipe sections; and a fixing mechanism, for fixing the pipes. The connecting mechanism includes a connecting rod 3 and a connecting block 6, the connecting block 6 being in contact with the connecting rod 3, a slot 7 being provided inside the connecting block 6, a positive and negative threaded rod 11 being rotatably connected inside the connecting rod 3, a handle 10 being fixedly connected to one end of the positive and negative threaded rod 11, a slider 9 being slidably connected inside the connecting rod 3, the slider 9 being threadedly connected to the positive and negative threaded rod 11, and a rectangular locking block 8 being fixedly connected to the outer wall of the slider 9, the rectangular locking block 8 being able to slide out of the connecting rod 3 and engage in the slot 7.

[0025] Specifically, the pipe can be placed stably above the support rod 1. Then, by manually rotating one side of the fixing ring 2, the fixing ring 2 can be firmly locked onto the pipe supported on the support rod 1. When the other side of the fixing ring 2 is tightly pressed against the top wall of the support rod 1, the inner wall of the fixing ring 2 will apply pressure to the wedge-shaped locking block 13. This pressure allows the wedge-shaped locking block 13 to be inserted into the internal space of the fixing ring 2. At the same time, the wedge-shaped locking block 13, through the connection of the fixing plate 14, drives the sliding column 15 to slide smoothly and moderately compresses the spring 17. With the help of the elastic force of the spring 17, the wedge-shaped locking block 13 can be inserted into the preset locking groove 12 inside the support rod 1 and complete the reset action, thereby ensuring that the fixing ring 2 is firmly fixed on the support rod 1.

[0026] When it is necessary to open the fixing ring 2, the pressing block 5 can be pressed to push the sliding plate 18 to move. The limiting groove 19 inside the sliding plate 18 will also be displaced. The inner wall of the limiting groove 19 will push the limiting post 20, which in turn will cause the limiting post 20 to drive the sliding post 15 to slide. This series of actions can effectively control the wedge-shaped block 13 to slide out from the slot 12, thereby opening the fixing ring 2.

[0027] During the pipe docking installation process of fixing two trolleys, the two trolleys can be connected by connecting rod 3. Connecting rod 3 will fit tightly with connecting block 6 on the outer wall of support rod 1. Then, the positive and negative threaded rod 11 is rotated by operating handle 10. The rotation of positive and negative threaded rod 11 will drive the sliders 9 on both sides to move synchronously and relative, thereby driving the rectangular locking block 8 to lock into the locking groove 7 opened on the outer wall of connecting block 6, thus realizing the firm fixation of connecting rod 3 and support rod 1. Finally, it is ensured that the two trolleys can be firmly fixed together, and the pipe docking installation work is successfully completed.

[0028] Working principle: The pipe can be placed on the support rod 1. Rotation of one side of the fixing ring 2 locks the pipe on the support rod 1. When the other side of the fixing ring 2 is against the top wall of the support rod 1, the inner wall of the fixing ring 2 presses against the wedge-shaped locking block 13, allowing it to insert into the fixing ring 2. Simultaneously, the wedge-shaped locking block 13 slides through the fixing plate 14, driving the sliding column 15 to compress the spring 17. The force of the spring 17 then causes the wedge-shaped locking block 13 to insert into the slot 12 inside the support rod 1 and reset, thus fixing the fixing ring 2 onto the support rod 1. When the fixing ring 2 is open, pressing the pressing block 5 pushes the sliding plate 18. The limiting groove 19 inside the skateboard 18 will move accordingly, thereby pushing the limiting post 20 by the inner wall of the limiting groove 19, causing the limiting post 20 to drive the sliding post 15 to slide. This will control the wedge-shaped block 13 to slide out of the slot 12, thereby opening the fixing ring 2. When the pipes of the two trolleys are connected for installation, the two trolleys can be connected by the connecting rod 3. The connecting rod 3 will fit against the connecting block 6 on the outer wall of the support rod 1. Then, the handle 10 controls the positive and negative threaded rods 11 to rotate. The positive and negative threaded rods 11 will drive the sliders 9 on both sides to move synchronously relative to each other, thereby causing the rectangular block 8 to be inserted into the slot 7 on the outer wall of the connecting block 6, thus fixing the connecting rod 3 and the support rod 1, thereby fixing the two trolleys.

[0029] 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.
