Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering construction technology, and in particular to a support structure for the construction of water conservancy pumping stations. Background Technology

[0002] Pumping stations are key water conservancy engineering facilities that utilize pumps and other power machinery to regulate water resources. They are widely used in flood control, drainage, irrigation, and water supply, and are of great significance to the stable development of society and the economy. The supporting structure, as a combination of components providing stable load-bearing capacity and maintaining its shape, is an indispensable safety barrier during pumping station construction. Because pumping stations are often built in river channels and tidal flats with complex hydrogeological conditions, construction requires the excavation of deep foundation pits. The supporting structure can stabilize the pit walls through retaining walls and water-stopping mechanisms, preventing collapse. Simultaneously, during concrete pouring, it can fix the formwork, withstand lateral pressure, and ensure the accuracy of component forming. It can also control the deformation of the foundation pit, reducing disturbance to the surrounding environment. Therefore, it is a core facility for ensuring construction safety, quality, and progress.

[0003] Existing support structures for water conservancy pumping station construction have significant drawbacks: inconvenient angle adjustment makes them difficult to adapt to complex scenarios commonly encountered in pumping station construction, such as inclined pit walls and sloping installation surfaces, resulting in insufficient support fit; and a lack of flexibility in height adjustment makes it impossible to quickly adjust the support height according to different construction elevations, which affects construction efficiency and reduces stability due to the mismatch between support dimensions and actual needs, thus posing potential safety hazards. Therefore, a new support structure for water conservancy pumping station construction is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a support structure for the construction of water conservancy pumping stations, aiming to improve the problem of inconvenient angle and height adjustment of the support structure for the construction of water conservancy pumping stations in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a support structure for the construction of a water conservancy pumping station, including a base, a fixed frame rotatably connected to the top of the base, a support platform fixedly connected to the top of the fixed frame, a rotating component provided at the top of the base, and a height component provided at the bottom of the base;

[0006] The rotating assembly includes a fixed box, a handle is rotatably connected to the outside of the fixed box, a worm gear is fixedly connected to the outside of the handle, a worm wheel is rotatably connected to the top of the base, a rotating rod one is fixedly connected to the outside of the worm wheel, a rotating rod two is fixedly connected to the outside of the rotating rod one, a fixed rod is rotatably connected to the outside of the rotating rod two, two rotating plates are rotatably connected to the outside of the fixed rod, and a base is rotatably connected between the two rotating plates.

[0007] As a further description of the above technical solution:

[0008] The height component includes two outer rods, each with multiple fixing slots on its outer side. An inner rod is slidably connected to the outer rod, and an installation slot is provided inside the inner rod. A connecting rod is slidably connected inside the installation slot. A spring is fixedly connected to one side of the connecting rod, and a limit rod is fixedly connected to the other side of the connecting rod.

[0010] The worm gear and the worm are engaged.

[0011] As a further description of the above technical solution:

[0012] The limiting rod is slidably connected inside the mounting groove, and the limiting rod is slidably connected inside the fixing groove.

[0013] As a further description of the above technical solution:

[0014] The side of the spring away from the limiting rod is fixedly connected inside the mounting groove.

[0015] As a further description of the above technical solution:

[0016] The inner rod is fixedly connected to the bottom of the base.

[0017] As a further description of the above technical solution:

[0019] As a further description of the above technical solution:

[0020] The rotating rod is rotatably connected to the top of the base, and the fixed box is fixedly connected to the top of the base.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, rotating the handle drives the worm gear to rotate synchronously. The worm gear, through meshing with the worm wheel, drives the worm wheel to rotate, which in turn drives the first rotating rod to rotate. The first rotating rod then drives the second rotating rod to rotate. The second rotating rod drives the rotating plate to rotate through the fixed rod. The rotating plate causes the base to rotate, and the base drives the support platform to move synchronously. Because one end of the support platform is fixed to the base by the fixed frame, it can rotate around the axis with the fixed frame as the center, realizing flexible adjustment of the support platform angle, adapting to various complex construction scenarios, and ensuring the stability and applicability of the support.

[0023] 2. In this utility model, by pressing the limiting rod, the connecting rod is moved and the spring is compressed, disengaging from the current fixed groove, and the inner rod is in a free state; pulling the base moves the inner rod to achieve initial height adjustment; when the desired height is reached, the spring rebounds, and the connecting rod drives the limiting rod to slide into another fixed groove, fixing the outer rod and the inner rod, thereby completing the height adjustment of the base and support platform. This achieves flexible height adjustment of the support platform, adapting to different construction elevations, and is easy to operate, meeting diverse support needs. Attached Figure Description

[0030] 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.

[0031] Reference Figures 1-4This utility model provides an embodiment of a support structure for the construction of a water conservancy pumping station, including a base 2, a fixed frame 3 rotatably connected to the top of the base 2, a support platform 1 fixedly connected to the top of the fixed frame 3, a rotating component on the top of the base 2, and a height component at the bottom of the base 2. The base 2 serves as the foundation carrier of the overall structure, connecting the rotating component and the height component, providing a stable installation reference for each component, and enhancing the overall stability of the support structure in complex construction environments. The fixed frame 3 connects the support platform 1 and the base 2, providing a fulcrum for the rotation of the support platform 1, ensuring that the support platform 1 can be smoothly adjusted around the fixed frame 3 as the center, and avoiding deviation during angle adjustment. The support platform 1 serves as a direct... The load-bearing component provides a stable contact surface for the templates, equipment, etc. to be supported. With the rotating component, it can be tilted at multiple angles to meet the support needs of inclined pipes and irregular components in pump station construction, ensuring the support fit. The rotating component allows the support platform 1 to flexibly adjust the angle with the fixed frame 3 as the center, adapting to complex scenarios such as inclined pit walls and sloping installation surfaces in pump station construction, improving the support fit and ease of operation. The worm gear 6 and worm wheel 7 structure have a self-locking function to ensure the angle is stable and does not rebound. The height component can quickly adjust the support height to adapt to different construction elevations. Operation does not require tools. The spring 16 ensures a firm lock and is not easy to loosen in a vibration environment, improving the efficiency and stability of height adjustment.

[0032] The rotating assembly includes a fixed box 4, a handle 5 rotatably connected to the outside of the fixed box 4, a worm gear 6 fixedly connected to the outside of the handle 5, a worm wheel 7 rotatably connected to the top of the base 2, a rotating rod 8 fixedly connected to the outside of the worm wheel 7, a rotating rod 9 fixedly connected to the outside of the rotating rod 8, a fixed rod 19 rotatably connected to the outside of the rotating rod 9, two rotating plates 10 rotatably connected to the outside of the fixed rod 19, and a base 11 rotatably connected between the two rotating plates 10. The fixed box 4 protects the internal rotating assembly, including the worm gear 6, isolating it from dust and mud in the construction environment, reducing component wear, extending the service life of the rotating assembly, and ensuring transmission stability. The handle 5 provides a convenient point of force application, making it easy for operators to rotate the worm gear 6, saving effort and making it easy to control the rotation speed, improving the ease of angle adjustment. The worm gear 6 meshes with the worm wheel 7 to achieve transmission, utilizing its helical transmission characteristics to convert the rotational motion of the handle 5 into the rotation of the worm wheel 7, precisely controlling the angle adjustment. The worm gear 7 and worm 6 mesh to transmit power, driving the rotating rod 8 to rotate. The number of teeth of the rotating rod 7 and worm 6 are matched to form a suitable transmission ratio, improving the accuracy of angle adjustment and ensuring that the angle of the support platform 1 can be precisely controlled. The rotating rod 8 transmits the rotational power of the worm gear 7. The rotating rod 9 is linked to the rotating plate 10 through the fixed rod 19, transmitting the rotational power to the support platform 1. Its length and connection method are adapted to the rotation trajectory of the support platform 1, ensuring that the angle adjustment process is smooth and without jamming. The fixed rod 19 connects the rotating rod 9 and the rotating plate 10 to form a stable force transmission structure, enhancing the overall rigidity of the rotating component, avoiding component deformation during angle adjustment, and ensuring the stability of force transmission. The rotating plate 10 expands the force transmission area, making the support platform 1 bear force evenly, avoiding platform deformation due to excessive local force, and ensuring structural stability during angle adjustment. The base 11 is used to transmit force to the support platform 1.

[0033] The height adjustment component includes two outer rods 12. Multiple fixing slots 13 are formed on the outer sides of the outer rods 12. An inner rod 14 is slidably connected inside the outer rods 12. An installation slot 15 is formed inside the inner rod 14, and a connecting rod 17 is slidably connected inside the installation slot 15. A spring 16 is fixedly connected to one side of the connecting rod 17, and a limit rod 18 is fixedly connected to the other side of the connecting rod 17. The outer rods 12 serve as the outer carrier for height adjustment, slidingly engaging with the inner rods 14 to provide guidance for height adjustment. The fixing slots 13 provide multiple locking positions for the limit rod 18, allowing for different height fixation through engagement with the limit rod 18. The spacing design adapts to common elevation requirements in pump station construction, improving the flexibility of height adjustment. The inner rod 14 achieves height adjustment through sliding, and its clearance fit with the outer rods 12 ensures smooth sliding. The mounting groove 15 enhances the vertical load-bearing capacity of the overall structure, provides installation space for components such as the spring 16, protects internal components from external collisions, and guides the limiting rod 18 to move in a straight line, ensuring that it is accurately engaged in the fixing groove 13. The connecting rod 17 transmits the elastic force of the spring 16, ensuring that the elastic force is evenly applied to the limiting rod 18, so that the limiting rod 18 and the fixing groove 13 fit tightly together, improving the locking effect. The spring 16 provides continuous elastic force to the limiting rod 18, making it stably engaged in the fixing groove 13, achieving reliable locking after height adjustment, preventing the limiting rod 18 from disengaging due to vibration, and ensuring the stability of height fixation. The limiting rod 18 achieves height locking by engaging different fixing grooves 13. The structure is simple, and the locking can be released by pressing, making it convenient to operate and adapting to the needs of rapid height adjustment during pump station construction.

[0034] The worm gear 7 and worm 6 mesh to achieve precise power transmission. The self-locking characteristics of the worm gear 7 and worm 6 ensure that the support platform 1 does not spring back after the angle is adjusted, thus improving the reliability of the angle locking and meeting the angle stability requirements in pump station construction.

[0035] The limiting rod 18 is slidably connected inside the mounting groove 15 and the fixing groove 13. The limiting rod 18 slides in the mounting groove 15 to ensure movement guidance and is locked into the fixing groove 13 to achieve height locking. The double sliding cooperation makes the height adjustment smooth and the locking firm, adapting to the different elevation support requirements of the pump station.

[0036] The side of the spring 16 away from the limiting rod 18 is fixedly connected inside the mounting groove 15. The spring 16 provides continuous elastic force to the limiting rod 18, ensuring that it fits tightly with the fixing groove 13 and is not easy to loosen even in a vibration environment, thus ensuring the long-term stability of the high lock.

[0037] The inner rod 14 is fixedly connected to the bottom of the base 2, so that the inner rod 14 can simultaneously drive the base 2 and the upper structure to rise and fall during height adjustment, ensuring the linkage of the overall structure, avoiding the separation of parts during adjustment, and improving the overall performance of height adjustment.

[0038] The base 11 is fixedly connected to the bottom of the support platform 1. The angle adjustment power is transmitted through the rotating plate 10 to ensure that the support platform 1 rotates synchronously with the rotating component, thereby ensuring the accurate transmission of angle adjustment and improving the angle adaptability of the support platform 1.

[0039] Rotating rod 8 is rotatably connected to the top of base 2, and fixed box 4 is fixedly connected to the top of base 2. Rotating rod 8 provides a movable fulcrum for angle adjustment, and fixed box 4 provides a stable mounting base for worm gear 6. The two work together to ensure smooth operation of the rotating component and improve the smoothness of angle adjustment.

[0040] Working principle:

[0041] In pump station construction scenarios, when faced with conditions requiring angle adjustment such as inclined pit walls, sloped equipment installation surfaces, and irregular component supports, the operating mechanism is as follows: Rotating the handle 5 drives the worm gear 6 to rotate synchronously. The worm gear 6, through meshing with the worm wheel 7, drives the worm wheel 7 to rotate. The worm wheel 7 then drives the rotating rod 8 to rotate, which in turn drives the rotating rod 9 to rotate. The rotating rod 9, through the connection of the fixed rod 19, drives the rotating plate 10 to rotate. The rotating plate 10 further causes the base 11 to rotate, which in turn drives the support platform 1 to move synchronously. Since one end of the support platform 1 is fixed to the base 2 via the fixed frame 3, the support platform 1 can rotate around the fixed frame 3 as the center, ultimately achieving angle adjustment of the support platform 1 to meet the support requirements of different construction scenarios.

[0042] When the support platform 1 cannot meet the support requirements of different construction elevations, the specific adjustment process is as follows: Press the limiting rod 18 simultaneously. The limiting rod 18 will drive the connecting rod 17 to move. The connecting rod 17 will then compress the spring 16, causing the limiting rod 18 to disengage from the current fixed groove 13. At this time, the inner rod 14 is in a free-moving state. By pulling the base 2, the base 2 will drive the inner rod 14 to move synchronously, thereby achieving the initial height adjustment. When the required height is reached, the spring 16 will automatically rebound, driving the connecting rod 17 to move. The connecting rod 17 will then cause the limiting rod 18 to move, allowing the limiting rod 18 to slide into another fixed groove 13, thereby achieving the relative fixation of the outer rod 12 and the inner rod 14. With the cooperation of the outer rod 12 and the inner rod 14, the height adjustment of the base 2 is completed, and finally the height adjustment of the support platform 1 is achieved to adapt to the support requirements of different construction elevations.

[0043] 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.
