Description

Technical Field

[0001] This utility model relates to the field of centrifugal pump installation technology, and in particular to an adjustable centrifugal pump mounting bracket. Background Technology

[0002] Centrifugal pumps, as core equipment in industrial fluid transport systems, are widely used in chemical, municipal, energy, and agricultural fields. Their installation stability directly affects system operating efficiency, equipment lifespan, and safe production. The support legs of the mounting bracket are key components that bear the weight of the pump body and maintain the installation reference.

[0003] Currently, in installation scenarios on flat ground, existing centrifugal pump mounting brackets mainly employ two types of support leg structures: fixed-height and single-leg independent adjustment. The traditional single-leg independent adjustment mode has significant operational drawbacks: operators must use tools such as levels and measuring tapes to adjust the height of each support leg individually, repeatedly checking the levelness of the bracket platform and the pump shaft installation height to gradually approach the preset installation benchmark. This adjustment method cannot achieve synchronized height adjustment of all support legs, easily causing height deviations, leading to bracket platform tilting, pump body stress imbalance, and ultimately shaft bending. Therefore, to better achieve synchronized adjustment of the centrifugal pump mounting bracket legs, and to promote technological advancement and enhance core technological competitiveness in the industry, this application proposes a new implementation scheme for centrifugal pump mounting brackets that differs from existing technologies. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing support legs cannot be adjusted synchronously, and to propose an adjustable centrifugal pump mounting bracket.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An adjustable centrifugal pump mounting bracket includes a mounting plate. A rotating column is rotatably connected to the bottom of the mounting plate. A first gear is keyed to the outer wall of the rotating column. A handle is fixedly connected to the bottom end of the rotating column. Rotating rods are rotatably connected to the four corners of the bottom of the mounting plate. A second gear is keyed to the top of the rotating rod. The second gear meshes with the first gear. A locking mechanism is provided on one side of the second gear. A threaded groove is provided on the outer wall of the rotating rod. A support cylinder is threaded to the bottom end of the rotating rod through the threaded groove.

[0006] Furthermore, a horizontal plate is fixedly connected between the two support cylinders, and a slider is fixedly connected to the top of the horizontal plate.

[0007] Furthermore, the mounting plate is provided with two sliding grooves, in which the slider slides.

[0008] Furthermore, two protective boxes are fixedly connected to the bottom of the mounting plate, and fixing plates are fixedly connected to both sides between the two protective boxes.

[0009] Furthermore, the locking mechanism includes multiple pawls, and rectangular slots are provided at both corners of the protective box. The pawls are rotatably connected in the rectangular slots via rotating shafts. The pawls mesh with the second gear, and return springs are sleeved at both ends of the rotating shafts of the pawls.

[0010] Furthermore, a first clearance groove and two second clearance grooves are provided between the top and bottom of the protective box, with the slider located in the first clearance groove and the rotating rod located in the second clearance groove.

[0011] Furthermore, a rubber block is adhered to the bottom end of the support cylinder.

[0012] The beneficial effects of this utility model are as follows: 1. By turning the handle, the rotating rod moves inside the support cylinder under the action of the meshing of the first and second gears, thereby driving the mounting plate to move and adjusting the height of multiple support legs at the same time. The operation is simple, convenient and quick.

[0013] 2. By leveraging the elasticity of the return spring, the pawl engages with the tooth groove of the second gear, preventing the rotating rod from rotating in the opposite direction, thus achieving anti-fall-back locking and ensuring the stability of the mounting bracket.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figures 1-4 An adjustable centrifugal pump mounting bracket includes a mounting plate 1. A rotating column 3 is rotatably mounted on the bottom of the mounting plate 1 via an interlocking bearing. A first gear 4 is keyed to the outer wall of the rotating column 3. A handle 5 is welded to the bottom end of the rotating column 3. Rotating rods 6 are rotatably mounted on the four corners of the bottom of the mounting plate 1 via interlocking bearings. A second gear 8 is keyed to the top of the rotating rod 6. The second gear 8 meshes with the first gear 4. A locking mechanism is provided on one side of the second gear 8. A threaded groove 7 is provided on the outer wall of the rotating rod 6. A support cylinder 9 is threadedly connected to the bottom end of the rotating rod 6 via the threaded groove 7. Turning the handle 5 causes the rotating column 3 to rotate, thereby causing the first gear 4 to rotate. Under the action of the first gear 4 meshing with the second gear 8, the rotating rod 6 rotates. Under the action of the threaded connection between the rotating rod 6 and the support cylinder 9, the rotating rod 6 moves within the support cylinder 9, thereby causing the mounting plate 1 to move, and thus adjusting the height of the mounting bracket. A horizontal plate 10 is welded between the two support cylinders 9, and a slider 11 is welded to the top of the horizontal plate 10 to restrict the support cylinders 9 from rotating with the rotating rod 6.

[0018] The mounting plate 1 is provided with two slide grooves 2, and the slider 11 slides in the slide grooves 2 to improve the smoothness of the movement of the slider 11.

[0019] The bottom of the mounting plate 1 is fixed with two protective boxes 13 by bolts. The two protective boxes 13 are fixed with fixing plates 14 on both sides by bolts. The two protective boxes 13 wrap around the outside of the first gear 4. The protective boxes 13 protect the first gear 4 and the second gear 8 to prevent foreign objects from entering and affecting the rotation of the first gear 4 and the second gear 8.

[0020] The locking mechanism includes multiple pawls 16. Rectangular slots 15 are provided at both corners of the protective box 13. The pawls 16 are rotatably connected in the rectangular slots 15 via rotating shafts. The pawls 16 mesh with the second gear 8. Return springs 17 are sleeved at both ends of the rotating shaft of the pawls 16. Under the elastic action of the return springs 17, the pawls 16 lock the tooth grooves of the second gear 8, preventing the rotating rod 6 from rotating in the opposite direction, thereby achieving anti-fall-back locking and ensuring the height stability of the mounting plate 1.

[0021] The protective box 13 has a first clearance groove 18 and two second clearance grooves 1801 running through the top and bottom. The slider 11 is located in the first clearance groove 18, and the rotating rod 6 is located in the second clearance groove 1801. The first clearance groove 18 is for the slider 11 to pass through, and the second clearance groove 1801 is for the rotating rod 6 to pass through. This does not interfere with the movement of the components and can also play a protective role.

[0022] A rubber block 12 is glued to the bottom of the support cylinder 9 to increase the friction with the ground and prevent the device from sliding.

[0023] The working principle of this embodiment is as follows: In use, the centrifugal pump is fixed to the top of the mounting plate 1 by bolts. When it is necessary to adjust the height of the mounting bracket, turn the handle 5 to drive the rotating column 3 to rotate, thereby driving the first gear 4 to rotate. Then, under the action of the first gear 4 and the second gear 8 meshing, the rotating rod 6 is driven to rotate. Under the action of the threaded connection between the rotating rod 6 and the support cylinder 9, the rotating rod 6 moves upward in the support cylinder 9, thereby driving the mounting plate 1 to move upward, thereby raising the height of the mounting bracket. At this time, the pawl 16 can move along the second gear 8. After adjustment, the pawl 16 engages with the second gear 8 to lock the second gear 8 and maintain the height. When it is necessary to lower the height of the mounting bracket, pull the pawl 16 to disengage from the second gear 8, but do not release it. Then turn the handle 5 in the opposite direction. Under the action of the first gear 4 and the second gear 8 meshing, the rotating rod 6 moves downward in the support cylinder 9, thereby lowering the height of the mounting bracket. Then release the pawl 16. The elastic action of the return spring 17 causes the pawl 16 to return to its original position. The pawl 16 engages with the second gear 8, locking the height of the mounting bracket.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
