Description

Technical Field

[0001] This utility model specifically relates to the field of centrifugal pump support technology, and in particular to a mounting bracket with a stable center of gravity. Background Technology

[0002] Compared to conventional water pumps, centrifugal pumps have an additional centrifugal chamber structure, also known as a volute (discharge chamber). In existing technology, when a centrifugal pump is installed using a bracket, the pump's mounting feet are fixed to one end of the bracket, and there is no support structure on the bracket for the volute at the other end. Therefore, the volute is generally suspended in the air. If the distance between the volute and the pump body is long, the centrifugal pump's center of gravity will become unstable after long-term use, the bolts at the fixing point between the bracket and the centrifugal pump will easily loosen, and the volute end of the centrifugal pump will "nod".

[0003] To better address the problem of unstable center of gravity during centrifugal pump installation and further improve installation stability, this application proposes a new support structure that differs from existing technologies by adding a support structure for the volute. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a mounting bracket with a stable center of gravity.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A stable mounting bracket includes two C-shaped frames and a movable frame. Sliding strips are welded to one outer wall of each of the two C-shaped frames. The movable frame has a C-shaped structure and two symmetrically arranged diagonal braces are welded to it. The diagonal braces are perpendicular to the movable frame. A common lower clamping ring is welded between the two diagonal braces. A support column is vertically fixed between the lower clamping ring and the movable frame. A matching upper clamping ring is fixed to the lower clamping ring by bolts and washers. A rubber pad is provided between the lower clamping ring and the upper clamping ring.

[0006] Furthermore, multiple connecting plates are welded between the two ends of the C-shaped frame.

[0007] Furthermore, two mounting frames are fixed on the C-shaped frame, and threaded mounting holes are opened on the two mounting frames.

[0008] Furthermore, the C-shaped frame has multiple fixing holes, and the first bolt is installed in the fixing holes.

[0009] Furthermore, the movable frame has multiple mounting holes, and a second bolt is installed in each mounting hole.

[0010] Furthermore, a counterweight is slidably connected to the slide bar, and multiple evenly distributed positioning holes are opened on one side of the counterweight. A through hole is opened on one side of the outer wall of the C-shaped frame, and positioning bolts of appropriate specifications are installed in the through hole and the positioning hole.

[0011] Furthermore, stiffening plates are welded between the two ends of the C-shaped frame.

[0012] The beneficial effects of this utility model are as follows: 1. By setting up a movable frame, lower clamping ring, and upper clamping ring, a support structure for the centrifugal pump volute is added to the bracket, thereby improving the stability of its installation.

[0013] 2. By incorporating sliders and counterweights, the device not only provides a support structure but also a counterweight adjustment structure, further enhancing the stability of the support frame. Attached Figure Description

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. It should be noted that, unless otherwise explicitly specified and limited, the terms "installation", "connection", and "setting" should be interpreted broadly. For those skilled in the art, the specific meaning of the above terms in this patent can be understood according to the specific circumstances.

[0017] Reference Figure 1-5 A mounting bracket with a stable center of gravity, comprising two C-shaped brackets 1 and a movable bracket 7; Multiple connecting plates 2 are welded between the two ends of the two C-shaped frames 1, and stiffening plates 5 are welded between the two C-shaped frames 1, thereby connecting the two C-shaped frames 1, and the two C-shaped frames 1 are set back to back. Two mounting frames 6 are welded onto the two C-shaped frames 1. The two mounting frames 6 have threaded mounting holes. The spacing between the two mounting frames 6 and the position of the threaded mounting holes can be set according to the model of the centrifugal pump to be fixed, that is, according to the fixing foot spacing and bolt hole diameter of the centrifugal pump of that model. This allows the mounting bracket of this structure to be used for the installation of centrifugal pump of that model in the future. The movable frame 7 has a C-shaped structure, and two symmetrically arranged diagonal braces 8 are welded on the movable frame 7. The diagonal braces 8 are perpendicular to the movable frame 7. A lower clamping ring 9 is welded between the two diagonal bracing bars 8. A matching upper clamping ring 11 is fixed to the lower clamping ring 9 by bolts and washers. Both the lower clamping ring 9 and the upper clamping ring 11 are semi-circular ring structures, and both the lower clamping ring 9 and the upper clamping ring 11 are welded with connecting ears. A support column is vertically fixed between the lower clamping ring 9 and the movable frame 7; A rubber pad 10 is provided between the lower clamping ring 9 and the upper clamping ring 11. The specifications of the lower clamping ring 9, the upper clamping ring 11, and the rubber pad 10 can be selected according to the actual outer diameter of the volute. That is, the radius of the lower clamping ring 9 and the upper clamping ring 11 is determined according to the outer diameter of the volute of this model of centrifugal pump, so that the lower clamping ring 9 and the upper clamping ring 11 of this structure can be used for the installation of this model of centrifugal pump. The rubber pad 10 is a strip of rubber pad wrapped around the outer diameter of the volute, thereby preventing the lower clamping ring 9 and the upper clamping ring 11 from wearing down the skin of the volute. The two C-shaped frames 1 have multiple fixing holes, and the first bolt 101 is installed in the fixing holes to fix the device. The movable frame 7 has multiple mounting holes, and a second bolt 701 is installed in the mounting holes to fix the movable frame 7 to the C-shaped frame 1.

[0018] The C-shaped frame 1, connecting plate 2, slide bar 3, stiffening plate 5, mounting frame 6, movable frame 7, diagonal brace 8, lower clamping ring 9, and upper clamping ring 11 mentioned above can be made of corrosion-resistant metal materials, such as stainless steel or aluminum alloy. Alternatively, all of the above structures can be coated with a wear-resistant and corrosion-resistant coating, such as a ceramic coating.

[0019] The working principle of this embodiment is as follows: When in use, the fixing feet of the centrifugal pump are fixed on the mounting frame 6, and the lower clamping ring 9 and the upper clamping ring 11 are used to support the outer diameter of the volute to make it stable. Example

[0020] The difference between this embodiment and embodiment 1 is that a sliding strip 3 is welded to one outer wall of each of the two C-shaped frames 1, and a counterweight 4 is slidably connected to the sliding strip 3. The specifications of the counterweight 4 are adapted to the specifications of the two C-shaped frames 1. The counterweight 4 has multiple evenly distributed positioning holes 12 on one side. The number of positioning holes 12 can be determined according to the actual situation. The outer wall of one side of the C-shaped frame 1 has a through hole. The position of the counterweight 4 is fixed by installing positioning bolts 13 of appropriate specifications in the through hole and the positioning hole 12.

[0021] Working principle of this embodiment: After installation, the positioning bolt 13 can be loosened first, the counterweight 4 can be moved, and then the positioning bolt 13 can be fixed. When there are 5 positioning holes 12, and the positioning bolt 13 is connected to the middle positioning hole 12 on the counterweight 4, the counterweight 4 is in the middle position, and the counterweight 4 is 2 standard distances away from each end. When the positioning bolt 13 is connected to the positioning holes 12 at both ends of the counterweight 4, the counterweight 4 is located at both ends of the C-frame 1, with a standard distance of 4 units from the other end.

[0022] When the positioning bolt 13 is connected to the second or fourth positioning hole 12, the counterweight 4 is 1 standard distance and 3 standard distances away from the two ends of the C-shaped frame 1, respectively. The fixed position can be selected according to the actual situation, so as to stabilize the two C-shaped frame 1 chassis.

[0023] 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.
