Description

Technical Field

[0001] The utility model relates to a one-time pouring structure for a centrifugal pump, belonging to the technical field of concrete pouring. Background Art

[0002] During the installation and fixation process of existing large water pumps, it is necessary to fix them to the ground by making concrete foundation piers. The commonly used method is the secondary pouring method, that is, during the first concrete pouring process, anchor bolt holes are reserved at the reserved places according to the predetermined design using tools such as wooden sticks; and after the completion of the first pouring, the above-mentioned tools are removed, and then the shims are placed and the pre-installed water pump unit is hoisted to the place for inspection. After confirmation, the secondary pouring is carried out.

[0003] However, the above-mentioned secondary pouring method also has certain shortcomings. For example, the secondary pouring method is not as good as the single pouring method in terms of stability and strength. Therefore, it may cause cracks in the poured concrete pier. More seriously, the centrifugal pump may cause abnormal wear of components such as bearings and impellers due to the above-mentioned cracks and other weak conditions, which may affect the service life. Utility Model Content

[0004] Therefore, the purpose of the present invention is to provide a one-time casting structure for a centrifugal pump, which is used to cast the concrete foundation used by the water pump once, thereby overcoming the problem that the concrete foundation is easily unstable due to secondary casting.

[0005] In order to achieve the above-mentioned object, the present invention provides a one-time casting structure for a centrifugal pump, comprising:

[0006] The casting frame comprises a plurality of mutually perpendicular channel steels connected by bolts;

[0007] At least two embedded parts are evenly fixed on the top of the casting frame, the embedded parts are provided with alignment bolt plates relative to the outer edges of the centrifugal pumps, and the tops of the embedded parts are provided with buckles for fixing the centrifugal pumps;

[0008] Multiple heat dissipation copper pipes are tied to the inner side of the cast frame through steel bars;

[0009] The steel mesh wraps around the casting frame and is used to shape the concrete around the casting frame.

[0010] Furthermore, the pouring frame includes a first pouring frame and a second pouring frame higher than the first pouring frame;

[0011] The embedded parts include first embedded parts and second embedded parts. The first embedded parts are evenly fixed on the top of the first casting frame; the second embedded parts are fixed on the top of the second casting frame.

[0012] Furthermore, the top of the embedded part extends to the outside of the steel mesh.

[0013] Furthermore, the cast structure is provided with a plurality of embedded reinforcement bars;

[0014] The four corners of the embedded parts are connected by bolts and are used to level the centrifugal pump.

[0015] Furthermore, the first casting frame includes four groups of first transverse channel steels and four groups of first vertical channel steels fixed horizontally and vertically, and also includes two groups of first longitudinal channel steels perpendicular to the plane formed by the first transverse channel steels and the first longitudinal channel steels.

[0016] Furthermore, the second casting frame includes four groups of second transverse channel steels and four groups of second vertical channel steels fixed horizontally and vertically, and also includes three groups of second longitudinal channel steels perpendicular to the plane formed by the second transverse channel steels and the second longitudinal channel steels.

[0017] By adopting the above technical solution, the embodiment of the utility model provides a one-time casting structure for a centrifugal pump. The one-time casting structure fixes the embedded parts on the top of the casting frame, and ties a plurality of heat dissipation copper tubes inside the casting frame, and places the centrifugal pump to be placed on the top of the embedded parts to position the buckle, and then uses the steel mesh to limit the outside of the casting frame to complete the concrete casting and shaping, thereby realizing the casting of the concrete base pier through a one-time casting method, avoiding the situation that the concrete base pier is easily cracked and unstable due to the use of secondary casting, thereby affecting the service life of the centrifugal pump.

[0022] The present invention is further described in detail below through the accompanying drawings and specific embodiments. The concrete base of a large centrifugal pump is often made using a secondary pouring method, but this pouring method often causes cracks in the concrete base, thereby affecting the service life of the centrifugal pump.

[0023] Example 1

[0024] like Figures 1 to 3 As shown, the utility model provides a one-time casting structure for a centrifugal pump, comprising:

[0025] The casting frame comprises multiple mutually perpendicular channel steels connected by bolts; the channel surfaces of these channel steels can be adjusted in orientation based on actual usage. Since the centrifugal pump will need to be placed on top of the casting frame using embedded components during later use, the casting frame is constructed by integrating two frames of different heights into a single unit to conform to the external shape of the centrifugal pump. Specifically, the casting frame comprises a first casting frame and a second casting frame that is taller than the first.

[0026] At least two embedded parts, preferably ladder-shaped metal fixings, are evenly fixed to the top of the casting frame. The embedded parts are provided with alignment bolt plates relative to the outer edges of the centrifugal pump, and a buckle is provided on the top of the embedded parts for securing the centrifugal pump. During use, the centrifugal pump will be placed on top of these multiple embedded parts. The alignment bolt plates are used to adjust the horizontal centering and alignment of the coupling between the centrifugal pump and the motor. Furthermore, since the casting frame is divided into a first casting frame and a second casting frame, the embedded parts accordingly include a first embedded part and a second embedded part. The first embedded part is evenly fixed to the top of the first casting frame, and the second embedded part is fixed to the top of the second casting frame. The first and second embedded parts can be embedded parts of the same or different structures, and the orientation of the embedded parts can also be adjusted according to actual needs. In a preferred embodiment, the casting structure is provided with multiple embedded rebars; the embedded rebars are connected to the four corners of the embedded parts by bolts to provide vertical leveling for the centrifugal pump.

[0027] For example, four first embedded parts are evenly fixed to the top of the first casting frame, and four second embedded parts are evenly fixed to the top of the second casting frame. The first and second embedded parts are embedded in a horizontal or vertical direction. The position of the buckle is determined by placing a centrifugal pump on the top. A total of eight alignment bolt plates are installed on the first and second embedded parts, and a total of 16 alignment bolts are installed on the outer edges of the centrifugal pumps.

[0028] In addition, the first casting frame includes four groups of first transverse channel steels and four groups of first vertical channel steels fixed horizontally and vertically, and also includes two groups of first longitudinal channel steels perpendicular to the plane formed by the first transverse channel steels and the first longitudinal channel steels. The second casting frame includes four groups of second transverse channel steels and four groups of second vertical channel steels fixed horizontally and vertically, and also includes three groups of second longitudinal channel steels perpendicular to the plane formed by the second transverse channel steels and the second longitudinal channel steels.

[0029] Multiple heat-dissipating copper tubes are tied to the inside of the casting frame with rebar. A steel mesh wraps around the casting frame to shape the concrete around it. Heat is dissipated during the casting process. When the steel mesh covers the top of the casting frame, the top of the embedded part extends beyond the steel mesh, securing the centrifugal pump via a buckle.

[0030] The embodiment of the present invention provides a one-time casting structure for a centrifugal pump. First, the embedded parts are fixed on the top of the casting frame, and a plurality of heat dissipation copper tubes are tied inside the casting frame. The centrifugal pump to be placed is placed on the top of the embedded parts to position the buckle. Then, the steel mesh is used to limit the outside of the casting frame to complete the concrete casting and shaping. Thus, the casting of the concrete base pier is realized through a one-time casting method, avoiding the situation that the concrete base pier is not firm and cracks may appear due to secondary casting, thereby affecting the service life of the centrifugal pump.
