Description

Technical Field

[0002] A pump station is a facility used to lift or transport water or other liquids. It is widely used in water conservancy projects, urban water supply, sewage treatment, farmland irrigation and other fields. A pump station is usually composed of a pump room, main pump, pipeline, control system, etc. The pump room is the main building of the pump station, used to accommodate the main pump and other equipment. The main pump is the core equipment of the pump station, responsible for lifting the liquid from a low place to a high place or transporting it to a distant place; the pipeline is the channel for transporting the liquid; the control system is used to monitor and adjust the operating status of the pump station.

[0003] The main pump is usually fixed to the base with bolts, and then fixed to the anchor bolts on the cement base with bolts. Since the main pump and the base are usually made of metal, they are relatively bulky. Since there are usually through holes on the side of the base (similar to the pallet used in logistics), the main pump is usually transported to the pump room by forklift or crane. Since the area inside the pump room is relatively small and there are many internal equipments, and the forklift is large in size, it is difficult to accurately place the main pump and the base in the appropriate area. If a crane is used, it is difficult to keep the main pump in a horizontal state for transportation, so it is difficult to directly install the base on the anchor bolts on the cement base.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figures 1 to 9In an embodiment of the present invention, a device for fixing the base of a main pump of a pump station includes two symmetrical moving mechanisms 1 for moving the main pump and the base to an installation area. The moving mechanism 1 includes two symmetrical bottom plates 11. The bottom surface of the bottom plate 11 is rotatably connected with a connecting column 12. The bottom surface of the connecting column 12 is fixedly connected with a fixing seat 13. A hub motor 14 is rotatably connected between two opposite side surfaces inside the fixing seat 13. A roller 15 is fixedly connected to the outer wall of the hub motor 14. A reduction motor 16 is fixedly connected to the top surface of the bottom plate 11. The output end of the reduction motor 16 passes through the bottom plate 11 at the corresponding position and is fixedly connected to the connecting column 12 at the corresponding position. The connecting mechanism 2 is fixedly connected between the two moving mechanisms 1 to increase the stability of the two moving mechanisms 1. Two symmetrical lifting mechanisms 3 are arranged inside the connecting mechanism 2 to control the lifting and lowering of the main pump and the base. Two symmetrical fastening mechanisms 4 are arranged on the top surfaces of the lifting mechanisms 3 at corresponding positions to fix the base to the anchor bolts on the cement base through nuts. The fastening mechanisms 4 include a slide plate 41 that slides on the top surface of the lifting mechanism 3 at the corresponding position. The top surface of the slide plate 41 is provided with a plurality of rotating components 42 for screwing nuts. The top surface of the slide plate 41 is provided with a limiting component 43 for limiting the plurality of rotating components 42.

[0020] Specifically, first, the main pump is fixed on the base using bolts. Then, driven by the four hub motors 14, the connecting mechanism 2, the lifting mechanism 3, and the fastening mechanism 4 are moved to the location of the main pump, and the main pump is positioned inside the connecting mechanism 2. By activating the lifting mechanism 3, the main pump is lifted. Then, again driven by the four hub motors 14, the main pump and the base are moved above the cement foundation in the pump station, and the anchor bolts on the cement foundation are aligned with the mounting holes on the base. Then, driven by the lifting mechanism 3, the main pump and the base are lowered until the base contacts the cement foundation and the anchor bolts on the cement foundation are inserted into the mounting holes on the base. By moving the rotating assembly 42, the axis of the rotating assembly 42 is aligned with the axis of the mounting hole. By placing a nut inside the rotating assembly 42 and rotating the rotating assembly 42, the nut can be driven to rotate, and the rotating nut can move downward along the corresponding anchor bolt until the nut is in close contact with the base. At this time, the base is installed on the cement foundation through the action of the nut and the anchor bolt. By driving the four rollers 15 in one direction using the reduction motor 16 and moving the device away from above the cement foundation through the four hub motors 14, the device can control the steering of the rollers 15 at the corresponding positions through the reduction motor 16, and then move the device through the drive of the hub motors 14. Since the device is small in size, it is convenient to move in some pump stations with small spaces and can accurately install the main pump on the cement foundation. Moreover, by placing a nut inside the rotating assembly 42 and rotating the rotating assembly 42, the nut can be automatically screwed onto the outer wall of the anchor bolt to fix the base, eliminating the need for manual fixing of each nut one by one, thus improving the installation efficiency of the main pump base.

Moreover, through the action of two double-headed cylinders 25, the storage plate 24 and two insertion plates 26, the two moving mechanisms 1 and two C-shaped frames 21 can be integrated into a whole to increase the stability during movement.

[0024] Embodiment 2

[0025] As Figure 4 shown, in this embodiment, rectangular grooves 22 are formed on the opposite side surfaces of the two C-shaped frames 21. A vertical rod is fixedly connected between the inner top surface and the inner bottom surface of the rectangular groove 22. Through holes 23 communicating with the rectangular grooves 22 at corresponding positions are formed through the opposite side surfaces inside the C-shaped frames 21. The lifting mechanism 3 includes two symmetric moving plates 31 slidably connected in the rectangular grooves 22 at corresponding positions and slidably penetrating through the vertical rods at corresponding positions.

Two symmetric single-headed cylinders 33 are fixedly connected between the C-shaped frames 21 at corresponding positions and both ends of the adapter plate 32.

[0026] In this embodiment, the driving of two single-headed cylinders 33 can control the lifting of the two moving plates 31 at corresponding positions, so as to facilitate the control of lifting or lowering the main pump and the base.

[0029] In this embodiment, a nut is placed inside the hexagonal shallow groove 425 and is attracted by the magnet at the corresponding position. Because the bottom surface of the nut is in contact with the base under the action of spring 1, when the anchor bolt passes through the mounting hole, spring 1 will be compressed to separate the nut from the base. When the driving motor 415 is driven, multiple connecting shafts 421 at the corresponding position can be driven to rotate. The rotating connecting shafts 421 can drive the nuts at the corresponding position to rotate.
