Hydraulic pumping station

Abstract

The present invention discloses a concrete structure hydraulic pump station of a hydraulic engineering facility, which mainly includes a lifting beam and guide rails, an electric hoist, and a floor layer in a machine room. A vertical straight groove is opened on the wall of the machine room, the upper end of which reaches the ring beam directly, and the lower end is connected to the doorway. The lifting beam and the guide rail extend to the outside of the machine room through the vertical straight groove. A driving motor output shaft hole and an axial flow pump hole are opened on the floor layer, and another horizontal straight groove connects the two holes. The present invention can lift the driving motor and the axial flow pump to the outside of the machine room at one time for direct loading, and vice versa. At the same time, the concrete cover plate of the original driving motor installation position is cancelled, creating conditions for the accurate positioning of the driving motor.

Description

Technical field:

[0001] The invention relates to water conservancy engineering facilities, in particular to a water conservancy pump station with a concrete structure. Background technology:

[0002] Concrete structure pump station is an important facility for farmland water conservancy, especially in plain water network areas. Axial flow pump units are installed in the pump station to pump water for irrigation during drought and for drainage during flood. At the end of the use season, the drive motor and axial flow pump must be sent to the factory for inspection and maintenance. There is a lifting beam above the machine room, and the beam is connected to a guide rail. An electric hoist is installed on the guide rail for lifting the drive motor and axial flow pump. However, these two pieces of equipment are heavy and large. It is labor-intensive, time-consuming and labor-intensive to carry and load and unload them manually, and it is also easy to cause safety accidents, which may damage the equipment or injure people. In addition, the drive motor is installed on the floor layer, and the axial flow pump is installed on the axial flow pump installation platform below the floor layer. However, when lifting the axial flow pump, it enters and exits the floor layer from the drive motor position above the axial flow pump, so a large hole needs to be opened in the floor layer at that location, but the overall size of the axial flow pump is larger than the drive motor, so a concrete cover plate must be used to cover this large hole, and then the drive motor is installed on it. Therefore, every time it is overhauled, the concrete cover plate must be removed to lift the axial flow pump out, and the concrete cover plate must be covered again when it is reinstalled. However, at this time, the position of the concrete cover plate is often not the original position but has been displaced, causing the drive motor to be installed out of position, resulting in unstable operation of the unit, increased vibration, increased noise, severe wear of parts, shortened service life, increased load on the drive motor, and increased power consumption. The displacement of the concrete cover plate is the main factor causing the displacement of the drive motor, so every time it is reinstalled, it must be done like the first time, and an experienced master must be asked to carefully adjust it to ensure smooth operation, which is labor-intensive and time-consuming. Summary of the invention:

[0003] The purpose of the present invention is to provide a hydraulic pump station with a concrete structure, which can easily and quickly transport the axial flow pump and the drive motor to the outside of the machine room for loading and unloading, while eliminating the adverse effect of the above-mentioned concrete cover plate on the accurate positioning of the drive motor installation, creating conditions for the accurate positioning of the drive motor.

[0004] To this end, the technical solution proposed by the present invention is a concrete hydraulic pump station, including a ring beam, a lifting beam and a guide rail connected in an integral manner, a floor layer, an electric hoist installed on the guide rail, a vertical straight groove is opened on the wall of the machine room above the machine room door opening, the upper end of the vertical straight groove reaches the ring beam directly, and the lower end thereof is connected with the door opening, the width of the vertical straight groove is greater than the width of the electric hoist, the lifting beam and the guide rail both extend to the outside of the machine room through the vertical straight groove, a drive motor output shaft hole is opened at the drive motor installation position of the floor layer, the diameter of the drive motor output shaft hole is greater than the coupling diameter, an axial flow pump hole is also opened on the floor layer between the drive motor output shaft hole and the door opening, the diameter of the axial flow pump hole is greater than the outer dimensions of the axial flow pump, and a horizontal straight groove is also opened on the floor layer to connect the drive motor output shaft hole with the axial flow pump hole, and the width of the horizontal straight groove is greater than the diameter of the electric hoist wire rope.

[0005] As can be seen from the above, the present invention can directly lift the drive motor and the axial flow pump from the installation position to the transport vehicle outside the machine room at one time, and vice versa. The original heavy and dangerous loading and unloading work becomes easy, convenient and safe. On the other hand, since the axial flow pump enters and exits the floor layer through the axial flow pump hole, the large hole originally opened at the installation position of the drive motor becomes a small hole, and the concrete cover plate originally covering the large hole is no longer needed, which completely eliminates the main factor of the drive motor installation deviation, thereby creating conditions for the accurate resetting of the drive motor.

[0006] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. Description of the drawings:

[0009] Figure 3 It is a cross-sectional structural diagram of the connection between the lifting beam, guide rail and ring beam;

[0010] Figure 4 It is a schematic diagram of the local structure of the floor layer. Specific implementation method:

[0011] Implementation example Figures 1 to 4 As shown. The concrete hydraulic pump station has a roof 1, and a ring beam 2 is provided under the roof 1. The lifting beam 3 is cast as one piece with the ring beam 2. A vertical straight groove 5 is provided on the wall 7 of the machine room. The upper end of the vertical straight groove 5 reaches the ring beam 2, and the lower end thereof is connected to the door opening 6. The lifting beam 3 and the guide rail 4 connected to the lifting beam 3 extend to the outside of the machine room through the vertical straight groove 5. An iron plate 8 is welded to the bottom surface of the lifting beam 3 at a certain distance, as shown in FIG. Figure 3As shown, the iron plate 8 is welded to the reinforcement 3b in the lifting beam 3, and the guide rail 4 is an I-beam, the top surface of which is welded to the iron plate 8, so that the guide rail 4 and the lifting beam 3 are connected as a whole. Figure 3 3a is the main reinforcement. An electric hoist 14 is installed on the guide rail 4. Figure 2 As shown, the section of the lifting beam 3 and the guide rail 4 extending out of the machine room becomes a cantilever.

[0012] A drive motor output shaft hole 9 is opened at the installation position of the drive motor 18 on the floor layer 13. The diameter of the drive motor output shaft hole 9 is significantly larger than the diameter of the coupling 17 on the drive motor output shaft. The coupling 17 can freely enter and exit the drive motor output shaft hole 9. An axial flow pump hole 11 is opened on the floor layer 13 between the drive motor output shaft hole 9 and the door opening 6. The diameter of the axial flow pump hole 11 is significantly larger than the outer dimensions of the axial flow pump 16. The axial flow pump 16 can freely enter and exit the axial flow pump hole 11. A horizontal straight groove 10 is also opened on the floor layer 13. The horizontal straight groove 10 connects the drive motor output shaft hole 9 with the axial flow pump hole 11. The width of the horizontal straight groove 10 is significantly larger than the diameter of the wire rope of the electric hoist 14. The wire rope can freely enter and exit or move in the horizontal straight groove 10. The horizontal straight groove 10 provides a channel for the lifting axial flow pump wire rope to enter the drive motor output shaft hole 9.

[0013] Figure 2 There is also an axial flow pump installation platform 12, patent number CN201820361430.x axial flow pump installation guide positioning platform 15 has been fixed in advance on the axial flow pump installation platform 12 below the floor layer 13. The axial flow pump 16 is placed on the axial flow pump installation guide positioning platform 15, and when it is overhauled and reinstalled later, the axial flow pump 16 can return to the initial installation position.

[0014] In addition, for safety reasons, the axial flow pump hole 11 and the horizontal straight groove 10 can be covered with a grid-shaped cover or other forms of cover.
