Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figure 1-8 , a specific embodiment of the present invention is:

[0026] As Figure 1 shown, a device for installing and maintaining a water pump in a hydropower plant is composed of a rail vehicle 1 and a rail 2. The rail vehicle 1 is a device for placing the water pump and can move and be fixed along the rail 2. By installing the rail 2 on the wall of the dam of the hydropower plant, the movement and fixing operations of the water pump can be carried out on the ground, which is convenient for the installation and daily maintenance of large water pumps in the hydropower station.

[0027] As Figures 2-4 shown, two parallel sliding rods 11 are respectively provided on both sides of the bottom of the rail vehicle 1, and a chute 110 is provided on the sliding rod 11. A plurality of vertical rods 12 are provided on both sliding rods 11, the upper ends of the vertical rods 12 are respectively connected to two longitudinal rods 14, and a plurality of cross bars 13 are provided between the two sliding rods 11 and between the two longitudinal rods 14. A rectangular frame is formed by the sliding rod 11, the vertical rod 12, the cross bar 13 and the longitudinal rod 14, wherein the length of the longitudinal rod 14 is less than that of the sliding rod 11. A plurality of bottom support rods 15 are provided between the two vertical rods 12 at the end of the rail vehicle 1, and a plurality of fixed rings 18 are provided on the two vertical rods 12 at the head end. Two fixed rings 18 are in a group at the same height and in the same direction, and can be inserted into the fixed rod 16 and fixed with the fixed bolt 19. A suspension ring 17 is provided on each of the two cross bars 13 at the top and bottom of the head end of the rail vehicle 1 for connecting a hoisting device to hoist and install the rail vehicle 1 onto the rail 2.

[0028] As Figures 5-8As shown, on both sides of the track 2 are two track rods 21. There are protruding track blocks 27 on the track rods 21. The size of the track blocks 27 matches that of the sliding grooves 110. At the bottom end of the track 2, there are stoppers to prevent the rail vehicle 1 from falling off from the bottom of the track blocks 27. The two track rods 21 are connected by multiple track cross bars 22, and there is a track longitudinal bar 23 in the middle of the track cross bars 22. At both ends of the track 2, there is an anchor plate 24 respectively. The anchor plate 24 can be fixed in the dam concrete structure through the anchor rod 25.

There is a towing ring 28 on the track cross bar 22 at the top end of the track 2, which is used to fix the steel cable for hoisting the rail vehicle 1.

[0029] When using this device to install the water pump in the hydropower plant, first fix the anchor plate 25 on the dam wall through the anchor bolt 26, and drill bolt holes at the corresponding positions of the anchor plate 25 and the track rod 21. Use the anchor bolt 26 to install the track 2 to the predetermined position, ensuring that the top end of the track 2 is exposed above the water surface and within the working range of the working surface. Place the rail vehicle 1 flat on the ground and put the water pump in it. Insert the fixing rod 16 into the fixing ring 18 and fix it with the fixing bolt 19. Install the steel cable on the two lifting rings 17 and lift the rail vehicle 1 above the track 2. Manually adjust the position so that the sliding grooves 110 on both sides of the rail vehicle 1 are clamped on the track blocks 27. Slowly lower the rail vehicle 1 so that the rail vehicle 1 enters the water along the track 2 to the predetermined position. Fix the steel cables on the two lifting rings 17 to the towing ring 28 in sequence, and the installation of the water pump can be completed. In the subsequent work of the hydropower station, pull the rail vehicle 1 to the water surface through the steel cable, and the water pump can be repaired and replaced.
