[0037] The following will describe in detail the specific implementation manners of the present utility model with reference to the accompanying drawings.

[0038] As Figure 1-7 shown, a pipe fixing and supporting mechanism for hydropower station construction includes:

[0039] Two sets of lifting components 3; the two sets of lifting components 3 are parallel to each other; a pipe groove 10 with an upward opening is arranged on the moving part of the lifting component 3. When fixing and supporting a pipe, the pipe is placed in the pipe grooves 10 of the two sets of lifting components 3;

[0040] Two sets of guiding components 5; the two sets of guiding components 5 are parallel to each other; the first end of the guiding component 5 is rotatably connected to the moving part of the lifting component 3, the second end of the guiding component 5 is placed on the ground after rotation, and the first end of the guiding component 5 is arranged on the side close to the pipe groove 10. The arrangement of the pipe groove 10 can accommodate and place the pipe, preventing the pipe from shaking after installation.

[0041] As Figure 1-3 shown, in some embodiments, the fixed support mechanism further includes a moving base 1. A plurality of universal wheels are arranged at the bottom of the moving base 1, and the lower ends of the lifting components 3 are fixedly installed on the moving base 1.

[0042] As Figure 1-4 shown, in some embodiments, the lifting component 3 includes a motor 31, a moving block 32, a sliding rod 33, and a threaded rod 34. The motor 31 is vertically installed on the moving base 1, the lower end of the sliding rod 33 is installed on the moving base 1, the sliding rod 33 is parallel to the threaded rod 34. Correspondingly, a sliding hole and a first threaded hole are vertically arranged in the first end of the moving block 32. The sliding hole is parallel to the first threaded hole. The moving block 32 is in limit sliding fit with the sliding rod 33 through the sliding hole, the moving block 32 is in threaded fit with the threaded rod 34 through the first threaded hole, the lower end of the threaded rod 34 is connected to the rotating shaft of the motor 31, and the pipe groove 10 is arranged above the second end of the moving block 32.

[0043] As Figure 7 shown, in some embodiments, the guiding component 5 includes a fixed frame 51, a plurality of guiding wheels 52, and an extension frame 53. The first end of the fixed frame 51 is rotatably connected to the second end of the moving block 32. A sliding groove is arranged along the length direction of the fixed frame 51, the second end of the sliding groove is open, an installation groove is arranged above the sliding groove, and a row of guiding wheels 52 is arranged in the installation groove. The rolling directions of the plurality of guiding wheels 52 are all along the length direction of the fixed frame 51. The extension frame 53 is slidably placed in the sliding groove, and the end of the extension frame 53 away from the fixed frame 51 is placed on the ground when lifting the pipe. By arranging the guiding wheels 52, the pipe can be guided, making it more labor-saving for the pipe to rise, thereby reducing the physical strength of manually handling the pipe.

[0044] As Figure 1 and 3As shown, in some embodiments, a plurality of support seats 2 for supporting the moving block 32 are provided below each moving block 32, and the lower ends of the support seats 2 are mounted on the moving base 1. The support seats 2 are made of rubber. By providing the support seats 2, the moving block 32 can be supported, and buffering can be achieved when it falls to the lowest position.

[0045] As Figure 4-6 shown, in some embodiments, a support block 4 is provided on the side wall of the moving block 32. When the guiding assembly 5 is in a non-use state, the second end of the fixed frame 51 is placed on the support block 4. A baffle is fixedly connected to the front side of the extension frame 53. The baffle is made of a magnetic material, and the support block 4 is made of a magnet. When the extension frame 53 is placed on the top of the support block 4, the baffle and the support block 4 are attracted and fixed to prevent the fixed frame 51 and the extension frame 53 from shaking.

[0046] As Figure 5 shown, in some embodiments, after the pipeline is placed in the pipeline groove 10, an arc-shaped clamping top plate 6 is covered above the pipeline groove 10. One end of the clamping top plate 6 is connected to the moving block 32 through a fastening bolt 8. By providing the clamping top plate 6, the pipeline can be limited, thereby preventing the pipeline from falling off from the inside of the pipeline groove 10.

[0047] As Figure 5-6 shown, in some embodiments, the fixed support mechanism further includes a rolling assembly 7. The rolling assembly 7 includes a mounting block 71 and a threaded column 73. An installation cavity 9 is vertically provided at the bottom of the pipeline groove 10. The mounting block 71 is vertically slidably placed in the installation cavity 9. An arc-shaped groove is provided at the top of the mounting block 71. A second threaded hole is vertically provided on the moving block 32 at the bottom of the installation cavity 9. The threaded column 73 is in threaded cooperation with the second threaded hole. The upper end of the threaded column 73 contacts the bottom of the mounting block 71. The lower end of the threaded column 73 passes through the second threaded hole and is connected to a turning handle.

[0048] As Figure 5 shown, in some embodiments, the fixed support mechanism further includes a plurality of balls 72. A ball groove 72 is provided on the surface of the arc-shaped groove. A plurality of balls 72 are rotatably placed in the ball groove 72.

[0049] As Figure 5 shown, in some embodiments, the radian of the arc-shaped groove is the same as that of the pipeline groove 10. When the bottom of the mounting block 71 contacts the bottom of the installation cavity 9, the arc surfaces of the arc-shaped groove and the pipeline groove 10 overlap.

[0050] In some embodiments, there are four groups of guiding assemblies 5, and every two groups are respectively located on both sides of the moving block 32. Correspondingly, the support blocks 4 for placing the guiding assemblies 5 are also provided on both sides of each moving block 32.

[0051] When the present application is working, the device is pushed to the installation position through the moving base 1, and then the universal wheels at the bottom of the moving base 1 are braked for fixation. The clamping top plate 6 is opened, and by rotating the threaded column 73, under the action of the thread, it pushes the mounting block 71 to move upward, so that the mounting block 71 moves into the pipe groove 10. Then, the extension frame 53 is pulled out from the fixed frame 51 and placed on the ground to form a slope. Then, the pipe is pushed upward from the fixed frame 51 and the extension frame 53. When it is pushed into the pipe groove 10, the pipe falls onto the top of the mounting block 71 and contacts the ball 72. At this time, the pipe can be manually moved left and right to make the pipe slide on the surface of the ball 72. When it is necessary to retract the extension frame 53 and the fixed frame 51, it only needs to be rotated above the support block 4 (as Figure 4 shown). After the adjustment is completed, the threaded column 73 is rotated reversely to make the mounting block 71 and the ball 72 descend and fall into the installation cavity 9, so that the pipe falls into the pipe groove 10. Then, the clamping top plate 6 is flipped to the surface of the pipe, and the clamping top plate 6 is fixed to the top of the moving block 32 through the fastening bolt 8, thereby fixing the pipe. Then, the motor 31 is started, and the output shaft drives the threaded rod 34 to rotate. Under the action of the thread, the moving block 32 on its surface moves upward, and then drives the pipe to move upward to rise to the required installation position, so as to be able to fixedly support the pipe.

[0052] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
