[0032] like Figure 1 , Figure 2 , Figure 5 and Figure 8As shown, a large-scale hydropower project embedded steel pipe precise positioning construction equipment includes a support frame 1, characterized in that the bottom of the support frame 1 is fixedly connected with a support leg 13 by bolts, and a total of four support legs 13 are provided, and the four support legs 13 are symmetrically arranged at the bottom of the support frame 1 in groups of two, and two bases 14 can be provided through the four support legs 13, and the support frame 1 can be stably horizontally supported by the two bases 14, and the bottom ends of the support legs 13 are fixedly connected with the base 14 by bolts, and the inner side of the support frame 1 is provided with an embedded steel pipe horizontal moving component 2, wherein the embedded steel pipe horizontal moving component 2 includes: a rectangular through groove 21 running through the central position of the top of the support frame 1, and a first electric push rod 22 is fixedly connected with the central position of the outer wall of one side of the support frame 1 by bolts, and the first electric push rod 22 is fixedly connected with a moving platform 23 through the output end of one side thereof, and a penetrating guide hole 24 is opened on the outer wall of one side of the moving platform 23, and a guide column 25 is welded on the inner wall of one side of the rectangular through groove 21, and the guide column 25 passes through the guide hole 2 4, there are two guide holes 24 and two guide posts 25, and the two guide holes 24 and the two guide posts 25 are symmetrically opened on the outer wall of the moving platform 23 and symmetrically welded on the inner wall of the rectangular through groove 21, respectively. Through the cooperation of the guide posts 25 and the guide holes 24, the moving platform 23 can be stably moved horizontally inside the rectangular through groove 21, and stable support can be provided for the moving platform 23; when working, when adjusting the horizontal position of the moving platform 23, the first electric push rod 22 is controlled to drive the moving platform 2 through the output end on one side thereof. 3 moves, and under the guidance of the guide column 25 and the guide hole 24, the moving platform 23 is stably moved horizontally inside the rectangular through groove 21, thereby realizing the horizontal movement of the embedded steel pipe docking angle adjustment component 3 on the moving platform 23, and the two ends of the embedded steel pipe are clamped and fixed by the embedded steel pipe docking angle adjustment component 3, and the embedded steel pipe is horizontally moved by the embedded steel pipe horizontal moving component 2, so that one end of the clamped embedded steel pipe can be in close contact with the other section of the embedded steel pipe, thereby realizing the subsequent connection and fixing operation.

[0033] like Figures 1 to 5As shown, as a further embodiment of the present invention, a pre-buried steel pipe docking angle adjustment component 3 is arranged on the movable platform 23, wherein the pre-buried steel pipe docking angle adjustment component 3 comprises: an arc groove 31 and a through hole 38 opened on the top of the movable platform 23, the arc groove 31 is located on one side of the through hole 38, and an arc tooth plate 32 is fixedly connected to the inner wall of one side of the arc groove 31 by a nut, the centers of the through hole 38, the arc groove 31 and the arc tooth plate 32 are at the same center, and by using the same center setting, the rotating column 39 at the bottom of the fixing seat 37 can use the center of the through hole 38 as the axis when performing axial circular motion, thereby realizing the pre-buried steel pipe with one end of the pre-buried steel pipe as the center, and the other end of the pre-buried steel pipe performs circular motion, thereby realizing the adjustment of the angle of the pre-buried steel pipe, thereby facilitating the precise docking of one end of the two steel pipes, thereby facilitating the connection and fixing operation, the arc groove 3 1 is provided with a moving frame 33 on the inner side, and a slide rail 34 is integrally formed on the outer wall of one side of the moving frame 33. The cross section of one end of the slide rail 34 is a T-shaped structure. The T-shaped structure can ensure the stability of the slide rail 34 sliding and moving inside the arc groove 31 to prevent the moving frame 33 from falling off. The slide rail 34 and the arc groove 31 are slidably connected. The top of the moving frame 33 is fixedly connected to a first three-phase motor 35 by bolts. The first three-phase motor 35 is fixedly connected to a gear 36 through an output end of one side thereof. The gear 36 and the arc tooth plate 32 are meshed with gear teeth. Transmission can be achieved through the meshing connection. When the gear 36 rotates, the meshing force can make the moving frame 33 move inside the arc groove 31. A fixed seat 37 is welded at the bottom of the moving frame 33. A rotating column 39 is rotatably connected to the inside of the fixed seat 37 and the through hole 38. A limiting disk 15 is welded to the top of the rotating column 39.During operation, most of the existing pre-buried steel pipes for hydropower projects are pre-buried after trenches are dug in the area where they are to be laid, and the steel pipes are laid in the trenches. The steel pipes need to be butt-jointed and installed together section by section. However, it is difficult to make the axes of the two steel pipes coaxial when one end is butt-jointed, which makes it easy for the butt joints of the two steel pipes to have angle deviations, making it inconvenient to subsequently use bolts or welding to install and fix them. The present technical solution can solve the above problems. The specific working method is as follows: first, after clamping the two ends of the pre-buried steel pipe, one end of the pre-buried steel pipe is brought close to one end of the pre-buried steel pipe, and the two pre-buried steel pipes are placed on the same horizontal plane. Since the pre-buried steel pipe is in a clamped suspended state, In this state, the butt joint of the two sections of the embedded steel pipes cannot be accurately butted together, and there is an angle deviation at one end of the two sections of the embedded steel pipes. At this time, the first three-phase motor 35 is controlled to drive the gear 36 to rotate through the output end on one side thereof. Through the meshing connection between the gear 36 and the arc-shaped toothed plate 32, the slide rail 34 slides on the inner wall of the arc groove 31, and the moving frame 33 moves in the arc groove 31. At this time, the position of one end of the embedded steel pipe is adjusted. Since the embedded steel pipe takes one end of the embedded steel pipe as the center of the circle, the other end of the embedded steel pipe performs a circular motion, thereby realizing the adjustment of the angle of the embedded steel pipe, so as to facilitate the accurate butt joint of one end of the two sections of the steel pipe, thereby facilitating the connection and fixing operation. ;

[0034] like Figure 1 , Figure 3 , Figure 6 and Figure 7As shown, as a further embodiment of the present invention, a support plate 4 is welded to the bottom end of the rotating column 39, and a second electric push rod 5 is fixedly connected to the top of the support plate 4 by bolts. The second electric push rod 5 is fixedly connected to a lifting platform 6 through an output end on one side thereof, and a second three-phase motor 7 is fixedly connected to the central position of the outer wall of one side of the lifting platform 6 by bolts. The second three-phase motor 7 is fixedly connected to a first ball screw 8 through an output end on one side thereof, and a second ball screw 9 is fixedly fixed with a key at one end of the first ball screw 8 away from the second three-phase motor 7. The screw threads in the first ball screw 8 and the second ball screw 9 have opposite rotation directions. A concave cavity is provided at the bottom of the lifting platform 6 near the outer side of the first ball screw 8 and the second ball screw 9, and the first ball screw 8 and the second ball screw 9 with opposite screw threads can make the embedded steel pipe clamps 11 on the first ball screw 8 and the second ball screw 9 move toward or away from each other, and then the two embedded steel pipe clamps 11 are used to clamp the embedded steel pipe. The nut seats on the lever 8 and the second ball screw 9 are fixedly connected to the connecting seat 1 through nuts. The bottom of the connecting seat 1 is welded with a pre-buried steel pipe clamp 11, and the top of the connecting seat 1 is integrally formed with a slider 12. The cross section of one end of the slider 12 is a T-shaped structure. The slider 12 and the lifting platform 6 are slidably connected. The stability of the slider 12 moving on the lifting platform 6 can be ensured by the T-shaped structure. When working, when the pre-buried steel pipe is clamped, the second electric push rod 5 is controlled to drive the lifting platform through the output end on one side thereof. 6 moves downward, and the embedded steel pipe clamp 11 at the bottom of the lifting platform 6 moves downward synchronously. When the embedded steel pipe clamp 11 is located on one side of the embedded steel pipe, the second three-phase motor 7 is controlled to drive the first ball screw 8 to rotate through the output end on one side thereof, and the second ball screw 9 at one end of the first ball screw 8 rotates synchronously, and the embedded steel pipe clamps 11 on the first ball screw 8 and the second ball screw 9 move toward each other, and the two embedded steel pipe clamps 11 clamp the embedded steel pipe, which is convenient for subsequent precise positioning construction and docking and fixing.

[0035] The working principle of the present invention is as follows: during operation, when the embedded steel pipe is clamped, the second electric push rod 5 is controlled to drive the lifting platform 6 to move downward through the output end on one side thereof, and the embedded steel pipe clamping plate 11 at the bottom of the lifting platform 6 moves downward synchronously. When the embedded steel pipe clamping plate 11 is located on one side of the embedded steel pipe, the second three-phase motor 7 is controlled to drive the first ball screw 8 to rotate through the output end on one side thereof, and the second ball screw 9 at one end of the first ball screw 8 rotates synchronously. The embedded steel pipe clamping plates 11 on the first ball screw 8 and the second ball screw 9 move toward each other. The two embedded steel pipe clamping plates 11 clamp the embedded steel pipe, bring one end of the embedded steel pipe close to one end of the embedded steel pipe, and make the two sections of the embedded steel pipe on the same horizontal plane. Since the embedded steel pipe is in a clamped and suspended state, the butt joint of the two sections of the embedded steel pipe cannot be accurately butted, and there is an angular deviation at one end of the two sections of the embedded steel pipe. At this time, the first three-phase motor 35 is controlled The output end on one side drives the gear 36 to rotate, and through the meshing connection between the gear 36 and the arc-shaped toothed plate 32, the slide rail 34 slides on the inner wall of the arc groove 31, and the movable frame 33 moves in the arc groove 31. At this time, one end of the embedded steel pipe is adjusted in position. Since the embedded steel pipe takes one end of the embedded steel pipe as the center of the circle, the other end of the embedded steel pipe performs a circular motion, thereby realizing the adjustment of the angle of the embedded steel pipe, thereby facilitating the precise docking of one end of the two sections of steel pipes. The first electric push rod 22 is controlled to drive the movable platform 23 to move through the output end on one side. Under the guidance of the guide column 25 and the guide hole 24, the movable platform 23 is allowed to move stably horizontally on the inner side of the rectangular groove 21, thereby realizing the horizontal movement of the embedded steel pipe docking angle adjustment component 3 on the movable platform 23, and the clamped end of the embedded steel pipe can be in close contact with the other section of the embedded steel pipe, thereby realizing the subsequent connection and fixing operation.
