Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] like Figures 1 to 7 As shown, the utility model provides a positioning mechanism for water conservancy project pipeline construction, including:

[0031] Support legs 1, the number of the support legs 1 is four, and a top plate 2 is fixedly installed on the top of each of the four support legs 1;

[0032] An adjusting mechanism 3, the adjusting mechanism 3 is arranged at the bottom end of the top plate 2;

[0033] The rotating mechanism 4 is arranged at the top of the top plate 2;

[0034] Among them, the adjustment mechanism 3 includes a lifting plate 301, which is movably installed at the bottom end of the top plate 2. The left and right sides of the lifting plate 301 are respectively provided with limiting grooves 302. The number of limiting grooves 302 is two. The left and right ends of the two limiting grooves 302 are respectively movably sleeved with movable blocks 303. The top of the movable block 303 is hinged with a movable rod 304. The bottom end of the movable block 303 is movably sleeved with an arc clamping plate 305. The movable rod 304 will move the movable block 303.

[0035] When the top end of the movable rod 304 moves upward, the bottom end of the movable rod 304 will generate a pulling force on the movable block 303, pulling the movable block 303 to move along the inner surface of the limit groove 302. At this time, the arc-shaped clamping plate 305 movably sleeved inside the movable block 303 will also move along with it, thereby adjusting the position of the arc-shaped clamping plate 305, thereby achieving clamping and positioning of water conservancy project pipes of different specifications. At the same time, there is no need for the operator to use bolts to perform positioning operations, thereby improving the applicability and convenience of the water conservancy project pipe positioning mechanism.

[0036] Wherein, the rotating mechanism 4 includes:

[0037] A short threaded rod 401, the short threaded rod 401 is movably sleeved on the inner surface of the middle end of the lifting plate 301, and an upper handle 402 is fixedly sleeved on the top of the outer surface of the short threaded rod 401;

[0038] The cross bar 403 is threadedly sleeved on the outer surface of the short threaded rod 401 , and the left and right sides of the bottom end of the cross bar 403 are respectively hinged to the movable rod 304 .

[0039] When the upper handle 402 is rotated, the short threaded rod 401 will rotate, so that the cross bar 403 threadably sleeved with the short threaded rod 401 drives the top end of the movable rod 304 to move upward.

[0040] Among them, a first vertical plate 5 is fixedly installed on the left side of the bottom end of the top plate 2, and a first sliding block 6 is movably sleeved on the top end of the inner surface of the first vertical plate 5. The top end of the first sliding block 6 is movably connected to the bottom end of the top plate 2, and the right end of the first sliding block 6 is fixedly connected to the left end of the lifting plate 301. A long threaded rod 7 is sleeved on the internal thread of the first sliding block 6. The top end of the long threaded rod 7 penetrates the top plate 2 and extends to the outside of the top plate 2 and is fixedly sleeved with a round handle 8. The bottom end of the round handle 8 is movably connected to the top end of the top plate 2, and the bottom end of the long threaded rod 7 penetrates the first vertical plate 5 and extends to the bottom end of the first vertical plate 5.

[0041] When the round handle 8 is turned, the long threaded rod 7 will rotate, and the first sliding block 6 threadably sleeved with the long threaded rod 7 will move the lifting plate 301 downward.

[0042] Among them, a second vertical plate 9 is fixedly installed on the right side of the bottom end of the top plate 2, and a second slider 10 is movably sleeved on the top end inside the second vertical plate 9. The top end of the second slider 10 is movably connected to the bottom end of the top plate 2, and the left end of the second slider 10 is fixedly connected to the right end of the lifting plate 301.

[0043] The inner surface of the second vertical plate 9 and the outer surface of the second sliding block 10 are both smooth, ensuring that the second sliding block 10 will not get stuck when moving along the inside of the second vertical plate 9 .

[0044] Among them, a card slot 11 is opened inside the arc-shaped clamping plate 305, and the left and right ends of the card slot 11 are movably sleeved with card blocks 12 respectively. The number of card blocks 12 is two, and the outer surfaces of the two card blocks 12 are respectively fixedly sleeved with connecting plates 13. The number of connecting plates 13 is two, and the two connecting plates 13 are both movably sleeved on the inner surface of the movable block 303. The opposite back sides of the two connecting plates 13 are respectively fixedly installed with springs 14, and the other end of the spring 14 is fixedly connected to the inner surface of the movable block 303.

[0045] Due to the existence of the clamping slot 11 and the clamping block 12 , the position of the arc-shaped clamping plate 305 will be locked.

[0046] Among them, the internal movably sleeve of the movable block 303 is connected with a round rod 15 located above the arc-shaped clamping plate 305, the right end of the round rod 15 passes through the movable block 303 and extends to the outside of the movable block 303 and is fixedly sleeved with a lower handle 16, and the left end of the lower handle 16 is movably connected to the right end of the movable block 303.

[0047] When the lower handle 16 is rotated, the round rod 15 will rotate along the inner surface of the movable block 303 .

[0048] Among them, a disc 17 is fixedly sleeved on the left side of the outer surface of the round rod 15, and the disc 17 is movably sleeved inside the movable block 303. Short rods 18 are hinged on the upper and lower sides of the front end of the disc 17 respectively. There are two short rods 18, and the other ends of the two short rods 18 are respectively hinged to the outer surfaces of the two connecting plates 13. The short rods 18 will cause the connecting plates 13 to move.

[0049] When the disc 17 rotates, the short rod 18 will generate a thrust on the connecting plates 13, pushing the two connecting plates 13 to move away from each other.

[0050] The working principle and use process of this utility model:

[0051] First, the operator places the positioning mechanism directly above the construction pipeline of the water conservancy project, and then turns the round handle 8 to rotate the long threaded rod 7. At this time, the first sliding block 6 threadedly connected to the long threaded rod 7 will move downward along the inner surface of the first vertical plate 5 with the lifting plate 301. When the arc-shaped clamping plate 305 moves to both sides of the pipeline with the lifting plate 301, the operator turns the upper handle 402 to rotate the short threaded rod 401. Since the short threaded rod 401 and the cross bar 403 are threadedly connected, the cross bar 403 will move the top of the movable rod 304 upward, so that the bottom end of the movable rod 304 generates a pulling force on the movable block 303, pulling the movable block 303 with the arc-shaped clamping plate 305 along the inner surface of the limiting groove 302 until the pipeline is clamped, thereby realizing the clamping and positioning of pipelines of different specifications, thereby improving the application range of the positioning mechanism.

[0052] When the arc-shaped clamping plate 305 needs to be replaced, the operator turns the lower handle 16 to make the round rod 15 rotate with the disc 17. At this time, as the disc 17 rotates, the short rod 18 hinged to the disc 17 will rotate together, so that the other end of the short rod 18 generates a thrust on the connecting plate 13, pushing the two connecting plates 13 to move away from each other with the two clamping blocks 12 respectively and compressing the spring 14 until the clamping block 12 and the clamping slot 11 are separated. At this time, the clamping block 12 will release the lock on the arc-shaped clamping plate 305, and then the operator can remove the arc-shaped clamping plate 305. The cooperation of various mechanisms realizes the rapid disassembly and replacement of the arc-shaped clamping plate 305, thereby improving its convenience.
