Description

Technical Field

[0001] This invention belongs to the field of water conservancy engineering technology, specifically relating to a tooling for precise positioning and installation of pre-embedded parts for water conservancy gate slots. Background Technology

[0002] In the construction of water conservancy and hydropower projects, gates are key equipment for controlling water flow and regulating water levels. The gate slot embedded parts serve as the track and support for the opening and closing of the gates. Their installation accuracy directly determines the smoothness of the gate operation, the sealing effect, and even the safety and lifespan of the entire water conservancy project. The gate slot embedded parts usually include the main rail, the reverse rail, the bottom sill, the lintel, and the water-stop seat plate, which need to be precisely positioned in the concrete structure of the gate pier or gate wall.

[0003] In the prior art, for example, the national patent CN222124287U discloses a device for measuring the position of embedded parts in the gate slot of a concrete arch dam. This patent states that the device is first moved to the flat ground of the arch dam, and the positioning component is used to measure the pre-embedded position. The moving seat slides on two guide rods to realize the measurement and adjustment of the lateral position, and the limiting block slides vertically on the limiting guide groove to realize the measurement and adjustment of the vertical position.

[0004] However, traditional devices still have the following problems when in use: Because the moving seat and the limiting block usually rely solely on sliding cooperation to achieve horizontal and vertical position adjustment, and lack a reliable locking and fixing structure after adjustment, the overall stability of the device is poor. When using hoisting equipment to lift the embedded parts or to carry out concrete pouring operations, the moving seat and the limiting block are prone to accidental displacement due to external force collisions or vibrations, which causes the embedded parts to deviate from the preset position and generate installation errors. This not only increases the construction cost of secondary correction, but also seriously affects the quality of the gate slot pre-embedded construction and the project progress. Summary of the Invention

[0028] To make the objectives, technical solutions, and advantages of the present invention clearer and more complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

The abutting assembly includes a connecting block 28 and an abutting plate 30, a side block 27 is fixed on the inner side of the movable frame 5, both the side block 27 and the connecting block 28 are of square plate-like structure, a side groove 29 which is a square plate-like groove structure is opened on the side of the connecting block 28, the side block 27 is slidably connected in the side groove 29, a support spring 34 is fixedly connected between the side block 27 and the side surface of the side groove 29, two sets of the side grooves 29 are provided, the two sets of the side grooves 29 are symmetrically distributed about the center of the connecting block 28, the abutting plates 30 are semicircular plates, two sets of the abutting plates 30 are fixed, the two sets of the abutting plates 30 are symmetrically distributed about the center of one side of the connecting block 28. The linkage assembly includes a linkage plate 22, a transverse plate 23, and a first tooth block 25, the transverse plate 23 is a square plate, the transverse plate 23 is slidably connected in the first tooth block 25, the first tooth block 25 is opened on the side of the movable frame 5, the first tooth block 25 is a square plate-like groove, the linkage plate 22 is a semicircular plate, the linkage plate 22 is fixedly connected to the top of the transverse plate 23, a movable groove 24 is opened on the top of the linkage plate 22, the movable groove 24 is a "T"-shaped cylindrical groove, the positioning rod 21 is slidably connected in the movable groove 24, a mounting groove 36 is opened on the side of the movable frame 5, the positioning rod 21 is of a "T"-shaped cylindrical structure, the positioning rod 21 is fixedly connected to the top of the mounting groove 36, a spring is fixed between the surface of the positioning rod 21 and the inner top surface of the movable groove 24, the spring is sleeved on the outer annular surface of the positioning rod 21. The hoisting assembly includes a positioning block 12, a bearing plate 18, and a second tooth block 26, a second guide plate 11 is fixedly connected to the bottom of the movable frame 5, a guide groove 13 is opened on the side of the positioning block 12, the second guide plate 11 passes through the guide groove 13, the second tooth blocks 26 are triangular plates, a plurality of sets of the second tooth blocks 26 are fixed on the top of the positioning block 12, the plurality of sets of the second tooth blocks 26 are distributed in a linear array, the plurality of sets of the second tooth blocks 26 are engaged with the plurality of sets of the first tooth blocks 25, the plurality of sets of the first tooth blocks 25 are fixedly connected to the bottom of the transverse plate 23, and the bearing plate 18 is fixedly connected to the bottom of the positioning block 12.

[0031] In this invention, the positioning block 12 is manually moved as a whole. The movement of the positioning block 12 drives the threaded rod 15 and the bearing plate 18 to move as a whole, thereby achieving the measurement and adjustment of the lateral position. Then, the moving frame 5 is moved as a whole. The moving frame 5 drives the positioning block 12 to move as a whole, thereby achieving the measurement and adjustment of the vertical position. After the adjustment is completed, the handle 8 is manually rotated. The rotation of the handle 8 drives the adjusting rod 7 and the limiting block 10 to rotate. During the rotation of the limiting block 10, the limiting block 10 will make active contact with one side of the connecting block 28 and hold the connecting block 28. The side block 27 is in the side groove 29. Therefore, the connecting block 28 is held and moved towards the linkage plate 22 until one end of the limiting block 10 is located on the connecting block. Within the arc-shaped surface on one side of 28, under the action of the spring between the surface of the positioning rod 21 and the inner top surface of the movable groove 24, the connecting block 28 always maintains close contact with the limiting block 10, so the limiting block 10 will not easily rotate. The movement of the connecting block 28 causes the top holding plate 30 to move into contact with the top of the linkage plate 22. During the process of the connecting block 28 and the top holding plate 30 being held and moving towards the linkage plate 22, the linkage plate 22 will move towards the bottom of the horizontal plate 23 along the positioning rod 21. Therefore, the toothed block 1 25 will mesh with the toothed block 2 26, which can complete the limiting of the moving frame 5 and the positioning block 12, preventing the moving frame 5 and the positioning block 12 from moving laterally and vertically respectively.

[0032] In Example 3, based on Example 2, the auxiliary limiting component includes an auxiliary strip 31 and an auxiliary plate 32. The auxiliary strip 31 is fixedly connected to the top of the connecting block 28. The auxiliary plate 32 has an arc-shaped plate structure and is slidably connected to the outer ring surface of the auxiliary strip 31. There are two sets of auxiliary plates 32 slidably connected. The two sets of auxiliary plates 32 are symmetrically distributed. An elastic rope is fixed between the bottom sides of the two sets of auxiliary plates 32. The auxiliary plate 32 is movably inserted into the receiving groove 33. The receiving groove 33 is a trapezoidal plate groove. Damping protrusions are fixed on the surfaces of the receiving groove 33 and the auxiliary plate 32 that are in contact with each other.

[0033] In this invention, as the connecting block 28 moves closer to the linkage plate 22, the connecting block 28 drives the auxiliary plate 32 to move into the receiving groove 33. The auxiliary plate 32 will be movably inserted into the receiving groove 33. Under the action of the damping protrusions on the surfaces of the two plates and the elastic rope between the two sets of auxiliary plates 32, the auxiliary plate 32 will not easily detach from the receiving groove 33, thus increasing the overall stability of the connecting block 28. At the same time, when it is necessary to move the moving frame 5, the adjusting rod 7 is rotated to drive the limiting block 10 to rotate. Even without the support of the limiting block 10, the connecting block 28 will not easily move. After adjusting the position of the moving frame 5, the adjusting rod 7 is rotated to make the limiting block 10 continue to be in contact with one end of the connecting block 28.

[0034] In Example 4, based on Example 3, the limiting block 10 has an arc-shaped plate structure. Multiple sets of limiting blocks 10 are fixedly connected and arranged in a linear array. The limiting block 10 is in movable contact with one side of the connecting block 28. The side of the connecting block 28 that is in contact with the mounting through groove 20 is provided with an arc-shaped groove that matches it. The side of the positioning block 12 is provided with a threaded hole 14. The groove of the threaded hole 14 is rotatably connected to a threaded rod 15 through a bearing. The threads on the surface of the threaded rod 15 are symmetrically distributed about the center of the positioning block 12. The outer ring surface of the threaded rod 15 is symmetrically rotatably connected to two sets of nuts 16 about the center of the positioning block 12. The top of the nuts 16 is fixedly connected to a stop plate 17. The top of the stop plate 17 is slidably connected in the moving groove 19. The moving groove 19 is opened on the top of the bearing plate 18 and is a square plate-shaped groove. An arc-shaped groove is opened on the inner side of the moving frame 5, and the limiting block 10 is rotatably connected in the arc-shaped groove.

[0035] In this invention, multiple sets of limiting blocks 10 facilitate the movement of the frame 5 after the movement distance is adjusted. Any set of limiting blocks 10 can support the connecting block 28, thus completing the overall limiting of the moving frame 5 and the positioning block 12. Manually rotating the threaded rod 15 drives the two sets of nuts 16 to move closer or further apart. The nuts 16 drive the abutment plate 17 to move and finely adjust the distance, ensuring that the bottom of the abutment plate 17 contacts the inner walls of both sides of the reserved pit of the gate slot pre-embedded part, thus stabilizing the position of the bearing plate 18 and facilitating the subsequent use of hoisting equipment and subsequent pre-embedded construction operations.

[0036] The working principle and usage process of this invention are as follows: After moving the entire device to the target location, the two bases 1 are respectively located on both sides of the reserved pit for the gate slot embedded part. First, manually move the entire positioning block 12. The movement of the entire positioning block 12 drives the threaded rod 15 and the bearing plate 18 to move, thereby realizing the measurement and adjustment of the lateral position. Next, move the entire moving frame 5. The moving frame 5 drives the entire positioning block 12 to move, thereby realizing the measurement and adjustment of the vertical position. After completing the adjustment, manually turn the handle 8. The rotation of the handle 8 drives the adjusting rod 7 and the limiting block 10 to rotate. During the rotation of the limiting block 10, the limiting block 10 will make active contact with one side of the connecting block 28 and hold the connecting block 28. The side block 27 is in the side groove 29. Therefore, the connecting block 28 is held and moved horizontally towards the linkage plate 22 until one end of the limiting block 10 is located in the arc-shaped surface opened on one side of the connecting block 28, between the surface of the positioning rod 21 and the inner top surface of the movable groove 24. Under the action of the spring, the connecting block 28 always maintains close contact with the limiting block 10, so the limiting block 10 will not easily rotate. The movement of the connecting block 28 causes the top holding plate 30 to move into contact with the top of the linkage plate 22. During the process of the connecting block 28 and the top holding plate 30 being pushed towards the linkage plate 22, the linkage plate 22 will move towards the bottom of the horizontal plate 23 along the positioning rod 21. Therefore, the toothed block 1 25 will mesh with the toothed block 2 26, which can complete the limitation of the moving frame 5 and the positioning block 12, preventing the moving frame 5 and the positioning block 12 from moving laterally and vertically respectively. Manually rotating the threaded rod 15 drives the two sets of nuts 16 to move closer or further away from each other. The nuts 16 drive the abutment plate 17 to move and make fine adjustments to the distance, ensuring that the bottom of the abutment plate 17 contacts the inner walls of both sides of the gate slot pre-embedded part, thus stabilizing the position of the bearing plate 18 and facilitating the subsequent use of hoisting equipment and subsequent pre-embedded construction operations.
