Description

Technical Field

[0001] This utility model relates to the field of water conservancy construction technology, specifically a positioning mechanism for pile driving in water conservancy construction. Background Technology

[0002] When constructing bridges across rivers, pile driving is a crucial part of the foundation engineering, and its quality directly affects the stability and service life of the bridge. The complex and variable river environment, with its varying water flow, geological conditions, and ecological requirements, presents unique challenges to pile driving construction. Reinforced concrete piles are the most widely used type of pile foundation in river bridge construction, characterized by high bearing capacity and good durability. Construction typically employs either precast piles or cast-in-place piles. Precast piles offer stable quality and fast construction speed, while cast-in-place piles are more suitable for complex geological conditions. During construction, strict control of pile verticality (deviation generally not exceeding 1%) and positional deviation is necessary to ensure accurate pile positioning. Reinforced concrete piles are particularly suitable for large-scale river bridge projects with rapid water flow and complex geological conditions.

[0003] When driving piles in a river, cofferdams are set up in the construction area to avoid the impact of the river water. The existing cofferdam setup or the positioning of the pile driving location is done by boat, which is greatly affected by the river water, reducing the accuracy of positioning and the efficiency of pile driving.

[0024] Please see Figure 1-3 This utility model provides a technical solution: a positioning mechanism for pile driving in water conservancy construction, including two crossbeams 1 set on both banks of the river. The main body of the crossbeam 1 is composed of multiple segments spliced ​​together. The main body of the crossbeam 1 is provided with integrally formed reinforcing rods at the front and rear. The crossbeam 1 is provided with a first connecting plate 11 and a second connecting plate 12 whose lateral position is adjustable. The first connecting plate 11 and the second connecting plate 12 are provided with the same longitudinal block 3 whose longitudinal position is adjustable.

[0025] Below the longitudinal block 3, a controllable clamp 5 is provided for holding construction components. The bottom surface of the longitudinal block 3 is provided with a lifting component 4 for adjusting the height of the controllable clamp 5. The lifting component 4 can be a cylinder. The lifting component 4 is connected to the controllable clamp 5. The controllable clamp 5 can hold the main components of the cofferdam, steel sheet piles or wooden plank piles. The controllable clamp 5 can also hold the drill bit of the drilling rig used for auxiliary pile driving. By setting up the crossbeam 1, the lifting component 4, the longitudinal block 3 and the controllable clamp 5, it is convenient to drive the clamped construction components to adjust their position in the horizontal, vertical and vertical directions, so as to move the construction components to the predetermined position.

[0026] The crossbeam 1 has a movable groove 6, and a drive wheel 7 is provided on the movable groove 6. A double-headed motor 8 is provided between the two crossbeams 1. The output shaft of the double-headed motor 8 is provided with a rotating shaft 9. The rotating shaft 9 is fixed to the drive wheel 7. The two drive wheels 7 are connected to the first connecting plate 11.

[0027] The movable groove 6 is provided with two transmission wheels 10. The two transmission wheels 10 correspond to the two crossbeams 1 and are connected to the second connecting plate 12. By setting up a double-headed motor 8, a drive wheel 7 and transmission wheels 10, it is convenient for the longitudinal block 3 to drive the construction components to move laterally.

[0028] A connecting rod 2 is provided between the first connecting plate 11 and the second connecting plate 12, and the first connecting plate 11 and the second connecting plate 12 are connected to the same longitudinal block 3.

[0029] The first connecting plate 11 and the second connecting plate 12 are respectively provided with a first moving groove 13 and a second moving groove 14, and the first moving groove 13 and the second moving groove 14 are respectively provided with a transmission screw 15 and a limiting rod 16.

[0030] A servo motor 17 is provided on the first connecting plate 11. The output shaft of the servo motor 17 is fixed to the transmission screw 15. A transmission block 18 is provided on the transmission screw 15. The transmission block 18 is fixed to the longitudinal block 3. A driven block 19 is provided on the limiting rod 16. The driven block 19 is fixed to the longitudinal block 3. A leveling component for keeping the crossbeam horizontal is provided at the bottom of the crossbeam. The crossbeam is fixed to the riverbank through the leveling component. By setting the transmission screw 15, the limiting rod 16 and the servo motor 17, it is easy to drive the construction components to move longitudinally. Thus, the pile driving positioning mechanism for water conservancy construction can reduce the impact of the river and quickly transport the construction components to the predetermined position, thereby further improving the construction efficiency.

[0031] Working principle: Construction personnel first use the controllable clamp 5 to hold the piling construction components, such as steel sheet piles. Then, the double-headed motor 8 is turned on to rotate the drive wheel 7, causing the first connecting plate 11 and the second connecting plate 12 to move the longitudinal block 3 laterally. This causes the lifting component 4 to move, which in turn moves the controllable clamp 5 and the held steel sheet pile laterally to the vicinity of the predetermined construction position. Once the lateral position is set, the servo motor 17 is turned on to rotate the transmission screw 15, causing the transmission block 18 to move. This, in conjunction with the driven block 19, causes the longitudinal block 3 to move longitudinally. This, along with the controllable clamp 5, completes the longitudinal position adjustment of the steel sheet pile. Then, the lifting component 4 is turned on to lower the steel sheet pile to the bottom of the river. The lifting component 4 continues to descend and apply force. Combined with the traditional piling method, the steel sheet pile is driven into the bottom of the river. By repeating the above operations, multiple steel sheet piles can be quickly transported to the predetermined position and installed to form a cofferdam, which is then used in conjunction with subsequent piling construction.

[0032] The controllable clamp 5 can also hold the construction drill bit, move the drill bit to the predetermined position, and use the drill bit to drill the positioning hole to be piled at the predetermined position, which facilitates subsequent pile driving construction. Thus, the pile driving positioning mechanism for water conservancy construction can reduce the impact of the river and quickly transport the construction components to the predetermined position, thereby further improving the construction efficiency.
