Description

Technical Field

[0001] The invention belongs to the field of pipe pile construction guidance, and in particular relates to a guidance mechanism for deep soft foundation pipe pile construction of a Linjiang sluice pump station project. Background Art

[0002] During the construction of deep soft foundation pipe piles for the Linjiang Sluice Pump Station Project, the gate construction needs to be carried out in the water. Especially when building a sluice in a river, the construction team needs to take special measures, such as using an on-water construction platform, to ensure the safety and smooth progress of the construction. In the process of driving the pipe piles into the soil layer in the water through the construction platform, in order to ensure the depth of the pile driving, it is necessary to connect multiple pipe piles in series, that is, to connect the prefabricated piles one by one and continue to drive them down until the designed depth is reached. In addition, when driving the piles, the driving angle of the prefabricated piles needs to be determined according to the geological conditions, pile type and construction method, as well as the environment and design requirements. After finding the appropriate piling angle, a guide mechanism needs to be installed on the water construction platform. After the pipe piles are kept straight by the guide mechanism, piling can be continued. However, in the process of adjusting on the water construction platform and adjusting the piling direction of the pipe piles, the guide mechanism is not convenient for supporting the pipe piles first and then fine-tuning the position and angle. When deviation occurs, the pipe piles need to be disassembled and adjusted again. Since the construction environment is in the water, it will be affected by the water level and water flow, which is not conducive to maintaining the stability of the pile body during the construction process.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0035] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0036] like Figures 1 to 10 As shown, in one embodiment, a guiding mechanism for deep soft foundation pipe pile construction of Linjiang sluice pump station project includes two clamping jaws 3, and the two clamping jaws 3 are used to clamp the outer periphery of the pipe pile body 36, the two jaws 36 are respectively rotatably connected to the multi-directional sliding mechanism, the clamping surface of each jaw 3 is rotatably connected to a plurality of rollers 4, and the rotation axis of each roller 4 is vertically arranged to the pipe pile body 36, each jaw 3 is equipped with a limit assembly, the limit assembly can limit the rotation of the roller 4, and a rotation drive assembly is arranged between each jaw 3 and the multi-directional sliding mechanism, and the rotation drive assembly can drive the corresponding jaw 3 to move relatively multi-directionally. The multi-directional sliding mechanism rotates, the multi-directional sliding mechanism includes a first threaded driving assembly, and two tripods 1 are arranged on the first threaded driving assembly, the two tripods 1 are arranged parallel to each other, the first threaded driving assembly can adjust the distance between the two tripods 1, an electric slider 2 is arranged on each tripod, a second screw driving assembly is arranged on one side of each electric slider 2, and a clamp 3 is rotatably arranged on the second screw driving assembly, the first threaded driving assembly can drive the tripod 1 to slide along the Y direction, the execution end of the electric slider 2 can drive the second screw driving assembly to slide along the X direction, and the second screw driving assembly drives the clamp 3 to slide along the Z direction.

[0037] like Figure 1 As shown, the first threaded drive assembly is used to threadably drive two tripods 1 to adjust the spacing; two electric sliders 2 are respectively arranged on the top of the two tripods 1, and the two electric sliders 2 are rotatably provided with clamping jaws 3 on the opposite sides, and the clamping surfaces of the two clamping jaws 3 are rotatably connected with multiple rollers 4, and the rotating axis of the rollers 4 is perpendicularly arranged to the pipe pile body 36 clamped by the two clamping jaws 3; the rotation drive assembly is used to drive the clamping jaws 3 to rotate and adjust relative to the electric slider 2; the two limit assemblies are used to limit the rolling of the rollers 4 on the two clamping jaws 3 before adjusting the position or angle of the pipe pile body 36 in the clamping state.

[0038] It should be understood that the pipe pile body 36 is arranged between the two clamping jaws 3, and then the two tripods 1 are synchronously driven to move toward each other through the first threaded drive assembly, thereby driving the two electric slide blocks 2 to move toward each other, and the two electric slide blocks 2 synchronously drive the two clamping jaws 3 to move toward each other, so that the pipe pile body 36 clamps the column. If there is still an angle and position deviation of the pipe pile body 36, the electric slide block 2 is started to move the position, and the clamping jaws 3 adjusted in position can be driven to rotate by the rotation drive assembly, thereby driving the pipe pile body 36 to adjust the angle, so that after the pipe pile body 36 is clamped and guided, the guide angle and the position of the clamping support can be adjusted as needed, avoiding the situation of removing the pipe pile body 36 from the guide mechanism and then adjusting it, which is convenient for re-adjusting the pipe pile body after the guide support;

[0039] It should be further explained that before adjusting the position or angle of the pipe pile body 36 in the clamping state, the two limit assemblies respectively limit the rolling of the rollers 4 on the two clamping jaws 3 to achieve the clamping and positioning of the pipe pile body 36 by the two clamping jaws 3 .

[0040] After adjusting the position and angle, the limit on the rolling of the roller 4 is removed by the limit assembly, and the pipe pile body 36 can be guided and limited between the two clamping jaws 3, and can move along the set ideal angle direction, providing favorable conditions for piling of the pipe pile body 36.

[0041] like Figure 1 As shown, in one embodiment, the first threaded drive assembly includes a fixed frame 5, which is fixedly mounted on a mounting table set on the ground; two tracks 6 are fixedly connected to the surface of the fixed frame 5, and two tripods 1 are slidably set on the two tracks 6; the first motor 7 is fixedly mounted on the surface of the fixed frame 5, and the output end is fixedly connected with a bidirectional screw 8, and the two threaded surfaces of the bidirectional screw 8 are respectively threadedly connected to the two tripods 1.

[0042] It should be understood that when it is necessary to clamp the pipe pile body 36 whose direction and position have been preliminarily adjusted, start the first motor 7, which will drive the two threaded surfaces of the bidirectional screw 8 to threadably drive the two tripods 1 to move toward each other, and the two tripods 1 will synchronously drive the two clamping jaws 3 to approach to clamp and guide the pipe pile body 36.

[0043] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in one embodiment, the electric slider 2 and the clamp 3 are connected by a connecting assembly, which includes a support rail 9, which is fixedly connected to the side of the electric slider 2, and a mounting slider 10 is slidably set on the surface of the support rail 9. The side of the mounting slider 10 is rotatably connected to a support shaft 11, and the support shaft 11 is fixedly connected to the surface of the clamp 3; a second screw drive assembly, which is used to adjust the position of the mounting slider 10 on the surface of the support rail 9.

[0044] It should be understood that if, after the pile body 36 is clamped and the guide angle has been adjusted, the bottom end of the pile body 36 needs to be supported on the ground to prepare for the subsequent piling, the second screw drive assembly can be used to drive the mounting slide 10 to move on the support rail 9 so that the bottom end of the pile body 36 contacts the ground, that is, Figure 1 As shown, the slider 10 slides on the support rail 9 along the Z direction, and the electric slider 2 is a linear drive module of the prior art. The electric slider 2 drives the support rail 9 to slide along the X direction, and then drives the clamp 3 to move through the electric slider 2 until the bottom end of the pipe pile body 36 contacts the ground and the top end is aligned with the pile driver, thereby further adjusting the position of the pipe pile body 36 with the adjusted angle, providing favorable conditions for piling.

[0045] like Figure 2 As shown, in one embodiment, the second screw drive assembly includes a second motor 12, which is fixedly mounted on the surface of the electric slider 2; a threaded rod 13 is fixedly connected to the output end of the second motor 12, and the threaded rod 13 is threadedly connected to the mounting slider 10. It should be understood that when the height of the pipe pile body 36 with the guide angle adjusted needs to be adjusted, the second motor 12 is started, the second motor 12 drives the threaded rod 13 to rotate, and the threaded rod 13 threadably drives the mounting slider 10 to move on the surface of the support rail 9, thereby achieving the adjustment of the height of the pipe pile body 36.

[0046] like Figure 3 , Figure 7 and Figure 8As shown, in one embodiment, the rotation drive assembly includes a third motor 14, which is fixedly mounted on the surface of the electric slider 2, and the output end is fixedly connected to a driving gear 15; the linkage gear 16 is fixedly sleeved on the surface of the support shaft 11 shown, and meshes with the driving gear 15. It should be understood that when the angle of the pipe pile body 36 clamped by the clamping jaws 3 needs to be adjusted, the third motor 14 is started, the third motor 14 drives the driving gear 15 to rotate, the driving gear 15 will synchronously drive the linkage gear 16, and the linkage gear 16 drives the clamping jaws 3 to rotate through the support shaft 11, thereby realizing the adjustment of the guide angle of the pipe pile body 36 clamped on the clamping jaws 3.

[0047] like Figure 2 As shown, in one embodiment, the multiple rollers 4 on the same clamping jaw 3 are evenly divided into two rows, and the two rows of rollers 4 are respectively located at the two ends of the clamping surface of the clamping jaw 3. It should be understood that by arranging the multiple rollers 4 on the same clamping jaw 3 into two rows and distributing them at the two ends of the clamping surface of the clamping jaw 3, it is beneficial to utilize the span of the clamping surface of the clamping jaw 3 to form two height surrounding supports for the pipe pile body 36.

[0048] like Figures 2 to 8 As shown, in one embodiment, the limiting assembly is located between the two rows of rollers 4, and the limiting assembly includes two top pressure plates 17, and the two top pressure plates 17 are slidably arranged on the clamping surface of the clamping jaw 3; two guide rails 18 are respectively fixedly connected to the two top pressure plates 17 and are symmetrically arranged; two linkage pins 19 are respectively slidably arranged in the two guide rails 18; the linkage plate 20 is fixedly connected between the two linkage pins 19, and passes through the clamping jaw 3 and extends to the outside of the clamping jaw 3; the pulling assembly is used to pull the linkage plate 20 before adjusting the position or angle of the pipe pile body 36 in the clamping state, so as to link the guide rails 18 through the linkage pins 19, guide the two top pressure plates 17 to contact the surfaces of the two rows of rollers 4 respectively, and form a friction limit for the rollers 4.

[0049] It should be understood that when it is necessary to limit the rolling of the roller 4, the linkage plate 20 is pulled by the pulling assembly to link the guide rail 18 through the linkage pin 19, guiding the two top pressure plates 17 to contact the surfaces of the two rows of rollers 4 respectively, forming a friction limit on the roller 4, and realizing that the clamping jaws 3 guide and limit the pipe pile body 36 while clamping the pipe pile body 36, so that the pipe pile body 36 and the clamping jaws 3 are relatively fixed, preparing for subsequent angle adjustment and position adjustment.

[0050] like Figures 2 to 8As shown, in one embodiment, the pulling assembly also includes an electric cylinder 21, which is fixedly mounted on the surface of the clamp 3; the moving plate 22 is fixedly connected to the end of the piston rod of the electric cylinder 21, and a first traction rail 24 is opened on the surface, and the first traction rail 24 includes a first inclined groove 2401 and a first vertical groove 2402; the connecting groove 23 is opened on the surface of the linkage plate 20; the first slider 25 is slidably arranged in the connecting groove 23 and a supporting spring 26 is fixedly connected to the inner wall of the connecting groove 23; the first traction pin 27 is fixedly connected to the surface of the first slider 25, and is slidably arranged in the first vertical groove 2402.

[0051] It should be understood that when the linkage plate 20 needs to be pulled, the electric cylinder 21 is started, the electric cylinder 21 pushes the moving plate 22, and the moving plate 22 drives the first traction rail 24 to move. During the movement of the first inclined slot 2401 on the surface of the first traction pin 27, the first traction pin 27 will be pushed, and the first traction pin 27 synchronously drives the linkage plate 20 to move through the first slider 25, and the linkage plate 20 synchronously drives the two linkage pins 19 to move, and the two linkage pins 19 act on the guide rail 18, so that the two top pressure plates 17 move away from each other and approach the two rows of rollers 4 respectively, and finally the two top pressure plates 17 simultaneously and respectively press against and limit the two rows of rollers 4;

[0052] It should be noted that, with the support of the support spring 26, a gradual tightening process is achieved, which is helpful to avoid the problem of direct rigidity causing damage to the roller surface.

[0053] like Figures 2 to 8 As shown, in one embodiment, the limiting assembly also includes a limiting through slot 28, which is provided on the mounting slider 10; the limiting plate 29 is inserted into the limiting through slot 28; the plug-in block 30 is slidably inserted into the end of the connecting slot 23; the arc-shaped groove rail 31 is fixedly connected to the surface of the limiting plate 29, and a connecting slider 32 is slidably arranged inside; the two ends of the gas spring 33 are respectively fixedly connected to the plug-in block 30 and the connecting slider 32; the second traction rail 34 is provided on the surface of the movable plate 22, and includes a second oblique slot 3401 and a second vertical slot 3402, and a second traction pin 35 is slidably arranged in the second oblique slot 3401, and the second traction pin 35 is fixedly connected to the surface of the plug-in block 30.

[0054] It should be understood that during the movement of the first vertical slot 2402 on the surface of the first traction pin 27, the position of the first traction pin 27 remains unchanged, and the second inclined slot 3401 passes through the second traction pin 35, so that the second traction pin 35 drives the plug-in block 30 to move, and the plug-in block 30 drives the connecting slider 32 to push the arc groove rail 31 through the gas spring 33, until the connecting slider 32 is pressed against the inner wall of the arc groove rail 31, and the arc groove rail 31 is pressed against the surface of the mounting slider 10, thereby achieving friction limitation between the connecting slider 32 and the arc groove rail 31, supporting and maintaining the adjusted guide angle of the clamping jaw 3, and then under the support of the rotating drive assembly, further increasing the support points for the guide angle of the clamping jaw 3, which is conducive to maintaining the stability of the guide angle;

[0055] It should be noted that, through the continuous pushing of the electric cylinder 21, the guide angle is further supported under the premise of maintaining the rolling of the roller 4, and the guide angle is stably maintained while the pipe pile body 36 is clamped and fixed, so as to prepare for the later adjustment of the distance between the pipe pile body 36 and the ground in the Z-axis direction and the position adjustment of the pipe pile body 36 in the X-axis direction driven by the electric slider 2;

[0056] Further explanation is that by setting the gas spring 33, during the pressing process, the gas spring 33 is pressed against the connecting slider 32 while being gradually compressed, which is helpful to avoid the problem of collision damage to the arc groove rail 31 and the connecting slider 32 caused by direct rigid collision.

[0057] like Figure 5 As shown, in one embodiment, a friction plate 37 is fixedly provided at the end of the connecting slider 32. It should be understood that by providing the friction plate 37, it is beneficial to further improve the friction coefficient of the end of the connecting slider 32, and it is beneficial to increase the friction between the end of the connecting slider 32 and the inner wall of the arc-shaped groove rail 31 when the connecting slider 32 is pressed against the inner wall of the arc-shaped groove rail 31.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
