Description

Technical Field

[0001] The present application relates to the technical field of pile foundation construction, and in particular to a mobile positioning frame for dock piling. Background Art

[0002] In dock construction, it is usually necessary to drive steel sheet piles into the mud layer on the shore and build buildings on the steel sheet piles. In order to ensure smooth pile formation and the quality of pile foundation construction, it is necessary to ensure that the driven steel sheet piles are distributed along a straight line during the piling process.

[0003] In the prior art, when piling is carried out at a wharf, a crane is usually used to hoist and transport the pile frame to a designated location, and then the steel sheet piles are hoisted and transported. During the falling of the steel sheet piles, construction workers are required to stand on the pile frame and manually guide the bottom end of the steel sheet pile until the steel sheet pile enters the guide space in the middle of the pile frame. At the same time, during the falling and piling process of the steel sheet piles, the construction workers also need to ensure the verticality of the steel sheet piles to ensure the quality of the construction.

[0004] The overall length of the pile driver in the prior art is not sufficient to support the number of steel sheet piles that need to be driven, and can usually only meet a certain number of pile driving operations. Therefore, after completing a certain number of pile driving operations each time, the construction workers are required to manually pull the pile driver with a cable to move the pile driver to the next pile driving location. However, in actual use, since the construction site is located in the silt layer on the shore of the dock, the silt layer itself has a soft structure and an unstable force direction. Manual pulling to move the pile driver usually requires the cooperation of multiple people, and the overall moving process is time-consuming and labor-intensive. In addition, the moving direction is prone to deviate from the piling direction during the moving process, which is inconvenient to use. Utility Model Content

[0005] In order to achieve the purpose of conveniently moving the pile driving frame after completing the piling operation and avoiding deviation of the moving direction of the pile driving frame, the present application provides a mobile positioning frame for dock piling.

[0006] The present application provides a mobile positioning frame for dock piling, which adopts the following technical solution:

[0008] By adopting the above technical solution, when in use, the pile frame is transported to the position where piling is required by the lifting equipment, and then the steel sheet pile is transported to the top of the pile frame by the lifting equipment. During the descent of the steel sheet pile, the construction personnel stand on the pile frame to guide the steel sheet pile so that the bottom end of the steel sheet pile enters the guide groove. After that, the verticality of the steel sheet pile is manually corrected when the steel sheet pile is driven, so as to ensure the quality of the pile foundation. When a certain number of steel sheet piles are driven, that is, when there is no extra space in the guide groove for the next steel sheet pile to be inserted, the pile foundation that has been driven is clamped by the clamping assembly. , and then positioned by the positioning assembly, and then the sliding seat is driven to slide by the first driving assembly. Since the sliding seat has been fixed in position under the clamping action of the clamping assembly, the first driving assembly reversely drives the pile driver to slide along its own length direction, thereby realizing the movement of the pile driver in the piling direction. When the pile driver moves to the specified position, the clamping assembly releases the pile foundation, and the positioning assembly returns to its original position. After that, the first driving assembly drives the sliding seat to reset, thereby realizing the movement of the entire pile driver. It is simple and convenient to use. At the same time, the tank chain adopts a crawler tank chain to ensure that the traveling direction of the pile driver will not be easily deviated.

[0009] Preferably, the piling frame includes a first frame body and a second frame body which are arranged opposite to each other, a connecting frame for connecting the first frame body and the second frame body, and a fixing plate fixed to the first frame body and the second frame body, the first frame body and the second frame body are respectively located on both sides of the steel sheet pile, the connecting frame is located at one end of the first frame body and the second frame body, the guide groove is formed between the first frame body, the second frame body and the connecting frame, and the sliding seat slides on the fixing plate.

[0010] By adopting the above technical solution, when the steel sheet piles fall into the guide groove during use, the first frame and the second frame clamp and position the steel sheet piles, ensuring that the positions of the multiple steel sheet piles driven in remain in the same straight line, thereby ensuring that the quality of construction meets the standards. At the same time, when the pile frame moves, the first frame and the second frame can also be limited by the driven pile foundation to ensure that the moving direction of the pile frame is consistent with the piling direction.

[0011] Preferably, an avoidance groove is provided on the sliding seat, and the avoidance groove is communicated with the guide groove.

[0012] By adopting the above technical solution, an avoidance groove is provided during use to prevent the sliding seat from affecting the steel sheet pile from falling and inserting into the guide groove, while ensuring that the clamping assembly installed on the sliding seat can be used normally.

[0013] Preferably, the clamping assembly comprises two clamping plates sliding on the sliding seat, the two clamping plates are arranged opposite to each other, and the sliding seat is provided with a second driving assembly for driving the two clamping plates to slide towards each other.

[0014] By adopting the above technical solution, the two clamping plates are driven to move toward each other by the second driving component during use, thereby clamping the steel sheet piles, and the sliding seat is fixed by the friction force between the clamping plates and the steel sheet piles.

[0015] Preferably, the second driving assembly includes a bidirectional screw that rotates on the sliding seat and a driving motor that is fixed on the sliding seat. The two clamps are respectively threadedly connected to one side of the bidirectional screw, and the main shaft of the driving motor is coaxially fixedly connected to the bidirectional screw.

[0016] By adopting the above technical solution, the bidirectional screw is driven to rotate by rotating the main shaft of the driving motor during use. Since the bolts on both sides of the bidirectional screw rotate in opposite directions, the clamping plates threadedly connected on both sides of the bidirectional screw slide when the bidirectional screw rotates, so that the two clamping plates are close to each other, thereby clamping the steel sheet piles.

[0017] Preferably, the first driving assembly comprises a mounting seat fixedly connected to the pile driver frame, a hydraulic cylinder fixed to the mounting seat, a cylinder body of the hydraulic cylinder fixedly connected to the mounting seat, and a piston rod of the hydraulic cylinder fixedly connected to the sliding seat.

[0019] Preferably, the positioning assembly includes a support column that slides along the height direction of the pile driver and a plug connector fixed at the bottom end of the support column, the support column is located at one end of the sliding seat, the plug connector is conical in shape, and the tip of the plug connector faces the ground, and the sliding seat is provided with a clamping structure for clamping the support column.

[0020] By adopting the above technical solution, when the positioning component needs to be positioned during use, the construction personnel open the clamping structure, and the support column can be made to fall under the action of gravity, and the plug connector of the support column is inserted into the soil layer to achieve positioning.

When the support column needs to be retracted, the support column can be fixed by lifting the support column and reinserting the pin into the socket. The use is simple and convenient.

[0023] Preferably, a ladder is installed on the pile driving frame, and a guardrail is provided on the pile driving frame.

[0024] By adopting the above technical solution, a ladder is provided to facilitate construction workers to go up and down the pile driving frame during use, and a guardrail is provided to provide simple protection for the pile driving frame, thereby improving the safety of use.

[0026] 1. When in use, the steel sheet pile is hoisted and transported to the top of the guide groove, and the construction personnel guide the lower end of the steel sheet pile so that the steel sheet pile slides into the guide groove. At the same time, during the piling process, the verticality of the steel sheet pile is manually corrected to prevent the steel sheet pile from being skewed when hit by external force, so as to ensure the quality of piling. When the pile driving frame needs to be moved, the pile foundation is clamped by the clamping assembly to realize the fixed sliding seat, so as to realize the reverse sliding of the pile driving frame through the extension and retraction of the piston rod of the hydraulic cylinder. When the pile driving frame moves to the specified position, the clamping assembly releases the pile foundation, and then the sliding seat is driven to reset by the piston rod of the hydraulic cylinder, so as to realize the mobile pile driving frame, which is convenient for subsequent piling. The overall use is simple and convenient, which reduces the tediousness of manual work and ensures that the moving direction of the pile driving frame does not deviate.

DETAILED DESCRIPTION

[0038] The following is combined with Figure 1 -Attached Figure 8 This application is described in further detail.

[0039] The embodiment of the present application discloses a mobile positioning frame for dock piling.

[0040] Reference Figure 1 and Figure 2A mobile positioning frame for dock piling includes a piling frame 1 placed horizontally on the ground, the piling frame 1 includes a first frame body 11, a second frame body 12, a connecting frame 13 and a fixing plate 14, the first frame body 11 and the second frame body 12 are arranged opposite to each other, and the first frame body 11 and the second frame body 12 are respectively located on both sides of a steel sheet pile 30, the connecting frame 13 is arranged at the ends of the first frame body 11 and the second frame body 12, and the connecting frame 13 is used to connect and fix the first frame body 11 and the second frame body 12 together, and a hole with an open end is formed between the first frame body 11, the second frame body 12 and the connecting frame 13 The guide groove 2 and the fixing plate 14 are arranged above the first frame 11 and the second frame 12, and the first frame 11 and the second frame 12 are fixedly connected to the fixing plate 14, and the first frame 11 and the second frame 12 are welded with lifting ears 40; when in use, the lifting ears 40 are used to facilitate the lifting and transportation of the pile frame 1 to the designated piling position, and then the steel sheet piles 30 are guided and limited by the guide groove 2 to ensure that the steel sheet piles 30 land at the designated piling position, and at the same time, the first frame 11 and the second frame 12 are limited by the driven steel sheet piles 30 to ensure that the driven steel sheet piles 30 remain in the same straight line.

[0041] Reference Figure 1 A tank chain 9 is installed at the bottom end of the pile frame 1. When in use, the tank chain 9 drives the pile frame 1 to move. On the one hand, since the construction site is located on the port shore, the use of the tank chain 9 can ensure the normal movement of the pile frame 1. On the other hand, the movement of the pile frame by the tank chain 9 is conducive to avoiding the problem that the moving direction of the pile frame 1 deviates from the piling direction due to poor ground support when the pile frame 1 moves.

[0042] Reference Figure 1 and Figure 2 Since the construction workers need to stand on the fixed plate 14 to guide the bottom end of the steel sheet pile 30 into the guide groove 2 during the process of hoisting the steel sheet pile 30, a ladder 10 is detachably connected to the pile frame 1 to facilitate the construction workers to get on and off the pile frame 1. At the same time, a guardrail 20 is also provided on the fixed plate 14 to increase the safety of the construction workers standing on the fixed plate 14, making it more convenient to use.

[0043] Reference Figure 1 and Figure 3The fixed plate 14 is slidably connected with a sliding seat 3, and an avoidance groove 31 is provided on the sliding seat 3. The sliding seat 3 is located above the guide groove 2, and the avoidance groove 31 is connected to the guide groove 2. A clamping assembly 4 is provided on the sliding seat 3, and the clamping assembly 4 is used to clamp the pile foundation. The first frame 11 and the second frame 12 are both equipped with a first driving assembly 5, and the first driving assembly 5 is used to drive the sliding seat 3 to slide; when in use, the avoidance groove 31 is used to prevent the sliding seat 3 from affecting the falling of the steel sheet pile 30. When a certain number of steel sheet piles 30 are driven, Afterwards, the pile foundation is clamped by the clamping assembly 4, so as to fix the sliding seat 3, and then the two groups of first driving assemblies 5 work together to drive the pile frame 1 to slide along the length direction of the pile frame 1, so that the sliding seat 3 and the pile frame 1 are misaligned with each other. When the pile frame 1 moves to the specified position, the clamping assembly 4 is driven to release the pile foundation, and then the sliding seat 3 can be driven to reset by the first driving assembly 5, so as to realize the movement of the pile frame 1, and at the same time ensure that the moving direction of the pile frame 1 is consistent with the piling direction.

[0044] Reference Figure 3 and Figure 4 The first driving assembly 5 is located below the fixed plate 14. The first driving assembly 5 includes a mounting seat 51 and a hydraulic cylinder 52. The mounting seat 51 is fixedly connected to the pile driving frame 1. The cylinder body of the hydraulic cylinder 52 is installed on the mounting seat 51. The piston rod of the hydraulic cylinder 52 is fixedly connected to the sliding seat 3. When in use, when the clamping assembly 4 clamps the pile foundation, the piston rod of the hydraulic cylinder 52 extends in the reverse direction to drive the pile driving frame 1 to move. When the clamping assembly 4 releases the pile foundation, the piston rod of the hydraulic cylinder 52 retracts, and at the same time drives the sliding seat 3 to reset.

[0045] Reference Figure 1 and Figure 5 The clamping assembly 4 includes two clamping plates 41 which are arranged opposite to each other. The two clamping plates 41 are respectively located on both sides of the steel sheet pile 30, and the two clamping plates 41 are both slidably connected to the sliding seat 3. The sliding seat 3 is provided with a second driving assembly 7, and the second driving assembly 7 is used to drive the two clamping plates 41 to move closer to or away from each other, so as to clamp the pile foundation; when in use, the two clamping plates 41 are driven closer to each other by the second driving assembly 7 until the two clamping plates 41 are both in contact with the side walls of the pile foundation, so as to clamp the pile foundation, thereby facilitating the movement of the pile driving frame 1; when the second driving assembly 7 drives the two clamping plates 41 to move away from each other, the pile foundation is released, so as to facilitate the resetting of the sliding seat 3.

[0046] Reference Figure 3 and Figure 6The second driving assembly 7 includes a bidirectional screw rod 71 and a driving motor 72. The bidirectional screw rod 71 is rotatably connected to the sliding seat 3. The two clamping plates 41 are respectively threadedly connected to one side of the bidirectional screw rod 71. The driving motor 72 is fixedly connected to the sliding seat 3. The main shaft of the driving motor 72 is coaxially fixedly connected to the bidirectional screw rod 71. The second driving assembly 7 is located at one end of the sliding seat 3 as a whole. When in use, the main shaft of the driving motor 72 rotates to drive the bidirectional screw rod 71 to rotate. Since the threads on both sides of the bidirectional screw rod 71 have opposite rotation directions, the two clamping plates 41 connected on both sides of the bidirectional screw rod 71 are close to each other under the rotation of the bidirectional screw rod 71, thereby clamping the driven steel sheet piles 30.

[0047] Reference Figure 3 and Figure 7 A positioning assembly 6 is provided on the sliding seat 3, and the positioning assembly 6 is used to position the sliding seat 3 after movement. The positioning assembly 6 is located on the sliding seat 3 at one end away from the second driving assembly 7. The positioning assembly 6 includes a support column 61 and a plug connector 62. The support column 61 slides on the sliding seat 3, and the sliding direction of the support column 61 is a vertical direction. The plug connector 62 is integrally formed at the bottom end of the support column 61. The plug connector 62 is conical as a whole, and the tip of the plug connector 62 is vertically downward; when in use, under the action of gravity, the support column 61 falls, so that the plug connector 62 is inserted into the ground, thereby fixing the support column 61, and then supporting the sliding seat 3 through the support column 61, so as to ensure the stability of the sliding seat 3 and the pile driver 1 after separation.

[0048] Reference Figure 7 and Figure 8 A clamping structure 8 is provided on the sliding seat 3, and the clamping structure 8 is used to clamp the support column 61 to prevent the support column 61 from sliding. The clamping structure 8 includes a latch 81, and the latch 81 slides on the sliding seat 3. A corresponding plug hole 82 is opened on the support column 61; when in use, when one end of the latch 81 is inserted into the plug hole 82, the support column 61 can be limited by the latch 81 to prevent the support column 61 from sliding down, and at this time, the plug connector 62 on the support column 61 is separated from the ground, thereby preventing the film and television sliding seat 3 from resetting.

[0049] The implementation principle of the embodiment of the present application is as follows: when in use, the pile frame 1 is transported to the piling position by hoisting, and then the construction personnel climb up the pile frame 1 by the ladder 10 to assist in the transportation of the steel sheet pile 30. When the steel sheet pile 30 is hoisted and transported, the construction personnel guide the bottom end of the steel sheet pile 30 so that the steel sheet pile 30 falls into the guide groove 2. Then, during the piling process, the verticality of the steel sheet pile 30 is corrected to ensure the quality of the pile foundation. When the steel sheet piles 30 in the guide groove 2 meet a certain number, that is, the number of steel sheet piles 30 driven in this embodiment is preferably 7 to 9, the bidirectional screw rod 71 can be driven to rotate by the driving motor 72 to drive the two The clamping plates 41 are close to each other to clamp the steel sheet pile 30. At the same time, the construction personnel pull out the pin 81, so that the support column 61 falls and the plug connector 62 is inserted into the ground to limit the sliding seat 3. Then, the hydraulic cylinder 52 is used to drive the pile frame 1 forward in the reverse direction. When it moves to the specified position, the construction personnel first lift the support column 61 and reinsert the pin 81 into the socket 82. Then, the driving motor 72 drives the clamping plate 41 to disengage from the steel sheet pile 30. Then, the piston rod of the hydraulic cylinder 52 is retracted to drive the sliding seat 3 to reset, thereby realizing the convenient movement of the pile frame 1 and ensuring that the moving direction of the pile frame 1 is consistent with the direction of piling.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
