Description

Technical Field

[0001] The present application relates to the technical field of pile foundation construction, and in particular to a 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 the smooth formation of piles and the quality of pile foundation construction, the verticality of the steel sheet piles needs to be strictly controlled during the piling process to ensure that the driven steel sheet piles can meet the construction specifications.

[0003] In the prior art, during piling construction at a dock, a crane is usually used to hoist and transport steel sheet piles to a specified position, and then the steel sheet piles are positioned by a positioning frame, so that it is convenient for the pile hammer to drive the steel sheet piles into the silt layer for fixation. However, during the hoisting and transportation of the steel sheet piles, due to the large size of the steel sheet piles themselves, the lower end of the steel sheet piles is prone to shaking and tilting when the steel sheet piles are transported to the positioning frame. Therefore, it is usually necessary to manually support the lower end of the steel sheet pile and adjust the position to ensure that the verticality of the steel sheet piles meets the standard after piling and fixation.

[0004] However, the method of manually supporting and adjusting the verticality of the steel sheet piles requires high labor costs, and it is more difficult to adjust the verticality. In addition, due to the large size of the steel sheet piles, the workers mainly rely on experience to judge the verticality of the steel sheet piles when adjusting the verticality of the steel sheet piles. It is easy to make mistakes in judgment, resulting in the verticality of the steel sheet piles not meeting the construction specifications and requiring re-piling, thereby affecting the construction efficiency. It is inconvenient to use. Utility Model Content

[0005] In order to guide and position steel sheet piles during transportation, ensure that the verticality is up to standard during piling, and thus improve construction efficiency, the present application provides a positioning frame for dock piling.

During the descent of the steel sheet pile, the steel sheet pile is guided by the guide assembly so that the bottom end of the steel sheet pile enters the guide groove. Then, the steel sheet pile is corrected by the correction assembly so that during the descent of the steel sheet pile, it is always in a vertical state before the bottom end of the steel sheet pile touches the ground. After that, the steel sheet pile can be driven into the ground by a pile hammer to achieve piling. After the first steel sheet pile is driven down, the sliding seat can be driven to slide to the specified position by the driving assembly, and the above steps can be repeated to achieve multiple piling. The overall use is simple and convenient, which reduces labor costs and improves work efficiency.

After sliding to the specified position, the first driving member drives the two clamping plates to slide towards each other, so that the clamping plate is clamped on the steel sheet pile, and the verticality of the steel sheet pile is corrected by the abutment block, thereby ensuring that the steel sheet pile is in a vertical state when the pile hammer hits the steel sheet pile.

[0017] Preferably, the first driving member is a bidirectional electric cylinder, a cylinder body of the bidirectional electric cylinder is mounted on the sliding seat, and two piston rods of the bidirectional electric cylinder are respectively fixedly connected to one of the fixed blocks.

[0018] By adopting the above technical solution, the two fixed blocks are synchronously driven to slide by the bidirectional electric cylinder during use, thereby driving the two clamping plates to slide towards each other, so as to achieve the clamping and fixing of the steel sheet piles.

[0026] 1. When in use, the steel sheet pile is hoisted and transported to the top of the guide groove. Under the action of the guide component, the steel sheet pile slides into the guide groove. At the same time, the steel sheet pile is corrected for verticality by the correction component to ensure that the steel sheet pile remains vertical when it contacts the ground. At the same time, when the pile hammer is used to drive the steel sheet pile, the clamping limit of the correction component is used to prevent the steel sheet pile from being skewed when it is hit by external force, so as to ensure the quality of piling. After that, the driving component drives the sliding seat to change its position, which is convenient for subsequent piling. The overall use is automated, which reduces the tediousness of manual work and improves work efficiency.

[0043] Reference Figure 1 and Figure 4 When in use, the steel sheet pile 9 is transported to the top of the installation frame 1 by hoisting. When the steel sheet pile 9 falls, it first passes through the avoidance groove 31 and then slides into the guide groove 2 under the guidance of the inclined surface of the guide plate 41. During the falling process of the steel sheet pile 9, the avoidance groove 31 is used to preliminarily limit the falling range of the steel sheet pile 9 to ensure that the steel sheet pile 9 can fall into the guide groove 2.

[0044] Reference Figure 4 and Figure 5A correction component 5 is provided on the sliding seat 3, and the correction component 5 is used to correct the verticality of the steel sheet pile 9 during the falling process. The correction component 5 is located on the first frame 11, and the correction component 5 includes two fixed blocks 51, a first driving member 52, two clamping plates 53, an abutment block 54 and a second driving member 55.

The two piston rods of the electric cylinder are respectively fixedly connected to a fixed block 51; when in use, the two piston rods of the bidirectional electric cylinder 521 are synchronously extended and retracted to realize the synchronous sliding of the two fixed blocks 51.

[0045] Reference Figure 5 and Figure 6 The clamping plate 53 slides on the fixed block 51 along the width direction of the mounting frame 1, and the abutment block 54 is welded to one end of the clamping plate 53 close to the steel sheet pile 9.

The first driving member 52 is an electric push cylinder 551, and the cylinder body of the electric push cylinder 551 is fixedly connected to the fixed block 51, and the piston rod of the second electric push cylinder 551 is fixedly connected to the clamping plate 53; when in use, the clamping plate 53 is driven to slide close to the steel sheet pile 9 by the extension and contraction of the piston rod of the electric push cylinder 551. When the inclined surface on the abutment block 54 is facing the side wall of the steel sheet pile 9, the two clamping plates 53 are driven to slide toward each other by the two-way electric cylinder 521, so as to clamp the steel sheet pile 9. At this time, the abutment block 54 can abut the steel sheet pile 9 to ensure that the steel sheet pile 9 is in a vertical state.

At this time, the side wall of the limit plate 42 abuts against the side wall of the steel sheet pile 9 to ensure that the steel sheet pile 9 is located in the middle position of the mounting frame 1. When the steel sheet pile 9 descends into the guide groove 2, the two clamping plates 53 are driven to slide synchronously by the electric push cylinder 551, so that the abutment block 54 faces the steel sheet pile. 9, and then the two clamping plates 53 are driven to slide towards each other through the two-way electric cylinder 521 to clamp the steel sheet pile 9, so as to ensure the verticality of the steel sheet pile 9 when it is lowered, and then the steel sheet pile 9 is piled by the pile hammer. After completing the piling operation of the first steel sheet pile 9, the screw 61 is driven to rotate by the driving motor 63, and the rotation of the screw 61 drives the sliding seat 3 to slide. At the same time, the staff observes the shooting picture transmitted by the camera 8 through the display device, and judges the sliding distance of the sliding seat 3 according to the numerical change of the scale line 71 in the shooting picture, so as to accurately control the distance between two adjacent steel sheet piles 9, so as to improve the quality of the pile foundation after piling. It is simple and convenient to use, and the operation process is automated, which reduces labor costs and improves construction efficiency.
