Description

Technical Field

[0001] This invention relates to the field of auxiliary devices for foundation pile construction, specifically to a device for adjusting the verticality and preventing torsion of large-diameter steel cages. Background Technology

[0002] Large-diameter pile foundations are commonly used for anchorage foundations of large bridges in areas with good geological conditions. Meanwhile, in some wide foundation pits with poor geological conditions, pile foundations are required for ground reinforcement. In this case, rotary drilling is often used to form the hole during the construction of the pile foundation. Then, crawler cranes or truck cranes are used to lift the steel cage into the trench, and finally, concrete is poured to form the pile.

[0003] In practice, when hoisting the reinforcing cage into the trench, if it is a small-diameter reinforcing cage, its verticality can be adjusted to the correct position by twisting and swinging the upper structure. However, when it is a large-diameter reinforcing cage, due to its own structural weight, it is easy for the large-diameter reinforcing cage to tilt after being placed into the trench. It is difficult to effectively adjust the verticality to meet the design requirements by simply using ground equipment to drive the upper structure to twist and swing. Once the large-diameter reinforcing cage twists, it is also difficult to restore the reinforcing cage to its normal state through effective measures, which poses a safety hazard to the subsequent foundation reinforcement. Summary of the Invention

[0004] This application provides a verticality adjustment and anti-torsion device for large-diameter steel cages, which can solve the technical problem in the prior art that large-diameter steel cages are prone to tilting after being placed in the trench, and it is difficult to effectively adjust the verticality to meet the design requirements by simply using ground equipment to drive the upper structure to twist and swing.

[0006] An adjusting base, which is used to fix the large-diameter steel cage;

[0007] A reinforcing cage pushing component is provided on an adjusting base, and an abutment adjusting plate is provided on the telescopic end of the reinforcing cage pushing component.

[0008] And a control element for opening and closing the reinforcing cage jacking element.

[0010] In one embodiment, the control element includes:

[0011] A pneumatic pipeline is installed on the adjusting base, and the pneumatic pipeline is connected to the push cylinder and externally connected to a pressurizing device;

[0012] In addition, a pressure relief adjustment component is provided, wherein a pressure relief hole is provided on the adjustment base, the pressure relief hole is connected to the push cylinder, the pressure relief adjustment component is provided on the adjustment base and located at the opening of the pressure relief hole, and is used to open or close the pressure relief hole.

[0023] The beneficial effects of the technical solutions provided in this application include:

[0024] By installing an adjusting base on a large-diameter reinforcing cage and using a control device to activate the cage pushing mechanism, the adjusting plate on the telescopic end of the pushing mechanism extends away from the large-diameter reinforcing cage until it contacts the surface of the foundation pit outside the cage. When the large-diameter reinforcing cage tilts or twists within the foundation pit, activating the control device allows the pushing mechanism to continuously push outwards, thus adjusting and straightening the cage from the bottom of the pit. This solves the problem in existing technologies where large-diameter reinforcing cages tend to tilt after entering the pit, and relying solely on ground equipment to rotate and swing the upper structure is insufficient to effectively adjust the verticality to meet design requirements.

[0030] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0031] This application provides a verticality adjustment and anti-torsion device for large-diameter steel cages, which can solve the problem in the prior art that large-diameter steel cages are prone to tilting after being placed in the trench, and it is difficult to effectively adjust the verticality to meet the design requirements by simply using ground equipment to drive the upper structure to twist and swing.

[0032] Reference Figure 1This application discloses a verticality adjustment and anti-torsion device for large-diameter reinforcing cages, comprising an adjusting base 1, a reinforcing cage jacking component, and a control component. The adjusting base 1 is fixed to the large-diameter reinforcing cage 7. The reinforcing cage jacking component is fixed to the adjusting base 1, and an adjusting plate 21 is provided at the end of the reinforcing cage jacking component away from the adjusting base 1. The control component is used to open and close the reinforcing cage jacking component to extend or retract its telescopic end. More specifically, the adjusting base 1 is made of steel, which has high tensile, compressive, bending, and shear strengths. Using steel to make the adjusting base 1 can extend its service life, eliminating the need for frequent replacements and making it more convenient to use.

[0033] During the installation of the large-diameter reinforcing cage 7, the adjusting base 1 is first fixed to the surface of the large-diameter reinforcing cage 7, specifically by welding, to ensure a more secure fixation and reduce the possibility of the adjusting base 1 falling off the surface of the large-diameter reinforcing cage 7 during adjustment. The operating position of the control unit extends to the ground, allowing operators to open or close the reinforcing cage jacking component from the ground. When the operator detects tilting or twisting at the bottom of the large-diameter reinforcing cage 7 using the detection equipment on the ground, the operator opens the reinforcing cage jacking component through the control unit, causing the telescopic end of the reinforcing cage jacking component to extend. This moves the abutment adjusting plate 21 away from the end of the large-diameter reinforcing cage 7, bringing the abutment adjusting plate 21 into contact with the surface of the foundation pit. The telescopic end of the reinforcing cage jacking component continues to push outward, thereby adjusting and straightening the position of the large-diameter reinforcing cage 7 from the bottom of the foundation pit. To facilitate operators in adjusting the position of the large-diameter steel cage 7, multiple verticality adjustment and anti-torsion devices can be installed on the bottom surface of the large-diameter steel cage 7. This allows operators to adjust and straighten the large-diameter steel cage 7 in multiple directions, solving the problem in the existing technology where the large-diameter steel cage 7 tends to tilt after being placed in the trench, and it is difficult to effectively adjust the verticality to meet the design requirements by simply using ground equipment to drive the upper structure to twist and swing.

[0034] In one embodiment of this application, reference is made to Figure 2 and Figure 3The jacking component for the reinforcing cage is specifically a jacking cylinder 2, which is bolted to the adjusting base 1. The control components include a pneumatic pipeline 3 and a pressure relief adjustment assembly. The pneumatic pipeline 3 is also bolted to the adjusting base 1 and is connected to the jacking cylinder 2. The pneumatic pipeline 3 extends to the ground and is connected to external pressurization equipment, allowing operators to supply gas to the pneumatic pipeline 3 from the ground, thereby increasing the air pressure inside the jacking cylinder 2 and causing its extension end to extend outwards. A pressure relief hole 4 is provided on the adjusting base 1, connected to the jacking cylinder 2 for pressure relief operations. The pressure relief adjustment assembly is located on the adjusting base 1 at the opening of the pressure relief hole 4, allowing operators to switch the opening or closing state of the pressure relief hole 4 using the assembly.

[0035] In one embodiment of this application, the pressure relief adjustment assembly includes a sealing plate 5 and a traction rope 51. The sealing plate 5 is slidably disposed at the pressure relief hole 4 on the adjustment base 1. The area of ​​the sealing plate 5 is larger than the area of ​​the pressure relief hole 4, thereby allowing the sealing plate 5 to switch between the open and closed states of the pressure relief hole 4 by sliding its position. The traction rope 51 is disposed on the sealing plate 5 and extends upward to the outside of the pit, so that the operator can pull the traction rope 51 to adjust the sealing and pressure relief states of the pressure relief hole 4. In the initial state, the sealing plate 5 is covered on the pressure relief hole 4 due to its own weight, and the pressure relief hole 4 is in a sealed state. When the operator needs to perform a pressure relief operation on the push cylinder 2, the traction rope 51 is pulled to lift the sealing plate 5 upward, causing the telescopic end of the push cylinder 2 to retract, and the pressure relief hole 4 to communicate with the outside, thereby realizing the pressure relief operation on the push cylinder 2.

[0036] More specifically, in this embodiment, the pressure relief regulating assembly further includes a limiting slide groove 6, which is welded to the regulating base 1. The size of the limiting slide groove 6 is adapted to the thickness of the sealing plate 5, and the sealing plate 5 is slidably disposed within the limiting slide groove 6. Specifically, the limiting slide groove 6 is configured as a square groove without openings. The limiting slide groove 6 surrounds the pressure relief hole 4 within the limiting slide groove 6, facilitating the sliding of the sealing plate 5. In the initial state, when the sealing plate 5 is located at the bottom of the limiting slide groove 6, the limiting slide groove 6 can limit the position of the sealing plate 5, so that the sealing plate 5 blocks the pressure relief hole 4, thereby making the pressure relief hole 4 in a sealed state.

[0037] Furthermore, since the air pressure inside the push cylinder 2 is relatively high when the air pressure pipeline replenishes the air pressure inside the push cylinder 2, in order to reduce the impact of the pressure inside the push cylinder 2 on the sealing plate 5 and prevent it from moving within the limit slide groove 6 and causing air leakage in the pressure relief hole 4, a reset component is also provided on the sealing plate 5. The reset component can pull the sealing plate 5 back to the initial state of sealing the pressure relief hole 4.

[0038] In one embodiment of this application, the reset component is specifically configured as a reset spring 61. The two ends of the reset spring 61 are respectively connected to a limiting groove 6 and a sealing plate 5, and the reset spring 61 is located at the bottom of the limiting groove 6. When the reset spring 61 is in its initial compressed state, the sealing plate 5 is located at the bottom of the limiting groove 6 and seals the pressure relief hole 4. When the operator pulls the traction rope 51, the sealing plate 5 slides upward within the limiting groove 6, the reset spring 61 extends, and the pressure relief hole 4 communicates with the outside. When the operator releases the traction rope 51, the reset spring 61 pulls the sealing plate 5 back to the bottom of the limiting groove 6, sealing the pressure relief hole 4. The structure is simple and easy to use.

[0039] More specifically, a connecting buckle 52 is welded onto the sealing plate 5, and the traction rope 51 is threaded through the connecting buckle 52 to make the fixation of the traction rope 51 more stable. In one embodiment of this application, the traction rope 51 is specifically made of steel strand, which is a steel product composed of multiple steel wires twisted together. It has the characteristics of high strength, corrosion resistance, and fatigue resistance, which can extend the service life of the traction rope 51 and reduce the possibility of the traction rope 51 breaking when the operator pulls it.
