[0042] The steel cage lowering device of the utility model embodiment is provided with a plurality of cushion beam assemblies, a plurality of connecting blocks and a plurality of fixing assemblies. The plurality of cushion beam assemblies are arranged at intervals in a ring shape, and a connecting block is arranged between every two of the cushion beam assemblies and is detachably connected thereto. The connecting blocks have different specifications. By selecting the connecting blocks of different length specifications to be connected to the cushion beam assemblies, the annular diameters of the plurality of cushion beam assemblies are adjusted so that the annular diameters formed by the plurality of cushion beam assemblies match the diameter of the steel cage to be lowered, and then the steel cage is fixed by the fixing assembly. Therefore, the steel cage lowering device of the utility model can be applied to steel cages of various different diameters, and there is no need to process steel cage lowering devices of different diameters, thereby improving the utilization rate of the construction site and reducing the construction cost.

[0043] As an optional implementation, in a utility model embodiment, see Figure 2 As shown, each of the pad beam assemblies 1 includes: a first pad beam 11 and a second pad beam 12, one end of the first pad beam 11 is detachably connected to one of the connecting blocks 2, one end of the second pad beam 12 is fixedly connected to the other end of the first pad beam 11, and the other end of the second pad beam 12 is detachably connected to another connecting block 2, the first pad beam 11 is vertically fixed to the second pad beam 12, that is, the other end of the first pad beam 11 is fixedly connected to one end of the second pad beam 12 by welding, one end of the first pad beam 11 and the other end of the second pad beam 12 are both detachably connected to the connecting block 2, that is, after the connecting block 2 is removed, the multiple pad beam assemblies 1 are also disassembled into multiple component modules, which are convenient for moving to the next pile foundation hole for construction and can be recycled, saving construction materials and construction costs.

[0044] As an optional implementation, in a utility model embodiment, see Figure 4 and Figure 5 As shown, the steel cage lowering device also includes: multiple connecting plates 4, each of the two ends of the cushion beam assembly 1 is correspondingly provided with the connecting plates 4, and each of the two ends of the connecting block 2 is also correspondingly provided with the connecting plates 4, and the connecting plates 4 are used to detachably connect the cushion beam assembly 1 with the connecting block 2. Since each of the cushion beam assembly 1 and the connecting block 2 are made of I-beam material, their cross-sectional shape is I-shaped, and the two surfaces of the flanges are parallel to each other, which makes connection, processing and installation simple. The connecting plates 4 are arranged on both sides of each of the cushion beam assembly 1 and both sides of each of the connecting blocks 2, and the cushion beam assembly 1 is connected to the connecting block 2 through the connecting plates 4, and the connecting plates 4 are easy to process, and the installation and disassembly operations are simple.

[0045] As an optional implementation, in a utility model embodiment, see Figure 4 and Figure 5 As shown, each of the connecting plates 4 is provided with a plurality of bolt holes 41 at intervals in the vertical direction, and the plurality of bolt holes 41 are used to connect with adjustable bolts 42. The connecting plates 4 on the pad beam assembly 1 and the connecting plates 4 on the connecting block 2 are both provided with a plurality of bolt holes 41. When the pad beam assembly 1 is connected to the connecting block 2, the adjustable bolts 42 are passed through the bolt holes 41 and fixedly connected. The connecting block 2 with a shorter length can be removed by the adjustable bolts 42 and replaced with the connecting block 2 with a longer installation length, so as to adjust the length of the pad beam assembly 1, and then adjust the diameter of the ring surrounded by the plurality of pad beam assemblies 1. At the same time, the length of the pad beam assembly 1 can also be fine-tuned by adjusting the connection length between the pad beam assembly 1 and the connecting block 2 by the adjustable bolts 42.

[0046] As an optional implementation, in a utility model embodiment, see Figure 5 As shown, each of the connecting plates 4 is fixedly connected to the cushion beam assembly 1 and the connecting block 2 by welding. The welding fixing method has a simple structure, easy operation, high joint strength, good density, metal saving, high productivity and low cost.

[0047] As an optional implementation, in a utility model embodiment, see Figure 2 and Figure 3 As shown, each of the fixing components 3 includes: an oblique connection block 31, a stopper 32 and a clamping plate 33, one end of the oblique connection block 31 is fixedly connected to the first cushion beam 11, and the other end is fixedly connected to the second cushion beam 12, the stopper 32 is arranged above the oblique connection block 31, the clamping plate 33 is arranged above the oblique connection block 31, and one end of the clamping plate 33 is inserted and fixed in the stopper 32, and the other end is used to connect the steel cage 5, one end of the clamping plate 33 is fixedly connected to the stopper 32, and the other end extends to the center of the pile foundation hole and passes through the steel cage 5 to fix the steel cage 5, and the steel cage 5 is circumferentially A plurality of U-shaped steel bars with openings downward are welded, and each U-shaped steel bar is welded and fixed to two main bars adjacent to the steel cage 5. The clamping plate 33 passes through the U-shaped steel bar to fix the steel cage 5 at the opening of the pile foundation. By using the U-shaped steel bar, the clamping plate 33 is avoided from being directly connected to the stirrups of the steel cage 5 to cause deformation, thereby ensuring the quality and structural stability of the steel cage 5. The oblique connecting block 31 and the clamping plate 33 are located at different positions of the ring surrounded by the plurality of cushion beam assemblies 1, so that the clamping plate 33 fixes the steel cage 5 from multiple directions respectively, so that the steel cage 5 is subjected to uniform force, which facilitates better fixing of the steel cage 5.

[0048] As an optional implementation, in a utility model embodiment, see Figure 3As shown, the clamping plate 33 is a rectangular parallelepiped structure, and a square through hole 321 matching the size of the clamping plate 33 is provided in the limiter 32. One end of the clamping plate 33 passes through the square through hole 321 and is pin-connected to the limiter 32. By setting the square through hole 321, the clamping plate 33 can pass through the limiter 32 and slide along its length direction. When the diameter of the ring surrounded by the multiple cushion beam assemblies 1 becomes larger, the distance between the clamping plate 33 and the center position of the pile foundation hole becomes larger. At this time, the clamping plate 33 is slid along the length direction of the limiter 32 toward the center position of the pile foundation hole, so as to extend the length of the clamping plate 33. When the diameter of the ring surrounded by the multiple cushion beam assemblies 1 becomes smaller, the distance between the clamping plate 33 and the center position of the pile foundation hole becomes smaller. At this time, the clamping plate 33 is slid along the length direction of the limiter 32 away from the center position of the pile foundation hole, so as to shorten the length of the clamping plate 33. Therefore, the utility model can fix steel cages of various diameters, thereby improving the utilization rate of the utility model.

The second adjustment hole 331 cooperates with the first adjustment hole 322 to adjust the length of the card plate 33. The size of the second adjustment hole 331 matches the size of the first adjustment hole 322, and both are through holes of the same diameter. When the length of the card plate 33 needs to be extended, the second adjustment hole 331 at the rear end of the card plate 33 is overlapped with the first adjustment hole 322, and a cylindrical pin is used to penetrate the second adjustment hole 331 and the first adjustment hole 322 to fix the current position of the card plate 33. When the length of the card plate 33 needs to be shortened, the second adjustment hole 331 at the front end of the card plate 33 is overlapped with the first adjustment hole 322, and a cylindrical pin is used to penetrate the second adjustment hole 331 and the first adjustment hole 322 to fix the current position of the card plate 33. Through this connection method, the length adjustment of the card plate 33 is simple.

[0050] As an optional implementation, in a utility model embodiment, see Figure 6 As shown, the other end of the clamping plate 33 is also provided with a barb 332 for preventing the steel cage 5 from tipping over. When the steel cage 5 is offset, the barb 332 can clamp the steel cage 5 and fix it to the hole of the pile foundation, effectively preventing the steel cage 5 from tipping over or falling into the hole of the pile foundation.

[0051] As an optional implementation, in a utility model embodiment, see Figure 1As shown, the plurality of cushion beam assemblies 1, the plurality of connecting blocks 2, the plurality of fixing assemblies 3 and the plurality of connecting plates 4 are all made of steel.
