Description

Technical Field

[0001] This invention relates to the field of underwater foundation construction technology, and in particular to an auxiliary construction device for rapid construction of deep-water submerged concrete foundations. Background Technology

[0002] A steel caisson is a formwork used in the construction of bridge pier foundations in underwater conditions. Because underwater pier foundations are generally large and must withstand water pressure, steel caissons are typically made of steel plates and structural steel reinforced with steel. Large-tonnage truck cranes or crawler cranes are usually used for lifting. The steel caisson formwork is typically transported to the work site via lifting equipment on a steel trestle platform or on a transport ship. Then, the entire steel caisson formwork is assembled. After assembly, a temporary support system is installed, and the steel caisson formwork is lowered to its designed position.

[0003] During the construction of steel caisson foundations, before pouring the foundation concrete, it is necessary to break up the concrete at the pile heads extending into the foundation and bend the pre-reserved pile foundation reinforcement bars in all directions to facilitate binding and pouring with the subsequent foundation reinforcement bars to form a unified structure. Currently, bending is generally done manually; however, small bending machines are inconvenient to operate and prone to reinforcement bar rebound, leading to safety hazards. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies and propose a rapid construction auxiliary equipment for deep-water immersion concrete foundation construction, which solves the problems of inconvenience in manually operating small bending machines, easy rebound of reinforcing bars, and safety issues in existing technologies.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rapid construction auxiliary device for deep-water submerged concrete foundations includes a horizontal plate, a support column rotatably connected to the horizontal plate, a bending rod hinged to the lower end of the support column, a thrust device hinged to the outer side of the support column, and the thrust device hinged to the bending rod.

[0007] Preferably, the thrust device is one of a hydraulic rod, a cylinder, or an electric telescopic rod.

[0008] Preferably, the bending rod includes a first support rod and a second support rod, wherein the ends of the first support rod and the second support rod are hinged together, and a first torsion spring is provided at the connection; the lower end of the first support rod is hinged together with the lower end of the support column, and a second torsion spring is provided at the connection; the thrust device is hinged together with the second support rod and is used to push the first support rod and the second support rod to rotate along the hinge.

[0009] Furthermore, both the first and second support rods have slots on their lower sides for limiting the position of the reserved reinforcing bars.

[0010] Preferably, a drive motor is fixedly connected to the upper side of the horizontal plate, a drive gear is fixedly connected to the main shaft of the drive motor, and a linkage gear is fixedly connected to the support column, with the linkage gear meshing with the drive gear.

[0011] Furthermore, the support column fixes the connecting plate, and two parallel sliding grooves are arranged on the plate. A slider is slidably connected in the sliding grooves. The slider has a sliding hole, the axis of which is parallel to the axis of the support column. A vertical rod is slidably connected in the sliding hole, and a roller is rotatably connected to the lower ends of the two vertical rods. A boss is provided in the middle of the vertical rod, and a support spring is fixedly connected between the boss and the slider. An arc-shaped block is provided on the upper side of the plate, and the arc-shaped block is located between the two vertical rods. A rolling column is rotatably connected to the upper ends of the two vertical rods, and the rolling column can contact the upper side of the arc-shaped block. A cylinder is rotatably connected to one side of the second support rod, and the cylinder can push the vertical rod to translate.

[0012] Preferably, a guide groove is provided on the upper side of the plate, and the guide groove is arranged parallel to the slide groove; a guide block is slidably connected in the guide groove, and the guide block is fixedly connected to the bottom of the arc-shaped block; along the direction of the upward movement of the rolling column, a flat pushing device is fixedly connected to one side of the plate, and the flat pushing device is fixedly connected to the guide block for pushing the guide block to move.

[0013] Preferably, the two ends of the horizontal plate are respectively fixedly connected to support seats, and the bottom of the support seat is provided with a snap-fit ​​groove for snap-fitting and fixing to the side wall of the steel caisson.

[0014] The advantages of this invention are as follows: The auxiliary construction equipment for rapid construction of deep-water submerged concrete foundations provided by this invention involves suspending a horizontal plate at the center of the pile column, driving a motor to rotate the support column to the corresponding construction position, and then bending the protruding pre-reserved steel bars one by one. Through the extension of the thrust device, the cylindrical side pusher vertical rod moves horizontally, and the rolling column rises on the arc-shaped block. Combined with the relative bending of the first and second support rods, this achieves the lifting and bending of the middle part of the pre-reserved steel bars, facilitating the bending of the pre-reserved steel bars and improving work efficiency.

[0015] This invention adjusts the position of the arc-shaped block acting on the rolling column, so that the position where the vertical rod is lifted is adjusted along the diameter direction of the pile column, which facilitates the bending of the reserved steel bars located at different positions of the pile column.

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0033] like Figure 1-6 As shown, the present invention provides an auxiliary construction device for rapid construction of deep-water submerged concrete foundations. In a specific embodiment, the auxiliary construction device includes a horizontal plate 1. The upper side of the horizontal plate 1 is provided with lifting lugs according to the specific crane model. Support seats 11 are fixedly connected to both ends of the horizontal plate 1. The bottom of the support seat 11 is provided with a snap-fit ​​groove 12 for easy snap-fit ​​fixing to the side wall of the steel lifting box 20. The upper end of the horizontal plate 1 is rotatably connected to the support column 2. The lower end of the support column 2 is hinged to the lower end of the bending rod 3. The outer side of the support column 2 is hinged to the fixed end of the thrust device 4. The telescopic end of the thrust device 4 is hinged to the upper end of the bending rod 3. A drive motor 411 is fixedly connected to the upper side of the horizontal plate 1. The main shaft of the drive motor 411 is fixedly connected to the drive gear 41. The support column 2 is fixedly connected to the linkage gear 42. The linkage gear 42 meshes with the drive gear 41 and is used to drive the support column 2 to rotate through the drive motor 411.

[0034] A horizontal plate 1 is hoisted at the center of the pile column 10, and its position relative to the pile column 10 is adjusted as needed during use. For example, when bending the reserved steel bars 30 on the outer edge of the pile column 10, the horizontal plate 1 can be placed at the center of the pile column 10, and then the reserved steel bars 30 can be bent one by one by rotation. When some reserved steel bars 30 near the inner side of the pile column 10 are difficult to bend, the position of the horizontal plate 1 can be adjusted. The drive motor 411 drives the support column 2 to rotate through the meshing drive gear 41 and linkage gear 42, and bends the protruding reserved steel bars 30 one by one, avoiding the problems of low efficiency of manual bending and safety hazards caused by the elastic rebound of the reserved steel bars 30.

[0035] The bending rod 3 includes a first support rod 31 and a second support rod 32. The first support rod 31 and the second support rod 32 are hinged at their adjacent ends, and a first torsion spring is provided at the connection point to facilitate the reset of the second support rod 32. The lower end of the first support rod 31 is hinged to the lower end of the support column 2, and a second torsion spring is provided at the connection point to facilitate the reset of the first support rod 31. The telescopic end of the thrust device 4 is hinged to the upper side of the second support rod 32 to push the first support rod 31 and the second support rod 32 to rotate along the hinge point. The lower sides of both the first support rod 31 and the second support rod 32 are provided with slots 311 to facilitate the entry of the reserved reinforcing bar 30 into the slots 311 and to limit its movement, preventing lateral slippage during the bending process of the reserved reinforcing bar 30.

[0036] A support column 2 is fixedly connected to a plate 5. Two parallel sliding grooves 51 are arranged on the plate 5, and sliders 52 are slidably connected within each groove 51. Each slider 52 has a sliding hole, the axis of which is parallel to the axis of the support column 2. Vertical rods 53 are slidably connected within the sliding holes, and a roller 54 is rotatably connected to the lower ends of the two vertical rods 53. A boss 55 is provided in the middle of each vertical rod 53, and a support spring 56 is fixedly connected between the boss 55 and the slider 52. An arc-shaped block 57 is provided on the upper side of the plate 5, located between the two vertical rods 53. A rolling column 58 is rotatably connected to the upper ends of the two vertical rods 53, and the rolling column 58 can contact the upper side of the arc-shaped block 57 and roll. A cylinder 321 is rotatably connected to one side of a second support rod 32. When the second support rod 32 approaches the vertical rod 53, the cylinder 321 can push the vertical rod 53 to translate. When the thrust device 4 extends, the cylindrical column 321 pushes the vertical rod 53 to translate, and the rolling column 58 rises along the upper surface of the arc-shaped block 57. During this process, in conjunction with the relative bending of the first support rod 31 and the second support rod 32, the middle part of the reserved steel bar 30 is lifted and bent, facilitating the bending operation of the reserved steel bar 30. After bending, the reserved steel bar 30 forms a curved distribution with the subsequent steel bar frame, and the mutual binding of the steel bars can improve the structural strength. This process does not require manual bending of the reserved steel bar, and the bending of the reserved steel bar by this auxiliary construction equipment greatly improves work efficiency.

[0037] A guide groove 6 is provided on the upper side of the plate 5, and the guide groove 6 is parallel to the slide groove 51. A guide block 61 is slidably connected in the guide groove 6, and the guide block 61 is fixedly connected to the bottom of the arc-shaped block 57. A flat pushing device 62 is fixedly connected to one side of the plate 5 along the upward movement direction of the rolling column 58. One end of the flat pushing device 62 extends into the guide groove 6 and is fixedly connected to the guide block 61 to push the guide block 61 to move. By pushing the guide block 61 to move through the flat pushing device 62, the position of the arc-shaped block 57 acting on the rolling column 58 is adjusted, so that the position of the vertical rod 53 is adjusted along the diameter direction of the pile column 10, which facilitates the bending of the reserved steel bars 30 located at different positions of the pile column 10.

[0038] Among them, the thrust device 4 and the flat thrust device 62 are one of hydraulic rod, cylinder or electric telescopic rod. This application pre-selects hydraulic rod, which provides stable thrust and fixes the hydraulic rod to the upper side of the horizontal plate 1.

[0039] During operation, a horizontal plate 1 is hoisted at the center of the pile column 10, and a drive motor 411 drives the support column 2 to rotate, bending each of the extended pre-reserved steel bars 30 one by one. By controlling the extension of the thrust device 4, the cylindrical column 321 pushes the vertical rod 53 to move horizontally, and the rolling column 58 rises along the upper surface of the arc-shaped block 57. During this process, in conjunction with the relative bending of the first support rod 31 and the second support rod 32, the middle part of the pre-reserved steel bars 30 is lifted and bent, which facilitates the bending operation of the pre-reserved steel bars 30 and improves work efficiency.

[0040] Furthermore, by adjusting the position of the arc-shaped block 57 on the connecting plate 5, the contact position of the arc-shaped block 57 relative to the rolling column 58 will also change, thereby adjusting the position of the vertical rod 53 along the diameter direction of the pile column 10, which facilitates the bending of the reserved steel bars 30 located at different positions of the pile column 10.

[0041] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
