[0002] With the maturity of my country's construction engineering technology and the rapid development of the industry, cement mixing piles and bored cast-in-place piles are widely used in foundation reinforcement and other projects, especially the one-slot and two-cage underground continuous wall construction technology. Since cement mixing piles have the characteristics of large pile diameter and long pile body, the pile foundation steel cage is too long to be installed in whole sections. It is generally manufactured in sections. After the drilling is completed, the steel cage is lifted section by section at the pile hole position, and the steel cage is vertically connected to complete the installation. During the steel cage connection work, the connection of the main reinforcement of the steel cage is often achieved through a threaded sleeve.

[0003] In the prior art, when performing the steel cage docking work, usually one section of the steel cage is first sunk into the pile hole, and then the other section of the steel cage is hoisted by a hoisting device so that the main bars of the two sections of the steel cage correspond to each other. Then the operator uses tools such as wrenches to connect the threaded sleeves to the main bars corresponding to the two sections of the steel cage to complete the assembly. However, this construction method is time-consuming and labor-intensive, and the process of manually tightening the threaded sleeves takes a relatively large amount of time, which greatly reduces the progress of the steel cage docking construction.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings. The same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper", "lower", "bottom" and "top" used in the following description refer to directions in the accompanying drawings, and the terms "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0029] The present invention discloses a steel cage docking device for engineering construction, such as Figure 1 and Figure 2 As shown, it includes a first steel cage arranged in the pile hole and a second steel cage arranged on the top of the first steel cage, and also includes a cylinder 1 and a limiting cylinder 15. The cylinder 1 is arranged outside the top of the first steel cage. A fixing plate 11 is coaxially fixed on the outer side wall of the bottom end of the cylinder 1. Four anchor rods 12 can be vertically penetrated on the fixing plate 11. The tip of the anchor rod 12 penetrates the fixing plate 11 and is inserted into the ground. The outer side wall of the threaded part of the anchor rod 12 is threadedly connected with a nut 121 pressed on the top surface of the fixing plate 11. The nut 121 can press the fixing plate 11 on the ground. The top surface of the fixed plate 11 is fixedly connected to a circular plate 14 coaxial with the cylinder body 1 and located at the top of the cylinder body 1 through four vertically arranged connecting columns 13. The limiting cylinder 15 is coaxially fixed to the inner wall of the circular plate 14. A group of limiting components 16 uniformly spaced along the circumferential direction of the inner wall of the limiting cylinder 15 are arranged in the limiting cylinder 15. The limiting components 16 can limit the second steel cage that is lowered and docked.

[0030] When performing the steel cage docking work, the first steel cage is placed in the pile hole, and then the cylinder 1 is sleeved on the outside of the first steel cage and placed on the ground. The anchor rod 12 is vertically passed through the fixing plate 11 and inserted into the ground and the fixing plate 11 is compressed by the nut 121 to achieve the fixation of the cylinder 1 on the ground. Then the second steel cage is lifted by the lifting equipment and vertically lowered from the top of the limiting cylinder 15. During the lowering process of the second steel cage, the second steel cage is limited by a group of limiting components 16 arranged in the limiting cylinder 15, so that the main reinforcement of the second steel cage and the first steel cage can be aligned, which is convenient for docking.

[0031] like Figure 2 and Figure 3 As shown, the limiting assembly 16 includes a third electric push rod 161 and a round roller 163. The third electric push rod 161 is horizontally installed on the side wall of the limiting cylinder 15 along the radial direction of the limiting cylinder 15. The output end of the third electric push rod 161 extends into the limiting cylinder 15. The round roller 163 is horizontally rotatably connected to the output end of the third electric push rod 161 through a concave connecting plate 162. The third electric push rod 161 can make the round roller 163 contact with the outer wall of the second steel cage.

[0032] When the second steel cage is lowered through the limiting tube 15 to dock with the first steel cage, the third electric push rod 161 is started to drive the connecting plate 162 and the round roller 163 to move, so that the round roller 163 contacts the outer wall of the second steel cage. The second steel cage is limited by the cooperation of the four round rollers 163 arranged around the second steel cage, thereby reducing the possibility of shaking and deflection of the second steel cage during the lowering process, so that the main reinforcement of the second steel cage can be aligned with the main reinforcement of the first steel cage.

[0033] like Figure 1 and Figure 4 As shown, threaded sleeves are installed on the outer side walls at the top ends of the main bars of the first steel cage, and the threaded sleeves can realize the connection between the main bars of the first steel cage and the second steel cage. A gear column 4 is coaxially fixed on the outer wall of each threaded sleeve, and a support ring 2 is coaxially rotatably connected to the top surface of the cylinder 1. The bottom surface of the support ring 2 is coaxially fixed with a gear ring 21 surrounding the outside of the cylinder 1. A driving component 5 that can drive the gear ring 21 to rotate is arranged on the outer side wall of the cylinder 1. The driving component 5 includes a second motor 51 and a second spur gear 52. The second motor 51 is vertically installed on the outer side wall of the cylinder 1. The second motor 51 is a brake motor. The output end of the second motor 51 is coaxially fixed with a second rotating shaft 511, and the second spur gear 52 is coaxially fixed on the outer side wall at the top end of the second rotating shaft 511. The second spur gear 52 is meshed with the gear ring 21. Two tightening mechanisms 3 that can respectively cooperate with the gear columns 4 on the two main bars of the first steel cage are arranged on the top surface of the support ring 2. The tightening mechanism 3 can automatically rotate the threaded sleeve to connect the main bars of the first steel cage and the second steel cage.

[0034] After the second steel cage is lowered and aligned with the main bars of the first steel cage, the second motor 51 is started to drive the second rotating shaft 511 and the second spur gear 52 to rotate. Under the meshing cooperation of the second spur gear 52 and the gear ring 21, the support ring 2 drives the two tightening mechanisms 3 to adjust their positions, so that the two tightening mechanisms 3 can respectively cooperate with the gear columns 4 on the two main bars of the first steel cage. The tightening mechanisms 3 realize the automatic rotation of the threaded sleeve by driving the gear columns 4 to rotate, thereby realizing the docking of the main bars of the first steel cage and the second steel cage. After the two tightening mechanisms 3 complete the automatic rotation of the threaded sleeves on the two main bars, the second motor 51 drives the support ring 2 to rotate a certain angle, so that the two tightening mechanisms 3 can be aligned with the two main bars on the vacant workstations, so that the tightening mechanisms 3 can automatically rotate the threaded sleeves on the main bars in turn.

[0035] like Figure 1 , Figure 4 and Figure 5 As shown, the tightening mechanism 3 includes a support plate 31, a first electric push rod 32, a first motor 33, a first spur gear 34 and a pushing member 35. The support plate 31 is installed on the top surface of the support ring 2, the first electric push rod 32 is vertically installed on the top surface of the support plate 31, the first motor 33 is vertically installed on the top of the output end of the first electric push rod 32, the output end of the first motor 33 is coaxially fixed with a first rotating shaft 331, the first spur gear 34 is coaxially fixed to the outer wall of the top end of the first rotating shaft 331, and the pushing member 35 is arranged on the outside of a side of the first electric push rod 32 away from the first steel cage. The pushing member 35 can push the first electric push rod 32 to move to cause the first spur gear 34 to engage with the gear column 4.

[0036] When the support plate 31 is adjusted to the specified position for automatic rotation of the threaded sleeve, the pushing member 35 pushes the first electric push rod 32 to move in the direction close to the first steel cage, causing the first spur gear 34 to engage with the gear column 4, and then the first motor 33 is started to drive the first spur gear 34 to rotate and the first electric push rod 32 is started to drive the first spur gear 34 to gradually move up. Under the engagement cooperation between the first spur gear 34 and the gear column 4, the threaded sleeve rotates and moves up and gradually sleeves on the main reinforcement of the second steel cage, thereby realizing the automatic rotation of the threaded sleeve to connect the main reinforcement of the first steel cage and the second steel cage. After completing the automatic rotation of the threaded sleeve on one main reinforcement, the pushing member 35 drives the first electric push rod 32 away from the first steel cage, and the first electric push rod 32 drives the first motor 33 to move down and reset, so that the threaded sleeve on the vacant workstation can be rotated again later.

[0037] like Figure 1 , Figure 4 and Figure 5 As shown, a first slide groove 311 is horizontally opened on the top surface of the support plate 31 and is arranged radially along the support ring 2. The longitudinal section of the first slide groove 311 is in a dovetail shape. The pushing member 35 includes a second electric push rod 351 and a first slider 352. The first slider 352 is slidably connected to the inner wall of the first slide groove 311. The bottom end of the first slider 352 is in a dovetail shape that cooperates with the inner wall of the first slide groove 311. The top end of the first slider 352 extends to the top of the support plate 31. The first electric push rod 32 is vertically installed on the top surface of the first slider 352. The second electric push rod 351 is horizontally installed on the top surface of the support plate 31 along the radial direction of the support ring 2. The output end of the second electric push rod 351 is fixedly connected to the outer wall of the first slider 352 away from the first steel cage.

[0038] The first electric push rod 32 can be moved by starting the second electric push rod 351 to drive the first slider 352 to slide along the inner wall of the first slide groove 311, so that when the threaded sleeve needs to be rotated, the first electric push rod 32 can make the first spur gear 34 engage with the gear column 4. After the threaded sleeve is automatically rotated, the first electric push rod 32 can separate the first spur gear 34 from the gear column 4, so as to automatically rotate the threaded sleeves on each vacant workstation subsequently.

[0039] like Figure 4 , Figure 6 and Figure 7As shown, an arc-shaped groove 22 is provided on the top surface of the support ring 2, and the longitudinal cross-section of the arc-shaped groove 22 is L-shaped. A through hole 23 is provided on the inner side wall of the arc-shaped groove 22. The bottom surfaces of the two support plates 31 are fixedly connected with limit blocks 36 that slide with the inner wall of the arc-shaped groove 22. The side walls of the two limit blocks 36 close to the through hole 23 are provided with fasteners 37 that can fix the limit blocks 36. The fasteners 37 include fastening bolts 371 and washers 372. Threaded holes 361 are horizontally provided on the side walls of the two limit blocks 36 close to the through hole 23. The screw portion of the fastening bolt 371 can horizontally pass through the through hole 23 and be threadedly connected to the inner side wall of the threaded hole 361. The washer 372 is sleeved on the screw portion of the fastening bolt 371 and is blocked outside the support ring 2. The head of the fastening bolt 371 can press the washer 372 against the outer side wall of the support ring 2.

[0040] By moving the positions of the two support plates 31, the angle between the two tightening mechanisms 3 can be adjusted so that the angle between the two tightening mechanisms 3 can match the angle between the two adjacent main bars of the first steel cage. After the positions of the two support plates 31 are adjusted, the limit blocks 36 can be fixed by tightening the bolts 371 to fix the positions of the support plates 31, so that the two tightening mechanisms 3 can synchronously tighten the two main bars of the first steel cage respectively, thereby improving the overall work efficiency.

[0041] Working principle: When the steel cage is docked, the first steel cage is placed in the pile hole, and then the cylinder 1 is sleeved on the outside of the first steel cage and placed on the ground. Then the anchor rod 12 is vertically passed through the fixing plate 11 and inserted into the ground, and the fixing plate 11 is pressed by the nut 121 to fix the cylinder 1 on the ground. Then the second steel cage is lifted by the lifting equipment and lowered vertically from the top of the limiting cylinder 15. When the lifting equipment lowers the second steel cage through the limiting cylinder 15 to dock with the first steel cage, the third electric push rod 161 is started to drive the connecting plate 162 and the round roller 163 to move, so that the round roller 163 contacts the outer wall of the second steel cage. The second steel cage is limited by the cooperation of the four round rollers 163 arranged around the second steel cage, so as to reduce the possibility of shaking and deflection of the second steel cage during the lowering process, so that the main reinforcement of the second steel cage can be aligned with the main reinforcement of the first steel cage. When the main bars of the two steel cages are aligned, the second electric push rod 351 is started to drive the first electric push rod 32 to move toward the direction close to the first steel cage, so that the first spur gear 34 is meshed with the gear column 4 outside the threaded sleeve, and then the first motor 33 is started to drive the first spur gear 34 to rotate and the first electric push rod 32 is started to drive the first spur gear 34 to gradually move up. Under the meshing cooperation of the first spur gear 34 and the gear column 4, the threaded sleeve rotates and moves up and gradually sleeves on the main bars of the second steel cage, so that the threaded sleeve automatically rotates to connect the main bars of the first steel cage and the second steel cage; After the two tightening mechanisms 3 complete the automatic docking of the threaded sleeves on the two main bars of the first steel cage, the second motor 51 is started to drive the second spur gear 52 to rotate. Under the meshing cooperation of the second spur gear 52 and the gear ring 21, the support ring 2 drives the two tightening mechanisms 3 to rotate, so that the two tightening mechanisms 3 can be aligned with the two threaded sleeves on the next vacant workstation, so that the tightening mechanisms 3 can rotate the threaded sleeves on the vacant workstations of the first steel cage in turn, thereby realizing the automatic docking of the first steel cage and the second steel cage, reducing the trouble of manually tightening the threaded sleeves, saving manpower, and improving the work efficiency of the steel cage docking work.

[0042] 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.
