As used herein, unless the context clearly indicates otherwise, the singular forms "one (kind, person)" and "the" are also intended to include plural forms. In addition, when the terms "comprise" and / or "include" and their variations are used in this manual, the features, integral bodies, steps, operations, parts, assemblies and / or their groups stated are indicated, but the presence or addition of one or more other features, integral bodies, steps, operations, parts, assemblies and / or their groups is not excluded.

[0021] A specific embodiment of the present invention, as Figures 1-6 As shown, a movable hanger for pile foundations adjacent to operating lines is disclosed, comprising: a base 10, with a mounting hole 11 formed on the base 10; A hoisting mechanism 20 is provided on the base 10 and is used to hoist the steel cage; The telescopic track mechanism 30 is provided on the base 10 and can extend outward from the base 10; The middle lifting mechanism 40 is movably arranged on the telescopic track mechanism 30; The bottom lifting mechanism 50 is movably arranged on the telescopic track mechanism 30; The middle lifting mechanism 40 is arranged between the mounting hole 11 and the bottom lifting mechanism 50. When the hoisting mechanism 20 lifts the first end of the lying steel cage upward, the middle dragging mechanism can move between the two ends of the steel cage, lift the second end of the steel cage off the ground, so that the bottom lifting mechanism 50 moves to the second end of the steel cage and drags the second end of the steel cage off the ground. The bottom lifting mechanism 50 and the middle lifting mechanism 40 cooperate with the hoisting mechanism 20 to place the steel cage upright and then place it into the mounting hole 11.

[0022] The hoisting mechanism 20 provides an upward lifting force by connecting to the first end (usually the top) of the steel cage, causing the steel cage to rotate around the bottom fulcrum. At the same time, the telescopic track mechanism 30 extends outward from the base 10, and the middle lifting mechanism 40 and the bottom lifting mechanism 50 move to the designated position. The middle lifting mechanism 40 first contacts the middle of the steel cage, lifts the second end (bottom) off the ground, and then the bottom lifting mechanism 50 moves to the bottom of the steel cage. Through the coordinated movement of the hoisting mechanism 20, the middle lifting mechanism 40 and the bottom lifting mechanism 50, the steel cage gradually changes from a lying state to a vertical state, and is finally accurately placed in the installation hole 11. Through the coordinated work of multiple mechanisms, the fully automatic conversion process of the steel cage from lying to vertical is realized, avoiding the tedious steps and safety risks of manually assisting in adjusting the posture in traditional hoisting methods.

[0023] A vertical downward pointing laser emitting device 99 is provided on the top crossbeam of the hanger 203. After the hanger 203 is in place, the position of the hanger 203 is fine-tuned by the pointing laser emitting device 99 to reduce the installation deviation of the steel cage.

[0024] In this embodiment, because the rebar cage is grid-shaped, when the middle lifting mechanism 40 moves to the bottom of the rebar cage, it does not slide in closely against the cage, but rather slides in with a gap. The middle lifting mechanism 40 then lifts the cage, raising the second end cup of the cage. The bottom lifting mechanism 50 moves to the bottom of the cage and lifts it. It should be noted that the middle lifting mechanism 40 can be lowered at this point, and only the bottom lifting mechanism 50 needs to lift the cage. At the same time, because the bottom lifting mechanism 50 is located at the rear end of the cage, the cage can slide off the bottom lifting mechanism 50, and the cage will not be restricted when it is separated from the bottom lifting mechanism 50.

[0025] In some embodiments, the hoisting mechanism 20 includes a hoisting motor 201, a hoisting rope 202, and a hanger 203. The hoisting motor 201 is connected to the base 10. The hanger 203 is mounted on the base 10 and positioned directly above the mounting hole 11. The hoisting rope 202 is wrapped around the output shaft of the hoisting motor 201. The other end of the hoisting rope 202 passes through the hanger 203 and extends toward the mounting hole 11. A connecting claw is connected to the other end of the hoisting rope 202. The hoisting motor 201 serves as the power source, driving the hoisting rope 202 to wind around or release it on its output shaft. The hoisting rope 202 is redirected by the hanger 203 at the top, extending vertically downward to above the mounting hole 11. The connecting claw serves as the interface between the hoisting rope 202 and the rebar cage, securely securing the first end of the rebar cage through mechanical locking or hydraulic clamping. When the hoisting motor 201 is activated, the hoisting rope 202 tightens, generating an upward pulling force that overcomes the weight of the rebar cage and lifts it upward.

[0026] The telescopic track mechanism 30 includes a sleeve 301, a slide rail 302, and an on-track motor 303. The sleeve 301 includes two sleeves, one on each side of the base 10. The slide rail 302 is sleeved within the sleeve 301 and slidably connected to the sleeve 301 and the on-track motor 303 is disposed on the base 10. The drive shaft of the on-track motor 303 is connected to a gear. The top surface of the slide rail 302 is provided with a tooth groove. The gear of the on-track motor 303 engages with the slide rail 302 through a connection opening on the top surface of the sleeve 301, allowing the on-track motor 303 to drive the slide rail 302 to move. The telescopic track mechanism 30 utilizes the rack and pinion transmission principle. The on-track motor 303 drives the gear to rotate, and the gear engages with the tooth groove on the top surface of the slide rail 302. When the on-track motor 303 rotates, the meshing action of the gear teeth converts the rotational motion into linear motion of the slide rail 302 within the sleeve 301. Sliding sleeve 301 acts as a guide rail, providing guidance and support for slide rail 302, ensuring smooth movement. This mechanism allows for flexible adjustment of the rail length based on actual lifting requirements, expanding the equipment's operational range. Especially when handling rebar cages of varying lengths, extending the rails allows the middle and bottom support mechanisms 40 and 50 to reach optimal support positions, enhancing the equipment's versatility and adaptability.

[0027] In some embodiments, the central lifting mechanism 40 includes a central driver 401, a crossbeam 402, a vertical frame 403, and a support plate 404. The central driver 401 includes two central drivers 401, each connected to two slide rails 302. The two central drivers 401 move synchronously. The crossbeam 402 connects the two central drivers 401, enabling the central driver 401 to move on the slide rails 302. The vertical frame 403 includes two vertical frames 403, each connected to the ends of the crossbeam 402. The support plate 404 is connected to the two vertical frames 403, and the vertical frames 403 are vertically connected to the crossbeam 402. The two central drivers 401 of the central lifting mechanism 40 are respectively installed on the slide rails 302 on both sides, and synchronized movement along the rails is achieved through synchronous control. The crossbeam 402 connects the two central drivers 401 to form a rigid frame structure. The vertical frames 403 are vertically installed at both ends of the crossbeam 402 to support the support plate 404 at the top. When the steel cage is partially lifted, the middle driver 401 drives the support plate 404 to move to the bottom of the middle of the steel cage. The support plate 404 rises to contact and support the steel cage, sharing the load of the lifting mechanism 20. At the same time, the support plate 404 lifts the steel cage to facilitate the bottom lifting mechanism 50 to enter the bottom of the steel cage.

[0028] The middle driver 401 has a built-in drive motor and a drive wheel, and moves on the slide rail 302 via the drive wheel.

[0029] In some embodiments, the support plate 404 is a V-shaped structure, with the groove of the support plate 404 facing upward, so that the side wall of the steel cage is connected to the two side walls of the groove of the support plate 404.

[0030] The groove design of the V-shaped support plate 404 enables it to form a linear contact with the outer surface of the cylindrical steel cage, and the two inclined side walls of the groove are tangent to the circumferential surface of the steel cage. When the support plate 404 supports the steel cage, the contact points are located at the two side edges of the groove, forming a stable two-point support structure. This structural design increases the contact area between the support plate 404 and the steel cage, reduces the pressure per unit area, and avoids damage to the steel cage caused by local stress concentration. At the same time, the self-centering effect of the V-shaped structure prevents the steel cage from rolling or sliding on the support plate 404, improving the stability of the support and ensuring the safety of the lifting process.

[0031] In some embodiments, the bottom lifting mechanism 50 includes a bottom driver 501, a rotating shaft 502, a clamping mechanism, and a driving structure. The bottom driver 501 includes two, and the two bottom drivers 501 are respectively connected to the two slide rails 302. The two bottom drivers 501 move synchronously. The rotating shaft 502 is respectively connected to the two bottom drivers 501. The clamping mechanism is set on the rotating shaft 502, and the driving structure drives the clamping mechanism to rotate on the rotating shaft 502.

[0032] In some embodiments, the clamping mechanism includes a first clamping plate 503, a second clamping plate 504, and a third clamping plate 505, all of which are connected to the driving structure through connecting parts. The first clamping plate 503 is located at the bottom and can be attached to the lower outer wall of the steel cage. The third clamping plate 505 is located at the top and can be attached to the upper inner wall of the steel cage. The second clamping plate 504 is located in the middle and can be attached to the lower inner wall of the steel cage.

[0033] The first clamping plate 503 has a V-shaped structure, with the groove facing upward, allowing the sidewalls of the rebar cage to contact the two sidewalls of the first clamping plate 503. The V-shaped groove of the first clamping plate 503 matches the outer circumference of the rebar cage. The angle of the groove is typically designed to be 60°-120° to ensure sufficient contact with the rebar cage surface. When the clamping plate clamps the rebar cage, the two sidewalls of the groove form a line contact with the outer surface of the rebar cage, and the contact line is distributed along the circumference of the rebar cage.

[0034] The second and third plates 504, 505 are both flat plates, allowing their ends to abut against opposite sides of the inner wall of the rebar cage. Both plates 504 and 505 are flat plates with a width smaller than the inner diameter of the rebar cage. The ends of the plates abut against opposite sides of the inner wall of the rebar cage, creating a horizontal constraint.

[0035] In some embodiments, the driving structure includes a first internal drive motor, a second internal drive motor, and a third internal drive motor, all of which are arranged inside the rotating shaft 502. The outer wall of the middle part of the rotating shaft 502 is provided with a first rotating ring 506, a second rotating ring 507, and a third rotating ring 508 in sequence. The first rotating ring 506, the second rotating ring 507, and the third rotating ring 508 are all rotatably connected to the rotating shaft 502. Windows are provided on the side walls corresponding to the rotating shaft 502 and the first rotating ring 506, the second rotating ring 507, and the third rotating ring 508. The gear on the first internal drive motor is meshed with the first rotating ring 506 through the window, the gear on the second internal drive motor is meshed with the second rotating ring 507 through the window, and the gear on the third internal drive motor is meshed with the third rotating ring 508 through the window.

[0036] The third plate 505 moves to the top of the second plate 504, and then moves toward the steel cage. The first plate 503 moves to the outer wall of the bottom of the steel cage, and the second plate 504 and the third plate 505 are together. The plate 505 enters the second end of the steel cage, causing the first clamping plate 503, the second clamping plate 504, and the third clamping plate 505 to rotate and abut against the side wall of the steel cage to fix the steel cage. Subsequently, the vertical frame 403 retracts, so that the first end and the second end of the steel cage are lifted. At the same time, the middle driver 401 and the bottom driver 501 move toward the mounting hole 11, and the lifting motor 201 lifts the steel cage to move. At this time, the first clamping plate 503, the second clamping plate 504, and the third clamping plate 505 all move with the steel cage. The steel cage rotates and maintains the clamping. When the steel cage is close to the installation hole 11, the steel cage needs to pass through the middle lifting mechanism 40 and become a vertical state. At this time, the first clamping plate 503 is controlled to continue to move and rotate to the top of the middle lifting mechanism 40 to form a feeding channel. The steel cage is supported by the first clamping plate 503 and passes through the middle lifting mechanism 40. It is then lifted by the lifting motor 201 and becomes a vertical state. In this process, after the steel cage passes through the middle lifting mechanism 40, it is in a suspended state as a whole and will not touch the bottom. The hanger 203 can be set to a lifting structure controlled by a motor to ensure that the steel cage is suspended. A motor heat dissipation channel (connected to an external cooling fan) is set inside the rotating shaft 502, sealing rings are set on the inner sides of the first rotating ring 506, the second rotating ring 507, and the third rotating ring 508 (the contact part with the rotating shaft 502), and an overload protection pin is set on the connecting piece between the rotating ring and the splint.

[0037] The base 10 of the present application is moved by a mobile device so that the mounting hole 11 on the base 10 is aligned with the ground hole where the steel cage is to be installed. The steel cage is moved off the flatbed truck by placing the hanger 100 and placed in the loading position.

[0038] The above specific implementation methods further illustrate the purpose, technical solutions and beneficial effects of this application in detail. It should be understood that the above are only specific implementation methods of this application and are not intended to limit the scope of protection of this application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of this application should be included in the scope of protection of this application.
