[0002] In modern construction projects, pile foundations, as an important basic engineering structure, are widely used in the construction of high-rise buildings, bridges, docks and other projects. The main function of the pile foundation is to transfer the load of the superstructure to the deeper soil or rock layer through the pile body, thereby improving the stability and bearing capacity of the building. The pile foundation is usually composed of the pile body and the pile top. Among them, the steel cage is an important component of the pile foundation. It is responsible for bearing the internal forces of the pile body and ensuring the overall strength and stability of the pile body. The production of the steel cage usually requires assembly and lowering at the construction site.

It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant invention and are not intended to limit the invention. It should also be noted that, for ease of description, only portions relevant to the invention are shown in the accompanying drawings.

[0056] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0057] Example 1

[0058] Please refer to Figures 1-8 The present embodiment provides a detachable pile foundation reinforcement cage automatic cage lowering device, comprising a support base 100, wherein the support base 100 comprises a plurality of support units 101, wherein the plurality of support units 101 are detachably connected along the extension direction of the support base 100, and the support base 100 is provided with:

[0059] An upper cage assembly 200 is installed at one end of the support base 100 and is used to lift the steel cage and deliver the steel cage to the other end of the support base 100 for hoisting;

[0060] The cage assembly 300 is used to align the cage with the pile hole when the cage is lowered and to fix the steel cage in the pile hole;

[0061] A positioning assembly 400 is provided on a side of the fixed cage assembly 300 away from the upper cage assembly 200. The positioning assembly 400 includes a first state and a second state. When in the first state, the positioning assembly 400 assists the steel cage in being conveyed along the extension direction of the support base 100. When in the second state, the positioning assembly 400 vertically lifts the steel cage along a direction perpendicular to the extension direction of the support base 100.

[0062] The lower cage assembly 500 is provided at one end of the positioning assembly 400 away from the fixed cage assembly 300. The lower cage assembly 500 is used to hoist the steel cage and to lower the cage when the positioning assembly 400 is in the second state.

[0063] Specifically, such as Figure 1 and Figure 2 As shown, the support base 100 is composed of two long straight rods 110, which are parallel to each other and are designed to be placed on the ground. Each long straight rod 110 is composed of multiple support units 101, which are short straight sleeves. By connecting and fixing multiple straight sleeves together, the length of the long straight rod 110 is increased, thereby increasing the extension length of the support base 100 to accommodate rebar cages of different lengths. For longer rebar cages, increasing the length of the support base 100 can improve the stability of the device when the cage is lowered.

[0064] The upper cage assembly 200 is arranged at one end of the support base 100. The upper cage assembly 200 can be automatically raised and lowered. It is lowered to a lower position to facilitate the placement of the steel cage on the upper cage assembly 200. After the steel cage is placed on the upper cage assembly 200, the upper cage assembly 200 is raised to lift the steel cage onto the automatic lower cage device; and the upper cage assembly 200 can also drive the steel cage so that the steel cage can be transported to the other end of the support base 100 for lifting. The entire lifting and transportation process does not require human participation.

[0065] The solid cage assembly 300 is installed on the side of the upper cage assembly 200 close to the side where the steel cage is hoisted. The solid cage assembly 300 is arranged between the two long straight rods 110. When construction is carried out at the construction site, the two long straight rods 110 are erected on the ground on both sides of the pile hole. The solid cage assembly 300 is aligned with the pile hole position. Each time a section of the steel cage is lowered into the pile hole, the steel cage in the pile hole can be fixed by the solid cage assembly 300. Then, after the next section of the steel cage is hoisted and lowered into the pile hole, the front and rear sections of the steel cage can be conveniently welded. The shaking of the steel cage can be avoided during the welding process, thereby improving the stability during welding.

[0066] The positioning assembly 400 is installed on the side of the fixed cage assembly 300 away from the upper cage assembly 200. The positioning assembly 400 is arranged between the two long straight rods 110 and above the two long straight rods 110. The positioning assembly 400 can rotate relative to the support base 100 at one end close to the fixed cage assembly 300. The positioning assembly 400 has a first state and a second state during the relative rotation with the support base 100. In the first state, the positioning assembly 400 and the long straight rods 110 extend in the same direction, and the height of the positioning assembly 400 is close to the height of the upper cage assembly 200 after it is raised, so as to facilitate the support of the steel cage transported from the upper cage assembly 200 to the hoisting position and guide the transport of the steel cage. In the second state, the positioning assembly 400 can fix the steel cage and place it in a position perpendicular to the extension direction of the long straight rods 110 to vertically place the steel cage. After the steel cage is vertically placed, it is aligned with the fixed cage assembly 300, which facilitates the subsequent hoisting and lowering of the steel cage into the pile hole.

[0067] The lower cage assembly 500 is installed at one end of the positioning assembly 400 away from the fixed cage assembly 300. The lower cage assembly 500 can lift the steel cage when the positioning assembly 400 is placed in the second state. After the positioning assembly 400 releases the fixation of the steel cage, the steel cage can be lowered into the pile hole through the lower cage assembly 500.

[0068] The automatic cage lowering device provided in the present application rarely requires human intervention during the entire working process. The construction personnel only need to weld at the connection position of the two sections of the steel cage, and the rest of the process is completed by the device itself, which improves the working efficiency, reduces the errors caused by human participation, and reduces the safety risks of the construction personnel; and, the cage lowering device can effectively ensure the accuracy of the position of the steel cage when lowering the cage in the pile hole, thereby improving the cage lowering accuracy.

[0069] Furthermore, the upper cage assembly 200 includes:

[0070] A support platform 210 is provided on the surface of the support platform 210 for supporting the steel cage. A conveyor belt 220 for conveying the steel cage is provided on the surface of the support platform 210. A first protrusion 221 is provided on the surface of the conveyor belt 220. Arc-shaped levers 230 are provided on both sides of the support platform 210.

[0071] A plurality of rotating rods 240, each of which is provided on both sides of the support platform 210, one end of each rotating rod 240 being hinged to the side wall of the support platform 210, and the other end being hinged to the support base 100;

[0072] The first driving device 250 is used to drive the rotating rod 240 and the supporting base 100 to rotate relative to each other.

[0073] Specifically, such as Figure 2 As shown, the upper cage assembly 200 mainly includes a support platform 210, which is a flat plate parallel to the two long straight rods 110. Two rotating rods 240 are provided on each side of the support platform 210, one end of the rotating rod 240 is hinged to the support platform 210, and the other end is hinged to the long straight rod 110 on the corresponding side. The rotating rod 240 is driven by a first drive device 250 to rotate relative to the long straight rod 110, and the rotation of the rotating rod 240 can drive the support platform 210 to rise and fall. Optionally, the first drive device 250 is a drive motor; by lowering the support platform 210, it is convenient to place the steel cage, and then the support platform 210 is raised to place the cage; in order to improve the stability of the steel cage when the support platform 210 is placed on the cage, two arc-shaped stop rods 230 are provided on both sides of the support platform 210, which play a role in limiting the steel cage and preventing the steel cage from falling off the support platform 210.

[0074] A conveyor belt 220 is provided on the surface of the support platform 210. When the steel cage is placed on the support platform 210, the steel cage can be driven by the conveying action of the conveyor belt 220 to realize the conveyance of the steel cage. In order to improve the conveying efficiency of the steel cage, a plurality of first protrusions 221 are provided on the surface of the conveyor belt 220. The first protrusions 221 are metal protrusions, which can contact the steel cage during the conveying process of the conveyor belt 220, thereby increasing the friction between the steel cage and the conveyor belt 220, and preventing the steel cage and the conveyor belt 220 from sliding against each other and affecting the conveying efficiency.

[0075] Furthermore, the cage assembly 300 includes:

[0076] A pair of first clamps 310, wherein the first clamps 310 are movably mounted on the support base 100, the first clamps 310 are arc-shaped and the pair of first clamps 310 are disposed opposite to each other to form a ring clamp, and the pair of first clamps 310 can move closer to or farther away from each other;

[0077] A plurality of second protrusions 320 are disposed on the inner side of the first clamp 310 .

[0078] Specifically, such as Figure 3As shown, the first clamp 310 is arc-shaped, and a pair of first clamps 310 are movably mounted on two long straight rods 110 respectively. The first clamps 310 can move in a horizontal direction perpendicular to the extension of the long straight rod 110, so that the pair of first clamps 310 can be close to or away from each other. When the steel cage needs to be lowered into the pile hole, the pair of first clamps 310 are controlled to move away from each other to avoid affecting the lowering of the steel cage. After the steel cage is lowered into the pile hole and before the lower cage assembly 500 releases the steel cage, the pair of first clamps 310 are controlled to move close to each other to clamp the steel cage, thereby fixing the steel cage and ensuring the stability of the steel cage in the pile hole when the two sections of the steel cage are welded; optionally, the pair of first clamps 310 are driven by two cylinders respectively.

[0079] In order to improve the stability of the pair of first clamps 310 in clamping the steel cage, multiple second protrusions 320 are respectively provided on the side of the pair of first clamps 310 close to each other. The second protrusions 320 are metal protrusions used to increase the restrictive effect of the first clamps 310 on the steel cage.

[0080] Furthermore, the positioning component 400 includes:

[0081] A positioning support rod 410, one end of the positioning support rod 410 close to the cage assembly 300 is connected to the support base 100 via a second drive device 420, and a support foot 460 is provided at the other end of the positioning support rod 410.

The positioning mechanism 430 is used to assist the transmission of the steel cage when the positioning assembly 400 is in the first state, and to clamp and fix the steel cage when the positioning assembly 400 is in the second state.

[0083] Specifically, such as Figure 2 As shown, the positioning assembly 400 is composed of a positioning strut 410 and a positioning mechanism 430, wherein the positioning strut 410 is used to switch between the first state and the second state, and the positioning mechanism 430 is used to guide and fix the steel cage.

[0084] The positioning support rod 410 is a straight rod. When the positioning assembly 400 is in the first state, the positioning support rod 410 extends in a direction parallel to the two long straight rods 110. The positioning support rod 410 is located above the middle position of the two long straight rods 110. The positioning support rod 410 is provided with a second drive device 420 at one end close to the cage assembly 300. The second drive device 420 can be two drive motors. The two drive motors are connected to the positioning support rod 410 in a transmission manner. The two drive motors are installed on the two long straight rods 110 through the supporting plate 421. A supporting plate 421 is fixedly connected to the two long straight rods 110, and a support plate 422 is arranged between the two driving motors. The support plate 422 is fixed on the supporting plate 421, and the end of the positioning strut 410 is hinged to the support plate 422. The other end of the positioning strut 410 is provided with a support leg 460 for support; the positioning strut 410 is driven by the second driving device 420 so that the positioning strut 410 can be rotated.

[0085] The positioning mechanism 430 is installed on the positioning support rod 410. The positioning mechanism 430 also has two states. When the positioning assembly 400 is placed in the first state, the positioning mechanism 430 is placed in the first state. In the first state, the positioning mechanism 430 can guide the transmission of the steel cage; when the positioning assembly 400 is placed in the second state, the positioning mechanism 430 is placed in the second state. In the second state, the positioning mechanism 430 can fix the steel cage.

[0086] Furthermore, the positioning mechanism 430 includes:

[0095] A plurality of pairs of transmission gears 455 are provided. Each pair of transmission gears 455 is rotatably mounted on a corresponding fixing seat 441 and meshes with each other. Each pair of transmission gears 455 is fixed to a corresponding pair of second clamps 442 .

[0096] Specifically, such as Figure 5As shown, a fixed rod 451 passes through all of the fixed seats 441 and is connected to each fixed seat 441. A third drive device 453 is fixed to one end of the fixed rod 451 near the cage assembly 300. A gear rod 452 is rotatably mounted inside the fixed rod 451. The gear rod 452 extends in a direction parallel to the positioning support rod 410. The sidewalls of the gear rod 452 are provided with multiple sets of teeth that pass through the sidewalls of the fixed rod 451. The gear rod 452 is also in transmission connection with the third drive device 453, which can be a motor. Each set of teeth on the sidewalls of the gear rod 452 corresponds to the position of a fixed seat 441. The positions of multiple transmission racks 454 correspond one-to-one with the positions of the multiple fixed seats 441. The transmission racks 454 are semicircular in shape. Each transmission rack 454 meshes with a set of teeth at the position of the corresponding fixed seat 441, and one end of the transmission rack 454 is fixedly connected to one of the second clamps 442 mounted on the corresponding fixed seat 441.

[0097] When the third driving device 453 drives the gear rod 452 to rotate, the gear rod 452 rotates synchronously and drives all the transmission racks 454 to rotate. When each transmission rack 454 rotates, it drives a second clamp 442 fixedly connected to the transmission rack 454 on the corresponding fixed seat 441 to rotate. Since the pair of second clamps 442 on each fixed seat 441 are transmitted through a pair of transmission gears 455, when the second clamp 442 connected to the transmission rack 454 rotates, it drives the other second clamp 442 in the same pair to follow, thereby realizing the opening or clamping between the same pair of second clamps 442.

[0098] Furthermore, the second clamp 442 is provided with a plurality of rollers 443, and the rollers 443 are used to assist in conveying the steel cage when the second clamp 442 is opened; the second clamp 442 is also provided with a plurality of third protrusions 444, and the third protrusions 444 are used to assist in fixing the steel cage when the second clamp 442 is clamped.

[0099] Specifically, such as Figure 2 and Figure 5 As shown, multiple rollers 443 are located inside the second clamp 442 near the bottom. When the positioning assembly 400 is in the first state, the rebar cage is placed on the rollers 443 during transportation on the second clamp 442. The rollers 443 rotate as the rebar cage is transported, thereby reducing friction between the rebar cage and the second clamp 442 and improving transportation efficiency. Multiple third protrusions 444 are located inside the second clamp 442 at locations where the rollers 443 are not located. When the positioning assembly 400 is in the second state, the multiple third protrusions 444 can improve the stability of the fixation between the second clamp 442 and the rebar cage, preventing the rebar cage from falling off the second clamp 442. Optionally, the third protrusions 444 are metal protrusions.

The grab hooks 524 are fixed to the corresponding adjustment racks 523. The grab hooks 524 are used to hoist the steel cage. The fourth drive device 522 is used to adjust the distance between the pair of grab hooks 524.

[0103] The hoisting mechanism 530 is installed on the fixing plate 510 and connected to the mounting seat 521 . The hoisting mechanism 530 is used to drive the mounting seat 521 to rise and fall.

[0104] Specifically, such as Figure 6 As shown, the lower cage assembly 500 consists of a fixed plate 510, a clamping mechanism 520 and a hoisting mechanism 530, wherein the fixed plate 510 is fixed to the end of the positioning support rod 410 away from the fixed cage assembly 300 through a connecting rod 540, and the clamping mechanism 520 is connected to the fixed plate 510 through the hoisting mechanism 530. The clamping mechanism 520 is used to clamp the steel cage, and the hoisting mechanism 530 is used to drive the clamping mechanism 520 to rise and fall to achieve hoisting.

[0105] like Figure 6 and Figure 7 As shown, in the clamping mechanism 520, the mounting seat 521 is connected to the lifting mechanism 530, and a pair of adjusting racks 523 are colinearly arranged on the mounting seat 521. The adjusting rack 523 is slidably connected to the mounting seat 521, and the adjusting rack 523 is also transmission-connected to the fourth driving device 522. Optionally, the fourth driving device 522 is two driving motors, and the output shafts of the two driving motors are respectively engaged with the pair of adjusting racks 523 through gears. The two driving motors can drive the pair of adjusting racks 523 to approach or move away from each other, and a pair of grab hooks 524 are respectively fixedly mounted on the pair of adjusting racks 523, and the grab hooks 524 move with the adjusting racks 523; the grab hooks 524 are arc-shaped hooks, and the pair of grab hooks 524 are cross-arranged.

[0106] When the positioning assembly 400 is placed in the first state, the steel cage is transported to the position of the clamping mechanism 520 and is mounted on the outside of the clamping mechanism 520. The fourth driving device 522 drives a pair of adjustment racks 523 to move in opposite directions, thereby extending a pair of grab hooks 524 and hooking the steel cage from the inside of the steel cage, thereby fixing the steel cage and facilitating subsequent lifting by the lifting mechanism 530.

[0107] Furthermore, the hoisting mechanism 530 includes:

[0108] A disk 531 , on which a plurality of steel wire rope reels 532 are mounted, one end of each steel wire rope reel 532 being fixed to the mounting seat 521 ;

[0109] An annular rack 533 , the annular rack 533 is provided on the fixing plate 510 ;

[0111] The fifth driving device 536 is used to drive the transmission rod 535 to rotate, so that the disk 531 rotates relative to the fixed plate 510.

[0112] Specifically, such as Figure 8 As shown, the hoisting mechanism 530 consists of a disc 531, a wire rope reel 532, a circular rack 533, a plurality of support rods 534 and a fifth drive device 536. A circular through hole is provided at the center of the fixed plate 510, the mounting seat 521 is provided on the side of the through hole close to the cage assembly 300, the disc 531 is provided on the side of the through hole away from the cage assembly 300, the side wall of the through hole is provided with a groove, the circular rack 533 is provided in the groove of the side wall of the through hole, and is respectively provided on the two side walls of the groove; a plurality of support rods 534 are evenly arranged around the axis of the through hole, one end of the support rod 534 is fixed to the disc 531, and the other end is provided with a transmission rod 534 perpendicular to the support rod 534. 5.

[0113] When the positioning assembly 400 is placed in the first state, the mounting seat 521 is tightened by tightening the wire rope reel 532, so that the mounting seat 521 is close to the fixing plate 510 to prevent the fixing plate 510 from shaking; when the steel cage reaches the clamping mechanism 520, the fourth drive device 522 drives a pair of hooks 524 to open to fix the steel cage; when the positioning assembly 400 is placed in the second state, the wire rope reel 532 is released, so that the wire rope reel 532 can drive the steel cage to be lowered, during which time the transmission rod 535 is driven to rotate by the fifth drive device 536, and then the disc 531 can rotate, and the wire rope reel 532 drives the steel cage to rotate, so that it is more convenient to align with the steel cage in the pile hole and facilitate welding.

[0114] Example 2

[0115] This embodiment provides an automatic cage lowering control method, based on the automatic cage lowering device for a detachable pile foundation reinforcement cage as described in Example 1, the method comprising:

[0116] S1: Control the positioning assembly 400 to be in the first state and control the upper cage assembly 200 to descend.

[0117] Specifically, in step S1, before loading the steel cage, the first driving device 250 drives the rotating rod 240 to rotate in the counterclockwise direction in the figure, and the rotation of the rotating rod 240 drives the supporting platform 210 to descend; at this time, a pair of first clamps 310 are controlled to move away from each other by two cylinders, and the positioning support rod 410 is driven to a horizontal state by the second driving device 420, that is, the positioning assembly 400 is driven to be in the first state, and at the same time, the second clamp 442 is controlled to open by the third driving device 453.

[0118] S2: When one end of the steel cage is placed on the upper cage assembly 200 , the upper cage assembly 200 is controlled to lift the steel cage, and the upper cage assembly 200 is controlled to transfer the steel cage to the other end of the support base 100 through the positioning assembly 400 .

[0119] Specifically, in step S2, after the steel cage is placed on the support platform 210, the first driving device 250 drives the rotating rod 240 to rotate in the clockwise direction in the figure, so that the support platform 210 lifts the steel cage; after the steel cage is lifted, the conveyor belt 220 is started to drive the steel cage to move towards the lower cage assembly 500 under the support of the second clamp 442 under the drive of the conveyor belt 220. During this period, the roller 443 on the second clamp 442 plays a role in reducing the friction during the transmission of the steel cage.

[0120] S3: Control the lower cage assembly 500 to grab the steel cage.

[0121] Specifically, in step S3, when the steel cage moves to be sleeved on the outside of the clamping mechanism 520, the fourth driving device 522 drives a pair of adjusting racks 523 to move, and then drives a pair of grab hooks 524 to move to grab the steel cage. At this time, the wire rope reel 532 is in a tightened state, and the mounting seat 521 is close to the fixed plate 510.

[0122] S4: Control the positioning assembly 400 to switch to the second state so that the steel cage is aligned with the pile hole.

[0123] Specifically, in step S4, after the grab hook 524 fixes the steel cage, the second clamp 442 is first driven by the third driving device 453 to clamp to fix the steel cage, and then the positioning support rod 410 is driven by the second driving device 420 to be placed in a vertical state so that the steel cage is aligned with the pile hole position.

[0124] S5: Control the lower cage assembly 500 to lower the steel cage, and control the fixed cage assembly 300 to fix the rear end of the steel cage when the steel cage is lowered into the pile hole.

[0125] Specifically, in step S5, the second clamp 442 is driven to open by the third driving device 453, and then the steel cage is lowered by loosening the wire rope coil 532. After the steel cage is lowered into the pile hole, the first clamp 310 is driven by the cylinder to clamp the top of the steel cage in the pile hole.

[0126] S6: Repeat the above steps S1-S4 to align the front end of the reinforcement cage that has not been placed in the pile hole with the rear end of the reinforcement cage that has been lowered into the pile hole to facilitate welding of the reinforcement cage.

[0127] Specifically, in step S6, the above steps are repeated to lower the second section of the steel cage in the same manner. It should be noted that after the second section of the steel cage is lowered to dock with the first section of the steel cage in the pile hole, the transmission rod 535 can be driven to rotate by the fifth driving device 536, thereby driving the disc 531 to rotate, and then the second section of the steel cage is rotated by the driving action of the wire rope reel 532, thereby aligning the second section of the steel cage with the first section of the steel cage. Then the second section of the steel cage and the first section of the steel cage can be welded. After welding, the steel cage can be further lowered by the wire rope reel 532. After lowering, the steel cage continues to be fixed by the first clamp 310 to facilitate subsequent welding until the steel cage is placed at the bottom of the pile hole.
