Description

Technical Field

[0001] This invention relates to the field of cast-in-place pile construction, and in particular to a device for stacking and hoisting reinforcing cages for cast-in-place piles. Background Technology

[0002] Drilled cast-in-place piles are one of the most widely used forms of foundation pit support engineering, particularly in deep foundation pit projects. This support method is highly adaptable, suitable for various geological conditions such as sandy soil and cohesive soil, and boasts advantages such as high bearing capacity, good deformation control, and low construction noise. It effectively resists lateral soil pressure, protecting surrounding buildings and underground pipelines. However, the construction quality of the reinforcing cage directly affects the stress performance and bearing capacity of the drilled cast-in-place pile. Currently, the main construction process for hoisting and splicing the reinforcing cage is as follows: The pile driver manually installs hooks on one end of the reinforcing cage; the pile driver starts the winch to hoist the reinforcing cage obliquely upwards from the stockpile area to the pile hole position, from a horizontal position to a vertical position; finally, after the pile driver lowers the reinforcing cage, it inserts a retaining rod for suspension, and then the hook is removed. However, the existing construction method has several problems:

[0003] Site issues: After the steel reinforcement cages are transported to the vicinity of the corresponding cast-in-place pile holes, they are placed haphazardly on the unhardened soil. The steel reinforcement cages are highly susceptible to dust contamination, and the dirt and moisture on the steel reinforcements accelerate corrosion. Furthermore, the uneven site causes the steel reinforcement cages to deform during storage.

[0004] Stacking issues: Randomly stacking on the ground takes up a large area, requires secondary manual handling and sorting, makes on-site management difficult, and can easily lead to incorrect steel cage type when multiple pile foundations are being constructed simultaneously.

[0005] Lifting issues; dragging one end of the steel cage from the ground during lifting can cause deformation of the end steel bars and even serious quality problems such as detachment of the spiral stirrups.

[0006] Quality issues: During the hoisting and lowering of the rebar cage, the model and rebar parameters are rarely checked, making it difficult to verify the finished quality of the rebar cage. It relies heavily on brief manual visual inspection, which easily leads to the omission of quality issues such as the model of the rebar cage and the length of the rebar joints. Summary of the Invention

[0007] The purpose of this invention is to provide a stacking device and hoisting method for cast-in-place pile reinforcement cages, so as to solve the problem that the service life and finished product quality of cast-in-place pile reinforcement cages are affected by the stacking site when they are stacked on the construction site due to pollution, corrosion and deformation.

[0008] To address the aforementioned technical problems, this invention provides a pile reinforcement cage stacking device, comprising an open-top support frame consisting of a base frame and end frames connected at both ends along its length, and side frames connected at both ends along its width. A barrier wheel, rotatably connected to the open-top support frame along its length, is located within the open-top support frame. The barrier wheel includes an axle rotatably connected to the open-top support frame and multiple coaxially spaced discs on it. Each disc includes radially distributed wheel rods connected to wheel rings, with the wheel rods extending beyond the wheel rings. Any two adjacent wheel rods and the wheel ring between them constitute an assembly station. The barrier wheel and the side frames form a receiving space. An arc-shaped support plate is positioned on the center line of the bottom length of the open-top support frame, with both sides of the arc-shaped support plate abutting against the side frames on both sides.

[0009] Furthermore, the pile reinforcement cage stacking device provided by the present invention further includes:

[0010] A guide rail is disposed along the length of the arc-shaped support plate and extends out of one end of the open-type support frame;

[0011] The top seat is slidably mounted on the guide rail and is detachably connected to the end axis of the cast-in-place pile reinforcement cage that is rotated onto the arc-shaped support plate.

[0012] The top rod, located at one end of the open-type support frame, is aligned with the axis of the cast-in-place pile reinforcement cage that is rotated onto the arc-shaped support plate. It is used to push the cast-in-place pile reinforcement cage on the arc-shaped support plate out of the open-type support frame onto the guide rail via the top seat.

[0013] Furthermore, in the cast-in-place pile reinforcement cage stacking device provided by the present invention, the top seat is a two-stage stepped bearing seat composed of two shafts with gradually increasing or decreasing diameters. The smaller diameter shaft of the two-stage stepped bearing seat is used to insert and connect into the inner diameter of the cast-in-place pile reinforcement cage. The end face of the larger diameter shaft of the two-stage stepped bearing seat abuts against and is magnetically connected to the end face of the cast-in-place pile reinforcement cage. The larger diameter shaft and the connected portion of the smaller diameter shaft are provided with through guide grooves for sliding and angular rotation on the guide rail.

[0014] Furthermore, in the cast-in-place pile reinforcement cage stacking device provided by the present invention, the top rod is a hydraulic jack.

[0015] Furthermore, the pile reinforcement cage stacking device provided by the present invention further includes:

[0016] Industrial cameras are symmetrically arranged on the two side frames of the open support frame or symmetrically arranged on the outside of the open support frame parallel to its length direction.

[0017] Furthermore, the pile reinforcement cage stacking device provided by the present invention further includes:

[0018] Wheels are mounted on the base frame.

[0019] Furthermore, in the cast-in-place pile reinforcement cage stacking device provided by the present invention, the side frame is a plate or a frame.

[0020] Furthermore, in the cast-in-place pile reinforcement cage stacking device provided by the present invention, the guide rails are two parallel rails.

[0021] To solve the above-mentioned technical problems, the present invention also provides a method for hoisting a reinforcing cage for cast-in-place piles, employing the aforementioned reinforcing cage stacking device for cast-in-place piles, comprising:

[0022] The steel cage stacking device for cast-in-place piles is arranged on the construction site of the cast-in-place piles, with the guide rail extending outward from the outside of the open-type support frame close to the pile hole of the cast-in-place pile, and the top rod is arranged at the end of the open-type support frame away from the pile hole.

[0023] After the tied-up reinforcing cage of the cast-in-place pile is transported to the construction site, the reinforcing cage is hoisted and positioned between two adjacent wheel rods of each disc of the barrier wheel through the top opening of the open-type support frame, and supported on an assembly station formed by the wheel rings between the wheel rods.

[0024] By rotating the barrier wheel, the cast-in-place pile steel cage loaded at the assembly station at the top opening of the open support frame is rotated against the inner wall of the side frame towards the arc-shaped support plate and housed in the housing space of the side frame, and the next empty assembly station is exposed at the top opening of the open support frame. By switching the assembly station, multiple cast-in-place pile steel cages are rotated and stacked at the assembly station of the barrier wheel and housed in the housing space of the side frame.

[0025] By rotating the barrier wheel, the cast-in-place pile steel cage housed in the side frame of the open support frame is lowered into the arc-shaped support plate and onto the guide rail above it.

[0026] Connect the top seat to the end face of the cast-in-place pile reinforcement cage on the side away from the pile hole. Start the top rod to push the cast-in-place pile reinforcement cage on the arc-shaped support plate and guide rail out onto the guide rail outside the open support frame through the top seat.

[0027] The end of the cast-in-place pile reinforcement cage on the guide rail that is close to the pile hole is connected by a hoisting device. The hoisting device lifts the end of the cast-in-place pile reinforcement cage that is close to the pile hole and makes the end of the cast-in-place pile reinforcement cage that is away from the pile hole slide along the guide rail through the top seat and rotate the angle so that the cast-in-place pile reinforcement cage transitions from a horizontal state, an inclined state to a vertical state on the guide rail.

[0028] The vertically positioned reinforcing cage of the cast-in-place pile is detached from its top seat, and the hoisted reinforcing cage is lowered into the pile hole using hoisting equipment.

[0029] Furthermore, the method for hoisting the reinforcing cage of the cast-in-place pile provided by the present invention uses industrial cameras symmetrically arranged on the two side frames of the open-type support frame or symmetrically arranged on the outside of the open-type support frame parallel to the length direction of the open-type support frame to detect the finished quality of the reinforcing cage of the cast-in-place pile loaded on the assembly station.

[0030] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0031] The present invention provides a stacking device and hoisting method for cast-in-place pile reinforcement cages. During the construction of cast-in-place piles, the reinforcement cages are placed on the construction site. By rotating and stacking the reinforcement cages at the assembly station where they are placed, multiple reinforcement cages can be stacked simultaneously. This facilitates management and categorized stacking by type, avoiding chaotic stacking on site. It also prevents the reinforcement cages from being directly stacked on the construction site, which is susceptible to dust pollution, dirt, moisture leading to accelerated corrosion, and deformation due to uneven construction site conditions. At the same time, it saves stacking space, ensures the quality of the finished reinforcement cages, and improves their service life.

[0032] The present invention provides a pile reinforcement cage stacking device and hoisting method, which uses an open-type support frame as a rotating frame for the isolation wheel. The pile reinforcement cage is stacked at an assembly station formed by any two adjacent wheel rods of the isolation wheel and the wheel ring between them. At the same time, by rotating the isolation wheel relative to the open-type support frame, the pile reinforcement cage loaded at the assembly station is housed in the space within the side frame of the open-type support frame. By rotating the isolation wheel, the pile reinforcement cage is sequentially lowered along the side frame onto the arc-shaped support plate and the guide rail on it. This allows the top rod to push the pile reinforcement cage out of the arc-shaped support plate and the open-type support frame along the guide rail through the top seat installed at the end of the pile reinforcement cage, thereby achieving the unloading of the pile reinforcement cage.

[0033] The present invention provides a method for hoisting reinforcing cages for cast-in-place piles. The reinforcing cage is hoisted from one end of the pile hole using hoisting equipment. A top seat rotates and slides along a guide rail, allowing the reinforcing cage to transition from a horizontal to an inclined state to a vertical state. The top seat is then detached from the reinforcing cage, aligning it with the pile hole before lowering it. The method utilizes the sliding and rotating angle of the top seat along the guide rail to lift the reinforcing cage, solving the problem of deformation caused by the lower end of the reinforcing cage directly resting on the ground in traditional methods. A rotating barrier disc is used to stack and transfer the reinforcing cage to an arc-shaped support plate. A top rod is then used to move the unloaded reinforcing cage onto the arc-shaped support plate horizontally along the guide rail to the pile hole, reducing the on-site hoisting path and improving hoisting efficiency.

[0034] The method for hoisting reinforcing cages for cast-in-place piles provided by this invention reduces the need for secondary handling at the construction site by synchronously moving the reinforcing cage stacking device and the pile driving equipment. Attached Figure Description

[0044] The present invention will now be described in detail with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0045] Please refer to Figures 1 to 5This invention provides a pile reinforcement cage stacking device 100, comprising an open-top support frame 110 consisting of a base frame 111, end frames 112 connected to both ends along its length, and side frames 113 connected to both ends along its width. An isolation wheel 120 is rotatably connected to the open-top support frame 110 along its length. The isolation wheel 120 includes an axle 121 rotatably connected to the open-top support frame 110 and multiple coaxially spaced discs 1. 22. The disc body 122 includes radially distributed wheel rods 122-1 and wheel rings 122-2 connected to them. The wheel rods 122-1 extend out of the wheel rings 122-2. Any two adjacent wheel rods 122-1 and the wheel rings 122-2 between them constitute an assembly station. The barrier disc 120 and the side frame 113 form a receiving space. An arc-shaped support plate 130 is set on the bottom centerline of the open support frame 110. The two sides of the arc-shaped support plate 130 are attached to the side frames 113 on both sides. The base frame 111 can be a planar frame or a planar plate. The end frame 112 can be a triangular frame or a rectangular frame. The side frame 113 can be a plate or a frame. The inner wall of the side frame 113 is arc-shaped. The gap between the side frame 113 and the barrier disc 120 forms a receiving space. The wheel axle 121 can be rotatably connected to the open support frame 110 through bearings. The wheel ring 122-2 is used to fix the radially distributed wheel rods 122-1 to ensure the angle at which they are connected to the wheel axle 121.

[0046] Please refer to this carefully. Figures 1 to 2 and Figure 4 The pile reinforcement cage stacking device 100 provided in this embodiment of the invention allows for the simultaneous stacking of multiple pile reinforcement cages 200 during pile construction. This facilitates management and categorized stacking by type, avoiding chaotic stacking on-site. It also prevents the pile reinforcement cages 200 from being directly stacked on the construction site, avoiding dust contamination, dirt, moisture leading to accelerated corrosion, and deformation due to unevenness. Furthermore, it saves stacking space, ensures the finished quality of the pile reinforcement cages 200, and improves their service life.

[0047] Please refer to this carefully. Figures 1 to 4 To facilitate the unloading of the cast-in-place pile reinforcement cage 200 stacked on the cast-in-place pile reinforcement cage stacking device 100, the cast-in-place pile reinforcement cage stacking device 100 provided in this embodiment of the invention may further include a guide rail 140, a top seat 150, and a top rod 160, wherein:

[0048] Guide rails 140 are disposed along the length of the arc-shaped support plate 130 and extend beyond one end of the open support frame 110. To improve stability, guide rails 140 may be two parallel rails.

[0049] A top seat 150 is slidably mounted on the guide rail 140 and is detachably connected to the end shaft of the cast-in-place pile reinforcement cage 200, which rotates onto the arc-shaped support plate 130. The figure illustrates top seats 150 in different positions; in practice, only one is needed. The top seat 150 can be a two-stage stepped bearing composed of two shafts with gradually increasing or decreasing diameters. The smaller diameter shaft 151 of the two-stage stepped bearing is inserted into the inner diameter of the cast-in-place pile reinforcement cage 200. The end face of the larger diameter shaft 152 of the two-stage stepped bearing abuts against and is magnetically connected to the end face of the cast-in-place pile reinforcement cage 200. The larger diameter shaft 152 and the connected portion of the smaller diameter shaft 151 are provided with through guide grooves 113 for sliding and tilting on the guide rail 140. The guide grooves 113 allow the top seat 150 to slide and tilt along the guide rail 140. When there are two guide rails 140, the top seat 150 can slide and rotate stably on the two guide rails 140.

[0050] A push rod 160, located at one end of the open-type support frame, is aligned with the axis of the cast-in-place pile reinforcement cage 200 rotated onto the arc-shaped support plate 130. It is used to push the cast-in-place pile reinforcement cage 200 from the arc-shaped support plate 130 onto the guide rail 140 extending beyond the open-type support frame via the top seat 150. The push rod 160 can be a hydraulic jack.

[0051] Please refer to this carefully. Figures 1 to 4 The pile reinforcement cage stacking device 100 provided in this embodiment of the invention uses an open-type support frame 110 as a frame to prevent the rotation of the wheel 120. The pile reinforcement cage 200 is stacked at the assembly station formed by any two adjacent wheel rods 122-1 of the wheel 120 and the wheel ring 122-2 between them. Simultaneously, by preventing the rotation of the wheel 120 relative to the open-type support frame 110, the pile reinforcement cage 200 loaded at the assembly station is contained within the open frame. Within the space of the side frame 113 of the support frame 110, the rotating blocking wheel 120 causes the cast-in-place pile reinforcement cage 200 to fall sequentially along the side frame 113 onto the arc-shaped support plate 130 and the guide rail 140 thereon. This allows the top rod 160 to push the cast-in-place pile reinforcement cage 200 out of the arc-shaped support plate 130 and the open support frame 110 via the top seat 150 installed at the end of the cast-in-place pile reinforcement cage 200 along the guide rail 140, thereby achieving the unloading of the cast-in-place pile reinforcement cage 200.

[0052] Please refer to this carefully. Figure 3To avoid selecting the wrong model of the cast-in-place pile reinforcement cage 200 and to inspect the finished product quality of the cast-in-place pile reinforcement cage 200, the cast-in-place pile reinforcement cage stacking device 100 provided in this embodiment of the invention may further include:

[0053] Industrial cameras 170 are symmetrically arranged on the two side frames 113 of the open-type support frame or symmetrically arranged on the outside of the open-type support frame 110 parallel to its length direction. The figure illustrates the case where they are symmetrically arranged on the outside of the pile-casting rebar cage stacking device 100. By capturing, scanning, and recording images in real time with the industrial cameras 170, the length and integrity of the pile-casting rebar cage 200 can be verified, and the welding quality of the rebar cage can be checked, effectively avoiding errors in the selection of the pile-casting rebar cage 200 model during construction.

[0054] Please refer to this carefully. Figure 3 To facilitate movement, the pile reinforcement cage stacking device 100 provided in this embodiment of the invention may further include:

[0055] Wheel 180 is mounted on the base frame 111. Wheel 180 can be a swivel caster.

[0056] Please refer to Figures 1 to 5 This invention also provides a method for hoisting a cast-in-place pile reinforcement cage 200, using the aforementioned cast-in-place pile reinforcement cage stacking device 100, comprising:

[0057] Step S1: Arrange the pile reinforcement cage stacking device 100 on the construction site of the pile, so that the guide rail 140 extending out of the open support frame 110 is close to the pile hole of the pile, and arrange the top rod 160 at the end of the open support frame 110 away from the pile hole.

[0058] Step S2: After transporting the tied cast-in-place pile reinforcement cage 200 to the construction site, the cast-in-place pile reinforcement cage 200 is hoisted and positioned between two adjacent wheel rods 122-1 of each disc body 122 of the barrier wheel 120 through the top opening of the open support frame 110, and supported on the wheel ring 122-2 between the wheel rods 122-1 to form an assembly station, that is, the cast-in-place pile reinforcement cage 200 is loaded on the assembly station.

[0059] In step S3, by rotating the barrier wheel 120, the cast-in-place pile reinforcement cage 200 loaded at the assembly station at the top opening of the open-type support frame 110 is rotated against the inner wall of the side frame 113 towards the arc-shaped support plate 130 and housed within the housing space of the side frame 113. This exposes the next empty assembly station at the top opening of the open-type support frame 110. By switching assembly stations, multiple cast-in-place pile reinforcement cages 200 are rotated and stacked at the assembly station of the barrier wheel 120 and housed within the housing space of the side frame 113. Only one side frame 113 is used to stack the cast-in-place pile reinforcement cage 200. The inner walls of both side frames 113 are arc-shaped, allowing the barrier wheel 120 to rotate in either direction, so that the cast-in-place pile reinforcement cage 200 can be housed within either side frame 113.

[0060] In step S4, by rotating the blocking wheel 120, the cast-in-place pile steel cage 200 contained in the side frame 113 of the open support frame 110 is lowered into the arc-shaped support plate 130 and onto the guide rail 140 thereon.

[0061] Step S5: Connect the top seat 150 to the end face of the cast-in-place pile reinforcement cage 200 on the side away from the pile hole, and start the top rod 160 to push the cast-in-place pile reinforcement cage 200 on the arc-shaped support plate 130 and guide rail 140 out onto the guide rail 140 outside the open-type support frame 110 through the top seat 150.

[0062] Step S6: Connect the end of the cast-in-place pile reinforcement cage 200 near the pile hole on the guide rail 140 through a hoisting device. Use the hoisting device to lift the end of the cast-in-place pile reinforcement cage 200 near the pile hole and make the end of the cast-in-place pile reinforcement cage 200 away from the pile hole slide along the guide rail 140 through the top seat 150 and rotate the angle so that the cast-in-place pile reinforcement cage 200 transitions from a horizontal state, an inclined state to a vertical state on the guide rail 140.

[0063] Step S7: Separate the vertically positioned cast-in-place pile reinforcement cage 200 from its top seat 150, and lower the hoisted cast-in-place pile reinforcement cage 200 into the pile hole using hoisting equipment.

[0064] The method for hoisting a cast-in-place pile reinforcement cage 200 provided in this embodiment of the invention involves lifting the cage 200, which is connected to one end of the pile hole, using hoisting equipment. The top seat 150 is rotated and slid along the guide rail 140, causing the reinforcement cage 200 to transition from a horizontal to an inclined state to a vertical state on the guide rail 140. The top seat 150 is then detached from the reinforcement cage 200, allowing the reinforcement cage 200 to be aligned with the pile hole and lowered. The top seat 150 is then used to guide the cage downwards. The sliding and flipping angle on the rail 140 lifts the cast-in-place pile reinforcement cage 200, solving the problem of deformation caused by the lower end of the traditional cast-in-place pile reinforcement cage 200 directly touching the ground. By rotating the isolation wheel 120, the cast-in-place pile reinforcement cage 200 is rotated, stacked, and transferred to the arc-shaped support plate 130. The top rod 160 is used to move the cast-in-place pile reinforcement cage 200, which is unloaded onto the arc-shaped support plate 130, horizontally along the guide rail 140 to the pile hole, reducing the on-site hoisting path and improving hoisting efficiency.

[0065] Please refer to this carefully. Figure 3 In the hoisting method for the reinforcing cage 200 of the cast-in-place pile provided in this embodiment of the invention, in step S3, the finished quality of the cast-in-place pile reinforcing cage 200 loaded on the assembly station can be detected by an industrial camera 170 symmetrically arranged on the two side frames 113 of the open-type support frame or symmetrically arranged on the outside of the open-type support frame parallel to the length direction of the open-type support frame 110. The finished quality includes, but is not limited to, the model, deformation, and welding quality of the cast-in-place pile reinforcing cage 200.

[0066] The method for hoisting the reinforcing cage 200 of a cast-in-place pile provided in this embodiment of the invention reduces the need for secondary handling at the construction site by synchronously moving the reinforcing cage stacking device 100 and the pile driving equipment 300. The hoisting equipment can be a tower crane, winch, etc.

By rotating the barrier wheel, the cast-in-place pile steel cage housed in the side frame of the open support frame is lowered into the arc-shaped support plate and onto the guide rail above it. Connect the top seat to the end face of the cast-in-place pile reinforcement cage on the side away from the pile hole. Start the top rod to push the cast-in-place pile reinforcement cage on the arc-shaped support plate and guide rail out onto the guide rail outside the open support frame through the top seat. The end of the cast-in-place pile reinforcement cage on the guide rail that is close to the pile hole is connected by a hoisting device. The hoisting device lifts the end of the cast-in-place pile reinforcement cage that is close to the pile hole and makes the end of the cast-in-place pile reinforcement cage that is away from the pile hole slide along the guide rail through the top seat and rotate the angle so that the cast-in-place pile reinforcement cage transitions from a horizontal state, an inclined state to a vertical state on the guide rail. The vertically positioned reinforcing cage of the cast-in-place pile is detached from its top seat, and the hoisted reinforcing cage is lowered into the pile hole using hoisting equipment.

10. The method for hoisting the reinforcing cage of a cast-in-place pile according to claim 9, characterized in that, The finished quality of the cast-in-place pile reinforcement cage loaded on the assembly station is detected by industrial cameras symmetrically arranged on the two side frames of the open support frame or symmetrically arranged on the outside of the open support frame parallel to the length direction of the open support frame.
