Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to an integrated device for manufacturing, bidirectional flipping and lifting of a rectangular steel cage and a method for using the device. Background Art

[0002] Reinforced concrete structure is the main material used in current construction. Concrete has high compressive strength but very low tensile strength. It is usually used in conjunction with a steel cage to play a tensile role and enhance the strength of the overall structure. In the construction of ground-connected walls, the ground-connected wall steel cage (rectangular steel cage) should be hoisted immediately after it passes the acceptance inspection and the slot section hole cleaning and slurry replacement meets the requirements. During construction, a construction platform is first set up at the construction site. Then, according to the distance between two adjacent main bars, lines are drawn on the construction platform to mark the position of the main bars. Then, horizontal bars that are set perpendicular to the main bars are fixed and connected to the main bars to make a rectangular steel cage. After the rectangular steel cage is completed, it needs to be flipped and lifted. Usually, two lifting devices are used to flip the rectangular steel cage from a horizontal state to a vertical state. Then, one lifting device needs to be removed and the other lifting device is used to move the steel cage and transport it into the slot section. This method of operation, on the one hand, uses two lifting devices solely to adjust the cage's posture, increasing construction costs. On the other hand, the posture adjustment process requires the installation of lifting points on the cage, which results in uneven force on the cage and can easily damage it. The two lifting devices need to work together, requiring real-time communication during the lifting process, resulting in low efficiency. Furthermore, the production, flipping, and lifting of the rectangular cage require different tooling equipment, resulting in high construction costs and low efficiency. Summary of the Invention

[0003] The purpose of the present invention is to provide an integrated device for manufacturing, bidirectional flipping and lifting of rectangular steel cages and a method for use. The device can assemble, support, flip as a whole, and perform integrated lifting operations on rectangular steel cages. It has a simple and compact structure, is easy to operate, has strong detachability, high operating effect, reduces construction costs, and has broad application prospects.

[0007] Preferably, a limiting chain is provided between the rectangular supporting base plate and the supporting frame, and the limiting chain limits the rotation angle of the supporting frame to no more than 90°.

[0008] Preferably, one of the rotating shafts is fixedly provided on both sides of the support frame, and one of the gears is fixedly provided at both ends of the rotating shaft; the support frame is a rectangular structure formed by splicing a plurality of transverse fixed support rods and longitudinal fixed support rods.

[0012] Preferably, the linear drive mechanism is a hydraulic cylinder.

[0013] Preferably, two sliding rods are arranged in parallel and at intervals, and two fixing seats are arranged at intervals.

[0014] A method for using an integrated device for manufacturing, bidirectional flipping and lifting a rectangular steel cage, the method comprising the following steps:

[0015] Step 1: Equipment installation: first place the bidirectional flip platform in the preset position, and then place the production and lifting platforms according to the direction to be flipped;

[0016] Step 2: Fabricate the steel cage. Adjust the spacing between two adjacent limit assemblies according to the spacing of the main bars of the rectangular steel cage to be fabricated. Then, place the main bars on the limit assemblies, set up the ring bars, and assemble the entire rectangular steel cage.

[0017] Step 3: Flip the steel cage. After the rectangular steel cage is completed, remove the limit assembly, adjust the rotation of the rotating rod by rotating the driving assembly, and adjust the clamping assembly by rotating the driving assembly to clamp the rectangular steel cage and install it on the production and lifting platform; then start the driving assembly to adjust the posture of the production and lifting platform;

[0018] Step 4: Lift the steel cage. After the production and lifting platform is adjusted to a vertical state, the production and lifting platform and the rectangular steel cage installed thereon are lifted by the lifting equipment and lowered into the designated slot section.

[0019] In the present invention, the bidirectional flipping platform is used in conjunction with the production and lifting platform to integrate the production, flipping, and lifting of the steel cage, reducing the tedious construction steps of the traditional steel cage from production to the lower trough section, simplifying the tooling and hoisting equipment used in the steel cage construction operation, and saving construction costs. The bidirectional flipping platform is capable of rotating in two opposite directions. During the flipping operation, the steel cage can be flipped in two different directions according to needs, thereby improving the convenience of the operation. The limit chain is capable of limiting the flipping angle of the support frame, preventing excessive flipping and improving the safety of the operation.

[0020] During operation, different numbers of support units can be assembled according to the size of the rebar cage to be fabricated, making assembly and disassembly easy. The limiter components installed on the fabrication and lifting platform not only limit the position of the rebar placed on the support units to prevent displacement during the fabrication process, but also fix them according to the designed dimensions to ensure the consistency of the rebar cage size. The scale markings provide easy positioning of the limiter components, eliminating the need for additional measuring tools during position adjustment and improving work efficiency.

[0021] The clamping assembly provided on the production and lifting platform can connect the rectangular steel cage more evenly, so that the rectangular steel cage is evenly stressed during the lifting process to avoid damage. The rotating drive assembly provided can control the rotation angle of the rotating rod to achieve the connection and separation of the production and lifting platform and the rectangular steel cage. The multiple clamping diagonal rods provided can use gravity to clamp the production and lifting platform to the two-way flip platform when the two-way flip platform drives the production and lifting platform to adjust its posture, and can quickly separate from the two-way flip platform when the production and lifting platform is lifted.

DETAILED DESCRIPTION

[0028] The present invention will be further described below with reference to the accompanying drawings:

[0029] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The rectangular steel cage manufacturing, bidirectional flipping and lifting integrated equipment shown includes a bidirectional flipping platform 1 and a manufacturing and lifting platform 2 movably arranged on the bidirectional flipping platform 1. The bidirectional flipping platform 1 can drive the manufacturing and lifting platform 2 to swing and adjust its posture.

[0030] The bidirectional flip platform 1 includes a rectangular support base 10, a support 11 fixed on the rectangular support base 10 by fasteners, a support assembly 12 movably mounted on the support 11, and a drive assembly 13 arranged on both sides of the rectangular support base 10 for driving the support assembly 12 to rotate.

[0031] The support assembly 12 includes a support frame 120, a rotating shaft 121 fixedly mounted on either side of the support frame 120, and gears 122 fixedly mounted on each end of the rotating shaft 121. In one embodiment, a support 11 is fixedly mounted at each of the four corners of the rectangular support base 10. A semicircular groove is provided on the top of the support 11 to mate with the rotating shaft 121. The rotating shaft 121 is positioned within the semicircular groove and can rotate therein. A rotating shaft 121 is fixedly mounted on each side of the support frame 120, and a gear 122 is fixedly mounted at each end of the rotating shaft 121. In one specific embodiment, the support frame 120 is a rectangular structure formed by splicing together multiple horizontal and vertical fixed support rods.

[0032] The drive assembly 13 includes a fixed base 130 fixedly mounted on the rectangular support base 10, a slide rod 131 slidably mounted on the fixed base 130, a connecting block 132 fixedly mounted at both ends of the slide rod 131, a rack 133 mounted on the connecting block 132, and a linear drive mechanism 134 for driving the slide rod 131 to move. When the linear drive mechanism 134 drives the slide rod 131 to move back and forth, causing the rack 133 to engage with the gear 32, the rotating shaft 31 rotates around the semicircular groove on the upper part of the support 11 to achieve flipping. In one embodiment, a through hole is opened on the fixed base 130, and two slide rods 131 are arranged in parallel and spaced apart and respectively pass through the through holes, and two fixed bases 130 are arranged at intervals. In a specific embodiment, the linear drive mechanism 134 is a hydraulic cylinder. Under normal conditions, the piston rod of the hydraulic cylinder is in a half-extended state. When the hydraulic cylinder is extended or retracted, the support frame 120 rotates in different directions. In a preferred embodiment, two limiting chains 14 are installed between the rectangular support base 10 and the support frame 120. These limit chains 14 restrict the support frame 120 from rotating at an angle of no more than 90°. When the support frame 120 is tilted to a vertical position, one of the limiting chains 14 is in a taut state. For safety reasons, four, six, or eight limiting chains 14 may also be installed on both sides of the support frame 120.

[0033] The manufacturing and lifting platform 2 includes a plurality of support units 20 detachably connected by connectors 3, a limit assembly 21 detachably provided on the support units 20, and a clamping assembly 22 movably mounted on the support units 20. The support units 20 are composed of a plurality of parallel and spaced transverse support rods 200 and a rotating rod 201 movably mounted on the plurality of transverse support rods 200. In one embodiment, the transverse support rods 200 are made of I-beams, and an opening is provided on the web of the I-beam, through which the rotating rod 201 passes. Specifically, a pin or screw is provided on the rotating rod 201 to limit its relative position with the transverse support rod 200. Connecting holes are provided at both ends of the transverse support rods 200, through which the connector 3 passes to detachably connect two adjacent support units 20.

[0034] A rotation drive assembly 23 is mounted on the support unit 20 for controlling the rotation angle of the rotating rod 201. The rotation drive assembly 23 includes a driven sprocket 230 fixed to the end of the rotating rod 201, a drive sprocket 231 rotatably mounted on the support unit 20 via a rotating shaft, and a chain 232 that dynamically connects the driven sprockets 230 and the drive sprocket 231. When the drive sprocket 231 is rotated, the chain 232 drives all the driven sprockets 230 to rotate simultaneously, thereby rotating the rotating rod 201. In one embodiment, a handle is mounted on the drive sprocket 231 for driving the drive sprocket 231. In a preferred embodiment, the rotating shaft connecting the drive sprocket 231 is connected to the transverse support rod 200 via a one-way bearing, so that the drive sprocket 231 can only rotate in one direction. When the rectangular reinforcement cage is lowered to the specified position, the platform is further lowered, and then the drive sprocket 231 is rotated to separate the clamping assembly 22 from the rectangular reinforcement cage.

[0035] The clamping assembly 22 can clamp and install the rectangular steel cage on multiple supporting units 20. The clamping assembly 22 includes a connecting sleeve 220 and a supporting diagonal rod 221 fixedly installed on the connecting sleeve 220. The connecting sleeve 220 can be detachably installed on the rotating rod 201 by pins or screws. When the rotating rod 201 rotates, the clamping assembly 22 rotates accordingly.

[0036] A connecting groove 4 is provided on the transverse support rod 200, and a limiting assembly 21 for adjusting the position of the steel bar is detachably mounted on the connecting groove 4. A scale mark 5 is provided on the transverse support rod 200 on one side of the connecting groove 4. In one embodiment, the limiting assembly 21 includes a support base plate 210, two limiting plates 211 provided above the support base plate 210, a threaded rod 212 fixedly provided on the lower side of the support base plate 210, and a locking nut 213 provided on the threaded rod 212. The two limiting plates 211 can be fixed to the connecting groove 4 by screwing the locking nut 213. During operation, the positions of the multiple limiting assemblies 21 are limited according to the scale mark 5. The main reinforcement for making a rectangular steel cage is placed between the two limiting plates 211 to limit its position. During actual operation, two limiting plates 211 with different spacings can be selected according to the diameter of the steel bar to ensure the accuracy of the main reinforcement position limitation.

[0037] A plurality of clamping diagonal rods 6 are fixedly installed on the supporting unit 20, and one cantilevered end of the clamping diagonal rod 6 is clamped on the supporting frame 120. When the bidirectional flipping platform 1 drives the production and lifting platform 2 to adjust its posture, the clamping diagonal rod 6 uses gravity to clamp the production and lifting platform 2 to the bidirectional flipping platform.

[0038] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5The method for using the device for manufacturing, bidirectional flipping and lifting a rectangular steel cage shown in the figure comprises the following steps:

[0039] Step 1: Equipment installation. First, place the two-way flip platform 1 in the preset position, and use anchor bolts or other fastening equipment to fix the rectangular support base plate 10 to the ground. The rectangular support base plate 10 needs to be installed on a relatively flat and solid ground. After the installation is completed, the horizontality of the rectangular support base plate 10 needs to be measured. Only when it meets the design requirements can the installation be continued; then place the production and lifting platform 2 according to the direction to be flipped, and make a preliminary connection between the two by snapping on the diagonal rod 6.

[0040] Step 2: Fabricate the reinforcement cage. The spacing between two adjacent stopper assemblies 21 is adjusted based on the spacing of the main reinforcement in the rectangular reinforcement cage to be fabricated. When adjusting and securing the stopper assemblies 21, the scale marks 5 are used to quickly locate the position of the stopper assemblies 21, eliminating the need for other measuring tools and improving installation efficiency. The main reinforcement is then placed between the two stopper plates 211 of the stopper assemblies 21. Ring reinforcement is then installed, completing the assembly and fabrication of the entire rectangular reinforcement cage.

[0041] Step 3: Flip the Rebar Cage. After the rectangular rebar cage is completed, remove the limit assembly 21 and rotate the drive assembly 23 to adjust the rotation of the rotating rod 201, so that the supporting diagonal rod 221 in the clamping assembly 22 engages with the main reinforcement of the rectangular rebar cage, thereby completing the installation of the rectangular rebar cage on the fabrication and lifting platform 2. Then, activate the drive assembly 13 to flip the support assembly 12 in the specified direction, thereby adjusting the posture of the fabrication and lifting platform 2 and the rectangular rebar cage fixed thereon.

[0042] Step 4: Lifting the steel cage. After the production and lifting platform 2 is adjusted to a vertical state or other designed state, stop the action of the drive component 13, cooperate with the lifting equipment in the site to lift the production and lifting platform 2 and the rectangular steel cage installed thereon and lower them into the designated slot section. When the rectangular steel cage is installed in place, continue to lower it so that the wire rope of the lifting equipment is in a loose state. At this time, adjust the clamping component 22 by rotating the drive component 23 to separate the rectangular steel cage and the production and lifting platform 2. Lift the production and lifting platform 2 by the lifting equipment and transport it to the designated location for reuse. At this point, the production, flipping and lifting operation of the rectangular steel cage is completed once. Repeat the above steps until all rectangular steel cages are completed.

[0043] The above embodiments are merely some illustrations of the concept and implementation of the present invention, and are not intended to limit the same. Under the concept of the present invention, technical solutions that have not been substantially changed are still within the scope of protection.
