Description

Technical Field

[0001] This invention belongs to the field of building engineering technology, specifically a prestressed I-beam integrated lifting tool for steel reinforcement. Background Technology

[0002] Prestressed concrete beams are a common bridge construction method. Precast prestressed concrete beams need to be made on a special beam-making platform. Normally, the precast beam needs to be tied with steel bars, threaded and tensioned with prestressing tendons, installed with formwork, and poured with concrete in sequence on the platform. According to the construction process, the construction steps that must be carried out on the platform start from tensioning the prestressing tendons. If the steel bars of the beam can be tied outside the platform and the whole beam is hoisted to the beam-making platform, the production efficiency of the beam-making platform can be greatly improved.

[0003] Although there are many types of existing lifting tools, most of them are just changes in form and their functions have not changed much. The current lifting tools for prestressed I-beam reinforcement cannot be adjusted in position during actual use, resulting in poor practicality. At the same time, when fixing the prestressed I-beam reinforcement, the lifting tools are fixed to the prestressed I-beam reinforcement with straps, which makes them inconvenient and unstable. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated lifting device for prestressed I-beam reinforcement. A fixed motor drives a fixed gear, which, through belt drive, rotates three connecting gears, causing the fixed bidirectional threaded rod and two connecting bidirectional threaded rods to rotate. This, in turn, moves the lifting steel pipe and connecting steel pipe, moving two limiting plates. Simultaneously, the moving limiting plates move two fixing blocks, which in turn cause the support rod to slide within the support cylinder. This movement of the connecting blocks, in turn, causes the electric telescopic rod to move the connecting pipe. The connecting pipe slides within the support pipe and on the outer surface of the reinforcing rod. This device can simultaneously fix both ends of the prestressed I-beam reinforcement and adjust the length of the fixing mechanism, thus providing two functions and increasing its practicality. The motor rotates, causing one of the mounting gears to rotate. The meshing of two mounting gears causes the other mounting gear to rotate, which in turn causes two fixed bevel gears to rotate. The meshing of the fixed bevel gears and the connecting bevel gear causes the connecting bevel gear to rotate, which in turn causes the electric telescopic rod to rotate the connecting pipe and the support pipe until the connecting pipe and the support pipe are engaged at the bottom of the protruding part of the prestressed I-beam reinforcement. Then, the retraction of the electric telescopic rod causes the connecting pipe and the support pipe to fix the prestressed I-beam reinforcement. This allows for quick and stable clamping of the prestressed I-beam reinforcement, increasing its clamping stability and convenience.

[0005] The technical solution adopted in this invention is as follows: An integrated lifting device for prestressed I-beam reinforcement, comprising: a support block; an adjustment mechanism, the adjustment mechanism comprising an adjustment component, a rotating component, two lifting steel pipes, two sets of support components, four connecting steel pipes, and two limiting plates, wherein the two connecting steel pipes and one lifting steel pipe are slidably embedded in one side of the support block, the rotating component is disposed within the support block, the adjustment component is disposed on the rotating component, each set of support components is disposed on the four connecting steel pipes and the two lifting steel pipes, and both ends of each limiting plate are fixed between two connecting steel pipes; and a fixing mechanism, the fixing mechanism comprising a fixing box, a power component, two sets of rotating components, two sets of fixing components, and multiple sets of adsorption components, wherein the fixing box is fixedly connected to one side of the outer surface of one of the limiting plates, the power component is disposed within the fixing box, each set of rotating components is disposed on one side of the outer surface of two connecting steel pipes, each set of fixing components is disposed on the rotating component, and each set of adsorption components is disposed on the two sets of rotating components.

[0006] The rotating component includes two fixed plates, a fixed bidirectional threaded rod, and two connecting bidirectional threaded rods. Each fixed plate is fixedly connected to the inner wall of the support block. Both ends of the two connecting bidirectional threaded rods and the fixed bidirectional threaded rod are rotatably inserted through the two fixed plates. One end of each of the two lifting steel pipes is threaded onto the outer surface of the fixed bidirectional threaded rod, and the ends of the four connecting steel pipes are threaded onto the outer surface of the two connecting bidirectional threaded rods.

[0007] The adjusting component includes a fixed motor, a fixed gear, and three connecting gears. The fixed motor is fixedly connected to the support block. The fixed gear is fixedly sleeved on the output end of the fixed motor. Two of the connecting gears are fixedly sleeved on the outer surfaces of two connecting bidirectional threaded rods, and the other connecting gear is fixedly sleeved on the outer surface of the fixed bidirectional threaded rod. The fixed gear and the three connecting gears are driven by a toothed belt.

[0008] Each set of support components includes two supporting steel bars and three fixing steel bars. Two of the fixing steel bars and two of the supporting steel bars are fixedly connected between the lifting steel pipe and two connecting steel pipes, and the other fixing steel bar is fixedly connected between the two connecting steel pipes.

[0009] The power component includes a fixed rod, two fixed bevel gears, two mounting gears, and a mounting motor. The fixed rod is rotatably connected between the inner walls of the front and rear sides of the fixed box. The two fixed bevel gears are fixedly sleeved on the outer surface of the fixed rod. The mounting motor is fixedly connected to the lower inner wall of the fixed box. One of the mounting gears is fixedly sleeved on the output end of the mounting motor, and the other mounting gear is fixedly sleeved on the outer surface of the fixed rod. The mounting gear is located in the middle of the two fixed bevel gears, and the two mounting gears mesh with each other.

[0010] Each set of rotating components includes a connecting bevel gear, two fixed blocks, two support rods, and a support cylinder. One end of each fixed block is fixedly connected to the outer surface of one side of the connecting steel pipe. One end of each support rod rotatably passes through a fixed block. Both ends of the support cylinder are slidably sleeved on the outer surfaces of the two support rods. The connecting bevel gear is fixedly sleeved on one end of one of the support rods, and the connecting bevel gear and the fixed bevel gear mesh with each other.

[0011] Each set of adsorption components includes three mounting blocks, two locking blocks, and a first electromagnetic chuck. The inner surface of each mounting block is fixedly connected to the outer surface of the support rod, and the outer surface of each mounting block is provided with multiple connecting grooves. Each mounting block is slidably embedded between the inner walls of the support cylinder. The two locking blocks are movably embedded between the inner walls of the connecting grooves, and the first electromagnetic chuck is fixedly connected between the two locking blocks.

[0012] Each set of fixing components includes two connecting blocks, two electric telescopic rods, two connecting pipes, a support pipe, and two reinforcing rods. Each connecting block is fixedly sleeved on the outer surface of the support rod, each electric telescopic rod is fixedly connected to one side of the outer surface of the connecting block, the outer surface of each connecting pipe is fixedly connected to the extended end of the electric telescopic rod, both ends of the support pipe are slidably sleeved on the outer surfaces of the two connecting pipes, one end of each reinforcing rod is fixedly connected to the support pipe, and the other end of each reinforcing rod is slidably embedded between the inner walls of the connecting pipes.

[0013] The top of each of the two lifting steel pipes and the support block is fixedly connected with a lifting ring, and the bottom of the support block is fixedly embedded with a second electromagnetic chuck.

[0014] A method for using an integrated lifting tool for prestressed I-beam reinforcement includes the following steps:

[0015] Step 1: Adjust the lifting device: Turn on the fixed motor. The rotation of the fixed motor drives the fixed gear to rotate. Through the transmission of the toothed belt, the three connecting gears rotate, causing the fixed double-threaded rod and the two connecting double-threaded rods to rotate. This causes the lifting steel pipe and the connecting steel pipe to move the two limit plates. When the two limit plates move, they also drive the two fixed blocks to move, which in turn causes the support rod to slide in the support cylinder. At the same time, the connecting blocks move, which causes the electric telescopic rod to move the connecting pipe. The connecting pipe slides inside the support pipe and on the outer surface of the reinforcing rod. When the two limit plates move to the appropriate position, the fixed motor can be turned off.

[0016] Step 2: Adjust the adsorption components: Remove the clips on the multiple adsorption components from the connecting groove, and then adjust the position of the clips and the first electromagnetic chuck according to the actual length of the prestressed I-beam reinforcement. Then place the support block on top of the prestressed I-beam reinforcement, and use multiple first electromagnetic chucks and second electromagnetic chucks to adsorb the prestressed I-beam reinforcement. Then start the fixed motor to fix both ends of the prestressed I-beam reinforcement.

[0017] Step 3: Fixing the prestressed I-beam reinforcement: Turn on the installation motor. The rotation of the installation motor will cause one of the installation gears to rotate. Through the meshing of the two installation gears, the other installation gear will drive the fixing rod to rotate. The rotation of the fixing rod will cause the two fixed bevel gears to rotate. Through the meshing of the fixed bevel gears and the connecting bevel gears, the connecting bevel gears will drive the support rod to rotate. This will cause the electric telescopic rod to drive the connecting pipe and the support pipe to rotate until the connecting pipe and the support pipe are stuck at the bottom of the protrusion of the prestressed I-beam reinforcement. Then, the retraction of the electric telescopic rod will drive the connecting pipe and the support pipe to fix the prestressed I-beam reinforcement.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0019] (1) In this invention, the fixed motor rotates to drive the fixed gear to rotate, and the toothed belt drives the three connecting gears to rotate, which in turn drives the fixed bidirectional threaded rod and the two connecting bidirectional threaded rods to rotate. This causes the lifting steel pipe and the connecting steel pipe to move the two limiting plates. When the two limiting plates move, they also drive the two fixed blocks to move, which in turn drives the support rod to slide in the support cylinder. At the same time, the connecting blocks move, which causes the electric telescopic rod to drive the connecting pipe to move. The connecting pipe slides inside the support pipe and on the outer surface of the reinforcing rod. This allows the two ends of the prestressed I beam steel bars to be fixed while the length of the fixing mechanism can be adjusted. This has two functions and increases its practicality.

[0020] (2) In this invention, the installation motor can rotate one of the installation gears, and the meshing of the two installation gears can drive the fixed rod to rotate. The rotation of the fixed rod can drive the two fixed bevel gears to rotate. The meshing of the fixed bevel gears and the connecting bevel gears can drive the supporting rod to rotate, thereby causing the electric telescopic rod to drive the connecting pipe and the supporting pipe to rotate until the connecting pipe and the supporting pipe are stuck at the bottom of the protrusion of the prestressed I beam steel bar. Then, the retraction of the electric telescopic rod drives the connecting pipe and the supporting pipe to fix the prestressed I beam steel bar. The prestressed I beam steel bar can be quickly and securely fixed and clamped, increasing its clamping stability and convenience. Attached Figure Description

[0049] The following is a detailed description of the method of using an integrated lifting device for prestressed I-beam reinforcement provided by an embodiment of the present invention. The method of use includes the following steps: Step 1: Adjusting the lifting device: Turn on the fixed motor 202. The rotation of the fixed motor 202 drives the fixed gear 203 to rotate. Through the transmission of the toothed belt, the three connecting gears 204 can rotate, causing the fixed bidirectional threaded rod 205 and the two connecting bidirectional threaded rods 207 to rotate. This causes the lifting steel pipe 206 and the connecting steel pipe 208 to move the two limiting plates 211. When the two limiting plates 211 move simultaneously... The two fixed blocks 406 move, which in turn causes the support rod 413 to slide in the support cylinder 412, and at the same time causes the connecting block 407 to move, thereby causing the electric telescopic rod 408 to move the connecting pipe 409. The connecting pipe 409 slides inside the support pipe 410 and on the outer surface of the reinforcing rod 411. When the two limit plates 211 move to the appropriate position, the fixed motor 202 can be turned off. Step 2: Adjust the adsorption components: Remove the locking blocks 416 on the multiple adsorption components from the connecting groove 415, and then adjust the locking blocks according to the actual length of the prestressed I beam reinforcement. Position the support block 1 at the locations of 416 and the first electromagnetic chuck 417, then place the support block 1 on top of the prestressed I-beam reinforcement. The prestressed I-beam reinforcement is then held in place by multiple first electromagnetic chucks 417 and second electromagnetic chucks 5. The fixing motor 202 is then activated to fix both ends of the prestressed I-beam reinforcement. Step 3: Fixing the prestressed I-beam reinforcement: Turn on the installation motor 404. The rotation of the installation motor 404 causes one of the installation gears 405 to rotate. Through the meshing of two installation gears 405, the other installation gear 405 drives the fixing rod. Rotation of rod 402 causes two fixed bevel gears 403 to rotate. The meshing of fixed bevel gears 403 and connecting bevel gears 418 causes connecting bevel gears 418 to drive support rod 413 to rotate, thereby causing electric telescopic rod 408 to drive connecting pipe 409 and support pipe 410 to rotate until connecting pipe 409 and support pipe 410 are engaged at the bottom of the protrusion of the prestressed I beam reinforcement. Then, the retraction of electric telescopic rod 408 drives connecting pipe 409 and support pipe 410 to fix the prestressed I beam reinforcement.

[0050] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

6. A method for using an integrated lifting tool for prestressed I-beam reinforcement, characterized in that, The method of applying the integrated lifting device for prestressed I-beam reinforcement as described in claim 5 includes the following steps: S1. Adjusting the lifting device: Turn on the fixed motor (202). The fixed motor (202) rotates and drives the fixed gear (203) to rotate. Through the transmission of the toothed belt, the three connecting gears (204) rotate, causing the fixed double-threaded rod (205) and the two connecting double-threaded rods (207) to rotate. This causes the lifting steel pipe (206) and the connecting steel pipe (208) to move the two limit plates (211). When the two limit plates (211) move, they also drive the two fixed blocks (406) to move, which in turn drives the support rod (413) to slide in the support cylinder (412). At the same time, it drives the connecting block (407) to move, which causes the electric telescopic rod (408) to drive the connecting pipe (409) to move. The connecting pipe (409) slides inside the support pipe (410) and on the outer surface of the reinforcing rod (411). When the two limit plates (211) move to the appropriate position, the fixed motor (202) can be turned off. S2. Adjust the adsorption components: Take out the clips (416) on the multiple adsorption components from the connecting groove (415), and then adjust the position of the clips (416) and the first electromagnetic chuck (417) according to the actual length of the prestressed I beam steel bars. Then place the support block (1) on the top of the prestressed I beam steel bars, and adsorb the prestressed I beam steel bars through the multiple first electromagnetic chucks (417) and the second electromagnetic chucks (5). Then start the fixed motor (202) to fix the two ends of the prestressed I beam steel bars. S3. Fixing the prestressed I-beam reinforcement: Turn on the installation motor (404). The installation motor (404) rotates, causing one of the installation gears (405) to rotate. Through the meshing of the two installation gears (405), the other installation gear (405) drives the fixing rod (402) to rotate. Through the rotation of the fixing rod (402), the two fixing bevel gears (403) rotate. Through the meshing of the fixing bevel gear (403) and the connecting bevel gear (418), the connecting bevel gear (418) drives the support rod (413) to rotate. This causes the electric telescopic rod (408) to drive the connecting pipe (409) and the support pipe (410) to rotate until the connecting pipe (409) and the support pipe (410) are stuck at the bottom of the protrusion of the prestressed I-beam reinforcement. Then, through the retraction of the electric telescopic rod (408), the connecting pipe (409) and the support pipe (410) are driven to fix the prestressed I-beam reinforcement.
