Description

Technical Field

[0001] This utility model relates to the field of steel bar transportation technology, and in particular to a steel bar transportation support for building construction. Background Technology

[0002] During the construction of prestressed concrete simply supported beams, the handling of raw and semi-finished steel reinforcement materials in the beam yard is usually carried out by gantry cranes, forklifts, or manual labor to transfer the steel reinforcement.

[0003] For example, patent number CN201473216U discloses a rebar installation hanger, which uses a lifting device to first lift the rebar cage, making it easier for workers to tie the stirrups and insert the main bars. After the rebar cage is tied, it is then placed into the formwork using the lifting device. The position of the rebar cage can be adjusted at any time during the placement process to achieve the ideal position, thereby improving the success rate and quality of rebar cage installation. It is easy to operate, facilitates rebar modification, and can improve labor efficiency.

[0004] For example, patent number CN219708939U discloses a rebar tying and lifting tool. It uses a rope box to pull the steel wire rope downwards, allowing the connecting ring to move downwards. Then, it grasps the rotating ring and adjusts its position by rotating it back and forth. The rebar is hooked with hooks, and four hooks are used to hook the four corners of the rebar tying. Then, it grasps the limiting frame and rotates it. A threaded rod passes through the threaded holes of both the fixing plate and the limiting frame to restrict the limiting frame. After the rebar is tied on the ground, the lifting frame is used to lift the rebar tying. Before lifting the rebar tying, the position of the threaded post is adjusted, and then the position of the rotating ring can also be adjusted, thereby adjusting the position of the hooks. At this time, the position of the hooks is adjusted so that the hooks are inserted into the rebar tying. Then, the limiting frame is rotated and fastened to the top of the rebar. Then, the limiting frame is restricted and cannot rotate. At this time, when the lifted rebar is transferred in the air, the rebar cannot fall off the hooks, and the rebar tying cannot fall in the air.

[0005] However, during the transportation and transfer of steel bars, the existing steel bar transport racks are prone to cracking or breaking due to the heavy weight of the steel bars being transported and the long working time of the lifting ropes. Furthermore, the limiting mechanism of the steel bar transport racks lacks stability, posing certain safety hazards. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a steel bar transport support for construction engineering. It solves the problems of existing steel bar transport supports, which are prone to cracking or breaking on the surface of the lifting ropes due to the heavy weight of the steel bars being transported and the long working time of the lifting ropes. Furthermore, the limiting mechanism of the steel bar transport support is not stable enough, posing certain safety hazards.

[0007] The technical solution of this utility model is as follows: a steel bar transport support for construction engineering, including a device base, a guide frame fixedly connected to the top of the device base, a shelf movably connected to the inner side of the guide frame, a limit frame fixedly connected to the rear of the shelf at the rear end of the guide frame, a limit component fixedly connected to the top of the shelf, one end of the limit component extending to the inner side of the limit frame, the limit component being used for connection between the shelf and the limit frame, hooks fixedly connected to both sides of the top surface of the shelf, and hanging ropes provided on the inner side of the hooks, and the inner wall of the guide frame... A hanging ring is fixedly connected to the top of the device, and an infrared scanning device is installed on the inner wall of the hanging ring. A winding assembly is installed at the top of the device base behind the hanging rope. One end of the hanging rope extends to the inner side of the hanging ring and connects to the winding assembly. The limiting assembly includes a limiting seat, and limiting blocks are movably connected to both sides of the limiting seat. A cylinder is installed at the center of the top of the two limiting blocks. A pneumatic rod is fixedly connected to the output end of the cylinder, and a top block is fixedly connected to the bottom end of the pneumatic rod. When the cylinder drives the pneumatic rod to move, the pneumatic rod cooperates with the top block to push the limiting block out from the inner side of the limiting seat.

[0008] Preferably, a control panel is fixedly connected to one side of the guide frame. The control panel is electrically connected to the limiting component, the winding component, and the infrared scanning device. The limiting component, the winding component, and the infrared scanning device can be controlled by the control panel. The infrared scanning device includes three infrared scanning heads. When the hanging rope is wound and unwound by the winding component, the surface of the hanging rope is monitored by the infrared scanning device.

[0009] Preferably, the winding assembly includes a winding motor, the output end of which is fixedly connected to a winding shaft. One end of the hanging rope extends to the outside of the hanging ring and is wound around the outside of the winding shaft. The hanging rope can be wound up by the winding motor in conjunction with the winding shaft.

[0010] Preferably, guide grooves are provided on both sides of the inner wall of the guide frame, and the two sides of the shelf extend to the inner side of the guide groove. When the winding assembly drives the shelf to rise and fall, the shelf moves inside the guide groove.

[0011] Preferably, the inner side of the shelf has a storage groove, and the inner side of the storage groove has a strap hole, which can be used to fix the strap to the steel bar. The shelf and the limiting seat are integrated. The two sides of the limiting seat are provided with limiting grooves on the inner wall of the limiting shelf. When the cylinder drives the top block to move, the cylinder cooperates with the top block to make the limiting block insert into the inner side of the limiting groove.

[0012] Preferably, both sides of the top block are inclined surfaces, and the top of the limiting block is in contact with the inclined surface of the top block.

[0013] Preferably, the bottom end of the limiting block is provided with a movable groove on the inner side of the limiting seat, the bottom end of the limiting block extends to the inner side of the movable groove, and a contraction spring is fixedly connected to the inner wall of the movable groove. The limiting block is movably connected to the limiting seat through the contraction spring.

[0014] The beneficial effects of this utility model are:

[0015] This steel bar transport support for construction projects can achieve mechanical rigid locking by driving the limit component through a cylinder after the rack is raised and lowered to any designated position. This effectively prevents accidental slippage caused by slack ropes, motor failure, or external impact, greatly improving the reliability of equipment operation. In addition, the infrared scanning device on the inner wall of the hanging ring can monitor the surface condition of the hanging rope in real time. If the hanging rope shows cracks, wear, twisting, or breakage tendency, it will be linked to the control panel to automatically activate the limit component for emergency locking, forming a "monitoring-early warning-protection" closed loop, which significantly improves the inherent safety level of the equipment.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4This utility model provides an embodiment: a steel bar transport support for construction engineering, including a device base 1, a guide frame 2 fixedly connected to the top of the device base 1, a shelf 5 movably connected to the inner side of the guide frame 2, a limit frame 4 fixedly connected to the rear of the shelf 5 at the rear end of the guide frame 2, a limit component fixedly connected to the top of the shelf 5, one end of the limit component extending to the inner side of the limit frame 4, the limit component being used for connection between the shelf 5 and the limit frame 4, hooks 6 fixedly connected to both sides of the top surface of the shelf 5, and hanging ropes 7 provided on the inner side of the hooks 6, and a hanging rope 7 fixedly connected to the top of the inner wall of the guide frame 2. The inner wall of the ring 9 is equipped with an infrared scanning device 10. A winding assembly is located at the top of the device base 1 behind the hanging rope 7. One end of the hanging rope 7 extends to the inner side of the hanging ring 9 and connects to the winding assembly. The limiting assembly includes a limiting seat 8. Limiting blocks 15 are movably connected to both sides of the limiting seat 8. A cylinder 16 is located at the center of the top of the two limiting blocks 15. A pneumatic rod 17 is fixedly connected to the output end of the cylinder 16. A top block 18 is fixedly connected to the bottom end of the pneumatic rod 17. When the cylinder 16 drives the pneumatic rod 17 to move, the pneumatic rod 17 cooperates with the top block 18 to push the limiting block 15 out from the inner side of the limiting seat 8.

[0023] Please see Figures 1-2 In this embodiment, a control panel 3 is fixedly connected to one side of the guide frame 2. The control panel 3 is electrically connected to the limiting component, the winding component, and the infrared scanning device 10. The limiting component, the winding component, and the infrared scanning device 10 can be controlled by the control panel 3. The infrared scanning device 10 includes three infrared scanning heads. When the hanging rope 7 is wound and unwound by the winding component, the infrared scanning device 10 monitors the surface of the hanging rope 7. The winding component includes a winding motor 11, and the output end of the winding motor 11 is fixedly connected to a winding device. One end of the hanging rope 7 extends to the outside of the inside of the hanging ring 9 and is wound around the outside of the take-up shaft 12. The hanging rope 7 can be wound up by the take-up motor 11 in conjunction with the take-up shaft 12. Guide grooves are opened on both sides of the inner wall of the guide frame 2. A slider is set in the guide groove to reduce frictional resistance and improve the smoothness of operation. The guide groove is made of high-strength steel or aluminum alloy, which combines lightweight and durability. Buffer pads can be added to the top and bottom of the guide groove to prevent damage from overtravel. The two sides of the shelf 5 extend to the inside of the guide groove. When the take-up assembly drives the shelf 5 to rise and fall, the shelf 5 moves inside the guide groove.

[0024] Please see Figures 3-4In this embodiment, a storage groove 13 is provided on the inner side of the shelf 5, and a strap hole is provided on the inner side of the storage groove 13. The storage groove 13 is a U-shaped groove, which is conducive to fixing cylindrical steel bars and preventing them from rolling and slipping. The strap hole can be used to further fix the steel bars with nylon straps or steel wire ropes to improve transportation safety. The shelf 5 is made of welding or integral molding process to ensure structural rigidity. The shelf 5 and the limiting seat 8 are integral structures. Limiting grooves are provided on both sides of the limiting seat 8 on the inner wall of the limiting frame 4. 14. When the cylinder 16 drives the top block 18 to move, the cylinder 16 cooperates with the top block 18 to make the limiting block 15 insert into the inner side of the limiting groove 14. Both sides of the top block 18 are inclined surfaces. The top of the limiting block 15 is in contact with the inclined surface of the top block 18. The bottom end of the limiting block 15 is located inside the limiting seat 8 and has a movable groove. The bottom end of the limiting block 15 extends to the inner side of the movable groove. A contraction spring 19 is fixedly connected to the inner wall of the movable groove. The limiting block 15 is movably connected to the limiting seat 8 through the contraction spring 19.

[0025] During operation, place the device base 1 in a suitable position, connect the power supply, and start the device. Then, place the items to be transported into the storage slot 13 on the top surface of the storage rack 5. Since the storage slot 13 is a U-shaped slot, it is conducive to fixing cylindrical steel bars and preventing them from rolling and slipping. The strap holes can be used to further fix the steel bars with nylon straps or steel wire ropes to improve transportation safety. Then, start the winding motor 11 through the control panel 3. The winding motor 11 drives the winding shaft 12 to rotate. When the winding shaft 12 rotates, it, together with the hanging rope 7, drives the storage rack 5 to move inside the guide frame 2 and the limiting frame 4. The lifting motion facilitates the transportation of steel bars. When the shelf 5 stops at different positions, the cylinder 16 can be activated via the control panel 3. The cylinder 16, together with the air rod 17 and the top block 18, causes the limit block 15 to be inserted into the inner side of the limit groove 14, which facilitates locking the position of the shelf 5. When the hanging rope 7 is wound and unwound by the winding assembly, the surface of the hanging rope 7 is monitored by the infrared scanning device 10. If cracks or breaks are detected on the surface of the hanging rope 7, the limit assembly is quickly activated via the control panel 3 to lock the position of the shelf 5 and prevent safety hazards.

[0026] Compared to the prior art document CN201473216U, which describes a rebar installation hanger, this tool utilizes a lifting device to first lift the rebar cage, facilitating workers to tie stirrups and insert main reinforcement bars. After the rebar cage is tied, it is then lowered into the formwork using the lifting device. The position of the rebar cage can be adjusted during the lowering process to achieve the ideal position, improving the success rate and quality of rebar cage installation. It is also convenient to operate, facilitating rebar adjustment and increasing labor efficiency. Furthermore, compared to CN219708939U, which describes a rebar tying hanger tool, this tool allows adjustment of the threaded column position before lifting the rebar, followed by adjustment of the swivel ring position, which in turn adjusts the hook position. Once the hook is properly positioned, it is inserted into the rebar tie. Then, the limiting frame is rotated and fastened above the rebar, and then the limiting frame is restricted from rotating. At this time, when the suspended rebar is transferred in the air, the rebar cannot fall off the hook and is tied in the air. In this application, when the shelf is raised and lowered to any designated position, the limiting component can be driven by the cylinder to achieve mechanical rigid locking, which effectively prevents accidental slippage caused by slack hanging rope, motor failure or external impact, greatly improving the reliability of equipment operation. Moreover, the infrared scanning device on the inner wall of the hanging ring can monitor the surface condition of the hanging rope in real time. If the hanging rope has cracks, wear, twisting or breakage tendency, the control panel will be linked to automatically start the limiting component for emergency locking, forming a "monitoring-early warning-protection" closed loop, which significantly improves the inherent safety level of the equipment.

[0027] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
