Description

Technical Field

[0001] This utility model relates to the field of rebar straightening technology, and in particular to a rebar straightening device for building construction. Background Technology

[0002] Reinforcing bars are steel materials used to reinforce concrete. They are usually round steel bars or steel meshes and are widely used in construction engineering. Their main function is to improve the tensile strength of concrete, because concrete itself is relatively fragile when subjected to tensile forces. The combination of reinforcing bars and concrete can effectively improve the overall strength and stability of the structure. In construction engineering, reinforcing bars, as an important structural material, usually need to be shaped through cold or hot working to meet different construction needs. However, in actual construction, deformation, bending and other defects of reinforcing bars often lead to a decline in construction quality. Therefore, a reinforcing bar straightening device for construction engineering is needed.

[0003] In construction, steel bars come in various sizes, but most traditional steel bar straightening devices can only straighten bars of the same specification. When it is necessary to straighten steel bars of different thicknesses, different equipment needs to be replaced, which increases the cost of use and reduces the practicality and flexibility of the equipment. In addition, during the steel bar straightening process, friction is generated during the transport and straightening operation, resulting in iron dust on the surface of the steel bars. However, traditional steel bar straightening devices usually do not have effective dust removal functions, causing iron dust to fly everywhere. This iron dust not only affects the working environment but may also threaten the health of workers and pose safety hazards. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a steel bar straightening device for building construction.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A rebar straightening device for building construction includes an operating platform. A protective cover is fixed to one end of the top of the operating platform. Multiple through holes are symmetrically arranged on both outer side walls of the protective cover at equal intervals. A base is fixed to the top of the operating platform, located inside the protective cover. Multiple first connecting seats are equidistantly fixed to the top of the base, each with a first arc-shaped groove. Multiple second connecting seats are arranged on the top of the base floor, each with a second arc-shaped groove at its bottom, and the second arc-shaped grooves correspond one-to-one with the first arc-shaped grooves. A first lifting mechanism for raising and lowering the multiple second connecting seats is provided on the top of the protective cover. A dust removal mechanism for dust removal is also provided on the top of the protective cover. A conveying mechanism for conveying rebar is provided at the other end of the top of the operating platform. During use, the distance between the second and first connecting seats can be adjusted by the first lifting mechanism to clamp rebars of different thicknesses. The distance between the first and second conveying rollers can be adjusted by the second lifting mechanism to convey rebars of different thicknesses. This allows for straightening of rebars of different thicknesses without the need to replace equipment, reducing operating costs and improving equipment flexibility.

[0006] As a further embodiment of this utility model, the conveying mechanism includes two support plates, which are symmetrically fixed to the other end of the top of the operating table. Two sliding grooves are formed through the outer walls of each support plate. The inner walls of the two support plates are rotatably connected to the same first rotating shaft. A first conveying roller is sleeved on the side wall of the first rotating shaft. Multiple first grooves are equidistantly formed on the outer wall of the first conveying roller. A motor is fixed to the outer wall of one of the support plates, and the output shaft of the motor is fixed to the first rotating shaft via a coupling. The inner walls of the two sliding grooves are slidably connected to the same second rotating shaft. A second conveying roller is sleeved on the outer wall of the second rotating shaft. Multiple first grooves are equidistantly formed on the outer wall of the second conveying roller. Two grooves are provided, and multiple second grooves correspond one-to-one with multiple first grooves. The outer walls of both support plates are provided with a second lifting mechanism for raising and lowering the second conveying roller. The second lifting mechanism includes a support plate, which is fixed to the outer wall of one of the support plates. A second hydraulic push rod is fixed to the bottom of the support plate, and the output shaft of the second hydraulic push rod is rotatably connected to one end of the second rotating shaft. The two second hydraulic push rods are driven to simultaneously drive the second rotating shaft to rise or fall along the inside of the two slides, thereby driving the second conveying roller to gradually move away from or closer to the first conveying roller. The drive motor drives the first rotating shaft to rotate, thereby driving the first conveying roller to rotate. The rotation of the first conveying roller cooperates with the second conveying roller to convey the steel bars.

[0007] As a further embodiment of this utility model, the first lifting mechanism includes two first hydraulic push rods, which are symmetrically fixed at both ends of the top of the protective cover, and the output ends of the two first hydraulic push rods penetrate through the inside of the protective cover. A connecting plate is provided inside the protective cover, and the bottom of the connecting plate is fixed to a plurality of second connecting seats, while the top of the connecting plate is fixed to the output ends of the two first hydraulic push rods. Driving the two first hydraulic push rods in conjunction with the connecting plate drives the plurality of second connecting seats to rise or fall. Adjusting the distance between the second connecting seats and the first connecting seats allows for clamping of steel bars of different thicknesses.

[0008] As a further embodiment of this utility model, the dust removal mechanism includes a collection box, which is fixed to the middle of the top of the protective cover. A cover is installed on the top of the collection box, and a filter screen is fixed to the inner wall of the collection box. An exhaust fan is fixed to the top of the protective cover, and the air inlet of the exhaust fan is connected to the collection box. The exhaust fan is located below the filter screen. A sleeve is fixed to the inner wall of the protective cover. Multiple branch pipes are installed linearly at equal intervals on the outer wall of the sleeve, and all branch pipes are connected to the sleeve. A connecting pipe is installed through the outer wall of the collection box. One end of the connecting pipe is connected to the sleeve, and the other end of the connecting pipe is located above the filter screen. The exhaust fan is driven to evacuate the inside of the collection box, creating a negative pressure environment inside the collection box. In conjunction with the connecting pipe, a negative pressure environment is created inside the sleeve. Iron dust is drawn into the sleeve through the multiple branch pipes and falls onto the top of the filter screen through the connecting pipe for collection. This allows for unified collection and treatment of iron dust from steel bars, preventing iron dust from splashing everywhere and affecting the health of workers, thus improving the safety performance of this device.

[0009] The beneficial effects of this utility model are as follows: 1. During use, this device can clamp steel bars of different thicknesses by adjusting the distance between the second connecting seat and the first connecting seat through the first lifting mechanism. By coordinating the second lifting mechanism to adjust the distance between the first conveying roller and the second conveying roller, steel bars of different thicknesses can be conveyed. This allows for the straightening of steel bars of different thicknesses without the need to replace equipment, reducing operating costs and improving the flexibility of the equipment.

[0010] 2. The dust removal system can effectively collect the iron dust generated during the rebar straightening process, reducing the threat to workers' health, improving the construction environment, and enhancing safety performance. Attached Figure Description

The device is equipped with a first lifting mechanism for raising and lowering multiple second connecting seats 12, a dust removal mechanism for dust removal on the top of the protective cover 2, and a conveying mechanism for conveying steel bars at the other end of the top of the operating platform 1. During use, the distance between the second connecting seats 12 and the first connecting seat 21 can be adjusted by the first lifting mechanism to clamp steel bars of different thicknesses.

[0015] In this embodiment, the conveying mechanism includes two support plates 7, which are symmetrically fixed to the other end of the top of the operating table 1. Two sliding grooves 14 are formed through the outer walls of each support plate 7. The inner walls of the two support plates 7 are rotatably connected to the same first rotating shaft 18. A first conveying roller 8 is sleeved on the side wall of the first rotating shaft 18. Multiple first grooves 9 are evenly spaced on the outer wall of the first conveying roller 8. A motor 13 is fixed to the outer wall of one of the support plates 7, and the output shaft of the motor 13 is fixed to the first rotating shaft 18 via a coupling. The inner walls of the two sliding grooves 14 are slidably connected to the same second rotating shaft 17. A second conveying roller 10 is sleeved on the outer wall of the second rotating shaft 17. Multiple second grooves 11 are evenly spaced on the outer wall of the second conveying roller 10. 1 and multiple first grooves 9 correspond one-to-one. The outer walls of the two support plates 7 are provided with a second lifting mechanism for raising and lowering the second conveying roller 10. The second lifting mechanism includes a support plate 15, which is fixed to the outer wall of one of the support plates 7. A second hydraulic push rod 16 is fixed at the bottom of the support plate 15. The output shaft of the second hydraulic push rod 16 is rotatably connected to one end of the second rotating shaft 17. The two second hydraulic push rods 16 drive the second rotating shaft 17 to rise or fall along the inside of the two slide grooves 14, thereby driving the second conveying roller 10 to gradually move away from or closer to the first conveying roller 8. The drive motor 13 drives the first rotating shaft 18 to rotate, thereby driving the first conveying roller 8 to rotate. The rotation of the first conveying roller 8 cooperates with the second conveying roller 10 to convey the steel bars.

[0016] In this embodiment, the first lifting mechanism includes two first hydraulic push rods 6, which are symmetrically fixed at both ends of the top of the protective cover 2.

The bottom of the connecting plate 19 is fixed to a plurality of second connecting seats 12, and the top of the connecting plate 19 is fixed to the output ends of the two first hydraulic push rods 6. Driving the two first hydraulic push rods 6 in conjunction with the connecting plate 19 drives the plurality of second connecting seats 12 to rise or fall. By adjusting the distance between the second connecting seats 12 and the first connecting seats 21, steel bars of different thicknesses can be clamped.

[0017] In this embodiment, the dust removal mechanism includes a collection box 4, which is fixed to the middle of the top of the protective cover 2. A cover 5 is installed on the top of the collection box 4. A filter screen 27 is fixed to the inner wall of the collection box 4. An exhaust fan 23 is fixed to the top of the protective cover 2, and the air inlet of the exhaust fan 23 is connected to the collection box 4. The exhaust fan 23 is located below the filter screen 27. A sleeve 25 is fixed to the inner wall of the protective cover 2. Multiple branch pipes 26 are installed linearly at equal intervals on the outer wall of the sleeve 25, and all the branch pipes 26 are connected to the sleeve 25. A connecting pipe 24 is provided through the outer wall of the collection box 4. One end of the connecting pipe 24 is connected to the sleeve 25, and the other end of the connecting pipe 24 is located above the filter screen 27. The exhaust fan 23 is driven to evacuate the inside of the collection box 4, making the inside of the collection box 4 a negative pressure environment. Together with the connecting pipe 24, the inside of the sleeve 25 is also a negative pressure environment. The iron dust is sucked into the inside of the sleeve 25 through multiple branch pipes 26 and falls onto the top of the filter screen 27 through the connecting pipe 24 for collection. This allows for unified collection and treatment of the iron dust from the steel bars, preventing iron dust from splashing everywhere and affecting the health of workers, and improving the safety performance of the device.

[0018] Working principle: During use, the distance between the first conveying roller 8 and the second conveying roller 10 and the second connecting seat 12 and the first connecting seat 21 is adjusted according to the diameter of the steel bar. When adjusting the distance between the second connecting seat 12 and the first connecting seat 21, the power switches of the two first hydraulic push rods 6 are turned on at the same time. The two first hydraulic push rods 6, together with the connecting plate 19, drive the multiple second connecting seats 12 to rise or fall. At the same time, the power switches of the two second hydraulic push rods 16 are turned on at the same time. The two second hydraulic push rods 16 drive the second rotating shaft 17 to rise or fall along the inside of the two slide grooves 14, thereby driving the second conveying roller 10 to gradually move away from or closer to the first conveying roller 8. In this way, steel bars of different thicknesses can be straightened without replacing equipment, reducing the cost of use and improving the flexibility and practicality of the device. During correction, the reinforcing bar is inserted through the through hole 3 from one end of the protective cover 2. The reinforcing bar inside the protective cover 2 passes through one of the second connecting seats 12 and the first connecting seat 21, positioning it between the first arc-shaped groove 22 and the second arc-shaped groove 28. At this point, the reinforcing bar is tightly fitted with the second connecting seat 12 and the first connecting seat 21. The reinforcing bar is then inserted through the other end of the protective cover 2 until it is positioned between one of the first grooves 9 and the second groove 11. At this point, the reinforcing bar is tightly fitted with the first conveying roller 8 and the second conveying roller 10. The power switch of the motor 13 is then activated, driving the motor 13 to rotate the first rotating shaft 18, which in turn rotates the first conveying roller 8. The rotation of the first conveying roller 8, in conjunction with the second conveying roller 10, adjusts the reinforcing bar... During the conveying process, the steel bars can be straightened as they move. Due to the presence of the protective cover 2, the iron dust generated by the friction between the steel bars and the second connecting seat 12 and the first connecting seat 21 is confined inside the protective cover 2. While straightening, the power switch of the exhaust fan 23 is turned on, driving the exhaust fan 23 to evacuate the inside of the collection box 4, creating a negative pressure environment inside the collection box 4. This, combined with the connecting pipe 24, creates a negative pressure environment inside the sleeve 25. The iron dust is sucked into the sleeve 25 through multiple branch pipes 26 and then falls onto the top of the filter screen 27 through the connecting pipe 24 for collection. This allows for unified collection and treatment of the iron dust from the steel bars, preventing iron dust from splashing everywhere and affecting the health of workers, thus improving the safety performance of the device.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
