Description

Technical Field

[0001] This invention relates to the field of rebar straightening technology, specifically a multi-functional rebar straightening device for building construction. Background Technology

[0002] Civil engineering construction encompasses the construction of buildings, structures, and engineering works across various categories, including above-ground, underground, land, and water-based projects. This includes the construction of buildings, structures, and engineering works within facilities and sites such as houses, roads, railways, airports, bridges, water conservancy projects, ports, tunnels, water supply and drainage systems, and protective structures. It includes not only the technical activities of surveying, design, construction, maintenance, and management during the construction process, but also the materials, equipment, and supplies consumed during construction. For ease of transportation, steel bars with a diameter of less than 12 mm are generally made into coils (wire rods). These coiled steel bars must be straightened before cutting. Steel bars with a diameter greater than 12 mm are generally tied into... Straight steel bars, ranging from 6 to 12 meters in length, can experience localized bending during transport and handling. Therefore, to ensure construction quality, a steel bar straightening device is needed. Steel bar straightening also meets various requirements of civil engineering construction, ensuring higher quality steel bar installation. For example, bent or uneven steel bars cannot work effectively with concrete, leading to cracks and unnecessary damage. Furthermore, cutting unstraightened steel bars will result in inaccurate lengths, affecting the accuracy of steel bar forming, binding, and installation. Therefore, steel bar straightening is an indispensable step in civil engineering construction.

[0003] Currently, the straightening of coiled steel bars is mostly carried out on-site. Specifically, during the straightening process, the steel bars are bundled and placed on the ground, and pulled by a designated person. Steel bars not yet inside the straightening machine will swing irregularly and with large amplitude without restraint, which can affect surrounding workers and equipment, and potentially lead to safety accidents. To solve this problem, existing technologies usually place a protective cage at the inlet of the straightening machine. For example, Chinese patent CN201920918887.0 discloses a steel bar straightening protective device that uses several steel bar structures to restrain the swinging steel bars, thereby effectively eliminating safety hazards. However, it still has the following shortcomings:

[0004] When each coil of rebar is straightened to its end, the end of the rebar will swing freely as it is dragged forward. Especially during high-speed straightening, the swing amplitude is large. If it hits other equipment or objects, it will cause some damage. The current solution is to keep the straightening machine at a safe distance from other equipment, and there is no work area between the coiled rebar and the straightening machine. A protective cage is used to protect the swinging rebar. Therefore, the space occupied by one straightening machine is also relatively large. At present, construction sites usually only set up one or two straightening machines to process rebar. However, one straightening machine can only straighten one type of rebar at a time, which has limited processing efficiency and cannot meet the needs of large quantities of rebar. It also cannot straighten other urgently needed rebars of different diameters at the same time, which lacks functionality.

[0005] In view of this situation, the present invention provides a multifunctional rebar straightening device for building construction. The purpose is to enable the multifunctional straightening device for building construction to process rebars in multiple rebar trays at the same time by combining the dispersing anti-winding mechanism with the straightening structure, thereby improving processing efficiency. It can also straighten rebars of different diameters at the same time, and disperse the rebars in multiple rebar trays to prevent them from tangling together, while also reducing the swaying of the rebars during transmission. Summary of the Invention

[0006] To address the aforementioned problems, this application provides a multifunctional rebar straightening device for building construction, which solves the issues mentioned in the background art. Existing rebar straightening devices can only process rebar from one rebar tray at a time, resulting in limited processing efficiency. This fails to meet the demand for large quantities of rebar and also cannot simultaneously straighten other urgently needed rebars of different diameters, thus lacking functionality.

[0007] A multifunctional rebar straightening device for building construction includes a housing, a straightening structure, a conveying mechanism, and a separation and anti-winding mechanism. A base is fixedly connected to one side of the housing, and a mounting frame is provided on the top of the base. The straightening structure is located inside the housing. A frame is fixedly connected to one side of the housing, and a conveying mechanism is located inside the frame. A mounting plate is fixedly connected to one side of the frame by bolts. A hydraulic cutting mechanism for cutting rebar is provided on one side of the mounting plate. Multiple separation and anti-winding mechanisms are arranged in a conical pattern inside the mounting frame.

[0008] The separation anti-winding mechanism is assembled to disperse the steel bars of multiple steel bar coils when straightening multiple steel bar coils at the same time, preventing them from tangling together and reducing the swinging of the steel bars during transmission.

[0009] The guide block is designed to limit the swing of the reinforcing bar and can move the reinforcing bar by cooperating with the inclined block and the sliding plate to prevent the reinforcing bar from getting stuck during transmission.

[0010] The gear ring, powered by the motor, causes the inclined block to press against the sliding plate, thereby compressing the spring.

[0011] The straightening structure is assembled to simultaneously perform decentralized straightening processing on the reinforcing bars of multiple rebar discs.

[0012] Synchronous belt one is assembled to connect with multiple straightening structures, enabling the multiple straightening structures to operate simultaneously.

[0013] Furthermore, each of the aforementioned separation and anti-entanglement mechanisms includes a motor three and a base. The motor three is fixedly connected to the top of the base, and one end of the output shaft of the motor three is fixedly connected to a main rotating shaft. The base is fixedly connected to the inside of the mounting frame, and a secondary rotating shaft rotates inside the base. A synchronous belt three is provided on the outer wall of the secondary rotating shaft, and the secondary rotating shaft is driven by the main rotating shaft through the synchronous belt three. A spur gear is fixedly connected to the outer wall of the secondary rotating shaft, and a gear ring is rotatably connected inside the base. The spur gear and the gear ring mesh with each other, and several inclined blocks are fixedly connected to the outer wall of the gear ring.

[0014] Furthermore, each of the multiple bases has several protective shells fixedly connected inside. A spring seat is fixedly connected inside each protective shell. A spring is fixedly connected to one side of each spring seat. A lifting rod is fixedly connected to the other end of each spring. An arc plate is fixedly connected to one end of each lifting rod. A guide block is fixedly connected to one side of the arc plate. A sliding plate is fixedly connected to the outer wall of the lifting rod. The sliding plate is slidably connected inside the base. The inclined block can contact the sliding plate and can push the sliding plate.

[0015] Furthermore, a dispersing disc is fixedly connected to the top of the base, and the dispersing disc has several through holes inside.

[0016] Furthermore, a chassis is fixedly connected to one side of the housing, and a number of guide claws are fixedly connected to the outer wall of the chassis in a circular array. A number of guide cylinders are fixedly connected to one side of the housing, and the reinforcing bars enter the guide cylinders through the guide claws.

[0017] Furthermore, a motor is fixedly installed inside the casing, and a drive shaft is fixedly connected to one end of the output shaft of the motor. Several straightening structures are rotatably connected inside the casing. The outer wall of the rotating end of each of the straightening structures is provided with a synchronous belt. The straightening structures are all connected to the motor through the synchronous belt.

[0018] Furthermore, the conveying mechanism includes a second motor and a fixed plate. The fixed plate is fixedly connected to one side of the housing, and the second motor is fixedly connected to one side of the frame. One end of the output shaft of the second motor is fixedly connected to a drive shaft. A drive gear is fixedly connected to the outer wall of the drive shaft. A driven shaft and a driven gear shaft are rotatably connected inside the fixed plate. The drive gear is fixedly connected to the outer wall of the drive shaft. The drive gear meshes with the gear on the driven gear shaft. A second synchronous belt is provided on the outer wall of the driven gear shaft. The driven gear shaft is connected to the driven shaft via the second synchronous belt. A main rotating wheel and a secondary rotating wheel are slidably connected to the outer walls of the drive shaft and the driven shaft, respectively. The main rotating wheel can be fixed to the drive shaft, and the secondary rotating wheel can be fixed to the driven shaft. The interior of both the main rotating wheel and the secondary rotating wheel is provided with spherical grooves of different specifications. The reinforcing bar is in contact with the spherical grooves.

[0019] Furthermore, several hydraulic cutting mechanisms are fixedly installed on one side of the mounting plate.

[0020] Furthermore, both sides of the housing are hinged with doors.

[0021] The beneficial effects of this invention are as follows:

[0022] (1) The multi-functional steel bar straightening equipment for building construction described in this invention, through the cooperation of the dispersion anti-winding mechanism and the straightening structure, enables the multi-functional straightening equipment for building construction to process steel bars in multiple steel bar trays at the same time, thereby improving processing efficiency. It can also straighten steel bars of different diameters at the same time and disperse the steel bars in multiple steel bar trays, preventing them from winding together and reducing the swinging of steel bars during transmission.

[0023] In addition, the cooperation between the inclined block and the sliding plate allows the guide block to adjust the position of the reinforcing bar through intermittent contact, thereby avoiding the reinforcing bar getting stuck during transmission. Secondly, multiple separation and anti-winding mechanisms are distributed in a conical pattern to gradually disperse and limit each reinforcing bar, increasing the restriction on the reinforcing bar and reducing its swaying, thereby further improving construction safety.

[0024] (2) The multi-functional steel bar straightening equipment for building construction described in this invention can cut the steel bars by a hydraulic cutting mechanism after the steel bars are straightened and reach the preset length. In addition, the machine door can be opened to adjust or maintain the straightening structure. Furthermore, when straightening steel bars of different diameters, the positions of the main wheel and the auxiliary wheel on the outer walls of the drive shaft and the driven shaft can be adjusted to adapt to steel bars of different diameters and transport them, thereby improving the functionality of the multi-functional steel bar straightening equipment for building construction.

[0041] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the present invention will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is for the purpose of helping to understand the present invention, but does not constitute a limitation of the present invention.

[0042] Example:

[0043] like Figures 1-14 As shown, this embodiment of the invention provides a multi-functional rebar straightening device for building construction, including a housing 1, a straightening structure 3, a conveying mechanism 5, and a separation and anti-winding mechanism 9. A base 8 is fixedly connected to one side of the housing 1, and a mounting frame 81 is provided on the top of the base 8. The straightening structure 3 is provided inside the housing 1. A frame 4 is fixedly connected to one side of the housing 1. The conveying mechanism 5 is provided inside the frame 4. A mounting plate 6 is fixedly connected to one side of the frame 4 by bolts. A hydraulic cutting mechanism 7 for cutting rebar is provided on one side of the mounting plate 6. Multiple separation and anti-winding mechanisms 9 are provided inside the mounting frame 81, and the multiple separation and anti-winding mechanisms 9 are distributed in a conical shape.

[0044] The separation anti-winding mechanism 9 is assembled to disperse the steel bars of multiple steel bar discs when straightening multiple steel bar discs at the same time, so as to prevent them from winding together and reduce the swing of the steel bars during the transmission process.

[0045] The guide block 913 is configured to limit the swing of the reinforcing bar, and it can drive the reinforcing bar to move through the cooperation of the inclined block 907 and the sliding plate 908 to prevent the reinforcing bar from getting stuck during the transmission process.

[0046] The gear ring 906, through the power of the motor 901, can cause the inclined block 907 to apply pressure to the sliding plate 908, thereby compressing the spring 910;

[0047] The straightening structure 3 is assembled to simultaneously perform decentralized straightening processing on the reinforcing bars of multiple rebar discs.

[0048] Synchronous belt 31 is assembled to connect with multiple straightening structures 3 so that the multiple straightening structures 3 can operate simultaneously.

[0049] Each of the multiple separation and anti-entanglement mechanisms 9 includes a motor 901 and a base 905. The motor 901 is fixedly connected to the top of the base 8. One end of the output shaft of the motor 901 is fixedly connected to a main rotating shaft 902. The base 905 is fixedly connected to the inside of the mounting bracket 81. A secondary rotating shaft 903 rotates inside the base 905. A synchronous belt 915 is provided on the outer wall of the secondary rotating shaft 903. The secondary rotating shaft 903 is connected to the main rotating shaft 902 through the synchronous belt 915. A spur gear 904 is fixedly connected to the outer wall of the secondary rotating shaft 903. A gear ring 906 is rotatably connected inside the base 905. The spur gear 904 and the gear ring 906 mesh with each other. Several inclined blocks 907 are fixedly connected to the outer wall of the gear ring 906. Several protective shells 909 are fixedly connected inside the multiple bases 905. Springs are fixedly connected inside the protective shells 909. A spring seat 914 has a spring 910 fixedly connected to one side, and a lifting rod 911 fixedly connected to the other end of the spring 910. An arc plate 912 is fixedly connected to one end of the lifting rod 911, and a guide block 913 is fixedly connected to one side of the arc plate 912. A sliding plate 908 is fixedly connected to the outer wall of the lifting rod 911. The sliding plate 908 is slidably connected to the inside of the base 905. An inclined block 907 can contact the sliding plate 908 and can push the sliding plate 908. A dispersing disk 82 is fixedly connected to the top of the base 8. Several through holes are opened inside the dispersing disk 82. A housing 10 is fixedly connected to one side of the housing 1. Several guide claws 11 are fixedly connected to the outer wall of the housing 10 in a circular array. Several guide cylinders 12 are fixedly connected to one side of the housing 1. The reinforcing bar enters the guide cylinder 12 through the guide claws 11.

[0050] In this embodiment, each reinforcing bar is passed through the established straightening structure 3 for straightening. To prevent the reinforcing bars from tangling and swaying during dragging, they are sequentially passed through the dispersing disc 82, guide block 913, guide claw 11, and guide cylinder 12 into the straightening structure 3. After the reinforcing bars are limited, they may jam during transport, increasing the pressure on the conveying mechanism 5. At this time, the main shaft 902 can be driven to rotate by the motor 901, and the auxiliary shaft 903 can be rotated by the synchronous belt 915. Then, the meshing of the spur gear 904 and the gear ring 906 drives the gear ring 906 and the inclined block 907 to move. When the inclined block 907 contacts the sliding plate 908, it will continue to move. Pressure is applied to the sliding plate 908, causing it to continue sliding inside the base 905. The sliding plate 908 drives the lifting rod 911 to compress the spring 910. At the same time, the lifting rod 911 will drive the arc plate 912 and the guide block 913 to continue moving, which in turn will drive the steel bar inside the guide block 913 to move. The inner diameter of the guide block 913 is larger than that of the steel bar. Therefore, each time the inclined block 907 pushes the sliding plate 908 to move, the guide block 913 is equivalent to intermittently adjusting the position of the steel bar, thus avoiding the situation of the steel bar getting stuck during transmission. Secondly, the separation anti-winding mechanism 9 is distributed in a conical shape, thereby gradually dispersing and limiting each steel bar. The steel bar is directly fed into the straightening structure 3 for straightening through the guide claw 11.

[0051] In this embodiment, the straightening structure 3 and the separation anti-winding mechanism 9 can be set up according to actual processing requirements. The present invention is illustrated using five sets as an example.

[0052] A motor 32 is fixedly installed inside the casing 10. One end of the output shaft of the motor 32 is fixedly connected to a drive shaft 33. Several straightening structures 3 are rotatably connected inside the casing 1. The outer wall of the rotating end of each straightening structure 3 is provided with a synchronous belt 31. The straightening structures 3 are all connected to the motor 32 through the synchronous belt 31. The principle of the straightening structure 3 is that the motor 32 causes the drive shaft 33 to rotate, and then the synchronous belt 31 drives each straightening structure 3 to rotate. The steel bar is inside the straightening structure 3. The rotation of the straightening structure 3 is used to straighten the steel bar through the obliquely placed and rotating concave shaft. The straightening structure 3 is existing technology and will not be described in detail.

[0053] The conveying mechanism 5 includes a second motor 501 and a fixed plate 504. The fixed plate 504 is fixedly connected to one side of the housing 1, and the second motor 501 is fixedly connected to one side of the frame 4. One end of the output shaft of the second motor 501 is fixedly connected to a drive shaft 505. A drive gear 506 is fixedly connected to the outer wall of the drive shaft 505. A driven shaft 508 and a driven gear shaft 507 are rotatably connected inside the fixed plate 504. The drive gear 506 is fixedly connected to the outer wall of the drive shaft 505. The drive gear 506 and the driven gear shaft 507 are rotatably connected. The gears on 07 mesh with each other. The outer wall of the driven gear shaft 507 is provided with a timing belt 2 509. The driven gear shaft 507 is connected to the driven shaft 508 through the timing belt 2 509. The outer walls of the driving shaft 505 and the driven shaft 508 are respectively slidably connected with a main rotating wheel 502 and a secondary rotating wheel 503. The main rotating wheel 502 can be fixed to the driving shaft 505, and the secondary rotating wheel 503 can be fixed to the driven shaft 508. The interiors of the main rotating wheel 502 and the secondary rotating wheel 503 are provided with spherical grooves of different specifications, and the steel bars are in contact with the spherical grooves.

[0054] In this embodiment, motor 501 drives the drive shaft 505 to rotate. Then, the meshing of the drive gear 506 and the gear on the driven gear shaft 507 drives the driven gear shaft 507 to rotate. Then, the transmission of the synchronous belt 509 causes the driven shaft 508 to rotate, which in turn drives the main wheel 502 and the auxiliary wheel 503 to rotate in opposite directions. The steel bar comes into contact with the spherical grooves opened inside the main wheel 502 and the auxiliary wheel 503, so that the steel bar can be transported by the movement of the main wheel 502 and the auxiliary wheel 503. The main wheel 502 and the auxiliary wheel 503 can slide on the outer wall of the drive shaft 505 and the driven shaft 508 to accommodate steel bars of different diameters.

[0055] Several hydraulic cutting mechanisms 7 are fixedly installed on one side of the mounting plate 6. Machine doors 2 are hinged to both sides of the machine housing 1. After the steel bars are straightened and reach the preset length, the steel bars are cut by the hydraulic cutting mechanism 7. In addition, the machine door 2 can be opened to adjust or maintain the straightening structure 3.

[0056] Specific working methods:

[0057] In use, the steel bar tray is first hoisted to the designated position by a crane. When the steel bars of the steel bar tray are initially straightened, a special person pulls the steel bars and pulls them through the distribution plate 82, guide block 913, guide claw 11 and guide cylinder 12 into the straightening structure 3. After passing through the straightening structure 3, the steel bars pass through the conveying mechanism 5, and the main rotating wheel 502 and the auxiliary rotating wheel 503 provide subsequent movement for the steel bars.

[0058] The motor 501 drives the drive shaft 505 to rotate, and the meshing of the drive gear 506 with the gear on the driven gear shaft 507 drives the driven gear shaft 507 to rotate. Then, the synchronous belt 509 drives the driven shaft 508 to rotate, which in turn drives the main wheel 502 and the auxiliary wheel 503 to rotate in opposite directions. The steel bars come into contact with the spherical grooves opened inside the main wheel 502 and the auxiliary wheel 503, so that the steel bars can be transported by the movement of the main wheel 502 and the auxiliary wheel 503. The main wheel 502 and the auxiliary wheel 503 can slide on the outer wall of the drive shaft 505 and the driven shaft 508 to accommodate steel bars of different diameters.

[0059] Among them, the multi-functional steel bar straightening equipment for building construction can simultaneously process and straighten steel bars in multiple steel bar trays. Specifically, each steel bar is passed through the established straightening structure 3 and straightened separately. In order to prevent the steel bars from getting tangled and swinging when being dragged, the steel bars can be passed through the dispersion plate 82, guide block 913, guide claw 11 and guide cylinder 12 in sequence to enter the straightening structure 3.

[0060] Furthermore, after limiting the rebar, the rebar may jam during transmission, increasing the pressure on the conveying mechanism 5. In this case, the main shaft 902 can be driven to rotate by motor 3 901, and the auxiliary shaft 903 can be rotated via the synchronous belt 3 915. Then, the meshing of the spur gear 904 and gear ring 906 drives the gear ring 906 and the inclined block 907 to move. When the inclined block 907 contacts the sliding plate 908, its continued movement applies pressure to the sliding plate 908, thereby causing the sliding plate... 908 continues to slide inside the base 905. The sliding plate 908 drives the lifting rod 911 to compress the spring 910. At the same time, the lifting rod 911 will drive the arc plate 912 and the guide block 913 to continue to move, which will in turn drive the steel bar inside the guide block 913 to move. The inner diameter of the guide block 913 is larger than the steel bar. Therefore, each time the inclined block 907 pushes the sliding plate 908 to move, the guide block 913 is equivalent to intermittently adjusting the position of the steel bar, thereby avoiding the situation of the steel bar getting stuck during the transmission.

[0061] Secondly, the separation anti-winding mechanism 9 is distributed in a conical shape, thereby gradually dispersing and limiting each steel bar. The steel bar is directly fed into the straightening structure 3 for straightening through the guide claw 11. The straightening structure 3 and the separation anti-winding mechanism 9 can be set up according to the actual processing requirements. The present invention is illustrated with five groups as an example.

[0062] The principle of the straightening structure 3 is that the drive shaft 33 is rotated by the motor 32, and then the synchronous belt 31 drives each straightening structure 3 to rotate relative to each other. The steel bar is inside the straightening structure 3. The straightening structure 3 is used to straighten the steel bar by rotating through the concave rotating shaft that is placed obliquely and rotates. The straightening structure 3 is existing technology and will not be described in detail here.

[0063] Finally, after the steel bars are straightened and reach the preset length, the steel bars are cut by the hydraulic cutting mechanism 7. In addition, the machine door 2 can be opened to adjust or maintain the straightening structure 3.

[0064] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
