Description
Technical Field
[0001] This utility model relates to the field of steel bar bending technology in building construction, and in particular to a steel bar bending device for building construction. Background Technology
[0002] In the field of building construction, steel bars are a key building material, and their processing quality is directly related to the stability of the engineering structure. Steel bar bending operations are extremely common, requiring steel bars to be bent into specific shapes to meet the needs of different building structures.
[0003] During the bending process of steel bars, due to the bending force, the steel bars are prone to suddenly bounce up or shift, which may cause serious safety accidents such as crushing and scratching to the operators and threaten the lives of construction workers. In order to solve the above problems, we propose a steel bar bending device for building construction. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a steel bar bending device for building construction.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A steel bar bending device for building construction includes a support plate, a turntable rotatably mounted on the upper side of the support plate, and a bending protection component on the turntable. The bending protection component includes a fixed cylinder, which is fixedly mounted on the upper side of the turntable. The fixed cylinder has symmetrical grooves on both sides, and a protective stop block is slidably mounted inside the groove. A compression spring is fixedly connected to the rear side of the protective stop block, and an inner pull rope is fixedly connected to the inner side of the protective stop block. A pull rope is connected to the lower end of the inner pull rope and passes through to the outside of the fixed cylinder. A first column and a second column are fixedly mounted on the upper side of the support plate, and the outer end of the pull rope is fixedly connected to the second column.
[0007] Furthermore, a support leg is fixedly installed at the bottom of the support plate.
[0008] By adopting the above technical solution, the outriggers provide bottom support for the support plate.
[0009] Furthermore, a controller is fixedly installed on the front side of the support plate.
[0010] Furthermore, a first fixed column and a second fixed column are fixedly installed on the upper side of the support plate, and a rotating sleeve is rotatably installed on the outer side of the second fixed column.
[0011] By adopting the above technical solution, the rotating sleeve will adapt to the bending of the steel bar when it is bent, thus avoiding lateral friction and scratching of the steel bar.
[0012] Furthermore, structural steel bars are placed on the upper side of the support plate.
[0013] Furthermore, a rotating shaft is rotatably mounted on the lower side of the support plate. The rotating shaft rotates through to the upper side of the support plate and is fixedly connected to the bottom of the turntable. A large gear is fixedly mounted on the bottom of the rotating shaft.
[0014] By adopting the above technical solution, when the large gear rotates, it can drive the upper turntable to rotate through the rotating shaft, and the turntable will drive the fixed cylinder to rotate, so as to bend the building steel bars.
[0015] Furthermore, a servo motor is fixedly installed at the bottom of the support plate, and a small gear is fixedly installed on the output end of the servo motor, which meshes with a large gear.
[0016] Furthermore, a protective cover is fixedly installed at the bottom of the support plate, and the protective cover has heat dissipation holes. The protective cover covers the outside of the large gear, servo motor and small gear.
[0017] By adopting the above technical solution, the starter servo motor can drive the pinion to rotate, and the pinion meshes with the large gear to provide driving force for the turntable on the upper side of the support plate.
[0018] Furthermore, a fixing block is fixedly installed on the top inner side of the fixing cylinder, and the fixing block is fixedly connected to the inner end of the compression spring. A rotating column is rotatably installed on the inner wall of the fixing cylinder, and the inner pull rope rotates around the rotating column.
[0019] Furthermore, a rotating wheel is rotatably installed on the outer side of the first column, the pull rope rotates around the rotating wheel, a protective cylinder is fixedly installed on the side wall of the fixed cylinder, and the pull rope slides through the protective cylinder.
[0020] By adopting the above technical solution, the rotating column provides guidance for the inner pull rope, and the protective cylinder and rotating wheel provide guidance for the pull rope.
[0021] Compared with related technologies, the steel bar bending device for building construction proposed in this utility model has the following beneficial effects:
[0022] In this utility model, a steel bar bending device for building construction is provided. Through a bending protection component, under the rebound force of a compression spring, a protective stop block is pushed to move outwards from the groove, causing it to protrude beyond the groove. This prevents the steel bar from bulging upwards and folding while bending, improving safety. As the turntable rotates, it gradually moves the fixing cylinder away from the second column, causing the inner pull rope to retract the protective stop block into the groove. When the bending is complete, the protective stop block is fully retracted into the groove, facilitating the upward sliding and extraction of the bent steel bar, thus enhancing practicality.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0030] Reference Figures 1-5 A steel bar bending device for building construction includes a support plate 1, a turntable 15 rotatably mounted on the upper side of the support plate 1, and a bending protection component 7 provided on the turntable 15. The bending protection component 7 includes a fixed cylinder 71, which is fixedly mounted on the upper side of the turntable 15. The fixed cylinder 71 has symmetrically opened grooves 72 on both sides. A protective stop block 73 is slidably mounted inside the groove 72. A compression spring 710 is fixedly connected to the rear side of the protective stop block 73. An inner pull rope 711 is fixedly connected to the inner side of the protective stop block 73. A pull rope 75 is connected to the lower end of the inner pull rope 711 and passes through to the outside of the fixed cylinder 71. A first column 76 and a second column 78 are fixedly mounted on the upper side of the support plate 1. The outer end of the pull rope 75 is fixedly connected to the second column 78.
[0031] In this embodiment, a first fixed column 4 and a second fixed column 5 are fixedly installed on the upper side of the support plate 1, a rotating sleeve 6 is rotatably installed on the outer side of the second fixed column 5, and a building steel bar 8 is placed on the upper side of the support plate 1.
[0032] With the above structure, the rotating sleeve 6 will rotate adaptively with the bending of the reinforcing steel bar 8 when bending it, thus avoiding lateral friction and scratching of the reinforcing steel bar.
[0033] In this embodiment, a rotating shaft 11 is rotatably mounted on the lower side of the support plate 1. The rotating shaft 11 rotates through to the upper side of the support plate 1 and is fixedly connected to the bottom of the turntable 15. A large gear 12 is fixedly mounted on the bottom of the rotating shaft 11. A servo motor 13 is fixedly mounted on the bottom of the support plate 1. A small gear 14 is fixedly mounted on the output end of the servo motor 13. The small gear 14 meshes with the large gear 12.
[0034] With the above structure, when the servo motor 13 starts, it can drive the pinion 14 to rotate. The pinion 14 meshes with the large gear 12, and then uses the rotating shaft 11 to drive the turntable 15 to rotate, so as to provide bending power for the building steel bars 8.
[0035] In this embodiment, a protective cover 9 is fixedly installed at the bottom of the support plate 1. The protective cover 9 has heat dissipation holes 10 and covers the outside of the large gear 12, the servo motor 13 and the small gear 14.
[0036] Through the above structure, the protective cover 9 is used to provide meshing protection for the pinion 14 and the gear 12.
[0037] In this embodiment, a fixing block 79 is fixedly installed on the top inner side of the fixing cylinder 71. The fixing block 79 is fixedly connected to the inner end of the compression spring 710. A rotating column 712 is rotatably installed on the inner wall of the fixing cylinder 71. The inner pull rope 711 rotates and passes around the rotating column 712. A rotating wheel 77 is rotatably installed on the outer side of the first column 76. The pull rope 75 rotates and passes around the rotating wheel 77. A protective cylinder 74 is fixedly installed on the side wall of the fixing cylinder 71. The pull rope 75 slides through the protective cylinder 74.
[0038] Through the above structure, the rotating column 712 provides guidance for the inner pull rope 711, and the protective cylinder 74 and the rotating wheel 77 provide guidance for the pull rope 75.
[0039] In this embodiment, a support leg 2 is fixedly installed at the bottom of the support plate 1, and a controller 3 is fixedly installed at the front of the support plate 1.
[0040] With the above structure, the controller 3 is used to control the working state of the servo motor 13.
[0041] In this invention, before the bending operation begins, the compression spring 710 in the bending protection assembly 7 is in a naturally extended state. Under its rebound force, it pushes the protective stop 73 to move outward from the slide groove 72, causing the protective stop 73 to protrude outward from the slide groove 72 and be positioned above the reinforcing steel bar 8, ready to provide protection during the bending process. As the turntable 15 rotates, the fixing cylinder 71, which is fixedly installed on the upper side of the turntable 15, also rotates. The fixing cylinder 71 gradually approaches the reinforcing steel bar 8 and applies pressure to the steel bar, causing it to bend. During the bending process, the rotating sleeve 6 adapts to the bending of the steel bar, avoiding lateral friction and scratches. At the same time, the protective stop 73 effectively prevents the steel bar from protruding upward. The folding mechanism reduces the risk of accidental deformation or injury caused by uneven stress during the bending process of the reinforcing bar, thus improving operational safety. As the turntable 15 continues to rotate, the fixed cylinder 71 gradually moves away from the second column 78. At this time, the pull rope 75, which is fixedly connected to the second column 78, is gradually tightened. The pull rope 75 drives the inner pull rope 711 to move. The inner pull rope 711 passes around the rotating column 712 (the rotating column 712 provides guidance for the inner pull rope 711) and pulls the protective stop block 73 to overcome the elastic force of the compression spring 710 and move it to the inside of the slide groove 72. When the reinforcing bar is bent, the protective stop block 73 is completely retracted into the inside of the slide groove 72. The operator slides the bent reinforcing bar upward from the support plate 1 and pulls it out, completing one reinforcing bar bending operation.
