Description

Technical Field

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

[0002] Steel bars are a commonly used metal material in construction engineering, mainly used to enhance the strength and toughness of concrete. Steel bars often bend during transportation, storage and early processing. Therefore, in order to ensure that steel bars meet the requirements of construction use, it is necessary to straighten the bent steel bars before use.

[0003] According to the Chinese patent "A Rebar Straightening Device" authorized announcement number "CN217798655U", after the rebar passes through the first through hole of the first straightening plate, it passes through the grooves on the two straightening rollers, so that the two straightening rollers straighten the rebar. The first straightening plate can move back and forth, and can pre-straighten the rebar. When the first straightening plate moves backward, it can reduce the bending arc of the rebar and limit the rebar to prevent the tail end of the rebar from swinging violently.

[0004] Although the above application can straighten the reinforcing bars, during the straightening process in the groove of the straightening roller, iron filings and dust generated on the surface of the reinforcing bars will remain in the groove. When the rust and dust in the groove gradually increase, it will affect the straightening effect of the reinforcing bars.

[0005] Therefore, a steel bar straightening device for civil engineering construction is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a steel bar straightening device for civil engineering construction in order to solve the above-mentioned problems. It improves the problem that iron filings and dust generated on the surface of the steel bar during the straightening process will remain in the groove, thereby affecting the straightening effect of the steel bar.

[0007] This utility model achieves the above-mentioned objective through the following technical solution: a steel bar straightening device for civil engineering construction, comprising: an operating table, a fixed frame and a driving mechanism installed on the top of the operating table, two straightening rollers rotatably connected to the inner wall of the fixed frame; two cleaning mechanisms, each cleaning mechanism including two meshing first gears; two fixed plates fixedly connected to one side of the fixed frame, and a circular roller rotatably connected between the opposite sides of the two fixed plates; one end of one straightening roller and one end of the circular roller are respectively fixedly connected to one end of the two first gears; a plurality of first cleaning brushes are fixedly connected to the surface of the circular roller; and a plurality of second cleaning brushes are slidably connected to the surface of the circular roller, the first cleaning brushes and the second cleaning brushes being staggered.

[0008] Preferably, the cleaning mechanism further includes a protrusion fixedly connected to one side of one of the fixed plates, a ball fixedly connected to one end of the second cleaning brush, a limiting block fixedly connected to the surface of the second cleaning brush, and a spring fixedly connected between one side of the limiting block and the inner wall of the roller. This facilitates the brush bristles of the second cleaning brush to rub against the groove of the straightening roller during cleaning, thereby enhancing the cleaning effect on the groove of the straightening roller.

[0009] Preferably, a cleaning frame is fixedly connected between the opposite sides of the two fixed plates. The interior of the cleaning frame is filled with an aqueous solution. An installation rod is slidably connected to the inner wall of the cleaning frame, and multiple sets of levers are fixedly connected to one side of the installation rod. This facilitates the deformation of the bristles of the first and second cleaning brushes after they enter the cleaning frame, causing impurities and iron filings on the bristles to fall into the aqueous solution inside the cleaning frame. This helps reduce the impurity content on the brush bristles in the air and improves the cleaning effect of the first and second cleaning brushes.

[0010] Preferably, a first motor is fixedly connected to one side of the cleaning frame, and a reciprocating lead screw is fixedly connected to the output shaft of the first motor. A moving block is provided on the surface of the reciprocating lead screw, and one side of the moving block passes through the cleaning frame and is fixedly connected to the other side of the mounting rod. This facilitates driving the moving block to move the mounting rod and multiple sets of levers back and forth, enhancing the cleaning effect of the levers on the brush bristles.

[0011] Preferably, the overall shape of the protrusion is half-sphere, and the diameter of the protrusion is larger than the diameter of the sphere. This facilitates better compression of the sphere by the protrusion.

[0012] Preferably, the vertical cross-section of the lever is an isosceles triangle. This facilitates better scraping of impurities from the brush bristles while preventing impurities from remaining on the lever.

[0013] Preferably, the surface of the roller has a groove that matches the limiting block, and the surface of the limiting block is slidably connected to the inner wall of the groove. This facilitates limiting the movement of the second cleaning brush and ensures the stability of the device during operation.

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

[0015] 1. In the above-mentioned cleaning mechanism, under the action of the two first gears, the round roller drives the first cleaning brush and the second cleaning brush to rotate in opposite directions to the straightening roller to clean the impurities and iron filings in the groove of the straightening roller. This avoids the accumulation of impurities and rust in the groove of the straightening roller when it straightens the steel bars, ensuring that the groove of the straightening roller is always clean. At the same time, it also helps the first cleaning brush and the second cleaning brush to push the iron filings and impurities in the groove of the straightening roller to the outside of the straightening roller during cleaning, preventing the cleaned impurities from re-entering the groove. When the second cleaning brush cleans the groove of the straightening roller, under the action of the protrusion, the ball and the spring, it helps the bristles of the second cleaning brush to rub against the groove of the straightening roller during cleaning, which enhances the cleaning effect on the groove of the straightening roller and ensures the straightening effect of the straightening roller on the steel bars.

[0016] 2. During the rotation of the first and second cleaning brushes, the action of multiple sets of levers helps the bristles of the first and second cleaning brushes to deform after entering the cleaning frame, thereby causing impurities and iron filings on the bristles to fall into the aqueous solution inside the cleaning frame. This helps reduce the impurity content on the brush bristles in the air and improves the cleaning effect of the first and second cleaning brushes. Attached Figure Description

[0023] 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.

[0024] In practical implementation: such as Figure 1-5 As shown, a steel bar straightening device for civil engineering construction includes: an operating platform 1, with a fixed frame 2 and a driving mechanism 3 installed at the top of the operating platform 1; two straightening rollers 4 rotatably connected to the inner wall of the fixed frame 2; two cleaning mechanisms 5, each including two meshing first gears 51; two fixed plates 52 fixedly connected to one side of the fixed frame 2; and a circular roller 53 rotatably connected between the opposite sides of the two fixed plates 52. One end of one straightening roller 4 and one end of the circular roller 53 are respectively fixedly connected to one end of the two first gears 51; multiple first cleaning brushes 54 are fixedly connected to the surface of the circular roller 53; and multiple second cleaning brushes 55 are slidably connected to the surface of the circular roller 53. The first cleaning brushes 54 and the second cleaning brushes 55 are staggered.

[0025] In this embodiment, multiple cylinders are installed on the other side of the fixing frame 2. The openings of the cylinders are funnel-shaped, and the positions of the cylinders correspond one-to-one with the positions of the grooves on the surface of the straightening roller 4. The cylinders guide the steel bars when they are placed in.

[0026] The drive mechanism 3 includes a second motor fixedly connected to the top of the operating table 1. The other ends of the two straightening rollers 4 extend through the fixed frame 2 and are fixedly connected to second gears. The two second gears mesh with each other, and the other end of one of the second gears is fixedly connected to the output shaft of the second motor. Therefore, when the second motor is started by the controller, the output shaft of the second motor will drive the two second gears to rotate in opposite directions, thereby driving the two straightening rollers 4 to rotate in opposite directions to straighten the reinforcing bars. When the straightening rollers 4 rotate, under the action of the two first gears 51, they will drive the circular roller 53 to rotate synchronously, and the rotation direction of the circular roller 53 is opposite to the rotation direction of the straightening rollers 4.

[0027] Multiple first cleaning brushes 54 and multiple second cleaning brushes 55 are arranged in a ring. The positions of the bristles installed on the first cleaning brushes 54 and the bristles installed on the second cleaning brushes 55 correspond one-to-one with the grooves on the surface of the straightening roller 4. When the circular roller 53 drives the first cleaning brushes 54 and the second cleaning brushes 55 to rotate, the bristles of the first cleaning brushes 54 and the bristles of the second cleaning brushes 55 will enter the grooves.

[0028] like Figure 3 and Figure 4As shown, the cleaning mechanism 5 also includes a protrusion 56 fixedly connected to one side of one of the fixed plates 52, a ball 57 fixedly connected to one end of the second cleaning brush 55, a limiting block 58 fixedly connected to the surface of the second cleaning brush 55, and a spring 59 fixedly connected between one side of the limiting block 58 and the inner wall of the roller 53. The overall shape of the protrusion 56 is half-sphere, and the diameter of the protrusion 56 is larger than the diameter of the ball 57.

[0029] In this embodiment, as the roller 53 drives multiple second cleaning brushes 55 to rotate, the rotation path of the ball 57 will coincide with the protrusion 56. When the bristles of the second cleaning brush 55 enter the groove of the straightening roller 4 during rotation and gradually rotate to a horizontal state, the ball 57 corresponding to the second cleaning brush 55 will contact the surface of the protrusion 56. Under the pressure of the protrusion 56, the second cleaning brush 55 will move horizontally. The limiting block 58 moves synchronously and squeezes the spring 59. When the second cleaning brush 55 continues to rotate and gradually releases contact with the protrusion 56, the spring 59 will drive the second cleaning brush 55 to automatically reset.

[0030] like Figure 2 and Figure 5 As shown, a cleaning frame 510 is fixedly connected between the opposite sides of the two fixed plates 52. The interior of the cleaning frame 510 is filled with an aqueous solution. An installation rod 511 is slidably connected to the inner wall of the cleaning frame 510. Multiple sets of levers 512 are fixedly connected to one side of the installation rod 511. The vertical cross-section of the lever 512 is an isosceles triangle.

[0031] In this embodiment, the position of each set of levers 512 corresponds to the position of the bristles on the first cleaning brush 54 and the second cleaning brush 55. During the rotation of the first cleaning brush 54 and the second cleaning brush 55, the bristles will enter the cleaning frame 510 and contact the levers 512, and the bristles will deform under the action of the levers 512.

[0032] When the first cleaning brush 54 and the second cleaning brush 55 enter the cleaning frame 510, the height of their bristles is higher than the horizontal height of the aqueous solution inside the cleaning frame 510.

[0033] The bottom of the cleaning frame 510 is inclined, and a through groove is provided on one side of the lower end of the cleaning frame 510. A sealing plate matching the through groove is provided. When the device is running, the sealing plate seals the through groove. When it is necessary to clean the inside of the cleaning frame 510, the sealing plate can be opened.

[0034] like Figure 5As shown, a first motor 513 is fixedly connected to one side of the cleaning frame 510, and a reciprocating screw 514 is fixedly connected to the output shaft of the first motor 513. A moving block 515 is provided on the surface of the reciprocating screw 514, and one side of the moving block 515 passes through the cleaning frame 510 and is fixedly connected to the other side of the mounting rod 511.

[0035] In this embodiment, the surface of the moving block 515 is slidably connected to the inner wall of the cleaning frame 510. The reciprocating screw 514 is in the form of two threaded grooves with the same pitch and opposite directions, connected at both ends by a transition curve. By rotating the reciprocating screw 514, the side of the spiral groove pushes the slider placed in the spiral groove to make axial reciprocating motion. Therefore, when the reciprocating screw 514 rotates, it will drive the mounting rod 511 to reciprocate through the moving block 515.

[0036] like Figure 4 As shown, the surface of the roller 53 is provided with a groove 516 that matches the limiting block 58, and the surface of the limiting block 58 is slidably connected to the inner wall of the groove 516.

[0037] In this embodiment, the spring 59 is disposed on the inner side of the slide groove 516, and the slide groove 516 limits the movement of the second cleaning brush 55.

[0038] In use, the reinforcing bar is inserted into the groove of the straightening roller 4, and the two straightening rollers 4 are rotated in opposite directions by the drive mechanism 3 to straighten the reinforcing bar. Simultaneously, the straightening rollers 4 drive two sets of cleaning mechanisms 5 to operate synchronously. During the operation of the cleaning mechanisms 5, under the action of the two first gears 51, the rotation of the straightening rollers 4 drives the circular rollers 53 to rotate in opposite directions. This causes the circular rollers 53 to drive the first cleaning brush 54 and the second cleaning brush 55 to rotate synchronously. During rotation, the bristles of the first cleaning brush 54 and the second cleaning brush 55 enter the groove of the straightening roller 4 to clean the iron filings and impurities within the groove. Simultaneously, as the second cleaning brush 55 rotates, its bristles enter the groove of the straightening roller 4 and gradually rotate to a horizontal position... Under the action of the protrusion 56, the ball 57 and the spring 59, the second cleaning brush 55 will move back and forth in a small horizontal amplitude, so that the bristles of the second cleaning brush 55 will rub in the groove of the straightening roller 4. During the rotation of the first cleaning brush 54 and the second cleaning brush 55, the bristles will enter the cleaning frame 510. At this time, the bristles will be deformed under the action of the lever 512. At the same time, the controller starts the first motor 513 to drive the reciprocating screw 514 to rotate, so that the moving block 515 drives the mounting rod 511 and multiple sets of levers 512 to move back and forth. At this time, the impurities and iron filings on the bristles will fall into the aqueous solution in the cleaning frame 510 under the action of the lever 512, thereby reducing the impurity content on the brush bristles in the air.

[0039] It should be noted that the first motor 513 and other components mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the first motor 513 can be powered by the built-in power supply or by the mains power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0040] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
