Description

Technical Field

[0001] The invention relates to the technical field of construction, and in particular to a construction steel bar correction device with a safety protection function. Background Art

[0002] During cast-in-place pile construction, the pile head elevation is higher than the design elevation, and this part needs to be removed manually to ensure the strength of the pile body. After the pile head is crushed, the steel bars in the pile head are often exposed, but the damage caused by the crusher causes the steel bars to bend and deform, making it impossible to proceed to the next step of work, so the exposed steel bars need to be corrected.

[0003] The existing steel bar straightening method usually uses a steel pipe to penetrate the steel bar, and then relies on manpower to push the steel pipe to straighten the steel bar. The manual straightening speed is slow and the efficiency is low. In addition, it is easy to cause safety accidents such as steel bar rebound and injury.

[0004] In addition, there is also a method of using hydraulic pliers to straighten steel bars in the prior art. Since there is often more than one bend on each steel bar, the hydraulic pliers need to be moved multiple times on each steel bar for correction, which makes the construction slow and cumbersome. In addition, the hydraulic pliers can only correct small-range bends in the steel bar, and manual straightening is still required for the tilt problem of the entire steel bar.

[0005] To this end, we proposed a building steel bar correction device with safety protection function. Summary of the invention

[0018] 1.

After the lifting unit drives the sleeve and the clamping unit to rise, all local bent parts on the steel bar can be corrected. Compared with the hydraulic pliers in the prior art, which need to move on the steel bar until all bent parts are corrected, the correction efficiency of the present invention is higher.

[0020] 3. The present invention drives the correction component to rotate around the column through the cooperation between the set rotating component, the annular slide rail and the correction component, and can correct the steel bars on the column one by one. There is no need for workers to touch the steel bars, which improves safety. When in use, the outer ring seat is fixed to the outside of the column, and the mounting plate is placed at the center of the top of the column, so that the column, the annular slide rail, the slewing support internal gear and the mounting plate are coaxial. When the starting motor drives the active gear to rotate, it drives the slewing support internal gear to rotate, and then drives the correction component to rotate around the column on the annular slide rail, so that the correction component is rotated one by one to just above the steel bars. Compared with the prior art, which manually corrects the steel bars one by one by holding the tool around the outside of the column, the work efficiency is improved; at the same time, the sleeve can correspond to the steel bars at the top of the column one by one, so that the sleeve, the annular plate and the steel bars are coaxial, which improves the correction accuracy.

[0021] 4. When the present invention is used, there is no need for manual contact with the steel bars, thereby improving safety. In addition, the annular protective enclosure prevents the correction components from injuring nearby workers, thereby further improving safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] like Figure 1-Figure 11As shown, the present invention is a building steel bar correction device with a safety protection function, comprising a column 1, an outer ring seat 2, a mounting plate 3, a rotating assembly 4 and a correction assembly 5. The column 1 is a cylindrical structure, and a plurality of steel bars 6 are arranged at the upper edge of the column 1. The outer ring seat 2 is an annular structure and is sleeved on the outside of the column 1. The mounting plate 3 is a circular structure and is located at the center of the outer ring seat 2.

The rotating assembly 4 is arranged on the mounting plate 3, and an annular slide rail 7 is fixedly arranged on the top of the outer ring seat 2. The correction assembly 5 is arranged and connected to the rotating assembly 4 and the annular slide rail 7 respectively.

[0038] like Figure 1-Figure 11 As shown, the rotating component 4 includes a fixed bracket 41, a motor 42, a driving gear 43 and a slewing support internal gear 44, the slewing support internal gear 44 is fixedly arranged on the top of the mounting plate 3, the fixed bracket 41 is fixedly arranged on the top of the mounting plate 3 and is located on the inner side of the slewing support internal gear 44, the motor 42 is fixedly arranged on the top of the fixed bracket 41, the driving gear 43 is fixedly arranged on the output shaft of the motor 42, the driving gear 43 is meshed with the slewing support internal gear 44, and the bottom of the correction component 5 is fixedly connected to the top of the slewing support internal gear 44.

[0039] By cooperating between the rotating component 4, the annular slide rail 7 and the correction component 5, the correction component 5 is driven to rotate around the column 1, so that the steel bars 6 on the column 1 can be corrected one by one, and the staff does not need to touch the steel bars 6, which improves the safety. When in use, the starting motor 42 drives the active gear 43 to rotate, and then drives the slewing support internal gear 44 to rotate, and then drives the correction component 5 to rotate around the column 1 on the annular slide rail 7, so that the correction component 5 is rotated to the top of the steel bars 6.

[0040] like Figure 1-Figure 11 As shown, the correction assembly 5 includes an annular plate 51 and a sleeve 53. Three groups of lifting units 52 are evenly distributed on the annular plate 51. The sleeve 53 is located below the annular plate 51. The lifting units 52 are evenly distributed around the sleeve 53. A connecting rod mechanism 54 is provided between the sleeve 53 and each group of lifting units 52. Each group of connecting rod mechanisms 54 is provided with a clamping unit 55. The clamping unit 55 extends into the sleeve 53.

[0041] like Figure 1-Figure 11As shown, the lifting unit 52 includes a fixed plate 521, a screw rod 1 522, a vertical rod 523, a motor 2 524 and a lifting plate 525. The motor 2 524 is fixedly arranged on the top of the annular plate 51. The top end of the screw rod 1 522 rotates through the annular plate 51 and is fixedly connected to the output end of the motor 2 524. The fixed plate 521 is rotatably connected to the bottom end of the screw rod 1 522 through a bearing. The top end of the vertical rod 523 is fixedly connected to the bottom of the annular plate 51 and is symmetrically located on both sides of the screw rod 1 522. The bottom end of the vertical rod 523 is fixedly connected to the top of the fixed plate 521. The lifting plate 525 The lifting plate 525 is slidably sleeved on the vertical rod 523, and the middle part of the lifting plate 525 is threadedly connected with the screw rod 1 522. The fixed plate 521 on one set of lifting units 52 is fixedly connected to the top of the slewing support internal gear 44, and the fixed plates 521 on the other two sets of lifting units 52 are fixedly connected to the top of the slider on the annular slide rail 7. The fixed plate 521 and the slewing support internal gear 44 and the annular slide rail 7 are all detachably fixed, so that the lifting unit 52 can be completely removed from the slewing support internal gear 44 and the annular slide rail 7, and then installed and connected when needed.

[0042] like Figure 1-Figure 11 As shown, the connecting rod mechanism 54 includes two groups of parallel movable rods 541, a connecting block 1 542 and a connecting block 2 543. The connecting block 1 542 is fixedly arranged on the side wall of the lifting plate 525 facing the central axis of the sleeve 53, and the connecting block 2 543 is fixedly arranged on the side wall of the sleeve 53. A pin 1 544 is rotatably sleeved on the connecting block 1 542, and a pin 2 545 is rotatably sleeved on the connecting block 2 543. The two ends of the movable rod 541 are hinged to one end of the pin 1 544 and one end of the pin 2 545 respectively.

[0043] The three groups of lifting units 52 are fixed together by the set annular plate 51. The set lifting unit 52 cooperates with the connecting rod mechanism 54 to drive the sleeve 53 to rise and fall, and at the same time, it can also drive the sleeve 53 to move in various directions on the horizontal plane. When the steel bar 6 enters the sleeve 53, the movement of the sleeve 53 is used to straighten the inclined steel bar 6. When in use, the control motor 2 524 is controlled to perform forward or reverse rotation, so that the movable rod 541 on the corresponding lifting unit 52 can swing with the lifting of each lifting plate 525, thereby driving the sleeve 53 to swing, and then the inclined steel bar 6 can be straightened.

[0044] like Figure 1-Figure 11As shown, the clamping unit 55 includes a motor three 551, a screw rod two 552, a threaded barrel 553, a U-shaped plate 554 and an extrusion wheel 555. The motor three 551 is fixedly arranged on the top of the connecting block two 543, the screw rod two 552 is fixedly arranged on the output end of the motor three 551, the threaded barrel 553 is threadedly sleeved on the screw rod two 552, the threaded barrel 553 slides through the inner wall of the sleeve 53, the U-shaped plate 554 is fixedly arranged on one end of the threaded barrel 553 located in the sleeve 53, the extrusion wheel 555 is rotatably arranged on the inner side of the U-shaped plate 554 through a rotating shaft, and the extrusion wheel 555 is linearly distributed in a plurality of groups along the vertical direction in the same group of U-shaped plates 554 (one group is shown in the accompanying drawings), and the clamping unit 55 also includes a guide rod 556, one end of the guide rod 556 is fixedly arranged on the side wall of the U-shaped plate 554, and is symmetrically located on the left and right sides of the threaded barrel 553, and the other end of the guide rod 556 slides through the inner wall of the sleeve 53.

[0045] By cooperating with the clamping unit 55 and the lifting unit 52, the bent portion on the steel bar 6 can be corrected and straightened. When in use, the three motors 551 are started to drive the screw rod 552 to rotate, thereby driving the threaded cylinder 553 to move toward the center of the sleeve 53, so that the three extrusion wheels 555 are tightly fitted to the surface of the steel bar 6, and then the three motors 524 are started at the same time to make the sleeve 53 rise, thereby driving the extrusion wheels 555 to rise in the vertical direction. At this time, under the extrusion of multiple extrusion wheels 555, the bent portion on the steel bar 6 is corrected until the sleeve 53 is separated from the steel bar 6, thereby completing the correction operation of the column head steel bar 6.

[0046] like Figure 1-Figure 11 As shown, multiple sets of locking bolts 8 are threadedly connected to the outer ring seat 2, and the locking bolts 8 are in close contact with the side wall of the column 1. The outer ring seat 2 can be fixed on the column 1 through the provided locking bolts 8.

[0047] like Figure 1-Figure 11 As shown, an annular protective enclosure plate 9 is clamped on the top of the outer ring seat 2, and a clamping plate 10 is distributed on the circumferential side wall of the outer ring seat 2. A clamping gap is left between the clamping plate 10 and the side wall of the outer ring seat 2, and the bottom of the annular protective enclosure plate 9 is inserted into the clamping gap. The cooperation between the annular protective enclosure plate 9 and the clamping gap facilitates the disassembly and assembly of the annular protective enclosure plate 9.

[0048] like Figure 1-Figure 11 As shown, a hanging rod 11 is fixedly provided in the middle of the installation plate 3, and a hanging ring 12 is provided at the top of the hanging rod 11. The installation plate 3 can be easily carried by the setting of the hanging rod 11.

[0049] like Figure 1-Figure 11As shown, the column 1, the annular slide rail 7, the slewing support internal gear 44 and the mounting plate 3 are coaxial. The four coaxial lines can enable the correction assembly 5 to rotate around the circumference of the column 1, so that the sleeve 53 can correspond one-to-one to the steel bar 6 on the top of the column 1, making it convenient for the sleeve 53 to move to the axis of the annular plate 51 and the axis of the steel bar 6.

[0050] When in use, first place the mounting plate 3 at the top center of the column 1, then fix the outer ring seat 2 on the column 1 by the locking bolt 8, at this time, the sleeve 53 is located above the steel bar 6, and the driving gear 43 is driven to rotate by starting the motor 1 42, thereby driving the slewing support inner gear 44 to rotate, thereby driving the correction component 5 to rotate around the column 1 on the annular slide rail 7, thereby making the sleeve 53 located directly above the steel bar 6, at this time, turn off the motor 1 42, and start the three motors 2 524 at the same time, driving the screw rod 1 522 to rotate, thereby driving the lifting plate 525 to move downward, thereby driving the movable rod 541 to move downward, thereby driving the sleeve 53 to move vertically downward. The steel bar 6 is lowered to allow the steel bar 6 to enter the sleeve 53. At this time, the extrusion wheel 555 has not yet extruded the steel bar 6; then the motor 2 524 is controlled to rotate forward or reversely, so that the movable rod 541 on the corresponding lifting unit 52 can swing with the lifting of the respective lifting plates 525, thereby driving the sleeve 53 to swing, and then the inclined steel bar 6 can be straightened and the steel bar 6 can be preliminarily corrected. This makes it convenient for the sleeve 53 to move downward to prevent the steel bar 6 from tilting too much. When the sleeve 53 descends, the steel bar 6 is easily bent. In addition, after the inclined steel bar 6 is straightened, the bottom of the steel bar 6 can be kept in a vertical state, which facilitates the fitting of the rear extrusion wheel 555 with the surface of the bottom of the steel bar 6;

[0051] After the steel bar 6 is straightened, the three motors 2 524 are started simultaneously to make the sleeve 53 drop to the bottom of the steel bar 6. At this time, the three motors 3 551 are started simultaneously to drive the screw rod 2 552 to rotate, thereby driving the threaded cylinder 553 to move toward the center of the sleeve 53, driving the U-shaped plate 554 to move toward the center of the sleeve 53, and then driving the extrusion wheel 555 to move toward the center of the sleeve 53, so that the three extrusion wheels 555 are closely attached to the surface of the steel bar 6. At least two groups of extrusion wheels 555 in the U-shaped plate 554 are arranged in the vertical direction.

[0052] After the extrusion wheel 555 is in contact with the bottom surface of the steel bar 6, the three motors 2 524 are started simultaneously to raise the sleeve 53, thereby driving the extrusion wheel 555 to rise in the vertical direction. At this time, under the extrusion of the multiple extrusion wheels 555, the bent part of the steel bar 6 is corrected until the sleeve 53 is separated from the steel bar 6, thereby completing the correction operation of the column head steel bar 6;

[0053] Then, three groups of motors 3 551 are started simultaneously to drive screw rod 2 552 to rotate, so that the threaded cylinder 553 is away from the center of the sleeve 53, so that the space between the extrusion wheels 555 is increased, and the next steel bar 6 is convenient to enter; when correcting the next steel bar 6, the motor 1 42 is started again to drive the driving gear 43 to rotate, and then drive the slewing support internal gear 44 to rotate, and then drive the correction component 5 to rotate, so that the sleeve 53 is located directly above the steel bar 6, and then repeat the above-mentioned steel bar 6 correction operation until the steel bars 6 on all the columns 1 are corrected; when using this steel bar 6 correction device, there is no need to manually touch the steel bar 6, which improves safety, and the annular protective enclosure 9 is used to prevent the correction component 5 from injuring nearby personnel, further improving safety.
