Description

Technical Field

[0001] The present invention relates to the field of processing of coiled steel bars, and particularly to a device for improving the safety and efficiency of processing coiled steel bars. Background Art

[0002] In the conventional practice during the processing of coiled steel bars, a square timber or other object is placed under the coiled steel bar, and a steel pipe is passed through the middle as a guide rod.

[0003] However, in the actual construction process, since there is still a large gap between the guide rod and the coiled steel bar, the stability of the pulled-out part of the steel bar is low. As a result, when the coiled steel bar is pulled outward at one end, it is still prone to winding, knotting, and trembling, which affects the smooth progress of subsequent processes and even causes accidental injuries to the staff, and there is room for improvement. Summary of the Invention

[0004] In order to increase the stability of the pulled-out part of the steel bar when pulling the steel bar outward, the present application provides a device for improving the safety and efficiency of processing coiled steel bars.

[0005] The device for improving the safety and efficiency of processing coiled steel bars provided by the present application adopts the following technical solutions:

[0006] A device for improving the safety and efficiency of processing coiled steel bars includes an inclined guide rod, a base is provided at the bottom end of the guide rod, a plurality of outer support rods are arranged at intervals in a spiral shape on the outer wall of the guide rod, and a through hole for the steel bar to pass through is provided at one end of the outer support rod away from the guide rod.

[0007] By adopting the above technical solutions, when pulling the steel bar outward, one end of the steel bar passes through the through holes at one end of the plurality of outer support rods away from the guide rod in sequence and is connected to a straightening device or other devices. The arrangement of the plurality of outer support rods plays a role of supporting and limiting the steel bar, increasing the stability of the pulled-out part of the steel bar, reducing the occurrence of winding, knotting, and trembling of the pulled-out part of the steel bar, and ensuring the smooth progress of subsequent processes.

[0008] Preferably, the outer support rod is hinged to the guide rod, a diagonal brace rod is provided between the guide rod and the outer support rod, the diagonal brace rod is a telescopic rod body, and both ends of the diagonal brace rod are respectively hinged to the guide rod and the outer support rod.

[0009] By adopting the above technical solutions, it is convenient for the staff to adjust the angle of the outer support rod according to the size of the coiled steel bar to adjust the distance between one end of the outer support rod away from the guide rod and the outer support rod. When the outer support rod rotates, the diagonal brace rod rotates and expands and contracts with the outer support rod. After adjusting to a predetermined angle, the diagonal brace rod is locked to a fixed length, and then the outer support rod is supported at a fixed angle.

[0010] Preferably, a bearing is provided at one end of the outer support rod facing away from the guide rod, and the through hole is the inner hole of the bearing.

[0011] By adopting the above technical solution, the setting of the bearing reduces the frictional force between the steel bar and the outer support rod, and reduces the wear when the steel bar moves relative to the outer support rod.

[0012] Preferably, the bottom end of the guide rod is hinged to the base, and a support rod for supporting the guide rod at a fixed angle is provided on the base, and the support rod is a telescopic rod body.

[0013] By adopting the above technical solution, it is convenient for the staff to adjust the angle of the guide rod according to actual needs. The support rod plays a supporting role for the guide rod and restricts the downward rotation of the guide rod.

[0014] Preferably, the base includes a fixed base and an outer support block fixed on the fixed base, and the outer support block is used for abutting against the inner side of the coiled steel bar.

[0015] By adopting the above technical solution, when placing the coiled steel bar, the part of the coiled steel bar that has not been pulled out is placed on the ground and sleeved outside the base, and the outer support block abuts against the inner side of the part of the coiled steel bar that has not been pulled out, increasing the stability of the part of the coiled steel bar that has not been pulled out.

[0016] Preferably, the fixed base includes an annular chassis, a guide rail is detachably connected to the annular chassis, the guide rail is arranged along the radial direction of the annular chassis, a plurality of guide rails are arranged at intervals along the circumferential direction of the annular chassis, the outer support blocks correspond to the annular chassis one by one and are slidably connected to the guide rails, and a locking member for locking the outer support blocks is provided on the guide rails.

[0017] By adopting the above technical solution, it is convenient for the staff to adjust the position of the outer support block according to the actual size of the coiled steel bar, improving the adaptability of the base.

[0018] Preferably, the inner cavity of the guide rod is hollow, one end of the guide rod is connected to the middle position of the fixed base, a connecting rope is connected to the outer support block, the end of the connecting rope facing away from the outer support block extends into the inner cavity of the guide rod, a connecting hole for the connecting rope to extend out is opened on the guide rod, the end of the connecting rope facing away from the outer support block passes through the connecting hole and is connected to the outer support rod. When the outer support block moves away from the guide rod, the outer support rod is turned outwards under the action of the connecting rope, so that the distance between the end of the outer support rod facing away from the guide rod and the guide rod increases, and an elastic member for applying an inward turning force to the outer support rod is provided between the guide rod and the outer support rod.

[0019] By adopting the above technical solution, when the outer support block is pulled outwards so that the outer support block abuts against the inner side of the un-pulled part of the coiled steel bar, the outer support block drives the connecting rope to move, and the connecting rope pulls the outer support rod to rotate, causing the outer support rod to turn outwards. The distance between the end of the outer support rod away from the guiding rod and the guiding rod increases, realizing the synchronous adjustment of the outer support rod when adjusting the outer support block. At the same time, the arrangement of the guide rail detachably connected to the annular chassis facilitates the staff to increase or decrease the number of guide rails according to the number of outer support rods, so that the outer support blocks correspond to the outer support rods one by one.

[0020] Preferably, the elastic member is arranged as a tension spring.

[0021] By adopting the above technical solution, the tension spring applies an inward-turning acting force to the outer support rod, increasing the stability of the outer support rod when rotating under the action of the connecting rope.

[0022] Preferably, the tension spring is sleeved on the outside of the diagonal support rod. One end of the tension spring abuts against the outer support rod, and the other end of the tension spring abuts against the guiding rod.

[0023] By adopting the above technical solution, the connection between the tension spring and the guiding rod and the outer support rod is realized, and the diagonal support rod plays a guiding role for the tension spring, reducing the occurrence of the situation of radial deformation of the tension spring.

[0024] Preferably, the bottom edge of the guiding rod has an arc transition, and the edge of the connecting hole has an arc transition.

[0025] By adopting the above technical solution, the wear of the connecting rope is reduced, and the service life of the connecting rope is prolonged.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. The arrangement of multiple outer support rods plays a role in supporting and limiting the steel bar, increasing the stability of the pulled-out part of the steel bar, reducing the occurrence of the situation of the pulled-out part of the steel bar being entangled and knotted and vibrating, and ensuring the smooth progress of the subsequent process;

[0028] 2. When the outer support block is pulled outwards so that the outer support block abuts against the inner side of the un-pulled part of the coiled steel bar, the outer support block drives the connecting rope to move, and the connecting rope pulls the outer support rod to rotate, causing the outer support rod to turn outwards. The distance between the end of the outer support rod away from the guiding rod and the guiding rod increases, realizing the synchronous adjustment of the outer support rod when adjusting the outer support block. At the same time, the arrangement of the guide rail detachably connected to the annular chassis facilitates the staff to increase or decrease the number of guide rails according to the number of outer support rods, so that the outer support blocks correspond to the outer support rods one by one.

[0033] The following further elaborates on this application Figure 1-2 in conjunction with the attached drawings.

[0034] The embodiment of this application discloses a device for improving the safety and efficiency of coiled bar processing.

[0035] Embodiment 1

[0036] Referring to Figure 1 , a device for improving the safety and efficiency of coiled bar processing includes a base 1, a guide rod 2, and a plurality of outer support rods 3.

[0037] The base 1 is used to connect with the ground or other horizontal working surfaces. The base 1 includes a fixed base 11 and an outer support block 12. In this embodiment, the fixed base 11 is fixed to the ground by anchor bolts, and four outer support blocks 12 are provided at the four end corners of the fixed base 11. When the device is in use, the unpulled part of the coiled bar is sleeved outside the base 1, and the outer support block 12 is used to abut against the inner wall of the coiled bar to maintain the stability of the coiled bar and reduce the displacement of the coiled bar when pulled by an external force.

[0038] The guide rod 2 is inclined, the bottom end of the guide rod 2 is hinged to the base 1, the hinge axis between the guide rod 2 and the base 1 is horizontally arranged, and the guide rod 2 is a circular tube with a hollow inner cavity.

[0039] A vertically arranged support rod 4 is fixed on the fixed base 11. The support rod 4 is a telescopic rod body. A U-shaped seat 5 that abuts against the outer wall of the guide rod 2 is fixed at the top of the support rod 4. The support rod 4 includes a first outer tube 41 and a first inner rod 42. The bottom end of the first inner rod 42 passes through the first outer tube 41 and is slidably connected to the first outer tube 41. A pin hole 43 is provided on both the first inner rod 42 and the first outer tube 41. A plurality of pin holes 43 are vertically spaced on the first inner rod 42. The relative movement of the first inner rod 42 and the outer rod in the vertical direction is restricted by a limit bolt 44 passing through the pin hole 43, and the limit bolt 44 is tightened by a nut threadedly connected to the limit bolt 44.

[0040] To adapt to the extension path of the pulled-out steel bar, a plurality of outer support rods 3 are arranged at intervals in a spiral shape on the outer wall of the guide rod 2. One end of the outer support rod 3 is hinged to the outer wall of the outer support rod 3, and a bearing 31 is fixed at the other end of the outer support rod 3. The inner hole of the bearing 31 is a through hole for the steel bar to pass through.

[0041] An inclined support rod 6 is further provided between the guide rod 2 and the outer support rod 3. Both ends of the inclined support rod 6 are respectively hinged to the outer wall of the guide rod 2 and the outer wall of the outer support rod 3. The inclined support rod 6 is a telescopic rod body. The inclined support rod 6 includes a second outer tube 61 and a second inner rod 62. A pressing bolt 63 for pressing the second inner rod 62 is threadedly connected to the second outer tube 61.

[0042] The implementation principle of an apparatus for improving the safety and efficiency of processing coiled steel bars in an embodiment of the present application is as follows:

[0043] Adjust the guide rod 2 and the outer support rod 3 to an appropriate angle. Support the guide rod 2 through the support rod 4 and place the guide rod 2 to turn downward. By locking the inclined support rod 6 to a fixed length, the rotation of the outer support rod 3 is restricted. When pulling out the steel bar outward, one end of the steel bar passes through the through holes of the bearings 31 on a plurality of outer support rods 3 in sequence and is connected to a straightening device or other devices. The arrangement of the plurality of outer support rods 3 plays a role in supporting and limiting the steel bar, increasing the stability of the pulled-out part of the steel bar, reducing the occurrence of winding, knotting, and trembling of the pulled-out part of the steel bar, and ensuring the smooth progress of subsequent processes.

[0044] Embodiment Two

[0045] Refer to Figure 2 , an apparatus for improving the safety and efficiency of processing coiled steel bars, which is different from Embodiment One in that the fixed base 11 includes an annular chassis 111. The annular chassis is fixed to the ground or other horizontal working surfaces by anchor bolts, and the bottom end of the guide rod 2 is hinged to the middle position of the annular chassis.

[0046] A plurality of guide rails 112 are detachably connected to the annular chassis 111 along its circumferential direction. The guide rails 112 are arranged along the radial direction of the annular chassis 111 . In this embodiment, the guide rails 112 are compressed and connected to the annular chassis 111 by bolts.

[0047] The outer support block 12 corresponds to the guide rail 112 one by one. A guide bar 121 is fixed on the outer support block 12. A guide groove 113 matching the guide bar 121 is opened on the guide rail 112. The guide bar 121 is slidably connected in the guide groove 113. The guide rail 112 is also provided with a locking bolt 114 for locking the guide bar 121.

[0048] The bottom end of the outer support block 12 is connected to the connecting rope 7, the guide rail 112 is provided with a connecting through groove for the connecting rope 7 to pass through, the annular chassis is provided with a clearance groove 116 connected with the connecting through groove, and the guide rod 2 is provided with a connecting hole 21 for the connecting rope 7 to extend out. The end of the connecting rope 7 away from the outer support block 12 passes through the connecting channel 115 and the clearance groove 116 in sequence and then extends into the inner cavity of the guide rod 2, and the end of the connecting rope 7 away from the outer support block 12 passes through the connecting hole 21 and is connected to the outer support rod 3, and the connection between the connecting rope 7 and the outer support rod 3 is located on the opposite side of the connection between the oblique support rod 6 and the outer support rod 3.

[0049] In addition, a tension spring 8 is sleeved on the outer side of the diagonal support rod 6, and the two ends of the tension spring 8 are respectively abutted against the outer support rod 3 and the guide rod 2. The tension spring 8 is used to apply a force to the outer support rod 3 to flip it inward and reduce the angle between the outer support rod 3 and the guide rod 2.

[0050] In order to reduce the wear of the connecting rope 7 during the movement of the connecting rope 7, the bottom edge of the guide rod 2 is in a circular arc transition, and the edge of the connecting hole 21 is in a circular arc transition.

[0051] The implementation principle of the above embodiment is:

[0052] When the outer support block 12 is pulled outward so that it abuts against the inner side of the portion of the coiled round steel bar that has not been pulled out, the outer support block 12 drives the connecting rope 7 to move, and the connecting rope 7 pulls the outer support rod 3 to rotate, causing the outer support rod 3 to flip outward, and the distance between the end of the outer support rod 3 away from the guide rod 2 and the guide rod 2 increases, thereby realizing the synchronous adjustment of the outer support rod 3 when adjusting the outer support block 12. When the outer support block 12 moves to abut against the inner side of the coiled round steel bar, the outer support block 12 is locked to the guide rail 112 by the locking bolt 114; at the same time, the setting of the guide rail 112 detachably connected to the annular chassis 111 makes it convenient for the staff to increase or decrease the number of guide rails 112 according to the number of external support rods 3, so that the outer support block 12 corresponds to the external support rod 3 one by one.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
