Description

TECHNICAL FIELD

[0001] The utility model belongs to water conservancy and hydropower construction technical field especially a reinforcing steel bar correction device for water conservancy and hydropower construction. BACKGROUND

[0002] In the process of water conservancy and hydropower construction, as the key building material, the quality and shape of reinforcing steel bar directly affect the safety and durability of the project. However, in the process of transportation, storage and use, reinforcing steel bar often bends or deforms to varying degrees, affecting its normal use. In order to restore the straightness of reinforcing steel bar and ensure that it meets the construction standard, a special reinforcing steel bar correction device is needed for processing. The traditional reinforcing steel bar correction device usually adopts a single pushing or clamping structure. Although this design can correct reinforcing steel bar to a certain extent, it has the problems of complex operation, limited application range and poor correction effect.

[0003] The traditional reinforcing steel bar correction device usually only corrects reinforcing steel bar by one-way thrust, that is, only applies force from one direction, lacking the design of providing support from the other side. When reinforcing steel bar is subjected to one-way thrust, stress is concentrated on one side of the reinforcing steel bar, which easily leads to the fracture or deformation of reinforcing steel bar at that part. For example, if a reinforcing steel bar with large diameter is forcibly corrected by one-way thrust at a bending part, due to uneven stress distribution, cracks may be generated near the thrust point or even the reinforcing steel bar may be broken. At the same time, the reinforcing steel bar is easy to slide or deviate during the correction process, resulting in that the corrected reinforcing steel bar still has a certain degree of curvature and cannot meet the expected straightness requirement.

[0005] To achieve the above object, the utility model provides the following technical scheme: A reinforcing steel bar correction device for water conservancy and hydropower construction, including reinforcing steel bar correction work station table, the top surface of reinforcing steel bar correction work station table is provided with reinforcing steel bar correction jig assembly, the bent reinforcing steel bar piece is clamped on reinforcing steel bar correction jig assembly, reinforcing steel bar correction jig assembly includes the U type base fixedly installed on the top surface of reinforcing steel bar correction work station table, the cross -shaped extension bottom plate of symmetry integral connection in the both sides outer wall of U type base, the hydraulic push -rod of horizontal fixed on one side inner wall of U type base, the hydraulic positioning contraction rod of fixed on the other side inner wall of U type base and the correction positioning wheel of symmetry activity setting in the top surface of two cross -shaped extension bottom plate, the bent reinforcing steel bar piece has a bent outer convex end and two reinforcing steel bar free end, the both ends inner wall of bent reinforcing steel bar piece all abut on the outer wall of correction positioning wheel, the pushing end of hydraulic push -rod pushes and abuts on the outer wall of bent outer convex end, the contraction end of hydraulic positioning contraction rod supports and abuts on the inner wall of bent outer convex end, every correction positioning wheel can be rotated on cross -shaped extension bottom plate by bent reinforcing steel bar piece friction push in the correction process, the top surface of every cross -shaped extension bottom plate is symmetrically provided with a plurality of for installing the insertion hole of correction positioning wheel.

[0008] The inner wall of the outer convex clamping block is provided with an arc-shaped clamping groove for clamping the bent outer convex end, and the outer convex end of the outer convex clamping block is provided with an arc-shaped clamping groove for clamping the bent outer convex end.

[0009] The two end outer walls of the U-shaped base and the free end outer walls of each cross-shaped extension bottom plate are integrally connected with mounting ear plates, and each mounting ear plate is fixedly connected together with the reinforcing steel bar correction work station table through bolts.

[0010] The two reinforcing steel free ends are each provided with an inverted U-shaped stroke correction limiting frame, so that the outer wall of the reinforcing steel free end is in sliding frictional contact with the inner top wall of the U-shaped stroke correction limiting frame.

[0011] Preferably, the U-shaped base is symmetrically provided with a plurality of rows of mounting holes on both sides of the top surface of the reinforcing bar straightening station table, and each U-shaped travel straightening limiting frame is connected with the mounting hole at the required position through the second locking bolt knob.

[0012] Compared with the prior art, the technical effects and advantages of the utility model are:

[0013] The hydraulic push rod pushes the bent outer convex end, and the hydraulic positioning contraction rod supports the inner wall from the inside, forming bidirectional clamping. This design not only prevents the reinforcing bar from detaching during the straightening process, but also provides additional support force to avoid the breakage of the reinforcing bar caused by excessive straightening.

The U-shaped travel straightening limiting frame not only prevents the free ends of the reinforcing bar from lifting or deviating from the predetermined path during the straightening process, but also provides additional support and guidance, further improving the straightening accuracy and consistency.

Each U-shaped stroke correction limiting frame 6 is connected with the mounting hole 10 at the desired position through a second locking bolt knob 18, so as to fix the position of the U-shaped stroke correction limiting frame 6. According to the specific length and bending degree of the steel bar, select the appropriate mounting hole 10 position and fix it with the second locking bolt knob 18, providing a variety of installation position selection, adapting to different length and shape of steel bar, enhancing the flexibility and application range of the device, ensuring the stability of the U-shaped stroke correction limiting frame 6 during work, preventing it from loosening or shifting.

[0034] Working principle

[0035] The steel bar correction device for water conservancy and hydropower construction places the bent steel bar to be corrected 7 in the steel bar correction jig assembly 4, ensures that the bent outer convex end 8 of the bent steel bar 7 faces the hydraulic push rod 14, and the free end 9 of the steel bar is located above the cross-extended bottom plate 5. According to the specific bending state of the bent steel bar 7, the position of the correction positioning wheel 12 is adjusted. By loosening the first locking bolt knob 13, the T-shaped insertion column 21 is pulled out of the current insertion hole 20 and inserted into the insertion hole 20 at the appropriate position, and then the first locking bolt knob 13 is tightened to fix the position of the correction positioning wheel 12.

[0036] The inverted U-shaped stroke correction limiting frame 6 is installed above the free end 9 of the steel bar, ensuring that the U-shaped stroke correction limiting frame 6 is aligned with the mounting hole 10 on the steel bar correction workbench 1 and is fixed using the second locking bolt knob 18. This step is used to limit the movement trajectory of the free end 9 of the steel bar during the correction process to prevent it from lifting or leaving the correction device.

[0037] Start the hydraulic push rod 14, make its pushing end drive the outer convex clamping block 15 to abut and clamp the bent outer convex end 8 of the bent steel bar 7, and the hydraulic positioning contraction rod 16 acts synchronously, with its contraction end supported by the inner concave clamping block 17 to abut the inner wall of the bent outer convex end 8. With the continuous pushing force of the hydraulic push rod 14, the bent outer convex end 8 is gradually straightened. In this process, the outer convex clamping block 15 and the inner concave clamping block 17 work together to not only provide clamping force to prevent the bent steel bar 7 from coming off, but also provide additional support force to avoid steel bar breakage due to excessive correction.

[0038] The bent steel bar 7 slides and rubs on the correction positioning wheel 12. With the advancement of the hydraulic push rod 14, the free end 9 of the steel bar swings in an arc within the U-shaped stroke correction limiting frame 6, gradually correcting to be parallel to the cross-extended bottom plate 5. When the bent steel bar 7 is completely corrected, stop the action of the hydraulic system and check whether the steel bar has reached the expected straightness requirement.

[0039] Loosen the first locking bolt knob 13 and the second locking bolt knob 18, remove the U-shaped stroke correction limiting frame 6, and take out the corrected bent steel bar 7.
