Description

Technical Field

[0001] The invention relates to the field of cold and hot straightening of steel wire ropes, and in particular to a cold and hot composite straightening device and method for steel wire ropes. Background Art

[0002] The straightness of wire rope, a core load-bearing component of engineering projects, directly affects its safety and lifespan. It is easy to cause bending and torsional deformation during manufacturing, storage or use, which leads to stress concentration, installation difficulties and operation jitter. Straightening is necessary to restore the geometric accuracy and mechanical properties.

[0003] Traditional straightening adopts a step-by-step process: the wire rope is first manually bent and wound between multiple groups of extrusion wheels for initial straightening, then transferred to an external heating device (such as a resistance furnace) for heating to reduce the straightening resistance, and finally straightened a second time; however, this technology has significant defects: first, manual pre-winding relies on experience, and when dealing with some wire ropes with higher hardness, the wire rope cannot be wound between the extrusion wheels, that is, when dealing with wire ropes with low and high stress, different straightening equipment is required to extrude and straighten them separately; second, the separation of heating and straightening leads to heat energy loss, and the temperature has dropped significantly during straightening, making it impossible to accurately control thermoplastic deformation.

[0004] In the prior art, for example, the patent with publication number CN119304077A discloses a straightening treatment device for wire rope processing, which realizes wire rope straightening through mechanical cold straightening plus dynamic lubrication plus closed-loop regulation: in the pre-straightening stage, multiple sets of elastic limit rollers in the rotating sleeve apply radial pressure to the wire rope, and at the same time, the oil delivery mechanism drips lubricating oil according to pressure feedback to reduce friction damage, and the rotating sleeve rotates in the same direction as the spiral winding direction of the wire rope to avoid looseness; in the secondary straightening stage, the wire rope is squeezed by a pair of straightening mechanisms in the frame, and the control system monitors the pressure in real time and links the electric pull rod and the motor to adjust the tensile force and torque to form a closed-loop straightening control. However, although this technology has improved some of the original problems, there are still aspects that need to be further optimized to better meet actual detection needs.

[0005] This solution has three defects: high dependence on manual labor, limitations in cold straightening, and uneven stress. First, the wire rope needs to be manually inserted into the fixing sleeve and positioned, which is inefficient and difficult to operate for large-diameter / high-hardness wire ropes, and the straightening accuracy is easily affected by placement deviation. Second, it only relies on mechanical pressure for straightening without introducing thermoplastic deformation. Large-diameter wire ropes require higher extrusion pressure, which increases the risk of surface scratches (especially in the pre-straightening friction area). Third, there is no dynamic temperature control design, and the residual stress after cold straightening relies on mechanical stretching for equalization. The lattice distortion cannot be eliminated by recrystallization, resulting in uneven stress distribution.

[0006] Therefore, based on the above-stated viewpoint, there is still room for optimization in the existing technology for straightening the wire rope. Summary of the invention

[0007] To solve the above problems, the present invention provides a wire rope cold and hot composite straightening device, including a base plate. A plurality of sliding grooves are formed on the base plate. A T-shaped plate slides in the sliding grooves. A sliding groove is formed on the T-shaped plate. A transverse plate slides in the sliding groove. Two front and rear corresponding transverse plates form a group, and a straightening component is arranged on the transverse plate.

[0008] On two groups of transverse plates on one side, a wind control unit is arranged, and the wind control unit is used to blow cold air and hot air on the wire rope.

[0009] A rectangular frame for masking the wind control unit is further arranged on the base plate.

[0010] Preferably, the straightening component includes a bending plate arranged on the transverse plate. A plurality of limiting cones are arranged on one side of the bending plate. A rotating shaft rotates on the limiting cone, and a straightening wheel is sleeved on the rotating shaft.

A plurality of air outlet pipes are arranged in a penetrating manner at the lower end of the air storage frame, and the lower ends of the air outlet pipes correspond to the corresponding straightening components.

[0012] Preferably, a blocking component is arranged on the rectangular frame. The blocking component includes a blocking plate hinged on the rectangular frame. A partition plate is arranged in the middle of the rectangular frame, and the corresponding two groups of transverse plates are separated by the partition plate.

[0013] Preferably, arc-shaped grooves corresponding to the hinge axis of the blocking plate are formed on both sides of the rectangular frame and on the partition plate. Three arc-shaped plates located in the corresponding arc-shaped grooves are arranged at the lower end of the blocking plate, and a circular groove corresponding to the straightening wheel is further formed at the end of the arc-shaped plate.

[0014] Preferably, a strip-shaped plate is further arranged on the base plate, and a supporting plate corresponding to the circular groove is arranged on the strip-shaped plate.

[0015] Preferably, a gas supply component for supplying gas to the wind control unit is arranged on the rectangular frame. The gas supply component includes a gas supply pipe penetratingly arranged on one side of the rectangular frame. Telescopic plates are arranged on both sides of the rectangular frame. A bent pipe is arranged on the telescopic plate, and one side of the bent pipe is slidably and penetratingly connected to the gas supply pipe, and the opposite sides of the two bent pipes are slidably and penetratingly connected.

[0016] Preferably, an arc-shaped frame corresponding to the adjacent air storage frame is penetratingly arranged on the other side of the bent pipe, and a strip-shaped groove is formed on the inner diameter of the arc-shaped frame. An air inlet frame corresponding to the strip-shaped groove is penetratingly arranged on one side of the air storage frame close to the adjacent arc-shaped frame.

[0017] Preferably, a cover plate is arranged at the outer end of one side of the air inlet frame close to the arc-shaped frame, and the width and length of the cover plate are greater than the corresponding strip-shaped groove.

[0018] In addition, the present invention also provides a method for cold and hot composite straightening of steel wire ropes, comprising the following steps: S1, straightening adjustment: For the diameter of the steel wire rope, an external force is used to drive the T-shaped plate to move in the corresponding sliding groove.

[0019] S2, wire placement: Place the wire between the straightening components, and again drive the T-shaped plate to drive the straightening components to move towards the wire to clamp the wire.

[0020] S3, wire straightening: Start the straightening components to operate and straighten the steel wire rope. According to the hardness and bending degree of the steel wire rope, an external force drives the cross plate to drive the cross plates in the same group to move, so that the corresponding straightening components are corresponding or intersecting, achieving the purpose of corresponding extrusion and staggered bending extrusion straightening of the wire.

[0021] S4, cold and hot straightening: Start the air control unit to heat the corresponding section of the steel wire rope to further improve the straightening effect. After heating, start the air control unit on the other side to blow cooling air to cool the wire.

[0023] Second, through the staggered movement of the straightening components, the present application can straighten the steel wire rope from multiple angles. The straightening wheels can change their positions and angles under the drive of the cross plate and the T-shaped plate, applying forces in different directions to the steel wire rope, effectively eliminating the bending and twisting of the steel wire rope, ensuring its straightness, and thus improving the straightening quality.

[0024] Third, through the cold and hot alternating treatment of the air control unit, the present application can control the temperature of the steel wire rope during the straightening process. The air control unit provides hot air and cooling air. First, heating is used to improve the plasticity of the steel wire rope, making it easier to straighten; then, cooling air is used to shape it, enhancing strength and toughness, optimizing the straightening effect, and extending the service life of the steel wire rope.

Detailed implementation mode

[0041] The following combines Figures 1 to 14 to describe the embodiments of the present invention in detail.

[0042] The embodiment of the present application discloses a wire rope hot and cold composite straightening device and method, which is mainly applied to the straightening process of wire ropes; by externally driving the key components in the device to adapt to wire ropes of different specifications; then, placing the wire rope at a preset position and clamping it through a mechanical structure; then, starting the straightening assembly to straighten the wire rope; finally, heating and cooling the wire rope through a temperature control device to optimize its physical properties.

[0043] Embodiment 1: Referring to Figure 1 and Figure 2 as shown, it includes a substrate 1, a sliding groove 10, a T-shaped plate 11, a sliding slot 12, a cross plate 13, a straightening assembly 2, a risk control unit 3 and a rectangular frame 14. A plurality of sliding grooves 10 are opened on the substrate 1, and a T-shaped plate 11 slides in the sliding groove 10. A sliding slot 12 is opened on the T-shaped plate 11, and a cross plate 13 slides in the sliding slot 12. That is, when the T-shaped plate 11 is driven by an external force, it can move back and forth in the corresponding sliding groove 10. Similarly, when the cross plate 13 is driven by an external force, it can move left and right in the corresponding sliding slot 12.

[0044] Two corresponding cross plates 13 in the front and back are a group, and a straightening assembly 2 is arranged on the cross plate 13, and the straightening assemblies 2 corresponding to the cross plates 13 are a group.

[0045] On two sets of cross plates 13 on one side, a wind control unit 3 is provided. The wind control unit 3 is used to blow cold air and hot air on the wire rope.

[0046] A rectangular frame 14 for masking the wind control unit 3 is further provided on the base plate 1. When the wind control unit 3 blows hot air or cold air on the wire rope, the rectangular frame 14 is used to play a heat preservation role.

[0047] Combined with the above implementation process, the present invention also provides a method for cold and hot composite straightening of wire ropes, including the following steps: S1, straightening adjustment: According to the diameter of the wire rope, the T-shaped plate 11 is driven to move in the corresponding sliding groove 10 by an external force.

[0048] S2, wire placement: Place the wire between the straightening components 2, and then drive the T-shaped plate 11 to drive the straightening components 2 to move towards the wire again to clamp the wire.

[0049] S3, wire straightening: Start the straightening components 2 to operate to straighten the wire rope, and according to the hardness and bending degree of the wire rope, an external force drives the cross plate 13 to drive the cross plates 13 in the same group to move, so that the corresponding straightening components 2 are corresponding or intersecting, achieving the purpose of corresponding extrusion and staggered bending extrusion straightening of the wire.

[0050] S4, cold and hot straightening: Start the wind control unit 3 to heat the corresponding section of the wire rope to further improve the straightening effect. After heating, start the wind control unit 3 on the other side to blow cooling air to cool the wire.

[0051] Refer to Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, that is, the straightening component 2 for straightening the wire rope; specifically, the straightening component 2 includes a bending plate 20, a limiting cone 21, a rotating shaft 22, a straightening wheel 23 and a straightening motor 24. The bending plate 20 is arranged at the upper end of the cross plate 13. Several limiting cones 21 are arranged on one side of the bending plate 20. A rotating shaft 22 rotates on the limiting cone 21. A straightening wheel 23 is sleeved on the rotating shaft 22. When the rotating shaft 22 is driven by an external force, it can rotate on the corresponding limiting cone 21 and synchronously drive the corresponding straightening wheel 23 to rotate. And in the initial state, the wire rope is placed between two corresponding straightening wheels 23, and then the straightening wheels 23 move towards the wire rope under the drive of the corresponding T-shaped plate 11 to clamp and limit the wire rope. Two corresponding straightening wheels 23 rotate in opposite directions to drive the wire rope to move and achieve the straightening effect.

[0052] Further, if the wire rope is of a soft and thin type and has a large degree of bending, at this time, the straight extrusion force between the two pressing wheels alone cannot completely straighten the wire rope. At this time, the cross plate 13 moves in the sliding groove 12, so that the pressing wheels on the two bending plates 20 are staggered. Then, the T-shaped plate 11 drives the pressing wheels to move towards the wire rope again, forcing the wire rope to bend. At this time, the straightening wheels 23 drive the wire rope to move, which can further improve the straightening effect, and the positions of the straightening wheels 23 can be continuously changed through the movement of the T-shaped plate 11 and the cross plate 13 during the straightening process to achieve the best straightening effect of the wire rope.

[0053] The rotating shafts 22 on the same side are connected by a chain drive. Straightening motors 24 are arranged on the two bending plates 20 through motor bases 612, that is, there is no straightening motor 24 installed on the two corresponding bending plates 20 in the middle.

[0054] The main shaft of the straightening motor 24 is connected to the rotating shaft 22 on one side. The straightening motor 24 can drive the straightening wheels 23 on one side to rotate. The rotating shafts 22 can rotate synchronously through the chain, driving the corresponding straightening wheels 23 to rotate. And the two straightening assemblies 2 on both sides drive the wire rope to move. Even if the middle straightening assembly 2 has no power source of the straightening motor 24, it can also straighten the wire rope.

[0055] Refer to Figure 7 and Figure 11 As shown, that is, the air control unit 3 for blowing cold air and hot air on the wire rope; specifically, the air control unit 3 includes a support plate 30, a gas storage frame 31 and an air outlet pipe 32. The support plate 30 is arranged at the upper end of the bending plate 20, that is, the support plate 30 can move back and forth or left and right along with the bending plate 20.

[0056] A gas storage frame 31 is hinged on the support plate 30. Several air outlet pipes 32 are arranged through the lower end of the gas storage frame 31. The lower ends of the air outlet pipes 32 correspond to the corresponding straightening assemblies 2. The gas storage frame 31 is used to store hot air or cooling gas. For example, during the straightening process, when the wire rope enters between the two middle straightening assemblies 2, at this time, in order to further improve the straightening effect of the wire rope, the hot air in the corresponding gas storage frame 31 can be discharged onto the wire rope through the air outlet pipes 32 to heat the wire rope and achieve the effect of thermal straightening. And during this process, the rectangular frame 14 can play a heat preservation role to prevent hot air from flowing out. And in order to prevent the air pressure inside the rectangular frame 14 from being too high, one-way valves (not shown) are symmetrically arranged on one side of the rectangular frame 14 to timely discharge the excess gas.

[0057] The operator can manually adjust the angle of the air storage frame 31 on the support plate 30, so as to change the air outlet angle of the air outlet pipe 32, so that when the air outlet pipe 32 faces wire ropes of different sizes and types, its end can spray hot air or cooling gas towards the wire rope. And in order to prevent the air storage frame 31 from rotating back to its original position due to gravity after the adjustment is completed, the operator can install a damping component at the hinge joint between the support plate 30 and the air storage frame 31 (an existing device, which can perform damping limit on the hinge point between the air storage frame 31 and the support frame after the air storage frame 31 is adjusted, preventing the air storage frame 31 from rotating to the initial position, and the hinge point will only rotate when the operator applies pressure to the air storage frame 31).

[0058] Continue to refer to Figure 1 and Figure 2 As shown, that is, a blocking component 4 for separately partitioning and blocking the middle and upper ends is provided on the rectangular frame 14; specifically, the blocking component 4 includes a blocking plate 40, a partition plate 41, an arc groove 42, an arc plate 43, a circular groove 44, a strip plate 45 and a supporting plate 46. The blocking plate 40 is hinged to one side of the rectangular frame 14, and a partition plate 41 is arranged in the middle of the rectangular frame 14. The partition plate 41 separates the corresponding two groups of cross plates 13. The blocking plate 40 can block the upper end of the rectangular frame 14. And during the heating or cooling process, the air control unit 3 on one side heats the wire rope. After the heating and straightening are completed, the air control unit 3 on the other side blows cooling air to cool and shape the wire rope.

[0059] Arc grooves 42 corresponding to the hinge axis of the blocking plate 40 are provided on both sides of the rectangular frame 14 and on the partition plate 41. Three arc plates 43 located in the corresponding arc grooves 42 are arranged at the lower end of the blocking plate 40, and circular grooves 44 corresponding to the straightening wheels 23 are further provided at the ends of the arc plates 43.

[0060] That is, when pulling the blocking plate 40 to no longer block the upper end of the rectangular frame 14, at this time, the blocking plate 40 can synchronously drive the arc plate 43 to move out of the arc groove 42. Then, the wire rope is placed from the upper end opening of the arc groove 42 to the bottom of the arc groove 42, and then the blocking plate 40 is closed. At this time, the arc plate 43 moves into the arc groove 42, and the circular groove 44 is used to avoid the wire rope. At this time, the wire rope is limited by the arc groove 42, so that the subsequent straightening assembly 2 can directly clamp the wire rope.

[0061] A strip plate 45 is further provided on the base plate 1, and a supporting plate 46 corresponding to the circular groove 44 is arranged on the strip plate 45. The strip plate 45 is used to support the other end of the wire rope through the supporting plate 46.

[0062] Refer to Figure 8 、 Figure 9 、 Figure 10 and Figure 11As shown, a gas supply assembly 5 for supplying gas to the risk control unit 3 is provided on the rectangular frame 14; specifically, the gas supply assembly 5 includes a gas supply pipe 50, a telescopic plate 51, a bent pipe 52, an arc-shaped frame 53, a strip-shaped groove 54, an air inlet frame 55, and a cover plate 56. The gas supply pipe 50 is provided through one side of the rectangular frame 14, that is, the external end of the gas supply pipe 50 is used to connect to the port of an external gas supply device, and hot gas or cooling gas is supplied into the gas supply pipe 50 by the external gas supply device.

[0063] Telescopic plates 51 are provided on both sides of the rectangular frame 14, and bent pipes 52 are provided on the telescopic plates 51. The telescopic plates 51 are used to support the corresponding bent pipes 52. In the initial state, their telescopic ends will drive the bent pipes 52 to always move towards the middle of the rectangular frame 14, and will perform adaptive telescoping when the bent pipes 52 are driven by an external force. And since the gas supply pipe 50 is slidably connected to the bent pipe 52 on one side, when the bent pipe 52 moves, the gas supply pipe 50 will not move synchronously but remain stationary; and the bent pipe 52 on one side is slidably and through-connected to the gas supply pipe 50, and the opposite sides of the two bent pipes 52 are slidably and through-connected.

[0064] On the other side of the bent pipe 52, an arc-shaped frame 53 corresponding to the adjacent gas storage frame 31 is provided through, and a strip-shaped groove 54 is opened on the inner diameter of the arc-shaped frame 53. On the side of the gas storage frame 31 close to the adjacent arc-shaped frame 53, an air inlet frame 55 corresponding to the strip-shaped groove 54 is provided through. The gas (abbreviation for hot gas and cooling gas) in the gas supply pipe 50 will enter the two corresponding bent pipes 52, then the gas will enter the arc-shaped frame 53 through the bent pipes 52, and then enter the gas storage frame 31 from the strip-shaped groove 54 and the air inlet frame 55, and finally be discharged from the corresponding air outlet pipe 32.

[0065] A cover plate 56 is provided at the outer end of the side of the air inlet frame 55 close to the arc-shaped frame 53. The width and length of the cover plate 56 are greater than the corresponding strip-shaped groove 54, that is, the transverse plate 13 will move in the front-back and left-right directions. Therefore, when the transverse plate 13 indirectly drives the gas storage frame 31 to move back and forth, the gas storage frame 31 will indirectly drive the corresponding bent pipe 52 to move synchronously in the front-back direction through the air inlet frame 55. And when the gas storage frame 31 moves in the left-right direction, at this time the arc-shaped frame 53 will not move. In order to prevent the gas from leaking out of the strip-shaped groove 54 due to the strip-shaped groove 54 and the air inlet frame 55 no longer being completely corresponding, resulting in insufficient exhaust pressure of the arc-shaped frame 53, at this time the strip-shaped groove 54 can be blocked by the cover plate 56. Similarly, when the gas storage frame 31 is adjusted in angle, the cover plate 56 will also block the part of the strip-shaped groove 54 that is not corresponding to the air inlet frame 55.

[0066] It should be noted that when installing the wire rope, in order to prevent the wire rope from being blocked by the bent pipes 52, the two bent pipes 52 are indirectly driven to separate from each other by the movement of the T-shaped plate 11, leaving an installation gap for the wire rope. After the wire rope is installed, the straightening assembly 2 is driven by the T-shaped plate 11 to clamp and limit the wire rope.

[0067] Embodiment 2: Referring to Figure 12 、 Figure 13 and Figure 14 As shown in the figure, on the basis of Embodiment 1, in order to drive the T-shaped plate 11 and the cross plate 13 to move, a driving unit 6 is provided on one side of the base plate 1. Specifically, the driving unit 6 includes a first lead screw 60, a second lead screw 61, a structure groove 62, an annular groove 63, a rotating tooth 64, a transmission shaft 65, a transmission gear 66, a limiting plate 67, a transmission cylinder 68, a connecting shaft 69, a driving groove 610, an extension plate 611, a motor base 612, a driving motor 613, a moving motor 614, a driving key 615, a moving gear 616 and a moving rack 617. Several first lead screws 60 are respectively rotatably inserted through two corresponding front and rear sliding grooves 10, and the first lead screw 60 is in threaded connection with the corresponding two T-shaped plates 11, that is, the threads on the outer side of the first lead screw 60 are symmetrically distributed. When the first lead screw 60 rotates, it can drive the corresponding two T-shaped plates 11 to move in opposite or opposite directions.

[0068] A second lead screw 61 is rotatably inserted through the sliding groove 12, and the second lead screw 61 is in threaded connection with the corresponding cross plate 13. When the second lead screw 61 rotates, it can drive the cross plate 13 to move in the left-right direction.

[0069] A structure groove 62 is further opened on one side of the T-shaped plate 11, and an annular groove 63 located in the structure groove 62 is opened on the outer side of the second lead screw 61. Several rotating teeth 64 distributed around its axis are arranged on the inner diameter of the annular groove 63, and a transmission shaft 65 with one end located in the structure groove 62 is also rotatably inserted through the T-shaped plate 11. A transmission gear 66 meshing with the corresponding rotating teeth 64 is sleeved on the outer side of the transmission shaft 65 located in the structure groove 62.

[0070] When the transmission shaft 65 is driven by an external force, it can drive the transmission gear 66 to rotate in the corresponding structure groove 62. When the transmission gear 66 rotates, it can drive the second lead screw 61 to rotate through the rotating teeth 64 on the inner diameter of the annular groove 63.

[0071] On one side of the rectangular frame 14, limit plates 67 are symmetrically arranged. Six transmission cylinders 68 corresponding to the transmission shafts 65 one by one are rotatably inserted through the two sides of the rectangular frame 14 and the limit plates 67. The inner diameter of the transmission cylinder 68 is in keyway sliding connection with the corresponding transmission shaft 65. The limit plate 67 is used to limit the corresponding transmission cylinder 68. When the transmission cylinder 68 is driven by an external force, it can drive the corresponding transmission shaft 65 to rotate through the keyway fit. Also, because the T-shaped plate 11 moves in the front-back direction, the transmission shaft 65 and the transmission cylinder 68 are in sliding keyway connection. At this time, the transmission shaft 65 can move within the corresponding transmission cylinder 68, while the transmission cylinder 68 does not move.

[0072] Three connecting shafts 69 corresponding to the transmission cylinders 68 one by one are rotatably inserted through the substrate 1. The two sides of the connecting shaft 69 are connected to the corresponding transmission cylinders 68 by belt drive. That is, the connecting shaft 69 can rotate on the substrate 1 and can drive the corresponding two transmission cylinders 68 to rotate synchronously by belt drive when rotating.

[0073] On one side of the first lead screw 60, through the outer wall of the corresponding substrate 1 and at the end of the connecting shaft 69, driving grooves 610 are respectively provided. An extension plate 611 is arranged outside the substrate 1. A motor base 612 slides on the extension plate 611. A driving motor 613 and a moving motor 614 are symmetrically arranged on the motor base 612. A driving key 615 corresponding to several driving grooves 610 is arranged on the main shaft of the driving motor 613. A moving gear 616 is sleeved on the main shaft of the moving motor 614. A moving rack 617 meshing with the moving gear 616 is arranged on the extension plate 611.
