It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0037] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0038] like Figure 1-Figure 6 As shown, a straightening device for wire rope processing provided by the present invention comprises a workbench 1, the workbench 1 is fixedly connected with a guide rail 2, the guide rail 2 is slidably connected with a moving assembly 3, the moving assembly 3 can move horizontally along the guide rail 2, both ends of the moving assembly 3 are fixedly connected with a No. 2 motor 11, the output shaft of the No. 2 motor 11 is fixedly connected with an electric pull rod 12, the telescopic end of the electric pull rod 12 is fixedly connected with a fixing sleeve 13 capable of fixing the end of the wire rope, the side wall of the fixing sleeve 13 is threadedly connected with a positioning bolt, one end of the wire rope is inserted into the fixing sleeve 13, and then the positioning bolt is rotated to fix one end of the wire rope to the fixing sleeve 13;

[0039] A base 14 is fixedly provided on the upper end surface of the workbench 1, a rotating sleeve 4 is rotatably provided on the base 14, a driving assembly 5 capable of continuously driving the rotating sleeve 4 to rotate is provided between the rotating sleeve 4 and the base 14, a plurality of pre-straightening mechanisms 6 are fixedly connected to the inner wall of the driving assembly 5 at equal intervals, all the pre-straightening mechanisms 6 can elastically limit the steel wire rope together, an oil delivery mechanism 7 is provided on one side of the pre-straightening mechanism 6, the oil delivery mechanism 7 is connected to the pre-straightening mechanism 6, and when the pre-straightening mechanism 6 is under pressure, the pre-straightening mechanism 6 can drip lubricating oil onto the surface of the steel wire rope;

[0040] The upper end surface of the workbench 1 is also fixedly connected to a sliding seat 15, and a limiting assembly 8 for elastically limiting the sliding seat 15 is arranged between the sliding seat 15 and the workbench 1. The sliding seat 15 is fixedly connected to a frame 16, and the inner wall of the frame 16 is fixedly connected to a plurality of straightening mechanisms 9, all straightening mechanisms 9 are arranged in pairs, and the two straightening mechanisms 9 in each group are arranged oppositely, and all straightening mechanisms 9 can straighten the wire rope together;

[0041] The control system can control the electric pull rod 12 and the fixed sleeve 13 according to the stress conditions of each group of straightening mechanisms 9, thereby improving the straightening effect of the wire rope.

[0042] In this embodiment, the two ends of the steel wire rope to be straightened are fixedly connected to the two fixed sleeves 13 respectively, and the moving assembly 3 is started, so that the moving assembly 3 drives the steel wire rope to move from one side of the workbench 1 to the other side. At this time, the steel wire rope passes through the rotating sleeve 4 and the frame 16 in sequence; in this process, the driving assembly 5 drives the rotating sleeve 4 to rotate, and the rotating sleeve 4 rotates along the direction of the spiral winding of the steel wire rope; in the rotating sleeve 4, all the pre-straightening mechanisms 6 can jointly elastically limit the steel wire rope, so as to perform preliminary straightening on the steel wire rope. At this time, the bent steel wire rope The wire rope squeezes the partial pre-straightening mechanism 6, and the squeezed pre-straightening mechanism 6 drips lubricating oil onto the surface of the bent wire rope. Under the rotation of the rotating sleeve 4, each pre-straightening mechanism 6 can increase the winding effect of the wire rope through friction during the straightening process to prevent the wire rope from being compressed and loosened. When the bending amplitude of the wire rope in some areas is too large, the friction between the wire rope and the pre-straightening mechanism 6 is too large. At this time, the squeezed pre-straightening mechanism 6 drips lubricating oil onto the surface of the bent wire rope, thereby preventing excessive wear on the surface of the wire rope;

[0043] Afterwards, each straightening mechanism 9 in the frame 16 performs secondary straightening on the wire rope. The control system can control the electric pull rod 12 and the fixed sleeve 13 according to the stress conditions of each group of straightening mechanisms 9, thereby improving the straightening effect of the wire rope. The wire rope is straightened by the electric pull rod 12, and the two No. 2 motors 11 can tighten the wire rope when they rotate in opposite directions.

[0044] like Figure 1 As shown, a straightening device for wire rope processing provided by the present invention is provided, wherein the moving component 3 includes a sliding frame 31 and an electric telescopic rod 32, wherein the sliding frame 31 is slidably connected in the guide rail 2, and a telescopic electric telescopic rod 32 is fixedly arranged between the sliding frame 31 and the workbench 1.

[0045] In this embodiment, the electric telescopic rod 32 is started to extend, and the electric telescopic rod 32 pushes the sliding frame 31 to slide along the guide rail 2, and the sliding frame 31 drives the steel wire rope connected thereto to move from one side to the other side of the workbench 1.

[0046] like Figure 2 As shown, a straightening device for wire rope processing provided by the present invention, the driving assembly 5 includes a gear ring 51 and a No. 1 motor 52, the base 14 is fixedly connected to the No. 1 motor 52, the outer ring of the rotating sleeve 4 is provided with a gear ring 51, and the output shaft of the No. 1 motor 52 can engage with the gear ring 51.

[0047] In this embodiment, the first motor 52 is started, and the first motor 52 drives the rotating sleeve 4 to rotate by meshing with the gear ring 51 .

[0048] like Figure 3As shown, a straightening device for wire rope processing provided by the present invention is provided, wherein the pre-straightening mechanism 6 comprises a first electric push rod 61, an elastic rod 62, a first rotating seat 63 and a first limiting roller 64;

[0049] The No. 1 electric push rod 61 is fixedly connected to the inner wall of the rotating sleeve 4, the telescopic end of the No. 1 electric push rod 61 is fixedly connected to an elastic rod 62, the telescopic end of the elastic rod 62 is fixedly connected to a No. 1 rotating seat 63, and the No. 1 rotating seat 63 is rotatably connected to a No. 1 limiting roller 64.

[0050] In this embodiment, each No. 1 electric push rod 61 is started to extend at the same time, and the No. 1 electric push rod 61 drives each No. 1 limit roller 64 connected to it to move closer to the wire rope. When each No. 1 limit roller 64 is in contact with the surface of the wire rope, the No. 1 electric push rod 61 is controlled to stop extending. When the wire rope moves with the sliding frame 31, all the No. 1 electric push rods 61 together elastically limit the wire rope, thereby straightening the bent part of the wire rope.

[0051] Since the wire rope is formed by multiple strands of steel wires spirally wound in one direction, the wire rope is easy to loosen when it is under pressure. In this embodiment, the rotating sleeve 4 drives all the No. 1 limiting rollers 64 to rotate in the direction of the spiral of the wire rope, so that during the straightening process of the wire rope, the No. 1 limiting roller 64 can apply a force in the spiral winding direction of the wire rope, thereby preventing the wire rope from loosening.

[0052] like Figure 3 As shown, a straightening device for wire rope processing provided by the present invention is provided, wherein the oil delivery mechanism 7 comprises an oil tank 71, an oil pipe 72, a first check valve 73 and a second check valve 74;

[0053] The oil tanks 71 are fixedly connected to the inner wall of the rotating sleeve 4, and oil pipes 72 are connected between the oil tank 71 and the elastic rod 62 and between the elastic rod 62 and the No. 1 limiting roller 64. The oil pipe 72 between the oil tank 71 and the elastic rod 62 is provided with a No. 1 one-way valve 73 that is unidirectionally connected to the elastic rod 62, and the oil pipe 72 between the elastic rod 62 and the No. 1 limiting roller 64 is provided with a No. 2 one-way valve 74 that is unidirectionally connected to the No. 1 limiting roller 64, and the No. 1 limiting roller 64 is provided with a plurality of oil outlet holes.

[0054] In this embodiment, when the No. 1 limiting roller 64 is pressed, the No. 1 limiting roller 64 pushes the elastic rod 62 to contract, and the pressure in the elastic rod 62 increases. Under the pressure and the diversion effect of the No. 2 one-way valve 74, the lubricating oil in the elastic rod 62 is output from the oil outlet hole on the No. 1 limiting roller 64 to the surface of the wire rope, thereby lubricating the surface of the wire rope;

[0055] When the pressure on the surface of the No. 1 limiting roller 64 disappears, the No. 1 limiting roller 64 is reset under the push of the internal spring 83. At this time, under the action of pressure and the diversion action of the No. 1 one-way valve 73, the lubricating oil in the oil tank 71 is replenished into the elastic rod 62.

[0056] like Figure 4 As shown, a straightening device for wire rope processing provided by the present invention is provided, wherein the limit assembly 8 comprises a fixing seat 81, a limit rod 82 and a spring 83;

[0057] The guide seat 10 is fixedly connected to the sliding seat 15, and the upper end surface of the workbench 1 is fixedly connected to a fixed seat 81. The fixed seat 81 is fixedly connected to a limiting rod 82. The limiting rod 82 slides and passes through the guide seat 10. A spring 83 is sleeved on the outer side of the limiting rod 82.

[0058] In this embodiment, when the steel wire rope abuts against the straightening mechanism 9 in the frame 16, the steel wire rope pushes the sliding seat 15 to move along the upper end surface of the workbench 1, and the spring 83 can elastically limit the sliding seat 15 together with the guide seat 10, thereby preventing the steel wire rope from rigidly abutting against the straightening mechanism 9 in the frame 16 and getting stuck.

[0059] like Figure 5 As shown, a straightening device for wire rope processing provided by the present invention is provided, wherein the straightening mechanism 9 comprises a second electric push rod 91, a second rotating seat 92 and a second limiting roller 93;

[0060] A plurality of No. 2 electric push rods 91 are fixedly connected to the inner wall of the frame 16 , and a No. 2 rotating seat 92 is fixedly connected to the telescopic end of the No. 2 electric push rod 91 , and a No. 2 limiting roller 93 is rotatably connected to the No. 2 rotating seat 92 .

[0061] In this embodiment, each No. 2 electric push rod 91 is started, and all No. 2 electric push rods 91 jointly drive the No. 2 limiting roller 93 connected thereto to straighten the steel wire rope.

[0062] The present invention provides a straightening device for wire rope processing, wherein the control system comprises:

[0063] The monitoring module includes a first pressure sensor and a second pressure sensor. The first pressure sensor is disposed inside the second electric push rod 91. The first pressure sensor is used to monitor the extrusion force exerted on the second limiting roller 93. The second pressure sensor is disposed at the contact position between the guide seat 10 and the spring 83.

[0064] A storage module, which is used to store the pressure difference between the two No. 1 pressure sensors in each group of two No. 2 electric push rods 91 at the same time, and the pressure value of the No. 2 pressure sensor;

[0065] a processing module, which is used to compare the pressure difference between each group of two No. 1 pressure sensors in the storage module with a preset pressure difference threshold in the processing module and form judgment information, and compare the pressure value of the No. 2 pressure sensor in the storage module with a preset pressure threshold and form judgment information, and the processing module is preferably a computer processor;

[0066] A control module is used to control the second motor 11 and the electric pull rod 12, and the control module is preferably a PLC controller.

[0067] In this embodiment, when the pressure difference between each group of two No. 1 pressure sensors reaches the preset pressure difference threshold in the processing module, and the pressure value of the No. 2 pressure sensor reaches the preset pressure threshold, it means that the bending part of the wire rope is in contact with a No. 2 limit roller 93, and the control module controls the electric pull rods 12 at both ends of the wire rope to contract, thereby increasing the tensile force on the wire rope, further improving the straightening effect of the wire rope, and avoiding the wire rope from being stuck with the straightening mechanism 9 in the frame 16;

[0068] When the pressure difference between each group of two No. 1 pressure sensors does not reach the preset pressure difference threshold in the processing module, and the pressure value of the No. 2 pressure sensor reaches the preset pressure threshold, it means that both sides of the wire rope are in contact with the adjacent No. 2 limit roller 93, and the wire rope becomes loose under the pressure of the No. 1 limit roller 64. At this time, the control module controls the two electric pull rods 12 to contract at the same time, and the two fixed sleeves 13 rotate in opposite directions at the same time, thereby tightening the wire rope and further preventing the wire rope from being stuck with the straightening mechanism 9 in the frame 16.

[0069] Working principle:

[0070] The two ends of the steel wire rope to be straightened are fixedly connected to the two fixing sleeves 13 respectively, and the moving assembly 3 is started, so that the moving assembly 3 drives the steel wire rope to move from one side of the workbench 1 to the other side. At this time, the steel wire rope passes through the rotating sleeve 4 and the frame 16 in sequence;

[0071] During this process, the driving assembly 5 drives the rotating sleeve 4 to rotate, and the rotating sleeve 4 rotates in the direction of the spiral winding of the wire rope; in the rotating sleeve 4, each No. 1 electric push rod 61 is started to extend at the same time, and the No. 1 electric push rod 61 drives each No. 1 limit roller 64 connected to it to move closer to the wire rope. When each No. 1 limit roller 64 is attached to the surface of the wire rope, the No. 1 electric push rod 61 is controlled to stop extending. When the wire rope moves with the sliding frame 31, all the No. 1 electric push rods 61 jointly elastically limit the wire rope, thereby straightening the bent part of the wire rope;

[0072] Since the steel wire rope is formed by multiple strands of steel wires being spirally wound in one direction, the steel wire rope is easy to loosen when it is compressed. In this embodiment, the rotating sleeve 4 drives all the No. 1 limiting rollers 64 to rotate in the direction of the spiral of the steel wire rope, so that during the straightening process of the steel wire rope, the No. 1 limiting roller 64 can apply a force in the spiral winding direction of the steel wire rope, thereby preventing the steel wire rope from loosening; when the bending amplitude of the steel wire rope in some areas is too large, the friction between the steel wire rope and the No. 1 limiting roller 64 is too large, and the No. 1 limiting roller 64 is squeezed and lubricating oil is dripped onto the surface of the bent steel wire rope, thereby preventing excessive wear on the surface of the steel wire rope;

[0073] Afterwards, each straightening mechanism 9 in the frame 16 performs secondary straightening on the steel wire rope, and each No. 2 electric push rod 91 is started, and all No. 2 electric push rods 91 jointly drive the No. 2 limiting roller 93 connected thereto to straighten the steel wire rope;

[0074] When the pressure difference between each group of two No. 1 pressure sensors reaches the preset pressure difference threshold in the processing module, and the pressure value of the No. 2 pressure sensor reaches the preset pressure threshold, the control module controls the electric pull rods 12 at both ends of the wire rope to contract, thereby increasing the tensile force on the wire rope, further improving the straightening effect of the wire rope, and avoiding the wire rope and the straightening mechanism 9 in the frame 16 from getting stuck;

[0075] When the pressure difference between each group of two No. 1 pressure sensors does not reach the preset pressure difference threshold in the processing module, and the pressure value of the No. 2 pressure sensor reaches the preset pressure threshold, the control module controls the two electric pull rods 12 to contract at the same time, and the two fixed sleeves 13 rotate in opposite directions at the same time, thereby tightening the wire rope, further avoiding the jamming of the wire rope and the straightening mechanism 9 in the frame 16, and dripping lubricating oil onto the surface of the bent wire rope through the No. 1 limiting roller 64, which can further reduce the friction between the straightening mechanism 9 and the wire rope.

[0076] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
