Description

Technical Field

[0001] The invention relates to the technical field of steel wire rope manufacturing, in particular to a pre-deformer for producing lifting steel wire ropes. Background Art

[0002] As an important lifting and traction tool, the stability and safety of the performance of wire ropes are crucial for various industrial applications. However, during the production process of wire ropes, due to the influence of various factors such as materials, processes and use environment, wire ropes often have problems such as elastic torsional stress and looseness. These problems not only affect the performance of wire ropes, but also may pose a threat to their safety.

[0003] In order to solve these problems, people have developed various pre-deformers to optimize the structure and performance of wire ropes. A pre-deformer is a device that repeatedly bends and deforms the strands of the wire rope before it is twisted, thereby improving the non-loosening performance and overall strength of the wire rope by eliminating or reducing the stress of the strands.

[0004] However, during the use of traditional pre-deformers, the pre-deformed steel wire rope strands often generate large friction when in contact with the threading holes and deformation rollers, causing wear on the surface of the steel wire rope strands and deformation rollers, affecting the subsequent quality of the steel wire rope strands and reducing the service life of the pre-deformer, increasing production costs. At the same time, when the steel wire rope strands are pre-deformed on the pre-deformer, it is often necessary to lubricate the steel wire rope strands by spraying oil, which is not only cumbersome to operate and reduce lubrication efficiency, but also requires a large amount of steel wire rope lubricating oil to ensure that the surface of the steel wire rope is evenly sprayed with oil, which easily causes waste of lubricating oil, thereby increasing production costs.

DETAILED DESCRIPTION

[0024] To further describe the present invention in detail, the following is an explanation with reference to the accompanying drawings. It is particularly noted that the embodiments described below are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] refer to Figure 1 As shown, a pre-deformer for hoisting wire rope production can be used for pre-deformation of wire rope strands in the manufacturing process of crane wire rope and similar wire ropes. The pre-deformer comprises a base 1, and the outer wall of the base 1 is provided with a first distribution plate 2, a second distribution plate 3, a third distribution plate 4 and a central shaft sleeve 5 in sequence; and a plurality of deformation plates 6 are sequentially sleeved on the central shaft sleeve 5.

[0026] Specifically, the first distribution plate 2, the second distribution plate 3 and the third distribution plate 4 are all provided with a plurality of threading holes 21 arranged in a circular shape. A threading hole sheath 211 is provided in the threading hole 21, and the threading hole sheath 211 is made of polyurethane material. The polyurethane material has good wear resistance and good mechanical strength and bearing capacity, and can reduce the wear of the steel wire strands when passing through the threading hole 21, and prevent the steel wire strands from being damaged by scratches, depressions or fractures caused by friction or extrusion, thereby ensuring the normal subsequent pre-deformation of the steel wire strands.

[0027] A first cushion block 7 is detachably mounted between the deformation disks 6; by disassembling and replacing the first cushion blocks 13 of different lengths, the spacing between the deformation disks 6 can be adjusted, thereby achieving fine control of the pre-deformation degree, thereby improving the pre-deformation accuracy and effect. The outer diameter of the deformation disk 6 decreases in sequence in the direction away from the third distribution disk 4 to form a tapered structure, gradually increasing the deformation strength, making the deformation of the wire rope strand more stable, and helping to gradually increase the compression and tension strength of the crane wire rope during the pre-deformation process to ensure uniform and stable deformation.

[0028] The deformable disk 6 includes a first deformable disk 61, a second deformable disk 62, a third deformable disk 63 and a fourth deformable disk 64 which are sequentially arranged in a direction away from the third distribution disk 4. The first distribution disk 2 is integrally formed with the base 1, the second distribution disk 3 and the third distribution disk 4 are detachably mounted on the base 1, and a second cushion block 8 is arranged between the second distribution disk 3 and the third distribution disk 4, and a third cushion block 9 is arranged between the third distribution disk 4 and the first deformable disk 61. The sizes of the second cushion block 8 and the third cushion block 9 are adjustable and can be removed and replaced.

[0029] The end of the central sleeve 5 is provided with a tightening block 10, and the deformation disks 6 are connected by a deformation adjustment screw 11; the tightening block 5 is sleeved on the deformation adjustment screw 11 and is in close contact with the fourth deformation disk 64. After loosening the deformation adjustment screw 11, the deformation disk 6 and the first cushion block 7 can be disassembled, and the position of the deformation disk 6 can be adjusted, thereby adjusting the deformation of the wire rope.

[0030] refer to Figure 1 and Figure 2 As shown, a plurality of deformation rollers 12 are rotationally symmetrically distributed on the edge of the deformation disk 6 , and the deformation rollers 12 on each deformation disk are arranged one-to-one correspondingly with the threading holes 21 on the first branching disk 2 , the second branching disk 3 or the third branching disk 4 .

[0031] Among them, the deformable disk 6 is provided with a plurality of liquid storage chambers 13 storing steel wire lubricating oil corresponding to the deformable rollers 12, and one side of each liquid storage chamber 13 is provided with a liquid outlet pipe joint 14 connected to the outside. A micro-liquid pump 15 and a micro-telescopic cylinder 16 are provided on both sides of the outside of the deformable disk 6; the liquid outlet pipe joint 14 is connected to the micro-liquid pump 15 through a liquid infusion tube 17. A push plate 18 connected to the micro-telescopic cylinder 16 is provided inside the liquid storage chamber 13, and the micro-telescopic cylinder 16 is used to drive the push plate 18 to approach or move away from the liquid outlet pipe joint 14. In this embodiment, the outer peripheral side of the push plate 18 can be pushed and abutted against the liquid storage chamber 13.

[0032] The steel wire lubricating oil inside the liquid storage chamber 13 can be injected through the liquid outlet pipe joint 14. The micro-liquid pump 15 is connected to the liquid outlet pipe joint 14 through the liquid infusion pipe 17 to form a conveying channel for the steel wire lubricating oil. When the pre-deformer is working, the micro-liquid pump 15 is started, and the steel wire rope lubricating oil is pumped out from the liquid outlet pipe joint 14 through the liquid infusion pipe 17 and conveyed to the next position, and the amount of steel wire lubricating oil inside the liquid storage chamber 13 is gradually reduced. At the same time, as the amount of steel wire lubricating oil inside the liquid storage chamber 13 is gradually reduced, the micro-telescopic cylinder 16 is started to drive the push plate 18 to move toward the direction of the liquid outlet pipe joint 14, thereby compressing and reducing the internal space of the liquid storage chamber 13, so that the compressed space is filled with steel wire lubricating oil as much as possible, so that the micro-liquid pump 15 can fully pump out the steel wire lubricating oil inside the liquid storage chamber 13 through the liquid outlet pipe joint 14 and convey it to the next position. When it is necessary to inject additional wire lubricating oil through the liquid outlet pipe joint 14 , the micro telescopic cylinder 16 is driven in the reverse direction to move the push plate 18 away from the liquid outlet pipe joint 14 , thereby restoring the space of the liquid storage chamber 13 .

[0033] refer to Figure 2 and Figure 3As shown, the deformable roller 12 includes a wheel body 121 and a wheel axle 122 . The wheel body 121 is movably sleeved on one end of the wheel axle 122 , and the other end is detachably mounted on the edge of the corresponding deformable disk 6 .

[0034] A liquid conducting cavity 123 is provided inside the wheel axle 122 below the wheel body 121, and a liquid inlet pipe joint 124 communicating with the outside is provided on one side of the liquid conducting cavity 123; the liquid inlet pipe joint 124 is connected to the micro liquid pump 15 through another infusion tube 17; a plurality of liquid outlet channels 125 communicating with the inside of the liquid conducting cavity 123 are provided inside the wheel body 121, and the liquid outlet channels 125 are rotationally symmetrically distributed around the radial axis of the wheel axle 122, and the liquid outlets of the liquid outlet channels 125 are communicated with the outside.

[0035] The micro-liquid pump 15 pumps the steel wire lubricating oil from the liquid storage chamber 13 through an infusion tube 17, and delivers it through another infusion tube 17, and enters the liquid guide chamber 123 through the liquid inlet pipe joint 124. The volume of the liquid guide chamber 123 is relatively small, and the entered steel wire lubricating oil will be delivered through the liquid outlet channel 125 and flow out from the liquid outlet, thereby automatically lubricating the surface of the wheel body 121 and the surface of the steel wire rope strands in the wheel body 121, which can effectively reduce the friction between the steel wire rope strands and the deformation roller 12 during pre-deformation, and can automatically add steel wire lubricating oil to the surface of the steel wire rope strands, so that a lubricating film is formed on the surface of the steel wire rope strands, which significantly reduces the friction coefficient of the steel wire rope strands during subsequent rope closing and use, and can automatically lubricate while reducing the amount of steel wire lubricating oil, thereby reducing the labor cost and production cost required for lubrication.

[0036] Among them, a plurality of annular liquid storage grooves 126 are arranged around the outer side of the wheel axle 122, and a rotating retaining ring 127 corresponding to the annular liquid storage groove 126 is arranged on the inner side of the wheel body 121. The rotating retaining ring 127 is located in the annular liquid storage groove 126 and rotates with the annular liquid storage groove 126. In addition, a liquid guide port (not shown in the figure) connected to the liquid guide cavity 123 is provided in each of the annular liquid storage grooves 126, and the liquid guide port is connected to the liquid outlet channel 125 through a through hole (not shown in the figure) on the rotating retaining ring 127.

[0037] The wheel body 121 rotates in cooperation with the annular liquid storage tank 126 through the rotating retaining ring 127, so that when the wheel body 121 is in a rotating state, the steel wire lubricating oil in the liquid guide cavity 123 flows out of the liquid guide port into the annular liquid storage tank 126, and penetrates into the through hole on the rotating retaining ring 127, and then flows out from the liquid outlet port of the liquid outlet channel 125, and then the steel wire lubricating oil is coated on the outer surface of the steel wire rope strand and the surface of the wheel body 121, thereby achieving a self-lubricating effect.

[0038] The wheel body 121 is provided with a wheel groove 128, and the liquid outlet channel 125 includes a plurality of first liquid outlet channels 1251, a plurality of second liquid outlet channels 1252 and a plurality of third liquid outlet channels 1253 which are arranged in sequence along the radial axis direction of the wheel axle; and the liquid outlets of the first liquid outlet channel 1251, the second liquid outlet channel 1252 and the third liquid outlet channel 1253 are all located in the wheel groove 128, so that the liquid outlets of the first liquid outlet channel 1251, the second liquid outlet channel 1252 and the third liquid outlet channel 1253 can apply the steel wire lubricating oil to the surface of the steel wire rope strands from three directions, thereby improving the coverage rate of the lubricating oil on the surface of the steel wire rope strands, thereby obtaining a better lubrication effect.

[0039] Preferably, the infusion tube 17 is fixed to the outer side of the corresponding deformation disk 6 by a fixing block 19 to prevent the infusion tube 17 from interfering with the normal transmission and pre-deformation of the steel wire strands. The infusion tube 17 is provided with an infusion tube connector 171 detachably connected to the outlet tube connector 14 or the inlet tube connector 124, so that the infusion tube 17 and the outlet tube connector 14 or the inlet tube connector 124 can be detachably replaced.

[0040] The wheel body 121 is made of tungsten steel, and the outer surface of the wheel body 121 is provided with a wear-resistant coating 20. The wear-resistant coating 20 comprises the following components by weight percentage: 0.8-1.5% cobalt-nickel alloy, 2%-5% aluminum, 8%-12% zinc, and the balance is copper.

[0041] Cobalt-nickel alloy has high hardness and excellent wear resistance, while copper has good toughness. Adding an appropriate amount of cobalt-nickel alloy and copper to the coating can achieve a balance between the hardness and toughness of the coating, so that the coating has both sufficient hardness to resist wear and good toughness to withstand external impact. The addition of zinc and aluminum can adjust the hardness and toughness of the coating to a certain extent. Zinc can play a certain lubricating role in the wear-resistant coating 20, reducing the friction coefficient between the coating and the friction surface, thereby reducing wear. At the same time, the combined effect of cobalt-nickel alloy and aluminum can effectively enhance the corrosion resistance of the wear-resistant coating 20, ensuring that the wear-resistant coating 20 can still maintain stable performance in harsh environments.

[0042] The steps of forming the wear-resistant coating 20 on the outer surface of the wheel body 121 include:

[0043] Step S1 , pretreatment of the outer surface of the wheel body 121 : polishing and cleaning the outer surface of the wheel body 121 to ensure good bonding between the subsequent wear-resistant coating 20 and the wheel body 121 .

[0044] Preferably, step S1 further comprises: electroplating copper on the outer surface of the wheel body after polishing and cleaning, wherein the copper plating layer has a thickness of 1 μm to 2 μm. The electroplated copper layer can be used as a transition layer to further improve the bonding strength between the wheel body 121 and the wear-resistant coating 20 .

[0045] Step S2: Component mixing: Cobalt-nickel alloy powder, aluminum powder, zinc powder and copper powder are selected according to the weight percentage of the components and mechanically mixed in a mixer for 4 to 20 hours, and then dried at a constant temperature of 80°C to 100°C for 8 to 10 hours to obtain copper alloy powder. Mechanical mixing is performed in the mixer for 4 to 20 hours to ensure that the various powders are fully mixed and activated, and the moisture and volatile substances in the powder are removed by constant temperature drying to obtain copper alloy powder.

[0046] Step S3: coating spraying: the mixed copper alloy powder is plasma sprayed to form a wear-resistant coating 20 with a thickness of 1 mm to 3 mm on the outer surface of the wheel body.

[0047] Step S4: coating sintering: the wheel body 121 with the wear-resistant coating 20 is placed in a reducing gas, sintered at 700°C to 900°C for 30-40 minutes, and then naturally cooled in the reducing gas. This helps the metallurgical bonding between the wear-resistant coating 20 and the wheel body 121, and improves the adhesion and wear resistance of the wear-resistant coating 20. Natural cooling in the reducing gas can prevent the wear-resistant coating 20 from cracking and deforming during the cooling process.

[0048] Step S5: Surface treatment of the wear-resistant coating: Smooth and polish the sintered wear-resistant coating 20 until the surface of the wear-resistant coating is flat and smooth, further improving the surface quality and aesthetics of the wear-resistant coating 20, and also helping to reduce the wear of the wear-resistant coating 20 caused by friction with the steel wire rope strands during the use of the wheel body 121.

[0049] By setting the wear-resistant coating 20, the friction between the steel wire rope strands and the surface of the wheel body 121 can be significantly reduced, and the mutual wear between the steel wire rope strands and the wheel body 121 during pre-deformation can be reduced, thereby improving the subsequent steel wire rope manufacturing quality and extending the service life of the wheel body 121.

[0050] The present invention provides a pre-deformer for the production of lifting steel wire ropes. Through the coordinated use of a micro-pump 15 and a micro-telescopic cylinder 16, the steel wire lubricating oil in the liquid storage chamber 13 is automatically extracted and transported to the liquid guide chamber 123, and then flows out through the liquid outlet channel 125 and lubricates the surface of the deformation roller 12 and the steel wire rope strands that enter the deformation roller 12 for deformation, thereby achieving self-lubrication to reduce friction and wear, and reducing the amount of oil required for lubrication to reduce production costs. In addition, a threading hole sheath 211 is provided in the threading hole 21, and a wear-resistant coating 20 is provided on the outer surface of the wheel body 121 to reduce the friction between the pre-deformer and the steel wire rope strands, extend the service life of the pre-deformer, and help reduce production costs and improve production quality.

Obviously, other modifications and changes can be made according to the content of this specification.
