Description

Technical Field

[0001] The invention relates to the technical field of cable processing and manufacturing, and specifically proposes an aluminum alloy cable twisting device. Background Art

[0002] Aluminum alloy stranded cable is a type of wire made from multiple aluminum alloy wires twisted together. It is widely used in power transmission and distribution systems. Aluminum alloy stranded cable can be divided into two types: one consisting of multiple aluminum alloy wires twisted together, and the other consisting of multiple aluminum alloy wires twisted around a steel or copper wire core. The latter type offers increased overall strength compared to the former.

[0003] Under the existing technology, twisted cables are all produced and processed using cable twisting devices. In the twisting device, most of them are equipped with multiple capstans, so that through the synchronous rotation of multiple capstans, multiple cables are driven to twist and form. On the one hand, the capstan plays a role in conveying and guiding the cables, and on the other hand, it is the core driving component of the cable twisting and forming. Before processing, multiple aluminum wires need to be horizontally passed through multiple capstans in sequence and collected on the side of the last capstan before the multiple cables are twisted and formed. In order to ensure the tightness of the cable twisting and winding, multiple cables need to be kept synchronously tensioned. However, after tensioning, the pressing contact force between the aluminum wire and the capstan guide channel during the conveying process will inevitably increase. The aluminum wire is subject to contact wear, especially at the centralized take-up position. The aluminum wire bends due to the take-up, so the wear at the bend and compression point of the aluminum wire will be relatively more serious. In addition, in the existing twisted cable processing process, most of the cables are not effectively lubricated, which does not play a role in reducing friction and cable wear.

[0004] In summary, if aluminum alloy stranded cables experience a certain amount of wear during the stranding and forming process, it will potentially affect the overall strength of the cable and its subsequent service life. Summary of the Invention

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] like Figure 1 and Figure 2 As shown, an aluminum alloy cable twisting device includes a cleaning disk 1, a lubricating disk 2, a wire collecting guide seat 8 and an adjusting mechanism 9; the twisting device provided by the present invention is designed based on the existing cable twisting machine, and also includes a wire-releasing device for releasing each cable in the existing cable twisting machine, a traction device for pulling and conveying the cables, a wire-receiving device for guiding and collecting the twisted cables, and a control system for adjusting equipment parameters, etc., wherein the cleaning disk 1 and the lubricating disk 2 are equivalent to the winches in the existing cable twisting machine, but the number of winches is not limited to the above two, and the wire-receiving guide seat 8 in the present invention is an inlet structure assembled in the existing wire-receiving device for collecting cables in a centralized manner. In addition, it should be noted that the center of the aluminum alloy cable twisted by the twisting device provided by the present invention contains a wire core 01, that is, a plurality of aluminum alloy wires are twisted around the wire core 01; of course, the twisting device provided by the present invention is also suitable for processing and forming aluminum alloy twisted cables that do not contain a wire core 01.

[0034] like Figure 1 、 Figure 3 and Figure 4 As shown, the cleaning disc 1 includes a base disc 11, a cylindrical shaft 111 is welded through the center of the base disc 11, a wire core brush cylinder 12 for cleaning the wire core 01 is embedded and installed along the center axis of the cylindrical shaft 111, and eight aluminum wire brush cylinders 13 distributed circumferentially and cleaned one by one for eight aluminum wires 02 are embedded and installed on the base disc 11; Figure 3 As shown, the left ends of the wire core brush cylinder 12 and the aluminum wire brush cylinder 13 are both provided with an embedding hole along the axis, and the embedding hole of the wire core brush cylinder 12 is embedded with a wire core brush 121 for wrapping and cleaning the wire core 01, and the embedding hole of the aluminum wire brush cylinder 13 is embedded with an aluminum wire brush 131 for wrapping and cleaning the aluminum wire 02. In the present invention, the wire core brush 121 and the aluminum wire brush 131 are both sleeve structures and are made of sponge. When assembling, the wire core brush 121 and the aluminum wire brush 131 only need to be directly plugged into the embedding hole. In actual work, Figure 3The middle cable is twisted and transported to the right. Therefore, the friction between the wire core 01 being transported to the right and the wire core brush 121 causes the wire core brush 121 to be subjected to a rightward reaction force, and the reaction force prevents the wire core brush 121 from sliding out of the embedding hole. Similarly, the aluminum wire brush 131 will not slide out of the embedding hole. When replacement is needed, only the wire core brush 121 and the aluminum wire brush 131 need to be removed from the embedding hole, which is very convenient.

[0035] like Figure 1 、 Figure 3 、 Figure 5 and Figure 6 As shown, the lubrication disk 2 includes a channel disk 3 coaxially arranged with the base disk 11; the channel disk 3 is provided with eight lubrication channels coaxially arranged corresponding to the eight aluminum wire brush cylinders 13, and the channel disk 3 is provided with an inner cavity for pre-storing lubricating liquid and a diversion channel for guiding the lubricating liquid to flow to each lubrication channel; the channel disk 3 includes a liquid storage cylinder shaft 31; the liquid storage cylinder shaft 31 is equipped with a core cylinder 6, the core cylinder 6 includes a guide core 61 embedded in the liquid storage cylinder shaft 31 along the central axis and a fixed cover 62 welded to one end of the guide core 61, the fixed cover 62 is sleeved on one end of the liquid storage cylinder shaft 31 and fixed by bolts, as shown in FIG. Figure 3 As shown, the guide core 61 passes through the left end of the liquid reservoir shaft 31, and the fixed cover 62 is sealed on the right end of the liquid reservoir shaft 31, so that the two ends of the liquid reservoir shaft 31 are in a closed state, and the annular cavity separated by the core tube 6 in the liquid reservoir shaft 31 constitutes an inner cavity for pre-storing lubricating liquid; a spline shaft portion 32 is integrally machined on the liquid reservoir shaft 31, and the spline shaft portion 32 is centrally arranged on the liquid reservoir shaft 31, and eight liquid outlet holes 33 are evenly distributed circumferentially on the spline shaft portion 32, and the liquid outlet holes 33 are centrally arranged relative to the axial ends of the spline shaft portion 32, and the liquid outlet holes 33 pass through radially from the inside of the liquid reservoir shaft 31 to the outside of the spline shaft portion 32.

[0036] like Figure 3 、 Figure 5 、 Figure 6 and Figure 7As shown, a guide core disk 4 is installed on the spline shaft 32 in a key-fitting manner; eight lubrication holes 41 are evenly distributed around the center circumference on the guide core disk 4, and the eight liquid outlet holes 33 are arranged one-to-one with the eight lubrication holes 41. A flow channel gap 42 is provided on the guide core disk 4 between each lubrication hole 41 and the corresponding liquid outlet hole 33, and a guide slot 411 is provided in the lubrication hole 41 to communicate with the corresponding flow channel gap 42; two outer sealing disks 5 assembled in a mirror image are set on the liquid storage cylinder shaft 31, and the guide core disk 4 is clamped between the two outer sealing disks 5, and the disk surfaces on both sides of the guide core disk 4 are Eight positioning guide posts 43 are evenly welded around the circumference. The eight positioning guide posts 43 are evenly spaced and distributed alternately with the eight lubrication holes 41. The eight positioning guide posts 43 on the same side are plugged into an outer sealing disk 5 to achieve the purpose of assembly positioning. A limit cover 51 is set in the center of the outer sealing disk 5. The liquid storage cylinder shaft 31 passes through the limit cover 51. The shaft sections of the liquid storage cylinder shaft 31 located on both sides of the spline shaft 32 are both covered with rubber sealing rings 53. The two sealing rings 53 are assembled with the two outer sealing disks 5. The limit cover 51 is mounted on the spline shaft 32 and sealed at the step of the spline shaft 32 by the sealing rings 53. The outer sealing disk 5 is provided with eight matching holes 52 that correspond to the eight lubrication holes 41. The matching holes 52 and the lubrication holes 41 have the same aperture size. The lubrication holes 41 and the corresponding matching holes 52 on the two outer sealing disks 5 together form a lubrication channel. The flow channel notch 42 and the two outer sealing disks 5 together form a diversion channel.

[0037] like Figure 3 、 Figure 5 and Figure 8 As shown, each lubrication channel is embedded with a lubrication guide cylinder 7 for guiding the aluminum wire 02 to pass through and synchronously brushing lubricating liquid; the lubrication guide cylinder 7 includes a guide cylinder 71, and the guide cylinder 71 is a half-broken structure facing each other perpendicular to the axial direction. The two half-broken structures of the guide cylinder 71 are provided with embedding grooves 711 at the broken surface ends, and a plurality of seepage holes 712 are circumferentially distributed on the guide cylinder 71 at the broken seam. An annular brush 72 is embedded and installed between the embedding grooves 711 of the two half-broken structures of the guide cylinder 71. The annular brush 72 is cylindrical, and the aluminum wire 02 can pass through the annular brush 72. The annular brush 72 is made of sponge or other existing absorbent cotton materials that can replace sponges; the two half-broken structures of the guide cylinder 71 are embedded and installed in the matching holes 52 of the two outer sealing disks 5, one by one, and extend into the corresponding lubrication holes 41, and are fixed to the outer disk surface of the outer sealing disk 5 by screws.

[0038] In order to improve the sealing performance of the assembly between the outer sealing disk 5 and the guide core disk 4, a rubber layer can be attached to both disk surfaces of the guide core disk 4 to avoid holes, or a rubber layer can be attached to both disk surfaces where the outer sealing disk 5 and the guide core disk 4 are in close contact to avoid holes.

[0039] The cleaning disc 1 and the lubricating disc 2 are both used as winches and need to keep rotating synchronously. The base disc 11 and one of the outer sealing discs 5 at the opposite position are horizontally fixedly connected by bolts with eight connecting rods. The eight connecting rods and the eight aluminum wire brush cylinders 13 are evenly distributed in the circumferential direction. In addition, the driving shaft for driving the cleaning disc 1 and the lubricating disc 2 to keep rotating synchronously can be connected to Figure 3 The left end of the middle cylindrical shaft 111.

[0040] It should be noted that the aluminum alloy twisted cable produced by the device of the present invention is a bare conductor. In order to delay the oxidation and corrosion of the cable due to direct exposure to the air, anti-corrosion grease is generally applied on the surface of the cable. The lubricating liquid described in the present invention is specifically the above-mentioned anti-corrosion grease. The anti-corrosion grease is used to form a protective film on the surface of the cable to isolate air, moisture and other corrosive substances, and the anti-corrosion grease usually has a good lubricating effect. In the present invention, the anti-corrosion grease can be pre-injected into the inner cavity of the liquid storage cylinder shaft 31. Since the anti-corrosion grease is a semi-solidified paste at room temperature and does not have fluidity, the resistor can be distributed and installed on the liquid storage cylinder shaft 31. Existing electric heating elements such as wires, or electric heating elements are evenly distributed and installed directly on the two outer sealing disks 5, and the working temperature of the electric heating elements is set to make the anti-corrosion grease at a critical temperature of just melting. The low-temperature heating control method of the electric heating element is a prior art and will not be described here. In addition, in the present invention, in order to be able to apply anti-corrosion grease to the wire core 01 at the same time, the guide core 61 is located in the section of the inner cavity of the liquid storage tube shaft 31 and is distributed with through holes along the radial guide tube. The through hole diameter is 1-2mm and is evenly distributed. At room temperature, the anti-corrosion grease does not have fluidity, and the anti-corrosion grease will not actively flow out from any opening in the channel disk 3.

[0041] like Figure 1 and Figure 3 As shown, the wire collection guide seat 8 and the cleaning disk 1 are distributed on both sides of the lubrication disk 2. The wire collection guide seat 8 is used to centrally guide the collection wire core 01 and the aluminum wire 02. The wire collection guide seat 8 includes a fixed support 81 and a wire collection guide cylinder 82 fixedly assembled on the fixed support 81. The wire collection guide cylinder 82 is coaxially arranged with the lubrication disk 2.

[0042] like Figure 1 、 Figure 3 、 Figure 9 and Figure 10As shown, the adjustment mechanism 9 includes two annular guide frames 91, which are respectively fixed on the base plate 11 and the guide core plate 4; the annular guide frame 91 includes a fixing ring 911 fixed on the base plate 11 and the guide core plate 4 by bolts, and eight circumferentially evenly distributed guide rods 912 are welded on the outer annular surface of the fixing ring 911, and the guide rods 912 are axially arranged along the radial direction of the fixing ring 911; eight adjustment frames 92 are distributed and installed between the two annular guide frames 91, and each adjustment frame 92 is assembled between two horizontally corresponding guide rods 912 on the two annular guide frames 91; the adjustment frame 92 includes a crossbeam plate 921 slidably installed between the two guide rods 912, and two wheel plates are welded on the side end surface of the crossbeam plate 921 facing the center of the base plate 11 Frame 922, and the two wheel frames 922 correspond one to one close to the outlet ends of the aluminum wire 02 arranged on the aluminum wire brush cylinder 13 and the lubrication guide cylinder 7; the two wheel frames 922 are respectively provided with guide wheels 923 for horizontal rotation; a wire pressing rod 924 is hinged at one end of the crossbeam plate 921 close to the channel disk 3, and the hinge hole on the crossbeam plate 921 for hingedly connecting the wire pressing rod 924 is a horizontally extending extended hole; a hinge seat rotating cylinder 93 is horizontally rotatably installed at one end of the fixed support 81 facing the lubrication disk 2 through a seat bearing 931, the hinge seat rotating cylinder 93 is coaxially arranged with the channel disk 3, the hinge seat rotating cylinder 93 is trumpet-shaped, and the eight wire pressing rods 924 are all hinged in the cylinder of the hinge seat rotating cylinder 93, and the end of the wire pressing rod 924 extending into the hinge seat rotating cylinder 93 is a semicircular head structure.

[0043] like Figure 1 、 Figure 3 、 Figure 9 and Figure 10 As shown, the base plate 11 is equipped with a drive assembly 94 that synchronously drives eight adjustment frames 92. The drive assembly 94 is located on the side of the cleaning disk 1 facing away from the lubrication disk 2. The drive assembly 94 includes a drive disk 941 that is rotatably mounted on the cylindrical shaft 111 through a threaded fit; each crossbeam plate 921 is hingedly connected to one end close to the base plate 11 with a connecting rod 942, and the other end of each connecting rod 942 is horizontally welded with a pin shaft 943, and the pin shaft 943 is horizontally penetrated and slidably mounted on the drive disk 941.

[0044] Before processing, such as Figure 3As shown, the wire core 01 passes through the wire core brush cylinder 12, the core cylinder 6 and the wire collection guide cylinder 82 from left to right in sequence, while the aluminum wire 02 passes through the aluminum wire brush cylinder 13, the lubrication guide cylinder 7 and the wire collection guide cylinder 82 from left to right in sequence, and each aluminum wire 02 passes through two guide wheels 923 in sequence, and is pulled and transported from left to right during processing; then, the wire core 01 and the eight aluminum wires 02 are kept synchronously tensioned by the traction device. Obviously, the cable is in a turning position for collection and twisting between the lubrication disk 2 and the wire collection guide seat 8, and the wire core 01 always maintains a straight line transportation, but the aluminum wire 02 is in a bent state due to the winding. Under the traction tensioning state, the aluminum wire 02 is pressed and contacted in the aluminum wire brush cylinder 13, the lubrication guide cylinder 7 and the wire collection guide cylinder 82. In particular, bending friction is generated between the aluminum wire 02 and the lubrication guide cylinder 7 and the wire collection guide cylinder 82, which will increase the wear on the aluminum wire 02. Therefore, the eight aluminum wires 02 can be adjusted synchronously by the adjustment mechanism 9 after tensioning. Specifically:

[0045] The driving disk 941 can be rotated manually, and the driving disk 941 pushes the connecting rod 942 through the pin shaft 943, and the connecting rod 942 further drives the cross beam plate 921 to slide along the two guide rods 912 in the direction away from the center of the base plate 11, and then the two guide wheels 923 synchronously drive the aluminum wire 02 to be slightly pulled in the direction away from the center of the base plate 11, so that the aluminum wire 02 and the aluminum wire brush cylinder 13 and the lubricating guide cylinder 7 are released from the compressed state. At the same time, as the cross beam plate 921 slides, the cross beam plate 921 drives the wire pressing rod 924 to rotate, so that the wire pressing rod 924 extends and closes. The aluminum wire 02 is pressed toward the corresponding position at one end of the hinge rotating cylinder 93, so that there is no direct pressing contact between the aluminum wire 02 and the wire collection guide cylinder 82. Here, the contact area between the aluminum wire 02 and the wire pressing rod 924 is small, so the friction and wear between the aluminum wire 02 and the wire pressing rod 924 is negligible relative to the friction and wear between the aluminum wire 02 and the wire collection guide cylinder 82. In addition, the aluminum wire 02 is made of aluminum alloy material and has a certain toughness and elasticity. Here, the slight deformation of the aluminum wire 02 caused by the side pulling of the adjustment frame 92 is within the range that the aluminum wire 02 can recover by itself.

[0046] After the wiring is completed, the corresponding preparation work can be carried out, for example, the wire core brush 121 and the aluminum wire brush 131 can be replaced, and the lubrication disk 2 can be preheated in advance so that the anti-corrosion grease can reach a fluid state.

[0047] like Figure 3 As shown, the cable is transported from left to right in a twisted and pulled state, and the cleaning disk 1 and the lubrication disk 2 rotate synchronously; when passing through the cleaning disk 1, the core brush 121 performs a wrapping cleaning on the surface of the passed core 01. Similarly, when each aluminum wire 02 passes through the aluminum wire brush cylinder 13, the aluminum wire brush 131 performs a wrapping cleaning on the surface of the aluminum wire 02, which can clean impurities such as oil, dust, etc. on the surface of the core 01 and the aluminum wire 02.

[0048] During the rotation of the lubrication disk 2, the anti-corrosion grease in the liquid storage cylinder shaft 31 melts and flows out along each liquid outlet 33, and then disperses and flows to each diversion channel, flows through the guide slit 411 to the lubrication hole 41, and further penetrates into the annular brush 72 through the seepage hole 712. When the aluminum wire 02 passes through the lubrication guide cylinder 7, the annular brush 72 automatically applies the anti-corrosion grease to the surface of the aluminum wire 02. The anti-corrosion grease applied on the aluminum wire 02 is instantly cooled to a paste due to the heat transfer to the aluminum wire 02, so that the anti-corrosion grease effectively adheres to the aluminum wire 02. In addition, the anti-corrosion grease also penetrates into the core cylinder 6 and is coated on the surface of the wire core 01; the wire core 01 and each aluminum wire 02 are all coated with the anti-corrosion grease after the surface cleaning is completed, and the anti-corrosion grease itself has lubricity, so the wear on the aluminum wire 02 is further reduced during the turning and winding process.

[0049] After passing through the lubrication tray 2, the wire core 01 and the aluminum wire 02 will be collected together in the wire collection guide barrel 82, and will be processed and formed through subsequent twisting.

[0050] Under the existing technology, in the processing of aluminum alloy twisted cables, the anti-corrosion grease is generally applied before twisting or after the cable is twisted and formed. If it is applied before twisting, the wire core 01 and each aluminum wire 02 generally need to be brushed separately, and the brushing is dispersed, which is more inconvenient. If it is applied after twisting, the entire twisted cable is immersed in the anti-corrosion grease, and the overall immersion can basically only adhere to the surface of the cable, and cannot ensure effective penetration into the inner layer of the twisted cable. The inner layer of the twisted cable may not be fully wetted and adhered. In the device provided in the present invention, a cleaning tray 1 and a lubricating tray 2 are distributed. The cleaning tray 1 and the lubricating tray 2 are winch structures improved on the traditional winch. The structures of pre-storage, diversion and dispersed brushing of anti-corrosion grease are integrated on the lubricating tray 2, and the wire core 01 and each aluminum wire 02 can be independently, wrapped and fully brushed. The structure is centralized, and the brushing operation is completed synchronously with the twisting. The cleaning structure for the wire core 01 and each aluminum wire 02 is integrated in the cleaning tray 1, and the cleaning tray 1 is arranged in front of the lubricating tray 2, so that the wire core 01 and each aluminum wire 02 can be cleaned in a wrapped manner before the anti-corrosion grease is applied. The cleaning and brushing intervals are short, and the secondary pollution of the cable surface during the twisting process and synchronous cleaning can be basically avoided, and the adhesion strength and adhesion filling effect of the anti-corrosion grease on the cable surface can be improved.

[0051] In addition, an adjustment mechanism 9 is provided in conjunction with the above-mentioned cleaning and lubrication system, which can synchronously adjust the side pulling and downward pressure of each aluminum wire 02, thereby avoiding the aluminum wire 02 from being in close contact with the aluminum wire brush cylinder 13, the lubrication guide cylinder 7 and the wire collection guide cylinder 82 during the turning and winding process, thereby reducing the wear of the aluminum wire 02 at the source. In the present invention, the wire core 01 and each aluminum wire 02 are coated with anti-corrosion grease before winding, and the lubricity of the anti-corrosion grease itself can further reduce the wear of the aluminum wire 02 during the twisting process.
