Description

Technical Field

[0001] The invention relates to the technical field of stranded wire production, and in particular to a stranding auxiliary device used in the production process of overhead stranded wires. Background Art

[0002] Stranded wire is achieved by twisting single wires around the strand axis at equal angular speeds and moving the strands forward at a uniform speed. Copper and aluminum are commonly used. Copper and aluminum wires can be twisted into conductor cores of various cross-sections and different types of wires and cables. Stranded wire is suitable for high operating frequencies and occasions where the skin effect and proximity effect losses of single-strand wires are too large. Using stranded wire can reduce the operating temperature. Compared with single-strand wires of the same cross-sectional area, stranded wire has higher mechanical properties and flexibility. The stranded wire needs to be rolled up during the stranding production process.

[0003] The Chinese utility model patent with announcement number CN221116436U in the prior art discloses a stranding auxiliary device for the production process of overhead stranded wire, including a base, a support plate fixedly installed on the top of the base, a mounting box rotatably installed on one side of the support plate, and a rotating column fixedly installed on the side of the mounting box close to the support plate, the rotating column passes through the support plate at one end away from the mounting box, a first reduction motor is provided on the side of the support plate away from the mounting box, and the output shaft of the first reduction motor is fixedly connected to the end opposite to the rotating column, and a clamping assembly is provided in the mounting box. The first reduction motor drives the connecting rod and the reciprocating screw rod to rotate synchronously through the linkage assembly, so that the moving block and the support ring move in the same group, and the stranded wire is reciprocated by the support ring, so that the stranded wire is evenly wound on the winding drum, and the stranded wire is prevented from being wound disorderly on the winding drum.

[0004] However, the above patented technology has the following defects, specifically:

[0005] The winding drum is positioned on the installation box by using four radially movable clamping blocks to move from the inside to the outside for tightening and fixing. During installation, the winding drum needs to be axially mounted on the outside of the four clamping blocks first. However, due to the action of gravity, the top inner wall of the winding drum will contact and rest on the clamping block located above, while the bottom inner wall of the winding drum will not contact the clamping block located below. In this way, the downward pressure formed by the weight of the winding drum itself is all concentrated on the surface of the clamping block located above, which will increase the static friction between the winding drum and the surface of the clamping block located above. When the winding drum is moved toward or away from the support plate, the resistance is large, which is time-consuming and labor-intensive. In addition, the winding drum cannot maintain a concentric state with the driving structure when moving axially. Even if it is subsequently fixed by the four clamping blocks, it will affect the dynamic balance of the winding drum during rotation, and thus affect the uniformity of the stranded wire winding on the winding drum.

[0047] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0048] Please combine Figures 1 to 11 The invention discloses a stranding auxiliary device for overhead stranded wire production, comprising a base 1, a side plate 2 is arranged on the top of the base 1, a positioning plate 5 is rotatably arranged on one side of the side plate 2, and a positioning cylinder 6 for sleeves of a winding drum 3 is detachably arranged on one side of the positioning plate 5.

[0049] Two plate-setting grooves 17 are formed on the outer side of the positioning tube 6 away from the end of the positioning plate 5 relative to the axial direction. A guide block 18 is elastically arranged in the plate-setting groove 17 and radially extends out of the groove.

[0050] When the winding drum 3 moves axially to be sleeved on the outside of the positioning cylinder 6, the inner side of the winding drum 3 slides and contacts the guide block 18, so that the guide block 18 is radially pressed into the plate groove 17. Under the guidance of the guide block 18, the winding drum 3 can be concentrically sleeved on the outside of the positioning cylinder 6, ensuring that the winding drum 3 can subsequently maintain concentric rotational motion with the positioning cylinder 6.

[0051] The positioning tube 6 is provided with a locking device, which is driven by the movement of the guide block 18 radially pressed into the plate groove 17 and can lock and fix the positioning tube 6 and the positioning plate 5 .

[0052] A clamping device is provided on the positioning cylinder 6 , and the clamping device is used to clamp and fix the winding reel 3 sleeved on the outer side of the positioning cylinder 6 toward the positioning plate 5 .

[0053] In this embodiment, the guide block 18 can be used to straighten the winding drum 3 when the winding drum 3 is axially inserted on the positioning drum 6 so that it always remains concentric with the positioning drum 6, and improve the insertion efficiency of the winding drum 3 on the positioning drum 6 to ensure dynamic balance during rotation.

[0054] A first connecting rod 19 is radially inserted in the plate groove 17, and the centrifugal end of the first connecting rod 19 is connected to the centripetal side of the guide block 18. A synchronization rod 20 is axially arranged inside the positioning cylinder 6. The centripetal end of the first connecting rod 19 is vertically fixed on the outer wall of one end of the synchronization rod 20, and the outer wall of the synchronization rod 20 is elastically connected to the inner wall of the positioning cylinder 6.

[0055] Two guide wheels 21 are arranged on the outer wall of the positioning cylinder 6 to contact and roll with the inner wall of the winding cylinder 3. A second connecting rod 22 is radially inserted on the outer wall of the positioning cylinder 6. The centrifugal end of the second connecting rod 22 is connected to the axle of the guide wheel 21, and the centripetal end of the second connecting rod 22 is vertically fixed on the outer wall of the other end of the synchronization rod 20.

[0056] In this way, the guide block 18 and the guide wheel 21 on the same synchronization rod 20 can maintain synchronous radial movement.

[0057] A third telescopic rod is provided between the outer wall of the synchronization rod 20 and the inner wall of the positioning tube 6, and a second spring is sleeved on the outer side of the third telescopic rod. When the guide block 18 extends to the outer side of the plate slot 17, the third telescopic rod and the second spring are both in a non-deformed state. When the guide block 18 is radially pressed into the plate slot 17, the third telescopic rod and the second spring are both stretched and deformed.

[0058] The end of the guide block 18 on the centrifugal side and away from the positioning plate 5 has a slope that is slidably pressed against the inner wall of the winding drum 3. The slope can be used to smoothly and stably guide the winding drum 3 when it is axially sleeved.

[0059] Furthermore, the locking device includes a second clamping rod 35 radially inserted inside the positioning ring 7, and a second clamping hole 40 is opened on the outer wall of the first clamping rod 8 to engage with the second clamping rod 35. The second clamping rod 35 is driven by the synchronous centripetal radial movement of the guide wheel 21 and the synchronization rod 20, so that the second clamping rod 35 can penetrate into the first clamping hole 9 and be clamped into the second clamping hole 40, so as to realize the locking and fixation of the positioning cylinder 6 on the positioning plate 5.

[0060] Specifically, a first sleeve 31 is rotatably inserted inside the wall of the positioning cylinder 6, and the first sleeve 31 is sleeved on the outside of the second connecting rod 22. A first spiral groove 32 is axially opened on the inner wall of the first sleeve 31, and a first protrusion 33 that is slidably engaged with the first groove 32 is provided on the outer wall of the second connecting rod 22. A first sprocket 34 is sleeved and fixed on the outer side of the first sleeve 31.

[0061] A second sleeve 36 is inserted into the inner part of the ring wall of the positioning ring 7 for radial rotation, a second sprocket 37 is sleeved and fixed on the outer peripheral side of the second sleeve 36, the first sprocket 34 and the second sprocket 37 are connected by a chain transmission, a second clamping rod 35 is threadedly inserted on the centrifugal end of the second sleeve 36, a synchronous plate 38 is sleeved and fixed on the outer side of the second clamping rod 35, and a first telescopic rod 39 is arranged between the plate surface of the synchronous plate 38 and the inner part of the ring wall of the positioning ring 7.

[0062] In the present example, when the winding reel 3 is axially inserted into the positioning tube 6, it will contact and press the guide block 18, so that the guide block 18 is radially pressed into the plate groove 17. The guide block 18 drives the synchronization rod 20, the second connection rod 22 and the guide wheel 21 to move synchronously in the radial direction through the first connecting rod 19, so that the guide wheel 21 can adapt to the inner tube diameter of the winding reel 3, so that the winding reel 3 can be smoothly and stably inserted into the positioning tube 6. In addition, when the second connecting rod 22 moves radially relative to the first sleeve 31, the first protrusion 33 will rub and squeeze the spiral first groove 32, forcing the first sleeve 31 to rotate. The first sleeve 31 rotates synchronously through the first sprocket 34, the chain, the second sprocket 37, and the second sleeve 36 to interact with the centripetal end of the second clamping rod 35 through threading. Under the joint limiting action of the synchronous plate 38 and the first telescopic rod 39, the centrifugal end of the second clamping rod 35 can be clamped into the second clamping hole 40 to lock and fix the first clamping rod 8 clamped in the first clamping hole 9, thereby realizing the installation and fixation of the positioning cylinder 6 on the positioning plate 5.

[0063] Furthermore, the clamping device includes a fixed plate 10 fixed inside the positioning cylinder 6 and away from the positioning plate 5. A rotating rod 11 is inserted and coaxially rotated on the side of the fixed plate 10 away from the positioning plate 5. A movable plate 12 is sleeved and fixed on the outer side of the rotating rod 11. Two radially extending first limiting grooves 13 are relatively provided on the surface of the fixed plate 10. Two centripetally curved and extending second limiting grooves 14 are relatively provided on the surface of the movable plate 12. First limiting rods 15 parallel to the axial direction of the rotating rod 11 are slidably clamped in the two first limiting grooves 13. A top rod 16 that moves radially along the fixed plate 10 is vertically fixed to the outer wall of the first limiting rod 15.

[0064] A connecting block 23 is fixed to the end of the guide block 18 away from the positioning plate 5. A receiving groove 26 is elastically deflectedly provided at the end of the connecting block 23 away from the guide block 18. A pressure plate 27 is accommodated in the receiving groove 26. A pressure block 29 is inserted into the side of the receiving groove 26 away from its notch.

[0065] The centrifugal end of the ejector rod 16 is respectively slidably pressed against the outer wall of the receiving groove 26 away from the notch and the outer wall of the pressure block 29.

[0066] When the push rod 16 does not contact the receiving groove 26 , the receiving groove 26 is axially parallel to the rotating rod 11 , and the pressing plate 27 is received in the receiving groove.

[0067] When the push rod 16 moves centrifugally and contacts the receiving groove 26, the receiving groove 26 is deflected outward to be perpendicular to the axial direction of the rotating rod 11, and the push rod 16 is offset and parallel to the receiving groove 26. When the push rod 16 continues to move centrifugally, it will contact the pressure block 29, forcing the pressure plate 27 to disengage from the notch of the receiving groove 26 to be crimped to the corresponding end surface of the winding drum 3 away from the positioning plate 5.

[0068] A second limiting rod 28 parallel to the pressure block 29 is inserted on the side of the receiving groove 26 away from its notch. A first spring is sleeved on the outer side of the second limiting rod 28. When the pressure plate 27 is separated from the notch of the receiving groove 26, the first spring is in a compressed deformation state.

[0069] A third connecting rod 25 is fixed to one end of the storage slot 26 close to the connecting block 23. A reel 24 is rotatably inserted on the third connecting rod 25. The reel is rotatably inserted in the reel hole of the outer wall of the connecting block 23. A reel spring is sleeved on the outer side of the reel. The two ends of the reel spring are respectively connected to the outer wall of the reel and the wall of the reel hole.

[0070] The maximum deflection angle of the receiving groove 26 is ninety degrees. When the receiving groove 26 is parallel to the axial direction of the rotating rod 11, the coil spring is in a non-deformed state.

[0071] In this example, after the winding reel 3 is completely assembled on the positioning cylinder 6, the second limiting groove 14 of the movable disk 12 is driven by rotating the rotating rod 11 to rub and squeeze the first limiting rod 15, and under the common limiting action of the first limiting groove 13, the first limiting rod 15 drives the push rod 16 to move radially and centrifugally, which will cause the push rod 16 to first touch the receiving groove 26, forcing the receiving groove 26 to deflect outward from a state parallel to the axial direction of the rotating rod 11 to a vertical state. At this time, the push rod 16 is misaligned and parallel to the vertical receiving groove 26. As the push rod 16 continues to move, it can slide and touch the pressure block 29, which will cause the pressure plate 27 to disengage from the notch of the receiving groove 26 (compression deformation of the first spring) to be crimped to the corresponding end face of the winding reel 3 away from the positioning plate 5, so as to press the winding reel 3 tightly and position it on the positioning ring 7 of the positioning cylinder 6.

[0072] A double-axis reduction motor 41 is installed on the side plate 2, one of the output shafts of the reduction motor 41 passes through the side plate 2 and is connected and fixed at the rotation center of the positioning plate 5, and the other output shaft of the reduction motor 41 is fixed with a third sprocket 42. A rotating shaft 44 parallel to the axial direction of the winding drum 3 is rotatably inserted on the side plate 2, and a fourth sprocket 43 is fixed to one end of the rotating shaft 44. The third sprocket 42 and the fourth sprocket 43 are connected by a chain transmission. A third sleeve 45 is sleeved on the outer side of the rotating shaft 44, and a second groove 46 with a continuous closed loop and an eight-shaped structure is axially opened on the inner wall of the third sleeve 45. A second protrusion 47 that is slidably engaged with the second groove 46 is provided on the outer wall of the rotating shaft 44, and the bottom of the outer wall of the third sleeve 45 is connected to the support ring 4 through a suspension rod, and a second telescopic rod 48 is provided between the suspension rod and the side plate 2.

[0073] In this embodiment, after the winding drum 3 is positioned on the positioning cylinder 6, the stranded wire is passed through the support ring 4 and wound around the side wall of the winding drum 3. The positioning plate 5 and the positioning cylinder 6 are driven to rotate by the reduction motor 41 to drive the winding drum 3 to rotate and pull and reel the stranded wire. The reduction motor 41 will also drive the rotating shaft 44 to rotate synchronously through the third sprocket 42, the chain, and the fourth sprocket 43, so that the second protrusion 47 on the rotating shaft 44 continuously rubs and squeezes the continuous closed loop of the inner wall of the third sleeve 45 and the groove wall of the second groove 46 with an eight-shaped structure, and under the limiting action of the second telescopic rod 48, the third sleeve 45 drives the support ring 4 to move back and forth along the axial direction of the rotating shaft 44 through the suspension rod, so that the stranded wire is evenly wound in the winding drum, which helps to avoid the deviation of the stranded wire during the winding process and avoid the stranded wire from being wound disorderly on the winding drum, thereby achieving the effect of auxiliary wiring and improving the practicality of the equipment.
