Description

Technical Field

[0001] This invention belongs to the technical field of winding equipment and winding busbars, and particularly relates to a three-dimensional insulated tubular busbar winding device and a method for winding the busbar. Background Technology

[0002] In power engineering, tubular busbars are used for conductor connections between power grid transmission lines and substation transformers, jumpers in transmission lines, connecting conductors in power equipment, and overcurrent conductors in high-current DC de-icing devices. In underground substations, subway substations, or substations with certain special requirements, in order to reduce the footprint and make the substation more compact, the insulation performance, corrosion resistance, and other indicators of tubular busbars are required to be greatly improved.

[0003] Currently used tubular busbars are generally straight tubes. A polytetrafluoroethylene (PTFE) film is wound around the outside of the straight tube as an insulation layer, and a semiconductor PTFE film is wound around it as a shielding layer. During winding, the straight tube is fixed on a fixing frame. A slide rail is set on the side of the fixing frame of the straight tube. The winding trolley drives the winding head to move back and forth to complete the winding of the core tube.

[0004] In chemical, mining, and other fields, to save space, insulated tubular busbars are bent along the space between buildings or equipment. These insulated tubular busbars have a curved three-dimensional shape, and the existing straight-tube insulated busbar winding method cannot be used; manual winding is the only option. The two ends of the three-dimensional insulated tubular busbar are fixed to fixing clips, and PTFE film and semiconductor PTFE film are manually wound onto the core tube. This method has the following drawbacks: First, because the core tube of the insulated tubular busbar is curved, the fixed end position is not necessarily horizontal, and the existing fixing clips are not secure enough. During winding, deflection is easy to occur, affecting winding quality and potentially causing injuries or fatalities. Second, because the busbars are uneven in height, workers must use ladders or similar equipment during winding, resulting in high labor intensity, low efficiency, and increased risk of accidents. Third, during winding, uneven winding tension and inconsistent overlap widths between adjacent wrapping films result in poor surface smoothness of the busbar, easy film detachment, and poor product quality and insulation performance. Summary of the Invention

[0005] The first technical problem to be solved by this invention is to provide a three-dimensional insulating tube-type busbar winding device with good winding effect, uniform overlap of adjacent winding films, less tendency to detach, and low labor intensity.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0007] The system includes a busbar fixing frame, a winding trolley track, a winding trolley, a winding robotic arm, a winding head, and a control mechanism. The busbar fixing frame includes a fixed longitudinal slide rail and two transverse slide rails that can move longitudinally along the fixed longitudinal slide rail. A fixed seat is provided on each transverse slide rail, a lifting mechanism is provided on the fixed seat, a fixed mechanism turntable is provided at the top of the lifting mechanism, a fixed card seat is provided on the fixed mechanism turntable, a vertical turntable is provided on the fixed card seat, and a fixed card is provided on the vertical turntable. A slot is provided below the winding trolley, a rack is provided on the winding trolley track, and a first servo motor is provided on the winding trolley to control its forward and backward movement. The winding robotic arm includes a winding upper arm and a winding lower arm. A upper arm turntable is provided on the winding trolley, and an upper arm seat is provided on the upper arm turntable. The winding upper arm and... The boom is connected via a boom pin; a small arm swing seat connected to the boom's rotating shaft is provided at the front end of the winding boom, and a small arm rotating bearing sleeve is provided on the small arm swing seat. The winding small arm is connected to the small arm rotating bearing sleeve via a bearing. A small arm rotating servo motor is provided on the small arm swing seat and connected to the winding small arm; a winding head seat is connected to the front end of the winding small arm via a head rotating shaft, and a head turntable is provided on the winding head seat. The winding head is fixed on the head turntable; the winding head includes a winding motor and a winding head frame, a feeding notch is provided on the winding head frame, a winding turntable poweredly connected to the winding motor is provided on the winding head frame, a film shaft frame, guide wheels, and tension clamps are provided on the winding turntable, and a turntable notch similar to the feeding notch is provided on the winding turntable.

[0008] The second technical problem solved by the present invention is to provide a method for winding a busbar using the above-mentioned three-dimensional insulated tubular busbar winding device.

[0009] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0010] The method includes the following steps:

[0011] The first step is to segment the busbar according to its shape.

[0012] The busbar is divided into straight segments and curved ends according to its shape, and markings are made at the junctions of straight and curved segments, curved and curved segments, and curved and straight segments.

[0013] The second step is to fix the three-dimensional insulated tubular busbar.

[0014] Adjust the position of the two transverse slide rails on the fixed longitudinal slide rail according to the straight distance between the two ends of the busbar. Fix the two transverse slide rails on the fixed longitudinal slide rail. Adjust the position of the fixing seat on the corresponding transverse slide rail according to the position of the two ends of the busbar on the transverse slide rail. Adjust the fixed mechanism turntable and vertical turntable so that the fixing clip is aligned with the position and direction of the end of the busbar. Use the fixing clip to clamp the end of the busbar.

[0015] The third step is to place the busbar into the winding turntable.

[0016] Rotate the winding turntable so that the turntable notch coincides with the feed notch, and put the busbar into the winding turntable from the feed notch;

[0017] Fourth step, pull the winding head along the direction of the busbar and collect the busbar trajectory.

[0018] Step (1): Record the starting point position of the busbar.

[0019] When the winding turntable is located at the starting point of the busbar, the plane of the winding head's winding turntable is perpendicular to the axis of the busbar. The coordinate position at this time is collected by the control mechanism and stored in the control mechanism.

[0020] Step (II): Collect bus track

[0021] Starting from the starting position, the winding turntable is manually pulled to move from the starting position to the end position of the busbar. When the winding turntable reaches each marked symbol position, the plane of the winding head's winding turntable is perpendicular to the axis of the busbar. The coordinate position at this time is collected by the control mechanism and stored in the control mechanism.

[0022] Step (3): Record the position of the busbar endpoint.

[0023] When the winding turntable is at the end position of the busbar, the plane of the winding head's winding turntable is perpendicular to the axis of the busbar. The coordinate position at this time is collected by the control mechanism and stored in the control mechanism.

[0024] Fifth step, reset the rotating disk.

[0025] Pull the winding turntable back from the end point of the busbar to the starting point of the busbar;

[0026] Step 6: Winding the main line

[0027] The winding turntable and control mechanism are activated. The control mechanism controls the winding turntable to move along the busbar according to the busbar trajectory information collected by the control mechanism. While moving, the plane of the winding turntable of the winding head is always perpendicular to the axis of the busbar.

[0028] Step 7: Remove the busbar

[0029] After the winding is complete, cut the wrapping film off the winding turntable, open the retaining clips at both ends of the busbar, and remove the busbar.

[0030] As a further improvement,

[0031] The speed v1 of the winding turntable traveling along the generatrix in the straight section: the speed v2 of the winding turntable traveling along the generatrix axis in the curved section = R:(R+r), where R is the bending radius of the generatrix axis position of the curved section, and r is the radius of the generatrix.

[0032] Compared with the prior art, the three-dimensional insulating tubular busbar winding device and method provided by this invention have the following advantages:

[0033] Firstly, the busbar fixing frame includes a fixed longitudinal slide rail and two transverse slide rails that can move longitudinally along the fixed longitudinal slide rail. A fixing seat is provided on each transverse slide rail, a lifting mechanism is provided on the fixing seat, a fixing mechanism turntable is provided at the top of the lifting mechanism, a fixing bracket is provided on the fixing mechanism turntable, a vertical turntable is provided on the fixing bracket, and a fixing clip is provided on the vertical turntable. In this way, the position of the fixing seat on the corresponding transverse slide rail is adjusted according to the position of the two ends of the busbar on the transverse slide rail. The fixing mechanism turntable and the vertical turntable are adjusted so that the fixing clip is aligned with the position and direction of the end of the busbar. The fixing clip is used to clamp the end of the busbar. This can effectively fix busbars of various shapes.

[0034] Secondly, a slot is provided below the winding trolley, a rack is provided on the winding trolley track, and a first servo motor is provided on the winding trolley to control its forward and backward movement; the winding robotic arm includes a winding upper arm and a winding lower arm, an upper arm turntable is provided on the winding trolley, an upper arm seat is provided on the upper arm turntable, and the winding upper arm and the upper arm seat are connected by an upper arm pin; a lower arm swing seat is provided at the front end of the winding upper arm and connected to the winding upper arm pivot, a lower arm rotating bearing sleeve is provided on the lower arm swing seat, the winding lower arm and the lower arm rotating bearing sleeve are connected by a bearing, and a small... The arm rotation servo motor is connected to the winding arm. A winding head seat is connected to the front end of the winding arm via a head shaft. A head turntable is set on the winding head seat, and the winding head is fixed on the head turntable. The control mechanism adjusts the position of the winding turntable on the busbar and the plane of the winding turntable is perpendicular to the axis of the busbar at that position through the first servo motor, the upper arm turntable, the winding upper arm, the winding arm, the head shaft, and the winding head seat. This results in low labor intensity, high labor efficiency, uniform winding tension, and consistent overlap width between adjacent winding films. For the same batch of busbars, only one busbar trajectory collection is required.

[0035] Thirdly, since the winding head includes a winding motor and a winding head frame, a feeding notch is provided on the winding head frame, and a winding turntable powered by the winding motor is provided on the winding head frame, a film shaft frame, guide wheels and tension clamps are provided on the winding turntable, and a turntable notch similar to the feeding notch is provided on the winding turntable. By rotating the winding turntable, the turntable notch coincides with the feeding notch, and the busbar is put into the winding turntable from the feeding notch. The winding head can be easily removed from the busbar fixed at both ends.

[0036] Fourthly, since the speed v1 of the winding turntable along the generatrix in the straight section is equal to the speed v2 of the winding turntable along the generatrix axis in the curved section (where R is the bending radius of the generatrix axis and r is the radius of the generatrix), during the winding process, adjacent winding films need to overlap to prevent the film from detaching. If the speed v2 of the winding turntable along the generatrix axis in the curved section is equal to the speed v1 of the winding turntable along the generatrix in the straight section, the overlap width of adjacent winding films on the outer side of the curved section is likely to be small or non-overlapping, causing the winding film to fall off. If the ratio between the speed v2 of the winding turntable along the generatrix axis in the curved section and the speed v1 of the winding turntable along the generatrix in the straight section is less than R:(R+r) (where R is the bending radius of the generatrix axis and r is the radius of the generatrix), the overlap width of adjacent winding films on the outer side of the curved section is likely to be too wide, resulting in wasted winding film and a significantly larger diameter in the curved section, affecting the performance.

[0048] The winding robotic arm 4 includes a winding upper arm 18 and a winding lower arm 19. A winding turntable 20 is provided on the winding carriage 3, and an upper arm seat 21 is provided on the upper arm turntable 20. The winding upper arm 18 and the upper arm seat 21 are connected by an upper arm pin 22. A lower arm swing seat 23 is provided at the front end of the winding upper arm 18 and is connected to the rotating shaft of the winding upper arm 18. A lower arm rotation bearing sleeve 24 is provided on the lower arm swing seat 23. The winding lower arm 19 is connected to the lower arm rotation bearing sleeve 24 by a bearing. A lower arm rotation servo motor 25 is provided on the lower arm swing seat 23 and is connected to the winding lower arm 19.

[0049] A winding head base 27 is connected to the front end of the winding arm 19 via a head pivot 26. A head turntable 28 is provided on the winding head base 27, and the winding head 5 is fixed on the head turntable 28. The winding head 5 includes a winding motor 29 and a winding head frame 30. A feed notch 31 is provided on the winding head frame 30. A winding turntable 32, which is powered by the winding motor 29, is provided on the winding head frame. A film shaft frame 33, a guide wheel 34, and a tension clamp 35 are provided on the winding turntable 32. A turntable notch 36, similar to the feed notch 31, is provided on the winding turntable 32.

[0050] The busbar is divided into straight sections and curved ends according to its shape, and markings are made at the junctions of straight and curved sections, curved sections, and straight sections. The positions of the two transverse slide rails 8 on the fixed longitudinal slide rail 7 are adjusted according to the straight-line distance between the two ends of the busbar, and the two transverse slide rails 8 are fixed on the fixed longitudinal slide rail 7. The positions of the fixing seats 9 on the corresponding transverse slide rails 8 are adjusted according to the positions of the two ends of the busbar on the transverse slide rails 8. The fixing mechanism turntable 11 and the vertical turntable 13 are adjusted so that the fixing clip 14 is aligned with the position and direction of the end of the busbar, and the end of the busbar is secured with the fixing clip 14. The winding turntable 32 is rotated so that the turntable notch 36 coincides with the feeding notch 31, and the busbar is placed into the winding turntable 32 through the feeding notch 31. When the winding turntable 32 is at the starting point of the busbar, the plane of the winding turntable 32 of the winding head 5 is perpendicular to the axis of the busbar. The coordinate position at this time is collected by the control mechanism 6 and stored in the control mechanism. 6. Starting from the starting position, manually pull the winding turntable 32 to move it to the end position of the busbar. When the winding turntable reaches each marked point, ensure that the plane of the winding turntable 32 of the winding head 5 is perpendicular to the axis of the busbar. The control mechanism collects the coordinate position at this time and stores the coordinate position in the control mechanism. When the winding turntable is at the end position of the busbar, ensure that the plane of the winding turntable of the winding head is perpendicular to the axis of the busbar. The control mechanism collects the coordinate position at this time and stores the coordinate position of the end position in the control mechanism. Pull the winding turntable 32 back from the end position of the busbar to the starting position of the busbar. Turn on the winding turntable 32 and the control mechanism 6. The control mechanism 6 controls the winding turntable to move along the busbar according to the busbar trajectory information collected by the control mechanism. During the movement, the plane of the winding turntable of the winding head is always perpendicular to the axis of the busbar. After winding is completed, cut the wrapping film from the winding turntable, open the fixing clips at both ends of the busbar, and remove the busbar. It has low labor intensity, high labor efficiency, uniform winding tension, and consistent overlap width between adjacent winding films. For the same batch of busbars, only one busbar trajectory collection is required.

[0051] The method for winding a three-dimensional insulated tubular busbar using the above-mentioned three-dimensional insulated tubular busbar winding device includes the following steps:

[0052] The first step is to segment the busbar according to its shape.

[0053] The busbar is divided into straight segments and curved ends according to its shape, and markings are made at the junctions of straight and curved segments, curved and curved segments, and curved and straight segments.

[0054] The second step is to fix the three-dimensional insulated tubular busbar.

[0055] Adjust the position of the two transverse slide rails 8 on the fixed longitudinal slide rail 7 according to the straight distance between the two ends of the busbar, fix the two transverse slide rails 8 on the fixed longitudinal slide rail 7, adjust the position of the fixing seat 9 on the corresponding transverse slide rail 8 according to the position of the two ends of the busbar on the transverse slide rail 8, adjust the fixing mechanism turntable 11 and vertical turntable 13 so that the fixing clip 14 is aligned with the position direction of the end of the busbar, and use the fixing clip 14 to clamp the end of the busbar.

[0056] The third step is to place the busbar into the winding turntable.

[0057] Rotate the winding turntable 32 so that the turntable notch 36 coincides with the feed notch 31, and put the busbar into the winding turntable 32 from the feed notch 31;

[0058] Fourth step, pull the winding head along the direction of the busbar and collect the busbar trajectory.

[0059] Step (1): Record the starting point position of the busbar.

[0060] When the winding turntable 32 is located at the starting point of the busbar, the plane of the winding turntable 32 of the winding head 5 is perpendicular to the axis of the busbar. The coordinate position at this time is collected by the control mechanism 6 and stored in the control mechanism 6.

[0061] Step (II): Collect bus track

[0062] Starting from the starting position, the winding turntable 32 is manually pulled to move from the starting position to the end position of the busbar. When the winding turntable reaches each marked symbol position, the plane of the winding head 5 winding turntable 32 is perpendicular to the axis of the busbar. The coordinate position at this time is collected by the control mechanism and stored in the control mechanism.

[0063] Step (3): Record the position of the busbar endpoint.

[0064] When the winding turntable is at the end position of the busbar, the plane of the winding head's winding turntable is perpendicular to the axis of the busbar. The coordinate position at this time is collected by the control mechanism and stored in the control mechanism.

[0065] Fifth step, reset the rotating disk.

[0066] Pull the winding turntable 32 from the end point of the busbar back to the starting point of the busbar;

[0067] Step 6: Winding the main line

[0068] Turn on the winding turntable 32 and the control mechanism 6. The control mechanism 6 controls the winding turntable to move along the busbar according to the busbar trajectory information collected by the control mechanism. While moving, the plane of the winding turntable of the winding head is always perpendicular to the axis of the busbar.

[0069] Step 7: Remove the busbar

[0070] After the winding is complete, cut the wrapping film off the winding turntable, open the retaining clips at both ends of the busbar, and remove the busbar.

[0071] During the winding process, to prevent the wrapping film from detaching, adjacent wrapping films need to overlap. The speed v1 of the winding turntable 32 traveling along the straight section of the generatrix and the speed v2 of the winding turntable traveling along the generatrix axis in the curved section of the generatrix satisfy the formula v1:v2=R:(R+r), where R is the bending radius of the generatrix axis position in the curved section, and r is the radius of the generatrix. If the ratio between the speed v2 of the winding turntable traveling along the generatrix axis in the curved section and the speed v1 of the winding turntable traveling along the generatrix in the straight section satisfies the formula R:(R+r)<v1:v2≤1, it is easy to cause the overlap width of adjacent wrapping films on the outer side of the curved section to be small or not overlapped at all, causing the wrapping film to fall off. If the ratio v1:v2 between the speed v2 of the winding turntable traveling along the generatrix axis in the curved section and the speed v1 of the winding turntable traveling along the generatrix axis in the straight section is less than R:(R+r) (where R is the bending radius at the generatrix axis position of the curved section and r is the radius of the generatrix), it is easy to cause the overlap width of the adjacent winding film on the outer side of the curved section to be too wide, resulting in waste of winding film and the diameter of the curved section being significantly too large, affecting the use effect.

[0072] The scope of protection of this invention is not limited to the above embodiments. Any structure that is the same as or similar to the structure of the three-dimensional insulating tubular busbar winding device of this invention, or any method of winding the busbar that is the same as or similar to the method of winding the busbar using this device, falls within the scope of protection of this invention.
