Description

Technical Field

[0002] When the aircraft ground power supplies power to the aircraft, it is necessary to use a power cable to connect the power supply to the aircraft. The power cable is long and heavy, especially for power supply to remote aircraft, the power cable is about 45 meters long. At present, the power cable is retracted and released by manual winding and fixed drum winding. Manual winding is time-consuming and labor-intensive, and the power cable is severely worn. In addition, since the power cable for remote aircraft is long and heavy, it is difficult for ground staff to drag it. The fixed drum generally fixes the power supply and the drum under the bridge or places the power supply and the drum vertical structure on the ground. In this form, the power cable and the aviation plug are dragged and hit on the ground when they are retracted and released, which reduces the service life of the power cable and the aviation plug.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1 To Attachment Figure 7 The utility model is further described.

[0032] A mobile axial-radial combined winding reel comprises: a power supply vehicle 1, a box body 2 is arranged at the upper end thereof, the box body 2 is sealed all around and has a cavity inside, a first wire outlet is arranged at the front end thereof, and a second wire outlet is arranged at the rear end thereof; an axial roller 7 is arranged in the cavity of the box body 2, a spiral groove extending in the axial direction is arranged on the axial roller 7 along the circumferential direction, a driving shaft 9 is coaxially arranged at one end of the axial roller 7, and a support shaft 15 is coaxially arranged at the other end thereof, and the support shaft 15 is a hollow shaft; a radial roller 14 is arranged in the cavity of the box body 2, a wire groove is arranged on the radial roller 14 along the circumferential direction, and the width of the wire groove matches the outer diameter of the radial cable 3, and the radial roller 14 passes through a bearing I 16 is rotatably installed on the support shaft 15; the axial cable 4 is wound in the spiral groove of the axial drum 7, one end of which is connected to the power supply after passing through the second outlet, and the other end is connected to the electrical signal transmission mechanism; the radial cable 3 is wound in the wire groove of the radial drum 14 in the form of stacking layer by layer from the inside to the outside, the inner end of the axial cable 4 is connected to the electrical signal transmission mechanism, and the outer end of the axial cable 4 is connected to the aviation plug 5 after passing through the first outlet, and the axial cable 4 and the radial cable 3 are electrically connected to each other through the electrical signal transmission mechanism; the axial drum driving device is installed in the box body 2, the driving shaft 9 is connected to the axial drum driving device, and the axial drum driving device is used to drive the axial drum to rotate; and the radial drum driving device is installed in the box body 2, and the radial drum driving device drives the radial drum 14 to rotate.

[0033] The structure of the power supply vehicle 1 is prior art, and for details, see Chinese patent: CN217294275U, a self-driving and traction integrated structure for energy storage power supply vehicles. It will not be repeated here. When in use, the power supply vehicle is operated to drive to the aircraft power supply interface. At this time, the axial drum driving device drives the axial drum 7 to rotate, so that the axial cable 4 is unwound. Since the diameter of the axial drum 7 does not change when the axial cable 4 is wound, the unwinding speed of the axial drum 7 is always equal to the driving speed of the power supply vehicle 1, and there is no speed change process. Therefore, the power supply vehicle 1 is more stable in the process of driving and retracting the axial cable 4. When the power supply vehicle drives close to the aircraft, the radial drum driving device drives the radial drum 14 to rotate, thereby realizing the release of the radially wound radial cable 3, and the aviation plug 5 can be plugged into the aircraft to power the aircraft. When the power supply is finished, the aviation plug 5 is unplugged, and the radial drum driving device drives the radial drum 14 to rotate in the opposite direction to realize the retraction of the radial cable 3. During the reverse driving of the power supply vehicle 1, the axial drum driving device drives the axial drum 7 to rotate in the opposite direction to realize the retraction of the axial cable 4. The radial drum 14 is coaxially arranged with the axial drum 7, and the radial cable 3 is electrically connected with the axial cable 4 through an electrical signal transmission mechanism, which simplifies the internal structure of the drum and solves the problem of transitional connection of the cable between the axial drum 7 and the radial drum 14. The axial cable 4 is wound along the axis direction of the axial drum 7, so the cable diameter remains unchanged. When the power supply vehicle 1 is traveling, the pay-off speed of the axial cable 4 is always kept equal to the driving speed of the power supply vehicle 1, ensuring that the axial cable 4 will not be stressed during the process of retracting and releasing the cable, and the power supply vehicle 1 is more stable in driving. After the power supply vehicle 1 is in place, the radial cable 3 wound on the radial drum 14 is used to connect with the aircraft. The method of winding the cable in combination of axial and radial directions can store more cables, and the cable retracting and releasing action can be performed by following the movement of the power supply vehicle 1, which saves the work of manually dragging the cable, saves time and effort, and reduces the wear of the aviation plug 5 and the cable.

[0034] In one embodiment of the utility model, the electric signal transmission mechanism includes a support plate 10 mounted on the drive shaft 9, a main slip ring stator 12 mounted on the support plate 10 and coaxial with the drive shaft 9, a main slip ring rotor 13 rotatably mounted in the main slip ring stator 12, and a rotor support shaft 17 coaxially connected with the main slip ring rotor 13, the main slip ring stator 12 and the main slip ring rotor 13 are coaxial, the rotor support shaft 17 passes through the axial hole of the support shaft 15 and is coaxially connected with a radial drive shaft 18, and the outer side of the radial drive shaft 18 A secondary slip ring rotor 20 is coaxially arranged at the end, a secondary bracket 35 is installed on the inner wall of the box body 2, and a secondary slip ring stator 19 is installed on the secondary bracket 35. The secondary slip ring rotor 20 is rotatably installed in the secondary slip ring stator 19. A terminal block 11 is installed on the support plate 10, one end of the axial cable 4 is connected to the terminal block 11, and the terminal block 11 is electrically connected to the main slip ring stator 12. A terminal post 24 is installed on the radial roller 14, one end of the radial cable 3 is connected to the terminal post 24, and the terminal post 24 is electrically connected to the main slip ring rotor 13. The current signal of the axial cable 4 is transmitted to the terminal block 11, and the terminal block 11 transmits the signal to the main slip ring stator 12. Since the main slip ring stator 12 rotates relative to the main slip ring rotor 13 when the axial drum 7 rotates, the main slip ring stator 12 and the main slip ring rotor 13 are always electrically connected. Since the terminal 24 and the main slip ring rotor 13 are electrically connected to each other, the current signal is transmitted to the radial cable 3, so that the current signal can be transmitted from the axial cable 4 to the radial cable 3 during the mutual movement.

[0035] In one embodiment of the utility model, the axial roller driving device can be the following structure, which includes a reducer 8 installed on the inner wall of the box body 2, the input shaft end of the reducer 8 is drivingly connected to the motor II 31, and the output shaft of the reducer 8 is drivingly connected to the drive shaft 9. The motor II 31 rotates and drives the drive shaft 9 to rotate after the torque is reduced and amplified by the reducer 8, thereby driving the axial roller 7 to rotate, with a simple structure and reliable operation. Further, the reducer 8 can be embedded in the axial roller 7, saving axial space, and can greatly reduce the size of the whole machine.

[0036] In one embodiment of the utility model, the radial roller drive device can be the following structure, which includes a sprocket I 21 installed on the radial drive shaft 18, a connecting plate 23 installed on the radial drive shaft 18, a planetary gear reducer 29 installed in the housing 2, a motor I 30 drivingly connected to the input shaft end of the planetary gear reducer 29, and a main shaft 38 rotatably installed in the housing 2 through a seat bearing, the main shaft 38 is coaxially connected to the output shaft end of the planetary gear reducer 29, the axis of the main shaft 38 is parallel to the axis of the radial drive shaft 18, a sprocket II 39 is installed on the main shaft 38, the connecting plate 23 is connected to the radial roller 14, and the sprocket I 21 and the sprocket II 39 are connected through a chain 22. The motor I 30 rotates, and after the planetary gear reducer 29 reduces the speed and amplifies the torque, the main shaft 38 is driven to rotate, and then the sprocket II 39 is driven to rotate. Since the sprocket II 39 is connected to the sprocket I 21 through the chain 22, the radial drive shaft 18 is driven to rotate, and finally the radial drum 14 is rotated.

[0037] In one embodiment of the utility model, a tensioning sprocket 36 is rotatably mounted in the housing 2, and the tensioning sprocket 36 is engaged with the chain 22 to tension the chain 22. By tensioning the chain 22 with the tensioning sprocket 36, the chain can be prevented from falling off from the sprocket I 21 and the sprocket II 39 during operation, thereby improving the reliability of use.

[0038] In this embodiment, preferably, the main shaft 38 is connected to the output shaft end of the planetary gear reducer 29 in a one-way rotation through the one-way bearing 37. When the motor I 30 rotates forward, the planetary gear reducer 29 drives the main shaft 38 to rotate through the one-way bearing 37 to rotate the radial drum 14 to wind and reel in the wire. When the motor I 30 rotates in the reverse direction, the output shaft of the planetary gear reducer 29 idles and does not drive the main shaft 38 to rotate. That is to say, when the radial cable 3 needs to be released, the radial drum 14 can be driven to rotate. The rotation speed of the radial drum 14 is less than the speed of the reverse rotation of the motor I 30, which can avoid the problem of easy wire jamming caused by electric release, and at the same time, the design of the release limit is omitted, reducing the cost.

[0039] In one embodiment of the utility model, a plug box 6 is installed on the power supply vehicle 1, and the aviation plug 5 is movably inserted into the plug box 6. When the aircraft is not powered, the aviation plug 5 is inserted into the plug box 6 for storage to prevent the aviation plug 5 from being damaged when the power supply vehicle 1 is moved, thereby further improving the reliability of use.

[0040] In one embodiment of the utility model, it also includes a linear guide rail 33 horizontally arranged in the cavity of the box body 2 along the left and right directions and located at the front side ends of the axial roller 7 and the radial roller 14. A slide seat 32 is slidably installed on the linear guide rail 33 along the left and right directions. Two rollers II 27 are rotatably installed at the left and right ends of the slide seat 32, and the axes of the rollers II 27 are perpendicular to the axes of the axial roller 7 and the radial roller 14. Two rollers I 26 are rotatably installed at the upper and lower ends of the slide seat 32, and the axes of the rollers I 26 are parallel to the axes of the axial roller 7 and the radial roller 14. The axial cable 4 passes between the two rollers I 26 and the two rollers II 27. A bearing II 28 is rotatably installed on the rear side of the lower end of the slide seat 32, and the axis of the bearing II 28 is perpendicular to the axes of the axial roller 7 and the radial roller 14. The bearing II 28 is clamped in the spiral groove. When the axial roller 7 of the axial roller driving device rotates, since the bearing II 28 is placed in the spiral groove, the slide 32 moves laterally along the linear guide rail 33 during the rotation of the axial roller 7. Since the axial cable 4 passes between the two rollers I 26 and the two rollers II 27, the slide 32 causes the axial cable 4 to be orderly stuck in the spiral groove during the lateral movement, thereby realizing orderly winding of the cable.

[0041] In this embodiment, further, the left and right ends of the box body 2 are respectively installed with travel switches 34, and when the slide 32 moves to the leftmost end or the rightmost end, it triggers the travel switch 34. The controller of the motor II 31 can be connected to the formation switch 34. When the travel switch 34 is triggered, the motor II 31 stops rotating, and the axial drum 7 stops rotating at this time, thereby stopping the winding and unwinding of the axial cable 4, and realizing automatic control.

[0042] In one embodiment of the utility model, it also includes N rollers 25 arranged in the cavity of the box body 2 and located at the upper ends of the axial roller 7 and the radial roller 14, N is a positive integer greater than or equal to 1, and the left and right ends of the rollers 25 are rotatably mounted on the side walls of the box body 2, and the axis of the rollers 25 is parallel to the axis of the axial roller 7 and the radial roller 14. The rollers 25 are arranged above the axial rollers 7 and the radial rollers 14, so when the axial cable 4 is wound on the axial roller 7 or the radial cable 3 is wound on the radial roller 14, since the rollers 25 play a limiting role above the radial cable 3 or the axial cable 4, it can be ensured that the axial cable 4 is wound on the axial roller 7 in an orderly manner or the radial cable 3 is wound in the radial roller 14 in an orderly manner.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
