[0027] Combined with the attached Figure 1 , attached Figure 2 , attached Figure 3 , attached Figure 4 , attached Figure 5 and attached Figure 9 As shown, an automatic cable reel winding and unwinding vehicle includes a traveling frame 1 and a base 111 on the traveling frame 1. The traveling frame 1 can be caterpillar type or wheel type according to the requirements of the use occasion. A support frame 112 is provided on the base 111, and a cable reel 2 is rotatably provided on the support frame 112. A moving seat 211 for automatically arranging the cable is also provided, and the moving seat 211 is connected to a wire arranging device in the prior art. A cable pulley 212 for guiding the cable is provided on the moving seat 211, and a contact pulley 213 for limiting the upper part of the cable is also provided. Under the combined action of the cable pulley 212 and the contact pulley 213, it can ensure sufficient contact between the cable during winding and unwinding and the cable pulley 212, so as to drive the cable pulley 212 to rotate when winding and unwinding the cable; The number of the cable drums 2 is two, which are respectively located at the upper and lower ends of the support frame 112. The fixed ends of the current collectors on the two cable drums 2 are connected in series through an external cable, so as to ensure the series connection of the cables on the two cable drums 2. A power conversion assembly 3 for enabling the two cable drums 2 to rotate independently or simultaneously is provided on the support frame 112; Connection seats 113 are provided at both ends of the support frame 112 on the base 111. Pressing assemblies 4 for abutting against the cables on the two cable drums 2 are respectively provided on the two connection seats 113. A notch for the cable to extend out is formed on the connection seat 113. Dust-proof strips inclined relatively along the width direction are provided at the upper and lower ends of the notch and jointly form a lateral "eight"-shaped structure, and a distance for the cable to move is left between the two dust-proof strips; The pressing assembly 4 includes a fixed seat 411 provided on the connection seat 113. Upper swing rods 412 and lower swing rods 413 are hinged at both the upper and lower ends of the fixed seat 411. The other ends of the upper swing rod 412 and the lower swing rod 413 are jointly hinged to a swing arm 414. A U-shaped rod 415 is hinged to the other end of the swing arm 414, and a bearing seat 7 is fixedly provided on the U-shaped rod 415. The bearing seat 7 and the axis of the cable drum 2 are on the same horizontal plane. A pressing roller 8 for abutting against the cable is rotatably provided on the bearing seat 7. A balance rod 416 is hinged to the lower swing rod 413. An extension rod 417 hinged to the other end of the balance rod 416 is provided on the U-shaped rod 415. A telescopic rod one 418 with a rebound function is provided on the fixed seat 411, and the movable end of the telescopic rod one 418 is slidably hinged to the lower swing rod 413; In order to ensure the smoothness of the left and right sliding of the bearing seat 7 and the pressing roller 8, the number of the pressing assemblies 4 on each connection seat 113 is two, which are respectively located on the front and rear sides of the corresponding bearing seat 7. A telescopic rod two 419 with a rebound function is also hinged between the inner wall of the connection seat 113 and each upper swing rod 412. The telescopic rod one 418 and the telescopic rod two 419 respectively include a cylinder body and a moving rod slidably matched with the inner wall of the cylinder body. A compression spring is fixedly provided between the bottom surface of the moving rod and the bottom surface of the cylinder body; A cleaning assembly 5 for cleaning the surface of the cable is provided on the moving seat 211. The rotation of the cable pulley 212 drives the cleaning assembly 5 to rotate.

[0028] According to the above structure, when the distance between the fixed power supply point and the electric shovel is relatively far, place this device between the fixed power supply point and the electric shovel. The free end of the cable on one cable reel 2 is connected to the fixed power supply, and the free end of the cable on the other cable reel 2 is connected to the electric shovel. In this way, the length of the cable between the electric shovel and the cable reel 2 can be reduced, thus facilitating the effective control of the tension of the cable. During the process of the cable reel 2 rotating to wind and unwind the cable, the pressing roller 8 presses the cable. During the left and right sliding of the pressing roller 8, the force can be transmitted to the hinge-type U-shaped rod 415, extension rod 417, balance rod 416, swing arm 414, lower swing rod 413, and upper swing rod 412, avoiding the phenomenon of single-point force on the telescopic rod one 418, thereby ensuring the stability of the pressing assembly 4 during long-term use. During the process of winding the cable, it will drive the cable pulley 212 to rotate, and then drive the cleaning assembly 5 to rotate, which can clean the dust on the surface of the cable during the winding process and improve the cleanliness requirements of the cable surface.

[0029] Combined with the attached Figure 2 and the attached Figure 6 As shown, the power conversion component 3 includes a U-shaped frame 311 arranged on the support frame 112. A speed regulating motor 312 is provided between the two cable reels 2 on the U-shaped frame 311. A gear one 313 is provided on the output shaft of the speed regulating motor 312. Spline shafts one 314 that are rotationally matched with the U-shaped frame 311 are respectively provided on the input shafts of the two cable reels 2. Gear two 315 that is slidably matched with each of the two spline shafts one 314 is respectively provided on the two spline shafts one 314. Extension parts 316 are respectively provided on the two gear two 315, and adjusting cylinders one 317 are rotatably provided on the extension parts 316. External threads are provided on the extension parts 316, and slotted nuts one 320 that block the adjusting cylinders one 317 are sleeved on the external threads. Adjusting members for controlling the sliding of the adjusting cylinders one 317 are respectively provided on the U-shaped frame 311 and the support frame 112. The adjusting members are electric push rods two 318, and the movable ends of the electric push rods two 318 are respectively connected to the corresponding adjusting cylinders one 317. A sealing plate 319 for enclosing the power conversion component 3 is further provided on the U-shaped frame 311.

[0030] The working principle of the power conversion component 3 is as follows: Control the upper electric push rod two 318 to extend, which will drive the connected adjusting cylinder one 317 to slide forward, and then drive the upper gear two 315 to slide forward to engage with the gear one 313. Start the speed regulating motor 312 to drive the gear one 313 to rotate, and then drive the upper gear two 315 and the cable reel 2 to rotate to wind and unwind the cable above it. Similarly, control the lower electric push rod two 318 to extend, which can make the lower gear two 315 and the gear one 313 engage, and then drive the lower cable reel 2 to rotate; When the two cable reels 2 rotate separately, the distances between the device and the fixed power supply point and the electric shovel can be adjusted and controlled respectively. After the device is used up and the cables on the upper and lower cable reels 2 need to be wound up, the upper and lower second gears 315 are both engaged with the first gear 313, the speed regulating motor 312 is started, and at the same time, the traveling frame 1 is controlled to move towards the fixed power supply point. At this time, the upper and lower cable reels 2 will rotate simultaneously, the cable connected to the electric shovel will unwind, and the cable connected to the fixed power supply point will wind up. In this way, the cable connected to the fixed power supply can be wound up. After the winding is completed, the power is then transferred to the cable reel 2 connected to the electric shovel, the cable reel 2 is controlled to rotate, and at the same time, the traveling frame 1 is controlled to move towards the electric shovel, so that the cable connected to the electric shovel can be wound up. In this way, the cable is always above the ground during the entire winding process, avoiding the phenomenon of the surface of the cable rubbing against the ground during the winding process.

[0031] Combined with the attached Figure 7 Attachments Figure 8 Attachments Figure 9 And attachments Figure 10 As shown, since there is a lot of dust during the open-pit mining process, dust will fall on the surface of the unwound cable. In order to clean the dust on the surface of the cable during the winding process, a cleaning component 5 is also provided. The cleaning component 5 includes support seats 511 provided on the moving seat 211 and located on both sides of the cable. Two brush rollers 512 are rotatably provided on the two support seats 511 respectively, and bristles 513 are equidistantly arranged along the circumferential direction on the brush rollers 512, and the bristles 513 are made of a flexible material. A connecting and disconnecting component 6 is provided between the cable pulley 212 and the brush roller 512 to drive or separate the rotation of the two. The connecting and disconnecting component 6 includes a worm 611 rotatably provided on the moving seat 211 and coaxial with the cable pulley 212, and a worm gear 612 meshing with the worm 611 is also provided. A second spline shaft 613 is provided on the output shaft of the worm gear 612, and a third spline shaft 614 is provided on the input shaft of the brush roller 512. A spline cylinder 615 that cooperates with the second spline shaft 613 and the third spline shaft 614 is slidably provided on the moving seat 211. An adjusting cylinder 616 is rotatably provided on the spline cylinder 615. The spline cylinder 615 is provided with an external thread, and a slotted nut 619 that blocks the adjusting cylinder 616 is provided on the external thread. An electric push rod 617 for controlling the sliding of the adjusting cylinder 616 is provided on the moving seat 211. The power supply of the electric push rod 617 is through the sliding contact wire provided on the connecting seat 113. In order to avoid a large amount of dust staying on the bristles 513, a contact rod 618 that blocks the bristles 513 and causes an inclined deformation is also provided on the moving seat 211.

[0032] The working principle of the rotation of the cleaning assembly 5 is as follows. When the cable reel 2 pays out the cable, the first electric push rod 617 is controlled to extend, driving the spline cylinder 615 to move to the left, so that the spline cylinder 615 is separated from the second spline shaft 613. At this time, the rotation of the cable pulley 212 does not drive the brush roller 512 to rotate. When the cable reel 2 winds up the cable, the first electric push rod 617 is controlled to contract, driving the spline cylinder 615 to move to the right, so that the spline cylinder 615 cooperates with the third spline shaft 614 and the second spline shaft 613 at the same time. At this time, during the process of winding up the cable, the cable pulley 212 will be driven to rotate, then the worm 611 will be driven to rotate, and then the worm gear 612 will be driven to rotate. Then the second spline shaft 613, the spline cylinder 615 and the third spline shaft 614 will be driven to rotate. Finally, the brush rollers 512 and the brush bristles 513 at both ends will be driven to rotate in the same direction. One brush bristle 513 sweeps the dust from above the cable, and the other brush bristle 513 sweeps the dust from below the cable, thus ensuring the cleanliness requirement of the cable surface. During the rotation of the brush bristles 513, through the blocking of the abutting rod 618, the brush bristles 513 can generate an inclined deformation. When leaving the abutting rod 618 during the rotation process, the brush bristles 513 will return to their original state. During the process of the brush bristles 513 returning from the inclined deformation to the original state, the dust on the brush bristles 513 will fall due to the influence of vibration, thus avoiding the phenomenon that a large amount of dust stays on the brush bristles 513.

[0033] Combined with the attached Figure 1 As shown in the figure, in order to ensure that the two cable reels 2 are not affected by external dust during use, an upper protection plate 114 and a side protection plate 115 for surrounding the cable reel 2 are provided on the base 111 between the two connecting seats 113.

[0034] When the present invention is specifically implemented, when the distance between the fixed power supply point and the electric shovel is not far, one of the cable reels 2 can be selectively wound up and connected to the electric shovel, and the other cable reel 2 is connected to the fixed power supply without winding up, so as to continuously supply power to the electric shovel. When the distance between the fixed power supply point and the electric shovel is far, the device is moved to the position between the fixed power supply point and the electric shovel. The free end of the cable on one cable reel 2 is connected to the fixed power supply, and the free end of the cable on the other cable reel 2 is connected to the electric shovel. In this way, the length of the cable connected to the electric shovel can be reduced, so as to facilitate the control of the tension of this cable and avoid the dragging phenomenon during the use of this cable. When the cable reel 2 winds and unwinds the cable, the pressing roller 8 can perform a pressing operation on the cable. During the pressing process, the force generated when the pressing roller 8 and the bearing seat 7 slide left and right can be transmitted to the hinge-type swing arm 414, the lower swing rod 413, and the upper swing rod 412, avoiding the phenomenon of single-point force on the first telescopic rod 418, thereby ensuring the stability of the pressing assembly 4 during long-term use; During the process of winding the cable, the cable pulley 212 is driven to rotate, and then the brush rollers 512 and the bristles 513 at both ends are driven to rotate in the same direction, so as to clean the dust on the surface of the cable, ensuring the cleanliness requirements of the cable surface.

[0035] The above describes the present invention and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative efforts without departing from the purpose of the present invention, they shall fall within the protection scope of the present invention.
