DETAILED DESCRIPTION

[0031] The present invention will now be described more fully below with reference to the accompanying drawings, in which currently preferred embodiments of the present invention are shown. However, the present invention may be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and these embodiments fully convey the scope of the present invention to the skilled person.

[0032] A large-scale cable auxiliary docking device for power construction, such as Figure 1-Figure 8As shown, it includes a connecting track 1, a screw rod 2, a slide seat 3, a lower fixing ring 4, an upper fixing ring 41, a fixing structure and a rotating mechanism. The connecting track 1 is provided with two, and the two connecting tracks 1 are rotatably connected on one side close to each other so that the two connecting tracks 1 can be folded with each other, the two connecting tracks 1 are rotatably connected with the screw rod 2, and the threads of the screw rod 2 on both sides are in opposite directions. The connecting track 1 is slidably connected with the slide seat 3, and the slide seat 3 is threadably matched with the screw rod 2 so that the rotation of the screw 2 can drive the slide seat 3 to move, and the tops of the two slide seats 3 are rotatably connected with the lower fixing ring 4, the lower fixing ring 4 is provided with a fixing structure, the upper fixing ring 41 can be fixed on the lower fixing ring 4 through the fixing structure, the lower fixing ring 4 and the upper fixing ring 41 are assembled to form a fixing ring, the fixing ring can rotate on the slide seat 3, and a rotating mechanism is provided between the upper fixing ring 41, the lower fixing ring 4 and the slide seat 3, and the rotating mechanism is used to drive the upper fixing ring 41 and the lower fixing ring 4 to rotate.

[0033] like Figure 5 and Figure 6 As shown, the fixing structure includes a fixing pin 51 and an elastic member 52. The upper parts of the front and rear sides of the lower fixing ring 4 are connected with fixing pins 51. The top of the fixing pin 51 is inclined. When the upper fixing ring 41 is spliced ​​on the lower fixing ring 4, the upper fixing ring 41 can squeeze the fixing pin 51 to move through the inclined position of the top of the fixing pin 51. An elastic member 52 is connected between the fixing pin 51 and the lower fixing ring 4. The elastic member 52 is a connecting spring. The front and rear sides of the upper fixing ring 41 are provided with card slots. When the card slot on the upper fixing ring 41 is aligned with the fixing pin 51, the fixing pin 51 can be inserted into the card slot to fix the upper fixing ring 41 and the lower fixing ring 4 together.

[0034] like Figure 2 and Figure 3 As shown, a plurality of splicing protrusions 21 are evenly spaced on the left side of the right screw rod 2, and a plurality of splicing grooves 22 are evenly spaced on the right side of the left screw rod 2. The number of the splicing protrusions 21 and the splicing grooves 22 are consistent and the positions correspond one to one. When the two screw rods 2 are connected, the splicing protrusions 21 can be stuck in the splicing grooves 22, so that one of the screw rods 2 can drive the other screw rod 2 to rotate together when rotating, so that the two screw rods 2 can rotate synchronously.

[0035] like Figure 7 and Figure 8As shown, the rotating mechanism includes a half worm gear 61 and a worm 62. The upper fixed ring 41 and the lower fixed ring 4 are both connected with the half worm gear 61. When the upper fixed ring 41 and the lower fixed ring 4 are spliced ​​together, the two half worm gears 61 are spliced ​​into a worm gear. The slide seat 3 is rotatably connected with a worm 62, and the worm 62 is meshed with the half worm gear 61, so that the rotation of the worm 62 can drive the half worm gear 61 to rotate, thereby driving the upper fixed ring 41 and the lower fixed ring 4 to rotate.

[0036] When it is necessary to assist in docking the cables 100, the docking device can be used. When in use, the two sections of the connecting rails 1 are first unfolded. When the connecting rails 1 are unfolded, the splicing protrusions 21 on the two screw rods 2 are inserted into the splicing grooves 22, so that the two screw rods 2 are spliced ​​together. Then the two cables can be placed on the lower fixing rings 4 on both sides respectively. After placement, the upper fixing ring 41 is plugged into the lower fixing ring 4. During plugging, the upper fixing ring 41 can squeeze the fixing pin 51 to move outward, and the elastic member 1 52 is compressed. When the slot on the upper fixing ring 41 moves to align with the fixing pin 51, the fixing pin 51 is reset and inserted into the slot under the action of the elastic member 1 52, thereby fixing the upper fixing ring 41 and the lower fixing ring 4 together. The upper fixing ring 41 and the lower fixing ring 4 cooperate to fix the cable, and then the screw 2 can be rotated to drive the slide seats 3 on both sides to approach each other. 3 are close to each other, which can drive the fixing rings on both sides to approach each other, thereby driving the cables on both sides to approach each other, so that the cables on both sides are spliced ​​together. After splicing together, if the corresponding wires on the two cables are not aligned with each other, the worm 62 on one side can be rotated, and the rotation of the worm 62 drives the upper fixing ring 41 and the lower fixing ring 4 to rotate through the half worm gear 61, thereby driving the cable to rotate, adjust the position of the wires on the cable, so that the corresponding wires on the two cables are butted together, and then the butt joint work is performed. In this way, the device can be used to assist in the butt joint of the cables, and during the operation, the cable rotation can be operated more conveniently, so that the corresponding wires on the cables are aligned with each other, and the operation is more convenient. After the splicing is completed, the fixing pin 51 is pulled out of the card slot, and then the upper fixing ring 41 is removed, and then the two connecting rails 1 can be folded together, which is more convenient for storage.

[0037] like Fig. 9As shown, it also includes a supporting mechanism, which includes a connecting seat 71, a swing rod 72, a sliding seat 73, a connecting rod 74, a threaded rod 75, a supporting shaft 76 and an extension shaft 77. The front and rear sides of the sliding seat 3 are connected to the connecting seats 71, and the two connecting seats 71 are rotatably connected to the swing rods 72. The supporting shaft 76 is rotatably connected between the ends of the two swing rods 72. The front and rear sides of the two connecting rails 1 are slidably connected to the sliding seats 73. The sliding seats 73 on both sides are respectively located on the outer sides of the connecting seats 71 on both sides. A connecting rod 74 is connected between the movable seats 73, and a threaded rod 75 is rotatably connected to the side of the sliding seats 3 on both sides that are away from each other. The connecting rod 74 and the threaded rod 75 are threadedly matched so that the rotation of the threaded rod 75 can drive the connecting rod 74 to move, thereby driving the sliding seat 73 to move. An extension shaft 77 is connected to the upper part of the two sliding seats 73. A straight groove is provided on the swing rod 72, and the extension shaft 77 is located in the straight groove, so that the sliding seat 73 can squeeze the straight groove through the extension shaft 77 when sliding, thereby driving the swing rod 72 to swing.

[0038] When placing the cable 100, the supporting shaft 76 can support the position of the cable 100 that is not in the fixed ring, so that the cable 100 is in a parallel state in the fixed ring. When the height of the supporting shaft 76 needs to be adjusted, the threaded rod 75 can be rotated to drive the connecting rod 74 to move left and right through the thread. When the connecting rod 74 moves left and right, it can drive the sliding seat 73 to move left and right. When moving, the sliding seat 73 can squeeze the straight groove through the extension shaft 77 thereon, thereby driving the swing rod 72 to swing, so as to drive the supporting shaft 76 to rise and fall, and adjust the up and down position of the supporting shaft 76 to support cables 100 of different sizes.

[0039] like Fig.10 and Fig.11As shown, it also includes a fixing mechanism, which includes a half-toothed ring 81, a connecting plate 82, an internally threaded sleeve 83, an externally threaded column 84, a transmission gear 85 and a guide rod 86. The lower fixing ring 4 and the upper fixing ring 41 are both rotatably connected with the half-toothed ring 81. When the upper fixing ring 41 and the lower fixing ring 4 are spliced ​​together, the two half-toothed rings 81 constitute a toothed ring. Four connecting plates 82 are evenly spaced and connected between the outer sides of the lower fixing ring 4 and the upper fixing ring 41. Four internally threaded sleeves 83 are evenly spaced and rotatably connected on the lower fixing ring 4 and the upper fixing ring 41. The connecting plate 82 is located at the upper part of the internal threaded sleeve 83, and an external threaded column 84 is connected to the internal threaded sleeve 83 through a thread. The lower part of the internal threaded sleeve 83 is connected to a transmission gear 85, and the transmission gear 85 is meshed with the half-toothed ring 81, so that when one of the internal threaded sleeves 83 rotates, it can drive the other internal threaded sleeves 83 to rotate together through the transmission of the transmission gear 85 and the half-toothed ring 81. A guide rod 86 is connected in the middle of the connecting plate 82, and the guide rod 86 is slidably connected to the external threaded column 84, so that the external threaded column 84 can be guided by the guide rod 86 when moving.

[0040] After the cable is placed, one of the internal threaded sleeves 83 can be operated to rotate. When rotating, one of the internal threaded sleeves 83 can drive the other internal threaded sleeves 83 to rotate together through the transmission between the half gear ring 81 and the transmission gear 85. When the internal threaded sleeve 83 rotates, it can drive the external threaded column 84 to move toward the cable, thereby driving the friction pad 9 to move together, so that the friction pad 9 presses against the cable to fix the cable. The cable can be fixed by moving the external threaded column 84, and cables of different thicknesses can be fixed, with a wider overall adaptability.

[0041] like Fig.12 As shown, a friction pad 9 is also included. The sides of the four external threaded columns 84 that are close to each other are connected to the friction pad 9 through a ball joint connection. When the external threaded column 84 moves to press against the cable, the friction pad 9 can increase the friction between the cable.

[0042] like Fig.13 As shown, it also includes a threaded rod 10. The two connecting rails 1 are connected to each other on one side away from each other by threads. The threaded rod 10 can move downward through the threads and be inserted into the ground when rotating, thereby fixing the connecting rails 1 at the ground position.

[0043] like Fig.13 and Fig.14As shown, a shielding mechanism is also included, which includes a splicing block 11, a folding material blocking cloth 12 and a magnet 13. The lower part of the side where the two slides 3 are close to each other is slidably connected with a splicing block 11, and a folding material blocking cloth 12 is connected between the splicing block 11 and the slide 3. The side where the two splicing blocks 11 are close to each other is embedded with a magnet 13. When the two splicing blocks 11 are spliced ​​together, the two magnets 13 are magnetically attracted to each other, thereby fixing the two splicing blocks 11 together.

[0044] When using the device to connect cables, the two splicing blocks 11 can be spliced ​​together through the magnet 13, so that the folded material blocking cloth 12 can be unfolded. During the splicing process, the parts in the splicing process can be blocked to prevent parts from falling onto the connecting track 1.

[0045] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
