DETAILED DESCRIPTION

[0023] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figure 1 - Figure 6The power supply line construction tool shown in the figure includes a main frame 1 and a sub-frame 2, the main frame 1 and the sub-frame 2 are fixedly connected to the same side with a side frame 8, a slot changing box 9 is fixedly connected between the two side frames 8, the slot changing box 9 is provided with a slot changing mechanism and a jacking mechanism driven by the slot changing mechanism, the slot changing mechanism includes a moving plate 11 arranged inside the slot changing box 9, the surface of the moving plate 11 is provided with a slot 13, a slot 2 14 and a slot 3 15, the slot 13, the slot 2 14 and the slot 3 15 are all provided with a bevel 16, the slot 3 15 is provided with a matching card inside Groove 17. During the wire-laying construction process, the drone will first put the guide rope into the first pulley close to the guide plate 4, and then the drone will drive the guide rope to descend, so that the jacking block 20, under the action of the spring 22 and its own inclined surface, will send the guide rope to the second pulley, and then send the second guide rope to the first pulley and press it down again. The two jacking blocks 20 will simultaneously send the two guide ropes to the next pulley, so that the simple operation of the drone rising and falling can realize the automatic groove changing function of the cable on the multi-wheel pulley.

[0025] The jacking mechanism includes three jacking rods 19 slidably connected to the inside of the slot changing box 9, the top ends of the three jacking rods 19 are respectively fixedly connected to two jacking blocks 20 and a jacking plate 21, the bottom ends of the jacking rods 19 connected to the jacking blocks 20 are fixedly connected to an inclined block 23, and the bottom ends of the jacking rods 19 connected to the jacking plate 21 are fixedly connected to a clamping block 24. When the cable moves to the third pulley, the jacking plate 21 will be squeezed, and the jacking plate 21 will be restricted and fixed by the slot three 15, and the pressure plate 27 is used to drive the first two jacking blocks 20 to descend, thereby preventing the jacking blocks 20 from affecting the cable stringing work, and preventing the jacking blocks 20 from rubbing against the cables, causing damage to the cable sheath, and affecting the stable operation of the power system.

[0026] The lifting mechanism specifically includes an elastic member 10 fixedly connected to one end of the moving plate 11, and the end of the elastic member 10 away from the moving plate 11 is fixedly connected to the inner wall of the slot changing box 9. The elastic member 10 can reset the moving plate 11 and provide a stronger elastic force for the two lifting blocks 20 to ensure that the cables can be normally switched to other pulleys. The end of the moving plate 11 opposite to the elastic member 10 is fixedly connected with a limiting rod 12, and the limiting rod 12 is slidably connected to the inner wall of the slot changing box 9. The limiting rod 12 can prevent the moving plate 11 from falling off, causing the moving plate 11 to lose its function of fixing the lifting plate 21.

[0027] The lifting mechanism specifically includes three lifting holes 18 arranged at the top of the slot changing box 9, three lifting rods 19 are in a sliding connection with the three lifting holes 18, and the three lifting rods 19 are located on the outer surface of the slot changing box 9 and are provided with springs 22. The spring 22 is located between the lifting block 20 or the lifting plate 21 and the slot changing box 9. The spring 22 can provide an elastic force for the lifting block 20 after compression, driving the lifting block 20 to bounce the cable away so that the cable can enter the next pulley, thereby realizing the function of automatic slot changing.

[0028] The lifting rod 19 connected to the lifting block 20 is fixedly connected to a connecting plate 25 on the surface inside the slot changing box 9, and a through hole 26 is provided on one side of the connecting plate 25. The lifting rod 19 connected to the lifting plate 21 is in a penetrating state with the connecting plate 25 through the through hole 26. Since the lifting rod 19 connected to the lifting plate 21 and the connecting plate 25 are in a penetrating state, when the lifting block 20 is pressed down, the lifting plate 21 will not be locked, thereby ensuring that the first two lifting blocks 20 can be lifted normally, and the cable can also automatically change slots.

[0029] The lifting rod 19 connected to the lifting plate 21 is located on the outer surface of the inside of the slot changing box 9 and is fixedly connected with a pressure plate 27. The pressure plate 27 is located above the connecting plate 25. When the lifting plate 21 is pressed down, the pressure plate 27 will drive the connecting plate 25 to descend, thereby causing the first two lifting blocks 20 to descend, thereby avoiding friction between the lifting blocks 20 and the cables, which would affect the cable stringing work.

[0030] A mounting plate 3 is fixedly installed on the top of the main frame 1 and the sub-frame 2, and a guide plate 4 is fixedly connected to the side of the sub-frame 2 away from the main frame 1. The guide plate 4 can increase the entrance space for the guide rope to enter the pulley block 7, making the entry of the guide rope more convenient, thereby further increasing the placement efficiency of the guide rope. An anti-slip mechanism 5 is arranged inside the sub-frame 2, and the anti-slip mechanism 5 is located above the guide plate 4, and the anti-slip mechanism 5 can prevent the guide rope from falling off after entering the pulley block 7.

[0031] The main frame 1 and the auxiliary frame 2 are internally fixedly connected with an axle 6, and the outer surface of the axle 6 is rotatably connected with a pulley block 7. The groove on the surface of the pulley block 7 is consistent with the height of the lifting plate 21. The lifting plate 21 is consistent with the height of the groove of the pulley in the locked state, and is higher than the height of the groove in the unlocked state, ensuring that after the cable enters the third pulley, other cables will not be pushed open, thereby ensuring the normal operation of the slot changing mechanism.

[0032] The two inclined blocks 23 cooperate with slot one 13 and slot two 14 respectively. The inclined block 23 is parallel to the bevel 16 and cooperates with each other. The cooperation between the inclined block 23 and the bevel 16 will drive the movable plate 11 to move, so that the elastic member 10 provides a stronger elastic force, so that the cable can be smoothly replaced. The card block 24 cooperates with slot three 15. When the card block 24 cooperates with slot three 15, it is restricted by the matching card slot 17. The matching card slot 17 in slot three 15 cooperates with the card block 24 to lock the entire jacking mechanism, thereby preventing the jacking mechanism from rubbing against the cable, damaging the cable sheath, and affecting the normal operation of the power system.

[0033] Working principle: First, it is necessary to use a drone to lift the guide rope to a high altitude, then place the guide rope on the guide plate 4, and then move along the direction of the guide plate 4. After the anti-slip mechanism 5 is pushed open, it can enter the pulley block 7, and the anti-slip mechanism 5 will also limit the guide rope to ensure that the guide rope will only fall into the first pulley, and then the drone can be operated to pull the cable, and slowly descend during the pulling process. When the cable reaches the pulley block 7, the drone can be raised, and the jacking block 20 will bounce up under the action of the elastic member 10 and the spring 22 without the pressure applied by the drone, and use its own inclined surface to move the cable to the second pulley, and then pull the second cable until the first cable enters the third pulley, which will drive the jacking plate 21 to lock the jacking mechanism to prevent the cable from rubbing against the jacking mechanism and damaging the cable sheath. At this time, the preliminary cable stringing work is completed. In this stringing process, the simple up and down movement of the drone can enable the cable to complete the slot changing work, thereby improving the efficiency of the cable stringing construction.
