Because the overhead power lines may be close to trees, buildings, tunnels, rivers, etc., or the safety distance between overhead power lines and other weak current (communication, optical fiber, broadcasting lines) lines is difficult to ensure, this will cause a series of safety problems. In view of the above-mentioned safety hazards caused by the exposure of overhead power lines, it is necessary to fix an insulating sheath structure on the outer sheath of the exposed overhead power lines to achieve insulation protection of high-voltage cables.

[0003] Among them, for the insulating sheath, it generally adopts a snap-on structure, and the snap-on insulating sheath includes a main body, a buckle portion is provided on one side edge of the main body, and a buckle groove portion is provided on the other side edge of the main body; when the snap-on insulating sheath is installed on the overhead power line, the main body of the insulating sheath is curled and wrapped around the outer periphery of the overhead power line, and the buckle portion of the insulating sheath is buckled into the buckle groove portion to fix the insulating sheath.

[0005] When the above-mentioned device for packaging the sheath of the bare wire is working, the insulating sheath is inserted into the wire rolling frame, and a section of the insulating sheath is put on the bare wire with the groove and the protrusion facing downward, and the wire section with the sheath put on is placed under the pressure wheel and between the pulleys, and the lock of the upper cover is locked. The device is suspended on the front section of the bare wire without the insulating sheath installed, and the rope inserted in the tow hook is pulled as the insulating sheath is installed. Due to the action of the pulley, the device maintains horizontal movement on the wire and is easy to buckle with the insulating sheath. A buckling device is used, and a plurality of pressure wheels are arranged in the buckling device. The insulating sheath is buckled on the outside of the wire through the action of the pressure wheels.

[0071] In the process of adaptively adjusting the left and right positions of the lower end left power wheel 72 and the lower end right power wheel 73, the staff only needs to loosen the corresponding locking screws first, and then move the lower end left power wheel 72 or the lower end right power wheel 73 along the corresponding anti-rotation key structure; after the lower end left power wheel 72 or the lower end right power wheel 73 is moved left and right and adjusted to the right position, tighten the corresponding locking screws to lock the lower end left power wheel 72 or the lower end right power wheel 73 in the desired position.

[0072] It should be pointed out that, in the process of conveying the insulating sheath 101, the upper left power wheel 77 is aligned with the lower left power wheel 72 and together form a conveying roller wheel set structure, and the upper right power wheel 78 is aligned with the lower right power wheel 73 and together form a conveying roller wheel set structure. Since the left wheel axle 761 and the right wheel axle 762 are respectively locked and fixed to the movable swing arm 75 by corresponding locks 751, in the process of adaptively adjusting the left and right positions of the lower left power wheel 72 and the lower right power wheel 73, the staff can also adaptively adjust the left and right positions of the upper left power wheel 77 and the upper right power wheel 78; specifically, when adjusting, it is only necessary to loosen the lock 751 and adaptively move the position of the left wheel axle 761 or the right wheel axle 762 along the left and right directions, and after the left wheel axle 761 or the right wheel axle 762 is adjusted to the right and left, the lock 751 can be locked.

[0073] Embodiment 4, as Figures 1 to 6 As shown, the difference between this fourth embodiment and the first embodiment is that the snap-fit ​​assembly 2 includes a left snap-fit ​​wheel group and a right snap-fit ​​wheel group located at the right end of the left snap-fit ​​wheel group, and a snap-fit ​​channel 21 is formed between the left snap-fit ​​wheel group and the right snap-fit ​​wheel group for the insulating sheath 101 to pass from back to front, and the width of the snap-fit ​​channel 21 gradually decreases from back to front.

[0074] The left side engaging wheel assembly includes a plurality of left side engaging wheels 22 which are arranged in sequence and rotatably mounted on the main body base 1 , and the right side engaging wheel assembly includes a plurality of right side engaging wheels 23 which are arranged in sequence and rotatably mounted on the main body base 1 .

[0075] During the process of the buckling assembly 2 realizing the buckling of the insulating sheath 101, the insulating sheath 101 passes through the buckling channel 21 from back to front under the traction drive of the front power wheel group 6 and the rear power wheel group 7. Since the buckling channel 21 gradually narrows from back to front, during this process, the left buckling wheel group presses the insulating sheath 101 toward the right side, and the right buckling group presses the insulating sheath 101 toward the left side, thereby making the buckle portion of the insulating sheath 101 buckle with the buckle groove portion.

[0076] Embodiment 5, as Figures 1 to 6 As shown, the difference between the fifth embodiment and the fourth embodiment is that the main body base 1 is equipped with a lifting and adjusting bracket 24, the upper end of which extends to above the left-side snap-fit ​​wheel group and the right-side snap-fit ​​wheel group, and the upper end of the lifting and adjusting bracket 24 is rotatably installed with a plurality of auxiliary pressure wheels 25 arranged in sequence from front to back.

[0077] When the insulating sheath 101 passes through the buckling channel 21 , the auxiliary pressing wheels 25 can press the insulating sheath 101 downward to ensure that the buckling position of the insulating sheath 101 passes through the buckling channel 21 accurately, thereby ensuring the stability and reliability of the buckling operation.

[0078] In addition, the auxiliary pressing wheel 25 is installed on the upper end of the lifting and adjusting bracket 24 , and the lifting and adjusting bracket 24 can make the height of the auxiliary pressing wheel 25 adaptively adjusted according to the size specifications of the insulating sheath 101 .

[0079] For the left guide wheel 24 and the right guide wheel 25 of the fifth embodiment, they can adaptively adjust their positions to ensure that the insulating sheath 101 accurately enters the snap-fitting channel 21 of the snap-fitting assembly 2 through the cooperation of the left guide wheel 24 and the right guide wheel 25, thereby ensuring that the insulating sheath 101 can be stably snap-fitted.

[0080] Embodiment six, as Fig.11 As shown, the difference between this embodiment six and embodiment one is that the guide wheel assembly 4 includes a guide wheel bracket 41 fastened to the main base 1, and the guide wheel bracket 41 is equipped with a plurality of guide wheel groups 42 arranged in sequence from front to back, and each guide wheel group 42 includes two sheath guide wheels 421 whose intermediate spacing can be adaptively adjusted according to the size specifications of the insulating sheath 101.

[0081] Embodiment seven, as Figure 7 and Figure 8 As shown, the difference between the seventh embodiment and the first embodiment is that the swing arm opening and closing driving mechanism 79 includes a base connecting shaft 791 installed on the main body base 1 and a swing arm connecting shaft 792 arranged at the lower end of the movable swing arm 75, and the base connecting seat and the swing arm connecting shaft 792 are arranged in parallel and at intervals.

[0082] Among them, the first connecting rod 793 and the second connecting rod 794 are installed between the base connecting shaft 791 and the swing arm connecting shaft 792. The fixed end of the first connecting rod 793 is pivoted to the base connecting shaft 791, the fixed end of the second connecting rod 794 is pivoted to the swing arm connecting shaft 792, and the free end of the first connecting rod 793 is hinged to the free end of the second connecting rod 794.

[0083] In addition, an opening and closing operating handle 795 is fastened to the first link 793 .

[0084] It should be noted that when the opening and closing operating handle 795 swings to the open position, the opening and closing operating handle 795 pulls the free end of the first connecting rod 793 to swing downward, and pulls the lower end of the movable swing arm 75 to swing downward through the second connecting rod 794. During this process, the upper end of the movable swing arm 75 swings upward to the open state position. When the opening and closing operating handle 795 swings to the closed position, the opening and closing operating handle 795 pulls the free end of the first connecting rod 793 to swing upward, and pushes the lower end of the movable swing arm 75 to swing upward through the second connecting rod 794. During this process, the upper end of the movable swing arm 75 swings downward to the closed state position.

[0085] Embodiment eight, as Figures 12 to 15 As shown, the difference between this embodiment eight and embodiment one is that: the storage tray bottom cover 931 is screwed and fastened with at least two coil positioning rods 933 which protrude and extend toward the sides of the storage tray surface cover 932 respectively, and each coil positioning rod 933 is respectively provided with a plurality of locking grooves 9331 which are arranged in sequence and spaced apart along the axial direction.

[0086] The storage tray cover 932 is provided with cover positioning holes corresponding to each coil positioning rod 933 , and elastic locking members 934 are installed at the positions of each cover positioning hole on the outer side of the storage tray cover 932 .

[0087] It should be noted that when the storage tray cover 932 is in a closed state, each coil positioning rod 933 passes through the corresponding cover positioning hole, and the elastic locking member 934 is locked in one of the locking grooves 9331 of the coil positioning rod 933. Among them, this embodiment eight can make the locking position of the storage tray cover 932 adapt to the width size of the insulating sheath 101, so as to ensure that the sheath storage tray 93 can stably load and place the insulating sheath coil 92.

[0088] It should be explained that when the insulating sheath roll 92 is placed, the insulating sheath roll 92 is located outside the roll positioning rod 933 , and the roll positioning rod 933 can position the insulating sheath roll 92 .

[0089] Embodiment 9, as Figures 13 to 15As shown, the difference between this ninth embodiment and the first embodiment is that a damping adjustment mechanism 97 is installed on the loading bracket 91 corresponding to the storage tray shaft 95, and the damping adjustment mechanism 97 includes a fixed block 971 which is fastened to the loading bracket 91, and an axial hole is opened on the fixed block 971 corresponding to the storage tray shaft 95, and the end of the storage tray shaft 95 is rotatably embedded in the axial hole of the fixed block 971.

[0090] Among them, the upper surface of the fixed block 971 is provided with an adjustment hole 9711 connected to the shaft hole, and the adjustment hole 9711 is embedded with a pressure block 972, an adjustment spring 973, and a handle screw 974 arranged in sequence from bottom to top. The lower end of the pressure block 972 abuts against the storage tray shaft 95, the lower end of the adjustment spring 973 abuts against the upper end of the pressure block 972, the handle screw 974 is screwed into the adjustment hole 9711, and the upper end of the adjustment spring 973 abuts against the handle screw 974.

[0091] During the process of automatic packaging of the insulating sheath 101 by the sheath guiding and snap-fitting assembly, the traction force generated by the automatic sheath conveying component enables the insulating sheath roll 92 to continuously release the insulating sheath 101. The damping adjustment mechanism 97 of the ninth embodiment can adaptively adjust the resistance of the sheath storage tray 93 during rotation to ensure that the insulating sheath 101 can be released stably and continuously.

[0092] Among them, when adjusting the rotation resistance of the sheath storage tray 93, it is only necessary to manually loosen or tighten the handle screw 974 so that the handle screw 974 and the adjustment hole 9711 of the fixed block 971 can move vertically; when the handle screw 974 is tightened, the adjusting spring 973 is further compressed, thereby increasing the pressing force of the pressure block 972 on the storage tray rotating shaft 95, thereby increasing the friction between the pressure block 972 and the storage tray rotating shaft 95, thereby increasing the resistance; when the handle screw 974 is rotated, the adjusting spring 973 is relaxed, thereby reducing the pressing force of the pressure block 972 on the storage tray rotating shaft 95, thereby reducing the friction between the pressure block 972 and the storage tray rotating shaft 95, thereby reducing the resistance.

[0093] Embodiment ten, as Fig.14 and Fig.15 As shown, the difference between this embodiment ten and embodiment one is that an auxiliary spring 981 and a top ring 982 are mounted on the periphery of the storage tray shaft 95 between the bottom cover sleeve 9311 and the bracket bearing seat 94, one end of the auxiliary spring 981 abuts against the bracket bearing seat 94, and the other end of the auxiliary spring 981 abuts against the top ring 982, and the top ring 982 is in contact with the bottom cover bearing.

[0094] When the sheath storage tray 93 loaded with the insulating sheath coil 92 is placed on the storage tray rotating shaft 95, the storage tray rotating shaft 95 limits the sheath storage tray 93 through the rotating shaft anti-drop lock 96 at its end position to prevent the sheath storage tray 93 from being stripped from the storage tray rotating shaft 95. After the sheath storage tray 93 loaded with the insulating sheath coil 92 is placed, the elastic force of the auxiliary spring 981 makes the top ring 982 elastically support the bottom cover bearing, so that the bottom cover bearing abuts against the position of the rotating shaft anti-drop lock 96 limited to the storage tray rotating shaft 95. The elastic supporting structure composed of the auxiliary spring 981 and the top ring 982 can make the storage tray rotating shaft 95 suitable for sheath storage trays 93 of different widths. In the process of the insulating sheath 101 being pulled out, the above-mentioned elastic supporting structure can effectively prevent the axial displacement of the sheath storage tray 93 to improve the stability and reliability of loading.

For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The content of this specification should not be understood as limiting the present invention.
