Description

Technical Field

[0001] The utility model relates to the technical field of electric wire tapping, in particular to a tapping device for power transmission and distribution cables. Background Art

[0002] Transmission lines are structures used to carry and transmit electricity. Generally, in order to adapt to the bearing capacity of the wires, a specific length of wires will be cut. However, in order to transmit electricity, a special tapping device will be used to connect adjacent wires: 1. The existing tapping device generally uses bolts to tighten the joints downward. In the publication number CN221057978U, the joints are fixed by pressing down. However, the quadrilateral formed by the pressed transmission rod is not firm, and it is an overall pressing fixation, which is not convenient for repairing a single joint. Therefore, it needs to be improved; 2. The tapping device is generally placed indoors or outdoors. After long-term use, the joints will be contaminated with dust due to static electricity, which is not conducive to the maintenance of the tapping device. Therefore, we propose a tapping device for power transmission and distribution cables. Utility Model Content

[0017] 1. By setting up a fixed structure, when the rotating screw on the fixed structure rotates and moves up and down, it can drive the mobile pressing frame to move, and the mobile pressing frame moves down to press and fix the joint. It has independence and will not affect the maintenance of the joint next door. The rotating screw is threadedly connected with the threaded sleeve and does not contact the wire, which can prevent the swinging wire from causing thread slippage, making the joint connection stable.

[0018] 2. By setting up a protective structure, the protective cover on the protective structure can protect the internal fixed structure, the mounting column and the joint. The clamping rod on the rotating plate that is movably connected to the mounting ear is clamped with the fixed hole, so that the protective structure can be connected to the connecting plate, which can reduce dust adhesion on the tapping device and facilitate subsequent maintenance.

[0027] See also Figure 1-4 , the utility model provides a technical solution:

[0028] A tapping device for power transmission and distribution cables comprises a connecting plate 1, wherein the left and right lower ends of the connecting plate 1 are fixedly connected to mounting plates 2, fixing bolts 3 are inserted and fixedly connected to the two sets of mounting plates 2, a plurality of mounting columns 4 are fixedly connected to the middle of the upper end of the connecting plate 1 at equal distances, a plurality of air holes 5 are opened at equal distances at the front and rear upper ends of the connecting plate 1, fixing holes 6 are opened at the middle of the left and right ends of the connecting plate 1, a plurality of fixing structures 7 are fixedly connected to the middle of the upper end of the connecting plate 1 at equal distances, and a protective structure 8 is fixedly connected to the upper end of the connecting plate 1.

[0029] In this embodiment, the fixed structure 7 includes a support frame 9 and a movable pressing frame 10. A threaded sleeve 11 is fixedly connected to the middle part of the lower end of the support frame 9. A through slot 12 is opened at the left and right ends of the support frame 9. A rotating screw 13 is movably inserted and movably clamped in the middle part of the upper end of the movable pressing frame 10. Two groups of limiting plates 14 are inserted and fixedly connected to the upper part of the rotating screw 13. An insertion hole 15 is opened in the middle part of the lower end of the movable pressing frame 10. The movable pressing frame 10 passes through the through slot 12, and the rotating screw 13 is inserted and threadedly clamped with the threaded sleeve 11. The movable pressing frame 10 passes through the through slot 12, and the rotating screw 13 is inserted and threadedly clamped with the threaded sleeve 11.

[0030] Through the above scheme: after the joint is wrapped around the outer surface of the mounting column 4, the rotating screw 13 is rotated, and the movable pressing frame 10 movably connected to the rotating screw 13 is inserted down, and the lower structure will press and tighten the joint to complete the task of stabilizing the joint. At the same time, the left and right parts of the movable pressing frame 10 are movably engaged with the through slot 12, and no rotational swing occurs during rotation. The rotating screw 13 is threadedly engaged with the threaded sleeve 11 on the support frame 9, and the swinging of the lower wire will not affect the connection of the rotating screw 13, thereby ensuring the stability of the joint.

[0031] In this embodiment, the protective structure 8 includes a protective cover 81, and a plurality of rectangular grooves 82 are evenly spaced at the lower front end and the lower rear end of the protective cover 81. The left and right ends of the protective cover 81 are fixedly connected with mounting ears 83. The two groups of mounting ears 83 are movably connected with rotating plates 84 through rotating shafts. The front and rear ends of the two groups of rotating plates 84 close to the protective cover 81 are fixedly connected with connecting springs 85. The middle of the lower end of the two groups of rotating plates 84 close to the protective cover 81 is fixedly connected with a clamping rod 86. The connecting spring 85 is fixedly connected to the protective cover 81, and the clamping rod 86 is clamped with the fixing hole 6.

[0032] Through the above scheme: the rotating plate 84 movably connected to the mounting ears 83 on the left and right ends of the protective cover 81 through the rotating shaft is rotated outward, and then the protective cover 81 is sleeved on the outside of the connecting plate 1, and the external force applied to the rotating plate 84 is removed. Under the reaction force of the connecting spring 85, the clamping rod 86 moves inward and clamps with the fixing hole 6 opened on the connecting plate 1, completing the installation of the protective structure 8. Otherwise, it is disassembled. The operation is simple but can protect the internal structure.

[0033] It should be noted that the utility model is a tapping device for power transmission and distribution cables. During use, the tapping device is first fixed in position using the mounting plate 2 and the fixing bolts 3, and then the mounting column 4 is used to wrap the joint around the surface of the mounting column 4 to ensure that the two connected wires can be connected, and then the fixing structure 7 is used to twist the rotating screw 13, and the rotating screw 13 is rotated and moved downward. Driven by the limiting plate 14, the mobile pressing frame 10 moves downward together, and after the insertion hole 15 at the lower end of the mobile pressing frame 10 passes through the mounting column 4, the lower structure presses and fixes the joint, completing the stabilization of the position of the joint, and the left and right ends of the mobile pressing frame 10 are connected to the The insertion and locking of the slot 12 can prevent rotation during movement, and the rotating screw 13 does not contact the joint, which can increase stability. Otherwise, the thread slips and becomes loose. After the joint is connected, use the protective structure 8 to rotate the rotating plates 84 at the left and right ends of the protective cover 81 on the protective structure 8 outward, and put the protective cover 81 on the outside of the connecting plate 1, and then reduce the external force applied to the rotating plate 84. Driven by the connecting spring 85, the rotating plate 84 can be reset, and at the same time, the locking rod 86 can be driven to be locked and fixed with the fixing hole 6. The operation is simple, and the fixing structure 7 and the joint can be protected, dust accumulation can be reduced, and later maintenance is convenient.
