Description

Technical Field

[0001] This utility model relates to a wire breaking device, specifically a high-altitude wire breaking device. Background Technology

[0002] The wire cutting device is a special operating tool commonly used in overhead contact line suspension maintenance or power line emergency repair operations. This wire cutting device can be used for live work, and its main function is to cut power cables.

[0003] Existing wire cutting devices are typically wire cutters, which have short handles. When cutting high-position power cables, workers must either climb onto a high work platform or use ropes to tie the wire cutter to a long pole before cutting. However, working on a work platform poses a risk of falls, compromising safety. When tying the wire cutter to a pole, it is often not securely fastened, allowing it to fall and potentially damage workers, further compromising safety. Furthermore, the tied wire cutter is usually parallel to the pole, making it impossible to adjust the angle between them according to the specific situation, hindering operation and significantly reducing efficiency. Summary of the Invention

[0004] To address the aforementioned shortcomings in existing technologies, this utility model aims to provide a high-altitude wire breaking device to improve construction safety and efficiency.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a high-altitude wire cutting device, comprising a telescopic insulating rod mechanism, a quick-release connecting component disposed on the top of the telescopic insulating rod mechanism, and a wire cutting mechanism disposed on the quick-release connecting component via an adjustable connecting seat, wherein the adjustable connecting seat can adjust the included angle between the wire cutting mechanism and the telescopic insulating rod mechanism.

[0006] As a limitation of this utility model, the adjustable connecting seat includes a first connecting member fixed to the top of the quick-release connecting component, a plurality of first protrusions arranged in a circular array and fixed at intervals on one side of the first connecting member, a plurality of second protrusions arranged in a circular array and inserted between the plurality of first protrusions, a second connecting member fixed on the plurality of second protrusions, a fastening bolt detachably connected to the first connecting member and the second connecting member and passing through the first connecting member and the second connecting member, and a fastening washer sleeved on the screw of the fastening bolt near the end of the nut, wherein the end of the second connecting member is detachably connected to the wire cutting mechanism.

[0007] As a further limitation of this utility model, the wire cutter mechanism is a wireless remote-controlled rechargeable wire cutter.

[0008] As a further limitation of this utility model, the outer surface of the telescopic insulating rod mechanism is coated with reflective paint.

[0009] As a further limitation of this utility model, the fastening bolt is a wing bolt.

[0010] As another limitation of this utility model, the telescopic insulating rod mechanism includes at least two insulating rods that are sequentially sleeved together, and a locking mechanism is provided between each pair of adjacent insulating rods to lock the adjacent insulating rods together.

[0011] As a further limitation of this utility model, the locking mechanism includes an open clamp with a transverse dividing slit. The portion of the open clamp located below the transverse dividing slit is fixed to the upper end of the lower insulating rod in two adjacent insulating rod sections, and the portion of the open clamp located above the transverse dividing slit is mounted on the upper insulating rod in two adjacent insulating rod sections by a locking member.

[0012] By adopting the above-mentioned technical solution, the beneficial effects achieved by this utility model compared with the prior art are as follows: (1) This utility model adopts a structural form combining a telescopic insulating rod mechanism, a quick-release connecting component, an adjustable connecting seat, and a wire cutter mechanism. The quick-release connecting component is firmly set on the telescopic insulating rod mechanism, and the wire cutter mechanism can be firmly set on the quick-release connecting component through the adjustable connecting seat. In use, after adjusting the telescopic insulating rod mechanism to the required length according to actual needs, the lower end of the telescopic insulating rod mechanism can be held to perform power cable cutting operations. Furthermore, the wire cutter mechanism is firmly set on the telescopic insulating rod mechanism, preventing it from falling and effectively improving construction safety. In addition, the adjustable connecting seat can adjust the angle between the wire cutter mechanism and the telescopic insulating rod mechanism. In use, the angle between the wire cutter mechanism and the telescopic insulating rod mechanism can be adjusted adaptively according to the actual construction situation, making it easier for construction personnel to cut power cables and improving their work efficiency.

[0013] (2) The adjustable connecting seat in this utility model has an ingenious structural design. The adjustable connecting seat includes a first connecting piece, multiple first protrusions, multiple second protrusions, a second connecting piece, fastening bolts and fastening washers. The end of the second connecting piece is detachably connected to the wire cutter mechanism. By adjusting the included angle between the second connecting piece and the first connecting piece, the included angle between the wire cutter mechanism and the telescopic insulating rod mechanism can be adjusted. When in use, remove the fastening bolts and fastening washers, adjust the angle between the first connecting piece and the second connecting piece to a suitable position, and insert the multiple second protrusions into the positions between the multiple first protrusions. Then install the fastening bolts and tighten them. At this time, the second connecting piece can be firmly fixed on the first connecting piece, and the multiple second protrusions are inserted into the positions between the multiple first protrusions. It is not easy for the first connecting piece and the second connecting piece to rotate, which makes the connection between the first connecting piece and the second connecting piece more secure and can improve the reliability of the adjustable connecting seat structure.

[0014] (3) The wire cutting mechanism of this utility model adopts a wireless remote control rechargeable wire cutter, which can cut power cables through remote control. The wireless remote control rechargeable wire cutter works in conjunction with the telescopic insulating rod mechanism, so that people can cut power cables at high altitudes while standing on the ground. It is safe to use and very convenient to operate.

[0015] (4) The outer surface of the telescopic insulating rod mechanism in this utility model is coated with reflective paint, which can improve the visibility of this utility model in the case of insufficient light and improve the safety of using this utility model.

[0016] (5) The fastening bolts in this utility model are wing bolts, which can improve the convenience and practicality of this utility model.

[0017] (6) In this utility model, after the telescopic insulating rod mechanism is adjusted to the appropriate length, the locking mechanism can securely position the telescopic insulating rod mechanism at the required length position, making it safe and reliable to use.

[0018] In summary, this utility model has a reasonable structure, is convenient to use, and is highly practical. Firstly, the wire-cutting mechanism is securely mounted on the telescopic insulating rod mechanism, preventing it from falling. During use, after adjusting the telescopic insulating rod mechanism to the required length, the lower end can be held to cut the power cable, eliminating the need for climbing and improving safety. Secondly, the adjustable connecting seat allows for adjustment of the angle between the wire-cutting mechanism and the telescopic insulating rod mechanism. This angle can be adaptively adjusted according to the actual construction situation, making it easier for workers to cut the power cable and improving work efficiency. This utility model is suitable for use in power construction. Attached Figure Description

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0022] An embodiment of a high-altitude wire breaking device like Figure 1 As shown, this embodiment includes a telescopic insulating rod mechanism 1, a quick-release connecting member 3 disposed on the top of the telescopic insulating rod mechanism 1, and a wire cutter mechanism 10 disposed on the quick-release connecting member 3 via an adjustable connecting seat, wherein the adjustable connecting seat can adjust the included angle between the wire cutter mechanism 10 and the telescopic insulating rod mechanism 1.

[0023] like Figure 2As shown, the telescopic insulating rod mechanism 1 includes at least two insulating rods nested together. A locking mechanism 2 is provided between each pair of adjacent insulating rods to lock them together. The locking mechanism 2 includes an open clamp 21 with a transverse dividing slit 22. The portion of the open clamp 21 located below the transverse dividing slit 22 is fixed to the upper end of the lower insulating rod in the adjacent two insulating rods. The portion of the open clamp 21 located above the transverse dividing slit 22 is secured to the upper insulating rod in the adjacent two insulating rods via a locking member. The insulating rods can be made of insulating materials such as epoxy resin or a composite material of glass fiber and epoxy resin. When the locking member is in the unlocked state, a gap exists between the portion of the open clamp located above the transverse dividing slit 22 and the upper insulating rod in the adjacent two insulating rods, allowing the adjacent insulating rods to slide relative to each other, thus enabling telescopic adjustment. When the locking member is in the locked state, the adjacent insulating rods are locked together. Furthermore, the locking component includes a threaded post 23 that passes through and is threadedly connected to the two ear plates 28 in the open clamp 21, a connecting ring 24 fixed to the end of the threaded post 23, an eccentric handle 26 hinged to the connecting ring 24 via a hinge shaft, and an adjusting nut 25 threadedly connected to the end of the threaded post 23 away from the connecting ring 24. A rubber pad 27 is fitted on the end of the threaded post 23 near the connecting ring 24. When the eccentric handle 26 is in the locked state, it can cause the portion of the open clamp 21 located above the transverse dividing seam 22 to clamp the upper insulating rod of the two adjacent insulating rods inward so that the two adjacent insulating rods are fixed together. When the eccentric handle 26 is in the unlocked state, it can cause the portion of the open clamp 21 located above the transverse dividing seam 22 to release the upper insulating rod of the two adjacent insulating rods outward so that the two adjacent insulating rods can slide relative to each other.Specifically, the hinge shaft on the eccentric handle 26 is eccentrically positioned, and the distance from the outer periphery of the part of the eccentric handle 26 that contacts the connecting ring 24 to the rotation center of the eccentric handle 26 gradually increases. Here, the position where the distance from the outer periphery of the part of the eccentric handle 26 that contacts the connecting ring 24 to the rotation center is minimum is defined as the low position of the eccentric handle 26, and the position where the distance from the outer periphery of the part of the eccentric handle 26 that contacts the connecting ring 24 to the rotation center is maximum is defined as the high position of the eccentric handle 26. When the eccentric handle 26 is in the low position, the portion of the open clamp located above the transverse dividing seam 22 is not... The eccentric handle 26 applies an inward clamping force to the upper insulating rod of the two adjacent insulating rod sections. When the eccentric handle 26 is in the high position, the part of the open clamp located above the transverse dividing seam 22 applies an inward clamping force to the upper insulating rod of the two adjacent insulating rod sections, thereby firmly locking and fixing the upper insulating rod of the two adjacent insulating rod sections. Here, it is defined that when the eccentric handle 26 is rotated from the low position to the high position, the eccentric handle 26 is in the locked state, that is, the locking component is in the locked state. When the eccentric handle 26 is rotated from the high position to the low position, the eccentric handle 26 is in the unlocked state, that is, the locking component is in the unlocked state.

[0025] like Figure 3 As shown, the adjustable connector includes a first connector 4 fixed to the top of the quick-release connector 3, a plurality of first protrusions 5 arranged in a circular array and fixed at intervals on one side of the first connector 4, a plurality of second protrusions 7 arranged in a circular array and inserted between the plurality of first protrusions 5, a second connector 6 fixed on the plurality of second protrusions 7, a fastening bolt 9 detachably connected to the first connector 4 and the second connector 6 and passing through the first connector 4 and the second connector 6, and a fastening washer 8 sleeved on the screw of the fastening bolt 9 near the end of the nut, wherein the end of the second connector 6 is detachably connected to the wire cutter mechanism 10. Specifically, in this embodiment, the fastening bolt 9 is a wing bolt. The first connecting member 4 includes a first connecting plate, a first circular plate fixed on the first connecting plate, and a threaded hole in the middle of the first circular plate. A plurality of first protrusions 5 are fixed at equal intervals on the periphery of one side of the first circular plate. The second connecting member 6 includes a connecting post with a threaded rod, a second connecting plate fixed on the connecting post, a second circular plate fixed on the second connecting plate, and a U-shaped hole on the second circular plate. A plurality of second protrusions 7 are fixed at equal intervals on the periphery of one side of the second circular plate. The plurality of second protrusions 7 can be inserted precisely between the plurality of first protrusions 5. The screw in the fastening bolt 9 passes through the fastening washer 8, the U-shaped hole on the second circular plate, and the threaded hole in the middle of the first circular plate in sequence, and fastens the first connecting member 4 and the second connecting member 6 together.

[0026] The wire cutter mechanism 10 adopts a wireless remote-controlled rechargeable wire cutter, which is an existing structure. This wireless remote-controlled rechargeable wire cutter has a rechargeable battery and can cut power cables via remote control. Furthermore, the wire cutter mechanism 10 is provided with a threaded connection hole that matches the threaded rod on the second connecting member 6, and the threaded rod on the second connecting member 6 is threaded into the threaded connection hole.
