Description

Technical Field

[0001] This utility model relates to the field of high-altitude cable hanging technology, specifically to a high-altitude cable threader. Background Technology

[0002] During power grid line maintenance and routine power line installation, it is often necessary to pass conductors or leads through specific locations at high altitudes. The work site environment is complex, and obstacles such as tree branches and beams are often present along the cable path. When encountering such obstacles, existing methods typically include: clearing or removing the obstacles first, attempting to have the operator carry the cable up to bypass the obstacles, or directly climbing onto the obstacles to carry out the operation.

[0003] However, clearing or removing obstacles may increase workload and have an environmental impact; climbing or ascending obstacles is not only inefficient, but also greatly increases the safety risks such as falls from heights, posing a threat to the personal safety of workers.

[0004] Therefore, there is an urgent need for a specialized tool that can help workers quickly and safely traverse such obstacles. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a high-altitude wire threading device to overcome the shortcomings of low efficiency and poor safety of existing operation methods, and to assist operators in quickly and safely completing high-altitude obstacle threading operations.

[0011] When the lever rotates around the hinge axis, the locking part can press against or disengage from the locking part, and cause the elastic reset member to produce corresponding elastic reset or compression deformation.

[0012] To better achieve the above technical solution, optionally, the lever is L-shaped, and its hinge is located in the turning area where the long side and the short side of the lever meet.

[0013] Optionally, the locking portion is a circumferentially arranged annular structure.

[0014] Optionally, the locking part has a hemispherical structure, and its contact surface for engaging with the locking part is a flat surface.

[0028] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. Identical components are indicated by the same reference numerals.

[0029] Please see Figures 1 to 5 This utility model discloses a high-altitude cable threader, including a long rod clamping rod 10, a plug rod 20, a displacement tube 30, and a lever locking mechanism 40.

[0030] like Figure 2 As shown, the front end of the long rod clamping rod 10 is provided with a pair of clamping arms 11 that can be opened and closed relative to each other. The clamping arms 11 are semi-circular or elliptical structures. In this embodiment, the clamping arms 11 are elliptical structures. This structure can better surround and adapt to obstacles 50 of various shapes and sizes, increase the effective operating space, reduce the alignment accuracy requirements, and improve the versatility and fault tolerance of the equipment.

[0031] It should be noted that the long clamping rod 10 is an existing mature product. Its handle is equipped with a button 12. Pressing the button 12 will unfold the two clamping arms 11. After releasing the button 12, the two clamping arms 11 will automatically close under the action of the internal mechanism (not shown in the figure). This is a technology well known to those skilled in the art, and the specific structure will not be described in detail.

[0032] There are two insertion rods 20, which are coaxially fixedly installed on the opposite inner sides of the front end of the two clamping arms 11. Specifically, the insertion rod 20 is a straight rod, and it and the corresponding clamping arm 11 are an integral structure. The integral structure can give the insertion rod 20 sufficient structural strength and stability.

[0033] The shift tube 30 has insertion holes at both ends, which are used to connect with the two insertion rods 20. The outer walls at both ends of the shift tube 30 are provided with locking parts 31. The middle part of the outer wall of the shift tube 30 is integrally provided with a terminal post 32 for connecting the wire 60. The insertion structure allows the shift tube 30 to move between the two insertion rods 20. In this embodiment, the inner wall of the insertion hole and the outer wall of the insertion rod 20 can be set as a rough structure, which can effectively enhance the friction after insertion and prevent the shift tube 30 from sliding relative to the insertion rod 20 under unexpected circumstances, thereby improving the stability of the working state.

[0034] The lever locking mechanism 40 includes a pair of levers 41 symmetrically arranged on both sides of the central axis of the clamping arm 11. The middle part of each lever 41 is hinged to the corresponding clamping arm 11 via a hinge shaft. The front end of the lever 41 is provided with a locking part 42 for pressing and engaging with the locking part 31. The rear end of the lever 41 is connected to an elastic reset member 43, which is preferably a coil spring. The other end of the elastic reset member 43 is connected to the clamping arm 11. When the lever 41 rotates around the hinge shaft, the locking part 42 can press or disengage from the locking part 31, and cause the elastic reset member 43 to undergo corresponding elastic reset or compression deformation. This lever locking mechanism 40 utilizes the lever principle to convert the contact force of the obstacle 50 into the release force of the lever locking mechanism 40, realizing the function of one-way automatic unlocking, and thus achieving non-reverse threading.

[0035] In a preferred embodiment, the lever 41 is L-shaped, with its hinge located at the junction of the long and short sides of the lever. This structure helps to reduce accidental contact with the lever 41 when moving the high-altitude cable threader.

[0036] In a preferred embodiment, the locking part 31 can be a circumferentially arranged annular structure, the locking part 42 is a hemispherical structure, and its contact surface for cooperating with the locking part 31 is a flat surface. The above structure can ensure smooth and stable cooperation.

[0037] In a preferred embodiment, the long rod clamping rod 10 is an insulated rod, which is crucial for high-risk environments such as power construction. It can effectively isolate high voltage, prevent electric shock accidents, and ensure the personal safety of operators.

[0038] The working principle of the high-altitude cable threader in this embodiment of the utility model is as follows:

[0039] like Figure 1 As shown, in its natural state, the two clamping arms 11 are in a closed state under the action of the internal mechanism (not shown in the figure).

[0040] like Figure 2 As shown, when it is necessary to pass the wire 60 through the obstacle 50, first fix one end of the wire 60 to the terminal 32 of the displacement tube 30. The operator presses the button 12 on the handle of the long rod clamping rod 10 to unfold the two clamping arms 11. At this time, one end of the displacement tube 30 is already fitted onto the right-side insertion rod 20.

[0041] like Figure 3As shown, move the entire high-altitude cable threader so that the obstacle 50 enters the space enclosed by the two clamping arms 11. Release the button 12, and the two clamping arms 11 will close together, so that the insertion hole at the other end of the shift tube 30 is fitted onto the insertion rod 20 on the left side. At the same time, under the action of the elastic reset member 43, the pair of locking parts 42 of the lever locking mechanism 40 are pressed against the locking parts 31 at both ends of the shift tube 30, thereby locking the shift tube 30 between the two clamping arms 11.

[0042] like Figure 4 As shown, by slightly moving the high-altitude cable threader, the obstacle 50 touches the rear end of one side lever 41, causing the lever 41 to rotate around its hinge point, resulting in the locking part 42 at its front end disengaging from the corresponding locking part 31, while the locking part 42 on the other side remains locked.

[0043] like Figure 5 As shown, the operator presses button 12 on the handle of the long rod clamping rod 10 to unfold the two clamping arms 11. At this time, the shifting tube 30 moves to the insertion rod 20 on the left side to complete the shift. Continuing to move the high-altitude cable threader will allow the wire 60 to smoothly bypass the obstacle 50 and complete the cable threading process.

[0044] This utility model discloses a high-altitude wire threading device that utilizes the insertion and connection of the insertion rod and the displacement tube, the automatic locking and one-way trigger unlocking mechanism of the lever locking mechanism, and the operation of the insulated long rod to achieve safe, efficient, and reliable wire threading across obstacles in high-altitude environments. It features simple structure, easy operation, high safety, and strong adaptability.

[0045] The technical solution of this utility model has been described in detail above with reference to specific embodiments. The specific embodiments described are used to help understand the concept of this utility model. Derivations and modifications made by those skilled in the art based on the specific embodiments of this utility model also fall within the protection scope of this utility model.
