Description

Technical Field

[0001] This utility model belongs to the field of power tool technology, and in particular relates to a multi-axis damping adjustment device for working with insulating rods. Background Technology

[0002] In the power industry, to reduce power outage time and ensure continuous power supply, it is often necessary to perform operations while the conductors are energized. Live-line work can prevent power interruptions caused by maintenance and repairs, which is especially important for locations requiring continuous power supply. For example, by using specially designed safety tools such as wire strippers, the wire stripper is lifted by a long insulating rod to strip the wires. The operator can perform the operation while standing on the ground, away from the energized conductor, which is not only simple to operate but also greatly improves safety. In practical applications, conductors often exhibit a drooping arc structure due to their own weight. In specific working conditions, the operator is often not directly below the operating position. Therefore, there needs to be a margin of movement between the stripper and the insulating rod, allowing the insulating rod to freely tilt and lift the stripper.

[0003] Chinese patent document CN109873372B discloses a ground potential preheating live-line stripping device, comprising a main frame. A guide block is fixedly installed on the inner wall of the main frame using countersunk screws. A heating plug is mounted on the main frame. A T-shaped threaded sleeve is fixedly connected to the bottom of the main frame via a first thrust ball bearing. A universal insulating rod is fitted onto the surface of the T-shaped threaded sleeve. This device allows for safe and convenient live-line stripping without power interruption. Furthermore, it enables live-line ground potential connection of insulated overhead lines in power distribution networks, expanding the applicability of live-line ground potential connection and maintenance connections. It solves the problem that due to increasing power grid technical requirements, more and more distribution lines are insulated, and live-line connection cannot be achieved without energizing the insulation layer of the insulated wire.

[0004] In the aforementioned patented solution, the ball head on the peeler is rolled onto the insulating rod, providing the peeler with a margin of movement, and a universal locking plate locks the ball head for positioning. However, due to the peeler's considerable weight and the relatively small contact area between the ball head and the universal locking plate, the universal locking plate needs to provide sufficient friction to the ball head to stabilize the peeler's posture. This requires tightening the locking screw with considerable force to ensure the universal locking plate provides sufficient contact strength to the ball head. On one hand, the tightening force required for the locking screw is high, and loosening or tightening requires tools, making manual operation inconvenient. On the other hand, due to the small contact area of ​​the ball head, over time, scratches and pits will appear on the surface of the ball head, reducing its lifespan and deteriorating its locking effect in the later stages. Utility Model Content

[0005] To overcome the technical problems in existing technologies where the contact area between the ball head and the universal locking plate between the insulating rod and the stripper is small, requiring a large frictional force on the ball head to stabilize the stripper's posture, resulting in a large tightening force on the locking screw, which is inconvenient for manual operation and long-term use, this utility model aims to provide a multi-axis damping adjustment device for insulating rod operation. This device provides a margin of movement by setting two damping sections with perpendicular rotation directions between the insulating rod and the operating device. The damping sections are locked by the frictional force between the outer wall of the frustum column and the inner wall of the concave frustum tube. This results in a larger contact area, requiring only a smaller locking force to provide greater friction. Furthermore, the larger contact area prevents scratches and pits, extends service life, improves locking durability, and facilitates manual operation and long-term use.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a multi-axis damping adjustment device for operating insulating rods, comprising an insulating rod, an operating device, and two damping parts respectively disposed on the insulating rod and the operating device; each damping part includes a concave frustum tube, a frustum column coaxially rotatably connected within the concave frustum tube, and an adjusting screw threaded onto the frustum column for pressing the concave frustum tube; the outer wall of the frustum column abuts against the inner wall of the concave frustum tube; wherein, the frustum column in one damping part is disposed on the concave frustum tube in the other damping part; the rotation axes of the frustum columns in the two damping parts are perpendicular to each other.

[0007] Furthermore, the adjusting screw passes through both the corresponding concave frustum tube and the frustum column; the frustum column is provided with an embedded nut that is threadedly connected to one end of the corresponding adjusting screw; and an anti-loosening washer is provided between the other end of the adjusting screw and the corresponding concave frustum tube.

[0008] Specifically, the end of the frustum column away from the adjacent concave frustum tube is coaxially provided with a concave cavity; the bottom of the concave cavity is provided with a non-circular hole; the embedded nut is located in the non-circular hole; the outer contour of the embedded nut and the inner contour of the non-circular hole are both non-circular in shape.

[0009] Furthermore, at least one elastic gasket is provided between the anti-loosening gasket and the concave frustum tube; the elasticity of the elastic gasket is used to press the outer wall of the frustum column against the inner wall of the concave frustum tube.

[0010] Specifically, the elastic gasket is a corrugated gasket.

[0011] Furthermore, a plum blossom pressure plate is provided on the frustum column of the damping part located on the insulating rod; a plum blossom joint is provided at the end of the insulating rod and is rotatably connected to the plum blossom pressure plate; the rotation axis of the plum blossom joint is perpendicular to the rotation axis of the frustum column of the two damping parts respectively; a fastening screw for locking the two together is provided between the plum blossom joint and the plum blossom pressure plate.

[0012] Furthermore, an equipment mounting plate is provided on the concave frustum tube in the damping section of the working device; the working device is mounted on the equipment mounting plate.

[0013] Preferably, the end of the adjusting screw away from the adjacent frustum column is provided with a butterfly head.

[0014] Optionally, in the frustum column and the concave frustum tube arranged together, the axis of the frustum column and the axis of the concave frustum tube are located on the same plane.

[0015] Optionally, in the frustum column and the concave frustum tube arranged together, the axis of the frustum column and the axis of the concave frustum tube are respectively located on two mutually perpendicular planes.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model uses an insulating rod lifting device for operation. The two damping parts provide multiple degrees of freedom for the position adjustment of the device, making the operator's work position and the posture of the device more flexible. The damping parts can be fully locked to lock the posture of the device, or partially locked, allowing the posture of the device to be adjusted under damping conditions, making the use of the device more flexible.

[0018] 2. This utility model uses the elastic force of the elastic gasket to press the outer wall of the frustum column and the inner wall of the concave frustum tube together, and the damping force of the two can be adjusted by rotating the adjusting screw; at the same time, the corrugated gasket also reduces the contact area with the concave frustum tube, that is, reduces the rotation resistance of the adjusting screw, making it easier for personnel to operate.

[0019] 3. This utility model uses a concave frustum tube and a frustum column as damping parts, which result in a larger friction contact surface. Only a small locking force is needed to provide a large friction force, and no tools are required for locking, making it easy to operate manually. At the same time, due to the larger friction contact surface, stress concentration will not occur on the contact surface, that is, no scratches or pits will be generated on the friction surface, resulting in a longer service life and a more durable and stable locking effect.

[0020] 4. This utility model has a simple structure, small size, compact and concentrated design, which facilitates production and assembly. At the same time, there are no fine or micro-structures in the whole structure, and the overall structural strength is also higher, which can provide a more stable and higher holding torque for the working device, making it particularly suitable for working devices with large gravity.
