Description

High-altitude wiring clamp

Technical Field

The utility model relates to an electric power wiring detects technical field, in particular to high altitude wiring pincers.

Background

According to the maintenance test regulations of the power company, when a high-voltage circuit breaker carries out preventive tests such as loop resistance, PT/CT dielectric loss and capacitance test, on-site maintenance test personnel often use high-altitude wiring clamps to hang test wires for the tests. The height of the existing 500kV high-voltage circuit breaker is generally about 10 meters, the length of a used high-altitude wiring clamp device is also about 10 meters, and the weight of an operating rod of the high-altitude wiring clamp and a test wire reaches 15 kilograms. Although the weight of a single rod is not heavy, the gravity center of the operating rod of the overhead wire connecting clamp is far away from the operating part of a human hand, the generated force arm is large, and then the operating rod can be lifted by an abnormally large operating force. And because lack guider and strutting arrangement, on-spot peg often can not accurate control action bars's direction, leads to pole falling and disconnected pole risk easily. In addition, when field test, especially when the synchronous test is needed, the test method requires three-phase synchronous test, so 3 high-voltage wires and 6 low-voltage wires need to be hung at the corresponding positions of three phases respectively, 9 test wires are needed in total, 9 high-altitude wiring clamp operating rods need to be used, and the total weight exceeds 135 kilograms. The traditional hanging rod and hanging method have great potential safety hazards: firstly, the direction of an operating rod cannot be accurately controlled, and the risks of damaging power equipment and personal injury caused by rod reversing exist; secondly, the operating rod of the high-altitude wiring clamp device is too long and heavy, and a gravity supporting device is not arranged at the middle upper part of the operating rod, so that the shearing force at the lower part of the operating rod is too large, and the risk of rod breaking exists; thirdly, the number of the required high-altitude wiring clamp operating rods is large, 9 operating rods and test wires of 15 kilograms are required for simultaneous three-phase measurement according to the number of the three operating rods which are hung on one phase, and the labor intensity of field personnel is increased, and especially when the high-altitude wiring clamp works in extreme weather, the safety risk of personnel and equipment can be brought.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described clearly and completely with reference to fig. 1 to 4 of the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art without any inventive work based on the embodiments in the present application are within the scope of protection of the present application. Thus, the following detailed description of the embodiments of the present application, as presented in the figures, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments obtained by a person of ordinary skill in the art without any inventive work based on the embodiments in the present application are within the scope of protection of the present application.

As shown in FIGS. 1 to 4, a high altitude jointing clamp comprises a jointing clamp 1. The jointing clamp 1 refers to a common double-spring hook design, and can also be directly transformed by adopting the double-spring hook.

The fixed release rope fixed part 2 that is provided with in one side of the U-shaped clamp body open end of binding clip 1, release rope fixed part 2 can be trompil on the fastener or weld on the fastener, threaded connection wiring end, and this embodiment adopts and welds a ring in the binding clip side and realizes.

The other side traditional double-spring ground rod of U-shaped clamp body open end is used for the fixed release rope guide ring 3 that is provided with in one side of fixed action bars, and release rope guide ring 3 is the ring structure, preferably adopts the copper ring to make, welds the opposite side at U-shaped clamp body open end.

As shown in fig. 1 and 2, the release cord guide ring 3 and the release cord fixing portion 2 correspond to each other: the release rope guide ring 3 and the release rope fixing part 2 are arranged at a horizontal height and are positioned at the U-shaped opening, and the hole axis direction of the release rope guide ring 3 corresponds to the release rope fixing part 2.

One end of the release rope 4 is fixed on the release rope fixing part 2, the fixing mode can be a binding mode, a buckling mode, a pressure riveting mode and the like, and the other end of the release rope 4 penetrates through a ring hole of the release rope guide ring 3. The diameter of the annular ring of the release cord guide ring 3 should be greater than the diameter of the release cord 4 so that the release cord 4 is free to slide within the release cord guide ring 3.

The fixed taut rope fixed part 5 that is provided with below the binding clip 1, taut rope fixed part 5 can be bolt, hole or other structures that can fix the rope, and the preferred ring structure that adopts of this embodiment is about to one ring welding in the bottom of fastener one end of installation action bars at ordinary times. One end of the tension rope 6 is tied and fixed on the tension rope fixing part 5.

The upper surface of the jointing clamp 1 is fixedly provided with a hanging ring 8. The suspension ring 8 is of a circular ring structure and should be made as large as possible.

The release rope 4 and the tensioning rope 6 are soft ropes made of insulating materials.

During the use, get in touch in four shaft unmanned aerial vehicle bottom installations, for example four anchor couple, tie up on the unmanned aerial vehicle support with rope one end, the department in the middle of four anchor couples is tied up to the rope other end. Hook four anchor couple to rings 8 to start unmanned aerial vehicle and fly, thereby drive this wiring pincers and rise. Utilize remote controller remote control unmanned aerial vehicle to fly to the wire top that needs the test to aim at this wire and descend unmanned aerial vehicle with the U-shaped jaw of wiring pincers, U-shaped jaw articulates on the wire this moment, and the couple breaks away from rings 8 automatically, has just can retrieve unmanned aerial vehicle. Meanwhile, the tensioning rope 6 is pulled on the ground by hand, so that the wiring clamp 1 moves downwards, the tested lead is clamped in the U-shaped jaw, and meanwhile, as a part of the releasing rope 4 traverses the U-shaped jaw, the releasing rope 4 positioned on the U-shaped jaw is pushed upwards by the lead to form a U-shaped structure under the action of the tension of the tensioning rope 6. The wire can be connected and tested after being clamped into the double-spring tongue piece.

When the wiring clamp is lifted off to needs, remote control unmanned aerial vehicle rises to the air and aims at rings 8 with the couple, contacts the back when couple and rings 8, in ground pulling release rope 4, because the pulling force effect, is located release rope 4 on the U-shaped jaw and is stretched straightly, and simultaneously with 1 upwards ejecting of binding clip, just can separate it and wire smoothly, rethread unmanned aerial vehicle slowly transfers it and can realize dismantling work.

Through carrying out the improved design on the basis at original two spring couple, utilize unmanned aerial vehicle to promote and articulate, can reduce operating personnel and carry hundreds of kilograms's equipment, also do not have the danger of backlashes moreover, improved work efficiency greatly.

Considering that the opening of the wire clamp is small and the wire is not easy to align, in one embodiment, in order to increase the contact surface of the jaw, a guide strip 7 is fixedly arranged below one side of the opening end of the U-shaped clamp body of the jointing clamp 1, and the guide strip 7 is made of a rigid material into a cylindrical rod-shaped structure.

In view of the fact that the drone cannot be too heavy, in one embodiment, the suspension ring 8 is a circular ring structure made of light plastic or foam.
