Description

Technical Field

[0001] The utility model relates to the technical field of electric power construction equipment, in particular to a portable insulating clamp for live working. Background Art

[0002] In the power industry, live working is an important maintenance method to ensure the safety of power supply equipment and improve the quality of grid services. Live wire cutting is a common operation in distribution network operations. Currently, most wire cutting operations use insulating methods, that is, using wire cutters with insulating rods or using insulating gloves. The entire process requires the use of a variety of insulating protective equipment and insulating tools. The operators are under great psychological pressure, the work intensity is high, the work efficiency is low, and it is easy to cause safety accidents.

[0003] During live work, especially when replacing electrical components in a distribution box, there are many wires in the distribution box. When replacing or repairing electrical components, multiple live wires on the electrical components need to be cut and then processed live. During this process, since the cut ends of the wires are live, if they touch other wires or other electrical components, there will be a great safety hazard, and it may even cause the distribution box to burn and cause a fire. In addition, the personal safety of the workers is not guaranteed. The workers need to pay attention to the placement of each wire at all times and sometimes need to hold the wires. In the prior art, such as Chinese patent CN202220093392.0, a clamp device for disconnecting leads is disclosed. In this patent, a robot is used to complete live work to cut and clamp the wires. However, this device is mainly used for directly cutting cables and cannot accurately cut and clamp the multiple wires in the electrical components. In addition, after cutting the wires, wiring is still required. Such live work currently requires manual operation. Therefore, it is necessary to develop supporting construction equipment for the above-mentioned dangerous operations to reduce operational risks. Utility Model Content

[0005] The technical solution adopted by the present utility model is: a portable insulating clamp for live working, comprising an insulating clamp main body, the insulating clamp main body is made of insulating material, the insulating clamp main body comprises a first component and a second component hinged to each other by a pin shaft, wherein the first component comprises a first handle and a first clamping rod connected to each other, the second component comprises a second handle and a second clamping rod connected to each other, the first handle and the second handle are both arranged behind the pin shaft, the first clamping rod and the second clamping rod are both arranged in front of the pin shaft, the inner side of the first clamping rod is provided with a plurality of first slots spaced apart from each other along its own length, the inner side of the second clamping rod is provided with a plurality of second slots spaced apart from each other along its own length, the insulating clamp main body has a clamping state, in the clamping state, the first clamping rod and the second clamping rod are closed together, the first slot hole and the second slot hole cooperate to form a clamping hole for clamping the live broken wire, and at least one magnetic block is installed on the insulating clamp main body.

[0006] Several optional methods are also provided below, but they are not intended to be additional limitations on the above-mentioned overall solution. They are merely further supplements or optimizations. Under the premise that there are no technical or logical contradictions, each optional method can be combined separately for the above-mentioned overall solution, or multiple optional methods can be combined.

[0007] Preferably, the live wire disconnector has a wire break end, which extends to one side of the clamping hole. The insulating clamp also includes an insulating bag, which is made of a flexible insulating material. The insulating bag is detachably fixed between the first clamping rod and the second clamping rod, and covers the wire break end.

[0008] Preferably, two mounting edges are provided on one side of the insulation bag, and the two mounting edges are respectively fixed to the first clamping rod and the second clamping rod by a plurality of fixing screws, and wrinkles are respectively provided on the front and rear sides of the insulation bag.

[0009] Preferably, the magnetic block is fixed to the end of the first clamping rod.

[0010] Preferably, the length of the first handle is greater than the length of the second handle.

[0015] More preferably, the inner walls of the first slot and the second slot are both provided with anti-slip pads.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. Since the insulation clamp is made of insulating material, when the wire with the broken end is clamped in the clamping hole, the exposed live parts will not conduct electricity to the operator;

[0018] 2. Use an insulating bag to cover the broken end to provide further protection for the broken end and prevent operators from accidentally touching the broken end during operation.

[0019] 3. Since the insulation clamp is provided with multiple clamping holes, it can clamp multiple wires at the same time;

[0020] 4. By fixing the magnetic block at the end of the first handle, after all the broken wires are clamped on the clamping hole, the insulation clip can be adsorbed on the metal surface by magnetic attraction, which is convenient for operators to change wires. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Specific implementation plan: see Figure 1-Figure 3 The utility model is a portable insulating clamp for live working, comprising an insulating clamp body, the insulating clamp body being made of insulating material, the insulating clamp body comprising a first component and a second component hinged to each other by a pin, wherein the first component comprises a first handle 1 and a first clamping rod 3 connected to each other, the second component comprises a second handle 2 and a second clamping rod 4 connected to each other, the first handle 1 and the second handle 2 are both arranged behind the pin, the first clamping rod 3 and the second clamping rod 4 are both arranged in front of the pin, the inner side of the first clamping rod 3 is provided with a plurality of first slots 31 spaced apart from each other along its own length, the inner side of the second clamping rod 4 is provided with a plurality of second slots 41 spaced apart from each other along its own length, the insulating clamp body has a clamping state, in which the first clamping rod 3 and the second clamping rod 4 are closed together, the first slot 31 and the second slot 41 cooperate to form a clamping hole 5 for clamping the live broken wire, and at least one magnetic block 8 is installed on the insulating clamp body.

[0031] As a preferred implementation of this embodiment, the live wire disconnector has a wire break end, which extends to one side of the clamping hole 5. The insulating clamp also includes an insulating bag 9, which is made of a flexible insulating material. The insulating bag 9 is detachably fixed between the first clamping rod 3 and the second clamping rod 4, and covers the wire break end.

[0032] Then, see Figure 1 and Figure 3 It can be seen that in this embodiment, two mounting edges 10 are provided on one side of the insulation bag 9, and the two mounting edges 10 are respectively fixed to the first clamping rod 3 and the second clamping rod 4 by a plurality of fixing screws 11, and the front and rear sides of the insulation bag 9 are respectively provided with pleated portions 91.

[0033] In this embodiment, the first clamping rod 3 is provided with a plurality of first screw holes 32 spaced apart from each other, the second clamping rod 4 is provided with a plurality of second screw holes 42 spaced apart from each other, and the mounting edge 91 is provided with a plurality of through holes, the first screw holes 32 and the second screw holes 42 both correspond to the positions of the through holes, and after the fixing screws 11 pass through the through holes, they are screwed and fixed in the first screw holes 32 and the second screw holes 42, thereby achieving the two mounting edges 10 being fixed on the first clamping rod 3 and the second clamping rod 4 respectively.

[0034] To ensure safety, in this embodiment, the fixing screw 11 is an insulating screw.

[0035] In addition, in this embodiment, since the front and rear sides of the insulation bag 9 are respectively provided with pleated portions 91, and the insulation bag 9 is made of a flexible material, during the opening process of the insulation clamp, the pleated portions 91 will expand (the expansion amplitude of the pleated portions 91 at the front end is greater than the expansion amplitude of the pleated portions 91 at the rear end), and the inner cavity of the insulation bag 9 will increase. During the closing process of the insulation clamp, the pleated portions 91 will shrink, and the inner cavity of the insulation bag will decrease, thereby ensuring that the insulation bag is always fixed on one side of the first clamping rod 3 and the second clamping rod 4.

[0036] When the wire is cut, the inner core of the wire end is exposed. The operator must first open the insulation clamp. Figure 2 At this time, the insulation clamp is opened, and then the remaining wires after cutting are clamped into the first slot 31 from the side facing away from the insulation bag 9 (because the wires and the first slot 31 match and clamp, the wires can be preliminarily positioned), and the broken wire ends enter the insulation bag 9. Next, please refer to Figure 1 By holding the first handle 1 and the second handle 2 and pressing them inward, all the wires can be clamped in the clamping hole 5. At this time, the exposed broken ends of all the wires are located inside the insulating bag 9, and there is no risk of leakage or accidental touch.

[0037] Then, see Figure 1 It can be seen that in this embodiment, the magnetic block 8 is fixed to the end of the first clamping rod 3.

[0038] Note that the magnetic block 8 must be a strong magnetic block 8 and is set at the end of the first clamping rod 3. After the operator clamps all the wires that need to be connected in the clamping hole 5, the insulating clamp is placed close to the iron plate. Through the magnetic attraction of the magnetic block 8 and the iron plate, the insulating clamp can be adsorbed and fixed on the iron plate, which makes it convenient for the operator to operate.

[0039] Then, in this embodiment, the length of the first handle 1 is greater than the length of the second handle 2 .

[0040] Here, the length of the first handle 1 is increased to utilize the principle of leverage, reducing the required power by increasing the power arm, thereby making it easier to use the insulation clamp. This design makes the insulation clamp a force-saving lever, suitable for situations where greater force is required but hand strength is desired, thereby making it more convenient for operators to perform clamping operations.

[0041] Then, see Figure 1 It can be seen that in this embodiment, a logo sticker 6 is attached to the first handle 1 or the second handle 2 .

[0042] Here, when multiple line numbers and connections need to be replaced, the operator can write the line number and connection name on the identification sticker 6 and stick it on the first handle 1 or the second handle 2, so that the operator can check the corresponding wires clamped by the insulating clamp for subsequent line replacement.

[0043] In this embodiment, in the wire clamping state, the inner sides of the first clamping rod 3 and the second clamping rod 4 are in close contact with each other.

[0044] Next, in order to enhance the gripping feel, in this embodiment, gripping patterns are provided on the exterior of the first handle 1 and the second handle 2 .

[0045] In addition, in this embodiment, a handle cover 7 is provided on the outside of the first handle 1 .

[0046] Here, according to the corresponding clamped line phases as needed, and to distinguish different line phases, the colors of the handles on different insulation clamps (without the handle cover 7) or the colors of the handle cover 7 are different.

[0047] More specifically, the inner walls of the first slotted hole 31 and the second slotted hole 41 are both provided with anti-skid pads. Here, the design of the anti-skid pads can make the wires more stably clamped in the clamping hole 5.

[0048] The above description of the portable insulating clamp for live working of the present invention is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the description and drawings of the present invention under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
