Problems solved by technology

[0003] 1. High labor intensity, low efficiency and low level of automation;
[0004] 2. Operators directly contact high-voltage wires, which poses a great potential safety hazard;
[0005] 3. The safety protection and shielding requirements of manual live work are very strict. If you don’t pay attention, short-circuit current will occur, causing major safety accidents and personal casualties.

[0033] This embodiment provides a general-purpose live working tool with multiple clamps, such as figure 1 As shown, the installation side plate 1 is included, and the upper hook arm 201 and the lower hook arm 202 are provided on the installation side plate 1, which are opposite up and down and can be stretched. A rod 5 , the wire hook rod 5 is located between the upper hook arm 201 and the lower hook arm 202 .

[0034] The working process or working principle of the common live working tool with multi-clamp is as follows:

[0035] In the power industry, there are many kinds of wire clips. In order to conveniently illustrate the structure and working principle of the live working tool protected by the present invention, this embodiment takes the puncture wire clip 4 as an example. The structure of the puncture wire clip 4 is as follows: Figure 5 As shown, specifically, the staff turns the puncture wire clip 4 upside down (the nut is downward, such as image 3 shown) into th...

[0038] This embodiment provides a general-purpose live working tool with multiple clamps, such as figure 1 As shown, the installation side plate 1 is included, and the upper hook arm 201 and the lower hook arm 202 are provided on the installation side plate 1, which are opposite up and down and can be stretched. Rod 5 , the wire hook rod 5 is located between the upper hook arm 201 and the lower hook arm 202 .

[0039] Such as figure 1 and Figure 4 As shown, the upper hook arm 201 and the lower hook arm 202 have the same structure, and are composed of a first rod 6, a first spring 7, and a second rod 8 connected in sequence, and the first rod 6 is far away from One end of the first spring 7 is fixed to the installation side plate 1 and forms an included angle with the surface of the installation side plate 1, and the second rod 8 is provided with at least one bending portion 801 in the middle of the rod 1. A flat hook 802 is provided at the end, and the flat hook 802 of the...

[0043] On the basis of the first embodiment or the second embodiment, as a preference, such as figure 2 As shown, there are two lead wire hook bars 5, which are composed of a second spring 9 and a C-shaped hook 10. One end of the second spring 9 is fixed on the surface of the installation side plate 1, and the other end is connected to C-shaped curved hook 10.

[0044] Because the lead wire 15 in the lead wire port 16 of the puncture wire clamp 4 has a certain length, in order to maintain balance and ensure the stability of the lead wire 15, the C-shaped hook 10 is pulled, and under the elastic force of the second spring 9, the two C-shaped hooks 10 stretches out and catches the lead wire 15 simultaneously, and after the lead wire 15 is fixed, the upper hook arm 201 and the lower hook arm 202 can be pulled to carry out the next operation.

Abstract

The invention provides a multi-wire clamp universal live working tool and a using method thereof. The multi-wire clamp universal live working tool comprises an installation side plate, the installation side plate is provided with an upper hook arm and a lower hook arm which face to each other vertically and are stretchable and further provided with lead wire hook rods which are elastically stretchable, and the lead wire hook rod are located between the upper hook arm and the lower hook arm. A lead wire is fixed by the two lead wire hook rods with springs, then a wire clamp is opened by the upper and lower stretchable hook arms with springs to enable an opening of the wire clamp to be maximum, the error rate and deviation rate of wire clamp installation are significantly decreased, and convenience is brought to operation in actual work. In addition, the live working tool is encapsulated by adopting an insulating material and externally connected with a protection shell, the protection shell protects hooks and internal devices from being destroyed by collision, therefore, the safety coefficient can be better improved, and the safety of a worker is guaranteed.

Description

technical field [0001] The invention belongs to the field of electric tools, and in particular relates to a common live working tool with multiple clamps and a use method thereof. Background technique [0002] With the continuous development of power technology and the continuous improvement of social demand for power supply safety and stability, safe operation is becoming more and more important in various power technology industries. Among them, the safe installation of wire clips is a very important part of the work. At present, 10kV The mid-potential working method of the insulated arm truck is widely used in the distribution line work site, and the operator uses the original tools to manually complete the live work task. It has the following defects: [0003] 1. High labor intensity, low efficiency and low level of automation; [0004] 2. Operators directly contact high-voltage wires, which poses a great potential safety hazard; [0005] 3. The safety protection and ...
