Description

Technical Field

[0001] The invention relates to the field of electrical equipment testing, and in particular to a novel high-altitude wiring clamp. Background Art

[0002] After the power equipment is put into operation, it is necessary to carry out comprehensive testing and inspection at regular intervals to prevent the equipment from running with defects and endangering the safety of the power grid. During the test, it was found that the test terminal boards of some high-voltage equipment were very high, and the intervals were relatively narrow, so aerial work vehicles could not be used. It was easy for people to fall from heights and damage equipment when climbing ladders to connect wires, which was very dangerous.

[0003] For wiring of higher equipment, high-altitude clamps are used. The high-altitude clamps currently used are mainly of the pull-down type. The upper clamp hooks the equipment terminal board, and the insulating rod is pulled down by manpower to clamp the clamp. This results in insufficient clamping force, poor contact between the test line and the equipment terminal board, and large errors in test data. At the same time, the equipment is operated outdoors and the terminal board is severely oxidized. This wiring method cannot make the clamp teeth break the oxide layer, and there is also poor contact between the test line and the equipment terminal board, and large errors in test data, resulting in misjudgment of the equipment status during the test, which has a great impact on the guidance of maintenance work and equipment operation, and even poses a major safety hazard, endangering the safety of the power grid. Summary of the invention

[0023] like Figure 1 As shown, a novel high-altitude wiring clamp comprises an upper clamp 1 and a lower clamp 2; the upper clamp 1 comprises an upper clamp seat 11, an upper meshing tooth 12, a slide bar 13, a spring 14, and a positioning block 15; the lower clamp 2 comprises a lower clamp seat 21, a lower meshing tooth 22, and a sleeve rod 23;

[0024] The lower meshing teeth 22 are fixed to the top of the lower clamping seat 21; the upper meshing teeth 12 are fixed to the bottom of the upper clamping seat 11, and the upper clamping seat 11 is arranged opposite to the lower clamping seat 21, and the lower meshing teeth 22 mesh with the upper meshing teeth 12; the sleeve rod 23 is fixed to the end of the bottom of the lower clamping seat 21 away from the lower meshing teeth 22 and passes through the lower clamping seat 21; the sleeve rod 23 is a hollow rod, and a reverse "7"-shaped limiting groove 24 is provided on the sleeve rod 23;

[0025] The top of the slide bar 13 is fixed to the bottom of the upper clamping seat 11 and one end away from the upper meshing teeth 12. A positioning block 15 is fixed to the bottom of the slide bar 13. The spring 14 is sleeved outside the slide bar 13 and arranged on the positioning block 15. The slide bar 13 and the spring 14 are sleeved inside the sleeve rod 23, and the positioning block 15 moves along the limiting groove 24. The spring 14 is a compression spring.

[0026] The upper clamping seat 11 and the lower clamping seat 21 are both trapezoidal bodies, and a mounting groove is provided in the middle of the front half; the mounting groove of the upper clamping seat 11 faces downward, and is used to install the upper meshing tooth 12, and the rear end portion of the upper clamping seat 11 is processed with a screw hole adapted to the sliding rod 13, and the top of the sliding rod 13 is provided with an external thread, and the sliding rod 13 is fixedly connected to the screw hole at the rear end portion of the upper clamping seat 11 through the external thread; the mounting groove of the lower clamping seat 21 faces upward, and is used to install the lower meshing tooth 22, and the rear end portion of the lower clamping seat 21 is processed with a screw hole adapted to the sleeve rod 23, and the top of the sleeve rod 23 is provided with an external thread, and the sleeve rod 23 is fixedly connected to the screw hole at the rear end portion of the lower clamping seat 21 through the external thread.

[0027] The upper meshing teeth 12 are installed in the installation groove of the front half of the upper clamping seat 11 through an axle pin; the lower meshing teeth 22 are installed in the installation groove of the front half of the lower clamping seat 21 through an axle pin.

[0028] The upper meshing teeth 12 and the lower meshing teeth 22 respectively include a plurality of copper sheets with teeth, and a hole 4 is provided at the tail of the copper sheet for connecting the test line, so as to avoid a situation where a section of the copper sheet breaks through the film but is not a terminal, thereby affecting the conductive performance; the hole 4 on the copper sheet of the upper meshing teeth 12 is arranged at the top of the upper clamping seat 11, and the hole 4 on the copper sheet of the lower meshing teeth 22 is arranged at the bottom of the lower clamping seat 21. Copper sheet is an excellent conductive material compared to other common metals, and has excellent properties such as corrosion resistance, oxidation resistance, fatigue resistance and non-magneticity, so the upper meshing teeth 12 and the lower meshing teeth 22 are made of copper sheets.

[0029] The bottom of the slide bar 13 is provided with an external thread, and the slide bar 13 is connected to the positioning block 15 through the external thread at the bottom. A through hole matching the size of the outer diameter of the slide bar 13 is provided in the middle of the positioning block 15, and an internal thread is provided in the through hole; the positioning block 15 is fixedly connected to the slide bar 13 by matching the internal thread of the through hole with the external thread at the bottom of the slide bar 13; the positioning block 15 is provided with a protrusion, which protrudes from the outer wall of the sleeve rod 23 when the slide bar 13 is sleeved inside the sleeve rod 23, and moves in the limit groove 24.

[0030] The working principle of the present invention is: when in use

[0031] In the case of no external force, due to the elastic force of the spring 14 itself, the positioning block 15 will be at the bottom of the vertical part of the "7"-shaped limiting groove 24. When in use, the upper clamp 1 can be manually adjusted, that is, the positioning block 15 is moved to the horizontal part of the "7"-shaped limiting groove 24 in the opposite direction for limiting, so that the positioning block 15 is locked at the horizontal part of the limiting groove 24. In this process, the spring 14 is compressed, and the upper clamp seat 11 has a certain vertical distance from the lower clamp seat 21, and then the film can be manually broken. After the film breaking work is completed, the upper clamp 1 bites the clamping plate, and the positioning block 15 is unlocked from the horizontal part of the limiting groove 24. The elastic potential energy of the spring 14 is released, and the positioning block 15 is reset to the bottom of the vertical part of the limiting groove 24. In this way, the upper meshing teeth 12 of the upper clamp seat 11 and the lower meshing teeth 22 of the lower clamp seat 21 instantly bite the clamping plate, and the operator can perform the corresponding detection work.

[0032] Embodiment 2:

[0033] The present invention also includes an insulating rod joint 3, which is fixedly connected to the bottom of the sleeve rod 23 and is used to connect the insulating rod. The top of the insulating rod is provided with a thread, such as Figure 4As shown, the positioning block 15 is arranged above the bottom of the slide rod 13, at a certain distance from the bottom of the slide rod 13, and the portion of the slide rod 13 below the positioning block 15 is provided with threads, and the slide rod 13 is fixedly connected to the insulating rod by matching the threads provided at the portion below the positioning block 15 with the threads provided at the top of the insulating rod. When it is necessary to reset the positioning block 15 to the lowest end of the vertical portion of the limiting groove 24, the operator rotates the insulating rod to allow the positioning block 15 to slide out of the horizontal portion of the limiting groove 24, and the rest is the same as in Example 1.

[0034] The present invention is not limited to the specific implementation methods described above. The above is only a preferred implementation case of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
