Description

Technical Field

[0001] The invention belongs to the technical field of electric power and building construction, and particularly relates to a method for tamping an electric grounding pole. Background Art

[0002] In the construction, reconstruction, maintenance and rectification of substations, power transmission and distribution lines, and lightning protection grounding electrode construction, the grounding electrode needs to be set in the foundation by tamping. At present, most of the power grounding electrode tamping methods use manual and mechanical tamping of the grounding electrode made of angle steel into the foundation. However, since most of the construction sites are in the field, they are greatly affected by weather, environment, and terrain, and large-scale machinery and equipment cannot reach the site. Therefore, the construction workers can only use the hammer method to hit the top of the grounding electrode to make it go underground. At present, most of the power workers are over 50 years old, and they are indeed a bit overwhelmed by the physical work of swinging a hammer, so they can only take turns to operate; in addition, the grounding electrode is usually 2.5 meters long, and it is not easy to install the grounding electrode by manual operation. It will take a lot of time, especially when the person swinging the hammer is tired. If the sledgehammer falls, it will hit himself or the handle of the sledgehammer will hit the top of the grounding electrode, causing the hammer head to fly out and hurt others; at the same time, the 2.5-meter-long grounding electrode needs to be tamped on a stepladder, which is easy to cause a high-altitude fall accident due to loss of balance, and it will also cause damage to the top of the grounding electrode such as curling and tearing. Summary of the invention

[0003] In order to solve the above problems, the object of the present invention is to provide a method for tamping an electric grounding electrode.

[0004] In order to achieve the above object, the electric grounding pole tamping method provided by the present invention comprises the following steps performed in sequence:

[0005] 1) Prefabricate a clamping block assembly; the clamping block assembly comprises a right clamping block, a left clamping block and a locking bolt; wherein a protrusion with a cross section of an isosceles triangle and a vertex angle of 90 degrees is protruded outwardly from the middle of one side of the right clamping block, and the plane where the triangle is located is a horizontal plane; a groove with the same size and shape as the above-mentioned protrusion is formed inwardly from the middle of one side of the left clamping block; the middle of the grounding electrode is located between the protrusion and the groove; the four corners of the side of the right clamping block and the left clamping block are connected together by locking bolts, thereby clamping the grounding electrode, and a hammering hole is formed in the middle of the right clamping block along the vertical direction;

[0006] 2) When it is necessary to set a grounding electrode in the foundation, the construction personnel shall place the protrusion on the right clamping block and the groove on the left clamping block in the clamping block assembly on the inner and outer sides of the grounding electrode 1 meter away from the lower end, and then connect the four corners of the side of the right clamping block and the left clamping block together with locking bolts until the grounding electrode is firmly clamped;

[0007] 3) One construction worker places the grounding electrode upright on the ground where the grounding electrode is set, and another construction worker inserts the hammer head of a heavy electric pick into the striking hole on the right clamping block from top to bottom;

[0008] 4) Start the heavy-duty electric pick, and use the weight of the right clamping block, the left clamping block and the heavy-duty electric pick as well as the rapid impact force of the heavy-duty electric pick to move the grounding electrode downward and insert the lower end vertically into the foundation;

[0009] 5) When the lower part of the grounding electrode is inserted into the foundation for a certain distance, loosen the locking bolt, then move the right clamping block and the left clamping block up along the grounding electrode, then re-tighten the locking bolt, and then repeat step 4) until the grounding electrode reaches the designed position, and finally remove the heavy electric pick and clamping block assembly.

[0020] The right clamping block 1 and the left clamping block 2 are made by separating a 200mm×200mm square iron block through wire cutting.

[0021] The surfaces of the protrusion 4 and the groove 5 are rough surfaces, which can prevent the right clamping block 1 and the left clamping block 2 from sliding downward.

[0022] The diameter of the striking hole 6 is 50 mm, which is slightly larger than the diameter of the hammer head on the heavy electric pick, so that the heavy electric pick can be quickly removed from the right clamping block 1 when an unexpected situation occurs.

[0023] 2) When it is necessary to set the grounding electrode 7 in the foundation, the construction personnel shall place the protrusion 4 on the right clamping block 1 and the groove 5 on the left clamping block 2 in the clamping block assembly on the inner and outer sides of the grounding electrode 7 at a distance of 1 meter from the lower end, and then connect the four corners of the side of the right clamping block 1 and the left clamping block 2 together with the locking bolts 3 until the grounding electrode 7 is firmly clamped;

[0024] 3) One construction worker places the grounding electrode 7 upright on the ground where the grounding electrode 7 is set, and another construction worker inserts the hammer head of a heavy electric pick into the striking hole 6 on the right clamping block 1 from top to bottom;

[0025] 4) Start the heavy-duty electric pick, and use the weight of the right clamping block 1, the left clamping block 2 and the heavy-duty electric pick as well as the rapid impact force of the heavy-duty electric pick to move the grounding electrode 7 downward and vertically insert the lower end into the foundation;

[0026] 5) When the lower part of the grounding electrode 7 is inserted into the foundation for a certain distance, loosen the locking bolt 3, then move the right clamping block 1 and the left clamping block 2 up along the grounding electrode 7, then re-tighten the locking bolt 3, and then repeat step 4) until the grounding electrode 7 reaches the designed position, and finally remove the heavy electric pick and clamping block assembly.
