Abstract
The invention provides a self-descaling ground clamp which comprises a main shaft and a transmission shaft. The main shaft is connected with the transmission shaft through a gear set I, the transmission shaft is connected with a lower contact through a gear set II, the main shaft penetrates through the upper end face of a body and is connected with an upper pressing contact, and the upper pressing contact and the lower contact are provided with a sharp body and a scraper respectively. The main shaft drives the lower contact to rotate through the gear sets and the transmission shaft, and the rotation direction of the lower contact is opposite to that of the upper pressing contact, so that the scraping effect is better, positioning of a ground line is stable, the ground line is not prone to sliding, and the self-descaling function can be achieved. The body is connected with an auxiliary wire clamp and a ground line connection screw hole, and the auxiliary wire clamp and the ground line connection screw hole are suitable for grounding lines with zinc coatings as grounding electrodes. During operation, the auxiliary wire clamp is directly connected with the ground and can rotate by certain angles to be applied to different work spaces.
Description
Technical field
The present invention relates to a kind of earthing clamp, relate in particular to a kind of from scale removal earthing clamp.
Background technology
Electrical equipment grounding, is a very important technical safety measures in electrical construction operation, and it concerns construction operation personnel's personal safety and the safe operation of electric equipment.Therefore, need the ground connection effect must be good, if ground connection resistance is excessive, life security and device security that the electric current producing suddenly will serious threat workmen, and whether ground connection is good, the effect that contacts of the earthing clamp depending primarily on and earth electrode.When carrying out this work, operating personnel need to clear up impurity such as iron rust, paint and dirts in the ground connection position on earth electrode with file, wire brush, to guarantee that earthing effect is good at present.But at some special location and special space, cannot use the instruments that take out stains such as file, wire brush, in order to overcome above deficiency, the invention provides a kind of from scale removal earthing clamp, can fundamentally solve this difficult problem, the specific function of its use device self, efficient and convenient, high-quality and high-efficiency that electrical equipment grounding work is become.
Summary of the invention
The technical problem to be solved in the present invention is that ground connection position exists the foreign material such as iron rust, paint and dirt, affects earthing effect.For addressing the above problem, provide a kind of from scale removal earthing clamp, this earthing clamp can rotate by the upper and lower contact of gear driven, on upper and lower contact, sharp-pointed body and type scraping knife is installed, the descaling function on the ground wire surface that can achieve a butt joint.
The object of the invention is to realize by following manner: should comprise main shaft and power transmission shaft from scale removal earthing clamp, main shaft is connected with power transmission shaft by a gear train, power transmission shaft is connected with lower contact by a gear train, and described main shaft is connected with upper compression contact through the upper surface of main body; On described upper compression contact and lower contact, sharp-pointed body and type scraping knife are housed.Described upper compression contact is connected with main body by compression spring.Between described main body and upper compression contact, be provided with external spring.In described main body, be provided with ground wire and connect the auxiliary wire clamp of screw.Described power transmission shaft, through upper surface and the lower surface of main body, is placed in the inner side of main body.
Beneficial effect of the present invention: 1, turning handle, under the effect of main shaft, upper compression contact moves down and rotates, and under the effect of revolving force and sharp-pointed body and type scraping knife, makes shaving effect more obvious.2, between main shaft and upper compression contact, be connected with compression spring, between main body and upper compression contact, be connected with external spring, the pressure size by two adjustable upper compression contacts of spring to earth electrode.3, main shaft drives lower contact to rotate by gear train, power transmission shaft, and lower contact rotation direction and upper compression contact direction of rotation, make the better while of shaving effect, and earth wire location is more steady, is difficult for sliding.4, in main body, be connected with auxiliary wire clamp and ground wire and connect screw, can be for the ground connection earth connection of zinc coat very.During operation, auxiliary wire clamp is directly connected over the ground, the auxiliary rotatable certain angle of wire clamp adapts to different working spaces.
