Abstract
Description
Technical Field
[0001] The utility model belongs to the field of static electricity elimination tools, in particular to a magnetic static electricity grounding clamp. Background Art
[0002] During the loading process of railway tank cars for railway transportation of hazardous chemicals, it is necessary to connect the railway tank cars with electrostatic grounding devices to conduct static electricity generated during the loading process. At present, the storage and transportation workshop uses electrostatic grounding clamps to connect with railway tank cars, and uses electrostatic grounding clamps to pierce the paint, stains and other insulating layers on the surface of the clamping parts of the railway tank cars through paint-breaking needles to conduct static electricity to eliminate the static electricity hazards generated by tank car filling. However, during the loading process, railway tank cars are often accompanied by high-frequency vibrations, and the electrostatic grounding clamps are displaced under the vibration of the tank cars. The paint-breaking needles contact the paint layer, resulting in poor connection of the electrostatic grounding clamps, and even disconnection of the electrostatic grounding clamps from the clamping parts, making it impossible to conduct static electricity, posing a major safety hazard. Utility Model Content
[0003] The technical problem to be solved by the utility model is that the electrostatic grounding clamp is displaced under the vibration of the tank truck, and the paint-breaking needle contacts the paint layer, resulting in poor connection of the electrostatic grounding clamp and failure to conduct static electricity.
[0004] In order to solve the above technical problems, the specific technical solutions of the utility model are as follows:
[0005] A magnetic electrostatic grounding clamp comprises an electrostatic grounding clamp and a magnetic device; the magnetic device is fixedly connected to the electrostatic grounding clamp; the magnetic device comprises an insulating plate 8 and a magnetic base 10, the insulating plate 8 is in the shape of a long strip, the top ends of the two magnetic bases 10 are respectively fixed at the two ends of the insulating plate 8, and the bottoms of the two magnetic bases 10 are both provided with magnets 11; the middle opening of the insulating plate 8 cooperates with the paint-breaking needle on the electrostatic grounding clamp.
[0006] Among them, the electrostatic grounding clamp includes an upper clamp body 1 and a lower clamp body 2, the upper and lower clamp bodies are hinged by a pin shaft 3, and the two are rotated to form a clamp body. A torsion spring is provided at the rotational cooperation position of the upper and lower clamp bodies. An upper paint-breaking needle 4 is provided on the inner side of the front end of the upper clamp body, and two lower paint-breaking needles 5 are provided on the inner side of the front end of the lower clamp body. The length of the upper paint-breaking needle is greater than that of the lower paint-breaking needle. The upper and lower paint-breaking needles are arranged in a serrated shape at the front end of the electrostatic clamp. The rear end of the upper clamp body is bent outward to form an upper clamp body pressing part, and the rear end of the lower clamp body is bent outward to form a lower clamp body pressing part. The rear end of the upper clamp body is connected to a grounding cable 6, and the rear end of the lower clamp body is connected to a grounding anti-pull steel cable 7. The rear ends of the upper and lower clamp bodies are provided with anti-slip protrusions.
[0007] The utility model has the following advantages: the magnetic suction device can make the electrostatic grounding clamp tightly adsorbed on the clamping part of the tank car, and in the vibration environment of loading, the paint-breaking needle of the electrostatic grounding clamp cannot move, so the static electricity can be effectively discharged; it effectively solves the problem that in the high-frequency vibration environment of the railway tank car during loading, the electrostatic grounding clamp moves, causing poor contact and triggering the alarm of the electrostatic grounding system, thereby eliminating the safety hazard of static electricity accumulation.
