[0018] As shown in the figure, the base 1 is a horizontally placed rectangular steel plate, and the base 1 is welded and fixed to the running mechanism of the large loading equipment. The conductive wire 2 is a copper wire, and the upper and lower ends of the conductive wire 2 are respectively fixedly connected to the base 1 and the carbon roller 8 by bolts 3 to ensure the grounding conductivity of the lightning protection grounding device.

[0019] As shown in the figure, a spring bracket 4 is welded on the bottom surface of the base 1. The spring bracket 4 is two parallel steel pipes. The upper ends of the two steel pipes are vertically welded to the bottom surface of the base 1. There are multiple beams 5 welded in parallel between the two steel pipes to ensure the firmness of the spring bracket 4.

[0020] As shown in the figure, there are adjustment screw holes on the lower tube walls of the two steel tubes of the spring bracket 4, and the front ends of the two adjustment bolts 7 are respectively connected to the compression springs 6 in the two steel tubes through the adjustment screw holes, and the rear ends of the two adjustment bolts 7 are tightened by a wrench. The length of the compression spring 6 can be adjusted by adjusting the bolt 7, so that its spring force acts on the carbon roller fixing bolt 9, thereby adjusting the compression elastic force of the carbon roller 8 of the compression spring 6. The compression spring 6 and the fixing bolt 8 are rolling friction, which does not affect the rotation of the carbon roller 8, ensuring the conductivity of the grounding device.

[0021] The figure shows that the carbon roller 8 is located below the spring bracket 4. The carbon roller 8 is a horizontal cylinder. The cylinder of the carbon roller 8 is placed on the upper surface of the track 15, and the carbon roller 8 and the track 15 are in rolling cooperation. There are screw holes in the center of the two end faces of the carbon roller 8, and the fixing bolts 9 are fastened to the screw holes in the center of the end faces of the carbon roller 8. The carbon roller 8 of an embodiment of the utility model is made of metal graphite carbon roller J202. While ensuring the hardness of the carbon roller 8, the material can ensure the grounding conductivity of the grounding device. The carbon roller 8 contacts the track 15 in real time to reduce the current surge impact and protect the electrical equipment.

[0022] As shown in the figure, the sweeper 10 is installed in front of the carbon roller 8, and the front end of the sweeper 10 is in sliding contact with the surface of the running track 15. The sweeper 10 is used to remove debris accumulated on the track 15 and clean the track 15 to ensure good electrical contact between the carbon roller 8 and the track 15.

[0023] The figure shows that the sweeper 10 is an N-shaped steel frame, and the three plates of the N-shaped frame are respectively vertical. The two side plates 11 of the N-shaped frame of the sweeper 10 are parallel to the track 15. The rear ends of the two side plates 11 have connection holes. The connection holes at the rear ends of the two side plates 11 are respectively sleeved on the rod bodies of the fixing bolts 9 at both ends of the carbon roller 8. The connection holes and the rod bodies of the fixing bolts 9 are rotatably connected. When the fixing bolts 9 rotate with the carbon roller 8, the two side plates 11 of the sweeper 10 can be kept in a horizontal position. Ensure that the polyurethane block 14 fits tightly with the track 15, but does not hinder the movement of the large machine.

[0024] As shown in the figure, the middle of the two side plates 11 of the N-shaped frame of the sweeper 10 are connected by a crossbar 13, and a polyurethane block 14 is fixed on the crossbar 13. The lower end of the polyurethane block 14 is in sliding fit with the upper surface of the track 15. The polyurethane block 14 can effectively remove dust particles on the track 15, reduce the friction coefficient between the carbon roller 8 and the track 15, and ensure good electrical contact between the carbon roller 8 and the track 15. At the same time, the crossbar 13 can also be quickly removed, which is convenient for the later maintenance and care of the polyurethane block 14.

[0025] The figure shows that the front ends of the two side plates 11 of the N-shaped frame of the sweeper 10 are equipped with a transverse plate 12, and the front ends of the two side plates of the N-shaped frame of the sweeper 10 are respectively provided with sockets, and the two ends of the front end transverse plate 12 of the N-shaped frame of the sweeper 10 are respectively bent at 90 degrees, and the bends at both ends of the transverse plate 12 are tightly plugged with the sockets of the front ends of the two side plates 11. It can also have a good cleaning effect on some larger foreign objects, and at the same time, it stabilizes the structure of the polyurethane block 14, slows down the wear of the polyurethane block, and greatly increases the service life of the carbon roller 8.
