Summary of the invention
The object of the invention is to the deficiency overcoming prior art, provide a kind of diesel locomotive that can solve can ensure locomotive equipment and safe in operation problem, effective diesel locomotive lightning protection device saving traffic cost when highlands thunder and lightning is frequent.
The object of the invention is to be achieved through the following technical solutions, a kind of diesel locomotive lightning protection device, comprise the electric installation be fixed on combustion engine steering frame journal box body, first cable, second cable, first cable and second cable series connection, its node is fixed on truck frame, the lower end of first cable is fixed on mount pad, and the upper end of second cable is fixed on locomotive car body; Mount pad is fixed on journal box body by insulcrete, evenly on mount pad be laid with spring fixing groove, spring fixing groove is provided with U-shaped spring bracket, and Compress Spring is fixed on U-shaped spring bracket, Compress Spring compresses carbon brush, and the end of carbon brush is fixed on mount pad by soft line; The end of diesel locomotive axletree is provided with friction disc, and carbon brush makes brush and the friction disc close contact of carbon brush by Compress Spring.
In order to realize object of the present invention better, described friction disc is circular copper-tin alloy friction disc.
In order to realize object of the present invention better, two described cables are cross-sectional area is 300mm
2tin copper product cable and outer be surrounded by insulation, wear-resisting mesh grid.
In order to realize object of the present invention better, described mount pad is provided with corrosion-resistant steel end cap.
In order to realize object of the present invention better, described mount pad is uniformly distributed three carbon brush.
In order to realize object of the present invention better, described mount pad adopts brass material.
The invention has the beneficial effects as follows, by structural development and the cross-sectional area strengthening carbon brush and cable, conductive capability is stronger, thunder and lightning transient high-current is avoided bearing directly flow into the wheel shaft of rotation by car body and pass on rail, avoid bearing galvanic corrosion, cause bearing damage, avoid thunder and lightning hit car body and affect traffic safety, ensure that diesel locomotive thunder and lightning take place frequently area safe in operation, reduce and send accessory to highlands, reduce traffic cost, solve the problem of diesel locomotive without lightning protection device.

Detailed description of the invention
For making goal of the invention of the present invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, carry out clear intactly describing to technical scheme of the present invention, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
See accompanying drawing, diesel locomotive lightning protection device of the present invention is by the electric installation be fixed on combustion engine steering frame journal box body 1 and first cable 14, second cable 17 is formed, first cable 14 is connected with second cable 17, its node is fixed on truck frame 15, the lower end of first cable 14 is fixed on mount pad 9, and the upper end of second cable 17 is fixed on locomotive car body 16; Electric current is made to form loop like this, thunder and lightning hits locomotive car body 16, electric current is by car body 16 steering bogie framework 15, electric installation is flowed to by cable 14 again from truck frame 15, electric installation is by conduct current bearing outer end cap 11, electric current is avoided bearing roller by bearing outer end cap 11 and directly to be led axletree 13, then flows to rail by wheel.The mount pad 9 of brass material is fixed on journal box body 1 by insulcrete 2, evenly on mount pad 9 be laid with three spring fixing groove 5, spring fixing groove 5 is provided with U-shaped spring bracket 6, Compress Spring 4 is arranged on U-shaped spring bracket 6 by rivet, Compress Spring 4 compresses carbon brush 3, and the end of carbon brush 3 is fixed on mount pad 9 by soft line 8; The end of diesel locomotive axletree 13 is provided with friction disc 10, and carbon brush 3 makes brush and friction disc 10 close contact of carbon brush 3 by Compress Spring 4, and friction disc 10 roughness of surface is better, can extend the carbon brush life-span largely, resistance to abrasion and conducting electricity very well.
First cable 14 and second cable 17 all adopt cross-sectional area to be 300mm
2tin copper product and outer be surrounded by tough and tensile PET monofilament braiding webmaster, there is insulation, wear-resisting and flame resistance, cable 14 can be prevented when locomotive operation and journal box body 1 connects mill, preventing the electric current of conduction when connecing mill by journal box body 1 center bearing pilot bearing 12 simultaneously.Because cable is that gun-metal is made, cross-sectional area is comparatively large, can conduct larger instantaneous current, and conductive capability is stronger, which solves current diesel locomotive and there is the problem of traffic safety hidden danger without lightning protection device in the thunder and lightning area that takes place frequently.
For preventing dust from falling into, mount pad 9 is bolted corrosion-resistant steel end cap 7.
During concrete enforcement, Compress Spring hold down groove 5 is fixed on mount pad 9 inner ring position, during use, clutch U-shaped spring bracket 6, U-shaped spring bracket 6 is inserted Compress Spring hold down groove 5, Compress Spring 4 rivet is fixed on U-shaped spring bracket 6, then makes Compress Spring 4 be positioned at the end of carbon brush 3, and letting go, it is fixing to realize.
