Abstract
The utility model discloses a stainless grounding assembly specially used for distribution wires and ground wires on a railway passenger car, which comprises a grounding seat support, an aluminum alloy grounding seat and two rivets. The grounding seat support is made of Q235A and the overall surface is galvanized. The middle one section of the grounding seat support is sunken and two first rivet holes with counterbores are arranged along the length direction on the section. Two second rivet holes and two tapped bind holes are symmetrically arranged along the length direction on the aluminum alloy grounding seat. The two second rivet holes on the aluminum alloy grounding seat are arranged from the bottom top and are corresponding to the two first rivet holes on the grounding seat support. The two tapped bind holes on the aluminum alloy grounding seat are arranged from the bottom top. The two rivets pass through the second rivet holes on the aluminum alloy grounding seat and the first rivet holes on the grounding seat support respectively from the bottom up to enable the two to be fixedly connected. The stainless grounding assembly specially used for distribution wires and ground wires on a railway passenger car has the beneficial effects that antirust effects are good; and as the first rivet holes are provided with the counterbores, the bottom surface of the aluminum alloy grounding seat can be ensured to be flat, and the ground wires can be ensured to be reliably grounded.
Description
Technical field
The utility model relates to passenger train technical field, particularly a kind of stainless ground connection sub-assembly that is exclusively used in distribution and ground wire on passenger train.
Background technology
Along with the continuous upgrading of passenger train vehicle in recent years, each rolling stock section of Railway Bureau requires more and more higher to the security reliability of electric device operation on passenger train, and assurance electric device safety is distribution safety at all, except carrying out the basis protection such as wire casing, spool, junction box, distribution, earthing effect also can not be ignored.
In recent years, in long-time running, there is electric device on the unreliable car causing of ground connection and moved bad phenomenon in passenger train again and again, and to passenger train, potential safety hazard is buried in operation.Existing most of common railway passenger vehicle is by distribution and ground wire is directly riveted on car body steel skeleton and the vitals such as Wire casing boxes, junction box does not have ground connection.
Mainly there are following 3 deficiencies in the earthing mode therefore, having from the summary of experience of using:
1, because rivet is not all stainless material, grown easily service time and got rusty, thereby caused ground connection loosening, affected the normal use of power device in car;
2, the position of riveted joint ground wire is directly by manual grinding, smooth not, thereby fastening not while causing earth connection riveted joint, easily loose or dislocation;
3, in long-time running, earth connection and rivet all easily get rusty, become flexible, come off, and electric leakage accident very easily occurs.
Utility model content
Goal of the invention of the present utility model is: for the problem of above-mentioned existence, provide a kind of stainless ground connection sub-assembly that is exclusively used in distribution and ground wire on passenger train.
The technical solution adopted in the utility model is such:
A kind of stainless ground connection sub-assembly that is exclusively used in distribution and ground wire on passenger train, comprise grounding base support, aluminium alloy grounding base and two rivets, described grounding base support is that Q235A manufacture and integral surface are zinc-plated, in the middle of grounding base support, on one section of sinking and this section, be provided with along its length two rivet holes one of counterbore, described aluminium alloy grounding base is symmetrical arranged two rivet holes two and two tapped blind holes along its length, two rivet holes two on described aluminium alloy grounding base are offered from the bottom to top, and corresponding with two rivet hole one positions on grounding base support, two tapped blind holes on described aluminium alloy grounding base are offered from the bottom to top, described two rivets are fixedly connected with the two with the rivet hole one on grounding base support through the rivet hole two on aluminium alloy grounding base respectively from the bottom up.
Owing to having adopted technique scheme, the beneficial effects of the utility model are: grounding base support is cheap for manufacturing cost, favorable rust preventing effect; Rivet hole one, with counterbore, has guaranteed the planarization of aluminium alloy grounding base bottom surface, guarantees ground wire reliable ground, and safety assurance is provided; Aluminium alloy grounding base integral body is aluminium alloy manufacture, can not get rusty, and good antirust property.
As preferably, rivet hole two and tapped blind hole are distributed on the center line of aluminium alloy grounding base.Rivet hole two and tapped blind hole are distributed on a center line, are conducive to whole sub-assembly more stable.
As preferably, the thick 3mm of described grounding base support, long 100mm, wide 20mm, height overall 20mm, middle sinking segment length 60mm, rivet hole one aperture 4mm; The long 60mm of described aluminium alloy grounding base, wide 20mm, thick 15mm, rivet hole two aperture 4mm.These sizes of this sub-assembly, consider on passenger train that for special actual conditions comprehensively draw everywhere, and on passenger train, versatility is high.
