Abstract

The utility model provides a shockproof lamp support for an electric locomotive, which relates to the lighting device of the electric locomotive and cooperates with an electric locomotive and a lamp, and consists essentially of a U-shaped framework, a sliding sleeve, a spring, a lamp cover, an end cover, a connection board and a fixing adjusting screw cap, etc. When the electric locomotive is in operation, the shake of the lamp gets buffer, reducing the damage to the lamp caused by shake. Moreover, the utility model not only protects the exposed lamp from breaking, avoids the accidents such as short circuit and wire breakage caused by exposed and irregular wire joints, and meets the provision of lighting at front and red lamp at back under Safety Regulations for Coal Mine, but also has advantages of simple structure and low coast as well as convenient manufacturing and installation and prolonging the service life of the bulb, thereby possessing perfect economic and social benefits.

Description

The shockproof lamp bracket of electric locomotive

The utility model relates to the bright device of transport plane licence, particularly mining electric haulage locomotive illumination equipment.

Mining electric locomotive illuminating lamp (hereinafter to be referred as lamp) all is to be fixed on the electric locomotive cover at present.One, because the bulb that vibrations cause in transportation damage phenomenon is very serious; Two, because lamp is exposed, the phenomenon that is smashed is also more serious; Three, the joint of lamp wiring is exposed, and lack of standardization, short circuit, broken string accident happen occasionally, cause burning the electric locomotive mains lighting supply, in producing at the scene, the circuit of lamp broken string sometimes, also not satisfying has the requirement that red light is arranged after the illumination before the electric locomotive that " safety regulations in coal mine " stipulate.Therefore, had a strong impact on safety in production and workman's life security.

The purpose of this utility model is to design a kind of electric locomotive lamp bracket that can reduce vibrations.

The purpose of this utility model also is to design and a kind ofly can reduces lamp vibrations and can prevent the electric locomotive lamp bracket that lamp is smashed again.

The purpose of this practical full mold also is to design a kind of lamp vibrations of can reducing, and prevents that lamp from being smashed, and the electric locomotive lamp bracket that is protected of lamp wiring joint.

The shockproof lamp bracket of the utility model electric locomotive is achieved in that

The utility model cooperates with electric locomotive and lamp, and its characteristics are mainly to comprise U type framework, spring, sliding sleeve, lampshade etc.; Described U type framework is to curve the approximate U-shaped body that two straight bar parts and sweep constitute by round bar; Described sliding sleeve is a cylindrical shape, two; Described lampshade is a cylindrical shape; Described spring is four; Divide on the cylinder of two groups of two straight bar parts that are enclosed within U type frame; Described two sliding sleeves lay respectively between two springs of every group of spring, the cylinder running-fit of its inner cylinder and U type framework straight bar part; The outer cylinder and the lampshade of two sliding sleeves are affixed; Described lampshade and lamp are affixed, and make lamp towards lampshade through hole direction; The upper end and the electric locomotive cover of two straight bar parts of described U type framework are affixed.

In the above-mentioned technical scheme, two straight bar part lower ends of described U type framework have a fixing spring packing ring affixed with it respectively near the position of sweep; Electric locomotive cover through hole is passed in two straight bar part upper ends of described U type framework, there is the screw thread of being longer than electric locomotive cover through hole length its upper end, there are four to adjust hold-doun nut, per two top and bottom that lay respectively at electric locomotive cover through hole, and with U type framework straight bar part upper end screw thread fit.

The utility model can also be realized like this:

On the basis of technique scheme, its characteristics also are an inclined-plane that end face is an approximate ellipsoidal of described cylindrical shape lampshade, and make the bus of top lampshade cylinder of lamp the longest, there are three circular holes that are mutually 120 degree lamp to be fixed in the lampshade that (lamp is existing approved product by three bolts in the lampshade, there are three screws in the outer garden of lamp, connects by three screws and lampshade).

The utility model can also be realized like this:

On the basis of technique scheme, its characteristics are that also the end cap of a planar shaped is connected by the end cap bolt of rear end plate with the other end of lampshade, and make this end sealing; Also has a through hole on the described end cap; There is the outer cylinder of a columnar cable sheath to cooperate, and stretches in the lampshade with the inner cylinder of end cap through hole; Two bolts are arranged on end cap, link to each other with the cable tension disc of a lampshade planar shaped outward; Have in the described lampshade one flat and the touch block of shape is affixed with it, and it is not collided with end cap; Five binding posts are arranged on the described touch block; Cable (drawing voltage 12-36V from the electric locomotive mains lighting supply) passes exterior cable tension disc of end cap and cable sheath and enters in the lampshade, joins by five binding posts and lamp wiring.

The utility model has such characteristics:

1, because the utility model has designed the lamp bracket structure with spring and sliding sleeve, make the vibrations of lamp in the electric locomotive operational process obtain buffering, therefore, reduced the corrupted that causes lamp because of vibrations effectively.

2, because the utility model is sent out the lampshade of having counted special construction, lamp is fixed in the lampshade, therefore, has prevented the phenomenon that lamp is smashed effectively.

3, because the utility model design-calculated lampshade has structures such as end cap, tension disc, touch block; the joint of lamp wiring is protected; therefore avoided short circuit, broken, burnt the generation of accidents such as electric locomotive mains lighting supply, also realized " safety regulations in coal mine " regulation before the requirement that red light is arranged after the illumination is arranged.

4, the utility model is skillfully constructed, and is simple in structure, manufacturing, easy for installation, so cost is lower, has prolonged the service life of bulb effectively, has guaranteed workman's life security, has good economic benefits and social benefit.
