Abstract

Provided is a locomotive head lamp detecting screen, comprising a screen, a height adjusting rod, a support, and a universal wheel. The locomotive head lamp detecting screen is characterized in that: the screen 1 and the support 3 are connected via a bolt; the adjusting rod 2 and the support 3 are in threaded connection and can adjust the screen height according to the requirement; and the universal wheel 4 and the support 3 are also in threaded connection, with the support being a weld structure. The locomotive head lamp detecting screen is used for adjusting the head lamps of 350 attached locomotives. After the adjustment, the locomotive drivers reflect that the head lamps work well and the secure operation of the locomotives is ensured.

Description

Engine hatch lamp detects screen

Technical field

The utility model relates to a kind of light and detects screen, relates in particular to the head lamp detection screen of a kind of railway with locomotive.

Background technology

The quality of engine hatch lamp range adjustment is related to the train application safety, but receives effects limit such as on-the-spot place, light in the locomotive operation process, in system-wide the adjustment of locomotive range is not had comparatively complete method of adjustment and the device of a cover at present.

Summary of the invention

The goal of the invention of the utility model is technical requirement and the on-site actual situations according to " People's Republic of China's railway systems standard " defined; A kind of engine hatch lamp detection screen that existing locomotive uses that is suitable for is provided, and adjustment head lamp range satisfies the locomotive operation requirement.

A kind of engine hatch lamp detects screen, comprises screen, height adjusting link, support and universal wheel, and it is characterized in that: screen is connected with bolt with support; Adjusting lever and support are for being threaded; Can adjust the screen desired height, universal wheel is all with support and is threaded, and support is a welded structure.

The utility model relates to railway locomotive maintenance company, is the specific purpose tool of engine hatch lamp range adjustment.After detecting screen 350 engine hatch lamps of attaching troops to a unit are adjusted through the engine hatch lamp that utilizes the utility model, the locomotive steward reflects that generally headlight irradiation is all right, has guaranteed locomotive operation safety.

Embodiment

" People's Republic of China's railway systems standard " requires like following table range and light intensity:

Figure DEST_PATH_660916DEST_PATH_IMAGE001

Range, focal length adjustment principle is as shown in Figure 1, and AO is the headlamp height among the figure, and AG is the outgoing beam center line, and angle XAG is the headlamp level inclination, and OG is range.Main line SS3 type electric locomotive to use halogen tungsten lamp is example, and range OG must reach 510m, and locomotive headlamp height A O calculates with 4m.

Divide two kinds of situation discussion below: (1) supposition is after the abrasion of wheel footpath reach capacity 100mm (be AB 2 times); Headlamp height B O is 3.95m; If headlamp angle of inclination B FO remains unchanged; Be 504m through using ratio to calculate range OF, can not consider if find out the influence to range in the normal variation scope of headlamp height thus; (2) if we have confirmed the check point height, and fixing inconvenience, when detecting another locomotive,, become OH if this locomotive headlamp height increases or reduces, suppose AH=50mm=0.05m, through calculating the range OI=315m of this moment.The factor of being found out decision headlamp range by above two kinds of situations is the level inclination of headlamp, so check point height CE should change with locomotive headlamp height change.

By above analysis, according to " iron mark " and on-site actual situations, we can be whether inspection C place, 10m place produces the center speck at OE, and CE highly is 500 * AO ÷ 510, so we only need actual measurement locomotive headlamp setting height(from bottom) AO just can confirm the check point height.Make a central point then and be that CE, central point are positioned on the center line of rail, the length of side is 1m, observe the screen of center speck easily apart from the rail level height, the same big circle with the reflective mirror diameter of diameter is drawn by screen center.During detection this screen is positioned over the position of (because reflective mirror and cloche distance are about 0.5m) apart from locomotive headlamp vertical projection point 9.5m; Open headlamp; Inspection: whether the irradiation of (1) headlamp forms the center speck on screen, does not form the elevation angle or the focal length (OS in the headlamp irradiation principle schematic) of then adjusting headlamp; (2) whether the center speck overlaps with screen center circle zone basically, and speck shows then that greater than the center circle zone focal length is too small; Speck shows then that less than the center circle zone focal length is excessive; Speck left and right deviation central point shows BEAM SQUINT, must adjust the installation site of headlamp.

Check point definite as shown in Figure 2, (1) central point O: i.e. the central point of screen, S is the AC in the irradiation adjustment schematic diagram, because the actual headlamp elevation angle is less, far firing range is much larger than 10m, so AC ≈ OE is the desirable 10m of S.

(2) two level point A, B point: desirable ± 1.5 degree according to " iron mark ", AO=BO=S * tan1.5 ⁰=10m * 0.02618592=262mm.

(3) two vertical point C, D point: desirable ± 1.5 degree according to " iron mark ", CO=DO=S * tan1.5 ⁰=10m * 0.02618592=262mm.

It is as shown in Figure 3 that engine hatch lamp detects screen; Comprise screen, height adjusting link, support and universal wheel; It is characterized in that: screen 1 is connected with support 3 usefulness bolts, and adjusting lever 2 and support 3 can be adjusted and detect the screen desired height for being threaded; Universal wheel 4 is all with support 3 and is threaded, and support is a welded structure.

Claims

1. an engine hatch lamp detects screen; Comprise screen (1), height adjusting link (2), support (3) and universal wheel (4); It is characterized in that: screen (1) is connected with bolt with support (3); Adjusting lever (2) and support (3) are for being threaded, and universal wheel (4) is all with support (3) and is threaded, and support is a welded structure.
