The invention provides an angle adjustable lamp bracket and a test lamp. The angle adjustable lamp bracket comprises a mounting frame, lamp body supports and an angle adjusting assembly. The lamp bodysupports are pivoted to the mounting frame. The angle adjusting assembly comprises a motor, a speed reducer, winding reels, a steel wire, a fixed pulley, a movable pulley and a mounting plate. The motor, the speed reducer, the winding reels and the fixed pulley are all arranged on the mounting frame. The other end of the steel wire is connected with the fixed pulley, the movable pulley and the mounting plate in sequence. The steel wire is used for driving the lamp body supports to rotate through rotating of the winding reels with the pivot joints of the lamp body supports and the mounting frame as the centers, so that the ends, far away from the mounting frame, of the lamp body supports move close to or far away from the mounting frame. According to the angle adjustable lamp bracket, thelamp body supports are used for mounting illuminating lamps; the irradiation angle of the illuminating lamps on the lamp body supports is adjusted by adjusting the relative angle between the lamp bodysupports and the mounting frame. Accordingly, the irradiation angle can be adjusted according to the practical requirements.
Description
technical field [0001] The invention relates to the technical field of lamp holders, in particular to an angle-adjustable lamp holder and a test lamp. Background technique [0002] Rail cars (including trailers) are the main means of transportation for construction departments such as railway equipment maintenance, overhaul, and infrastructure construction to perform tasks. There are two types of railcars: heavy and light. Those that can be withdrawn from the line by passengers at any time are called light railcars; those that cannot be withdrawn from the line by passengers at any time are called heavy railcars. [0003] In the prior art, when performing a rail train collision test, it is necessary to illuminate the train in the track. Present illuminating lamp generally adopts lamp holder to fix, and makes the illuminating direction of illuminating lamp illuminate towards train during installation. [0004] However, the irradiation angle of the lighting lamp on the existi...
