Furthermore, the inner diameter of the lamp ring is 5-30 mm larger than the outer diameter of the coal shed stand column.

The utility model has the advantages that: the utility model discloses simple structure designs lift wire rope, loose pulley assembly and hoist engine, the lift of realization lamps and lanterns that can relax, makes illumination lamps and lanterns the unnecessary high altitude construction of staff when maintaining, maintaining and cleaning, not only can effectually improve work heroic efficiency and accord with operating mass with, moreover the effectual potential safety hazard of having eliminated is worth using widely on a large scale.

Description of the drawings:

FIG. 1 is a perspective view of the overall structure of the present invention;

FIG. 2 is an enlarged view of part A of FIG. 1;

in the figure, a coal shed upright post 1, a first guide pulley 2, a second guide pulley 3, a third guide pulley 4, a rotating shaft 5, a bearing seat 6, a second bend pulley 7, a third bend pulley 8, a lifting steel wire rope 9, a guide pulley 10, a winch 11, a first steel wire rope 12, a second steel wire rope 13, a third steel wire rope 14, a lamp ring 15 and an explosion-proof lamp 16.

The specific implementation mode is as follows:

as shown in fig. 1 and 2, a lifting lamp for a clean coal storage shed comprises a coal shed upright post 1, a first guide pulley 2, a second guide pulley 3 and a third guide pulley 4 are fixedly connected to the outer circumferential surface of the top end of the coal shed upright post 1 along the circumferential direction, a rotating shaft 5 is horizontally arranged at the top end of the coal shed upright post 1 close to the first guide pulley 2, two ends of the rotating shaft 5 are rotatably connected with bearing seats 6 through bearings, the bearing seats 6 are fixedly arranged at the top end of the coal shed upright post 1, a second direction-changing pulley 7 and a third direction-changing pulley 8 are fixedly connected to the top end of the coal shed upright post 1, a lifting steel wire rope 9 is further included, one end of the lifting steel wire rope 9 is vertically and downwards connected with a winch 11 after passing through the guide pulley 10, the guide pulley 10 and the winch 11 are fixedly arranged on the inner wall of the coal shed, the other end of the lifting steel wire rope 9 consists of a first steel wire rope 12, a second steel wire rope 13 and a third steel wire rope 14, the first steel wire rope 12 downwards rounds the rotating shaft 5 and the first guide pulley 2 and then is fixedly connected with a lamp ring 15, the second steel wire rope 13 rounds the second direction-changing pulley 7 and the second guide pulley 3 and then is fixedly connected with the lamp ring 15, the third steel wire rope 14 rounds the third direction-changing pulley 8 and the third guide pulley 4 and then is fixedly connected with the lamp ring 15, the lamp ring 15 is concentrically sleeved on the coal shed upright post 1 in a sliding manner, and a plurality of explosion-proof lamps 16 are uniformly and fixedly arranged on the lamp ring 15 along the circumferential direction; the inner diameter ratio of the lamp ring 15 is 5 mm-30 mm larger than the outer diameter of the coal shed upright post 1.
