Embodiment Construction
[0029] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0030] like figure 1 and figure 2 The shown telescopic hoisting beam for a coal mine monorail crane includes a load-bearing beam 3, a load-bearing trolley 2 and a telescopic arm 5. The load-bearing trolleys 2 are respectively provided above the ends of the load-bearing beam 3, and the load-bearing trolleys 2 and The monorail 1 is matched, and the load-bearing beam 3 is hoisted on the monorail 1 by the carrying trolley 2 and reciprocates along the monorail 1, and is characterized in that:
[0031] like image 3 As shown, upper chute 11 and lower chute 12 are respectively set in the middle of the load-bearing beam 3 along the height direction. The upper chute 11 and the lower chute 12 are both set to open on one side, the opening ends of the upper chute 11 and the lower chute 12 are in opposite directions, and the telescopic arms 5 are respect...
