Description

TECHNICAL FIELD

[0001] The utility model relates to a belt self -moving tailstock technology field, specifically a kind of pressboard liftable belt self -moving tailstock trolley. BACKGROUND

[0002] Self -moving tailstock trolley arranges the groove of conveying belt by trolley pressboard, to ensure that the coal unloaded from transfer machine does not spill out of conveying belt. The working condition of fully mechanized coal face in coal mine is complex, the height of belt conveyor and the height of trolley conveying belt do not match, and uneven ground in mine will lead to inappropriate distance between conveying belt and trolley pressboard. If the distance is too small, it will cause serious wear of pressboard and conveying belt, and even cutting of conveying belt. If the distance is too large, it will cause pressboard to lose the effect of arranging the groove of conveying belt, and the unloaded section of transfer machine will be "coal spilled". Too small or too large distance between conveying belt and trolley pressboard is not conducive to safe, high-yield and efficient mining in coal mine. SUMMARY

[0003] The utility model aims at providing a kind of pressboard liftable belt self -moving tailstock trolley, which can solve the problem of serious wear of conveying belt and pressboard and coal spilled in the unloaded section of transfer machine caused by uneven ground and the height of belt conveyor and the height of trolley conveying belt do not match.

[0004] The utility model aims at providing a kind of pressboard liftable belt self -moving tailstock trolley, which can solve the problem of serious wear of conveying belt and pressboard and coal spilled in the unloaded section of transfer machine caused by uneven ground and the height of belt conveyor and the height of trolley conveying belt do not match.

[0005] A kind of pressboard liftable belt self -moving tailstock trolley, comprising trolley and pressboard lifting device, trolley comprises trolley body, T-shaped guide slot, pressboard lifting device comprises pressboard assembly, lead screw, nut, fixed plate;Trolley and pressboard lifting device are connected by lead screw and nut, pressboard lifting device is placed in the position of both sides of trolley, and pressboard lifting device can be lifted. Pressboard assembly is welded by pressboard and T-shaped guide strip, T-shaped guide strip is pressed into T-shaped guide slot from top to bottom, and pressboard is connected with lead screw by screw. Nut is loaded into the round hole of the joint plate of trolley body from bottom to top, fixed plate 24 is clamped into the annular groove of nut, and fixed plate and the joint plate of trolley body are connected together by bolt. Lead screw and nut are matched with each other, and both are trapezoidal thread.

[0006] The utility model has the advantages that by lifting the pressboard of belt self -moving tailstock trolley, the problem of serious wear of conveying belt and pressboard and coal spilled in the unloaded section of transfer machine caused by uneven ground and the height of belt conveyor and the height of trolley conveying belt do not match can be solved, the adaptability of underground equipment is improved, and production efficiency is improved.
