The specific embodiment

The utility model relates to a kind of Material feeding trolley of industrial furnace, comprise chassis 1, feeding finger 2, be equipped with drive part on the chassis 1, comprise the motor 9 that is installed in above the chassis 1, reduction box 10, synchronously with 11 be installed in driving shaft 12 and driving wheel 13 below the chassis 1.A side is installed two parallel riser guides 3 on the chassis 1, mounting plate 5 between two riser guides 3, lifter plate 4 is installed above the fixed head between two riser guides 35, and feeding finger 2 is fixed on the lifter plate 4, and feeding finger 2 adopts the form of two parallel forks.Install on the fixed head 5 handle 7 and draining knob 8 are installed on oil pump 6, the oil pump 6, be connected with lifting drive between fixed head 5 and the lifter plate 4, promptly oil cylinder 16 is installed on the top of fixed head 5, an and fixing end of chain 7, fixed chain wheels 15 on the piston rod of oil cylinder 16, chain 7 strides across sprocket wheel 15, and its other end is fixed on the lifter plate 4, connects an oil pipe 17 between oil cylinder 16 and the oil pump 6.The upper design of riser guide 3 has wall scroll hoistway 19, and respectively there are up and down two directive wheels 18 both sides of lifter plate 4, and directive wheel 18 can free scroll-up/down fluctuating orbit 19 in, thus the elevating movement of realization lifter plate 4.

Material installs on the pallet, pallet is contained on the feeding finger 2, put neat, it is heavier that chassis 1 designs, by comprising motor 9, reduction box 10, be with 11 synchronously, the drive part of driving shaft 12 and driving wheel 13, dolly advances automatically, slides to the industrial furnace charging aperture, feeding finger 2 is sent into material in the industrial furnace, by regulating draining knob 8, the hydraulic oil in the oil cylinder 16 returns oil pump 6, and the piston rod of oil cylinder 16 shrinks, effect by sprocket wheel 15 and chain 14, lifter plate 4 reduces, thereby feeding finger 2 reduces, and can extract out below pallet, drive dolly and withdraw from industrial furnace, thereby material adds in the industrial furnace.

In fill process, feeding finger 2 may be more on the low side than the material carrier platform in the industrial furnace, then pulls handle 7, starts oil pump 6, hydraulic oil enters into oil cylinder 16 by oil pipe 17, the piston rod elongation of oil cylinder 16 by the effect of sprocket wheel 15 and chain 14, drives lifter plate 4 and raises, thereby raise feeding finger 2 and reach corresponding height, stop to pull handle 7, because the support of oil cylinder 16 inner high voltage oil makes feeding finger 2 keep this height.

Equally, in fill process, the height of feeding finger 2 may exceed the upper limb of industrial furnace material carrier platform, then regulates draining knob 8, and the hydraulic oil in the oil cylinder 16 returns oil pump 6, the piston rod of oil cylinder 16 shrinks, by the effect of sprocket wheel 15 and chain 14, lifter plate 4 reduces, thereby feeding finger 2 is reduced to corresponding height, stop to regulate draining knob 8, make feeding finger 2 keep this height.
