For of the present utility model a kind of preferred, top, drive sprocket both sides is respectively equipped with intermediate chain wheel, and chain is walked around drive sprocket left side intermediate chain wheel, drive sprocket and drive sprocket right side intermediate chain wheel successively.
For of the present utility model a kind of preferred, last forward beam lower end is provided with and advances slide rail I, following forward beam upper end is provided with and advances slide rail II, last forward beam left end below is connected with fixed glides I, and fixed glides I cooperates with advancing slide rail II, following forward beam right-hand member top is connected with fixed glides II, and fixed glides II cooperates with advancing slide rail I.
For of the present utility model a kind of preferred, following forward beam left end top is connected with normal valve.
For of the present utility model a kind of preferred, the drive sprocket central shaft hole is connected with the hydraulic motor clutch end, and normal valve is communicated with the hydraulic motor oil circuit.
The utility model is compared with background technology, and having one is that forward beam advances adjustable in length, has increased the compliance that drill carriage is adopted in the hole; The 2nd, stable drive, transmission efficiency height; The 3rd, cost is low, and is easy for installation.
The utility model is elaborated with reference to accompanying drawing below in conjunction with embodiment.
Description of drawings
Fig. 1 is the structural representation of the flexible forward beam of sprocket-type.
The specific embodiment
Embodiment 1: with reference to Fig. 1.The sprocket-type forward beam that stretches, comprise forward beam, forward beam comprises forward beam 10 and following forward beam 9, last forward beam 10 is positioned at forward beam 9 tops down, last forward beam 10 tops are provided with slide rail 14, and drill bar 8 cooperates with slide rail 14, and last forward beam 10 is provided with four groups of sprocket wheels 6 and middle two groups of sprocket wheel 6 centre-heights are lower than two ends sprocket wheel 6 centre-heights slightly, following forward beam 9 both sides are respectively equipped with sprocket wheel 6, and following forward beam 9 left ends below is provided with drive sprocket 5.Chain 7 one ends are connected with drill bar 8 right-hand members, its other end successively with forward beam 10 right side sprocket wheels 6, go up in the middle of the forward beam 10 near right side sprocket wheels 6, down forward beam 9 right side sprocket wheels 6, drive sprocket 5, down forward beam 9 left side sprocket wheels 6, be connected with drill bar 8 left ends with last forward beam 10 left side sprocket wheels 6 near left side sprocket wheels 6 in the middle of going up forward beam 10.Top, drive sprocket 5 both sides is respectively equipped with intermediate chain wheel 4, and chain 7 is walked around drive sprocket 5 left side intermediate chain wheels 4, drive sprocket 5 and drive sprocket 5 right side intermediate chain wheels 4 successively.Last forward beam 10 lower ends are provided with and advance slide rail I 12, following forward beam 9 upper ends are provided with and advance slide rail II 2, last forward beam 10 left ends below is connected with fixed glides I 13, and fixed glides I 13 cooperates with advancing slide rail II 2, following forward beam 9 right-hand members top is connected with fixed glides II 11, and fixed glides II 11 cooperates with advancing slide rail I 12.Following forward beam 9 left ends top is connected with normal valve 1.Drive sprocket 5 central shaft holes are connected with the hydraulic motor clutch end, and normal valve 1 is communicated with the hydraulic motor oil circuit.
Embodiment 2: with reference to Fig. 1.The sprocket-type forward beam operating principle of stretching: hydraulic motor drives drive sprocket 5 rotations, thereby drives the work of whole chain transmission system.Because forward beam 10 is light much on the weight ratio of drill bar 8, so the frictional force that drill bar 8 is subjected to is littler than last forward beam 10.Therefore, when chain drive was started working, chain drive made drill bar 8 advance on last forward beam 10 earlier or retreats.When drill bar 8 slides into the two ends of forward beam 10 when terminal, last forward beam 10 maintains static with drill bar 8, we just can regard last forward beam 10 and drill bar 8 as an integral body, chain drive work like this, forward beam 10 begins action thereby chain 7 pulling drill bars 8 drive upward.
What need understand is: though the foregoing description is to the utility model detailed explanation of contrasting; but these explanations; just to simple declaration of the present utility model; rather than to restriction of the present utility model; any utility model that does not exceed in the utility model connotation is created, and all falls in the protection domain of the present utility model.
