The specific embodiment
Fig. 2 is the schematic diagram of adjustable height support roller device of the present utility model, as shown in the figure, adjustable height support roller device of the present utility model comprises Height Adjustment oil cylinder 10, carrying roller 30 and roller rack 20, carrying roller 30 is installed on the roller rack 20, roller rack 20 is installed on the shoulder of piston rod 102 of Height Adjustment oil cylinder 10, and fastening with nut.
Fig. 3 is the schematic diagram of Height Adjustment oil cylinder among Fig. 2, as shown in the figure, Height Adjustment oil cylinder 10 comprises: base plate 100, cylinder barrel 101, piston rod 102, adjustment screw rod 103, stop nut 104, linking bond 106, height adjusting link 107, axle sleeve 110, pinion 108 and gear wheel 109; Described cylinder barrel 101 is fixed on the base plate 100 by screw; One end of described adjustment screw rod 103 is positioned at piston rod 102 inside, and axle sleeve 110 is threaded with piston rod 102.
Stop nut 104 and adjustment screw rod 103 are threaded, and linking bond 106 places between stop nut 103 and the piston rod 102, referring to the matching relationship schematic diagram between piston rod shown in Figure 4 102, adjustment screw rod 103, stop nut 104 and the linking bond.Linking bond 106 can prevent that stop nut 103 from following and adjust screw rod 103 and rotate, and stop nut 106 moves up and down in piston rod 102 keyways when adjusting screw rod 103 when rotating, thereby can set stop nut 106 in the position of adjusting on the screw rod 103.Stop nut 106 is exactly the stroke of piston rod 102 with the distance of the bottom axle sleeve 110 of piston rod 102, promptly promotes the distance that drilling rod rises.But the stroke of axle sleeve 110 limited piston bars 102.
Above adjusting screw rod 103 spindle noses, made a upper limit position block 105 simultaneously, limited block 105 is enclosed within to be adjusted on the screw rod spindle nose, be stuck on the spindle nose of adjusting screw rod 103 with a jump ring, prevent with this fixed upper limit position piece 105 that stop nut 104 from escaping from when the adjusted and adjust screw rod 103.Upper limit position block 105 also can be fixed on by the mode that is threaded to be adjusted on screw rod 103 spindle noses.
Adjust screw rod 103 lower ends and be connected with gear wheel 109, the lower end of height adjusting link 107 is connected with pinion 108, pinion 108 and gear wheel 109 engagements.Being connected between the lower end of adjusting screw rod 103 lower ends and gear wheel 109 and height adjusting link 107 and the pinion 108 can be adopted the key connection.The lower end of height adjusting link 107 is installed together height adjusting link 107 and base plate 100 by the hole tight fit of bearing and base plate 100.
Fig. 5 is the schematic diagram that adjustable height support roller device of the present utility model is used to adjust the drilling rod height, and wherein (a) is for before adjusting, (b) for after adjusting.Shown in Fig. 5 (a), before adjustment, drilling rod 3 centers are that the alignment of shafts has a segment distance to chuck 4 centers.If this distance is 100mm, and stop nut 104 is at the top of adjusting screw rod 103, and the distance that stop nut 104 and axle sleeve are 110 is that the range of piston rod 102 is 210mm, is 100mm with regard to the distance that must adjust 110 on stop nut 104 and axle sleeve like this.The distance of promptly adjusting 110 on stop nut 104 and axle sleeve is the distances of drilling rod 3 centers to chuck 4 centers.At this moment rotatable height adjusting link 107, drive gear wheel 109 rotations by pinion 108, gear wheel 109 drives again adjusts screw rod 103 rotations, thereby driving stop nut 104 vertically moves downward, after adjusting the position of stop nut 104, piston rod 102 is moved up up to axle sleeve 110 and stop nut 104 end faces by extremely stopping, finishing the state shown in Fig. 5 (b) thereby adjust.This moment, drilling rod 3 centers were that the alignment of shafts overlaps to chuck 4 centers.
The distance that stop nut 104 is adjusted and the pitch of the gear ratio of crossing pinion 108 and gear wheel 109, adjustment screw rod 103 and the relating to parameters such as the number of turns that rotate height adjusting link 107.Therefore will adjust certain distance, the rotation number of turns are just passable accordingly only need to be converted into height adjusting link 107.
