Technical field
The utility model relates to a kind of drilling cramp of horizontal directional drilling machine that can light assembling, relates in particular to a kind of segmented, connects thin-walled box drilling cramp structure soon.
Background technology
Horizontal directional drill quarry bar adopts all-in-one-piece structure conventionally now, in large-scale directional drilling machine, the weight of drilling cramp is larger, length generally all surpasses 17 meters, the supply of material length of China's high-strength steel sheet is below 10 meters, when machining large directional drilling machine drilling cramp, need like this steel plate splicing, this can have certain influence to the intensity of drilling cramp.Drilling cramp length is long, has increased processing and cost of transportation.Tooth bar is welded on drilling cramp in addition, needs very high welding precision, and tooth bar damages the rear replacing that is difficult to.
Summary of the invention
In order to overcome above-mentioned defect, the utility model provides a kind of drilling cramp of horizontal directional drilling machine that can light assembling, this structure can reduce the weight of drilling cramp, make processing and transport convenient, and can assemble fast with travel position drilling cramp in working order, tooth bar can be convenient for changing after damaging, and reduces maintenance cost.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of drilling cramp of horizontal directional drilling machine that can light assembling, comprise drilling cramp one, drilling cramp two and drilling cramp three, on described drilling cramp two, be provided with unit head, described drilling cramp one and drilling cramp three are movably connected in respectively the two ends of drilling cramp two, and pass through bearing pin one by drilling cramp one, axis pin base one on drilling cramp three is connected with the axis pin base two on drilling cramp two, described drilling cramp one, on drilling cramp two and drilling cramp three, be respectively arranged with bearing one, bearing two and bearing one, and two bearings two on drilling cramp two respectively with folding after drilling cramp one and drilling cramp three between by bearing pin two, be connected, described drilling cramp one matches with the seam end face two on drilling cramp two with the seam end face one on drilling cramp three, tooth bar is by bolt and be welded in drilling cramp one, drilling cramp two, riser on drilling cramp three connects.
Described drilling cramp one, drilling cramp three are provided with keyway with the contact surface of drilling cramp two.
What described drilling cramp one, drilling cramp two and drilling cramp three all adopted is thin-walled box reinforced structure, and thin-walled box reinforced structure has alleviated the weight of drilling cramp integral body on the one hand, also more firm on the other hand.
Described drilling cramp one, drilling cramp three are folding or to homonymy is folding to the same side with respect to drilling cramp two.
The beneficial effects of the utility model are: described drilling cramp structure adopts thin-walled box reinforced structure, have reduced the weight of drilling cramp; Drilling cramp is divided into three parts, and every part is all below 9 meters, and when welding drilling cramp, steel plate need not splice, and has reduced processing and cost of transportation, and in working order with travel position in drilling cramp can Fast Installation location; By at drilling cramp contact end face, end face seam and keyway being set, reduced the shearing force that connecting bolt bears, increased the anti-torsion ability of drilling cramp; Tooth bar and drilling cramp are with bolts, after tooth bar damages, can change easily.
