Abstract
The invention discloses a horizontal directional drilling machine drilling stand capable of being conveniently assembled. The horizontal directional drilling machine drilling stand capable of being conveniently assembled comprises three drilling stand bodies, a power head is arranged on a second drilling stand body, a first drilling stand body and a third drilling stand body are connected at two ends of the second drilling stand body respectively, first pin shaft bases are connected with second pin shaft bases through first pin shafts, a first support, second supports and a first support are arranged on the three drilling stand bodies respectively, the two supports on the second drilling stand body are connected with the folded first drilling stand body and the folded third drilling stand body through second pin shafts, a first limiting mouth end face is matched with a second limiting mouth end face, and functions of quick locating and shear force reduction of bolts are achieved. A rack is connected with a vertical plate through the bolts to facilitate disassembling and replacement of the rack, steel plates do not need to be spliced when the drilling stand is welded, machining cost and transport cost are reduced, and quick mounting and locating can be carried out. Shear force borne by the connecting bolts is reduced, twisting resistance capacity of the drilling stand is improved, the rack can be convenient to replace, and meanwhile a thin-walled box type reinforcing bar structure also reduces the weight of the drilling stand.
Description
Technical field
The present invention relates to a kind of drilling cramp of horizontal directional drilling machine that can light assembling, relate in particular to a kind of segmented, connect thin-walled box drilling cramp structure soon.
Background technology
The horizontal directional drill quarry bar adopts all-in-one-piece structure usually now, in large-scale directional drilling machine, the weight of drilling cramp is bigger, length generally all surpasses 17 meters, the supply of material length of China's high-strength steel sheet is below 10 meters, need the steel plate splicing like this when machining large directional drilling machine drilling cramp, 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 the drilling cramp in addition, needs very high welding precision, and tooth bar damages, and the back is very difficult to be changed.
Summary of the invention
In order to overcome above-mentioned defective, the invention 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 the travel position drilling cramp in working order, tooth bar can be convenient for changing after damaging, and reduces maintenance cost.
The present invention 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, described drilling cramp two is provided with unit head, described drilling cramp one and drilling cramp three are movably connected in the two ends of drilling cramp two respectively, and pass through bearing pin one with drilling cramp one, axis pin base one on the drilling cramp three is connected with axis pin base two on the drilling cramp two, described drilling cramp one, be respectively arranged with bearing one on drilling cramp two and the drilling cramp three, bearing two and bearing one, and two bearings two on the drilling cramp two respectively with folding after drilling cramp one and drilling cramp three between be connected by bearing pin two, seam end face one on described drilling cramp one and the drilling cramp three matches with the seam end face two on the drilling cramp two, described tooth bar by bolt be welded in drilling cramp one, drilling cramp two, riser on the 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 structure 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, and is 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 invention has the beneficial effects as follows: described drilling cramp structure adopts thin-walled box reinforced structure, has reduced the weight of drilling cramp; Drilling cramp is divided into three parts, and every part is all below 9 meters, and steel plate need not splice when the welding drilling cramp, has reduced processing and cost of transportation, and in working order with travel position in drilling cramp can the 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 adopts bolt to be connected with drilling cramp, can change easily after tooth bar damages.
