Horizontal directional drilling machine drilling stand capable of being conveniently assembled

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 [0001] The invention relates to a drill frame of a horizontal directional drilling machine which can be easily assembled, in particular to a segmented, quick-connected thin-walled box-type drill frame structure. Background technique [0002] Now horizontal directional drilling rigs usually adopt integral structure. In large directional drilling rigs, the weight of the drilling rig is relatively large, and the length generally exceeds 17 meters. The supply length of high-strength steel plates in my country is less than 10 meters. The steel plate splicing is required when the directional drilling rig drills the frame, which will have a certain impact on the strength of the drill frame. The length of the drill stand is too long, which increases the processing and transportation costs. In addition, the rack is welded on the drill stand, which requires high welding precision, and it is difficult to replace the rack after it is damaged. Contents of the invention ...
