Abstract
The utility model relates to drilling machine field, and the purpose of this utility model is to provide a kind of pipe piercing machine.This drilling machine comprises centre drill, drilling rod, panel nut, bolt, and the middle part of described centre drill is provided with external screw thread, and panel nut is provided with internal thread, through hole, and drilling rod is provided with internal thread hole; Panel nut is connected with the external screw thread in the middle part of centre drill by internal thread, and is connected with the internal thread hole that drilling rod is arranged with the through hole of bolt through panel nut.The utility model compared with prior art, effectively prevent the centre drill when drilling rod reverses to come off from drilling rod and fall into machine chamber, detaching equipment is needed to reinstall the phenomenons such as centre drill, and by rotary pressure plate nut, centre drill can be extracted in drilling rod when dismantling centre drill, thus effectively reduce production cost, improve the efficiency of construction operation.
Description
Technical field
The utility model relates to drilling machine field, refers more particularly to a kind of pipe piercing machine.
Background technology
In modern city civilian infrastructure is built, conveying main pipeline all needs grafting lateral, and during construction, pipeline needs boring.In prior art, because drill bit and drilling rod are directly threaded connection, once misoperation causes drilling rod to reverse, drill bit falls into machine chamber because the principle of spiral can depart from drilling rod immediately, need equipment dismounting to reinstall centre drill, not dawn impact construction, and damage rig.
Utility model content
The purpose of this utility model to be connected for the centre drill of existing pipe piercing machine the defect and problem that exist with drilling rod, proposes a kind of pipe piercing machine.
It comprises centre drill, drilling rod, panel nut, bolt, and the middle part of described centre drill is provided with external screw thread, and panel nut is provided with internal thread, through hole, and drilling rod is provided with internal thread hole; Panel nut is connected with the external screw thread in the middle part of centre drill by internal thread, and is connected with the internal thread hole that drilling rod is arranged with the through hole of bolt through panel nut.
Further, the quantity of the internal thread on described drilling rod is the twice of the quantity of the through hole in panel nut.
Further, described panel nut is provided with boss in the side to drilling rod.
Further, when described panel nut is installed and the gap of drilling rod should be greater than 2mm.
Further, the through hole of described panel nut is annular slotted hole.
The utility model to the connection of centre drill and drilling rod except himself Morse's taper is closely connected, the reinforcement additionally using panel nut and bolt is fixedly connected with, compared with prior art, the center when drilling rod reverses that effectively prevent turns to come off from drilling rod falls into machine chamber, detaching equipment is needed to reinstall the phenomenons such as centre drill, and by rotary pressure plate nut, centre drill can be extracted in drilling rod when dismantling centre drill, thus effectively reduce production cost, improve the efficiency of construction operation.

Description of reference numerals: 1 centre drill, 2 drilling rods, 3 panel nut, 4 bolts, 5 external screw threads, 6 internal threads, 7 through holes, 8 internal thread holes, 9 boss, 10 annular slotted holes.
Detailed description of the invention
Be described in detail below with reference to the enforcement of accompanying drawing to the technical solution of the utility model, so that those skilled in the art understand better and implement.
As accompanying drawing 1, as shown in Figure 2, this drilling machine comprises centre drill 1, drilling rod 2, panel nut 3, bolt 4, and the middle part of described centre drill 1 is provided with external screw thread 5, and panel nut 3 is provided with internal thread 6, through hole 7, drilling rod 2 is provided with internal thread hole 8; Panel nut 3 is connected with the external screw thread 5 in the middle part of centre drill 1 by internal thread 6, and with bolt 4 through panel nut 3 through hole 7 with drilling rod 2 is provided with internal thread hole 8 and is connected.
More optimize, the quantity of the internal thread hole 8 on described drilling rod 2 is twices of the quantity of the through hole 7 in panel nut 3, can be installed on drilling rod 2 arbitrarily angled to realize panel nut 3.
More optimize, described panel nut 3 is being provided with boss 9 to the side of drilling rod 2, to realize when centre drill 1 ejects by rotary pressure plate nut 3, reduces the contact surface of panel nut 3 and drilling rod 2, more laborsaving during to realize dismantling centre drill 1.
More optimize, when mounting center bores 1, ensure that panel nut 3 should be greater than 2 millimeters, to realize the fixing booster action of panel nut 3 pairs of centre drills 1 better with the gap of drilling rod 2.
As shown in Figure 3, the through hole (7) of described panel nut (3) is more annular slotted hole (10), can be installed on drilling rod 2 arbitrarily angled to realize panel nut 3.
The utility model have employed panel nut and the connection of bolt to centre drill and drilling rod has been carried out strengthening fixing, compared with prior art, the center when drilling rod reverses that effectively prevent turns to come off from drilling rod falls into machine chamber, detaching equipment is needed to reinstall the phenomenons such as centre drill, and by rotary pressure plate nut, centre drill can be extracted in drilling rod when dismantling centre drill, thus effectively reduce production cost, improve the efficiency of construction operation.
