A inner tooth section and a tooth strip are arranged inside the first section of the drilling rod, a flange rib plate is arranged on the top end of the first section of the drilling rod, tooth strips are arranged inside the N sections of the drilling rod in the middle, upper connectors of the drilling rod are welded on the top ends of the N sections of the drilling rod in the middle, a water discharge plate, a crash bearing plate and a square head are arranged from top to bottom on the bottom end of the rear section of the drilling rod, the upper end of the square head is provided with a gap ring, a blocking board is arranged above the gap ring, a movable ring is arranged on the upper end of the N sections of the drilling rods in the middle and the lower portion of the upper connectors of the drilling rod, the movable ring is embedded on the connecting position of the upper connectors of the drilling rod and the N sections of the drilling rods, and adding of the movable ring is capable of effectively avoiding the connectors on the drilling rod in the middle bearing impacts directly, and due to own characteristics of the movable ring, the movable ring is enabled to bear friction and impact force for a long time, and therefore service life of the middle drilling rod and the rotary drilling rig are prolonged.
Description
Technical field
The utility model relates to a kind of drilling machine drilling rod with movable wear ring, belongs to technical field of engineering machinery.
Background technology
Rotary drilling rig is the construction machinery of pore-forming operation in a kind of suitable building foundation engineering.Mainly be suitable for the soil layer constructions such as sand, cohesive soil, slity soil, in the multiple foundation basic constructions such as castinplace pile, diaphragm wall, underpin, be used widely, rotary drill rod is the important component part of rotary drilling rig, and the quality of its service behaviour is directly connected to the duty of rotary drilling rig.
Drilling machine drilling rod is generally more piece and is embedded in together use, comprises first segment drilling rod, intermediate drill and minor details drilling rod.During rod boring, more piece drilling rod ecto-entad stretches out successively and creeps into, when drilling rod promotes, reversed in order promotes from inside to outside successively, therefore at present, in the drilling rod course of work, middle more piece drilling rod is under the enormous impact power that telescopic action brings, and frictional force and impact are constantly born in its top connection, is easy to wearing and tearing, in case top connection damages, whole joint drilling rod has just been scrapped, and not only causes the waste of resource, and affects the progress of digging of revolving of rotary drilling rig.
Summary of the invention
Problem for above-mentioned prior art existence, the utility model provides a kind of drilling machine drilling rod with movable wear ring, bump is directly born in the top connection of N joint drilling rod in the middle of can effectively avoiding, and the rotating characteristics of loose collar itself, so that loose collar can bear frictional force and impact for a long time, and then prolong the application life that middle N saves drilling rod and rotary drilling rig.
To achieve these goals, the technical solution adopted in the utility model is: a kind of drilling machine drilling rod with movable wear ring, comprise the first segment drilling rod, middle N joint drilling rod and minor details drilling rod, interior tooth section and gear rack are arranged in the first segment drilling rod, its top is the flange gusset, in the middle N joint drilling rod gear rack is arranged, the top is welded with the drilling rod top connection, minor details drilling rod bottom is provided with the dish that discharges water from top to bottom successively, hold and hit dish and square toes, the upper end of square toes is provided with to hold hits dish, hold and hit dish and be provided with spring guiding between the dish with discharging water, the spring guiding outside is overlapped spring is arranged, and minor details drilling rod top is provided with landolsring, the top of landolsring is provided with baffle plate, baffle plate is connected with ear stud, the upper end of middle N joint drilling rod, there is a loose collar below of drilling rod top connection, is nested in the connector place of drilling rod top connection and middle N joint drilling rod.
Loose collar is rotatable, and be wear-resistant material, mobilizable characteristics, so that this ring whenever is subjected to one-shot, all can rotate, so can avoid local fixing stressed, greatly prolonged the application life of loose collar, select wear-resistant material, especially can the extender useful life, and then prolong application life of drilling rod and rotary drilling rig.
Because the increase of loose collar in this device, therefore compared with prior art, frictional force that drilling rod work telescopic action brings and huge impact have been avoided bearing between the top connection of middle N joint drilling rod, and loose collar is rotatable, so ring can be local fixing not stressed, therefore can use for a long time, and then reduced the scrappage of drilling rod, prolong its application life, reduced the cost of production of rotary drilling rig, and guaranteed the excavation progress.

Fig. 2 is N joint jackrod structure schematic diagram in the middle of the utility model;
Fig. 3 is the utility model minor details jackrod structure schematic diagram.
Among the figure: 1, interior tooth section, 2, the first segment drilling rod, 3, gear rack, 4, flange gusset, 5, middle N saves drilling rod, 6, loose collar, 7, drilling rod top connection, 8, the minor details drilling rod, 9, hanger, 10, baffle plate, 11, landolsring, 12, dish discharges water, 13, spring guiding, 14, spring, 15, hold and hit dish, 16, square toes.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1 to Figure 3, the drilling machine drilling rod of the movable wear ring of this band, comprise first segment drilling rod 2, middle N joint drilling rod 5 and minor details drilling rod 8, interior tooth section 1 and gear rack 3 are arranged in the first segment drilling rod 2, its top is flange gusset 4, in the middle N joint drilling rod 5 gear rack 3 is arranged, the top is welded with drilling rod top connection 7, minor details drilling rod 8 bottoms are provided with the dish 12 that discharges water from top to bottom successively, hold and hit dish 15 and square toes 16, the upper end of square toes 16 is provided with to hold hits dish 15, hold and hit dish 15 and be provided with spring guiding 13 between 12 with the dish that discharges water, spring 13 outsides of leading are overlapped spring 14 are arranged, and minor details drilling rod 8 tops are provided with landolsring 11, the top of landolsring 11 is provided with baffle plate 10, baffle plate 10 is connected with hanger 9 bolts, the upper end of middle N joint drilling rod 5, there is a loose collar 6 below of drilling rod top connection 7, is nested in the connector place of drilling rod top connection 7 and middle N joint drilling rod 5.
To have four to save the rotary drilling rig of middle node drilling rods as example, during use, press diameter from small to large, six joint drilling rods are embedded in together from inside to outside successively, and during rotary drilling rig work, unit head drives first segment drilling rod 2, first segment drilling rod 2 promotes, the top of N joint drilling rod is subject to the impact force that it brings in the middle of the first segment, and the rotating ring 6 that is positioned at drilling rod top connection 7 belows alive stood in the breach and bore this bump this moment, had protected drilling rod top connection 7; When first segment drilling rod 2 stretches out in a flash.Under the effect of inertia, it rotates by driving rotating ring 6, and the more serious position that is hit has then probably forwarded the position of other impact less to, waits for that next first segment drilling rod 2 promotes the impact of bringing; The first segment drilling rod of N joint drilling rod 5 brings impact can for when promoting the second section drilling rod of middle N joint drilling rod 5 simultaneously, loose collar 6 in the middle of this moment on the second section drilling rod of N joint drilling rod 5 can play same effect, by that analogy, with the work of rotary drilling rig, loose collar 6 is with the flexible iterative cycles work of drilling rod.
The drilling rod joint number is all applicable more than or equal to three joints.
