The operational stability of rotary drilling rig used at present is to be improved, influences the quality and efficiency of processing, while drill bit It is easily damaged, service life is short, increases cost.
Utility model content
The utility model provides a kind of rotary drilling rig, and reasonable design, operational stability is high and extends the service life of drill bit, Reduce cost and safe.
The utility model is achieved through the following technical solutions, a kind of rotary drilling rig, including creeper undercarriage, described Creeper undercarriage is equipped with hydraulic system and operation chamber system, and one end of the hydraulic system passes through hydraulic arm group mechanism and support Bar is connected and fixed;One end of the strut is equipped with paying out machine;The steel wire rope of the wherein described paying out machine successively pass through actinobacillus wheel with it is convex Bar is connected and fixed;One end of the wherein described nose bar is connected and fixed with drill string is dug;The digging drill string is equipped with several clamp rings;Wherein The lower end for digging drill string is connected and fixed by whirler with drill tool assembly is dug;The digging drill tool assembly includes from top to bottom successively Drilling rod, connecting pole and the drill bit of setting;Hydraulic arm group mechanism includes the first hydraulic stem and connecting lining plate;The connecting lining plate Top be connected and fixed by the first hydraulic stem and the strut.
It is as further improvement of the utility model:It is slided with the sliding rail on the strut at the both ends of each clamp ring Dynamic connection.
It is as further improvement of the utility model:It is connected and fixed by connecting rod and shield on the drilling rod, Anti-spattering function can be played when operation.
It is as further improvement of the utility model:The drill bit is equipped with the block of resistance to roll flute, improves tear resistance.
When the utility model operates:It is smoothly walked on-site by creeper undercarriage, staff is in operating room Operation operating system is inside carried out, and hydraulic arm group mechanism is worked by hydraulic system, the work of the first hydraulic stem makes connection Strut on liner plate moves upwards, and paying out machine work makes steel wire rope that digging drill string be driven to move downward, and clamp ring slides on sliding rail, It is the stationarity for ensureing to dig drillstring motion, then whirler, which drives, digs drill tool assembly rotation, and connecting pole is made to coordinate drill bit to ground Carry out rotation borehole.
The utility model has the beneficial effects that:Reasonable design, operational stability is high and extends the service life of drill bit, reduces Cost and safe.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model embodiment;
Wherein 1- creepers undercarriage, 2- hydraulic systems, 3- operation chamber system, 4- struts, 5- paying out machines, 6- actinobacillus wheels, 7- nose bars, 8- dig drill string, 9- clamp rings, 10- whirlers, 11- drilling rods, 12- connecting poles, 13- drill bits, the first hydraulic stems of 14-, 15- Connecting lining plate, 16- sliding rails, 17- connecting rods, 18- shields, the 19- blocks of resistance to roll flute.
Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings:
As shown in Figure 1:A kind of rotary drilling rig of the present embodiment, including creeper undercarriage 1, the creeper undercarriage 1 It is equipped with hydraulic system 2 and operation chamber system 3, one end of the hydraulic system 2 is connect by hydraulic arm group mechanism with strut 4 admittedly It is fixed;One end of the strut 4 is equipped with paying out machine 5;Wherein the steel wire rope of the paying out machine 5 passes through actinobacillus wheel 6 and connects with nose bar 7 successively Connect fixation;Wherein one end of the nose bar 7 is connected and fixed with drill string 8 is dug;The digging drill string 8 is equipped with several clamp rings 9;Each The both ends of the clamp ring 9 are slidably connected with the sliding rail 16 on the strut 4.
The wherein described lower end for digging drill string 8 is connected and fixed by whirler 10 with drill tool assembly is dug;The digging drill tool assembly Including the drilling rod 11, connecting pole 12 and drill bit 13 set gradually from top to bottom;The drill bit 13 is equipped with the block of resistance to roll flute 19, described It is connected and fixed by connecting rod 17 and shield 18 on drilling rod 11.
Hydraulic arm group mechanism includes the first hydraulic stem 14 and connecting lining plate 15;The top of the connecting lining plate 15 passes through First hydraulic stem 14 is connected and fixed with the strut 4.
When the present embodiment operates:By creeper undercarriage 1, smoothly walking, staff enter operating room on-site It is operated in system 3, and hydraulic arm group mechanism is worked by hydraulic system 2, the work of the first hydraulic stem 14 makes connection Strut 4 on liner plate 15 moves upwards, and paying out machine 5 works, and makes steel wire rope that digging drill string 8 be driven to move downward, clamp ring 9 is in sliding rail 16 Upper sliding, is to ensure to dig the stationarity that drill string 8 moves, and then whirler 10, which drives, digs drill tool assembly rotation, and connecting pole 12 is made to match Bench drill head 13 carries out rotation borehole to ground.
The advantageous effect of the present embodiment is:Reasonable design, operational stability is high and extends the service life of drill bit, reduce at Originally and it is safe.
