The high speed rotary rig
Technical field
The utility model relates to a kind of plant equipment, particularly a kind of high speed rotary rig.
Background technology
The overwhelming majority adopts the deposited reinforced concrete pile pile foundation on the basis of buildings such as bridge, house, harbour.The deposited reinforced concrete pile pile foundation is divided into end bearing pile and friction pile; And the drilling construction of pile foundation; Main technology type has rotary drilling rig drilling construction, the construction of abrasion drill machine drill hole and punching rig drilling construction; Preceding two kinds of technologies are applicable to friction pile, and a kind of technology in back is applicable to end bearing pile, and there is following shortcoming in existing rotary drilling rig drill construction technique: 1, equipment cost is high; 2, construction cost high (brute force is revolved and dug, and comes back cutting to unload, highly energy-consuming); 3, construction depth limited (generally the darkest 65 meters); 4, hole wall irregularity (bucket is twitched up and down, due to mud does not stop to wash away to hole wall) behind the pore-forming; 5, waste material (causing reaming and then increase using concrete) because of hole wall washes away; 6, self hole clearly, be difficult to by the direct circulation bath dregs at the bottom of the hole is clean clearly, 7, noise pollution is serious.
There is following shortcoming in the existing rig construction technology of circling round: 1, speed of application is slow, is out of step with modern architecture; 2, the anti-circulating water pump work of rig of circling round; Therefore 1 ~ 4 meter suction journey must be arranged, inhale in the journey scope highly to seal request, but that the drilling rod that circles round is not stall is moving; And flowing to the outlet pipe of mud pit, the drilling rod top can't rotate thereupon; Also can't overcome the high-seal problem fully with present level, therefore, in rig when work, often be compelled interruption of work because of sealing gas leakage; 3, drilling depth is limited, and after boring reached certain depth, pump sump was because of overload quit work (because of mud strengthens the also corresponding increasing of proportion with hole depth); 4, water pump suction can not infinitely strengthen, and when water pump suction (power) is increased to a certain degree, cobble that is mingled with in the soil body of boring or slabstone can smash water pump; 5, construction environment is required height,, therefore, often be difficult to adapt to because bridge pile foundation is the design of suiting measures to local conditions.
The utility model content
The technical problem that the utility model will solve is to overcome existing technical deficiency, and a kind of reduction equipment cost, construction cost and energy loss are provided; Can prolong construction depth, significantly improve penetration rate, improve hole quality; And action is convenient, adaptable high speed rotary rig.
The utility model is achieved in that a kind of high speed rotary rig; Comprise endless track installation, mast mounting system, drilling rod system and bit system; Said endless track installation is connected the mast mounting system through support bar with jack, mast mounting system jointed rod system and bit system, and the drilling rod system lock connects bit system; It is characterized in that: said bit system comprises water pump, power set and drill bit; Power set are installed in the top of drill bit, and water pump is installed on the power set, and hydraulic tube is connected to drill bit from the hydraulic tube reel on the mast mounting system.
Said bit system also comprises a breaker, and breaker is located at bit central, and the conduit under fluid pressure of breaker inserts in the water service pipe of drilling rod system.
Said mast mounting system bottom is equipped with jack, and an i iron is withstood in the bottom of jack.
The drilling rod of said drilling rod system is linked together through screw thread or flange by some isometric hollow steel pipes.
Said water pump is a hydraulic pump, and it is made up of hydraulic motor and impeller pump.
Said power set are made up of hydraulic motor and reduction box.
The advantage of the utility model is: whole workflow is the work of the anti-circulation rotary drilling of high speed; What adopt all is skilful power; Scientific and effective, the horsepower of endless track installation can be littler by 40% than Spiral digging machine, and the comparable Spiral digging machine of mast height (length) is short; Reduce equipment cost, construction cost and energy loss greatly, prolong construction depth simultaneously; Water pump changes to hydraulic pump and is installed on the drill bit, underwater operation, and changing the suction journey is lift, and water circulation efficient is significantly improved, penetration rate significantly improves; Bit central is established breaker, and cobble in the soil layer, little rock ballast, slabstone stop up circulating water pipeline when having solved construction, and the danger of also having avoided smashing water pump reduces fault rate; The pore-forming hole wall is avoided current scour, improves hole quality, makes at the bottom of the hole totally, and hole wall is regular, and economical with materials reduces noise significantly, and action is convenient, and compliance is strong.
Description of drawings
Combine embodiment that the utility model is further described with reference to the accompanying drawings.
Fig. 1 is the overall structure sketch map of the high speed rotary rig of the utility model.
The specific embodiment
See also Fig. 1; It is the overall structure sketch map of the high speed rotary rig of the utility model; A kind of high speed rotary rig comprises endless track installation 1, mast mounting system 2, drilling rod system 3 and bit system 4, and said endless track installation 1 is through support bar 11 and jack 12 connection mast mounting systems 2; The lifting of mast mounting system 2 control drilling rod systems 3 and bit system 4,3 lockings of drilling rod system connect bit system 4.
Endless track installation 1 adopts the hydraulic pressure fuel feeding, and power is big, and walking is convenient, and main effect is power source, support and the walking as rig; Mast mounting system 2 is used for lifting and control the hoisting operation of drilling rod, drill bit, conduit under fluid pressure reel 21 is installed on the mast mounting system 2 is used to connect drill bit, hydraulic winch is installed so that drilling rod to be installed; Be used for hanging drilling rod, drill bit creeps into or tear brill open, mounting and fixing bracket pins drilling rod, plays fixing and guide effect; Drilling rod is only slided up and down do not rotate, jack 5 is installed in mast mounting system 2 bottoms, horizontal on the ground i iron 6; Jack 5 withstands i iron 6; Make mast more stable, do not vacillate, guarantee that a hole hole wall is vertical, smooth-going to guarantee rig when work rig; The hollow drill of drilling rod system 3 is linked together through screw thread or flange by some isometric hollow steel pipes; Drilling rod system 3 connects locking bit system 4; It is the support of drill bit rotary operation; Also be the support that the drill bit pressurization is crept into or promoted, hollow drill is again the ventilating water pipe of the anti-cycle operation of mud both as the fixed support of drill bit; Bit system 4 comprises water pump 41, power set 42, drill bit 43 and breaker 44; It adopts hydraulic-driven; Power set 42 are installed in the top of drill bit 43; Water pump 41 is installed on the power set 42, and breaker 44 is located at drill bit 43 centers, and the conduit under fluid pressure of breaker 44 inserts in the water service pipe of drilling rod system 3.
