Abstract
A reverse circulation drill belongs to drill irrigation pile construction plant technical field, which comprises an active disc connected with power supply, wherein the active disc is connected with a hollow active drill rod which lower end is arranged with a drill head and upper end is sheathed with the chamber of cock, and lower end is connected with the drill head with a slag channel, the hollow drill rod is connected with a mud pump connected with a power device on the cock via a connecting shaft, the cock is arranged with a slag outlet, the upper end of the active drill rod and the chamber of cock are connected via an axle sheath or a bearing, the upper opening of the mud pump is fixed with the active drill rod, while lower opening is fixed with the drill rod, the lower drill rod is composed of multiple sections of drill rods, and the active disc is connected with power supply via a meshed gear. The power supply is a speed-reduction motor. The utility model has few devices, simple structure, less maintenance, high drill efficiency and little hole inclination.
Description
Technical field
The utility model belongs to the bored pile construction equipment technical field, particularly a kind of bore operation clean-out machine.
Background technology
In bored pile construction, need to use a cover rig and a cover body refuse or a mud extracting device.Mode according to mud and body refuse turnover institute well bore can be divided into two kinds of circulation drill system and clean-out machine systems.In circulation drill system job process, the other set mud pit mouth of institute's well bore is lower than the wellhole mouth, and the body refuse gravity flow that produces in the drilling process enters mud pit, and through post precipitation, mud pit upper strata mud is squeezed in the wellhole by the outer set slush pump of well; And in clean-out machine system job process, the other set mud pit mouth of institute's well bore is higher than the wellhole mouth, and the body refuse that produces in the drilling process is by the set sand pump suction of bottom mud pit, and through post precipitation, mud gravity flow in mud pit upper strata enters in the wellhole.There are two types of pump suction type and gaslift formulas in existing clean-out machine system, pump suction type clean-out machine system comprises two kinds again, the centrifugal sand pump that the outer land of wellhole is located in first utilization extracts the body refuse in the wellhole bed mud slurry, and it two is to utilize the sand pump of being located at borehole bottom to extract body refuse in the mud at the bottom of the wellhole.Gaslift formula clean-out machine system utilizes the air compressor machine of being located at the outer land of well by the body refuse in the negative pressure extracting wellhole bed mud slurry.The existing positive and negative circulating system all adopts the drill bit of hollow kelly and band silt particle passage.Above-mentioned borer system equipment needed thereby is many, complex structure; Sand pump slips into operation in the wellhole bed mud slurry, and seal is easy to wear; Sand pump is located at the outer operation of wellhole and is leaked easily; Use air compressor machine then strict, gas leakage easily in the construction to system's tightness.
The utility model content
The utility model purpose is to provide a kind of clean-out machine simple in structure
For reaching above-mentioned purpose, the utility model adopts following technical scheme: a kind of clean-out machine, comprise the active rotating disk that links to each other with power, initiatively rotating disk connects with the hollow kelly, the drilling rod lower end is equipped with drill bit, and the kelly upper end is connected with the drill bit of band body refuse passage with the socket of water tap inner chamber, lower end, is connected with sand pump on the hollow drill, the power set that sand pump is installed above by coupling spindle and water tap link, and water tap is provided with sludge outlet.
Kelly connects by axle sleeve or bearing with the water tap inner chamber; Sand pump is suitable for reading fixedlys connected with kelly, end opening is fixedlyed connected with the drilling rod that is connected with drill bit, and the hypomere drilling rod can be formed by connecting by the more piece drilling rod; Initiatively rotating disk is by linking with its meshed gears and power.
Described power is reducing motor.
The utility model kelly adopts hollow-core construction, its lower end connects and has the body refuse admission passage on the drill bit, its upper end is communicated with sludge outlet by water tap, in the work progress, take out under the act effect at sand pump, body refuse in the wellhole bed mud slurry enters hollow drill by the body refuse passage on the drill bit, and then the discharge of the sludge outlet above water tap enters mud pit.The utility model only needs a set of equipment can finish boring and extracts two operations of body refuse, and the prior art equipment needed thereby is few relatively, and cost is low, and is simple in structure; Hypomere drilling rod between sand pump and the drill bit can be made of (when just boring down) a joint, also can be by some joints be formed by connecting (after creeping into certain depth), therefore sand pump can be under the well head place mud face all the time, and needn't be located in the body refuse at the bottom of the wellhole, body refuse can be smoked by passage on the drill bit and drilling rod inner chamber, thereby institute is frayed few, and plant maintenance workload and maintenance cost reduce, and service life of equipment prolongs; Because wellhole subdrilling slag remains less state, the drill bit resistance is little, and drilling efficiency is higher, and the hole deviation that forms during boring is less.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Embodiment, a kind of clean-out machine comprise the active rotating disk 2 by linking to each other with reducing motor with its meshed gears, and initiatively rotating disk connects with hollow kelly 1, connect by axle sleeve with water tap 8 inner chambers on the kelly.Sand pump 3 is suitable for reading fixedlys connected with the kelly outer wall, end opening is fixedlyed connected with the hollow drilling rod 12 that is connected with drill bit 4, and the hypomere drilling rod can be formed by connecting by the more piece drilling rod.The reducing motor 6 that sand pump is installed above by coupling spindle 5 and water tap links, and water tap is provided with sludge outlet 7.9 is rig upper casing frame, and 13 is the sand pump impeller.10 is well head, and 11 is the basis.
