Abstract

The present invention belongs to a well drilling (hole forming on foundation piles) machine which comprises a suspending and detaching machine 2, a speed changing box 11, a rotary disk 13, a hollow rod 14, a drill bit 15, a slurry pump 16, a punching and grabbing conical head 18, a bottom frame 1, a tower frame 4, a winding machine 5 and a power machine 9. The well drilling machine has the characteristics of compact structure, suitability for different stratum conditions, high work efficiency, low engineering cost and good quality of foundation piles. Besides, compared with two hole forming machines respectively in a rotary type and a punching and grabbing type, the well drilling machine still has the advantages of material saving, investment reduction and convenient use and management. The well drilling machine is mainly used for extracting deep groundwater and forming holes on foundation filling piles in construction.

Description

Rotary punching and gripping borer
The invention belongs to well-digging (foundation pile pore-creating) facility.
At present, be used to exploit the facility of deep phreatic water and building lot pore-creating, as CN2072147U light efficient water drilling rig, this is a kind of swinging trepan, mainly is made up of engine, hoist engine, rotary disk, gearbox, hollow stem, drill bit, underframe and pylon; Surplus slag has a strong impact on pile quality at 40 to 50 centimeters at the bottom of engineering construction process mesopore, particularly runs under the sand cobble stratum condition and can't carry out work.The punching and grabbing machine of CN2040137U multiple aperture Impact claw awl head and for example, this is that a kind of dashing grabbed the formula well sinker, mainly unloads device, Impact claw awl head, underframe and pylon by engine, hoist engine, extension and forms; Surplus slag improves pile quality can grab clear opening in the engineering construction process at the bottom of, and, under the sand cobble stratum condition, can carry out work in the same old way.But, bigger and construction costs is high than inefficiency, the energy consumption of light efficient water drilling rig.When engineering construction, just need have water drilling rig and dash and to grab well sinker; Equipment investment is many like this, uses and manage inconvenience.Therefore, still need well-digging (foundation pile pore-creating) facility are changed new creation.
The purpose of this invention is to provide a kind of Different Strata condition exploitation deep phreatic water and high rotary punching and gripping borer of architecture foundation pile pore-creating quality of adapting to.
Realize finishing above-mentioned purpose of the present invention by following design and mode:
This rotary punching and gripping borer, comprise pylon and underframe, the hoist engine of installing on the pylon, engine, gearbox, rotary disk and slush pump, the wire rope of hoist engine involves the hollow stem hung and the revolution auger of drill bit on pylon, it is characterized in that the extension that pylon is provided with replaceable hollow stem, drill bit unloads device and Impact claw awl head.
The present invention turns round trepan and grabs the well sinker integrator with dashing, and compact conformation not only has the Different Strata of adaptation condition, and high efficiency, construction costs is low and pile quality good.And, and with the revolution trepan with dash and to grab two borers of well sinker and compare, economical with materials still there is, reduces production costs, uses and manages all advantage easily.
Accompanying drawing is represented rotary punching and gripping borer concrete structure of the present invention.
Fig. 1 is this rotary punching and gripping borer.
Describe details of the present invention and operating mode in detail below in conjunction with accompanying drawing.
This rotary punching and gripping borer is with the revolution trepan with towards grabbing the synthetic method that well sinker adopts shared pylon 1, underframe 4, hoist engine 5 and engine 9.Unload device 2 at pylon 1 extension of hanging oneself, be equipped with hollow stem 14, drill bit 15 and Impact claw awl head 18.Hoist engine 5 is installed on underframe 4, engine 9(adopts motor), gearbox 11, rotary disk 13 and slush pump 16 form rotary punching and gripping borer.
The operating mode of this rotary punching and gripping borer is as follows:
1, swinging drilling well:
At first actuating motor 9 and start slush pump 16 then closes one-way clutch 10, and the big pinion 12 transmission rotary disks 13 of gearbox 11 make hollow stem 14 and drill bit 15 rotations, promptly begin drilling well.In creeping into, to loosen the wire rope 3 of hoist engine 5 lentamente, hollow stem 14 and drill bit 15 constantly bore down to the stratum, silt that is stirred or the landwaste that is ground are promptly sneaked in the mud, slush pump 16 is with high-pressure slurry, send at the bottom of the hole through high-pressure rubber pipe 17, hollow stem 14, drill bit 15,, take ground out of by the annular gap between hollow stem 14 and hole arm so as to cooling drill bit 15 and with the landwaste that cuts.When top hollow stem 14 falls near rotary disk 13, just connect hollow stem 14 again, continue then to creep into.Like this, go round and begin again, change brill circularly, constantly discharge landwaste, boring is reached till the needed degree of depth.
2, dashing the formula of grabbing digs a well:
Equally, first starter motor 9 can be operated hoist engine 5 and bore, impacts, grabs soil under breaking off relations and promote, link up with and unload the soil well-digging, and concrete operation method is as follows:
Awl down breaks off relations: pull handle 6, make Impact claw awl head 18 slightly rise a little, 7 holdback clutchs 8 of footbrake at once slowly loosen brake 7 then, and Impact claw awl head 18 is descended slowly, and Impact claw awl head 18 can leave hangs three hooks that unload on the device 2.
Impact: during 2 to 3 meters away from shaft bottom of Impact claw awl heads 18, be totally released brake 7, Impact claw awl head 18 freely falling bodies are impacted be.
Grabbing soil promotes: after the impact, pull handle 6, hoist engine 5 is just being changeed at once.Wire rope 3 rises, and at this moment Impact claw awl head 18 just can be finished and grab the soil action, and whole then Impact claw awl head 18 rises.
Hook: Impact claw awl head 18 promotes, and runs into to hang and unloads device 2, when tangling Impact claw awl head 18 automatically, checks brake 7, waits and unloads soil.
Unload soil: after treating that Impact claw awl head 18 tangles, just unearthed dolly is moved to conehead 18 times, loosen brake 7 then, Impact claw awl head 18 relies on the balance weight body gravity to open blade 19, and soil is discharged in the dolly, pushes dolly impacts of can breaking off relations again open, carries out the next one and circulates.So, carry out again and again, can get the well (hole) of desired depth.
In general stratum pore-creating, use the revolution drilling well, high efficiency and construction costs are low.Surplus slag of Ex-all and sand cobble stratum pore-creating at the bottom of the hole of revolution pore-creating are used to dash and are grabbed well-digging, can grab surplus slag at the bottom of the clear opening, improve pile quality.Owing to the revolution drilling well with towards grabbing the shared pylon 1 of well-digging, underframe 4, hoist engine 5 and motor 9.Thereby, economical with materials, reduction equipment cost, and use and convenient management.
