A kind of engineering geological investigation hand drill rig
Technical field
The present invention relates to a kind of rig, particularly a kind of engineering geological investigation hand drill rig.
Background technology
In recent years, along with the fast development of mountain area engineering construction (as mountainous area highway), prospecting task also increases gradually.Usually, the solution that intermountain depression, simple stratum are commonly used has following three kinds:
(1) adopt common XY-100 type rig to drill.Common XY-100 type rig is made up of head, diesel engine, base, elevator, boring tower, drilling rod, core barrel, sleeve pipe, water pump, water pumper etc., and plant equipment is heavy, and the whole series weigh 1 ~ 2 ton, is not easy to carrying, wastes time and energy.
(2) conventional simple and easy exploring equipment is Luoyang Spade, and Luoyang Spade forms by shoveling head, weight linear meter and extension bar.In use, hitting ground by manually being stabbed vertically downward by Luoyang Spade, utilizing shovel head the soil zone of underground can be gone out, according to the character of structure, color, density and the various inclusion analysis shallow underground soil layer that band is unearthed.Although equipment is light, simple to operate, but to adopt be manually power, creeps into slowly, tunnelling footage is less, and run into the phenomenon that underground water can be difficult to fetch earth when tunneling in cohesive soil, in addition, if run into loose layer of sand, also cannot be taken to ground.
(3) adopt Backpack type rig to carry out the prospecting of mountain area intermountain depression, a whole set of rig and related accessory are loaded knapsack, and simply assemble during use, equipment is made up of put-put, drilling rod, core barrel and a set of water system.Drive drilling rod and core barrel to rotate by put-put during use, in hole, carry out water filling by water system.Although Backpack type rig is light, simple to operate, but adopt miniature gasoline engine, driving power is less, rate of penetration is slow, equipment price is expensive.
Summary of the invention
The object of the present invention is to provide that a kind of structure is simple, light, easy to operate, tunnelling footage is large, price is low, be conducive to the engineering geological investigation hand drill rig that engineering geological investigation carries out smoothly.
Object of the present invention is realized by following technical measures: a kind of engineering geological investigation hand drill rig, it is characterized in that: it is the small generator composition of more than 3KW primarily of head, drilling rod, core barrel and power, the clutch end of described head is connected with the upper end of drilling rod, the upper end of described core barrel is connected with the lower end of drilling rod, described small generator and head, for being electrically connected, described head are detachably provided with the hand handle that can hold for 2 ~ 3 people.
Head of the present invention is provided with hand handle, and can facilitate 2 ~ 3 people's operations, and adopt the small generator that power is more than 3KW to provide power, generator is small, power is sufficient, improves driving speed and the degree of depth.In addition, structure of the present invention is simple, light, easy to operate.
As one embodiment of the present invention, described small generator employing output voltage is 220V, power is the gasoline engine generator of 3KW.
As a modification of the present invention, described small generator is provided with the safety switch for automatically closing starting switch during abnormal electrical power supply, when starting working, open starting switch, make engine fire, and open safety switch, when quitting work, closed safe switch, and close starting switch, generator is stopped working.Safety switch adds the security of onsite application rig.
As a further improvement on the present invention, the bottom of described core barrel has the port fetched earth.Creep into after terminating to take out core barrel, the soil body is slowly disclosed from passage port by the reinforcing rod that usable diameter is less.Avoid the Luoyang Spade shovel large chance water of head opening or meet layer of sand and be difficult to get the situation of soil, turn avoid the situation that the soil body in Backpack type rig core barrel is difficult to take out.
The present invention can also do following improvement, described engineering geological investigation hand drill rig also comprises bearing, described bearing comprise base, pillar, for clamping holder and the elevating bracket of head, described base is made up of to make drilling rod stretch to ground between two base plates the base plate of pair of parellel, described pillar is vertically fixed on the rear end of base plate, described holder is located on elevating bracket, and described elevating bracket is sleeved on pillar and also can moves up and down along pillar and locate.When the present invention creeps in rock, can be erected on bearing, control drilling rod lifting by bearing, thus realize steadily creeping in rock.
As one embodiment of the present invention, described elevating bracket is primarily of pedestal, handle, rotating shaft and tooth card composition, described pedestal is placed on pillar, described holder is positioned on pedestal, described tooth card is the strip blocks that front has tooth, described tooth card is vertically fixed on pillar, one end of described rotating shaft is fixed on handle, the other end inserts into the inner through pedestal, the through hole passed for rotating shaft at described pedestal is provided with the bearing be placed in rotating shaft, the end that rotating shaft is stretched in pedestal is provided with gear, described gear is meshed with the tooth on tooth card, rotated by turning handle driven gear, gear and tooth card coordinate and pedestal are moved on pillar, and then drive holder lifting, be provided with set screw at the back side of described pedestal, described set screw is screwed into pedestal and is pushed against positioning seat body on pillar.
Engineering geological investigation hand drill rig of the present invention also comprises the drill bit of short cylinder shaped, to change dissimilar drill bit on the lower end that described drill bit is detachably arranged on core barrel.Different Strata is suitable for the drill bit of employing unlike material to be drilled, and soil layer can adopt alloy bit, and lithostratigraphy then adopts diamond bit.
Compared with prior art, the present invention has following significant effect:
(1) head of the present invention is provided with handle, and can facilitate 2 ~ 3 people's operations, and adopt the small generator that power is more than 3KW to provide power, generator is small, power is sufficient, improves driving speed and the degree of depth; In addition, structure of the present invention is simple, light, easy to operate, and price is low, is conducive to engineering geological investigation and carries out smoothly.
(2) on generator, install safety switch additional, ensure that the Electrical Safety in drilling process.
(3), after creeping into end taking-up core barrel, the soil body is slowly disclosed from passage port by the reinforcing rod that usable diameter is less.Avoid the Luoyang Spade shovel large chance water of head opening or meet layer of sand and be difficult to get the situation of soil, turn avoid the situation that the soil body in Backpack type rig core barrel is difficult to take out.
(4) when the present invention creeps in rock, head can be erected on bearing, controls drilling rod lifting, thus realize steadily creeping in rock by bearing.
