Description
Technical field
The present invention relates to piling machinery technical fields, particularly, are related to a kind of rotary drilling rig and construction method.
Background technique
Rotary drilling rig is a kind of Hydraulically Operated Equipment, is to drive drilling rod by controlling to the rotation of power head and pressurization
And the rotation and pressurization of drilling bucket are cut in soil to drilling bucket, and then drilling bucket band portals by the promotion of master winch steel wire rope
Outside, the position for drilling bucket being taken to offset bore then is acted by the revolution of rotary drilling rig, and native disk opening drilling bucket is got rid of by power head
The periodic job equipment that goalkeeper's soil is easily discharged out of the hole.
At present in industry there are mainly two types of the modes of rotary drilling rig drilling bucket casting, one is commonly a cubic metre of earth formula is got rid of, that is, start
It is braked suddenly after power head rotation, then rotary power head is braked suddenly again, takes this " move-stop-moving-stop-" again and again
Mode of operation, the soil inside drilling bucket shaken loose with the physical phenomenon of inertia throw away come;Another is increased at power head
Add a kind of high speed to get rid of native device, i.e. speed reducer reduction ratio gear is changeable, it is kept off when operation drilling using large torque low speed,
It is kept off when mentioning brill and getting rid of soil using small torque high speed, the reduction ratio for controlling speed reducer in this way realizes the height of power head
Speed gets rid of soil, and power head revolving speed can reach 100r/min or more when top gear, is thrown the soil of drilling bucket with the effect of centrifugal force
It throws away and, reach casting purpose.
Wherein, the first casting mode is commonly got rid of clay model formula and is mainly had the disadvantage that: although 1), using " move-stop-move-
Stop-" mode of operation, but clay still can't get out from drilling bucket, and sometimes up to a hundred recycle these clays back and forth and also can't get out,
Time-consuming makes drilling bucket casting working efficiency very low long very much;2), the circulation of " move-stop-moving-stop-" in this way, centre is not any
It buffers with damping and protects structural member, all contact surfaces are all the collision of steel to steel, grievous injury drilling rod and power
First-class structural member leads to the cracking of mast guide rail, drill rod body and spline weld seam;3), in this way " move-stop-move-stop-" circulation,
The people other than 1km can be allowed to hear, especially give the noise pollution of neighbouring bringing on a disaster property of resident;(4), special to aperture drilling bucket
It is not for the drilling bucket within diameter 800mm, clay is not arranged not come out completely.Second of casting mode mainly has the disadvantage that:
(1), it when rotary drilling rig bore operation, if encountering argillic horizon aperture stake of the drilling bucket diameter within 800mm, gets rid of soil and is not unearthed;
(2), in the case where getting rid of soil at a high speed, the output speed of motor is usually more than 4000r/min, the operating of such high speed, it is easy to burn
Bad motor;Meanwhile 5 times or more when reaching work of the output speed of speed reducer, the operating of such high speed easilys lead to subtract
Fast machine gear oil is insufficient to the lubrication of gear, leads to speed reducer internal temperature superelevation, for a long time so that by Overheating Treatment
Reducer gear softening, intensity are had a greatly reduced quality, and speed reducer is caused the failures such as broken teeth occur.
For the problems of the mode of above two rotary drilling rig drilling bucket casting, has in this field and arranged for drilling bucket
The research of earthwork formula, such as the patent of invention of Patent No. 201110103357.9 disclose the coherent opening sluice gate of one kind and force
