Abstract
A double-cylinder, double-spring and double-slip hydraulic chuck comprises an upper hydraulic slip group and a lower hydraulic slip group. The hydraulic slip groups are arranged on a spindle, each hydraulic slip group includes a disc spring, a hydraulic cylinder, a supporting sleeve, a retainer ring and a slip, a bearing is arranged between each hydraulic cylinder and the corresponding retainer ring, the bearings are aligning thrust roller bearings, oil storage sealing sleeves are arranged on the outer portions of the bearings, the lower ends of the oil storage sealing sleeves are connected with the supporting sleeves, left-handed spiral grooves are disposed on the inner walls, which are opposite to outer rings of the bearings, of the upper portions of the oil storage sealing sleeves, and oil storage cavities are disposed among the lower portions of the oil storage sealing sleeves and inner rings of the bearings. Original enchantment force is doubled in a net increase manner, and lifting capacity of a drilling machine is greatly improved. The oil storage sealing sleeves rotate at high speed, lubricating grease is thrown out upwardly along the inner walls of the sealing sleeves by the aid of centrifugal force, at the moment the lubricating grease is downwardly propelled to enter bearing tracks by the aid of the left-handed spiral grooves due to downward component force, and the needed lubricating effect is realized. The double-cylinder, double-spring and double-slip hydraulic chuck realizes the effects of sealing and oil storage by the aid of lubricating media.
Description
Technical field
The utility model relates generally to industries such as geology, metallurgy, coal, the hydrology, foundation pile engineering, based on vertical shaft type drilling technique equipment and the all-hydraulic core drilling technical equipment that diamond and carbide alloy creep into, particularly a kind of twin-tub two-man act dual-grip oild chuck.
Background technology
Since 2006, since State Council's promulgation " about strengthening the decision of geological work ".China's mining industry is recovered rapidly, and geological core drilling increases fast, mineral exploration input, corresponding continuing to increase.Geologic prospect equipment, spindle-type core drill still are the army of absolutely main force of exploration market.Deep prospecting, look for the miner to enter Rapid development stage, geological and mineral preliminry basic research that we can say China's new round mainly with attack look for deeply blind, visit the limit and know the real situation and attach most importance to.Geological prospecting from the past superficial part, the deep turn to deep prospecting, " second looks for the space, ore deposit " of seeking buried ore and ore deposit, deep is main target.Just at present, the deep hole of the whole nation more than 2000 meters spread all over a plurality of provinces, as: provinces such as Hebei, Shandong, Anhui, Liaoning, Sichuan.But the small-bore larger caliber of getting the core hole and surpassing 2000 meters that surpasses 3000 meters is got the core hole.The existing rock-core borer power deficiency of having showed off one's talent or competence.Especially, the Wenchuan earthquake Science Drilling WFSD-2 hole of Hot work in progress at present, 150 millimeters of whole bore dias, 2000 meters of hole depths, core is got in full hole.The WFSD-4 hole, 150 millimeters of whole bore dias, 3000 meters of hole depths, hole depth and aperture are big, because the ability of existing domestic market rock-core borer is not enough.They adopt rock-core borer and oil-well rig associating section construction to finish.Consider that from the angle of engineering cost and efficient it is low to hank, efficient is high relatively, scarce capacity, and in the early stage of finishing engineering, it is intact that the later stage engineering adds the oil-well rig that drives on the top by rotating disk.
Domestic, external diamond wire line coring, deep drilling surpasses 3000 meters records, all is to adopt the oil rotating disk to add the rig that the top drive system creeps into to finish.
Greater than 3000 meters superdeep holes exploration, if, adopt the spindle-type core drill exploration to make comparisons with adopting the oil-well rig exploration, obviously can there be following problem:
1. the supporting cost height of oil-well rig.The oil rotating disk adds the associated part of top drive system rig and supporting oil rig, slush pump etc., almost be the supporting boring tower of vertical shaft rock-core borer, slush pump etc. associated part 2-5 doubly.
2. oil-well rig equipment is huge, and the resettlement difficulty cycle is long.
3. oil-well rig is huge, and floor space is big, the smooth well site and the cost height of repairing the roads.
4. oil-well rig is when using rotating disk to drive, and no oil cylinder pressurizes, decompression, and drilling efficiency is low, the construction cost height.
Existing deep hole geology rock-core borer can not satisfy its probing demand.Can satisfy the deep drilling requirement with oil-well rig, but cost is too high, very expensive.In addition, the oild chuck self-enrichment is poor, when the support set that is used for oil storage rotates, and the lubricating grease in the support set, because centrifugal force, lubricating grease will throw away along the support set inwall, especially during high speed operation, needs frequently to refuel.Market is to satisfying deep hole rock core exploration requirement, and performance is good, and the rig demand that drilling ability is stronger is more urgent.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, has proposed a kind of high lubricating effect, satisfies the twin-tub two-man act dual-grip oild chuck that deep drilling requirement, clamping ability have improved the hoisting power of rig by force, greatly.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of twin-tub two-man act dual-grip oild chuck, comprise the hydraulic pressure pipe slips group that is located on the main shaft, described hydraulic pressure pipe slips group comprises the dish spring, hydraulic cylinder, support set, collar and slips, be provided with bearing between hydraulic cylinder and the collar, be characterized in: on main shaft, be provided with two groups of hydraulic pressure pipe slips groups up and down, described bearing is the aligning thrust roller bearing, the outside of bearing is provided with an oil storage sealing shroud, the lower end and the support set of oil storage sealing shroud join, the top of the oil storage sealing shroud inwall relative with bearing outer ring is provided with left-handed helicla flute, is provided with the oil storage cavity between the bottom of oil storage sealing shroud and the bearing inner race.
The technical problems to be solved in the utility model can also come to realize that further left-handed helicla flute is a rectangular channel by the following technical programs.
The utility model compared with prior art is provided with up and down two groups of hydraulic pressure pipe slips groups, twin-tub two-man act dual-grip, add the power of holding on original basis net increase one times, improved the hoisting power of rig greatly.Adopt the aligning thrust roller bearing, the outside of bearing is provided with the oil storage sealing shroud, the left-handed helicla flute that the oil storage sealing shroud is provided with, bearing outer ring is a smooth surface, and sealing shroud is in rotation at a high speed, and lubricating grease upwards throws away along the sealing shroud inwall by centrifugal force, this moment, left-handed helicla flute was because downward component, lubricating grease is advanced downwards, enter bearing track, to reach required lubricant effect.Utilize lubricant medium, reach the effect of sealing, oil storage.
