Abstract
The utility model belongs to a kind of vibration damping equipment in the rotary drill swirl gear.
In this installed, main elastic element selected for use rigidity big, and the buffering vibration absorption ability is strong, endurance, and corrosion resistant belleville spring reduces and absorbs the vibration that vertically produces when rig is worked, the horizontal vibration that produces when using the minimizing of buffering blob of viscose and absorbing rig work.This device solves big, the problem such as equipment failure rate is high, bit wear is fast and the vibration damper life-span is low of the vibration that produces of rotary drill when work.
Description
The utility model belongs to a kind of vibration damping equipment in the rotary drill swirl gear.
Vibration damper has become requisite vibration damping equipment in the rotary drill swirl gear, and this device performance how, directly affects the working life of drill bit, the technology status and the perforation cost of rig.In recent years, successively develop the rubber spring vibration damper both at home and abroad.For example, in April, 1980, the assorted Chi of " mining engineering " (MINING ENGINEERING) of the U.S. was entitled as the vibration damper of introducing in " vibration damper is how to reduce the boring cost ", and the vibration damper of China Anshan iron and steel plant mine research institute, Northeast Polytechnic College development, their structure and characteristics are basic identical, the elastic element that is vibration damper all adopts rubber spring, the vibration damper of this kind form, certain damping effect has been played in the vibration that produces when rotary drill is worked.But, because rubber environment sensitive to external world is easy to fatigue, aging, axial compression height when particularly rig is worked, rubber spring vibration damper more expose the weakness of material itself under the condition of high frequency, big amplitude vibration, caused the vibration damper effectiveness in vibration suppression to descend, reduce working life.The working life of external rubber spring vibration damper is (rig perforation rice number) about 6000 meters, and the working life of domestic rubber spring vibration damper is slightly high, also only is about ten thousand metres.
The present invention is a kind of improvement invention, and its main points are to provide a kind of comparatively desirable elastic element, and promptly belleville spring is as the elastic element in the vibration damper, and belleville spring vibration damper of the present invention mainly comprises the vibration damper upper body.Vibration damper lower body, belleville spring, buffering blob of viscose and overcoat.On the vibration damper; lower body connects with the quill shaft and the drilling rod of rig swirl gear respectively; the belleville spring seat is placed on the vibration damper lower body; setting type has superimposed; three kinds of involutory and combined types; the physical dimension of belleville spring and quantity; will be according to the physical property of the axial compression of rig and drilled mineral and decide; its purposes is minimizing and absorbs the vibration that vertically produces when rig is worked; the laterally vibration of generation when cushioning blob of viscose as minimizing and the work of absorption rig; its position is at vibration damper lower body and overcoat touching position; overcoat removes for connecting on the vibration damper; external down, can also play the seal protection effect.
Be one embodiment of the present of invention below, description and accompanying drawing by to embodiment have provided details of the present invention.
Accompanying drawing is the example structure schematic diagram, vibration damper upper body ［ 1 ］, overcoat ［ 2 ］, vibration damper lower body ［ 3 ］, buffering blob of viscose ［ 4 ］, spring ［ 5 ］.
According to said structure, Anshan Iron and Steel Company's Qidashan iron ore has been made the belleville spring vibration damper, and on the 45-R rotary drill, use, received comparatively desirable effect, on this vibration damper, lower body ［ 1 ］ ［ 3 ］, connect with the quill shaft and the drilling rod of rig swirl gear respectively, the spring ［ 5 ］ that seat is placed on the vibration damper lower body ［ 3 ］ is selected one group of 8 belleville spring for use, be the combined type combination, the vibration that is used for reducing and vertically produces when absorbing rig work, 6 block buffering blob of viscoses ［ 4 ］ have evenly been arranged in vibration damper lower body ［ 3 ］ and overcoat ［ 2 ］ contacting point, material is oil resistant rubber mixes compacting with nylon a composite material, in the vibration that laterally produces, overcoat ［ 2 ］ was except that supplying to connect on the vibration damper when its effect was minimizing and the work of absorption rig, external down, can also play the effect of sealing to vibration damper inside.
Shock absorber of the present invention, owing to select disk spring as flexible member, have that rigidity is big, the buffering vibration absorption ability is strong, endurance, the characteristics such as corrosion-resistant, overcome some shortcoming that rubber elastic shock absorber exists, compare with rubber elastic shock absorber of the same type, be 2 times of rubber elastic shock absorber service life, because vibration damping is obvious, dish-shaped spring shock damper is compared with rubber elastic shock absorber, and improved 5%～10% the service life of rock bit.
