Abstract
Disclosed is a trolley stabilizer equipped with a trolley system sealing device, which comprises a stabilizer main body(1) and a plurality of trolleys(5)installed on the stabilizer main body(1). Hydraulic oil cavities(21) are axially installed on all the trolley shafts(2); screwed plugs(6) are installed on the mouths of the hydraulic oil cavities at the end parts of the trolley shafts(2); pistons(7) are arranged in the hydraulic oil cavities(21); oil guide holes(22) are arranged between the hydraulic oil cavities(21) and the outer walls of the trolley shafts(2); and annular hydraulic sealing oil grooves(51) are arranged on the inner walls at the middle parts of the trolleys(5). The trolley system of the trolley stabilizer is provided with a set of hydraulic sealing device which can have the function of preventing the drilling mud from entering the spaces between the trolleys and the trolley shafts and causing rust and abrasion, thus effectively protecting the trolley system. By making use of the hydraulic balancing function of the hydraulic sealing device, the trolley stabilizer effectively improves the working performance of the whole machine and at the same time provides lubrication to the trolley system, and the service life and the durability of the trolley stabilizer can be improved by 15-20%.
Description
Technical field
The utility model relates to petroleum machinery, particularly a kind of roller stabilizer.
Background technology
The roller system of existing roller stabilizer is to be made of roller, roller mount, roller shaft and bolt etc., it in the course of the work drilling mud be easy to enter in the annular gap between roller and the roller shaft, produce the application life of corrosion and wearing and tearing, reduction roller stabilizer, the in use also as easy as rolling off a log eccentric wear phenomenon that produces on roller shaft causes the roller shaft premature failure.
The utility model content
Technical problem to be solved in the utility model is at the above-mentioned shortcoming of existing roller stabilizer, and a kind of roller stabilizer that has the roller system sealing device is provided.
Technical solution of the present utility model is: it comprise the stabilizer body and by roller shaft, go up axle bed and following axle bed and be installed in several rollers on the stabilizer body, be axially arranged with an end opening on each roller shaft and be positioned at the hydraulic fluid chamber at roller shaft middle part in an end, the other end of roller shaft, on the hydraulic oil accent of roller shaft end plug is installed, be provided with piston in the hydraulic fluid chamber, radially be provided with oil guiding hole between the outer wall at hydraulic fluid chamber and roller shaft middle part, the inwall at roller middle part is provided with the annular hydraulic packing oil groove that is connected with the oil guiding hole of roller shaft.
Technique effect of the present utility model is: it is provided with a cover hydraulic seal device at roller system; can play and prevent that drilling mud from entering the effect that produces corrosion and wearing and tearing between roller and the roller shaft; thereby protect roller system effectively; utilize its hydro-cushion function; improved the service behaviour of complete machine effectively; the pair roller system provides lubricated simultaneously, can make the application life of roller stabilizer and durability improve 15%～20%.
