Abstract
The utility model provides an anti-explosion electro-hydraulic rotating joint for mining, and aims to solve the problems that when the same rotating mechanism requires electro-hydraulic control at the same time, a rotating joint or an electric conduction slip ring is used independently, and the connection requirement cannot be met; and equipment used in a coal mine has certain anti-explosion requirements for applied parts. The technical scheme of the anti-explosion electro-hydraulic rotating joint for mining is as follows: a rotating shaft penetrates through the anti-explosion electric conduction slip ring and the hydraulic rotating joint sequentially and is inserted into a stator at the end part of the hydraulic rotating joint; and the hydraulic rotating joint comprises a fixed end and a rotating end, and the rotating end is inserted into the fixed end, so that a sleeve is formed. The anti-explosion electro-hydraulic rotating joint for mining has the advantages as follows: function integration can be realized; for electro-hydraulic simultaneous control equipment of a swing mechanism, and arrangement of pipelines of the swing mechanism can be greatly simplified; and the anti-explosion electro-hydraulic rotating joint can also meet the I-type anti-explosion requirement and can be directly applied to coal mine products and equipment.
Description
Technical field
The utility model relates to a kind of swivel joint, particularly a kind of mine anti-explosion electricity liquid swivel joint.
Background technique
At present, for hydraulic system or electric system, swivel joint or conducting slip ring are used in connection from the fixed mechanism system to the rotating machinery system usually, but when same rotating machinery needs electrichydraulic control simultaneously, use separately swivel joint or conducting slip ring and all can't reach connection request, and the equipment that uses in the colliery also will have certain requirement of explosion proof to applied parts.
Summary of the invention
For addressing the above problem, the utility model provides a kind of mine anti-explosion electricity liquid swivel joint.
The technical solution of the utility model is: it comprises swivel joint and conducting slip ring, it is characterized in that: said conducting slip ring is explosion-proof conductive slip ring, said swivel joint is hydraulic rotary joint, and hydraulic rotary joint comprises fixed end and round end, and fixed end is with stator; Round end inserts fixed end, forms sleeve; At the uniform in the shape of a spiral some filler openings in the tubular side of fixed end, each filler opening is communicated with the annular oil groove of fixed end inwall; The oil outlet of round end is on sleeve outer wall, and oil outlet is corresponding one by one with filler opening, and each oil outlet is communicated with the oil duct of round end outer wall;
Running shaft passes explosion-proof conductive slip ring and hydraulic rotary joint successively, and inserts in the stator of hydraulic rotary joint end; Cover has some electrical interface slip rings, electrical interface slip ring to be fixed on running shaft near a side of stator on running shaft, and each electrical interface slip ring contacts with a carbon brush on carbon brush holder, and carbon brush holder is fixed on stator.
Swivel joint is connected by fastening piece with the shell flange of explosion-proof conductive slip ring, and the round end of swivel joint is connected with rotor by fastening piece, and running shaft inserts stator, realizes synchronous rotary.
Threading hole is arranged in the middle of swivel joint, the hydraulic fluid port of hydraulic pipe line input end is on the tubular fixed end surface that the helical curve wire is distributed on swivel joint, each hydraulic fluid port is connected with the oil duct of round end by the annular oil groove in cylindrical wall, the hydraulic fluid port ring-type of round end is distributed on periphery, the round end hydraulic fluid port is corresponding one by one with the fixed end hydraulic fluid port, realizes that the correspondence of oil circuit connects.The round end of described swivel joint inserts fixed end formation sleeve and makes and is screwed.
Stator case connects as one by bolt and fixed end explosion-proof casing, and its surface of contact meets the coal mine explosion-proof standard.Bearing is built in stator case, and it is spacing fixing by the fixed end explosion-proof casing that running shaft inserts bearing, and carbon brush is fixed on the carbon brush holder of enclosure interior, and carbon brush holder and stator case are integrated, and the electrical interface slip ring is fixed on running shaft, contacts with carbon brush.Wire terminals is drawn by rotary barrel inside.
Compared with prior art, the beneficial effects of the utility model are: can practical function integrated, and to the electric liquid of swirl gear control apparatus simultaneously, can greatly simplify the installation of the pipeline pipeline of swirl gear and arrange.This use is novel also has the I of satisfying class requirement of explosion proof, can directly be applied in the product facility of colliery.
