Description
The ballast aggregate screen scarifier is a kind of dirty slag of railway roadbed that digs out below track, sends into the sieve cleaning mechanism of ballast aggregate, then the ballast aggregate behind the cleaning is backfilling into a kind of ballast aggregate cleaning combined mechanical on the railway roadbed by backfilling mechanism again.
Existing ballast aggregate screen scarifier divides two big classes at present, and a class is cleaning mechine operation in orbit.Power is bigger, and efficient is higher.But must block circuit.For example U.S.'s patent 4083775 in 1978 and patent 4203493 in 1980; Japan clear 56-30402 of patent in 1981, clear 56-31401.Another kind of is cleaning mechine operation on track both sides and curb.For example day bear formula screen scarifier of Japan and order are deceived the formula screen scarifier.This class screen scarifier does not influence the normal operation of train.But this class screen scarifier all is monolateral screen scarifier.Because the structure of railway roadbed is different with the resistance that excavates the circuit cross section, and the digging mechanism of screen scarifier is increased the weight of, and perhaps takes other ancillary method at the another side of screen scarifier, causes screen scarifier efficient low, uses inconvenience etc.
The purpose of this utility model is exactly that the ballast aggregate screen scarifier is upper track not on busy rail track, does not cut off traffic, as long as train goes slowly, just can carry out sorting operation and ballast aggregate screen scarifier at the bottom of a kind of small-sized bilateral pillow that designs.
This ballast aggregate screen scarifier is installed for the axis bilateral symmetry with the wire center, and every side is formed by excavation, cleaning, backfill, traveling and elevating mechanism five parts, each one-tenth system.The both sides girder is linked to be an integral body by the girder yoke plate by bolt.Console is installed in the right side of direction of advance, and each part device is carried out unified distribution.
Digging mechanism is in the sleeper bottom, is made up of 76 or 68 chain links and excavates the moulding chain, around two axis of rotation runnings, drives dirty ballast aggregate and enters the screen box of sieve cleaning mechanism from the screen box inlet by being welded on take off plate and the grilled teeth that excavate on the moulding chain.Because the rotation of sieve cleaning mechanism, the dirty slag that enters screen box is rolled in screen box and reach the other end, dirty soil passes sieve crack with holes and drops on the curb, the rock ballast of cleaning is by the effect of sieve band rotary centrifugal force, by being left on the conveyer belt of backfilling mechanism, the rock ballast of backfill conveyer belt after with cleaning is backfilling on the circuit railway roadbed equably through even slag mechanism.
In the running mechanism, on the traveling axle that reduction box stretches out, a traveling driving gear is installed, parallel with each passive travelling wheel of front and back, they are bearing the total weight in the work of ballast aggregate screen scarifier, on the sleeper two ends and be parallel to rolling-operation on the rail of circuit.The rail use of can substituting at any time.Elevating mechanism drops on the rail when making the work of ballast aggregate screen scarifier by bolt and nut fully, and this machine is dropped on the ground.
