The utility model is characterized in that the screen cleaning mechanism is composed of a combined chain row and a screen cleaning body, the screen cleaning mechanism is installed on the running frame in a vertical state with the railway, the inner side of the running mechanism (the side near the railway) adopts a toothed rail running structure, the outer side adopts a crawler running structure, the digging beam of the digging mechanism is in triangle shape, and a ballast conveying mechanism is arranged between the digging mechanism and the screen cleaning mechanism.

Description

Railway limit quarrel screen scarifier

The utility model relates to the railway limit quarrel screen scarifier that a kind of railroad ballast cleaning equipment particularly relates to cleaning railroad tie head outer side edges quarrel.

Railroad ballast is selected rubble or cobble material usually for use, through using necessary cleaning to protect the railway roadbed quality after a while.Quarrel screen scarifier in the railway limit of use adopts vibrations cleaning technology at present, and it is to deliver to after ballast is dug out in the vibrations cleaning case, leans on the vibrations of cleaning case that dirt is dropped out removing by sieve aperture, is cut only by the backfilling mechanism backfill; In addition, this screen scarifier supports its traveling with two rails.The deficiency of this screen scarifier is: owing to adopt the not only mechanical center of gravity high stability of restriction of vibrations cleaning structure poor, and also therefore width can not can not use on electrified sections by the position of electrification railway contact net column more greatly; In addition, it adopts two rail supported travelings, difficulty when outer rail is equipped with.

The purpose of this utility model is: design that a kind of center of gravity is low, good stability, easy to use, can be by the railway limit quarrel screen scarifier of electrification railway contact net stud.

The purpose of this utility model is achieved in that at the medial extremity of the master and slave moving axis of walking frame (near rail one side) gear is housed, it be located at the interlock mutually of ground rack rails, outboard end is the crawler belt travel structure.Improve in order to lower the center of gravity stability with digging mechanism be contained in walking frame below make it along limit quarrel baseplane work, the dirt excavated quarrel is by sending quarrel mechanism to deliver in the centrifugal cleaning case on the combination chain row, the sieve cleaning mechanism and the railway that are made of parts such as combination chain row and casings are installed on the walking frame in vertical direction, deliver to the dirt quarrel on the combination chain row in the cleaning case because vibrations that combination chain row (vertical railway direction) is produced when rotating and centrifugal action dirt are discharged from combination chain row bottom and sewage draining exit, be cut only in casing baffled stop to drop to carries out backfill on the backfilling mechanism.

Improve stability and dwindled plant width and can be used for electrified section owing to taked above design scheme to reduce the equipment center of gravity, used also more conveniently, reached the purpose of this utility model.

Below in conjunction with drawings and Examples the utility model is further specified:

Fig. 6 is the backfilling mechanism schematic diagram, among the figure: 1 swelling device; 2 driven cylinders; 3 bracing frames; 4 motor; 5 drive sprockets; 6 driven sprockets; 7 drive rolls.

Fig. 7 is the walking frame schematic diagram, among the figure: 6 driving shafts; 7 driven shafts; 1 binding-beam; 9 walking gears; 2 lifters.

In Fig. 1: digging mechanism 1 is installed in below the walking frame, rotate by Motor Drive digger chain and tooth, it digs out and delivers to the entrance of quarrel mechanism 2 with the dirt of sleeper subfacies quarrel, carries out cleaning (digging mechanism with send quarrel mechanism be power with motor on the same stage) in the centrifugal cleaning case owing to send rotation that quarrel mechanism send the quarrel tooth promptly the dirt quarrel to be delivered to.Centrifugal cleaning case and railway are installed on the walking frame in vertical direction, its motor mounting is at the top of casing, driving combination chain row simultaneously by drive sprocket rotation in the feed belt drive case turns round perpendicular to the railway direction, dirt is discharged from the sewage draining exit of combination chain row bottom and casing end plate respectively under vibrations and action of centrifugal force, and clean quarrel is dropped on by stopping of casing Internal baffle on the conveyer belt of backfilling mechanism 4 carries out backfill.More than each mechanism moving by the running mechanism holder, the power of traveling is motor, drive traveling by traveling reduction box 5, medial extremity (near the rail end) at driving shaft 6, driven shaft 7 is equipped with walking gear 8, gear 8 and the rack rails 16 interlock travelings that are laid on the sleeper head, outboard end at driving shaft 6, driven shaft 7 adopts the crawler type travel structure, and is very convenient when this travel structure uses.

In Fig. 2 and Fig. 3: digging beam is triangular in shape, and along limit quarrel baseplane work (anterior angle has downward-sloping slightly), the triangle digging beam not only can increase its intensity can also prevent that machinery from swashing.On digger chain 6, three tooth 7 in upper, middle and lower are installed every 100 millimeters, because the driving of drive sprocket 2 and the control of driven sprocket 4, excavate thereby make digger chain 6 drive tooth 7 along the outer rim revolution of digging beam 5.Excavation depth is 240～350 millimeters.

In Fig. 4: send quarrel mechanism that dirt quarrel is sent into excessive mechanism before the sieve cleaning mechanism, be provided with and send quarrel mechanism can reduce the height of sieve cleaning mechanism, thereby the center of gravity that has reduced complete machine is improved stability.Thereby the rotation of Motor Drive turning cylinder 3 drives rolling disc 4 and send quarrel tooth 2 that the dirt quarrel is delivered on the cleaning chain row of sieve cleaning mechanism.On the periphery of rolling disc 4, be equipped with 4 groups and send the quarrel tooth.

Fig. 5 is a centrifugal screen scarifier vertical section constructional drawing, sieve cleaning mechanism adopts centrifugal cleaning technology, do sieve nest with combination chain row 3, remove by clean-up scraper 7 back down by the dirt sieve that combination chain row's rotation (vertical railway direction) is less with some, and another partly dirt since combination chain row when rotating action of centrifugal force thrown under the curb from the sewage draining exit 9 on the end plate, clean quarrel is because the effect of casing 5 top flap 4 falls it, drop on the backfilling mechanism (belt conveyor), be backfilling into quarrel position, limit by backfilling mechanism.Backfilling mechanism is installed in the cleaning case from the rectangular opening 10 on the box side relative with sending the quarrel mouth.Lifter 11 also is housed in order to adjust height on the side plate that rectangular opening 10 is arranged.Combination chain row 3 is driven by drive sprocket 1, by driven sprocket 6 controls, also has tensioner sprocket wheel 2 and eccentric wheel 8 control cleaning chain rows' rotation in addition.

Fig. 6 is the backfilling mechanism schematic diagram, and backfilling mechanism is actually a belt conveyor, and it extend into the clean quarrel that will fall in the cleaning casing thereon and is transported to limit quarrel position and carries out backfill.

Fig. 7 is the walking frame schematic diagram, and walking frame is mainly by driving shaft 6, driven shaft 7, binding-beam 1 is formed, at driving shaft 6, an end of driven shaft 7 has walking gear 9 respectively to be provided with lifter 2 at the corner location of walking frame, and it cooperates the height of adjusting associated mechanisms with corresponding position.

The utility model: owing to be to work along the railway, the narrower and basis of the scope of operation Machine is comparatively heavy, therefore, has taked piecemeal to be assemblied to form when implementing the utility model Measure namely is divided into this machine: walking frame, and traveling reduction box and motor, crawler attachment, Digging mechanism, cleaning and send the quarrel mechanism, several parts such as backfilling mechanism and distribution box are delivered to It is comparatively convenient that use is assembled at the scene.
