Abstract
A digging chain of a cleaning-sieving machine is used on the cleaning-sieving machine for maintaining railway routes and formed by a rake palm (1), a middle body (2), long prongs (3), short prongs (4), hexagonal sunk screws (5), locking nuts (6), a spring gasket (7), a T-shaped bolt (8) and a chain pin (9). The digging chain of the cleaning-sieving machine is characterized in that a 15-degree-angle is formed by an installing face formed by a prong installing hole center on the rake palm (1) and a rake palm board face, thereby being big in digging area; three reinforcing ribs are cast on the back of a rake board, thereby improving strength of the rake palm (1); the long prongs (3) and the short prongs (4) are installed into the prong installing hole of the rake palm (1) and are locked through the hexagonal sunk screws (5) and the locking nuts (6), thereby being convenient to assemble and disassemble; and three installing grooves are arranged on the uppermost long rake prongs (3) arranged on the rake palm (1), therefore the effective working length of the long prongs (3) can be adjusted by selecting different installing grooves according to abrasion conditions of long prong heads.
Description
Technical field
The utility model relates to a kind of railway track maintenance plant equipment---cleaning car, specifically, relates to a kind of digger chain of cleaning car excavating gear.
Background technology
The cleaning car is to be used for the big machinery apparatus for work of ballast cleaning ballast aggregate on the railway, and the main cleaning vehicle that China uses now has RM80 type, QQS500 type, QS650 type etc.The effect of cleaning car is: ballast aggregate dirty, that harden is dug out under sleeper, after sieving, standard compliant cleaning ballast aggregate is backfilled to railway roadbed, the dirty soil that sieves out, broken quarrel etc. are scavenged into outside the circuit.Excavating gear is one of apparatus for work on the cleaning car.
Digger chain is the critical piece of cleaning car excavating gear, and it mainly is made up of the rake palm, rake teeth, gear ring, straight pin.Rely on sprocket wheel, be bearing in the turning roller that excavates on the guide groove, digger chain constitutes the circulating system of a sealing, is the pentagon shape, leads by promoting guide groove, horizontal guide groove and decline guide groove.Sprocket wheel with drive unit output is meshed digger chain on vehicle frame top, is turned round by chain wheel drive.
During operation, digger chain rotates counterclockwise, and through horizontal guide groove guiding, under rail, excavates and carry ballast aggregate.Rising guide groove digger chain is used to promote ballast aggregate to reciprocating sieve, and roller turns back on the railway roadbed decline guide groove digger chain through the turning.
The rake teeth of digger chain is contained in the installing hole of the rake palm, can freely rotate, and is fastening with gear ring and straight pin, sees Fig. 1 and Fig. 2.Directly contact with ballast during digger chain work, receive intense impact and friction, the fracture easily of the rake palm, rake teeth drops easily, has to often change.When changing rake teeth, need straight pin to be pounded out, squeeze into new straight pin again with special punch.And the straight pin head can produce distortion through beaing, and causes the dismounting difficulty, has to sometimes with gas cutting rake teeth sliced off, and it is time-consuming to require great effort very much when therefore changing rake teeth, especially at the scene.
Summary of the invention
The utility model technical problem to be solved is: a kind of new digger chain is provided, rake palm intensity structurally is improved, make the rake teeth mounting or dismounting convenient.
The utility model solves the technical scheme that its technical problem adopted: digger chain is made up of several identical in structure rake palms, intermediate, long rake teeth, short rake teeth, hexagon socket countersunk flat cap head screw, locking nut, tommyhead bolt, spring washer, chain pin.Adjacent two rakes are slapped and are connected through intermediate, interspersed chain pin in the connecting hole of the rake palm and intermediate, and chain pin is fastening by tommyhead bolt and locking nut; Rake teeth is packed into and harrowed in the installing hole of the palm, and is by hexagon socket countersunk flat cap head screw and locking nut that it is fastening; The installed surface that the rake teeth installing hole center of rake palm constitutes is 15 ° with rake palm plate face angle, and rake backboard face is cast three road reinforcing ribs; On the long rake teeth by three mounting grooves; Long rake teeth is installed in the uppermost installing hole of the rake palm; Hexagon socket countersunk flat cap head screw penetrates long rake teeth mounting groove foremost, after the long rake teeth front end wearing and tearing, can adjust effective active length of long rake teeth through selecting latter two mounting groove.
The beneficial effect of the utility model is that the rake teeth installed surface of rake palm is 15 ° with rake palm plate face angle, has increased excavated area, has improved digging efficiency; Rake backboard face is cast three road reinforcing ribs, has improved the working strength of the rake palm, and it is not interrupted by shock loading easily; Adopt hexagonal sunk screw and the fastening rake teeth of locking nut, tightness is good, be not easy to drop, and need not specialist tools, changes to make things convenient for; The wear extent of long rake teeth is maximum, but its effective active length can adjust, and does not need often to change parts, practices thrift cost.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of digger chain in the prior art.
Fig. 2 is the mounting means sectional view of rake teeth in the prior art.
Fig. 3 is the structural representation of the utility model digger chain.
Among the figure: 1. the rake palm, 2. intermediate, 3. long rake teeth is 4. lacked rake teeth, 5. hexagon socket countersunk flat cap head screw, 6. locking nut, 7. spring washer, 8.T shape bolt, 9. chain pin, 10. rake teeth, 11. gear rings, 12. straight pins.
The specific embodiment
In Fig. 3, when digger chain is installed, a long rake teeth 3 and three short rake teeths 4 to be packed in the rake teeth installing hole of the rake palm 1, long rake teeth 3 is contained in the top, penetrates hexagon socket countersunk flat cap head screw 5 and harrows the casting counter sink of slapping on 1, tightens with locking nut 6.When adorning long rake teeth 3, soket head cap screw is passed long rake teeth 3 mounting groove foremost, behind long rake teeth 3 leading sections wearing and tearing certain-length; Locking nut 6 is unclamped, release a joint to long rake teeth 3, make hexagon socket countersunk flat cap head screw 5 pass the mounting groove of long rake teeth 3 centres; Its effective active length is increased; By that analogy, after the damage of regrinding, the mounting groove of long rake teeth 3 least significant ends is installed.When changing short rake teeth 4, locking nut 6 is unclamped, will lack rake teeth 4 and take out, change newly, again locking nut 6 is tightened.
After rake teeth assembling is accomplished, intermediate 2 is packed in the mounting groove of the rake palm 1 and aimed at installing hole, insert chain pin 9, tommyhead bolt 8 is packed in the middle of the rake palm 1 in the boss installing hole, compress chain pin 9, put spring washer 7 backs and tighten with locking nut 6.1 and intermediate of the rake palm 2 that rake teeth is housed is formed a joint digger chain.According to the difference of excavating width, the whole piece digger chain is made up of 82 to 86 joints.The whole piece digger chain is installed on the cleaning car, promptly can begins operation.
After the cleaning car stops operation, the locking nut 6 at tommyhead bolt 8 places of arbitrary joint is pulled down, taken out spring washer 7 and chain pin 9, can throw off digger chain.
