Specific embodiment:
Below with reference to embodiment, the invention will be further described, and purpose, which is only that, more fully understands the content of present invention, because
This, the cited case is not intended to limit protection scope of the present invention.
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, one kind taking off panel assembly, including takes off plate 5, takes off on the lower position of plate 5 and is provided with chain
Hole 2 is connect, each plate 5 of taking off can be chained up by intermediate chain fishplate bar 3 and link pins 4, that takes off plate 5 takes off facies palmaris in concave configuration
1, the back for taking off facies palmaris is equipped with grilled teeth mounting hole 9, is provided with grilled teeth in grilled teeth mounting hole 9.
The head of grilled teeth, which is stretched out, takes off the setting of plate 5, and grilled teeth is prominent to take off metacarpus position front end certain distance L, carries out hardened, closely knit road
Quarrel it is pre- loose, effectively reduce and metacarpus position is taken off as large area directly act on larger effect caused by hardened, closely knit ballast
Power.
Grilled teeth is obliquely installed to the facies palmaris of taking off for taking off plate 5, grilled teeth and take off the palm 1 plane of concave configuration between be equipped be suitble to lean forward
Angle can be effectively reduced and take off plate 5 in forward downward to when movement, active force suffered by grilled teeth extension end.
The stop block 8 being provided with for limiting the minimum installation site of grilled teeth is taken off on plate 5.
Grilled teeth includes the first grilled teeth 7 and the second grilled teeth 12, and the first grilled teeth is diamond structure 15, and the second grilled teeth 12 is cylinder
Structure, diamond structure 15 can increase grilled teeth to hardened, closely knit breaking capacity, reduce the active force generated in operation process.
Wearable overlay 14,15 table of diamond structure are provided on two adjacent surfaces of the diamond structure 15 of the first grilled teeth 7
The wear-resisting layer shell of surface build-up welding is effectively to extend the service life of 7 vulnerable part of the first grilled teeth under the premise of reducing cost.
The tail portion of first grilled teeth 7 is provided with multiple locating slots 10, is also provided in the grilled teeth mounting hole 9 of corresponding first grilled teeth 7
There is locating slot 10, the first grilled teeth 7 is fixed in grilled teeth mounting hole 9 by adjusting positioning pin 11, using adjustment positioning pin 11 by the
One grilled teeth 7 is locked in different job positions, can be able to extend 7 service life of the first grilled teeth under the premise of facilitating adjustment
2-3 times.
The head working face of first grilled teeth 7 is inclined surface 13, for reducing the head frictional force in operation.
Second grilled teeth 12 of cylindrical structure, as D is set to the right positions of the first grilled teeth 7, operation to shown in Fig. 3
When be located at railway roadbed bottom, for excavating the harder ballast in railway roadbed bottom, therefore, the second grilled teeth 12 be cylindrical structure, second takes off
It is provided with locating slot 10 on the medium position of tooth 12 and is fixed in corresponding grilled teeth mounting hole 9 by adjusting positioning pin 11, the
It is the rotatable cooperation in gap between two grilled teeth 12 and corresponding grilled teeth mounting hole 9, realizes the second grilled teeth 12 in the effect of operation power
Under revolution, reach uniform wear, prolong the service life, the head of the second grilled teeth 12 studs with antifriction alloy head 16, effectively to prolong
The service life of the long element.
When taking off plate 5 and moving under driving force effect to the direction A, grilled teeth extension end touches harder ballast accumulation first
Object, realizes loose to ballast deposit, and when taking off that plate 5 is whole to push ahead along the direction B, the concave configuration 1 for taking off the palm is then contacted
By loose ballast, by digger chain, realize that facies palmaris is being taken off in the excavation of ballast below sleeper, the setting of the first grilled teeth 7 along the direction A
Back 6 grilled teeth mounting hole 9 in, the tail portion of the first grilled teeth 7 is provided with multiple locating slots 10, using adjustment positioning pin 11 by first
Grilled teeth 7 is locked in different job positions, can when the head extension end length of the first grilled teeth 7 is worn down to certain limit
It is inserted by adjusting positioning pin 11 in next positioning groove 10 of first grilled teeth, 7 tail portion, realizes the first grilled teeth 7 relative to taking off plate 5
Be raised above, increase the head extension end length of the first grilled teeth 7, guarantee the thickness of the loose work layer of grilled teeth, it is straight to prevent from taking off plate 5
Promotion is connect without loose ballastway, generates unreasonable excess force that, the head working face of the first grilled teeth is inclined surface, is used
In reducing the head frictional force in operation, the second grilled teeth 12 is cylindrical structure, and middle part also is provided with locating slot 10, the second grilled teeth 12
Be clearance fit between the grilled teeth mounting hole 9 taken off on plate 5, realize in operation process, the revolution of the second grilled teeth 12 and uniformly mill
Damage is equipped with certain forward leaning angle α, is taking off plate 5 between the first grilled teeth 7 and the second grilled teeth 12 and the plane for taking off facies palmaris concave configuration 1
Upper design has stop block 8, for limiting the extreme lower position of the first grilled teeth 7 and the second grilled teeth 12.
The configuration of the present invention is simple, structural stability is strong, can be effectively reduced processing cost, prolongs the service life.
The foregoing is merely preferably feasible embodiment of the invention, not thereby limiting the scope of the invention,
It is all to use equivalence changes made by description of the invention and its accompanying drawing content, it is intended to be included within the scope of the present invention.
