Description
Technical field
The present invention relates to a kind of track linkage supporting arrangement, belong to dynamic compaction machinery technical field.
Background technology
Dynamic compaction machinery is a kind of Foundation Treatment machinery, and by the way that hammer ram lifting is arrived into specified altitude assignment, then Condition of Sudden Unloading is rammed
Hammer, the closely knit ground of the impulsive force of hammer ram, shock wave improves foundation capability.Dynamic consolidation construction has load factor high and frequently unexpected
The features such as unloading, often ramming once can all bring the vibrations of rocking of arm support, and the large-amplitude sloshing of arm support can cause main arm structure part, revolution
Mechanism is damaged, the reduction of complete machine service life, influences construction speed, construction cost is greatly increased.
In order to solve the above technical problems, a kind of track linkage supporting arrangement is provided in the prior art, including：Guide rail, leads
Rail has directive wheel, and the main shaft of directive wheel is arranged on axle block, and axle block is arranged on support frame by bolt, support frame
Two ends are hinged on body cradle.During work, dynamic compaction machinery release hammer ram is freely fallen, and recoil strength is acted on strong rammer platform by strong rammer arm
On, therewith, strong rammer platform is by recoil strength acting rails；Recoil strength is decomposed and passes to ground, axle block and support frame by guide rail
Between be provided with several adjusting pads, cushion stroke is controlled using the change of adjusting pad quantity, so as to control buffer distance.Guide rail
Contacted with directive wheel, the impulsive force of complete machine platform is passed into support frame when complete machine discharges impact energy, support frame again will impact
Power is given on the body cradle at left and right two ends.Body cradle is connected by bolt with left and right crawler attachment, and most impulsive force passes through shoe at last
Belting passes to ground.
It is disadvantageous in that：
1st, error accumulation is easily caused guide rail in processing, assembling process and directive wheel is interfered；
2nd, after hammer ram is sling, vehicle leans forward phenomenon, and now strong rammer platform can be upturned deformation, and guide rail and strong rammer
Platform is synchronous, and this gap resulted between guide rail and directive wheel becomes big, and the gap that now reduce between the two is accomplished by manually
The connecting bolt of axle block and support frame is pulled down, and increases adjusting pad to adjust gap between the two, operability and convenience
Difference.
The content of the invention

A pair of oil cylinder roller 1b, this pair of oil cylinder roller 1b share same roller shaft, and jacking cylinder 1a piston rod is connected to roller shaft
Middle position.As shown in figure 4, jacking cylinder mechanism 1 is provided with three groups, the top of every group of jacking cylinder mechanism 1 is all connected with
There is ring flange, jacking cylinder mechanism 1 is connected by the bolt through ring flange with connecting plate 4, and connecting plate 4 is welded with strong rammer platform 5
Connect, connecting plate 4 is in the frame-type that Open Side Down.
As shown in figure 5, being the structural representation of supporting guide, supporting guide two ends open up flange hole respectively, for branch
Support arrangement 3 is connected, as shown in fig. 6, being the structural representation of support meanss 3.Support rails 2 are provided with accommodating oil cylinder roller 1b's
Roller groove 2a, roller groove 2a are in the rectangle of opening upwards, and opening is between two parties and A/F is less than the upper length of side of rectangle.Support rails
2 outer surface is provided with some stiffener plate 2b.
It is connected with jacking cylinder 1a for controlling jacking cylinder 1a to change coordinated signals between free cylinder and rigid cylinder
System.As shown in fig. 7, coordinated control system includes：One three-position four-way electromagnetic directional valve 6, Bidirectional balanced valve 7, one
Two-position four-way solenoid directional control valve 8；Three-position four-way electromagnetic directional valve 6 uses y-function, its A mouthfuls with Bidirectional balanced valve 7V2 mouthfuls be connected
The rodless cavity with jacking cylinder 1a is connected afterwards, B mouthfuls be connected with 7V1 mouthfuls of Bidirectional balanced valve after rod chamber phase with jacking cylinder 1a
Connection；The A mouths of two-position four-way solenoid directional control valve 8 are connected with jacking cylinder 1a rodless cavity, and B mouthfuls have with jacking cylinder 1a
Rod cavity is connected；The T mouths of three-position four-way electromagnetic directional valve 6, the T mouths of two-position four-way solenoid directional control valve 8 and P mouthfuls connect with fuel tank
Connect.When jacking cylinder 1a is operated in free cylinder state, the no power of three-position four-way electromagnetic directional valve 6, two-position four-way solenoid directional control valve 8
Be powered, now A mouths of two-position four-way solenoid directional control valve 8, B mouthfuls while connected with fuel tank, jacking cylinder 1a piston rod can be free
It is flexible.When jacking cylinder 1a is operated in rigid cylinder state, the no power of two-position four-way solenoid directional control valve 8, for 3-position 4-way electromagnetism
Reversal valve 6：When the Y1a control ends of three-position four-way electromagnetic directional valve 6 obtain electric, the A mouths of three-position four-way electromagnetic directional valve 6 and P mouthfuls
Connection, forms the oil circuit of V2 mouthfuls-balanced valve of P mouthfuls of-A mouthfuls-balanced valves C2 mouthfuls-jacking cylinder 1a rodless cavities, realizes jacking cylinder 1a
