Description
Technical field
This utility model relates to dynamic compaction machinery technical field.
Background technology
Dynamic compaction machinery is that the material brute force of the better performances such as rubble, slabstone, slag can be clamp-oned and carries out compaction treatment in ground by HI high impact repeatedly that utilize hammer ram height drop to produce, ground is formed pellet pier one by one, soil form compound foundation between pier and pier, to improve foundation bearing capacity, reduce sedimentation, dynamic compaction machinery extensive use in architectural engineering, in reclamation.
Dynamic compaction machinery is in the course of the work, owing to hammer ram is in free falling body state after unhook, and the working environment of dynamic compaction machinery is varied, there are the working sites such as sand ground, marsh, hills, seabeach, therefore after hammer ram lands, probably will not with suspension hook in same vertical level, have certain side-play amount, thus arm is produced oblique loading, hoist in process at secondary hook, by adjustment slew gear, this side-play amount will be adjusted, to prevent from jib is produced oblique loading, the accident causing dynamic compactor arm frame to fracture or turning on one's side.Traditional dynamic compaction machinery Hydraulic slewing system requires over pilot handle to adjust this side-play amount, if side-play amount is big, pilot handle can also adjust side-play amount, if side-play amount is little, depend merely on pilot handle to be difficult to adjust, and process in also can increase the energy consumption of system, increase the complexity of user operation, reduce work efficiency.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
Embodiment 1
A kind of dynamic compaction machinery revolution hydraulic control system, it is characterised in that include drum pump 1, rotary buffering valve 2, rotary motor 6, brake 7, Rotatary brake valve 8 and servopump 9；Described drum pump 1 is connected with rotary buffering valve 2, and rotary buffering valve 2 includes gyratory directions and controls valve 3, overload valve 4, trimmer valve 5；Hydraulic oil through drum pump 1 enters the gyratory directions in rotary buffering valve 2 and controls valve 3, and gyratory directions controls valve 3 and realizes commutation by the input of handle signal 10；Rotary motor 6 is driven by hydraulic oil, and servopump 9 enters brake 7 through Rotatary brake valve 8, it is achieved the control to rotary motor 6, and rotary motor 6 makes rotary table rotate or stops.
Further technical scheme, described rotary buffering valve 2 includes Y1 electromagnetic valve 11, and Rotatary brake valve 8 includes Y2 electromagnetic valve 12, Y1 electromagnetic valve 11 and the Y2 electromagnetic valve 12 free rotary within drivers' cab by key control, can simultaneously electric commutation.
Further technical scheme, it is pilot operated directional control valve that described gyratory directions controls valve 3.
Its revolution hydraulic control system loop works principle is as follows: enters the gyratory directions rotary buffering valve 2 from the hydraulic oil of drum pump 1 and controls valve 3, it is pilot operated directional control valve that gyratory directions controls valve 3, input by handle signal 10, make gyratory directions control valve 3 and realize commutation, so that hydraulic oil drives rotary motor 6, servopump 9 enters brake 7 through Rotatary brake valve 8 simultaneously, it is made to release the restriction to rotary motor 6, the moment of torsion that rotary motor 6 produces, through reductor, engages with the bull gear of pivoting support make rotary table rotate by turning round little gear.
When needing the side-play amount between hammer ram and jib is adjusted, press the free rotary button within drivers' cab, now the Y2 electromagnetic valve 12 of the Y1 electromagnetic valve 11 of rotary buffering valve 2 and Rotatary brake valve 8 simultaneously electric commutation.After Y2 electromagnetic valve 12 commutation, the hydraulic oil of servopump 9 is not when having handle signal, it is also possible to enters brake 7 by Y2 electromagnetic valve 12, relieves the brake 7 restriction to rotary motor 6；Owing to brake 7 has already turned on, Y1 electromagnetic valve 11 also commutates, the oil-feed side of rotary motor 6 is identical with oil extraction side and oil return opening, low pressure revolution done by rotary motor 6 under the effect of load side force, until rotary motor 6 both sides oil pressure balance, load side force disappears, and arm and hammer ram are in same vertical level, reaches the desirable operating mode before lifting.
This utility model design is simple, easy to operate, with low cost, this revolution hydraulic control system compares traditional control technology, simplify the adjustment process of side-play amount, improve the operating power consumption of the work efficiency of dynamic compaction machinery Hydraulic slewing system, the workload of minimizing operator, reduction hydraulic control system, improve the utilization rate of energy, extend the service life of equipment.
