Abstract
The invention discloses a buffering oil cylinder of a dynamic compaction machine. The buffering oil cylinder of the dynamic compaction machine comprises a cylinder body (5), wherein an outer piston (8) and an inner piston (3) are arranged inside the cylinder body (5), the outer piston (8) forms a rod cavity (6) and a rod-less cavity (9) inside the cylinder body (5), a damping hole (7) which penetrates through the rod cavity (6) and the rod-less cavity (9) is formed in the outer piston (8), the rod cavity (6) and the rod-less cavity (9) are filled with hydraulic oil (2), the outer piston (8) is connected with a piston rod (1), a spring (4) is arranged between the inner piston (3) and the cylinder body (5), and the cylinder body (5) is provided with an exhaust vent (10) which is communicated with the inner cavity of the spring (4). The buffering oil cylinder of the dynamic compaction machine achieves the effect of greatly consuming counter force of a pounder through a buffer spring and flow of the hydraulic oil in different cavities, and accordingly greatly reduces fatigue damage of the counter force of the pounder to rigid bodies such as a girder and a machine body platform, reduces shaking of a complete machine, especially of the girder, and improves overall stability and security.
Description
Technical field
The present invention relates to a kind of cushion cylinder, particularly relate to a kind of cushion cylinder of dynamic compaction machinery,
The invention still further relates to the mounting structure of the cushion cylinder of this dynamic compaction machinery.
Background technique
According to the feature of dynamic consolidation construction, when hammer ram discharges, its counter-force that dynamic compaction machinery member is produced is severe test to the machine life of professional dynamic compaction machinery, stability and Security.At present, traditional dynamic compaction machinery mostly adopts spring to make damping device, there is member in when buffering shortcomings such as the number of oscillation is more, and stabilization time is long, and To Predict Fatigue Life of Components is low back and forth, therefore, this structure is improved, and when hammer ram is discharged, damping device is the judder energy of absorption component fast and effectively, recover rapidly stable, have great importance.
Summary of the invention
First technical problem to be solved by this invention is to provide a kind of judder energy of absorption component fast and effectively, recovers rapidly the cushion cylinder of stable dynamic compaction machinery.
Second technical problem to be solved by this invention is to provide the mounting structure of the cushion cylinder of this dynamic compaction machinery.
In order to solve first technical problem, the cushion cylinder of dynamic compaction machinery provided by the invention, comprise cylinder body, in described cylinder body, be provided with outer piston and inner carrier, described outer piston is formed with rod chamber and rodless cavity in described cylinder body, described outer piston is provided with and connects described rod chamber and the damping hole of rodless cavity, in described rod chamber and rodless cavity, be filled with hydraulic oil, on described outer piston, be connected with piston rod, between described inner carrier and described cylinder body, be provided with spring, described cylinder body is provided with the exhaust port being communicated with the inner chamber that is provided with described spring.
Described spring is arranged on the bottom of described cylinder body, and described inner carrier is directly pressed in described spring top, and described piston rod is arranged on described cylinder body top.
In order to solve second technical problem, the mounting structure of the cushion cylinder of the dynamic compaction machinery originally providing, the described piston rod of one end of described cushion cylinder is hinged on truss by bearing pin, and the described cylinder body of the other end is hinged on fuselage platform by bearing pin.
The cushion cylinder that adopts the dynamic compaction machinery of technique scheme, the mounting structure of cushion cylinder is: by bearing pin one end, be hinged on truss, the other end is hinged on fuselage platform.When dynamic compaction machinery discharges hammer ram, power moment is by truss role during in piston rod and outer piston, hydraulic oil place rodless cavity volume reduces, form oil pressure, and promote inner carrier Compress Spring, sub-fraction hydraulic oil enters rod chamber by the damping hole on piston rod simultaneously.Spring-compressed is rear resilience to a certain extent, and hydraulic oil continues to enter rodless cavity by the damping hole on piston rod.Hydraulic oil is constantly reciprocal in rod chamber, rodless cavity, loss pressure, thus play buffer function.
Damping spring and hydraulic oil the flowing in different cavitys of cushion cylinder of the present invention by cushion cylinder, realized with very short time and seldom stroke greatly consume hammer ram counter-force.Thereby greatly reduced the fatigue ruption of hammer ram counter-force to rigid bodies such as truss, fuselage platforms; Reduce complete machine, particularly rocking of truss, has improved whole stability and Security.
In sum, the present invention is a kind of judder energy of absorption component fast and effectively, cushion cylinder and the mounting structure thereof that recovers rapidly the dynamic compaction machinery of stable, structural member working life, stability and Security that can effectively improve dynamic compaction machinery.
Accompanying drawing explanation
Fig. 1 is cushion cylinder structural representation of the present invention.
Fig. 2 is use view of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Referring to Fig. 1, in cylinder body 5, be provided with outer piston 8 and inner carrier 3, outer piston 8 is formed with rod chamber 6 and rodless cavity 9 in cylinder body 5, outer piston 8 is provided with the damping hole 7 that connects rod chamber 6 and rodless cavity 9, in rod chamber 6 and rodless cavity 9, be filled with hydraulic oil 2, spring 4 is arranged on the bottom of cylinder body 5, inner carrier 3 is directly pressed in spring 4 tops, piston rod 1 is arranged on cylinder body 5 tops and is connected with on outer piston 8, between inner carrier 3 and cylinder body 5, be provided with spring 4, cylinder body 5 is provided with the exhaust port 10 being communicated with the inner chamber that is provided with spring 4.
Referring to Fig. 1 and Fig. 2, one side of the bottom of truss 13 is hinged on fuselage platform 11, the piston rod 1 of one end of cushion cylinder 12 is hinged on by bearing pin on the opposite side of truss 13, and the cylinder body 5 of the other end of cushion cylinder 12 is hinged on fuselage platform 11 by bearing pin, and truss 13 is provided with hammer ram 14.
Referring to Fig. 1 and Fig. 2, when when dynamic compaction machinery discharges hammer ram 14, power moment acts on piston rod 1 and outer piston 8 by truss 13, hydraulic oil 2 place rodless cavity 9 volumes reduce, form oil pressure, and promoting inner carrier 3 Compress Springs 4, sub-fraction hydraulic oil 2 enters rod chamber 6 by the damping hole 7 on outer piston 8 simultaneously.Resilience after spring 4 is compressed to a certain degree, hydraulic oil 2 continues to enter rodless cavity 9 by the damping hole 7 on outer piston 8.Hydraulic oil 2 is constantly reciprocal in rod chamber 6, rodless cavity 9, and outer piston 8, loses pressure, thereby plays buffer function by hydraulic oil 2 transferring energies with inner carrier 3.Exhaust port 10 will be provided with discharge and the suction of air of the inner chamber of spring 4 when spring 4 compression and resilience on cylinder body 5.
