Technical field
The utility model relates to hydraulic control and the air control unit on a kind of amusement apparatus, is specifically related to a kind of multifunctional gas-liquid swivel coupling.
Background technique
In general large amusement machine, be all provided with revolution part, as " aviation training device " amusement apparatus, the existing HYDRAULIC CONTROL SYSTEM of power unit wherein, there is pneumatic system to control again, pipe joint by revolution part only has simple hydraulic gyration head or pneumatic rotary head at present, and these two kinds of joints are difficult to meet the demand of hydraulic pressure, pneumatic dual control in " aviation training device " amusement apparatus.In addition, when amusement apparatus power-off, entertainment cabin is suspended in the air, can not decline by hydraulic gyration head or the emergent entertainment cabin of controlling of pneumatic rotary head, also there is no voltage regulation function.
Model utility content
In order to solve the problem that existing hydraulic gyration head or pneumatic rotary camera function are single and be not suitable for using in " aviation training device " amusement apparatus, the utility model provides a kind of multifunctional gas-liquid swivel coupling, this multifunctional gas-liquid swivel coupling becomes one hydraulic channel and pneumatic channel set, have emergent control passenger cabin declines and voltage regulation function simultaneously, simple in structure, be adapted at using in " aviation training device " amusement apparatus.
The technical solution of the utility model is: a kind of multifunctional gas-liquid swivel coupling comprises running shaft core and rotary sleeve, between running shaft core and rotary sleeve, can relatively rotate, the sidewall of rotary sleeve is provided with hydraulic pressure hydraulic fluid port, hydraulic oil-returning mouth and pneumatic port, the outer wall of running shaft core is provided with and hydraulic pressure hydraulic fluid port, hydraulic oil-returning mouth and pneumatic port circular groove one to one, and described circular groove communicates with an end face of running shaft core by the axial bore on running shaft core; Between described hydraulic oil-returning mouth and its corresponding axial bore, be provided with stop valve, on another end face of running shaft core, be fixed with the accumulator being connected with oil hydraulic cylinder lower chambers, in the outlet passage of accumulator, pressure relay is installed.
Described running shaft core and the both sides of the hydraulic pressure hydraulic fluid port between rotary sleeve, hydraulic oil-returning mouth and pneumatic port are equipped with seal ring.
Described hydraulic pressure hydraulic fluid port and hydraulic oil-returning mouth are respectively 2.
The utlity model has following beneficial effect: owing to taking such scheme, hydraulic channel and pneumatic channel set are become one, there is emergent control passenger cabin simultaneously and decline and voltage regulation function, simple in structure, be adapted at using in " aviation training device " amusement apparatus.
Accompanying drawing explanation
Accompanying drawing 1 is structure sectional view of the present utility model.
Accompanying drawing 2 is left views of Fig. 1.
Accompanying drawing 3 is control principle drawings of the present utility model.
1-running shaft core in figure, 2-rotary sleeve, 3-hydraulic pressure hydraulic fluid port, 4-hydraulic oil-returning mouth, 5-pneumatic port, 6-circular groove, 7-stop valve, 8-accumulator, 9-pressure relay, 10-oil hydraulic cylinder, 11-seal ring.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
By Fig. 1 in conjunction with shown in Fig. 2, Fig. 3, a kind of multifunctional gas-liquid swivel coupling comprises running shaft core 1 and rotary sleeve 2, between running shaft core 1 and rotary sleeve 2, can relatively rotate, the sidewall of rotary sleeve 2 is provided with hydraulic pressure hydraulic fluid port 3, hydraulic oil-returning mouth 4 and pneumatic port 5, the outer wall of running shaft core 1 is provided with and hydraulic pressure hydraulic fluid port 3, hydraulic oil-returning mouth 4 and pneumatic port 5 circular groove 6 one to one, and described circular groove 6 communicates with an end face of running shaft core 1 by the axial bore on running shaft core 1; Between described hydraulic oil-returning mouth 4 and its corresponding axial bore, be provided with stop valve 7, on another end face of running shaft core 1, be fixed with the accumulator 8 being connected with oil hydraulic cylinder 10 lower chambers, pressure relay 9 is installed in the outlet passage of accumulator 8.Owing to taking technique scheme, integrated hydraulic channel and the pneumatic channel of being provided with on running shaft core 1 and rotary sleeve 2, make hydraulic control circuit and Pneumatic control circuit can pass through this swivel coupling simultaneously, 8 pairs of oil circuits of accumulator carry out repairing, pressurize, make the piston rod of oil hydraulic cylinder 10 can, because draining moves down, not guarantee that play does not occur in the position of passenger cabin.When amusement apparatus power-off, open stop valve 7, make the hydraulic oil of oil hydraulic cylinder 10 cavity of resorptions flow back to fuel tank by hydraulic oil-returning mouth 4, passenger cabin is steadily declined, passenger safety is withdrawn.When the cavity of resorption overpressure of oil hydraulic cylinder 10, pressure relay 9 detects and feedback signal control oil pump stops, and when the cavity of resorption hypotony of oil hydraulic cylinder 10, pressure relay 9 detects and feedback signal control oil pump starts.The utility model is simple in structure, is adapted at using in " aviation training device " amusement apparatus.
Described running shaft core 1 and the both sides of the hydraulic pressure hydraulic fluid port 3 between rotary sleeve 2, hydraulic oil-returning mouth 4 and pneumatic port 5 are equipped with seal ring 11.Leakage of oil or gas leakage when seal ring 11 effectively prevents from relatively rotating between running shaft core 1 and rotary sleeve 2.
Described hydraulic pressure hydraulic fluid port 3 and hydraulic oil-returning mouth 4 are respectively 2.The present embodiment is optimal way, can certainly be more, and its quantity is determined according to the physical dimension of the quantity of oil hydraulic cylinder 10 and running shaft core 1.
Above-described embodiment, only as optimal way, should not be considered as restriction of the present utility model, and any improvement of making based on Spirit Essence of the present utility model is all within protection of the present utility model.
