Abstract
The utility model relates to a device used to lift a radiation source in a Gamma radiation device, which is a pneumatic cobalt source lifter. It uses a steel wire traction source rack to lift. A steel wire is wound between a crown block group and a traveling block group. The traveling block group is connected to the end of the piston rode of the cylinder. The cylinder is connected with a pneumatic control loop. The source rack is lifted by movement of the cylinder piston. The utility model provides a lifting source through cylinder driving method. In security and stability for long-time running, it is comparable to hydraulic pressure driving lifting source. Moreover, it can further ensure the security of the lifting source with characteristics of pneumatic loops. The system structure is simple and easy for inspection and maintenance. Additionally, the utility model can use same pneumatic source with the product feeding system of Gamma radiation devices in which pneumatic propelling are increasing popular today.
Description
Technical field
The utility model relates to a kind of device that is used at Dynarad lifting radioactive source.
Background technology
Cobalt source jacking gear is the nucleus equipment in the commercial Dynarad, and its effect is the working position that cobalt-60 radioactive source is promoted to the irradiation space from the well of storage source, when irradiation production finishes, radioactive source is rolled back reposefully safe storage position under water again.When meeting any emergency condition, radioactive source can fall back to the well automatically from the working position.The security function of this equipment and long-time running reliability are to be directly connected to the key link of being engaged in RADIATION PROCESSING producers personal safety.
Cobalt source jacking gear before this adopts electronic elevator mode mostly, and part adopts hydraulic driving mode.The former usage ratio maximum, its major defect is that it is in a single day malfunctioning to be used for the spacing travel switch in lifting source, motor can drive the hoisting cable cylinder and continue rotation, cause source frame over travel, can break wire rope or the source of damage frame when serious, might lead to the major accident that source rod is scattered.In addition, the source function falls in power failure automatically that be difficult to realize ideal, thereby the security deficiency.Though the hydraulic pressure cobalt source jacking gear that gradually adopts has in recent years overcome the above-mentioned defective of motor hoisting equipment, its system itself is comparatively complicated, and also often there is oil leakage phenomenon in oil hydraulic system, and its components and parts are safeguarded and changed maintenance personal's technical ability requirement also higher.
Summary of the invention
The purpose of this utility model is to provide a kind of system simpler at the weak point of existing cobalt source jacking gear, and safer, reliable pneumatic cobalt source jacking gear.
The technical solution of the utility model is as follows: pneumatic cobalt source jacking gear is by hoisting cable traction source frame, wire rope is wrapped between fixed pulley group and the running block, running block is connected with the piston rod end of cylinder, cylinder connects Pneumatic control circuit, by the motion of cylinder piston, drive the source frame and rise and descend.
Aforesaid pneumatic cobalt source jacking gear wherein, is provided with filtrator, reduction valve, oil sprayer, solenoid valve successively on Pneumatic control circuit.
Aforesaid pneumatic cobalt source jacking gear wherein, is provided with flow speed control valve between cylinder and solenoid valve.
The utility model adopts the air cylinder driven mode to realize the lifting source, not only has the reliability with identical security function in hydraulic-driven lifting source and long-time running, can utilize the characteristics of gas circuit simultaneously, the safety assurance that improves the lifting origin system.And system is also more simple, is convenient to examination and maintenance.In addition, the product delivery system of current Dynarad adopts pneumatic propulsion mode more and more, and the utility model can use same source of the gas very easily.This device and prior motor drive cobalt source jacking gear and compare, and stopping source frame over travel accident and realizing that power failure falls automatically and reliable assurance has been arranged aspect the security such as source, are particularly suitable for using in the Dynarad of air compression system is arranged.
Description of drawings
Fig. 1 is the structural representation of pneumatic cobalt source jacking gear.
Among the figure, 1. mechanical interlock mechanism 2. stop valves 3. strainer valves 4. reduction valve 5. oil sprayers 6. solenoid valves 7. solenoid valves 8. flow speed control valves 9. cylinders 10. running blocks 11. wire rope 12. fixed pulley groups 13. source framves 14. source wells
Embodiment
As shown in the figure, pneumatic cobalt source jacking gear is by hoisting cable 11 traction source framves 13, wire rope 11 is wrapped between fixed pulley group 12 and the running block 10, running block 10 is connected with the piston rod end of cylinder 9, cylinder 9 connects Pneumatic control circuit, by the motion of cylinder 9 pistons, drive source frame 13 and rise and descend.Enter by mechanical interlock mechanism 1 from the pressurized air of source of the gas and to rise the source pneumatic control circuit, arrive solenoid valve 6,7 via filtrator 3, reduction valve 4, oil sprayer 5, when solenoid valve is switched on, connect gas circuit, pressurized air enters the rod chamber that rises the source cylinder by flow speed control valve 8, the cylinder rod withdrawal, the source frame rises, and when solenoid valve cuts off the power supply, relies on source frame deadweight that the pressurized air in the cylinder rod chamber is discharged, cylinder rod stretches out, and the source frame descends.The speed in lifting source can conveniently be adjusted by flow speed control valve.In addition, in Pneumatic control circuit, can utilize mechanical interlock mechanism to cut off the major loop source of the gas, discharge the method that rises source cylinder residual gas simultaneously, the source frame of making can not accident be raised or in case of emergency falls the source automatically.This function does not rely on electrical signal, under the malfunctioning situation of other electric protections, still can bring into play the safeguard protection effect.
