Technical field
The present invention relates to a kind of speed change gear, especially a kind of transportation dual-rail variable speed device of irradiating trolley that is applied to accelerator irradiation field.
Background technology
In the prior art, in the prior art, electron accelerator dolly irradiation devices are monorail mode of movements.Principal mode is made up of the two hinged chains of a very long coarse pitch, the crooked closed orbit of ground pit type, drive unit and parts such as chain swelling device and radiation trolley; Closed orbit is the totally-enclosed track that extends to the outside from radiation chamber; At radiation chamber outside installing drive device and swelling device; The irradiation goods are placed on the radiation trolley; Drive radiation trolley by the two hinged chains of the coarse pitch in the track and move to radiation chamber, carry out irradiation through accelerator titanium window below.
Because of the protection reason; The radiation trolley track generally is the track of many group curved shapes, bumps in the traveling process of curved track for avoiding radiation trolley, and the method that prior art adopts is to be fixed on radiation trolley on the two hinged chains of coarse pitch by a determining deviation; Space type continuous irradiation is arranged; Because can't eliminate the spacing between the radiation trolley in the course of conveying, the accelerator line between the radiation trolley spacing is wasted, and causes energy loss.
Therefore, for reducing the waste of line, energy efficient; Another irradiation track then should be set in irradiation zone, and then the existence owing to the irradiation track can realize therefore radiation trolley is continuously apart from irradiation, in the electron accelerator irradiation process; The irradiation chain travelling speed of irradiation track obviously is lower than conveyer chain; And be to accelerate irradiation speed, then need accelerator irradiation to finish after, can radiation trolley be transported out radiation chamber through conveyer chain.
Summary of the invention
The present invention is directed to the deficiency of prior art; A kind of dual-rail variable speed device of irradiating trolley is provided, on the track of friction speed, carries, on high-speed track, carry thereby solve radiation trolley to realize radiation trolley; And on the low speed track, carry out irradiation; Spacing between the radiation trolley when promptly shortening irradiation reduces the waste of electron accelerator line, energy efficient effectively.
For realizing above technical purpose, the present invention will take following technical scheme:
A kind of dual-rail variable speed device of irradiating trolley; Relate to radiation trolley, high speed carrier chain and low speed irradiation chain; Said high speed carrier chain is installed in the high speed delivery track; Low speed irradiation chain then is installed in the low speed irradiation track, and said speed change gear comprises the rapid transit kinematic pair that is arranged between radiation trolley and the high speed carrier chain, the exchange mechanism that is arranged at the low speed irradiation kinematic pair between radiation trolley and the low speed irradiation chain and radiation trolley is exchanged between rapid transit kinematic pair and low speed irradiation kinematic pair.
Said rapid transit kinematic pair comprises and is fixedly mounted on the telescopic dead man mechanism in dolly bottom and is fixedly installed on the pushing block on the high speed carrier chain; Said low speed irradiation kinematic pair comprises the push jack that is fixedly set in the radiation trolley bottom and is fixedly installed on the push rod on the low speed irradiation chain; But said exchange mechanism comprises lifting dead man mechanism to destroy the dead man lifting mechanism that the rapid transit kinematic pair forms low speed irradiation kinematic pair simultaneously, and said dead man lifting mechanism is arranged near the high speed delivery track cover plate the low speed irradiation track initiating terminal.
Said exchange mechanism comprises also and presses down dead man mechanism to destroy the dead man press mechanism that low speed irradiation kinematic pair forms the rapid transit kinematic pair simultaneously that this dead man press mechanism is arranged near the high speed delivery track cover plate the low speed irradiation track clearing end.
Dead man mechanism comprises the dead man tube, is movably set in the dead man in the dead man tube and makes the dead man location be arranged at the tightening device in the dead man tube; Said dead man tube is fixedly connected on the radiation trolley bottom, and fixedly installs the dead man push-and-pull portion that touches mutually with dead man press mechanism and dead man lifting mechanism that is useful on the dead man.
Said dead man lifting mechanism is the lifting voussoir, and the dead man press mechanism then is the decline voussoir.
Said tightening device comprises tight fixed bolt, steel ball and the spring that tight fixed bolt is connected with steel ball, and said tight fixed bolt is located by connecting on the dead man tube.
Said dead man push-and-pull portion comprises an axle card and a bearing, and bearing is connected on the dead man through axle fastening position.
Be socketed with protective sleeve near the said dead man lower end the body of rod.
According to above technical scheme, can realize following beneficial effect:
Because the present invention fixedly installs dead man lifting mechanism and dead man press mechanism respectively on the initiating terminal of low speed irradiation track and near the high speed delivery track cover plate the clearing end; Then when radiation trolley is transported to the dead man lifting mechanism through dead man along with the traction of high speed carrier chain, because the dead man lifting mechanism through the lifting effect to dead man push-and-pull portion, will make dead man break away from the high speed carrier chain; Promote radiation trolley by the push rod that fixedly installs on the low speed irradiation carrier chain and transport and change; To accomplish the irradiation of electron accelerator, then, when radiation trolley arrives at the dead man press mechanism along with the promotion of low speed irradiation chain; Because the dead man press mechanism suppressing action that push-and-pull applies to dead man; Make dead man move down, until inserting the high speed carrier chain again, so that radiation trolley is transported out radiation chamber along the dead man tube.
