Description

Technical Field

[0001] The utility model is used in the field of irradiation conveyor lines, and in particular relates to a irradiation conveyor line with a hanger stopping device. Background Art

[0002] A radioactive source is required for irradiation processing. When the radioactive source is in working condition, personnel cannot enter the irradiation room to avoid being irradiated. Usually, a chain conveyor system is used to transport samples from the operating room to the irradiation room. During the production process, according to the relevant irradiation process requirements, the hanger needs to stop at different positions on the conveyor line to be irradiated by the radioactive source. However, in the prior art, when the hanger reaches the predetermined irradiation position, the chain conveyor system needs to be shut down. After the preset irradiation time is reached, the chain conveyor system is started again to send the sample out. The conveying system needs to be started and stopped frequently, which not only has low working efficiency, but also easily damages the main equipment motor and other components in the conveying system. Utility Model Content

[0003] (I) Purpose of the utility model

[0004] The utility model aims to provide an irradiation conveyor line with a hanger stopping device, which can stop the hanger at a fixed position without stopping the conveyor chain according to the requirements of the control system, and open it to release it when it needs to be released. Compared with frequently starting and stopping the conveyor chain to stop the hanger, it is convenient and quick.

[0005] (II) Technical solution

[0006] In order to achieve the purpose of this utility model, the utility model adopts the following technical solutions:

[0007] The structure of the utility model:

[0008] The structure of the utility model: an irradiation conveyor line with a hanger stop device, the irradiation conveyor line comprises a traction track, a load-bearing track, a conveyor chain, a trolley head, a hanger, and a hanger stop device; the traction track is arranged in parallel above the load-bearing track, the conveyor chain is arranged on the traction track and can slide along the traction track, and a push hook is hingedly arranged below the conveyor chain; the trolley head can be slidably arranged on the load-bearing track, and the hanger is fixed below the trolley head; the push hook is in a coupling position that can be coupled with the trolley head in a normal state, and when in the coupling position, the push hook can drive the trolley head to slide along the load-bearing track; the hanger stop device is fixedly arranged on the load-bearing track, and the hanger stop device comprises a fork tongue that can be extended or retracted. If the fork tongue is extended, the push hook will be decoupled from the trolley head when passing through the fork tongue, thereby releasing the trolley head.

[0009] Preferably, the push hook includes a hook-shaped head, a middle protrusion and a tail. The tail of the push hook is hinged on the conveying chain. If the fork tongue is extended, the middle protrusion of the push hook will be lifted up by the fork tongue when the push hook passes through the fork tongue, thereby driving the hook-shaped head to rotate and lift around the hinge axis of the tail to release the trolley head.

[0010] Furthermore, the hanger stopping device also includes a driving component and a bracket, the driving component is fixedly arranged on the bearing rail through the bracket, and the driving component can drive the fork tongue to extend or retract.

[0011] Further, the driving component includes a solenoid valve and a cylinder, and the fork tongue is fixed to the end of the piston rod of the cylinder. Alternatively, the driving component may also include a solenoid valve and a hydraulic cylinder, and the fork tongue is fixed to the end of the piston rod of the hydraulic cylinder. Alternatively, the driving component may also be an electric telescopic rod, and the fork tongue is fixed to the end of the electric telescopic rod.

[0012] Furthermore, the hanger stop devices are provided in plurality and are respectively fixed at different irradiation stations of the bearing rail.

[0013] Furthermore, the hanger is fixed below the trolley head via a pin shaft.

[0014] The working principle of this utility model:

[0015] First, according to the process requirements, the hanger stop device is fixed at the corresponding position on the load-bearing track. During irradiation processing, the goods are placed on the hanger and the hanger is transported by the conveyor line. Because the push hook is usually in a coupling position that can be coupled with the trolley, the push hook on the conveyor chain starts to drive the trolley to slide along the load-bearing track with the operation of the conveyor chain at the beginning, and the hanger is transported forward. According to the actual irradiation process, when the hanger needs to stop at a certain position to wait, the driving component in the hanger stop device at this position is controlled to move, driving the fork tongue to extend and block in front of the trolley. When the push hook passes through the fork tongue, its middle protrusion will be lifted by the fork tongue, thereby driving the hook-shaped head to rotate and lift around the hinge shaft at the tail, releasing the trolley, and then the push hook continues to be driven forward by the conveyor chain, and the trolley stops sliding, and the hanger stops at this position. When it is necessary to release according to the process requirements, the fork tongue of the control hanger stop device is retracted, and the push hook is in a state that can be coupled with the trolley, then the hanger connected to the trolley will be taken away by the push hook and move forward along the conveyor chain again.

[0016] (III) Technical Effect

[0017] Compared with the prior art, the irradiation conveyor line with a hanger stop device of the utility model has the following beneficial and significant technical effects:

[0018] (1) The irradiation conveyor line is equipped with a hanger stop device, so the hanger can be stopped at a fixed position without stopping the conveyor chain according to the process requirements. When it needs to be released, it is opened to release it. Compared with frequently starting and stopping the conveyor chain to stop the hanger, it is convenient and quick.

[0019] (2) According to the actual situation, multiple hanger stop devices can be set, and they can be controlled separately. In addition, multiple hangers can be parked behind the same hanger stop device, and the number can be determined in advance by the process. Through the action of the hanger stop device, dynamic balance is maintained, thereby realizing continuous production. BRIEF DESCRIPTION OF THE DRAWINGS
