Problems solved by technology

[0002] In the process of mechanical transmission, when the object to be conveyed is deformed or its appearance is damaged, it may have an adverse effect on the subsequent processing flow, or even impact and damage the equipment downstream of the conveying system. Therefore, it is necessary to monitor the shape of the object to be conveyed
For some situations that require high precision or require remote automatic control, observation through human eyes is not accurate and convenient enough, and it increases the workload of personnel, cannot realize automatic control, and has low efficiency

Embodiment Construction

[0013] In this embodiment, the content of the above invention is further described in conjunction with the limiting door frame used in the delivery system of the barreled nuclear waste neutron detection device.

[0014] The object to be transported in this transmission system is a radioactive nuclear waste barrel. When the waste barrel is deformed, it may hit the detection device, causing damage to the detection device, and there is a risk of radioactive waste leakage. The shape of nuclear waste bins is monitored.

[0015] The limiting door frame provided in this embodiment includes a top frame 1 and left and right columns 2, on which a top frame travel switch 5 and a column travel switch 8 are respectively installed as limit switches. The limit door frame is fixed on the transmission system of the barreled nuclear waste neutron detection device through the bottom plate 10 . The lower part of the top frame 1 is equipped with a rotating plate 3, and the rotating plate 3 is con...

Abstract

The invention belongs to the technical field of limiting devices, in particular to a limit doorframe. The limit doorframe comprises a top frame and a left upright column and a right upright column. A travel switch is respectively arranged on the top frame and the left upright column and the right upright column to serve as a limit switch. A rotating plate is arranged on the lower part of the top frame, and is connected with the top frame through a hinge. The rotation of the rotating plate can move a probe of the travel switch on the top frame, so that the travel switch on the top frame is triggered to output a signal to a control system. A rotating rod is arranged on the inner side of each upright column and connected with a pin shaft. A probe of a travel switch of each upright column is inserted into a bayonet of the pin shaft. The rotating rod rotates to drive the pin shaft to transversely rotate to move the probe of the travel switch of each upright column, so that the travel switch of each upright column is triggered to output a signal to the control system. The limit doorframe can accurately automatically monitor the appearance of a transmitted object.

Description

technical field [0001] The invention belongs to the technical field of limit devices, and in particular relates to a limit door frame, in particular to a limit door frame in a transmission system of a drum-packed nuclear waste neutron detection device. Background technique [0002] In the process of mechanical transmission, when the object to be conveyed is deformed or its appearance is damaged, it may have an adverse effect on the subsequent processing process, and even impact and damage the equipment downstream of the conveying system. Therefore, it is necessary to monitor the shape of the object to be conveyed. For some situations that require high precision or require remote automatic control, observation by human eyes is not accurate and convenient enough, and it increases the workload of personnel, cannot realize automatic control, and has low efficiency. Contents of the invention [0003] (1) Purpose of the invention [0004] The purpose of the invention is to real...
