Problems solved by technology

[0003] The original design made the automation of the entire handling process very low, and the crane driver and personnel related to the handling could not leave the warehouse site and were under the threat of nuclear radiation; due to the original design, the vertical and horizontal travel of the crane and the hook Two-speed motors are used for lifting and lowering, and the braking method is an electromagnet matched with the motor. The brake release voltage adopts the

Example Embodiment

[0026] The preferred embodiments of the present invention are given below and described with reference to the accompanying drawings.

[0027] like figure 1 As shown, a control room 06 is added outside the waste barrel warehouse 01; a laser rangefinder 1 is installed on the wall in the longitudinal (X direction) of the warehouse 01 to monitor the position of the cart 04; on the longitudinal axis of the cart 04 A laser range finder 2 is installed in the direction (Y direction) to monitor the position of the trolley 05; a rotary encoder 3 is installed on the trolley lift motor to monitor the position of the spreader in the vertical direction (Z direction). The vehicle lane camera 6 is installed on the ceiling above the entrance and exit 03 of the waste bin, the omnidirectional camera 5 is installed on the ceiling in the middle of the warehouse 01, and the trolley camera 4 is installed on the trolley 05.

[0028] like figure 2 As shown, a console 11 and a control cabinet 12 are...

Abstract

This invention relates to a high precision positioning and accessing system for waste nuclear material. Wherein, for improvement while keeping original workshop and devices, arranging a frequency-changing system on the dual-speed motor for continual regulation within 0~50Hz; adding a band-brake power controlled by a PLC digital interface for single band-brake release; and measuring position of the sling by two laser rangers and one rotary coder. This invention reduces nuclear radiation to operators and workers and shaking amplitude of the trash receptacle, increases crane position precision to 1mm, and improves warehouse utilization rate.

Description

technical field [0001] A nuclear waste high-precision positioning access system is used in nuclear power plant waste barrel storage. It belongs to the field of nuclear engineering. Background technique [0002] All nuclear power plants have nuclear waste disposal problems. An existing nuclear power plant in my country uses the technology of the former Soviet Union (see ELECTRIC BRIDGE CRANE with LIFTING CAPACITY 6.3t2SMB03AE001 TO TECHNICAL DESCRIPTION). That is to build a waste barrel warehouse with an area of ​​about 70×18m and a height of about 20m. As an exit), so that the vehicles for transportation to and from are parked under the entrance and exit. Waste barrels with a diameter of about 1.5m are stacked in 4 to 6 layers in the warehouse in the form of a triangular array. The handling of waste barrels is completed by a 6.3-ton electric double-bridge crane installed in the warehouse. [0003] The original design made the automation of the entire handling process ve...
