Problems solved by technology
[0007] Waste of resources: After all the grids are introduced, the track needs to be dismembered and cannot be used for the introduction of grids for other projects. It can only be used as waste materials. In addition, the damage to ground tanks during the grid introduction process is extremely great , it is very easy to cause damage and cannot continue to be used, and the purchase price of ground tanks is relatively high, which will cause a large waste of resources

[0056] Description of working principle
[0057] The automatic flipping transport trolley can control the 4 steering wheels by manipulating the wireless, wired industrial remote control or human-machine interface in 3 ways. The driving mode includes forward, backward, 180° translation, left turn, right turn. The travel speed is 0-20m / min for heavy load and 30m / min for no-load according to the requirements, and the speed can be adjusted. Select low speed, medium speed and high speed mode by switching the 3-speed switch. Control the forward and backward of the trolley by pushing and pulling the left joystick. The joystick has five gears, and each of the three speed modes can be adjusted in five gears.
[0058] The mobile platform truck adopts diagonal drive, and at the same time, there is a steering bridge in front of the vehicle body. The steering bridge is connected with the vehicle body through the rocker structure. When the ground is uneven, the rocker structure can reach...

The invention belongs to a moving system, and particularly relates to an automatic moving system of a spent fuel storage grillwork for a nuclear island fuel plant. A spent fuel storage grillwork automatic moving system for a nuclear island fuel plant is characterized by comprising a driving part which is used for driving the automatic moving system to move; the control system is used for controlling the whole system; the safety system is used for emergency braking, sound-light alarm, safety edge contact, radar detection and operation locking functions; and the power system is used for providing energy for the whole system. The moving mechanism has the remarkable effects that the moving mechanism is applied to the lower surface of a spent fuel storage grillwork and is used for realizing automatic moving and walking when the grillwork is introduced.
Description
technical field [0001] The invention belongs to a mobile system, in particular to an automatic mobile system for a spent fuel storage rack used in a nuclear island fuel plant. Background technique [0002] The existing spent fuel storage rack for nuclear island fuel plant is a standard fixed structure. In the process of transporting spent fuel, based on the structural characteristics of the spent fuel storage rack in the nuclear island fuel plant and the limitations of the fuel plant environment It needs manual handling, which not only has low work efficiency, but also wastes a lot of human, material and financial resources. More seriously, there are great quality and safety risks. The unfavorable factors are as follows: [0003] Occupying the site for a long time: The 0-meter channel and hoisting holes in the K area are an important way to introduce all equipment in the K area. During the introduction and flipping of the grid, the rails need to be fabricated, welded, asse...
