Problems solved by technology
The flood discharge channel is more than eight meters away from the bottom of the stilling basin, so inspection and maintenance are very difficult. The slope of the flood discharge channel is above 65°, the length is generally about 100 meters, and the width is about six meters. Therefore, it is necessary to check and maintain the flood discharge channel. , Scaffolding must be erected, not only the workload is heavy, time-consuming, but also very dangerous

The invention discloses a hydraulic spring type flood discharge runner maintenance climbing device. An aluminum alloy main square beam is provided with a hydraulic pump station, a system control unit, a power supply, left upper, middle and lower hydraulic cylinders, left front and back outer guide sleeves, a left flange extension inner guide sleeve, right upper, middle and lower hydraulic cylinders, a right pressure spring, right front and back outer guide sleeves, and a right flange extension inner guide sleeve; left and right fixed plates are provided with left upper and lower universal wheels and right upper and lower universal wheels; left upper and lower T-shaped plates are respectively provided with left upper inner and outer speed reducers with motors, left lower inner and outer speed reducers, left upper inner and outer rubber wheels and left lower inner and outer rubber wheels; right upper and lower T-shaped plates are respectively provided with right upper inner and outer speed reducers with motors, right lower inner and outer speed reducers, right upper inner and outer rubber wheels and right lower inner and outer rubber wheels; and the hydraulic cylinders are communicated with the hydraulic pump station by pushing oil pipes and pull back oil pipes. The technical scheme is widely applied to such fields as flood discharge runners.
Description
[0001] Technical field: [0002] The invention is mainly applied to a device for maintenance and crawling of the flood discharge channel of the dam flood discharge dam section. [0003] Background technique: [0004] The flood discharge dam sections of most hydroelectric power plants have multiple flood discharge channels. During flood discharge, the high-speed water velocity will cause serious erosion damage to the flood discharge channels, which directly affects the safety of the dam parent body. Perform necessary inspections and maintenance. The flood discharge channel is more than eight meters away from the bottom of the stilling basin, so inspection and maintenance are very difficult. The slope of the flood discharge channel is above 65°, the length is generally about 100 meters, and the width is about six meters. Therefore, it is necessary to check and maintain the flood discharge channel. , It is necessary to build scaffolding, which is not only a lot of work, time-cons...
