Check device, falling prevention locking mechanism and fall prevention method
The invention relates to water conservancy and hydropower engineering, in particular to a check device, a falling prevention locking mechanism and a fall prevention method. The check device comprisesa girder, a first compression block and a support part. The first end of the girder is hinged to the first compression block through a first rotary shaft. One end of the support part is connected withthe girder. The other end of the support part is hinged to the first compression block. The first compression block protrudes from the first end of the girder and the end of the support part. When the first compression block rotates forwards around the first rotary shaft, the distance by which the first compression block protrudes from the first end is reduced. When the first compression block rotates reversely around the first rotary shaft, the distance by which the first compression block protrudes from the first end is increased. The support part is used for providing thrust for the firstcompression block, so that the first compression block compresses a channel, and the support part can stretch or retract along rotation of the first compression block. The falling prevention locking mechanism and the fall prevention method are both based on the check device. The check device is simple in structure and high in reliability.
本发明涉及水利水电工程，特别是一种止回装置、防坠锁定机构及防坠方法。止回装置包括主梁、第一压紧块和支撑件；主梁的第一端与第一压紧块通过第一转轴铰接；支撑件一端与主梁相连，支撑件另一端与第一压紧块铰接；第一压紧块由主梁的第一端和支撑件端部向外凸出；第一压紧块绕第一转轴正向转动时，第一压紧块凸出于第一端的距离减小；第一压紧块绕第一转轴反向转动时，第一压紧块凸出于第一端的距离增大；支撑件用于对第一压紧块提供推力，以使第一压紧块压紧通道，且支撑件能够随第一压紧块的转动伸出或缩回。防坠锁定机构和防坠方法均基于上述的止回装置。本发明的装置结构简单、可靠性高。
