Abstract

A coaxiality measurement device for mounting of a vertical shaft steel lining of a hydraulic floating vertical ship lift comprises a measurement instrument and a detection work platform. In the measurement instrument, a fixed hole plate is mounted in the design center of a steel lining bottom plate, and a floater, a press plate and a connecting rod are connected to form a whole and then placed in a floating bucket; and the detection work platform is composed of multiple layers of connected work platform bodies, and in each work platform body, one end of each of 16 stud ejector rods equally dividing the circumference into 16 parts is connected with a center support, and the other end of each stud ejector rod is matched with the inner wall of a vertical shaft steel lining joint. According to the coaxiality measurement device and detection method for mounting of the vertical shaft steel lining of the hydraulic floating vertical ship lift, the problems that the workload is large, and precision is not high can be solved; operation is easy and convenient, the detection workload is reduced, and the construction progress is accelerated; and the detection precision of the measuring range being 50 m or above is not larger than 0.5 mm.

Description

technical field [0001] The invention relates to the field of installation of hydraulic vertical ship lift equipment, in particular to a coaxiality measuring device and detection method for installing the steel lining of a vertical shaft of a hydraulic floating vertical ship lift. Background technique [0002] The hydraulic vertical ship lift of Jinghong Hydropower Station is a new type of ship lift with independent intellectual property rights in my country. Its drive uses the water level difference between the upstream and downstream of the dam as the power, converts the potential energy of the water into mechanical energy, and drives the ship to move up and down vertically. , the 16 sets of buoy balance weights are immersed in the water in the corresponding shaft steel lining at a certain submersion depth to achieve full balance with the weight of the ship’s tank. Down or up, through the synchronous rotation of the mechanical lifting equipment, the ship-bearing compartment g...
