3 bearing blocks, 3 bearings are separately fixed on bearing block from top to bottom for setting, and upper and lower bearing block and bearing are hanging down
Histogram is aligned upwards, and uppermost bearing block side is provided with union piece, and pressure sensor is arranged in the side of middle bearing bracket,
The pulley for passing through hawser is provided in 3 bearings, hawser passes through pulley and forms obtuse angle at the pulley of middle bearing bracket, with
Pressure is applied to pressure sensor, the pressure sensor is strain-type, and hawser, which passes through pulley, passes middle bearing bracket to pressure
Deformation occurs for sensor pressure, is converted into cable tension.
Preferably, the bearing is zanjon ball-type.
Preferably, the rear cover of the pressure sensor is connected on compressive cabin, is sealed with watertight part.
