(3) After the sluice is successfully put down, before the hoist is submerged, the buoyancy tank type mounting bracket is fixed on the shore through an ultra-high-strength polyethylene cable or is connected with a winch fixed on the shore, and a steel wire rope connected with the hoist and the sluice is cut off;
(4) In the water level rising process, all air bags are filled with air by using an air compressor in a manual or automatic control or remote control mode;
(5) After the hoist is submerged, the steel buoyancy tank is automatically separated from the fixed part of the basin-type rubber support under the buoyancy of water, the whole hoist is floated on the water surface, and after the water level is stable, the hoist and the buoyancy tank type mounting bracket which float in the water are pulled to the shore by the shore winch through the ultra-high-strength polyethylene cable.
8. The method for recycling hoist as claimed in claim 7, wherein: the concrete bent column is provided with four rectangular supports, the rectangular supports are distributed, the floating box type mounting support is a rectangular mounting frame, the upper support plate and the lower support plate are rectangular metal plates with rectangular through holes in the middle, the steel floating box is of a hollow rectangular structure formed by enclosing four strip-shaped steel box bodies, the upper support plate and the lower support plate are respectively welded on the upper surface and the lower surface of the steel floating box, the hollow parts are communicated with the rectangular through holes in the upper support plate and the lower support plate, the basin-type rubber supports are respectively arranged at four corners of the steel floating box, after the hoist is mounted, steel ropes of the hoist penetrate through the through holes in the middle of the floating box type mounting support and are connected with a gate, and when the hoist is dismounted, the steel ropes are directly sheared.
9. The method for recycling hoist as claimed in claim 7, wherein: when the buoyancy tank type mounting bracket is provided with an air bag, the air bag air compressor is provided with an automatic air charging device in a matching way, the automatic air charging device specifically comprises a controller, a pressure sensor arranged in the air bag, a liquid level sensor arranged at the upper part of a concrete frame column and electromagnetic valves arranged on each air bag air charging pipeline, the signal output ends of the pressure sensor and the liquid level sensor are respectively connected with the signal input end of the controller, and the signal output end of the controller is connected with a main switch of the air compressor and the control end of the electromagnetic valve on each air charging pipeline; the controller is internally provided with a wireless signal receiving and transmitting module and is in signal connection with the remote control device through the wireless signal receiving and transmitting module.
