Document Type and Number:
WIPO Patent Application WO/2018/072228
Kind Code:
A1
Abstract:
An overwinding buffer device and method for a vertical hoisting system. The vertical hoisting system comprises a derrick (1) and a hoisting container (5). A hydraulic buffer device is disposed on the derrick (1), the hydraulic buffer device comprising at least one buffering hydraulic cylinder (14, 14-1, 14-2, 14-3, 14-4, 14-5) and buffering pressure rollers (7) disposed corresponding to the buffering hydraulic cylinders (14, 14-1, 14-2, 14-3, 14-4, 14-5); the buffering hydraulic cylinders (14, 14-1, 14-2, 14-3, 14-4, 14-5) are disposed on the derrick (1); piston rods of the buffering hydraulic cylinders (14, 14-1, 14-2, 14-3, 14-4, 14-5) are disposed horizontally and outer ends of the piston rods face towards the hoisting container (5); the buffering pressure rollers (7) are horizontally fixed on an outer side wall of the hoisting container (5) and arced surfaces of the buffering pressure rollers (7) face towards the piston rods of the buffering hydraulic cylinders (14, 14-1, 14-2, 14-3, 14-4, 14-5). The overwinding buffer device and method for a vertical hoisting system are safe and reliable, can achieve rapid restoration, are simple in structure and have low cost.
