The invention discloses an automatic cooling device for a disc brake of a petroleum drilling rig winch. The automatic cooling device is characterized in that a cooling water pump, a water pump motor and a functional water tank are installed on a pry base; a radiator fan and a fan motor are installed above the functional water tank; an auxiliary water tank is installed above the radiator fan, an external water filling nozzle is formed in the top end of the auxiliary water tank, and the bottom end of the auxiliary water tank is communicated with the functional water tank through an S-shaped radiating tube; a water inlet of the cooling water pump stretches into the functional water tank, a water outlet of the cooling water pump is communicated with a cooling passageway of a winch brake disc through a water outflow passageway, and the bottom of the cooling passageway of the winch brake disc is connected back to the auxiliary water tank through a water return pipeline; and all sensors are connected with a controller; and the output end of the controller is connected with the water pump motor, the fan motor and an alarming device. The automatic cooling device is compact in structure, high in integration level, stable in automatic control performance, high in intelligent degree and excellent in cooling effect and can be wholly moved along with the drilling rig winch.
Description
technical field [0001] The invention belongs to the technical field of mechanical equipment, and relates to an automatic cooling device for disc brakes of an oil drilling rig winch. Background technique [0002] Oil drilling rig drawworks hydraulic disc brake cooling device is an important part of the AC variable frequency drilling rig. It mainly provides cooling medium for the winch disc brake to prevent the brake performance from being affected by the high temperature of the disc brake shoe, and to ensure the normal operation of the main brake device of the winch, resulting in Major safety accidents such as slip drilling and sudden drilling. [0003] The existing winch disc brake forced cooling device belongs to an open circulation system, which requires frequent manual operation of the start and stop of the cooling device, which cannot realize the automatic cooling winch disc brake function, poor monitorability, and easy to cause the temperature of the disc brake shoe to ...
