Development and Application of Hydraulic Calipers Disc Brake Winch

Abstract:

The master winch of traditional spindle mechanical drilling machine has both the advantages of hook free-falling and rapid drilling tools lowering and the disadvantages of low abrasion resisting of belt asbestos braking, low friction coefficients, difficult operation, low sensitivity, poor heat dissipation, poor high temperature property and difficult safety control for drilling tools assembling and disassembling. For the master winch of full-hydraulic dynamic head drill, the elevating speed is controlled by the flow of hydraulic system, the safety of drilling tools assembling and disassembling is easily guaranteed, and the cooling forced by hydraulic system is also good. A hydraulic winch of full-hydraulic core drill is developed; the above problems of the master winch of traditional spindle mechanical drilling machine are solved by hydraulic pressure.
