Abstract

The invention relates to oil development equipment, in particular to a pulley drive balance type lifting system for a drilling machine in the mechanical field of drilling machines. According to the pulley drive balance type lifting system for the drilling machine, hook load is balanced by a balancing box so as to reduce the maximum driving force based on a pulley drive principle. The pulley drive balance type lifting system for the drilling machine has the advantages that 1) energy is saved, and the maximum power can be reduced; the maximum drive power can be reduced effectively by a balance mode according to a movable pulley drive principle; theoretically, under the conditions of the same hook load and the same lifting speed, compared with the conventional drilling machine, the pulley drive balance type lifting system has the advantages that the maximum power can be reduced by 50 percent, and the system has obvious effects of clipping peaks and saving energy; 2) the labor intensity of operation staff can be reduced; and the balancing box has the function of an elevator type load box, so that operation staff can be lifted on a derrick of the drilling machine conveniently, and objects such as tools can be conveyed conveniently.

Description

technical field

[0001] The invention relates to a pulley drive balanced drilling rig hoisting system in the field of drilling machinery. Background technique

[0002] Drilling rigs are important equipment for geological exploration, underground well drilling, oil and gas exploration, etc. It mainly includes ground rotary drilling equipment, well fluid circulation system equipment, lifting system equipment, power drive equipment, transmission system equipment, control systems and testing Display instruments, rig base and auxiliary equipment, etc. So far, the lifting system equipment of the drilling rig is still a swimming system composed of a winch driven crown block, traveling block, and wire rope, and the drill pipe is driven up and down by hooks, faucets, etc. Although the energy-saving effect and operational performance have been greatly improved through continuous technical improvement, the basic principles of oil drilling rigs have not changed fundamentally, and the fu...
