A new type of drilling rig

Abstract

The present invention is a novel drilling rig, comprising a base; a driving device fixedly connected above the base, on which an output shaft of the driving device is arranged; a gearbox, on which an input shaft of a gearbox is arranged, and the input shaft of the gearbox and The output shafts of the driving device are connected; the transfer case is connected to the output end of the gearbox, and it has several output ports; the hoist is connected to an output port of the transfer case, and a rotating shaft is installed inside; the brake mechanism, connected to the end of the shaft of the winch; the gyrator, connected to the other output port of the transfer case; the upper chuck, installed above the gyrator; the drill rod, connected to the upper chuck The lower chuck is connected to the bottom of the drill pipe; the driving device is a frequency conversion motor, and the frequency conversion motor is connected to a frequency converter through a circuit; the purpose of the present invention is to solve the problem of high energy consumption of current drilling rigs, which cannot realize stepless speed change , and problems such as fragile.

Description

technical field [0001] The invention belongs to the field of drilling equipment, and in particular relates to a novel drilling machine. Background technique [0002] Drilling rig is a common drilling equipment in industry. It has been widely used in prospecting, railways, highways, bridges, water conservancy and hydropower, tunnels, wells, anchor rods, small-diameter diamond core rope core drilling, industrial and civil construction, and engineering geological exploration. , geothermal drilling, coalbed methane drilling, outburst prevention drilling rigs and other drilling. [0003] The motors equipped with traditional drilling rigs are generally ordinary motors, and the mode of elastic pin coupling and wet friction clutch connection is generally used between the gearbox and the motor. This mode generally has the following shortcomings: First, the energy consumption is high. During the drilling cycle, most of the time the actual load of the drilling rig is only about half o...
