Description
Technical field
The utility model belongs to rotary drilling rig servicing unit field, is specifically related to a kind of power head driving sleeve of rotary drilling rig.
Background technology
Rotary digging drill power head provides power for rig work, and be the core transmission component of rotary drilling rig work, it is made up of motor, reductor, bracket, headstock, actuating sleeve, damping device etc.Its operating principle is hydraulic motor output torque and rotating speed, increases and turns round, turned round realize bore operation with transmitting torque and rotating speed to drilling rod and drill bit by actuating sleeve through reductor and gear-box twice deceleration.Wherein actuating sleeve entirety is tubular structure, and inner ring has some uniform driving key bars (key bar quantity and layout are mated with selected drilling rod key bar), coordinates transmitting torque and pressure with drilling rod key bar.When rotary drilling rig drilling well, the moment of torsion that rotary digging drill power head exports realizes transmitting by actuating sleeve key bar and contacting of drilling rod key bar with rotating speed, drives drilling rod to rotate, thus drives drilling tool to rotate; Meanwhile, the plus-pressure that pressurization oil cylinder passes to unit head also passes to drilling rod by the contact of actuating sleeve key bar lower surface and machine lock drilling rod key bar pressurized plane, thus digs under driving drilling tool.In the driving contact of drilling rod and actuating sleeve, actuating sleeve is as consumable accessory, and hardness is less than drilling rod key bar.Therefore, the side that contacts with drilling rod key bar of actuating sleeve key bar and the lower surface serious wear that contacts with drilling rod key bar pressurized plane.During the heavy wear of key bar, gently then affect transmission efficiency, produce during work and impact, heavy then cause transmission failure.
At present, actuating sleeve generally has two kinds of structure typess, and one is key bar and body is monolithic, by forging process or integral casting forming; Another kind is combined type, and key bar is arranged on body inner ring by welding or bolt.Monoblock cast or when being connected by welding manner, though by continuing to use after fray built-up welding polishing after the wearing and tearing of key bar, built-up welding is wasted time and energy, and not easily reaches life size, re-uses the life-span also to shorten to some extent; And the existing actuating sleeve be bolted, have modified all-in-one-piece defect by removable key bar, but connecting bolt is by larger shearing force, easily causes connecting bolt to cut off and lost efficacy and then caused the accidents such as key bar comes off; Existing actuating sleeve body carries out cast molding with cast steel in addition, and processing problems faced is that allowance is large, and the casting quality of cast cannot ensure, heat treatment difficulty, the process-cycle is long, and scrappage is high, and production efficiency is low.
Utility model content
The purpose of this utility model is to provide a kind of power head driving sleeve of rotary drilling rig, solves the problems referred to above.
The utility model power head driving sleeve of rotary drilling rig, comprise actuating sleeve body and Duo Gen draw key bar, described actuating sleeve body offers many keyways vertically, many draw key bars are fixed in many keyways respectively by bolt, described actuating sleeve body is by large flange, upper flange, intermediate sleeve, lower flange is welded, upper flange and lower flange are welded on intermediate sleeve two ends, large flange is welded on the middle part of intermediate sleeve, the two ends of the keyway of described actuating sleeve body radially sink to forming deep gouge, one end through-thickness of described draw key bar convexes to form a pressure-bearing platform, the holding of draw key bar is in keyway and pressure-bearing decometer is put in deep gouge, pressure-bearing platform medial surface leans on the sidewall of deep gouge.
Described draw key bar with the mode holding of interference fits in the keyway of actuating sleeve body.
Described actuating sleeve body is upper and lower symmetrical structure.
Compared with prior art, the utility model has the advantage of:
Actuating sleeve revolution drive drilling rod time bear pressure but not bolt by actuating sleeve body and draw key bar interference fits face, when use machine lock drilling rod time this pressure-bearing platform by with actuating sleeve body contacts, pressure-bearing platform bears axial compression, avoids bolt directly to be sheared; Original actuating sleeve body casting structure is changed, adopts weldment structure, solve the problem that allowance is large, production efficiency is low, heat treatment is inconvenient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is schematic top plan view of the present utility model;
In figure: 1, actuating sleeve body, 2, large flange, 3, pressure-bearing platform, 4, lower flange, 5, intermediate sleeve, 6, draw key bar, 7, upper flange, 8, deep gouge, 9, keyway.
Detailed description of the invention
Contrast accompanying drawing below, detailed description of the invention of the present utility model is described in further detail.
Power head driving sleeve of rotary drilling rig as illustrated in fig. 1 and 2, comprise actuating sleeve body 1 and Duo Gen draw key bar 6, actuating sleeve body 1 offers many keyways 9 vertically, many draw key bars 6 are fixed in many keyways 9 respectively by bolt, actuating sleeve body 1 is by large flange 2, upper flange 7, intermediate sleeve 5, lower flange 4 is welded, upper flange 7 and lower flange 4 are welded on intermediate sleeve 5 two ends, large flange 2 is welded on the middle part of intermediate sleeve 5, the two ends of the keyway 9 of actuating sleeve body 1 radially sink to being formed deep gouge 8, one end through-thickness of draw key bar 6 convexes to form a pressure-bearing platform 3, draw key bar 6 holding in keyway 9 and pressure-bearing platform 3 holding in deep gouge 8, pressure-bearing platform 3 medial surface leans on the sidewall of deep gouge 8.
Draw key bar 6 with the mode holding of interference fits in the keyway 9 of actuating sleeve body 1.
Actuating sleeve body 1 is upper and lower symmetrical structure.
In sum, the revolution of the utility model actuating sleeve drives during drilling rod and bears pressure but not bolt by actuating sleeve body and draw key bar interference fits face, when use machine lock drilling rod time this pressure-bearing platform by with actuating sleeve body contacts, pressure-bearing platform bears axial compression, avoids bolt directly to be sheared; Original actuating sleeve body casting structure is changed, adopts weldment structure, solve the problem that allowance is large, production efficiency is low, heat treatment is inconvenient.
In description of the present utility model, term " interior ", " outward ", " longitudinal direction ", " transverse direction ", " on ", D score, " top ", the orientation of the instruction such as " end " or position relationship be based on orientation shown in the drawings or position relationship, it is only the utility model instead of require that the utility model with specific azimuth configuration and operation, therefore can not must be interpreted as restriction of the present utility model for convenience of description.
