Description
Technical field
The utility model relates to a kind of colliery crawler type all-hydraulic tunnel drilling rig combination hydraulic chuck assembly, belongs to coal mine drilling machineField.
Background technology
In prior art, coal mine gallery probing is mainly divided into two kinds by the form of conventional geologic drilling rod: cylindrical drilling rod 02 and Rhizoma SparganiiDrilling rod 01 (referring to Fig. 4-7). Chuck is an important component part of rig, and its function is to clamp drilling rod, turns to drilling rod transmissionSquare and axial force, drive drilling rod realize revolution and creep into. The applying working condition of chuck is more severe, must be able to bear maximum axially carryingLotus and maximum flywheel moment, and on-off action is frequent. The performance of chuck is directly connected to the reliability that rig uses, forDomestic macroporous footpath deep hole rig at present, output torque and the power of creeping into of rig are larger, and this just requires chuck be able to provideEnough large blessing power, ensures that drilling rod and slips do not produce relative sliding. And common combination hydraulic chuck slips used is full cardWatt, formed by 4 tile fragments, in the time that drilling rod used on ore deposit is Three-edged drill stem 01, owing to being 4 tile fragments, chuck is to Rhizoma SparganiiDrilling rod 01 accommodates effect bad, and chuck clamps the rear situation that occurs that unbalance stress causes gum cover to damage of Three-edged drill stem 01, veryTo there will be the phenomenon can't clip.
Utility model content
The utility model technical issues that need to address are to provide a kind of combination hydraulic chuck assembly, can make rig use notDuring with drilling rod, need not change chuck, make rig versatility stronger, and make rig whole compact conformation, at utmost improve down-hole workPeople's operating efficiency.
For addressing the above problem, technical solution adopted in the utility model is:
Crawler type all-hydraulic tunnel drilling rig combination hydraulic chuck assembly for a kind of colliery, comprises rotating mechanism assembly, combined liquidPress chuck assembly, pallet assembly, rail assembly, it is front lower that wherein said combination hydraulic chuck assembly is arranged on rotating mechanism assemblySide, pallet assembly front upper place, rail assembly is positioned at pallet assembly bottom, described combination hydraulic chuck assembly comprise drive end bearing bracket,Shell, support ring, gum cover, cone circle, channeled disks, slips, slips spring, bonnet, bearing pin, described slips is placed on channeled disksIn, channeled disks is connected by bearing pin with drive end bearing bracket, bonnet, and bearing pin is also connected transmitting torque with the main shaft in rotating mechanism assembly,Support ring, gum cover successively coaxial sleeve in slips outside.
Further, described slips is made up of 3 tile fragments with fin.
Further, described slips medial surface arranges axial V groove and annular groove radially, and described annular groove cross section is V-arrangement.
The beneficial effect that adopts technique scheme to produce is:
The utility model assembled hydraulic chuck assembly adopts 3 tile fragments, can use cylindrical drilling rod and Three-edged drill stem and not simultaneouslyNeed to change chuck, and Three-edged drill stem be accommodated effective, there will not be the situation of drilling rod and slips relative sliding, reduce brillThe wearing and tearing of bar and slips, and make rig versatility stronger, at utmost improve underground labour's operating efficiency.

Detailed description of the invention
Below in conjunction with accompanying drawing, utility model is described in further detail:
The utility model relates to a kind of colliery crawler type all-hydraulic tunnel drilling rig combination hydraulic assembly, adopts 3 tile fragment structuresSlips realize the good clamping effect to Three-edged drill stem.
As shown in Figures 1 to 3, the utility model comprise rotating mechanism assembly 1, combination hydraulic chuck assembly 2, pallet assembly 3,Rail assembly 4, wherein said combination hydraulic chuck assembly 2 is arranged on rotating mechanism assembly 1 front lower place, before pallet assembly 3Top, rail assembly 4 is positioned at pallet assembly 3 bottoms, described combination hydraulic chuck assembly 2 comprise drive end bearing bracket 21, shell 22,Support ring 23, gum cover 24, cone circle 25, channeled disks 26, slips 27, slips spring 28, bonnet 29, bearing pin 210, described inSlips 27 is placed in channeled disks 26, and channeled disks 26 is connected by bearing pin 210 with drive end bearing bracket 21, bonnet 29, and bearing pin 210 alsoBe connected transmitting torque with the main shaft 11 in rotating mechanism assembly 1, support ring 23, gum cover 24 successively coaxial sleeve outside slips 27Side.
In order to ensure that 3 tile fragments move simultaneously, described tile fragment is with fin 270.
In order to ensure to clamp effect, described slips 27 medial surfaces arrange axial V groove and annular groove radially, and described annular groove cross section is VShape, when holding drill pipe, drilling rod is difficult for sliding.
The utility model assembled hydraulic chuck assembly slips adopts 3 tile fragments, utilizes between every tile fragment and Three-edged drill stem per pass ribLocking principle, both can solve the oild chuck clamping Three-edged drill stem unbalance stress problem being made up of 4 tile fragments, also can be fineThe oild chuck that formed by 4 tile fragments of solution in the time of clamping Three-edged drill stem, there is the problem of skidding, can use cylindrical simultaneouslyDrilling rod and Three-edged drill stem and do not need to change chuck---referring to Fig. 4～Fig. 7, and the utility model combination hydraulic chuck is usedSlips on original slips basis, increase tab configurations, like this chuck open or when locking griffith woodsorrel herb piece move simultaneously, centeringProperty obviously promotes, and makes rig stressed steady in the time of running work, and the propulsive thrust that can make rig produce in the process of drilling is unlikely toDrilling rod and slips are slided, make drilling rod and slips reduce wearing and tearing, and make rig versatility stronger, operating efficiency improves,Large degree has improved underground labour's operating efficiency.
