Detailed description of the invention
Below in conjunction with accompanying drawing, to this utility model, above-mentioned and other technical characteristic and advantage are described in more detail.
Refer to shown in Fig. 1～3, the automatic turning mechanism of a kind of drill power head of this utility model embodiment, it includes derrick 1, chain 2, unit head 3, enhancing ring 4, changes the unit head support arm 5 of 4 upsets, upset support arm, roller bush 7, roller 8, bearing, bearing pin 10 and drilling rod 11 around lifting.
Wherein, described derrick 1 is formed the shelf structure that spreads out, derrick 1 symmetrical suspension chain 2 by channel-section steel and square tube welding；Chain 2 traction enhancement ring 4 and unit head 3, and then traction motivation package head automatic turning mechanism.
Described unit head 3 both sides are provided with unit head support arm 5, and unit head support arm 5 through enhancing ring 4 and is connected with unit head 3；Unit head support arm 5 is socketed with roller bush 7 with the connection end of derrick 1, and the periphery of roller bush 7 is supported by roller 8.
Unit head support arm 5 can rotate around the axis of enhancing ring 4.
The side of unit head support arm 5 is installed with upset support arm, and the two passes through holding screw or weld connection；Upset support arm includes overturning axle sleeve 61 and upset support arm plate 62, and both use weld connection.
The side of derrick 1 is equipped with bearing, and both can use welding or bolt-connection；It is installed with on bearing and overturns the bearing pin 10 that support arm plate 62 contacts.
Described bearing includes the base-plate 91 that be connected fixing with derrick 1 and the support lug 92 being connected with bearing pin 10.
Referring to shown in Fig. 4, the upset support arm plate 62 of the present embodiment includes inner concave A and the arcuate surface B relative with inner concave, and in unit head motor process, inner concave contacts with bearing pin 10 respectively with arcuate surface, changes the kinestate of unit head.
When stacks, unit head 3 under angle of crater state slides into lower section, when the A face overturning support arm plate 62 touches bearing pin 10 outer arc, bearing pin 10 hinder unit head 3 continue move down, unit head 3 and unit head support arm 5 and then overturn around enhancing ring 4 and fix at lower limit, now tilt drilling rod by manpower or winch, dock unit head 3 after righting, realize fast quick change bar, convenient and strength-saving.
When normally creeping into, owing in well, the correcting effect of drill string 11, unit head 3 and unit head support arm 4 keep vertical sliding mode, do not overturn.
Need unit head 3 with well head drill string 11 timing when unloading drilling rod, only needing manpower to move gently makes unit head 3 utilize the B face of upset support arm plate 62 to touch bearing pin 10 inner arc during gliding, the lower contact of unit head 3 is directed to vertical direction, after docking with drill string in well 11, upward sliding mentions the height of a drilling rod, clamp system clamping bottom drill string, unit head 3 inverts to be dismantled completely by first drilling rod, then will put outside drilling rod lower end by manpower, decline unit head 3, when the A face overturning support arm plate 62 touches bearing pin 10 outer arc, bearing pin 10 hinder unit head 3 continue move down, unit head 3 and unit head support arm 5 and then overturn around enhancing ring 4 and fix at lower limit, by drill rod fastener dismount set, easily this drilling rod is dismantled from unit head 3 by labour-saving.
The foregoing is only preferred embodiment of the present utility model, be merely illustrative for utility model, and nonrestrictive.Those skilled in the art understands, it can be carried out many changes, amendment, even equivalence, but fall within protection domain of the present utility model in utility model right requires the spirit and scope limited.
