The shackle device compact of the utility model embodiment, is adapted to be mounted on the car body of truck-mounted drilling rig, for example may be used
Referred to behind car body with being installed on behind upper vehicle working bench, it is relative with headstock, corresponding to the right side in Fig. 1, spirit easy to use
It is living, without dismounting.Screw-off mechanism is pushed out to operating position by the device by displacement cylinder 305 during work, thus realize button and/or
Shackle is operated.
Row explanation during below in conjunction with Fig. 1 to Fig. 9 to the course of work of the shackle device.
When performing shackle operation to drilling structure onto, screw-off mechanism is shifted the drilling structure of well head by shift mechanism 3 first
Place, then clamp the second of bottom by the second clamping part of clamper 2 and screw section, second rotation on top is clamped by unscrewing device 1
Section is twisted, then is turned round by the first mounting seat 102 of the stretching of shackle oil cylinder 101, contracting movement progress unscrewing device 1, the band of the first mounting seat 102
Dynamic first clamping part and first be held on the first clamping part screw center axis thereof of the section around drilling structure, you can real
The now shackle operation of drilling structure.When upper button or shackle is not required to, such as during truck-mounted drilling rig transfer place, the shifting of shift mechanism 3
Position cylinder 3 is retracted, and screw-off mechanism is moved to retrieving position, quickly can be moved to screw-off mechanism and not produced interference to drilling structure
Position, be additionally favorable for for truck-mounted drilling rig improve riding stability.The shackle device is installed on the car body of truck-mounted drilling rig
When, without dismounting, transition is convenient and time-saving laborsaving.
The insertion of I-shaped track 104 for being arranged at the bottom of the first mounting seat 102 of unscrewing device 1 is located at the installation of clamper 2
The rail for being equipped with spring 207 and ball 206 between the first arc chute body 204, the second arc chute body 205 on seat 203
On road loading plate, guiding and above-below direction when realizing that the first clamping part is rotated relative to the second clamping part it is spacing.Multiple bullets
The centre of sphere of spring 207 and ball 206 is located in the cambered way coordinated with I-shaped track 104, on the one hand can ensure that unscrewing device 1 is being unloaded
Ball 206 is set to hold unscrewing device 1 all the time because of spring 207 during button, to reduce two biass of the retaining part for screwing section
Power, reduces the risk that drilling structure is crushed；On the other hand, it is ensured that unscrewing device 1 has certain damping and reduction when setting back
The effect of noise.
The shackle device can also carry out upper button operation to drilling structure.When performing button operation to drilling structure, shackle
Oil cylinder 101 drive the first mounting seat 102 gyratory directions just with shackle when it is opposite.During upper button, unit head is rotated forward first, will be dynamic
The screw thread mouth of the upper tool joint of power head is fully screwed into the drilling rod of connection.When just starting to drill, because of the resistance suffered by drilling structure
Square is small, such as depends merely on and detained on unit head, then the screw thread crept between structure can not be locked, and when may cause drilling, drilling structure is not
Surely, normal drilling is influenceed.Need to carry out upper button to drilling structure further with shackle device for this, driller's hand can be according to behaviour
Make manometric pressure on platform to show, it is ensured that torque wrench moment reaches requirement.
During assembling shift mechanism 3, the second displacement cylinder mounting seat 304 is welded on mounting base 4.T-shaped slide rail 301 uses countersunk head
Screw is fixed on mounting base 4.During slide rail cell body 306 in second mounting seat 203 is pushed T-shaped slide rail 301, slide T-shaped
Rail 301 coordinates with the T-shaped chute of slide rail cell body 306.Then the limited block 302 at the two ends of T-shaped slide rail 301 or so is consolidated with bolt
It is fixed.The displacement left end of cylinder 305 is connected with the first displacement cylinder mounting seat 203-1 of the second mounting seat 203.Displacement cylinder 305
Right-hand member is connected with the second displacement cylinder mounting seat 304 with bearing pin.
When needing to perform shackle and/or the operation of upper button, displacement cylinder 305 stretches out, and cylinder barrel drives screw-off mechanism along T-shaped slide rail
301 move to operating position, creep into upper button or the shackle operation of structure.After the completion of operation or transfer job location
When, displacement cylinder 305 is retracted, and screw-off mechanism reaches retrieving position.In the case where rig is truck-mounted drilling rig, retrieving position can be made
Relative to operating position vehicle center of gravity reach, so as to improve the stability of driving cycle.
In the present embodiment, respectively clamp cylinder, displacement cylinder, shoring and be preferably oil cylinder.
From the above description, it can be seen that the utility model above example can realize at least one following technique effect：
Screw-off mechanism can be moved neatly between operating position and off-position, thus detained on convenient operation and/
Or shackle operation, after operation and/or shackle operation are detained in execution, it is also possible to screw-off mechanism easily is moved into avoidance drilling knot
The position of structure, accordingly, it is capable to improve the operating efficiency of button operation and/or shackle operation.
When shackle device is arranged at truck-mounted drilling rig, job location is reached, it is ready, it is necessary to during shackle, shackle device
Displacement cylinder stretches out, and screw-off mechanism moves to operating position, that is, move to well head drilling structure shackle position, simple and convenient, time saving
Laborsaving, high working efficiency can efficiently reduce the installation time of construction operation early stage, and reaching the spot just can be direct without installation
Use；Shackle device need not be dismantled in comfortable property, displacement cylinder is retracted, and drives screw-off mechanism to reach retrieving position, is set to
In retrieving position relative to operating position vehicle center of gravity reach, stability during traveling can be improved.
Shackle device compact conformation, everything by oil cylinder realize, can improve shackle and/or upper button operation it is automatic
Change degree.
The unscrewing device of shackle device is supported on clamper using floating support structure, it is ensured that can easily dismantle drilling knot
Structure.Under the cooperation of ball and spring, noise can also be reduced, there is preferable damping effect.
By I-shaped track and the fit system of cambered way between unscrewing device and clamper, both realize rotating guiding, and
So that shackle device compact conformation, small volume.
Finally it should be noted that：Above example is only used to illustrate the technical solution of the utility model rather than it is limited
System；Although being described in detail to the utility model with reference to preferred embodiment, those of ordinary skill in the art should
Understand：Specific embodiment of the present utility model can still be modified or some technical characteristics are equally replaced
Change；Without deviating from the spirit of technical solutions of the utility model, it all should cover in the claimed technical scheme of the utility model
In the middle of scope.
