Description
Technical field
The utility model relates to the mechanized equipment field, relates in particular to a kind of ability and realizes automatically reset clamper.
Background technology
Clamper is the main executing agency of all-hydraulic drill, is positioned at the front end of rig, is mainly used in the boring procedure, dismantles or install additional drilling rod, prevents drilling rod and drilling tool landing.At present, clamper mainly is made up of critical pieces such as base, oil cylinder, two claws.Wherein, two oil cylinders are left and right symmetric arrangement on base, and oil cylinder is connected with claw, forms the through hole that drilling rod can pass through between two claws.When installing drilling rod additional, at first control clamper two oil cylinder move toward one another, claw is clamped last drilling rod, then with the oild chuck of unit head will be to be installed additional the drilling rod clamping; The control unit head is rotated in the forward, and drilling rod to be installed additional is connected with a last drilling rod, and controlling clamper then, to grasp the drilling rod of front motionless; Unit head reverse rotation then is because the oild chuck of unit head grasps the back drilling rod, so drive back drilling rod reverse rotation; Make forward and backward two drilling rod generation relative motions; Then unclamp being threaded between two drilling rods, and shrink back, two drilling rods are separated, unclamp the oild chuck of unit head at last; Drilling rod is disassembled, accomplish unloading process.But because clamper adopts two cylinder structures, complex structure, cost is high and can not automatic aligning.
The utility model content
To the above-mentioned defective of prior art, the utility model provides a kind of clamper that automatically resets that uses an oil cylinder just can accomplish automatic location and aligning.
The utility model provides a kind of clamper that automatically resets to comprise: base, casing, oil cylinder, two fixture blocks, positive stop, spring; Said casing and oil cylinder are fixed together; The piston rod of said oil cylinder is fixedly connected with a fixture block screw thread, on another fixture block static housing; Said postive stop baffle is fixed on the base; Said spring one end is fixed on the journal stirrup of base, and the other end is fixed on the casing.
Optional, the said clamper that automatically resets comprises two anchor clamps.
Optional, between two anchor clamps, be provided with watch window, the situation of seam when being convenient to observe the connection of two drilling rods.
Optional, at the said clamper that automatically resets the drilling rod carriage is installed at the back, installing or playing during dismounting drilling rod guiding and protective effect additional.
Optional, two springs are all arranged on each anchor clamps.
When clamping cylinder, the elongation of the piston rod of oil cylinder promotes to travel forward with its fixing fixture block simultaneously; When piston rod is run into the positive stop that is fixed on the frame, the piston rod stop motion, fixture block and the drilling rod body of rod cylindrical that be fixedly connected with it this moment are tangent just.Oil cylinder works on; This moment, the oil cylinder piston bar was slack, and cylinder body moves backward and drives the casing that is fixed together with cylinder block simultaneously and move backward, and another fixture block and casing are fixed; Also, so just accomplished the action of automatic aligning along with motion backward clamps drilling rod.
When oil cylinder unclamped, piston rod back shrank, and realized automatically reseting through gravity and spring force.
Be provided with before two anchor clamps of the utility model and install additional or the watch window during dismounting drilling rod, the situation of seam when being convenient to the operator and observing two drilling rods and connect.
The utility model is equipped with the drilling rod bracket system at the back, and effect is that drilling rod can roll on carriage, and the protection drilling rod is avoided wearing and tearing, the handled easily person uses simultaneously.
In sum, when the technical scheme of using the utility model embodiment can realize rig down or install drilling rod additional the automatic aligning of clamper with automatically reset, principle is simple, ingenious, save cost, easy to use, have a wide practical value.
Description of drawings
