Abstract
The utility model relates to a one-cylinder pneumatic tooth inserting clutch used on a driller for controlling a winch. When the utility model is not lifted up, contact and abrasion between a movable and a static jaws are avoided. A ring shoulder sheathed with a spring 14 is arranged on the movable jaw of the transmission shaft of a gearbox. The end of the transmission shaft (22) is fixed with a connecting plate 12, and the connecting plate is provided with a cylinder sleeve. A piston rod is extended out of a cylinder, an axial air hole passage 20 communicated with a cylinder chamber 21 is arranged in the piston rod, and the end shaft of the piston rod is provided with an air guiding faucet 1. A pull plate 3 is sheathed with the piston rod transversely, and the pull plate and the upper and the lower ends of the pull plate are provided with hinge shafts (4, 18) wound with pull ropes tying to the movable jaw. When the cylinder is filled with air, the movable jaw is pulled by the pull plate on the top part of the piston rod via the pull rope to separate from the static jaw, and the movable jaw is combined with the static jaw when the air stops filling.
Description
The utility model relates to a kind of jaw clutch of well-digging rig control winch, belongs to the pneumatic jaw clutch of single cylinder.
The well-digging rig as oil field and geological drilling rig, has on the operating table and rotates and elevator system.In the elevator system by drilling tool in the winch winding shaft, it with the power output speed changing box transmission shaft on jaw clutch clutch realization winch work or stop.Present clutch on the transmission shaft of gearbox is to stir shifting block or ring makes the static interlocking teeth clutch by shift fork, and the dynamic/ static tooth embedding is the rigidity combination.When winch did not promote, the dynamic/ static tooth embedding should be in separation; When on the rig during another rotation system rotary drilling, above-mentioned dynamic and static two tooth embeddings are also being followed rotation, and two tooth embeddings will come in contact and rub in following rotary course, cause invalid wearing and tearing.Because the rotary drilling time more than the lifting time, is followed the rotation wearing and tearing in such two teeth are embedded in for a long time.Thereby serious wear, need to repair and upgrade, cause the waste on the manpower and financial resources.
The purpose of this utility model is to avoid above-mentioned deficiency of the prior art, can avoid the interlocking of two teeth to touch the pneumatic jaw clutch of single cylinder of control winch on the rig of wearing and tearing, the life cycle that can prolong clutch under not promoting and provide a kind of.
The purpose of this utility model can reach by the following technical programs: on the jack shaft of control boring winch, axle head is equipped with the dynamic/ static tooth embedding.Be with spring 14 by ring shoulder on the dynamic interlocking teeth, transmission axle head crosswise fixed yoke plate 12 is made the cylinder sleeve 10 that the projection threaded body is connected with the end at the middle part of yoke plate, and piston rod stretches out outside the cylinder, has duct, axle center 20 to be communicated with cylinder chamber 21 in the body of rod, and rod end connects air guide cock tap.Tailpiece of the piston rod is with arm-tie 3, and it and yoke plate both sides are equipped with hinge (18,4) and are tethered on the dynamic interlocking teeth around wire rope 13.
Can between cylinder sleeve and piston, arm-tie and air guide cock tap and yoke plate and transmission axle head, seal ring, pad be housed; Cavity is arranged at the end of yoke plate and cylinder sleeve, center hole and cavity are arranged on the yoke plate, the center transmission shaft oil hole is communicated with, and center hole is communicated with external oil nozzle 19 with oil pipe.
The utility model can have following effect than above-mentioned prior art: because the transmission axle head is equipped with the cylinder control system, when the rotary system of rig is worked, ventilation ejects piston rod to drive the both sides stay cord dynamic interlocking teeth is separated with static interlocking teeth, produce contact and wearing and tearing, the life time of favourable prolongation tooth embedding between the dynamic/ static tooth embedding of its solenoidoperated cluthes thereby avoided winch not work down.
Fig. 1 is the utility model complete section diagrammatic sketch.
Fig. 2 is that upward A---A is to view on the figure.
Below in conjunction with accompanying drawing will the utility model is described in further detail.
By shown in Figure 1, transmission shaft 22 ends of gearbox are equipped with the work that winch on the rig is controlled in dynamic/ static tooth embedding (16,23).The utility model is to make shoulder 25 and sleeve spring 14 on dynamic interlocking teeth 16 bodies.Use fixedly yoke plate 12 of bolt (8,9) on transmission shaft 22 terminations, make spring 14 pressurizeds, the upper and lower end of yoke plate can be made the two-seater ear and be installed with hinge (17,18).The middle part of yoke plate has the protruding circular column threaded body to be connected with the cylinder sleeve 10 at the end, and the piston rod 6 in the cylinder sleeve passes cylinder cap 7 and stretches out outside the cylinder; There is pore road, axle center 20 to be communicated with in the piston body of rod with cylinder chamber 21; Tailpiece of the piston rod is equipped with air guide cock tap 1, is communicated with source of the gas by Pneumatic valve.Be with horizontal arm-tie 3 on tailpiece of the piston rod, the upper and lower end of arm-tie also is equipped with the hinge (4,5) relative with hinge (17,18), shows as Fig. 2; Be wound with steel wire tow line 13 on two hinges, the stay cord end is fastened being screwed into dynamic interlocking teeth and is formed on the coupler body 15 of bad shoulder 25.
For guaranteeing the sealing of sealing part, seal ring, pad (26,2,11) can be housed between cylinder sleeve 10 and piston 6, arm-tie 3 and air guide cock tap 1 and yoke plate 12 and transmission shaft 22.Because of center oil hole 24 is arranged on the transmission shaft, leave cavity 27 between yoke plate 12 and the cylinder bottom, the center nose end is drawn with external oil nozzle 19 with oil pipe and is communicated with on the transmission shaft.Above-mentioned air guide cock tap is for purchasing part.
When boring winch is not worked, and rotary system makes the cylinder gas injection in work, and piston rod pushes arm-tie 3 and draws dynamic interlocking teeth 16 to separate with static interlocking teeth 23 by wire rope 13, comes in contact between avoiding two teeth to be embedded in following in the rotary course and weares and teares.During winch work, bleed off gas in the cylinder, spring 14 will reset by compression, and elongation pushes away dynamic interlocking teeth and static interlocking teeth meshes, and can give winch transmission of power by transmission shaft.
