Abstract
The utility model discloses a buffering transmission device of a coal bed gas drilling machine. The buffering transmission device of the coal bed gas drilling machine is formed by a central tube, a seal pressing sleeve, a spring and a shell body, the other end portion of the central tube and the other end portion of the seal pressing sleeve are of a threaded structure, one end of the shell body is connected with a flange on the central pipe, the other end of the shell body is mounted at the lower end of a boss of the seal pressing sleeve through a pressing cover in a sleeved mode, an involute inner spline is designed on the lower portion of the inner wall of the shell body, an involute outer spline is arranged on the outer circle of the boss of the seal pressing sleeve, and the involute spline structure transmits power. A shaft sealing structure is arranged on the matching portion of the central tube and the seal pressing sleeve, one end, mounted on the seal pressing sleeve in the sleeved mode, of the spring is in contact with a flange plate of the central tube, and the other end of the spring presses the shaft sealing structure tightly. Due to the fact that damage on a power swivel by well drilling vibration of the coal bed gas drilling machine is retarded, the service life of the power swivel is prolonged, and a protection function is performed to the whole drilling machine, and the buffering transmission device of the coal bed gas drilling machine conveys slurry and transmits power needed by a drilling pipe in well drilling operation.
Description
Technical field
This applicable novel coal bed gas drilling machine drilling technology field, specifically buffer transmission of a kind of coal bed gas drilling machine of relating to.
Background technology
Snubber is one of important matching component in coal bed gas drilling machine, and its effect is mainly be used to slowing down coal bed gas drilling machine drilling well vibrations, power swivel to be destroyed, and extends the application life of power swivel and whole rig is played a protective role.If there is no this cover buffer, coal bed gas drilling machine is when drillng operation, and the drilling well vibrations destroy very large to power swivel, approximately makes a call to two mouthfuls of wells and just needs to change power swivel, seriously shorten the application life of power swivel, the service efficiency of the whole rig of impact.
The utility model content
The purpose of this utility model is to provide a kind of buffer transmission of coal bed gas drilling machine.Be used for slowing down coal bed gas drilling machine drilling well vibrations power swivel is destroyed, extend the application life of power swivel and whole rig is played a protective role, in drillng operation, slurry conveyed, transmit the needed power of drilling rod.
the technical solution adopted in the utility model is: a kind of coal bed gas drilling machine buffer transmission, it is characterized in that: by central tube, sealed pressing sleeve with the central tube suit, the housing that is sleeved on the spring on sealed pressing sleeve and is fixed on central tube forms, the other end of described central tube and sealed pressing sleeve is the oil tool joint thread structure, described housing is barrel-shaped structure, one end is connected with the flange on central tube, the other end is sleeved on the boss lower end of sealed pressing sleeve by gland, the bottom of inner walls is designed with internal spline, the boss cylindrical of sealed pressing sleeve is provided with external splines, internal spline and external splines coordinate transferring power, sealed pressing sleeve can slide up and down under the guiding of spline structure, be provided with axle sealing structure at central tube and sealed pressing sleeve matching part, described spring one end that is sleeved on sealed pressing sleeve contacts with the flange of central tube, other end compression axis hermetically-sealed construction.
Be provided with the guidance tape that play the guiding role between described central tube and sealed pressing sleeve.
Described axle sealing structure consists of packing box and the lower grommet, the mud packing that are positioned at packing box.
Also be provided with the spacer ring that separates for the mud packing in described packing box.
Mounting O-shaped rings between described gland and sealed pressing sleeve.
Described internal spline and external splines are involute spline.
Operating principle and use procedure: in coal bed gas drilling machine, the coal bed gas drilling machine buffer transmission is arranged between power swivel and drilling rod.When the coal bed gas drilling machine drillng operation, pressure that drilling rod runs into is delivered on the sealed pressing sleeve of buffer transmission with vibrations, forces sealed pressing sleeve to be subject to power upwards, and sealed pressing sleeve passes to spring with power, and the spring stress compression, play cushioning effect.
This structure adopts high-strength spring, and whole equipment is played cushioning effect; The central tube place adopts packing_seal, and the mud of inside is played sealing function; Adopt the involute spline slide mechanism, can make buffer transfer drilling rod moment of torsion, can guarantee buffer stroke again.
Description of drawings
Fig. 1 is this applicable novel structural representation.
The specific embodiment
