Description
Technical field
The utility model relates to a kind of oil field instrument, specifically, relates to a kind of guiding mounting or dismounting structure of mandrel and protection tube of inserting tube.
Background technology
Inserting tube is a very important system component in field of oil drilling; When the protection tube the inside of inserting tube that the mandrel of inserting tube is packed into; Because mandrel is elongated; Gap between mandrel and the protection tube is very little, and the damping cushion rubber is again an interference fit with the protection tube, so unusual difficulty when mandrel installed toward protection tube the inside.
When mandrel is assembled toward protection tube the inside, because mandrel is oversize,, be easy to generate collision or extruding if there is not frock tool to guarantee assembling, and with indivedual machine components or electronic component damage.And in assembling process, when being assembled to the middle part, stuck phenomenon appears easily.Therefore need a kind of technology that when assembling, can mandrel pulled out or advance smoothly of utility model from the protection tube.
The utility model content
To the technical problem that exists in the prior art, the purpose of the utility model is: provide a kind of simple in structure, easy to operate, assembling is smooth, not the guiding mounting or dismounting structure of the mandrel of the inserting tube of fragile parts and protection tube.
In order to achieve the above object, the utility model adopts following technical scheme:
The guiding mounting or dismounting structure of the mandrel of inserting tube and protection tube comprises: place the mandrel supporting mechanism of mandrel, the tight mechanism of protection collet chuck and the axial moving mechanism of fixing protection tube; Axial moving mechanism comprises sleeve body and leading axle, and sleeve body is static relatively with the protection tube, and leading axle is through translation mechanism axially translation in sleeve body; Mandrel supporting mechanism, the protection tight mechanism of collet chuck and sleeve body set gradually, and the axis of mandrel, protection tube and leading axle is located along the same line; What leading axle was detachable is connected on the mandrel.
After adopting this structure, through leading axle axially translation in sleeve body, leading axle is along axial pulling or promote mandrel, makes mandrel get into or leave the protection tube stably along axis.Simple in structure, easy to operate.Simultaneously elongated mandrel carries out support by the mandrel supporting mechanism, avoids mandrel to fracture or impaired.The axis of mandrel, protection tube and leading axle keeps point-blank, avoids the collision or the extruding of mandrel and protection tube, prevents that parts are impaired, guarantees that mandrel drawn in or release the protection tube smoothly.
Translation mechanism is a pinion and rack; Tooth bar is positioned on the leading axle, and what gear was turnable is installed on the sleeve body.Adopt pinion and rack, simple in structure, easy to operate, only need the rotation of adjusting gear, the engaged transmission through gear and tooth bar effectively becomes translation with rotation, and stable drive is easy to adjust.
Translation mechanism also comprises: gear shaft, two side fixed heads and a back fixed head; Gear is installed on the gear shaft, and the two ends of gear shaft are installed on two side fixed heads; Two side fixed heads are fixed on the fixed head of back, and the back fixed head is fixed on the outer wall of sleeve body; Sleeve body is provided with opening, and gear passes this opening and extends in the sleeve body and the tooth bar engagement.After adopting this structure, simple in structure, easy to operate.When the gear shaft of an end wherein passes the side fixed head, this end is that outer six sides pull mouth, cooperates with spanner, rotation that can adjusting gear.
Be connected to the transition connecting axle between mandrel and the leading axle; The thread spindle of mandrel and transition connecting axle spin through screw thread, and transition connecting axle and leading axle spin through screw thread.After adopting this structure, promptly introduce the transition connecting axle, avoid with elongated mandrel and long leading axle directly is connected cause operate inconvenient.Simultaneously, the length of transition connecting axle is shorter, can be equipped with corresponding transition connecting axle to the thread spindle of the mandrel of different size, changes different transition connecting axles, and a set of equipment is promptly applicable to the mounting or dismounting of the mandrel of multiple structure or size.
