Abstract
The invention relates to a fastening project drill pipe connection method and device. The method includes the following steps that a steel pipe drill pipe penetrates and is inserted into an upper connector and a lower connector; the upper connector is embedded into the lower connector, a drill pipe connecting cap is connected with the lower connector in a rotation and sealing mode through a clamping groove and locked through a top device, and connection positions between the steel pipe drill pipe and the upper connector and between the steel pipe drill pipe and the lower connector are welded and sealed. Due to the fact that hexagonal rotation is adopted, the drill pipe adopts a double-end square-tooth reversed screw thread fastening connection construction process, the defects in products produced through the three methods in the existing markets are overcome, a plurality of primary technical indexes such as sealing performance, perpendicularity and abrasion resistance meet the designing requirements, and a problem in rotation drilling rig construction is solved.
Description
Technical field
The present invention relates to a kind of engineering the drilling construction drilling rod coupling arrangement, be specially adapted to the drilling rod method of attachment of fastening type engineering and the device of the aspects such as bridge pier, harbour, road, subway well head, super highrise building pile foundation construction and urban construction.
Background technology
Engineering rotary rig drilling rod connecting mode that at present China produces is more general following three kinds of modes: 1, flange connect mode, in construction, deposit that labor intensive is large, work efficiency is low, bolt consumption is large, and cost of labor expense is high, meet bad ground drilling construction, bolt is easily cut off.2, six side's clip type movable connecting modes, exist in construction that gap is large, sealing, up rightness, the defect such as wear no resistance, and are prone to the inclined to one side hole of inclined hole, and scarfing cinder difficulty at the bottom of hole, affects pile quality, and application life is short.3, screw thread connecting mode, in construction, existing can only be clockwise, can not reverse, and meets silt and infiltrates inconvenient, antitorque, the anti-rock stratum of upper and lower drilling rod poor performance, affects construction speed.
The above three kinds of connecting mode, once repeatedly implemented solution, but eventually because labour intensity is large, energy and material consumption, the cost such as artificial is difficult to reduce, quality safety index is difficult to control, just bored pile foundation detection of construction quality standard is high at present, require, under rigorous condition, to can not meet the requirement of present construction technology quality specifications.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of Novel engineering drilling rod tight joint method and apparatus.
For solving the problems of the technologies described above, the present invention realizes as follows: a kind of fastening engineering drilling rod coupling method and device, comprise the following steps: steel pipe drilling rod is penetrated and is inserted in top connection and lower contact;
After described top connection cover is embedded in described lower contact, and drilling rod connected to cap by draw-in groove, rotate airtight connection with described lower contact, top arrangement is locked;
Welded seal is carried out in junction in described steel pipe drilling rod and described top connection, described lower contact.
Good effect of the present invention is: because the present invention has adopted six side's jar rods, adopt the design technology form of construction work of the anti-silk of double end side's teeth tight joint, in service in construction,, sealing stable through practice assessment drilling rod repeatedly, Vertical performance are good; Antitorque, anti-performances of rock is strong, and work efficiency improves; Pore-forming is by detection, and hole wall is balanced, at the bottom of hole without sediment, without inclined hole, the defect such as hole partially, successful, reach and improve hole quality technical indicator, having solved at present the product Shortcomings of three kinds of drilling rod connecting modes in sum, and a great problem that exists in construction of rotary rig.
Accompanying drawing explanation
Fig. 1 is that top connection of the present invention connects with drilling rod the structural representation that cap is connected;
Fig. 2 is lower contact of the present invention and the structural representation being connected of steel pipe drilling rod
Fig. 3 is the structural representation that drilling rod of the present invention connects cap
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
As shown in the figure, the CGH fastening type engineering lever coupling head that one embodiment of the invention provides, comprises that top connection 1, lower contact 2 and drilling rod connect cap 3.
Top connection 1 is circular ring structure, at 2/3 place of annulus, is provided with external hexagonal structure; Bulge loop 6 places, annulus upper end are provided with upper-lower seal groove 5, and annulus lower end scrobicular ring 7 is guider ring; This form of structure is that six sides rotate while making top connection 1 rotation, more flexible.
It is circular ring structure that drilling rod connects cap 3, and circle ring inner wall diameter is identical with lower contact outer diameter, is provided with the anti-silk rotation of double end side's tooth screw thread 8 in the inwall of drilling rod connection cap 3, makes drilling rod connect cap 3 and can be rotatably connected with lower contact 2.The outer wall that drilling rod connects cap 3 is provided with draw-in groove 4, and top is provided with locking device 9.Upper street corner 1 connects rotation, rotation with lower contact 2 six sides, airtight connection place is also provided with sealing ring.
Using method, penetrates steel pipe drilling rod 10 to be inserted in top connection 1 and lower contact 2, after top connection 1 cover is embedded in lower contact 2, and drilling rod connected to cap 3 by draw-in groove 4, rotate airtight connections with lower contact 2, top arrangement is locked.In steel pipe drilling rod 10 and the junction of top connection 1, lower contact 2, carry out welded seal.
Good effect of the present invention is:
Safety index: because adopting tight joint mode in construction, the stability that has improved drilling rod rotation adds locking mechanism is set, commonly in construction fall, de-drilling rod and bury drills phenomenon controlled, greatly reduce construction accident and potential safety hazard.
Quality index: because of good airproof performance, in drilling construction, mud can flow directly to subdrilling head place, hole, make that hole wall is balanced, at the bottom of hole without sediment, without defects such as inclined hole are partially empty, technical indicator is improved at all, has guaranteed pore-forming quality.
Construction index: double end screw thread and the upper and lower drilling rod of connection are easy, and six side's planes of rotation are large, improved antitorque, anti-rock ability, joint fit sealing, mud smoothness, save the boring clear hole engineering time.
Economic indicator: because efficiency of construction improves, reduce by 15% through expenses such as the measuring and calculating energy and manpowers, because the technology mode connecting changes, strengthened mar proof, improve 50% application life of this product;
Because CGH fastening type engineering drilling rod coupling head product adopts tight joint technology mode, in the face of now construction, drilling pouring pile hole construction technology quality inspection standard high, require under rigorous condition, the fastening Novel drill rod coupling head of CGH research and development of products is born, and will be the first-selected product of this construction field.
