Abstract
An anti-locking drilling rod basket sleeve device belongs to the technical field of drilling tool device for mine. When drilling is performed for the soft coal rock, and particularly when deep-hole boring is performed, a hole collapse phenomenon is easily generated. Once the hole collapse causes coal rock squeezing and locking of the drilling rod, the operation can not performed continuously and the retreating of the drilling rod is difficult. The technical solution of the utility model is characterized in that: a notch (6) is respectively provided at two sides of a drilling rod sleeve (9) and a drilling rod sleeve (10); an upper cover (1) and a bottom support (2) are respectively provided at the upper position and the lower position of the notches (6); the drilling rod sleeve (9) is connected with the drilling rod sleeve (10) through plug connection; a projection ring (11) is respectively provided on the drilling rod sleeve (9) and the drilling rod sleeve (10); and two pieces of opening-closing connectors (7) cover the space between the drilling rod sleeve (9) and the drilling rod sleeve (10). The advantage of the anti-locking drilling rod basket sleeve device is characterized in that: two ends of each drilling rod sleeve are set to pluggable shapes and are fixed with open-close type locking connectors, so that the sleeve and the drilling rod are connected synchronously for depth drilling, and the operation is not affected when the hole collapse phenomenon occurs.
Description
Technical field: the utility model relates to drilling tool device technique field, mine, is a kind of anti-lock drilling rod gaily decorated basket casing bit more specifically.
Background technology: colliery cherry coal rock boring, the hole phenomenon of collapsing especially appears during deep well drilling easily, the hole had both caused the coal petrography extruding can't continue operation to the drilling rod locking in case occur collapsing, it is also very difficult to want to withdraw from drilling rod, often forming useless hole causes waste waste material in man-hour to influence job schedule, the hole of collapsing is again inevitable common phenomenon, existing at present employing large aperture steel pipe is taked the deep step by step technical scheme of reducing method, but workload is too big, the high operating efficiency of operating cost is extremely low, moreover the deep hole that surpasses more than 30 meters can't be realized, so but the requirement of the degree of depth of gas extraction hole need be eager needs at the anti-lock boring rod set that designs a kind of drilling deep hole more than 50 meters.
Summary of the invention: for overcoming above-mentioned shortcoming, the purpose of this utility model is a kind of anti-lock drilling rod gaily decorated basket casing bit of design.Its technical scheme is: the both sides of drilling rod sleeve pipe and drilling rod sleeve pipe have neutral, upper-lower position in neutral is respectively loam cake and collet, be socket connection between drilling rod sleeve pipe and the drilling rod sleeve pipe, be respectively arranged with bulge loop on drilling rod sleeve pipe and the drilling rod sleeve pipe, be stamped two folding connectors between drilling rod sleeve pipe and the drilling rod sleeve pipe, bulge loop is embedded in the annular groove of two folding connectors, is wound with spring on two folding connectors.The advantage of this utility model is: reasonable in design, novelty is skillfully constructed, the drilling rod sleeve pipe two ends shape of being arranged to peg graft is fixed with opening-closing type locking connector, can make sleeve pipe be connected drilling depth synchronously like this with drilling rod, meeting the hole phenomenon of collapsing does not influence work yet, and the laborsaving high efficiency of saving money can be made a call to deep hole more than 50 meters.
Description of drawings: Fig. 1 front view, Fig. 2 are at Figure 1A-A place sectional view, and Fig. 3 is at Figure 1B-B place sectional view, and Fig. 4 is at Fig. 1 C-C place sectional view, the view of Fig. 5 for making progress at Fig. 1 D.In the accompanying drawing: 1, loam cake, 2, collet, 3, the concavity docking port, 4, the auger stem hole, 5, support bar, 6, neutral, 7, the folding connector, 8, spring, 9, the drilling rod sleeve pipe, 10, the drilling rod sleeve pipe, 11, bulge loop.
The specific embodiment: the both sides of drilling rod sleeve pipe 9 and drilling rod sleeve pipe 10 have neutral 6, upper-lower position in neutral 6 is respectively loam cake 1 and collet 2, be socket connection between drilling rod sleeve pipe 9 and the drilling rod sleeve pipe 10, be respectively arranged with bulge loop 11 on drilling rod sleeve pipe 9 and the drilling rod sleeve pipe 10, be stamped two folding connectors 7 between drilling rod sleeve pipe 9 and the drilling rod sleeve pipe 10, bulge loop 11 is embedded in the annular groove of two folding connectors 7, is wound with spring 8 on two folding connectors 7.Drilling rod sleeve pipe 9 and drilling rod sleeve pipe 10 both sides are slit into gaily decorated basket shape formation neutral 6 and support bar 5, auger stem off-centre is packed in drilling rod sleeve pipe 9 and the drilling rod sleeve pipe 10,4 places are installed in drill bit on the drilling rod in the auger stem hole, the left end of foot piece one end drilling rod sleeve pipe 9 docks with rig, the length of every drilling rod sleeve pipe 9 or drilling rod sleeve pipe 10 is identical with the length of every joint auger stem, shape is arranged to peg graft with fixing formation opening-closing type connector in their bulge loop 11 of the insertion of the annular groove in two folding connectors 7 and with spring 8 in all the other drilling rod sleeve pipe two ends, can make the drilling rod sleeve pipe be connected drilling depth synchronously like this with auger stem, grafting interconnects with the opening-closing type connector and fixes between drilling rod sleeve pipe and the drilling rod sleeve pipe, drilling rod docks with the rig rotating shaft, like this with the synchronous drilling depth of drilling rod, also do not influence and continue to creep into even if meet the hole phenomenon of collapsing, the coal petrography that makes both sides, the hole extruding of collapsing makes the spiral of coal petrography by neutral 6 contact drilling rods be cut slagging through loam cake 1 guiding and discharges supported influence of top pressure and creep into operation.
