Abstract
The utility model relates to a locking and dismounting device of a locking nut of a reaming drill bit center pipe, comprising a screw, a supporting wing, a locking nut, a connecting component, a chain plate, an L-shaped supporting plate and a knob. The locking nut can be combined and/or separated from a drill center pipe by screwing; and the supporting wing is welded on the locking nut and connected with the screw by the connecting component and a knob which is used for locking or dismounting the locking nut of the center pipe by adjusting the locking nut. The device divides the structure of the drill center pipe for transferring torque and tension into two parts, is beneficial to the detection of the reaming drill bit, is convenient to rapidly mount or dismount the center pipe, lightens the labor intensity of workers and reduces the use of auxiliary equipment.
Description
Technical field
The utility model relates to a kind of locking and provision for disengagement of mine mechanism, particularly a kind of nut check and provision for disengagement that is used for anti-well reamer bit of bored well central tube.
Background technology
Raise boring machine is a kind of common mine mechanism, and raise boring machine reaming bit central tube is to tighten together with bit body, and main effect is pulling force and the moment of torsion that transmits top rig dynamical system.The reaming bit central tube of tradition rig and the mode that bit body is fastenedly connected mainly are the tapered sleeve self-locking structures, and it utilizes the contact friction force of tapered sleeve and the alignment pin of its underpart to carry out the moment of torsion transmission, makes drill bit be rotated brokenly rock.
But because the self-locking property of conical surface self-locking is better, be unfavorable for opening, so rather inconvenience of the replacing of the central tube in the traditional structure, it is time-consuming relatively to require great effort when central tube is changed, and also is unfavorable for the maintenance of drill bit and the maintenance of whole raise boring machine device simultaneously.
Summary of the invention
The purpose of this utility model is to provide nut check of a kind of reaming bit central tube and provision for disengagement, is convenient in the reaming bit maintenance process important force transferring structures such as central tube be changed and overhauled.
Solution of the present utility model is a kind of locking and provision for disengagement that is used for anti-well drilling well with reaming bit central tube locking nut of design, it comprises leading screw, braced wing, locking nut, connecting elements, carrier bar, L type fagging and knob, locking nut can and/or separate with the combination of rig central tube, braced wing is welded on the described locking nut, leading screw is connected with carrier bar by connecting elements with braced wing, adjusting knob is used for locking and the dismounting that the adjusting lock nut finishes the central tube locking nut, and connecting elements comprises screw bolt and nut.
During installation, after the screw thread of locking big nut and drill bit bottom screwed, the knob of adjusting leading screw can guarantee the locking of locking nut in the broken rock process of reaming bit when reaching certain tensioning; During dismounting, by changing the permanent position of leading screw in the drill bit bottom, translation-angle, the back after the locking big nut is loosening, can be carried out the dismantlement work of nut to the knob reinforcing, and is time saving and energy saving for the maintenance of reaming bit central tube.
Major advantage of the present utility model is that the structure with central tube transfer torque and pulling force is divided into two bodies, and is quite favourable for the maintenance of reaming bit, is convenient to carry out fast the installation and removal of central tube, reduces the use of labor strength and auxiliary equipment.

The specific embodiment
As shown in Figures 1 and 2, the utility model is to be used for locking and the provision for disengagement 3 of anti-well drilling well with reaming bit central tube locking nut, this device comprises leading screw 9, braced wing 11, locking nut 12, connecting elements, carrier bar 14, L type fagging 15 and knob 16, locking nut 12 can and/or separate with 6 combinations of rig central tube, braced wing 11 is welded on the described locking nut 12, leading screw 9 is connected with carrier bar 14 by connecting elements with braced wing 11, and adjusting knob 16 is used for locking and the dismounting that adjusting lock nut 12 finishes the central tube locking nut.Connecting elements comprises bolt 10 and nut 13.Described device 3 is fixed on the bit body lower shoe 2 of reaming bit 1 bottom by bolt 17.The central tube 6 of raise boring machine is by torsion pass spline 7, reaming bit 1 top moment of torsion is passed to taper spline housing 8 and the bit body that is fixed together with straight pin 5 in overlap 4, make the broken rock of reaming bit 1 rotation.After screwing, the screw thread of locking nut 12 and central tube 6 bottoms is fastened on the bottom of reaming bit body 1, the power of creeping into that provides reaming bit to creep into.
Shown in Figure 3 in conjunction with reference, after locking nut 12 screws with central tube 6, with bolt 10, nut 13 and carrier bar 14 leading screw 9 and the braced wing 11 that is welded on the locking nut 12 are coupled together, simultaneously " L " fagging 15 is fixed on locked position 18, adjusting knob 16 makes nut check and provision for disengagement be in tension, oppositely can guarantee that locking nut 12 does not oppositely get loose in the reaming process.
If need carry out the maintenance or the replacing of reaming bit central tube 6, then removed position 19 places of reservation will be placed on after the dismounting of " L " fagging, by adjusting knob 16, make the pulling force that locking nut 12 is subjected to oppositely getting loose, after locking nut 12 became flexible, after this device can being removed, easy removal was fallen locking nut, central tube can directly be extracted out by top, so that maintenance and replacing.
