Description

Reliable rig combined drive set fixed by a kind of draw key
Technical field
The present invention relates to drilling rig technique field, be more particularly to a kind of draw key and fix reliable rig combined drive set.
Background technology
The rig of the pile foundation construction such as unit head actuating sleeve work process of conventional rotary drilling rig is to be driven the driving gear rotation linked together with actuating sleeve body by the driving gear of gear-box, then is driven by the multiple draw keys being fixed in actuating sleeve endoporus groove and be inserted in interior aerial drilling rod and turn round together.Actuating sleeve and drilling rod are typically with the respective outer side edges of keyway.In work progress, the spline on drilling rod frequently with the keyway friction of actuating sleeve, spline is easily worn and torn, and needs to change and repair.Actuating sleeve in the market divides two kinds, and one is integral drive set, and this actuating sleeve embedded SMA actuators becomes can be with directly and the form of keyway of drilling rod cooperation, for single component, simple in construction, but after excessive wear, needs integral replacing actuating sleeve, relatively costly;Another is combined drive set, and i.e. by actuating sleeve body and relevant draw key, block, bolt etc. is installed and formed.Draw key, relative inexpensiveness can be individually replaced after this kind of combined drive set spline abrasion, extend the service life of the actuating sleeve body of costliness.
The most traditional combined drive nested structure is to be fixed on actuating sleeve endoporus groove by draw key by the multiple rows of bolt being distributed on draw key, and there are the following problems for this kind of structure: screw processing trouble, required precision is high;Draw key is fixed unreliable, easy loose or dislocation;Dismounting trouble, to dismantle in the actuating sleeve endoporus of narrow space during replacing, install dozens of bolt, and labor intensity is big, expends the time long.
Summary of the invention
(1) to solve the technical problem that
The technical problem to be solved in the present invention be exactly rig combined drive of the prior art set draw key fix unreliable, easy loose or dislocation, dismounting trouble, it is therefore desirable to provide a kind of draw key to fix reliable rig combined drive set.
(2) technical scheme
In order to solve above-mentioned technical problem, the invention provides a kind of draw key and fix reliable rig combined drive set, this actuating sleeve includes: actuating sleeve body, draw key, fixed stop, active block stop, bolt;Fixed stop is fixed on one end of actuating sleeve body recess, and active block stop is bolted on the other end of actuating sleeve body recess, and draw key is fixed in the groove of actuating sleeve body by fixed stop and active block stop.
Preferably, described draw key is symmetrical above and below.
Preferably, active block stop will be changed at the fixed stop of actuating sleeve body recess one end.
Preferably, described draw key, fixed stop and active block stop are all machined with one or more stopping step of certain matching relationship.
Preferably, described stopping step is the combination on inclined-plane or inclined-plane and plane.
(3) beneficial effect
Reliable rig combined drive set fixed by the draw key of the present invention, and fixing reliable compared with rig combined drive set of the prior art, simple in construction, working stability, easy to maintenance, cost of manufacture is low.
Accompanying drawing explanation
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in describing below is only some embodiments of the present invention, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.

Detailed description of the invention
With embodiment, embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings.Following example are used for illustrating the present invention, but can not be used for limiting the scope of the present invention.
As shown in Figure 1, current combined drive nested structure is that draw key 2 is arranged in actuating sleeve body 1 groove by bolt 3, two ends are all fixed stops 6 up and down, there are the following problems for this structure: processing difficulties, and on actuating sleeve body 1 and draw key 2, dozens of position of related features requires the fixing hole difficulty of processing of strict bolt 3 greatly, costly.But also the problem that actuating sleeve outer body gear box lubricating oil to be solved produces leakage by bolt hole;Draw key fixed form is unreliable, easy loose or dislocation, produces construction and stops fault;Dismounting and change bothers, and to dismantle, installs dozens of bolt during replacing in the actuating sleeve endoporus of narrow space, and labor intensity is big, it is long to expend the time.
As shown in Figure 2, the combined drive set draw key mounting means of the present invention, fixed stop 6 is fixed on one end of actuating sleeve body 1 groove, active block stop 7 is fixed on the other end of actuating sleeve body 1 groove by bolt 8, and draw key 5 is fixed in the groove of actuating sleeve body 1 by fixed stop 6 and active block stop 7.All being machined with the step of certain matching relationship on draw key 5, fixed stop 6, active block stop 7, by this stopping step, the two ends of draw key 5 are simply and reliably fixing in a groove by fixed stop 6, active block stop 7.Gear is driven to link together with combined drive set.In drilling rod 4 insert combined type actuating sleeve, the draw key 5 of the key on drilling rod 4 and combined drive set is utilized to transmit moment of torsion and plus-pressure.
Draw key 5 may be produced that symmetrical structure, can be inverted exchange completely and install.
During work, power head motor reductor drives driving gear to rotate, and driving gear drives gear driven combined drive set to rotate together with drilling rod.
Need when draw key 5 may wear to a certain degree to be replaced, only bolt 8 need to be laid down during replacing, can be replaced processing.The work space dismantling this bolt is relatively big, and the bolt 8 on single-unit activity block 7 generally only arranges 1-3, simple to operation.
As shown in Figure 2, combined drive of the present invention set processing is relatively easy, and draw key 5 and actuating sleeve body 1 all do not want processing bolt hole, only block and draw key need to be processed into stopping step;Fixed form is simple and reliable;The working place that draw key 5 is changed is big, and bolt 8 quantity of dismounting is few, and on bolt, screw-down torque is also convenient for.
The combined drive set draw key installation form of the present invention also comprises following structure.
As it is shown on figure 3, the combined drive set of the present invention is not limited to the form that one end is fixed, one end is movable, the frame mode that two ends block is active block stop 7 can be designed.
As shown in Figure 4, the stopping step of the combined drive set block of the present invention can be plural multi-step structure.
As it is shown in figure 5, the stopping step of the combined drive set block of the present invention can be the mode of inclined-plane or inclined-plane and plane combination.
Embodiment of above is merely to illustrate the present invention, rather than limitation of the present invention.Although the present invention being described in detail with reference to embodiment, it will be understood by those within the art that, technical scheme is carried out various combination, amendment or equivalent, without departure from the spirit and scope of technical solution of the present invention, all should contain in the middle of scope of the presently claimed invention.
