Description
Technical field
The present invention relates to drilling rig technique field, more specifically relate to the fixing reliable rig combined drive cover of a kind of draw key.
Background technology
The rig of pile foundation construction, if the unit head actuating sleeve course of work of conventional rotary drilling rig is to drive the driven wheel linking together with actuating sleeve body to rotate by the driving gear of gear-box, then drives and is inserted in interior aerial drilling rod and turns round together by being fixed on a plurality of draw keys in actuating sleeve endoporus groove.Actuating sleeve and drilling rod normally adopt the respective outer side edges of keyway.In work progress, the key bar on drilling rod frequently with the keyway friction of actuating sleeve, key bar easily weares and teares, and needs to change and repairs.Actuating sleeve in the market divides two kinds, and a kind of is integral drive cover, and this actuating sleeve inner chamber is processed into can be directly and the form of the keyway that coordinates of drilling rod, is single component, simple in structure, but after excessive wear, need integral replacing actuating sleeve, and cost is higher; Another is combined drive cover, by actuating sleeve body and relevant draw key, and block, the installations such as bolt form.After the wearing and tearing of this kind of combined drive cover key bar, can change separately draw key, cost is relatively cheap, has extended the application life of expensive actuating sleeve body.
At present traditional combined drive nested structure is for to be fixed on draw key on actuating sleeve endoporus groove by the many rows bolt being distributed on draw key, and there are the following problems for this kind of structure: screw processing trouble, and required precision is high; Draw key is fixing unreliable, easily loose or dislocation; Dismounting trouble will be dismantled during replacing, dozens of bolt is installed in the actuating sleeve endoporus of narrow space, and labour intensity is large, and length expends time in.
Summary of the invention
(1) technical problem that will solve
It is fixing unreliable that the technical problem to be solved in the present invention is exactly rig combined drive cover draw key of the prior art, easy loose or dislocation, and dismounting trouble, therefore need to provide a kind of draw key to fix reliable rig combined drive cover.
(2) technical scheme
In order to solve the problems of the technologies described above, the invention provides the fixing reliable rig combined drive cover of a kind of draw key, this actuating sleeve comprises: 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 up and down.
Preferably, the fixed stop in actuating sleeve body recess one end is changed to active block stop.
Preferably, described draw key, is all processed with one or more stopping step of certain matching relationship on fixed stop and active block stop.
Preferably, described stopping step is the combination of inclined-plane or inclined-plane and plane.
(3) beneficial effect
Draw key of the present invention is fixed reliable rig combined drive cover, compares fixing reliable, simple in structure, working stability, easy to maintenance, cost of manufacture is low with rig combined drive cover of the prior art.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

The specific embodiment
Below in conjunction with drawings and Examples, embodiments of the present invention are described in further detail.Following examples are used for illustrating the present invention, but can not be used for limiting the scope of the 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, upper and lower two ends are all fixed stops 6, there are the following problems for this structure: processing difficulties, 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 large, expense is high.But also will solve actuating sleeve body outboard gears case lubrication oil, by bolt hole, produce the problem of leaking; Draw key fixed form is unreliable, and easily loose or dislocation, produces construction and stop fault; Dozens of bolt will be dismantled, be installed to dismounting and change trouble in the actuating sleeve endoporus of narrow space during replacing, labour intensity is large, length expends time in.
As shown in Figure 2, combined drive cover 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, draw key 5 is fixed in the groove of actuating sleeve body 1 by fixed stop 6 and active block stop 7.On draw key 5, fixed stop 6, active block stop 7, be all processed with the step of certain matching relationship, by this stopping step, be fixed block 6, active block stop 7 of the two ends of draw key 5 simply and is reliably fixed in groove.Driven wheel and combined drive cover link together.In drilling rod 4 insert combined type actuating sleeves, utilize draw key 5 transmitting torques and the plus-pressure of key on drilling rod 4 and combined drive cover.
Draw key 5 can manufacture symmetrical structure, can be inverted to exchange completely and install.
During work, power head motor reductor drives driving gear rotation, and driving gear drives driven wheel to drive combined drive cover to rotate together with drilling rod.
When draw key 5 may wear to a certain degree, need to change, during replacing, only bolt 8 need be laid down, can change processing.The working space of dismantling this bolt is larger, and the bolt on single-unit activity block 78 only arranges 1-3 conventionally, simple to operation.
As shown in Figure 2, combined drive cover of the present invention processing is relatively simple, and draw key 5 is not all wanted processing bolt hole with actuating sleeve body 1, only block and draw key need be processed into stopping step; Fixed form is simple and reliable; The operating space that draw key 5 is changed is large, and bolt 8 quantity of dismounting are few, and on bolt, screw-down torque is also convenient.
Combined drive cover draw key installation form of the present invention also comprises following structure.
As shown in Figure 3, combined drive cover of the present invention is not limited to that one end is fixed, the form of one end activity, can design the frame mode that two ends block is active block stop 7.
As shown in Figure 4, the stopping step of combined drive cover block of the present invention can be plural many ledge structures.
As shown in Figure 5, the stopping step of combined drive cover block of the present invention can be the mode of inclined-plane or inclined-plane and plane combination.
Above embodiment is only for the present invention is described, but not limitation of the present invention.Although the present invention is had been described in detail with reference to embodiment, those of ordinary skill in the art is to be understood that, technical scheme of the present invention is carried out to various combinations, revises or is equal to replacement, do not depart from the spirit and scope of technical solution of the present invention, all should be encompassed in the middle of claim scope of the present invention.
