Description
Technical field
The invention belongs to hydraulic engineering field, be specifically related to a kind of extractor of hydraulic engineering, its classification belongs to No. E02D9/02 classification that name is called " method with withdrawing ".
Background technology
Extractor refers to the machine pulled out by the stake hammering into underground, and existing extractor is generally heavy-duty machines, and strength is very large, and efficiency is very high, but cost is also very high, is not suitable for small hydraulic project (such as, keeping in repair small-sized dam).
Summary of the invention
The object of the invention is to the extractor proposing a kind of hydraulic engineering for the deficiencies in the prior art, be adapted to small hydraulic project, in order to cost-saving, its power uses manpower.
The present invention uses technical scheme to solve problem: its structure is formed primarily of 4 automatic locking dops 10, chuck 11, jack 6, bases 8; Automatic locking dop 10 is positioned on chuck 11; Chuck 11 is positioned at jack 6 top.
Further illustrate 1: locking dop 10 is made up of bail 1, rotating shaft 3, support ear 2 automatically, and the head of bail 1 is
Hemispherical, its centre of sphere and bail 1 bar portion's axes coincide are also positioned at head and junction, bar portion.
Further illustrate 2: chuck 11 uses screw 4 fixing by four card articles 5 and forms.
Further illustrate 3: card article 5 has groove 12, using as size adjusting, is that extractor can adapt to stake not of uniform size.
Further illustrate 4: pile pulling principle of the present invention is, as shown in Fig. 1, chuck 11 is used to surround stake 9, and allow the bail 1 of four automatic locking dops 10 upwards lean against in stake 9 in 45 degree of angles, and after tightening all screws 4, the handle 7 of manual operation jack 6, the head of jack 6 is made to increase, due to the effect of frictional force, stake 9 can be blocked by automatic locking dop 10 inflexibly, and stake 9 can be extracted a ground part by jack; When jack 6 be raised to the highest after, retraction operation is carried out to jack 6, because the locking direction of automatic locking dop 10 is unidirectional, when jack 6 bounces back, automatic locking dop 10 can unclamp automatically, and relatively stake 9 is glided a segment distance, after waiting jack 6 to bounce back completely, operating grip 7 pairs of jack 6 carry out lifting operation a part are extracted in stake 9 again; Cycling, until stake 9 is pulled out completely.
Further illustrate 5: the unidirectional automatic locking principle of work and power of locking dop 10 is automatically: according to further illustrating 1, rotating shaft 3 is the distance that the intersection point of bail 1 shaft axis and hemisphere surface is arrived in rotating shaft 3 to bail 1 head surface maximum length; Mention illustrating in 4 further " when jack 6 does not raise; the bail 1 of four automatic locking dops 10 upwards leans against in stake 9 in 45 degree of angles ", that is, bail 1 bar portion's axis and hemisphere surface intersection point do not touch stake 9, just illustrate that rotating shaft 3 is less than bail 1 maximum length to the distance on stake 9 surface yet; When jack 6 rises, bail 1 relatively stake 9 moves upward, bail 1 is subject to downward frictional force, because rotating shaft 3 is less than bail 1 maximum length (bar portion axis direction) to stake 9 surface distance, so friction factor constantly increases, until stake 9 starts to move upward in chassis 8 relatively, namely stake 9 starts to be stirred; After stake 9 beginning is stirred, the friction factor between automatic stuck dop 10 and stake 9 maintains inconvenience.
Further illustrate 6: the inverse principle further illustrating the principle described in 5 is known, when jack 6 bounces back, automatic locking dop 10 can unclamp automatically.
Further illustrate 7: because jack 6 is very ripe prior arts, therefore repeat no more.
Novelty of the present invention is: the extractor creating a kind of hydraulic engineering, wherein aim at pile pulling and the automatic locking dop novelty with unidirectional locking function designed is given prominence to, the mode of unidirectional locking dop and jack collaborative work pile pulling also has novelty.
Practicality of the present invention is: the present invention is adapted to small hydraulic project, as a kind of aid, eliminates little engineer operation pile pulling difficult, the embarrassment do not calculated again with large machine.
Accompanying drawing explanation
Fig. 1 is an embodiment of the present invention.
Accompanying drawing special instruction 1: in order to illustrated succinctly clear, Fig. 1 eliminates a lot of label in the scope that Machine Design personnel can understand, such as: label 4 refers to all screws, in Fig. 1, there is a lot of screw, if all screws are all put on 4, knowledge figure can be disturbed.
Accompanying drawing special instruction 2: in order to theory of mechanics of the present invention can be expressed more clearly, Fig. 1 eliminates non-essential numerous and diverse part when charting, the such as overall machine on Fig. 1 left side, automatic locking bail 10 only draws two, be in order to illustrated clear like this, allow observer be easier to understand the principle of unidirectional automatic locking.
Accompanying drawing special instruction 3: express theory of mechanics of the present invention more clearly in order to more enough, Fig. 1 eliminates for qualified Machine Design teacher when charting, without the need to repeating just accessible syndeton; Such as, in figure, automatic locking bail 10 there are 4 screw holes, screw is that how to screw on, chuck and jack connected mode.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described:
Fig. 1 and embodiment of the present invention, its content did detailed description in summary of the invention, therefore no longer made its theory of mechanics and repeating.
1-3 is illustrated from summary of the invention and accompanying drawing, the present invention is as a mechanical invention, important innovations point of the present invention is: the theory of mechanics automatically blocking stake 9 of locking dop 10 automatically, and locking dop 10 coordinates jack 6 to extract the theory of mechanics of stake 9 automatically; Main openly object of the present invention should be Machine Design teacher with Fundamentals of Machine Design knowledge, this manual coordinates accompanying drawing to make detailed explanation to theory of mechanics of the present invention with summary of the invention, as qualified Machine Design teacher, will design machinery of the present invention after understanding theory of mechanics of the present invention is the very simple thing of part, thus this Figure of description do not locate in detail do not affect disclosed adequacy.
