Detailed description of the invention
Shown in as clear in Fig. 1 and Fig. 6, mainly comprise joint arm Part I 1, joint arm Part II 2 and wedge coupling mechanism according to the dismantled and assembled operation bar of present pre-ferred embodiments.Joint arm Part I 1 and joint arm Part II 2 are formed by being disconnected by certain joint arm of operation bar, and be coupled to each other removably by special wedge coupling mechanism.Wedge coupling mechanism comprises each face (will state in more detail hereinafter) and wedge 3 of being respectively formed at joint arm Part I 1 and save in the interface end of arm Part II 2.Wedge 3 can contact with the wedge contact surface in each face described, thus joint arm Part I 1 and joint arm Part II 2 is coupled to each other removably.
Refer to Fig. 2, wherein show in detail the shape of the interface end of joint arm Part I 1 and joint arm Part II 2.Clearly visible from figure, the shape of both interface end is symmetrical.Here " symmetry " is that the first half of dactylus arm Part I 1 is identical with the shape of the first half with the latter half of joint arm Part II 2 respectively with the shape of the latter half.In other words, if turn upside down by joint arm Part II 2, the shape so saving arm Part I 1 and joint arm Part II 2 is exactly identical.Adopt the identical interface end of shape can significantly improve the versatility of operation bar of the present invention.
Because the shape essence of the interface end of two joint arm section is identical, below will be illustrated to save arm Part I part 1.As shown in Figure 2, the interface end saving arm Part I 1 comprises first to the tenth 1A ~ 1J totally ten face.First surface 1A, the 3rd 1C, octahedral 1H and the tenth 1J are vertical plane.Fourth face 1D and the 7th 1G is positioned at the horizontal plane on same horizontal plane, and they are arranged on as vertical plane the 3rd between 1C and octahedral 1H.Second 1B and the 9th 1I is for connecting inclined-plane, and they are separately positioned between first surface 1A and the 3rd 1C as vertical plane, and are arranged between octahedral 1H and the tenth 1J as vertical plane.5th 1E and the 6th 1F is two crossing wedge contact surfaces (being inclined-plane in this embodiment), and they are arranged between fourth face 1D and the 7th 1G as horizontal plane.
As mentioned above, the symmetrical shape of the interface end of joint arm Part I 1 and joint arm Part II 2, in other words, each face (first to the tenth 2A ~ 2J) saving the interface end of arm Part II 2 is arranged symmetrically with each face (first to the tenth 1A ~ 1J) of the interface end of joint arm Part I 1.
As shown in Figure 2, on joint arm Part I 1, second 1B as inclined-plane, fourth face 1D and the 7th 1G as horizontal plane and the 9th I as inclined-plane are three main conjunction planes of the present invention.More particularly, second 1B saving arm Part I 1 forms with the 9th 2I of joint arm Part II 2 the conjunction plane 1B-2I contacted with each other; The horizontal plane (fourth face 1D, the 7th 1G) of joint arm Part I 1 forms with the horizontal plane (the 7th 2G, fourth face 2D) of joint arm Part II 2 the conjunction plane 1D-2G-1G-2D contacted with each other respectively; 9th I1 of joint arm Part I 1 forms conjunction plane 1I-2B with second 2B of joint arm Part II 2.
As shown in Figure 3, three main conjunction plane 1B-2I, 1D-2G-1G-2D and 1I-2B are main stress surfaces, bear the substantially all stressed of coupling mechanism.
Get back to Fig. 2, four vertical plane 1A on joint arm Part I 1, four vertical planes 2J, 2H, 2C and 2A on 1C, 1H and 1J and joint arm Part II 2 are corresponding thereto non-coupled face.When two joint arm section 1,2 normally connect, between each vertical plane, leave certain gap.Therefore, as shown in Figure 3, when wedge compresses, the thrust connecting contact surface can be regulated.
As Fig. 2 and shown in composition graphs 3 ~ Fig. 6, the 5th 1E as wedge contact surface on joint arm Part I 1 forms rectangle taper hole with the 5th 2E as wedge contact surface of the 6th 1F on joint arm Part II 2 together with the 6th 2F, and its shape and wedge 3 match.After installing wedge in the bellmouth formed at this, wedge contact surface 1E, 1F and 2E, 2F, by the corresponding intimate surface contact with wedge, form tight fit.Especially, the width of wedge contact surface E1, E2 should be corresponding with the width of wedge 3, to ensure can promote joint arm Part I 1 when squeezing into wedge and save arm Part II 2 to make move toward one another, winner's conjunction plane is adjacent to.
As shown in Fig. 4 ~ Fig. 6, strengthening mechanism 4 can be equipped with in the connection place of operation bar, thus the connection guaranteeing to save arm Part I 1 and joint arm Part II 2 is more reliable and safety.Strengthening mechanism 4 can adopt known various fastening structures, fastens access node structure as illustrated in the drawing.
As shown in Figure 7, the thickness of wedge 3 used in this embodiment remains unchanged, but its width changes along its length.In other words, the long limit of wedge 3 has a certain degree relative to longitudinal axis, and this angle meets the self-locking requirement of material, loosens to prevent wedge 3.
According to preferred embodiment of the present invention, be that certain joint arm of operation bar is disconnected, and be processed into dismantled and assembled wedge coupling mechanism as shown in the figure.Therefore, follow-uply can loading onto different parts, as disconnected on Section of four arm, Section of five arm can be loaded onto, or Section of five and the 6th arm.It is preferred that leave hydraulic quick coupling in connection place (interface end), conveniently access hydraulic system.Generally, when job area increases, longer operation bar joint arm can be replaced with; When job area is less, shorter operation bar joint arm can be replaced with; The jib form of two joints or more joint can be replaced with when job requirements flexibility; Arrange when needed, the annex of such as fire branch and so on can be replaced with rapidly.Therefore, operation bar of the present invention can realize configuration flexibly by wedge coupling mechanism and dismantle fast and assemble.
Although be more than described in detail in conjunction with preferred embodiment of the present invention, those of ordinary skill in the art should make various equivalent conversion and change on the basis of above disclosure.Such as, for meeting specific demand, the shape of the interface end of two joint arm section also can be made mutual difference; Each faces in the interface end of two joint arm section also can be other layouts, as vertical plane, the quantity that connects inclined-plane and horizontal plane can change; The thickness of wedge also can be change, etc.Therefore, protection scope of the present invention should be limited by appended claims.
