Abstract
The invention discloses a clamp device with adjustable elasticity and belongs to the pipeline fixing sealing equipment field. The clamp device is characterized in that an arch-shaped clamp (6), a rotation adjustment mechanism connected with the arc-shaped clamp (6), and a soft body tension .mechanism arranged to be matched with the rotation adjustment mechanism, the bottom end of the rotation adjustment mechanism is fixed at the upper end of the arc-shaped clamp (6), a connecting piece of the soft body tension mechanism is sleeved on and is matched with a rotating rod on the rotation adjustment mechanism, and the elasticity of the soft body tension mechanism is adjusted through adjustments of the rotation adjustment mechanism. The clamp device with adjustable elasticity can be applied to pipelines different in thickness and can be freely adjusted in pipeline clamping degree. Due to the fact that the arc length of the arc-shaped clamp is small, the arc-shaped clamp with the same arc length can be applied to pipelines with radiuses in a large range. All parts can be freely replaced according to actual on-site conditions. The clamp device with the adjustable elasticity has the advantages of being simple in structure, convenient to operate, and reliable in sealing state.
Description
Technical field
The adjustable clip device of degree of tightness belongs to pipeline fixing seal apparatus field.Be specifically related to a kind of pipeline and adjustable clip device of degree of tightness that adapts to different thicknesses.
Background technique
In the current technology, when connecting the hard pipeline of two kinds of different thicknesses and conveying material, when particularly soft pipeline is used in the joint, the way of normal employing is the outside that the soft pipeline two ends is set in both sides hard pipeline, clip is installed then, to play the effect that is tightly connected at the soft pipeline two ends.The clip form of using always as shown in Figure 4 at present, staggered relatively by two sections semicircular arc clips, two semicircular clip outsides are extruded with the joint, pass the joint by bolt pipeline is locked, but this class clip has following defective: (1) sealing effect is unreliable, if the semi-circle of both sides is too short, then the gap can appear in the joint at two ends, the problem of material appears leaking easily, long if the semi-circle of both sides arranges, and then the phenomenon that clip can't effectively tighten can appear.(2) need make the clip of different radii according to the radius of pipeline, increase cost of production.(3) easy generation deformation of long duration, thus the phenomenon that occurs fluffing is unfavorable for long-time use.(4) be not suitable for the thicker pipeline of radius.But also have the clip that some degrees of tightness are regulated now on the market, but be not suitable for the sealing of thicker pipeline equally, and can not be applicable to the pipeline that thickness is different.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, a kind of pipeline that various thicknesses are different and can the adjustable clip device of freely regulated degree of tightness to the chucking degree of pipeline of can being applicable to is provided.

Embodiment
Fig. 1 ~ 3rd, most preferred embodiment of the present invention, the present invention will be further described below in conjunction with accompanying drawing 1 ~ 4.
Shown in Fig. 1 ~ 3, the adjustable clip device of degree of tightness of the present invention is made up of following components: arc clip 6, rotation controlling mechanism and software tensioning mechanism, wherein arc clip 6 is for respectively having a draw-in groove in the middle of circular-arc and its two ends.Draw-in groove is that rectangular and its inner segment are arc.
The rotation controlling mechanism comprises: rotating nut 1, link 2, adjusting screw rod 3 and screw rod fixed base 5.Screw rod fixed base 5 is fixed on the position on arc top, arc clip 6 top, and screw rod fixed base 5 central positions have circular hole.Adjusting screw rod 3 surfaces are provided with screw thread, and its bottom is stretched into the circular hole that is positioned at screw rod fixed base 5 central positions and can be rotated at circular hole, and the rotating nut 1 of vertical placement is fixedly arranged at the top of adjusting screw rod 3.
The software tensioning mechanism comprises link 2 and tight rope 4.Link shown in Fig. 2 ~ 3 comprises tensioning hook 7, traveling nut 8 and set screw nut 9.Traveling nut 8 horizontal positioned, its inboard screw thread can match with the screw thread on adjusting screw rod 3 surfaces.Tensioning hook 7 vertically is fixed on the left side of traveling nut 8, and the draw-in groove of its coupler body upwards; Set screw nut 9 is similarly vertical setting, is fixed on the right side of traveling nut 8.Link 2 screwed on the adjusting screw rod 3 before rotating nut 1 is fixed to adjusting screw rod 3.Tight rope 4 one ends are the fixed end that is fixed in the set screw nut 9, the other end movable end, and the end of movable end is ring-type, can be articulated on the coupler body of tensioning hook 7.
Concrete working procedure is as follows: when needs seal pipeline opening, at first on the inboard corresponding body that is placed on pipeline with arc clip 6, fixed end with tight rope 4 is starting point then, at first tight rope 4 is placed in the draw-in groove of arc clip 6 of its adjacent side, then the rope body of tight rope 4 is carried out circumference to pipeline and twine.Twine after some circles according to the radius of the length of tight rope 4 and pipeline, tight rope 4 is stuck in the draw-in groove of arc clip 6 opposite sides, and the annulus of tight rope 4 movable ends is articulated on the coupler body of tensioning hook 7, this moment, tight rope 4 was in the state of half tensioning.
In the circular hole in the middle of the dwang insertion rotating nut 1, be that fulcrum rotates rotating nut 1 with rotating nut 1 then.Rotating nut 1 drives adjusting screw rod 3 when rotating and rotates, relatively rotate between adjusting screw rod 3 and the link 2 this moment, because the screw thread of link 2 matches with the screw thread on adjusting screw rod 3 surfaces, so when adjusting screw rod 3 constantly rotates, link 2 constantly rises, and the tight rope 4 that will be fixed on its both sides in the time of rising is constantly strained, when tension rope 4 is tightened to maximum rating, stop the rotation to rotating nut 1, finish the chucking sealing to pipeline.When needs loosen body when safeguarding, only need rotating nut 1 taken off to counter-rotation and with tight rope 4 and get final product.
In the present embodiment, what set screw nut 9 adopted is common nut, also can adopt the parts of other ring-types to replace; What tensioning hook 7 adopted is common half nut, also can adopt other hook-like assembly units to replace.What tight rope 4 adopted is wire rope, also can adopt the intensity of the other types body of restricting reliably to replace, be fixing mode simultaneously in the present invention between tight rope 4 one ends and the set screw nut 9, also can adopt temporary fixed mode, when conveniently extraordinarily thick or special thin pipeline being sealed tight rope 4 be changed.
In the present embodiment, fixing for welding between rotating nut 1 and the adjusting screw rod 3, also rotating nut 1 can be omitted.Can be the plug of the polygonal (as square) of standard this moment with the top design of adjusting screw rod 3, utilize an end to be welded with the dwang of the sleeve that can match with this polygonal plug then, this sleeve is inserted in adjusting screw rod 3 tops, adjusting screw rod 3 is rotated.
The above only is preferred embodiment of the present invention, is not to be the restriction of the present invention being made other form, and any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solution of the present invention content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment does, still belongs to the protection domain of technical solution of the present invention according to technical spirit of the present invention.
