Abstract
The utility model discloses a rigid self-supporting structure for a rubber short pipe. The rigid self-supporting structure comprises lug plates which extend out from steel flanges at the two ends of the rubber short pipe in the radial direction, and double end studs, wherein the opposite lug plates located on the two flanges are provided with right opposite through holes, the two ends of the double end studs penetrate through the right opposite through holes, and the double end studs are both in threaded connection with nuts capable of clamping the lug plates on the two sides of each lug plate. By virtue of the structure, a rigid support is formed between the flanges at the two ends of the rubber short pipe to improve the integral rigidity of the rubber short pipe, and therefore, the rubber short pipe can still work stably even under the condition that a neighboring metal pipe or a neighboring pipe fitting is not provided with an effective support to largely reduce vibration, so that the service life of the rubber short pipe and the service life of the pipeline fitting can be prolonged.
Description
Technical field
The utility model relates to a kind of supporting structure of rubber short tube.
Background technique
In large-scale pipe-line system (as the suction mud pipe-line system of dredger), usually can between two joint metal tubes of some position of pipe-line system or metal tube and piping attachment (as valve), rubber short tube be set, and by flange, rubber short tube and adjacent metal tube or piping attachment are linked together, to facilitate the installation and removal of metal tube and piping attachment, but the rigidity by rubber short tube is lower, so, in the process of installing, as installation personnel is noted not, perhaps due to spatial constraints, effective support is not set on adjacent metal tube or annex, in the process of pipe-line system work, rubber short tube and adjacent metal tube, piping attachment may produce obvious vibration together.Once this vibration occurs, the working life of rubber pipe and piping attachment will be reduced.
Summary of the invention
The purpose of this utility model is to provide a kind of rigidity self supporting structure of rubber short tube, and it can improve the integral rigidity of rubber short tube, thereby reduces rubber short tube because in use occurring that obviously vibration reduces the possibility in its working life.
The rigidity self supporting structure of a kind of rubber short tube described in the utility model, comprise respectively the otic placode radially overhanging from the steel flange at rubber short tube two ends, be positioned on otic placode relative on two flanges have over against through hole, the two ends of stud through over against through hole, stud all is bolted with the nut that otic placode can be clamped in the both sides of each otic placode.
The utility model is because the through hole of the radially overhanging relative otic placode of the flange from the rubber short tube two ends is inserted with stud, and be bolted with the nut that otic placode can be clamped in the position that stud is positioned at each otic placode both sides, thereby form the support of rigidity between the flange at rubber short tube two ends, improve the integral rigidity of rubber short tube, even make rubber short tube in the situation that its adjacent metal tube, piping attachment do not arrange effective support, still can keep stable operation, greatly alleviate vibration, thereby can improve working life rubber short tube and piping attachment.
The accompanying drawing explanation
Fig. 1 is structural drawing of the present utility model.
Fig. 2 is the sectional view of Fig. 1 along A-A direction.
Embodiment
As Fig. 1, shown in Fig. 2, the rigidity self supporting structure of described rubber short tube, comprise respectively the otic placode 3 radially overhanging from the steel flange 2 at rubber short tube 1 two ends, and stud 4, be positioned on the relative otic placode 3 on two flanges 2 have over against through hole 31, the two ends of stud 4 through over against through hole 31, described stud 4 all is bolted with the nut 5 that otic placode 3 can be clamped in the both sides of each otic placode 3, thereby form the support of rigidity between the flange at rubber short tube 1 two ends, improve the integral rigidity of rubber short tube 1, even make rubber short tube 1 in the situation that its adjacent metal tube or piping attachment (not shown) do not arrange effective support, still can keep stable operation, greatly alleviate vibration, thereby can improve working life rubber short tube 1 and piping attachment (as valve).In addition, the utility model is by turning the nut 5 on stud 4 one ends or two ends, can or elongate (rubber short tube 1 can be elongated when nut 5 is turned toward the direction that deviates from stud 4 middle parts) by rubber short tube 1 axial shortening (rubber short tube 1 can be shortened when the direction at nut 5 past stud 4 middle parts is turned), thereby when mounted rubber short tube be shortened to facilitate the installation and removal of rubber short tube.
As shown in Figure 2, for preventing in use, occur that nut 5 becomes flexible and the integral rigidity of reduction rubber short tube 1, and then make rubber short tube 1 obviously vibration occur and affect working life of rubber short tube 1 and piping attachment, can adopt non-resilient locking measure to nut 5, as, nut 5 can adopt lock nut or double nut.And loosening for further preventing nut 5, can between nut 5 and otic placode 3, plain washer be set at stud.
Shown in the Fig. 1 of institute, Fig. 2, the power that the otic placode 3 on described each flange 2 and the quantity of stud 4 can be born according to rubber short tube 1 with and rigid demand determine, more than being generally three covers, be illustrated in figure 1 the situation of six covers.
Claims (4)
1. the rigidity self supporting structure of a rubber short tube, it is characterized in that: comprise respectively the otic placode radially overhanging from the steel flange at rubber short tube two ends, be positioned on otic placode relative on two flanges have over against through hole, the two ends of stud through over against through hole, stud has the nut that otic placode can be clamped in the equal scyewed joint in the both sides of each otic placode.
2. the rigidity self supporting structure of rubber short tube according to claim 1, is characterized in that: described nut employing lock nut or double nut.
3. according to the rigidity self supporting structure of claim 1 or 2 described rubber short tubes, it is characterized in that: between described nut and otic placode, be provided with plain washer.
4. the rigidity self supporting structure of rubber short tube according to claim 1, it is characterized in that: the otic placode on each flange and the quantity of stud are more than three covers.
