Technical Field

[0001] The invention relates to the technical field of pipeline connection devices, in particular to a flange rubber flexible joint reinforcer. Background Art

[0002] Common pipeline floating docking mechanisms include elastic tubes and flange mechanisms. Flange mechanisms are fixed at both ends of the elastic tube, and the flange mechanisms are used to dock with other pipelines or pipe bodies. During use, this type of docking device may have problems such as radial deviation of the elastic tube, resulting in uneven force and subsequent damage, and needs to be improved. Summary of the Invention

[0003] To solve at least one of the above technical deficiencies, the present invention provides the following technical solutions:

[0004] The present application document discloses a flange rubber flexible joint reinforcer, comprising a flange clamping mechanism and an elastic cylinder connecting the two flange clamping mechanisms, and also comprising an elastic guide mechanism spaced around the elastic cylinder, the flange clamping mechanisms at both ends of the elastic cylinder being connected by the elastic guide mechanism, the elastic guide mechanism comprising a guide rod, an elastic member, and a connecting plate, one end of the connecting plate being connected to the flange clamping mechanism and the other end being elastically slidably connected to the guide rod in the axial direction of the elastic cylinder through an elastic member.

[0005] The elastic cylinder is fixed by a flange clamping mechanism, and the flange clamping mechanism is axially guided by an elastic guide mechanism, thereby improving the axial stability of the elastic cylinder and limiting radial deviation, etc., which helps to improve stability and extend the service life of the elastic cylinder.

[0006] Furthermore, the connecting plate is sleeved and connected to the guide rod, and the guide rod and the connecting plate are connected by an elastic member to form an elastic sliding connection. For the sleeved connection, such as the guide rod passing through the hole on the connecting plate or the connecting plate passing through the hole on the guide rod, the elastic member helps to reset the elastic cylinder and improve the structural stability.

[0007] Furthermore, a fixing piece is provided on the guide rod, and a connecting hole is provided at the end of the connecting plate. The connecting plate is sleeved on the guide rod through the connecting hole and is located between the two fixing pieces. The movement of the connecting plate is limited by the fixing piece. The fixing piece, such as a nut, is threadedly engaged with the guide rod, or can be fixed by embedding or welding. The movement of the connecting plate is limited by the fixing piece to facilitate assembly and molding.

[0008] Furthermore, the fixing piece is threadedly connected to a guide rod extending axially along the elastic cylinder. The spacing between adjacent fixing pieces is adjusted to adjust the sliding range of the connecting plate. The threaded connection of the fixing piece can be adjusted by twisting to adjust the spacing, thereby adjusting the sliding range of the connecting plate, which is convenient to use.

[0009] Furthermore, the flange clamping mechanism includes a first connecting flange, a second connecting flange and a fastener. The first connecting flange and the second connecting flange cooperate with the fastener to clamp the end of the elastic cylinder, and the cylinder mouth of the elastic cylinder corresponds to the hole mouth of the corresponding connecting flange. The two flanges cooperate with the fastener to clamp and facilitate assembly and molding.

[0010] Furthermore, the elastic cylinder is provided with a convex wing at the peripheral wall of the end portion, and the convex wing is clamped by the first connecting flange and the second connecting flange, so that the corresponding flanges clamp the convex wing to form a fixed position and facilitate connection.

[0011] Furthermore, the fasteners include bolts and nuts, with the ends of the bolts passing through the holes at the first connecting flange, the second connecting flange and the end of the connecting plate in sequence and being fastened with nuts, thereby facilitating assembly and forming.

[0012] Furthermore, a connecting tube is provided on the outer side of the first connecting flange and on the end surface thereof facing away from the elastic cylinder, so as to facilitate connection with other pipelines through the connecting tube.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The present invention improves the structure of the reinforcer and adds an axially guided elastic guide mechanism, which can improve the axial stability of the elastic cylinder, reduce radial deviation, and extend the service life of the elastic cylinder.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1

[0022] like Figure 1 、 Figure 2 As shown, in this example, the flange rubber flexible joint reinforcer includes a flange clamping mechanism 2, an elastic cylinder 1, and an elastic guide mechanism 3. The elastic cylinder 1 includes a spherical body in the middle and cylindrical ends at both ends, and the two flange clamping mechanisms 2 are connected by the elastic cylinder. If the flange clamping mechanism 2 is fixed at the head and tail ends (i.e., the cylindrical ends) of the elastic cylinder 1, the elastic guide mechanisms 3 are installed at intervals around the elastic cylinder 1, such as two groups installed relative to each other, or four groups distributed in a rectangular shape, and the flange clamping mechanisms 2 at both ends of the elastic cylinder 1 are connected by the elastic guide mechanism 3.

[0023] In this example, the elastic guide mechanism 3 includes guide rods 31, elastic members 34, and connecting plates 32. The guide rods 31 are spaced apart around the elastic cylinder 1 and extend axially along the elastic cylinder 1. One end of the connecting plate 32 is connected to the flange clamping mechanism 2, and the other end is connected to the corresponding end of the guide rod 31. The connecting plate 32 is elastically slidably connected to the guide rod 31 in the axial direction of the elastic cylinder 1 via the elastic member 34.

[0024] Specific as Figure 1 As shown, the connecting plate 32 is sleeved and connected to the guide rod 31. A fixing member 33 is installed on the guide rod 31, and the fixing member 33 is a nut. The fixing member 33 is threadedly engaged with the end of the guide rod 31. A connecting hole is formed at the end of the connecting plate 32. The connecting plate 32 is sleeved on the guide rod 31 through the connecting hole and is located between the two fixing members 33. The fixing members 33 restrict the movement of the connecting plate 32. The two fixing members 33 are separated by a predetermined distance to allow the connecting plate to slide. A spring is used as an elastic member. The spring is directly sleeved on the end of the guide rod 31 and is located between the two fixing members 33. The spring abuts the connecting plate 32 to form an elastic sliding fit with the guide rod 31. The elastic member 34 can cause the connecting plate to return to its original position. The fixing members can also be twisted back and forth to adjust the spacing between the fixing members, thereby increasing or decreasing the travel of the connecting plate.

[0025] For the connection between the connecting plate and the flange clamping mechanism, any method such as welding can be used. In this example, Figure 1 As shown, the flange clamping mechanism 2 includes a first connecting flange 21, a second connecting flange 22 and a fastener 23. The fastener 23 includes bolts and nuts. Axial through holes are formed at corresponding positions of the first connecting flange 21 and the second connecting flange 22, and a through hole is also formed at the other end of the connecting plate 32. After the through holes on the first connecting flange 21, the second connecting flange 22 and the connecting plate 32 correspond to each other, the bolts in the fastener 23 are passed through in sequence and fixed with nuts, so that the first connecting flange, the second connecting flange and the connecting plate are fixed as a whole.

[0026] The circumferential walls at both ends of the elastic cylinder 1 are provided with radially outwardly protruding wings 10. When the elastic cylinder 1 is docked with the flange clamping mechanism 2, the head and tail ends of the elastic cylinder 1 are respectively inserted into the holes corresponding to the second connecting flange 22 and the convex wings 10 are located between the first connecting flange 21 and the second connecting flange 22. When the bolts are tightened, the convex wings 10 are clamped and fixed by the first connecting flange 21 and the second connecting flange 22, and the tube mouth of the elastic cylinder 1 corresponds to the hole mouth of the corresponding connecting flange.

[0027] To facilitate docking with other pipes, the first connecting flange 21 on the outside in this example has a convex surface at the end surface wall facing away from the elastic cylinder 1 to form a cylinder, namely a connecting cylinder 24. When docking, other pipes are put on the connecting cylinder to complete the fixation.

[0028] Under the axial guidance of the guide rod and the connecting plate, the axial stability of the elastic cylinder is enhanced, and the radial deviation is limited, thereby improving the structural stability.

[0029] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions based on the principles of the present invention are within the scope of protection of the present invention. It should be noted that improvements and modifications that do not depart from the principles of the present invention are within the scope of protection of the present invention.
