Description

Technical Field

[0001] This utility model relates to the technical field of pipeline connection devices, specifically to a flange rubber expansion joint reinforcement device. Background Technology

[0002] Common floating pipe docking mechanisms include flexible cylinders and flange mechanisms. Flange mechanisms are fixed at both ends of the flexible cylinder to dock with other pipes or pipe bodies. During use, this type of docking device may experience problems such as radial displacement of the flexible cylinder, leading to uneven stress and subsequent damage. Improvements are needed. Utility Model Content

[0003] To address at least one of the aforementioned technical deficiencies, this utility model provides the following technical solution:

[0004] This application discloses a flange rubber expansion joint reinforcement device, including a flange clamping mechanism and an elastic cylinder connecting two flange clamping mechanisms. It also includes an elastic guide mechanism spaced around the elastic cylinder, which connects the flange clamping mechanisms at both ends of the elastic cylinder. The elastic guide mechanism includes a guide rod, an elastic element, and a connecting plate. One end of the connecting plate is connected to the flange clamping mechanism, and the other end is elastically slidably connected to the guide rod in the axial direction of the elastic cylinder through the elastic element.

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

[0006] Furthermore, the connecting plate is sleeved with the guide rod, and the guide rod and the connecting plate are connected by an elastic element 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 element helps to promote the elastic cylinder to return to its original position and improve the structural stability.

[0007] Furthermore, a fixing member 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 members. The fixing members limit the movement of the connecting plate. The fixing members can be threaded onto the guide rod, or they can be fitted, welded, etc. The fixing members restrict the movement of the connecting plate, which facilitates assembly.

[0008] Furthermore, the fastener is threadedly connected to a guide rod extending axially along the elastic cylinder. The distance between adjacent fasteners can be adjusted to adjust the sliding range of the connecting plate. The threaded connection of the fastener can be adjusted by turning it to adjust the distance, 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 fasteners. The first connecting flange and the second connecting flange, together with the fasteners, clamp the end of the elastic cylinder, and the opening of the elastic cylinder corresponds to the opening of the corresponding connecting flange. The clamping of the two flanges with the fasteners facilitates assembly and forming.

[0010] Furthermore, the end peripheral wall of the elastic cylinder is provided with a protruding wing, which is clamped by the first connecting flange and the second connecting flange, so that the corresponding flange clamps the protruding wing to form a fixed shape and facilitates connection.

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

[0012] Furthermore, a connecting sleeve is provided on the outer side of the first connecting flange, with its end face facing away from the elastic cylinder protruding outward, to facilitate connection with other pipes through the connecting sleeve.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

This utility model improves the structure of the reinforcing device by adding an axially guiding elastic guiding mechanism, which can improve the axial stability of the elastic cylinder, reduce radial offset, 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 expansion joint reinforcement device includes a flange clamping mechanism 2, an elastic cylinder 1, and an elastic guiding mechanism 3. The elastic cylinder 1 may include a spherical body in the middle and cylindrical ends at both ends. The elastic cylinder connects the two flange clamping mechanisms 2. The flange clamping mechanisms 2 may be fixed at the beginning and end (i.e., cylindrical ends) of the elastic cylinder 1. The elastic guiding mechanisms 3 are installed around the elastic cylinder 1 at intervals. Two sets may be installed opposite each other, or four sets may be distributed in a rectangular shape. The elastic guiding mechanisms 3 connect the flange clamping mechanisms 2 at both ends of the elastic cylinder 1.

[0023] In this example, the elastic guiding mechanism 3 includes guide rods 31, elastic elements 34, and connecting plates 32. The guide rods 31 are spaced apart around the elastic cylinder 1 and extend along the axial direction of 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 end of the corresponding guide rod 31. The connecting plate 32 is elastically slidably connected to the guide rods 31 in the axial direction of the elastic cylinder 1 through the elastic elements 34.

[0024] Specifically, such as Figure 1 As shown, the connecting plate 32 is fitted and connected to the guide rod 31. A fixing member 33 is installed on the guide rod 31, using a nut as the fixing member 33. The fixing member 33 is threadedly connected to 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 fitted onto the guide rod 31 through the connecting hole and positioned between the two fixing members 33. The fixing members 33 restrict the movement of the connecting plate 32. A predetermined distance is spaced between the two fixing members 33 to allow the connecting plate to slide. A spring is used as an elastic element, directly fitted onto the end of the guide rod 31 and positioned between the two fixing members 33. The spring abuts against the connecting plate 32, creating an elastic sliding fit with the guide rod 31. The elastic element 34 can cause the connecting plate to return to its original position. The fixing members can also be screwed back and forth to adjust the distance between them, thereby increasing or decreasing the stroke of the connecting plate.

[0025] For the connection between the connecting plate and the flange clamping mechanism, any method is acceptable, such as welding. In this example, if... Figure 1 As shown, the flange clamping mechanism 2 includes a first connecting flange 21, a second connecting flange 22, and fasteners 23. The fasteners 23 include bolts and nuts. Through holes are axially formed at corresponding positions of the first connecting flange 21 and the second connecting flange 22. Through holes are 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 are aligned, the bolts in the fasteners 23 are passed through in sequence and fixed with nuts, thereby fixing the first connecting flange, the second connecting flange, and the connecting plate into one unit.

[0026] The elastic cylinder 1 has radially outwardly protruding wings 10 on its peripheral walls at both ends. When the elastic cylinder 1 is connected to the flange clamping mechanism 2, the ends of the elastic cylinder 1 are respectively inserted into the holes of the corresponding second connecting flange 22 and the protruding wings 10 are positioned between the first connecting flange 21 and the second connecting flange 22. While the bolts are tightened, the protruding wings 10 are clamped and fixed by the first connecting flange 21 and the second connecting flange 22, and the opening of the elastic cylinder 1 corresponds to the opening of the corresponding connecting flange.

[0027] To facilitate connection with other pipes, in this example, the first connecting flange 21 located on the outside and its end face away from the elastic cylinder 1 protrudes outward to form a cylinder, namely the connecting cylinder 24. When connecting, other pipes are fitted onto the connecting cylinder to complete the fixation.

[0028] With the axial guidance of the guide rod and the connecting plate, the axial stability of the elastic cylinder is enhanced, and radial displacement is restricted, thus improving structural stability.

[0029] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
