Description

Technical Field

[0001] The utility model relates to the field of rotary compensators, in particular to a rotary compensator which is easy to install. Background Art

[0002] The rotary compensator is a new type of pipeline compensation equipment that plays an important role in thermal pipelines and other industrial pipeline systems. Through proper installation and maintenance, the rotary compensator can effectively ensure the normal operation of the pipeline system, reduce stress and deformation caused by temperature changes, and extend the service life of the pipeline.

[0003] The existing patent CN217540064U discloses a rotary compensator with a card-type joint for easy splicing. The card seat of the utility model is provided with a movable groove, and the load-bearing wrench matches the movable groove. The bottom of the movable groove is provided with a magnetic base. The load-bearing wrench is made of stainless steel, and the bottom of the load-bearing wrench is provided with an anti-disengagement ring. The top of the load-bearing wrench is provided with a pull buckle. When the load-bearing wrench is not in use, it retracts into the movable groove, and the magnetic base at the bottom of the movable groove can firmly lock the load-bearing wrench in the movable groove. When the load-bearing wrench needs to be used, the load-bearing wrench is manually removed from the movable groove through the pull buckle to assist the rotation of the card-type flange 1 and the card-type flange 2.

[0004] The above technical solution sets a clasp flange 1 and a clasp flange 2, and installs the auxiliary clasp flange 1 on the clasp flange 2 so that the bayonet is locked in the inside of the slot, thereby clasping the clasp flange 1 and the clasp flange 2, and controlling the position relationship between the load-bearing wrench and the movable slot by the pull buckle to assist the rotation of the clasp flange 1 and the clasp flange 2, thereby solving the problem that the flange connection needs to be fixed with screws, and the installation and removal of the screws are relatively laborious.

[0005] However, in actual use, the following deficiencies still exist. For example, when the rotary compensator needs to be welded to an external pipe, since no guide structure is installed on the outer pipe and the inner pipe of the rotary compensator, deviations are easily generated between the pipe and the outer pipe and the inner pipe during the docking process, which may lead to poor welding and leakage, and is not conducive to improving the installation efficiency of the rotary compensator. Therefore, the utility model proposes a rotary compensator that is easy to install. Utility Model Content

[0006] The purpose of the utility model is to solve the shortcomings of the prior art and provide a rotary compensator that is easy to install.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a rotary compensator that is easy to install, comprising an outer tube and a sealing assembly, the sealing assembly being arranged on the outer tube, a rotating assembly being arranged inside the outer tube, and a guide assembly being arranged on the rotating assembly; the rotating assembly comprising an inner tube and a bearing, the bearing being arranged inside the outer tube, and the inner tube being arranged inside the bearing; the guide assembly comprising a base and a limit plate, the base being arranged at one end away from each other on the inner tube and the outer tube, the bottom of the base being an arc-shaped structure, the top of the base being an inclined structure, the limit plate being arranged at the top of the base, a slider being fixedly connected to the side of the limit plate close to the base, a slide groove being provided on the side of the base close to the slider, and the limit plate being slidably connected to the base through the slider and the slide groove.

[0008] As a preferred embodiment, a clamping plate 1 is provided on one end of the inner tube and the outer tube close to the base, and a clamping plate 2 is provided on both sides of the clamping plate 1. A hinge is fixedly connected between the clamping plate 1 and the clamping plate 2, and the clamping plate 2 is rotatably connected to the clamping plate 1 through the hinge. The clamping plate 1 and the clamping plate 2 are both fixedly connected to the base.

[0009] The technical effect of adopting the above technical solution is that the base and the limit plate can be removed from the outer tube and the inner tube through the clamping plate 1 and the clamping plate 2, which facilitates the subsequent fixed welding of the rotary compensator.

[0010] As a preferred embodiment, a clip is fixedly connected to the second clipping plate near one side of the first clipping plate, and a socket is fixedly connected to the second clipping plate near the other side of the first clipping plate. The first and second clipping plates are fixedly connected to the inner tube via the clip and the socket.

[0011] The technical effect of adopting the above technical solution is that it facilitates the rapid disassembly and assembly of the base, which is conducive to improving work efficiency.

[0012] As a preferred embodiment, anti-slip pads are provided on one side of the first and second clamping plates close to the inner tube and the outer tube.

[0013] The technical effect of adopting the above technical solution is to increase the friction between the first and second clamping plates and the inner and outer tubes, thereby preventing the guide assembly from accidentally slipping off the rotary compensator, which is beneficial to improving the stability of the rotary compensator.

[0014] As a preferred embodiment, the sealing assembly includes a sleeve and a sealing filler, the sealing filler is arranged inside the outer tube, the sleeve is arranged on one end of the outer tube close to the sealing filler, the sleeve and the outer tube are provided with fixing bolts, and the sleeve is fixedly connected to the outer tube through the fixing bolts.

[0015] The technical effect of adopting the above technical solution is to increase the sealing performance of the rotary compensator, and then use the fixing bolt to seal the sealing filler, thereby further increasing the sealing performance of the rotary compensator.

[0016] As a preferred embodiment, an inner groove is opened on the inner side of the outer tube close to the bearing, the bearing is rotatably connected to the inner groove, the inner tube is threadedly connected to the bearing, and a bolt is threadedly connected to one end of the outer tube close to the inner groove.

[0017] The technical effect of adopting the above technical solution is that the bolt clamps the bearing and rotates the inner tube so that the inner tube can be quickly threaded into the bearing. Thus, while maintaining the rotational flexibility of the inner tube, the inner tube can be quickly installed inside the outer tube, which is conducive to further improving the installation efficiency of the rotary compensator.

[0018] Compared with the prior art, the advantages and positive effects of the present invention are:

[0019] By setting a guide component and a limit plate on the inner tube and the outer tube, when the rotary compensator needs to be welded to the external pipe, the pipe and the rotary compensator can be aligned first. During the alignment process, the external pipe is inserted into the limit plate, and then the limit plate is pushed. Through the cooperation of the slider and the slide groove, the limit plate is rotated on the base. This can calibrate whether the outer tube and the inner tube are aligned with the pipe. Next, the rotary compensator and the pipe are preliminarily welded along the gap between the limit plates, and the connection parts are position-welded to fix the position of the rotary compensator. This method solves the problem of easy deviation between the pipe and the outer tube and the inner tube during the docking process, avoids leakage due to poor welding, and is also beneficial to improving the installation efficiency of the rotary compensator.

[0020] By setting up a rotating assembly, when the bolt is installed on the outer tube, one end of it will contact the surface of the bearing. This contact enables the bolt to fix the bearing. Then, by rotating the inner tube, it can be quickly connected to the bearing through threads. This process not only maintains the rotational flexibility of the inner tube, but also enables the inner tube to be quickly installed into the interior of the outer tube. This method effectively improves the installation efficiency of the rotary compensator. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figure 1 - Figure 4 As shown, this embodiment provides a technical solution: a rotary compensator that is easy to install, including an outer tube 1 and a sealing component 4, characterized in that the sealing component 4 is arranged on the outer tube 1, a rotating component 2 is arranged inside the outer tube 1, and a guide component 3 is arranged on the rotating component 2; Figure 4 As shown, the rotating assembly 2 includes an inner tube 21 and a bearing 22. The bearing 22 is arranged inside the outer tube 1, and the inner tube 21 is arranged inside the bearing 22. Figure 2As shown, the guide assembly 3 includes a base 31 and a limit plate 32. The base 31 is arranged on one end of the inner tube 21 and the outer tube 1 away from each other. The bottom of the base 31 is an arc-shaped structure, and the top of the base 31 is an inclined structure. The limit plate 32 is arranged on the top of the base 31. A slider 35 is fixedly connected to the limit plate 32 on the side close to the base 31. A slide groove 36 is provided on the side of the base 31 close to the slider 35. The limit plate 32 is slidably connected to the base 31 through the slider 35 and the slide groove 36. By arranging the limit plate 32 on the inner tube 21 and the outer tube 1, when the rotary compensator needs to be welded to the external pipe, the pipe is first aligned with the rotary compensator. During the alignment process, the external pipe is inserted into the inside of the limit plate 32, and the pipe is moved along the limit plate The top of 32 is formed by the inclined surface sliding of the inclined structure, so that the three limit plates 32 cooperate to guide the pipeline to the outer tube 1 and the inner tube 21 at the same time, and then push the limit plate 32, and the limit plate 32 cooperates with the slide 35 and the slide groove 36 to rotate on the base 31, so that the limit plate 32 rotates along the outer tube 1, and calibrates whether the outer tube 1 and the inner tube 21 are aligned with the pipeline, so that the pipeline is quickly aligned and fitted with the rotary compensator, and then the rotary compensator and the pipeline are preliminarily welded along the gap between the limit plates 32, and the connection parts are position-welded to fix the position of the rotary compensator, thereby solving the problem of easy deviation between the pipeline and the outer tube 1 and the inner tube 21 during the docking process, avoiding leakage due to poor welding, and at the same time, helping to improve the installation efficiency of the rotary compensator.

[0028] Furthermore, Figure 2 As shown, a clamping plate 1 33 is provided on one end of the inner tube 21 and the outer tube 1 close to the base 31, and a clamping plate 2 34 is provided on both sides of the clamping plate 1 33. A hinge 37 is fixedly connected between the clamping plate 1 33 and the clamping plate 2 34. The clamping plate 2 34 is rotatably connected to the clamping plate 1 33 through the hinge 37. The clamping plate 1 33 and the clamping plate 2 34 are both fixedly connected to the base 31. By pushing the clamping plate 2 34, the clamping plate 2 34 is rotated along the clamping plate 1 33 through the hinge 37, so that the base 31 and the limit plate 32 can be removed from the outer tube 1 and the inner tube 21 through the clamping plate 1 33 and the clamping plate 2 34, so as to facilitate the subsequent fixed welding of the rotary compensator.

[0029] Furthermore, Figure 2 As shown, a snap 38 is fixedly connected to the snap plate 2 34 on one side of the snap plate 1 33, and a socket 39 is fixedly connected to the snap plate 2 34 on the other side of the snap plate 1 33. The snap plate 1 33 and the snap plate 2 34 are fixedly connected to the inner tube 21 through the snap 38 and the socket 39. By installing the nut on the snap 38, the snap plate 1 33 and the snap plate 2 34 are fixed to the outer tube 1 and the inner tube 21 through the snap 38 and the socket 39. After removing the nut, the snap plate 1 33 and the snap plate 2 34 can be removed, thereby facilitating the quick disassembly and assembly of the base 31 and improving work efficiency.

[0030] Furthermore, Figure 2 As shown, anti-slip pads 5 are provided on one side of the clamping plate 1 33 and the clamping plate 2 34 close to the inner tube 21 and the outer tube 1. By making the anti-slip pads 5 fit against the inner tube 21, the friction between the clamping plate 1 33, the clamping plate 2 34 and the inner tube 21 and the outer tube 1 is increased, thereby preventing the guide assembly 3 from accidentally slipping off the rotary compensator, which is beneficial to improving the stability of the rotary compensator.

[0031] Furthermore, Figure 4 As shown, the sealing assembly 4 includes a sleeve 41 and a sealing filler 43. The sealing filler 43 is arranged inside the outer tube 1, and the sleeve 41 is arranged on one end of the outer tube 1 close to the sealing filler 43. A fixing bolt 42 is provided on the sleeve 41 and the outer tube 1. The sleeve 41 is fixedly connected to the outer tube 1 through the fixing bolt 42. By installing the sealing filler 43 between the outer tube 1 and the inner tube 21, the sealing performance of the rotary compensator can be increased. Thereafter, the sealing filler 43 is sealed using the fixing bolt 42, thereby further increasing the sealing performance of the rotary compensator.

[0032] In order to further improve the installation efficiency of the rotary compensator, such as Figure 4 As shown, an inner groove 23 is provided on one side of the inner part of the outer tube 1 near the bearing 22, and the bearing 22 is rotatably connected to the inner part of the inner groove 23. The inner tube 21 is threadedly connected to the bearing 22, and a bolt 24 is threadedly connected to one end of the outer tube 1 near the inner groove 23. When the bolt 24 is installed on the outer tube 1, one end of the bolt 24 will contact the surface of the bearing 22, so that the bolt 24 will clamp the bearing 22, and the inner tube 21 is rotated so that the inner tube 21 can be quickly threadedly connected to the bearing 22. Therefore, while maintaining the rotational flexibility of the inner tube 21, the inner tube 21 can be quickly installed inside the outer tube 1, which is conducive to further improving the installation efficiency of the rotary compensator.

[0033] Working principle: Figure 1 - Figure 4As shown, when in use, first place the inner tube 21 inside the outer tube 1, rotate the inner tube 21 so that the inner tube 21 is threadedly connected to the bearing 22 through the thread, then push the second clamping plate 34, so that the second clamping plate 34 rotates along the first clamping plate 33 through the hinge 37, fit the first clamping plate 33 and the second clamping plate 34 on the outer tube 1 and the inner tube 21, and then install the nut on the buckle 38, so that the buckle 38 and the clamping seat 39 are fixed, and then the base 31 and the limit plate 32 are fixed to the rotary compensator through the first clamping plate 33 and the second clamping plate 34. Then, align the pipeline with the rotary compensator. During the alignment process, make the outer The pipe of the part is inserted into the inside of the limit plate 32. The three limit plates 32 cooperate to guide the pipe to the outer pipe 1 and the inner pipe 21. Then the limit plate 32 is pushed. The limit plate 32 rotates on the base 31 through the slider 35 and the slide groove 36, so that the limit plate 32 rotates along the outer pipe 1. The outer pipe 1 and the rotating component 2 are calibrated to see whether they are aligned with the pipe, so that the pipe is quickly aligned and fitted with the rotary compensator. Then, the rotary compensator and the pipe are preliminarily welded along the gap between the limit plates 32, and the connection parts are position-welded. Finally, the guide component 3 is removed from the rotary compensator, and the rotary compensator is subsequently fixed and welded.
