Description

Technical Field

[0001] The present invention relates to the technical field of constant force support hangers, and in particular to an anti-sway fastening device for a constant force support hanger. Background Art

[0002] As we all know, the constant force spring hanger is a mechanical device designed according to the principle of torque balance. It mainly uses a lever system to fix the constant force hanger at the pipeline installation position through a fixed frame and fix it through a hanger. It also converts the elastic force of the spring into a supporting force for the pipeline or equipment. When the pipeline or equipment is displaced, the lever system will automatically adjust the degree of tension or compression of the spring according to the change in displacement, so that the spring force and the gravity of the pipeline or equipment are balanced at different positions, thereby achieving a constant supporting force.

[0003] The problem with the existing technology is that although the existing constant force support hanger can effectively provide balanced support for the pipeline, the hanger rod of the constant force support hanger in the existing technology sometimes swings relative to the structural body or the pipeline. This shaking may be caused by factors such as pipeline vibration, thermal expansion and contraction displacement, fluid impact or external load changes. Especially when the hanger rod is long, the rigidity is insufficient or there is a gap in the connection node, the swing amplitude will be more obvious.

[0004] Based on the above-mentioned situation, we found that it is difficult for the constant force support hanger in the existing technology to avoid the swing of the hanger. Even if it is restricted by a metal hoop-like structure, the frequent collision of the restriction structure with the hanger may cause deformation and damage to both, and it is difficult to adjust the anti-sway degree of the hanger according to the allowable swing range, which is inconvenient to use. Therefore, we propose an anti-sway fastening device for the constant force support hanger, which can effectively limit the swing of the hanger at the bottom of the constant force support hanger and can be flexibly adjusted according to the allowable anti-sway degree. Summary of the Invention

[0005] In response to the deficiencies of the prior art, the present invention provides an anti-sway fastening device for a constant force support hanger, which has the advantages of being able to effectively limit the sway of the hanger at the bottom of the constant force support hanger and being able to be flexibly adjusted according to the allowable anti-sway degree.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: an anti-sway fastening device for a constant force support hanger, comprising a fixed frame and a hanger rod installed inside the fixed frame, two anti-sway plates are provided at the bottom of the fixed frame, and a fastener is provided between the two anti-sway plates; The anti-sway disc includes a filling disc, the inner side of which is movably connected to a blocking disc, the side of the blocking disc close to the suspension rod is provided with an integrally formed blocking protrusion, the side of the blocking disc away from the suspension rod is provided with an integrally formed sliding block portion, the inner side of the sliding block portion is provided with a circulation hole, the side of the sliding block portion away from the suspension rod is provided with a return spring, both ends of the return spring are fixedly connected with a push piece, the push piece away from the suspension rod is fixedly connected to the filling disc, the inner side of the filling disc is filled with viscous oil, the inner side of the filling disc is fixedly connected to a sealing ring, and the sealing ring is in contact with the blocking disc; The top and bottom of the filling tray and the bottom of the fastener are all fixedly connected with connecting flanges, and the connecting flange at the bottom of the fastener and the connecting flange at the top of the bottom filling tray are installed by bolts.

[0007] The above technical solution is adopted, and a fixed frame is provided to install the constant force support hanger in the required position, and the hanger and the bottom pipe connector are connected to the pipe to support the pipe, and the anti-sway plate provided on the outside of the hanger is used to limit the sway of the hanger. When the hanger is affected by the pipe or the external environment and causes it to sway or swing, its surface will contact the inner side of the anti-sway plate of the anti-sway plate, and the anti-sway plate will be displaced along the inner side of the filling plate after being subjected to force. At this time, due to the viscous oil filled in the filling plate, the oil will be pushed to flow between the inner side of the filling plate and the slider part when the anti-sway plate is displaced, and it will also flow along the inner side of the flow hole of the slider part, thereby playing a damping and buffering effect. Compared with the rigid restriction of the position of the hanger, it has a certain buffering effect while preventing the hanger from swaying, which can avoid collision damage to the hanger or the anti-sway plate. At this time, the reset spring will also be deformed because the push plate is pressed by the slider part, and gradually push the anti-sway plate to reset when the force stops, so as to push the hanger to reset through the inner side of the anti-sway plate, effectively reducing the sway amplitude between the hanger and the fixed frame.

[0008] The present invention is further configured as follows: the bottom of the fixed frame is fixedly connected to two vertical poles, the outer side of the filling tray is fixedly connected to an assembly piece, and the assembly piece is sleeved on the outer side of the vertical poles.

[0009] By adopting the above technical solution, vertical poles are provided to cooperate with the assembly plates to install and limit the filling tray, so as to avoid the two anti-sway trays being out of axial alignment when being installed, resulting in failure to use them normally.

[0010] The present invention is further configured as follows: an external thread is provided on the outer side of the vertical pole; hand screw sleeves are provided on the top and bottom of the assembly piece; and the hand screw sleeves are connected to the outer side of the vertical pole by threads.

[0011] By adopting the above technical solution, by setting an external thread in conjunction with a hand-tightened screw sleeve, when the filling plate is moved to the desired position through the assembly piece, the hand-tightened screw sleeve can be rotated so that the top and bottom hand-tightened screw sleeves can fix the assembly piece in the current position, thereby achieving the effect of fixing the structure.

[0012] The present invention is further configured as follows: the fastener includes a slide and a main frame, the outer side of the main frame is rotatably connected to six rotating sleeves, and the inner side of the rotating sleeve is rotatably connected to a fastening rod.

[0013] By adopting the above technical solution, a slide is set to cooperate with the main frame and the rotating sleeve. If it is necessary to further limit the movable range of the boom, the fastening rod can be rotated along the rotating sleeve on the outside of the main frame. Multiple fastening rods can limit the moving range of the boom when approaching or moving away from the boom. When the boom contacts the fastening rod, the main frame, slide and anti-sway disk connected to it that are in contact with the fastening rod will be subjected to force, thereby triggering the buffering, anti-sway and reset effects of the anti-sway disk.

[0014] The present invention is further configured as follows: an adjustment ring is slidably connected to the outer side of the slide, a side rod is rotatably connected to the outer side of the adjustment ring, and a side of the side rod away from the adjustment ring is rotatably connected to the fastening rod.

[0015] By adopting the above technical solution, by setting an adjustment ring, when the position of the fastening rod needs to be adjusted, the adjustment ring can be slid vertically along the slide to synchronously push and pull the fastening rod through the side rod, thereby achieving the effect of simultaneously moving multiple fastening rods synchronously close to or away from the vertical rod's hanger.

[0016] The present invention is further configured as follows: the bottom of the slide is fixedly connected to an extension frame, the bottom of the extension frame is fixedly connected to the connecting flange, the bottom of the outer side of the slide is fixedly connected to a transmission sleeve, the inner side of the transmission sleeve is threadedly connected to a screw rod, and the top of the screw rod is rotatably connected to the adjustment ring.

[0017] By adopting the above technical solution, an extension frame is set up to extend the distance between the slide and the bottom filling plate to ensure that there is sufficient distance for the screw rod to move. When the position of the adjustment ring needs to be adjusted, the screw rod can be rotated along the transmission sleeve, and the adjustment ring connected to it will be vertically raised and lowered along the slide.

[0018] The present invention is further configured as follows: a connecting sleeve is rotatably connected to the top of the fastening rod, a fastening claw is fixedly connected to a side of the connecting sleeve close to the suspension rod, and a contact pad is provided on the outer side of the fastening claw.

[0019] By adopting the above technical solution, a connecting sleeve is provided in combination with a fastening claw. The fastening claw is used to make the belt fastening rod directly contact the suspension rod, thereby increasing the number of force points and the force area, and performing preliminary buffering through the contact pad to further reduce the damage caused by contact between structures.

[0020] The present invention is further configured as follows: the fastening claw is configured as an arc shape, the contact pad is bonded to the side of the fastening claw away from the connecting sleeve, the slide is made of an annular frame and six cylindrical metal rods welded together, and the inner side of the adjustment ring is provided with a hole for use with the metal rod.

[0021] By adopting the above technical solution, by setting up arc-shaped fastening claws, more force points can be obtained compared to direct contact through the fastening rod, thereby reducing the probability that the boom cannot be triggered when it swings between two adjacent fastening rods. The slide made by welding the set annular frame and six cylindrical metal rods can limit the adjustment ring when it is driven to move by the screw.

[0022] The present invention is further configured as follows: a connecting torsion spring is fixedly connected to the inner side of the connecting sleeve, and the connecting torsion spring is fixedly connected to the fastening rod on a side close to the fastening rod.

[0023] By adopting the above technical solution and setting a connecting torsion spring, when the connecting sleeve and the fastening claw contact the boom, the fastening claw under force and the connecting sleeve connected thereto will rotate and fit onto the surface of the boom, changing the point contact into line contact and increasing the contact area. At this time, the torsion spring accumulates force and rebounds after stopping contact to push the connecting sleeve and the fastening claw to reset.

[0024] The present invention is further configured as follows: an observation slot is provided on the top of the filling tray, and an observation window is fixedly connected to the inner side of the observation slot.

[0025] By adopting the above technical solution, by providing an observation slot in combination with an observation window, it is convenient for personnel to observe the internal structure of the filling tray, so as to facilitate timely maintenance or correction.

[0026] Compared with the prior art, the present invention provides an anti-sway fastening device for a constant force support hanger, which has the following beneficial effects: The anti-sway fastening device of the constant force support hanger is used to install the constant force support hanger in the required position by setting a fixed frame, and connects the pipe with the bottom pipe connector through the hanger and the pipe to support the pipe, and the anti-sway plate provided on the outside of the hanger is used to limit the sway of the hanger. When the hanger is affected by the pipe or the external environment and causes the hanger to sway or swing, its surface will contact the inner side of the anti-sway plate of the anti-sway plate, and the anti-sway plate will move along the inner side of the filling plate after being subjected to force. At this time, due to the viscous oil filled in the filling plate, the anti-sway plate During displacement, the oil will be pushed to flow between the inner side of the filling plate and the slider, and will also flow along the inner side of the flow hole of the slider, thereby playing a damping and buffering effect. Compared with the rigid restriction of the position of the hanger, it has a certain buffering effect while preventing the hanger from shaking, which can avoid collision damage to the hanger or the blocking plate. At this time, the return spring will also be deformed because the push piece is pressed by the slider, and will gradually push the blocking plate to reset when the force stops, so as to push the hanger to reset through the inner side of the blocking plate, effectively reducing the shaking amplitude between the hanger and the fixed frame.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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.

[0030] Example 1: See also Figure 1-6 , an anti-sway fastening device for a constant force support hanger, comprising a fixed frame 1 and a hanger rod 2 installed inside the fixed frame 1, two anti-sway plates 3 are provided at the bottom of the fixed frame 1, and a fastener 4 is provided between the two anti-sway plates 3; The anti-sway disc 3 includes a filling disc 31, the inner side of which is movably connected to a blocking disc 32, the side of the blocking disc 32 close to the boom 2 is provided with an integrally formed blocking protrusion, the side of the blocking disc 32 away from the boom 2 is provided with an integrally formed slider portion 33, the inner side of the slider portion 33 is provided with a flow hole 34, the side of the slider portion 33 away from the boom 2 is provided with a return spring 35, both ends of the return spring 35 are fixedly connected to a push piece 36, the push piece 36 away from the boom 2 is fixedly connected to the filling disc 31, the inner side of the filling disc 31 is filled with viscous oil, the inner side of the filling disc 31 is fixedly connected to a sealing ring 37, and the sealing ring 37 is in contact with the blocking disc 32; The top and bottom of the filling tray 31 and the bottom of the fastener 4 are fixedly connected with connecting flanges, and the connecting flange at the bottom of the fastener 4 and the connecting flange at the top of the bottom filling tray 31 are installed by bolts; A fixed frame 1 is provided for installing the constant force support hanger at the desired position, and the hanger 2 is connected to the bottom pipe connector and the pipe to support the pipe, and the anti-sway plate 3 provided on the outside of the hanger 2 is used to limit the swaying of the hanger 2. When the hanger 2 is affected by the pipe or the external environment and causes it to sway or swing, its surface will contact the inner side of the anti-sway plate 32 of the anti-sway plate 3, and the anti-sway plate 32 will be displaced along the inner side of the filling plate 31 after being subjected to force. At this time, due to the viscous oil filled in the filling plate 31, the oil will be pushed in the filling plate when the anti-sway plate 32 is displaced. Flow occurs between the inner side of 31 and the slider portion 33, and also flows along the inner side of the flow hole 34 of the slider portion 33, thereby playing a damping and buffering effect. Compared with the rigid restriction on the position of the hanger 2, it prevents the hanger 2 from shaking while having a certain buffering effect to avoid collision damage to the hanger 2 or the blocking plate 32. At this time, the return spring 35 will also be deformed because the push piece 36 is pressed by the slider portion 33, and gradually push the blocking plate 32 to reset when the force stops, and at the same time push the hanger 2 to reset through the inner side of the blocking plate 32, effectively reducing the shaking amplitude between the hanger 2 and the fixed frame 1.

[0031] Among them, the bottom of the fixed frame 1 is fixedly connected to two vertical poles 5, and the outer side of the filling disk 31 is fixedly connected with an assembly piece 6, which is sleeved on the outer side of the vertical pole 5. The vertical pole 5 is set to cooperate with the assembly piece 6 to install and limit the filling disk 31 to avoid the two anti-sway disks 3 being not aligned when installed, resulting in inability to use normally. The outer side of the vertical pole 5 is provided with an external thread, and the top and bottom of the assembly piece 6 are provided with a hand-tightened screw sleeve 7, which is threadedly connected to the outer side of the vertical pole 5. By setting the external thread and cooperating with the hand-tightened screw sleeve 7, when the filling disk 31 is moved to the desired position through the assembly piece 6, the hand-tightened screw sleeve 7 can be rotated so that the top and bottom hand-tightened screw sleeves 7 can fix the assembly piece 6 in the current position, so as to achieve the effect of fixing the structure. An observation groove is provided on the top of the filling disk 31, and an observation window 14 is fixedly connected to the inner side of the observation groove. By setting the observation groove and cooperating with the observation window 14, it is convenient for personnel to observe the internal structure of the filling disk 31 for timely maintenance or correction.

[0032] Working principle of this embodiment: When in use, first install the fixed frame 1 to the target position and ensure stability, and its bottom upright pole 5 is vertically downward as the guide rail for installing the anti-sway plate 3, and then insert the outer assembly piece 6 of the filling plate 31 into the upright pole 5, slide it to the appropriate height below the suspension rod 2, adjust the upper and lower anti-sway plates 3 to be coaxial and perpendicular to the axis of the suspension rod 2, rotate the hand-tightening screw sleeve 7 to fix the assembly piece 6, and then fix the bottom connecting flange of the fastener 4 to the top flange of the bottom anti-sway plate 3 with bolts. During debugging, check the viscous oil, sealing ring 37 and In the reset spring 35 state, manually push the boom 2 to test the sliding of the anti-sway plate 32, the oil damping and the spring reset performance, and finally adjust the limit range of the fastener 4 according to the needs. When the boom 2 shakes or swings, its surface will contact the inner side of the anti-sway plate 32 of the anti-sway plate 3, and the anti-sway plate 32 will be displaced along the inner side of the filling plate 31 after being subjected to force. When the anti-sway plate 32 is displaced, it will push the oil to flow between the inner side of the filling plate 31 and the slider part 33, and it will also flow along the inner side of the flow hole 34 of the slider part 33 to block and buffer it.

[0033] Example 2: Based on Example 1, Figure 1-7 An anti-sway fastening device for a constant force support hanger further includes a fastener 4, wherein the fastener 4 includes a slide 41 and a main frame 42, the outer side of the main frame 42 is rotatably connected to six rotating sleeves 43, the inner side of the rotating sleeve 43 is rotatably connected to a fastening rod 44, the outer side of the slide 41 is slidably connected to an adjustment ring 45, the outer side of the adjustment ring 45 is rotatably connected to a side rod 46, and the side rod 46 is rotatably connected to the fastening rod 44 on a side away from the adjustment ring 45; By setting the slide 41 to cooperate with the main frame 42 and the rotating sleeve 43, if it is necessary to further limit the movable range of the boom 2, the fastening rod 44 can be rotated along the rotating sleeve 43 on the outside of the main frame 42. Multiple fastening rods 44 can limit the moving range of the boom 2 when approaching or moving away from the boom 2. When the boom 2 contacts the fastening rod 44, the main frame 42, the slide 41 and the blocking plate 32 connected thereto that are in contact with the fastening rod 44 will all be subjected to force, thereby triggering the buffering, anti-sway and reset effects of the anti-sway plate 3. By setting the adjustment ring 45, when the position of the fastening rod 44 needs to be adjusted, the adjustment ring 45 can be used to slide vertically along the slide 41 to synchronously push and pull the fastening rod 44 through the side rod 46, thereby achieving the effect of simultaneously moving multiple fastening rods 44 synchronously close to or away from the boom 2 of the vertical rod 5.

[0034] Among them, the bottom of the slide 41 is fixedly connected with an extension frame 8, the bottom of the extension frame 8 is fixedly connected to the connecting flange, the bottom of the outer side of the slide 41 is fixedly connected with a transmission sleeve 9, the inner side of the transmission sleeve 9 is threadedly connected with a screw rod 10, and the top of the screw rod 10 is rotatably connected to the adjustment ring 45. By setting the extension frame 8, it is used to extend the distance between the slide 41 and the bottom filling tray 31 to ensure that there is enough distance for the screw rod 10 to move. When the position of the adjustment ring 45 needs to be adjusted, the screw rod 10 can be rotated along the transmission sleeve 9, and the adjustment ring 45 connected thereto will move vertically along the slide 41 The top of the fastening rod 44 is rotatably connected to the connecting sleeve 11, and the side of the connecting sleeve 11 close to the boom 2 is fixedly connected to the fastening claw 12. The outside of the fastening claw 12 is provided with a contact pad. By setting the connecting sleeve 11 to cooperate with the fastening claw 12, the fastening claw 12 is used to directly contact the fastening rod 44 with the boom 2, thereby increasing the number of force points and the force area, and performing preliminary buffering through the contact pad to further reduce the damage caused by contact between the structures. The fastening claw 12 is set to an arc shape, and the contact pad is bonded to the side of the fastening claw 12 away from the connecting sleeve 11. The slide 41 is an annular The frame is welded with six cylindrical metal rods, and the inner side of the adjusting ring 45 is provided with a hole for use with the metal rod. By setting the arc-shaped fastening claws 12, more force points can be obtained compared with direct contact through the fastening rods 44, thereby reducing the probability that the boom 2 cannot be triggered when it swings between two adjacent fastening rods 44. The slide 41 welded by the annular frame and six cylindrical metal rods can limit the adjustment ring 45 when it is driven by the screw rod 10. The inner side of the connecting sleeve 11 is fixedly connected to the connecting torsion spring 13, which is close to the connecting torsion spring 13. One side of the fastening rod 44 is fixedly connected to the fastening rod 44. By setting a connecting torsion spring 13, when the connecting sleeve 11 and the fastening claw 12 contact the boom 2, the fastening claw 12 under force and the connecting sleeve 11 connected thereto will rotate and fit on the surface of the boom 2. When the fastening rod 44 directly contacts the boom 2, only a single point at the touching position contacts the boom 2, and the connecting sleeve 11 itself has a certain thickness, which changes the point contact into line contact and increases the contact area. At this time, the torsion spring accumulates force and rebounds after stopping contact to push the connecting sleeve 11 and the fastening claw 12 to reset.

[0035] The working principle of this embodiment is: when debugging the fastener 4, first rotate the screw 10, and through the threaded transmission of the transmission sleeve 9, the adjustment ring 45 is vertically lifted and lowered along the annular frame and the cylindrical metal rod of the slide 41. The adjustment ring 45 synchronously drives the six fastening rods 44 to rotate around the rotating sleeve 43 on the outside of the main frame 42 through the side rod 46, so that the arc-shaped fastening claw 12 on the top of the fastening rod 44 is synchronously close to or away from the boom 2 until the required boom 2 swing limit range is set. When the boom 2 swings and touches the fastening claw 12, the contact pad first buffers the impact, and then the fastening claw 12 is rotated to fit the surface of the boom 2 through the connecting torsion spring 13 in the connecting sleeve 11, converting the point contact into line contact to increase the force area, and at the same time triggering the damping buffer of the anti-sway plate 3 and the reset mechanism of the reset spring 35 to suppress the swing of the boom 2. When no limit is required, rotate the screw 10 in the opposite direction to make the fastening claw 12 away from the boom 2.

[0036] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed. Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
