Description

Technical Field

[0001] This utility model relates to the field of venting riser technology, and in particular to a venting riser tension rope clamp, tension rope replacement device and support system. Background Technology

[0002] In gas well stations, the vent stack (or flame stack) is a critical facility for the safe discharge of natural gas, exhaust gas, or emergency pressure relief. It typically reaches a height of about 15 meters. To ensure the vent stack remains stable and upright, tension ropes are usually used to secure it. For example, the vent stack is usually equipped with connecting lugs; the upper end of the tension rope is connected to the connecting lugs, and the lower end is fixed to the ground. Three tension ropes can be used to pull the vent stack from three directions to maintain its stability. However, the tension ropes are easily corroded by long-term exposure to the natural environment. Vibration and displacement of the riser during venting also wear down the ropes. Over time, some tension ropes may break, which will seriously affect the stability of the riser, necessitating replacement.

[0003] Currently, the replacement solutions for the vent riser cable include: ① Erecting scaffolding, with workers manually replacing the cable at height. This method has a wide range of applications, but the process of erecting and dismantling the scaffolding is cumbersome, the construction cost is high, the efficiency is low, and there are significant safety risks associated with working at height; ② Using a lifting platform to lift workers and the new cable to a height. Although this method can effectively reduce the difficulty of working at height, it is only suitable for sites with convenient transportation and open, flat terrain. After the installation of the vent riser at a natural gas station is completed, some farmland needs to be restored, and the site is basically located in farmland. Due to the limitations of the terrain, it is difficult to place the equipment there.

[0004] All of the above solutions have high economic costs and certain limitations. In particular, in the hazardous chemical industry, when dealing with emergencies or emergency repairs, the above solutions are difficult to meet the on-site requirements. Utility Model Content

[0005] The purpose of this utility model is to overcome the problems of high cost and great limitations of existing rope replacement schemes in the background art, and to provide a rope clamp for venting risers, a rope replacement device and a support system.

[0006] In a first aspect, this utility model provides a venting riser rope clamp, comprising: A sleeve with a through channel inside, and a notch for limiting the sleeve at the first end; A connecting portion is provided on the outer wall of the sleeve, and at least three connecting portions are provided along the circumference of the sleeve. The connecting portions are used to connect the tension rope. The hoisting structure is located at the second end of the sleeve.

[0007] The vent riser tension rope clamp of this utility model is used by connecting the tension rope to the connecting part on the sleeve, then using a tool to lift the sleeve to the upper end of the vent riser, and then moving the sleeve so that the upper end of the vent riser passes through the through channel of the sleeve. The sleeve slides down the vent riser to a certain limit point (for example, at the original connecting ear plate on the vent riser) and stops sliding down. At this time, since at least three connecting parts are arranged around the circumference of the sleeve, different tension ropes can be pulled in different directions on the ground to constrain the sleeve, thereby constraining the vent riser passing through the sleeve. By setting a notch in the groove at one end of the sleeve, the relative rotation of the sleeve with respect to the vent riser is restricted, thereby restricting the torsion of the vent riser and reducing the probability of torsion damage to the vent riser.

[0008] The venting riser rope clamp described in this utility model does not require the erection of scaffolding or the use of a lifting platform, and does not require workers to work at heights. It can conveniently and quickly complete the rope replacement, and the cost is low.

[0009] Preferably, the sleeve is a cylinder, and the depth direction of the notch in the slot is parallel to the axis of the sleeve.

[0010] Preferably, at least three of the notches are provided along the circumference of the sleeve, and the notches correspond to the connecting portion.

[0011] Preferably, the connecting part includes a first connecting plate, which protrudes from the outer wall of the sleeve, and the first connecting plate is provided with a connecting hole.

[0012] Preferably, the sleeve, the first connecting plate, and the hoisting structure are all steel components.

[0013] Preferably, the hoisting structure is used to connect the hoisting rope.

[0014] Preferably, the hoisting structure includes two hooks, which are symmetrically distributed on both sides of the sleeve.

[0015] Preferably, the hook includes a hook shank and a hook head connected together, the end of the hook shank away from the hook head is connected to the sleeve, and the hook head protrudes from the second end of the sleeve.

[0016] Preferably, the hook shank is connected to the outer wall of the sleeve.

[0017] In a second aspect, this utility model provides a venting riser rope replacement device, including the venting riser rope clamp as described above, and further comprising: The first tension rope has one end connected to the connecting part, and at least three first tension ropes are arranged along the circumference of the sleeve. Drones are capable of flight; A hoisting rope connects the drone to the hoisting structure; The drone is capable of lifting the sleeve and positioning the first end of the sleeve downwards.

[0018] In a third aspect, this utility model provides a venting riser support system, including a venting riser, the side wall of which is provided with a second connecting plate, and also includes a first tension rope and a venting riser tension rope sleeve as described above. The sleeve is fitted onto the venting riser, and at least one of the second connecting plates is embedded in the slot notch; the upper end of the first tension rope is connected to the connecting part, and the lower end is fixed to the ground.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: The vent riser tension rope clamp of this utility model is used by connecting the tension rope to the connecting part on the sleeve, then using a tool to lift the sleeve to the upper end of the vent riser. The sleeve is then moved so that the upper end of the vent riser passes through the through-channel of the sleeve. The sleeve slides down the vent riser to a certain limit point (e.g., at the original connecting lug on the vent riser) and stops sliding. At this point, since at least three connecting parts are arranged circumferentially along the sleeve, different tension ropes can be pulled in different directions on the ground to constrain the sleeve, thereby constraining the vent riser passing through the sleeve. By setting a notch at one end of the sleeve, the relative rotation of the sleeve with respect to the vent riser is restricted, thereby limiting the torsion of the vent riser and reducing the probability of torsional damage. The vent riser tension rope clamp of this utility model does not require scaffolding or a lifting platform, eliminates the need for workers to work at heights, allows for convenient and quick tension rope replacement, and has a low cost.

[0028] Example like Figures 1 to 4 As shown, in a first aspect, this application provides a venting riser rope clamp, including a sleeve 1, the sleeve 1 having a through channel formed inside, through channel for the venting riser 4 to pass through, and a connecting part 2 provided on the outer wall of the sleeve 1 for connecting the rope.

[0029] A tension rope is a rope used for fixing, binding or supporting. The material of the tension rope is not limited and can be steel wire rope, nylon rope, etc. One end of the tension rope can be connected to the connecting part 2 on the ground. Then, by lifting the sleeve 1, the sleeve 1 is put into the venting riser 4 from the upper end of the venting riser 4. Then, by pulling the other end of the tension rope, the sleeve 1 and the venting riser 4 are constrained.

[0030] In some embodiments, the sleeve 1 has a cylindrical structure with two opposing openings in its internal through-channel. The venting riser 4 can be inserted through one opening and exited through the other opening, so that the sleeve 1 can be fitted onto the venting riser 4.

[0031] In some embodiments, the sleeve 1 is provided with a lifting structure 3, which is used to connect a lifting rope 51. The other end of the lifting rope 51 can be connected to a hoisting device, so that the sleeve 1 can be lifted by the hoisting device.

[0032] Preferably, the hoisting equipment is a drone 5. A drone 5 is an aircraft that can be remotely controlled or fly autonomously. It usually includes a rotor and a fuselage. The rotation of the rotor can give the drone 5 an upward lift, enabling it to fly off the ground. The fuselage of the drone 5 and the hoisting structure 3 are connected by a hoisting rope 51. The sleeve 1 can be raised by the drone 5 until the lower opening of the sleeve 1 is higher than the upper end of the venting riser 4. After aligning the lower opening of the sleeve 1 with the venting riser 4, the drone 5 can be lowered so that the sleeve 1 is fitted onto the venting riser 4.

[0033] The upper and lower openings of sleeve 1 are the two opposite openings of the through channel mentioned above. The upper opening refers to the opening located at the top during hoisting, and the lower opening refers to the opening located at the bottom during hoisting.

[0034] In some embodiments, at least three connecting parts 2 are arranged circumferentially along the sleeve 1, and each connecting part 2 can be connected to a tension rope, so that multiple tension ropes can be connected to different positions of the sleeve 1. By pulling different tension ropes in different directions, forces in different directions can be applied to the sleeve 1, thereby restricting the horizontal displacement of the sleeve 1. Since the venting riser 4 passes through the sleeve 1, the horizontal displacement of the venting riser 4 can also be restricted, preventing the venting riser 4 from tipping over, thus achieving the effect of restraining the venting riser 4. By reducing the inner diameter of the sleeve 1 to be close to the outer diameter of the venting riser 4, the range of motion of the venting riser 4 can be further reduced until the venting riser 4 is fixed.

[0035] In some embodiments, one end of the sleeve 1 is provided with a notch 11, such as Figures 1 to 3 As shown, the notch 11 can be formed by cutting the side wall of the sleeve 1. The part near the end of the sleeve 1 is open, allowing other components to enter the notch 11 along the axial direction of the sleeve 1. Other components include plates, rods, etc. The notch 11 includes a bottom surface and two opposite sides. The sides can restrict the movement of other components embedded in the notch 11 along the circumferential direction of the sleeve 1. It can be understood that the venting riser 4 is usually provided with a protruding connecting ear plate 8, which is used to connect with the original tension rope. The notch 11 is provided on the sleeve 1. The notch 11 can be fitted with the original connecting ear plate 8 on the venting riser 4 to restrict the relative rotation of the sleeve 1 and the venting riser 4, thereby restricting the torsion of the venting riser 4 and reducing the probability of torsion damage to the venting riser 4.

[0036] The notch 11 of the slot is set to correspond to the connecting ear plate 8 on the venting riser 4. In the example, the venting riser 4 is provided with three connecting ear plates 8. Three notches 11 can be opened on the sleeve 1 to fit and cooperate with the three connecting ear plates 8.

[0037] In some embodiments, the sleeve 1 has a first end 12 and a second end 13 distributed along its axis. A notch 11 is provided at the first end 12 of the sleeve 1, and a lifting structure 3 is provided at the second end 13 of the sleeve 1. When the sleeve 1 is lifted, the first end 12 of the sleeve 1 corresponds to the lower cylinder opening mentioned above, and the second end 13 of the sleeve 1 corresponds to the upper cylinder opening mentioned above. That is, the end with the notch 11 is first inserted into the venting riser 4, and the connecting ear plate 8 on the venting riser 4 can be fitted with the notch 11.

[0038] Preferably, the inner diameter of the sleeve 1 is larger than the outer diameter of the venting riser 4, so that the sleeve 1 can be fitted into the venting riser 4 and slide along the venting riser 4; further, the inner diameter of the sleeve 1 is smaller than the outer contour of the connecting ear plate 8 on the venting riser 4, so that the sleeve 1 slides to the connecting ear plate 8 and then stops sliding down, so that the sleeve 1 and the tension rope can constrain the upper part of the venting riser 4.

[0039] The venting riser tension rope clamp described in this embodiment allows the tension rope and lifting rope 51 to be connected to the connecting part 2 and the lifting structure 3 on the sleeve 1 respectively on the ground. Then, by pulling the lifting rope 51, the sleeve 1 is raised to be higher than the upper end of the venting riser 4. The sleeve 1 is then moved so that the upper end of the venting riser 4 passes through the through channel of the sleeve 1. The sleeve 1 slides down along the venting riser 4 to the original connecting ear plate 8 and stops sliding. At this time, different tension ropes can be pulled in different directions on the ground to constrain the sleeve 1, thereby constraining the venting riser 4 that passes through the sleeve 1. By setting a notch 11 at one end of the sleeve 1, the notch 11 can be fitted with the original connecting ear plate 8 on the venting riser 4 to restrict the relative rotation of the sleeve 1 and the venting riser 4, thereby restricting the torsion of the venting riser 4 and reducing the probability of torsion damage to the venting riser 4. The venting riser rope clamp described in this embodiment does not require scaffolding or a lifting platform, eliminating the need for workers to operate at heights. It allows for convenient and quick rope replacement at a low cost.

[0040] In some embodiments, the depth direction of the notch 11 is parallel to the axis of the sleeve 1. The depth direction of the notch 11 refers to the direction from the notch 11 towards the opening of the first end 12 of the sleeve 1 to the bottom surface of the notch 11. It can be understood that the connecting lug 8 on the venting riser 4 is usually a plate parallel to the venting riser 4. After the sleeve 1 is fitted into the venting riser 4, its axis is approximately parallel to the venting riser 4. Making the depth direction of the notch 11 parallel to the axis of the sleeve 1 allows the connecting lug 8 to extend into the notch 11 more smoothly, so that the two can be better constrained and fitted together.

[0041] In some implementations, such as Figures 1 to 4 As shown, at least three notches 11 are arranged around the sleeve 1, and the notches 11 are corresponding to the connecting parts 2. That is, the notches 11 and the connecting parts 2 are arranged at the same position around the sleeve 1. This allows the first tension rope 6 connecting the sleeve 1 and the second tension rope 7 (that is, the original tension rope) connecting the connecting ear plate 8 to be distributed in the same position, which makes it convenient to use the existing fixing device on the ground to fix the first tension rope 6.

[0042] In some embodiments, the connecting part 2 includes a first connecting plate 21, which protrudes from the outer wall of the sleeve 1. The first connecting plate 21 is provided with a connecting hole 22. The end of the first tension rope 6 can pass through the connecting hole 22 and then be folded back and tied to the part that does not pass through the connecting hole 22, thereby fixing the first tension rope 6 to the first connecting plate 21.

[0043] In some embodiments, the sleeve 1, the first connecting plate 21, and the lifting structure 3 are all steel components, and the sleeve 1, the first connecting plate 21, and the lifting structure 3 can be welded together.

[0044] In some embodiments, the lifting structure 3 includes at least two hooks 31, and a lifting rope 51 can be fitted onto the hooks 31.

[0045] In some embodiments, the lifting structure 3 further includes two hooks 31 symmetrically distributed on both sides of the sleeve 1, two lifting ropes 51 connected to the two hooks 31 respectively, and the lifting equipment, such as a drone 5, connected to the other end of the lifting rope 51, or the two ends of the same lifting rope 51 are connected to the two hooks 31 respectively, and the lifting equipment, such as a drone 5, is connected to the middle of the lifting rope 51.

[0046] In some implementations, further, such as Figure 2 As shown, the hook 31 includes a hook shank 32 and a hook head 33 connected to each other. The hook head 33 is hook-shaped and its opening faces the first end 12 of the sleeve 1. The end of the hook shank 32 away from the hook head 33 is connected to the sleeve 1, and the hook head 33 protrudes from the second end 13 of the sleeve 1.

[0047] In some embodiments, the end of the lifting rope 51 is further connected to a lifting ring 52, which is fitted onto the hook 31. The lifting ring 52 facilitates the detachment of the lifting rope 51 from the hook 31 in the air.

[0048] In some embodiments, the hook handle 32 is connected to the outer wall of the sleeve 1, which can prevent the hook handle 32 from occupying the space of the through channel and make it convenient to put the sleeve 1 into the venting riser 4.

[0049] like Figure 5 and Figure 6 As shown, in a second aspect, this application provides a venting riser rope replacement device, including the venting riser rope clamp as described above, as well as a first rope 6 and a drone 5. One end of the first rope 6 is connected to the connecting part 2, and at least three first ropes 6 are arranged circumferentially along the sleeve 1. The drone 5 is connected to the hoisting structure 3 through a hoisting rope 51, and the drone 5 can lift the sleeve 1 and make the first end 12 of the sleeve 1 face downward.

[0050] The vent riser rope replacement device described in this embodiment is simple to operate, safe and reliable, and highly adaptable. The drone 5 assists in replacing the vent riser rope, which significantly improves the rope replacement efficiency and effectively avoids the safety risks associated with lifting or high-altitude operations. It reduces manpower input, lowers construction costs and labor intensity, and provides strong support for the efficient and safe operation of the vent riser 4. It is suitable for widespread application in the industry.

[0051] In some implementations, the length of the suspending rope 51 between the drone 5 and the sleeve 1 is greater than the distance from the upper end of the venting riser 4 to the connecting ear plate 8. After the lower opening of the sleeve 1 is aligned with the upper end of the venting riser 4, the drone 5 only needs to descend to make the sleeve 1 slide to the designated position, which can reduce the difficulty of operation.

[0052] In a third aspect, this application provides a venting riser support system, including a venting riser 4, the side wall of which is provided with a second connecting plate, namely the connecting ear plate 8 mentioned above; it also includes a first tension rope 6 and a venting riser tension rope sleeve as described above, the sleeve 1 is sleeved on the venting riser 4, and at least one second connecting plate is embedded in the slot notch 11; the upper end of the first tension rope 6 is connected to the connecting part 2, and the lower end is fixed to the ground.

[0053] The unbroken second tension rope 7 can be cut off after the sleeve 1 and the first tension rope 6 are installed, or it can be left uncut.

[0054] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
