Abstract
Description
Technical Field
[0001] This utility model belongs to the field of pipe gallery technology, and specifically relates to an anti-overturning protective pipe gallery. Background Technology
[0002] Existing petrochemical pipe racks and pipelines typically employ rigid structures for connection. While these structures can withstand weak blast shockwaves, maintaining stability and preventing damage, strong shockwaves can cause pipelines to fracture or overturn, disrupting chemical production and potentially triggering secondary explosions. Therefore, rigidly connected petrochemical pipelines in current technology cannot withstand strong blast shockwaves and are at risk of fracture and overturning. Utility Model Content
[0003] The purpose of this invention is to provide an anti-overturning protective pipe gallery to reduce the impact of explosion shock waves on petrochemical pipelines.
[0004] To achieve the above objectives, this utility model provides an anti-overturning protective pipe gallery, which includes: The pipeline body includes two straight pipe sections and a curved section connecting the two straight pipe sections, with both ends of the curved section slidably inserted into the two straight pipe sections respectively. The protective mechanism is located below the straight pipe section and can support the straight pipe section. The protective mechanism includes a limiting component and a failure switch installed on the limiting component. When the external impact force is less than the preset pressure, the failure switch locks the limiting component; when the external impact force is greater than the preset pressure, the failure switch unlocks the limiting component, so that the straight pipe section can move on the limiting component.
[0005] In an embodiment of this utility model, the limiting component further includes a track body and a limiting plate. The track body is connected to both ends along its length direction with limiting plates. The two limiting plates and the track body enclose a limiting space for limiting the straight pipe section. The straight pipe section is slidably disposed on the track body. The extension direction of the straight pipe section is perpendicular to the extension direction of the track body. The failure switch is disposed on the side of the track body facing the straight pipe section.
[0006] In an embodiment of this utility model, there are two failure switches arranged symmetrically about the center of the track body. The limiting component also includes a protective component and a pulley component. The protective component has an arc-shaped groove for supporting the straight pipe section. The pulley component is located on the side of the protective component away from the straight pipe section and between the two failure switches. The pulley component slides with the track body.
[0007] In an embodiment of this utility model, the track body is also provided with two limiting grooves corresponding to the failure switch. A fixed shaft is inserted into the inner wall of the limiting groove. The failure switch is rotatably mounted on the fixed shaft. The rotation of the failure switch relative to the fixed shaft can cause the failure switch to extend out of the limiting groove to limit the pulley, or the failure switch to retract into the limiting groove to release the pulley.
[0008] In an embodiment of this utility model, the protective mechanism further includes a torque adjusting component. The failure switch has a plug hole for the fixed shaft to be inserted into. The torque adjusting component is spirally wound around the outer peripheral wall of the fixed shaft. A first slot is formed on the inner peripheral wall of the plug hole, and a second slot is formed on the bottom surface of the limiting groove. The two ends of the torque adjusting component are respectively inserted into the first slot and the second slot.
[0009] In an embodiment of this utility model, the failure switch is further provided with a telescopic component, and a groove is provided on the inner wall of the limiting groove. The telescopic component can be inserted into and locked with the groove when the failure switch is in the unlocked state.
[0010] In an embodiment of this utility model, the protective mechanism further includes two guard plates, which are respectively disposed on both sides of the track body along the width direction. The top surface of the guard plate is lower than the bottom surface of the straight pipe section.
[0011] In an embodiment of this utility model, the curved section includes two straight pipe sections and a curved pipe section connecting the two straight pipe sections. The opposite ends of the two straight pipe sections are slidably inserted into different straight pipe sections. The length of the straight pipe section is greater than the distance between the side of the limiting plate facing the straight pipe section and the protective member.
[0012] In embodiments of this utility model, the protective mechanism further includes a flexible component connected between the straight pipe section and the limiting plate.
[0013] In embodiments of this utility model, there are multiple limiting members, which are arranged at intervals along the length of the straight pipe section.
[0014] Through the above technical solution, the anti-overturning protective pipe gallery provided by the embodiments of this utility model has the following beneficial effects: The anti-overturning protective pipe gallery in this application includes a pipe body and a protective mechanism. The pipe body includes straight pipe sections and curved sections connecting two straight pipe sections. Both ends of the curved section are slidably inserted into the two straight pipe sections, ensuring that when an external impact reaches the pipe body, the straight pipe sections can slide relative to the curved sections, mitigating the impact of external impact forces on the rigid pipe body in the prior art. Furthermore, the protective mechanism is located below the straight pipe sections and supports them. The protective mechanism includes a limiting member and a fail-safe switch mounted on the limiting member. When the external impact force is less than a preset pressure, the fail-safe switch locks the limiting member to prevent the straight pipe sections from sliding along it. When the external impact force is greater than the preset pressure, the fail-safe switch unlocks the limiting member, allowing the straight pipe sections to move on the limiting member. The limiting member restricts the range of movement of the straight pipe sections, mitigating the impact of external impact forces on the straight pipe sections and preventing the curved sections from tearing due to external impact forces.

[0017] Explanation of reference numerals in the attached figures Detailed Implementation
[0018] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.
[0019] The anti-overturning protection pipe according to the present invention is described below with reference to the accompanying drawings.
[0020] like Figure 1 and Figure 2 As shown, in this embodiment, an anti-overturning protective pipe gallery is proposed. The anti-overturning protective pipe gallery includes a pipe body and a protective mechanism. The pipe body includes a straight pipe section 11 and a curved section 12 connecting the two straight pipe sections 11. The two ends of the curved section 12 are slidably inserted into the two straight pipe sections 11, respectively, ensuring that when an external impact reaches the pipe body, the straight pipe section 11 can slide relative to the curved section 12, reducing the impact of external impact force on the rigid structure of the pipe body in the prior art. Furthermore, the protective mechanism is located below the straight pipe section 11 and can support the straight pipe section 11. The protective mechanism includes a limiting member 21 and a failure switch 22 disposed on the limiting member 21. When the external impact force is less than a preset pressure, the failure switch 22 can lock the limiting member 21 to prevent the straight pipe section 11 from sliding along the limiting member 21. When the external impact force exceeds the preset pressure, the failure switch 22 unlocks the limiting member 21, allowing the straight pipe section 11 to move on the limiting member 21. The limiting member 21 restricts the range of movement of the straight pipe section 11, reducing the impact of the external impact force on the straight pipe section 11 and preventing the bent section 12 from tearing due to the external impact force. It should be noted that the preset pressure can be adjusted according to actual needs.
[0021] like Figure 2 As shown, in this embodiment, the limiting member 21 also includes a track body 211 and a limiting plate 212. The track body 211 has limiting plates 212 connected to both ends along its length. The track body 211 and the limiting plates 212 can be manufactured using an integral molding process, which reduces production costs and installation steps of the limiting member 21. The two limiting plates 212 and the track body 211 enclose a limiting space for limiting the straight pipe section 11. The straight pipe section 11 is slidably mounted on the track body 211. When an external impact force acts on the straight pipe section 11, the straight pipe section 11 can slide along the length of the track body 211. The limiting plates 212 prevent the straight pipe section 11 from sliding too far, thus avoiding tearing the bent section 12, and also reduce the impact of external impact force on the straight pipe section 11, preventing structural damage to the straight pipe section 11. The extension direction of the straight pipe section 11 is perpendicular to the extension direction of the track body 211. The failure switch 22 is located on the side of the track body 211 facing the straight pipe section 11 to lock the straight pipe section 11 when the external impact force is less than the preset pressure, so as to prevent the straight pipe section 11 from sliding along the track body 211.
[0022] like Figure 2 and Figure 3 As shown, in this embodiment, there are two failure switches 22 arranged symmetrically about the center of the track body 211. The two failure switches 22 are spaced apart along the length of the track body 211, and the straight pipe section 11 is placed between the two failure switches 22, so that the distance between the straight pipe section 11 and the two limiting plates 212 is equal. Under the influence of external impact force, it can ensure that there is enough buffer distance for the straight pipe section 11 to slide. The limiting member 21 also includes a protective member 213 and a pulley member 214. The protective member 213 has an arc-shaped groove to support the straight pipe section 11, avoiding collision damage caused by direct contact between the straight pipe section 11 and the limiting plate 212 during the sliding of the straight pipe section 11 along the track body 211, and effectively protecting the straight pipe section 11. The pulley component 214 is located on the side of the protective component 213 away from the straight pipe section 11 and between the two fail-safe switches 22. The pulley component 214 slides in conjunction with the track body 211 to better convert the external impact force acting on the straight pipe section 11 into a sliding force, thereby reducing the impact of the external impact force on the straight pipe section 11 and preventing the curved section 12 from being torn by the external impact force. It should be noted that the inner wall of the arc-shaped groove is adapted to the shape of the outer peripheral wall of the straight pipe section 11 to ensure that the straight pipe section 11 can be stably placed in the arc-shaped groove. Preferably, the height of the top surface of the protective component 213 should be higher than the center of gravity height of the straight pipe section 11 to prevent the external impact force from knocking the straight pipe section 11 out of the arc-shaped groove.
[0023] like Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment, the track body 211 is also provided with two limiting grooves 216 corresponding to the failure switch 22. A fixed shaft 215 is inserted into the inner wall of the limiting groove 216. The extension direction of the fixed shaft 215 is consistent with the extension direction of the straight pipe section 11, and both are perpendicular to the track body 211. The failure switch 22 is rotatably mounted on the fixed shaft 215. The rotation of the failure switch 22 relative to the fixed shaft 215 can cause the failure switch 22 to extend out of the limiting groove 216 and limit the pulley 214, or the failure switch 22 to retract into the limiting groove 216 to release the pulley 214. Specifically, when the external impact force is less than the preset pressure, the failure switch 22 extends out of the limiting groove 216 to limit the pulley 214, preventing the straight pipe section 11 from sliding along the track body 211. When the external impact force exceeds the preset pressure, the failure switch 22 can mechanically rotate relative to the fixed shaft 215, causing the failure switch 22 to retract into the limiting groove 216, thus preventing interference with the sliding of the pulley component 214 along the track body 211. At this time, the straight pipe section 11 can slide along the track body 211, reducing the impact of the external impact force on the straight pipe section 11, and preventing the curved section 12 from being torn by the external impact force. Among them, the pulley component 214 is a pulley in the prior art.
[0024] like Figure 5 As shown, in this embodiment, the protective mechanism further includes a torque adjusting member 23. The fail switch 22 has a insertion hole for the fixed shaft 215 to be inserted into. The torque adjusting member 23 is spirally wound around the outer peripheral wall of the fixed shaft 215 and extends along the length of the fixed shaft 215. A first slot is formed on the inner peripheral wall of the insertion hole, and a second slot is formed on the bottom surface of the limiting groove 216. The two ends of the torque adjusting member 23 are respectively inserted into the first slot and the second slot. The torque adjusting member 23 uses a torque spring, as is common in the prior art. Because the torque spring itself has elastic restoring force, when the external impact force is less than the preset pressure, the elastic force of the torque spring can drive the fail switch 22 to extend out of the limiting groove 216, thereby stably limiting the pulley member 214 and preventing the pulley member 214 from sliding along the track body 211. Figure 6 As shown, preferably, in this embodiment of the application, two torque adjusting members 23 are provided. Both torque adjusting members 23 are spirally wound on the outer peripheral wall of the fixed shaft 215. The spiral winding directions of the two torque adjusting members 23 are opposite, so that the force is more uniform.
[0025] like Figure 4 and Figure 5 As shown, in this embodiment, the failure switch 22 is also provided with a telescopic groove for accommodating the telescopic member 221. A groove 217 is formed on the inner wall of the limiting groove 216, and the telescopic member 221 can be inserted and locked into the groove 217 when the failure switch 22 is in the unlocked state. The telescopic member 221 includes a telescopic block and an elastic member. The two ends of the elastic member are respectively connected to the telescopic block and the bottom of the telescopic groove. In the initial state, the elastic member is in a compressed state. When the failure switch 22 rotates around the fixed axis 215 and the telescopic block aligns with the groove 217, the elastic member will rebound. The elastic member drives the telescopic block to insert into the groove 217 to limit and lock the failure switch 22 and the track body 211, avoiding interference with the sliding of the pulley 214 along the track body 211. Furthermore, the failure switch 22 also has a limiting surface that contacts the pulley component 214. When the failure switch 22 is in the unlocked state and the telescopic block is inserted into the groove 217, it ensures that the limiting surface and the top surface of the track body 211 are at the same horizontal level to avoid affecting the sliding of the pulley component 214 along the track body 211. It should be noted that the telescopic block can be set to a cubic or cylindrical shape, as long as the shape of the telescopic block can be adapted to the groove 217 on the inner wall of the limiting groove 216, and the elastic element is a spring in the prior art.
[0026] In this embodiment, the protective mechanism also includes two guard plates (not shown in the drawings), which are respectively disposed on both sides of the track body 211 along the width direction. The top surface of the guard plate is lower than the bottom surface of the straight pipe section 11. By setting the guard plates to block the pulley component 214, the risk of the pulley component 214 falling off the track body 211 when sliding along the track body 211 can be effectively avoided, ensuring that the pulley component 214 can slide stably along the track body 211. Preferably, the distance between the top surface of the guard plate and the top surface of the track body 211 is greater than 1 / 5 of the diameter of the pulley component 214, so as to better prevent the pulley component 214 from falling off when sliding.
[0027] like Figure 2 and Figure 7 As shown, in this embodiment, the curved section 12 includes two straight pipe sections 121 and a curved pipe section 122 connecting the two straight pipe sections 121. The opposite ends of the two straight pipe sections 121 are slidably inserted into different straight pipe sections 11. The length of the straight pipe section 121 is greater than the distance between the side of the limiting plate 212 facing the straight pipe section 11 and the protective member 213, to prevent the straight pipe section 11 from detaching from the curved section 12. The length of the straight pipe section 121 is L2 in the figure. Furthermore, a sealing ring is provided between the straight pipe section 11 and the straight pipe section 121 to prevent the material inside the pipe body from escaping. When the straight pipe section 11 is pulled by an external impact force, it can slide back and forth along the length direction of the straight pipe section 121 to prevent the straight pipe section 11 and the curved section 12 from being damaged due to a large external impact force.
[0028] In this embodiment, the protective mechanism also includes a flexible component connecting the straight pipe section 11 and the limiting plate 212. Specifically, the flexible component can be made of materials such as polyurethane, aluminum foam, or springs. The flexible component can absorb energy through its own deformation to buffer the impact of external impact forces on the straight pipe section 11, thereby better protecting the pipe body.
[0029] like Figure 1 As shown, in this embodiment, the number of limiting members 21 is multiple and they are arranged at equal intervals along the length of the straight pipe section 11, which provides better support stability and can better protect the straight pipe section 11 from damage by external impacts. The number of limiting members 21 can be adjusted according to actual needs.
