Description

Technical Field

[0001] The utility model relates to the technical field of pipeline seismic resistance, in particular to a seismic resistance component for pipelines installed in steel structure trusses, especially a seismic resistance component for pipelines in steel structure trusses. Background Art

[0002] Pipes inside steel structure trusses usually refer to the pipeline structure installed inside the steel structure trusses. Currently, when installing pipes inside steel structure trusses, clamp-type pipe clamps are usually used to connect them with the load-bearing rods or components.

[0003] When the span of the pipeline in the steel structure truss is large, the pipeline support generally cannot rely solely on the support of beams and columns. It is necessary to add support hanging points between the columns, beams and purlins to ensure the stability and safety of the pipeline structure.

[0004] Although simply relying on support hanging point connection reinforcement can solve the problem of reinforcing pipes in steel structure trusses under large span conditions, its buffering effect is poor when dealing with vibration or wind loads. Therefore, its overall service life will be greatly affected when used under the above conditions for a long time. Therefore, buffer structures are often configured on the pipes in steel structure trusses.

[0005] For example, in the patent document with patent publication number CN217402059U, a pipeline shock-absorbing spring is disclosed, whose main structure includes a shell, in which a shock-absorbing spring is slidably installed, and a disassembly device for facilitating replacement is provided on the shock-absorbing spring, and the disassembly device includes a hook mechanism, a limiting mechanism and a movable mechanism, the hook mechanism includes a vertical rod and a disc, one end of the vertical rod is fixed to the disc, and a through hole is provided on the surface of the vertical rod, the limiting mechanism includes a U-shaped block and a bolt, the U-shaped block passes through the vertical rod and is slidably installed in the vertical rod, the U-shaped block is threadedly connected to the bolt, the bolt passes through the vertical rod and is threadedly connected to the vertical rod, and the movable mechanism includes a sliding rod, a bracket, a T-shaped movable block and a spring.

[0006] It can be seen from the records of the above-mentioned patent documents that the main purpose of the designed pipe shock-absorbing spring is to facilitate quick disassembly. In addition, since the built-in pipes of the steel structure truss under outdoor erection conditions will vibrate along with the vibration of the steel structure truss, the seismic measures under this condition play an important role in the safe operation of the pipeline; while the structure in the prior art only relies on the sliding shock-absorbing spring to achieve the buffering effect during actual use, which has a poor shock-absorbing effect when used under multi-directional load vibration loads.

[0007] To this end, the utility model optimizes and improves the problems existing in the seismic resistance of pipelines in the existing technology, and specially proposes a structure that is installed inside the steel structure truss and performs multi-directional support, buffering and shock absorption on the internal pipelines, so as to better solve the problems existing in the existing technology.

[0028] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the present invention's technical solution and are therefore only examples and are not intended to limit the scope of protection of the present invention. Figure 1-Figure 2 As shown in .

[0029] Embodiment: A seismic-resistant assembly for pipes within a steel structure truss comprises a pipe 2 installed within a space 3 within a steel structure truss 1. At least one seismic-resistant unit is installed along the outer wall of the pipe 2 along its length. The seismic-resistant unit comprises a plurality of lateral buffer mechanisms spaced apart on the circumferential outer wall of the pipe 2. The inner end of each lateral buffer mechanism abuts against the outer wall of the pipe 2, and the outer end of each lateral buffer mechanism is movably hinged to a welded lug 4 within the steel structure truss 1 at a corresponding position. An upper buffer attachment is installed between two upper lateral buffer mechanisms, and a lower buffer attachment is installed between two lower lateral buffer mechanisms. When this assembly provides seismic protection for the pipe 2, the number of seismic-resistant units to be installed at intervals is selected based on the current length of the pipe 2. Each seismic-resistant unit has the same structure and the spacing between them is determined based on the actual material and size of the pipe 2. The coordination of multiple seismic-resistant units achieves the purpose of quickly, effectively, and stably supporting the entire pipe 2 within the steel structure truss 1, thereby achieving multi-directional shock absorption.

[0030] In any of the above schemes, it is preferred that the lateral buffering mechanism includes a shock absorber 5 arranged on the outer side of the pipe 2 along the radial direction thereof, and an end ear seat 6 is fixedly installed on the outer end of the shock absorber 5, and the end ear seat 6 is movably connected to the welding ear seat 4 at the corresponding position, and a connecting shaft 7 is fixedly installed on the inner end of the shock absorber 5, and an arc seat 8 is fixedly installed on the inner end of the connecting shaft 7, and the inner side wall of the arc seat 8 abuts against the outer side wall of the pipe 2.

[0031] It should be noted that: when the lateral buffering mechanism performs lateral buffering, the arc-shaped seat 8 on the shock absorber 5 at the corresponding position is used to tighten the outer wall of the pipe 2. At the same time, since there are multiple lateral buffering mechanisms on the circumference of the pipe 2, the circumference of the pipe 2 can be mutually constrained. In addition, since the outer end of the shock absorber 5 of a single lateral buffering mechanism is in a hinged manner, the entire shock absorber 5 can also achieve a certain offset within a small range. In the offset state, the corresponding upper buffering accessories, lower buffering accessories and elastic rope 16 are used to complete the buffering constraint, thereby ensuring that the entire pipe 2 can be stably adjusted and supported when it is clamped and positioned.

[0032] After the pipe 2 is installed, its gravity will compress the two shock absorbers 5 at the bottom. Under the action of the two shock absorbers 5 at the bottom, the lower horizontal seat 12 and the lower triangular ring 14 complete the support positioning, effectively ensuring the bottom support effect of the pipe 2.

[0033] In any of the above schemes, it is preferred that a buffer spring 9 is sleeved on the outer wall of each connecting shaft 7, one end of the buffer spring 9 is fixed to the corresponding end of the shock absorber 5, and the other end of the shock absorber 5 is fixed to the outer wall of the arc seat 8.

[0034] Each buffer spring 9 can cooperate with the corresponding shock absorber 5 to play a buffering role, effectively increasing the use effect of the shock absorber 5.

[0035] In any of the above solutions, it is preferred that the center of each of the arc-shaped seats 8 is collinear with the central axis of the pipeline 2 .

[0036] The arc-shaped seat 8 is colinear with the center line of the pipeline 2 to ensure that the inner wall thereof and the outer wall of the pipeline 2 are tightly fitted when the arc-shaped seat 8 supports the pipeline 2 .

[0037] In any of the above schemes, it is preferred that the upper buffer accessory includes a horizontally arranged upper horizontal seat 10, both ends of the upper horizontal seat 10 are movably hinged to the connecting ear seat 11 fixedly connected to the arc seat 8 at the corresponding position, and the bottom of the upper horizontal seat 10 is arranged toward the top of the pipe 2.

[0038] In any of the above schemes, it is preferred that the lower buffer accessory includes a horizontally arranged lower horizontal seat 12, both ends of the lower horizontal seat 12 are movably hinged to the connecting ear seat 11 fixedly connected to the arc seat 8 at the corresponding position, and the top of the lower horizontal seat 12 is arranged toward the bottom of the pipe 2.

[0039] The upper horizontal seat 10 installed by the upper buffer accessory cooperates with the arc-shaped seats 8 at both ends to reinforce them, ensuring the linkage effect of the arc-shaped seats 8 on both sides when supporting; similarly, the lower horizontal seat 12 installed by the lower buffer accessory cooperates with the arc-shaped seats 8 at both ends to reinforce them, ensuring the linkage effect of the arc-shaped seats 8 on both sides when supporting.

[0040] In any of the above schemes, preferably, two upper triangular rings 13 are symmetrically fixedly spaced at the top of each upper horizontal seat 10 along its length direction; and two lower triangular rings 14 are symmetrically fixedly spaced at the bottom of each lower horizontal seat 12 along its length direction.

[0041] The lower triangular ring 14 can play the role of bottom support for the current pipeline 2 and transfer the load caused by the gravity of the pipeline 2 to the steel structure truss 1.

[0042] In any of the above solutions, preferably, the angle between the central axis of each shock absorber 5 and the horizontal line is ±45° or ±135°.

[0043] It should be noted that: by designing the angle to be ±45° or ±135°, the cooperation of the four shock absorbers 5 can better ensure the stability of the entire pipeline 2 when supporting it, and effectively ensure that the load is divided vertically and horizontally when supporting the pipeline 2. At the same time, the 45-degree angle can ensure the uniformity of the force distribution as much as possible.

[0044] In any of the above solutions, it is preferred that the shock absorber 5 is a double-acting cylinder shock absorber, which can achieve a better shock absorption effect during shock absorption.

[0045] In any of the above solutions, preferably, a rubber anti-slip pad 15 is fixedly mounted on the inner side wall of the arc-shaped seat 8 .

[0046] When the rubber anti-slip pad 15 abuts against the outer side wall of the corresponding pipe 2, it can effectively play a protective role and ensure stability when it is tightly positioned.

[0047] In any of the above schemes, it is preferred that a vertically arranged elastic rope 16 is installed between the two shock absorbers 5 spaced apart from top to bottom, and the two ends of the elastic rope 16 are respectively fixedly mounted on the shell of the shock absorber 5 at corresponding positions; the spacing distance between the elastic rope 16 and the outer wall of the pipe 2 is 3cm-5cm.

[0048] When the pipeline 2 is displaced laterally under the action of a load, the restraint and limitation of the elastic rope 16 on the corresponding side can play a role of lateral buffering.

[0049] Specific working principle: When the seismic protection of the pipe 2 installed inside the steel structure truss is performed by the seismic component designed in the present invention, it is necessary to select the number of seismic units to be installed at intervals according to the current length of the pipe 2. The structures of the seismic units are the same and the distance between them is determined according to the material and size of the actual pipe 2.

[0050] The cooperation of multiple seismic units can achieve the purpose of quickly, effectively and stably supporting the entire pipeline 2 inside the steel structure truss 1, thereby achieving the purpose of multi-directional shock absorption; specifically, during shock absorption, the arc-shaped seat 8 on the shock absorber 5 at the corresponding position is used to achieve the tightening of the outer wall of the pipeline 2. At the same time, due to the presence of multiple lateral buffer mechanisms on the circumference of the pipeline 2, the circumference of the pipeline 2 can be mutually constrained; in addition, since the outer end of the shock absorber 5 of a single lateral buffer mechanism is in a hinged manner, the entire shock absorber 5 can also achieve a certain offset within a small range. In the offset state, the corresponding upper buffer attachment, lower buffer attachment and elastic rope 16 are used to complete the buffer constraint, thereby ensuring that the entire pipeline 2 can be stably adjusted and supported when it is clamped and positioned.

[0051] From the above, it can be seen that the components of the present invention can be installed in the space of the existing steel structure truss 1 to provide circumferential support and earthquake resistance for the internal pipe 2, and can effectively cope with multi-directional vibrations under complex loads and effectively achieve multi-directional shock absorption. The cooperation of each lateral buffer mechanism can effectively ensure the lateral tight positioning of the pipe 2. After positioning, when the pipe 2 is subjected to a load in a certain direction, the corresponding multiple lateral buffer mechanisms will cooperate with each other to achieve effective position limiting and shock absorption, thereby comprehensively improving the buffering and shock absorption effects. When the pipe 2 is subjected to a large vertical load, the upper buffer attachment located at the top and the lower buffer attachment located at the bottom can cooperate with each lateral buffer mechanism to play the role of a vertical secondary buffer. When the pipe 2 is subjected to a large horizontal load, the elastic ropes 16 located on both sides can effectively play the role of a lateral buffer support, effectively playing the role of a horizontal secondary buffer and protection.
