This device not only can effectively inhibit the axial displacement of pipeline, but also allows to have a certain degree of freedom in the radial direction, thus plays an important role in adapting dynamic load, reducing pipeline vibration and noise. It has key significance in the safety and stability guarantee of pipeline system operation, and reasonable selection, design and installation are the basis to ensure its expected function.
[0003] At present, the standard mainly executed at home is 795 type structure in D-ZD2010 "power plant steam pipeline support and hanger design manual". Although this traditional design has certain maturity in practical application, but also has many problems. For example, the overall structure is relatively cumbersome, and the use of material is more, which not only increases the manufacturing cost, but also is not conducive to the optimization of installation space. At the same time, the welding work load is large in the manufacturing process of this kind of product, especially when special material is used, the price of welding material required is expensive, which further improves the manufacturing cost. In addition, heat treatment process is needed after welding, which leads to high energy consumption. More seriously, the production cycle of this kind of pipe clamp is long, which is not conducive to the construction progress of engineering project. In the running stage, when the pipeline produces angular displacement, the traditional structure is easy to cause uneven stress of two side hangers, and the stress of one side will increase significantly, which may cause structure fatigue or failure, and there is a great safety hazard. Therefore, the prior art needs to be improved in structure optimization, manufacturing efficiency and adaptive variable working condition capacity. UTILITY MODEL CONTENTS

[0018] The riser 1 axial position dynamic load tube clamp is provided with force bearing and installation support by the main body of hollow structure.The two parallel spaced apart load plates 2 inside the main body form stable support surface, which is used in cooperation with trunnion tube 3 to effectively transfer the axial load of riser 1 to the main body, thereby limiting the axial displacement of riser 1.Trunnion tube 3 is arranged on the tube body of riser 1 and is arranged along the radial direction to ensure that it is uniformly stressed and stably fixed between the load plates 2.The two load plates 2 clamp riser 1, which helps to prevent displacement or loosening of riser 1 when subjected to dynamic load impact.Connecting seat 6 is arranged at both ends of the main body and is connected to the steel beam through support rod 9 to form a rigid connection path from the main body of the tube clamp to the structural support member, thereby enhancing the stability of the system.
[0019] The structure realizes effective limiting of riser 1 under dynamic load working condition and improves the impact resistance and load bearing capacity of the device.The cooperation and connection of trunnion tube 3 and load plate 2 enhance the stability and anti-unbalanced load capacity of the overall structure.The hollow structure of the main body reduces the overall weight while ensuring strength, which is conducive to installation and maintenance.Support rod 9 is fixedly connected to the steel beam, which helps to reasonably distribute the load to the bearing structure, thereby improving safety and service life.In addition, the tube clamp structure is compact and suitable for installation in space-limited environments.
[0020] In a possible implementation, the surface of load plate 2 is provided with a connecting hole, and trunnion tube 3 is arranged in the connecting hole.
[0021] In the above implementation, the trunnion tube 3 can be arranged in the connecting hole of load plate 2, thereby stably positioning riser 1 between the load plates 2.Trunnion tube 3, as an intermediate component, is fixedly connected to riser 1 and passes through the connecting hole of load plate 2, so that the axial load of riser 1 can be directly transmitted to load plate 2 and then transmitted to the load plate 2 and the overall main body structure, forming a complete force transmission path.This structure can enhance the limiting effect of riser 1 between the load plates 2 and prevent riser 1 from loosening or deviating due to dynamic load.

[0024] In the above implementation, the limiting block 10 is arranged above the load plate 2 and closely attached to the pipe body of the riser 1. The limiting block 10 can limit the movement of the riser 1 in the vertical direction, and prevent the riser 1 from being dislocated between the load plates 2 due to the jumping or vibration caused by dynamic load. The limiting block 10 is usually made of rigid material and fixed to the structure part above the load plate 2. The structural position is accurately designed, so that it can play an additional displacement prevention role without interfering with the axial force transmission of the trunnion pipe 3.

The connecting plate 4 is distributed on both sides of the load plate 2, and the connecting seat 6 is arranged on the connecting plate 4.
[0027] In the above implementation, the upper and lower boundary structures of the main body are formed by the two beam plates 5. The multiple connecting plates 4 and the two load plates 2 are arranged between the beam plates 5 to form a stable three-dimensional frame. The connecting plate 4 is evenly distributed on both sides of the load plate 2 and fixedly connected to the beam plate 5 to form multiple stable support points.

The connecting seat 6 is installed on the connecting plate 4, and the connecting path between the entire pipe clamp system and the external structure is constructed through the connection of the connecting seat 6 with the support rod 9 and the steel beam, so as to ensure efficient load transmission and distribution.
[0028] The frame structure constructed by the double cross beams and the multiple connecting plates 4 has good structural strength and stability, improves the bearing performance and optimizes the load transmission path. The design significantly enhances the overall impact resistance and torsional stiffness, so that the structure still maintains the structural integrity under the multi-axial loading working condition. The integrated configuration of the connecting seat 6 and the connecting plate 4 simplifies the manufacturing and assembly process, and improves the modularity and maintenance convenience.
[0029] In a possible implementation, the connecting seat 6 includes a bottom plate 7 and at least two vertical plates 8. The bottom plate 7 is fixed on the upper side of the connecting plate 4.

The vertical plates 8 are vertically arranged on the bottom plate 7 and are provided with through holes on the surface for the supporting rods 9 to pass through. The supporting rods 9 pass through the connecting seat 6 through the through holes and are connected with the steel beams to form a stable stress channel. The clamping structure between the vertical plates 8 and the cooperation with the supporting rods 9 enable the supporting force to be evenly distributed to the connecting plate 4 and the main frame, thereby effectively transferring the external load.
[0031] The connecting seat 6 has a reasonable structure design, is convenient for rigid connection with the supporting rods 9, and improves the connection stability and load bearing capacity. The through hole structure simplifies the installation mode of the supporting rods 9, and improves the ability of the structure to resist transverse load and bending moment.
