Problems solved by technology

[0003] As a marginal oilfield development technology, FPSO needs to be relocated frequently. When the platform is relocated, the spring hanger needs to be locked with a positioning block. At this time, it is rigidly connected. It can only be opened after the inspection and experiment are completed after arriving at the position. This During the stage, the spring support hanger is in a rigid state, and there is an increased instantaneous load in

Embodiment 1

[0023] see Figure 1-2 , an automatic adjustment type constant force spring support and hanger, including a shell 1, a load bearing plate 2 and a support spring 3, the inside of the shell 1 is provided with a load bearing plate 2, and the upper end of the load bearing plate 2 passes through the upper connecting rod and the tube shoe Bolt connection, the lower end of the load-bearing plate 2 is provided with a support spring 3, the lower end of the support spring 3 is fixedly connected with a mobile load-bearing plate 5, the lower end of the load-bearing plate 2 is fixedly connected with a connecting rod 4, and the lower end of the connecting rod 4 is provided with a limit plate 6, The limit plate 6 and the mobile bearing plate 5 are movably connected in the vertical direction, and the load bearing plate 2 can move upward for a certain distance to drive the mobile bearing plate 5 to move, so that the mobile bearing plate 5 can move along with the upward movement of the pipeline....

Embodiment 2

[0026] refer to Figure 3-5 , the difference from Embodiment 1 is that the pressure balance structure includes traveling wheels 12 and rotating plates 13, the inner wall of the housing 1 is provided with rotating plates 13 arranged at equal intervals along the axial direction, and the movable bearing plate 5 is provided with retractable The walking wheels 12, the diameters of the two walking wheels 12 are smaller than the diameter of the walking wheels 12, the walking wheels 12 realize expansion and contraction through the spring with high elastic stiffness, under the action of the load, the walking wheels 12 press against the rotating plate 13, and the vertical The load is converted into the elastic force of the inner spring of the traveling wheel 12 and the force between the rotating plate 13 to support the pipeline. A limit block is set on the side of the rotating plate 13 away from the inner wall of the housing 1 to keep the rotating plate 13 horizontal. When the side of t...

Abstract

The invention relates to the technical field of marine engineering, and discloses an automatically-adjustable constant-force spring support and hanger. The automatically-adjustable constant-force spring support and hanger comprises a shell, a load-bearing plate and a supporting spring, and the shell sleeves the load-bearing plate. The supporting spring is arranged at the lower end of the load-bearing plate. According to the automatically-adjustable constant-force spring support and hanger, during use, the compression amount of the supporting spring is automatically adjusted as the magnitude ofthe load changes, and the supporting force is always kept within the design range; secondly, when a platform is moved, the maximum load is adjusted to the maximum to enable the spring support and hanger to be approximate to the rigid connection, if an excessive transient load occurs suddenly during the movement, the rigid connection becomes elastic connection to buffer the spring support and hanger, the support and hanger and a pipeline are protected, because the spring support and hanger can be automatically adjusted, and during the on-site adjustment, only a jack is required to adjust the height or angle; and meanwhile, the automatically adjusted parts are not corroded due to the movement, and debugging and assembly are relatively simple.

Description

technical field [0001] The invention relates to the technical field of marine engineering, in particular to an automatic adjustment type constant force spring support and hanger. Background technique [0002] In the design of the compressor gas pipeline of the FPSO project, especially the pipeline with high temperature and pressure and large vibration, the use of spring support and hanger can solve the support of the support, buffer the load and reduce the local stress. The stress on the flange at the nozzle can be well adjusted, so that the local load does not increase and the sealing of the pipeline will not be damaged. [0003] As a marginal oilfield development technology, FPSO needs to be relocated frequently. When the platform is relocated, the spring hanger needs to be locked with a positioning block. At this time, it is rigidly connected. It can only be opened after the inspection and experiment are completed after reaching the position. This During the stage, the s...
