Description

TECHNICAL FIELD

[0001] The utility model belongs to pipeline installation field, concretely relates to an adjustable support for petroleum pipeline installation. BACKGROUND

[0002] In the field of petroleum pipeline construction, the support is a key component for supporting and fixing the pipeline, and its structural stability and adjustment capacity directly affect the construction efficiency and the reliability of long-term operation of the pipeline. The traditional pipeline support mostly adopts a fixed structure or a simple bolt adjustment design, which has the following significant defects:

[0003] Low installation efficiency: The arc-shaped hoop of the conventional support is mostly of a split structure, and needs to be fastened through multiple bolts, which is tedious to operate. In a narrow or high-altitude working environment, it is difficult for the construction personnel to quickly align the bolt holes, resulting in time-consuming installation and safety hazards.

[0004] Limited height adjustment: The lifting mechanism of the existing support mostly relies on manual adjustment of threaded rods, which has poor adjustment accuracy and is prone to thread jamming due to oil and gas corrosion. In complex terrain (such as sloping land and soft soil foundation), it is difficult to achieve coordinated height fine adjustment of multiple supports, which is prone to stress concentration of the pipeline.

[0005] Insufficient locking reliability: Some supports use spring buckles or simple latch locks, which are prone to loosening due to long-term pipeline vibration. For example, a Chinese patent with publication number CN20XX123456A proposes a ratchet locking structure, but the ratchet cannot be reinforced again after one-way locking, and there is still a risk of slipping under extreme load.

[0006] Poor angle adaptability: When installing the turning section of the pipeline, the contact angle between the support and the pipeline needs to be adjusted to avoid local extrusion. The support base and the base of the traditional support are mostly rigidly connected, lacking rotation adjustment function, which results in poor fit between the pipeline and the support surface, accelerating the wear of the pipeline wall.

[0007] To solve the above problems, the present application proposes a petroleum pipeline support integrating hydraulic lifting, multi-directional locking and self-adaptive angle adjustment. Through the cooperative design of the hinged arc-shaped connecting piece and the ratchet-tightening composite locking mechanism, rapid opening and closing and double locking are achieved; combined with the hydraulic lifting base and the rotatable support base, the height and support angle can be accurately adjusted in complex terrain, and the risk of damage to the pipeline surface is reduced through the detachable rubber protection belt, significantly improving the construction efficiency and long-term operation stability.
