Description

Technical Field

[0001] This utility model relates to an adjustable fixing device for instrument tubes, which is mainly used in offshore oil platforms for scaling and fixing instrument tubes in structural profiles and plates. Background Technology

[0002] Offshore oil platforms are mostly steel structures. Traditionally, when installing instrument pipes, it is necessary to first measure the distance between the instrument pipes and the structural profiles and plates along the path of the instrument pipes, based on the actual site conditions. Then, based on the measured dimensions, steel supports are prefabricated on site. After prefabrication, the supports are ground, painted, and air-dried before being hoisted onto the platform and individually welded to the structure. It is also necessary to distinguish the distance between each support leg and the structure to ensure correct installation. If changes occur later, the supports need to be cut off and new supports need to be prefabricated, which is time-consuming, labor-intensive, and inefficient. Summary of the Invention

[0003] The purpose of this utility model is to provide an adjustable fixing device for instrument pipes, which can solve the problem of fixing and laying instrument pipes on offshore oil platforms. It can more conveniently change the vertical distance between the instrument pipe and the structure, saving time and effort while being firm and reliable.

[0004] To achieve the above objectives, the technical solution adopted is:

[0005] This utility model relates to an adjustable fixing device for instrument tubes, comprising a base welded to the profiles and plates of an offshore oil platform, a vertically oriented sliding rod whose bottom is fixed to the middle of the top wall of the base, the sliding rod being inserted into a sleeve rod, and having a first set of connecting holes and a second set of connecting holes with their axes perpendicular to each other on the sliding rod, the first set of connecting holes and the second set of connecting holes being spaced vertically along the axis of the sliding rod, and a third set of connecting holes being spaced vertically along the axis of the sleeve rod, the sliding rod and the sleeve rod being fixedly connected at a set position by bolts passing through the connecting holes on the sliding rod and the sleeve rod, a top plate being fixed to the top of the sleeve rod, and an instrument tube fixing clamp for fixing the instrument tube being fixed to the top plate.

[0006] The advantages of this utility model are: it can effectively solve the problem of fixing traditional instrument tubes at low cost, and save a lot of manpower during the installation process; the combination of sleeve rod and slide rod is convenient to assemble and disassemble, safe and reliable, and saves additional investment; according to the actual site conditions, the sleeve rod and slide rod can be quickly scaled up and down, saving time. Attached Figure Description

[0007] Figure 1 This is a schematic diagram of an adjustable fixing device for an instrument tube according to this utility model. Detailed Implementation

[0008] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0009] like Figure 1 An adjustable fixing device for instrument tubes is shown, comprising a base 1 welded to the profiles and plates of an offshore oil platform, a vertically oriented slide rod 3 whose bottom is fixed to the middle of the top wall of the base, the slide rod being inserted into a sleeve rod 4, the slide rod having a first set of connecting holes and a second set of connecting holes with their axes perpendicular to each other, the first and second sets of connecting holes being spaced vertically along the axis of the slide rod, and the sleeve rod having a third set of connecting holes, the third set of connecting holes being spaced vertically along the axis of the sleeve rod, the slide rod and the sleeve rod being fixedly connected at a set position by bolts passing through the connecting holes on the slide rod and the sleeve rod. A top plate is fixed to the top of the sleeve rod, and an instrument tube fixing clamp 5 for fixing the instrument tube is fixed to the top plate.

[0010] In one embodiment of this utility model, the instrument tube fixing clamp includes an upper clamp plate and a lower clamp plate that are interlocked with each other. A semi-circular groove is formed in the middle of the mating surfaces of the upper and lower clamp plates, and the two semi-circular grooves are joined together to form a clamping groove for clamping the instrument tube. The upper clamp plate, lower clamp plate, and top plate are fixedly connected by bolts 2 passing through bolt holes in the upper clamp plate, lower clamp plate, and top plate, and nuts tightened at the lower ends of the bolts.

[0011] First, weld the base to the profiles and plates of the offshore oil platform. Weld the sliding rod to the base, ensuring vertical alignment. Insert the sliding rod into the sleeve rod, connecting the sleeve rod and sliding rod with bolts through the connecting holes. Secure the instrument tubes to the sleeve rod using instrument tube clamps. The length between the sleeve rod and sliding rod can be adjusted according to actual needs. When adjustments are needed to ensure the path is perpendicular to the structural direction, loosen the bolts, select appropriate connecting holes, and re-secure the rod.
