Description

Technical Field

[0001] The utility model relates to the technical field of pipeline emergency rescue, in particular to a three-petal pipe clamp for emergency stabilization of long-distance oil and gas pipelines. Background Art

[0002] Long-distance oil and gas pipelines are the core pipelines for cross-regional transmission and distribution of natural gas, and play a key role in the transmission and distribution of natural gas to urban gas distribution centers and industrial enterprises.

[0003] Long-distance oil and gas pipelines are often left suspended due to factors like water erosion, which can lead to soil loss around the pipeline and loss of support at the bottom, potentially endangering production safety. The main causes of suspended pipelines include: severe weather conditions that hollow out the soil around the pipeline, illegal sand and stone mining by third-party operators in rivers, which gradually thins the soil covering the pipeline's crossing section. Suspended pipelines can also cause severe deformation and distortion, and in severe cases, can even rupture, leading to massive natural gas leaks and serious safety incidents.

[0004] During the operation of long-distance oil and gas pipelines, due to factors such as changing geological conditions, natural disasters, or human factors, the pipelines may be subjected to external forces or displacement, resulting in decreased pipeline stability and even safety accidents such as leaks. Traditional pipeline reinforcement methods often use bolting or welding. These methods are not only complex and time-consuming in emergency situations, but also difficult to quickly adapt to pipelines of different diameters and shapes. Utility Model Content

[0005] The purpose of the utility model is to provide a three-petal pipe clamp for emergency stabilization of long-distance oil and gas pipelines. The pipe clamp has the characteristics of simple structure, convenient installation, strong adaptability and good fixing effect, and can quickly stabilize and reinforce long-distance oil and gas pipelines in emergency situations.

[0006] The technical solutions adopted to achieve the above objectives are as follows:

[0007] A three-petal pipe clamp for emergency stabilization of long-distance oil and gas pipelines comprises a left arc-shaped clamp, a right arc-shaped clamp and a lower arc-shaped clamp, wherein the connecting ends of the left arc-shaped clamp, the right arc-shaped clamp and the lower arc-shaped clamp are connected by a connecting mechanism, and the connecting ends of the right arc-shaped clamp and the lower arc-shaped clamp are connected by a locking mechanism, the inner arc surface surrounded by each arc-shaped clamp is provided with a rubber pad layer, a base assembly is provided under the lower arc-shaped clamp, and two lifting ears are welded on the connecting mechanism connecting the left arc-shaped clamp and the right arc-shaped clamp.

[0008] Furthermore, the connection mechanism includes a male hinge assembly and a female hinge assembly, which are connected by a pin assembly in the middle;

[0009] A left lifting lug and a right lifting lug are symmetrically welded on the convex hinge assembly and the concave hinge assembly of the connection mechanism connecting the left arc-shaped splint and the right arc-shaped splint.

[0010] Furthermore, the locking mechanism includes a movable pull rod, a locking nut, a locking seat, a pin shaft and a single-sided hinge, wherein the movable pull rod is fixed to the right end of the lower arc-shaped splint through a rotating hinge formed by the pin shaft and the single-sided hinge, the locking seat is fixed to the lower end of the right arc-shaped splint, and the locking nut is used to cooperate with the thread on the upper part of the movable pull rod.

[0011] Furthermore, the base assembly includes a notch guard plate, a left support plate, a middle support plate, a middle support plate auxiliary neck, a lower base plate and a right support plate. The various parts are connected by welding to form a base assembly. Four bolts are provided on the bottom surface of the lower arc-shaped splint corresponding to the notch position of the notch guard plate, which are used to fix the notch on the notch guard plate by cooperating with the notch on the notch guard plate through tightening nuts.

[0012] The beneficial effects of the utility model are as follows:

[0013] 1. Good fixing effect: The pipe clamp connection mechanism 1 connects the concave and convex loose-leaf components through a pin with a hole, and is locked by the locking mechanism 2, thereby realizing multi-point fixation of the long-distance oil and gas pipeline and improving the stability of the pipeline.

[0016] 4. The utility model ensures the safe operation of the pipeline and reduces the potential risks caused by the pipeline hanging in the air, provides convenience for gas pipeline maintenance, and also reduces the risk of gas transmission outage. BRIEF DESCRIPTION OF THE DRAWINGS

A rubber pad 4 is adhered to the inner arc surface formed by the pipe clamp connecting mechanism 1, the locking mechanism 2 and the arc-shaped splint 3 to ensure that the rubber pad 4 fits tightly with the outer wall of the pipe, which can increase the friction between the pipe clamp and the pipe during emergency pipe stabilization and prevent the anti-corrosion layer of the pipe from being damaged when the pipe clamp is used. This structure can achieve low-stress effective clamping of suspended pipes, and after the base assembly 5 is fixed to other stable foundations by bolts, it can achieve stable clamping of suspended pipes.

The convex hinge assembly 12 and the concave hinge assembly 14 are connected by the pin assembly 13 to form a movable joint, which is convenient for flipping the pipe clamp when in use. In addition, in order to facilitate the lifting operation during pulling operations, a left lifting ear 11 and a right lifting ear 15 are symmetrically welded on the convex hinge assembly 12 and the concave hinge assembly 14 to achieve symmetrical bilateral lifting, thereby enhancing the safety and stability of the lifting.

[0026] The locking mechanism 2 of the present invention is as follows Figure 3 As shown, it comprises five parts: a movable rod 21, a locking nut 22, a locking seat 23, a pin assembly 24 and a concave hinge assembly 25, wherein the movable rod 21 forms a rotary hinge with the concave hinge assembly 25 through the pin assembly 24; the locking nut 22 cooperates with the thread on the upper part of the movable rod 21; the locking seat 23 cooperates with the thread on the upper part of the movable rod 21; Figure 5 The arc-shaped splint 3 is welded to the upper right arc-shaped splint 32; the concave hinge assembly 25 is fixed by welding as shown Figure 5 When in use, the two locking nuts 22 are rotated on the threaded end of the movable pull rod 21 to achieve rotational compression; when removing the pipe clamp, the clamp is opened by loosening the compression nut 22 and flipping it open from the notch of the locking seat 23;

Together with the lower arc-shaped clamp 33 located at the pipe clamp, they are welded with the connecting mechanism 1 and the locking mechanism 2 to form a circular pipe covering surface. The inner side is connected to the pipe clamp. Figure 1 The rubber pad 4 shown is bonded to the rubber surface to prevent the anti-corrosion layer on the pipe surface from being pinched when clamping; the lower arc-shaped clamping plate 33 located at the pipe clamp is as shown in FIG. Figure 4 As shown in (b), four identical bolts 331 and compression nuts 332 are provided on it.
