Description

Technical Field

[0001] This invention relates to the field of manifolds, specifically to a quick fixing device for throttling and killing manifolds. Background Technology

[0002] A manifold is a combination of multiple pipes that come together. It includes gate valves, pipelines, pipe fittings, pressure gauges, and accessories such as electronic sensors and hydraulic control systems. There are many types of manifolds, each with different uses due to its different construction. Common types of manifolds include throttling manifolds, pressure testing manifolds, ring manifolds, and well kill manifolds.

[0003] In existing technologies, choke and kill manifolds are typically assembled using positioning devices to secure the manifold. These devices involve placing one flange end of the component to be installed on an arc-shaped plate, with the other flange end positioned on the upper surfaces of a first and second connecting plate. The distance between the arc-shaped plate and the first connecting plate can be adjusted by sliding a horizontal plate on a slide rod to accommodate different component lengths. Rotating the first handwheel drives the lead screw to rotate, causing the first slider to slide within the second groove, moving the entire positioning assembly and achieving horizontal movement of the component to be installed. Pushing the push handle then aligns this component with the flange end of another already installed component, enabling rapid installation.

[0004] However, when the flange end to be installed is placed on the arc plate, the horizontal plate moves with the arc plate when the horizontal plate is moved. This cannot guarantee that the flange end on the arc plate will not be displaced, and if the flange end moves, it will affect the installation of the manifold. Summary of the Invention

[0005] The purpose of this invention is to provide a quick fixing device for choke and kill manifolds to solve the problems mentioned in the background art.

The guide groove is opened on the surface of the movable plate and has a cross-shaped groove structure. The limiting baffle has an arc-shaped plate structure and passes through the limiting slot. The limiting slot is opened on the surface of the arc-shaped plate. The surface of the limiting baffle has a guide arc surface and the limiting baffle is in contact with the surface of the manifold flange end.

[0011] Preferably, the control component includes a rotating cylinder, a handle, a baffle, a limit rod, and a traction rope.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The quick fixing device for throttling and killing manifolds proposed in this invention allows for the following steps: After the manifold flange is positioned, pull the limiting rod to detach one end from the surface of the baffle. Then, rotate the handle to rotate the rotating cylinder. During the rotation of the rotating cylinder, the traction rope wraps around the rotating cylinder. The traction rope pulls the connecting plate along the positioning rod towards the center of the positioning rod. The movement of the connecting plate moves the limiting baffle until it passes through the limiting slot. The limiting slot then limits the manifold flange end. Even if the movable plate moves along the surface of the sliding rod, it can prevent displacement of the manifold flange end, allowing for better assembly of the manifold flange end.

During the rotation of the rotating cylinder 12, the traction rope 19 is wound around the rotating cylinder 12. The traction rope 19 pulls the connecting plate 20 to move along the positioning rod 11 towards the center of the positioning rod 11. The movement of the connecting plate 20 can drive the limiting baffle 24 to move until the limiting baffle 24 passes through the limiting slot 8. The limiting slot 8 can limit the manifold flange end 9. Even if the movable plate 5 moves along the surface of the sliding rod 2, it can prevent the manifold flange end 9 from being displaced, so that the manifold flange end 9 can be better assembled.

[0026] Example 2

[0027] Based on Embodiment 1, to prevent displacement of the manifold flange end 9 and to facilitate better assembly, the positioning plate 1 is a square plate structure, and the sliding rod 2 is a cylindrical structure. Two sets of sliding rods 2 are symmetrically distributed about the center of the positioning plate 1. Push plates 3 and overlapping plates 4 are respectively provided at both ends of the two sets of sliding rods 2. The overlapping assembly includes a movable plate 5 and an arc-shaped plate 7. The movable plate 5 is a square plate structure with through holes 6 on its surface, through which the sliding rod 2 passes. The arc-shaped plate 7 is an L-shaped arc plate structure fixed to the surface of the movable plate 5. A mounting plate 10 is provided on the surface of the movable plate 5, and the positioning rod 11 is fixed to the surface of the mounting plate 10. Positioning rod 11 has an "I"-shaped column structure. The limiting assembly includes a connecting plate 20, a guide slide plate 22, and a limiting baffle 24. The connecting plate 20 has an "L"-shaped plate structure, and a movable opening 21 is provided on the surface of the connecting plate 20. The positioning rod 11 passes through the movable opening 21. There are two sets of connecting plates 20, which are symmetrically distributed about the center of the movable plate 5. The surface of the connecting plate 20 is provided with a guide slide plate 22, which has a "+"-shaped plate structure and is slidably connected to the surface of the guide groove 23. The guide groove 23 is opened on the surface of the movable plate 5 and has a "+"-shaped groove structure. The limiting baffle 24 has an arc-shaped plate structure and passes through the limiting slot 8. The limiting slot 8 is opened on the arc-shaped plate 7. The surface of the limiting baffle 24 is provided with a guide arc surface 25, and the limiting baffle 24 is in contact with the surface of the manifold flange end 9. The control assembly includes a rotating cylinder 12, a handle 13, a baffle 14, a limiting rod 16, and a traction rope 19. The rotating cylinder 12 is rotatably connected to the surface of the positioning rod 11. The rotating cylinder 12 has a cylindrical structure. The surface of the rotating cylinder 12 is provided with a handle 13, which has a square plate structure. There are two sets of handles 13, which are symmetrically distributed about the center of the rotating cylinder 12. The surface of the rotating cylinder 12 is provided with a baffle 14, which has a circular plate structure and is in contact with the surface of the movable plate 5. The limiting rod 16 is movably inserted into the surface of the handle 13. The surface of the handle 13 is provided with an insertion hole 15. The structure is T-shaped. The limiting rod 16 passes through the insertion hole 15, which penetrates the surface of the baffle 14. The traction rope 19 is fixed to the surface of the rotating cylinder 12, with one end of the traction rope 19 fixed to the surface of the connecting plate 20. A guide plate 17 is provided on the surface of the limiting rod 16. The guide plate 17 has a circular plate structure and two sets of insertion holes 15, which are symmetrically distributed about the center of the handle 13. A support spring 18 is provided between the surfaces of the mounting plate 10 and the connecting plate 20. The support spring 18 is sleeved on the outside of the positioning rod 11. When the manifold flange end 9 is placed between the surfaces of the arc-shaped plate 7, the connecting plate 20 is pushed by the support spring 18 and moves away from the center of the positioning rod 11. At this time, the limiting baffle 24 does not pass through the limiting slot 8.After placing the manifold flange end 9, pull the limiting rod 16 so that one end detaches from the surface of the baffle 14. Then, turn the handle 13 to drive the rotating cylinder 12 to rotate. During the rotation of the rotating cylinder 12, the traction rope 19 is wound around the rotating cylinder 12. During the winding process, the traction rope 19 pulls the connecting plate 20 to move along the positioning rod 11 towards the center of the positioning rod 11. The movement of the connecting plate 20 will drive the limiting baffle 24 to move until the limiting baffle 24 passes through the limiting slot 8. The limiting slot 8 can then limit the manifold flange end 9, allowing the movable plate 5 to move along the surface of the sliding rod 2.

[0028] In actual use, the manifold flange end 9 is placed between the surfaces of the arc plate 7. The connecting plate 20 is supported by the spring 18 and moves away from the center of the positioning rod 11. At this time, the limiting baffle 24 does not pass through the limiting slot 8. After the manifold flange end 9 is placed, the limiting rod 16 is pulled so that one end of it is detached from the surface of the baffle 14. Then, the handle 13 is turned to drive the rotating cylinder 12 to rotate. During the rotation of the rotating cylinder 12, the traction rope 19 is wound around the rotating cylinder 12. During the winding process, the traction rope 19 pulls the connecting plate 20 along the positioning rod 11 towards the center of the positioning rod 11. The movement of the connecting plate 20 can drive the limiting baffle 24 to move until the limiting baffle 24 passes through the limiting slot 8. The limiting slot 8 can limit the manifold flange end 9. Even if the movable plate 5 is moved along the surface of the sliding rod 2, it can prevent the manifold flange end 9 from being displaced, so that the manifold flange end 9 can be better assembled.
