Description

Technical Field

[0001] This utility model relates to the field of outdoor construction wellhead protection, and in particular to a novel reusable wellhead safety protection tool. Background Technology

[0002] For example, Chinese utility model patent publication number CN 217379834 U discloses an insertable wellhead protection device, including a hoop ring and an insert ring. The hoop ring is positioned above the wellhead, and the insert ring is positioned inside the wellhead. The insert ring is a telescopic ring, and the hoop ring and the insert ring are connected by a connecting rod. However, this device is not convenient to protrude from the wellhead surface, makes it inconvenient to install fall protection signs, and provides insufficiently clear warnings. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a new type of reusable wellhead safety protection tool, which can protrude above the wellhead for easy installation of anti-fall signage and can also adapt to different specifications of locking ring beams.

[0004] To address the aforementioned issues, a new type of reusable wellhead safety protection tool has been developed, comprising:

[0005] Upper hoop;

[0006] Diagonal brace, with a circular hoop hinged to its upper end, and arranged at intervals;

[0007] The hinge joint is of the cross type, including a first bushing and a second bushing that is cross-hinged with the first bushing, wherein the first bushing is slidably sleeved on the diagonal bar;

[0008] The lower circular hoop is slidably fitted into the second bushing;

[0009] The threaded strips are spaced apart at the end of the first bushing and wrap around it, with the threaded strips extending outward in an arc shape.

[0010] A rubber pad is laid on the inner side of the threaded strip;

[0011] A nut, which is connected to a threaded strip around the thread and is located at the root of the threaded strip.

[0012] As a further improvement of this utility model, the space between the inclined rod and the lower circular hoop is a locking ring beam at the wellhead; the hinge joint allows the lower circular hoop to move up and down along the inclined rod to adapt to locking ring beams of different widths; after the nut is tightened, the threaded strip retracts, and the rubber pad is pressed against the inclined rod to achieve locking.

[0013] As a further improvement of this utility model, the inclined rod is formed by multiple threaded rods connected by threads. One end of the threaded rod is a threaded sleeve, and the other end is a stepped threaded end, which is adapted to the threaded sleeve.

[0014] With this structure, in actual use, if the diagonal bar is too long, a section of the threaded bar can be removed.

[0015] As a further improvement of this utility model, a ring of anti-fall signs is provided on the lower circular hoop.

[0016] With this structure, the fall protection signs are installed inside, making them less susceptible to damage.

[0017] As a further improvement of this utility model, a ring of studs is arranged at intervals on the lower side of the lower circular hoop, and the studs are adapted to the threaded sleeve.

[0018] With this structure, the stud can be extended after being connected to the removed threaded rod to accommodate lock ring beams of different heights.

[0019] As a further improvement of this utility model, an L-shaped limiting tube is installed at the lower end of the stud, and the upper end of the L-shaped limiting tube is threadedly adapted to the stud and the threaded end.

[0020] With this structure, the L-shaped limiting tube can be easily clamped onto the lower side of the lock ring beam at the variable cross-section.

[0021] As a further improvement of this utility model, the lower end of the L-shaped limiting tube is threadedly connected to a sleeve.

[0022] With this structure, the casing can be tightened to abut against the inner wall of the well, thus achieving a limiting position.

[0023] This utility model protrudes above the wellhead, making it easy to install fall protection signs. It can also adapt to different specifications of lock ring beams, making it easy to reuse. The fall protection signs can be fitted with or affixed with reflective warning signs, which are especially effective during nighttime construction. Attached Figure Description
