[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment 1

[0023] As Figure 1 shown:

[0024] The workover quick make-up and break-out blowout preventer nipple includes a bracket 1.

[0025] In this implementation: The existing publication number: CN218542198U discloses a workover quick make-up and break-out blowout preventer nipple; to solve the technical problems existing in this prior art, as disclosed in the above background art, "This device can only clamp materials of a single diameter. Then, in subsequent work, materials of different diameters may be used. At this time, the applicable range of this device is limited, which is not conducive to a stable work process." In combination, this problem is obviously a real and relatively difficult problem to solve. In view of this, to solve the above problem, a clamping block 2 and a fixed plate 3 are added on this basis.

[0026] Furthermore:

[0027] As Figure 1 - Figure 4 shown:

[0028] Combined with the above: It also includes a clamping block 2, a fixed plate 3, a sliding groove 4, a stabilizing rod 5, a moving plate 6, a stabilizing groove 7 and a hydraulic rod 8 provided on one side of the bracket 1. One side of the bracket 1 is slidably connected to the surface of the clamping block 2, and the clamping block 2 penetrates through the bracket 1 and is slidably connected to the fixed plate 3. Meanwhile, a sliding groove 4 slidably connected to the bracket 1 is also formed on the surface of the fixed plate 3. One side of the sliding groove 4 is fixedly connected to one end of the stabilizing rod 5, and the other end of the stabilizing rod 5 is slidably connected to the stabilizing groove 7 formed on the inner surface of the moving plate 6. One side of the moving plate 6 is in close contact with the surface of the hydraulic rod 8, and the hydraulic rod 8 is fixedly installed on the surface of the bracket 1.

[0029] In this embodiment: When performing the make-and-break operation, the positions of the fixed plate 3 and the moving plate 6 can be adjusted according to the different diameters of the materials. First, the clamping block 2 can be separated from between the bracket 1 and the clamping block 2. At this time, the fixed plate 3 can slide relative to the bracket 1 through the sliding groove 4. Subsequently, the groove formed on the surface of the fixed plate 3 can be moved to the corresponding position according to the diameter of the material, and then the clamping block 2 can be connected to between the bracket 1 and the fixed plate 3 again. Then, the hydraulic rod 8 can be controlled to exert a thrust on the moving plate 6, and the moving plate 6 will slide relative to the stabilizing rod 5 through the stabilizing groove 7 formed on its inner surface until the fixed plate 3 and the moving plate 6 complete the extrusion work on the material. When performing the make-and-break operation on materials with other diameters, the positions of the fixed plate 3 and the moving plate 6 can be adjusted again.

[0030] Furthermore:

[0031] In an alternative embodiment, a rectangular through-hole matching the clamping block 2 is formed on the surface of the bracket 1.

[0032] In this embodiment: The through-hole formed on the surface of the bracket 1 enables the clamping block 2 to pass over the bracket 1 and fix the fixed plate 3, which can prevent the fixed plate 3 from loosening during the extrusion process.

[0033] Furthermore:

[0034] In an alternative embodiment, semi-circular grooves with different diameters are equidistantly formed on the surfaces of the fixed plate 3 and the moving plate 6.

[0035] In this embodiment: The equidistantly formed grooves can perform extrusion according to the diameters of different materials, and thus the device can extrude materials with different diameters, making it highly flexible.

[0036] Furthermore:

[0037] In an alternative embodiment, the sliding groove 4 is rectangular in shape and matches the shape of the bracket 1.

[0038] In this embodiment: The connection between the sliding groove 4 and the bracket 1 enables the position adjustment of the fixed plate 3 and the moving plate 6 to be realized stably, and thus the extrusion work on materials with different diameters can be carried out.

[0039] Furthermore:

[0040] In an alternative embodiment, the stabilizing rods 5 are symmetrically arranged on both sides of the surface of the fixed plate 3, and the shape of the stabilizing groove 7 matches that of the stabilizing rods 5.

[0041] In this embodiment: The symmetrically arranged stabilizing rods 5 on the surface of the fixed plate 3 can ensure the docking work between the fixed plate 3 and the moving plate 6 is more stable when relative displacement occurs between them.

[0042] Furthermore:

[0043] In an alternative embodiment, the hydraulic rod 8 is located at the midpoint of the bracket 1.

[0044] In this embodiment: The hydraulic rod 8 located at the midpoint of the bracket 1 can, when generating a thrust on the moving plate 6, enable the moving plate 6 and the fixed plate 3 to generate a stable extrusion force on the blowout preventer nipple, and thus the installation work can be completed just right.

[0045] The working principle and usage process of the present utility model: When carrying out the make-up and break-out work, the positions of the fixed plate 3 and the moving plate 6 can be adjusted according to the different diameters of the materials. First, the clamping blocks 2 can be separated from between the bracket 1 and the clamping blocks 2. At this time, the fixed plate 3 can slide between the sliding groove 4 and the bracket 1. Subsequently, the groove opened on the surface of the fixed plate 3 can be moved to the corresponding position according to the diameter of the material, and then the clamping blocks 2 are connected between the bracket 1 and the fixed plate 3 again. Subsequently, the hydraulic rod 8 can be controlled to generate a thrust on the moving plate 6, and the moving plate 6 will slide between the stabilizing groove 7 opened on its inner surface and the stabilizing rods 5 until the fixed plate 3 and the moving plate 6 complete the extrusion work on the material. When carrying out the make-up and break-out work on materials with other diameters, the positions of the fixed plate 3 and the moving plate 6 can be adjusted again.

[0046] Finally, it should be noted that: The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
