Description

Technical Field

[0001] This utility model relates to the field of pipe coupling processing and testing technology, specifically to a pipe coupling processing and testing device for oil pipelines. Background Technology

[0002] Oil casing is a steel pipe used to support the wellbore of oil and gas wells to ensure the normal operation of the entire well after drilling and completion. Each well requires several layers of casing depending on the drilling depth and geological conditions. Oil pipeline couplings are designed for connecting oil pipelines. During the processing of oil pipeline couplings, the inspection of oil pipeline couplings plays a crucial role in determining their quality.

[0003] Chinese utility model patent, authorization announcement number CN213054476U, discloses a processing and testing device for oil pipeline couplings. The device includes a workbench with a support plate fixedly connected to its top. A support rod is fixedly connected to the left side of the support plate. By rotating a handle, the device causes a threaded rod to rotate, which in turn moves a fixed rod within a movable groove on the surface of the threaded rod. When the fixed rod reaches a suitable position, a second fixing ring is rotated to fix the position of the fixed rod. This allows the device to clamp small and medium-sized oil pipeline couplings of different sizes, making it easier for workers to inspect the internal threads of these couplings.

[0004] The above-mentioned solution still has certain defects in practical applications. For example, the device uses two arc-shaped clamping plates to clamp and fix the pipe couplings. Since the diameter of the clamped pipe couplings is fixed, the existing technology is not convenient for clamping and fixing pipe couplings of different sizes and lengths, resulting in poor practicality. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-3 As shown, this utility model provides a technical solution: a processing and testing device for oil pipeline couplings, including a workbench 1, with two support plates 2 inside the workbench 1, and clamping components 4 on the sides of the support plates 2, which clamp circular pipe couplings of different diameters.

[0025] like Figure 1 and Figure 3 As shown, the clamping assembly 4 includes a movable plate 401 that is movably inserted into the support plate 2. Side plates 402 are integrally formed on both sides of the bottom of the movable plate 401. A pressing round head 403 is fixed at the end of the side plate 402. S-shaped push plates are movably connected to both sides of the top of the support plate 2 through pins 408. The push plate includes a top plate 404 and a bottom plate 405. A slope is formed on the side of the bottom plate 405 facing the pressing round head 403. The bottom plate 405 is in contact with the pressing round head 403.

[0026] To clamp circular pipe couplings of different diameters, a support base 409 is fixed at the bottom of the support plate 2, and an electric telescopic rod 410 is fixed at the top of the support base 409. The telescopic end of the electric telescopic rod 410 is fixed to the movable plate 401. When the electric telescopic rod 410 extends or retracts, the movable plate 401 moves upward, and the top plates 404 on both sides move relative to the movable plate 401, thereby clamping the circular pipe coupling.

[0027] After clamping the circular pipe coupling, in order to rotate the circular pipe coupling and facilitate the inspection of the outer surface and internal threads of the circular pipe coupling, a bottom circular block 406 is movably connected to the top of the movable plate 401, and a top circular block 407 is movably connected to the top of each of the two top plates 404. In order to increase the friction between the top circular block 407 and the bottom circular block 406 on the circular pipe coupling, in this solution, the top circular block 407 and the bottom circular block 406 are both made of rubber material.

[0028] The bottom of the two support plates 2 is equipped with a driving component, which drives the two support plates 2 to move in opposite directions and in reverse, thereby clamping circular pipe couplings of different lengths.

[0029] Among them, such as Figure 2 As shown, the driving component includes a bidirectional lead screw 301 and a guide rod 302. The two sides of the bidirectional lead screw 301 are respectively movably screwed to two support plates 2, and the guide rod 302 is movably inserted into the two support plates 2. A knob 303 is fixed at the end of the bidirectional lead screw 301 that extends out of the worktable 1. Rotating the knob 303 rotates the bidirectional lead screw 301. Since the thread directions on both sides of the bidirectional lead screw 301 are opposite, the two support plates 2 can move towards each other or away from each other, thereby enabling the clamping of circular pipe couplings of different lengths.

[0030] Working principle:

[0031] When using this oil pipeline coupling processing and testing device, depending on the length of the coupling, the double-ended lead screw 301 can be rotated by turning the knob 303. Since the threads on both sides of the double-ended lead screw 301 are in opposite directions, it drives the two support plates 2 to move towards or away from each other along the guide rod 302, thereby adjusting the distance between the two support plates 2 and realizing the length adjustment of couplings of different lengths. When it is necessary to clamp the coupling, the electric telescopic rod 410 is activated. The electric telescopic rod 410 extends and pushes the movable plate 401 upward. During the upward movement of the movable plate 401, the pressing round head 403 at the end of the side plate 402 will slide upward along the slope of the bottom plate 405. Because the push plate is connected to the pin 408... The support plate 2 is movably connected, so under the upward sliding action of the pressing round head 403, the top plates 404 on both sides will move relative to the movable plate 401, using the top round block 407 and the bottom round block 406 to clamp the pipe coupling. After the pipe coupling is firmly clamped, the outer surface and internal threads of the pipe coupling can be inspected. If it is necessary to rotate the pipe coupling for all-round inspection, since there is a certain friction between the top round block 407 and the bottom round block 406 and the pipe coupling, when a certain torque is applied by the external inspection equipment, the pipe coupling can be rotated under the action of the top round block 407 and the bottom round block 406, which facilitates the staff to conduct comprehensive and detailed inspection of all parts of the pipe coupling.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
