[0025] In order to enable those skilled in the art to better understand the technical solutions in the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the 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 of 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.

[0026] Refer to Figure 1, in an embodiment of the present utility model, the oil and gas recovery anti-oblique pull test equipment includes a fixture assembly 1, an adjustment assembly 2 cooperatively installed with the fixture assembly 1, and a connection block 3.

[0027] Referring to Figure 1 , the fixture assembly 1 is used to hold the test joint ( Figure 1 shown as marked a in

[0028] Referring to Figure 1 and Figure 2 , the fixture assembly 1 includes a first chuck 11 and a second chuck 12 that hold the test joint in a preset position. The first chuck 11 and / or the second chuck 12 are provided with a flow channel 13 that is in liquid communication with the test joint, so as to apply a preset hydraulic pressure to the test joint through the flow channel 13. The first chuck 11 and / or the second chuck 12 are provided with mounting holes that are threadedly connected to the test joint. In this embodiment, the first chuck 11 is provided with a mounting hole, and the second chuck 12 is provided with a flow channel 13. In other embodiments, the flow channel 13 or the mounting hole may also be provided in different chucks.

[0029] Among them, when testing the anti-oblique pull performance of the test joint, on the one hand, a tensile force is applied to the test joint through the fixture assembly 1; on the other hand, a preset hydraulic pressure is applied to the test joint through the flow channel 13. Therefore, the use environment of the test joint actually applied to the oil and gas pipeline can be effectively simulated, so as to further ensure the test result of the anti-oblique pull performance of the test joint.

[0030] Referring to Figure 1 , the adjustment assembly 2 includes a rotating member 21 and a translating member 22. The rotating member 21 is used to provide the fixture assembly 1 with a rotational degree of freedom about its axis, and the translating member 22 is used to provide the fixture assembly 1 with a translational degree of freedom along a preset direction, where the preset direction is perpendicular to the direction of the tensile force that can be applied to the fixture assembly 1.

[0031] Referring to Figure 1 , the connection block 3 is cooperatively installed with the translating member 22, and the connection block 3 is arranged to be translatable along the preset direction. One end of the rotating member 21 is fixedly connected to the fixture assembly 1, and the other end is rotatably installed in the connection block 3, so that the fixture assembly 1 rotates about its axis.

[0032] Referring to Figure 2 and Figure 3, the rotating member 21 includes a connecting seat 211 fixedly connected to the fixture assembly 1 and a clamping block 212 fixed to the side of the connecting seat 211 away from the fixture assembly 1. The connecting block 3 is provided with a clamping groove 31, and the clamping block 212 is axially limited in the clamping groove 31 within the fixture assembly 1, and the clamping groove 31 is provided with a space for the clamping block 212 to rotate around the axis of the fixture assembly 1. In combination with Figure 1 , a fixing hole for the fixture assembly 1 to pass through is provided on the side of the connecting seat 211 close to the fixture assembly 1, and the fixture assembly 1 is limited within the connecting seat 211 by a pin. In this embodiment, the second chuck 12 is provided with a limiting head passing through the fixing hole, and the second chuck 12 and the connecting block 3 can be effectively fixed by the pin.

[0033] Referring to Figure 1 , the surface of the connecting block 3 away from the translation member 22 is set as an inclined surface, and the inclined surface is used to keep the test joint in a preset position. In this embodiment, the clamping groove 31 is provided at the inclined surface, and the axis of the fixture assembly 1 is perpendicular to the inclined surface. Therefore, by setting the inclined surface, an included angle can be formed between the axis of the test joint and the direction of the pulling force that can be applied to the fixture.

[0034] It can be understood that if it is necessary to make the test joint at different inclined angles, the connecting block 3 with inclined surfaces of different inclined angles can also be installed on the translation member 22.

[0035] Referring to Figure 1 , the translation member 22 includes a sliding block 221 and a sliding rail 222 that are slidably connected. The connecting block 3 is fixedly connected to the side of the sliding block 221 away from the sliding rail 222, and the sliding rail 222 extends along a preset direction. In this embodiment, the translation member 22 further includes a limiting rod 223, and the limiting rod 223 is installed at both ends of the sliding rail 222 for abutting against and restricting the sliding block 221 from sliding off the sliding rail 222.

[0036] Referring to Figure 1 , the oil and gas recovery anti-oblique pull test equipment of this embodiment further includes a first connector 4 and a second connector 5. The first connector 4 is movably connected to the fixture assembly 1, and the second connector 5 is fixedly connected to the surface of the sliding rail 222 away from the sliding block 221. Tensile forces are applied to both ends of the fixture assembly 1 through the first connector 4 and the second connector 5. In this embodiment, the first connector 4 is hinged to the first chuck 11, and the second connector 5 is fixedly connected to the sliding rail 222 by screws.

[0037] When the oil and gas recovery anti-oblique pull test equipment of the present utility model is in operation, the second connector 5 remains stationary, and a tensile force along its axial direction is applied to the fixture assembly 1 through the first connector 4, so as to apply a tensile force at an angle to the axial direction of the test connector itself. During the application of the tensile force, the rotating member 21 enables the fixture assembly 1 to rotate adaptively around its axial direction, and the translating member 22 enables the fixture assembly 1 to translate adaptively along a preset direction. Under the action of the tensile force, finally, the relative positions of all structures remain stationary, so that the data of the anti-oblique pull test performance of the test connector can be detected and obtained.

[0038] Among them, in this embodiment, on the one hand, the setting of the slide rail 222 can provide the translational freedom for the fixture assembly 1 to move along the preset direction, so that it can be adjusted adaptively. On the other hand, since the slide rail 222 has a certain length, the oil and gas recovery anti-oblique pull test equipment of the present utility model can also adapt to test connectors of different lengths, effectively improving the applicable range of the oil and gas recovery anti-oblique pull test equipment of the present utility model.
