[0029] The deflection adjustment mechanism 6 includes a fixed platform 61, an adjustment platform 1 62 and an adjustment platform 2 63, wherein the fixed platform 61 is fixedly arranged on the support platform 5, a spherical groove 1 is opened on the fixed platform 61, the adjustment platform 1 62 has a hemispherical bottom and is rotatably arranged in the spherical groove 1, the adjustment platform 1 62 has a spherical groove 2, and the adjustment platform 2 63 has a hemispherical bottom and is rotatably arranged in the spherical groove 2;

[0030] The spherical groove 1 is provided with an arc groove 611, and the fixed platform 61 is provided with an arc hydraulic cavity 612, and the arc hydraulic cavity 612 is connected to an external hydraulic driving mechanism 1 through a hydraulic pipe;

[0031] An arc-shaped clamping block 621 is fixedly provided on the adjusting platform 62, and an arc-shaped hydraulic rod 622 is fixedly provided on the arc-shaped clamping block 621;

[0032] The arc-shaped clamping block 621 is inserted into the arc-shaped groove 611 and slides along the arc-shaped groove 611, and the arc-shaped hydraulic rod 622 slides sealingly along the arc-shaped hydraulic chamber 612;

[0033] The second spherical groove is provided with a second arc groove 623, and the first adjustment platform 62 is provided with a second arc hydraulic cavity 624, and the second arc hydraulic cavity 624 is connected to the second external hydraulic driving mechanism through a hydraulic pipe;

[0034] The second adjusting platform 63 is fixedly provided with a second arc-shaped clamping block 631, and the second arc-shaped hydraulic rod 632 is fixedly provided on the second arc-shaped clamping block 631;

[0035] The second arc-shaped clamping block 631 is inserted into the second arc-shaped groove 623 and slides along the second arc-shaped groove 623 , and the second arc-shaped hydraulic rod 632 slides sealingly along the second arc-shaped hydraulic chamber 624 .

[0036] During implementation, the vehicle body 1 is moved to the oil well to be detected, and then the vehicle body 1 is propped up by the fixed support mechanism 4, and the support heights of the fixed support mechanisms 4 are adjusted according to the inclination of the vehicle body 1, so that the vehicle body 1 is kept in a horizontal position, and then the hoisting mechanism 2 is extended so that the hoisting hoist 24 and the pulley 25 on the hoisting mechanism 2 are aligned with the wellhead. In this process, the hoisting mechanism 2 is adjusted to deflect by the deflection adjustment mechanism 6, that is, the hoisting seat 21 is adjusted to the wellhead by the rotation of the adjustment platform 1 62 along the fixed platform 61 and the rotation of the adjustment platform 2 63 along the adjustment platform 1 62. It is capable of performing multi-angle and all-round deflection around the fixed platform 61, and thus can adjust the orientation of the lifting hoist 24 and the pulley 25 so that the rolling direction of the pulley 25 is the same as the direction of the oil well, thereby ensuring that no deviation occurs when lowering cables and wires and effectively reducing the vibration generated by the wires and cables, thereby ensuring the stability of the detection instrument during the detection process and improving the accuracy of the detection results. In the process of the vehicle driving after the detection is completed, the sliding and deviation of the support platform 5 on the vehicle body 1 can effectively reduce the impact on the lifting mechanism 2, the winch 3 and the detection instrument, thereby ensuring the stability of the detection instrument during transportation.

[0037] In this embodiment, Figure 1 The lifting mechanism 2 includes a lifting seat 21, a telescopic arm 22, a hydraulic telescopic rod 23, a lifting hoist 24 and a pulley 25, wherein the lifting seat 21 is fixedly set on the adjusting platform 2 63, and the telescopic arm 22 is rotatably set on the lifting seat 21. A hydraulic telescopic rod 23 is hinged between the telescopic arm 22 and the lifting seat 21, and the lifting hoist 24 and the pulley 25 are set at the output end of the telescopic arm 22.

[0038] In this embodiment, Figure 3The fixed support mechanism 4 includes a support seat 41, a telescopic support arm 42, a hydraulic telescopic rod 43 and a support foot 44, wherein the support seat 41 is rotatably set on the vehicle body 1, the telescopic support arm 42 is rotatably set on the support seat 41, a hydraulic telescopic rod 43 is hinged between the telescopic support arm 42 and the support seat 41, and a support foot 44 is rotatably set at the output end of the telescopic support arm 42, and a throwing and grabbing spike is set on the surface of the support foot 44.

[0039] The fixed support mechanism 4 is provided in plurality, and the telescopic support arm 42 can be deflected along the support seat 41, so that the plurality of fixed support mechanisms 4 can lift the vehicle body 1 to different heights, so that the vehicle body 1 can remain horizontal under complex terrain, effectively reducing the deviation of the lifting mechanism 2 and the winch 3, and detecting stability.

[0040] In this embodiment, Figure 4 and Figure 5 The vehicle body 1 is provided with an arc-shaped slide groove 11, and an arc-shaped offset groove 12 is provided at the bottom of the arc-shaped slide groove 11. A card plate 13 is slidably arranged in the arc-shaped offset groove 12. Both sides of the card plate 13 are connected to the vehicle body 1 through a plurality of springs, and a limiting groove is arranged on the card plate 13;

[0041] An arc-shaped guide block 51 is disposed at the bottom of the support platform 5 , and the arc-shaped guide block 51 slides and rotates along the arc-shaped slide groove 11 . A limit plate 52 is fixedly disposed on the arc-shaped guide block 51 , and the limit plate 52 is inserted into the limit groove and slides along the limit groove.

[0042] In this embodiment, Figure 4 and Figure 5 The arc-shaped slide groove 11 is symmetrically provided with an arc-shaped support groove 14;

[0043] The support platform 5 is symmetrically fixed with arc-shaped support blocks 53, which slide along the arc-shaped support groove 14, and arc-shaped support plates 54 are provided at two arc-shaped ends of the arc-shaped support block 53 through hydraulic driving sliding;

[0044] Hydraulic telescopic rods 3 55 are symmetrically arranged on both sides of the arc-shaped support block 53 , and springs 2 are arranged on the outer sides of the hydraulic telescopic rods 3 55 . The output end of the hydraulic telescopic rods 3 55 can be pressed against the support groove 14 under the action of the springs 2 .

[0045] In addition, the hydraulic telescopic rod three 55 is an active and passive arc-shaped switching telescopic rod, that is, when the hydraulic telescopic rod three 55 has no hydraulic pressure, the hydraulic telescopic rod three 55 is supported between the support groove 14 and the arc-shaped support block 53 by the spring two, thereby providing a buffer for the support platform 5 when the support platform 5 slides along the vehicle body 1, and after the vehicle body 1 is fixed, the position of the support platform 5 is limited by injecting hydraulic pressure into the hydraulic telescopic rod three 55, thereby keeping the support platform 5 stable during the detection process.

[0046] During implementation, when the vehicle body 1 is offset and bumped, the support platform 5 can slide and deflect along the vehicle body 1, thereby effectively reducing the impact force transmitted from the vehicle body 1 to the lifting mechanism 2, the winch 3 and the detection instrument, ensuring that the lifting mechanism 2, the winch 3 and the detection instrument will not be impacted during transportation. When the vehicle body 1 stops, the support platform 5 can be offset and deflected again under the action of the arc support plate 54 and the hydraulic telescopic rod 3 55, and then the position of the support platform 5 can be further adjusted after the vehicle body 1 is stabilized, so that the support platform 5 remains horizontal, and further enables the lifting mechanism 2 and the winch 3 to maintain a horizontal position in a variety of complex terrains, that is, to ensure that the lifting hoist 24 and the pulley 25 are always aligned with the wellhead, thereby improving the detection stability of the detection instrument.

[0047] To sum up, when the present invention is implemented, the vehicle body 1 is first moved to the oil well that needs to be detected, and then the vehicle body 1 is propped up by the fixed support mechanism 4, and the support heights of the multiple fixed support mechanisms 4 are adjusted according to the inclination of the vehicle body 1 to keep the vehicle body 1 in a horizontal position, and then the lifting mechanism 2 is extended, and the hoisting hoist 24 and the pulley 25 on the lifting mechanism 2 are aligned with the wellhead, and then the lifting mechanism 2 is adjusted to deflect by the deflection adjustment mechanism 6 so that the rolling direction of the pulley 25 is the same as the direction of the oil well, thereby ensuring that no deviation occurs when lowering the cable and the steel wire and effectively reducing the vibration generated by the steel wire and the cable, thereby ensuring the stability of the detection instrument during the detection process and improving the accuracy of the detection results. In the process of vehicle driving, the sliding and deviation of the support platform 5 on the vehicle body 1 effectively reduce the impact on the lifting mechanism 2, the winch 3 and the detection instrument, thereby ensuring the stability of the detection instrument during transportation.

[0048] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
