[0039] Embodiment 1

[0040] In order to solve the problem that the existing technology is prone to cause the pile foundation position inaccurate due to the drilling deviation, the bearing capacity of the pile foundation is reduced, the design requirements cannot be met, the stability of the pile foundation is affected, the pile foundation is prone to tilt or sink, the operation safety of the photovoltaic power station is affected, and / or the installation position of the pile foundation is inaccurate, it is necessary to fill or reinforce around the pile foundation, the installation difficulty and cost are increased. Figures 1-4 As shown in FIG. 1, a pile foundation drilling deviation correction structure is provided, which comprises a T-shaped rotating shaft 3 arranged on a loader 2, a positioning structure 4 arranged on the T-shaped rotating shaft 3, an infrared emitter 5 and an infrared receiver 6 arranged on the positioning structure 4 respectively.

[0041] In practice, the T-shaped rotating shaft 3 is fixed on one side of the loader, and the infrared emitter 5 and the infrared receiver 6 on the positioning structure 4 are located on one side of the auger 1 (such as the drill rod without spiral blades at one end of the motor or the motor). When the auger 1 is corrected, the infrared emitter 5 and the infrared receiver 6 are turned on, and the infrared emitter 5 sends a signal. If the infrared receiver 6 receives the signal or does not receive the signal (the signal receiving condition of the infrared receiver 6 can be fed back to the user, such as the construction personnel), it indicates that the auger 1 deviates and needs to be corrected. At this time, the verticality of the auger 1 needs to be adjusted until the infrared receiver 6 does not receive the signal or receives the signal, and the auger 1 can be used for drilling. The embodiment sets the T-shaped rotating shaft on the loader, sets the positioning structure on the T-shaped rotating shaft, and sets the infrared emitter and the infrared receiver on the opposite positioning structures respectively, which facilitates the detection of whether the auger deviates or the deviation range exceeds the drilling requirement through the cooperation of the infrared emitter and the infrared receiver, so as to adjust the drilling verticality of the auger, avoid the problem that the existing technology is prone to cause the pile foundation position inaccurate due to the drilling deviation, the bearing capacity of the pile foundation is reduced, the design requirements cannot be met, the stability of the pile foundation is affected, the pile foundation is prone to tilt or sink, the operation safety of the photovoltaic power station is affected, and / or the installation position of the pile foundation is inaccurate, it is necessary to fill or reinforce around the pile foundation, the installation difficulty and cost are increased.

[0042] Embodiment 2

[0043] On the basis of embodiment 1, the T-shaped rotating shaft 3 comprises a transverse mounting piece 8 with a mounting hole 7, and a rotating shaft 9 arranged on the mounting piece 8; the positioning structure 4 comprises a sleeve 10 in rotational cooperation with the rotating shaft 9, a positioning telescopic rod 11 connected with the sleeve 10, and a weight 12 arranged on the bottom of the positioning telescopic rod 11; the infrared emitter 5 and the infrared receiver 6 are arranged on the positioning telescopic rod 11. In practice, the positioning structure 4 is in rotational cooperation with the T-shaped rotating shaft 3 through the sleeve 10. Regardless of how the loader 2 drives the auger to rotate along the rotating shaft or the shaft parallel to the rotating shaft, the positioning structure 4 can be driven by the weight to make the positioning telescopic rod 11 perpendicular to the horizontal plane, and the angle of the infrared light emitted or received by the infrared emitter 5 or the infrared receiver 6 arranged on the positioning telescopic rod 11 will not change. Therefore, when the auger 1 is being corrected, the infrared emitter 5 and the infrared receiver 6 can be turned on, and a signal can be sent through the infrared emitter 5. If the infrared receiver 6 receives the signal or does not receive the signal, it indicates that the auger 1 deviates and needs to be corrected. At this time, the perpendicularity of the auger 1 needs to be adjusted until the infrared receiver 6 does not receive the signal or receives the signal, and the auger 1 can be used to drill a hole.

[0044] In practice, the length of the positioning telescopic rod 11 is set according to actual needs. During the drilling process, when the weight is in contact with the ground, the friction between the weight and the ground can be used to effectively prevent the auger 1 from deviating.

[0045] Embodiment 3

[0046] On the basis of embodiment 2, an installation plate 13 is arranged on the positioning telescopic rod 11, and the infrared emitter 5 and the infrared receiver 6 are arranged on the oppositely arranged installation plates 13, respectively. The installation plates 13 are arranged on the sleeve of the positioning telescopic rod, so as to facilitate the installation of the infrared emitter and the infrared receiver. The installation plate 13 is arranged on the sleeve of the positioning telescopic rod, so as to avoid affecting the contraction of the sleeve rod in the sleeve and affecting the drilling.

[0047] Embodiment 4

[0048] On the basis of embodiment 3, two infrared emitters 5 are arranged on the symmetric position of one installation plate 13, and two infrared receivers 6 are arranged on the symmetric position of the other installation plate 13, and the infrared emitters 5 and the infrared receivers 6 on the same side are arranged correspondingly. The two oppositely arranged installation plates are limited to be symmetrically provided with two infrared emitters and two infrared receivers, so as to ensure that the stress on both sides of the positioning telescopic rod is uniform, and facilitate the monitoring of the deviation of the auger through the signal sending and receiving on both sides.

[0049] Embodiment 5

[0050] On the basis of embodiment 4, the infrared emitter 5 and the infrared receiver 6 correspond to the edge side of the drill rod 15 of the auger 1 respectively. The infrared emitter and the infrared receiver correspond to the edge side of the drill rod of the auger respectively, so that the infrared receiver can receive signals on one side or / and both sides after the auger deviates, which facilitates the deviation correction of the auger. For example, when the auger does not deviate, neither of the two infrared receivers 6 can receive signals (the drill rod verticality meets the requirements and the drill rod blocks the emitted signals) or both of the two infrared receivers 6 can receive signals (the drill rod verticality meets the requirements and the drill rod does not block the emitted signals), when the deviation is not large and the drill rod verticality does not meet the requirements, one of the infrared receivers 6 can receive signals and the other one cannot, and when the deviation is large and the drill rod verticality does not meet the requirements, both of the infrared receivers 6 can receive signals.

[0051] Embodiment 6

[0052] On the basis of embodiment 5, when the drill rod 15 of the auger 1 is perpendicular to the horizontal plane, the distance between the position corresponding to the drill rod 15 of the auger 1 and the nearest edge of the drill rod 15 perpendicular to the direction of the emitted or received signals of the infrared emitter 5 and the infrared receiver 6 is less than or equal to the maximum deviation distance. The distance between the position corresponding to the drill rod of the auger and the nearest edge of the drill rod of the infrared emitter and the infrared receiver respectively (for example, the drill rod has left, right, front and back sides, the emitted signals and the received signals of the infrared emitter and the infrared receiver correspond to the left side and the right side of the drill rod respectively, and the distance between the position corresponding to the drill rod of the auger and the nearest edge of the drill rod of the infrared emitter and the infrared receiver respectively refers to the distance between the position points corresponding to the emitted signals and the received signals of the infrared emitter and the infrared receiver and the nearest front or back edge of the drill rod) is less than or equal to the maximum deviation distance (the maximum deviation distance refers to the maximum value of the deviation), for example, the maximum deviation distance is 2 cm, and the distance between the position corresponding to the drill rod of the auger and the nearest edge of the drill rod of the infrared emitter and the infrared receiver respectively cannot exceed two distances, so as to prevent the problem of being unable to correct the deviation and causing the deviation of the drill hole when the distance between the position corresponding to the drill rod of the auger and the nearest edge of the drill rod of the infrared emitter and the infrared receiver respectively is greater than the maximum deviation distance.

[0053] Embodiment 7

[0054] On the basis of embodiment 6, the transparent protective cover 14 for protecting the infrared emitter 5 and the infrared receiver 6 is arranged on the mounting plate 13. The transparent protective cover is arranged to facilitate the dust protection of the infrared emitter and the infrared receiver, so as to avoid affecting the signal emission or reception.
