Among them, when the first locking mechanism 151 is in the locking state, the first section mast 11 and the second section mast 12 are rigidly connected, and when the first locking mechanism 151 is in the unlocking state, the second section mast 12 can rotate in the vertical direction relative to the first section mast 11.
[0026] The utility model discloses a mast structure 10 is divided into first section mast 11 and second section mast 12, one end of first section mast 11 and one end of second section mast 12 are connected through first pivot mechanism 141 and can rotate in vertical direction, and the rotation state between first section mast 11 and second section mast 12 is controlled through first locking mechanism 151 again, when needing work, can rotate first section mast 11 and second section mast 12 to a straight line and lock through first locking mechanism 151, when needing transportation, can fold up first section mast 11 and second section mast 12, thereby reduce the volume, to reduce the expense when transporting.
[0027] Further, the rotation angle between the second section mast 12 and the first section mast 11 is 0°~90°, when needing work, the first section mast 11 and the second section mast 12 are rotated to a straight line, at this time, the rotation angle between the second section mast 12 and the first section mast 11 is 0°; when needing transportation, the rotation angle between the first section mast 11 and the second section mast 12 is 90°, at this time, the first section mast 11 and the second section mast 12 are perpendicular to each other.
[0028] Optionally, the length of the second section mast 12 is equal to the height of the first section mast 11 from the ground in the transportation state. When needing transportation, the second section mast 12 is rotated downward by 90° relative to the first section mast 11, the first section mast 11 is in a flat lying state, and the second section mast 12 is in a vertical state, so that the second section mast 12 can support the first section mast 11.
[0029] Further, the first pivot mechanism 141 is located on the lower side of the first section mast 11 and the second section mast 12, so that the first pivot mechanism 141 can be directly welded on the lower surface of the first section mast 11 and the second section mast 12, facilitating processing and manufacturing; and the abutting surface between the first section mast 11 and the second section mast 12 can also be directly set as a plane, reducing the processing difficulty.
[0030] In the embodiment, the mast structure 10 includes a support rod 16, the first section mast 11 is provided with a first support seat 111, the second section mast 12 is provided with a second support seat 121, one end of the support rod 16 is detachably connected with the first support seat 111, and the other end of the support rod 16 is detachably connected with the second support seat 121. When needing transportation, the second section mast 12 is rotated downward by 90° relative to the first section mast 11, and the two ends of the support rod 16 are matched with the first support seat 111 and the second support seat 121 respectively, so as to limit the rotation angle between the second section mast 12 and the first section mast 11, thereby supporting the second section mast 12 and the first section mast 11.
[0031] In this embodiment, the mast structure 10 comprises a third section mast 13, a second pivot mechanism 142 and a second locking mechanism 152. One end of the third section mast 13 is connected to the second section mast 12 away from the first section mast 11 through the second pivot mechanism 142 and the second locking mechanism 152. In the locked state, the second locking mechanism 152 is rigidly connected between the third section mast 13 and the second section mast 12; in the unlocked state, the third section mast 13 can rotate relative to the second section mast 12. By dividing the mast structure 10 into the first section mast 11, the second section mast 12 and the third section mast 13, the volume during transportation can be further reduced. The first locking mechanism 151 and the second locking mechanism 152 can be bolts, which are manually disassembled to control the locked state and the unlocked state of the locking mechanism. Of course, in other embodiments, quick-release locking mechanisms or latches can also be used.
[0032] Further, the rotation angle between the third section mast 13 and the second section mast 12 is 0°~180°. When working, the third section mast 13 and the second section mast 12 are rotated to a straight line, and the rotation angle between the third section mast 13 and the second section mast 12 is 0°; when transporting, the rotation angle between the third section mast 13 and the second section mast 12 is 180°, and the third section mast 13 and the second section mast 12 are located on two parallel straight lines, so as to facilitate transportation.

In this embodiment, the third section mast 13 can rotate relative to the second section mast 12 in the horizontal direction, for example, forward and backward. Of course, the third section mast 13 can rotate relative to the second section mast 12 in the vertical direction, for example, up and down.
[0034] Further, the length of the third section mast 13 and the height of the anchor bracket 24 are equal to the height of the first section mast 11 from the ground in the transportation state. Thus, under the premise of ensuring that the mast structure 10 has a longer unfolded length, the volume of the mast structure 10 during transportation is reduced.
[0035] The application also provides a rotary drilling rig, which comprises a main machine 21, a power head 22, an amplitude changing mechanism 23, an anchor hanging frame 24, a drill rod (not shown in the figure) and the mast structure 10 as described above.

A winch system (not shown in the figure) on the main machine 21 is connected with the drill rod through a rope around the anchor hanging frame 24, so as to control the lifting of the drill rod, and one end of the drill rod is connected with a drilling tool. Among them, the drill rod is usually needed to be disassembled during transportation, so it is not shown in the figure.
[0036] When the rotary drilling rig is transported, the third section mast 13 is rotated 180° backward relative to the second section mast 12, so that the third section mast 13 is folded together with the second section mast 12, as shown in Figure 2 Then, the second section mast 12 is rotated 90° downward relative to the first section mast 11, and the two ends of the support rod 16 are used to cooperate with the first support seat 111 and the second support seat 121 respectively, so as to limit the rotation angle between the second section mast 12 and the first section mast 11, thereby supporting the second section mast 12 and the first section mast 11, as shown in Figure 3 Among them, during transportation, the first pivot mechanism 141 and the second locking mechanism 152 need to be adjusted to the unlocked state, that is, the bolts connecting the second section mast 12 and the first section mast 11 and the bolts connecting the third section mast 13 and the second section mast 12 are disassembled.
