Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figure 1-Figure 3 The utility model provides an automatic positioning device for a rotary table of a rotary drilling rig: it includes a processing table 1, two mounting side plates 2 are fixedly installed on the upper surface of the processing table 1, the side walls of the two mounting side plates 2 are penetrated and rotatably connected with a rotating mounting shaft 3, and the side walls of the mounting side plates 2 are installed with a driving mechanism for driving the rotating mounting shaft 3; the driving mechanism includes a driving motor 8 fixedly installed on the side walls of the mounting side plates 2, the driving end of the driving motor 8 is fixedly connected with a driving shaft 9, the end of the rotating mounting shaft 3 is fixedly connected with a movable shaft 10, and the outer surfaces of the driving shaft 9 and the movable shaft 10 are fixedly sleeved with pulleys 11, and the two pulleys 11 are connected through a transmission belt 12.

[0026] Among them, the two rotating mounting shafts 3 are fixedly connected to the opposite ends with a positioning clamping assembly; the positioning clamping assembly includes a connecting plate 13 fixedly installed on the end of the rotating mounting shaft 3, the outer wall of the connecting plate 13 is fixedly connected to a horizontally arranged driving cylinder three 14, and the piston end of the driving cylinder three 14 is fixedly connected to an arc-shaped clamping plate 15, and the two arc-shaped clamping plates 15 are arranged opposite to each other so as to better fit with the side of the rotary table of the rotary drilling rig.

[0027] Among them, a plurality of supporting push rods 4 are penetrated and slidably connected to the upper surface of the processing table 1, and an adjusting mechanism for adjusting the upper and lower positions of the plurality of supporting push rods 4 is fixedly connected to the lower surface of the processing table 1. The adjusting mechanism includes a driving cylinder 1 5 fixedly installed on the lower surface of the processing table 1, and the piston end of the driving cylinder 1 5 is arranged downward and fixedly connected to a movable mounting plate 6. A plurality of driving cylinders 2 7 corresponding to the plurality of supporting push rods 4 are fixedly connected to the upper surface of the movable mounting plate 6, and the piston end of the driving cylinder 2 7 is fixedly connected to the bottom of the corresponding supporting push rod 4. A driving cylinder 4 1 is fixedly installed at the center of the upper surface of the processing table 1. 6. An arc-shaped positioning plate 17 is fixedly installed on the top piston end of the driving cylinder four 16, and multiple supporting top rods 4 are arranged in a circular array with the arc-shaped positioning plate 17 as the center. It should be noted that when the driving cylinder one 5 drives the movable mounting plate 6 to move, the movable mounting plate 6 moves to drive the multiple supporting top rods 4 to move up or down synchronously, so as to achieve the purpose of synchronously adjusting the positions of the multiple supporting top rods 4, and the driving cylinder two 7 corresponding to the supporting top rods 4 one by one can be used to control the height of the corresponding supporting top rod 4, so that different supporting top rods 4 can better support the uneven surface on the turntable of the rotary drilling rig.

[0028] The functional principle of the utility model can be explained through the following operation modes:

[0029] First, place the rotary drilling rig turntable to be processed on the top of multiple supporting top rods 4, and then synchronously start the driving cylinders 3 14 on both sides of the rotary drilling rig turntable. The piston ends of the driving cylinders 3 14 push the corresponding arc-shaped clamping plates 15 to move. The two arc-shaped clamping plates 15 move relative to each other until the side of the rotary drilling rig turntable is clamped, so that the horizontally placed rotary drilling rig turntable can be clamped and positioned.

[0030] When the rotary drilling rig turntable needs to be flipped, the driving cylinder 1 5 is started to drive the movable mounting plate 6 to move downward, and the movable mounting plate 6 can drive the driving cylinder 2 7 and the supporting top rod 4 to move downward as a whole, and the supporting top rod 4 is gradually separated from the rotary drilling rig turntable, providing space for the flipping of the rotary drilling rig turntable, and then the driving motor 8 is started, and the driving motor 8 drives the driving shaft 9 to rotate, and the driving shaft 9 drives the movable shaft 10 to rotate through the transmission belt 12, and the movable shaft 10 then drives the driving cylinder 3 14 and the arc clamping plate 15 to rotate as a whole through the rotating mounting shaft 3, that is, the rotary drilling rig turntable starts to rotate.

[0031] When the rotary drilling rig turntable is rotated and adjusted to a vertical state, the driving cylinder four 16 can also be started, and the piston end of the driving cylinder four 16 pushes the arc-shaped positioning plate 17 to move upward. The upward arc-shaped positioning plate 17 can fit with the bottom surface of the rotary drilling rig turntable, further support the rotary drilling rig turntable, and ensure the stability of the rotary drilling rig turntable. When the rotary drilling rig turntable needs to be flipped again, the piston end of the driving cylinder four 16 pulls the arc-shaped positioning plate 17 downward. After the arc-shaped positioning plate 17 is separated from the rotary drilling rig turntable, the rotary drilling rig turntable can start to rotate and adjust again.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
