[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0019] Example 1, as Figures 1-2 As shown, a conveyor wheel structure for a vertical lifting material turning auxiliary machine for a pipe thread lathe includes a mounting frame 1. A hinge shaft 2 is rotatably connected above the mounting frame 1 via a bearing seat. The hinge shaft 2 is connected to the drive end of a drive mechanism, which drives the hinge shaft 2 to rotate.

[0020] A first rocker arm 3 and a second rocker arm 4 are fixedly connected to the outer surface of the hinge shaft 2. The first rocker arm 3 and the second rocker arm 4 are arranged parallel to each other. A rotary motor reducer 5 is fixedly installed on the outer side of the first rocker arm 3. The output shaft of the rotary motor reducer 5 passes through the first rocker arm 3 and the second rocker arm 4 in sequence and is connected to the first rocker arm 3 and the second rocker arm 4 through bearings. A roller 6 is arranged between the first rocker arm 3 and the second rocker arm 4. The roller 6 is fixedly installed on the outer surface of the output shaft of the rotary motor reducer 5. A V-groove 7 is surrounded on the outer surface of the roller 6.

[0021] A semi-conical ring 8 is fixedly installed at the outer end of the second rocker arm 4, and the outer surface of the semi-conical ring 8 smoothly transitions with the inclined surface of the V-groove 7.

[0022] Working principle:

[0023] Taking oil drill pipe as an example, when it is necessary to support and transport the oil drill pipe, the drive end of the drive mechanism can be controlled to drive the hinge 2 to rotate counterclockwise. Then, the first rocker arm 3 and the second rocker arm 4 on the outer surface of the hinge 2 will rotate upward synchronously, so as to drive the roller 6 between the first rocker arm 3 and the second rocker arm 4 to move upward to a suitable height. The V-groove 7 surrounding the outer surface of the roller 6 will achieve the support effect for the drill pipe. Then, the rotation motor reducer 5 will be controlled to run, and the output shaft of the rotation motor reducer 5 will drive the roller 6 to rotate, thereby driving the pipe to move forward along its axial direction to the corresponding position in the lathe spindle hole.

[0024] In this embodiment, by fixing a semi-conical ring 8 on the outer end of the second rocker arm 4, the axial direction of the semi-conical ring 8 is parallel to the axial direction of the drum 6, so that the semi-conical ring 8 can move up and down synchronously with the second rocker arm 4 and the drum 6. Therefore, the opening area of the V-shaped groove 7 can be effectively increased without increasing the length of the drum 6 itself. When the oil drill rod with a larger diameter is used, the semi-conical ring 8 on the outer edge of the second rocker arm 4 can effectively intercept the large-diameter oil drill rod, so that the drill rod falls on the conical surface of the semi-conical ring 8. Then, the smooth transition effect of the semi-conical ring 8 and the inclined surface of the V-shaped groove 7 allows the oil drill rod to finally roll into the middle position of the V-shaped groove 7. In addition, when the lathe auxiliary machine transfers the oil drill rod along the radial direction of the oil drill rod, even if the oil drill rod is skewed forward and backward, the semi-conical ring 8 can make the skewed part of the oil drill rod fall on the conical surface of the semi-conical ring 8, and then the smooth transition effect of the outer surface of the semi-conical ring 8 and the inclined surface of the V-shaped groove 7 can make the oil drill rod roll again along the outer conical surface of the semi-conical ring 8 and the inclined surface of the V-shaped groove 7 to the middle position of the V-shaped groove 7.

[0025] In the second embodiment, as a further preferred solution of the first embodiment, the first rocker arm 3 and the second rocker arm 4 each include a connecting rocker arm and a supporting rocker arm, one end of the connecting rocker arm is fixedly welded to the outer surface of the hinge shaft 2, the other end of the connecting rocker arm is connected and fixed to the supporting rocker arm through locking bolts, and the output shaft of the rotating motor reducer 5 passes through the two supporting rocker arms and is connected to the two supporting rocker arms through bearings. Therefore, when the entire drum 6 and the rotating motor reducer 5 need to be disassembled for maintenance, only the locking bolts need to be removed to separate the connecting rocker arm and the supporting rocker arm. The entire conveying wheel structure does not need to be disassembled, thus greatly simplifying the disassembly and assembly work of the drum 6 and the rotating motor reducer 5. In turn, the maintenance efficiency of the device is effectively improved.

[0026] In the third embodiment, as a further preferred solution of the first embodiment, the driving mechanism includes a telescopic cylinder, the telescopic cylinder is connected to one end of a driving rod through a piston rod, the other end of the driving rod is connected to one end of a connecting rod 9 through a pin shaft, and the other end of the connecting rod 9 is fixedly welded to the outer surface of the hinge shaft 2.

[0027] Therefore, when the hinge shaft 2 is controlled to rotate, the piston rod of the telescopic cylinder can be controlled to extend or retract, and then the driving rod drives one end of the connecting rod 9 to move forward and backward. Since one end of the connecting rod 9 is connected to the driving rod through the pin shaft, and the other end of the connecting rod 9 is fixedly welded to the hinge shaft 2, the connecting rod 11 and the hinge shaft 2 can be driven to rotate synchronously around the axis of the hinge shaft 2 through the lever principle by moving the one end of the connecting rod 9 forward and backward.

[0028] The above examples are only used to illustrate the technical solutions of the present application, and are not intended to limit them; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that the technical solutions recorded in the foregoing examples can still be modified, or some technical features therein can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
