[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] The utility model provides a goose head frame for a rotary drilling rig, such as Figures 1 to 6 shown.

[0034] Example 1:

[0035] A goose head frame for a rotary drilling rig includes a frame 1, the frame 1 is a hollow structure, and a goose head body 2 is installed on the upper end of the frame 1, a folding assembly is installed between the goose head body 2 and the frame 1, the folding assembly is located on the side of the frame 1, and can slide along the long side of the frame 1. The folding assembly can drive the goose head body 2 to rotate on the frame 1, thereby controlling the angle between the goose head body 2 and the frame 1, so that the goose head body 2 is in a working state. At this time, the goose head body 2 is perpendicular to the long side of the frame 1 (such as Figure 1 ), or parallel to the long side of the frame 1 (as shown Figure 2As shown), at this time, the goose head body 2 can be slid downward, so that the goose head body 2 is stored inside the frame 1 (as shown in FIG. Figure 3 It can reduce the volume and facilitate transportation and storage when not in use.

[0036] The folding assembly includes a fixed shaft 3, which is fixedly connected to the goose head body 2, and both ends of the fixed shaft 3 extend to the outside of the frame 1 through the through grooves 4 provided on both side surfaces of the frame 1. The end of the fixed shaft 3 is rotatably installed with a sliding seat 5, which is slidably installed on the side of the frame 1 and is driven by a telescopic oil cylinder 16 installed on the side of the frame 1.

[0037] A rotary oil cylinder 6 is installed on the sliding seat 5. A driving gear 8 is fixedly connected to the output rod of the rotary oil cylinder 6. A driven gear 7 is fixedly connected to the end face of the fixed shaft 3. The driving gear 8 and the driven gear 7 are meshed and connected. The rotation of the output rod of the rotary oil cylinder 6 will drive the goose head body 2 to rotate through the driving gear 8 and the driven gear 7, thereby controlling the angle of the goose head body 2.

[0038] A support rod 14 is fixedly connected to the inside of the frame 1. When the goose head body 2 is in working condition, the support rod 14 is close to the side of the weight hanging point of the goose head body 2, which can support the goose head body 2 from below, so that the goose head body 2 can work stably.

[0039] Example 2:

[0040] On the basis of Example 1, in order to keep the goose head body 2 in a stable working state or folded state, a limiting part is further provided on the sliding seat 5. When the rotary cylinder 6 is started, the limiting part is disengaged from the driven gear 7, so that the rotary cylinder 6 can smoothly drive the goose head body 2 to rotate. When the rotary cylinder 6 is closed, the limiting part and the driven gear 7 are engaged with each other, so that the angle of the goose head body 2 can be kept stable, so that the goose head body 2 can be stably kept in a working state or a folded state.

[0041] The limiting part includes a base frame 15, which is fixedly connected to the sliding seat 5, and a gear rod 9 is slidably installed at the opening of the base frame 15. The gear rod 9 is fixedly connected to a fixed frame 10 on one side surface inside the base frame 15, and a fixing rod 11 is inserted into the inside of the fixed frame 10. Both ends of the fixing rod 11 are fixedly connected to the inner side wall of the base frame 15, and a spring 12 is connected between the fixing rod 11 and the gear rod 9. One end of the spring 12 is fixedly connected to the fixing rod 11, and the other end is fixedly connected to the gear rod 9. The spring 12 has an elastic force to push the gear rod 9 toward the driven gear 7, so that the gear rod 9 can be stably engaged with the driven gear 7 without external force, and the fixed frame 10 and the fixing rod 11 can limit the gear rod 9, so that the gear rod 9 can slide stably inside the base frame 15.

[0042] The oil inlet pipe 13 of the rotary cylinder 6 passes through the fixed frame 10 and is fixedly connected to the lower side of the fixed rod 11. When the rotary cylinder 6 is working, the external oil will enter the interior of the rotary cylinder 6 through the oil inlet pipe 13. At this time, the oil inlet pipe 13 will expand, thereby pushing the fixed frame 10 toward the inside of the base frame 15, and then the gear rod 9 can overcome the elastic force of the spring 12 and move away from the driven gear 7, disengaging from the driven gear 7, so that the rotary cylinder 6 can smoothly drive the goose head body 2 to rotate.

[0043] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
