Description

Technical Field

[0001] The utility model relates to the technical field of a drilling rig base, in particular to a drilling rig base with a mobile handling structure. Background Technique

[0002] In oil drilling, a drill string is driven to break rocks, drill into the ground, and drill a wellbore of a specified depth for an oil production machine or a gas production machine to obtain oil or natural gas. A common oil drilling rig mainly consists of eight major parts such as a prime mover, a transmission, a working machine, and auxiliary equipment. A base for carrying the drilling rig is provided at the bottom end of the drilling rig.

[0003] The overall weight of the drilling rig is very heavy. When moving and handling the drilling rig, external tools need to be used. However, the bottom end of the drilling rig base is relatively smooth, which makes it difficult for a forklift to find a stable position to lift the base, resulting in inconvenient handling of the drilling rig. Content of the Utility Model

[0004] The purpose of the utility model is to provide a drilling rig base with a mobile handling structure to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A drilling rig base with a mobile handling structure, including a base. Symmetrically arranged lead screws are rotatably connected to the base. Lifting seats are threadedly connected to both of the lead screws. Linking rods are hinged to both of the lifting seats. Load-bearing blocks are symmetrically and fixedly connected to both of the lifting seats. Load-bearing rods are fixedly connected to the base at positions corresponding to the load-bearing blocks at the bottom end of the base. Symmetrically arranged receiving grooves are opened at the middle position of the bottom end of the base. A plurality of symmetrically arranged sliding grooves are opened at the bottom end of the base. Guide rods are fixedly connected to the interiors of the plurality of sliding grooves. Guide blocks are slidably connected to the interiors of the plurality of sliding grooves. Force-applying frames are fixedly connected to the bottom ends of the plurality of guide blocks. Hinge seats are fixedly connected to the opposite sides of the plurality of force-applying frames.

[0006] Preferably, rotating handles are fixedly connected to the top ends of the lead screws. The bottom ends of the lead screws rotatably pass through the base and are threadedly connected to the lifting seats in the receiving grooves.

[0007] Preferably, the bottom ends of the load-bearing rods slidably pass through the load-bearing blocks.

[0008] Preferably, the guide rods are slidably connected to the guide blocks, and the force-applying frames are all located at the bottom ends of the sliding grooves.

[0009] Preferably, the remote ends of the top sides of the inclined sides of the linking rods are hinged to the hinge seats.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows: When carrying the drilling machine, the forklift can insert the fork into the interior of each force-applying frame, so that the forklift can stably lift the drilling machine and the base. And through the interlocking cooperation of each mechanism, the distance between each force-applying frame can be adjusted, so that each force-applying frame can be applicable to forklifts with different fork distances. The present utility model can improve the handling and moving convenience of the base and the drilling machine, and each force-applying frame has strong applicability, with strong practicability. Moreover, the structure of the present utility model is simple, and both the manufacturing cost and the use cost are relatively low, which is worthy of popularization and use.

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] Please refer to Figures 1-4, the present utility model provides a technical solution: a drilling rig base with a mobile handling structure, including a base 1, on which symmetrically arranged lead screws 2 are rotatably connected. Both lead screws 2 are threadedly connected with lifting seats 3. On both lifting seats 3, linkage rods 4 are hinged. On both lifting seats 3, symmetrically arranged bearing blocks 5 are fixedly connected. At the positions corresponding to the bearing blocks 5 at the bottom end of the base 1, bearing rods 6 are fixedly connected. At the middle position of the bottom end of the base 1, symmetrically arranged receiving grooves 7 are opened. At the bottom end of the base 1, symmetrically arranged multiple sliding grooves 8 are opened. Inside each of the multiple sliding grooves 8, a guide rod 9 is fixedly connected. Inside each of the multiple sliding grooves 8, a guide block 10 is slidably connected. At the bottom ends of the multiple guide blocks 10, force - borrowing frames 11 are fixedly connected. On the opposite sides of the multiple force - borrowing frames 11, hinge seats 12 are fixedly connected.

[0018] Further, at the top ends of the lead screws 2, turning handles 13 are fixedly connected. At the bottom ends of the lead screws 2, they rotatably pass through the base 1 and are threadedly connected with the lifting seats 3 in the receiving grooves 7. The turning handles 13 facilitate the rotation of the lead screws 2.

[0019] Further, at the bottom ends of the bearing rods 6, they slidably pass through the bearing blocks 5. The bearing rods 6 facilitate guiding the movement of the bearing blocks 5, and the bearing rods 6 and the bearing blocks 5 are convenient for bearing the pressure of the lifting seats 3, hinge seats 12 and linkage rods 4.

[0020] Further, the guide rods 9 are all slidably connected with the guide blocks 10. The force - borrowing frames 11 are all located at the bottom ends of the sliding grooves 8. The guide rods 9 facilitate guiding the movement of the guide blocks 10.

[0021] Further, at the diagonally - away ends at the top of the linkage rods 4, they are all hinged with the hinge seats 12.

[0022] Specifically, when using the present utility model, when using a forklift with a relatively small fork spacing, first rotate the lead screw 2 through the turning handle 13. The rotation of the lead screw 2 will drive the lifting seat 3 to move downward. The downward movement of the lifting seat 3 will drive the bearing block 5 to move downward. At the same time, the downward movement of the lifting seat 3 will also pull the linkage rod 4. The pulled linkage rod 4 will rotate around the connection with the lifting seat 3 as the center. At this time, at the connection of each linkage rod 4 and the lifting seat 3, it will not only move downward but also rotate upward around the lifting seat 3. At this time, when each linkage rod 4 rotates upward simultaneously, it will act on the hinge seat 12. The hinge seats 12 will drive the force - borrowing frames 11 to move towards the middle direction. The movement of the force - borrowing frames 11 towards the middle direction will drive the guide blocks 10 to slide inside the sliding grooves 8. The guide rods 9 will guide the movement of the guide blocks 10. Move each force - borrowing frame 11 to the specified position. At this time, the forklift can insert the forks into the inside of each force - borrowing frame 11, and lift the base 1 through the force - borrowing frames 11 for movement. The force borne by the force - borrowing frames 11 will be dispersed to the hinge seats 12, linkage rods 4, lifting seats 3, lead screws 2, bearing blocks 5 and bearing rods 6, and be jointly borne by each mechanism.

[0023] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
