Description

Technical Field

[0001] The invention relates to the technical field of oil drilling tool transport equipment, in particular to a horizontal drilling tool grabbing device for oil drilling rigs. Background Art

[0002] The drill string gripper is a key component of the drill string discharge system, working in conjunction with the drill pipe box and the crane that transports the drill pipe. Using a pre-set control program, the device facilitates the transport of drilling tools, such as drill pipe, drill collars, and casing, between the drill pipe box and the catwalk, effectively improving the speed, efficiency, and stability of drilling operations while significantly enhancing safety and reliability. It is an essential component of the drilling system.

[0003] Most similar drill tool gripper devices currently in practical use use electromagnets as their core actuators, and are primarily driven by hydraulic cylinders, hydraulic winches, or electric winches. These drive structures enable the devices to perform basic operations such as gripping, lifting, and lowering drill tools. These devices meet basic operational requirements in conventional drilling scenarios, ensuring the orderly conduct of drilling operations. However, the structural design of the existing drill tool gripper device has many shortcomings. For example, the operating accuracy is difficult to meet the requirements of high-precision drilling, the impact during operation is large, and the hydraulic drive device is prone to leakage. At the same time, the overall size of the device is relatively large, which not only increases the difficulty of installation but also affects the convenience of transportation. Especially when dealing with larger-sized drill tools, its scope of application and operating capacity have obvious limitations, and it is difficult to adapt to complex drilling conditions.

Its core frame consists of two parallel traveling beams 1 and tracks 2 erected thereon, providing the main moving path and support foundation for the device. The crossbeam 3, as the key load-bearing and moving component, spans between the two traveling beams 1 and is connected to the upper structure through a movable fixed shell 7. Multiple groups of electromagnet columns 4 are symmetrically distributed at both ends of the crossbeam 3. They serve as direct actuators and are responsible for generating adsorption force to grab the drilling tools.

Each unit includes a fixed cylinder 66 vertically fixed on the mounting plate 62.

By independently adjusting the magnetic force generated by the electromagnets at the four corners through electric control, the extension of the four connecting rods 68 can be accurately controlled, thereby pushing the adjustment plate 63 to produce the required tilt angle and realizing universal adjustment of the electromagnet column 4.

[0029] Example 3: Please refer to Figures 8-10 The present invention provides a technical solution: the anti-sway auxiliary guide mechanism 5 includes an electric telescopic rod 51 arranged at the bottom of the mounting beam 12, and a lifting clamp 53 is provided at the bottom end of the electric telescopic rod 51. Two special-shaped rods 56 are movably provided on the inner side of the lifting clamp 53, and the sides of the two special-shaped rods 56 are provided with mobile clamps 54. The inside of the two mobile clamps 54 are rotatably provided with moving rollers 52, and their telescopic movement provides the initial lifting power of the entire anti-sway mechanism. The end of the piston rod of the electric telescopic rod 51 is connected to a lifting clamp 53, and a pair of special-shaped rods 56 are hinged to the lifting clamp 53 through a guide rod 59, and can rotate around the hinge point within a certain angle range.

[0030] A guide rod 59 movably connected to the lifting clamp 53 is provided inside the special-shaped rod 56. A groove 511 is provided on the outside of the special-shaped rod 56. A torsion spring 510 is sleeved on the outside of the guide rod 59. The two ends of the torsion spring 510 are respectively arranged on the lifting clamp 53 and the inner side of the groove 511. The torsion spring 510 is sleeved on the guide rod 59, and its two ends act on the lifting clamp 53 and the groove 511 of the special-shaped rod 56 respectively, providing an inward reset torque for the special-shaped rod 56, so that it has a tendency to automatically clamp. A movable clamp 54 is installed on the outside of each special-shaped rod 56, and freely rotatable movable rollers 52 are embedded in it. These rollers are in direct contact with the surface of the drilling tool.

[0031] A rotating plate 512 is provided on the outer side of the two special-shaped rods 56, a straight rod 513 is provided between the two rotating plates 512, a wedge 58 is movably provided between the sides of the two rotating plates 512, a threaded rod 57 connected to the internal thread of the lifting clamp 53 is provided on the side of the wedge 58, a rotating disk 55 is provided at the end of the threaded rod 57, the wedge 58 is screwed into and connected to the threaded rod 57, and the threaded rod 57 is driven forward and backward by rotating the rotating disk 55, so as to precisely adjust the depth of the wedge 58 inserted between the two rotating plates 512.

[0032] Working principle: When using this device, first move the fixed shell 7 and the electromagnet column 4 so that the outer load-bearing roller 14 slides inside the traveling beam 1 and the track 2. After sliding to the working position, the fixed shell 7 and the electromagnet column 4 are locked. At this time, the electromagnet column 4 and the crossbeam 3 are in a high position. It is necessary to start the lifting electric cylinder 85. The lifting electric cylinder 85 begins to shrink, which will drive the moving pulley 86 at the end to retract. At this time, the wire rope 82 outside the moving pulley 86 will reduce its expansion, so that the crossbeam 3 is on the guide column. Under the action of the second 11 and the guide column 9, the electromagnet column 4 is moved to the outside of the drilling tool that needs to be transferred. At the same time, the electric telescopic rod 51 will drive the lifting clamp 53 to descend, and the moving roller 52 will contact the outside of the drilling tool, first flip inward, pass over the drilling tool and then reset. At this time, the two moving rollers 52 will be stuck on the outside of the drilling tool. When it wants to expand, the rotating plate 512 will rotate, and under the action of the wedge block 58, the two rotating plates 512 cannot flip outward, thereby achieving an auxiliary effect; At this time, the electromagnet column 4 is energized to absorb the drilling tool, and the lifting electric cylinder 85 extends. The lifting electric cylinder 85 drives the movable pulley 86 to move horizontally, causing the wire rope 82 to expand, thereby driving the crossbeam 3 to rise, causing the electromagnet column 4 to drive the drilling tool to rise, thereby completing the work of the drilling tool; When it is necessary to deal with the outer surfaces of different drilling tools, it is necessary to control the electromagnetic control component 612 through the electric main control device 65 and the wire 614, so that the electromagnetic control component 612 adjusts the current size of the electromagnet 2 613, so that the distance between the electromagnet 2 613 and the electromagnet 1 611 changes. At this time, the adjustment columns 64 at the four corners of the adjustment plate 63 change and rotate on the outer surface of the movable ball 67, thereby completing the angle adjustment of the electromagnet column 4 so that it can adsorb the outer surface of the special-shaped drilling tool.
