Description

Technical Field

[0001] This invention belongs to the field of drill pipe docking technology and relates to a drill pipe docking support device. Background Technology

[0002] Deep drilling operations using geological drilling rigs require frequent drill rod extensions. Currently, this process relies entirely on manual operation, lacking a dedicated auxiliary alignment and support mechanism. During the operation, personnel must manually lift the heavy drill rod while simultaneously manipulating the drilling rig drive head to raise and reserve assembly space, manually adjusting the posture to achieve concentric alignment. This method is labor-intensive and costly, and manual alignment makes it difficult to ensure drill rod coaxiality, easily causing problems such as thread wear and borehole deviation. Furthermore, there is a safety hazard of drill rods falling and injuring people, resulting in low operational efficiency and failing to meet the requirements of standardized and efficient construction. Summary of the Invention

[0003] The purpose of this invention is to provide a drill pipe docking support device that can solve the problems mentioned in the background art.

[0004] According to the technical solution provided by the present invention: a drill pipe docking support device includes a base, a first support rod on the base, a limiting component on the first support rod, four first spring telescopic rods on the limiting component, a second connecting block on the first spring telescopic rod, a second support ring on the second connecting block, and a pull rod on the second support ring.

[0005] Preferably, the limiting component includes a crossbar mounted on a first support rod, a first support ring coaxial with a second support ring on the crossbar, three first connecting blocks on the first support ring, and a first spring telescopic rod mounted on the three first connecting blocks and the crossbar.

[0006] Preferably, the other end of the crossbar is provided with a connecting rod, and the lower end of the connecting rod is mounted on the base.

[0007] Preferably, a second support rod is provided on the crossbar, a telescopic rod is provided at the upper end of the second support rod, a support block is provided at the upper end of the telescopic rod, and two support plates are provided on the support block by bolts, with a pressing component being provided on both support plates.

[0008] Preferably, the pressing assembly includes a drill rod, a bearing is fixedly sleeved on the outer side of the drill rod, and the outer side of the bearing is fixedly connected to two support plates; a rectangular telescopic rod is provided at the lower end of the drill rod, a drive concave shaft is provided at the lower end of the rectangular telescopic rod, and a spring is provided between the drive concave shaft and the drill rod, which is sleeved on the outer side of the rectangular telescopic rod; a boss bearing is fixedly sleeved on the outer side of the drive concave shaft, and the upper diameter of the boss bearing is larger than the lower diameter.

[0009] Preferably, the second support rod has two sliding grooves, and a tie rod is provided between the two sliding grooves. A second spring telescopic rod is provided between the tie rod and the second support rod, so that the tie rod moves along the axial direction of the second spring telescopic rod.

[0010] Preferably, the second support ring has a through hole, the lower end of the pull rod is located in the through hole and forms a sliding connection with the through hole, the lower end of the pull rod has an inclined groove, and the upper end of the pull rod contacts the outer wall of the boss bearing.

[0011] The present invention provides a drill pipe docking support device, which has the following advantages:

[0012] 1. By placing the lower end of the drill rod into the second support ring, the lower end of the tie rod supports the drill rod, so that manual lifting is not required when installing the drill rod; then the upper end of the drill rod is connected to the drive shaft for movement, and the drill rod is rotated under the drive of the drill rod.

[0013] When placing the device, position it above the geological borehole. Connect the drill rod in the borehole to a locking connector, which passes through the first support ring, making the locking connector coaxial with the first support ring. As the drill head moves downward, it drives the drill rod connected to the drive shaft downward. Since the lower end of the drill rod abuts against the pull rod, when the drill rod encounters resistance, the upper end of the drill rod abuts against the spring and rectangular telescopic rod, compressing upward. At the same time, the drive shaft and the boss bearing are also compressed and move upward. During the upward movement of the boss bearing, its inclined surface pushes the pull rod to move outward and stretches the second spring telescopic rod. After the pull rod moves outward, the inclined groove of the pull rod no longer bears the load on the drill rod. At this time, the lower end of the drill rod is located inside the second support ring, thus keeping it on the same axis as the locking connector, making the drill rod and the locking connector concentric.

[0020] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0027] Preferably, the pressing assembly includes a drill rod 4, the upper end of which is connected to a drill, and a bearing 41 is fixedly sleeved on the outer side of the drill rod 4. The outer side of the bearing 41 is fixedly connected to two support plates 42. A rectangular telescopic rod 44 is provided at the lower end of the drill rod 4, and a drive shaft 46 is provided at the lower end of the rectangular telescopic rod 44. A spring 45 is sleeved on the outer side of the rectangular telescopic rod 44 between the drive shaft 46 and the drill rod 4. A boss bearing 47 is fixedly sleeved on the outer side of the drive shaft 46, and the upper diameter of the boss bearing 47 is larger than the lower diameter.

[0028] Preferably, the second support rod 14 has two sliding grooves 15, and a pull rod 31 is provided between the two sliding grooves 15. A second spring telescopic rod 3 is provided between the pull rod 31 and the second support rod 14, so that the pull rod 31 moves along the axial direction of the second spring telescopic rod 3; the second spring telescopic rod 3 drives the pull rod to return to its original position.
