Description

Technical Field

[0001] This utility model relates to the field of geological drilling technology, and in particular to a rope connection assembly for traction of drill rods in drilling rigs. Background Technology

[0002] Geological drilling is a geological exploration method that uses specialized drilling equipment and techniques to drill holes in the Earth's crustal rock layers in order to obtain information about underground rocks, soil, hydrogeology, etc. During the drilling process, a drilling rig is used to drill drill rods and drill bits into the ground. By continuously adding drill rods, the drill bit can be drilled hundreds of meters underground. Subsequently, the underground rock and soil layer structure is obtained through retrieval.

[0003] Existing drill pipe retrieval methods require the use of a retrieval device. During retrieval, a rope needs to be connected to the top of the retrieval device. Then, the retrieval device is lowered into the borehole using a motor and reel inside the drilling rig. Once the retrieval device descends to the position of the drill pipe in the borehole, it is locked in place by engaging with the top of the drill pipe. The retrieval device and the drill pipe are then lifted by the rope, thus achieving the effect of pulling the drill pipe upward.

[0004] In existing geological drilling operations, when retrieving drill pipes, a rope needs to be threaded through a hole at the top of the retrieval device for connection. The retrieval device then pulls the drill pipes for retrieval. However, this method of connecting the rope through a round hole alone has the problem of insufficient stability. When retrieving the retrieval device, the connection end between the retrieval device and the rope will swing, affecting the retrieval efficiency and making it inconvenient to use.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] Example 1

[0029] Reference Figure 1 , Figure 2 and Figure 3 This is the first embodiment of the present invention. This embodiment provides a rope connection assembly for traction of drill rods on drilling rigs, including a retrieval device body 1. A locking assembly 2 is provided at the top of the retrieval device body 1, and a clamping assembly 3 is provided above the locking assembly 2. The locking assembly 2 includes two fixing blocks 202 fixedly connected to the top of the retrieval device body 1. A rotating plate 201 is hinged to the outer surface of the fixing block 202. A threaded sleeve 203 is movably connected inside the fixing block 202. A threaded shaft 208 is threadedly connected inside the threaded sleeve 203.

[0030] Specifically, each of the two fixed blocks 202 has a groove on one of its adjacent sides. The rotating plate 201 is hinged to the inside of the groove by a pin. A torsion spring is provided at the part of the rotating plate 201 that is hinged to the inner wall of the groove by the pin. A rectangular opening is provided inside the rotating plate 201. The rotating block 206 is fixedly connected to the outer surface of the threaded sleeve 203 away from the fixed block 202. The mounting plate 205 is fixedly connected to the end of the threaded shaft 208 away from the fixed block 202. The insertion rod 204 is fixedly connected to the side of the mounting plate 205 near the fixed block 202. The fixed block 202 has an insertion hole that mates with the insertion rod 204. A locking plate 207 is fixedly connected to the adjacent side of the two fixed blocks 202. One of the threaded shafts 208 has a circular protrusion at the end away from the threaded sleeve 203, and the other threaded shaft 208 has an insertion hole that mates with the circular protrusion at the end near the circular protrusion.

[0031] Furthermore, by rotating and opening the connecting block 303 and the limiting block 304, the bottom rotating plate 201 is exposed. Then, the ring at the rope connection end is inserted between the two fixing blocks 202, causing the rotating plate 201 to rotate downwards. After the ring at the rope connection end passes through, the rotating plate 201 is reset under the action of the torsion spring. Then, the rotating block 206 is turned by a wrench or other tools. The rotating block 206 drives the threaded shaft 208 to insert inward through the threaded sleeve 203, so that the threaded shaft 208 is inserted into the ring at the rope connection end, thereby further locking the rope connection end. By setting the locking plate 207, the maximum rotation of the rotating plate 201 to the horizontal position can be limited, thereby ensuring that the rope can be restricted below the rotating plate 201, thus achieving the locking effect. The existing rope connection end is set as a ring or hook. The connection relationship between the rope and other components, the working principle and the operation sequence are existing technologies and are common knowledge known to those skilled in the art, and will not be elaborated on here.

[0032] Example 2

[0033] Reference Figure 1, Figure 2 , Figure 4 and Figure 5 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The clamping component 3 includes a connecting block 303 hinged to the upper surface of one of the fixing blocks 202, and a locking block 306 hinged to the upper surface of the other fixing block 202. Two abutting blocks 302 are fixedly connected to the side of the connecting block 303 near the locking block 306. Two locking blocks 301 are fixedly connected to the side of the abutting block 302 near the locking block 306. A limiting plate 305 that cooperates with the locking blocks 301 is slidably disposed inside the locking block 306.

[0034] Specifically, the locking block 306 has a rectangular through groove on the side near the locking block 301 that cooperates with the locking block 301. The locking block 306 has a sliding groove inside. The limiting plate 305 is slidably disposed inside the sliding groove. The upper surface of the limiting plate 305 is fixedly connected to the limiting block 304. The upper surface of the inner wall of the sliding groove has a limiting groove that cooperates with the limiting block 304. A compression spring 307 is fixedly connected between the two limiting plates 305. Several soft extrusion blocks are provided on the adjacent surfaces of the two abutting blocks 302.

[0035] Furthermore, when rotating the connecting block 303, the abutment block 302 drives the locking block 301 to insert into the rectangular through groove on the outer surface of the locking block 306. During insertion, the two limiting plates 305 need to be pressed into the locking block 306. After the locking block 301 is inserted, the limiting plates 305 are released. Under the reset action of the compression spring 307, the limiting plates 305 lock the locking block 301, thereby locking the abutment block 302 and the rotating block 20 by restricting the movement of the locking block 301. 6. Then, the soft abutment block 302 on the outer surface of the abutment block 302 abuts against the outer surface of the rope, thereby preventing the rope connection end from shaking. The length of the limiting groove opened on the inner wall of the sliding groove inside the locking block 306 can ensure that the limiting block 304 drives the limiting plate 305 to stay inside the locking block 306 without protruding out of the locking block 306, thereby ensuring that the limiting plate 305 will not protrude out and contact the inner wall of the borehole, and preventing the limiting plate 305 from affecting the movement of the retrieval device body 1 inside the borehole.

[0036] Working principle: When traction and retrieval of the drill rod, the connecting block 303 and the limiting block 304 are rotated to open, exposing the bottom rotating plate 201. Then, the ring at the rope connection end is inserted between the two fixing blocks 202, causing the rotating plate 201 to rotate downwards. After the ring at the rope connection end passes through, the rotating plate 201 is reset under the action of the torsion spring. The locking plate 207 restricts the rotating plate 201 to a horizontal position, thus fixing the rope connection end inside the fixing block 202. Then, the rotating block 206 is moved by a wrench or other tools. The rotating block 206 drives the threaded shaft 208 to insert inward through the threaded sleeve 203, thus inserting the threaded shaft 208 into the ring at the rope connection end, further locking the rope connection end. The mounting plate 205 and the insertion rod 204 prevent the threaded shaft 208 from rotating on its own, avoiding friction between the rope and the threaded shaft 208 during traction and retrieval. Rotation of the threaded shaft 208 causes unlocking. The two threaded shafts 208 are locked by the insertion of the circular protrusion between them. After locking the rope connection end, the connecting block 303 and the limiting block 304 are rotated to the vertical position. When the connecting block 303 is rotated, the abutment block 302 drives the locking block 301 to insert into the rectangular through groove on the outer surface of the locking block 306. During insertion, the two limiting plates 305 need to be pressed into the locking block 306. After the locking block 301 is inserted, the limiting plate 305 is released. Under the reset action of the compression spring 307, the limiting plate 305 locks the locking block 301. Thus, by restricting the movement of the locking block 301, the abutment block 302 and the rotating block 206 are locked. Then, the soft abutment block 302 on the outer surface of the abutment block 302 abuts against the outer surface of the rope, thereby preventing the rope connection end from shaking and improving stability. Finally, the rope and the retrieval device body 1 are connected, which facilitates the traction and retrieval of the drill rod.
