[0002] During engineering geological survey or geological exploration, a drilling rig is required for drilling operations, during which the drill rod needs to be lengthened and disassembled. During the operation, the power head or turntable of the drilling rig drives the drill rod for drilling operations; among them, as a power head drilling rig, the top drill rod is directly connected to the output shaft of the power head; as a rotary drilling rig, the top drill rod is connected to the turntable through a square drill rod.
[0003] When lengthening a drill pipe, first expose the top drill pipe joint through the drilling rig's lifting system, then separate the drilling rig's power head (with output shaft) or turntable (with square drill rod) from the top drill pipe (old drill rod) joint, move the drilling rig's power head or turntable so that it is connected to the new drill pipe, lift the new drill pipe and move it to just above the top drill pipe, and then connect the top drill pipe to the new drill pipe. Usually, the new drill pipe will be prepared near the wellhead.
[0004] During the disassembly work, the drill pipe to be disassembled will be leaked out of the well and separated. After separation, the drill pipe to be disassembled will be moved by the power head or turntable of the drilling rig and placed vertically on the drill pipe placement plate, which has a plurality of placement holes for placing the drill pipe.
[0005] During the above-mentioned lengthening and disassembly operations, due to the shaking of the power head or turntable of the drilling rig, it is difficult to align the power head or turntable of the drilling rig with the new drill rod, the new and old drill rods, and the drill rod with the placement hole.

DETAILED DESCRIPTION
[0020] The following is combined with Figure 1-5 This application is described in further detail.
[0021] The embodiment of the present application discloses a survey drilling tool disassembly and assembly device.
[0022] Reference Figure 1-Figure 3 A survey drilling tool disassembly and assembly device comprises a center rod seat 1, a rope 2 whose one end is detachably connected to the center rod seat 1, and a limiting mechanism, wherein the limiting mechanism comprises an arc plate 3 and a sealing plate 4, the arc plate 3 is fixedly connected to the other end of the rope 2, one end of the sealing plate 4 is rotatably connected to one end of the arc plate 3, and can be rotated to the other end thereof to be clamped with the other end of the arc plate 3 to form a closed limiting hole 5.
[0023] When in use, the center rod seat 1 is fixed near the wellhead, and the distance from the center rod seat 1 to the borehole and the new drill rod is equal; when aligning the drilling rig and the new drill rod, the arc plate 3 and the sealing plate 4 are used to fix the docking part of the drilling rig and the new drill rod in the limiting hole 5, and then a force is applied to the limiting mechanism, so that the docking part of the drilling rig and the new drill rod can be moved to the position of the new drill rod on the same circumference and docked; after docking, the drilling rig lifts the new drill rod, fixes the lower end of the new drill rod in the limiting hole 5 again, and applies a force to the limiting mechanism. The new drill rod can be moved in the opposite direction to accurately dock with the top drill rod; in addition, when the drill rod is placed under the drill rod hole by using the drilling rig, the drill rod can be clamped by using the limit hole 5; in each connection process, the connection of the limit mechanism is utilized, and the positioning of the center rod seat 1 and the rope 2 is utilized to keep the drill rod or the drilling rig moving on the same circle, thereby reducing shaking, improving the technical problem that the drilling rig is difficult to align with the new drill rod and the new and old drill rods during the drill rod lengthening operation, and improving the technical problem that the drill rod is difficult to align with the placement hole during the disassembly operation.
[0024] Of course, when docking the drilling rig and the new drill rod, or docking the new drill rod connected to the drilling rig and the top drill rod, the large displacement can be directly moved by the drilling rig itself, and when docking, the limit mechanism is used to limit the position. Of course, during the large displacement process, the limit mechanism can also be used to limit the position to a certain extent. Large displacement: refers to the displacement of the new drill rod moving to the top of the top drill rod, the displacement of the drilling rig moving to the top of the prefabricated new drill rod, and the displacement of the disassembled drill rod moving to the placement plate.
[0025] The arc plate 3 and the sealing plate 4 clamping the drilling rig specifically refer to clamping the power head (with an output shaft) or the rotary table (with a square drill rod) of the drilling rig.
[0026] During specific use, the placement plate for placing the disassembled drill rod can be moved. It only needs to move the placement plate so that the placement holes are located on the same circumference.
[0027] When the drilling rig hoists the new drill rod and the arc plate 3 and the sealing plate 4 clamp the new drill rod, the arc plate 3 and the sealing plate 4 can release the drilling rig during the hoisting process, but form a certain surrounding posture until the new drill rod is lifted into place and then clamps the new drill rod.
[0028] As a specific solution of this embodiment, the arc plate 3 and the sealing plate 4 are both "C" shaped, and the arc length is less than the semicircular arc length, so as to form an opening for the drill rod to enter and exit.
[0029] On the basis of the above-mentioned embodiment, both ends of the arc plate 3 and the sealing plate 4 are fixedly connected with straight plates or "L"-shaped plates to expand the opening.
[0030] Reference Figure 1 , Figure 2The center rod seat 1 comprises a vertical rod seat 11 and a fixing sleeve 12 threadedly connected to the vertical rod seat 11, so that the height of the fixing sleeve 12 can be changed by rotating the fixing sleeve 12 for use. One end of the rope 2 is detachably connected to the fixing sleeve 12.
[0031] The rope 2 may be a chain or a cable.
[0032] As a specific solution of this embodiment, the vertical rod seat 11 is arranged vertically, and a support plate is welded to the lower end, and the support plate is provided with a plurality of screw holes so as to fix it to the ground by bolts (expansion bolts).
[0033] Based on the above embodiment, a plurality of positioning holes 111 are vertically spaced apart on the vertical rod seat 11, a plurality of internal threaded holes 121 are circumferentially formed on the fixing sleeve 12, and a second limiting rod 13 whose end portion of one of the internal threaded holes 121 is threadedly connected to penetrate into one of the positioning holes 111.
[0034] The height of the fixing sleeve 12 is limited by the second limiting rod 13 being simultaneously inserted into the positioning hole 111 and the internal threaded hole 121 located on the same straight line.
[0035] As a parallel solution, at least two limit nuts can be threadedly connected to the vertical rod seat 11 , and the multiple limit nuts are respectively located on the upper side and the lower side of the fixing sleeve 12 to form a height limit for the fixing sleeve 12 .
[0036] In this embodiment, the fixing sleeve 12 opens upward to form a storage groove 122 so that the rope 2 can be placed in the storage groove 122 to form a storage function.
[0037] On the basis of the above embodiment, the side wall of the fixing sleeve 12 is provided with a rope threading hole 123 for the rope 2 to pass through, and is threadedly connected with a limit screw 14 whose end is pressed against the rope 2, so that the length of the rope 2 between the central rod seat 1 and the arc plate 3 is limited by the limit screw 14. Then, one end of the rope 2 can be coiled in the storage groove 122, and when necessary, the limit screw 14 can be loosened to adjust the length of the rope 2.
[0038] Furthermore, a lower pressing plate 124 located in the rope threading hole 123 is abutted or rotatably connected to the end of the limiting screw 14 . The lower pressing plate 124 opens downward and presses down on the rope 2 to improve the fixing effect on the rope 2 .
[0039] As a parallel solution, one end of the rope 2 can also be directly wound around the central pole seat 1.
[0040] Reference Figure 3-Figure 5 The arc plate 3 and / or the sealing plate 4 are both rotatably connected with at least two rolling elements 8. In the process of clamping the drill rod by the arc plate 3 and the sealing plate 4, the side of the rolling element 8 abuts against the drill rod to reduce friction by rotation.
[0041] As a specific solution, an arc groove 9 is vertically penetrated on the arc plate 3 and / or the sealing plate 4, a screw 91 is vertically penetrated on the arc groove 9, and the end of the screw 91 has a thread and is threadedly connected with a nut. A through hole 92 is horizontally penetrated on the arc plate 3 and / or the sealing plate 4. A rotating shaft hole is coaxially opened on the rolling element 8 for the rod of the screw 91 to pass through, and the side of the rolling element 8 is transmitted from the through hole 92 to achieve contact with the drill rod.
[0042] During clamping, the distance between two adjacent rolling elements 8 can be adjusted by loosening and adjusting the position of the screw rod 91, so as to achieve clamping and limiting of drill rods with different diameters.
[0043] Reference Figure 3-Figure 5 A rotating shaft 31 is fixed to one end of the arc plate 3 , and one end of the sealing plate 4 is rotatably connected to the rotating shaft 31 , so that the arc plate 3 and the sealing plate 4 are rotatably connected through the rotating shaft 31 .
[0044] A limiting groove 32 is provided on the outer side of the other end of the arc plate 3. A sliding hole 41 is provided through the other end of the sealing plate 4, and a first limiting rod 6 is adapted and slidably connected at the sliding hole 41. A spring 7 is sleeved on one end of the first limiting rod 6. The two ends of the spring 7 are respectively fixedly connected to the end of the first limiting rod 6 and the sealing plate 4, and the other end of the first limiting rod 6 extends into the limiting groove 32. By utilizing the elastic force of the spring 7, the other end of the first limiting rod 6 extends into the limiting groove 32, so that the sealing plate 4 and the arc plate 3 are clamped together, forming a closed limiting hole 5.
[0045] One end of the first limiting rod 6 is in a “T” shape to achieve a fixed connection with one end of the spring 7 , and to facilitate applying force to the first limiting rod 6 to make the first limiting rod 6 escape from the limiting groove 32 .
[0046] On the basis of the above embodiment, an inclined surface 61 is provided at the other end of the first limiting rod 6. When the sealing plate 4 rotates and engages with the arc plate 3, the inclined surface 61 faces the arc plate 3, so that under the guidance of the inclined surface 61, the first limiting rod 6 overcomes the elastic force of the spring 7 and slides, so that the first limiting rod 6 smoothly enters the limiting groove 32.
[0047] Furthermore, a guiding surface matching the inclined surface 61 is provided on the other end side of the arc plate 3, so that when the sealing plate 4 rotates toward the arc plate 3, the inclined surface 61 hits the guiding surface, causing the first limiting rod 6 to slide. Then, as the sealing plate 4 rotates, the first limiting rod 6 automatically enters the limiting groove 32.
[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
