Description

Technical Field

[0001] This utility model relates to the field of drilling rig technology, and more specifically, to a dual-shaft drill rod changing device. Background Technology

[0002] Due to the height limit of the drilling rig, the drilling rig frame cannot be too high. However, due to the requirement for drilling depth, higher requirements are placed on the drill rod. Based on this situation, the current solution is to replace the drill rod and continue construction to meet the drilling needs.

[0003] Given this demand, replacing drill pipes has become one of the problems that needs to be solved. Currently, most mainstream drill pipe storage systems are storage units driven by a rotating mechanism, using robotic arms or other auxiliary equipment to store and retrieve drill pipes.

[0004] For example, the utility model patent with application number CN202121673930.5 and title: Drill Rod Magazine for Drilling Rigs provides the basic structural form of such drill rod magazines.

[0005] To reduce the difficulty and increase the efficiency of changing drill pipes, targeted improvements to the drill pipe magazine are needed.

[0006] In order to solve the above problems, people have been seeking an ideal technological solution. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings of existing technologies by providing a dual-axis drill pipe changing device that reduces the difficulty of changing drill pipes and increases efficiency.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is: a dual-axis drill rod changing device, comprising a two-stage motion base, a drill rod magazine, and a straightening frame;

[0009] The drill pipe magazine is installed on the two-stage motion base and its position is adjusted in the horizontal plane along with the two-stage motion base;

[0010] The opening and closing mechanism of the drill pipe magazine is installed on the straightening frame. The straightening frame straightens the drill pipe magazine through the opening and closing mechanism to prevent the drill pipe magazine from tipping over.

[0011] Based on the above, the drill pipe magazine includes a bottom rotating frame, a middle rotating shaft, and a top annular frame. The rotating frame has several positions for fixing the drill pipe head, and the annular frame has several positions for securing the top of the drill pipe. The rotating shaft is installed between the rotating frame and the annular frame and rotates with the rotating frame. One side of the annular frame has an opening and closing port, and the opening and closing mechanism is used to close the opening and closing port.

[0012] Based on the above, the annular frame includes a ring hoop and a rotating frame disposed within the ring hoop. The rotating frame rotates with the rotation shaft, and the opening and closing door is disposed on one side of the ring hoop.

[0013] Based on the above, the opening and closing mechanism includes a telescopic rod and a connecting rod installed on the uprighting frame, the opening and closing door is hinged to the ring hoop, and the telescopic rod drives the opening and closing door to perform opening and closing actions through the connecting rod.

[0014] Based on the above, the telescopic rod is a hydraulic rod, a pneumatic cylinder, or an electric actuator.

[0015] Based on the above, the two-stage motion base includes a lateral movement mechanism and a longitudinal movement mechanism. The longitudinal movement mechanism is installed on the ground, and the lateral movement mechanism is installed based on the motion slider of the longitudinal movement mechanism.

[0016] Based on the above, a drill rod head fixing mechanism is provided at each work station on the rotary frame. The drill rod head fixing mechanism includes a locking hole with a cavity and a locking pin for locking the drill rod head. The opening of the locking hole faces upward for inserting the drill rod head, and the locking pin is inserted into the locking hole from the horizontal side of the locking hole to lock the drill rod head.

[0017] Based on the above, the locking hole is integrally mounted on a slide rail radially arranged on the rotary frame, and the locking hole is hinged to the rotary shaft via a connecting rod.

[0018] Based on the above, the rotary motor used to drive the rotary frame to rotate is mounted on the transverse mechanism.

[0019] Based on the above, the locking pin is a side-pressing locking pin or a through-hole locking pin.

[0020] This utility model has substantial features and advancements compared to existing technologies. Specifically, this utility model features a vertically oriented drill rod magazine, which is stabilized by a straightening frame. The drill rod magazine is horizontally adjusted by a two-stage motion base. When a drill rod needs to be replaced, the drill rod magazine is moved to the bottom of the pile frame via the two-stage motion base. The drill rod replacement process is achieved using the lifting mechanism of the drill rod equipment, eliminating the need for intermediate equipment such as robotic arms required for transferring drill rods and providing convenience for drill rod replacement.

[0026] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0027] like Figures 1-4 As shown, a dual-axis drill pipe changing device includes a two-stage motion base 1, a drill pipe magazine 2, and a straightening frame 3.

[0028] The drill pipe magazine 2 is installed on the two-stage motion base 1 and its position is adjusted in the horizontal plane along with the two-stage motion base 1.

[0029] In this embodiment, the two-stage motion base 1 includes a transverse movement mechanism 11 and a longitudinal movement mechanism 12. The longitudinal movement mechanism 12 is installed on the ground, and the transverse movement mechanism 11 is installed based on the movement slider of the longitudinal movement mechanism 12. The longitudinal movement mechanism 12 is responsible for horizontal longitudinal position adjustment, and the transverse movement mechanism 11 is responsible for horizontal lateral position adjustment. The purpose of the two working together is to transfer the drill rod magazine 2 as a whole to the bottom of the drill frame to match the position of the drill rod power head and facilitate the replacement of drill rods.

[0030] The opening and closing mechanism 4 of the drill pipe magazine 2 is installed on the straightening frame 3. The straightening frame 3 straightens the drill pipe magazine 2 through the opening and closing mechanism 4 to prevent the drill pipe magazine 2 from tipping over.

[0031] In this embodiment, the opening and closing mechanism 4 includes a telescopic rod 41 and a connecting rod 42 installed on the straightening frame. The opening and closing door 21 on the drill pipe magazine 2 is hinged to the ring hoop 22. The telescopic rod 41 drives the opening and closing door 21 to perform opening and closing actions through the connecting rod 42. The telescopic rod 41 is a hydraulic rod, a cylinder, or an electric actuator. In this embodiment, a hydraulic rod is used.

[0032] In this embodiment, the drill rod magazine 2 includes a bottom rotating frame 23, a middle rotating shaft 24, and a top annular frame. The rotating frame 23 is provided with several stations for fixing drill rod heads. Specifically, a drill rod head fixing mechanism is provided at each station on the rotating frame 23. The drill rod head fixing mechanism includes a locking hole 25 with a cavity and a locking pin 26 for locking the drill rod head. The opening of the locking hole 25 faces upward for inserting the drill rod head. The locking pin 26 is inserted into the locking hole from the horizontal side of the locking hole to lock the drill rod head. The locking pin is a side-pressing locking pin or a through-hole locking pin. When a through-hole locking pin is used, a corresponding pin hole needs to be configured on the drill rod head.

[0033] In this embodiment, to ensure flexibility, the locking hole 25 is mounted on the slide rail 27 radially arranged on the rotary frame. The locking hole 25 is hinged to the rotary shaft through the connecting rod 28. The rotary motor used to drive the rotary frame to rotate is mounted on the transverse mechanism. The accompanying drawings are simplified, omitting the motor and only retaining the transmission pulley and belt.

[0034] The annular frame has several stations for securing the top of the drill pipe. The rotary shaft 24 is installed between the rotary frame 23 and the annular frame and rotates with the rotary frame. One side of the annular frame is provided with an opening and closing port, namely an opening and closing door 21. The opening and closing mechanism is used to close the opening and closing door 21. Specifically, the annular frame includes a ring hoop 22 and a rotating frame 29 disposed within the ring hoop. The rotating frame 29 rotates with the rotary shaft 24. The opening and closing door 21 is disposed on one side of the ring hoop 22.

[0035] Working principle explanation:

[0036] When it is necessary to replace the drill rod 5, control the two-stage motion base 1 to move the drill rod magazine 2 as a whole to be close to the bottom of the pile frame. Rotate the drill rod to be replaced to the opening and closing door 21 through the rotation operation of the rotary frame 23. At least the drill rod to be replaced on the side of the opening and closing door 21 is located directly below the pile frame.

[0037] If it is not necessary to remove the drill rod, first connect the drill rod joint, then start the lifting device of the drill rig power head. By lowering the power head, insert the upper joint of the drill rod into the corresponding joint of the power head. Control the response control mechanism of the joint to make the joint of the drill rod fully inserted and locked. Then insert the drill rod connecting pin into the drill rod joint and lock it to complete the installation process. Then lift the drill rod out of the drill rod magazine.

[0038] If it is necessary to remove the drill rod before installing a new drill rod, the slewing frame 23 needs to be rotated so that the empty work position is directly below the pile frame. First, control the drilling equipment to put the drill rod into the drill rod magazine, especially locking the bottom drill rod head first. Then, put the top of the drill rod into the corresponding work position. After closing the opening and closing door, remove the drill rod by following the reverse operation steps of the installation process. Then, install the new drill rod through the aforementioned process to complete the replacement of the drill rod.

[0039] The device is equipped with a two-stage motion platform for the drill pipe magazine, as well as a matching drill pipe magazine, making the drill pipe replacement process relatively simple and efficient.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
