Description

Technical Field

[0001] The utility model relates to the technical field of drill rod magazines, and more specifically to a turntable type drill rod magazine. Background Art

[0002] In order to facilitate the safe and efficient drilling of relatively deep medium-deep holes, the drilling rig is equipped with a drill rod magazine, which includes a turntable drill rod magazine and a clip-type drill rod magazine. Among them, the turntable drill rod magazine has a simple structure and simple operation, and is widely used in drilling rigs.

[0003] A turntable drill rod magazine consists of a drill rod indexing plate and a rocker mechanism. The drill rod indexing plate has drill rod positions for receiving drill rods, and the rocker mechanism is used to insert and remove drill rods from the drill rod indexing plate. The positions corresponding to where the rocker mechanism inserts and removes drill rods are called rod receiving positions. In related art, the drill rod indexing plate also has empty positions to prevent drill rods from being installed in these empty positions, thereby preventing interference with the rocker mechanism on the drill rod indexing plate.

[0004] However, in the related art, when rotating the drill rod indexing plate to pick up and place the drill rod, the human eye is mainly relied on to identify the position of the empty space to determine whether to stop the rotation of the drill rod indexing plate. The operation is difficult, and personnel are prone to misoperation after working for a long time, which increases the chance of damaging the equipment.

[0005] Therefore, how to automatically identify the position of the empty space of the drill rod indexing plate to automatically control the drill rod indexing plate to stop rotating is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

DETAILED DESCRIPTION

[0040] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] The core of the utility model is to provide a turntable type drill rod library, which can automatically identify the position of the empty position of the drill rod indexing disk and automatically control the drill rod indexing disk to stop rotating.

[0042] Please refer to Figures 1 to 6 , the embodiment of the present invention provides a turntable drill rod library, including a mounting base 1, a drill rod indexing plate 2, at least two sensing members 3, a first sensing switch 4 and a second sensing switch 5, the drill rod indexing plate 2 can rotate relative to the mounting base 1, the drill rod indexing plate 2 is provided with at least two drill rod positions 21 and an empty position 22, the drill rod position 21 is used to clamp the drill rod 10, and the empty position 22 is vacant to avoid installing the drill rod 10, the drill rod indexing plate 2 has at least two rotating positions, the sensing member 3 and the drill rod position 21 have a one-to-one correspondence, and the position between the sensing member 3 and the drill rod indexing plate 2 is relatively fixed; the first sensing switch 4 and the second sensing switch 5 are both provided on the mounting base 1, when the drill rod indexing plate 2 is in the rotating position and the first sensing switch 4 senses the sensing member 3, the drill rod indexing plate 2 can rotate in the first direction 30, when the drill rod indexing plate 2 is in the rotating position and the first sensing switch 4 does not sense the sensing member 3 (such as Figure 4 As shown), the drill rod indexing plate 2 cannot rotate in the first direction 30; when the drill rod indexing plate 2 is in the rotating position and the second induction switch 5 senses the induction member 3, the drill rod indexing plate 2 can rotate in the second direction 40 opposite to the first direction 30. When the drill rod indexing plate 2 is in the rotating position and the second induction switch 5 does not sense the induction member 3 (as shown), the drill rod indexing plate 2 cannot rotate in the first direction 30; when ... Figure 6As shown), the drill rod indexing plate 2 cannot rotate toward the second direction 40.

[0043] It should be noted that the drill rod indexing plate 2 can stop at each rotation station intermittently in sequence, so that each drill rod position 21 can be aligned with the connecting rod position 20 (such as Figure 3 and Figure 5 As shown), the connecting rod position 20 refers to the position where the drill rod 10 is placed in the drill rod position 21 or the drill rod 10 is removed from the drill rod position 21, that is, for each drill rod position 21, the position where the drill rod 10 is put into and taken out of the warehouse is the same. In addition, the sensing member 3 and the drill rod position 21 have a one-to-one correspondence, that is, there are several sensing members 3 for several drill rod positions 21, and the sensing member 3 and the drill rod position 21 have a corresponding relationship in position, which can be a one-to-one alignment relationship, or the sensing member 3 and the drill rod 10 have a certain relative position relationship. In this way, when the drill rod indexing plate 2 is in a certain rotation position and the first sensing switch 4 or the second sensing switch 5 detects the sensing member 3, it indicates that the current position of interest is the drill rod position 21. In this case, the drill rod indexing plate 2 can continue to rotate (when the first sensing switch 4 When the sensing element 3 is detected, the drill rod indexing plate 2 is rotated in the first direction 30. When the second sensing switch 5 detects the sensing element 3, the drill rod indexing plate 2 is rotated in the second direction 40) so that the drill rod position 21 currently concerned is rotated to the rod connecting position 20. When the drill rod indexing plate 2 is in a certain rotation position and the first sensing switch 4 or the second sensing switch 5 cannot detect the sensing element 3, it indicates that the current position of concern is not the drill rod position 21, but the empty position 22. At this time, the drill rod indexing plate 2 is no longer rotated, that is, the empty position 22 is prevented from rotating to the rod connecting position 20.

[0044] It can be understood that one of the first direction 30 and the second direction 40 is the rotation direction of the drill rod 10 into the warehouse, and the other is the rotation direction of the drill rod 10 out of the warehouse. The drilling rod 10 into the warehouse refers to placing the drill rod 10 into the drill rod position 21, and the drill rod 10 out of the warehouse refers to removing the drill rod 10 from the drill rod position 21. That is, when the drill rod dividing plate 2 rotates toward the rotation direction of the drill rod 10 into the warehouse, multiple drill rods 10 can be placed in each drill rod position 21 in turn, and when the drill rod dividing plate 2 rotates toward the rotation direction of the drill rod 10 out of the warehouse, the drill rods 10 in each drill rod position 21 can be taken out in turn.

[0045] When the first direction 30 is the rotation direction for the drill rods 10 to enter the warehouse, the second direction 40 is the rotation direction for the drill rods 10 to leave the warehouse. In this case, when the drill rod indexing plate 2 rotates along the first direction 30, when the drill rod indexing plate 2 is in the rotation position and the first induction switch 4 cannot detect the induction member 3, it indicates that all the drill rod positions 21 have been put into the drill rods 10 (such as Figure 3When the drill rod indexing plate 2 rotates along the second direction 40, when the drill rod indexing plate 2 is in the rotating position and the second induction switch 5 cannot detect the induction member 3, it indicates that the drill rods 10 in all the drill rod positions 21 have been taken out (as shown). Figure 5 When the first direction 30 is the rotation direction of the drill rod 10 when it is unloaded, the second direction 40 is the rotation direction of the drill rod 10 when it is loaded into the warehouse.

[0046] It can be seen from this that the turntable drill rod storage provided by the embodiment of the present invention can automatically identify the positions of the drill rod position 21 and the empty position 22 on the drill rod dividing plate 2 by utilizing the cooperation of the first sensing switch 4, the second sensing switch 5 and at least two sensing parts 3, thereby automatically controlling the continued rotation or stopping of the drill rod dividing plate 2 along the first direction 30 and the second direction 40, thereby realizing precise control of the forward and reverse rotation of the drill rod dividing plate 2, avoiding the use of the human eye to identify the empty position 22 to stop the rotation of the drill rod dividing plate 2, thereby reducing the difficulty of operation, preventing misoperation caused by human factors, reducing the probability of equipment damage, and reducing maintenance costs.

[0047] In addition, as the use time increases, the rotation error of the drill rod indexing plate 2 accumulates, which can easily cause the rotation position of the drill rod indexing plate 2 to deviate, causing a position deviation between the sensing member 3 and the first sensing switch 4 or the second sensing switch 5, which can easily cause inaccurate sensing. In order to solve this technical problem, in some embodiments, the first sensing switch 4 and the second sensing switch 5 can be respectively arranged on the mounting base 1 with adjustable positions. In other words, the setting position of the first sensing switch 4 and the second sensing switch 5 on the mounting base 1 is adjustable. In this way, when a position deviation occurs between the sensing member 3 and the first sensing switch 4 or the second sensing switch 5, the position of the first sensing switch 4 or the second sensing switch 5 can be adjusted so that the sensing member 3 can be accurately aligned with the first sensing switch 4 or the second sensing switch 5, thereby ensuring detection accuracy.

[0048] It should be noted that this embodiment does not limit the specific implementation method of the adjustable positions of the first induction switch 4 and the second induction switch 5 , as long as the positions of the first induction switch 4 and the second induction switch 5 are adjustable.

[0049] In some embodiments, the mounting base 1 is provided with a first arc-shaped hole 121 and a second arc-shaped hole 122 of preset lengths. The first sensor switch 4 can be adjusted along the length of the first arc-shaped hole 121, and the second sensor switch 5 can be adjusted along the length of the second arc-shaped hole 122. In other words, this embodiment utilizes the first arc-shaped hole 121 and the second arc-shaped hole 122 to limit the position adjustment paths of the first sensor switch 4 and the second sensor switch 5, respectively. When the position of the first sensor switch 4 needs to be adjusted, the first sensor switch 4 is moved along the extension direction of the first arc-shaped hole 121. When the position is in place, the first sensor switch 4 is fixed to the mounting base 1. When the position of the second sensor switch 5 needs to be adjusted, the second sensor switch 5 is moved along the extension direction of the second arc-shaped hole 122. When the position is in place, the second sensor switch 5 is fixed to the mounting base 1. This facilitates quick position adjustment of the first sensor switch 4 and the second sensor switch 5, and facilitates quick positioning of the first sensor switch 4 and the second sensor switch 5.

[0050] In addition, the embodiment of the present invention does not limit the fixing methods of the first induction switch 4 and the second induction switch 5 to the mounting base 1. For example, the first induction switch 4 and the second induction switch 5 can be connected to the mounting base 1 respectively by means of snap connection or fastener connection, as long as the positions of the first induction switch 4 and the second induction switch 5 are convenient to adjust and the first induction switch 4 and the second induction switch 5 are convenient to fix after being adjusted into place.

[0051] In addition, the embodiment of the present invention does not limit the specific installation position of the sensor 3, as long as the position between the sensor 3 and the drill rod indexing plate 2 is relatively fixed and can rotate synchronously with the rotation of the drill rod indexing plate 2.

[0052] To facilitate the placement of the sensing element 3, in some embodiments, the rotary drill rod magazine further includes a drill rod support plate 6. The drill rod support plate 6 is fixed relative to the drill rod indexing plate 2, and the sensing element 3 is disposed on the drill rod support plate 6. In other words, in this embodiment, the drill rod support plate 6 is utilized to position the sensing element 3, thereby locating the sensing element 3 in a suitable position and facilitating the coordinated sensing of the sensing element 3 with the first and second sensing switches 4 and 5. The drill rod support plate 6 is fixed relative to the drill rod indexing plate 2, meaning that the drill rod support plate 6 and the drill rod indexing plate 2 can rotate synchronously, thereby ensuring that the sensing element 3 rotates synchronously with the drill rod indexing plate 2.

[0053] Furthermore, to facilitate rotational movement of the drill rod indexing plate 2 in the first direction 30 and the second direction 40, in some embodiments, the mounting base 1 is provided with a rotatable center rod 7 and a rotation drive mechanism 8. The drill rod indexing plate 2 and the rotation drive mechanism 8 are respectively connected to the center rod 7; the rotation drive mechanism 8 is used to drive the center rod 7 to rotate. In other words, in this embodiment, the rotation drive mechanism 8 drives the center rod 7 to rotate, causing the center rod 7 to drive the rotation of the drill rod indexing plate 2. The drill rod indexing plate 2 can be connected to any position of the center rod 7, which facilitates positioning the drill rod indexing plate 2 in a suitable position and facilitates reliable positioning of the drill rod 10.

[0054] It is understandable that the rotary drive mechanism 8 can be any drive mechanism that can output bidirectional rotation. For example, the rotary drive mechanism 8 can be a rotary cylinder. In addition, the present embodiment does not limit the specific connection method between the drill rod indexing plate 2 and the center rod 7, as long as the connection between the two can be achieved. In some embodiments, the outer periphery of the center rod 7 is provided with a fixing portion, the drill rod indexing plate 2 is sleeved on the outer periphery of the center rod 7 and fits with the fixing portion. At the same time, the drill rod indexing plate 2 and the fixing portion are fixed by fasteners, thereby achieving a fixed connection between the drill rod indexing plate 2 and the center rod 7.

[0055] Furthermore, considering the stability of the structure, in some embodiments, the mounting base 1 includes a first mounting base 11 and a second mounting base 12, the center rod 7 is connected between the first mounting base 11 and the second mounting base 12, and the first mounting base 11 and the second mounting base 12 are respectively provided with a rotatable drill rod support plate 6, and the drill rod support plate 6 is provided with a clamping position for clamping the two ends of the drill rod 10. In other words, in this embodiment, the first mounting base 11 and the second mounting base 12 are used to rotationally support the two ends of the center rod 7, which is conducive to improving the stability of the rotation of the center rod 7, and thus improving the stability of the drill rod indexing plate 2. In addition, the clamping positions of the drill rod support plates 6 rotatably provided on the first mounting base 11 and the second mounting base 12 are used to support the two ends of the drill rod 10, which is conducive to improving the stability of the drill rod 10 after it is placed in the drill rod position 21 of the drill rod indexing plate 2.

[0056] In addition, in some embodiments, the carousel drill rod storage further includes a swing arm mechanism 9, which is provided with a drill rod gripper for retrieving and placing drill rods 10. The swing arm mechanism 9 can swing the drill rod gripper to a rod receiving position 20, so that the drill rod gripper can retrieve a drill rod 10 from a drill rod position 21 or place a drill rod 10 into the drill rod position 21 at the rod receiving position 20. In other words, this embodiment utilizes the swing arm mechanism 9 to both store and remove drill rods 10 at the same position (i.e., the rod receiving position 20), resulting in a simple structure and convenient control.

[0057] In addition, the above embodiment does not limit the specific shape of the drill rod position 21, as long as the drill rod position 21 can position the drill rod 10. In some embodiments, the drill rod position 21 includes a curved groove surface 211 and a flat groove surface 212. The curved groove surface 211 is used to cooperate with the outer periphery of the drill rod 10; the flat groove surface 212 is tangentially connected to one side of the curved groove surface 211, and the flat groove surface 212 and the curved groove surface 211 form an open groove. It can be understood that the flat groove surface 212 is tangentially connected to one side of the curved groove surface 211, so that the overall groove size of the drill rod position 21 is maximized at the opening, thereby providing a certain guiding effect, facilitating the placement of the drill rod 10 into the drill rod position 21. In addition, the curved groove surface 211 cooperates with the outer periphery of the drill rod 10 to effectively limit the position of the drill rod 10.

[0058] In addition, the above embodiment does not limit the specific shape of the empty space 22 , as long as the empty space 22 is in an empty state and can avoid interference with the rocker mechanism 9 of the connecting rod position 20 .

[0059] In some embodiments, the space 22 is a U-shaped groove extending radially inward from the end of the drill rod indexing plate 2. In other words, in this embodiment, the U-shaped groove is formed on the drill rod indexing plate 2 to form the space 22, which can effectively avoid air gaps. In addition, it can be understood that the U-shaped groove is easy to process and manufacture.

[0060] In addition, in order to facilitate the control of the rotation of the drill rod indexing plate 2, in some embodiments, the empty positions 22 and all the drill rod positions 21 are evenly distributed along the circumference of the drill rod indexing plate 2. In this way, the structure of the drill rod indexing plate 2 is simple and easy to manufacture.

[0061] It should also be noted that, in this specification, relational terms such as first and second, etc. are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0062] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0063] The above describes in detail the carousel drill rod magazine provided by the present invention. This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above examples is only intended to help understand the method and core concept of the present invention. It should be noted that for those skilled in the art, various improvements and modifications can be made to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the present invention.
