Description

Technical Field

[0001] The invention belongs to the technical field of mining rock drilling equipment, and in particular relates to a drill rod magazine and engineering machinery. Background Art

[0002] Blasting holes in open-pit mines primarily rely on rock drilling equipment such as top hammer drills, down-the-hole drills, and rotary drills. Integrated open-pit drilling rigs equipped with automated engineering machinery have become a mainstream product for open-pit mine construction. These automated machinery enables rapid and stable rod storage, delivery, and loading and unloading, effectively improving drilling efficiency and reducing labor costs.

[0003] The diameter of blasting holes used in open-pit mines ranges from 80 to 440 mm, a wide range of diameters. Often, a construction area requires a wide range of blasting holes. Existing rod loading and unloading systems and rod storage devices can only use one type of drill rod, resulting in a very small range of drillable hole diameters.

[0004] At the same time, due to the uneven arrangement of drill rods in the rod bin, gravity exerts a moment on the rod bin, which causes the rod bin to spin slowly during long periods of downtime, eventually causing rods to fall off, posing a risk of safety and property loss. Summary of the Invention

[0005] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a drill rod magazine and engineering machinery that can adapt to various types of drill rods and greatly increase the range of drillable hole diameters.

[0006] In order to achieve the above objectives / solve the above technical problems, the present invention is implemented by adopting the following technical solutions: In a first aspect, the present invention provides a drill rod magazine, comprising: Main support beam; An upper pole bin and a lower pole bin are connected to the main support beam; a rod bin connecting rod, rotatably connected between the upper rod bin and the lower rod bin, capable of transporting and storing drill rods; At least one of the upper rod bin and the lower rod bin is provided with a spiral swing cylinder for driving the rod bin connecting rod to rotate; The rod bin connecting rod includes a connecting rod and two discs detachably connected to the connecting rod; The faceplate can be clamped and fixed with a plurality of drill rods of corresponding diameters.

[0007] The technical effect produced by the above setting is: the spiral swing cylinder drives the rod magazine connecting rod to rotate, and then delivers and stores the rod. By replacing the disc detachably connected to the connecting rod, it can adapt to different types of drill rods and greatly increase the aperture range of the drill hole.

[0008] Furthermore, the faceplate is annular, with a hole groove at its center adapted to the outer edge of the connecting rod, and multiple flanges are evenly arranged around its edge; the multiple flanges cooperate to form multiple drill rod grooves that match the outer edge of the drill rod; The faceplate is provided with a mounting groove connecting the hole groove to the edge of the faceplate, and the mounting groove is used to connect the faceplate to the connecting rod.

[0009] The technical effect produced by the above setting is: the faceplate is adapted to the drill rod through the drill rod groove, and the sand table can be directly replaced through the installation groove without removing the connecting rod, thereby adapting to different types of drill rods.

[0010] Furthermore, a flange connection hole is provided on the faceplate; the faceplate is fixedly connected to the connecting rod via a flange connected in the flange connection hole.

[0011] The technical effect produced by the above arrangement is that the faceplate can be better fixed firmly through the flange connection to prevent the danger caused by loosening of the drill rod.

[0012] Furthermore, the connecting rod includes an upper connecting rod and a lower connecting rod that are fixedly connected; The upper connecting rod and the lower connecting rod are both connected with a flower disc.

[0013] The above arrangement has the following technical effects: the upper connecting rod and the lower connecting rod connected by the flange are convenient to connect and firmly fixed. They are also easy to disassemble, transport, repair and replace.

[0014] Furthermore, the connecting rod is sleeved with a lower base plate at the lower end; The bottom of the lower base plate is provided with a plurality of evenly reversing inductive studs; the number of the inductive studs is the number of drill rods that can be installed in the faceplate plus one, and the position of one of the inductive studs corresponds to the bottom of the mounting groove of the faceplate, and the position of the other inductive studs corresponds to the bottom of the central axis of a drill rod installed in the faceplate; The lower rod bin includes a lower rod bin bracket and a lower rod bin casing connected to the main support beam through the lower rod bin bracket; the lower rod bin casing is cylindrical with an open top, including a bottom plate and side walls; the side walls are provided with a notch for accommodating the storage and access of drill rods; A proximity switch is provided on the bottom plate of the lower rod bin casing; When the proximity switch is close to the induction stud, a control signal is generated to control the spiral swing cylinder to stop, so that the corresponding drill rod stops at the gap of the lower rod bin.

[0015] The technical effect produced by the above setting is: through the cooperation of the proximity switch and the induction stud, the spiral swing cylinder can be stopped, thereby stopping the rotation of the rod magazine connecting rod and stopping the drill rod position at the notch, thereby storing and delivering the rod.

[0016] Furthermore, the proximity switch can be movably arranged on the bottom plate of the lower rod bin casing.

[0017] The technical effect of the above settings is: due to the different drill rod models and the time difference in the execution of control instructions, the "braking distance" of different models of drill rods may be different, which may result in the corresponding drill rod not necessarily stopping at the gap. By adjusting the position of the proximity switch, different models of drill rods can be made to stop exactly at the gap.

[0018] Furthermore, the bottom plate of the lower rod bin casing is provided with oblong holes equidistant around the center of the bottom plate, and the outer diameter of the proximity switch is smaller than the inner diameter of the oblong holes; The proximity switch is slidably arranged in the oblong hole through a blocking piece connected to the upper portion.

[0019] The technical effect of the above setting is that the above structure can easily adjust the position of the proximity switch. According to the "braking distance" of the drill rod obtained in the first test, the position of the proximity switch is adjusted, and the test is repeated until the drill rod can stop at the corresponding position.

[0020] Furthermore, the faceplate is provided with 6 drill rod slots to limit the position of the drill rod; The lower base plate is provided with 7 threaded holes for installing 7 induction bolts.

[0021] Furthermore, the proximity switch includes a rod storage proximity switch and a rod delivery proximity switch; The drill rod proximity switch is arranged at the notch and is used to generate a control signal to control the spiral swing cylinder to stop when the induction stud approaches, so that the drill rod corresponding to the position of the induction stud stops at the notch; The rod feeding proximity switch is set at the previous drill rod position at the notch, and is used to generate a control signal to control the spiral swing cylinder to stop when the sensing stud approaches, so that the next drill rod corresponding to the sensing stud position stops at the notch.

[0022] The technical effect produced by the above setting is: setting the storage rod proximity switch and the delivery rod proximity switch separately is conducive to being suitable for different working conditions respectively, and the two proximity switches are set separately to prevent the proximity switches from interfering with each other.

[0023] Furthermore, the upper rod bin includes an upper rod bin bracket and an upper rod bin casing connected to the main support beam through the upper rod bin bracket; the upper rod bin casing is cylindrical with an open bottom, including a top plate and side walls; the side walls are provided with a notch for accommodating the storage and access of drill rods, and the position of the notch of the upper rod bin casing corresponds to the position of the notch of the lower rod bin casing.

[0024] Furthermore, the upper rod bin and the lower rod bin are both provided with a mounting seat connected to the casing and a plate connected to the mounting seat; the plate is annular and fits at the opening of the casing, and its inner wall can be tangent to the outer diameter of the drill rod installed in the faceplate; the plate cooperates with the faceplate to limit the rod bin connecting rod.

[0025] The technical effect produced by the above setting is that the sticking plate and the faceplate cooperate to limit the rod bin connecting rod, and different drill rod models can be adapted by replacing the sticking plate and the faceplate.

[0026] Furthermore, an upper transmission shaft and a lower transmission shaft, both coaxial with the connecting rod, are respectively provided at both ends of the connecting rod; The upper transmission shaft is used to be rotatably connected to the upper rod bin, and the lower transmission shaft is used to be rotatably connected to the lower rod bin.

[0027] The technical effect produced by the above arrangement is that the upper transmission shaft and the lower transmission shaft facilitate the rotational connection between the connecting rod and the upper rod bin and the lower rod bin.

[0028] Furthermore, the lower rod bin bracket is rotatably connected to the lower transmission shaft via a bearing; The upper rod bin bracket is rotatably connected to the upper transmission shaft via a bearing; The spiral swing cylinder is provided on the upper rod bin bracket for driving and connecting the upper transmission shaft.

[0029] The technical effect produced by the above arrangement is that the bearing can reduce friction and also facilitate the spiral swing cylinder to exert its rotation effect.

[0030] Furthermore, a locking cylinder and a locking connecting rod are provided on the lower rod compartment; The upper rod bin casing is provided with a hinge point for connecting with the lock link, and the lock link is connected to the upper rod bin casing through a hinge and can rotate freely around the hinge point; The two hinge points of the locking oil cylinder are respectively connected to the upper rod bin casing and the locking connecting rod, which can drive the locking connecting rod to rotate and thus lock the rod bin connecting rod.

[0031] The above arrangement produces the following technical effects: the locking cylinder and locking link can lock the rod magazine connecting rod, thereby fixing the drill rod and preventing it from rotating. During use, when the rod needs to be delivered or stored, the locking cylinder drives the locking link to automatically open and release the rod magazine connecting rod. At other times, the locking link locks the rod magazine connecting rod, preventing it from rotating.

[0032] Furthermore, the lower rod bin casing is provided with a mounting hole, and the mounting hole is used to install the locking cylinder and the locking connecting rod; One end of the locking cylinder is hinged to the lower rod housing casing, and the other end is hinged to the locking connecting rod; The locking link is L-shaped and includes a first rod and a second rod that are fixedly connected. The connection between the first rod and the second rod is hinged to the lower rod bin casing; the end of the first rod is hinged to the locking cylinder; and the end of the second rod is provided with a locking hook.

[0033] Furthermore, the drill rod magazine also includes a controller, which is connected to the proximity switch and the spiral swing cylinder respectively, and is used to control the spiral swing cylinder to stop when a proximity switch signal is obtained.

[0034] Furthermore, the controller is also connected to a locking cylinder for controlling the locking cylinder to lock the rod bin connecting rod.

[0035] Furthermore, the main support beam is an aluminum alloy beam.

[0036] On the other hand, the present invention further provides an engineering machine provided with the drill rod magazine described in the first aspect.

[0037] Compared with the prior art, the present invention has the following beneficial effects: 1.

The rod bin connecting rod connects the upper and lower drill rod bins in series, and the spiral swing cylinder drives the rod bin connecting rod to rotate.

[0038] 2. By sensing the studs and the rod storage proximity switch, the rod retrieval proximity switch generates a control signal to accurately store and retrieve rods at each position in the drill rod magazine. The locking cylinder controls the locking rod to achieve the active locking function of the drill rod magazine.

[0039] 3. The detachable faceplate and rod bin plate are matched with the series of rod bin plates and faceplates provided to realize the storage and retrieval of drill rods of different diameters.

[0042] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0043] In the description of this embodiment, it should be noted that when terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", and "outside" appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings. It is only for the convenience of describing this embodiment and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on this embodiment. Example 1

[0044] like Figure 1 As shown, this embodiment provides a drill rod magazine, which mainly includes: Main support beam 5, upper pole bin 1 and lower pole bin 3 and pole bin connecting rod 2; The main support beam 5 is used to provide overall support; The rod bin connecting rod 2 is rotatably connected between the upper rod bin and the lower rod bin, and can transport and store drill rods; At least one of the upper rod bin 1 and the lower rod bin 3 is provided with a spiral swing cylinder 1-1 for driving the rod bin connecting rod 2 to rotate; The rod bin connecting rod 2 includes a connecting rod and a faceplate detachably connected to the connecting rod; The faceplate can be engaged and fixed with a plurality of drill rods of corresponding diameters. Preferably, there are two faceplates, one above and one below, which are arranged on the connecting rod to connect different drill rods.

[0045] Implementation principle: The drill rod magazine provided by the present invention mainly includes an upper rod magazine 1, a rod magazine connecting rod 2, a lower rod magazine 3, a drill rod 4, and a main support beam 5. The rod magazine connecting rod 2 is connected in series with the upper and lower drill rod magazines. The spiral swing cylinder 1-1 drives the rod magazine connecting rod to rotate, thereby delivering and storing rods. By replacing the disc detachably connected to the connecting rod, different types of drill rods can be adapted, and the aperture range of the drill hole is greatly increased. Example 2

[0046] like Figure 1 As shown, this embodiment provides a drill rod magazine, which mainly includes an upper rod magazine 1, a rod magazine connecting rod 2, a lower rod magazine 3, a drill rod 4, and a main support beam 5 (preferably an aluminum alloy beam).

[0047] like Figure 2As shown, the rod bin connecting rod 2 mainly includes an upper transmission shaft 2-1, an upper cover plate 2-2, an upper disc 2-3, an upper connecting rod 2-4, a lower connecting rod 2-5, a lower disc 2-6, a lower base plate 2-7, an induction stud, and a lower transmission shaft 2-9.

[0048] The connecting rod is divided into an upper connecting rod 2-4 and a lower connecting rod 2-5 which are fixedly connected by flanges; both the upper connecting rod 2-4 and the lower connecting rod 2-5 are connected with a faceplate.

[0049] The upper transmission shaft 2-1, the upper cover plate 2-2, and the upper connecting rod 2-4 are fixed in sequence by fasteners. The upper transmission shaft 2-1 is connected to the upper rod bin bracket 1-2 through a bearing and is connected to the spiral swing cylinder 1-1, so that the rod bin connecting rod can achieve 360° rotation.

[0050] The upper connecting rod 2-4 is provided with a flange for mounting a faceplate, and a drill rod groove 5-2 is provided on the faceplate for limiting the position of the drill rod 4.

[0051] The upper connecting rod 2-4 and the lower connecting rod 2-5 are fixed by a flange.

[0052] The lower connecting rod 2-5 is provided with a flange for mounting a faceplate, and a drill rod groove 5-2 is provided on the faceplate for cooperating with the faceplate to limit the position of the drill rod 4.

[0053] The lower connecting rod 2-5 is provided with a mounting seat for mounting the lower base plate 2-7 and the lower transmission shaft 2-9. The lower base plate 2-7 is provided with a threaded hole for mounting the induction bolt. The lower transmission shaft 2-9 is connected to the lower rod bin bracket 3-7 through a bearing.

[0054] The connecting rod is sleeved with a lower base plate 2-7 at the lower end; The bottom of the lower base plate 2-7 is provided with a plurality of evenly reversing inductive studs 2-8; the number of inductive studs 2-8 is the number of drill rods 4 that can be installed in the faceplate plus one, and the position of one inductive stud 2-8 corresponds to the bottom of the mounting groove 5-3 of the faceplate, and the position of the other inductive studs 2-8 corresponds to the bottom of the central axis of a drill rod 4 installed in the faceplate; The lower rod bin 3 includes a lower rod bin bracket 3-7 and a lower rod bin casing 3-4 connected to the main support beam 5 through the lower rod bin bracket 3-7; the lower rod bin casing 3-4 is cylindrical with an open top, including a bottom plate and side walls; a notch is provided on the side wall to accommodate the drilling rod 4; A proximity switch is provided on the bottom plate of the lower rod bin casing 3-4; When the proximity switch approaches the sensing stud 2 - 8 , a control signal is generated to control the spiral swing cylinder 1 - 1 to stop, so that the corresponding drill rod 4 stops at the gap of the lower rod bin 3 .

[0055] By cooperating with the proximity switch and the induction stud 2-8, the spiral swing cylinder 1-1 can be stopped, thereby stopping the rod bin connecting rod from rotating and stopping the drill rod 4 at the notch, thereby storing and delivering the rod.

[0056] like Figure 11 As shown, the faceplate is annular, with a hole groove 5-4 at its center adapted to the outer edge of the connecting rod, and multiple flanges 5-1 are evenly arranged around its edge; multiple flanges 5-1 cooperate to form multiple drill rod grooves 5-2 that match the outer edge of the drill rod 4; The faceplate is provided with a connecting hole slot 5-4 to the mounting slot 5-3 at the edge of the faceplate, which is used to connect the faceplate to the connecting rod. The faceplate is adapted to the drill rod 4 through the drill rod slot 5-2. The mounting slot 5-3 allows the sand table to be directly replaced without removing the connecting rod, thereby adapting to different models of drill rod 4.

[0057] The faceplate is provided with a flange connection hole 5-5, and the faceplate is fixedly connected to the connecting rod via a flange connected in the flange connection hole 5-5. By connecting via the flange, the faceplate can be better fixed firmly to prevent the danger caused by the loosening of the drill rod 4.

[0058] like Figure 3 As shown, the lower rod bin 3 mainly includes a lower rod bin plate 3-1, a lower locking cylinder 3-2, a lower locking connecting rod 3-3, a lower rod bin casing 3-4, a rod delivery proximity switch 3-5, a rod storage proximity switch 3-6, a lower rod bin bracket 3-7, etc.

[0059] like Figure 7 As shown, a lower mounting seat 3-4-2 is provided on the lower rod bin casing 3-4 for installing the lower rod bin plate 3-1, and a rotating hinge point (lower mounting hole 3-4-1) is provided on the lower rod bin casing 3-4 for installing the lower locking cylinder 3-2 and the lower locking connecting rod 3-3, so that they can rotate freely around the hinge point.

[0060] A mounting seat is provided on the lower rod bin bracket 3-7 for mounting the lower rod bin casing 3-4. The rod delivery proximity switch 3-5 and the rod storage proximity switch 3-6 are mounted in the oblong holes on the lower rod bin bracket 3-7, and their positions can be freely adjusted.

[0061] The lower rod bin bracket 3-7 is rotatably connected to the lower transmission shaft 2-9 through a bearing; The upper rod bin bracket 1-2 is rotatably connected to the upper transmission shaft 2-1 through a bearing; A spiral swing cylinder 1-1 is provided on the upper rod bin bracket 1-2 for driving and connecting the upper transmission shaft 2-1.

[0062] The bearing can reduce friction and also facilitate the spiral swing cylinder 1-1 to exert its rotation effect.

[0063] The proximity switch is movably mounted on the bottom plate of the lower rod housing casing 3-4. Specifically, the bottom plate of the lower rod housing casing 3-4 is provided with oblong holes equidistantly spaced around the center of the bottom plate. The outer diameter of the proximity switch is smaller than the inner diameter of the oblong holes. The proximity switch is slidably mounted in the oblong holes via a retaining plate connected to the upper portion. The adjustable range is approximately 10 degrees around the center of the bottom plate.

[0064] Preferably, the proximity switch includes a storage rod proximity switch 3-6 and a delivery rod proximity switch 3-5; The drill rod proximity switch 3-6 is set at the notch and is used to generate a control signal for the drill rod 4 corresponding to the position of the induction stud 2-8 to stop at the notch when the induction stud 2-8 approaches; The rod delivery proximity switch 3-5 is set at the position of the previous drill rod 4 at the notch, and is used to generate a control signal for the next drill rod 4 corresponding to the position of the induction stud 2-8 to stop at the notch when the induction stud 2-8 approaches.

[0065] The storage rod proximity switch 3-6 and the delivery rod proximity switch 3-5 are respectively provided, which is beneficial for being applicable to different working conditions. The two proximity switches are separately provided to prevent the proximity switches from interfering with each other.

[0066] During the rod feeding operation, the nth sensing stud 2-8 directly below the nth drill rod 4 approaches the rod feeding proximity switch 3-5, generating a signal for controlling the nth drill rod 4 to accurately stop at the notch Q. Where n∈{1,2,3,4,5,6}.

[0067] During the rod storage operation, the sensing stud 2-8 directly below the nth drill rod 4 approaches the rod storage proximity switch 3-6, generating a signal to control the corresponding slot of the n+1th drill rod 4 to stop accurately at position Q. Where n∈{1,2,3,4,5,6}.

[0068] To put it simply, it means to align the club in a misaligned position when sending the club forward and to align the club in a correct position when storing the club.

[0069] The above structure allows for convenient adjustment of the proximity switch position. Based on the initial test results of the drill rod 4's "braking distance," the proximity switch position can be adjusted, and repeated testing can be performed until the drill rod 4 can precisely stop at the desired location. Due to differences in drill rod 4 models and time lags in control command execution, the "braking distances" of different drill rods 4 models may vary, potentially preventing the corresponding drill rod 4 from stopping at the gap. By adjusting the proximity switch position, drill rods of all sizes can be brought to a precise stop at the gap.

[0070] Preferably, six drill rod slots 5-2 are provided on the faceplate to limit the position of the drill rod 4; and seven threaded holes are provided on the lower base plate 2-7 to install seven induction bolts.

[0071] like Figure 4As shown, the upper rod bin 1 mainly includes a spiral swing cylinder 1-1, an upper rod bin bracket 1-2, an upper rod bin casing 1-3, an upper locking cylinder 1-4, an upper locking connecting rod 1-5, and an upper rod bin plate 1-6.

[0072] like Figure 8 As shown, the upper rod housing casing 1-3 is cylindrical with an open bottom, comprising a top plate and side walls. The side walls are provided with a notch for accommodating the drill rod 4. The notch in the upper rod housing casing 1-3 corresponds vertically to the notch in the lower rod housing casing 3-4. An upper mounting seat 1-3-2 is provided above the upper rod housing casing, which has an upper mounting hole 1-3-1.

[0073] The spiral swing cylinder 1-1 is secured to the upper rod magazine support 1-2 via fasteners. The upper rod magazine casing 1-3 is also secured to the upper rod magazine support 1-2 via fasteners. A hinge point is provided on the upper rod magazine casing 1-3 for connection to the upper locking cylinder 1-4 and upper locking link 1-5. The upper locking link 1-5 is hinged to the upper rod magazine casing 1-3 and can rotate freely about the hinge point. The two hinge points of the upper locking cylinder 1-4 connect the upper rod magazine casing 1-3 to the upper locking link 1-5 and the lower locking link 3-3, respectively, controlling the opening and closing of the upper locking link 1-5. A mounting base is provided on the upper rod magazine casing 1-3 for mounting the upper rod magazine plate 1-6. By changing the type of the upper rod magazine plate 1-6 and the type of the faceplate, the type of drill rod 4 used in the drill magazine can be changed.

[0074] like Figure 10 and Figure 11 As shown, the faceplate is provided with a plurality of series models that can be switched according to needs, and the upper rod warehouse plate 1-6 and the lower rod warehouse plate 3-1 are provided with a plurality of series models that can be switched according to needs.

[0075] like Figure 10 As shown, the upper rod bin plate 1-6 and the lower rod bin plate 3-1 are both annular and are connected to the upper mounting seat 1-3-2 and the lower mounting seat 3-4-2 through the connecting hole 6-1, so as to fit in the opening of the casing. The inner wall of the plate can be tangent to the outer diameter of the drill rod 4 installed in the faceplate; the plate and the faceplate can cooperate to limit the rod bin connecting rod. Figure 7 and Figure 8 As can be seen in the figure, the upper mounting seat 1-3-2 and the lower mounting seat 3-4-2 are provided with an annular connecting hole 6-1, which is used to connect the mounting plate.

[0076] like Figure 5 and Figure 6 as well as Figure 12As shown, both the upper rod housing 1 and the lower rod housing 3 are provided with a rotation hinge (i.e., an upper mounting hole 1-3-1 and a lower mounting hole 3-4-1) for mounting the upper locking cylinder 1-4 and the lower locking cylinder 3-2, as well as the upper locking connecting rod 1-5 and the lower locking connecting rod 3-3, so that the upper locking connecting rod 1-5 and the lower locking connecting rod 3-3 can rotate about the hinge. The upper locking cylinder 1-4 and the lower locking cylinder 3-2 can drive the upper locking connecting rod 1-5 and the lower locking connecting rod 3-3 to rotate, thereby locking the rod housing connecting rod. The upper locking cylinder 1-4 and the lower locking cylinder 3-2, the upper locking connecting rod 1-5 and the lower locking connecting rod 3-3 can lock the rod housing connecting rod, thereby fixing the drill rod 4 and preventing it from rotating. During use, when the rod needs to be delivered and stored, the upper locking cylinder 1-4 and the lower locking cylinder 3-2 drive the upper locking link 1-5 and the lower locking link 3-3 to automatically open and release the rod bin link. At other times, the upper locking link 1-5 and the lower locking link 3-3 clamp the rod bin link, preventing it from rotating.

[0077] like Figure 7 and Figure 8 As shown, this device is equipped with an active locking function to avoid the risk of pole dropping. The upper mounting seat 1-3-2 and the lower mounting seat 3-4-2 of the upper pole housing casing 1-3 and the lower pole housing casing 3-4 are both provided with mounting holes for mounting the upper locking cylinder 1-4, the lower locking cylinder 3-2, the upper locking connecting rod 1-5, and the lower locking connecting rod 3-3. The upper locking cylinder 1-4 and the lower locking cylinder 3-2 are hinged at one end to the lower pole housing casing 3-4, and at the other end to the upper locking connecting rod 1-5 and the lower locking connecting rod 3-3.

[0078] Preferably, Figure 7 As shown in the figure, considering that the rotation direction of the rod bin connecting rod is possible both clockwise and counterclockwise, mounting holes are provided on both sides of the notch of the upper rod bin casing 1-3 and the lower rod bin casing 3-4 for installing the upper locking cylinder 1-4 and the lower locking cylinder 3-2 and the upper locking connecting rod 1-5 and the lower locking connecting rod 3-3, so as to adapt to rotation in two directions.

[0079] like Figure 9 As shown, the upper locking link 1-5 and the lower locking link 3-3 are L-shaped, consisting of a first rod and a second rod fixedly connected. The junction between the first and second rods is hinged to the lower rod magazine casing 3-4. The end of the first rod is hinged to the upper locking cylinder 1-4 and the lower locking cylinder 3-2. The end of the second rod is equipped with a locking hook 3-3-1. When a proximity switch signal is received, the controller controls the spiral swing cylinder 1-1 to stop. When the drill rod magazine needs to be locked, the upper locking cylinder 1-4 and the lower locking cylinder 3-2 are controlled to lock the rod magazine link.

[0080] Preferably, the present invention is further provided with a controller for respectively connecting the feed rod proximity switch 3-5, the storage rod proximity switch 3-6, the spiral swing cylinder 1-1, the upper locking cylinder 1-4 and the lower locking cylinder 3-2.

[0081] like Figure 5 and Figure 6 As shown, the working process of the drill rod magazine provided in this embodiment is as follows: Rod feeding operation: Spiral swing cylinder 1-1 drives the rod magazine connecting rod to rotate counterclockwise (viewed from top to bottom). Sensor stud 1 2-8-1 first approaches rod feeding proximity switch 3-5. This light illuminates, and spiral swing cylinder 1-1 responds by stopping, ultimately bringing drill rod 1 4-1 to a stop precisely at drill rod 4's entrance / exit position Q. Sequentially, sensor studs 2-8-2, 3 2-8-3, 4 2-8-4, 5 2-8-5, and 6 2-8-6 approach rod feeding proximity switch 3-5, ultimately bringing drill rods 2 4-2, 3 4-3, 4 4-4, 5 4-5, and 6 4-6 to a precise stop precisely at drill rod entrance / exit position Q. This completes the rod feeding operation. The larger the angle A of rod feeding proximity switch 3-5, the slower the rod feeding rate.

[0082] To store rods: Spiral swing cylinder 1-1 drives the rod magazine connecting rod to rotate clockwise (viewed from top to bottom). Sensor stud 7 2-8-7 first approaches the rod storage proximity switch 3-6. This light illuminates, and spiral swing cylinder 1-1 responds by stopping, ultimately bringing drill rod 6 4-6 to a precise stop at the drill rod entry / exit position Q. Sequentially, sensor stud 6 2-8-6, sensor stud 5 2-8-5, sensor stud 4 2-8-4, sensor stud 3 2-8-3, and sensor stud 2 2-8-2 approach the rod storage proximity switch 3-6. Ultimately, drill rods 5 4-5, 4-4, 3 4-3, 2 4-2, and 1 4-1 all accurately stop at the drill rod entry / exit position Q, completing the rod delivery operation. The larger the angle B of the rod storage proximity switch 3-6, the slower the rod storage rate.

[0083] Transport or shutdown status: Figure 12 As shown, the upper locking cylinder 1-4 and the lower locking cylinder 3-2 drive the upper locking connecting rod 1-5 and the lower locking connecting rod 3-3 to lock the drill pipe magazine. Example 3
