[0031] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0032] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0034] In the description of the present invention, it should be noted that if the terms "upper", "lower", "inside", "outside", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings, or is the orientation or position relationship in which the product of the invention is usually placed when used. It is only for the convenience of describing the present invention 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 cannot be understood as a limitation on the present invention.

[0035] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0036] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0037] As mentioned in the background technology, it is difficult to fasten anchor rods or drill rods in existing rod storage bins, which makes the anchor rods or drill rods easily move or slide axially, affecting the grasping accuracy; and the versatility is poor, and it is difficult to adapt to anchor rods or drill rods of different rod diameters.

[0038] In order to improve the above-mentioned problem, the present application provides a rod clamping mechanism 10 for a rod storage bin 010, which can automatically lock or unlock anchor rods or drill rods of different sizes, greatly improving its adaptability when applied to different working conditions.

[0039] See also Figure 1 The present application provides a rod clamping mechanism 10 for a rod storage bin 010 , which includes a chuck device 100 and a driving device 300 ; wherein the chuck device 100 includes a locking plate 110 and a limiting plate 130 .

[0040] In detail, the driving device 300 is drivingly connected to the locking plate 110 to drive the locking plate 110 to move radially along the chuck device 100 so that the locking plate 110 approaches or moves away from the limiting plate 130 to lock or unlock the rod.

[0041] In other words, the locking plate 110 and the limiting plate 130 clamp the rod together, so that the rod is accurately positioned, and the movement of the rod due to inaccurate positioning is reduced. In addition, based on the position adjustment of the locking plate 110 by the driving device 300, the clamping spacing can be adjusted accordingly, so as to adapt to rods with different rod diameters.

[0042] In addition, it should be noted that the rods here specifically refer to drill rods or anchor rods. Based on different actual application scenarios, the rods clamped by the clamping mechanism 10 are also different. The staff can adjust the rods stored in the clamping mechanism 10 according to actual conditions, which is not limited in this application.

[0043] In some embodiments, the chuck device 100 includes a plurality of locking plates 110. To ensure the positional relationship between the plurality of locking plates 110 and the limiting plate 130, as shown in FIG. Figure 2 As shown, the chuck device 100 includes a guide plate 150 , and all locking plates 110 slide with the guide plate 150 ; the limiting plate 130 is provided with a through hole 131 coaxially arranged with the guide plate 150 , and the guide plate 150 is located in the through hole 131 .

[0044] It should be noted that when the locking plate 110 slides to the farthest distance from the limit plate 130, the edge of the guide plate 150 can be jointly supported on the rod together with the wall of the through hole 131, and the size of the rod at this time is the maximum rod diameter that can be locked; when the locking plate 110 slides to the closest distance to the limit plate 130, the locking plate 110 and the limit plate 130 are jointly supported on the rod, and the size of the rod at this time is the minimum rod diameter that can be locked.

[0045] On the basis of the above, taking into account that there may be motion interference problems between the multiple locking plates 110 when they move, the guide plate 150 is provided with a plurality of linear slide grooves 151 in a circular array. The linear slide grooves 151 correspond one-to-one to the locking plates 110 and extend along the radial direction of the guide plate 150.

[0046] It can be understood that the one-to-one correspondence here refers to both the one-to-one correspondence between the positions of the locking plates 110 and the linear slide grooves 151 , and the one-to-one correspondence between the numbers of the locking plates 110 and the linear slide grooves 151 .

[0047] As an optional embodiment, the chuck device 100 also includes an active amplitude variable disk 170 coaxially arranged with the guide disk 150; accordingly, the active amplitude variable disk 170 is provided with a plurality of arc-shaped slide grooves 171 in a circumferential array, the arc-shaped slide grooves 171 correspond one-to-one to the locking plate 110, and extend radially along the active amplitude variable disk 170.

[0048] On the basis of the above, the active luffing disc 170 is connected to the driving device 300 and is used to drive all the locking plates 110 to move synchronously under the action of the driving device 300. Specifically, when the driving device 300 drives the active luffing disc 170 to rotate, the active luffing disc 170 will drive the multiple locking plates 110 to rotate synchronously. During the rotation process, due to the limitation of the linear slide slot 151 provided by the guide disc 150, the locking plates 110 move radially at the same time to lock or unlock the rod.

[0049] In some embodiments, in order to ensure the stability of the locking plate 110 and reduce the displacement deviation during the motion transmission process, the locking plate 110 is located between the active amplitude variable plate 170 and the guide plate 150 .

[0050] On this basis, in order to realize that the locking plate 110 is slidably connected with the active amplitude variable plate 170 and the guide plate 150 at the same time, as shown in FIG. Figure 3 and Figure 4 As shown, the locking plate 110 includes a supporting plate 111 , a first limiting column 113 and a second limiting column 115 , and the first limiting column 113 and the second limiting column 115 are respectively disposed on two opposite sides of the supporting plate 111 .

[0051] Among them, the first limit column 113 slides with the linear slide groove 151 to ensure radial movement along the guide plate 150 under the constraint of the linear slide groove 151; the second limit column 115 slides with the arcuate slide groove 171 to ensure rotation along with the active amplitude variable plate 170 under the constraint of the arcuate slide groove 171.

[0052] Furthermore, there are two first limiting posts 113, which are spaced apart on the abutting plate 111 and simultaneously cooperate with the linear slide groove 151. According to the principle that two points determine a straight line, the two first limiting posts 113 spaced apart can repeatedly define the linear slide groove 151 in the radial direction, thereby ensuring that the locking plate 110 moves accurately in the radial direction, approaches or moves away from the limiting plate 130, thereby locking or unlocking the rod.

[0053] In addition, it should be noted that in other embodiments, the locking plate 110, the active amplitude variable plate 170 and the guide plate 150 can be arranged in this order, and the locking plate 110 can be sequentially penetrated by an arcuate slide groove 171 and a linear slide groove 151 through a limiting column, which will not be repeated in this application.

[0054] In some embodiments, the abutting plate 111 includes a first plate portion 1111, a second plate portion 1113, and a third plate portion 1115 connected in sequence at an angle. The first limiting column 113 and the second limiting column 115 are respectively disposed on opposite sides of the second plate portion 1113, and the first plate portion 1111 and the third plate portion 1115 are disposed opposite to each other and form a gripping structure together with the second plate portion 1113 to provide a stable gripping effect.

[0055] Optionally, the length dimension of the third plate portion 1115 is greater than the length dimension of the first plate portion 1111. Based on this, the end of the first plate portion 1111 can also cooperate with the third plate portion 1115 and the wall of the through hole 131 to resist a rod with a larger rod diameter. On the basis of the above, in order to further adapt to rods with a larger rod diameter range, the first plate portion 1111 and the third plate portion 1115 can be arranged at an angle.

[0056] It should also be emphasized that in order to prevent the rod from being stuck in the above-set abutment plate 111, the first plate portion 1111, the second plate portion 1113 and the third plate portion 1115 are sequentially connected in a circular arc transition. Accordingly, the end of the first plate can also be set to an arc shape, so as to ensure that the rod is smoothly unlocked and disengaged in actual application scenarios.

[0057] In other embodiments, a V-shaped notch may be directly provided on the supporting plate 111 to accommodate rods of different shapes or sizes, which will not be described in detail in the present application.

[0058] In some embodiments, such as Figure 5 As shown, the clamping rod mechanism 10 further includes a shaft 500, and the guide plate 150, the active amplitude change plate 170 and the limit plate 130 are all coaxially arranged with the shaft 500. In addition, the driving device 300 includes a connecting plate 310 and a driving cylinder 330, one end of the connecting plate 310 is connected to the shaft 500, and the other end is connected to the driving cylinder 330, that is, the driving cylinder 330 is eccentrically connected to the shaft 500, forming a crank cylinder that can convert linear motion into curved motion.

[0059] On the basis of the above, the driving cylinder 330 is drivingly connected to the active luffing disc 170, so as to drive the active luffing disc 170 to move, thereby correspondingly driving the locking plate 110 to move. In other embodiments, the driving device 300 can be directly set as a rotating driving member such as a hydraulic motor or an electric motor, which will not be described in detail in this embodiment.

[0060] Furthermore, considering the stability of motion transmission, the chuck device 100 further includes a connecting rod 190 , the opposite ends of which are respectively connected to the active amplitude change plate 170 and the driving cylinder 330 , and the axis of the connecting rod 190 is parallel to the axis of the shaft 500 .

[0061] Based on the setting of the above-mentioned rotation mechanism, the driving device 300 can more accurately control the rotation speed and direction of the active amplitude variable disc 170, thereby improving the motion transmission efficiency.

[0062] Taking this embodiment as an example, the working principle and working process of the rod clamping mechanism 10 for the rod storage bin 010 provided in this application are as follows:

[0063] When multiple rods need to be locked, the driving cylinder 330 is started to drive the active amplitude change plate 170 to rotate, and all the locking plates 110 are driven to rotate synchronously. At this time, the guide plate 150 is fixed, and based on the restriction of the linear slide groove 151 provided thereon, the locking plate 110 moves radially and linearly, and locks multiple rods together with the hole wall of the through hole 131 provided by the limiter. When multiple rods need to be unlocked, the driving cylinder 330 can be moved in the opposite direction.

[0064] In summary, the present application provides a rod clamping mechanism 10 for a rod storage bin 010, which includes a chuck device 100 and a drive device 300; wherein the chuck device 100 includes a locking plate 110 and a limiting plate 130. In detail, the drive device 300 is connected to the locking plate 110 for driving and driving the locking plate 110 to move radially along the chuck device 100, so that the locking plate 110 approaches or moves away from the limiting plate 130, and locks or unlocks the rod. In other words, the locking plate 110 and the limiting plate 130 jointly clamp the rod, so that the rod is accurately positioned, and the movement of the rod due to inaccurate positioning is reduced. Moreover, based on the position adjustment of the locking plate 110 by the drive device 300, the clamping spacing can be adjusted accordingly, so as to adapt to rods with different rod diameters.

[0065] In addition, the utility model further provides a rod storage bin 010, comprising a central rod 70 and a rod clamping mechanism for the rod storage bin according to any of the aforementioned embodiments, and the chuck device 100 and the drive device 300 are both connected to the central rod 70. Since the rod storage bin 010 comprises the rod clamping mechanism 10, it can also automatically lock or unlock anchor rods or drill rods of different sizes, greatly improving its adaptability when applied to different working conditions. This application will not be repeated.

[0066] It should be noted that, in some embodiments, the central rod 70 here may refer to the shaft rod 500 in the aforementioned embodiment, the guide plate 150 is fixedly connected to the shaft rod 500, the active amplitude change plate 170 is rotatably connected to the shaft rod 500, and the limit plate 130 is fixedly connected to the shaft rod 500 through the bent arm 30. In actual application scenarios, the clamping rod mechanism 10 can also be connected to other devices through the bent arm 30, such as an arm frame or a rotating beam, etc.

[0067] And, if Figure 6As shown, the central rod 70 here may also refer to a transmission rod connected to the shaft rod 500 through a swing cylinder 50. In addition, the above-mentioned clamping rod mechanism 10 may also be correspondingly provided at the other end of the transmission rod, so as to lock and unlock the two ends of the rod respectively. It should be noted that the two driving devices 300 can be driven synchronously by a remote controller; the swing cylinder 50 can drive the above-mentioned clamping rod mechanism 10 to rotate as a whole to realize the rod uncoupling action.

[0068] In addition, the utility model provides an anchor trolley, comprising a boom and a rod storage bin 010 of any one of the aforementioned embodiments, and the rod storage bin 010 is connected to the boom. Since the anchor trolley comprises the above-mentioned rod storage bin 010, it can also automatically lock or unlock anchors or drill rods of different sizes, greatly improving its adaptability when applied to different working conditions. This application will not be repeated.

[0069] In some embodiments, the anchor trolley can be a double-arm anchor drilling trolley, and the above-mentioned storage bin 010 is configured on one of the arms. In other embodiments, the anchor trolley can also be a single-arm anchor drilling trolley, and the above-mentioned storage bin 010 is configured accordingly.

[0070] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model.
