DETAILED DESCRIPTION

[0025] During geological exploration, drilling equipment inserts the drill pipe into the ground to a set depth. The hollow tube inside the drill pipe can collect rock samples broken during the drilling process to form a core. After drilling is completed, the drill pipe needs to be moved to the disassembly position. The drill pipe is loaded with cores, which makes the drill pipe very heavy. Currently, the drill pipe is moved manually, which is very laborious and has low transportation efficiency.

[0026] The embodiment of the present application provides a drill rod conveying device to solve the above-mentioned technical problems. The technical scheme in the embodiment of the present application will be clearly and completely described below in conjunction with the drawings in the embodiment of the present application. Obviously, the described embodiment is a part of the embodiment of the present application, not all of the embodiments.

For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0028] like Figures 1 to 6 As shown, the drill rod conveying device provided in the embodiment of the present application includes a frame 100 , a sliding bracket 200 , an actuating mechanism 300 and a conveying mechanism 400 .

[0029] The sliding bracket 200 is slidably connected to the frame 100 along the transfer direction 1100. The actuating mechanism 300 is connected to the sliding bracket 200 and is configured to drive the sliding bracket 200 to slide on the frame 100. The transmission assembly is installed on the sliding bracket 200 and is configured to drive the drill rod 1000 placed on the transmission mechanism 400 to move along the transfer direction 1100.

[0030] When the drill rod conveying device is used to transfer the drill rod 1000, the frame 100 is fixed to the ground, and the drill rod 1000 is placed on the conveying mechanism 400 from the ground using a crane, a forklift, etc. The conveying mechanism 400 drives the drill rod 1000 to move along the transfer direction 1100, and the actuating mechanism 300 drives the sliding bracket 200 to slide along the transfer direction 1100 on the frame 100, so that the drill rod 1000 is transferred from the drilling position to the disassembly position, which is convenient for the staff to use the drill rod 1000 disassembly device to disassemble the drill rod 1000 and remove the core, and then reassemble the drill rod 1000. In addition, the drill rod conveying device can transfer the drill rod 1000 that has been reassembled after removing the core from the disassembly position to the drilling position for the drilling equipment to use again. Therefore, using the drill rod conveying device to transfer the drill rod 1000 can save manpower, and the efficiency of transferring the drill rod 1000 is high.

[0031] In the embodiments of the present application, Figure 1 and Figure 2The specific structure of realizing the sliding bracket 200 to be slidably connected to the frame 100 along the transfer direction 1100 is shown. The sliding bracket 200 is provided with a slide groove 210 extending along the transfer direction 1100; the drill rod conveying device also includes a plurality of pulleys 700, which are arranged at intervals along the transfer direction 1100 and can be rotatably connected to the frame 100 around their own axes, and the plurality of pulleys 700 are located in the slide groove 210.

[0032] The plurality of pulleys 700 are used to carry the sliding bracket 200 by supporting the inner wall of the slide groove 210. Furthermore, when the sliding bracket 200 moves along the transfer direction 1100 on the frame 100, the plurality of pulleys 700 rotate around their own axes in the slide groove 210, so that rolling friction occurs between the sliding bracket 200 and the frame 100, thereby making the movement process of the sliding bracket 200 smoother and less worn.

[0033] Of course, in other embodiments of the present application, the sliding bracket 200 and the frame 100 are slidably connected through other structures; for example, the drill rod conveying device also includes a slide rail and a slider, the slide rail is installed on the frame 100 along the transfer direction 1100, the slider is installed on the slide rail, and the sliding bracket 200 is connected to the slider.

[0034] like Figure 5 As shown, in the embodiment of the present application, the actuating mechanism 300 includes a mounting bracket 310, a first actuating member 320, a driving sprocket 330 and an actuating chain 340. The first actuating member 320 is connected to the mounting bracket 310, and the output shaft of the first actuating member 320 is installed with the driving sprocket 330. The actuating chain 340 is partially wound around the driving sprocket 330, and the actuating chain 340 is partially fixedly connected to the sliding bracket 200.

[0035] When the actuating mechanism 300 drives the sliding bracket 200 to move, the output shaft of the first actuating member 320 drives the driving sprocket 330 to rotate, and the actuating chain 340 partially wrapped around the driving sprocket 330 moves with the rotation of the driving sprocket 330, and then the actuating chain 340 drives the sliding bracket 200, so that the sliding bracket 200 slides on the frame 100 along the transfer direction 1100.

[0036] In the above structure, the driving sprocket 330 and the actuating chain 340 transmit the power output by the first actuating member 320 to the sliding bracket 200; compared with other transmission structures, the actuating chain 340 has a higher load-bearing capacity, so that when a drill rod 1000 containing a core is placed on the sliding bracket 200, the first actuating member 320 outputs a larger power and drives the sliding bracket 200 through the driving sprocket 330 and the actuating chain 340; and, the driving sprocket 330 and the actuating chain 340 can work in a relatively harsh environment, thereby enabling the actuating mechanism 300 to adapt to geological exploration scenarios.

[0037] Exemplarily, the first actuator 320 includes a first hydraulic motor 321 and a reducer 322, the reducer 322 is installed on the mounting bracket 310, the first hydraulic motor 321 is connected to the reducer 322, and the input shaft of the reducer 322 is connected to the output shaft of the first hydraulic motor 321, and the output shaft of the reducer 322 is installed with a driving sprocket 330; the first hydraulic motor 321 can provide a large torque, thereby enabling the sliding bracket 200 to slide along the transfer direction 1100 while carrying a heavier drill rod 1000 containing a core.

[0038] Of course, in other examples of the embodiments of the present application, the first actuator 320 can also be a servo motor, and the driving sprocket 330 is installed on the output shaft of the servo motor. When the servo motor is powered on, it drives the sliding bracket 200 to move through the driving sprocket 330 and the actuating chain 340.

[0039] Continue to refer to Figure 5 The actuating mechanism 300 also includes two driven sprockets 350; the two driven sprockets 350 are rotatably connected to the mounting bracket 310 around their own axes, the axes of the two driven sprockets 350 are parallel to the axis of the driving sprocket 330, and are located between the first actuating member 320 and the sliding bracket 200; wherein, the two parts of the actuating chain 340 extending from the driving sprocket 330 are partially wound around the two driven sprockets 350, so that the parts of the actuating chain 340 extending from the two driven sprockets 350 are parallel to the transfer direction 1100.

[0040] The portion of the actuating chain 340 extending from the two driven sprockets 350 is parallel to the transfer direction 1100, so that the force applied by the actuating chain 340 to the sliding bracket 200 is parallel to the transfer direction 1100, thereby avoiding the sliding bracket 200 from being subjected to a downward force component, thereby reducing the friction and wear of the sliding bracket 200; the moving distance of the actuating chain 340 is equal to the moving distance of the sliding bracket 200, thereby improving the transmission efficiency of the actuating chain 340.

[0041] Of course, the actuating mechanism 300 is not Figure 5 The above description is limited. In other embodiments of the present application, the actuating mechanism 300 may also be in other structural forms. For example, the actuating mechanism 300 includes a linear module, which is arranged along the transfer direction 1100 and fixedly connected to the frame 100 , and the slider of the linear module is connected to the sliding bracket 200 .

[0042] like Figure 2 and Figure 3As shown, the transmission mechanism 400 includes a second actuator 410, a transmission assembly 420, and a plurality of transmission chain assemblies 430. The plurality of transmission chain assemblies 430 are installed on the sliding bracket 200 at intervals along the transfer direction 1100, and are configured to carry and drive the drill rod 1000 to move along the transfer direction 1100. The transmission assembly 420 is connected to the plurality of transmission chain assemblies 430. The second actuator 410 is installed on the sliding bracket 200, and the output end of the second actuator 410 is connected to the transmission assembly 420, and is configured to drive the plurality of transmission chain assemblies 430 through the transmission assembly 420.

[0043] When the conveying mechanism 400 carries and drives the drill rod 1000 to move along the transfer direction 1100, the second actuator 410 transmits power to multiple conveying chain assemblies 430 through the transmission assembly 420. Each conveying chain assembly 430 is capable of carrying the drill rod 1000 and applying friction force in the transfer direction 1100 to the drill rod 1000, so that the drill rod 1000 moves on the conveying chain assembly 430.

[0044] Exemplarily, the second actuator 410 may be a second hydraulic motor, the output end of the second hydraulic motor is connected to the plurality of conveyor chain assemblies 430 through the transmission assembly 420, and the output end of the second hydraulic motor drives the plurality of conveyor chain assemblies 430 to work when rotating, so as to drive the drill rod 1000 to move along the transfer direction 1100; Figure 3 The transmission mechanism 400 shown in FIG. 4 includes three transmission chain assemblies 430 . The second actuator 410 transmits power to the three transmission chain assemblies 430 through the transmission assembly 420 . The drill rod 1000 is driven by the three transmission chain assemblies 430 in sequence.

[0045] Compared with other conveying structures, the conveyor chain assembly 430 can carry heavier loads and can transport empty drill rods 1000 and drill rods 1000 containing cores; the conveyor chain assembly 430 is easy to maintain and can work in harsh environments and can be adapted to geological exploration scenarios.

[0046] Specifically, Figure 4 Each conveyor chain assembly 430 includes two rotating shafts 431, a first sprocket 432, a second sprocket 433 and a conveyor chain 434. The two rotating shafts 431 are arranged in parallel along the transfer direction 1100, both ends of the rotating shafts 431 are rotatably connected to the sliding bracket 200, and at least one rotating shaft 431 is connected to the transmission assembly 420. The first sprocket 432 and the second sprocket 433 are respectively installed on the two rotating shafts 431. The conveyor chain 434 is wound around the first sprocket 432 and the second sprocket 433.

[0047] When the conveying chain assembly 430 is working, the conveying chain 434 is used to place the drill rod 1000, and the transmission assembly 420 drives at least one rotating shaft 431 to rotate. For example, the transmission assembly 420 can drive the rotating shaft 431 equipped with the first sprocket 432 to rotate, and then the first sprocket 432 rotates and drives the conveying chain 434, and the conveying chain 434 drives the second sprocket 433 meshing with the conveying chain 434 to rotate. During the rotation process, the conveying chain 434 drives the carried drill rod 1000 to move along the transfer direction 1100.

[0048] Furthermore, the conveying chain assembly 430 also includes a chain guide 435, which is connected to the sliding bracket 200 along the transfer direction 1100 and is located below the conveying chain 434 to carry the conveying chain 434 and enable the conveying chain 434 to move along a predetermined trajectory. At the same time, the chain guide 435 can reduce the friction between the conveying chain 434 and the sliding bracket 200, thereby extending the service life of the conveying chain 434.

[0049] Continue to refer to Figure 3 In the embodiment of the present application, the transmission assembly 420 includes a first transmission assembly 421 connecting two adjacent conveying chain assemblies 430 , and a second transmission assembly 422 connecting one of the conveying chain assemblies 430 and the second actuator 410 .

[0050] The power of the second actuator 410 is transmitted to one of the conveyor chain assemblies 430 through the second transmission assembly 422, and then transmitted to the other conveyor chain assemblies 430 through the first transmission assembly 421. The first transmission assembly 421 enables multiple conveyor chain assemblies 430 to work synchronously. When the two ends of the drill rod 1000 are respectively located at two adjacent conveyor chain assemblies 430, the two adjacent conveyor chain assemblies 430 can synchronously drive the drill rod 1000 to move along the transfer direction 1100, thereby avoiding relative movement between the conveyor chain assembly 430 and the drill rod 1000 and wearing the outer surface of the drill rod 1000.

[0051] For example, Figure 3 The middle conveying mechanism 400 includes three conveying chain assemblies 430, the second transmission assembly 422 connects the conveying chain assembly 430 located in the middle and the second actuator 410, the conveying chain assemblies 430 located on both sides are connected to the conveying chain assembly 430 located in the middle through the first transmission assembly 421, the power of the second actuator 410 is transmitted to the conveying chain assembly 430 located in the middle through the second transmission assembly 422, so that the conveying chain assembly 430 located in the middle starts to work, and the conveying chain assembly 430 located in the middle transmits the power to the two conveying chain assemblies 430 located on both sides through the two first transmission assemblies 421 respectively, so that the two conveying chain assemblies 430 located on both sides start to work.

[0052] Specifically, refer to Figure 3In the embodiment of the present application, the first transmission component 421 includes a first transmission chain and two first transmission sprockets, the two first transmission sprockets are respectively installed on the output end of the second actuator 410 and one of the transmission chain components 430, and the first transmission chain is wound around the two first transmission sprockets; the second transmission component 422 includes a second transmission chain and two second transmission sprockets, the two second transmission sprockets are respectively installed on two adjacent transmission chain components 430, and the second transmission chain is wound around the two second transmission sprockets.

[0053] It should be noted that the conveying mechanism 400 is not limited to the above-mentioned specific structure. In other embodiments of the present application, the conveying mechanism 400 may also be in other structural forms. For example, the conveying mechanism 400 includes a plurality of flat belt conveyors, which are sequentially arranged along the transfer direction 1100 and fixedly connected to the sliding bracket 200; the flat belt conveyors can carry the drill rod 1000 and drive the drill rod 1000 to move along the transfer direction 1100.

[0054] like Figure 2 As shown, in the embodiment of the present application, the drill rod conveying device further includes at least one limiting mechanism 500, and the limiting mechanism 500 includes two blocking assemblies 510. The two blocking assemblies 510 are located on both sides of the conveying mechanism 400 and connected to the sliding bracket 200, and a moving channel extending along the transfer direction 1100 and accommodating the drill rod 1000 is formed between the two blocking assemblies 510.

[0055] When the conveying mechanism 400 drives the drill rod 1000 to move along the transfer direction 1100 , the drill rod 1000 passes through the moving channel, and the two blocking assemblies 510 can block both sides of the drill rod 1000 to prevent the drill rod 1000 from falling off the sliding bracket 200 .

[0056] For example, refer to Figure 2 The drill rod conveying device includes two limiting mechanisms 500, which are spaced apart along the transfer direction 1100, and the spacing between the two limiting mechanisms 500 is less than the length of the drill rod 1000. Of course, in other examples, the drill rod conveying device may also include only one limiting mechanism 500, or include three, four, or other numbers of limiting mechanisms 500.

[0057] Specifically, continue to refer to Figure 2 The blocking assembly 510 includes a first limiting frame 511 and a smooth strip 512; the first limiting frame 511 is connected to the sliding bracket 200, and the smooth strip 512 is connected to the side of the first limiting frame 511 facing the drill rod 1000 to be close to the drill rod 1000.

[0058] When the drill rod 1000 moves in the moving channel, the smooth bars 512 of the two blocking assemblies 510 clamp the drill rod 1000, and the drill rod 1000 is in close contact with the rollers of the smooth bars 512. When the drill rod 1000 moves, the rollers on the smooth bars 512 rotate, so that there is rolling friction between the drill rod 1000 and the blocking assemblies 510. The blocking assemblies 510 prevent the drill rod 1000 from falling from the sliding bracket 200 and keep it moving along the transfer direction 1100, while reducing the wear between the blocking assemblies 510 and the drill rod 1000.

[0059] Furthermore, if Figure 2 As shown, the limiting mechanism 500 also includes a second limiting frame 520 and a first telescopic rod 530; the second limiting frame 520 is rotatably connected to one of the first limiting frames 511; the two ends of the first telescopic rod 530 are respectively rotatably connected to the second limiting frame 520 and the corresponding first limiting frame 511, and are configured to drive the second limiting frame 520 to rotate to the top of the moving channel.

[0060] Specifically, the second limiting frame 520 is connected to one of the first limiting frames 511 through a hinge, and both ends of the first telescopic rod 530 are respectively hinged to the first limiting frame 511 and the second limiting frame 520. Exemplarily, the first telescopic rod 530 may be a hydraulic cylinder.

[0061] When the drill rod 1000 is placed in the moving channel, the first telescopic rod 530 is extended, and the first telescopic rod 530 drives the second limiting frame 520 to rotate to the top of the moving channel, thereby blocking the drill rod 1000 from moving upward.

[0062] Of course, the limiting mechanism 500 is not limited to the above structure. In other embodiments of the present application, the limiting mechanism 500 can also be in other structural forms. For example, the limiting mechanism 500 also includes two baffles, which are respectively located on both sides of the conveying mechanism 400 and connected to the sliding bracket 200.

[0063] like Figure 2 As shown, in an embodiment of the present application, the drill rod conveying device also includes a plurality of lifting mechanisms 600, which are arranged at intervals along the transfer direction 1100, are all connected to the sliding bracket 200, and are configured to support the drill rod 1000 and lift in the height direction.

[0064] Before placing the drill rod 1000 on the conveying mechanism 400, the plurality of lifting mechanisms 600 are raised, and the drill rod 1000 is placed on the lifting mechanisms 600, and then the lifting mechanisms 600 gradually lower the drill rod 1000 with the lifting mechanisms 600 until the surface of the drill rod 1000 is located on the conveying mechanism 400, at which time the conveying mechanism 400 starts to work, so as to avoid the wear of the drill rod 1000 caused by the drill rod 1000 being directly placed on the conveying mechanism 400. When the conveying mechanism 400 conveys the drill rod 1000 to the end of the conveying mechanism 400, the plurality of lifting mechanisms 600 are raised and lift the drill rod 1000, so that the drill rod 1000 is separated from the conveying mechanism 400, so as to avoid the wear of the drill rod 1000 when the conveying mechanism 400 continues to work.

[0065] For example, Figure 2 It is shown that the drill rod conveying device includes four lifting mechanisms 600, and the conveying mechanism 400 includes three conveying chain assemblies 430. The four lifting mechanisms 600 are arranged at intervals along the transfer direction 1100, and a conveying chain assembly 430 is arranged between each adjacent lifting mechanism 600.

[0066] Specifically, Figure 6 As shown, the lifting mechanism 600 includes a fixed plate 610, a lifting platform 620 and a second telescopic rod 630; the fixed plate 610 is connected to the sliding bracket 200; the lifting platform 620 is located above the fixed plate 610; the second telescopic rod 630 is installed on the fixed plate 610, and the top end of the second telescopic rod 630 is connected to the lifting platform 620, and is configured to drive the lifting platform 620 to move in the height direction.

[0067] When the lifting mechanism 600 needs to be raised, the second telescopic rod 630 is extended, and the front end of the second telescopic rod 630 drives the lifting platform 620 to move upward; when the lifting mechanism 600 needs to be lowered, the second telescopic rod 630 is shortened, and the front end of the second telescopic rod 630 drives the lifting platform 620 to move downward.

[0068] Exemplarily, the second telescopic rod 630 may be a hydraulic cylinder.

[0069] Further, continue to refer to Figure 6 The lifting mechanism 600 also includes a guide cylinder 640 and a guide rod 650; the guide cylinder 640 is connected to the fixed plate 610; the guide rod 650 is arranged parallel to the telescopic rod, the top end of the guide rod 650 is connected to the lifting platform 620, and passes through the fixed plate 610, and is slidably connected to the guide cylinder 640.

[0070] When the lifting platform 620 moves in the height direction, the guide cylinder 640 and the guide rod 650 can guide the moving direction of the lifting platform 620, ensuring that the lifting platform 620 moves smoothly and accurately in the height direction.

[0071] Of course, the lifting mechanism 600 is not limited to the above structure. In other embodiments of the present application, the lifting mechanism 600 can also be in other structural forms. For example, the lifting mechanism 600 includes a plurality of electric lifting platforms, which are arranged along the transfer direction 1100 and fixedly connected to the sliding bracket 200.

[0072] like Figure 1 and Figure 2 As shown, the drill rod conveying device also includes a blocking bracket 900, which is connected to one end of the sliding bracket 200. The blocking bracket 900 can block the drill rod 1000 moving in the transfer direction 1100 to prevent the drill rod 1000 from falling from the sliding bracket 200.

[0073] like Figure 1 As shown, the drill rod conveying device further includes a pull-wire displacement sensor 800, the pull-wire displacement sensor 800 is fixedly connected to the frame 100, and the pull wire of the pull-wire displacement sensor 800 is fixedly connected to the sliding bracket 200, and the pull wire of the pull-wire displacement sensor 800 is extended along the transfer direction 1100. When the sliding bracket 200 moves on the frame 100, the pull-wire displacement sensor 800 can measure the moving distance of the sliding bracket 200.
