Description

Technical Field

[0001] This invention relates to the field of explosives loading vehicle technology, and more particularly to a device and method for retracting and extending a delivery tube. Background Technology

[0002] As a high-risk industry, safety is paramount in mining blasting. In blasting operations such as underground mining and tunnel development, mechanical loading is required, inserting the delivery pipe of the charging vehicle into the blast hole. Currently, the maximum insertion depth of the delivery pipe in a charging vehicle is approximately 50 meters. To load deeper blast holes, it is necessary to improve the rigidity of the delivery pipe, the conveying capacity of the pipe feeder, and the length of the delivery pipe reel. Among these, increasing the active length of the delivery pipe reel is crucial. During the pipe winding process, because the delivery pipe is rigid, grooves are usually installed on the reel to secure it, allowing it to be wound onto the reel. Therefore, current underground charging vehicle pipe winding devices cannot use multi-layer winding to increase the length of the delivery pipe reel; instead, they typically increase the width or radius of the reel. Due to space constraints underground, the size design of the charging vehicle is limited, and the size of the delivery pipe reel cannot be significantly increased. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to overcome the shortcomings of the prior art and provide a tube winding and unwinding device for a drug delivery tube, which can wind the drug delivery tube in multiple layers.

[0004] The present invention also provides a method for taking in and releasing tubes.

[0005] This invention provides the following technical solution:

[0006] According to a first aspect of the present invention, a tube delivery device for a drug delivery tube includes: a roll assembly comprising a roll; at least one limiting component disposed on the roll assembly, the limiting component comprising a first limiting member; and a drug delivery tube wound around the roll, the drug delivery tube being located between the roll and the first limiting member, the drug delivery tube being capable of forming multiple winding layers on the roll, wherein in any two adjacent winding layers, the winding layer closer to the roll along the radial direction of the roll is a first winding layer, and the winding layer further away from the roll along the radial direction of the roll is a second winding layer, and the second winding layer is wound around the first winding layer, wherein when the second winding layer is wound around the first winding layer, the first limiting member is pressed against the second winding layer, and the first limiting member is pressed against the unwound portion of the first winding layer.

[0007] According to an embodiment of the present invention, the drug delivery tube take-up and take-up device further includes a second limiting member, which is disposed on the roll assembly and spaced apart from the roll. The second limiting member is rotatably connected to the first limiting member, and the first limiting member can approach the roll under the action of the second limiting member.

[0008] According to an embodiment of the present invention, the second limiting member includes an elastic reset part, one end of the elastic reset part is connected to the roll assembly, and the other end of the elastic reset part is connected to the first limiting member. When the first limiting member moves away from the roll, the first limiting member can tend to move closer to the roll under the action of the elastic reset part.

[0009] According to an embodiment of the present invention, the second limiting member further includes a first connecting portion and a second connecting portion. The two ends of the first connecting portion are connected to the reel assembly, and the first connecting portion is spaced apart from the reel assembly. One end of the second connecting portion is fixedly connected to the first connecting portion, and the other end of the second connecting portion is rotatably connected to the first limiting member. The elastic reset portion is a reset spring. The reset spring is sleeved on the first connecting portion, and one end of the reset spring abuts against the reel assembly, and the other end of the reset spring abuts against the second connecting portion. The second connecting portion can approach the reel assembly under the action of the reset spring.

[0010] According to an embodiment of the present invention, a drug delivery tube take-up and take-up device includes a plurality of limiting components, which are spaced apart on the roll assembly along the circumference of the roll. Each limiting component includes a first limiting member. In any two adjacent winding layers, when the second winding layer is wound on the first winding layer, each first limiting member is pressed against the second winding layer, and each first limiting member is pressed against the unwound portion of the first winding layer.

[0011] According to an embodiment of the present invention, the first limiting member has a flexible layer disposed in a direction close to the roll. In any two adjacent winding layers, when the second winding layer is wound around the first winding layer, the flexible layer is pressed against the second winding layer, and the flexible layer is pressed against the unwound portion of the first winding layer.

[0012] According to an embodiment of the present invention, the drug delivery tube take-up and drop device further includes a transmission assembly, the transmission assembly including a driving member, a first transmission member and a second transmission member, the driving member being chain-driven with the first transmission member, the first transmission member being fixedly connected with the second transmission member and coaxially arranged with the first transmission member and the second transmission member, and the second transmission member being chain-driven with the rotating shaft of the drum.

[0013] According to an embodiment of the present invention, the drug delivery tube take-up and release device further includes a tube arrangement assembly. The tube arrangement assembly includes a drive shaft, a fixing member, and a tube arrangement component. One end of the fixing member is fixed to the drum assembly, and the other end of the fixing member is rotatably connected to the drive shaft. The tube arrangement component is sleeved on the drive shaft and is capable of moving along the axial direction of the drum on the drive shaft. The tube arrangement component is movably connected to the take-up and release end of the drug delivery tube, and the take-up and release end of the drug delivery tube is capable of moving relative to the tube arrangement component along the circumferential direction of the drum.

[0014] According to an embodiment of the present invention, the transmission assembly further includes a third transmission member, which is fixedly connected to the drum and is coaxially arranged with the rotation shaft of the drum. The transmission shaft is chain-driven with the third transmission member.

[0015] The inlet and outlet tube retraction device of the drug delivery tube of the present invention has the following advantages:

[0016] In the aforementioned drug delivery tube take-up and unwinding device, the drug delivery tube can be wound onto a drum, and the take-up and unwinding of the drug delivery tube can be achieved by rotating the drum. Since the drug delivery tube can form multiple winding layers on the drum, the take-up and unwinding length of the aforementioned drug delivery tube take-up and unwinding device can be increased when the drug delivery tube is wound into multiple layers on the drum. Furthermore, since the drug delivery tube is located between the drum and the first limiting member, the first limiting member can limit the drug delivery tube during the take-up and unwinding process, preventing the drug delivery tube from detaching during the take-up and unwinding process. Moreover, it is not necessary to apply a pre-tightening force to the drug delivery tube to make the arrangement of the drug delivery tube tight during the take-up and unwinding process. Simultaneously, in any two adjacent winding layers, when the second winding layer is wound around the first winding layer, the first limiting member is pressed against the second winding layer and against the unwound portion of the first winding layer. Therefore, during the process of the second winding layer winding around the first winding layer, the first limiting member can press against the exposed drug delivery tube, providing pressure to the exposed drug delivery tube and preventing it from detaching during the tube winding and unwinding process. This ensures a tighter arrangement of the drug delivery tubes during the winding and unwinding process. Thus, the aforementioned drug delivery tube winding and unwinding device can perform multi-layer winding of the drug delivery tube, thereby increasing the winding and unwinding length of the drug delivery tube winding and unwinding device.

[0017] According to a second aspect of the present invention, a tube loading and unloading method is applicable to the tube loading and unloading device for the above-mentioned drug delivery tube, comprising: controlling a drive member to rotate so that the drive member drives a first transmission member to rotate; the first transmission member drives a second transmission member to rotate; the second transmission member drives a rotating shaft of a reel to rotate; and the rotating shaft of the reel drives a transmission shaft to rotate so that a tube-laying member moves circumferentially along the transmission shaft.

[0018] The tube feeding and receiving method of the present invention has the following advantages:

[0019] In the above-described tube loading and unloading method, the first transmission component can be driven to rotate by the driving component, which in turn drives the second transmission component to rotate. The second transmission component then drives the rotating shaft of the drum to rotate, allowing the drum to rotate. Simultaneously, the rotating shaft of the drum drives the transmission shaft to rotate, causing the tube-laying component to move circumferentially along the transmission shaft. This allows the tube-laying component to lay tubes while the drum rotates, thereby realizing the loading and unloading of the drug delivery tube in the above-described tube loading and unloading device. This process requires no manual operation and can automate the loading and unloading process of the drug delivery tube.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the template description is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0038] Reference Figure 1 as well as Figure 2 As shown, the tube delivery device for the delivery tube involved in the embodiment of the present invention includes: a reel assembly 100, at least one limiting assembly 200, and a delivery tube 300.

[0039] Specifically, the roll assembly 100 includes a roll 110; at least one limiting component 200 is disposed on the roll assembly 100, the limiting component 200 including a first limiting member 210; a drug delivery tube 300 is wound on the roll 110, and the drug delivery tube 300 is located between the roll 110 and the first limiting member 210, the drug delivery tube 300 can form multiple winding layers 310 on the roll 110, and in any two adjacent winding layers 310, the winding tube 300 is radially closer to the roll 110. The winding layer 310 of the drum 110 is a first winding layer 310 (not shown), and the winding layer 310 that is radially away from the drum 110 is a second winding layer 310 (not shown). The second winding layer 310 is wound on the first winding layer 310. When the second winding layer 310 is wound on the first winding layer 310, the first limiting member 210 is pressed against the second winding layer 310, and the first limiting member 210 is pressed against the unwound portion of the first winding layer 310.

[0040] Specifically, in the above embodiments, referring to Figure 2 As shown, when the drum 110 is along the first direction, i.e. Figure 2 When the drum 110 rotates in the x-direction (counterclockwise), the aforementioned tube winding and unwinding device winds up the tube 300. Figure 2 When the tube rotates in the y-direction (clockwise), the aforementioned tube delivery device releases the tube 300.

[0041] In the above embodiments, the delivery tube 300 can be wound around the drum 110 so that the delivery tube 300 can be unwound and retracted by rotating the drum 110. Since the delivery tube 300 can form multiple winding layers 310 on the drum 110, the length of the delivery tube can be increased when the delivery tube 300 is wound in multiple layers on the drum 110. Furthermore, since the delivery tube 300 is located between the drum 110 and the first limiting member 210, the first limiting member 210 can limit the delivery tube 300 during the unwound and retracted process, preventing the delivery tube 300 from detaching during the unwound and retracted process. Moreover, there is no need to apply a pre-tightening force to the delivery tube 300 to make the arrangement of the delivery tube 300 tight during the unwound and retracted process. Simultaneously, in any two adjacent winding layers 310, when the second winding layer 310 is wound around the first winding layer 310, the first limiting member 210 is pressed against the second winding layer 310, and also against the unwound portion of the first winding layer 310. Therefore, during the process of the second winding layer 310 winding around the first winding layer 310, the first limiting member 210 can press against the exposed drug delivery tube 300, providing pressure to the exposed drug delivery tube 300 and preventing it from detaching during the tube winding and unwinding process. This ensures a tighter arrangement of the drug delivery tube 300 during the winding and unwinding process. Thus, the aforementioned drug delivery tube winding and unwinding device can perform multi-layer winding of the drug delivery tube 300, thereby increasing the winding and unwinding length of the drug delivery tube winding and unwinding device.

[0042] Continue to refer to Figure 1 as well as Figure 2 As shown, the limiting component 200 also includes a second limiting member 220, which is disposed on the drum assembly 100 and spaced apart from the drum 110. The second limiting member 220 is rotatably connected to the first limiting member 210, and the first limiting member 210 can approach the drum 110 under the action of the second limiting member 220.

[0043] It is understandable that, since the second limiting member 220 is spaced apart from the drum 110, a winding space (not shown) for the delivery tube 300 can be reserved between the second limiting member 220 and the drum 110, and the first limiting member 210 connected to the second limiting member 220 can move closer to or further away from the drum 110 within the winding space. When the aforementioned delivery tube take-up and undoing device takes up the delivery tube 300, as the winding layer 310 increases, the first limiting member 210 can move away from the drum 110 under the action of the delivery tube 300. When the aforementioned delivery tube take-up and undoing device undoes the delivery tube 300, as the winding layer 310 decreases, the first limiting member 210 can move closer to the drum 110 under the action of the second limiting member 220, so as to squeeze and limit the delivery tube 300. Meanwhile, since the first limiting member 210 and the second limiting member 220 are rotatably connected, during the process of releasing the medicine delivery tube 300, the first limiting member 210 can roll relative to the medicine delivery tube 300 in the first direction to provide a thrust in the second direction to the medicine delivery tube 300 so that the medicine delivery tube 300 can be released in the second direction. During the process of retracting the medicine delivery tube 300, the first limiting member 210 can roll relative to the medicine delivery tube 300 in the second direction to provide a thrust in the first direction to the medicine delivery tube 300 so that the medicine delivery tube 300 can be retracted in the first direction. Therefore, the above-mentioned medicine delivery tube release and retraction device can release and retract the tree spirit tube without applying external pulling force.

[0044] Reference Figure 1 as well as Figure 3 As shown, the second limiting member 220 includes an elastic reset part 221. One end of the elastic reset part 221 is connected to the drum assembly 100, and the other end of the elastic reset part 221 is connected to the first limiting member 210. When the first limiting member 210 moves away from the drum 110, the first limiting member 210 can tend to move closer to the drum 110 under the action of the elastic reset part 221.

[0045] It is understandable that when the aforementioned tube take-up and undocking device is taking in the tube 300, as the winding layer 310 increases, the first limiting member 210 can move away from the drum 110 under the action of the tube 300. At this time, the first limiting member 210 can provide pressure to the elastic reset part 221, so that the elastic reset part 221 has elastic potential energy. At this time, the elastic potential energy of the elastic reset part 221 is fed back to the first limiting member 210, so that the first limiting member 210 can exert a squeezing effect on the tube 300 to achieve tight winding of the tube 300. When the aforementioned tube take-up and undocking device is undoing the tube 300, as the winding layer 310 decreases, the first limiting member 210 can move closer to the drum 110 under the action of the elastic potential energy of the elastic reset part 221 to exert a squeezing and limiting effect on the tube 300.

[0046] Continue to refer to Figure 1 as well as Figure 3 As shown, the second limiting member 220 also includes a first connecting part 222 and a second connecting part 223. The two ends of the first connecting part 222 are connected to the drum assembly 100, and the first connecting part 222 is spaced apart from the drum 110. One end of the second connecting part 223 is fixedly connected to the first connecting part 222, and the other end of the second connecting part 223 is rotatably connected to the first limiting member 210. The elastic reset part 221 is a reset spring (not shown). The reset spring is sleeved on the first connecting part 222, and one end of the reset spring abuts against the drum assembly 100, and the other end of the reset spring abuts against the second connecting part 223. The second connecting part 223 can approach the drum 110 under the action of the reset spring.

[0047] Specifically, in the above embodiment, the second connecting part 223 is a pressure arm, one end of the return spring abuts against the drum assembly 100, the other end of the return spring abuts against the pressure arm, and the pressure arm can approach the drum 110 under the action of the return spring, so that the pressure arm can drive the first limiting member 210 to approach the drum 110.

[0048] It is understandable that when the aforementioned tube winding device is winding the tube 300, as the winding layer 310 increases, the first limiting member 210 can move away from the drum 110 under the action of the tube 300. At this time, the second connecting part 223 can move away from the drum 110 under the action of the first limiting member 210. Since one end of the return spring abuts against the drum assembly 100 and the other end of the return spring abuts against the second connecting part 223, when the second connecting part 223 moves away from the drum 110, the end of the return spring that abuts against the second connecting part 223 can move away from the second connecting part 223. Under the action of 23, the end of the return spring that abuts against the drum assembly 100 is close to the return spring, so that the return spring has elastic potential energy. At this time, the elastic potential energy of the return spring is fed back to the first limiting member 210, so that the first limiting member 210 can exert a squeezing effect on the drug delivery tube 300, so as to achieve tight winding of the drug delivery tube 300. When the above-mentioned drug delivery tube release device releases the drug delivery tube 300, as the winding layer 310 decreases, the first limiting member 210 can approach the drum 110 under the action of the elastic potential energy of the elastic return part 221, so as to exert a squeezing and limiting effect on the drug delivery tube 300.

[0049] Continue to refer to Figure 1 as well as Figure 3As shown, the drum assembly 100 also includes two drum supports 120. The drum 110 is disposed between the two drum supports 120, and one end of the drum 110 is rotatably connected to one of the drum supports 120, and the other end of the drum 110 is rotatably connected to the other drum support 120. One end of the second limiting member 220 is connected to one of the drum supports 120, and the other end of the second limiting member 220 is connected to the other drum support 120.

[0050] Specifically, the two ends of the first connecting part 222 are respectively fixed on a drum support 120, and the end of the return spring away from the second connecting part 223 abuts against the drum support 120.

[0051] More specifically, the edge of each drum support 120 protrudes radially from the edge of the drum 110.

[0052] Understandably, the drum support 120 provides support to the drum 110. During the winding and unwinding process of the aforementioned drug delivery tube 300, the drum support 120 ensures the coaxiality of the drum 110 with each rotation. This prevents overlapping loops of the drug delivery tube 300 within the same winding layer 310 during winding and unwinding, thereby improving the stability of the winding and unwinding process. Simultaneously, the two drum supports 120 also limit the movement of the drug delivery tube 300 along the axial direction of the drum 110 during winding and unwinding.

[0053] Reference Figure 2 As shown, there are multiple limiting components 200, which are spaced apart along the circumference of the roll 110 on the roll assembly 100. Each limiting component 200 includes a first limiting member 210. In any two adjacent winding layers 310, when the second winding layer 310 is wound on the first winding layer 310, each first limiting member 210 is pressed against the second winding layer 310, and each first limiting member 210 is pressed against the unwound portion of the first winding layer 310.

[0054] Understandably, the multiple first limiting components 200 can limit the drug delivery tube 300, further making the drug delivery tube 300 more tightly wound during the tube opening and closing process. In any two adjacent winding layers 310, when the second winding layer 310 is wound around the first winding layer 310, since each first limiting member 210 is pressed against the second winding layer 310 and each first limiting member 210 is pressed against the unwound portion of the first winding layer 310, during the process of the second winding layer 310 being wound around the first winding layer 310, each first limiting member 210 can press against the exposed external delivery tube 300 to provide compressive force to the exposed external delivery tube 300, so that the delivery tube 300 is subjected to uniform force at all points along the circumference of the roll 110, further preventing the exposed external delivery tube 300 from detaching during the tube winding and unwinding process, so that the arrangement of the delivery tube 300 during the tube winding and unwinding process is more compact.

[0055] Reference Figure 1 As shown, the first limiting member 210 has a flexible layer 211, which is arranged in the direction close to the roll 110. In any two adjacent winding layers 310, when the second winding layer 310 is wound on the first winding layer 310, the flexible layer 211 is squeezed against the second winding layer 310, and the flexible layer 211 is squeezed against the unwound part of the first winding layer 310.

[0056] Specifically, in the above embodiment, the first limiting member 210 is a flexible pressure roller.

[0057] Understandably, the flexible layer 211 can ensure that the pressure on the delivery tube 300 on each winding layer 310 is relatively uniform, which can prevent some delivery tubes 300 from being under stress or under less stress, prevent the delivery tubes 300 from falling off during the winding and unwinding process, further ensure the tightness of the winding of the delivery tubes 300, and at the same time, prevent some delivery tubes 300 from being crushed due to excessive stress.

[0058] Reference Figure 1 As shown, in the above embodiment, the above-mentioned delivery tube retraction device further includes a feed inlet 600, which is connected to the end of the delivery tube 300 away from the retraction end. The feed inlet 600 is used to input explosives into the delivery tube 300 so as to input explosives into the borehole through the delivery tube 300, and to input explosives into the feed inlet 600 at the same time as retracting the delivery tube 300.

[0059] Reference Figure 2As shown, the tube delivery device also includes a transmission assembly 400. The transmission assembly 400 includes a drive member 410, a first transmission member 420, and a second transmission member 430. The drive member 410 and the first transmission member 420 are chain-driven. The first transmission member 420 and the second transmission member 430 are fixedly connected and coaxially arranged. The second transmission member 430 is chain-driven with the rotating shaft of the drum 110.

[0060] Specifically, in the above embodiments, the driving component 410 can be a drive motor. In addition, in other embodiments, the driving component 410 can also be a drive motor or other driving component 410 capable of driving the shaft to rotate.

[0061] It is understandable that when the driving member 410 drives the first transmission member 420 to rotate in the first direction, the second transmission member 430, which is fixedly connected to the first transmission member 420, can rotate in the first direction under the action of the first transmission member 420. The rotating shaft of the drum 110, which is chain-driven with the second transmission member 430, can rotate in the first direction under the action of the second transmission member 430, so that the rotating shaft of the drum 110 drives the drum 110 to rotate in the first direction, thereby realizing the take-up of the drug delivery tube 300. When the driving member 410 drives the first transmission member 420 to rotate in the second direction, the second transmission member 430, which is fixedly connected to the first transmission member 420, can rotate in the second direction under the action of the first transmission member 420. The rotating shaft of the drum 110, which is chain-driven with the second transmission member 430, can rotate in the second direction under the action of the second transmission member 430, so that the rotating shaft of the drum 110 drives the drum 110 to rotate in the second direction, thereby realizing the release of the drug delivery tube 300.

[0062] Specifically, in the above embodiments, the above-mentioned drug delivery tube take-up and release device further includes a control component (not shown). The control component is electrically connected to the drive component 410. The control component can monitor the rotation speed of the drum 110 in real time, thereby monitoring the take-up and release speed of the drug delivery tube 300. It can also control the power of the drive component 410 in real time through the monitoring data, thereby controlling the take-up and release speed of the drug delivery tube 300.

[0063] Reference Figure 2 as well as Figure 4 As shown, the tube delivery device also includes a tube laying assembly 500, which includes a drive shaft 510, a fixing member 520, and a tube laying member 530. One end of the fixing member 520 is fixed to the drum assembly 100, and the other end of the fixing member 520 is rotatably connected to the drive shaft 510. The tube laying member 530 is sleeved on the drive shaft 510 and can move along the axial direction of the drum 110 on the drive shaft 510. The tube laying member 530 is movably connected to the delivery end of the tube delivery 300, and the delivery end of the tube delivery 300 can move relative to the tube laying member 530 along the circumference of the drum 110.

[0064] Specifically, in the above embodiment, the drive shaft 510 is threadedly connected to the pipe fitting 530.

[0065] More specifically, in the above embodiments, the drive shaft 510 and the pipe assembly 530 form a reciprocating screw.

[0066] It is understood that the fixing member 520 is used to fix the rotating shaft so that a winding space is reserved between the rotating shaft and the drum 110. When the drive shaft 510 rotates, the tube laying member 530 can move along the axial direction of the drive shaft 510 on the rotating shaft, that is, the tube laying member 530 can move along the axial direction of the drum 110. Since the tube laying member 530 is movably connected to the take-up and release end of the drug delivery tube 300, and the take-up and release end of the drug delivery tube 300 can move relative to the tube laying member 530 along the circumferential direction of the drum 110, the drug delivery tube 300 can be wound on the drum 110 along the axial direction and the circumferential direction of the drum 110 through the tube laying member 530 to form the winding layer 310.

[0067] Reference Figure 2 as well as Figure 4 As shown, the transmission assembly 400 also includes a third transmission member 440, which is fixedly connected to the drum 110 and is coaxially arranged with the rotation shaft of the drum 110. The transmission shaft 510 and the third transmission member 440 are chain driven.

[0068] It is understandable that when the driving member 410 drives the first transmission member 420 to rotate, the second transmission member 430, which is fixedly connected to the first transmission member 420, can rotate under the action of the first transmission member 420. The rotating shaft of the drum 110, which is chain-driven with the second transmission member 430, can rotate under the action of the second transmission member 430. The third transmission member 440, which is fixed to the rotating shaft of the drum 110, can rotate. The pipe assembly 500, which is chain-driven with the third transmission member 440, can rotate, so that the transmission shaft 510 can rotate. This allows the pipe assembly 530 to move along the axial direction of the transmission shaft 510 on the rotating shaft. That is, the pipe assembly 530 can move along the axial direction of the drum 110, so that the drug delivery tube 300 can be wound on the drum 110 along the axial direction and circumferential direction of the drum 110 to form a winding layer 310.

[0069] The method for retracting the aforementioned drug delivery tube retractor is as follows:

[0070] The drive component 410 is controlled to rotate, so that the drive component 410 drives the first transmission component 420 to rotate in the first direction;

[0071] The first transmission component 420 drives the second transmission component 430 to rotate in the first direction;

[0072] The second transmission component 430 drives the rotating shaft of the drum 110 to rotate in the first direction;

[0073] The rotating shaft of the drum 110 drives the drum 110 to rotate in the first direction;

[0074] The rotating shaft of the drum 110 drives the transmission shaft 510 to rotate, causing the pipe laying component 530 to move circumferentially along the transmission shaft 510, so as to realize the retraction of the drug delivery pipe 300.

[0075] The method for extending and retracting the aforementioned drug delivery tube is as follows:

[0076] Control the drive component 410 to rotate, so that the drive component 410 drives the first transmission component 420 to rotate in the second direction;

[0077] The first transmission component 420 drives the second transmission component 430 to rotate in the second direction;

[0078] The second transmission component 430 drives the rotating shaft of the drum 110 to rotate in the second direction;

[0079] The rotating shaft of the drum 110 drives the drum 110 to rotate in the second direction;

[0080] The rotating shaft of the drum 110 drives the transmission shaft 510 to rotate, causing the pipe laying component 530 to move circumferentially along the transmission shaft 510, so as to release the drug delivery pipe 300.

[0081] In the above-described tube loading and unloading method, the first transmission member 420 can be driven to rotate by the drive member 410, which in turn drives the second transmission member 430 to rotate. The second transmission member 430 then drives the rotating shaft of the drum 110 to rotate, allowing the drum 110 to rotate. Simultaneously, the rotating shaft of the drum 110 drives the transmission shaft 510 to rotate, causing the tube laying member 530 to move circumferentially along the transmission shaft 510. This allows the tube laying member 530 to lay tubes while the drum 110 is rotating, thereby realizing the loading and unloading of the drug delivery tube 300 in the above-described tube loading and unloading device. This process does not require manual operation and can automate the loading and unloading process of the drug delivery tube 300.
