Description

Technical Field

[0001] This application relates to the field of pipe coating technology, and in particular to a pipe coating suspension device and coating equipment. Background Technology

[0002] The microcatheter used in coronary intervention is coated with a hydrophilic coating at the distal end of the catheter. This hydrophilic coating makes the outer layer of the catheter hydrophilic and lubricating, improving the doctor's operability and significantly reducing friction between the microcatheter and tissue.

[0003] Currently, when coating microcatheters, the catheter seat can be directly clipped onto the coating device. Since the effective length of the microcatheter is generally 110-170cm and the coating distance is relatively long, this method has high space requirements for the coating equipment and is not easy to be compatible with products of various length specifications. Furthermore, when installing and removing the catheter seat, due to the softness of the tubing, slight shaking may cause friction and collision between the tubing bodies, resulting in damage to the surface of the tubing.

[0004] Of course, during microcatheter coating, clamps can also be used to hold the tube in place and fix it to the coating device. While this reduces the space requirements for the coating equipment, the proximal end of the tube is left suspended. Because the tube is flexible and the proximal end is not fixed, shaking during the coating process may cause the proximal end of the tube to bend or fold, resulting in damage to the tube. Utility Model Content

[0005] Therefore, it is necessary to provide a tube coating suspension device and coating equipment to address the problems of easy damage to the tube body and incompatibility with tubes of different lengths during current microcatheter coating. This device can prevent the proximal end of the tube to be coated from being suspended in the air and facilitate the installation of the tube to be coated, thereby reducing the shaking of the tube to be coated and thus reducing the wear of the tube to be coated. At the same time, it can also be compatible with tubes of different lengths to be coated.

[0006] According to one aspect of the present invention, a pipe coating suspension device is provided for suspending pipes to be coated. The pipe coating suspension device includes:

[0014] The mounting base also has a limiting part, which is located on the bottom wall of the opening end and forms an installation entrance with the top wall of the opening end. The first mating part moves into or out of the second mating part through the installation entrance.

[0015] In one embodiment of this application, the connecting part is a hook, which is suspended and installed on the coating equipment; or, the connecting part is a connecting structure, which is snapped into the coating equipment.

[0016] In one embodiment of this application, the first mating part is a groove, the second mating part is a slider, or the first mating part and the second mating part are a snap-fit ​​and snap-slot mating structure.

[0019] The fixing clamp is installed near the second end of the installation pipe.

[0020] In one embodiment of this application, the mounting component has at least two through mounting holes, and the mounting tube is coiled and installed in at least two mounting holes;

[0021] And / or, the multiple mounting components also include at least one mounting clamp, which is disposed on the mounting tube and located between the fixed clamp and the movable clamp of the mounting component;

[0022] And / or, the installation pipe is a rigid plastic pipe;

[0023] And / or, the mounting tube includes at least one first tube body wound once and a second tube body wound less than once, and a plurality of mounting components and connecting pipe clamps are capable of connecting the first tube body and the second tube body to fix the first tube body and the second tube body to form a coiled mounting tube.

[0024] In one embodiment of this application, the pipe coating suspension device further includes a retainer disposed at the second end of the mounting pipe, which fixes the proximal end of the pipe to be coated to the second end of the mounting pipe.

Detailed Implementation

[0038] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0039] See Figures 1 to 3 This application provides a pipe coating suspension device 100. The pipe coating suspension device 100 is used in a coating equipment 10. Figure 1 This is a schematic diagram of a pipe coating suspension device 100 according to an embodiment of this application. Figure 2 for Figure 1The diagram shows the pipe coating suspension device 100 installed in the lifting device 200 within the coating equipment 10. Figure 3 for Figure 2 The enlarged view shows the pipe coating suspension device 100 installed on the lifting device 200.

[0040] The pipe coating suspension device 100 is used to coil and house the proximal end of the pipe 30 to be coated, so that the rest of the pipe 30 is exposed, thereby enabling the coating equipment 10 to apply a coating to the distal end of the pipe 30. In this application, the proximal and distal ends of the pipe 30 are defined according to the usage scenario of the pipe 30. The proximal end of the pipe 30 is the end of the pipe 30 closer to the operator, and the distal end of the pipe 30 is the end of the pipe 30 farther away from the operator.

[0041] Understandably, the pipe 30 to be coated is divided into a proximal end, a middle section, and a distal end along its length. Generally, the proximal end of the pipe 30 is coiled and housed in the pipe coating suspension device 100, while the middle section and distal end of the pipe 30 are exposed within the pipe coating suspension device 100. Alternatively, the proximal end and part of the middle section of the pipe 30 may be coiled and housed within the pipe coating suspension device 100, with the remaining middle section and distal end exposed within the pipe coating suspension device 100. In the subsequent description of the specific structure of the pipe coating suspension device 100, only the proximal end of the pipe 30 to be coated will be coiled and housed within the pipe coating suspension device 100, with the distal end of the pipe 30 exposed within the pipe coating suspension device 100, for ease of description.

[0042] It is worth noting that, in this application, the type of pipe 30 to be coated is not limited in principle. As long as the distal end of the pipe 30 to be coated needs to be coated and the pipe 30 to be coated has a certain degree of flexibility, the pipe coating suspension device 100 of this application can be used to suspend and fix the pipe 30 to be coated so as to facilitate the subsequent coating of the distal end of the pipe 30 to be coated.

[0043] In one embodiment of this application, the tube 30 to be coated is a microcatheter in a medical device. The tube coating suspension device 100 is coiled around and connected to the proximal end of the microcatheter, so that the distal end of the microcatheter is exposed. The microcatheter is fixed to the coating device 10 by the tube coating suspension device 100. The coating device 10 coats the distal end of the microcatheter with a hydrophilic coating to meet the needs of interventional surgery of the microcatheter.

[0044] Of course, in other embodiments of this application, the tube to be coated 30 may also be other types of flexible tubes, and a coating needs to be applied to the distal end of the flexible tube. When describing the specific structure of the tube coating suspension device 100 below, only the example of the tube to be coated 30 being a microcatheter will be used. The fixing principle of the tube to be coated 30 being of other types is essentially the same as the fixing principle of the tube to be coated 30 being a microcatheter, and will not be repeated hereafter. The tube to be coated 30 will be used to represent the microcatheter.

[0045] To better illustrate the specific structure of the pipe coating suspension device 100, the structure of the coating equipment 10 will be briefly described first. (See reference...) Figures 1 to 3 The coating equipment 10 includes at least a lifting device 200, a coating device (not shown), and the pipe coating suspension device 100 of this application. The lifting device 200 is capable of moving vertically ( Figure 2 The lifting device is located below the lifting device 200, and the pipe coating suspension device 100 is installed at the output end of the lifting device 200 after receiving the near end of the pipe 30 to be coated.

[0046] When a coating needs to be applied to the distal end of the pipe 30 to be coated, the lifting device 200 can drive the pipe coating suspension device 100 to lower the pipe 30 to be coated, so that the distal end of the pipe 30 is aligned with the coating device, and the coating device applies the coating to the distal end of the pipe 30. After coating is completed, the lifting device 200 drives the pipe coating suspension device 100 to rise, so that the pipe coating suspension device 100 is disengaged from the coating device.

[0047] Optionally, the coating device is a coating container containing a coating solution. After the lifting device 200 drives the pipe coating suspension device 100 to descend, the distal end of the pipe 30 to be coated can be immersed in the coating container, and its outer surface comes into contact with the coating solution, thus completing the coating of the distal end of the pipe 30. Of course, the coating device can also be a spraying device. After the lifting device 200 drives the pipe coating suspension device 100 to descend, the coating device can spray the coating solution onto the distal end of the pipe 30 to be coated, thus completing the coating of the distal end of the pipe 30. Figure 2 The coating device is not shown; only the coating area A where the coating device is located is shown. The pipe 30 to be coated is coated in the coating area A.

[0048] Optionally, the lifting device 200 includes a lifting drive mechanism (not shown) and a support rod (not shown). The lifting drive mechanism is disposed in the coating equipment 10, and the support rod is disposed at the output end of the lifting drive mechanism. The pipe coating suspension device 100 is mounted on the support rod. The lifting drive mechanism drives the support rod to lift the pipe coating suspension device 100. Optionally, the lifting mechanism is a lifting motor, cylinder, ball screw structure, gear and rack structure, or belt drive structure, etc.

[0049] It is worth noting that the focus of this application is on the structure and connection method of the pipe coating suspension device 100. The specific structure of the lifting device 200, the coating device, and other structures of the coating equipment 10 are not the focus of this application and will not be described further below.

[0050] The pipe coating suspension device 100 of this application can coil around and store the proximal end of the pipe 30 to be coated, so as to avoid the proximal end of the pipe 30 being suspended in the air and to prevent the proximal end of the pipe 30 from bending or folding due to shaking during the coating process. At the same time, after fixing the pipe 30 to be coated to the coating equipment 10, it can also minimize the shaking of the pipe 30 to be coated, thereby avoiding friction and collision between the pipes 30 to be coated, preventing damage to the pipe 30, ensuring the product quality of the pipe 30 to be coated, and also adjusting the coiled length of the pipe 30 to be coated to adapt to pipes 30 of different lengths.

[0051] See Figures 1 to 3 In one embodiment, the pipe coating suspension device 100 includes a mounting pipe 110, a plurality of mounting components 120, a connecting pipe clamp 130, and a suspension component 140. The mounting pipe 110 is coiled, with the proximal end of the pipe 30 to be coated coiled within the mounting pipe 110, and the distal end of the pipe 30 exposed outside the mounting pipe 110. The plurality of mounting components 120 are spaced apart from the mounting pipe 110 and connected to the coiled mounting pipe 110. The connecting pipe clamp 130 is connected to the coiled mounting pipe 110. The suspension component 140 is mounted on the coating equipment 10 and detachably connected to the connecting pipe clamp 130.

[0052] The mounting tube 110 is a hollow tube, allowing the proximal end of the tube 30 to be coated to be inserted into it. Furthermore, the mounting tube 110 is coiled, meaning it can be bent and wound, allowing the tube 30 to be coated to be bent and wound within it. This allows the proximal end of the tube 30 to be coiled and stored within the mounting tube 110, facilitating its storage and reducing the space occupied by the proximal end of the tube 30.

[0053] Furthermore, after the mounting tube 110 is coiled, multiple mounting components 120 are spaced apart on the mounting tube 110 and connected to the coiled mounting tube 110. In this way, the mounting components 120 can fix the mounting tube 110 in place, thus constraining the mounting tube 110 and preventing it from reverting to a straight shape after losing its constraint. In other words, the mounting components 120 are used to fix the coiled mounting tube 110, keeping it in a coiled state, thereby allowing the mounting tube 110 to coil and accommodate the proximal end of the pipe 30 to be coated.

[0054] In this way, the installation tube 110 can coil and store the proximal end of the pipe 30 to be coated, thereby fixing the proximal end of the pipe 30 to be coated and preventing it from being suspended. This way, during the coating process, the proximal end of the pipe 30 is less likely to shake, thus preventing bending or kinking and avoiding damage to the proximal end, ensuring the product quality of the pipe 30.

[0055] Furthermore, with the mounting tube 110 arranged in a coiled shape, the near end of the coiled pipe 30 to be coated can be accommodated within the mounting tube 110. By adjusting the position of the mounting component 120 relative to the mounting tube 110, when the length of the pipe 30 to be coated is long, more of the pipe 30 to be coated can be coiled and accommodated through the mounting tube 110; if the length of the pipe 30 to be coated is short, less of the pipe 30 to be coated can be coiled and accommodated through the mounting tube 110. This allows the pipe coating suspension device 100 to adjust the length of the coiled pipe 30 to be coated through the coiled mounting tube 110.

[0056] In this way, the pipe coating suspension device 100 can fix pipes 30 of different lengths to be coated through the installation pipe 110, thereby adjusting the length of the pipe 30 exposed above the installation pipe 110. This avoids the pipe 30 being exposed too long, which would affect the coating at the far end of the pipe 30. In other words, the pipe coating suspension device 100 is compatible with pipes 30 of different lengths to be coated, making it convenient for the coating equipment 10 to coat pipes 30 of different lengths.

[0057] Furthermore, the mounting tube 110 has a first end 113 and a second end 114 that are disposed opposite to each other. When the pipe 30 to be coated is installed in the mounting tube 110, the proximal end of the pipe 30 to be coated is inserted into the first end 113, and the pipe 30 to be coated is pushed so that the proximal end of the pipe 30 to be coated moves toward the second end 114, so that the proximal end of the pipe 30 to be coated is installed in the mounting tube 110.

[0058] Simultaneously, the cooperation between the connecting pipe clamp 130 and the suspension component 140 enables the mounting pipe 110 to be installed onto the lifting device 200. The connecting pipe clamp 130 also connects to the coiled mounting pipe 110. The suspension component 140 is installed on the lifting device 200 of the coating equipment 10, and the connecting pipe clamp 130 can also connect to the coiled mounting pipe 110. The connecting pipe clamp 130 is detachably installed onto the suspension component 140. It is understood that the form in which the connecting pipe clamp 130 connects to the mounting pipe 110 is substantially the same as that of the mounting component 120, except that the connecting pipe clamp 130 can also be detachably connected to the suspension component 140.

[0059] In this way, after the connecting pipe clamp 130 connects to the coiled installation pipe 110, the connecting pipe clamp 130 can be installed onto the suspension component 140, and then the installation pipe 110 is installed onto the lifting device 200 via the suspension component 140. The lifting device 200 drives the suspension component 140 to move the connecting pipe clamp 130 and the installation pipe 110 up and down synchronously, thereby moving the pipe material 30 to be coated in the installation pipe 110 up and down synchronously, so as to achieve synchronous lifting and lowering of the pipe material 30 to be coated.

[0060] Thus, after the pipe to be coated 30 is coiled and stored by the installation pipe 110, it is installed onto the lifting device 200 by the cooperation of the connecting pipe clamp 130 and the suspension component 140. Specifically, the suspension component 140 is installed onto the lifting device 200, and then the installation pipe 110, which has fixed the pipe to be coated 30, is installed onto the suspension component 140 by the connecting pipe clamp 130. At the same time, when the pipe to be coated 30 is removed from the lifting device 200 after coating, the connecting pipe clamp 130 is also removed from the suspension component 140.

[0061] Because of the detachable connection between the connecting pipe clamp 130 and the suspension component 140, and the initial fixation of the mounting pipe 110 and the mounting component 120 on the pipe to be coated 30, the shaking of the mounting pipe 110 can be minimized when the connecting pipe clamp 130 is installed and removed from the suspension component 140, thereby reducing the shaking of the pipe to be coated 30 in the mounting pipe 110. This can prevent the pipe to be coated 30 from rubbing or colliding with adjacent pipes to be coated 30, thereby preventing damage to the pipe to be coated 30, ensuring the coating effect of the pipe to be coated 30, and thus ensuring the product quality of the pipe to be coated 30.

[0062] When the pipe coating suspension device 100 of this application is installed on the lifting device 200, the suspension component 140 is installed on the lifting device 200, and the pipe to be coated 30 is installed into the installation pipe 110. It is understood that the installation pipe 110 is pre-fixed into a coiled shape by multiple installation components 120 and connecting pipe clamps 130. The proximal end of the pipe to be coated 30 is inserted into the installation pipe 110 and coiled along the installation pipe 110 to achieve the installation of the pipe to be coated 30. Alternatively, the proximal end of the pipe to be coated 30 can be installed into the installation pipe 110 first, and then the installation coil can be coiled and fixed into a coiled shape by multiple installation components 120 and connecting pipe clamps 130. The installation pipe 110, which fixes the pipe to be coated 30, is installed onto the suspension component 140 through the installation component 120. Subsequently, the coating operation can be performed on the distal end of the pipe to be coated 30.

[0063] The pipe coating suspension device 100 of the above embodiment uses multiple mounting components 120 to connect the mounting pipe 110, so that the mounting pipe 110 is arranged in a coiled shape. This coiled arrangement can accommodate the proximal end of the pipe 30 to be coated, preventing the proximal end of the pipe 30 from being suspended in the air and avoiding bending or kinking of the proximal end of the pipe 30 during the coating process. At the same time, a connecting pipe clamp 130 is used to connect the coiled mounting pipe 110 and to the suspension component 140 to fix the pipe 30 to be coated to the coating equipment 10, minimizing the shaking of the pipe 30 to be coated, thereby avoiding friction and collision between the pipes 30 to be coated, preventing damage to the pipe 30, and ensuring the product quality of the pipe 30 to be coated. Furthermore, after the mounting pipe 110 is used to coil and accommodate the proximal end of the pipe 30 to be coated, the length of the coiled pipe 30 can be adjusted to accommodate pipes 30 of different lengths.

[0064] See Figure 1 In one embodiment, the mounting tube 110 includes at least one first tube body 111 wound once and a second tube body 112 wound less than once. A plurality of mounting components 120 and connecting tube clamps 130 can connect the first tube body 111 and the second tube body 112 to fix the first tube body 111 and the second tube body 112 to form a coiled mounting tube 110.

[0065] In this embodiment, after the mounting tube 110 is wound, it will form a first tube body 111 with one loop and a second tube body 112 with less than one loop. Multiple mounting components 120 and connecting tube clamps 130 can connect the first tube body 111 and the second tube body 112 so that the mounting tube 110 remains coiled. That is, the mounting tube 110 is wound in a structure of one and a half loops.

[0066] Of course, in other embodiments of this application, after the mounting tube 110 is wound, it can also form at least two first tube bodies 111 with one loop and a second tube body 112 with less than one loop. Multiple mounting components 120 and connecting tube clamps 130 can connect at least two first tube bodies 111 and second tube bodies 112 to keep the mounting tube 110 coiled. That is, the mounting tube 110 is wound in a structure of at least two and a half loops.

[0067] Understandably, the number of turns of the mounting tube 110 can be selected according to the length of the pipe to be coated 30, thereby adjusting the winding length of the pipe to be coated 30. In this way, the pipe coating suspension device 100 can fix the pipe to be coated 30 of different lengths through the mounting tube 110, avoiding the excessive exposed length of the pipe to be coated 30, which would affect the coating at the far end of the pipe to be coated 30, so that the pipe coating suspension device 100 can be compatible with pipes to be coated 30 of different lengths.

[0068] In one embodiment, the mounting tube 110 is a rigid plastic tube. That is, the mounting tube 110 is made of rigid plastic material, so that the mounting tube 110 can be bent into a coiled shape, while ensuring that the mounting tube 110 has a certain structural strength, so that the mounting tube 110 can fix the tube 30 to be coated, and can indirectly fix the tube 30 to be coated to the suspension component 140.

[0069] See Figure 1 In one embodiment, the plurality of mounting components 120 include at least a fixed clamp 121 and a movable clamp 122 coiled around and connected to the mounting tube 110. The movable clamp 122 is disposed on the mounting tube 110 and is movable toward or away from the first end 113 of the mounting tube 110 to adjust the angle of the first end 113 of the mounting tube 110 relative to the vertical direction. The fixed clamp 121 is disposed near the second end 114 of the mounting tube 110.

[0070] The proximal end of the pipe to be coated 30 passes through the first end 113 of the mounting tube 110 and is installed in the coiled mounting tube 110, and moves toward the second end 114 of the mounting tube 110. The movable tube clamp 122 connects the first tube body 111 and the second tube body 112 of the mounting tube 110 near the first end 113, and the fixed tube clamp 121 connects the first tube body 111 and the second tube body 112 of the mounting tube 110 near the second end 114.

[0071] Thus, the movable clamp 122 and the fixed clamp 121 can fix the coiled mounting tube 110 at the first end 113 and the second end 114 of the mounting tube 110, so that the mounting tube 110 remains coiled, thereby allowing the mounting tube 110 to coil and accommodate the proximal end of the pipe 30 to be coated. Generally, the fixed clamp 121 is fixed near the second end 114 of the mounting tube 110, and the movable clamp 122 moves near the first end 113 of the mounting tube 110.

[0072] Figure 1 The movable pipe clamp 122 shown is located on the left side of the mounting pipe 110. When the movable pipe clamp 122 moves upward, it can release the first end 113 of the mounting pipe 110. At this time, the angle of the first end 113 of the mounting pipe 110 relative to the vertical direction increases. When the movable pipe clamp 122 moves downward, it gradually approaches the first end 113 of the mounting pipe 110, so that the first end 113 of the mounting pipe 110 gradually approaches the mounting pipe 110. At this time, the angle of the first end 113 of the mounting pipe 110 relative to the vertical direction decreases.

[0073] In this way, when the movable pipe clamp 122 moves relative to the mounting pipe 110, the movable pipe clamp 122 can drive the first end 113 of the mounting pipe 110 to move, so that the first end 113 of the mounting pipe 110 is gradually released or gradually close to the mounting pipe 110, thereby adjusting the angle of the first end 113 of the mounting pipe 110 relative to the vertical direction, preventing the distal end of the pipe 30 to be coated from tilting up, so that the distal end of the pipe 30 to be coated is perpendicular to the coating area A, which facilitates the coating of the pipe 30 to be coated, and at the same time, it can also prevent the pipes 30 to be coated from contacting each other.

[0074] In this way, after the movable pipe clamp 122 moves downward, it can bring the first end 113 of the mounting pipe 110 closer to the mounting pipe 110. That is, the length of the mounting pipe 110 protruding from the movable pipe clamp 122 at the first end 113 becomes smaller, and the mounting pipe 110 extends approximately vertically, reducing the swaying of the first end 113 of the mounting pipe 110. After the proximal end of the pipe 30 to be coated is coiled and installed around the mounting pipe 110, the mounting pipe 110 can constrain the angle of the distal end of the pipe 30 to be coated at the first end 113, preventing the distal end of the pipe 30 to be coated from tilting up. At the same time, the swaying of the first end 113 of the mounting pipe 110 is small, thereby reducing the swaying of the distal end of the pipe 30 to be coated.

[0075] See Figure 1 In one embodiment, the plurality of mounting components 120 further include at least one mounting clamp 124, which is disposed on the mounting tube 110 and located between the fixed clamp 121 and the movable clamp 122. The movable clamp 122, the mounting clamp 124, and the fixed clamp 121 are spaced apart circumferentially along the coiled mounting tube 110, thereby achieving reliable fixation of the mounting tube 110, ensuring that the mounting tube 110 is accurately kept in a coiled state, preventing the mounting tube 110 from loosening, and thus achieving reliable storage of the proximal end of the tube 30 to be coated.

[0076] In this embodiment, there is one mounting clamp 124, which is positioned close to the first end 113. Thus, the mounting clamp 124 and the fixing clamp 121 are positioned close to the first end 113 and the second end 114 of the mounting tube 110, respectively, to reliably fix the mounting tube 110 and keep it coiled.

[0077] That is, in this embodiment, the multiple mounting components 120 are a fixed pipe clamp 121, a movable pipe clamp 122, and a mounting pipe clamp 124. Of course, in other embodiments of this application, the number of mounting pipe clamps 124 may also be two, three, or even other numbers.

[0078] See Figure 1In one embodiment, the mounting component 120 has at least two through mounting holes 123, and the mounting tube 110 is coiled and installed in at least two mounting holes 123. After the mounting tube 110 is coiled, the first tube body 111 and the second tube body 112 of the mounting tube 110 extend through the mounting holes 123 respectively. In this way, the inner wall of the mounting hole 123 can limit the first tube body 111 and the second tube body 112, thereby limiting the mounting tube 110 and keeping the mounting tube 110 in a coiled state.

[0079] In this application, the fixed pipe clamp 121, the movable pipe clamp 122, and the mounting pipe clamp 124 all have mounting holes 123. The fixed pipe clamp 121 fixes the mounting pipe 110 through at least two mounting holes 123, the mounting pipe clamp 124 fixes the mounting pipe 110 through at least two mounting holes 123, and the movable pipe clamp 122 fixes the mounting pipe 110 through at least two mounting holes 123. At the same time, the movable pipe clamp 122 can also move along the mounting pipe 110 through the mounting holes 123 to adjust the angle of the first end 113 of the mounting pipe 110 relative to the vertical direction.

[0080] See Figure 1 In this embodiment, the mounting component 120 has three mounting holes 123, and the first tube body 111 and the second tube body 112 of the mounting tube 110 are installed in two of the mounting holes 123 of the mounting component 120. When the mounting tube 110 is wound two and a half turns, the first tube body 111 and the second tube body 112 of the mounting tube 110 can be installed into all three mounting holes 123 simultaneously. Of course, in other embodiments of this application, the mounting component 120 may also be provided with two mounting holes 123 or other numbers of mounting holes 123.

[0081] See Figure 1 In one embodiment, the mounting component 120 is a mounting block, and the mounting block is provided with at least two mounting holes 123. That is, the fixed pipe clamp 121, the movable pipe clamp 122, and the mounting pipe clamp 124 are mounting blocks, and the fixed pipe clamp 121, the movable pipe clamp 122, and the mounting pipe clamp 124 are provided with mounting holes 123. Of course, in other embodiments of this application, the mounting component 120 may also be a tubular structure or other structure, as long as the mounting component 120 is provided with mounting holes 123 to fix the coiled mounting pipe 110.

[0082] See Figure 1 In one embodiment, the connecting pipe clamp 130 includes a first mating portion 131, and the suspension component 140 includes a mounting base 141 and a connecting portion 142. The connecting portion 142 is disposed on the mounting base 141 and suspended on the coating equipment 10. The mounting base 141 has a second mating portion 1411, and the first mating portion 131 is detachably mounted on the second mating portion 1411.

[0083] Mounting base 141 supports connecting part 142, which can be connected to lifting device 200 so that suspension component 140 can be installed on lifting device 200. Connecting pipe clamp 130 has a first mating part 131 at one end facing suspension component 140, and mounting base 141 has a second mating part 1411 at one end facing connecting pipe clamp 130. The first mating part 131 and the second mating part 1411 are detachably connected, thereby realizing a detachable connection between connecting pipe clamp 130 and mounting base 141.

[0084] When the pipe coating suspension device 100 of this application is installed onto the lifting device 200, the connecting part 142 is installed onto the lifting device 200, and then the proximal end of the pipe 30 to be coated is coiled and installed onto the mounting pipe 110. Subsequently, the first mating part 131 is installed onto the second mating part 1411, thereby enabling the mounting pipe 110 to be installed onto the lifting device 200 via the connecting pipe clamp 130, the mounting base 141, and the connecting part 142. Moreover, during disassembly, the first mating part 131 can be directly removed from the second mating part 1411.

[0085] Thus, through the detachable connection between the first mating part 131 and the second mating part 1411, the quick installation and disassembly of the connecting pipe clamp 130 and the mounting base 141 can be achieved. At the same time, the stability of the installation and disassembly between the connecting pipe clamp 130 and the mounting base 141 can be ensured, minimizing the shaking of the mounting pipe 110 during installation and disassembly, thereby avoiding affecting the coating effect of the pipe 30 to be coated and ensuring the product quality of the pipe 30 to be coated.

[0086] In one embodiment, the connecting portion 142 and the mounting base 141 are an integral structure. This ensures the structural strength between the connecting portion 142 and the mounting base 141, preventing breakage at the connection point. Of course, in other embodiments of this application, the connecting portion 142 and the mounting base 141 may also be designed separately and reliably connected by threaded components or the like.

[0087] See Figure 1 In one embodiment of this application, the connecting part 142 is a hook, which is suspended and installed on the coating equipment 10. The hook is a U-shaped constriction piece, so that the hook can be reliably installed on the lifting device 200, preventing the hook from swaying relative to the lifting device 200 when the lifting device 200 drives the pipe coating suspension device 100 to rise and fall, and ensuring that the pipe coating suspension device 100 is reliably fixed to the lifting device 200. Of course, in other embodiments of this application, the connecting part 142 is a connecting structure, such as a knob and connecting ring mating structure, etc.

[0088] See Figure 1In one embodiment, the connecting pipe clamp 130 further has at least two through-holes 132, and the mounting pipe 110, after being coiled, can be installed in at least two connecting holes 132. The first pipe body 111 and the second pipe body 112 of the mounting pipe 110 can be respectively installed into the mounting holes 123 of the connecting pipe clamp 130. In this way, the two connecting holes 132 can constrain the mounting pipe 110 so that the mounting pipe 110 remains coiled.

[0089] See Figure 1 and Figure 4 In one embodiment of this application, the first mating part 131 is a slider, and the second mating part 1411 is a groove. The second mating part 1411 has an open end 14111 and a closed end 14112 that are disposed opposite to each other. The first mating part 131 is slidably installed in the second mating part 1411 through the open end 14111. Figure 4 for Figure 1 A cross-sectional view of the suspension component 140 at the second mating part 1411 in the pipe coating suspension device 100 shown.

[0090] In other words, the mounting base 141 is recessed towards the surface of the connecting pipe clamp 130, forming a second mating part 1411 as a sliding groove. Furthermore, one end of the second mating part 1411 is an open end 14111, and the other end is a closed end 14112. The first mating part 131 can slide into the second mating part 1411 from the open end 14111, and the closed end 14112 can limit the first mating part 131, preventing it from slipping off from the other end of the second mating part 1411, thus ensuring that the first mating part 131 is reliably installed into the second mating part 1411.

[0091] See Figure 1 and Figure 4 In one embodiment, the mounting base 141 further includes a limiting portion 143, which is located on the bottom wall of the opening end 14111 and forms an installation entrance with the top wall of the opening end 14111. The first mating portion 131 moves into or out of the second mating portion 1411 through the installation entrance. The limiting portion 143 is disposed at the opening end 14111 of the second mating portion 1411, and is located below the opening end 14111, with a certain distance between it and the top wall of the opening end 14111, which is the installation entrance.

[0092] The first mating part 131 can be moved into the second mating part 1411, which is a groove, through the installation inlet. When the first mating part 131 is located in the second mating part 1411, under the gravity of the mounting tube 110 and the tube to be coated 30, the first mating part 131 can fit against the bottom of the second mating part 1411. At the same time, the two ends of the first mating part 131 can abut against the closed end 14112 and the limiting part 143 of the second mating part 1411.

[0093] In this way, the closed end 14112 of the second mating part 1411 and the limiting part 143 can limit the first mating part 131, preventing the first mating part 131 from sliding out of the second mating part 1411 and ensuring that the first mating part 131 is reliably installed in the second mating part 1411. Moreover, when it is necessary to remove the first mating part 131 from the second mating part 1411, the mounting tube 110 is raised so that the first mating part 131 is aligned with the mounting inlet, and then the second mating part 1411 can be removed through the mounting inlet.

[0094] Thus, through the sliding fit between the first mating part 131 and the second mating part 1411, the installation and disassembly of the connecting pipe clamp 130 and the suspension component 140 are realized. The entire installation and disassembly process is smooth, which can minimize the shaking of the installation pipe 110, thereby avoiding contact and friction between the pipes 30 to be coated due to shaking, and thus avoiding affecting the coating effect of the pipes 30 to be coated.

[0095] In one embodiment, the second mating part 1411 includes a first slide groove 14113 and a second slide groove 14114 that communicate with each other. The first slide groove 14113 is located above the second slide groove 14114, and the width of the first slide groove 14113 is greater than the width of the second slide groove 14114. The first mating part 131 includes a first slider (not shown) and a second slider (not shown). The first slider is disposed above the second slider, and the width of the first slider is greater than the width of the second slider.

[0096] The width dimension here refers to the dimension perpendicular to the sliding direction of the first mating part 131, that is... Figure 4 The dimensions in the left-right direction are shown. The width of the first slider is adapted to the width of the first slide groove 14113, and the width of the second slider is adapted to the width of the second slide groove 14114. When the first mating part 131 is installed on the second mating part 1411, the first slider is slidably disposed in the first slide groove 14113, and the second slider is slidably disposed in the second slide groove 14114.

[0097] In this way, a limiting step can be formed at the connection between the first slide groove 14113 and the second slide groove 14114. The bottom wall of the first slider can be located at the limiting step, and the second slider can be located in the second slide groove 14114, so as to limit the installation of the first mating part 131 on the second mating part 1411 and prevent the first mating part 131 from moving along the second mating part 1411. Figure 1 The vertical direction is disengaged from the second mating part 1411.

[0098] In one embodiment, the limiting portion 143 is a limiting protrusion. Further, there are two limiting protrusions, symmetrically arranged in the first slide groove 14113. The width between the two limiting protrusions is smaller than the width of the second slide groove 14114, so that the second slider can pass through the channel between the two limiting protrusions and be installed in the second mating portion 1411. Of course, the number of limiting protrusions can also be one.

[0099] Of course, in other embodiments of this application, the shapes of the first mating part 131 and the second mating part 1411 can also be interchanged, that is, the first mating part 131 is a sliding groove and the second mating part 1411 is a slider; or, the first mating part 131 and the second mating part 1411 are a latching and slot mating structure, and pressing the latch causes the first mating part 131 and the second mating part 1411 to be latched together or disassembled.

[0100] See Figure 1 and Figure 5 In one embodiment, the pipe coating suspension device 100 further includes a retainer 150, which is disposed at the second end 114 of the mounting pipe 110 and fixes the proximal end of the pipe 30 to be coated to the second end 114 of the mounting pipe 110. Figure 5 for Figure 1 An exploded view of the fixture 150 in the pipe coating suspension device 100 shown.

[0101] A retainer 150 is disposed at the second end 114 of the mounting tube 110 to fix the proximal end of the pipe 30 to be coated to the mounting tube 110. The proximal end of the pipe 30 to be coated passes through the first end 113 of the mounting tube 110 and is installed into the mounting tube 110, moving towards the second end 114. When the proximal end of the pipe 30 to be coated moves to the second end 114, the proximal end of the pipe 30 to be coated can be installed in the retainer 150. After the retainer 150 is tightened, it can fix the proximal end of the pipe 30 to be coated to the mounting tube 110, preventing the pipe 30 to be coated from sliding relative to the mounting tube 110 and ensuring the coating effect of the distal end of the pipe 30 to be coated.

[0102] See Figure 1 and Figure 5 In one embodiment, the retainer 150 includes a retaining body 151, a retaining core 152, and a retaining cap 153. The retaining body 151 is disposed at the second end 114 of the mounting tube 110. The retaining core 152 is disposed in the retaining body 151 and can expand or contract radially along the retaining body 151. The retaining cap 153 is rotatably disposed on the retaining body 151. When the retaining cap 153 is tightened relative to the retaining body 151, it can cause the retaining core 152 to contract radially along the retaining body 151 to clamp the proximal end of the tube 30 to be coated.

[0103] Both the fixing body 151 and the fixing liner 152 are hollow. The fixing body 151 has a first channel (not shown), and the fixing liner 152 has a second channel (not shown). The first channel and the second channel are connected in sequence to form an installation channel. The proximal end of the pipe to be coated 30 moves from the first end 113 to the second end 114 of the mounting pipe 110, and then passes through the first channel and is installed in the second channel.

[0104] The fixing body 151 is fixedly installed at the second end 114 of the mounting tube 110. The fixing core 152 is a component for fixing the pipe 30 to be coated, and the fixing core 152 is installed in the first channel of the fixing body 151. The fixing cap 153 is screwed to the fixing body 151, and is pushed to move the fixing core 152 into or out of the fixing body 151, thereby allowing the fixing core 152 to contract or expand radially along the fixing body 151.

[0105] When the retainer 150 is used to fix the pipe 30 to be coated, the proximal end of the pipe 30 to be coated moves from the first end 113 to the second end 114 of the mounting tube 110, and then the proximal end of the pipe 30 to be coated passes through the fixing body 151 and is installed in the fixing core 152. Subsequently, the fixing cap 153 is tightened in the fixing body 151. The fixing cap 153 can gradually press the fixing core 152 into the fixing body 151, so that the fixing core 152 contracts radially to clamp the proximal end of the pipe 30 to be coated, thereby fixing the proximal end of the pipe 30 to be coated to the mounting tube 110.

[0106] When releasing the pipe to be coated 30, the fixing cap 153 is loosened from the fixing body 151. At this time, the fixing cap 153 is detached from the fixing body 151, and the fixing core 152 can gradually move out of the fixing body 151 and expand radially along the fixing body 151 to release the pipe to be coated 30. At this time, the pipe to be coated 30 can be removed from the fixing core 152, the fixing body 151 and the mounting tube 110, realizing the disassembly of the pipe to be coated 30.

[0107] See Figure 5 In one embodiment, the fixing body 151 has a fastening hole (not shown) at one end facing the fixing core 152. The fixing core 152 has a plurality of circumferentially spaced fixing segments 1521, with adjacent fixing segments 1521 having a gap in the circumferential direction. When the fixing cap 153 is tightened, the fixing cap 153 can gradually press the plurality of fixing segments 1521 into the fastening hole. The inner wall of the fastening hole gradually squeezes the plurality of fixing segments 1521, causing the plurality of fixing segments 1521 to contract radially along the fixing body 151, thereby enabling the plurality of fixing segments 1521 to clamp the pipe 30 to be coated. Optionally, the fixing cap 153 is a nut, and the fixing body 151 has an external thread that mates with the nut.

[0108] The pipe coating suspension device 100 of this application uses a coiled installation tube 110 to coil and store the proximal end of the pipe 30 to be coated, thus fixing the proximal end of the pipe 30 to be coated and preventing it from being suspended in the air. In this way, during the coating process at the distal end of the pipe 30, the proximal end of the pipe 30 to be coated is less likely to shake, thereby preventing bending or kinking of the proximal end of the pipe 30 to be coated, and thus preventing damage to the proximal end of the pipe 30, ensuring the product quality of the pipe 30 to be coated.

[0109] Meanwhile, the installation tube 110 is connected by a fixed tube clamp 121, a movable tube clamp 122, and an installation tube clamp 124 to keep the installation tube 110 coiled, preventing it from loosening and achieving coiled storage of the near end of the pipe 30 to be coated. Adjusting the positions of the fixed tube clamp 121, the movable tube clamp 122, and the installation tube clamp 124 allows adjustment of the winding length of the pipe 30 to be coated, enabling the pipe coating suspension device 100 to accommodate pipes 30 of different lengths, facilitating coating of pipes 30 of different lengths by the coating equipment 10. Adjusting the position of the movable tube clamp 122 also allows adjustment of the angle of the first end 113 of the installation tube 110 relative to the vertical direction, preventing the far end of the pipe 30 to be coated from tilting up and ensuring that the far end of the pipe 30 to be coated is perpendicular to the coating area A.

[0110] Furthermore, the suspension component 140 and the connecting pipe clamp 130 are separately configured, allowing the suspension component 140 to be installed on the lifting device 200 first, and then the mounting pipe 110 for mounting the pipe to be coated 30 to be slidably installed into the mounting base 141 via the connecting pipe clamp 130. This prevents the shaking of the pipe coating suspension device 100 during installation and removal from the lifting device 200 from affecting the coating effect of the pipe to be coated 30. Moreover, the closed end 14112 of the second mating part 1411 and the limiting part 143 limit the first mating part 131, preventing the shaking of the mounting pipe 110 caused by the shaking during the lifting process of the lifting device 200, thus ensuring the coating effect of the pipe to be coated 30. At the same time, the near end of the pipe to be coated 30 is fixed to the second end 114 of the mounting pipe 110 by the fixing device 150, preventing the pipe to be coated 30 from moving relative to the mounting pipe 110 during the coating process.

[0111] In use, the pipe coating suspension device 100 of this application involves inserting the proximal end of the pipe 30 to be coated through the first end 113 of the mounting tube 110 and moving it toward the second end 114 to install the proximal end of the pipe 30 into the retainer 150. Then, the retaining cap 153 of the pipe 30 is tightened to fix the proximal end of the pipe 30 to the proximal end of the mounting tube 110, thereby fixing the pipe 30 into the mounting tube 110. Subsequently, the position of the movable pipe clamp 122 is adjusted so that the angle of the first end 113 of the mounting tube 110 relative to the vertical direction makes the distal end of the pipe 30 perpendicular to the ground.

[0112] The suspension component 140 is installed onto the lifting device 200 via the connecting part 142. Then, the first mating part 131 is slid into the second mating part 1411 through the installation inlet to install the mounting tube 110, which holds the pipe to be coated 30, onto the suspension component 140. The coating equipment 10 is operated, and the lifting device 200 drives the pipe coating suspension device 100 to descend, coating the distal end of the pipe 30 to be coated. After coating is completed, the lifting device 200 drives the pipe coating suspension device 100 to rise, loosens the fixing nut of the retainer 150, and pulls the proximal end of the pipe 30 to be coated from the first end 113 of the mounting tube 110.

[0113] The pipe coating suspension device 100 of this application changes the winding distance of the pipe 30 to be coated by adjusting the relative position of the fixing pipe clamp 121 and the mounting pipe 110. It is compatible with pipes 30 of various lengths, enabling one coating equipment 10 to be compatible with multiple product specifications without the need for additional tooling, thus saving development costs. Moreover, the separate design of the suspension component 140 and the mounting pipe 110 avoids scratches on the pipe 30 or coating caused by shaking during installation and removal from the coating equipment 10, thereby improving the yield of the pipe 30 to be coated.

[0114] See Figures 1 to 3 This application also provides a coating apparatus 10, including a lifting device 200, a coating device, and at least one pipe coating suspension device 100 as described in any of the above embodiments. The coating device is located below the lifting device 200, and the pipe coating suspension device 100 is disposed on the lifting device 200 and fixes the pipe 30 to be coated. The lifting device 200 drives the pipe coating suspension device 100 to rise and fall, so that the coating device applies a coating to the distal end of the pipe 30 to be coated.

[0115] In this embodiment, there are multiple pipe coating suspension devices 100, each suspending one pipe 30 to be coated. In this way, the coating equipment 10 can coat the distal ends of multiple pipes 30 to be coated at the same time. At the same time, the slidable connection between the suspension component 140 and the connecting pipe clamp 130 facilitates the installation and removal of the installation pipe 110, avoiding scratches on the pipe 30 or coating caused by shaking during installation and removal from the coating equipment 10, thereby improving the yield of the pipes 30 to be coated.

[0116] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0117] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
