Description

Technical Field

[0001] The present invention relates to the technical field of pipeline transportation equipment, in particular to a port-supported pipeline transportation device. Background Art

[0002] The exterior surfaces of pipes, such as centrifugally cast pipes, are often painted to enhance their corrosion resistance. The painted pipes are then transported to the next workstation by a conveyor system, where they are dried during transport. Existing conveyor systems typically support the bottom of the pipe using supports such as V-grooves and conveyor belts. However, the large contact area between the outer wall of the pipe and the support system can easily cause extensive damage and shedding of the uncured coating on the outer wall. This increases the workload for subsequent manual repainting and impacts the overall production efficiency of the pipe product.

[0003] Patent publication number CN222845857U discloses a pipe support and conveying device, comprising a conveying device and a support adjustment device, the latter comprising a telescopic column and a controller. The telescopic column extends to support the outer wall of the pipe, preventing direct contact between the pipe and the V-shaped groove of the conveyor chain, which could damage the coating and effectively reduce the contact area between the pipe and the conveyor. Once the coating on the pipe's outer wall solidifies, the controller retracts the telescopic column, lowering its top surface below the slope of the V-shaped groove. This allows the pipe to rest on the V-shaped groove of the conveyor chain and proceed to the next process.

[0004] But it has the following problems:

[0005] 1. The telescopic column cannot limit the axial position of the pipeline, which may lead to the risk of axial movement of the pipeline;

[0006] 2. The supporting point of the telescopic column for the pipe is located on the circumference of the pipe, which makes it difficult to repaint. Even after repainting, the outer surface of the pipe may still be unsightly. Summary of the Invention

[0007] The purpose of the present invention is to provide a port-supported pipeline conveying device to solve the problems in the prior art that the coating on the circumferential surface is easily damaged during pipeline conveyance and the axial position of the pipeline cannot be limited.

[0008] In order to achieve the above-mentioned object, the present invention provides a port-supported pipeline conveying device, which includes a chain plate conveying mechanism and a supporting mechanism.

[0009] The chain conveying mechanism includes a plurality of chain members configured to circulate along an annular track.

[0010] The supporting mechanism includes supporting members arranged at both ends of the chain plate member. The upper end of the supporting member is provided with an inclined surface for contacting and cooperating with the pipeline port to support it. The inclined surfaces of the supporting members at both ends of the chain plate member are arranged facing each other. When the pipeline is placed on the supporting member, it can be subjected to the inward restraining force from the inclined surfaces of the supporting members at both ends of the chain plate member.

[0011] In an optional implementation, the support mechanism further includes a mounting plate, the mounting plate is connected to the chain plate member, and the support member is connected to the mounting plate.

[0012] In an optional implementation, the mounting plate is fixedly mounted on the chain plate member.

[0013] In an optional implementation, the installation position of the mounting plate on the chain plate member is adjustable, the chain plate member has an inner cavity, the chain plate member is specifically a rectangular tube, the chain plate member is provided with a movable opening connected to the inner cavity, and the chain plate member is provided with multiple positioning holes along its length direction; the support mechanism also includes a slider and a fixing screw, the slider is slidably connected to the inner cavity of the chain plate member, the upper end of the slider is fixedly connected to the mounting plate, the slider is provided with an internal threaded hole, and the slider is fixedly connected to the chain plate member by a fixing screw that passes through the positioning hole and is threadedly connected to the internal threaded hole.

[0014] In one optional implementation, the support member is fixedly mounted on the mounting plate. Specifically, the support member can be securely fastened to the mounting plate by welding, bolting, or other means to prevent relative displacement between the support member and the mounting plate. This ensures that the support member can stably support the pipeline, enhances the overall stability of the support mechanism, and enables the support member to reliably limit and support the pipeline during transportation.

[0015] In one optional implementation, two support members are provided at each end of the chain plate. This results in a total of four support members, which collectively support the pipe port and distribute the weight of the pipe. The two support members at each end cooperate with each other to further enhance the pipe's position-limiting effect, improving its support strength and stability, preventing the pipe from falling or tilting due to insufficient support during transportation, while also better limiting the pipe's lateral and longitudinal movement.

[0016] In an optional implementation, the support members at both ends of the chain plate are arranged in two groups, and each group has two support members; one group of support members is located between the other group of support members and is lower in height than the other group of support members.

[0017] In an optional implementation, the support mechanism also includes a connecting rod, a screw, a nut seat, a worm gear reducer, and a connecting plate. The support member is hinged to the mounting plate, the worm gear reducer is fixedly connected to the mounting plate, the screw is rotationally connected to the mounting plate, the screw is transmission-connected to the output end of the worm gear reducer, the nut seat is threadedly connected to the screw, one end of the connecting rod is hinged to the end of the support member away from the inclined surface, and the other end of the connecting rod is hinged to the nut seat.

[0018] In an optional implementation, automatic adjustment mechanisms are provided on both sides of the chain conveying mechanism, and the automatic adjustment mechanisms include a mounting frame, a power push rod, a push plate, and a rack. The mounting frame is installed on the frame, the power push rod is installed on the mounting frame, the output end of the power push rod is fixedly connected to the push plate, and the push plate is fixedly connected to the rack; the support mechanism also includes a gear, which is fixedly mounted on the input shaft of the worm gear reducer; the rack can be moved to the circular motion path of the gear under the drive of the power push rod, and is used to engage with the gear.

[0019] In an optional implementation, the chain conveying mechanism includes a frame, a driving shaft, a driven shaft, a driving motor, a driving sprocket, a driven sprocket, a chain, a chain guide, and a fixed frame. The driving shaft and the driven shaft are both rotatably connected to the frame, the driving motor is fixedly connected to the frame, the output end of the driving motor is transmission-connected to the driving shaft, the driving sprocket is fixedly mounted on the driving shaft, the driven sprocket is fixedly mounted on the driven shaft, the driving sprocket and the driven sprocket are connected through a chain transmission, the chain plate is fixedly mounted on the chain through a fixed frame, the chain guide is fixedly mounted on the frame and is used to support the chain, and the chain is in contact with the chain guide.

[0020] The beneficial effects of this technical solution are as follows: by arranging support members with inclined surfaces facing each other at both ends of the chain plate members, and utilizing the structure of the inclined surfaces, the pipeline generates an interaction force with the inclined surfaces under the action of gravity, forming an inward constraint on the pipeline, limiting the lateral movement of the pipeline, and being able to stably support and limit the pipeline to ensure stable conveying work; at the same time, the support members only contact the pipeline ports, which can avoid damage to the coating on the outer surface of the pipeline. Subsequently, only the ports need to be repainted, and the repainting operation is more convenient. The effect of the port repainting is better and more beautiful, which can avoid the situation where the outer surface of the pipeline is unsightly due to repainting.

DETAILED DESCRIPTION

[0041] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0042] Example 1: Please refer to Figures 1 to 3 , an embodiment of the present application provides a port-supported pipeline conveying device, including a chain conveying mechanism 1 and a supporting mechanism 2.

[0043] The chain conveying mechanism 1 includes a frame 12 , a driving shaft 13 , a driven shaft 14 , a driving motor 15 , a driving sprocket 16 , a driven sprocket, a chain 17 , a chain 17 guide 18 , a fixing frame 19 and a chain plate 11 .

[0044] Among them, the driving shaft 13 and the driven shaft 14 are both rotatably connected to the frame 12, the driving motor 15 is fixedly connected to the frame 12, the output end of the driving motor 15 is transmission-connected to the driving shaft 13 through a coupling, the driving sprocket 16 is fixedly mounted on the driving shaft 13, the driven sprocket is fixedly mounted on the driven shaft 14, the driving sprocket 16 and the driven sprocket are both provided with two, the driving sprocket 16 and the driven sprocket are transmission-connected by a chain 17, the chain 17 is a chain with accessories 17, the chain plate 11 is fixedly mounted on the chain 17, the chain 17 guide 18 is fixedly mounted on the frame 12 and is used to support the chain 17, and the chain 17 is in contact with the chain 17 guide 18.

[0045] Drive motor 15 provides power, driving drive shaft 13 to rotate. Drive sprocket 16 on drive shaft 13 drives driven sprocket 16 via chain 17, causing chain 17 to circulate. Chain guide 18 supports and guides chain 17, ensuring it moves along a predetermined trajectory. Consequently, chain plate member 11 mounted on chain 17 is configured to circulate along a circular trajectory. The entire chain plate conveying mechanism 1 features a compact structure and stable transmission, enabling reliable circular motion of chain plate member 11, providing a stable power and motion trajectory for pipeline transportation.

[0046] The support mechanism 2 includes support members 21 disposed at both ends of the chain plate member 11. The support members 21 are directly fixedly connected to the chain plate member 11. Specifically, the fixed connection method can be achieved by welding. The method of directly fixing the support members 21 to the chain plate member 11 is simple in structure and low in cost.

[0047] The upper ends of the supports 21 are provided with inclined surfaces 211 for contacting and supporting the pipe ports. The inclined surfaces 211 of the supports 21 at both ends of the chain plate 11 face each other. When the pipe is placed on the supports 21, it is subject to an inward restraining force from the inclined surfaces 211 of the supports 21 at both ends of the chain plate 11. This inward restraining force specifically refers to the restraining force acting toward the center of the area enclosed by the supports 21 at both ends of the chain plate 11.

[0048] The support members 21 at both ends of the chain plate member 11 can be arranged in n groups, each group having two support members 21, where n is a positive integer.

[0049] In this embodiment, Figure 1 As shown, n is set equal to 1, that is, only one set of support members 21 is provided at one end of the chain plate member 11. The total number of support members 21 on the chain plate member 11 is four. These four support members 21 jointly support the pipe end, distributing the weight of the pipe. Simultaneously, the two support members 21 at each end cooperate with each other. Utilizing the structure of the inclined surface 211, the pipe generates an interaction force with the inclined surface 211 under the action of gravity. Since the inclined surfaces 211 of the support members 21 at both ends face each other, they form an inward constraint on the pipe, further enhancing the pipe's positional limitation, improving the pipe's support strength and stability, and preventing the pipe from falling or tilting due to insufficient support during transportation. This also better limits the pipe's lateral and longitudinal movement. Furthermore, the support members 21 only contact the pipe end, thus avoiding damage to the pipe's outer surface coating.

[0050] However, the maximum spacing between the two support members 21 at the same end is limited by the width of the chain plate 11. If the chain plate 11 is wider, the overall cost increases. If the chain plate 11 is narrower, the maximum spacing between the two chain plates 11 does not exceed the width of the chain plate 11, and the maximum diameter of the pipe that can be adapted is smaller.

[0051] In other embodiments, when n is greater than 1, the spacing between the two support members 21 in each group of support members 21 is different, and therefore the models of the pipes adapted for support are also different. A group of support members 21 at appropriate positions can be selected according to the diameter of the pipe, so that each group of support members 21 at both ends of the chain plate member 11 supports the pipe.

[0052] In both the prior art method of supporting the circumferential surface of the pipe and the port support method in this embodiment, the support points need to be repainted later. However, the repainting effect of the circumferential surface support points is poor. Specifically, the support points of the circumferential surface support method are located on the arc surface of the cylindrical surface of the pipe. Support debris and oil stains are easily retained on the edge of the arc surface, making it difficult to clean. The arc surface needs to be repainted evenly along the curved surface. Manual operation is prone to uneven thickness and sagging. During mechanical spraying, the curvature of the arc surface may make it difficult to accurately match the spray gun angle, resulting in missed spraying or accumulation. After the arc surface is repainted, the paint-repaired area of ​​the arc surface support point is different from the spraying angle and thickness of the original coating, and color difference may occur. After repainting, the boundary is difficult to naturally transition with the original coating, resulting in a "patch" visual effect.

[0053] The support point of the port support is located at the pipe port. The port area is easy to clean centrally, with fewer impurities on the surface, making spraying or brushing operations simpler. The paint touch-up point is located at the port, and the repair marks are not easily noticeable to the naked eye.

[0054] To facilitate installation of the chain 17 and maintain its tension, a driving shaft 13 is rotatably connected to the frame 12 via bearings. Two symmetrically arranged track bearing plates are mounted on the frame 12. A slider bearing is slidably mounted between the two track bearing plates. The driven shaft 14 is rotatably connected to the slider bearing. A nut is fixedly mounted on the frame 12, and an adjusting screw is threadedly mounted on the nut. One end of the adjusting screw abuts against the slider bearing. By rotating the adjusting screw, guided by the track bearing plates, the adjusting screw pushes the slider bearing away from the nut, thereby increasing the spacing between the driving shaft 13 and the driven shaft 14, thereby adjusting the tension of the chain 17.

[0055] Example 2: Please refer to Figure 4 This embodiment is roughly the same as embodiment 1, except that the support member 21 and the chain plate member 11 are not directly connected, but indirectly connected. Specifically, the support mechanism 2 also includes a mounting plate 22, and the mounting plate 22 is fixedly connected to the chain plate member 11, and the support member 21 is fixedly connected to the mounting plate 22, thereby realizing an indirect fixed connection between the support member 21 and the chain plate member 11.

[0056] The mounting plate 22 serves as an intermediate connector, connecting the support member 21 to the chain member 11, allowing the support member 21 to be fixed to the chain member 11, thereby supporting the pipeline. Furthermore, the installation of the mounting plate 22 allows the two support members 21 at the same end of the chain member 11 to maintain a large distance between them, regardless of the width of the chain member 11.

[0057] In addition, the mounting plate 22 is fixedly mounted on the chain plate member 11. Specifically, the mounting plate 22 can be fixed by welding, riveting, bolting, etc., so that the mounting plate 22 is firmly mounted on the chain plate member 11, so that the mounting plate 22 and the chain plate member 11 form a stable integral structure.

[0058] The position of the mounting plate 22 on the chain plate 11 is fixed, thereby ensuring the stability of the position of the support member 21, making the support and limiting effect of the support mechanism 2 on the pipeline more reliable, and is suitable for scenarios with high requirements on the pipeline transportation position accuracy.

[0059] Example 3: Please refer to Figure 5 and Figure 6 This embodiment is substantially the same as embodiment 2, except that the mounting plate 22 is not fixedly mounted on the chain plate member 11. To facilitate the transport of pipes of varying lengths, the mounting position of the mounting plate 22 on the chain plate member 11 is adjustable. The chain plate member 11 has an inner cavity, specifically a rectangular tube. A movable opening 111 communicating with the inner cavity is provided on the chain plate member 11, and a plurality of positioning holes 112 are provided on the chain plate member 11 along its length. The support mechanism 2 further includes a slider 23 and a fixing screw 24. The slider 23 is slidably connected to the inner cavity of the chain plate member 11. The upper end of the slider 23 is fixedly connected to the mounting plate 22. The slider 23 is provided with an internal threaded hole. The slider 23 is fixedly connected to the chain plate member 11 via a fixing screw 24 that passes through the positioning hole 112 and is threadedly connected to the internal threaded hole. The slider 23 is connected to the mounting plate 22 via a connecting bolt that passes through the movable opening 111.

[0060] When the position of the mounting plate 22 needs to be adjusted, the fixing screws 24 are loosened, and the slider 23 can slide along the length direction of the inner cavity of the chain plate 11, driving the mounting plate 22 to move to the appropriate position. The fixing screws 24 are then tightened to fix the slider 23 to the chain plate 11 through the positioning holes 112. In this way, the position of the mounting plate 22 can be flexibly adjusted according to pipes of different diameters, and the position of the support member 21 can be adjusted to meet the support requirements of pipes of different lengths and specifications, greatly improving the applicability of the device.

[0061] Furthermore, a support member 21 is fixedly mounted on the mounting plate 22. Specifically, the support member 21 can be firmly fixed to the mounting plate 22 by welding, bolting, or the like, ensuring that there is no relative displacement between the support member 21 and the mounting plate 22, ensuring that the support member 21 can stably support the pipeline, enhancing the overall stability of the support mechanism 2, and enabling the support member 21 to reliably limit and support the pipeline during transportation.

[0062] Example 4: Please refer to Figure 7 and Figure 8 This embodiment is substantially the same as Embodiment 2, except that one end of the chain plate 11 is not provided with only one set of support members 21. To further optimize device performance, two sets of support members 21 are provided at each end of the chain plate 11, each set containing two support members 21; one set of support members 21 is located between the other set of support members 21 and is lower in height than the other set of support members 21.

[0063] Two groups of support members 21 of different heights form a stepped staggered layout. When transporting smaller diameter pipes, the lower height support members 21 can be used to accurately support the pipe ports; when transporting larger diameter pipes, the larger diameter pipes will cross the lower height support members 21 and be supported by the higher height support members 21. Through this high and low matching and staggered setting method, adaptive support for pipes of different diameters can be achieved.

[0064] By setting two groups of support members 21 with different heights and staggered distribution, pipes of various diameters can be quickly adapted without adjusting the position or angle of the support members 21, which significantly improves the versatility of the device for pipes of different specifications and reduces the equipment adjustment time and cost caused by changes in pipe specifications; the structural design is simple and ingenious, and without adding complex adjustment mechanisms, it achieves efficient support and stable transportation of pipes of different diameters, reduces the maintenance difficulty and manufacturing cost of the equipment, and has high practicality and economy.

[0065] Example 5: Please refer to Figure 9 and Figure 10 This embodiment is substantially the same as Embodiment 3, differing in that one end of the chain plate 11 is not provided with only one set of support members 21. To further optimize device performance, two sets of support members 21 are provided at each end of the chain plate 11, each set having two support members 21; one set of support members 21 is located between the other set of support members 21 and is lower in height than the other set of support members 21. This embodiment possesses the advantages of Embodiments 3 and 4.

[0066] Example 6: Please refer to Figures 11 to 15This embodiment is substantially the same as embodiment 2, except that the support member 21 is not fixedly connected to the mounting plate 22. To facilitate the transport of pipes of various diameters and improve the adaptability of the device, the support mechanism 2 further includes a connecting rod 25, a screw 26, a nut seat 27, and a worm gear reducer 28.

[0067] The support member 21 is hinged to the mounting plate 22 , and notches are provided on both sides of the mounting plate 22 for the support member 21 to move.

[0068] The worm gear reducer 28 is fixedly connected to the mounting plate 22. Specifically, the worm gear reducer 28 is fixedly connected to the chain plate 11 through the connecting plate, thereby maintaining a fixed connection with the mounting plate 22, or the worm gear reducer 28 is directly fixedly connected to the mounting plate 22 through the connecting plate.

[0069] The screw rod 26 is rotatably connected to the mounting plate 22 . Specifically, the screw rod 26 is rotatably connected to the mounting plate 22 via a bearing. The bearing is fixedly mounted on the mounting plate 22 or the chain plate 11 , and can realize the rotatable connection between the screw rod 26 and the mounting plate 22 .

[0070] The screw 26 is transmission-connected to the output end of the worm gear reducer 28 ; the nut seat 27 is threadedly connected to the screw 26 , one end of the connecting rod 25 is hinged to the end of the support member 21 away from the inclined surface 211 , and the other end of the connecting rod 25 is hinged to the nut seat 27 .

[0071] By driving the input shaft of the worm gear reducer 28 to rotate, the screw 26 rotates, and the nut seat 27 moves linearly on the screw 26. This drives the support member 21 to rotate about the hinge point through the connecting rod 25, thereby adjusting the angle of the support member 21. The structural characteristics of the worm gear reducer 28 also enable self-locking, ensuring that the angle of the support member 21 remains stable.

[0072] In this way, the angle of the support member 21 can be flexibly adjusted according to the pipe diameter and transportation requirements of different pipelines, further improving the adaptability of the device to different pipelines and enhancing the support and limiting effect on the pipelines. It should be noted that the two worm gear reducers 28 at both ends of the chain plate member 11 need to be adjusted in unison so that the adjustment angles of the chain plate members 11 at both ends correspond to each other.

[0073] Example 7: Please refer to Figure 16 and Figure 17 This embodiment is substantially the same as embodiment 3, except that the support member 21 is not fixedly connected to the mounting plate 22. To facilitate the transport of pipes of various diameters and improve the adaptability of the device, the support mechanism 2 further includes a connecting rod 25, a screw 26, a nut seat 27, and a worm gear reducer 28.

[0074] The support member 21 is hinged to the mounting plate 22 , and notches are provided on both sides of the mounting plate 22 for the support member 21 to move.

[0075] The worm gear reducer 28 is fixedly connected to the mounting plate 22 . Specifically, the worm gear reducer 28 is fixedly connected to the slider 23 via a connecting plate, thereby maintaining a fixed connection with the mounting plate 22 .

[0076] The screw rod 26 is rotationally connected to the mounting plate 22. Specifically, the screw rod 26 is rotationally connected to the slider 23 via a bearing. The bearing is fixedly mounted on the slider 23. Since the slider 23 is fixedly connected to the mounting plate 22, the screw rod 26 and the mounting plate 22 will maintain a rotational connection.

[0077] The screw 26 is transmission-connected to the output end of the worm gear reducer 28 ; the nut seat 27 is threadedly connected to the screw 26 , one end of the connecting rod 25 is hinged to the end of the support member 21 away from the inclined surface 211 , and the other end of the connecting rod 25 is hinged to the nut seat 27 .

[0078] By driving the input shaft of the worm gear reducer 28 to rotate, the screw 26 rotates, and the nut seat 27 moves linearly on the screw 26. This drives the support member 21 to rotate about the hinge point through the connecting rod 25, thereby adjusting the angle of the support member 21. The structural characteristics of the worm gear reducer 28 also enable self-locking, ensuring that the angle of the support member 21 remains stable.

[0079] In this way, the angle of the support member 21 can be flexibly adjusted according to the pipe diameter and transportation requirements of different pipelines, further improving the adaptability of the device to different pipelines and enhancing the support and limiting effect on the pipelines. It should be noted that the two worm gear reducers 28 at both ends of the chain plate member 11 need to be adjusted in unison so that the adjustment angles of the chain plate members 11 at both ends correspond to each other.

[0080] Example 8: Please refer to Figure 18 and Figure 19 On the basis of Example 6, in order to facilitate the automatic adjustment of the angle of the chain plate member 11, this embodiment also provides an automatic adjustment mechanism 3 on both sides of the chain plate conveying mechanism 1, and the automatic adjustment mechanism 3 includes a mounting frame 31, a power push rod 32, a push plate 33, and a rack 34. The mounting frame 31 is installed on the frame 12, and the power push rod 32 is installed on the mounting frame 31. The output end of the power push rod 32 is fixedly connected to the push plate 33, and the push plate 33 is fixedly connected to the rack 34; the support mechanism 2 also includes a gear 29, and the gear 29 is fixedly mounted on the input shaft of the worm gear reducer 28; the power push rod 32 uses an electric cylinder, an air cylinder or a hydraulic cylinder, and the rack 34 can be moved to the circular motion path of the gear 29 under the drive of the power push rod 32, and is used to engage with the gear 29.

[0081] The length of the rack 34 is less than the distance between the two gears 29. Thus, when the angle of the support member 21 needs to be adjusted, the power push rod 32 pushes the push plate 33, causing the rack 34 to move along the path of the gear 29 without contacting the gear 29 during the movement. When the rack 34 moves along the path of the gear 29, the gear 29 moves to a position close to the rack 34, and the lower end of the gear 29 meshes with the upper end of the rack 34. The rack 34 drives the gear 29 to rotate, thereby adjusting the angle of the support member 21 through components such as the worm gear reducer 28. The worm gear reducer 28 is self-locking, ensuring that when the support member 21 supports the pipeline, its angle will not change due to the pressure of the pipeline. When adjustment is no longer needed, the power push rod 32 is retracted, and the rack 34 leaves the path of the gear 29 to avoid affecting the normal operation of the chain conveyor mechanism 1.

[0082] The automatic adjustment mechanism 3 cooperates with the gear 29 to achieve automatic and precise adjustment of the angle of the support member 21, which greatly improves the efficiency compared with manual adjustment.

[0083] In this way, the angle adjustment of the support member 21 is automated, the intelligence level of the device and the convenience of operation are improved, and the angle of the support member 21 can be adjusted quickly and accurately according to the needs of different pipelines, thereby improving production efficiency. After the gear 29 completes a circular cycle with the chain plate conveyor mechanism 1, each gear 29 completes contact with the rack 34 once, completing a unified adjustment. The number of times the gear 29 is configured to circulate along the circular trajectory can be determined based on the angle that needs to be adjusted to the support plate. After the adjustment is completed, the gear 29 can also be manually rotated to fine-tune the angle of some supports 21 to ensure that the inclination angle of each support 21 is consistent.

[0084] The automatic adjustment mechanism 3 of this embodiment can also be applied to Example 7, but since the installation position of the mounting plate 22 of Example 7 on the chain plate member 11 is adjustable, in order to adapt to the various selectivities of the vertical reference plane of the cyclic motion path of the gear 29, when the power push rod 32 uses a cylinder or a hydraulic cylinder, a servo cylinder or a servo hydraulic cylinder that can output precise displacement should be selected. The rack 34 can move to multiple positions under the drive of the power push rod 32, so that the rack 34 can move to the cyclic motion path of the gear 29 and be used to engage with the gear 29.
