Description

Technical Field

[0001] The present invention relates to the technical field of pipeline conveying equipment, and particularly to a port-supported pipeline conveying device. Background Art

[0002] For pipelines such as centrifugally cast pipes, the outer surface is mostly treated with paint spraying to enhance the corrosion resistance of the pipeline. The painted pipeline is conveyed by a conveying device to the next working station and dried during the conveying process. Existing conveying devices generally support the bottom of the pipeline through support devices such as V-shaped grooves and conveyor belts, but the contact area between the outer wall of the pipe and the support device is large, which easily causes large-area damage and peeling of the uncured coating on the outer wall of the pipe, increasing the workload of subsequent manual paint repair and affecting the production efficiency of the overall pipeline product.

[0003] The patent with the publication number CN222845857U discloses a pipeline support conveying device, which includes a conveying device and a support adjusting device. The support adjusting device includes a telescopic column and a controller. By extending the telescopic column to support the outer wall of the pipe fitting, it is avoided that the pipe fitting directly contacts the "V"-shaped groove of the transmission chain plate, resulting in large-area damage to the coating, effectively reducing the contact area between the pipeline and the conveying device; when the coating on the outer wall of the pipe fitting is cured, the controller controls the telescopic column to retract. At this time, the top surface of the telescopic column is lower than the inclined surface of the "V"-shaped groove, and the pipe fitting is placed on the "V"-shaped groove of the transmission chain plate and transferred to the next process.

[0004] However, it has the following problems: 1. The telescopic column cannot limit the axial position of the pipeline, and there is a risk of axial movement of the pipeline; 2. The support point of the telescopic column on the pipeline is located on the circumferential surface of the pipeline, making it difficult to repair the paint, and the outer surface of the pipeline may still be unsightly after the paint repair. Summary of the Invention

[0005] 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 conveying and the axial position of the pipeline cannot be limited.

[0006] To achieve the above purpose, the present invention provides a port-supported pipeline conveying device, including a chain plate conveying mechanism and a support mechanism.

[0007] The chain plate conveying mechanism includes a plurality of chain plate members configured to move in a circular trajectory in a circulating manner.

[0008] The support mechanism includes support members arranged at both ends of the chain plate member. The upper end of the support member is provided with an inclined surface for contacting and cooperating with the pipeline port to support it. The inclined surfaces of the support members at both ends of the chain plate member face each other; when the pipeline is placed on the support member, it can receive a restraining force acting inward from the inclined surfaces of the support members at both ends of the chain plate member.

[0009] 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.

[0010] In an optional implementation, the mounting plate is fixedly mounted on the chain plate member.

[0011] 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 a plurality of positioning holes along its length direction; the supporting 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.

[0012] In an optional implementation, the support member is fixedly mounted on the mounting plate. Specifically, the support member can be firmly fixed on the mounting plate by welding, bolting, etc., to ensure that there is no 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.

[0013] In an optional implementation, two support members are provided at both ends of the chain plate. A total of four support members are provided, and the four support members jointly support the pipeline port to disperse the weight of the pipeline. At the same time, the two support members at each end cooperate with each other to further enhance the limiting effect of the pipeline, improve the supporting strength and stability of the pipeline, prevent the pipeline from falling or tilting due to insufficient supporting force during transportation, and better limit the lateral and longitudinal movement of the pipeline.

[0014] In an optional implementation, the support members at both ends of the chain plate member are arranged in two groups, and each group of support members has two support members; one group of support members is located between the other group of support members and has a lower height than the other group of support members.

[0015] 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 rotatably 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.

[0016] In an alternative implementation, automatic adjustment mechanisms are provided on both sides of the chain plate conveying mechanism. The automatic adjustment mechanism includes a mounting frame, a power push rod, a push plate, and a rack. The mounting frame is mounted on the machine frame, the power push rod is mounted 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 further includes a gear, which is fixedly installed on the input shaft of the worm and worm 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 for meshing and cooperating with the gear.

[0017] In an alternative implementation, the chain plate conveying mechanism includes a machine frame, a driving rotating shaft, a driven rotating shaft, a driving motor, a driving sprocket, a driven sprocket, a chain, a chain guide, and a fixing frame. The driving rotating shaft and the driven rotating shaft are both rotatably connected to the machine frame. The driving motor is fixedly connected to the machine frame, and the output end of the driving motor is in transmission connection with the driving rotating shaft. The driving sprocket is fixedly installed on the driving rotating shaft, the driven sprocket is fixedly installed on the driven rotating shaft, the driving sprocket and the driven sprocket are connected by a chain in transmission, the chain plate member is fixedly installed on the chain through the fixing frame, the chain guide is fixedly installed on the machine frame and is used for supporting the chain, and the chain is in contact and cooperation with the chain guide.

[0018] The beneficial effects of this technical solution are as follows: By providing support members with inclined surfaces at both ends of the chain plate member and the inclined surfaces facing each other, using the structure of the inclined surface, when the pipeline is under the action of gravity, an interaction force is generated with the inclined surface, forming an inward constraint on the pipeline, restricting the lateral movement of the pipeline, and being able to stably support and limit the pipeline, ensuring the stable progress of the conveying work; at the same time, the support member only contacts the pipeline port, which can avoid damaging the coating on the outer surface of the pipeline. Subsequently, only the port needs to be repainted, and the repainting operation is more convenient, and the effect of repainting the port is better and more beautiful, which can avoid the situation that the outer surface of the pipeline is not beautiful due to repainting.

Detailed implementation manners

[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0021] 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.

[0022] 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 .

[0023] 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 set to two, the driving sprocket 16 and the driven sprocket are transmission-connected through a chain 17, the chain 17 is a chain with accessories 17, the chain plate member 11 is fixedly mounted on the chain 17, the chain 17 guide member 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 member 18.

[0024] The driving motor 15 provides power to drive the driving shaft 13 to rotate, and the driving sprocket 16 on the driving shaft 13 drives the driven sprocket to rotate through the chain 17, so that the chain 17 circulates. The chain 17 guide 18 supports and guides the chain 17 to ensure that the chain 17 moves along a predetermined trajectory, and the chain plate member 11 installed on the chain 17 is also configured to circulate along a circular trajectory. The entire chain plate conveying mechanism 1 has a compact structure and stable transmission, and can reliably realize the circular cyclic motion of the chain plate member 11, providing stable power and motion trajectory for pipeline transportation.

[0025] 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. The specific fixed connection method can be achieved by welding. The method in which the support members 21 are directly fixed to the chain plate member 11 has a simple structure and low cost.

[0026] The upper end of the support member 21 is provided with an inclined surface 211 for contacting and cooperating with the pipe port to support it, and the inclined surfaces 211 of the support members 21 at both ends of the chain plate member 11 are arranged facing each other; when the pipe is placed on the support member 21, it can receive a constraining force acting inward from the inclined surfaces 211 of the support members 21 at both ends of the chain plate member 11. The inward constraining force specifically refers to the constraining force towards the central side of the region jointly surrounded by the support members 21 at both ends of the chain plate member 11.

[0027] The support members 21 at both ends of the chain plate member 11 can be set to n groups, and each group has two support members 21, where n is a positive integer.

[0028] In this embodiment, as Figure 1 shown, n is set to 1, that is, only one group of support members 21 is provided at one end of the chain plate member 11, and the total number of support members 21 on the chain plate member 11 is 4. The four support members 21 jointly support the pipe port to disperse the weight of the pipe. At the same time, the two support members 21 at each end cooperate with each other. Using the structure of the inclined surface 211, when the pipe is under the action of gravity, an interaction force is generated between the pipe and the inclined surface 211. Since the inclined surfaces 211 of the support members 21 at both ends face each other, an inward constraint on the pipe is formed, further enhancing the limiting effect on the pipe, improving the support strength and stability of the pipe, preventing the pipe from falling or tilting due to insufficient support force during transportation, and at the same time better restricting the lateral and longitudinal movement of the pipe. At the same time, the support member 21 only contacts the pipe port, which can avoid damaging the coating on the outer surface of the pipe.

[0029] However, the maximum distance between the two support members 21 at the same end is limited by the width of the chain plate member 11. If the width of the chain plate member 11 is set to be larger, the overall cost will increase. If the width of the chain plate member 11 is set to be smaller, the maximum distance between the two chain plate members 11 does not exceed the width of the chain plate member 11, and the maximum diameter of the pipe that can be adapted is smaller.

[0030] In other embodiments, when n is greater than 1, the distances between the two support members 21 in each group of support members 21 are different, so the pipe models adapted for support are also different. A group of support members 21 at an appropriate position can be selected according to the pipe diameter, so that a group of support members 21 at both ends of the chain plate member 11 support the pipe.

[0031] In the two support methods of the circumferential surface of the pipeline in the prior art and the port support in this embodiment, it is necessary to touch up the paint at the support points in the follow-up. However, the paint touch-up effect at 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 pipeline cylinder surface, and it is easy to leave debris and oil stains of the support on the edge of the arc surface, and the cleaning difficulty is high; the arc surface needs to be evenly painted along the trend of the curved surface, and it is easy to have uneven thickness and sag during manual operation; when mechanically spraying, the arc curvature may make it difficult to accurately match the spray gun angle, resulting in missed spraying or accumulation; after painting the arc surface, the painting angle and thickness of the painted area of the arc surface support point are different from those of the original coating, and color difference may occur. It is difficult for the boundary after painting to naturally transition with the original coating, resulting in a "patch" visual effect.

[0032] For the port support, the support points are located at the pipeline port. The port area is convenient for centralized cleaning, has less surface impurities, and the spraying or brushing operation is simpler; the paint touch-up points are located at the port, and the repair marks are not easily noticed by the naked eye.

[0033] To facilitate the installation of the chain 17 and keep it in a tensioned state, the driving rotating shaft 13 is rotationally connected to the frame 12 through a bearing. Two symmetrically arranged track bearing plates are installed on the frame 12. A bearing with a slider seat is slidably installed between the two track bearing plates. The driven rotating shaft 14 is rotationally connected to the bearing with a slider seat. A nut is fixedly installed on the frame 12, and an adjusting screw is threadedly installed on the nut. One end of the adjusting screw abuts against the bearing with a slider seat. By rotating the adjusting screw, under the guiding action of the track bearing plate, the adjusting screw pushes the bearing with a slider seat to move away from the nut, thereby increasing the distance between the driving rotating shaft 13 and the driven rotating shaft 14, and thus adjusting the tension degree of the chain 17.

[0034] Embodiment 2: Please refer to Figure 4 , this embodiment is substantially the same as Embodiment 1, and the difference lies in that the support member 21 and the chain plate member 11 are not directly connected, but indirectly connected. Specifically, the support mechanism 2 is further provided with a mounting plate 22. 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, so as to realize the indirect fixed connection between the support member 21 and the chain plate member 11.

[0035] The mounting plate 22 serves as an intermediate connecting member to connect the support member 21 and the chain plate member 11, enabling the support member 21 to be fixed on the chain plate member 11, thereby realizing the support for the pipeline. And the setting of the mounting plate 22 enables the two support members 21 at the same end of the chain plate member 11 to maintain a relatively large distance, without being limited by the width of the chain plate member 11.

[0036] Moreover, the mounting plate 22 is fixedly installed on the chain plate member 11. Specifically, a welding fixing method can be adopted, or riveting or bolt fixing methods can also be used to firmly install the mounting plate 22 on the chain plate member 11, so that the mounting plate 22 and the chain plate member 11 form a stable overall structure.

[0037] The position of the mounting plate 22 on the chain plate member 11 is fixed, thereby ensuring the stability of the position of the support member 21, making the support and limiting effects of the support mechanism 2 on the pipeline more reliable, and being applicable to scenarios with high requirements for the pipeline conveying position accuracy.

[0038] Embodiment 3: Please refer to Figure 5 and Figure 6 , this embodiment is substantially the same as Embodiment 2, and the difference lies in that the mounting plate 22 is not fixedly installed on the chain plate member 11. To facilitate the conveyance of pipelines of different lengths, the installation position of the mounting plate 22 on the chain plate member 11 is set to be adjustable. The chain plate member 11 has an inner cavity, the chain plate member 11 is specifically a rectangular pipe, 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 direction; 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, an internal thread hole is provided on the slider 23, and the slider 23 is fixedly connected to the chain plate member 11 through the fixing screw 24 passing through the positioning hole 112 and threadedly connected to the internal thread hole. The slider 23 is connected to the mounting plate 22 through a connecting bolt passing through the movable opening 111.

[0039] When the position of the mounting plate 22 needs to be adjusted, loosen the fixing screw 24, the slider 23 can slide along the length direction in the inner cavity of the chain plate member 11. After driving the mounting plate 22 to move to a suitable position, then tighten the fixing screw 24 to fix the slider 23 to the chain plate member 11 through the positioning hole 112. In this way, the position of the mounting plate 22 can be flexibly adjusted according to pipelines of different diameters, and then the position of the support member 21 can be adjusted to meet the support requirements of pipelines of different length specifications, greatly improving the applicability of the device.

[0040] Moreover, the support member 21 is fixedly installed on the mounting plate 22. Specifically, the support member 21 can be firmly fixed to the mounting plate 22 by welding, bolt connection and other methods, 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 conveyance.

[0041] Embodiment 4: Please refer to Figure 7 and Figure 8, This embodiment is substantially the same as Embodiment 2, except that only one set of support members 21 is not provided at one end of the link plate member 11. To further optimize the performance of the device, the support members 21 at both ends of the link plate member 11 are both provided with two sets, and the number of each set of support members 21 is two; 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.

[0042] The two sets of support members 21 with different heights form a stepped staggered layout. When transporting pipes with a smaller pipe diameter, the support members 21 with a lower height can be used to precisely support the pipe ports; when transporting pipes with a larger pipe diameter, the pipes with a larger pipe diameter will straddle the support members 21 with a lower height and be received by the support members 21 with a higher height. Through this way of combining high and low and setting them in a staggered manner, the adaptive support for pipes with different pipe diameters is realized.

[0043] By setting two sets of support members 21 with different heights and staggered distributions, it is possible to quickly adapt to pipes of various pipe diameters without adjusting the position or angle of the support members 21, significantly improving the versatility of the device for pipes of different specifications and reducing the equipment adjustment time and cost caused by changes in pipe specifications; this structural design is simple and ingenious. Without adding complex adjustment mechanisms, it realizes the efficient support and stable transportation of pipes with different pipe diameters, reduces the maintenance difficulty and manufacturing cost of the equipment, and has high practicality and economy.

[0044] Embodiment 5: Please refer to Figure 9 and Figure 10 , This embodiment is substantially the same as Embodiment 3, except that only one set of support members 21 is not provided at one end of the link plate member 11. To further optimize the performance of the device, the support members 21 at both ends of the link plate member 11 are both provided with two sets, and the number of each set of support members 21 is two; 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. It has the advantages possessed by the solutions of Embodiment 3 and Embodiment 4.

[0045] Embodiment 6: Please refer to Figures 11 to 15 , This embodiment is substantially the same as Embodiment 2, except that the support member 21 and the mounting plate 22 are not fixedly connected. To facilitate the transportation of various pipes with different pipe diameters and improve the adaptability of the device, the support mechanism 2 is further provided with a connecting rod 25, a screw rod 26, a nut seat 27, and a worm and worm gear reducer 28.

[0046] Among them, the support member 21 is hinged to the mounting plate 22, and notches for the support member 21 to move are provided on both sides of the mounting plate 22.

[0047] The worm and worm gear reducer 28 is fixedly connected to the mounting plate 22. Specifically, the worm and worm gear reducer 28 is fixedly connected to the link plate member 11 through a connecting plate, so as to be fixedly connected to the mounting plate 22, or the worm and worm gear reducer 28 is directly fixedly connected to the mounting plate 22 through a connecting plate.

[0048] 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 through a bearing, and the bearing is fixedly installed on the mounting plate 22 or the link plate member 11, both of which can realize the rotational connection between the screw rod 26 and the mounting plate 22.

[0049] The screw rod 26 is in transmission connection with the output end of the worm and worm gear reducer 28; the nut seat 27 is threadedly connected to the screw rod 26, and 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.

[0050] By driving the rotation of the input shaft of the worm and worm gear reducer 28, the screw rod 26 rotates, and the nut seat 27 moves linearly on the screw rod 26, driving the support member 21 to rotate around the hinge point through the connecting rod 25, so as to realize the adjustment of the angle of the support member 21. The self-locking characteristic of the structure of the worm and worm gear reducer 28 can also realize self-locking, so that the angle of the support member 21 remains stable.

[0051] In this way, the angle of the support member 21 can be flexibly adjusted according to the pipe diameters and conveying requirements of different pipes, further improving the adaptability of the device to different pipes, and at the same time enhancing the support and limiting effects on the pipes. It should be noted that the two worm and worm gear reducers 28 at both ends of the link plate member 11 need to be adjusted consistently, so that the adjustment angles of the link plate members 11 at both ends correspond consistently.

[0052] Embodiment 7: Please refer to Figure 16 and Figure 17 , this embodiment is substantially the same as Embodiment 3, the difference being that the support member 21 is not fixedly connected to the mounting plate 22. To facilitate the conveying of pipes with various different diameters and improve the adaptability of the device, the support mechanism 2 is provided with a connecting rod 25, a screw rod 26, a nut seat 27, and a worm and worm gear reducer 28.

[0053] Among them, the support member 21 is hinged to the mounting plate 22, and notches for the movement of the support member 21 are provided on both sides of the mounting plate 22.

[0054] The worm and worm gear reducer 28 is fixedly connected to the mounting plate 22. Specifically, the worm and worm gear reducer 28 is fixedly connected to the slider 23 through a connecting plate, so as to be fixedly connected to the mounting plate 22.

[0055] The screw rod 26 is rotatably connected to the mounting plate 22. Specifically, the screw rod 26 is rotatably connected to the slider 23 through a bearing, and the bearing is fixedly installed 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 rotatable connection.

[0056] The screw rod 26 is drivingly connected to the output end of the worm and worm gear reducer 28; the nut seat 27 is threadedly connected to the screw rod 26. One end of the connecting rod 25 is hinged to one 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.

[0057] By driving the rotation of the input shaft of the worm and worm gear reducer 28, the screw rod 26 rotates, and the nut seat 27 moves linearly on the screw rod 26. The connecting rod 25 drives the support member 21 to rotate around the hinge point, thereby realizing the adjustment of the angle of the support member 21. The self-locking characteristic of the structure of the worm and worm gear reducer 28 can also achieve self-locking, so that the angle of the support member 21 remains stable.

[0058] In this way, the angle of the support member 21 can be flexibly adjusted according to the pipe diameters and conveying requirements of different pipes, further improving the adaptability of the device to different pipes, and at the same time enhancing the support and limiting effects on the pipes. It should be noted that the two worm and worm gear reducers 28 at both ends of the chain plate member 11 need to be adjusted consistently, so that the adjustment angles of the chain plate members 11 at both ends correspond consistently.

[0059] Embodiment 8: Please refer to Figure 18 and Figure 19 , on the basis of Embodiment 6, in order to facilitate the automatic adjustment of the angle of the chain plate member 11, an automatic adjustment mechanism 3 is further provided on both sides of the chain plate conveying mechanism 1 in this embodiment. 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 machine frame 12, 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 further includes a gear 29, and the gear 29 is fixedly installed on the input shaft of the worm and worm gear reducer 28; the power push rod 32 is selected from an electric cylinder, a pneumatic cylinder or a hydraulic cylinder. 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 for meshing with the gear 29.

[0060] The length of the rack 34 is less than the distance between the two gears 29. In this way, when the angle of the support member 21 needs to be adjusted, the power push rod 32 pushes the push plate 33 to move the rack 34 onto the movement path of the gear 29 without contacting the gear 29 during the movement process. After the rack 34 moves onto the movement 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, and then the angle of the support member 21 is adjusted through components such as the worm and worm gear reducer 28. Moreover, the worm and worm gear reducer 28 can achieve self-locking to ensure that the angle of the support member 21 will not change due to the pressure of the pipeline when supporting the pipeline. When adjustment is not required, the power push rod 32 retracts, and the rack 34 leaves the movement path of the gear 29 to avoid affecting the normal operation of the chain plate conveying mechanism 1.

[0061] This automatic adjustment mechanism 3 realizes the automatic and precise adjustment of the angle of the support member 21 through cooperation with the gear 29. Compared with manual adjustment, the efficiency is greatly improved.

[0062] In this way, the automatic adjustment of the angle of the support member 21 is realized, the intelligent level of the device and the convenience of operation are improved, the angle of the support member 21 can be quickly and accurately adjusted according to the needs of different pipelines, and the production efficiency is improved. After each gear 29 completes one circular cycle movement with the chain plate conveying mechanism 1, each gear 29 contacts the rack 34 once to complete a unified adjustment. The number of times the gear 29 is configured to move in a circular trajectory can be determined according to the angle that needs to be adjusted for the support plate. After the adjustment is completed, the gear 29 can also be manually rotated to finely adjust the angles of some support members 21 to ensure that the inclination angles of all support members 21 are consistent.

[0063] The automatic adjustment mechanism 3 of this embodiment can also be applied to Embodiment 7. However, since the installation position of the mounting plate 22 in the chain plate member 11 in Embodiment 7 is adjustable, in order to adapt to various selectable vertical reference planes of the circular movement path of the gear 29, when the power push rod 32 is selected as 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, which is convenient for the rack 34 to move to the circular movement path of the gear 29 and be used for meshing and cooperation with the gear 29.
