[0002] LNG gas cylinders are usually divided into inner and outer cylinders. During the production process, the welded inner cylinder needs to be hoisted into the outer cylinder before welding the outer cylinder. In actual operation, the outer cylinder needs to be flipped 90° to a vertical state. At present, manual flipping is mainly used for flipping the outer cylinder of LNG gas cylinders. Due to the large size and weight of LNG gas cylinders, the workpiece needs to be moved and hoisted during the flipping process. Manual operations are difficult and complicated, and bumps and other problems may occur. Its reliability and safety cannot be guaranteed, and the production efficiency is low, and there are certain safety risks. Summary of the invention

[0003] One object of the present invention is to solve the deficiencies in the prior art and to provide a turning device and a turning control system which can realize mechanical turning of a tank body and are relatively easy to operate.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A turning device, comprising:

[0006] The base is provided with a frame and a rotating shaft rotatably arranged on the frame,

[0007] A conveying track, used for conveying the tank body and supporting the side wall of the tank body, wherein the conveying track is arranged above the base;

[0009] A driving device, wherein a driving end of the driving device is drivingly connected to the overturning frame, and is used to drive the overturning frame and the conveying track to rotate around the rotating shaft.

[0010] In one embodiment, a sensor is provided on the bottom tray. When the can body is conveyed to the bottom tray, the can body contacts the bottom tray and the sensor senses an arrival signal of the can body. The sensor is electrically connected to the driving device by a signal. The driving device drives the conveying track and the flip frame to rotate according to the arrival signal.

[0011] In one embodiment, the conveying track includes a frame and a transmission roller, the frame extends along the conveying direction, the transmission roller is arranged perpendicular to the frame, and conical rollers adapted to the outer side wall of the tank body are provided on both sides of the transmission roller.

[0012] In one embodiment, the conveying track further includes a plurality of side-blocking rollers, which are installed on both sides of the frame, and the side-blocking rollers and the driving rollers are distributed along the circumference of the tank body.

[0013] In one embodiment, the support frame includes a first bracket extending along the extending direction of the conveying track and a second bracket extending perpendicular to the extending direction of the conveying track, and the bottom tray is mounted on the second bracket.

[0014] In one embodiment, the first bracket includes a first linear slide rail, the first linear slide rail extends along the first bracket, and the second bracket moves along the first linear slide rail.

[0019] It can be seen from the above technical solution that the present invention has at least the following advantages and positive effects:

[0020] In the above-mentioned turning device, the base is used to support the conveying track and the turning frame. The conveying track transports the gas cylinder to the turning frame, and the driving device drives the turning frame to turn over, thereby realizing the turning of the tank body. The turning operation is relatively simple and easy to implement, avoiding the use of manpower to turn over the tank body, and has high safety.

[0021] When the diameters and lengths of the tanks are different, the position of the bottom bracket is automatically adjusted according to the diameter of the tanks, and the position of the bottom bracket is adapted to the automatic docking and conveying of tanks of different diameters. At the same time, the center of the bottom bracket is ensured to overlap with the center of the tank, and the stability of the support switching from the conveying track to the bottom bracket is ensured during the tank flipping process, thereby ensuring the stability of the bottom bracket support. In addition, considering that the lengths of the tanks are different, the height of the upper surface of the tanks after flipping is inconsistent, and the corresponding manual operation height is different. The second bracket adjusts its position on the first bracket to adapt to tanks of different lengths, so that the manual operation height of the tanks after flipping is consistent.

[0044] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially used for illustration purposes rather than for limiting the present invention.

[0045] In the description of the present application, it should be understood that in the embodiments shown in the drawings, the indications of directions or positional relationships (such as up, down, left, right, front and back, etc.) are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the devices or elements referred to must have a specific orientation, be constructed and operate in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, the indications of these directions also change accordingly.

[0046] See also Figure 1 The flipping device 10 of this embodiment is specifically used to flip the outer cylinder of the gas cylinder or tank body by 90 degrees and then fit it with the inner cylinder body. The flipped workpiece here is not limited to tank bodies, LNG gas cylinders, Dewar flasks and other similar structural products, and the processing operation is not limited to the above flipping angles. According to specific processing requirements, the tank body, gas cylinder and other processing workpieces can be flipped accordingly.

[0047] See also Figure 1 and Figure 2 The present embodiment provides a turning device 10, which includes a base 11, a conveying track 12, a turning frame 13 and a driving device 14. The base 11 is used to support the conveying track 12 and the turning frame 13. The conveying track 12 transports the gas cylinder to the turning frame 13, and the driving device 14 drives the turning frame 13 to turn over, thereby realizing the turning over of the tank body 2. The turning operation is relatively simple and easy to implement, avoiding the use of manpower to turn over the tank body 2, and the safety is relatively high.

[0048] See also Figure 3 The base 11 is provided with a frame 111 and a rotary shaft 112 rotatably arranged on the frame. The frame 111 is used to support the conveying track 12. Specifically in this embodiment, the frame 111 is formed by welding and fixing steel materials to each other. The frame 111 can be placed on the ground A. A fixing seat 113 is provided at the bottom of the frame 111, and the fixing seat 113 can increase the contact area between the frame 111 and the ground A, and enhance the support stability of the frame 111.

[0049] The rotating shaft 112 can be rotatably mounted on the frame 111. In addition, the rotating shaft 112 is disposed at one end of the base 11. The rotating shaft 112 is fixed by bearing seats fixed on both sides of the frame 111. For the convenience of description, it is now stipulated that the axial direction of the rotating shaft 112 is the transverse direction, and the direction perpendicular to the rotating shaft 112 is the longitudinal direction.

[0050] See also Figure 4 and Figure 5The conveying track 12 is used to convey the tank body 2 and provide support for the tank body 2 during the overturning process. The conveying track 12 supports the side wall of the tank body 2 and is arranged above the base 11. The conveying track 12 includes a frame 121 and a transmission roller 122. The frame 121 extends along the conveying direction, and the transmission roller 122 is arranged perpendicular to the extension direction of the frame 121. During the loading and unloading process, the transmission roller 122 can reduce the friction force on the tank body 2. The transmission roller 122 adopts a double sprocket design, and the sprockets are connected one by one through a chain to ensure that the transmission roller 122 can conduct stably and at a uniform speed.

[0051] Conical rollers 123 adapted to the outer wall of the tank body 2 are provided on both sides of the transmission roller 122. The design of the conical roller 123 can be better compatible with tank bodies 2 of different diameters. The conical roller 123 has a good automatic adaptation function. The contact surface between the conical roller 123 and the tank body 2 is an oblique line. During the conveying process, the center line of the tank body 2 is ensured to be on the center surface of the transmission roller 122 of the conveying track 12, and the conveying process is more stable. In addition, the contact points between the tank bodies 2 of different diameters and the conical roller 123 are different, and the conical roller 123 wears more evenly during use, extending the service life.

[0052] The conveying track 12 further includes a plurality of side rollers 124, which are mounted on both sides of the frame 121. The side rollers 124 and the driving rollers 122 are distributed along the circumference of the tank body 2. Specifically, side supports 125 are further provided on both sides of the frame 121, and the side rollers 124 are fixed on the side supports 125. In the circumference of the tank body 2, the side rollers 124 increase the support range of the conveying track 12 and the tank body 2, which can prevent the large-sized tank body 2 from tilting or falling sideways, and improve the stability of the tank body 2 on the conveying track 12.

[0053] See also Figure 5 The turning frame 13 includes a supporting frame 131, a bottom bracket 132 and a fixing plate 133 arranged on the supporting frame 131. The fixing plate 133 is arranged on the bottom bracket 132. The supporting frame 131 is arranged above the base 11 and is rotatably connected to the rotating shaft 112. The conveying track 12 is fixedly arranged on the supporting frame 131. The bottom bracket 132 is used to dock with the end of the tank body 2 and support the tank body 2 after turning over.

[0054] The driving end of the driving device 14 is drivingly connected to the turning frame 13, and is used to drive the turning frame 13 and the conveying track 12 to rotate around the rotating shaft 112. One end of the driving device 14 is a fixed end 141, and the fixed end 141 is hinged to the cylinder mounting seat 142, and the cylinder mounting seat 142 is fixed to the ground A by expansion bolts. The other end of the driving device 14 is a driving end 143, and the driving end 143 is rotatably connected to the support frame 131 to provide turning power.

[0055] The connection between the driving end 143 and the support frame 131 is located at the end of the support frame 131 away from the bottom bracket 132. The extension of the driving device 14 can drive the support frame 131 to rotate counterclockwise to a vertical state. On the contrary, the contraction of the driving device 14 can drive the support frame 131 to rotate clockwise to reset. The driving device 14 can be a telescopic cylinder, a hydraulic cylinder, etc. The driving device 14 has a simple structure, stable movement, and is stable and reliable.

[0056] In other embodiments, the connection between the driving end 143 of the driving device 14 and the support frame 131 can also be located at one end of the support frame 131 close to the base 132. Then the driving device 14 can also drive the support frame 131 to rotate around the rotating shaft 112 through telescopic movement. That is, when the driving device 14 contracts, it drives the support frame 131 to rotate counterclockwise to a vertical state; conversely, the extension of the driving device 14 can drive the support frame 131 to rotate clockwise to reset. Here, the setting position of the driving device 14 is not specifically limited, and the way in which the telescopic movement of the driving device 14 drives the support frame 131 to rotate is not limited.

[0057] See also Figure 6 and Figure 7 The support frame 131 includes two longitudinal beams 134 extending in the longitudinal direction. The two longitudinal beams 134 are supported and arranged above the frame body 111. The two longitudinal beams 134 of the support frame 131 are rotatably connected to the two ends of the rotating shaft 112. The frame 121 of the conveying track 12 is fixed on the two longitudinal beams 134. The support frame 131 can rotate around the rotating shaft 112, so that the flip frame 13 and the conveying track 12 rotate as a whole with the rotating shaft 112 as the axis. When the flip angle of the flip frame 13 is 90 degrees, the flip frame 13 can flip from a horizontal state to a vertical state.

[0058] At the same time, the turning device 10 is also provided with a limit seat 15. The limit seat 15 is arranged in the foundation pit on the ground A. The limit seat 15 is correspondingly arranged below the turning frame 13. A buffer block 151 is fixed on the limit seat 15. When the turning frame 13 turns 90° to a vertical state, the turning frame 13 contacts the buffer block 151 to ensure the accuracy and stability of the turning process. There can be one or more limit seats 15, as long as they can stably support the turning frame 13 in the vertical state.

[0059] Specifically in this embodiment, the support frame 131 includes a first bracket 135 extending along the extension direction of the conveying track 12 and a second bracket 136 extending perpendicular to the extension direction of the conveying track 12. The first bracket 135 includes a first linear slide 1351. The first linear slide 1351 extends along the first bracket 135, and the second bracket 136 moves along the first linear slide 1351. The flip frame 13 also includes a first driving assembly provided on the first bracket 135, and the first driving assembly 1350 drives the second bracket 136 to move along the first linear slide 1351.

[0060] The first drive assembly 1350 may include a first motor 1352 and a first screw rod 1353. The first screw rod 1353 is fixed to the first bracket 135 through a screw nut. The first motor 1352 drives the first screw rod 1353 to rotate, thereby realizing automatic adjustment of the second bracket 136 on the first linear slide rail 1351. In other embodiments, the first drive assembly second bracket 136 may also be manually adjusted according to the worker's working conditions. The first screw rod 1353 may be a trapezoidal screw rod.

[0061] The bottom support 132 is mounted on the second bracket 136. The bottom support 132 is used to support the end of the tank body 2. The bottom support 132 is in a vertical state. Specifically in this embodiment, the fixing plate 133 is provided with a groove, and the end of the head of the tank body 2 can be embedded in the fixing plate 133, so that the tank body 2 can be supported more stably.

[0062] A sensor 137 is provided on the bottom support 132. When the tank body 2 is transported to the bottom support 132, the tank body 2 contacts the bottom support 132, and the sensor 137 senses the arrival signal of the tank body 2. The sensor 137 is electrically connected to the driving device 14, and the driving device 14 drives the conveying track 12 and the turning frame 13 to rotate according to the arrival signal. The sensor 137 can be an acoustic and optical sensor 137, a pressure sensor 137, etc. As long as it can sense that the tank body 2 is transported to the right position, a control signal is sent to the driving device 14, so that the driving device 14 drives the turning frame 13 to turn over. Therefore, the turning device 10 can automatically trigger the turning operation of the turning frame 13 by the driving device 14, and the operation is convenient.

[0063] The second bracket 136 includes a second linear slide 1361. The second linear slide 1361 extends along the second bracket 136, and the bottom bracket 132 moves along the second linear slide 1361. The flip frame 13 also includes a second drive assembly 1360 disposed on the second bracket 136, and the second drive assembly 1360 drives the bottom bracket 132 to move along the second linear slide 1361. The second drive assembly 1360 may include a second motor 1362 and a second screw rod 1363. The second motor 1362 may be a servo motor. The second screw rod 1363 may be a trapezoidal screw rod.

[0064] The bottom bracket 132 is connected to the second bracket 136 through the second linear slide rail 1361, and the servo motor drives the second screw rod 1363 to rotate through the pulley, so that the bottom bracket 132 can be adjusted in the extension direction of the second bracket 136. When the flip frame 13 flips the tank body 2 to a vertical state, the second bracket 136 extends in the horizontal direction, that is, the position of the bottom bracket 132 in the horizontal direction is adjusted, and the tank body 2 can rotate on the bottom bracket 132 with the fixed plate 133. At the same time, four groups of swivel support wheels 138 are provided on the bottom bracket 132. The four groups of swivel support wheels 138 are symmetrically arranged at the center of the bottom of the fixed plate 133. The fixed plate 133 is supported by four groups of swivel support wheels 138, and the swivel support wheels 138 can prevent the fixed plate 133 from rotating relative to the tank body 2 when the position is adjusted, which affects the stable support relationship between the fixed plate 133 and the tank body 2.

[0065] See also Figure 8 Since the volume and specifications of the tank body 2 are different, the diameter and length of the tank body 2 are different. Therefore, the position of the bottom bracket 132 is automatically adjusted according to the diameter of the tank body 2, and the position of the bottom bracket 132 can adapt to the automatic docking and transportation of tank bodies 2 of different diameters. At the same time, it is ensured that the center of the bottom bracket 132 overlaps with the center of the tank body 2, and the stability of the support switching from the conveying track 12 to the bottom bracket 132 during the overturning of the tank body 2 is ensured, and the stability of the support of the bottom bracket 132 is ensured. In addition, considering that the length of the tank body 2 is different, the height of the upper surface of the tank body 2 after the overturning is inconsistent, and the corresponding manual operation height is different. The second bracket 136 adjusts its position on the first bracket 135 to adapt to tank bodies 2 of different lengths, so that the manual operation height of the tank body 2 after the overturning is consistent. And the deviation value can be set in advance in the system according to the actual workers.

[0066] Please refer again Figure 1 A telescopic platform 16 is provided outside the pit of the turning device 10, and the operator can stand on the telescopic platform 16. A plurality of telescopic platforms 16 can be provided, and they are respectively located on different sides of the tank body 2, so that the operator can operate the tank body 2 from different directions. The telescopic platform 16 can adjust the standing height of the operator to ensure that the outside of the tank body 2 with different diameters is at the same distance from the operator, which is convenient for subsequent operations.

[0067] In other embodiments, the first motor 1352 and the second motor 1362 may also be added or replaced with a manual control device according to actual use conditions, and manual control adjustment may be performed through the manual control device, wherein the manual control device includes but is not limited to a manual control device such as a hand wheel.

[0068] The first bracket 135 and the second bracket 136 can meet the flipping operation of tanks 2 of different diameters and lengths through the dynamic adjustment of the first driving assembly 1350 and the second driving assembly 1360. Therefore, the flipping device 10 has high versatility and can meet the flipping use requirements of most types and models of tanks 2.

[0069] If the diameter deviation of the tank body 2 is too large, the fixing plate 133 on the bottom bracket 132 can also adopt a quick-release structure, and the model of the fixing plate 133 can be replaced according to the different ranges of cylinders to ensure the stability of the fixing plate 133 supporting the tank body 2 to ensure its safety.

[0070] See also Fig. 9 and Fig.10 In addition, this embodiment further provides a turnover control system 1. The turnover control system 1 includes a turnover device 10 and a production line control system 20. The turnover device 10 is electrically connected to the production line control system 20. The production line control system 20 may include an upper computer system 21 and a lower computer system 22. The upper computer system 21 is used to transport the tank body 2 to the upper position, and the upper computer system 21 stores or measures the size information of the transported tank body 2. The lower computer system 22 is used to transport the tank body 2 to the lower position.

[0071] Specifically, the turning device 10 includes a controller 19. The controller 19 is electrically connected to the host computer system 21. The controller 19 can receive the size information of the tank body 2 from the host computer system 21.

[0072] The controller 19 is connected to the sensor 137, the driving device 14 of the conveying track 12, the first driving assembly 1350 and the second driving assembly 1360 by electrical signals. The controller 19 generates the position information of the second bracket 136 and the position information of the bottom bracket 132 according to the size information of the tank body 2. The controller 19 automatically adjusts the position of the second bracket 136 on the first bracket 135 and the position of the bottom bracket 132 on the second bracket 136 according to the position information of the second bracket 136 and the position information of the bottom bracket 132, so as to realize the automatic adjustment, automatic docking, operation and transportation of the second bracket 136 and the bottom bracket 132, meet the automatic production docking requirements of the production line, and realize the coordinated operation of the entire production line.

[0073] Now, in combination with the specific operation process of the flip device 10 and the flip control system 1, the flip device 10 and the flip control system 1 are further described:

[0074] First, the tank body 2 is uploaded to the upper computer system 21, and the upper computer system 21 sends the size information of the tank body 2 to the controller 19 of the flipping device 10. The controller 19 receives the size information and controls the adjustment of the positions of the second bracket 136 and the bottom bracket 132.

[0075] The tank body 2 enters the conveying track 12 and is conveyed forward until the tank body 2 contacts the base 132. The sensor 137 installed on the base 132 detects that the tank body 2 is in place and sends a control signal indicating that the tank body 2 is in place to the controller 19. The controller 19 controls the conveying track 12 to stop conveying.

[0076] After the conveying track 12 stops conveying, the controller 19 controls the driving device 14 to extend and push the flip frame 13 to flip to a vertical state. Then, the central axis of the flipped tank body 2 coincides with the central axis of the bottom support 132, and the operating height of the tank body 2 is just at the manual operation height of the telescopic step 16.

[0077] After the worker completes the work on the telescopic step 16, the driving device 14 retracts, pulling the turning frame 13 to turn back to the horizontal state, and the tank body 2 is then transported by the conveying track 12 to dock with the external line body.

[0078] The flip control system 1 of this embodiment can link the flip device 10, the upper computer system 21 and the lower computer system 22 to realize automated and digital production, including but not limited to automatic identification of process routes based on single-process or multi-process systems of production lines, and automatic control of materials to transport corresponding products to workstations that need to be processed. The system can automatically identify and issue product processing parameters, automatically detect the correctness of the pairing and record the results of the pairing, and realize key component binding and full-process traceability of materials-products-materials during the production process.

[0079] Moreover, during the production line circulation process, the flip control system 1 sends the corresponding tank body 2 to the workstation that needs to be processed according to the configured process route, and can automatically control the conveying time, beat, stop time, material correspondence and other related automation controls of the tank body 2, and automatically identify and send product processing parameters.

[0080] When the can 2 flows to the corresponding workstation system, the turnover control system 1 automatically sends the corresponding processing parameters to the corresponding operating equipment, and the operating equipment binds the key components according to the actual situation to achieve the subsequent material-product reverse traceability. At the same time, the turnover control system 1 can automatically detect the correctness of the grouping and record the grouping results.

[0081] The above embodiments are merely exemplary descriptions of the structures. The structures in the embodiments are not fixed combination structures. In the absence of structural conflicts, the structures in multiple embodiments can be used in any combination.

[0082] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the present invention can be embodied in a variety of forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims, so all changes and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
