Description

Technical Field

[0001] This application relates to the technical field of ocean transportation, and particularly to a transportation and storage device for large-sized structural components used in ship engineering. Background Art

[0002] With the increasingly significant trend of the continuous increase in the volume and weight of items in global maritime transportation, the demand for large-sized structural components in the ocean transportation field continues to rise. To effectively address this challenge, the transportation industry is actively engaged in the research and development and application of new technologies and new equipment, aiming to improve the dual standards of transportation efficiency and cargo safety.

[0003] Among many shipping goods, circular pipe fittings such as oil and gas pipelines account for a considerable proportion. However, the current transportation methods for such circular pipe fittings mostly rely on traditional stacking and fixing methods, that is, four vertically arranged stop bars are installed on the cabin floor, and the round pipes are stacked between them. Although this method realizes the preliminary fixation of the pipe fittings to a certain extent, in the face of the complex and changeable marine environment, the relative sway of the hull often results in insufficient fastening force between the directly stacked pipe fittings, thereby increasing the risk of part slipping.

[0004] In addition, the hollow structure characteristics of circular pipe fittings also bring new problems during transportation. When the pipe fittings are stacked, their bottoms will bear greater pressure. Especially for those pipe fittings with thinner wall thicknesses, long-term concentrated pressure is extremely likely to cause bottom deformation or even breakage, seriously reducing the overall quality and safety of pipe fitting transportation. Summary of the Invention

[0005] This application proposes a transportation and storage device for large-sized structural components used in ship engineering, which has the advantage of fixing pipe fittings one by one to solve the problem that pipe fittings are prone to slipping due to stacking in the above-mentioned background art.

[0006] To achieve the above object, this application adopts the following technical solution: A transportation and storage device for large-sized structural components used in ship engineering, comprising: a storage support frame, with a height adjustment frame installed on the side and a support base for limiting pipe fittings installed at the inner bottom; a support stop arm, movably installed on the side of the height adjustment frame; a transmission rod, installed on the side of the height adjustment frame, and the transmission rod is firmly connected to the support stop arm, and a rubber wheel is coaxially and firmly fixed at one end of the transmission rod; an adjustment arm frame, installed on the height adjustment frame, and the bottom of the adjustment arm frame is closely attached to the outer side of the rubber wheel, and an adjustment tension spring is connected between the side of the adjustment arm frame and the height adjustment frame; a magnetic block, fixed at the end of the adjustment arm frame, and two symmetric magnetic blocks at the same horizontal height repel each other magnetically.

[0007] Further, a locking gear is coaxially and firmly fixed at the end of the transmission rod, and a locking tooth row is firmly fixed at the bottom of the adjustment arm frame.

[0008] Furthermore, a reversing wheel is movably installed on the side of the storage support frame, and a connecting ring is transmission-connected to the outer side of the reversing wheel, an adjusting motor coaxially fastened to the reversing wheel is fastened to the side of the storage support frame, a fixed base is fastened to the connecting ring, and a pressure roller is installed on the fixed base, a return push seat is fastened to the top of the adjusting arm frame, and an in-position indicator groove is opened on the top of the adjusting arm frame.

[0009] Furthermore, a guide slide is fastened to the end of the height adjustment frame, and a limiting tooth head is movably installed on the guide slide. The back of the limiting tooth head is fastened to a limiting intermediate rod, and one end of the limiting intermediate rod is located at the top of the adjustment arm frame. A limiting block is fastened to the top of the adjustment arm frame, and a limiting tooth row is movably installed in the storage support frame, and a directional component is arranged between the limiting tooth row and the inner side of the storage support frame. A screw rod is movably installed at the bottom of the storage support frame, and the screw rod and the limiting tooth row are threadedly connected.

[0010] Furthermore, a reset servo motor is fastened to the side of the storage support frame, and the rotating shaft and the screw of the reset servo motor are coaxially fastened.

[0011] Furthermore, a control handle is fastened to one end of the screw rod, and a limit indicating frame is fixedly installed on the side of the storage support frame.

[0012] Furthermore, a synchronous connecting frame is fastened to the bottom of the limiting gear row.

[0013] Furthermore, an anti-collision cylinder is fastened to the top of the height adjustment frame.

[0014] Furthermore, one end of the pressure roller is movably installed in the fixed base through a slider, a top spring is connected between the slider and the fixed base, and a stop switch is fixedly installed on the inner side of the fixed base. When the stop switch is pressed, the adjustment motor stops working.

[0015] The present invention has the following beneficial effects:

[0016] The present application provides a transportation and storage device for large-sized structural parts for ship engineering, which symmetrically and cleverly arranges multiple groups of up and down deflected support arms on the storage support frame. When the pipes are placed on the device, the support arms will form a unique X-shaped cross layout. This layout not only enhances the overall rigidity of the support structure, but also enables the upper and lower parts of the support arms to simultaneously and tightly clamp the pipes, achieving an all-round, no-dead-angle fastening effect. This design not only effectively prevents the shaking and slipping of pipes during transportation, but also significantly improves the safety and stability of stacked transportation, allowing more pipes to be safely and orderly stacked together, greatly improving transportation efficiency and space utilization.

[0017] In addition, the device also makes full use of the support retaining arm as a separating and fixing device between pipe fittings, ensuring that each pipe fitting can be clamped independently and firmly. This strategy of fixing one by one not only avoids mutual extrusion and collision damage between pipe fittings, but also further improves the operation efficiency and flexibility.

Detailed implementation mode

[0031] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application. Embodiment 1

[0032] Please refer to Figure 1 It can be seen that the storage support frame 1 is composed of four vertically arranged columns, and the bottoms of the four columns are firmly connected by steel plates. The bottom of the storage support frame 1 is firmly fixed on the cargo ship by bolts. A height adjustment frame 2 is movably installed on the side of the storage support frame 1. The number of height adjustment frames 2 is multiple, and the two sides of the storage support frame 1 are provided with height adjustment frames 2 with corresponding numbers.

[0033] Combined with Figure 1 , Figure 2 and Figure 4 It can be seen that a support base 7 is installed at the inner bottom of the storage support frame 1, and the four corners of the support base 7 are respectively fixed on the storage support frame 1. Multiple groups of right-angled triangle frames are arranged on the surface of the support base 7, thereby forming a "V" groove capable of limiting the round pipe. When the pipe fitting 4 is placed on the inclined surface of the right-angled triangle frame, the pipe fitting 4 can be supported and limited. In order to enable stacking and fixing between multiple pipe fittings 4, combined with Figure 5 It can be clearly seen that a support retaining arm 3 is movably installed on the side of the height adjustment frame 2. The support retaining arm 3 is composed of an "I"-shaped steel, and an anti-slip pad is installed on the side of the support retaining arm 3 to realize the support and fixation of the pipe fitting 4. As Figure 2As shown, after the pipe fitting 4 is placed on the support base 7, the support retaining arms 3 are deflected so that the two support retaining arms 3 are arranged in an "X" shape. Among them, the lower part of the support retaining arm 3 can clamp and fix the pipe fitting 4, and the upper part of the support retaining arm 3 forms a "V"-shaped fixing notch, so that the pipe fitting 4 can be stacked on the support retaining arm 3, and finally the stacking storage between multiple pipe fittings 4 is completed.

[0034] During the actual stacking process, due to the influence of its own gravity, the support retaining arm 3 always has a tendency to deflect downward, which causes the support retaining arm 3 to be unable to be pressed in a timely manner when the pipe fitting 4 is placed. To solve such problems, combined with Figure 5 and Figure 6 It can be seen that a transmission rod 15 is movably installed on the side of the height adjustment frame 2, and the transmission rod 15 is fixedly connected to the support retaining arm 3. The central axis of the transmission rod 15 coincides with the rotation center axis of the support retaining arm 3. When the transmission rod 15 rotates, the support retaining arm 3 will deflect up and down synchronously. One end of the transmission rod 15 is coaxially fixedly connected with a rubber wheel 150. Correspondingly, an adjustment arm frame 9 perpendicular to the transmission rod 15 is movably installed in the height adjustment frame 2. The bottom of the adjustment arm frame 9 contacts the outer side of the rubber wheel 150. When the adjustment arm frame 9 moves along the height adjustment frame 2, the friction force between the adjustment arm frame 9 and the rubber wheel 150 can force the transmission rod 15 to drive the support retaining arm 3 to deflect. For the motion control of the adjustment arm frame 9, from Figure 6 and Figure 7 It can be seen that an adjustment tension spring 12 is connected between the side of the adjustment arm frame 9 and the height adjustment frame 2. Under the action of the tension of the adjustment tension spring 12, the adjustment arm frame 9 is forced to always have a tendency to move towards the rubber wheel 150. Combined with the adjustment arm frame 9 being located above the rubber wheel 150, when the adjustment arm frame 9 moves towards the rubber wheel 150, the support retaining arm 3 has a tendency to deflect downward. A magnetic block 17 is fixedly connected to the end of the adjustment arm frame 9. Combined with Figure 3 and Figure 5 It can be known that the height adjustment frames 2 are symmetrically arranged on the side of the storage support frame 1, and the magnetic blocks 17 on the two height adjustment frames 2 repel each other magnetically. In the normal state, since the magnetic blocks 17 are not blocked, under the action of the magnetic repulsion between the two, the magnetic blocks 17 are relatively far away from the transmission rod 15, and the magnetic blocks 17 force the transmission rod 15 to drive the support retaining arm 3 to deflect upward through the rubber wheel 150. At this time, the two support retaining arms 3 are relatively far away from each other.

[0035] In practical applications, in the normal state, since the magnetic blocks 17 are not blocked, the magnetic repulsion force between the two magnetic blocks 17 forces the magnetic blocks 17 to push the adjustment arm frame 9 relatively far away from the rubber wheel 150. Combined with Figure 6It can be known that when the adjusting boom 9 moves away from the rubber wheel 150, the frictional force between the adjusting boom 9 and the rubber wheel 150 forces the transmission rod 15 to deflect counterclockwise. Correspondingly, the support retaining arm 3 will deflect counterclockwise upward, and the two support retaining arms 3 move relatively away from each other. The upwardly deflected support retaining arm 3 will also not block the placement of the pipe fitting 4.

[0036] After the pipe fitting 4 is placed on the support base 7 by means of a crane or the like, since the pipe fitting 4 will also be placed between the height adjusting frames 2 at the bottom layer, the pipe fitting 4 shields the two magnets 17 at the bottom layer, thereby separating the relative magnetic surfaces of the two magnets 17. Under the elastic pulling of the adjusting spring 12, the two adjusting booms 9 will move relatively closer. At the same time, the adjusting boom 9 uses the rubber wheel 150 to drive the transmission rod 15 to drive the support retaining arm 3 to deflect towards the pipe fitting 4 until the support retaining arm 3 on the bottom layer presses against the top of the pipe fitting 4. Since the support retaining arms 3 are arranged in an "X" shape, when the bottom of the support retaining arm 3 clamps and fastens the pipe fitting 4, a "V" - shaped notch is left above. Use a crane to transport the pipe fitting 4 above the support retaining arm 3. After that, the pipe fitting 4 will again shield the upper - layer height adjusting frame 2, and so on, enabling the pipe fitting 4 to be vertically stacked in the storage support frame 1. Since each pipe fitting 4 is clamped and fastened by the support retaining arm 3, the stability of the pipe fitting 4 during ocean transportation is greatly guaranteed. Embodiment Two

[0037] Based on Embodiment One with further improvements, in order to prevent the pipe fitting 4 at the bottom layer from deforming after being subjected to excessive pressure, please refer to Figure 6It can be clearly seen that the end of the transmission rod 15 is coaxially fastened with a locking gear 151 located on one side of the rubber wheel 150. Correspondingly, the bottom bolt of the adjustment arm 9 is fastened with a locking gear row 16. When the locking gear row 16 and the locking gear 151 are engaged, the locking gear row 16 will restrict the rotation of the locking gear 151. In actual application, when the pipe 4 is placed on the support base 7, the pipe 4 is blocked between the two magnetic blocks 17, thereby isolating the relative magnetic surfaces between the two. Afterwards, the adjustment arm 9 is pulled toward the rubber wheel 150 by the elastic force of the adjustment tension spring 12, and the friction between the adjustment arm 9 and the rubber wheel 150 is used to drive the transmission rod 15 to press the support arm 3 toward the pipe 4 until the support arm 3 is pressed on the outside of the pipe 4. Afterwards, as the adjusting tension spring 12 continues to pull the adjusting arm 9 to move in the direction of the rubber wheel 150, the supporting arm 3 is restricted by the pipe 4 and cannot rotate, which causes the transmission rod 15 to drive the rubber wheel 150 and the locking gear 151 to be unable to rotate. At this time, relative sliding occurs between the adjusting arm 9 and the rubber wheel 150. As the adjusting tension spring 12 pulls, the adjusting arm 9 will eventually drive the locking gear row 16 to abut against the locking gear 151, and the locking gear 151 is restricted by the locking gear row 16 so that it cannot rotate. Finally, when the pipe 4 is placed on the supporting arm 3, although the pipe 4 presses the supporting arm 3 to make the supporting arm 3 have a tendency to further deflect downward, it is restricted by the locking gear row 16 and the locking gear 151, forcing the supporting arm 3 to be unable to deflect downward. Therefore, the blocking of the supporting arm 3 not only realizes the clamping and fixing of the pipe 4, but also provides support for the pipe 4 placed subsequently, avoiding the phenomenon that the bottom pipe 4 is compressed and deformed due to excessive stacking.

[0038] Although this method can achieve the fastening and support of the pipe 4 by locking the support arm 3, when the cargo ship transports the pipe 4 to the destination, it is difficult to unload the pipe because the support arm 3 cannot move. Figure 1 , Figure 3 and Figure 9 It can be clearly seen that the reversing wheels 500 are movably installed on the upper and lower sides of the storage support frame 1, and the outer side of the reversing wheel 500 is connected to the transmission by a connecting ring 501. The connecting ring 501 can be a pulley or a sprocket, preferably a sprocket. The side of the storage support frame 1 is tightly connected to an adjusting motor 5 coaxially fastened to the reversing wheel 500, and the adjusting motor 5 is used to drive the reversing wheel 500 to rotate, so as to realize the movement of the connecting ring 501. The connecting ring 501 is tightly connected to a fixed base 21, and a pressure roller 22 located above the adjusting arm 9 is installed on the fixed base 21. When the reversing wheel 500 drives the connecting ring 501 to move, the connecting ring 501 will drive the fixed base 21 to move up and down. Figure 6It can be seen that there is a return push seat 11 fastened by bolts at the top of the adjusting boom 9, and the surface shape of the return push seat 11 is a right triangle. An in-place indication groove 900 is formed at the top of the adjusting boom 9 on one side of the return push seat 11, and the width of the in-place indication groove 900 is greater than the diameter of the pressure roller 22.

[0039] In actual application, after the pipe fitting 4 is placed on the support base 7, the support retaining arm 3 is used to clamp the pipe fitting 4 and support the pipe fitting 4 placed later. At the same time, the return push seat 11 will move along with the adjusting boom 9 towards the transmission rod 15. Finally, the locking tooth row 16 is attached to the locking gear 151, and the inclined surface of the return push seat 11 is located below the pressure roller 22.

[0040] Under normal conditions, due to the influence of gravity, the fixed base 21 will be located at the bottommost. After the cargo ship transports the pipe fitting 4 to the destination, the adjusting motor 5 is used to drive the reversing wheel 500 counterclockwise, so that the pressure roller 22 moves above the topmost adjusting boom 9, and the adjusting motor 5 stops working. At this time, the pressure roller 22 presses downward on the inclined surface of the return push seat 11 due to gravity. The pressure roller 22 pressing the inclined surface forces the return push seat 11 to have a tendency to drive the adjusting boom 9 to move away from the transmission rod 15 until the locking tooth row 16 disengages from the locking gear 151, and the pressure roller 22 presses on the top of the adjusting boom 9. Thus, the deflection limit of the support retaining arm 3 is released.

[0041] The topmost pipe fitting 4 is lifted out by using a crane. The pipe fitting 4 lifted upward can push open the topmost support retaining arm 3, thereby completing the lifting out of the pipe fitting 4. After the pipe fitting 4 is lifted out, it will no longer block the magnet 17. Affected by the magnetic repulsion force between the magnets 17, the two adjusting booms 9 are forced to move relatively away from each other again. At this time, the support retaining arm 3 deflects upward. During the movement of the adjusting boom 9 away from the transmission rod 15, the pressure roller 22 will also move along the top of the adjusting boom 9. When the adjusting boom 9 deflects the support retaining arm 3 upward to the limit, the retraction of the support retaining arm 3 will also be completed. At this time, the in-place indication groove 900 also reaches the position of the pressure roller 22. Affected by the gravity of the pressure roller 22 itself, the pressure roller 22 is forced to pass through the in-place indication groove 900 and move downward, thereby pressing on the next return push seat 11. In this way, the pipe fittings 4 can be lifted out sequentially from the top. Finally, as the bottommost pipe fitting 4 is lifted out, the pressure roller 22 will also cross the bottommost in-place indication groove 900, and under the action of its own gravity, the fixed base 21 moves to the bottommost, that is, the above-mentioned normal position. Embodiment III

[0042] On the basis of Embodiment II, further improvements are made, in combination with Figure 1 and Figure 5It can be clearly seen that at the end of the height adjustment frame 2, there is a guiding slide seat 200 fastened by bolts. The end of the guiding slide seat 200 is in the shape of a dovetail. By making the guiding slide seat 200 correspond to the dovetail groove opened on the side of the storage support frame 1, the height adjustment frame 2 can perform a one-way reciprocating motion along the side of the storage support frame 1. A limiting tooth head 140 is movably installed on the guiding slide seat 200, and the limiting tooth head 140 can only perform a one-way reciprocating motion on the guiding slide seat 200. A limiting intermediate rod 14 is fastened to the back of the limiting tooth head 140, and one end of the limiting intermediate rod 14 is located at the top of the adjusting arm frame 9. At the same time, a limiting stop block 13 fastened by bolts is provided at the top of the adjusting arm frame 9. The surface shape of the limiting stop block 13 is a right triangle. When the adjusting arm frame 9 drives the limiting stop block 13 to move away from the transmission rod 15, the limiting stop block 13 will push the limiting intermediate rod 14 to move away from the height adjustment frame 2.

[0043] A limiting tooth row 18 is movably installed in the storage support frame 1, and a directional component 180 is arranged between the limiting tooth row 18 and the inner side of the storage support frame 1. By using the directional component 180, the limiting tooth row 18 can only perform a one-way reciprocating motion. After the limiting tooth row 18 meshes with the limiting tooth head 140, the up-and-down movement of the limiting tooth head 140 can be restricted, and further the up-and-down movement of the guiding slide seat 200 and the height adjustment frame 2 can be restricted. Regarding how the limiting tooth row 18 approaches / separates from the limiting tooth head 140, it can be clearly seen from Figure 8 that a screw rod 19 is movably installed at the bottom of the storage support frame 1, and the screw rod 19 is threadedly connected to the limiting tooth row 18. When the screw rod 19 rotates, the limiting tooth row 18 can move along the directional component 180, and finally the limiting tooth row 18 can approach / separate from the limiting tooth head 140. For the drive of the screw rod 19, two methods are given in the third embodiment of the present invention:

[0044] The first method is that a reset servo motor 8 is fastened to the side of the storage support frame 1, and the reset servo motor 8 and the screw rod 19 are coaxially fastened. By controlling the rotation direction of the reset servo motor 8, the reset servo motor 8 can drive the screw rod 19 to perform a directional rotation, so as to achieve automatic regulation.

[0045] The second method is that one end of the screw rod 19 is fastened with a control handle 6, and a limiting indicator frame 600 is fixedly installed on the side of the storage support frame 1. By manually turning the control handle 6 up and down, the screw rod 19 can be rotated. The limiting indicator frame 600 can not only limit the movement stroke of the control handle 6, but also reflect the deflection angle of the control handle 6, so that the operator can accurately control the deflection angle.

[0046] The above two methods can be applied separately or in combination.

[0047] More importantly, since two limit tooth rows 18 are symmetrically arranged on the storage support frame 1, in order to ensure the synchronous movement between the two limit tooth rows 18, a synchronous connection frame 20 is fixedly connected to the bottom of the limit tooth rows 18 by bolts. The synchronous connection frame 20 can be used to achieve the synchronous movement of the limit tooth rows 18, thereby ensuring the synchronism of motion control.

[0048] During the actual transportation process, due to different types of transported pipes, problems of different pipe diameters will occur. In order to ensure better fastening between the pipes, it is crucial to control the distance between the height adjustment frames 2. Generally, the distance between the height adjustment frames 2 is preferably controlled to be the diameter length of the transported pipe, so that the center of the pipe fitting 4 and the height adjustment frame 2 can be relatively flush, ensuring that the deflection angles of each support arm 3 are relatively constant, and thus ensuring the stability of pipe transportation. In order to solve the problem of adjusting the distance between the height adjustment frames 2, combined with Figure 7 It can be seen that when there is no occlusion between the magnetic blocks 17, the magnetic repulsive force of the magnetic blocks 17 causes the adjusting arm frame 9 to move away from the transmission rod 15 until the limiting block 13 abuts against the end of the limit intermediate rod 14. At this time, the support arm 3 is retracted, and the in-place indication groove 900 and the pressure roller 22 are vertically aligned.

[0049] When it is necessary to adjust the distance between the height adjustment frames 2, the screw rod 19 is rotated by using the control handle 6 or the reset servo motor 8. Combined with Figure 2 As shown, the control handle 6 is deflected counterclockwise to the upper limit position, and the control handle 6 abuts against the inner side of the limit indication frame 600. At this time, the limit tooth row 18 is rotated by the screw rod 19 to move away from the limit tooth head 140. Then, the magnetic repulsive force between the magnetic blocks 17 causes the adjusting arm frame 9 to push the limiting block 13 through the limit intermediate rod 14, forcing the limit intermediate rod 14 to push the limit tooth head 140 closer to the limit tooth row 18. Combined with Figure 6 It can be seen that when the locking tooth row 16 abuts against the inner side of the height adjustment frame 2, the adjusting arm frame 9 can no longer move again. At this time, the limit tooth head 140 and the limit tooth row 18 are disengaged. Then, under the action of the self-weight of the height adjustment frame 2, it moves downward, causing multiple height adjustment frames 2 to be stacked vertically together. During this process, in order to prevent collisions between the height adjustment frames 2, combined with Figure 6 It can be seen that an anti-collision cylinder 10 is fixedly connected to the top of the height adjustment frame 2. By using the buffering of the anti-collision cylinder 10, the collision between the height adjustment frames 2 can be buffered.

[0050] After that, the adjustment motor 5 is used to drive the reversing wheel 500 to rotate clockwise, so that the pressure roller 22 moves upward. As described above, when the adjustment arm 9 abuts against the inclined surface of the limit stop 13, the adjustment arm 9 pushes the in-place indicating groove 900 to move away from the transmission rod 15. At this time, the in-place indicating groove 900 will no longer be vertically aligned with the pressure roller 22. When the connecting ring 501 pulls the pressure roller 22 upward by using the fixed base 21, the pressure roller 22 will abut against the bottom of the adjustment arm 9, and then use the adjustment arm 9 to push the bottom height adjustment frame 2 upward. During this process, the height adjustment frame 2 moves upward synchronously. When the bottom height adjustment frame 2 reaches the required height, the screw 19 is screwed by using the control handle 6 or the reset servo motor 8, so that the control handle 6 deflects downward to the limit again. At this time, the limit tooth row 18 will abut against the limit tooth head 140, not only restricting the movement of the guide slide 200 and the height adjustment frame 2 by using the limit tooth head 140, but also pushing the limit intermediate rod 14 further against the limit stop 13 by using the limit tooth head 140. When the limit intermediate rod 14 abuts against the inclined surface of the limit stop 13, it will push the adjustment arm 9 to move towards the transmission rod 15, that is, the adjustment arm 9 pulls the in-place indicating groove 900 to be vertically aligned with the pressure roller 22, and the pressure roller 22 passes through the in-place indicating groove 900 and moves upward. When the pressure roller 22 passes through the lowermost in-place indicating groove 900, the screw 19 is rotated again by using the control handle 6 or the reset servo motor 8, so that the limit tooth row 18 moves relatively away from the limit tooth head 140, but at this time the control handle 6 does not deflect to the limit. When the limit tooth row 18 contacts the limit tooth head 140, the limit tooth row 18 can provide support for the limit tooth head 140. When the upward movement force of the height adjustment frame 2 is too large, the limit tooth head 140 will also push the limit intermediate rod 14 towards the limit stop 13, and finally the limit tooth head 140 can move upward along the limit tooth row 18. Regarding the fact that the limit tooth row 18 and the limit tooth head 140 can ensure fastening and relative movement between the two, therefore, the tooth shapes of the two are preferably isosceles triangle shapes, so as to meet the requirement that after the upward movement strength of the limit tooth head 140 is relatively large, the limit tooth head 140 and the limit tooth row 18 can be relatively separated.

[0051] As the connecting ring 501 drives the pressure roller 22 to continuously move upward, the pressure roller 22 will contact the bottom of the next adjustment arm 9, and the pressure roller 22 will push the adjustment arm 9 upward to achieve the upward movement of the height adjustment frame 2. When the height adjustment frame 2 reaches the required height, the control handle 6 or the reset servo motor 8 is used to achieve the tightening between the limit tooth row 18 and the limit tooth head 140 again, and the cycle is repeated to ensure that the height adjustment frames 2 can be arranged autonomously according to the controllable spacing. Finally, when all the height adjustment frames 2 are arranged, the control handle 6 is used to deflect downward to the limit, forcing the limit tooth row 18 and the limit tooth head 140 to fit tightly, ensuring that the spacing between the height adjustment frames 2 can be stably maintained after adjustment. As the reversing wheel 500 rotates, the pressure roller 22 finally moves to the bottom, and the spacing adjustment between the height adjustment frames 2 is completed. Embodiment 4

[0052] Further improvements based on Example 3 are provided. Figure 9 and Figure 10 It can be seen that one end of the pressure roller 22 is movably installed in the fixed base 21 via a slider, and the pressure roller 22 is moved up and down in the fixed base 21 by the slider. A top spring 220 is connected between the slider and the fixed base 21, and a stop switch 23 is fixedly installed on the inner side of the fixed base 21. The slider is pushed by the top spring 220 and always has a tendency to move away from the stop switch 23. The stop switch 23 can control the adjustment motor 5 to stop working. Specifically, the stop switch 23 will generate an electrical signal when it is pressed and input into the control system. The control system takes a PLC programming controller as an example. After receiving the signal, the control system will output a signal to the adjustment motor 5 to stop the adjustment motor 5. When the stop switch 23 is released from pressure, the control system will also make the adjustment motor 5 work again.

[0053] The advantage of this arrangement is that when the pressure roller 22 pushes the adjusting arm 9 to move upward, the pressure roller 22 uses the adjusting arm 9 to push the height adjustment frame 2 to move upward along the storage support frame 1. During this process, the pressure roller 22 uses the slider to squeeze the top spring 220, but under the action of the elastic force of the top spring 220, the slider will not squeeze the stop switch 23.

[0054] When the screw 19 rotates and causes the limiting tooth row 18 to squeeze the limiting tooth head 140, the height of the height adjustment frame 2 will be locked. During this process, although the connecting ring 501 continues to pull the pressure roller 22 upward, if the in-position indicator groove 900 does not move to the pressure roller 22 in time during the limiting process of the height adjustment frame 2, the pressure roller 22 will further press the slider, causing the stop switch 23 to be pressed, and the stop switch 23 inputs an electrical signal to the control system, thereby stopping the adjustment motor 5 from working, ensuring that the in-position indicator groove 900 has enough time to move to the pressure roller 22, and preventing the pressure roller 22 from moving up too fast and getting stuck under the adjustment arm 9.

[0055] Combined Figure 3 It can be seen that since the connecting ring members 501 are symmetrically arranged on the side of the storage support frame 1 and the lower reversing wheels 500 are connected by a transmission shaft rod, the two reversing wheels 500 move upward synchronously. If the two height adjusting frames 2 are not at the horizontally aligned heights during the upward movement of the pressure roller 22, the magnetic surfaces between the two magnets 17 will no longer face each other. Therefore, under the pulling force of the adjusting spring 12, the adjusting arm 9 will be forced to move towards the transmission rod 15, and the limiting block 13 will also follow the adjusting arm 9 away from the limiting intermediate rod 14. At this time, the limiting block 13 and the limiting intermediate rod 14 are no longer in contact, and the in-place indicating groove 900 is relatively far from the pressure roller 22. The pressure roller 22 is below the position of the return push seat 11. Even if the limiting tooth row 18 is attached to the limiting tooth head 140, the adjusting arm 9 will not move. The upward moving pressure roller 22 will continuously abut against the bottom of the adjusting arm 9 (i.e., below the position where the return push seat 11 is located). Therefore, when the height adjusting frame 2 is pushed to the required height, if the two height adjusting frames 2 are not horizontally aligned, the pressure roller 22 will continuously abut against the bottom of the adjusting arm 9. After the limiting tooth row 18 and the limiting tooth head 140 are close to each other and lock the height adjusting frame 2, the pressure roller 22 still abuts against the lower part of the adjusting arm 9. As the fixed base 21 moves upward, the pressure roller 22 presses the stop switch 23 downward through the slider, and finally stops the adjusting motor 5 from working. When the adjusting motor 5 stops working, it indicates that the height adjusting frames 2 are not aligned, and the operator needs to check this.
