An intelligent auxiliary transfer platform for shipborne cargo loading and unloading

Abstract

This application relates to the technical field related to cargo loading, and discloses an intelligent shipborne cargo loading and unloading auxiliary transfer platform. To solve the problem that the steel wire rope is prone to swing due to environmental factors during cargo loading and unloading, an anti-sway arm is installed on the transfer frame. When the lifting connection frame moves up and down under the traction of the pull rope, the relative movement between the lifting connection frame and the transfer frame forces the anti-sway arm to insert into the guide seat, so that the transfer frame can drive the cargo to move up and down only along the side of the transport ship. Since the transfer frame and the transport ship move synchronously, it is avoided that the transfer frame swings and impacts the transport ship; at the same time, when the transfer frame falls onto the gangway, the anti-sway arm will retract automatically, so that when the transfer frame is loading and unloading cargo on the gangway, the swing of the transport ship will not affect it, and finally a stable lifting and stable loading and unloading effect are achieved.

Description

Technical Field

[0001] This application relates to the technical field of cargo loading, and particularly to an intelligent shipborne cargo loading and unloading auxiliary transfer platform. Background Art

[0002] The shipborne cargo loading and unloading auxiliary transfer platform is a highly specialized device designed to optimize and enhance the efficiency and safety of shipborne cargo loading and unloading. It not only provides a suitable height and stable support matching various transportation tools such as ships, trucks, and containers, but also incorporates advanced stabilization technologies and automated control systems to ensure the rapid and smooth transfer of cargo between different transportation links.

[0003] Traditionally, these transfer platforms are mainly deployed in cargo concentration areas such as ports and docks, requiring the transport ships to approach specific positions for loading and unloading operations, which to a certain extent limits the flexibility and efficiency of the operations. To overcome this limitation, modern shipborne cargo loading and unloading auxiliary transfer platforms tend to be integrated with the transport hull for closer docking and more efficient operation processes. However, in the face of complex marine environments, such as natural factors like strong winds, large waves, and tidal changes, the traditional wire rope lifting method often faces challenges during the cargo exchange process. The swaying of the cargo not only affects the loading and unloading efficiency but may also cause damage to the cargo itself and the hull structure. Summary of the Invention

[0004] This application proposes an intelligent shipborne cargo loading and unloading auxiliary transfer platform, which has the advantages of stable lifting and stable loading and unloading, to solve the problem of easy swaying when using wire ropes for loading and unloading as mentioned in the above background art.

[0005] To achieve the above object, this application adopts the following technical solutions: An intelligent shipborne cargo loading and unloading auxiliary transfer platform, comprising: a transport ship, with a transfer platform fixed on the side, a hoist installed on the transfer platform, and a pull rope and a control handle installed on the hoist; a transfer rack, with a lifting connection frame installed on the surface, the top of the lifting connection frame is movably connected to the pull rope, a lifting tooth row is fixedly connected to the side of the lifting connection frame, a driving gear meshing with the outer teeth of the lifting tooth row is movably installed at the bottom of the transfer rack, and a driven gear is coaxially and fixedly installed on the driving gear, and an anti-sway arm meshing with the driven gear is movably installed at the bottom of the transfer rack; a guide seat, fixed on the side of the transport ship.

[0006] Further, a raised inclined surface is provided in the middle of the outer side of the guide seat, a guide groove is provided on the guide seat, and a rectangular channel is provided on the side of the guide groove.

[0007] Further, support bases are symmetrically and fixedly installed on both sides of the bottom of the transfer rack.

[0008] Furthermore, a fixed retaining frame is connected to the surface of the transfer rack. An adjustable retaining frame and a limiting box are movably installed on the surface of the transfer rack, and the limiting box and the adjustable retaining frame move synchronously. An anti-disengagement tension spring is connected between the side of the limiting box and the end of the anti-sway arm.

[0009] Furthermore, hydraulic cylinders are symmetrically arranged on the surface of the transfer platform, and locking sleeves facing the limiting box are symmetrically arranged on the surface of the transfer rack.

[0010] Furthermore, an anti-disengagement tooth row pull seat is movably arranged in the anti-sway arm, and a locking tongue is fixedly connected to the end of the anti-disengagement tooth row pull seat.

[0011] Furthermore, a one-way limiting tooth row is arranged in the limiting box.

[0012] Furthermore, there are two anti-disengagement tooth row pull seats. A connecting telescopic tube is movably installed between the two anti-disengagement tooth row pull seats. Unlocking cone seats are fixedly installed at both ends of the connecting telescopic tube respectively. A connecting tension spring located outside the connecting telescopic tube is connected between the unlocking cone seats. An unlocking sleeve is coaxially arranged outside the connecting telescopic tube, and both ends of the unlocking sleeve abut against the unlocking cone seats respectively; an unlocking push seat is arranged at the top of the rectangular channel in the guide seat.

[0013] Furthermore, the one-way limiting tooth row is movably installed in the limiting box, and a limiting top spring is connected between the one-way limiting tooth row and the limiting box.

[0014] Furthermore, detection retaining frames are movably installed at the outer bottom of both the fixed retaining frame and the adjustable retaining frame; there are two limiting boxes. One is tightly connected to the adjustable retaining frame through an anti-disengagement connecting frame. A connecting pull rod is fixedly installed at the side of the other limiting box, and the end of the connecting pull rod is located between the detection retaining frame and the adjustable retaining frame; a one-way air valve and a pneumatic horn are fixedly installed at the top of the limiting box.

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

[0016] An intelligent shipborne cargo loading and unloading auxiliary transfer platform provided by the present application is equipped with an anti-sway arm structure on the transfer rack. When the lifting connecting frame is precisely controlled to move up and down through a high-strength pull rope, it will force the anti-sway arm to automatically insert into the preset guide seat. This mechanism ensures that the transfer rack can run smoothly along the side track of the transport ship when driving the cargo to lift and lower, effectively eliminating the sway problem caused by natural factors (such as wind, waves, tides) or water flow in the traditional loading and unloading method, thereby avoiding potential damage to the transport ship and the cargo.

[0017] More importantly, when the transfer rack safely lands on the gangway of the port or dock, the anti-sway arm can intelligently sense and automatically retract. This feature enables the transfer rack to be completely unaffected by any sway that may occur on the transport ship during the loading and unloading operation on the gangway, ensuring the continuity and stability of the entire loading and unloading process.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without making creative efforts belong to the scope of protection of the present application. Embodiment 1

[0034] Please refer to Figure 1 and Figure 2 It can be seen that a transfer platform 2 is fixedly installed on the side of the transport ship 1, and a hoist 4 is fixedly supported on the surface of the transfer platform 2 by a U-shaped steel. A pulling rope 401 is installed on the hoist 4, and the hoist 4 can be controlled by the control handle 400 to wind / unwind the pulling rope 401. As Figure 2 shown, lifting connecting frames 7 are movably installed at the four corners of the surface of the transfer rack 3, and the top of the lifting connecting frame 7 is movably connected to the pulling rope 401 by a roller. When the pulling rope 401 is wound, the transfer rack 3 is pulled upward by the lifting connecting frame 7; similarly, when the pulling rope 401 is unwound, the transfer rack 3 is lowered. In order to ensure the stability of the movement of the transfer rack 3, combined with Figure 2 it can be seen that there are two hoists 4, and pulling ropes 401 for pulling the lifting connecting frames 7 to move up and down are arranged on both hoists 4. Therefore, using the two hoists 4 to pull the transfer rack 3 up and down can ensure the stability of its movement. More specifically, since the control handle 400 can control the two hoists 4 to work, under normal conditions, the two hoists 4 work synchronously, but after the transfer rack 3 is relatively inclined, the control handle 400 is used to control the two hoists 4 to rotate differentially, so that the winding / unwinding rates of the two pulling ropes 401 change, thereby correcting the inclination of the transfer rack 3 to a certain extent and ensuring the stability of its movement.

[0035] During actual application, the transport ship 1 will sway under the influence of external environmental factors, which causes the elevator 4 on the transport ship 1 to also sway accordingly. When the goods are placed on the transfer rack 3, if there is relative sway between the transfer rack 3 and the transport ship 1, it is easy for the transfer rack 3 to hit the side of the transport ship 1, resulting in damage to the transport ship 1 or the goods. In order to ensure the stability of the transfer rack 3 when transporting goods in the first embodiment, combined with Figure 2 , Figure 4 and Figure 5 It can be seen that a lifting tooth row 700 is fixedly connected to the side of the lifting connection frame 7. Correspondingly, a driving gear 14 that meshes with the external teeth of the lifting tooth row 700 is movably installed at the bottom of the transfer rack 3, and the driving gear 14 and the driven gear 15 are coaxially fixed. When the lifting connection frame 7 moves vertically along the transfer rack 3, the transmission between the lifting tooth row 700 and the driving gear 14 forces the driving gear 14 to drive the driven gear 15 to rotate. A sway prevention arm 13 that meshes with the driven gear 15 is movably installed at the bottom of the transfer rack 3. When the driven gear 15 rotates, the sway prevention arm 13 can be extended and retracted on the transfer rack 3. More specifically, referring to Figure 5 It can be seen that the gear diameter of the driven gear 15 is larger than that of the driving gear 14. When the driving gear 14 and the driven gear 15 rotate synchronously, the driving gear 14 rotating one circle can increase the telescopic stroke of the sway prevention arm 13 by using the driven gear 15, so that within the limited up and down movement stroke of the lifting connection frame 7, the sway prevention arm 13 can be extended and retracted by a sufficient length. Since the extension and retraction of the sway prevention arm 13 are based on the up and down movement state of the lifting connection frame 7, combined with Figure 5 It can be seen that when the lifting connection frame 7 moves upward, the lifting tooth row 700 will force the driving gear 14 to drive the driven gear 15 to rotate clockwise, thereby realizing the extension of the sway prevention arm 13; similarly, when the lifting connection frame 7 moves downward, the sway prevention arm 13 will retract towards the transfer rack 3, thereby ensuring that the movement direction of the sway prevention arm 13 is stable and controllable. Further, the number of the sway prevention arms 13 is two, and the two sway prevention arms 13 are symmetrically arranged, and correspondingly, the number of the driving gear 14 and the driven gear 15 is the same. When the lifting connection frame 7 moves up and down, the two sway prevention arms 13 are extended and retracted synchronously.

[0036] In order to guide the movement of the sway prevention arm 13, combined with Figure 2 and Figure 3It can be clearly seen that a guiding seat 6 located below the transfer platform 2 is fixedly connected to the side of the transport ship 1. A convex inclined surface is provided in the middle of the outer side of the guiding seat 6, and the included angle between the two inclined surfaces is between 90° and 175°. At the same time, two vertically arranged guiding grooves are formed on the guiding seat 6, and the distance between the two guiding grooves corresponds to the distance between the anti-sway arms 13. When the anti-sway arms 13 move towards the guiding seat 6, by the guiding of the convex inclined surface in the middle of the guiding seat 6, the ends of the anti-sway arms 13 can be stably inserted into the guiding grooves.

[0037] During specific implementation, when the goods on the transport ship 1 need to be unloaded, first dock the transport ship 1 on one side of the plank road for transporting goods, and the transfer platform 2 is located above the plank road. Use the control handle 400 to control the two hoists 4 to perform the winding work synchronously, so that the pulling rope 401 drives the transfer rack 3 to move upward through the lifting connection frame 7. Since the lifting connection frame 7 pulls the transfer rack 3 upward relatively, the lifting tooth row 700 will cause the driving gear 14 to drive the driven gear 15 to rotate, and the driven gear 15 will extend the anti-sway arms 13 towards the transport ship 1. After passing through the convex inclined surface in the middle of the guiding seat 6, the anti-sway arms 13 are inserted into the guiding grooves, and the stable upward movement of the transfer rack 3 is realized by using the guiding grooves until the top surface of the transfer rack 3 is aligned with the surface of the transport ship 1. At this time, the goods (usually containers) on the transport ship 1 are transported onto the transfer rack 3 by a forklift.

[0038] Use the control handle 400 to control the hoist 4 to release the pulling rope 401, so that the transfer rack 3 drives the goods to move downward. Since the anti-sway arms 13 always move along the guiding grooves, the relative sway between the transfer rack 3 and the transport ship 1 is reduced. If the transfer rack 3 falls normally, the transfer rack 3 will finally fall onto the plank road below; if the transfer rack 3 tilts during the falling process, use the control handle 400 to control the wire release rates of the two hoists 4 to correct the tilt of the transfer rack 3 and prevent the goods on the transfer rack 3 from accidentally falling.

[0039] When the transfer rack 3 arrives at the plank road, combined with Figure 4It can be seen that support bases 300 are symmetrically and fixedly installed on both sides of the bottom of the transfer rack 3. The support bases 300 will first come into contact with the plank road. As the hoist 4 continuously releases the pulling rope 401, the pulling force on the lifting connection frame 7 decreases. Under its own gravity, it will move downward along the transfer rack 3. The lifting gear row 700 is used to push the driving gear 14 to rotate counterclockwise, and the driven gear 15 drives the anti-sway arm 13 to retract into the transfer rack 3, and the anti-sway arm 13 moves away from the transport ship 1. At this point, it can be seen that the lifting connection frame 7 and the hoist 4 are connected by the pulling rope 401. When the pulling rope 401 is relaxed, the swinging motion of the hoist 4 will not be transmitted to the transfer rack 3 through the pulling rope 401. Combined with the anti-sway arm 13 disengaging from the guiding seat 6, the swinging of the transport ship 1 will not be transmitted to the transfer rack 3 either. At this time, the transfer rack 3 placed on the plank road and the transport ship 1 do not interfere with each other, and the goods on the transfer rack 3 can be unloaded by a forklift on the plank road.

[0040] When loading goods onto the transport ship 1, in the same way as above, place the goods on the plank road on the transfer rack 3 and use the pulling rope 401 to pull the lifting connection frame 7 upward until the top of the transfer rack 3 is aligned with the surface of the transport ship 1, and then use the forklift on the transport ship 1 to unload the goods on the transfer rack 3. Embodiment 2

[0041] On the basis of Embodiment 1, for further improvement, in order to fix the goods on the transfer rack 3 and prevent the goods from detaching from the transfer rack 3 during hoisting, please refer to Figure 4 and Figure 5 It can be seen that a fixed stop frame 9 is fixedly connected to the surface of the transfer rack 3 and near one side of the driven gear 15. The number of the fixed stop frames 9 is two, and the two fixed stop frames 9 are symmetrically arranged on the transport ship 1, so as to use the fixed stop frames 9 to block the goods and prevent the goods from detaching from the transfer rack 3 during hoisting. At the same time, a movable stop frame 8 opposite to the fixed stop frame 9 is movably installed on the surface of the transfer rack 3. The number of the movable stop frames 8 is also two, and the two movable stop frames 8 are both movable along the surface of the transfer rack 3, so as to approach / leave the fixed stop frame 9, facilitating the clamping / relaxing of the goods.

[0042] To ensure the stability of clamping, as can be seen from Figures 6 - 8 , a limit box 12 is movably installed on the surface of the transfer rack 3 on one side of the movable stop frame 8, and the limit box 12 and the movable stop frame 8 are fixed by an anti-disengagement connecting frame 801. An anti-disengagement pulling spring 16 is connected between the side part of the limit box 12 and the end part of the anti-sway arm 13. When the anti-sway arm 13 extends outwards, it will pull the limit box 12 to move synchronously, and the limit box 12 will pull the movable stop frame 8 to approach the fixed stop frame 9 through the anti-disengagement connecting frame 801, as shown in Figure 12As shown in the figure, when goods are clamped between the movable retaining frame 8 and the fixed retaining frame 9, the goods will restrict the movement of the movable retaining frame 8, causing the anti-disengagement spring 16 to stretch and the movable retaining frame 8 to closely adhere to the side of the goods.

[0043] When the transfer rack 3 is placed on the trestle, since the lifting connecting frame 7 moves downward along the transfer rack 3, the anti-sway arm 13 is retracted into the transfer rack 3, and the limiting box 12 is pushed relatively away from the fixed retaining frame 9. The movable retaining frame 8 also moves relatively away from the fixed retaining frame 9. At this time, the distance between the movable retaining frame 8 and the fixed retaining frame 9 is the largest, facilitating the loading and unloading of goods. When the lifting connecting frame 7 pulls the transfer rack 3 for lifting, the anti-sway arm 13 is pushed out and pulls the movable retaining frame 8 to closely adhere to the goods. As the anti-sway arm 13 is continuously pushed outwards, the anti-disengagement spring 16 is tightened. At this time, the goods can be clamped by the movable retaining frame 8 and the fixed retaining frame 9, preventing the goods from detaching from the transfer rack 3 during lifting and ensuring the stability during transportation.

[0044] On this basis, combined with Figure 1 、 Figure 2 and Figure 4 It can be seen that hydraulic cylinders 5 are symmetrically arranged on the surface of the transfer platform 2. Correspondingly, locking sleeves 500 facing the limiting box 12 are symmetrically arranged on the surface of the transfer rack 3, and the inner diameter of the locking sleeve 500 is slightly larger than the diameter of the hydraulic oil rod of the hydraulic cylinder 5. After the hoist 4 pulls the lifting connecting frame 7 upward through the pull rope 401, finally, the top of the transfer rack 3 is aligned with the surface of the transport ship 1. The hydraulic oil rod of the hydraulic cylinder 5 is passed through the locking sleeve 500, and the limiting box 12 is pushed to move away from the fixed retaining frame 9. The limiting box 12 will further stretch the anti-disengagement spring 16. At the same time, the movable retaining frame 8 releases the pressing on the goods, making it easy to unload the goods on the transfer rack 3 into the transport ship 1. For safety considerations, since the hydraulic oil rod of the hydraulic cylinder 5 passes through the locking sleeve 500, when the goods are loaded and unloaded on the transfer rack 3, relative movement between the transfer rack 3 and the transport ship 1 is avoided. When goods are loaded and unloaded between the transfer rack 3 and the transport ship 1, the stability of their positions can be ensured, greatly guaranteeing the safety of loading and unloading. Embodiment Three

[0045] On the basis of Embodiment Two, further improvement is made. Since the movable retaining frame 8 is fixed only by the elastic tension of the anti-disengagement spring 16, if the shaking of the goods on the transfer rack 3 is relatively large, it is easy to cause the instantaneous thrust of the goods on the movable retaining frame 8 to be greater than the elastic tension of the anti-disengagement spring 16. At the same time, when the transport ship 1 sways along the direction of the anti-sway arm 13, it is easy to cause the anti-sway arm 13 to disengage from the guide seat 6. In order to further ensure the stability of the goods during lifting, please refer to Figures 6 - 8 and Figure 11It can be seen that an anti-disengagement tooth row pull seat 10 is movably arranged in the anti-sway arm 13, and the locking tongue 1001 fixedly connected to the end of the anti-disengagement tooth row pull seat 10 extends from the end of the anti-sway arm 13. The anti-disengagement tooth row pull seat 10 can only perform a single-line reciprocating movement along the anti-sway arm 13 under the guidance of the locking tongue 1001. Since the locking tongue 1001 is installed at the end of the anti-sway arm 13, when the anti-sway arm 13 moves towards the transport ship 1, it will drive the anti-disengagement tooth row pull seat 10 to move synchronously. Combined with Figure 3 It can be seen that the locking tongue 1001 will extend into the guiding groove of the guiding seat 6. A rectangular channel is arranged on the side of the guiding groove. The locking tongue 1001 is used to hook into the rectangular channel to further limit the anti-sway arm 13 to only perform an up-and-down reciprocating movement along the guiding seat 6.

[0046] There are two anti-sway arms 13, and there are also two anti-disengagement tooth row pull seats 10. Combined with Figure 10 and Figure 11 It can be seen that a connecting telescopic pipe 19 is movably installed between the two anti-disengagement tooth row pull seats 10. Unlocking cone seats 18 are fixedly installed at both ends of the connecting telescopic pipe 19 respectively. The two unlocking cone seats 18 are correspondingly installed on the two anti-disengagement tooth row pull seats 10 to ensure that the unlocking cone seats 18 move synchronously with the anti-disengagement tooth row pull seats 10. A connecting tension spring 190 is connected between the unlocking cone seats 18 and is located outside the connecting telescopic pipe 19. Under the tension of the connecting tension spring 190, the two unlocking cone seats 18 are forced to drive the anti-disengagement tooth row pull seats 10 to approach each other. An unlocking sleeve 11 is coaxially arranged outside the connecting telescopic pipe 19, and both ends of the unlocking sleeve 11 abut against the unlocking cone seats 18 respectively. Refer to Figure 12 It can be seen that the unlocking sleeve 11 is slightly lower than the bottom of the support base 300. This arrangement enables the transfer rack 3 to make the unlocking sleeve 11 contact the plank first when it touches the plank, and through the extrusion of the plank on the unlocking sleeve 11, the two unlocking cone seats 18 are pushed away from each other, causing the unlocking cone seats 18 to drive the locking tongue 1001 to disengage from the rectangular channel through the anti-disengagement tooth row pull seat 10. Since the two anti-disengagement tooth row pull seats 10 move synchronously by means of the connecting telescopic pipe 19, the two anti-disengagement tooth row pull seats 10 further limit the synchronous movement of the anti-sway arms 13, ensuring that when the anti-sway arms 13 cooperate with the guiding seat 6, the anti-sway arms 13 can be inserted into the guiding groove synchronously.

[0047] Furthermore, refer to Figure 2It can be seen that a one-way limiting tooth row 17 is arranged in the limit box 12. When the anti-slip tooth row pull seat 10 and the one-way limiting tooth row 17 are engaged, the movement of the limit box 12 can be limited, and the position of the movable blocking frame 8 is further limited by the anti-slip connecting frame 801. Specifically, when the transfer frame 3 is placed on the plank road for loading goods and the supporting base 300 is placed on the plank road, the unlocking sleeve 11 is pressed against the plank road. When the unlocking sleeve 11 is pressed, the unlocking cone seat 18 is forced to move relatively apart, and the two anti-slip tooth row pull seats 10 are correspondingly relatively apart. At this time, the anti-slip tooth row pull seat 10 is separated from the one-way limiting tooth row 17, and the movement of the limit box 12 is not affected. The control handle 400 controls the hoist 4 to reel in the pull rope 401, so that the pull rope 401 lifts the lifting connection frame 7 upward. As the lifting gear row 700 goes up, the anti-sway arm 13 is extended outward through the driving gear 14 and the driven gear 15 until the anti-sway arm 13 is extended to the limit. The outwardly extended anti-sway arm 13 will pull the anti-detachment tension spring 16, forcing the limit box 12 to push the movable retaining frame 8 to fit tightly against the cargo through the anti-detachment connection frame 801. When the anti-sway arm 13 is extended to the limit, the anti-detachment tension spring 16 is elastically stretched to the maximum, and the movable retaining frame 8 is closely attached to the cargo to prevent the cargo from moving on the transfer frame 3. During this process, the support base 300 has not yet separated from the plank road, combined with Figure 5 It can be seen that when the lifting connection frame 7 moves upward to the limit, the side of the lifting connection frame 7 will hook the support base 300, thereby pulling the support base 300 to move upward synchronously.

[0048] When the transfer rack 3 moves upward, the unlocking sleeve 11 also disengages from the plank road immediately. Affected by the elastic pull of the connecting tension spring 190, the anti-detachment tooth row pull seats 10 are forced to approach each other, and the anti-detachment tooth row pull seats 10 and the one-way limiting tooth row 17 are engaged and locked. Since the anti-detachment tooth row pull seats 10 move with the anti-sway arm 13, therefore, by locking the limiting box 12 with the anti-detachment tooth row pull seats 10, the fixing strength of the movable retaining frame 8 is further ensured. As the transfer rack 3 is lifted and the anti-sway arm 13 extends to the limit, the end of the anti-sway arm 13 will approach the guide seat 6. After being guided by the convex slope of the guide seat 6, the anti-sway arm 13 is inserted into the guide groove of the guide seat 6. At the same time, the lock tongue 1001 will also retract into the anti-sway arm 13 under the influence of the convex slope. When the lock tongue 1001 reaches the rectangular channel, affected by the elastic pull of the connecting tension spring 190, the lock tongue 1001 is forced to insert into the rectangular channel, so as to ensure that the transfer rack 3 can only move up and down reciprocally along the guide seat 6. When the lock tongue 1001 contacts the convex slope, there will be a state where the anti-detachment tooth row pull seats 10 and the one-way limiting tooth row 17 are briefly disengaged. In order to prevent the limiting box 12 from shifting during this process, in practical applications, the two lock tongues 1001 can be staggered relative to each other so that they pass through the convex slope of the guide seat 6 in sequence, that is, one lock tongue 1001 enters the rectangular channel first, and the other enters later, so as to ensure that at least one pair of the anti-detachment tooth row pull seats 10 and the one-way limiting tooth row 17 are always in a state of meshing and locking.

[0049] After the transfer rack 3 moves upward to the top, it is necessary to release the lock on the movable retaining frame 8. Combining Figure 3 It can be seen that an unlocking push seat 600 is provided at the top of the rectangular channel in the guide seat 6. The cross-sectional shape of the unlocking push seat 600 is a right trapezoid. When the lock tongue 1001 passes through the unlocking push seat 600, the lock tongue 1001 is affected by the trapezoidal slope to push the two anti-detachment tooth row pull seats 10 away from each other, so as to release the movement restriction on the limiting box 12. However, during this process, the lock tongue 1001 will not disengage from the rectangular channel. Finally, the hydraulic cylinder 5 passes through the locking sleeve 500 and pushes the movable retaining frame 8 away from the fixed retaining frame 9 to release the elastic clamping restriction on the goods. Embodiment Four

[0050] On the basis of Embodiment Three, a further improvement is made. Please refer to Figure 6 and Figure 7It can be seen that the one-way limiting gear row 17 is movably installed in the limiting box 12, and a limiting top spring 170 is connected between the one-way limiting gear row 17 and the limiting box 12. The tooth shape of the one-way limiting gear row 17 is a right triangle, having a one-way locking characteristic. When the goods on the transfer rack 3 become loose during the hoisting process, since the anti-detachment tension spring 16 is always in a tensioned state, therefore, by using the elastic stretching of the anti-detachment tension spring 16, the limiting box 12 can move along the anti-detachment gear row seat 10, thereby further completing the locking work of the goods and ensuring that the goods can be relatively stable during hoisting.

[0051] On this basis, in combination with Figure 6 , Figure 8 and Figure 9 It can be seen that detection brackets 800 are movably installed at the outer bottom of both the fixed bracket 9 and the movable bracket 8, and the detection brackets 800 can move up and down. In order to ensure the synchronization of the movement of the four detection brackets 800, the two detection brackets 800 on the movable bracket 8 and the two detection brackets 800 on the fixed bracket 9 are fixed by connecting rods, and the detection brackets 800 on the movable bracket 8 and the fixed bracket 9 are fixed by telescopic rods to ensure the synchronous movement between the detection brackets 800. At the same time, since there are two limiting boxes 12, one is firmly connected between the anti-detachment connecting frame 801 and the movable bracket 8, and a connecting pull rod 20 is fixedly installed on the side of the other limiting box 12, and the end of the connecting pull rod 20 is located between the detection bracket 800 and the movable bracket 8. Under normal conditions, when the detection bracket 800 moves downward, the connecting pull rod 20 is restricted between the movable bracket 8 and the detection bracket 800, thereby ensuring that the movement of the limiting box 12 can drive the movable bracket 8 to move synchronously. When the detection bracket 800 moves upward, the restriction on the connecting pull rod 20 will be released, enabling the connecting pull rod 20 and the movable bracket 8 to be relatively separated. Regarding the reset of the connecting pull rod 20 to between the movable bracket 8 and the detection bracket 800, in combination with Figure 9 It can be clearly seen that a slope is provided at the bottom of the detection bracket 800. When the connecting pull rod 20 abuts against the slope, it will push the detection bracket 800 to move upward, thereby enabling the connecting pull rod 20 to enter between the movable bracket 8 and the detection bracket 800 again.

[0052] Referring to Figure 7 It can be seen that a one-way air valve 121 for unidirectionally supplying air into the limiting box 12 is fixedly installed at the top of the limiting box 12, and a pneumatic horn 122 is fixedly installed at the top of the limiting box 12. When the air flow inside the limiting box 12 is output outward, the air flow passes through the pneumatic horn 122 and makes a sound, thereby being used to warn the operator.

[0053] During specific application, when the transfer rack 3 drives the goods to be hoisted and the goods become detached due to reasons such as the inclination of the transfer rack 3, in combination with Figure 12It can be known that when the detection stop 800 is applied, it also closely adheres to the goods. When the goods tend to separate, it will drive the detection stop 800 to move upward. When the detection stop 800 releases the restriction on the connecting pull rod 20 due to upward movement, the limit box 12 is affected by the elastic force of the anti-disengagement spring 16 and is forced to move in the direction of the anti-sway arm 13. During this process, when the limit box 12 moves along the anti-disengagement tooth row pull seat 10, the anti-disengagement tooth row pull seat 10 will push the one-way limit tooth row 17 upward and compress the limit top spring 170. The air flow in the limit box 12 is discharged from the pneumatic horn 122, forcing the pneumatic horn 122 to make a sound, which is used to warn the operator that the goods are offset and there may be a risk of falling off; due to the elasticity of the limit top spring 170, the moving one-way limit tooth row 17 makes an up-and-down reciprocating movement between the downward pressing of the elastic force and the upward pushing of the anti-disengagement tooth row pull seat 10, forcing the pneumatic horn 122 to make a continuous sound for alarm.

[0054] Regarding the reset of the connecting pull rod 20, when the limit box 12 is pushed by the hydraulic cylinder 5 or the anti-sway arm 13 to reset, it will eventually cause the connecting pull rod 20 to pass through the inclined surface of the detection stop 800. The connecting pull rod 20 uses the inclined surface to push the detection stop 800 upward, and after passing over the detection stop 800, it is affected by the gravity of the detection stop 800 and moves downward to lock the connecting pull rod 20 again.
