A container gate control device

Abstract

The container door control device disclosed in the application first moves the second limiting rod in each clamping mechanism to a position avoiding the unit door rotating path in a direction perpendicular to the first direction, then rotates the unit door into the gap between the corresponding first limiting rod and the second limiting rod, and then resets the second limiting rod. Repeating the above actions can restrict each unit door between the corresponding first limiting rod and the second limiting rod. Then, the corresponding clamping mechanism is driven to slide along the first direction by the driving mechanism, thereby driving any unit door to rotate, so that each unit door automatically avoids the storage unit to be loaded with the battery pack, without manually rotating the unit door, thereby reducing the manual burden and the safety risk of manual operation.

Description

Technical Field

[0001] This application relates to the field of battery packaging box equipment, specifically a container door control device. Background Technology

[0002] Energy storage systems involve stacking battery packs in various storage units within a shipping container for easy transport and management. Due to the large weight of the battery packs, automated packing equipment is typically used to load them sequentially into the various storage units within the container.

[0003] To protect the battery packs and facilitate inspection, shipping containers use multiple hinged unit doors to seal each storage unit. Therefore, these unit doors must be opened before the automated packing equipment can insert the battery packs into the container. To avoid interference with the automated packing equipment, the unit doors must open at an angle greater than 90°. However, since the storage units within the container are very close together, a unit door with an opening angle greater than 90° will partially lie in front of an adjacent storage unit, thus hindering the automated packing equipment from inserting the battery packs into the next adjacent unit.

[0004] Currently, it is common practice to assign personnel to control the door of a storage unit. Once the battery pack is installed in a storage unit, the personnel close the door of that storage unit to prevent it from affecting adjacent storage units. This results in a heavy workload for personnel and high safety risks. Summary of the Invention

[0005] To address the aforementioned technical problems, this application provides a container door control device, the specific technical solution of which is as follows:

[0006] The container door control device includes a base, multiple clamping mechanisms, and a drive mechanism, wherein:

[0007] Multiple clamping mechanisms are horizontally slidably mounted on the base along a first direction. Each clamping mechanism includes a first sliding seat, a first limiting rod, and at least one second limiting rod. The first limiting rod and at least one second limiting rod are spaced apart on the first sliding seat along the first direction. The gap between adjacent first limiting rods and second limiting rods is greater than the thickness of the unit door. Each second limiting rod can move relative to the first sliding seat in a direction perpendicular to the first direction. The driving mechanism is used to drive any of the clamping mechanisms to reciprocate along the first direction.

[0008] First, the second limiting rod in each clamping mechanism is moved along a direction perpendicular to the first direction to a position that avoids the rotation path of the unit door. Then, the unit door is rotated into the gap between the corresponding first and second limiting rods, and the second limiting rod is reset. Repeating the above actions can restrict each unit door between the corresponding first and second limiting rods. Then, the drive mechanism drives the corresponding clamping mechanism to slide along the first direction, thereby causing any unit door to rotate. This allows each unit door to automatically avoid the storage unit to be installed in the battery pack, eliminating the need for manual rotation of the unit door, reducing the workload of manual operation, and lowering the safety risks of manual operation.

[0009] In some embodiments, the clamping mechanism further includes a base plate, a locking rod, a rotating shaft, an end plate, and two side plates, wherein:

[0010] The base plate is fixed on the first sliding seat, the end plate and the two side plates are vertically fixed on the base plate, the two side plates are arranged opposite each other and are respectively located on both sides of the end plate, the rotating shaft passes through the two side plates along the first direction, the bottom of the second limiting rod is provided with a rotating body sleeved on the rotating shaft, the distance from the rotating shaft to the end plate along the direction perpendicular to the first direction is less than the length of the second limiting rod, and not less than the distance from the rotating shaft to the bottom of the rotating body;

[0011] The locking rod is embedded in one end of any of the side plates opposite to the end plate, and the locking rod is screwed onto the side plate along the first direction, or the locking rod is elastically mounted on the side plate along the first direction.

[0012] When the second limiting rod needs to be moved to a position to avoid the rotation path of the unit door, it can be rotated away from the end plate around its rotational axis, so that the second limiting rod lies flat on the first sliding seat. At this time, the unit door can be rotated between the first and second limiting rods. When the unit door needs to be restricted by the cooperation of the second and first limiting rods, the second limiting rod is rotated towards the end plate and placed against the end plate. Then, a locking rod is used to restrict the second limiting rod, preventing it from rotating away from the end plate around its rotational axis, thus restricting the unit door. By adopting the above-described installation structure for the second limiting rod, the ease of operation of the second limiting rod is improved, and the position of the second limiting rod can be easily and quickly switched manually.

[0013] In some embodiments, a limiting block is provided on the side of the second limiting rod facing the end plate, and when the second limiting rod is in a vertical state, the limiting block abuts against the end plate.

[0014] By cooperating with the end plate and locking the second limit rod with the clamp, the second limit rod can be stably kept vertical, preventing the second limit rod from rotating on its own during the sliding of the first sliding seat, which would cause the unit door to be released from restriction and improve the stability of the structure.

[0015] In some embodiments, the clamping mechanism further includes a first driving member mounted on the first sliding seat, the first driving member being used to drive all the second limit rods to move vertically up and down.

[0016] When the second limit rod needs to be moved to a position to avoid the rotation path of the unit door, the first driving component drives the second limit rod to descend vertically, making it lower than the unit door in the vertical direction. At this point, the unit door can be rotated between the first and second limit rods. When the unit door needs to be restricted by the cooperation of the second and first limit rods, the first driving component simply raises the second limit rod vertically, improving the ease of operation of the second limit rod and allowing for convenient and quick manual switching of its position.

[0017] In some embodiments, the clamping mechanism further includes at least one limiting frame fixed on the first sliding seat, and each limiting frame has a receiving cavity for a second limiting rod to be inserted vertically into the joint portion.

[0018] When the second limit rod needs to be moved to a position to avoid the rotation path of the unit door, it can be manually removed from the limit frame. At this point, the unit door can be rotated between the first and second limit rods. When the unit door needs to be restricted by the cooperation of the second and first limit rods, the second limit rod can be inserted back into the limit frame. This improves the ease of operation of the second limit rod, allowing for quick and easy manual switching of its position.

[0019] In some embodiments, both the first limiting rod and the second limiting rod are fitted with a roller sleeve that can rotate vertically.

[0020] When the unit door is driven to rotate by the first or second limit rod, the roller sleeve replaces the first or second limit rod to contact the unit door. The roller sleeve reduces the friction between itself and the unit door by rotating, which reduces the load on the drive mechanism and lowers the equipment cost.

[0021] In some embodiments, the driving mechanism includes a second sliding seat, a first pin, a second driving member, and a driving assembly; the clamping mechanism further includes a first socket mounted on the first sliding seat, wherein:

[0022] The driving component is used to drive the second sliding seat to slide back and forth along the first direction. The first pin and the second driving member are disposed on the second sliding seat. The second driving member is used to drive the first pin to be inserted into the first socket of any of the clamping mechanisms.

[0023] When the drive mechanism needs to move the clamping mechanism, the drive component first moves the second sliding seat to the clamping mechanism, and the second drive component inserts the first pin into the first socket of the clamping mechanism, so that the first sliding seat and the second sliding seat are relatively fixed. The drive component can then drive the clamping mechanism to slide along the first direction to the predetermined position. A single drive mechanism can drive any clamping mechanism to slide along the first direction, which reduces equipment costs and does not affect the production cycle.

[0024] In some embodiments, the drive assembly includes a timing belt, a third drive member, a timing pulley, and two idler pulleys. The timing belt is fixed to the base extending along the first direction. The timing pulley abuts against the lower surface of the timing belt. The two idler pulleys abut against the upper surface of the timing belt and are respectively located on both sides of the timing pulley along the first direction. The lower surface of the timing belt is toothed and meshes with the timing pulley. The third drive member is used to drive the timing pulley to rotate.

[0025] The timing belt is clamped by placing two idler pulleys and a timing pulley in a triangular symmetrical arrangement. Through the meshing of the teeth of the timing pulley and the timing belt, the timing pulley rotates relative to the timing belt when the third driving component drives the timing pulley to rotate, thus realizing the horizontal sliding of the second sliding seat in the first direction.

[0026] In some embodiments, the drive assembly includes a timing belt, a fourth drive member, a driven wheel, and a drive wheel. The driven wheel and the drive wheel are rotatably disposed at both ends of the base along the first direction. The timing belt is sleeved on the driven wheel and the drive wheel. The fourth drive member is used to drive the timing belt to rotate cyclically along the first direction. The second sliding seat is fixedly connected to the timing belt.

[0027] By fixing the second sliding seat and the timing belt together, when the fourth driving member drives the timing belt to slide along the first direction, the second sliding seat can be driven to slide horizontally along the first direction.

[0028] In some embodiments, the container door control device further includes a plurality of second sockets mounted on the base, and the clamping mechanism further includes a second pin and a fifth driving member mounted on the first sliding seat, the fifth driving member being used to drive the second pin to insert into the corresponding second socket.

[0029] After any unit door is rotated to a predetermined position by the cooperation of the clamping mechanism and the drive mechanism, the fifth drive member extends the second pin vertically downward, thereby inserting the second pin into the second socket below. The unit door and the clamping mechanism are then fixed in the predetermined position, preventing the clamping mechanism from sliding along the first direction and causing the unit door to shake. This achieves self-locking of the unit door in the predetermined position and improves the stability of equipment operation. Attached Figure Description

Detailed Implementation

[0038] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] like Figure 1 and Figure 2 As shown, a container door control device includes a base 1, multiple clamping mechanisms 2, and a drive mechanism 4, wherein:

[0040] Multiple clamping mechanisms 2 are horizontally slidably mounted on a slide rail of the base 1 along the first direction X via sliders. Each clamping mechanism 2 includes a first sliding seat 21, a first limiting rod 22, and at least one second limiting rod 23. The first limiting rod 22 and at least one second limiting rod 23 are spaced apart on the first sliding seat 21 along the first direction X. The gap between adjacent first limiting rods 22 and second limiting rods 23 is greater than the thickness of the unit door 5. Each second limiting rod 23 can move relative to the first sliding seat 21 in a direction perpendicular to the first direction X. The driving mechanism 4 is used to drive any clamping mechanism 2 to reciprocate along the first direction X.

[0041] First, the second limiting rod 23 in each clamping mechanism 2 is moved along a direction perpendicular to the first direction X to a position that avoids the rotation path of the unit door 5. Then, the unit door 5 is rotated into the gap between the corresponding first limiting rod 22 and second limiting rod 23, and then the second limiting rod 23 is reset. By repeating the above actions, each unit door 5 can be restricted between the corresponding first limiting rod 22 and second limiting rod 23. Then, the driving mechanism 4 drives the corresponding clamping mechanism 2 to slide along the first direction X, thereby driving any unit door 5 to rotate, so that each unit door 5 automatically avoids the storage unit 6 to be installed in the battery pack. There is no need to manually rotate the unit door 5, which reduces the manual burden and also reduces the safety risks of manual operation.

[0042] In some embodiments, such as Figure 3 and Figure 4 As shown, the clamping mechanism 2 also includes a base plate 24, a locking rod 25, a rotating shaft 26, an end plate 27, and two side plates 28. The base plate 24 is fixed on the first sliding seat 21. The end plate 27 and the two side plates 28 are vertically fixed on the base plate 24. The two side plates 28 are arranged opposite each other and are located on both sides of the end plate 27. The rotating shaft 26 passes through the two side plates 28 along the first direction X. The bottom of the second limiting rod 23 has a rotating body 32 that is sleeved on the rotating shaft 26. The distance from the rotating shaft 26 to the end plate 27 along the direction perpendicular to the first direction X is less than the length of the second limiting rod 23 and not less than the distance from the rotating shaft 26 to the bottom of the rotating body 32.

[0043] like Figure 3 and Figure 4 As shown, the locking rod 25 is embedded at one end of the side plate 28 away from the end plate 27. The locking rod 25 is screwed onto the side plate 28 along the first direction X, or the locking rod 25 is elastically mounted on the side plate 28 along the first direction X by a spring.

[0044] When the second limiting rod 23 needs to be moved to a position that avoids the rotation path of the unit door 5, it can be rotated around the pivot 26 in a direction away from the end plate 27, so that the second limiting rod 23 lies flat on the first sliding seat 21. At this time, the unit door 5 can be rotated between the first limiting rod 22 and the second limiting rod 23. When it is necessary to restrict the unit door 5 by cooperating with the second limiting rod 23 and the first limiting rod 22, the second limiting rod 23 is rotated towards the end plate 27 and placed against the end plate 27. Then, the locking rod 25 is used to restrict the second limiting rod 23, preventing it from rotating around the pivot 26 in a direction away from the end plate 27, thus restricting the unit door 5. By adopting the above-described installation structure of the second limiting rod 23, the ease of operation of the second limiting rod 23 is improved, and the position of the second limiting rod 23 can be switched easily and quickly by personnel.

[0045] In some embodiments, such as Figure 3 and Figure 4 As shown, a limiting block 29 is provided on the side of the second limiting rod 23 facing the end plate 27. When the second limiting rod 23 is in a vertical state, the limiting block 29 abuts against the end plate 27. Through the cooperation between the limiting block 29 and the end plate 27, and with the locking of the second limiting rod 23 by the locking rod 25, the second limiting rod 23 can be stably kept in a vertical state, preventing the second limiting rod 23 from rotating on its own during the sliding of the first sliding seat 21, which would cause the unit door 5 to be released from restriction, thus improving the stability of the structure.

[0046] In some embodiments, such as Figure 1 As shown, when the clamping mechanism 2 only needs to clamp one unit door 5, the number of second limiting rods 23 is only one. One first limiting rod 22 and one second limiting rod 23 work together to restrict the unit door 5.

[0047] In some embodiments, such as Figure 2 As shown, when the clamping mechanism 2 needs to clamp two unit doors 5, there are two second limiting rods 23. The two second limiting rods 23 are located on both sides of the first limiting rod 22. The clamping mechanism 2 is moved between the two adjacent unit doors 5 on the hinge side, and both second limiting rods 23 are rotated to a horizontal state to avoid the rotation path of the unit doors 5. Then, the two unit doors 5 can be rotated between the corresponding second limiting rod 23 and the first limiting rod 22. The two second limiting rods 23 are then reset, and the unit doors are presented with the desired position. Figure 2 The state shown.

[0048] It should be noted that when the clamping mechanism 2 needs to clamp two unit doors 5, the positional relationship between the first limiting rod 22 and the two second limiting rods 23 on the clamping mechanism 2 can be arranged in several ways. The first limiting rod 22 can be located on the far left, with the two second limiting rods 23 arranged sequentially to the right of the first limiting rod 22; alternatively, the first limiting rod 22 can be located on the far right, with the two second limiting rods 23 arranged sequentially to the left of the first limiting rod 22. The key is to achieve separate restriction of the two unit doors 5.

[0049] In some embodiments, the clamping mechanism 2 further includes a first driving member, which is mounted on a first sliding seat 21. The first driving member is used to drive all the second limit rods 23 to move vertically up and down. The first driving member can be a cylinder. When it is necessary to move the second limit rod 23 to a position that avoids the rotation path of the unit door 5, the first driving member drives the second limit rod 23 to descend vertically, so that the second limit rod 23 is lower than the unit door 5 in the vertical direction. At this time, the unit door 5 can be rotated between the first limit rod 22 and the second limit rod 23. When it is necessary to restrict the unit door 5 by cooperating with the second limit rod 23 and the first limit rod 22, the first driving member then raises the second limit rod 23 vertically, which improves the ease of operation of the second limit rod 23, and allows for convenient and quick manual switching of the position of the second limit rod 23.

[0050] In some embodiments, the clamping mechanism 2 further includes at least one limiting frame fixed on the first sliding seat 21, each limiting frame having a receiving cavity for a second limiting rod 23 to be vertically inserted and partially joined. When it is necessary to move the second limiting rod 23 to a position to avoid the rotation path of the unit door 5, the second limiting rod 23 can be manually removed from the limiting frame, at which point the unit door 5 can be rotated between the first limiting rod 22 and the second limiting rod 23. When it is necessary to restrict the unit door 5 by cooperating with the second limiting rod 23 and the first limiting rod 22, the second limiting rod 23 can be inserted back into the limiting frame, improving the ease of operation of the second limiting rod 23, allowing for convenient and quick manual switching of the position of the second limiting rod 23.

[0051] In some embodiments, such as Figure 4 As shown, both the first limiting rod 22 and the second limiting rod 23 are fitted with roller sleeves 30 that can rotate vertically. When the unit door 5 is pushed to rotate by the first limiting rod 22 or the second limiting rod 23, the roller sleeve 30 replaces the first limiting rod 22 or the second limiting rod 23 to contact the unit door 5. The roller sleeve 30 reduces the friction between itself and the unit door 5 by rotating, which reduces the load on the drive mechanism 4 and lowers the equipment cost.

[0052] In some embodiments, such as Figure 5As shown, the drive mechanism 4 includes a second sliding seat 41, a first pin 42, a second drive member 43, and a drive assembly. The clamping mechanism 2 also includes a first socket 31 mounted on the first sliding seat 21 (see...). Figure 3 The second sliding seat 41 is also slidably mounted on a slide rail of the base 1 via a slider. The slide rails containing the first sliding seat 21 and the second sliding seat 41 are arranged parallel to each other. The driving component is used to drive the second sliding seat 41 to reciprocate along the first direction X. The first pin 42 and the second driving member 43 are disposed on the second sliding seat 41. The second driving member 43 is used to drive the first pin 42 to insert into the first socket 31 of any clamping mechanism 2. The second driving member 43 can be a cylinder.

[0053] When the drive mechanism 4 needs to move the clamping mechanism 2, the drive assembly first moves the second sliding seat 41 to the clamping mechanism 2, and the second drive member 43 inserts the first pin 42 into the first socket 31 of the clamping mechanism 2, so that the first sliding seat 21 and the second sliding seat 41 are relatively fixed. The drive assembly can then drive the clamping mechanism 2 to slide along the first direction X to the predetermined position. A single drive mechanism 4 can drive any clamping mechanism 2 to slide along the first direction X, which reduces equipment costs and does not affect the production cycle.

[0054] In some embodiments, such as Figure 5 As shown, the drive assembly includes a synchronous belt 44, a third drive member 45, a synchronous pulley 46, and two idler pulleys 47. The synchronous belt 44 is fixed to the base 1 extending along a first direction X. The synchronous pulley 46 rests against the lower surface of the synchronous belt 44, and the two idler pulleys 47 rest against the upper surface of the synchronous belt 44. The two idler pulleys 47 are located on opposite sides of the synchronous pulley 46 along the first direction X. The lower surface of the synchronous belt 44 is toothed and meshes with the synchronous pulley 46. The third drive member 45 drives the synchronous pulley 46 to rotate. The synchronous belt 44 can be a toothed belt or a V-belt, and the third drive member 45 can be a servo motor.

[0055] The timing belt 44 is clamped by placing two idler pulleys 47 and timing pulley 46 in a triangular symmetrical arrangement. When the teeth of timing pulley 46 and timing belt 44 mesh, the timing pulley 46 rotates relative to timing belt 44 when the third drive member 45 drives the timing pulley 46 to rotate, thereby realizing the horizontal sliding of the second sliding seat 41 in the first direction X.

[0056] In some embodiments, the drive assembly includes a timing belt 44, a fourth drive member, a driven pulley, and a drive pulley. The driven pulley and drive pulley are rotatably disposed at both ends of the base 1 along the first direction X. The timing belt 44 is fitted onto the driven pulley and drive pulley. The fourth drive member drives the timing belt 44 to rotate cyclically along the first direction X. The second sliding seat 41 is fixedly connected to the timing belt 44. The fourth drive member can be a servo motor. By fixing the second sliding seat 41 and the timing belt 44 together, when the fourth drive member drives the timing belt 44 to slide along the first direction X, it can also drive the second sliding seat 41 to slide horizontally along the first direction X.

[0057] In some embodiments, such as Figure 6 As shown, the container door control device also includes multiple second sockets 11 mounted on the base 1, and the clamping mechanism 2 also includes second pins 12 mounted on the first sliding seat 21 and a fifth driving member 13. The fifth driving member 13 is used to drive the second pins 12 to insert into the corresponding second sockets 11. The fifth driving member 13 can be a cylinder.

[0058] After any unit door 5 is rotated to a predetermined position by the cooperation of the clamping mechanism 2 and the drive mechanism 4, the fifth drive member 13 extends the second pin 12 vertically downward, so that the second pin 12 is inserted into the second socket 11 below. The unit door 5 and the clamping mechanism 2 are then fixed in the predetermined position, preventing the clamping mechanism 2 from sliding along the first direction X and causing the unit door 5 to shake on its own. This achieves self-locking of the unit door 5 in the predetermined position and improves the stability of the equipment operation.

[0059] In summary, such as Figure 1 As shown, the number of clamping mechanisms 2 in the container door control device of this application depends on the actual situation of the container. If there are 6 unit doors 5 on the container, and the hinge sides of every two unit doors 5 in the middle 4 unit doors 5 are adjacent, then the container door control device needs a total of 4 clamping mechanisms 2 arranged in sequence along the first direction X. The two clamping mechanisms 2 in the middle have a first limiting rod 22 and two second limiting rods 23 respectively. The two clamping mechanisms 2 in the middle restrict two unit doors 5 respectively. The other two clamping mechanisms 2 only need one first limiting rod 22 and one second limiting rod 23, and only need to restrict one unit door 5 respectively.

[0060] The actual working process of the container door control device described above is as follows: After the container is transported to the vicinity of the container door control device, the second limit rods 23 on each clamping mechanism 2 are first switched to positions that avoid the rotation path of the unit door 5. Then, each unit door 5 is rotated between the corresponding first limit rod 22 and second limit rod 23. Subsequently, the second limit rod 23 is reset, so that each unit door 5 is restricted by the corresponding first limit rod 22 and second limit rod 23. Then, the drive mechanism 4 slides to the unit door 5 that needs to be rotated and inserts the first pin 42 into the first socket 31. The fifth drive member 13 on the clamping mechanism 2 corresponding to the unit door 5 disengages the second pin 12 from the second socket 11 at this location. At this time, the drive mechanism 4 can drive the clamping mechanism 2 to slide to the predetermined position. After the clamping mechanism 2 reaches the predetermined position, the fifth drive member 13 inserts the second pin 12 into the second socket 11 at the predetermined position, and the clamping mechanism 2 is locked in the predetermined position, completing the automatic rotation action of the unit door 5.
