Description

Technical Field

[0001] The present invention relates to the technical field of precision detection, and in particular to a precision detection device and method for a fully automatic twist lock for a container. Background Art

[0002] The main function of the fully automatic twist lock of the container is to ensure the stability and safety of the container during transportation. ‌ Working principle of the fully automatic twist lock The fully automatic twist lock realizes automatic locking and unlocking through the action of gravity. One end of it is spiral-shaped. When the container is pressed on the twist lock by gravity, the spiral lock head will generate a torque to rotate the lock head and lock the container. When the gravity is withdrawn, the lock head will swing back under the action of the spring to unlock the container. During the container transportation process, the fully automatic twist lock can fix the container on the ship or trailer to ensure that the container will not move or fall off during transportation. Advantages and disadvantages of fully automatic twist locks ‌Advantages‌: ‌High degree of automation‌: No manual operation is required, reducing labor costs. High safety‌: Automatic locking by gravity reduces the possibility of human operating errors. ‌Strong applicability‌: Suitable for various transportation scenarios, especially in logistics environments with a high degree of automation.

[0003] After the full-automatic twist lock is processed, it needs to be placed on a test seat simulating a container seat. By applying test forces in the upward, downward and sideways directions, observe whether the full-automatic twist lock is detached from the test seat, so as to judge whether the full-automatic twist lock is qualified. The accuracy of this test method is low. Since the thickness of the pad affects the size of the gap between the pad and the test seat, when the gap is large, the connection gap between the container and the full-automatic twist lock is large, and it is easy to tilt. When the gap between the pad and the test seat is small, it is easy to cause the container and the full-automatic twist lock to fail to engage. As long as the gap reaches a certain appropriate height, the full-automatic twist lock and the container can be fully engaged and locked, and the engagement is firm and not prone to shaking. At present, the detection accuracy of the full-automatic twist lock is low during the test process, and the thickness of the pad cannot be detected. It is also inconvenient to distinguish between qualified and unqualified products, which easily causes repeated detection and reduces the efficiency of detection. Summary of the invention

[0015] A detection method for a precision detection device of a fully automatic twist lock for a container comprises the following specific steps:

[0016] Step 1: assembling the lock body. Place one end of the fully automatic twist lock body on the lower seat body. Then adjust the working height of the upper seat body fixed below the strip plate through the lifting assembly installed on the top plate, so that the upper seat body moves downward to contact the upper end of the fully automatic twist lock body. The upper end of the fully automatic twist lock body is rotated under force, so as to achieve the purpose of being engaged in the upper seat body, so that the fully automatic twist lock body is assembled with the lower seat body and the upper seat body.

[0017] Step 2: lock body thickness detection. When the upper seat moves downward, the thickness detection rod arranged in the rectangular slot moves synchronously. The thickness of the pad of the full-automatic twist lock body is detected by the height of the thickness detection rod in contact with the pad. If the pad thickness is qualified, one end of the first contact rod connected to the thickness detection rod can be abutted against the marking component, which is convenient for qualified marking processing.

[0018] Step three, lateral force application and automatic marking, the push plate is driven to move by the second electric push rod, so that the push plate is pressed against the pad of the full-automatic twist lock body, and lateral force is applied. At the same time, the interference strip fixed on the push plate is pressed against the rectangular sheet, so that the rectangular sheet drives the first interference frame to move, so that it can automatically contact the first interference rod. When the first interference rod is subjected to force, it can contact the marking component, so that the marking component is moved downward to mark the pad of the qualified full-automatic twist lock body. If the pad thickness test fails, the marking component cannot be moved downward for marking. After marking, the rectangular sheet drives the strip rod, the slide rod, and the guide block to work together, so that the marking component is offset.

[0019] Step 4: Lock body detachment test: After applying force to the side of the fully automatic twist lock body, the lifting assembly retracts, and a pulling force is applied to the upper seat body fixed under the strip plate to observe whether the fully automatic twist lock body detaches from the upper seat body or the lower seat body. If it does not detach, it means that the fully automatic twist lock body is qualified, and if it detaches, it means that the fully automatic twist lock body is unqualified.

[0020] Step 5. The lock body is detached from the mark. When the fully automatic twist lock body is detached, the displacement detection rod can slide in the round hole on the strip plate. During the sliding process, the displacement detection rod collides with the second interference frame in the L-shaped groove, prompting the second interference frame to drive the third interference block to move horizontally and collide with the second interference wedge block, so that the second interference rod moves downward, thereby pushing the marking assembly to move downward, and marking the fully automatic twist lock body that fails to detach.

[0021] The present invention has the following beneficial effects:

[0022] 1. In the precision detection device for the fully automatic twist lock for containers, the lower end of the fully automatic twist lock body is conveniently installed by the lower seat body, and the working height of the upper seat body can be adjusted by the lifting assembly installed on the top plate, which can drive the upper seat body to move down and engage with the upper end of the fully automatic twist lock body to assemble the fully automatic twist lock body. During the engagement process, the thickness of the pad of the fully automatic twist lock body can be detected by the thickness detection rod set in the rectangular notch. If the pad thickness is qualified, the fully automatic twist lock body is fixed with the upper seat body and the lower seat body, and it is not easy to shake. At the same time, the thickness detection rod When sliding a certain distance within the upper seat body, one end of the first resistance rod connected to the thickness detection rod can be located on one side of the marking component to generate heat. When the first resistance rod is moved by force, the marking rod in the marking component is prompted to slide downward indirectly, so that the marking rod can leave a qualified mark on the surface of the pad on the full-automatic twist lock body. If the thickness of the pad is unqualified, the thickness detection rod cannot drive the first resistance rod to resist the marking component. In this case, marking cannot be performed when the thickness of the pad is unqualified. Through the cooperation of the thickness detection rod and the marking component, the efficiency and accuracy of detection can be greatly improved, which saves time and effort, is convenient and quick, and is convenient for distinguishing qualified products from unqualified products.

[0023] 2. In the precision detection device for the fully automatic twist lock for containers, the horizontal position of the push plate fixed on the end can be adjusted by the second electric push rod, and it can be pressed against the pad when moving, so that the force applied by the second electric push rod can act on the fully automatic twist lock body. At the same time, the lifting component adjusts the height of the strip plate, and can apply an upward force to the upper seat body, so that it can be observed whether the fully automatic twist lock body is detached from the upper seat body or the lower seat body, so as to detect the connection firmness of the fully automatic twist lock body. At the same time, the push plate can drive the resistance strip and the rectangular sheet to move forward during the movement. The purpose of the interference is to cause the first interference frame to interfere with the first interference rod, so that one end of the first interference rod is affected by the interference force and moves horizontally to interfere with the first interference wedge in the marking component, so that the marking rod can automatically mark the pad with qualified thickness. At the same time, after the marking is completed, the strip rod can push the guide block in the marking component to slide on the slide rod, so that the working position of the marking rod can be adjusted, so that the marking rod can be reused, and qualified marks and unqualified marks can be marked on the pad, which is convenient for personnel to distinguish products.

[0024] 3. In the precision detection device for the fully automatic twist lock for containers, a circular hole arranged on the strip plate can be slidably connected with the displacement detection rod fixed on the top plate. If the upper seat body applies an upward force to cause the fully automatic twist lock body to be detached, the displacement detection rod can slide relatively in the circular hole, so that the displacement detection rod and the second interference frame can be colliding with each other, and the second interference frame can be prompted to drive the third interference block to move horizontally to interfere with the second interference wedge block, so that the second interference wedge block is affected by the interference force and drives the second interference rod to move vertically downward on the upper seat body, so that the lower end of the second interference rod can interfere with the upper end of the first interference wedge block, so that the marking rod can automatically move downward to perform marking processing on one side of the pad. If the fully automatic twist lock body is not detached, the pad will not be marked for the second time, which can improve the efficiency and quality of the full-automatic twist lock body detection.

[0036] A first abutting rod 13 is slidably connected to the thickness detecting rod 10 , and a second spring 14 is connected between the first abutting rod 13 and the thickness detecting rod 10 .

[0037] The marking assembly includes a guide block 91, which is arranged in the rectangular slot 9. A marking rod 92 is slidably connected to the guide block 91. A first interference wedge 93 is fixed to the upper end of the marking rod 92, and the marking rod 92 is slidably connected to the upper seat 5. The guide block 91 is elastically connected to the first interference wedge 93 through a third spring 94. The first interference wedge 93 is located on one side of the first interference rod 13.

[0038] The lifting assembly includes a first electric push rod 71, which is fixed on the top plate 4, and L-shaped connecting blocks 72 are fixed on both sides of the strip plate 7.

[0044] When the thickness test of the backing plate 8 of the full-automatic twist lock body 6 is passed, the anti-slip performance of the full-automatic twist lock body 6 needs to be tested. Figure 1-Figure 4 , the push plate 17 is driven to move by the second electric push rod 16, so that the push plate 17 is pressed against the pad 8 of the full-automatic twist lock body 6, and a side force is applied. At the same time, the fixed resistance strip 21 on the push plate 17 is pressed against the rectangular sheet 19, and the fourth spring 20 is charged. The rectangular sheet 19 drives the first resistance frame 18 to be pressed against the first resistance rod 13, so that the first resistance rod 13 is moved horizontally and automatically pressed against the first resistance wedge 93, so that the purpose of automatically marking the full-automatic twist lock body 6 that has passed the thickness detection can be achieved. Then the first electric push rod 71 is retracted, and the A certain upward pulling force is applied to the upper seat body 5 fixed under the strip plate 7, and the full-automatic twist lock body 6 is observed to see whether it is separated from the upper seat body 5 or the lower seat body 2 under a certain pulling force.

[0045] Embodiment 3: This embodiment is an improvement made on the basis of Embodiment 1. For details, please refer to Figures 1 to 7A circular hole 25 is opened on the strip plate 7, and a displacement detection rod 26 is slidably connected in the circular hole 25. One end of the displacement detection rod 26 is fixed on the top plate 4, and a sixth spring 261 is connected between the displacement detection rod 26 and the strip plate 7.

[0046] An L-shaped slot 27 is provided on the strip plate 7, and a second interference rod 28 is provided in the L-shaped slot 27. The upper end of the second interference rod 28 is slidably connected to the strip plate 7, and the lower end of the second interference rod 28 is slidably connected to the support bar 11. A seventh spring 33 is connected between the second interference rod 28 and the strip plate 7, and the seventh spring 33 is located in the L-shaped slot 27.

A second interference frame 31 is provided in the L-shaped slot 27, and the second interference frame 31 is elastically connected to the strip plate 7 through an eighth spring 32. One end of the second interference frame 31 is located in the circular hole 25, and a third interference block 30 is fixed to the other end of the second interference frame 31, and the third interference block 30 interferes with the second interference wedge 29.

[0047] In order to conveniently distinguish whether the lock body is qualified in the disengagement test, it is necessary to mark the unqualified fully-automatic twist lock body 6. If the fully-automatic twist lock body 6 is unqualified, the relative sliding distance of the displacement detection rod 26 in the circular hole 25 on the strip plate 7 is large, which can achieve the purpose of the displacement detection rod 26 and the second interference frame 31 in the L-shaped groove 27. The second interference frame 31 drives the third interference block 30 to move horizontally, and the eighth spring 32 accumulates force. The third interference block 30 moves horizontally and can interfere with the second interference wedge 29, so that the second interference wedge 29 drives the second interference rod 28 to move downward, and the seventh spring 33 accumulates force. The second interference rod 28 moving downward can achieve the purpose of interfering with the first interference wedge 93, so that the first interference wedge 93 drives the marking rod 92 to move downward when affected by the interference force, and the unqualified fully-automatic twist lock body 6 is marked. The position of the mark is located on one side of the first mark. The positions of the two marks are different, which is convenient for distinction.

[0048] Embodiment 4: This embodiment is an improvement made on the basis of Embodiments 1, 2 and 3. For details, please refer to Figures 1 to 7 , a detection method for a precision detection device of a fully automatic twist lock for a container, comprising the following specific steps:

[0049] Step 1: assembling the lock body. Place one end of the fully automatic twist lock body 6 on the lower seat body 2. Then adjust the working height of the upper seat body 5 fixed below the strip plate 7 by the lifting assembly installed on the top plate 4, so that the upper seat body 5 moves downward to contact the upper end of the fully automatic twist lock body 6. The upper end of the fully automatic twist lock body 6 is rotated by force, so as to achieve the purpose of engaging in the upper seat body 5, so that the fully automatic twist lock body 6 is assembled with the lower seat body 2 and the upper seat body 5.

[0050] Step 2: lock body thickness detection. When the upper seat 5 moves downward, the thickness detection rod 10 arranged in the rectangular notch 9 moves synchronously. The thickness of the backing plate 8 of the full-automatic twist lock body 6 is detected by the height of the thickness detection rod 10 in contact with the backing plate 8. If the backing plate 8 is qualified in the thickness detection, one end of the first abutting rod 13 connected to the thickness detection rod 10 can be abutted against the marking component, which is convenient for qualified marking processing.

[0051] Step 3, lateral force application and automatic marking, the push plate 17 is driven to move by the second electric push rod 16, so that the push plate 17 is pressed against the pad 8 of the full-automatic twist lock body 6, and lateral force is applied. At the same time, the fixed resistance strip 21 on the push plate 17 is pressed against the rectangular sheet 19, so that the rectangular sheet 19 drives the first resistance frame 18 to move, so that it can automatically press against the first resistance rod 13. When the first resistance rod 13 is subjected to force, it can press against the marking component, so that the marking component is moved downward to mark the pad 8 of the qualified full-automatic twist lock body 6. If the thickness of the pad 8 is unqualified, the marking component cannot be moved downward for marking. After marking, the rectangular sheet 19 drives the strip rod 24 to be linked with the slide rod 22 and the guide block 91, so that the marking component is offset.

[0052] Step 4: Lock body detachment detection: After applying force to the side of the full-automatic twist lock body 6, the lifting assembly retracts, and an upward force is applied to the upper seat body 5 fixed below the strip plate 7 to observe whether the full-automatic twist lock body 6 is detached from the upper seat body 5 or the lower seat body 2. If it is not detached, it means that the full-automatic twist lock body 6 is qualified, and if it is detached, it means that the full-automatic twist lock body 6 is unqualified;

[0053] Step 5, the lock body is detached from the mark. When the fully automatic twist lock body 6 is detached, the displacement detection rod 26 can slide relatively in the circular hole 25 on the strip plate 7. During the sliding process, the displacement detection rod 26 conflicts with the second interference frame 31 in the L-shaped groove 27, prompting the second interference frame 31 to drive the third interference block 30 to move horizontally and conflict with the second interference wedge block 29, so that the second interference rod 28 moves downward, thereby pushing the marking assembly to move downward, and marking the fully automatic twist lock body 6 that fails to detach.

5. The detection method of the precision detection device of the fully automatic twist lock for container according to claim 4, characterized in that: The specific steps include: Step 1: assembling the lock body. Place one end of the fully automatic twist lock body on the lower seat body. Then adjust the working height of the upper seat body fixed below the strip plate through the lifting assembly installed on the top plate, so that the upper seat body moves downward to contact the upper end of the fully automatic twist lock body. The upper end of the fully automatic twist lock body is rotated under force, so as to achieve the purpose of being engaged in the upper seat body, so that the fully automatic twist lock body is assembled with the lower seat body and the upper seat body. Step 2: lock body thickness detection. When the upper seat moves downward, the thickness detection rod arranged in the rectangular slot moves synchronously. The thickness of the pad of the full-automatic twist lock body is detected by the height of the thickness detection rod in contact with the pad. If the pad thickness is qualified, one end of the first contact rod connected to the thickness detection rod can be abutted against the marking component, which is convenient for qualified marking processing. Step three, lateral force application and automatic marking, the push plate is driven to move by the second electric push rod, so that the push plate is pressed against the pad of the full-automatic twist lock body, and lateral force is applied. At the same time, the interference strip fixed on the push plate is pressed against the rectangular sheet, so that the rectangular sheet drives the first interference frame to move, so that it can automatically contact the first interference rod. When the first interference rod is subjected to force, it can contact the marking component, so that the marking component is moved downward to mark the pad of the qualified full-automatic twist lock body. If the pad thickness test fails, the marking component cannot be moved downward for marking. After marking, the rectangular sheet drives the strip rod, the slide rod, and the guide block to work together, so that the marking component is offset. Step 4: Lock body detachment test: After applying force to the side of the fully automatic twist lock body, the lifting assembly retracts, and a pulling force is applied to the upper seat body fixed under the strip plate to observe whether the fully automatic twist lock body detaches from the upper seat body or the lower seat body. If it does not detach, it means that the fully automatic twist lock body is qualified, and if it detaches, it means that the fully automatic twist lock body is unqualified. Step 5. The lock body is detached from the mark. When the fully automatic twist lock body is detached, the displacement detection rod can slide in the round hole on the strip plate. During the sliding process, the displacement detection rod collides with the second interference frame in the L-shaped groove, prompting the second interference frame to drive the third interference block to move horizontally and collide with the second interference wedge block, so that the second interference rod moves downward, thereby pushing the marking assembly to move downward, and marking the fully automatic twist lock body that fails to detach.
