Description

Technical Field

[0001] The invention relates to the field of container construction, and more particularly to a container stacking calibrator. Background Art

[0002] Container buildings are usually simple houses built with containers as the main structure. Most of them are loaded on vehicles and placed in mobile places. They are widely used for their convenient assembly and disassembly and low cost. Since it takes time to align the upper and lower positions of container buildings when stacking, fine-tuning is required after stacking, which prolongs the stacking time and affects the stacking efficiency, thus increasing labor costs.

[0003] In order to solve the above problems, a Chinese patent with authorization announcement number CN206487162U discloses a container stacking calibrator. The application has a simple structure and effectively ensures the stacking efficiency and stacking accuracy of the top stacked containers. However, when actually stacking the container buildings, four sets of lifting ropes are mainly led out at the moving end of the crane, and then the lifting ropes are effectively fixed to the connecting parts at the four corners of the top of the container-type building. The crane is used for moving and stacking. The hoisted container building will swing due to the speed of the crane movement and the wind force in the environment. It cannot fall quickly between the two second right-angle pressure plates when swinging. Although the stacking accuracy can be effectively improved, the stacking efficiency and rate are limited.

When the container falls, it will first contact the tops of the two contact rods, pushing the contact rods to drive the second ratchet bar to move downward, and the beveled edges of the teeth of the second ratchet bar slide with the beveled edges of the teeth of the first ratchet bar, which can ensure that the second ratchet bar and the second movable plate cannot move upward, thereby ensuring the fit between the splint and the container, effectively improving the stability of the calibrator.

[0019] 3. This solution is provided with a recovery component. As the container building continues to fall, it will continue to squeeze the contact rod downward. When the contact rod moves to the through slot, the second spring in a stretched state contracts rapidly, pulling the contact rod to move into the through slot, so that the contact rod is quickly moved away from the bottom of the container building. This design realizes the automatic recovery of the contact rod when the containers are stacked through the elastic retraction characteristics of the second spring, eliminating the need for manual intervention and greatly improving convenience.

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0023] See also Figures 1 to 9 A container stacking calibrator includes a corner plate 1, two corner plates 1 are provided, quick locking components 2 for quickly fixing the two corner plates 1 are provided on both sides of the corner plate 1, and an anti-skid component 5 for preventing the calibrator from sliding down is provided in the middle of one edge of the corner plate 1.

[0024] like Figure 2 and Figure 3 As shown, the quick locking assembly 2 includes a fixed block 26 fixed at the middle of both sides of the angle plate 1 near the bottom, an L-shaped plate 21 sliding at the corner of the angle plate 1, a connecting hollow block 29 fixed at the edges of both sides of the angle plate 1 near the bottom, and two clamping blocks 27 fixed at the edges of both sides of the other angle plate 1, the L-shaped plate 21 is hinged with hinged rods 22 on both sides, the fixed block 26 is internally slidably connected with a first telescopic rod 23, one side of the first telescopic rod 23 is fixedly connected with a pushing block 24, one side of the pushing block 24 is provided with two inclined surfaces, a C-shaped block 25 is slidably connected to the top and bottom of the hollow block 29, a first spring 28 is arranged between the two C-shaped blocks 25, and a limiting assembly 3 for limiting alignment is arranged in the middle of both sides of the angle plate 1.

[0025] The connecting hollow block 29 is located between the two clamping blocks 27. The connecting hollow block 29 and the clamping block 27 are arranged in directions perpendicular to each other. The opening of the C-shaped block 25 is arranged back to back. The C-shaped block 25 and the clamping block 27 are adapted to each other. The pushing block 24 is located inside the connecting hollow block 29 and slides with each other. The two inclined surfaces of the pushing block 24 are respectively in contact with the two C-shaped blocks 25. A locking bolt is threadedly connected to the middle of one side of the L-shaped plate 21.

[0026] When the calibrator is used, it needs to be enclosed outside the container building, and the two corner plates 1 need to be effectively fixed at the place where they are connected. Since the place where the two corner plates 1 are connected is at the diagonal position, after fixing one position, it is necessary to fix the other position. Not only does it need to be completed twice, but the two corner plates 1 cannot be relatively stable, which increases the difficulty of fixing. To this end, the two angle panels 1 are enclosed around the periphery of the container building, and the two angle panels 1 are aligned with each other, and the connecting hollow block 29 on one angle panel 1 is aligned with the two clamping blocks 27 on the other angle panel 1 and inserted. At this time, the connecting hollow block 29 is tightly fitted with the clamping block 27, and the sliding adjustment of the first telescopic rod 23 drives the inclined surface of the pushing block 24 to contact the C-shaped block 25, and the two C-shaped blocks 25 are squeezed out of the inside of the connecting hollow block 29 and tightly sleeved on the outside of the clamping block 27 to achieve stable fixation, reduce the number of operating steps, and improve calibration efficiency. The limiting effect of the first spring 28 ensures that the C-shaped block 25 is always retracted during installation and disassembly. The interior of the connecting hollow block 29 prevents the C-shaped block 25 below from extending out of the connecting hollow block 29 due to gravity, causing the connecting hollow block 29 to be unable to be inserted and removed between the two blocks 27, further optimizing the stability of the calibrator. The movement of the first telescopic rod 23 drives the L-shaped plate 21 to move downward through the hinge rod 22, and then transmits through another hinge rod 22 to achieve the connection between the connecting hollow block 29 and the block 27 on the other side, and then fix the L-shaped plate 21 with the locking bolts on the L-shaped plate 21 to prevent it from moving, thereby achieving the overall stability of the calibrator, ensuring accurate alignment during container stacking, and improving operational convenience and safety.

[0027] like Figure 5 , Figure 6 and Figure 8As shown, the anti-slip component 5 includes a second L-shaped support frame 51 fixed at the middle of one side edge of the angle plate 1, a trapezoidal block 52 is slidably connected inside the second L-shaped support frame 51, a clamping plate 53 is fixedly connected to one side of the trapezoidal block 52, a T-shaped block 56 is fixedly connected to one side of the second L-shaped support frame 51, a second movable plate 54 is slidably connected to the outer surface of the T-shaped block 56, a slot 55 is provided in the middle of the second movable plate 54, a mounting plate 511 is fixedly connected to the top of the second movable plate 54 near the second L-shaped support frame 51, a fourth spring 512 is fixedly connected to the top of the mounting plate 511, a recovery component 58 is arranged on the top of the fourth spring 512, a contact rod 57 is slidably arranged on the recovery component 58, and an automatic locking component is arranged in the middle of the second L-shaped support frame 51 near the second movable plate 54.

[0028] The automatic locking component includes a first ratchet bar 513 fixed in the middle of the second L-shaped support frame 51 close to the second movable plate 54 and two second telescopic rods 510 sliding on the inner bottom of the second movable plate 54, the outer surface of the second telescopic rod 510 is sleeved with a third spring 59, and the two second telescopic rods 510 are fixedly connected to the second ratchet bar 514 on one side close to the first ratchet bar 513.

[0029] A limiting plate for preventing the third spring 59 from falling off is disposed on one side of the third spring 59 , the first ratchet bar 513 and the second ratchet bar 514 are meshed with each other, and the third spring 59 is located between the second movable plate 54 and the limiting plate.

[0030] When the container building moves down, it contacts with the contact rod 57 in advance. In order to prevent the corner plate 1 from sliding down, the corner plate 1 needs to provide sufficient supporting force. Insufficient supporting force will cause the corner plate 1 to move down outside the container, causing the corner plate 1 to move down from the top of the container building to the bottom of the container building, making it impossible to effectively limit the container. When the container is falling, it will contact the top of the two contact rods 57 in advance and push the contact rods 57 downward. Since the fourth spring 512 has a certain supporting force, the second movable plate 54 is driven to move downward on the outside of the T-shaped block 56 through the mounting plate 511. The second movable plate 54 will contact the inclined surface of the trapezoidal block 52. Under the action of the inclined surface, the trapezoidal block 52 is pushed close to the container building, and the clamping plate 53 is firmly squeezed on the outside of the container building. At this time, the fourth spring 512 is still in a normal state. Under the action of the two clamping plates 53, the two corner plates 1 can be tightly fixed on the outside of the container building. While moving under the second movable plate 54, the second ratchet bar 514 is driven to move downward. The oblique sides of the teeth of the second ratchet bar 514 slide with the oblique sides of the teeth of the first ratchet bar 513, which can ensure that the second ratchet bar 514 and the second movable plate 54 cannot move upward, thereby ensuring the fit between the clamping plate 53 and the container, effectively improving the stability of the calibrator.

[0031] like Figure 7 and Fig. 9 As shown, the recovery component 58 includes a bottom plate 584 that slides on the top of the second movable plate 54 near the second L-shaped support frame 51 and a through groove 585 opened at the top inside the second movable plate 54, the top of the bottom plate 584 is fixedly connected with a vertical plate 583, the outer surface of the vertical plate 583 is slidably connected with a contact rod 57, the lower surface of the contact rod 57 is opened with a groove 581, one side of the inner surface of the groove 581 is fixedly connected with a second spring 582, one side of the second spring 582 is mutually connected with one side of the vertical plate 583, the vertical plate 583 is located inside the groove 581, and the bottom of the bottom plate 584 is fixedly connected with the top of the fourth spring 512.

[0032] However, when the container building continues to fall, the contact rod 57 is always located at the bottom of the container building. When the containers are stacked, the contact rod 57 will be squeezed, making it impossible to remove the contact rod 57 and the corner plate 1, and causing the container building to be unstable when stacked; To this end, as the container building continues to fall, the contact rod 57 will continue to be squeezed downward. At this time, the clamping plate 53 is already in tight contact with the container building, and the second movable plate 54 cannot move further downward. The force on the contact rod 57 continues to increase, and the fourth spring 512 is deformed and compressed. At this time, the contact rod 57 will push the bottom plate 584 to move up and down on the second movable plate 54, and the contact rod 57 and the second movable plate 54 will be relatively displaced. When the contact rod 57 moves to the through groove 585, the second spring 582 in a stretched state quickly contracts, pulling the contact rod 57 to move toward the inside of the through groove 585, so that the contact rod 57 is quickly removed from the bottom of the container building, so that the contact rod 57 can be removed without manual operation, which greatly improves convenience. This design realizes the automatic recovery of the contact rod 57 when the containers are stacked through the elastic retraction characteristics of the second spring 582, eliminating the need for manual intervention.

[0033] like Figure 2 As shown, the limiting assembly 3 includes two second fixed plates 310 fixed on both sides of the angle plate 1 close to each other, a first fixed plate 31 fixed on the top of the corner of the angle plate 1, a transmission screw 36 rotated in the middle of both sides of the angle plate 1, and a support plate 38 fixed in the middle of the top of both sides of the angle plate 1, the outer side of the support plate 38 is slidably connected with the first movable plate 37, a guide wheel 39 is provided on one side of the first movable plate 37, one side of the transmission screw 36 passes through the first movable plate 37 and is connected to each other by threads, the outer surface of the transmission screw 36 is fixedly connected with a worm gear 35, the internal rotation of the first fixed plate 31 is connected to the crown gear 32, the internal rotation of the second fixed plate 310 is connected to the worm 34, and one side of the worm 34 is fixedly connected to the third gear 33.

[0034] The third gear 33 is located below the crown gear 32, the third gear 33 and the crown gear 32 are meshed with each other, the worm 34 and the worm wheel 35 are meshed with each other, a turning handle is provided inside the first fixed plate 31, the crown gear 32 is located at the bottom of the turning handle, and a measuring component 4 for measuring the displacement distance of the guide wheel 39 is provided on one side of the angle plate 1 near the transmission screw 36.

[0035] After the calibrator is spliced ​​and installed, since the calibrator fits tightly with the container building, the container building needs to be stable when it falls and is stacked to avoid sliding friction between the container building and the corner plate 1, which causes scratches on the four sides. When the container building continues to move down, the four sides will contact the four guide wheels 39 at the same time to ensure that the container building descends smoothly between the four guide wheels 39 and reduce the shaking caused by external factors. Therefore, when the container building falls between the corner plates 1, the sliding friction between the corner plates 1 and the container building is reduced as much as possible to avoid scratches and damage to the surface of the container building. When the crown gear 32 is rotated, the worm 34 is driven to rotate by the two third gears 33 at the same time, and then the two transmission screws 36 are driven to rotate synchronously by the worm gear 35. Under the action of the thread, the displacement of the first moving plate 37 is realized to ensure the synchronous displacement of the guide wheels 39, and the stacking of small-sized container buildings can be achieved to ensure that the limiting effect of the guide wheels 39 is maximized to avoid the shaking container building from generating a huge impact force on the container building on the bottom, further improve the stacking stability, and ensure operational safety.

[0036] like Figure 4 As shown, the measuring assembly 4 includes a first L-shaped support frame 45 fixed on one side of the angle plate 1 near the fixed block 26, a second gear 42 rotated on one side of the angle plate 1 near the transmission screw 36, and a first gear 41 fixed on the outer surface of the transmission screw 36, a reading disk 44 is fixedly connected to the top of the first L-shaped support frame 45, a transmission shaft is fixedly connected to the front side of the second gear 42, and one side of the transmission shaft passes through the reading disk 44 and is fixedly connected to a pointer 43.

[0037] The second gear 42 meshes with the first gear 41 . The diameter of the second gear 42 is greater than that of the first gear 41 . The reading disk 44 is located in front of the second gear 42 . The pointer 43 fits the surface of the reading disk 44 .

[0038] However, in actual use, it can be ensured that the two guide wheels 39 on the same angle plate 1 move, but it is impossible to ensure that the two guide wheels 39 on the other angle plate 1 move synchronously, resulting in a decrease in stacking accuracy. For this purpose, a measuring component 4 is provided, which can intuitively feel the displacement distance of the guide wheel 39. While the transmission screw 36 rotates, the first gear 41 is driven to rotate synchronously. The rotation of the first gear 41 drives the second gear 42 to rotate, and then the pointer 43 and the second gear 42 rotate synchronously. The number on the reading disk 44 corresponding to the pointer 43 when it stops is the displacement distance of the guide wheel 39, thereby ensuring that the two guide wheels 39 on the two angle plates 1 can achieve precise synchronous displacement, ensure stacking accuracy, improve the stability of the overall structure, avoid potential risks caused by displacement deviation, and ensure safe and reliable operation.

[0039] Method of use: First, enclose the two angle plates 1 on the outside of the container building, insert the connecting hollow block 29 between the two clamping blocks 27, and buckle the two C-shaped blocks 25 on the outside of the clamping block 27 by squeezing the push block 24 to achieve the connection between the connecting hollow block 29 and the clamping block 27, and then fix the L-shaped plate 21 by the locking bolt to complete the quick connection of the two angle plates 1. When the container building is lowered, it contacts the contact rod 57 in advance, and through the transmission of the fourth spring 512 and the second moving plate 54, it can drive the clamping plate 53 to contact and clamp with the surface of the bottom container building to ensure the stability of the angle plate 1. At the same time, the deformation of the fourth spring 512 plays a certain buffering role on the container building. Then, through the mutual cooperation between the various components of the limit assembly 3, the guide wheel 39 can be fine-tuned to ensure that the container building can be effectively limited and buffered when it moves downward, avoiding the offset and collision of the container building, and causing impact on the container building below. By setting up the measuring component 4, the displacement distance of the guide wheel 39 can be clearly observed to ensure that the guide wheels 39 on the two corner panels 1 can be moved to the correct position, thereby avoiding the shaking of the container building caused by the guide wheels 39 being in different positions.

[0040] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
