Description

Technical Field

[0001] The invention relates to the technical field of workshop storage racks, and in particular to an ultra-long shaft balanced load placement device. Background Art

[0002] Due to their special size, extra-long shafts are usually stored on specific racks in the storage workshop, such as long racks. During storage, if the extra-long shafts are placed unbalanced, their own weight may cause excessive local force, causing bending or twisting deformation, affecting their straightness and rotation accuracy. In addition, unbalanced placement may cause the shafts to roll or collapse due to external forces during stacking or storage, posing a safety hazard to surrounding personnel and equipment.

[0007] As a preferred technical solution of the present invention, it also includes a plurality of spring sheets, and the spring sheets are fixedly connected between adjacent card blocks.

[0008] As a preferred technical solution of the present invention, the support frame is fixedly connected by bolts with an anti-falling cover for fixing the extra-long shaft.

[0009] As a preferred technical solution of the present invention, it also includes square shafts symmetrically distributed along the base, the square shafts are rotatably connected to the base, the square shafts are fixedly connected to a bracket for limiting the adjacent support frames, the base is threadedly connected to connecting screws symmetrically distributed along the base, and the connecting screws are slidably connected to the adjacent square shafts.

[0010] As a preferred technical solution of the present invention, it also includes a second rotating handle corresponding to the connecting screw rod, and the second rotating handle is rotatably connected to the corresponding connecting screw rod.

[0016] Beneficial effects:

[0017] Compared with traditional placement racks, this super-long shaft balanced load placement device dynamically detects the distribution of the load on the shaft through the placement rack, and automatically adjusts to maintain the load balance. When the super-long shaft is first placed on the support rack, a certain point will not receive a brief impact due to priority contact of a certain section of the super-long shaft, causing the support point to be damaged, or even destroyed in serious cases.

[0018] The automatic balancing system of this extra-long shaft balanced load placement device ensures that the shaft is always in a stable state. Even if there is vibration or external force in the workshop, it can reduce the risk of shaft rolling or tilting, protecting the safety of employees and surrounding equipment.

[0019] The balanced load of the extra-long shaft also has the advantage of being placed in long-term storage. Fatigue failure at a certain point will not cause the failure of the support point, thereby causing the extra-long shaft to tilt or even slide. Instead, when a certain point fails, the support frame will slightly swing back and forth to allow the failed point to be re-supported, thereby maintaining support for each point.

[0020] The present invention stacks up multiple balanced load placement devices that have been placed with extra-long shafts, thereby efficiently utilizing the height and space of the workshop. Compared with the traditional stacking method, it can reduce the ground area occupied, optimize the workshop layout and material management, and by rotating the first handle, the card block can be inserted into the card slot of the adjacent connecting block, so that two adjacent balanced load placement devices can be spliced ​​and fixed, which is simple to operate and improves the stability during stacking.

[0021] The present invention rotates the second rotating handle so that the bracket rotates and is clamped in the supporting frame of the balanced load placement device below, thereby limiting the supporting frame. At the same time, the connecting screw rod can achieve a real-time locking effect, thereby improving the stability of long-term storage and avoiding collapse caused by shaking of the supporting frame.

[0022] The present invention can quickly enhance the supporting force in the middle of adjacent balanced load placement devices through the provision of a storage frame, a connecting rod, a second connecting frame and a guide block, thereby avoiding stress concentration in the middle. The operation is simple and convenient for rapid splicing and disassembly and storage.

[0023] The present invention uses a screwdriver to twist the third handle on the lower side, so that the stop block on the lower side moves downward to contact the ground. In this way, the device can adapt to the uneven floor of the workshop and make the entire device more balanced.

[0024] The invention connects the weight block to one side of the support frame near the middle by a pull rope, so that the center of gravity of the entire device is located in the middle, thereby making it more stable when carrying an extra-long shaft and effectively resisting tipping.

DETAILED DESCRIPTION

[0041] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope and application scope of the present invention are not limited.

[0042] Embodiment 1: A device for placing a balanced load on an extra-long shaft, such as Figures 1 to 5As shown, it includes a base 1, the top of the base 1 is rotatably connected to a support frame 11 symmetrically distributed along the base 1, the top of the base 1 is fixedly connected to a limiter 12 symmetrically distributed along the support frame 11, when the support frame 11 swings excessively, it contacts the adjacent limiter 12, and the limiter 12 is used to limit the swing range of the support frame 11, an extra-long shaft 13 is placed between the symmetrically distributed support frames 11, and the left and right sides of the support frame 11 are fixedly connected by bolts with an anti-drop cover for fixing the extra-long shaft 13, the front and back sides of the top of the base 1 are fixedly connected to a first connecting frame 14 symmetrically distributed along the base 1, and the upper middle of the first connecting frame 14 is rotatably connected to a first The turning handle 15 and the front and rear sides of the bottom of the base 1 are fixedly connected with connecting blocks 16, and the connecting blocks 16 are provided with grooves symmetrical along the connecting blocks 16. By connecting the first connecting frame 14 on one base 1 with the connecting block 16 on the other base 1, the two bases 1 can be spliced ​​and stacked up and down. The first connecting frame 14 is close to the side of the adjacent first turning handle 15 and is slidably connected with the left and right mirror-distributed blocks 17. The end of the first turning handle 15 is fixedly connected with a top block 18. When the top block 18 rotates, the convex surface of the top block 18 squeezes the adjacent blocks 17 away, so that the blocks 17 and the grooves of the connecting block 16 are limited and matched, and spring pieces 19 are fixedly connected between the adjacent blocks 17.

[0043] The extra-long shaft 13 is placed on the left and right support frames 11 of the balanced load placement device, with a total of four support points, which will support the extra-long shaft 13 at four sides of the extra-long shaft 13 respectively. No matter which section of the extra-long shaft 13 contacts the support frame 11 first, the balanced load placement device will swing back and forth according to the weight felt first. Compared with the traditional placement frame, this extra-long shaft balanced load placement device can dynamically detect the distribution of the load on the shaft and automatically adjust to keep the load balanced. When the extra-long shaft 13 is first placed on the support frame 11, a certain point will not receive a short impact due to the priority contact of a certain section of the extra-long shaft 13, causing the support point to be damaged, or even destroyed in serious cases; and the automatic balancing system ensures that the shaft is always in a stable state. Even if there is vibration or external force in the workshop, the risk of shaft rolling or tilting can be reduced to protect the safety of employees and surrounding equipment.

[0044] It also has advantages in long-term storage. Fatigue failure of a certain point will not cause the support point to fail, thereby causing the extra-long shaft 13 to tilt or even slide. When a certain point fails, the balanced load placement device will slightly swing the support frame 11 back and forth to allow the failed point to be re-supported, thereby maintaining the support of each point.

[0045] In addition, the two vertical limiters 12 on the front and rear sides of the left and right sides of the base 1 will ensure that the swing amplitude of the support frame 11 is within a certain range, ensuring the range of activity of the support frame 11; the anti-falling cover will also ensure that the extra-long shaft 13 will not fall off due to left and right sliding when the support frame 11 swings left and right.

[0046] In addition, when a plurality of extra-long shafts 13 are stored in batches in a workshop, a plurality of balanced load placement devices on which the extra-long shafts 13 have been placed can be stacked up and down. The specific stacking method is as follows: first, the connecting block 16 of a balanced load placement device is clamped with the first connecting frame 14 of the adjacent balanced load placement device, and then the first rotating handle 15 is rotated to drive the top block 18 to rotate. The convex surface of the top block 18 squeezes the adjacent clamping block 17, and the spring piece 19 is deformed until the clamping block 17 is clamped into the clamping groove of the connecting block 16. In this way, the connecting block 16 is fixed to the adjacent first connecting frame 14, thereby fixing the two adjacent balanced load placement devices stacked up and down, and the fixation can be released by rotating the first rotating handle 15 in the opposite direction.

[0047] That is, the present invention efficiently utilizes the height and space of the workshop by stacking up and down a plurality of balanced load placement devices on which extra-long shafts 13 have been placed. Compared with the traditional stacking method, it can reduce the ground area occupied, optimize the workshop layout and material management, and by turning the first handle, the card block 17 can be inserted into the card slot of the adjacent connecting block 16, so that two adjacent balanced load placement devices can be spliced ​​and fixed. The operation is simple and the stability during stacking is improved.

[0048] Embodiment 2: Based on embodiment 1, Figures 6 to 9 As shown, it also includes square shafts 22 symmetrically distributed along the left and right sides of the base 1, the square shafts 22 are rotatably connected to the base 1, the inner ends of the square shafts 22 are fixedly connected to a bracket 21 for limiting the adjacent support frame 11, and the left and right sides of the base 1 are both threadedly connected to connecting screws 23 symmetrically distributed along the front and back of the base 1, the connecting screws 23 are slidably connected to the adjacent square shafts 22, and the outer ends of the connecting screws 23 are rotatably connected to the second handle 2.

[0049] When placing the extra-long shaft 13, it is necessary to rotate the support frame 11 to automatically and evenly place the extra-long shaft 13. When the extra-long shaft 13 is subsequently stacked up and stored for a long time, in order to improve the stability of long-term storage and avoid collapse caused by the shaking of the support frame 11, the support frame 11 needs to be fixed. The specific operation is as follows: by rotating the second turning handle 2, the connecting screw 23 is driven to rotate, and then the square shaft 22 is driven to rotate, and then the bracket 21 is driven to rotate and be stuck in the support frame 11 of the balanced load placement device below, so as to limit the support frame 11, and at the same time, the connecting screw 23 can play a real-time locking effect.

[0050] like Fig.10 and Fig.11 As shown, it also includes a storage frame 3 symmetrically distributed along the front and back of the base 1, the storage frame 3 is fixedly connected to the middle of the base 1, the right side of the storage frame 3 is rotatably connected to a connecting rod 31, the end of the connecting rod 31 is fixedly connected to a second connecting frame 32, the second connecting frame 32 has a C-shaped groove, and the side of the base 1 close to the storage frame 3 is fixedly connected to a guide block 33 for limiting the second connecting frame 32, the second connecting frame 32 is clamped on the guide block 33 through the C-shaped groove, thereby supporting the middle part of the base 1.

[0051] Since the balanced load placement device is only supported on the left and right sides, but not in the middle, and the super-long shaft 13 is very long, stress is easily concentrated in the middle, resulting in overall instability. Therefore, it is necessary to strengthen the supporting force in the middle, specifically:

[0052] After the two balanced load placement devices are spliced ​​and fixed, the connecting rod 31 is rotated upward, and the connecting rod 31 drives the C-shaped groove of the second connecting frame 32 to be clamped on the guide block 33. In this way, the middle part of the adjacent balanced load placement device is supported by the connecting rod 31. When the adjacent balanced load placement device needs to be disassembled, the connecting rod 31 is rotated downward, and the connecting rod 31 drives the C-shaped groove of the second connecting frame 32 to disengage from the guide block 33. Finally, the connecting rod 31 drives the second connecting frame 32 to be stored in the storage frame 3.

[0053] In summary, the present invention can quickly enhance the supporting force in the middle of adjacent balanced load placement devices through the arrangement of the storage frame 3, the connecting rod 31, the second connecting frame 32 and the guide block 33, thereby avoiding stress concentration in the middle. The operation is simple and convenient for quick splicing and disassembly and storage.

[0054] Embodiment 3: Based on embodiment 2, Fig.12 and Fig.13 As shown, it also includes a stop block 41 symmetrically distributed along the base 1, the stop block 41 is slidably connected to the base 1, a shaft sleeve 42 is fixedly connected in the middle of the stop block 41, a threaded rod 43 is connected to the inner thread of the shaft sleeve 42, and the base 1 is rotatably connected to a third rotating handle 4 symmetrically distributed along the base 1, and the threaded rod 43 is fixedly connected to the adjacent third rotating handle 4.

[0055] When the workshop floor is uneven, lift up the lower side of the base 1 so that the base 1 is placed on the workshop floor in a balanced manner, and then use a screwdriver to turn the third handle 4 on the lower side to drive the threaded rod 43 on this side to rotate, and then the sleeve 42 on this side moves downward, and then drives the stop block 41 on this side to move downward until it contacts the ground. In this way, it can adapt to the uneven condition of the workshop floor and make the entire device more balanced.

[0056] like Fig.14 and Fig.15 As shown, it also includes telescopic rods 51 symmetrically distributed along the base 1, there are four telescopic rods 51 in total, the telescopic rods 51 are fixedly connected to the middle of the base 1, weight blocks 5 are fixedly connected between the telescopic ends of adjacent telescopic rods 51, and pull ropes 52 symmetrically distributed front and back along the weight blocks 5 are fixedly connected between the weight blocks 5 and the adjacent support frames 11.

[0057] The weight block 5 is connected to the side of the support frame 11 close to the middle by the pull rope 52, so that the center of gravity of the entire device is located in the middle, making it more stable when carrying the extra-long shaft 13 and effectively resisting tipping.

[0058] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
