Description

Technical Field

[0001] The invention relates to the technical field of lifting equipment, and in particular to an anti-unhooking wheat storage bin transport lifting machine. Background Art

[0002] At present, wheat is generally stored in material towers. When installing the material towers, a lifting device is needed to lift the material towers to the designated placement location. Before lifting the material towers, a lifting rope on the lifting device is usually passed through the inlet end of the material tower and then passed through the outlet end of the material tower. Then a piece of wood is tied to the lifting rope passing through the outlet of the material tower, so that the wood is used as a fixing part to clamp the outlet end of the material tower. Then, it is lifted by the lifting device and transferred to the designated placement location. However, after the material tower is lifted in this way, the center of gravity of the material tower is unstable due to the ladder, support angles, protection rings and other parts provided on the outside of the material tower. When lifting, the material tower will tilt to one side. When the material tower is lowered, one foot of the inclined side of the material tower will contact the ground first, causing the material tower to easily tip over after being placed, causing damage to the material tower. Therefore, when lifting the material tower, manual assistance is usually required. However, the material tower is heavy, and manual assistance poses a safety hazard. Summary of the invention

[0003] In order to overcome the disadvantages that the center of gravity of the material tower is unstable due to the parts such as ladders, support angles and protection rings being arranged on the outside of the material tower, the material tower will tilt to one side when lifted, and when the material tower is lowered, one base of the inclined side of the material tower will contact the ground first, which makes the material tower easy to tip over after being placed, causing damage to the material tower, the present invention provides an anti-decoupling wheat storage bin transfer crane.

[0027] Here is how the above example works: When the present invention is in use, the hanging plate 1 is connected with the boom bolts of the external crane, and then the crane is manually controlled to move so that the hanging plate 1 is located above the storage bin 200, and then the crane is controlled to lower the hanging plate 1, and at the same time the three motors 2 are controlled to drive the corresponding reels 3 to rotate, so that the sling 4 wound on the reel 3 is lowered, and then the splint 1 5, bolt 1 6, splint 2 7 and bolt 2 8 are synchronously moved downward, and the splint 1 5 and splint 2 7 are moved to the connection between the storage bin 200 and the base frame 300 and stop; it should be noted that the splint 1 5 and splint 2 7 connected to the two slings 4 on the same reel 3 are staggered, that is, the splint 1 5 connected to one of the slings 4 is directly opposite to the splint 2 7 connected to the other sling 4, such as Figure 4 As shown; after the splint 1 5 and the splint 2 7 are moved to the connection between the storage bin 200 and the base frame 300, the spacing between the splint 1 5 and the corresponding splint 2 7 is adjusted by manually tightening the bolt 1 6 to adapt to the width of the base frame 300, and then the splint 1 5 and the corresponding splint 2 7 are moved toward the corresponding base frame 300 so that the base frame 300 is located between the splint 1 5 and the corresponding splint 2 7, and then the splint 1 5 and the splint 2 7 connected by the two slings 4 on the same reel 3 are plugged together, and the splint 1 5 is inserted into the slot 7001 of the splint 2 7 so that the splint 1 5 connected by one of the slings 4 is plugged into the splint 2 7 connected by the other sling 4, and then the bolt 2 8 is manually tightened to fix the splint 1 5 and the splint 2 7 plugged together, as shown Figure 2 As shown, the clamping plate 1 5 and the clamping plate 2 7 connected to the two slings 4 on the same reel 3 are clamped on the corresponding chassis 300, as shown in FIG. Figure 5As shown, the remaining clamps 1 5, bolts 1 6, clamps 2 7 and bolts 2 8 are clamped on the corresponding base frame 300 in the same way as above. When all the clamps 1 5, bolts 1 6, clamps 2 7 and bolts 2 8 have clamped the base frame 300, the external crane is controlled to pull the lifting plate 1 upward, so that the lifting plate 1 pulls the motor 2, the winder 3, the sling 4, the clamps 1 5, the bolts 1 6, the clamps 2 7, the bolts 2 8, the storage bin 200 and the base frame 300 move upward synchronously, so that the storage bin 200 and the base frame 300 leave the ground. It should be noted that during the lifting process, the clamps 1 5 and the clamps 2 7 first move upward and are clamped at the connection between the bottom inclined surface of the storage bin 200 and the base frame 300; then the external crane is manually controlled to rotate, so that the storage bin 200 and the base frame 300 stop when they move to the top of the placement location, and then the external crane is controlled to lower the lifting plate 1, the motor 2, the winder 3, the sling 4, The device 3, the sling 4, the splint 1 5, the bolt 1 6, the splint 2 7, the bolt 2 8, the storage bin 200 and the base frame 300, so that the storage bin 200 and the base frame 300 are lowered to the placement location to complete the transportation of the storage bin 200. In the above work, the present invention lifts the storage bin 200 through multiple fixed points, which is more stable than the existing lifting of the storage bin 200 with a lifting rope and a wooden stick. In addition, the present invention distributes multiple fixed points of the storage bin 200 and the base frame 300 in a circular shape during lifting, so that the deflection angle of the storage bin 200 and the base frame 300 is small during the lifting process. At the same time, during the lifting process, the sling 4 distributed on the outside of the storage bin 200 limits the lifting process of the storage bin 200 to avoid shaking of the storage bin 200 during the lifting process, which is beneficial for the storage bin 200 and the base frame 300 to remain stable after being lowered to avoid falling and damage.

[0028] At the same time, by setting the fixed point connecting the sling 4 and the splint 5 on the side close to the storage bin 200, the sling 4 fits against the outer side of the storage bin 200 when tightened, so that the sling 4 has a better restriction effect on the outer side of the storage bin 200, the deflection of the storage bin 200 is reduced, and the lifting process is more stable.

[0029] Considering that the storage bin 200 is heavy, when the storage bin 200 is lifted by the plywood 1 5 and the plywood 2 7 and the plywood 1 5 and the plywood 2 7 move upward along the bottom frame 300, the plywood 1 5 and the plywood 2 7 will rub against the bottom frame 300, causing wear of the bottom frame 300. Therefore, by arranging a sponge layer 9 on the plywood 1 5 and the plywood 2 7, when the plywood 1 5 connected to one of the slings 4 is plugged into the plywood 2 7 connected to the other sling 4, the sponge layer 9 will fit together with the bottom frame 300 and fill the groove on the bottom frame 300, thereby increasing the friction. The sponge layer 9 is used as a buffer to prevent splint 1 5 and splint 2 7 from directly contacting the bottom slope of the storage bin 200, which would cause the splint 1 5 and splint 2 7 to squeeze and damage the bottom slope of the storage bin 200.

[0030] At the same time, in order to further improve the stability, when the bolt 1 6 is manually turned to adjust the distance between the clamp plate 1 5 and the corresponding clamp plate 2 7, and the bolt 2 8 is manually turned to adjust the distance between the two adjacent clamp plates 1 5, so that the clamp plate 1 5 and the clamp plate 2 7 are stuck on the corresponding base frame 300, the clamp plate 1 5, bolt 1 6, clamp plate 2 7 and bolt 2 8 are described as a fixed structure below. When the fixed structure is stuck on the corresponding base frame 300, the three motors 2 are controlled to drive the corresponding reel 3 to reel in the corresponding sling 4, so that the sling 4 drives the fixed structure to move upward. When the fixed structure rises to the angle connected to the bottom slope of the storage bin 200 and the base frame 300, the fixed structure is stuck by the angle between the storage bin 200 and the base frame 300. It is unable to continue to move upward with the sling 4. At this time, as the motor 2 continues to reel up the corresponding sling 4 through the reel 3, the sling 4 will pull the reel 3 downward, and the reel 3 moves downward along the connecting rod 1002 through the connecting disk 1001. When the connecting disk 1001 moves downward, it drives the connecting plate 10 to move downward, so that the connecting plate 10 contacts the upper part of the storage bin 200, and the connecting plate 10 applies pressure to the upper part of the storage bin 200, so that the splint 1 5 and the splint 2 7 and the connecting plate 10 fix the storage bin 200 in both directions, so that the storage bin 200 is more stable after being lifted by the external crane, and the stability during lifting is further improved; it should be noted that during the lowering process of the sling 4, the sling 4 moves in the through groove 101 on the lifting plate 1.

[0031] It is also considered that there is an angle between the bottom of the upper conical surface of the storage bin 200 and the reel 3, so that the sling 4 does not contact the upper conical surface of the storage bin 200. In order to further improve the stability, before lifting, the bolt three 12 and the nut 14 are loosened manually using a wrench, and the height of the sliding plate 11 is adjusted upward or downward according to the height of the upper inlet end of the storage bin 200, and the rotation angle of the squeezing roller 13 is adjusted by twisting, and then the bolt three 12 and the nut 14 are tightened manually using a wrench. When the connecting plate 10 moves downward, the squeezing roller 13 is driven to move downward synchronously, so that the squeezing roller 13 squeezes the sling 4 until it fits the upper conical surface of the storage bin 200. At the same time, the sling 4 is completely in contact with the upper conical surface of the storage bin 200, which further improves the stability of the storage bin 200 during transportation. At the same time, a limiting roller 15 is provided and the limiting roller 15 is manually pushed to slide on the squeezing roller 13, so that the limiting roller 15 is aligned with the corresponding sling 4, and the screw hole 2 1501 on the limiting roller 15 is aligned with the screw hole 1 1301 on the squeezing roller 13, and then fixed by a fixing bolt. When the connecting plate 10 moves downward, it drives the squeezing roller 13 and the limiting roller 15 to move downward synchronously, so that the limiting roller 15 clamps the corresponding sling 4 to prevent the sling 4 from swinging when the storage bin 200 is lifted and then swinging, thereby affecting the lifting stability. Example 2

[0032] On the basis of Example 1, Figure 3 As shown, rollers 16 are also included; two rollers 16 are rotatably connected in each through slot 101, and each roller 16 is in contact with the corresponding sling 4.

[0033] A baffle 17 is also included; a baffle 17 is connected to the bottom of the connecting plate 10, and an annular groove 1701 is opened at the bottom of the baffle 17.

[0034] In order to limit and protect the upper part of the storage bins 200 of different sizes, the connecting plate 10 is bolted to the baffle plate 17 .

[0035] Here is how the above example works: At the same time, considering that the sling 4 will always rub against the through groove 101 when it moves in the through groove 101 on the hanging plate 1, causing the sling 4 to be easily damaged by friction, thereby reducing the service life. Therefore, by arranging a roller 16 in the through groove 101, the sling 4 is in contact with the roller 16. When the sling 4 slides in the through groove 101, the sling 4 will cause the roller 16 to rotate, thereby reducing the degree of friction damage to the sling 4, which is beneficial to increasing the service life of the sling 4. At the same time, when the connecting plate 10 moves downward to apply pressure to the upper part of the storage bin 200, the connecting plate 10 will squeeze the upper part of the storage bin 200, and the upper part of the storage bin 200 is The mouth end and the inlet end are squeezed by the connecting plate 10 and are easily deformed, resulting in damage to the inlet end. Therefore, a baffle 17 is provided at the bottom of the connecting plate 10, and the baffle 17 replaces the connecting plate 10 to apply pressure to the upper part of the storage bin 200, and an annular groove 1701 is provided at the bottom of the baffle 17. During the process of the baffle 17 applying pressure to the upper part of the storage bin 200, the upper part of the storage bin 200 is located in the annular groove 1701, and the upper part of the storage bin 200 is wrapped and restricted by the annular groove 1701 to avoid the problem of deformation and damage of the upper part of the storage bin 200 caused by the connecting plate 10 when moving downward to apply pressure to the upper part of the storage bin 200.

[0036] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
